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 host via sftp:

Production data acquisition

  • The ECMWF's acquisition system (ECPDS) will be used for handling the production data exchange.
  • The data will be pulled via recommended protocol (sftp/https/aws etc) from an agreed server location at the data producer's site (please avoid using obsolete ftp).
    • alternatively providers can push their data to the provided ECPDS destination via recommended protocols
  • 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.
