This thesis presents a study of several meteorological factors and their correlation to tropospheric ozone concentrations in Ypsilanti, Michigan. The meteorological factors studied were air pressure, absolute humidity, temperature, and wind speed and direction. Data was collected from the end of May 2019 to the end of August 2019, on the second story of the Sherzer building at Eastern Michigan University. This thesis also contains a case study, comparing data from Ypsilanti, Michigan to Nanjing, China, to further strengthen the significance of the results found. The study found that the most significant meteorological determinants to tropospheric ozone concentration at Eastern Michigan University were temperature and humidity (R2 = 0.90 and 0.65, respectively). The influence of each meteorological factor, regardless of significance, was also discussed.
