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.

It is important to provide consistent verification information on the Numerical Weather Prediction (NWP) products produced by different centres for the benefit of operational forecasters and to help the centres compare and improve their forecasts. CBS has therefore defined detailed procedures for the production and exchange of a standard set of verification scores for deterministic NWP forecasts produced by WMO GDPFS centres.

Scores are 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.
