Sample data

• Providers are asked to provide full sample data from one model run containing all expected parameters, steps, forecast types etc.
• Naming convention for sample data:
  lcgcr_<centre WMO origin>_<YYYYMMDDRR>_<prod/test>_an.grib2
  prod/test ... production or test version of the data
• Merge all parameters from all steps for given model run and output type into one file:
  e.g. test reanalyses from ECMWF on the 1st of September 2017, 12Z  => lcgcr_ecmf_2017090112_test_an.grib2
• Put sample data on this ftp:

host: ftp.ecmwf.int 
user:
passwd:
directory: 

• The naming convention for future production data might change

Production data acquisition

• The data will be pulled via ftp from an agreed server location at the data producer's site.
• The ECMWF's acquisition system will be used for handling the production data exchange.
• Participants are committed to guarantee a steady and reliable provision of their data and to communicate any relevant changes.
• The support mailing list on provider's side will be required to allow smooth communication related to common production issues in the future.
