WMO Lead Centre for Deterministic Forecast Verification (WMO-LCDNV)
The 16th Congress (2011) of the World Meteorological Organisation (WMO) approved the recommendation from its Commission for Basic Systems (CBS-Ext.(2010)) to establish a Lead Centre for Deterministic NWP Verification (LC-DNV) and to designate ECMWF as this Lead Centre.

Scores will be exchanged between the participating producing centres via the LC- DNV. The role of the LC-DNV is to facilitate this standardised verification, to ensure the routine exchange of the required verification results between centres and to provide consistent comparisons of these results.
CBS standard verification procedures for determinisic NWP products
The CBS standardised procedures for verification of deterministic NWP products are defined in the Manual on the GDPFS, Volume 1, Part II, Attachment II.7, Table F.
