The ECMWF FTP service provides access to real-time data from the CAMS Global Fire Assimilation System (GFAS). The description of GFASv1.2 can be found here . For other data access options please see here.

Please see see the list of available variables below and make sure your variables of interest are available.

User accounts

To get access to CAMS GFAS data, you need user accounts on the ECMWF website, and on the ECMWF FTP service.

  1. Log on to (If you do not have an account create one)
  2. Read the CAMS data licence and accept the license at the bottom of the page.
  3. Send an email to, providing
    1. the user name you used to log into and accept the license
    2. for our service planning, a brief description of how you intend to use the data

Retention policy

Data is kept for 7 days

File naming convention

The file naming convention is based on WMO guidelines as follows:



ecmfis the WMO location indicators. The list can be found here.
yyyymmddhhmmssis the base date and time of the forecast.
vvvvis a version or experiment identifier. gfas is used for GFAS products, prod will be used for operational products, test (or experiment ID) will be used for testing purposes, rean for reanalysis if needed.
tttype of data, fc - forecast, an - analysis
ltis the type of level. pl for pressure level products, sfc for surface fields, ml for model level fields
sssis the forecast hour time step. For accumulation and averages, it is the end time. This number must be zero padded to 3 digits, e.g. step 24 is given as 024

is the parameter short name as defined here

grib, nc

is the format of a file, GRIB or NETCDF

Data organisation

The dataset is grouped by type of product (here only analysis, an), level type (here only surface parameter, sfc), by step (here always 0) or forecast range (here always 0) and by parameter. Biomass burning emissions are available on a daily basis, always with time 12:00:00.


z_macc_c_ecmf_20140129120000_gfas_an_sfc_000_co2fire.grib contains analysis field of biomass burning emissions of CO2 on 29th January 2014 (valid 0 UTC on 29th to 0UTC on 30th).

z_macc_c_ecmf_20140129120000_gfas_an_sfc_000_tcfire.grib contains analysis field of biomass burning emissions of Carbon on 29th January 2014.

Data availability

The latest forecasts are normally available by 06:00 UTC. After the data transfer to the ftp server is completed a manifest file is uploaded:


This is a text file which contains the list of all the files and is uploaded only when all the data is available.
