Greenland's ecosystems are witnessing unprecedented changes in response to climate warming. The intensity of feedbacks between the hydrosphere and vegetation change are not yet quantified in Greenland regions. This lends considerable uncertainty to predictions of how much, how fast and where the hydrosphere and ecosystems will change.

Quantifying the surface energy balance and its spatio-temporal trends in Greenland is a key to resolving these questions. The main scientific goal of this study is to estimate the spatio-temporal surface energy fluxes in the active vegetation growing season in selected Greenland ecosystems, by means of a two source energy balance model and a mapping framework.
