ECMWF plans to use the operational Acquisition System to acquire the S2S real-time data for their ingestion in the S2S database.

The Acquisition System is based on the FTP protocol, using agreed filename patterns and frequency of data transfer. Once the data is at ECMWF computers, we will have suites to process, quality control and archive it. Note that the quality control will be limited, eg, check the GRIB headers and plot some fields.

Technical information to be provided by each partner:

s2s_${centre}_${version}_${stream}_${yyyy}${mm}${dd}${cycle}_${levelType}_${ensembleMember}.grib2

stream: enfo/enfh for real-time/reforecast outputs

version: test/prod

levelType: pl/sl/pt/pt/oc  for pressure/surface/potential temp/potential vorticity/ocean level

ensembleMember: 000, 001, 002.... (000 for control forecast, 001 for the 1st epsmenber etc)

example:  s2s_ukmo_prod_enfo_2019101000_pl_002.grib2

=> model outputs are split into separate files only by type of forecast (real-time or reforecast), level type and ensemble number (all steps and parameters are merged into one file)


General Principles:

Acquisition of re-forecasts:

Sample data

Steps to follow

  1. Provide technical information to establish data transfer. Send e-mail to:
    1. Ioannis.Mallas@ecmwf.int
    2. Richard.Mladek@ecmwf.int
    3. Manuel.Fuentes@ecmwf.int
  2. Routinely transfer test data for few weeks/months (version = test)
  3. Once everything is working, start transfer in 'Production' mode (version = prod)
