Communities surrounding Lake Michigan suffer from poor air quality due to the proximity to major emissions from the Milwaukee-Chicago-Gary urban corridor and unique meteorological effect of trapping those pollutants in thermal inversions over Lake Michigan. Ozone, a key component of photochemical smog, is produced when urban emissions remain in stagnant air in sunlit conditions and shoreline communities in Eastern Wisconsin are in non-attainment of federal ozone standards. The WiscoDISCO-22 field campaign was conducted in Chiwaukee Prairie, WI in Kenosha County, where a regulatory monitor is located. This site often sees the highest ozone concentrations in Wisconsin. This field campaign studied the lower atmosphere by using Unmanned Aerial Systems to measure ozone, temperature, humidity and pressure. The UAS flight logs can also be used to derive winds from UAS platforms. The study incorporated flying two UAS: one overland and one overwater, to investigate the vertical profile of pollutants and vertical mixing of air parcels at this location. Analysis of these vertical profiles will be presented.
