(b) Record format: slightly more complicated but more flexible, with the additional advantage that it is the same as the one proposed for very close to format used for WMO exchange of upper-air scores
The parameter keys and lists of parameters and scores are the same in both cases.

(b) Record format
Data file consists of score values and corresponding metadata in an ASCII format.

| centre=centre, model=model_id, d=yyyymm, t=time, s=forecast_step, st=station_id, lat=latitude, lon=longitude, se=station_elevation, me=model_orography_elevation, par=parameter, sc=score, ev=event, n=sample_size, v=mean_value |
If the value is not available the record either should not be given at all or the value should be set to NIL (v=nil); every record must contain the key v (value of key v is not inheritable from previous record).

Parameter keys
- 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 (a string, not containing a comma or vertical bar) 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 validity time (in hours UTC) of the forecasts verified;
- forecast_step is the length of the forecast (in hours);
- station_id (a number) is the WMO 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;
- model_orography_elevation is the elevation of the model orography at the observation location;
- parameter is the verified model output parameter:
