A flexible format for exchange of domain-averaged verification scores exchange has been defined :and described here. For format of station-based scores please look at the respective documents.

Format definition

Every score value is described by the full set of key attributes, like its parameter, domain, date, step etc. The keys describing one score value are organised into a record. Each record corresponds to one score value. A record is a collection of pairs key=value separated by commas. A record spans one line, records are separated by newline characters (CR). The value of a key missing in the current record is inherited from the key of the previous record, except for the value parameter v which has to be present in each record.

...

Order of key=value pairs is not significant; new keys can be added in future. Case of characters is insignificant, but it should be kept lower-case. Everything following the hash sign # till the end of line is ignored.

Units of values

Values should be of units following the definitions of scores in the WMO-CBS document on the updated standard verification system.

Example

# a sample bulletin with daily values, compressed by removing
# redundant (repeated) key=value pairs
centre=ecmf,par=z500hpa,sc=rmse,dom=nhem,ref=an,d=20110101,t=0,s=24,v=9.8
s=48,v=12.0
t=12,s=24,v=9.9
s=48,v=12.3
ref=ob,t=0,s=24,n=204,v=13.8
s=48,v=19.0
t=12,s=24,v=13.6
s=48,v=20.03
