About

S2S, sub-seasonal to seasonal prediction project, is a WWRP/THORPEX-WCRP joint research project established to improve forecast skill and understanding on the sub-seasonal to seasonal time scale, and promote its uptake by operational centres and exploitation by the applications community.

CMA, one of the two S2S data archiving center, is responsible for collecting the S2S data from all data providers, performing basic quality check, archiving into both the MARS system and the online disk storage, and providing data service.

The S2S data portal provides both free text and faceted search method to access forecast and reforecast data in format of GRIB2. Up to now, list of parameters provided by each partner is here.

7th International Verification Methods Workshop (7IVMW), 3-11 May 2017, Berlin, Germany The Seventh International Verification Methods Workshop is being organised by the WMO Joint Working Group on forecast Verification Research and will be hosted in Berlin, Germany, jointly by the Free University of Berlin, the Max-Planck-Institute for Human Development, the Hans-Ertel-Centre for Weather Research (HErZ) and the German Weather Service DWD, from May 3 - 11, 2017. The goal of the workshop is to discuss and promote all aspects of verification methodology research and practice, as applied to weather forecasts and warnings, climate predictions, and their applications. Special sessions are planned on verification methods for sub-seasonal and longer range forecasts. Participants are welcome from operational, research and forecast user communities.
