Overview
The Global Fire Assimilation System (GFAS) assimilates fire radiative power (FRP) observations from satellite-based sensors to produce daily estimates of biomass burning emissions. It has been extended to include information about injection heights derived from fire observations and meteorological information from the operational weather forecasts of ECMWF.
GFAS data includes: Fire Radiative Power (FRP), dry matter burnt and biomass burning emissions.
Data are available globally on a regular lat-lon grid with horizontal resolution of 0.1 degrees from 2003 to present. The features of the current version of GFAS (GFAS v1.2) are:
- Injection height daily data (Mean altitude of maximum injection and Altitude of plume top) as provided by a Plume Rise Model
- Pixel based quality control for MODIS/Aqua and Terra and SEVIRI observations
- Statistical regression of the output when assimilating only Aqua or Terra observations so as to preserve consistency with data obtained assimilating Aqua and Terra observations
Information about previous versions of GFAS is also available.
The gridded satellite data (stream=gfas, type=gsd) are also available hourly (e.g. gridded Aqua FRP from 1 to 2 UTC). Those may be browsed through the GFAS catalogue and then retrieved via Web-API.
