1. 1. Detection of slush on the Greenland Ice Sheet using Moderate Resolution Imaging Spectroradiometer (MODIS) satellite imagery

   Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Viktor Wu; [2020]
   Nyckelord :slush; Greenland Ice Sheet GrIS ; surface mass balance SMB ; sea level rise SLR ; satellite imagery; Earth and Environmental Sciences;

   Sammanfattning : Sea Level Rise (SLR) is a growing global concern that is heavily influenced by a warming climate. Because of a potentially large added mass to the ocean through ice melt, the Greenland Ice Sheet (GrIS) plays an important role in the contribution to SLR. LÄS MER

3. 2. Impact of different atmospheric forcings on surface mass balance estimates in Greenland

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Stina Olandersson; [2018]
   Nyckelord :Physical Geography and Ecosystem analysis; surface mass balance; Greenland; climate models; numerical weather prediction models; surface energy balance; Arctic; climate change; Earth and Environmental Sciences;

   Sammanfattning : The Greenland Ice sheet (GIS) is the second largest ice sheet on Earth and thus stores a large amount of Earths freshwater. Because of climate change and the Arctic amplification, GIS is experiencing changes and increased melt rates. The total mass budget determines the amount of sea level rise caused by input from freshwater from the GIS. LÄS MER

4. 3. Climate Change and Precipitation Variability Influence on the Greenland Ice Sheet

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Författare :Jennie Olsson; [2018]
   Nyckelord :Physics; Ice Sheet; Surface Mass Balance; SMB; Representative Concentration Pathways; RCP; Climate Change; Greenland; Precipitation; Precipitation Variability; Glaciers; Glacier; Meteorology; Greenhouse Effect; Greenhouse Gas; Future Climate; Climate; Physics and Astronomy;

   Sammanfattning : Climate changes have a large impact on precipitation patterns and precipitation variability change. With this in mind, precipitation over Greenland is studied. This is done for present day precipitation model data from 1991-2010 compared to future model simulations of precipitation for 2081-2100. LÄS MER

5. 4. A comparison of modelled precipitation in Greenland

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Författare :Rebecca Vesterberg; [2017]
   Nyckelord :Greenland; precipitation; Surface mass balance; SMB; ice sheet; accumulation; ablation; sea level rise; Regional Climate Model; HIRHAM5; Numerical Weather Prediction model; HIRLAM7.3; biases; climate change; Physics and Astronomy;

   Sammanfattning : The Greenland ice sheet develops throughout the year with the changing weather condi- tions. Precipitation contributes by increasing the mass, whilst warmth induces melting, which makes the ice sheet diminish. LÄS MER

7. 5. Modeling albedo in the dry snow zone of the Greenland ice sheet

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Författare :Johanna Eggeling; [2014]
   Nyckelord :Earth and Environmental Sciences; Physics and Astronomy;

   Sammanfattning : Hirham5, a weather model developed at DMI, does not have a very good approximation for the snow albedo. To make the model better a snow albedo code, based on Dickenssen’s equation for snow albedo, was implemented in the model where the albedo depended on more variables than just the temperature. LÄS MER
