Assistant Professor Jeffrey Geddes has published “Stratosphere-troposphere separation of nitrogen dioxide columns from the TEMPO geostationary satellite instrument” in Atmospheric Measurement Techniques. “Separating the stratospheric and tropospheric contributions in satellite retrievals of atmospheric NO2 column abundance is a crucial step in the interpretation and application of the satellite observation,” Geddes and his colleagues write. Their developments include “using independent satellite observations to identify likely locations of tropospheric enhancements, using independent LEO observations for spatial context, consideration of diurnally varying partial fields of regard, and a filter based on stratospheric to tropospheric air mass factor ratios.”
