The WMO LC-SSPMME for sub-seasonal predictions builds on the legacy left by the S2S project and relies on the S2S data base. Although the S2S project is completed, several operational and research centres continue to provide their forecast and re-forecast to the S2S archive.
The S2S archive confluence page is constantly updated and displays information about the data archived and about each contributing model. The S2S forecast is publicly accessible with a latency of 3 weeks.
Currently eight centres (referred as contributing centres) have agreed to provide the WMO LC-SSPMME with their forecast without the 3-weeks latency imposed by the S2S data policy. Such agreement is documented here. LC publish the forecast charts (individual and multi-model) once a week. The charts, based on the forecasts initialized around Thursday, are updated every Monday to give enough time for data to arrive.
CPTEC (Brazil) has recently applied for a GPC-SSF designation and agreed to contribute with its forecast data to the LC-SSFMME products. The CPTEC forecast will be included as soon as possible.
A list of contact points in case of problem with reception/encoding of data is available with restricted access.
