z_cams_c_ ecmf_20160704000000_prod_fc_pl_012_co.grib contains all the pressure levels of +12 step CO fields from a forecast started on 7 July 2016 at 00:00 UTC.

z_cams_c_ ecmf ecmf_20160704120000_prod_fc_ml_012_go3.nc nc  contains all the model levels of step 12 O3 fields from a forecast which was started on 7 July 2016 at 12:00 UTC in NetCDF format.

Data

...

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.

List of available parameters

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.
