We produce operational ensemble-based analyses and predictions that describe the range of possible scenarios and their likelihood of occurrence.
Our forecasts cover time frames from the medium range to monthly and seasonal, and up to a year ahead.
We provide current forecasts, climate reanalyses, and specific datasets. These are available to the Member and Co-operating States, as well as through licensing to the World Meteorological Organization (WMO) and the academic and commercial sectors. Some charts and data are publicly available free of charge.
Since summer 2023, we have also been developing a machine learning model, the AIFS. This model is currently in its alpha phase, and experimental runs are available on our charts pages.
