▼ In this thesis results of satellite and in-situ airplane ozone data analysis are presented. Total Ozone Column (TOC) from Total Ozone Mapping Spectrometer (TOMS), and ozone enhancements sampled on the cruise flight route from Johannesburg to Vienna by Measurement of OZone by Inservice AIrCraft (MOZAIC) at Equatorial Africa and North Africa are investigated. The work in this thesis is focused on the study of ozone transport during stratosphere-troposphere exchange (STE) events over intense STE areas, and seasonal variability of ozone over Africa. On very few occasions, at upper troposphere Equatorial Africa ozone spikes are observed at a flying altitude of 250-200 hPa. To understand the events that attribute to spiky MOZAIC ozone and relative humidity observations, additional data sets from different data sources were used to examine the observed events. Vertical wind fields in the regions of low Outgoing Long-wave Radiation (OLR), very high latent heat and cloud liquid water content transport have indicated presence of convection and thunderstorm events. Potential vorticity intrusion over equatorial region introduced enhanced ozone of stratospheric origin, as revealed by ERA-interim ozone data. Both downwelling and upwelling induced by convection and intrusion transported enhanced ozone from the stratosphere all the way down to the boundary layer. We have distinguished source and regions of discharge of MOZAIC ozone enhancements observed at a flying altitude of 250-200 hPa over North Africa. Different data sets from ECMWF-ERA-Interim are used to examine the dynamics associated with the events. Relative humidity from MOZAIC measurement, longitudinal cross-section of potential vorticity (PV) and ozone volume mixing ratio (VMR) over the region of MOZAIC ozone enhancements confirmed that the observed enhancements are measured within lower stratosphere. This is mainly due to massive shift in the tropopause level. Longitudinal cross-section of PV, potential vorticity in isentropic surfaces (IPV) and ozone VMR revealed that the first mode of transport is large scale airmass subsidence from the stratosphere over mid-latitude. Some of these events lead to cross tropopause ozone transport xi to upper troposphere North Africa. The second case is subsidence at polar regions during North hemisphere winter seasons. IPV is strongly modified as revealed by wind fields. In addition zonal winds and Rossby waves, which are active during winter seasons, have strong contribution in modifying potential vorticity and ozone spatial and temporal distribution. TOC is analyzed from TOMS satellite data to study its seasonal variability over Africa. The seasonal variability comparisons in the latitude regions 0-34.50 N and 0-34.50 S show that ozone concentration peaks shift from April at North Africa to September near the equator. Ozone concentration begins to raise from May to October, and decreasing afterwards in the Southern part of Africa with highest peaks only between September to October. This result shows that ozone concentration… Advisors/Committee Members: Dr. Gizaw Mingistu (advisor).

▼ Nitrogen oxides (NOx = NO + NO2) play a crucial role in the formation of ozone and has significant impacts on the production of secondary organic and inorganic aerosols, thus affecting human health, global radiation budget, and climate. Accurate knowledge of NOx emissions is essential for relevant scientific research and air pollution control policies. This thesis evaluates current estimates of anthropogenic and natural NOx emissions over the United States and improves model’s prediction of surface ozone concentrations by using a 3-D Regional chEmistry and trAnsport Model (REAM) and various types of observations and investigate the impact of thunderstorms on surface NOx and O3 concentrations. The diurnal cycle of NO2 is a function of emissions, advection, deposition, vertical mixing, and chemistry. Its observations, therefore, provide useful constraints in our understanding of these factors. The REAM simulated diurnal cycles are evaluated by using the DISCOVER-AQ campaign measurements, EPA Air Quality System (AQS) observations, and OMI and GOME-2A tropospheric vertical column densities (TVCDs) products in July 2011 over the Baltimore-Washington region. The model simulations are in reasonably good agreement with the observations except that PANDORA measured NO2 TVCD show much less variation in the early morning and late afternoon than simulated in the model. High resolution (4 km in the horizontal) model simulations are also performed to examine the effects of emission distributions. The overestimation of NO2 concentrations from the 4-km REAM simulation in contrast to the well reproduction of observations by the 36-km REAM suggests that the 2011 National Emission Inventory (NEI2011) provide a good estimate of NOx emissions at the 36-km scale but can’t resolve NOx emission distributions at the 4-km resolution. By analyzing model simulations with the observations, the thesis shows that the diurnal emission profile of NOx is different over the weekend from the weekdays and that weekend emissions are about 1/3 lower than weekdays. Observed ozone concentrations can be used to evaluate NOx and volatile organic compound (VOC) emissions by using their relationships with ozone concentrations. The thesis shows that the time when ozone reaches its daily maximum (peak time) is also related to NOx and VOC emissions. Through model sensitivity analyses of REAM in July 2011 over the contiguous United States (CONUS), it is found that ozone peak values are more sensitive to NOx emissions while ozone peak time is more sensitive to VOC emissions in the eastern United States. By such relationships and the comparison between observations and model results, we find that the underestimation of soil NOx emissions leads to a low bias of simulated ozone peak value in the South, while the overestimation of biogenic isoprene emissions results in earlier than observed ozone peak time in the Central, South and Southeast regions. The simulated formaldehyde columns, which are higher than satellite measurements, confirm the latter. We illustrate the… Advisors/Committee Members: Wang, Yuhang (advisor), Huey, Greg (committee member), Weber, Rodney (committee member), Ng, Nga Lee (committee member), Kaiser, Jennifer (committee member).

