GMAO Science Snapshot: Sub-city Scale Hourly Air Quality Forecasting by Combining Models with Observations

To better understand air quality risks and mitigate impacts, Global Modeling and Assimilation Office (GMAO) scientists propose a method incorporating outputs of NASA’s GEOS Composition Forecasting (GEOS-CF) model system with satellite information from ESA’s TROPOspheric Monitoring Instrument (TROPOMI) and ground measurement data from the EPA network in the continental United States. GEOS-CF runs at the NASA Center for Climate Simulation (NCCS).
