Probabilities: 24h precipitation
The plot shows probability information derived from the ensemble forecast system (ENS), specifically the Probability of 24-h accumulated precipitation (rain and snow) exceeding 1 mm (colour shading in %).
The probabilities are based on the number of forecast members which meet the criteria (each member is assigned an equal probability of 1/50).
Detailed description of ENS probabilistic products can be found in ECMWF Forecast User Guide.
Forecast charts and data
We provide current forecasts, climate reanalyses and specific datasets. These are available via the web, point-to-point dissemination, data servers and broadcasting.
Forecasts, analyses, climate reanalyses, re-forecasts and multi-model data are available from our archive (MARS) or via dedicated data servers or via point-to-point dissemination.
Researchers, WMO members, commercial users and satellite data providers can gain access to ECMWF forecast products under one of our various licence agreement types.
Serving meteorology
International collaboration is fundamental to the work of ECMWF, working with the EU and the meteorological community at large, including the World Meteorological Organization, space agencies, and scientists around the world.
ECMWF workshops are open to the worldwide meteorological community, though some training is restricted to member states.
