Research

Supervisors: Dr Gareth Marshall (BAS) and Dr Gareth Rees (SPRI).

Understanding future changes in snow cover in response to climate change is an important research field. This is principally because the extremely high albedo of snow means that changes in snow cover have a significant impact on the Earth's global energy budget. This project focusses on Northern Hemisphere snow cover, which comprises approximately 98 percent of the global total seasonal snow and which is responsible for the largest annual and interannual differences in land surface albedo. Using remote sensing, meteorological observations and field data, changes in snow cover of the Kola Peninsula in Arctic Russia will be analysed. Field measurements of snow parameters will be used to ground-truth the satellite data: MODIS (Moderate Resolution Imaging Spectroradiometer) fractional snow cover and albedo products. The initial focus on the area around the Khibiny Mountains in the Kola Peninsula will subsequently be extrapolated to obtain a wider regional picture, focussing on Fennoscandia. Atmospheric reanalysis data will be utilised to determine how atmospheric circulation variability affects the regional snow cover. Based on these relationships, and the output from a regional climate model (Weather Research and Forecasting model) forced by future runs from the best CMIP (Coupled Model Intercomparison Project) models, snow cover predictions will be made until the end of the century based on the four main IPCC (Intergovernmental Panel on Climate Change) emission scenarios.
