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)
| Table of Contents |
|---|
Parameters
Output frequency: the model output steps should be between 1 and 12 hour
- Output types: forecasts and analysis
...
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):
Code Block 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.
