The amount of snowfall (accumulation) in the past centuries and millennia over the Greenland ice sheet is important if we are to understand the current state of the ice sheet. In recent years, radar data have been used more and more to estimate these accumulation rates. Radar data show the old snow layers. The deeper the layer, the more accumulation has been added since it was deposited.
In this project, radar data from a region of interest (for example, Central Greenland, Petermann area, Northeast Greenland etc.) will be used together with different modelling approaches to calculate the past accumulation. Different model approaches include inverse methods, ice-flow models or densification models depending on interest.
