The latest daily Fire Radiative Power (FRP) analysis from GFAS is available here. The map represents the thermal radiation measured from space-borne sensors and detected as coming from actively burning vegetation and other open fires. It is expressed as the daily average of the fire radiative power (FRP) observations made in 125 km grid cells and expressed in the units of [mW/m²]. The rate of release of thermal radiation by a fire is believed to be related to the rate at which fuel is being consumed and smoke produced. Therefore, these daily averaged FRP areal intensity data are used in the global estimation of open vegetation fire trace gas and particulate emissions. 

Archived Fire Radiative Power maps (global and by selected areas) are available here for the past 5 days.

Known issues

• 31 March - 17 April 2022: No Aqua MODIS FRP data due to known issues with the satellite.
• 22 February 2021: Aqua and Terra MODIS FRP data changed from collection 6 to collection 6.1
• 18 November 2020: Aqua MODIS FRP data reintroduced to GFAS processing
• 19 August 2020: No Aqua MODIS FRP data available since 17 August (limited coverage on 16th) due to known issue with the satellite as documented at https://ladsweb.modaps.eosdis.nasa.gov/alerts-and-issues/?id=44995.
• 3 July 2018: GFAS production moved to ECMWF operations; standard output updated to include altitude of plume bottom and injection height from IS4FIRES.
• 23-27 June 2018: Limited MODIS FRP observations being used in daily NRT GFAS processing.
• 19 December 2016: Aqua and Terra MODIS FRP data changed from collection 5 to collection 6.
• 8-9 August 2016: no Aqua MODIS data available leading to reduced GFAS emissions over Africa and South America - all other regions seem to be unaffected.
• 22 April 2016: Terra MODIS data reintroduced to GFAS processing.
• 1 March 2016: Terra MODIS removed from GFAS processing.
• 24 February - 4 March 2016: anomalous FRP values associated with degraded Terra MODIS data being used in GFAS.
  • Updated 20 September 2016: GFAS FRP values for these dates have been recalculated using Aqua MODIS data only and have replaced the anomalous values in the GFAS catalogue. For users that have downloaded the GFAS data for these dates, we recommend to download them again.
