Data location
FTP server | ftp://dissemination.ecmwf.int |
|---|---|
Data directory | /DATA/CAMS_GFAS/${YYYYMMDD} |
Retention policy | Data is kept for 7 days |
File naming convention
The file naming convention is based on WMO guidelines as follows:
z_cams_c_ecmf_yyyymmddhhmmss_vvvv_tt_lt_sss_param.[grib|nc]
Where:
ecmf | is the WMO location indicators. The list can be found here. |
yyyymmddhhmmss | 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. pl for pressure level products, sfc for surface fields, ml for model level fields |
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 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.
