Forschungsschwerpunkte
Wolken sind ein wichtiger Faktor für die Strahlungsbilanz der Erde. Der wissenschaftliche Schwerpunkt dieser Arbeitsgruppe liegt darin, die wesentlichen Prozesse, welche die Strahlungseigenschaften von Wolken bestimmen, zu verstehen und zu quantifizieren. Zu diesen Prozessen zählen z.B. die Wechselwirkungen zwischen Aerosolen, Wolken und der Strahlung sowie Wechselwirkungen zwischen Aerosolen, Wolken und der gross-skaligen Dynamik.
Instrumente und Methoden
Wir verwenden hauptsächlich numerische Modelle im Zusammenhang mit Satelliten- und Feldbeobachtungen. Die Skalen und Komplexität der Modellierung reichen von idealisierten Large-Eddy Simulationen (LES) bis hin zu globalen Klimamodellen voller Komplexität.
