UWEC CERCA 2025

Air quality is of concern to the communities along Lake Michigan’s shores in easternWisconsin. In the troposphere oxides of nitrogen, like NO2, react with volatile organic compounds, like formaldehyde, to form ozone,which is a harmful pollutant to human health. Lake Michigan traps these harmful chemicals in the troposphere, which results in ahigher-than-normal amount of ozone in these communities’ air. During the summer of 2023 in Kenosha, WI, the OPSIS DOASinstrument was placed on the Kenosha Municipal Building and the water treatment plant and took measurements of O3, NO2 and SO2 during the months of July and August. During this time, the AGES+ field campaign was also taking place, where ground, satellite, and aircraft observations were targeted around the Chicago, New York and Toronto regions. This data has been uploaded a repository that is part of the field campaign, AGES+. My poster will display the OPSIS DOAS data from the Kenosha, Wisconsin and data gathered from overwater aircraft sampling by University of Alabama Huntsville and perform an analysis to determine data correlations and find possible trends.