Ozone (O3,) produced in the troposphere plays a vital role in the radiative and chemical processes of the atmosphere due to its strong oxidizing capability.Subsequently, surface O3 is one of the ideal trace gases present in the troposphere which can modulate the chemistry to a larger extent. Being a prominent green house gas and a good tracer with fairly small lifetime, the variation in the abundance of ground level O3is an ideal method to explore the photochemistry and dynamics of the atmosphere. The chemistry that leads to tropospheric O3 formation is generally initiated by the photolysis of NO2. In the presence of solar radiation NO2 photolysis to produce NO and atomic oxygen and this atomic oxygen reacts with O2 to produce O3. The conversion of NO to NO2 without O3 occurs through a combination of the reaction cycles of hydroxyl (OH) or peroxyl radicals (HO2). In these cycles, OH radicals are converted to HO2 or RO2, through their reaction with CO or hydrocarbons. The increasing trends in ground levelO3 in the urban and rural areas of industrialized regions are strongly linked to the changes in anthropogenic emissions of O3 precursors and revealed that its key role in imparting global warming and subsequent climate changes. Over the last few decades, several studies have revealed that background O3 in the troposphere has almost doubled that compared to the pre industrial era. In order to explore surface O3 chemistry and its transport at Kannur, a tropical coastal site in the state of Kerala, continuous observations has been going on since 2009 at Kannur University with the support of ISRO-GBP (AT-CTM) programme. This thesis is focused on the observations on the variations of ground level O3 mixing ratio and its precursors at Kannur (11.9oN and 75.4oE, 5m asl), in north Kerala confined in the coastal belt of Arabian Sea and Western Ghats. In order to discuss the objectivity effectively, the thesis is divided into seven chapters.

▼ This study was conducted to evaluate the impact of sustained ozone dosages rates (0, 3, 13, 25, and 45 g O3 per kg feed delivered per day)on water quality profile, fish physiology, and growth during a production cycle of hybrid striped bass reared in pilot scale recirculating systems. Nitrogenous wastes and dissolved organic compounds increased linearly (p < 0.01) throughout the trial under both ozonated and unozonated conditions. Ozone treatments 13 and 25 g O3 / kg feed received 170 kg more feed than the control treatment (0 g O3 / kg feed) by the end of trial. The ozonated system received an average 1 kg more feed per day than did the unozonated system, although the unozonated system received 25% more freshwater during the trial. Ozonation increased nitrification efficiency which resulted in a 25% reduction in residual ammonia measured per kilogram of feed delivered. Biologically degradable organics (CBOD5) were lowered 45% under ozonation when adjusted for daily feed input. Microbial activity as determined by the rate of degradation of DOC was 43% higher in the ozonated environments. Increased environmental quality provided through ozonation did not result in measurable physiological improvements (p 0.05). All parameters monitored except plasma protein and hematocrit values varied significantly (p>0.05) over time. Hemoglobin, plasma protein, and hematocrit values in fish under all rearing conditions were 10.2 Â± 0.4 g/dL, 7.1Â± 0.6 g/dL, and 52.9 Â± 1.9%, respectively. Final mean serum chloride level of 115.8 Â± 3.4 mE/L and mean glucose level of 186.3 Â± 2.1 mg/dL were measured in fish reared at treatments 0, 13, and 25 g O3. Fish reared under ozonated conditions possessed an overall mean growth rate of 2.3 g/day and FCR of 1.58:1. Simultaneously, fish in the unozonated environment gained 1.8 g/day at an FCR of 1.90:1. At the conclusion of the trial, the final mean weight (443 Â± 11.6 g) of fish reared in the unozonated environment was significantly lower (p<0.01) than fish reared in the ozone treatments 13, and 25 g O3 (combined mean of 576.6 Â±16.4 g).

