Near real time global biomass burning emissions product from geostationary satellite constellation
- Global fire radiative power is obtained from multiple geostationary satellites
- Diurnal FRP patterns for individual fire pixels are simulated
- Global biomass burning emissions are produced in near real time from FRP
Near real time estimates of biomass burning emissions are crucial for air quality monitoring and forecasting. We present here the first near real time Global Biomass Burning Emission Product from Geostationary satellites (GBBEP-Geo) produced from satellite-derived Fire Radiative Power (FRP) for individual fire pixels. The FRP is retrieved using WF_ABBA V65 (Wildfire Automated Biomass Burning Algorithm) from a network of multiple geostationary satellites. Because of the impacts from sensor saturation, cloud cover, and background surface, the FRP values are generally not continuously observed. The missing observations are simulated by combining the available instantaneous FRP observations within a day and a set of representative climatologic diurnal patterns of FRP for various ecosystems. Finally, the simulated diurnal variation in FRP is applied to quantify biomass combustion and emissions in individual fire pixels with a latency of one day. By analyzing global patterns in hourly biomass burning emissions in 2010, we find that peak fire season varied greatly and that annual wildfires burned 1.33×10^12 kg dry mass, released 1.27×10^10 kg of PM2.5 and 1.18×10^11 kg of CO globally (excluding most part of boreal Asia, Middle East and India because of no coverage from geostationary satellites). Evaluation of emission result reveals that the GBBEP-Geo estimates are comparable with other FRP-derived estimates in Africa and with the values modeled from burned area and fuel loading over the United States.
