GFAS version 1.2

GFAS data includes: Fire Radiative Power (FRP), dry matter burnt and biomass burning emissions.

Data are available at global horizontal resolution of 0.1 degrees from 2003 to present. The features of the current version of GFAS are:

Injection height daily data (Mean altitude of maximum injection and Altitude of plume top) as provided by a Plume Rise Model
Pixel based quality control for MODIS/Aqua and Terra and SEVIRI observations
Statistical regression of the output when assimilating only Aqua or Terra observations so as to preserve consistency with data obtained assimilating Aqua and Terra observations

The gridded FRP products are also available hourly (e.g. gridded Aqua FRP from 1 to 2 UTC). Those may be browsed through the GFAS catalogue and then retrieved via Web-API.

GFAS Data Access

Before downloading data, users must accept the Copernicus CAMS data licence

Then access to the archive is either:

via the web using the ECMWF data server web interface:http://apps.ecmwf.int/datasets/data/cams-gfas/
or through WebAPI, which is the method allowing users to download CAMS data in a programmatic way (using Python - example scripts are available).

GFAS Maps

The latest daily Fire Radiative Power (FRP) analysis from GFAS is available here

Archived Fire Radiative Power maps (global and by selected areas) are available here.

Known issues

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.
