Marianne Böhm is a Master’s student of climate and environmental change at the Friedrich-Schiller-University Jena (Germany), where she works in a group that focuses on applications of remote sensing for describing properties of forests. Her main interests are climate change impacts on forests as well as high-latitude ecosystems and their carbon cycle.

Her poster presented the results of comparing observations from several satellite-borne sensors operating in the microwave spectrum on their capacities to characterize forest structure, using LiDAR-derived indices as reference. The results indicate that deriving forest structure from radar backscatter intensity alone, even in a multifrequency approach, will not be accurately possible. However, especially when L- and X-Band were used in synthesis, a certain proportion of backscatter variation appeared to be related to forest structure. This knowledge is relevant for further studies, either as a predictor, or confounding variable for other target information like biomass.
