Warning

From 18th October 2022 at 15:00UTC, our FTP server has changed from ftp://dissemination.ecmwf.int  to ftp://aux.ecmwf.int

From 18th October 15:00UTC, no new data will be published on dissemination.ecmwf.int

...

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

...

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:

Code Block
# CCSDS -> simple

grib_set -r -s packingType=grid_simple in.grib2 out.grib

# Simple -> CCSDS

grib_set -r -s packingType=grid_ccsds in.grib out.grib2

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.

Note

Due to the new compression method used, the GRIB file sizes vary much more than before. I In this table the numbers are averages.

* Please be aware that, the total volume will vary from one model run to the next one.
