Find on this page technical specification of the required input data and processing for the WMO Lead Centre for Wave Forecast Verification project (LC-WFV)
Parameters
- Output time: 00 and 12 UTC
Output frequency: the model output steps should be between 1 and 12 hours (including step 0)
Output type: forecast
- Domain: regular latitude‐longitude grid at the resolution best matching the native resolution of the direct model output

Encoding
All details about the required input files including sample data can be found in the page Encoding details
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:
wave_<Organization_acronym>_<YYYYMMDDRR>_<prod/test>_<an/fc>.grib2
acronym listed in the table in the page GRIB data for WMO LC-WFV
prod/test ... production or test version of the data
an/fc ... analysis or forecast - Merge all parameters from all steps for given model run and output type into one file:
e.g. wave test forecasts from ECMWF on the 1st of September 2017, 12Z => wave_ECMWF_2017090112_test_fc.grib2 - Put sample data on ecgate to a directory with reading permission
- alternatively use any other downloadable location (e.g. google drive)
alternatively use this ftp (quota only 10 GB):
host: ftp.ecmwf.int user: observations passwd: observations2013 directory: wave
- The naming convention for future production data might change
Production
- 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.
