Over Water and Shoreline Observations at Lake Michigan Using UAS and DOAS During AGES+ 2023

Abstract

Residents on the shoreline of Lake Michigan in southwest Wisconsin are subject to air quality issues from high ozone concentrations near ground level. Meteorological data was collected for the August 2023 AGES+ campaign concerning ozone concentration, temperature, wind speed, and wind direction. Measurements were conducted using a DJI M300, with two IMETs and POM sensors attached, with flights occurring over Lake Michigan near the Chiwaukee Prairie area. Results were then correlated with the Wisconsin DNR’s ground station in Chiwaukee Prairie, which found moderate correlation of data between measurements conducted above water and on land.
