Actinic Radiation Measurements

Spectral and integral radiation quantities can be determined with a number of instruments under field- and laboratory conditions.

Actinic radiation measurements to determine photolysis frequencies have been made since many years at IEK-8. Absolutely calibrated spectral radiometers and filter radiometers are used for that purpose. These instruments are deployed for ground based field measurements, for experiments in the atmosphere simulation chamber SAPHIR, and on mobile platforms like the Zeppelin-NT. In addition the spectral radiometers can serve as a reference for instruments of other institutions. A roof platform with subjacent laboratory is available for such comparisons under field conditions. Moreover, measurements can be made to characterise photochemical laboratory reactors and simulation chambers.