In the present study the combined effect of gaseous ozone treatment and other preservation food methods on physicochemical characteristics and shelf life of fruit and vegetables was investigated. The studied fruits and vegetables were: grape (cv. Sultanina), strawberry (cv. Camarosa), apricot (cv. Bebeko) and fresh-cut lettuce salad. Additionally, gamma irradiation and mild heat treatment were applied on strawberry and passive modified atmosphere packaging on bilayer film PET//LLDPE and citric acid were applied on fresh-cut lettuce salad. Weight loss, firmness, color parameters (L*, a* and b*), total soluble solids, titreatable acidity, pH, volatile compounds, sensory characteristics (appearance, taste and odor) and microbiological indexes (Total mesophilic counts, Yeast and molds counts, Enterobacteriaceae counts, Lactobacillaceae counts and fungal decay) were monitored during cold storage of the commodities above.Ozone treatment at 0,5 ppm improved appearance, taste and odour and increase the shelf life of grapes by 7 days compared to untreated grapes. The application of higher ozone concentrations 1,0 and 1,5 ppm reduce shelf life of stored grapes accelerating the degradation of appearance, taste and odor. The higher shelf life of ozone-treated grapes at 0,5 ppm could be attribute on lower percentage weight loss compared to untreated grapes and on the inhibitory effect of ozone to the tissue-browning enzymes such as polyphenol oxidase, peroxidase and phenylalanine ammonolyase.Citric acid treatment, ozonation at 0,5 ppm and ozonation at 0,5 ppm plus citric acid improved significantly the visual appearance and cut-effect tissue browning index of lettuce compared to untreated ones. Total mesophilic counts and Enterobacteriaceae counts were also reduce significantly after the application of treatments above. Yeast and molds present higher resistance on these applied treatments. An increase by 4 days was achieved in shelf life of lettuces.The application of irradiation increase shelf life of strawberry by 2 days. Same results were observed after the application of blanching, ozonation at 0,5 ppm and ozonation at 0,5 ppm plus blanching. Higher doses of gamma irradiation and ozonation accelerate the degradation of appearance and taste compared to untreated strawberries.The applied ozone concentrations of 0,5, 1,0 and 1,5 ppm improved the appearance and taste of apricots compared to untreated ones. The best results were recorded on ozone treatment at 0,5 ppm. The extension of shelf life was 5 days.As far as concerned physicochemical characteristics, pH and total soluble solids were not affected significantly by the application of ozone treatment. Ozone at low concentrations increase the firmness of fruits compared to untreated ones, while increases the lightness on account of its blanching properties. Both ozonation and irradiation affect significantly titreatable acidity of fruits.

The 2001-2002 Lawrence Berkeley National Laboratory (LBNL) nested, crossover-design study explored the operating profiles of two HVAC systems alternated over a period of approximately nine weeks, including during 2001 Fall school semester, in two pairs of classrooms sited adjacent to one another and equipped with either standard or alternate (low-emissivity) interior finish materials. The present study, a retrospective analysis, included inferring estimated indoor ozone concentrations. Because ozone can react with certain indoor pollutants to generate secondary organic aerosols, a mass-balanced based indoor/outdoor ratio expression was used to model indoor ozone to subsequently model indoor particles from possible ozone-initiated chemistry. When the advanced HVAC system, called IDEC, was running, surface (especially ceiling) reactions dominated ozone loss processes. When either of the standard HVAC systems, or Bard (different percentages of outdoor air intake) was running, damper setting and ventilation and/or gas phase reactions accounted for the majority of the indoor-outdoor ozone difference. In this study, statistical analysis indicated classroom B-A containing carpet (with polypropylene/polyolefin backing) and teaching materials (with bare surfaces) had higher fine particle number counts (PNC; PM0.3-0.5/PM0.5-0.7) than in the other study classrooms. Additionally, elevated humidity coupled with elevated estimated ozone at school A-B yielded comparatively elevated PNC. Mixed models demonstrated IDEC system use (100% outdoor air intake) at SDB-A, especially during weeks 7-9, yielded significantly greater indoor PNC (PM0.3-0.5/PM0.5-0.7) values than in the other study classrooms. Bard (50% outdoor air intake) use in both SDA classrooms (A, B) yielded comparatively greater PNC than IDEC.

