The FRPGRID product records information on the location, timing and fire radiative power (FRP, in MWatts) output of landscape fires ("wildfires") detected across the full Meteosat disk. It is based upon the FRPPIXEL product produced by the LSA SAF every 15 minutes from SEVIRI at the sensors native spatial resolution, but beyond the detected FRP stored in the FRPPIXEL product the FRPGRID product additionally includes adjustment of the recorded FRP for the influence of cloud cover that can mask fires from view, and for the estimated impact of undetected "low FRP" fires that remain below SEVIRI's active fire detection threshold. Either of these adjustments can be removed from the data if the user wishes, and the full FRPGRID product contents are described in the Supplement to Reference [1]. The product is produced on a 5 degree grid, every hour - which is much coarser than the original FRPPIXEL product input files in order to be able to have the aforementioned adjustments appropriately applied. Measuring the FRP of a fire and integrating it over the fires lifetime provides an estimate of the total Fire Radiative Energy (FRE) released, which for landscape fires should be proportional to the total amount of biomass burned [3]. The FRP approach therefore provides an alternative approach to calculating wildfire fuel consumption through methods that rely on the mapping of burned area and assuming, measuring or modelling the supposed fuel consumption per unit area. It is the basis of the global fire emissions service (GFAS) used within the Copernicus Atmosphere Monitoring Service. Please see the FRPPIXEL product description for more details.

The use of LSA SAF products in publications is kindly requested to be duly acknowledged:
FRPGRID was provided by the EUMETSAT Satellite Application Facility on Land Surface Analysis (LSA SAF; Trigo et al., 2011)

It is also requested that users cite the References below to describe the FRPGrid product if it is used within their studies.

The MSG mission (in operations since 2004) already provides a relatively long time series of VIS and IR observations over the full Earth Disk centred at 0º. The full archive of MSG/SEVIRI data was reprocessed to provide the user comunity a consistent, homogeneous and continuous Data Record of the hourly Fire Radiative Power Gridded (FRPGrid) for the period 2004-2015. 

This Data Record was obtained with the best version of its equivalent NRT product (FRPGrid) which can also complement the time series from 2016 onwards.
