Description:
During their lifetime, total solar irradiance (TSI) radiometers are exposed to different environmental conditions and processes that may degrade the coating that is used as absorber of the incoming radiation to be measured. We were able to reproduce in the laboratory the degradation observed in space with PMO6-type radiometers in instruments like PREMOS, using high-intensity UV light and show that a novel carbon nanotube coating does not degrade under the same conditions.
