Our research interests focus on the role of vegetation, its composition and structure, on land surface processes and climate feedbacks. Radiation is one of the key factors linking land surface and atmospheric processes. At the same time, radiation is a limiting growth factor of vegetation, be it in the short wavelength range as photosynthetically active radiation or in the longwave domain as temperature. Our goal is to contribute to ecological and climatological questions through combined field and satellite radiation measurements, radiative modelling, and ecological experimental approaches, from the plant to the landscape scale.
The emphasis lies on continuous process-related ecosystem variables (e.g. albedo, plant traits), going beyond traditional land cover types with spatially discrete class boundaries. Our focus is on vegetation dynamics, biodiversity and related permafrost-vegetation-atmosphere processes in Northeastern Siberian tundra.

Head of group: Prof. Dr. Gabriela Schaepman-Strub
