Near-Real Time Global Biomass Burning Emissions Product from Multiple Geostationary Satellites

摘要

Near-real time estimates of biomass burning emissions are important for air quality monitoring and forecasting. We present here the preliminary analysis of global biomass burning emission product (GBBEP) produced from geostationary-satellite-derived fire radiative power (FRP) in near-real time. Specifically, the FRP is retrieved at an interval of 15 to 30 minutes using WF_ABBA_V65 (Wildfire Automated Biomass Burning Algorithm) from multiple geostationary satellites. The missing FRP detections are simulated by combining the available instantaneous FRP observations within a day and the representative ecosystem-dependent climatologic diurnal pattern of half-hourly FRPs. Finally, the diurnal variation in FRP is applied to quantify global emissions of PM2.5 (particulate mass for particles with diameter < 2.5 μm) and trace gases with a one-day latency. The algorithm is tested by analyzing global patterns in hourly biomass burning emissions for 2010.
