Linking satellite data with air quality

Room 811 AOSS, January 25, 2017, 2:30 PM

Abstract

As satellites advance in their ability to detect ambient concentrations of gases and aerosols, these eyes in the sky bear increasing relevance to near-surface atmospheric chemistry and air quality assessment. Nitrogen dioxide (NO2) is the satellite-derived constituent with the most direct connection to fossil fuel emissions. At present the Ozone Monitoring Instrument aboard the NASA Aura satellite offers the highest resolution NO2 retrievals, and new missions under development (TropOMI, TEMPO, GEMS, Sentinel-4) offer the potential for improved data in coming years. This talk will present results applying satellite-derived NO2 and related species to characterize air quality and emissions in the U.S. Talk will include a discussion on the role of science outreach to ensure the relevance of research to stakeholder communities.
