Atmospheric model Analysis runs for the four main synoptic hours 00, 06, 12 and 18 UTC; forecast runs out to 10 days based on the 00/12 UTC analysis forecast. Data is produced at the surface, on model levels, pressure levels, isentropic levels and levels of … ...
A vast amount of data is archived daily containing IFS (Integrated Forecast System) experiments produced by ECMWF's Research Department or by Member States' users at ECMWF. Basically, an experiment can address any area of meteorology and it is archived … ...
A subset of ECMWF real-time forecast data 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, … ...
ERA5 is the fifth generation ECMWF atmospheric reanalysis of the global climate covering the period from January 1940 to present. ERA5 is produced by the Copernicus Climate Change Service (C3S) at ECMWF. ERA5 provides hourly estimates of a large number of … ...
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 … ...
ECMWF is now running its own Artificial Intelligence Forecasting System (AIFS) as part of its experiment suite. The AIFS consists of a deterministic model and an ensemble model. Further details about the deterministic model can be found at … ...
The SOFF (Systematic Observations Financing Facility) initiative from the WMO is aimed at supporting beneficiary countries to generate and exchange GBON (Global Basic Observing Network) data. These data are critical for improved weather forecasts and climate … ...
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 … ...
