Thermal Infrared Remote Sensing


The TIRLab at RSL works on the acquisition and use of thermal infrared datasets across scales (in situ, drone-based, space-borne, models) and spheres (bio-, cryo- and hydrosphere). TIR datasets carry a large potential to improve our understanding of the Earth surface energy balance. However, the great spatio-temporal variability of Land Surface Temperatures (LSTs) challenges an accurate spatially distributed acquisition of data.
Our science focuses both on fundamental TIR research and solution-oriented studies. We investigate spatio-temporal variabilities, directional effects and biophysical variables such as evapotranspiration by means of TIR data obtained by varying instruments and combined with information of other environmental variables. Across-scale experiments shall identify potential and limitations of upcoming TIR satellite data (Trishna, LSTM, SBG) for environmental studies in the context of global atmospheric warming.
