- via the web (for sample data, limited to one month) 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 an operational programmatic way (using Python - example scripts are available).

Expand title Latest seven days of GFAS data are also available through the FTP Dissemination server. Note that for the convenience of users who cannot use the ECMWF data server (either via the interactive web interface or through the ECMWF WebAPI), the latest seven days of GFAS data are also available through the FTP Dissemination server. On the FTP server, the new GFAS data becomes available with several hours delay compared to the ECMWF data server. If you wish to have an FTP account setup, please contact Copernicus User Support at ECMWF.
EXAMPLE describing explicitly what is in the files and how the data is described in file headers of GFAS data files on the FTP server.

GFAS data file name and file format
GFAS File format is GRIB. See What are GRIB files and How to read or decode a GRIB file for more information.
GFAS Maps
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.
