The Sub-seasonal to Seasonal(S2S) dataset consists of global ensemble forecasts from thirteen numerical weather prediction (NWP) centres, starting since January 2015.
The S2S prediction project is a joint initiative of the World Weather Research Programme (WWRP) and the World Climate Research Programme (WCRP). The goal of S2S is to improve the forecast skill and understanding on the sub-seasonal to seasonal timescale, and to promote its uptake by operational centers and exploitation by the applications community.
Although the 10-year (2013-2023) S2S program has already ended, the archive has continued and is currently undergoing its next five-year phase (2024-2028).
Please consult the Documentation section provided with this entry since it is a crucial resource for understanding the dataset, as it provides all the necessary information, including data sources, model configurations, and limitations.
