Scope
The ECMWF data portal (aux.ecmwf.int; SFTP/FTP/HTTPS data access) provides provides access to real-time daily and hourly data from the CAMS Global Fire Assimilation System (GFAS) . Daily data are GFAS version 1.2 and hourly data are GFAS version 14.2. GFAS hourly 1.4.1 data will be available while MODIS data is available, after access will stop.
The description documentation of GFAS v1.4.2 can be found found here.
Please see the list of available variables below and make sure your variables of interest are available.

File naming convention
The CAMS_GFAS file naming convention is based on WMO guidelines as follows:
z_cams_c_ecmf_yyyymmdd000_vvvv_tt_lt_param.[grib|nc]
Where:
...
is the parameter short name as defined here
...
grib, nc
...
The and CAMS_GFAS_HOURLY file naming convention is based on WMO guidelines as follows:
z_cams_c_ecmf_yyyymmddhhmm_vvvv_tt_lt_sss_param.[grib|nc]
...
The datasets are grouped by type of product (here only analysis, an), level type (here only surface parameter, sfc), by step or forecast range and range and by parameter.
CAMS_GFAS Example:
z_cams_c_ecmf_20201022000_gfas_an_sfc_co2fire.grib contains the average analysis field of biomass burning emissions of CO2 for 22nd October 2020 (valid from 00 UTC on 22nd to 00 UTC on 23rd).
CAMS_GFAS_HOURLY Example:
z_cams_c_ecmf_202012280800_gfas_an_sfc_024_co2fire.grib contains 24-hour average analysis field of biomass burning emissions of CO2 on 28th December 2020 (valid from 08 UTC on 28th to 08 UTC on 29th).
z_cams_c_ecmf_202012290700_gfas_an_sfc_001_co2fire.grib contains hourly analysis field of biomass burning emissions of CO2 on 29th December 2020 valid at 07 UTC.
Similar example applies also to CAMS_GFAS_HOURLY.
Data availability
Hourly fields data are produced at about 7.5 hours after their valid time.
24-hour rolling average fields are produced at about 1 day + 6.5 hours after their valid time.
Data might be available earlier but it is not guaranteed.
The latest forecasts are normally available by 06:00 UTC. After the data transfer to the sftp server is completed a , the relevant manifest file is uploaded:
z_cams_c_ecmf_yyyymmddhhmmss_gfas_024.manifest
z_cams_c_ecmf_yyyymmddhhmmss_gfas_001.manifest
This is a These are text file which contains contain the list of all the files and is are uploaded only when all the data is are available.
