"The Tropospheric Ozone Pollution Project (TOPP):  O3 and SO2 Sondes from 2004 - 2012"

Prof. Gary Morris, Department of Physics & Astronomy and Associate Dean of the College of Arts & Sciences, Valparaiso University

In this talk, Dr. Morris reviews his Air Quality research through an overview of the the Tropospheric Ozone Pollution Project (TOPP).  Since its inception in 2004, TOPP has been continuously funded and flown ~600 specially instrumented balloon payloads to measure ozone, sulfur dioxide, wind speed and direction, temperature, humidity, and pressure at numerous sites around the world, with more than 50 students having had the chance to work on the project.  Some findings we explore are the view from space, the role of ozone in the atmosphere, the impact of forest fires on air quality, the influence of lightning on ozone, and the emission of SO2 plumes from volcanoes and human activities.
