Welcome to the Lead Centre on Verification of Ensemble Prediction System Web site
World Meteorological Organization (WMO) CBS-XIII (2005) recommended that the general responsibilities for a Lead
Centre for Verification of EPS be added to the Manual on the GDPFS (WMO-No.485) and that the President designate RSMC Tokyo (Japan Meteorological Agency: JMA) as this Lead Centre.
Standard verification measures of the global EPS in Manual on the GDPFS
The standard verification measures of the global EPS are defined in Manual on the GDPFS (2017 edition, WMO-No. 485; available here), appendix 2.2.35. Because of the publication of the latest edition of the Manual, WMO GDPFS Centres are highly recommended grasping the changes in those measures form the previous edition of the Manual (2010 edition - updated in 2015; available here).
Climatology for verification
The climatology data used in the verification measures are available from the ftp server of the WMO Lead Centre for Deterministic Forecast Verification. Information on how to obtain access to the data is available here.
