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 accordingly. Users wanting to retrieve Research experiments need to know in advance the name of the specific experiment and its nature. For this information please, contact User Support.

The Copernicus Climate Change Service (C3S) seasonal forecast service is based on data from several state-of-the-art seasonal prediction systems.

Bulk Wind Shearcharts show the vector value (in wind arrow form) of the shear between the low level, near surface level (10 m) and a mid-tropospheric level (about 6 km)...

The surface wind is influenced by the roughness of the earth's surface and is likely to be less strong, and a little backed (in the northern hemisphere) or veered (in the southern hemisphere)...

These charts show surface pressure patterns. Areas of high pressure (anticyclones) are usually associated with settled weather...

This chart shows 7-day mean anomalies of temperature at 10hPa from the ECMWF Sub-seasonal range ...

Dew Point Temperature at 2 m above the earth’s surface gives an indication of conditions which a person will experience or feel. High dewpoint temperatures inhibit heat loss from the body by perspriation and...

Temperatures at 2 m above the earth’s surface and winds at 10 m above the earth’s surface approximate most closely to the conditions that a person would experience.
