Characterization and Application of JPSS Products in Biomass Burning Studies

We aim to characterize Joint Polar Satellite System (JPSS) trace gas and aerosol products with observations from aircraft field campaigns. These JPSS data in turn provide opportunities to improve the understanding of biomass burning emissions in atmospheric chemical-transport models. Aircraft observations from the NASA ATom and NOAA/NASA FIREX-AQ field campaigns provide objective comparisons for the NOAA Unique Combined Atmospheric Processing System (NUCAPS) trace gas retrievals of the infrared (CrIS) and microwave (ATMS) instruments and Visible Infrared Imaging Radiometer Suite (VIIRS) aerosol retrievals onboard the Suomi National Polar-orbiting Partnership (S-NPP) and NOAA-20 satellites. NUCAPS carbon monoxide (CO) and VIIRS aerosol optical depth (AOD) retrievals improved through these comparisons to in-situ aircraft observations subsequently serve as input to an assimilation system based on NOAA’s FV3-Chem global forecasting model. A goal of these assimilation experiments is the improvement of biomass burning emission source treatments.
