The CAMS Radiation Service portal
• start in 2004• after 1-2 days delay online
• global, diffuse, direct and direct normal irradiation
• time series• 1 min, 15 min, 1 hour, 1 day,
1 month temporal resolution
• interactive and OGC scriptaccess possible
Time series of clear sky (cloud-free) irradiation in global coverage and all-sky irradiation in Europe/Africa/Middle East

CAMS Radiation Service new usages
• Selecting publicly available, representative solar radiationmeasurements to show added value of new solar technologies (EC PreFlexMS project)
• Consultancy in energy monitoring of buildings• Optimization algorithm for residential buildings• Spectral distribution of the surface incident irradiation –
effect on the PV cell technology• Low altitude solar drone flight time optimization• Study of a generic hybrid ventilation system• Solar irradiation variations for video generation and photography• Model of a train track temperature from meteo data
and GHI & DNI
AtmosphereMonitoring
CAMS Radiation Service new usages
• Bioenergy - PAR data for microalgae growth• Radiation effect on the development and toxicity of
cyanobacterial blooms in reservoirs• Water disinfection by solar radiation (UV)• Synthesis of protective compounds such as flavonoids in plants -
color of iris flowers, as an answer to UV stress• Influence of UV doses and other meteorological data on the
“inula montana” in the Luberon mountain area• Impact of solar radiation on grapes and wine aroma –
modelisation of grape surface temperature dynamics• Study to demonstrate that UV-B exposure, as a surrogate for
vitamin D levels, contributes to prevent from Parkinson disease
