Deterministic AIFS forecast (Set IX - AIFS)

Single forecast runs produced 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 are freely available as Open data, access can be purchased so that they can be disseminated to customers the same way as other data ECMWF produces. More details, including licences and parameters, are described on AIFS Machine Learning data. 

Access to AIFS ensemble model output data are not yet available openly or for purchase.
