Deterministic AIFS forecast (Set IX - AIFS)

Single forecast runs by the ECMWF Artificial Intelligence Forecasting System (AIFS) deterministic model.

  • 4 forecast runs per day (00/06/12/18)
  • 6 hourly steps to 360 (15 days)

While the data is freely available as open data, access can be purchased so that it can be disseminated to customers the same way as other data ECMWF produces. More details including licences and parameters are described at page AIFS Machine Learning data. Notice access to AIFS ensemble is not yet available for purchase.
