Radiation and Remote Sensing
Our main research interest is to characterize solar radiation and its spatial and temporal behaviour. Solar radiation is altered by several factors like clouds, atmospheric gases, aerosols and ground albedo. We want to understand the changes imposed by these factors quantitatively. Finally we are interested in the impact of the solar radiation on humans and the environment.
For this purpose we develop new measurement systems as well as quality control and quality assurance procedures. Especially the difficulties to measure the solar UV component are often underestimated. Consequently it has been a major goal of both research and education in the recent two decades to develop methods for reliable measurements and to implement those in databases, such as the European UV database or the Network for the Detection of Atmospheric Composition Change. Several documents describing reliable UV measurements have been produced for the Global Atmosphere Watch program of WMO.
