centre=centre, model=model_id, d=yyyymm, t=time, s=forecast_step, st=station_id, lat=latitude, lon=longitude, lam=model_grid_latitude, lom=model_grid_longitude, se=station_elevation, me=model_orography_elevation, par=parameter, sc=score, th=event_thresholds, n=sample_size, v=meanscore_value

If the value of any key is unknown it is encoded as "na". However, every record has to have a valid meanscore_value (the "v" key); if the value is not known such record should not be included in the data file.

...

  • sample_size is number of observations used to compute the monthly mean at the given station;
  • meanscore_value is the value or values of the score mean computed based on the forecast initiating at time time UTC, verifying in the month yyyymm, for the forecast length forecast_step hours; in case of nxn contingency table these are the n2 values delimited by forward slashes (see the score table above).

(*) If the model grid or orography changed during the reported month (due to a model upgrade etc) the values of lam, lom and me should be those of the latest model run.
