European surface UV radiation (EUV) product and data record (demonstrational)

Description

Demonstrational status means that the product is available to the users but it hasn't been officially reviewed nor released and thus, the documentation and/or the full validation results may be missing. The user feedback, comments and evaluations are highly appreciated during the demonstrational period and that information will be used either in the further development of the product or directly in the final review and release process if the product is mature enough from the users' point of view.

European surface UV radiation product covers Europe and combines total column ozone measurements from the GOME-2 instrument on the polar orbiting Metop satellites with cloud optical depth retrievals from the geostationary Meteosat satellites.
