Sensitivity of Svalbard glaciers to climate change
We investigate the energy and the mass balance of an Arctic glacier (Kongsvegen, Svalbard) and their interactions with the atmospheric boundary layer. The approach is based on extensive meteorological and glaciological observations and numerical modelling. Simulations are performed in local and spatially distributed modes aiming at better understanding of the atmospheric and subsurface exchange processes and the response of the glacier to changes of the meso-scale atmospheric conditions. In this context we also study the skill of different data sets and methods to derive spatially distributed data for initialisation and forcing of snow/ice energy balance models.
This is supported by detailed investigations of the distribution and structure of snow along the glacier, which is also of importance for investigation of internal refreezing processes and their impact on the energy and mass balance of the glacier. The project is embedded in an international research network focusing on the sensitivity of Svalbard glaciers to climate change.