Pas de résumé en français

The present study was undertaken to investigate whether vacuolar endoproteolysis and/or protein carbonylation (measured here with a newly developed method) were functionally linked and if either of these processes or both could differentiate between ozone sensitive and tolerant wheat cultivars (cvs). Two winter wheat (Triticum aestivum L.) cvs released in 1986 (Soissons) and 2006 (Premio) were grown in the field and exposed to ambient and semi-controlled chronic ozone concentrations, from pre-anthesis to harvest, using a new linear ozone fumigation device that generates gradients of the pollutant. Grain yield and quality were more affected by the ozone treatments in the older cv Soissons that appeared to be the most sensitive. Because stomatal conductance did not differ significantly between the two cvs, differential ozone sensitivity was rather ascribed to differences in the biochemical and molecular responses between the two cvs. Ozone detrimental effects were mainly characterized by premature induction of leaf senescence, causing the shortening of the assimilation and grain-filling periods. Even though Soissons exhibited higher constitutive levels of carbonyl content in total soluble proteins, the increases in protein carbonylation, in response to the ozone treatments, were equivalent in both cvs. Thus basal levels of protein carbonyl seems a more relevant parameters to distinguish between ozone sensitive and tolerant wheat cvs than actual change in this parameter in response to ozone treatments. However, ozone induced more carbonyl groups on Rubisco large subunit (LSU) and small subunit (SSU) in Soissons and this was associated with a more pronounced decline in LSU and SSU contents and a lower Rubisco activity. Increased protein carbonyl levels and losses in total chlorophyll contents were concurrent, suggesting a link between the extent of oxidative stress and senescence development. Moreover, ozone treatments induced a stimulation of endoproteolytic activities that resulted mostly from increases in cysteine protease activities, for both cvs. Surprisingly, total proteolytic and cysteine protease activities were more enhanced in the tolerant cv, whereas elevated proteolysis is usually associated with high sensitivity to environemental stresses, like drought. Expression analysis for three genes encoding papain-like cysteine proteases showed poor correlation with total cysteine protease activities, which suggested that post-transcriptional regulation mechanisms were prevalent over transcriptional ones. Increased endoproteolytic activities were associated with increased protein carbonylation and with a decline in total soluble protein contents. Oxidized proteins could be more susceptible to proteolysis. Therefore, we suggest that ozone-induced ROS caused protein oxidation on one hand and acted as a signal that triggered senescence processes, such as enhanced proteolysis, on the other hand

▼ L’ozone (O3) est un gaz reconnu comme un des polluants atmosphériques majeurs du XXIème siècle, de par ses propriétés très oxydantes. Dans les plus basses couches de notre atmosphère, ce polluant secondaire est produit par des réactions photochimiques impliquant des précurseurs émis par les activités humaines et la végétation. De nombreuses études expérimentales ont révélées le caractère phytotoxique de l’O3, qui dégrade sévèrement la photosynthèse, réduit le rendement des récoltes et inhibe la croissance des arbres. Afin de quantifier les effets de l’O3 sur les écosystèmes à l’échelle globale, des modèles numériques ont été développés. Dans cette thèse, nous avons principalement développé un nouveau modèle d’impact basé sur le concept dose/réponse au sein du modèle global de végétation ORCHIDEE. L’approche semi-mécaniste utilisée vise à représenter de manière simplifiée les effets du stress oxydatif causés par l’O3 sur la photosynthèse. L’étalonnage des paramètres a été réalisé en utilisant des données physiologiques issues majoritairement d’expériences de fumigation à l’air libre et en chambres à ciel ouvert menées pendant la saison de croissance de plusieurs espèces végétales. Cette étape de calibration a permis de déterminer les paramètres spécifiques à plusieurs types fonctionnels de plantes. La sensibilité du modèle à l’O3 et à son interaction avec le CO2 et le stress hydrique a ensuite été testée. A l’échelle locale, notre modèle d’impact reproduit fidèlement l’allure de la réponse de la photosynthèse observée in situ à l’échelle saisonnière, et l’élévation du CO2 compense partiellement l’impact de l’O3. En outre, le couplage entre la photosynthèse et la conductance stomatique dans ORCHIDEE permet de simuler la limitation des effets de l’O3 par les flux entrants. La fermeture stomatique réduit également la transpiration, ce qui augmente l’humidité du sol et préserve ainsi la végétation d’un stress hydrique accentué. Cependant, les effets observés sur la respiration autotrophe ne sont pas représentés et l’impact sur la surface foliaire est sous-estimé. Afin d’évaluer la performance du modèle, nous avons comparé l’impact simulé sur la productivité nette (NPP) annuelle avec l’effet estimé par les relations empiriques linéaires standards, recommandées par l’UNECE pour évaluer les risques phytotoxiques chez plusieurs types d’écosystèmes. En outre, à l’échelle globale, nous obtenons des résultats similaires aux estimations réalisées avec un autre modèle de végétation munie d’une paramétrisation d’impact différente. Enfin, nous estimons que les concentrations actuelles causent localement une chute de productivité nette totale annuelle allant jusqu’à 11.7% en moyenne dans le nord-est des Etats-Unis, et réduirait le contenu en carbone du sol de 10.9% dans cette région et de 42.5% en Indonésie si la pollution actuelle perdure pendant 50 ans. Ce travail indique que l’impact de l’O3 sur la végétation est non-négligeable dans le modèle ORCHIDEE, et doit être pris en compte dans les études globales du bilan de carbone… Advisors/Committee Members: Hauglustaine, Didier (thesis director), Lathière, Juliette (thesis director).

