format
Model level fields are in GRIB2 format. All other fields are in GRIB1, except for new parameters from cycle 48r1 (more details are available here). NetCDF format is also available.
| Note | ||
|---|---|---|
From cycle 48R1, there are important changes to the GRIB encoding for model levels fields, relating to packing and GRIB tables. Please see this page for full details: Implementation of IFS cycle 48r1 for CAMS#ChangetoGRIBencoding The 'packingType' can be changed using ECMWF's ecCodes:

Data availability
The latest model cycle based on the 00 UTC analysis is normally available by 10:00 UTC, the cycle based on 12 UTC analysis is available by 22:00 UTC.
After the data transfer to the ftp server is completed a manifest file is uploaded:
z_cams_c_ecmf_yyyymmddhhmmss_vvvv.manifest
The file is uploaded to the server only after all the data files have been successfully uploaded. The file contains a list of all the GRIB and NetCDF files in the cycle and their MD5 checksums in case you would like to verify data integrity.
