As an incoming freshman, I spent the summer working in the Department of Atmospheric Science at the UW. Dr. Jaffe’s group tracked airborne pollutants arriving in the US via high-altitude winds over a period of years using airplanes and ground-based stations. It was my duty to determine if a small, light ozone sensor was suitable for our aircraft platform. I collected experimental data from the small Cessna research airplane and concluded that the new instrument obtained more consistent data than the control instrument. Although this involved extensive data analysis on my part, I learned many helpful tools in processing large amounts raw data into usable conclusions.
