FWA is to provide support for and further development of GFAS, which is operated at ECMWF. GFAS delivers near-real-time emissions of gases and aerosols from biomass burning through data assimilation of multi-satellite FRP retrievals supporting atmospheric composition forecasts. The Contractor will provide improvements for the current GFAS system in terms of evaluation and improvement of injection height estimation, provide near-real-time Fire Radiative Power (FRP) observations from the GOES and Himawari geostationary satellites, evaluate and refine the merging of GEO and LEO satellite FRP products including the introduction of new products, provide and implement recommendations for service evolution, update information on spurious FRP signals, as well as deliver memoranda and reports.