▼ Misfolded prions (PrPSc) are well known for their resistance to conventional decontamination processes. The potential risk of contamination of the water environment, as a result of the disposal of specified risk materials (SRM), has raised public concerns. Ozone is commonly utilized in the water industry for the inactivation of microbial contaminants and was tested in this research for its ability to inactivate prions (263K hamster scrapie). With the applied ozone dose of 7.6-25.7 mg/L, the efficacy of ozone inactivation of PrPSc was both pH and temperature dependent. Treatment variables included applied ozone dose (7.6–25.7 mg/L), contact time (5 s and 5 min), temperature (4°C and 20°C) and pH (pH 4.4, 6.0, and 8.0). The inactivation of PrPSc was quantified by determining the in vitro destruction of PrPSc templating properties using the protein misfolding cyclic amplification (PMCA) assay and bioassay. Highest levels of prion inactivation (≥4-log) were observed with applied ozone doses of 13.0 and 25.7 mg/L, at pH 4.4 and 20°C. The kinetic modeling of prion inactivation in phosphate buffered saline (PBS) with applied ozone dose of 10.8 mg/L at pHs and temperatures described above was characterized by both Chick-Watson (CW) and efficiency factor Hom (EFH) models. It was found that the EFH model fit the experimental data more appropriately. Based on the EFH model, CT values were determined for 2-log, 3-log, and 4-log inactivation. A comparison of ozone CT requirements among various pathogens suggests that prions are more susceptible to ozone degradation than some model bacteria and protozoa. Subsequently, the ozone inactivation of infectious prions was assessed in the raw, gravity separated and dissolved air flotation (DAF) treated rendering wastewater, and in the municipal final effluent. It was found that the organic load highly affected prion inactivation by ozone, while DAF treatment significantly removed the organics and improved the efficacy. At the applied ozone dose of 44.6 mg/L, a >4-log inactivation was achieved after 5 min of exposure in the DAF treated rendering plant wastewater. The results indicated that ozone could serve as a final barrier for prion inactivation in primary and/or secondary treated wastewater.

▼ Atmospheric fine particles and ozone (O3) are correlated with adverse health effects, visibility reduction, and climate change. In recent decades, China has suffered from the record-breaking severe haze event and elevated ozone problems. Recent field measurements show that organic carbon (OC) was one of the major components during haze events, and it has been suggested that secondary organic aerosol (SOA) could account for a significant fraction of the total observed OC. Quantitative knowledge of the contributions of different emissions sources to SOA and ozone concentrations is significant to better understand their formation mechanisms and is useful to develop the effective emission control strategies. A Community Multiscale Air Quality (CMAQ) model with source-oriented lumped SAPRC-11 (S11L) photochemical mechanism is applied to determine the contributions of anthropogenic and biogenic sources to SOA and ozone concentrations in China. In China, predicted SOA concentrations are generally higher in summer (10-15 µg· M^-3) due to large contributions of biogenic emissions within China (country average ~60%) and in winter due to industrial and residential sectors (country average ~78% total) based on the Multi-resolution Emission Inventory for China (MEIC) emission inventory. However, the transportation sector (~30-40% vs. ~5% by MEIC) is predicted to be much more important while the residential (~21-24% vs. ~42%) sector is predicted to be less important based on The Regional Emission inventory in ASia v2.1(REAS2) emissions. These discrepancies in source contributions to SOA needs to be further investigated as the country seeks optimal emission control strategies to fight severe air pollution. The ozone attribution scheme based on the three-regime definition was incorporated into the CMAQ model to quantify NOx and VOC contributions to ozone concentrations in China in August 2013. Most of the areas considered by the two-regime approach as NOx or VOC-limited are classified as transitional under the new three-regime scheme, and the scattered VOC-limited regimes are located in urban areas. This three-regime approach represents an improvement from the traditional two-regime approach with only NOx or VOC-limited regimes. This three-regime method then is applied in the ozone source apportionment as well, and it is reported that the industries, transportation, power and biogenic sources are four major emission contributors to ozone with different spatial distributions.

▼ Ozone-biological activated carbon filtration (ozone-BAC) treatment plays a major role in advanced water treatment (AWT) for potable reuse applications in locations where reverse osmosis (RO) treatment is not cost effective and/or feasible. However, regulators, designers, and operators are ambiguous about long-term ozone-BAC reliability and mechanisms involved in the removal of certain contaminants of emerging concern (CECs) such as N-Nitrosodimethylamine (NDMA) and perfluorooctanoic acid (PFOA), and bulk organics such as total organic carbon (TOC). For 16 months, two parallel BAC filters were operated at different loading rates and empty bed contact times (EBCTs) of 10 minutes and 20 minutes treating up to 60,000 and 30,000 bed volumes (BVs), respectively, of sand filtered effluent from a municipal water resource recovery facility. BAC 1 (EBCT = 10 min) and BAC 2 (EBCT = 20 min) used Filtrasorb 400 (F400) granular activated carbon (GAC) as filter media, with equal bed depths. NDMA was generated after ozonation. Longer acclimation time (140 days or 20,000 BVs) was required for non-carbon-based (e.g., biodegradation) removal of NDMA in BAC 1. Three distinct phases were observed for NDMA removal: an initial phase dominated by carbon-based mechanisms (e.g., adsorption), the second phase influenced by both carbon- and non-carbon-based mechanisms and the third phase dominated by non-carbon-based mechanisms. In BAC 1, desorption of CECs such as sulfamethoxazole, DEET, and sucralose was observed after 450 days of operation (or 60,000 BVs). In BAC 2, almost all CECs, excluding NDMA, were removed consistently throughout the study. BAC 1 effluent TOC plateaued at around 6 mg/L, whereas BAC 2 effluent plateaued at around 4 mg/L. Under plateau conditions, BAC 1 and BAC 2 appear to have a gross TOC removal potential of around 0.2 to 0.3 kg/d/m3 of carbon. A comparative analysis of findings from this study and results from a past ozone-BAC study shows that higher TOC removal capacity was observed in BAC with shorter EBCT and upstream sand filter compared to BAC with longer EBCT and upstream membrane filter. TOC-based specific UV absorbance (SUVA) was recommended for continuous online monitoring of ozone-BAC performance.

