During Summer 2005 Flyby srl has delivered the MEDSUN public service with the supervision of the Regional Agency for Environmental Protection of Tuscany (ARPAT). The MEDSUN service, funded by the GSE-PROMOTE ESA program, provided a personalized safe sun exposure time by correlating the EO based UV Index with the customized personal phototype. The UV Index was a function of both EO based columnar Ozone and EO based cloud coverage. The Ozone was derived from SCIAMACHY/ENVISAT by KNMI. The cloud coverage was derived from SEVIRI/MSG by Flyby. The article presents the features of MEDSUN service and the results of two validations based on on-ground measurements. The first validation regards the EO based UV Index and was done using a UV broadband radiometer. The second validation regards the EO based total columnar Ozone and was done using Flyby's spectroradiometer SpectrAIR.
