On a side note the ECMWF AI Ensembles package will launch July
https://events.ecmwf.int/event/487/
On Tuesday 1 July 2025, the first version of the Artificial Intelligence Forecasting System (AIFS) Ensemble model will be released and supported operationally. This release marks another milestone in ECMWF history, as AIFS ENS v1 will be the first AIFS ensemble model to be made fully operational.
AIFS ENS, v1 model will not be an upgrade of currently experimental diffusion AIFS ENS model. It is a first version of a new model that is trained using a version of the Continuous Ranked Probability Score (CRPS), a loss function that helps ensure the forecasts are both accurate and well-calibrated.
In addition to operationalisation of AIFS ENS, v1 will bring several new data and graphical probabilistic prodcuts available in the EMCWF Open charts platform.