▼ Tropospheric O3 and CO are major pollutants in the troposphere. Strong correlation between O3 and CO was observed during the DISCOVER-AQ aircraft experiment in July 2011 over the Washington-Baltimore area. The observed correlation does not vary significantly with time or altitude in the boundary layer. The observations are simulated well by a regional chemical transport model. We analyze the model results to understand the factors contributing to the observed O3-CO regression slope, which has been used in past studies to estimate the anthropogenic O3 production amount. We trace separately four different CO sources: primary anthropogenic emissions, oxidation of anthropogenic VOCs, oxidation of biogenic isoprene, and transport from the lateral and upper model boundaries. Modeling analysis suggests that the contribution from biogenic isoprene oxidation to the observed O3-CO regression slope is as large as that from primary anthropogenic CO emissions. As a result of decrease of anthropogenic primary CO emissions during the past decades, biogenic CO from oxidation of isoprene is increasingly important. Consequently, observed and simulated O3-CO regression slopes can no longer be used directly with an anthropogenic CO emission inventory to quantify anthropogenic O3 production over the United States. The consistent enhancement of O3 relative to CO observed in the boundary layer, as indicated by the O3-CO regression slope, provides a useful constraint on model photochemistry and emissions. As an extension, we analyze the scenario of O3-CO regression slopes in the entire United States and China regions. The O3-CO regression slope ~ 0.3 is simulated over the eastern outflow regions over the ocean. Over the eastern inland regions of both countries, the O3-CO regression slope is lower than that over the outflow region, reflecting in part continuous O3 production in the outflow region. The simulation result shows that the proportion of contribution from biogenic isoprene to the regressed O3-CO slopes various depending on the corresponding local emission scenario. While biogenic isoprene oxidation makes a comparable contribution as anthropogenic emissions in the eastern US, the latter dominates over eastern China. Over the western inland regions of both countries, the O3-CO regression slope can be higher than the eastern inland regions due to transport from lateral and upper boundaries. The observations of O3-CO regression slope provide the means to understand the relative importance of anthropogenic and biogenic emissions on O3 as well as transport. In addition to O3-CO, strong correlations and consistent linear regression slopes of O3-CH2O and CO-CH2O were also observed during the DISCOVER-AQ aircraft experiment in July 2011 over the Washington-Baltimore area. Same as CO, we also analyze the model results to understand the factors contributing to the observed O3-CH2O regression slope by tracing separately three different CH2O sources: primary secondary anthropogenic sources, biogenic isoprene oxidation, and transport from model… Advisors/Committee Members: Wang, Yuhang (advisor), Deng, Yi (committee member), Ng, Nga Lee (committee member), Weber, Rodney (committee member), Crawford, James (committee member).

▼ Ozone present in the atmosphere not only absorbs the biologically harmful ultraviolet radiation but also is an important ingredient of the climate system. The radiative absorption properties of ozone make it a determining factor in the structure of the atmosphere. Ozone in the troposphere has many negative impacts on humans and other living beings. Another significant aspect is the absorption of outgoing infrared radiation by ozone thus acting as a greenhouse gas. The variability of ozone in the atmosphere involves many interconnections with the incoming and outgoing radiation, temperature circulation etc. Hence ozone forms an important part of chemistry-climate as well as radiative transfer models. This aspect also makes the quantification of ozone more important. The discovery of Antarctic ozone hole and the role of anthropogenic activities in causing it made it possible to plan and implement necessary preventive measures. Continuous monitoring of ozone is also necessary to identify the effect of these preventive steps. The reactions involving the formation and destruction of ozone are influenced significantly by the temperature fluctuations of the atmosphere. On the other hand the variations in ozone can change the temperature structure of the atmosphere. Indian subcontinent is a region having large weather and climate variability which is evident from the large interannual variability of monsoon system over the region. Nearly half of Indian region comprises the tropical region. Most of ozone is formed in the tropical region and transported to higher latitudes. The formation and transport of ozone can be influenced by changes in solar radiation and various atmospheric circulation features. Besides industrial activities and vehicular traffic is more due to its large population. This may give rise to an increase in the production of tropospheric ozone which is greenhouse gas. Hence it becomes necessary to monitor the atmospheric ozone over this region. This study probes into the spatial distribution and temporal evolution of ozone over Indian subcontinent and discusses the contributing atmospheric parameters.

