The firn meltwater retention model intercomparison project (RetMIP): model outputs
Nov 2, 2020
Vandecrux, Baptiste; Peter L. Langen; Peter Kuipers Munneke; Sebastian Simonsen; Vincent Verjans; C. Max Stevens; Sergey Marchenko; Ward van Pelt; Colin Meyer, 2020, "The firn meltwater retention model intercomparison project (RetMIP): model outputs", https://doi.org/10.22008/FK2/CVPUJL, GEUS Dataverse, V2
This dataset comprises the outputs from nine firn models at four sites of the Greenland ice sheet produced for the firn meltwater Retention Intercomparison Project (RetMIP). The nine models were forced by the same weather-station-derived mass and energy fluxes. The simulated firn...

Snow and Firn temperature on the Greenland’s ice sheet
Sep 11, 2020 - Student reports
Rasmussen, Magne E., 2020, "Snow and Firn temperature on the Greenland’s ice sheet", https://doi.org/10.22008/FK2/59EKFO, GEUS Dataverse, V2
Firn temperatures from the Greenland ice sheet have been collected, analyzed and combined to perform results concerning selected locations and the entire ice sheet. The purpose has been to investigate whether the recent atmospheric warming observed at the Greenland ice sheet has...
Remote sensing of Greenland ice sheet surface characteristics using Sentinel 3 satellites

Schweisthal, Louis, 2020, "Remote sensing of Greenland ice sheet surface characteristics using Sentinel 3 satellites", https://doi.org/10.22008/FK2/CNQASU, GEUS Dataverse, V1
In recent decades, changes of global climate have had a profound effect on the cryosphere and in particular on polar glaciers. These glaciers, such as those in Greenland, have an important role in the global climate regulation via their low albedo, drive major currents by pouring...
The Effects of Meltwater, Refreezing and Modelled Grain Size on Snow Albedo: Gaining Knowledge from Observations at Weather Stations and Numerical Modelling
Sep 11, 2020 - Student reports
Saunderson, Dominic, 2020, "The Effects of Meltwater, Refreezing and Modelled Grain Size on Snow Albedo: Gaining Knowledge from Observations at Weather Stations and Numerical Modelling", https://doi.org/10.22008/FK2/LF0F4X, GEUS Dataverse, V1
The extent to which snow and ice surfaces undergo melt is mainly dictated by their absorption of shortwave radiation, and thus the surface albedo is a critical parameter for accurately modelling the surface energy balance and mass balance of the Greenland Ice Sheet (GrIS). Multip...
