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.

Assimilating soil moisture scatterometer data using neural networks

Patricia De Rosnay and colleagues discuss a recent study which uses neural network techniques to derive soil moisture from satellite observations. Neural networks are shown to outperform operational methods in some regions.

Datasets

Forecasts, analyses, climate re-analyses, reforecasts and multi-model data are available from our archive (MARS) or via dedicated data servers or via point-to-point dissemination.

Accessing forecasts

Researchers, WMO members, commercial users and satellite data providers can gain access to ECMWF forecast products under one of our various license agreement types.

Workshops and education

Education is a key element of our work at ECMWF, enabling our partners to get the most from ECMWF's services and develop an advanced understanding of forecasting.

ECMWF lecture theatre

ECMWF workshops are open to the worldwide meteorological community, though some training is restricted to member states.
