Fernerkundung der Landoberfläche

Forschungsinteresse

Permafrost ist eine sogenannte essentielle Klimavariable. Es ist ein unterirdisches Phänomen, das nicht direkt mit Fernerkundung gemessen werden kann. Viele Parameter, die das thermische Regime des Bodens und Oberflächenindikatoren beeinflussen, können jedoch mit Satellitendaten erfasst werden. Wir untersuchen hydrologische Veränderungen an der Landoberfläche in der Arktis. Dazu zählen vor allem die Überwachung von Tauseen, Schneeverhältnissen und Oberflächenfeuchte mit Satellitendaten.