▼ Conventional sources of emissions have been a prime target for policymakers in designing pollution control strategies. However, the evolution of shale gas activities is a growing concern over the impact of unconventional sources on urban and regional air quality. Owing to the development of Barnett Shale production, the fast-growing Dallas-Fort Worth (DFW) metroplex has encountered both types of these emissions. Oil and gas activities result in emissions of ozone precursors, notably volatile organic compounds (VOC). The major objective of this study was to evaluate the spatio-temporal distribution of VOC in order to highlight the influence of unconventional emissions. The study utilized measurements from automated gas chromatography (AutoGC) monitors to analyze the patterns of the total non-methane organic compounds (TNMOC) and relative contributions from marker species of traffic versus oil and gas activities. In this study, data from 2001-2014 was obtained from the Texas Commission on Environmental Quality (TCEQ) for fifteen monitoring sites within the North Texas region. With over a thousand wells in a 10 mile radius, two of the rural sites measured twice as much TNMOC as compared to the urban site in Dallas. Source apportionment analysis was conducted using Positive Matrix Factorization (PMF) technique. The target site located in the urban zone resolved an eight factor model. Natural gas signature was the dominant source of emission with a 52% contribution followed by 31% from two separate traffic-related sources. Considering ethane to be the dominant species in oil and gas emissions, it was observed that the rising ethane/NOx ratio correlated with increasing annual average ozone post-2007. In this period, higher concentration of ozone was found to be associated with stronger winds from the Barnett Shale area – a region that did not seem to contribute to high ozone during 2001-2007. With traffic emissions having flattened over the years, the recent increase in oil- and gas-related emissions has a negative impact on the air quality in this area. Results indicate that the area has failed to observe a declining trend in ozone despite effective reductions in NOx and traffic-related VOC emissions. The findings of the study would be helpful in proper evaluation of the ozone-forming potential of unconventional VOC emissions. Although these emissions may not be strong enough to cause harm through direct exposure, underestimating their potential towards ozone formation could hinder the progress in ozone attainment in growing urban areas. After all, a major portion of the study area continues to be in nonattainment of the EPA designated ozone standards. The study therefore draws the attention of policymakers towards the new influx of emissions that have emerged as a powerful source within the DFW metropolitan area.

▼ Ozone (O3) profiles have been measured with high accuracy and precision by balloon-borne ozonesonde instruments since the 1960s. Since then, global ozonesonde networks have amassed vast data sets, compiling O3 climatologies with which to develop and validate satellite retrieval algorithms, and evaluate chemical transport model output. A typical way to formulate O3 climatologies is to average ozonesonde profiles on a monthly or seasonal basis, either for specific regions or zonally. Shortcomings of this simplistic averaging are quantified in this dissertation through use of a statistical clustering technique, self-organizing maps (SOM). First, the SOM algorithm and its application to ozonesonde profiles are detailed. Sensitivity tests comparing SOM with the similar k-means algorithm lead to the decision to employ SOM to ozonesonde data sets, and justified the choice of a 3x3 SOM with nine clusters. SOM is then applied to >4500 ozonesonde profiles from the long-term U.S. monitoring sites Boulder, CO; Huntsville, AL; Trinidad Head, CA; and Wallops Island, VA. The clusters of surface – 12 km amsl O3 mixing ratio data are closely linked to large-scale meteorological conditions. At all four sites, profiles in SOM clusters exhibit similar tropopause height, 500 hPa height and temperature, and total and tropospheric column O3. When profiles from each SOM cluster are compared to monthly O3 means, near-tropopause O3 in three of the clusters is double (over +100 ppbv) the climatological O3 mixing ratio. The three clusters include 13–16% of all profiles, mostly from winter and spring. Large mid-tropospheric deviations from monthly means (-6 ppbv, +7 – 10 ppbv O3 at 6 km) are found in two highly-populated clusters with a combined 36–39% of profiles. The latter clusters represent both distinctly polluted (summer) and clean O3 (fall-winter, high tropopause) profiles. Finally, we explore the capability of SOM clusters to identify high surface O3 events. Clusters of O3 profile data over a narrowed altitude range (surface – 6 km amsl) from Trinidad Head, CA, are linked to surface O3 monitor data at inland locations in CA. SOM clusters of O3 profile data from the lower troposphere can discriminate background vs polluted O3 and the conditions linked with each. Two of nine O3 clusters exhibit thin layers (~100s of m thick) of high O3, typically between 1 and 4 km, and residing above a subsidence inversion associated with a northern location of the semi-permanent Pacific subtropical high. Ozone in these clusters is upwind of high-altitude surface O3 monitors at inland locations. The surface O3 monitors at Lassen Volcanic and Yosemite National Parks, and Truckee, CA, display a marked impact of the elevated tropospheric O¬¬3. Days corresponding to the high O3 clusters exhibit hourly surface O3 anomalies at these sites of +5–10 ppbv compared to a climatology; the anomalies can last up to four days.

