C3S Seasonal Forecasts

The Copernicus Climate Change Service (C3S) seasonal forecast service is based on data from several state-of-the-art seasonal prediction systems. The centres currently providing forecasts to C3S are: ECMWF, The Met Office, Météo-France, the German Weather Service (Deutscher Wetterdienst, DWD), the Euro-Mediterranean Center on Climate Change (Centro Euro-Mediterraneo sui Cambiamenti Climatici, CMCC), the US National Weather Service's NCEP (National Centers for Environmental Prediction, NCEP), Japan Meteorological Agency (JMA) and Environment and Climate Change Canada (ECCC). The home page for the service and products can be found here.

The C3S seasonal service currently offers graphical forecast products, available on the C3S web site, and public access to the real-time forecast and hindcast data, via the C3S Climate Data Store (CDS)
. Data are available from each of the components to the multi-system at a horizontal resolution of 1° x 1°, at daily/sub-daily time resolution and as monthly statistics (including monthly-mean anomalies). The period covered by the forecasts and hindcasts varies by forecast system and version. As the data is archived in MARS, it is also available there.

Detailed documentation is available, and the available data is described in this table. The CDS catalogue entries are listed under the ‘Explore this dataset’ button.
