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 sub-seasonal 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 service agreements to the World Meteorological Organization (WMO) and the academic and commercial sectors. A range of charts and datasets are publicly available free of charge.
