model_id (variable-length string) is free model identifier assigned by the originating centre (to distinguish between potentially different models provided by the centre);
| parameter | description |
|---|---|
| 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 |
| tp24 | total precipitation accumulated over previous 24 hours |
| ff10m | wind speed at 10 meters above the model orography |

| me | mean error (bias), computed as forecast minus observation | |||||||||
| ct | contingency table, the 4 values are misses, hits, correct non-events, and false alarms (in this order)
|
| event | description |
|---|---|
| val>1 | forecast/observed value greater than 1 unit of the forecast parameter |
| an>4 | forecast/observed anomaly with respect to the station climate mean greater than 4 units of the forecast value |
| an<-1.5std | forecast/observed anomaly with respect to the station climate mean less than -1.5 times the standard deviation of the climate at the observation station |
