Atmosphere Monitoring

Helping CAMS towards the market in Solar Energy Etienne Wey (TRANSVALOR S.A.) with contributions from M. Schroedter-Homscheidt (DLR), M. Marchand, L. Saboret (Transvalor) and Armines (L. Wald, M. Lefèvre, B. Gschwind)

Atmosphere Monitoring

What is CAMS radiation?

• 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 script

access possible • Managed and maintained by

Transvalor

The CAMS Radiation Service portal provides time series of clear sky (cloud-free) irradiation in global coverage and all-sky

irradiation in Europe/Africa/Middle East

CAMS Radiation Service users requests for new usages – Buildings, ligthing, energy

• 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

Atmosphere Monitoring

CAMS Radiation Service users requests for new usages – Biology and health

• 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

Conclusions

• CAMS radiation products are used for industry and research • The McClear and CAMS radiation statistics are showing an

increasing usage, with a broadening outside of the Solar Energy field

• TRANSVALOR gets a continuous feedback from its users helping towards defining new and improved products and services
