Forecast charts and data

We provide global forecasts, climate reanalyses and specific datasets, designed to meet different user requirements. These are available via the web, point-to-point dissemination, data servers and broadcasting.

ECMWF’s operational forecasts aim to show how the weather is most likely to evolve. To do this, the Centre produces an ensemble of predictions. Individually they are full descriptions of the evolution of the weather. Collectively they indicate the likelihood of a range of future weather scenarios.
