Biomass burning significantly affects air quality and climate changes. Current estimates of burning emissions
are rather imprecise and vary markedly with different methodologies. This paper investigates biomass burning
consumption and emissions using GOES (Geostationary Operational Environmental Satellites) WF_ABBA
(Wildfire Automated Biomass Burning Algorithm) fire product. In doing this, we establish a set of representatives
in diurnal patterns of half-hourly GOES Fire Radiative Power (FRP) for various ecosystems. The representative
patterns are used to fill the missed and poor observations of half hourly FRP in GOES fire data for individual fire
pixels. The simulated FRP is directly applied to the calculation of the biomass combusted during fire activities.
The FRP-based biomass combustion is evaluated using the estimates using a traditional model which
integrates burned area, fuel loading, and combustion factor. In the traditional model calculation, we derive
burned areas from GOES WF_ABBA fire size. Fuel loading includes three different types (1) MODIS Vegetation
Property-based Fuel System (MVPFS), (2) National Dangerous Rating Systems (NFDRS), and (3) the Fuel
Characteristic Classification System (FCCS). By comparing the biomass combustions across the Contiguous
United States (CONUS) from 2003-2005, we conclude that FRP is an effective tool to estimate the biomass
burning emissions. Finally, we examine the temporal and spatial patterns in biomass combustions and
emissions (PM2.5, CO, NH3) across the CONUS.
