Welcome to the Lead Centre on Verification of Ensemble Prediction System Web site

Lead Centre

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.
Since January 2004, JMA has operated two Internet sites for the Lead Centre works; a Web site and a FTP site. The FTP site is used for EPS producing centres to upload their statistics of EPS verification and the Web site is used to publish them.

Guide of EPS verification

The Manual on the GDPFS (WMO-No.485) is available at http://www.wmo.int/pages/prog/www/manuals.html
The Lead Centre prepared the guideline on the exchange and use of EPS verification results.
The climatology data based on the ERA-Interim analysis are available from the ftp server of the WMO Lead Centre for Deterministic Forecast Verification. The information on how to obtain access is here.

Publication of verification results

The statistics in the menu "Monthly Exchange" are made by each EPS centre.
The information of uploading the "Monthly Exchange" is here.
The visualized images in the menu "Monthly Diagrams" and "Timesequence" are made by the Lead Centre.
Verification results of some centers are still unavailable.
The information of reported parameters in "Monthly Exchange" is here.
