Air Quality Remote Sensing Program
Emissions Products

Emissions from both natural and anthropogenic sources contribute to poor air quality. Biomass burning (prescribed and wild fires) release huge amounts of smoke (primary particulates dominated by black carbon) and trace gases into the atmosphere. Power plants, oil refineries, and other industrial sources release emissions NO2 (nitrogen dioxide), H2CO (formaldehyde), SO2 (sulfur dioxide), and other organic compounds leading to poor air quality as well. The EPA compiles National Emissions Inventory (NEI) every year for a number of critical environmental management and policy activities such as tracking the Clean Air Act and Clean Air Interstate Rule. Emissions data are used to determine trends over time as well as to initialize air quality forecast models. One of the primary sources of uncertainty in air quality forecasts comes from the uncertainties in these emissions. NESDIS / STAR developed algorithms to derive emissions of PM2.5 and trace gases from biomass burning. These products will be provided to NWS in near real time for assimilation into air quality forecasting models.
