Brief Bio

Thompson’s research interests include tropospheric chemical and dynamical processes, from air-sea gas exchange to interactions with the lower stratosphere. Her work in the 1980s and early 1990s was among the first to link chemical changes, climate forcings and the earth’s oxidizing capacity. Trends of atmospheric ozone and the interaction of natural variability and human influence (biomass fires, urban pollution) are on-going themes of research that employs satellite data from a variety of sensors. A veteran of a dozens of NASA aircraft missions, ground-based campaigns and oceanographic cruises, Thompson was Co-Mission Scientist for SONEX (1997) and is PI for the SHADOZ (Southern Hemisphere Additional Ozonesondes) tropical validation network. Thompson's recent activities include membership in NASA's Health and Air Quality Science Team and Co-I on an Interagency Agreement with Dept of Interior's BOEM to apply satellite data to monitoring pollution from Gulf of Mexico Oil and gas operations. A member of Goddard’s Laboratory for Atmosphere for 20 years, Thompson was a Professor of Meteorology at Penn State for 8 years before re-joining GSFC in 2013. Community contributions have included membership on AMS and AGU Councils and past President of the International Commission on Atmospheric Chemistry and Atmospheric Chemistry and the AGU Atmospheric Sciences Section.  Thompson's honors include the AMS Verner Suomi Award, the AGU Reger Revelle Medal, Corresponding Member of the Academy of Athens. She received Goddard’s William Nordberg Memorial Award for Earth Sciences in 2018 for “fundamental contributions to the understanding of the interactions between tropospheric composition and climate.”