▼ Tropospheric ozone climatology over equatorial and southern Africa has been at the core of this study. SHADOZ (Southern Hemisphere ADditional OZonesondes) network data for the period 1998-2013, from Irene (South Africa) and Nairobi (Kenya), and MOZAIC (Measurement of OZone and water vapor by Airbus In service air Craft) programme data for the period 1998-2001 from Brazzaville (Congo) respectively have been used to investigate tropospheric ozone characteristics with regard to climate change parameters. These locations, which represent three different African climate zones including tropical (Brazzaville), equatorial (Nairobi) and subtropical (Irene) are poorly documented with regard to the variation and distribution of tropospheric ozone, although its levels over the region have been increasing since the last two decades of the twentieth century. With recent changes observed on climate parameters due to climate change, tropospheric ozone distribution and variability over this region have been investigated. Climate parameters including air temperature and relative humidity and ozone parameters such as partial pressure have been used to achieve the objective of this study. Results from tropospheric ozone modeling at Irene, using long term ozonesonde data from SHADOZ network, confirm the seasonal patterns of ozone, such as previously observed over southern Africa, with two maxima occurring in summer and spring respectively. However, increase on ozone concentrations from 55 to 65.6 DU in spring and from 32 to 55 DU in summer has been noted, in comparison with previous short term studies undertaken at this location. In the Congo Basin tropospheric ozone climatology investigated using short term aircraft data from MOZAIC programme collected at Brazzaville for the period 1998-2001 also presents two seasonal maxima occurring in August and February with 35.4 DU and 26.1 DU respectively. Over equatorial eastern Africa, which presents one of the most complex meteorogical system in the African continent, seasonal ozone distribution has also been noted with two peaks (43.0 DU) and (46.8 DU) occurring in July and October respectively. Analysis of case studies using HYSPLIT_4 (Hybrid Single-Particle Lagrangian Integrated Trajectory version 4) model and NCEP/NCAR (National Centers for Environmental Prediction/National Center for Atmospheric Research) reanalysis model has shown that increase on tropospheric ozone over these regions is determined by precursor from both local and long range transport based from remote sources (biomass burning, lightning and biogenic emissions). The role played by dynamic processes is defined by positive divergence values and negative flux on zonal and meridional wind patterns prevailing at upper troposphere due to a quasi-permanent low pressure system prevailing in the region which in turn implies the highest partial ozone value observed in this region.

▼ It has been shown by Schlesinger and Mintz (1979) that the UCLA general circulation model (GCM) is able to simulate the observed negative correlation between the total amount of ozone in a vertical atmospheric column (the total ozone) and the eastward-propagating synoptic disturbances in the troposphere, with the total ozone maxima and minima located respectively at the troughs and ridges of the tropospheric waves. The goal of the present study was to understand how the GCM simulated this observed relationship. Our analysis shows that the transient-eddy total ozone disturbances were an omnipresent feature of the GCM January simulation in the northern hemisphere midlatitudes, just as they are in nature. It is also found that the transient-eddy total ozone disturbances in the northern hemisphere midlatitudes were closely related to the transient-eddy geopotential heights there throughout the entirety of the simulation. Furthermore, the correlations between these two quantities are negative up to the 72 mb level and attain their largest negative values at the 300 mb level. The analysis also shows that the transient-eddy disturbances in the stratosphere are out of phase with their counterparts in the troposphere, in accord with what would be expected from Dines compensation. In the GCM simulation there is a well-defined positive correlation between the total ozone and the ozone content in each of the model layers in the upper troposphere and lower and middle stratosphere. It is found that although layers 5-8 (19.3-150 mb) contain the largest percentage of the total ozone, it is predominantly layers 6-9 (37.3 -300 mb) that make the largest contribution to the temporal variations of total ozone. In accordance with the observations, a strong negative correlation is found between the simulated total ozone and the height of the simulated tropopause. However, changing the height of the tropopause cannot in itself change the total ozone, but rather only its partitioning between the stratosphere and the troposphere. Our analysis clearly shows that it is the ozone convergence and divergence in an atmospheric column, not the photochemical ozone production and destruction, which are responsible for the synoptic increases and decreases of total ozone.
