The following scores are to be calculated for all parameters against both analysis (except mean sea-level pressure) and observation:
Wind
Mandatory:
- rms vector wind error
- mean error of wind speed
Other parameters
Mandatory
- Mean error
- Root mean square (rms) error
- Correlation coefficient between forecast and analysis anomalies (not required for obs)
- S1 score (only for MSLP and only against analysis)
Additional recommended
- mean absolute error
- rms forecast and analysis anomalies (not required for observations)
- standard deviation of forecast and analysis fields (not required for observations)
