main research topics

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.

 

 

current main research areas are:

Measurements of the spatial and temporal distribution of spectral sky radiation

To understand and investigate a multitude of processes within the earth’s atmosphere, we perform measurements of the spatial and temporal distribution of spectral sky radiation with several instruments at IMUKs own roof platform.

Development of Instruments for spectral Measurements

Measurements of solar radiation are carried out in the optical spectral range from ultraviolet and visual to the near infrared. The needed measuring devices with their specific requirements are partly developed by the working group itself.

Solar radiation and impact on human health

Solar Radiation has both positive and negative effects for humans. Erythema and cancer are examples of the negative effects whereas the Vitamin D synthesis is an example for a very important positive effect. A main research area is the calculation of Vitamin D weighted UV-Exposure of humans.

Characterization of Measurement Uncertainties

For precise absolute measurements of solar radiation, it is necessary to examine the measurement uncertainties. For this purpose, it is essential to use various methods such as the Monte Carlo method.

Optimal orientation of photovoltaic systems

The productivity of solar PV systems depends highly on the orientation and collectors tilt angle. In this regard not only the position of the sun plays a major role but also the orientation of the system is strongly affected by clouds.
