GFAS-CLIM "Global Fire Assimilation System development for climate applications"

The methodology of the MODIS-FRP-based Global Fire Assimilation System (GFAS, Kaiser et al. Biogeosciences 2012) is successfully being used for climate monitoring in NOAA’s annual State of the Climate reports since 2010, despite being originally developed for near-real-time (NRT) smoke emission calculation in the Copernicus Atmosphere Monitoring Service (CAMS). Furthermore, GFAS is currently the only Climate Data Record (CDR) for fire disturbance in the CORE-CLIMAX CDR capacity assessment report.

The assessment finds that GFAS has strongly varying maturity levels from research grade to full operational capability.

This BMWi-funded project develops a new version of GFAS, named GFAS-CLIM, that is specifically adapted for climate applications in three respects. It will:

  • reach at least initial operational capability in all criteria of the CORE-CLIMAXmaturity matrix; this addresses mostly software engineering and documentation,
  • implement a Kalman smoother as alternative to the Kalman filter; this data assimilation method that can be exploited only in retrospective analyses,
  • assimilate FRP observations from the Sentinel-3 satellites as provided by the ESA Fire CCI.

The project closely coordinates its activities with those in CAMS and Fire CCI. The new CDR will be documented in the scientific literature and be made publicly available on the ECCAD server of the IGBP GEIA initiative.
