Scope
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.
...
- Log on to www.ecmwf.int. (If you do not have an account create one)
- Read the CAMS data licence and accept the license at the bottom of the page.
- Contact us by creating a ticket through the ECMWF Support Portal (Charts and Data > Get our products ), providing Send an email to copernicus-support@ecmwf.int, providing
- the user name you used to log into www.ecmwf.int and accept the license
- for our service planning, a brief description of how you intend to use the data
Data location
FTP server | ftp://disseminationaux.ecmwf.int |
|---|---|
Data directory | /DATA/CAMS_GFAS/${YYYYMMDD} /DATA/CAMS_GFAS_HOURLY/${YYYYMMDD} /DATA/CAMS_GFAS_TEST/ (for test data files) |
Retention policy | Data is kept for 7 days for CAMS_GFAS Data is kept for 3 days for CAMS_GFAS_HOURLY |
File naming convention
The CAMS_GFAS file naming convention is based on WMO guidelines as follows:
z_cams_c_ecmf_yyyymmddhhmmssyyyymmdd000_vvvv_tt_lt_sss_param.[grib|nc]
Where:
ecmf | is the WMO location indicators. The list can be found here. |
yyyymmddhhmmssyyyymmdd | is the base date and time of the forecast. |
vvvv | is 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. |
tt | type of data, fc - forecast, an - analysis |
lt | is the type of level. sfc for surface fields, ml for model level fields, pl for pressure level products, |
param | is the parameter short name as defined here |
| is the format of a file, GRIB or NETCDF |
The 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]
Where:
ecmf | is the WMO location indicators. The list can be found here. |
yyyymmddhhmm | is the base date and time of the forecast. |
vvvv | is 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. |
tt | type of data, fc - forecast, an - analysis |
lt | is the type of level. sfc for surface fields, ml for model level fields, pl for pressure level products, |
sss | is 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 |
param | is the parameter short name as defined here |
| is the format of a file, GRIB or NETCDF |
Data organisation
The dataset is datasets are 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.Examplesrange 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_20140129120000202012280800_gfas_an_sfc_000024_co2fire.grib contains 24-hour average analysis field of biomass burning emissions of CO2 on 29th January 2014 28th December 2020 (valid 0 from 08 UTC on 29th 28th to 0UTC 08 UTC on 30th29th).
z_cams_c_ecmf_20140129120000202012290700_gfas_an_sfc_000001_tcfireco2fire.grib contains hourly analysis field of biomass burning emissions of Carbon CO2 on 29th January 2014December 2020 valid at 07 UTC.
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:
