IMPORTANCE: On August 2, 2012, high tropospheric ozone levels, above the EPA limit of 75 parts per billion by mass, were forecast for Wichita, Kansas. Trajectories for ozone transport were examined using two software packages: McIDAS and HYSPLIT. The source of the rise of ozone concentration was examined, namely whether it came from the stratosphere or was a buildup from the ground level. Evidence of stratosphere ozone was lacking. OBJECTIVE: The reason for this research is to investigate the source of high concentrations of ozone in the troposphere. One possibility is the entrance of stratospheric ozone via tropopause folding. Another possible source of high ozone concentration comes from photochemistry in the troposphere, possibly around Wichita or upstream of Wichita. However, the photochemistry details are not part of this study. Instead, the study concerns itself with transportation of ozone pollution to Wichita of either tropospheric ozone produced elsewhere or ozone precursors. METHODS: We use the McIDAS software to analyze the data we collected from the NCAR datasets and use the information to analyze the presence of stratospheric ozone and the ozone concentration in Wichita due to the impact of tropopause folding. Also, we applied the HYSPLIT model to investigate where the polluted air was. The map area is attempting to describe the source and movement of ozone, impacting human health. Therefore, the HYSPLIT trajectory analyzes the ozone movement from August 2, 2012, and August 4, 2012, to determine the wind direction. RESULT: During the period, the NCAR (National Center for Atmospheric Research) dataset was collected, and the ozone mixing ratio at 500 hPa and 850 hPa was run. The 500 hPa map and 850 hPa* map in figure 3 and figure 4, respectively, show the ozone values that are relatively high across the same region. The NCAR data result at 850 hPa* and 500 hPa agreed with the forecast of August 2, 2012, that the tropospheric ozone concentration was high. However, the stratosphere ozone cannot be established during this day because the HYSPLIT trajectory model suggested no wind migrating from the Rocky Mountains to Wichita, Kansas. The investigation reviewed that the data from the Cfsrr in the Cfsr (Climate Forecast System Reanalysis) was the framework for this study. It indicates the increased ozone concentration in the troposphere and shows that ozone expels from the stratosphere to the troposphere cannot be established. The 3-D grid model is used to analyze the data, and the color indicates the increase of ozone. Furthermore, the tongue-like structure suggests the presence of tropopause presence in the Rocky Mountains. CONCLUSIONS: There was no stratospheric ozone because the wind direction was not coming from the Rocky Mountains; instead, we saw the trajectory coming from Texas and local wind-generated within Kansas, Oklahoma, Arkansas, and Missouri. However, that part of the ozone transported from Texas, Arkansas, Missouri, and Oklahoma might have escalated the ozone concentration above 75ppb (part per billion).

The main goal of our work was to provide in situ water vapor and ozone profiles in the upper troposphere and lower stratosphere as reference measurements for the validation of SAGE III water vapor and ozone retrievals. We used the NOAA/CMDL frost point hygrometer and ECC ozone sondes on small research balloons to provide continuous profiles between the surface and the mid stratosphere. The NOAA/CMDL frost point hygrometer is currently the only lightweight balloon borne instrument capable of measuring water vapor between the lower troposphere and middle stratosphere. The validation measurements were based in the arctic region of Scandinavia for northern hemisphere observations and in New Zealand for southern hemisphere observations and timed to coincide with overpasses of the SAGE III instrument. In addition to SAGE III validation we also tried to coordinate launches with other instruments and studied dehydration and transport processes in the Arctic stratospheric vortex.

The stratospheric ozone is important for the protection of the biosphere from the dangerous ultraviolet radiation of the sun, forms the temperature and dynamical structure of the stratosphere, and, therefore, has a direct influence on the general circulation and the surface climate. The tropospheric ozone can damage the biosphere, impact human health, and plays a role as a powerful greenhouse gas. That is why the understanding of the past and future evolution of the ozone in different atmospheric layers, as well as its influence on surface UV radiation doses, and human health is important. The problems of preventing further destruction of the ozone layer, the restoration of the ozone shield in the future, and air quality remain important for society. The interest in these problems was recently enhanced by the unexpected discovery of a negative ozone trend in the lower stratosphere and the appearance of a large ozone hole over the Arctic in spring 2020. This book includes papers describing several aspects of the ozone layer’s state and evolution based on the recent experimental, statistical, and modeling works. The book will be useful for readers, scientists, and students interested in environmental science.
