Find in this page technical specification of the required input data and processing workflow.

Type:
- analysis (for instantaneous parameters)
- forecast (for accumulated parameters)
Products
- monthly mean of daily means (for instantaneous parameters)
- monthly mean of daily accumulations (for accumulated parameters)
Output times: depends on the model

Name	units	paramId^*1	shortName^*1	longName^*1
Time-mean 2 metre temperature	K	228004	avg_2t	Time-mean 2 metre temperature
Time-mean mean sea level pressure	Pa	235151	avg_msl	Time-mean mean sea level pressure
Time-mean total precipitation	kg m^-2	228228	tp	Total Precipitation

All details about the required data format can be found in the page Encoding details.

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

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.

Contact Richard Mladek for any further details, sample data exchange etc.
