Parameters
Output type: forecast
only one forecast product per centre is expected for verification - the best available one for the common inter-comparison
- Output time:00 and 12 UTC
Output frequency: between 1 and 6 hours (including step 0 encoded as forecast type as well)
- the model output steps should be the shortest available

- 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>fc.grib2
acronym listed in the table below
prod/test ... production or test version of the data
an/fc ... analysis or forecastforecast (step 0 should be also encoded as of forecast type) - 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:
Show If special @anonymous Alert Log in to see ftp details
Show If special @authenticated Code Block host: ftp.ecmwf.int user: observations passwd: observations2013 directory: wave
- The naming convention for future production data might change
