2 FRP Products [NRT Operational] 2

3 Operational SEVIRI FRP_PixelProduct Europe N. Africa Global product generated from FRP pixel derived for different dates only as a visual example South America S. Africa 4 Processing Regions Available via FTP/EUMETCast from the EUMETSAT Land Surface Analysis Satellite Application Facility (LSA SAF) - for data, ATBD, Product User Manual & Validation Report FRP Pixel Product (native spatial/temporal resolution) available within 3 mins FRP Gridded product - inc. adjustments for small fires and clouds also available.

5 GOES FRP Product (America s) July 27 N. America GOES W GOES E S. America Available on request in NRT from KCL now (users ECMWF and Met Office Currently) End of next year should be available from LSA SAF

6 Expected Global Geostationary System Meteosat: Operational via LSA SAF GOES-E: Future operational currently KCL but available to users GOES-W: Future operational currently KCL but available to users FY2: Future CMA currently KCL Non-Optimum 3.9 µm channel data quality MTSAT: Maybe future operational currently KCL Non-Optimum 3.9 µm channel dynamic range + Meteosat Third Generation (217+) will have: improved temporal resolution 2 km spatial resolution(ssp) widerange3.9µmband.

DME globally GFED3.1 notably higher in the boreal belt and in the tropics Global Mean Ratio:.81 CF GFED3.1/GFAS1. [g kj -1 ] CF W :.368 g kj -1 GFAS1. higher in NH temperate regions GFAS1. greater spatial extent of areas affected by fire

Frequent Fires in Croplands or Savannah FRE [kj m -2 year -1 ] N monthly fire observations [months] 33% of grid cells with GFAS1. fire observations not detected by GFED3.1: - typically low fuel consumption (< 2.7 kj m -2 year -1 ) - repeated small fires in savanna, deforestation and agricultural areas - contribute < 3% to global FRE Only.1% of grid cells with GFED3.1 fire observations not detected by GFAS1. 1% 5% 36% EF DF 39% SA 9% 1% AG
