where

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 he elevation of the observation station above the mean sea level in meters;
parameter is the parameter and level of the verified model parameter:

parameter	description
t2m	air temperature at 2 meters above the model orography surface and corrected to the station actual elevation using the constant lapse rate 6K/1000m
tp24	total precipitation accumulated over previous 24 hours
ff10m	wind speed at 10 meters above the model orography surface

score

description

me

mean error (bias), computed as FC-OBS

ct

contingency table, the 4 values are Misses,Hits,CorrectRejections,FalseAlarms

	observed	not observed
forecast	Hits	FalseAlarms
not forecast	Misses	CorrectRejections

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

sample_size is number of observations use to compute the monthly mean at the given station;
mean_value is the value or values of the score mean; in case of contingency table these are the 4 values delimited by comma
