Minimize FRP Processing

The Fire Radiative Power (FRP) processing module is an independent processor starting from SLSTR L1b products.

The first step is the common processing described in the Derivation Pixel-by-Pixel Module. This step enables in particular the projection of SWIR measurements on the 1 km grid.

 

Then the FRP processing is divided into 3 steps:

  • A global fire detection step: based on spatial and spectral thresholding tests, pixels potentially associated to a fire are identified;
  • A fire confirmation step: for each fire pixel selected in the previous step, the actual presence of a fire is confirmed using statistical information regarding the background window and comparing these numbers to the potential fire.
  • A fire characterization step: when a fire is confirmed, a series of fire properties are calculated such as FRP, uncertainty, confidence, classification ....

The FRP processing uses two types of radiometric measurements:

  • S7 and F1 thermal channels mainly for land fires
  • S6 SWIR channel mainly for detecting gas flares
