- centre (4-characters string) is the WMO identifier of the originating centre (ammc, cwao, ecmf, edzw, egrr, kwbc, lfpw, rjtd, rksl, rums etc);
model_id (variable-length string) is free model identifier assigned by the originating centre (to distinguish between potentially different models provided by the centre);
- yyyymm is the month of the mean, where yyyy is the year and mm is the month (01-12);
- time is the time (in hours UTC) when the forecasts included in the mean have been validating;
- forecast_step is the length of the forecast (in hours);
- station_id is the name and/or numeric ID of the observation station verifying the forecasts;
- latitude is the latitude of the observation station verifying the forecasts;
- longitude is the longitude of the observation station verifying the forecasts;
- station_elevation is the elevation of the observation station above the mean sea level in meters;
- parameter is the parameter and level of the verified model output parameter:
| parameter | description | unit |
|---|---|---|
| t2m | air temperature at 2 meters above the model orography surface and , corrected to the actual station elevation using the constant lapse rate 6.5K/1000m | K |
| td2m | dewpoint at 2 meters above the model orography | K |
| rh2m | relative humidity at 2 meters above the model orography | % |
| tp06 | total precipitation accumulated over previous 6 hours | mm |
| tp24 | total precipitation accumulated over previous 24 hours | mm |
| ff10m | wind speed at 10 meters above the model orography | m/s |
