Understanding Topography and Near-shore Gradients in Ozone at the Lake Michigan Shoreline

Abstract

Surface ozone is generated by photochemical production in a stable atmosphere which can be affected by a multitude of factors. We are looking at the correlation between topography, lake breeze extent and ozone gradients in the shoreline environment of Lake Michigan. Typically, the high ozone events in shoreline areas of Lake Michigan are due to the shallow marine inversion layer containing higher ozone concentrations. Currently, I am working on getting geospatial and monitoring data from the WiDNR and historic data from mobile measurements during the Lake Michigan Ozone Study 2017. Then, I will explore if there is a relationship between the topography of the areas of steep shoreline gradients in ozone.
