Open data
A subset of ECMWF real-time forecast data from the IFS and AIFS models are made available to the public free of charge. Their use is governed by the Creative Commons CC-4.0-BY licence and the ECMWF Terms of Use. This means that the data may be redistributed and used commercially, subject to appropriate attribution.
AIFS forecast - AIFS Ensemble
Single forecast runs produced by the ECMWF Artificial Intelligence Forecasting System (AIFS) deterministic model.
AIFS forecast - AIFS Single
Single forecast runs produced by the ECMWF Artificial Intelligence Forecasting System (AIFS) deterministic model.
AIFS Machine Learning data
ECMWF is now running its own Artificial Intelligence Forecasting System (AIFS). The AIFS consists of a deterministic model and an ensemble model. The deterministic model has been running operationally since 25 February 2025; further details can be found on the dedicated Implementation of AIFS Single v1 page.
Machine Learning model data
ECMWF is now running a series of data-driven forecasts as part of its experimental suite. These machine-learning based models are very fast, and they produce a 10-day forecast with 6-hourly time steps in approximately one minute. The outputs are available in graphical form.
Currently, three of these models are available:
Datasets for African Center of Meteorological Application for Development
These products are available to the African Center of Meteorological Application for Development (ACMAD) countries.
The products outlined below are disseminated via EUMETCast
Please refer to WMO Additional products for the equivalent products available on a global domain via the ECMWF's DCPC FTP server.

WMO Additional
These products are only accessible for NMHS of WMO members under the following conditions. These products are only available with a 0.5° by 0.5° grid.
WMO Essential
These products are available to the public and their use is governed by the Creative Commons CC-4.0-BY licence. This means WMO Essential data may be redistributed and used commercially, subject to attribution.
These products are only available with a 0.5° by 0.5°grid.
Ocean Wave Model Ensemble 15-day forecast
Products based on an ensemble of forecasts providing an estimate of the reliability of a single forecast.
The purchase of the "Basic Set" +72, +96, +120, +144, +168 hrs is a mandatory prerequisite for the purchase of time steps in the range 12 to 66 hours.
The following sub-sets are available from the ENS-WAM:
Ocean Wave Model high resolution 15-day Forecast
HRES-WAM (High RESolution WAve Model) is coupled to the atmospheric model (HRES) and it is a Direct model output Products offers "High Frequency products":
- 4 forecast runs per day (00/06/12/18) (see dissemination schedule for details)
- Hourly steps to step 90 for all four runs
The model computes between the latitudes -78 and 90, the output grid is artificially extended to -90.
