The FRPPIXEL product records information on the location, timing and fire radiative power (FRP, in MWatts) output of landscape fires ("wildfires") detected every 15 minutes across the full Meteosat disk at the native spatial resolution of the SEVIRI sensor. It has been demonstrated in small-scale experimental fires that the amount of radiant heat liberated in a fire per unit time (i.e. the Fire Radiative Power) is well related to the rate at which fuel is being consumed . This is a direct result of the combustion process, whereby carbon-based fuel is oxidised to CO2 (and other gaseous and particulate products) with the accompanying release of a certain "heat yield". Measuring this FRP and integrating it over the lifetime of a fire 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. 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.

Example Python code to read the product:
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 15-min Fire Radiative Power (FRPPixel) for the period 2004-2015.
This Data Record was obtained with the best version of its equivalent NRT product (FRPPixel) which can also complement the time series from 2016 onwards.
