Land Surface Remote Sensing

Research Interest

Permafrost is an essential climate variable. It is a subsurface phenomenon, which cannot be directly measured with remotely sensed data. However, many parameters, which influence the ground thermal regime and surface indicators, can be captured with satellite data. We focus on changes of landscape hydrology and their impact in the Arctic. This includes monitoring of thaw lakes, snow conditions and surface moisture with satellite data.
