Larsen, E.; Storm, D., 2023, "Modelling Snow Water Equivalent, A Research Project with GEUS on Greenland Ice Sheet Data", https://doi.org/10.22008/FK2/NAPVQX, GEUS Dataverse, V1
Abstract: Measuring snow water equivalent (SWE) is time-consuming, costly, and at times even simply impossible in remote locations such as on the Greenland ice sheet. This motivates the modelling of SWE from more easily accessible input variables such as snow depth. This study ap... |

Todd H. Albert, 2007, "Assessment of glacier mass balances from small tropical glaciers to the large ice sheet of Greenland", https://doi.org/10.22008/FK2/DQRE71, GEUS Dataverse, V1
A combination of field work, modeling, and remote sensing was used to determine mass balances for the Quelccaya Ice Cap in Peru and for parts of the Greenland Ice Sheet. A 40-year history of deglaciation on Quelccaya derived from satellite is presented. Automatic Weather Station... |

Wim Damgaard Rothuizen; Thomas Anthony Hymas, 2020, "Albedo regression of the Greenland ice sheet", https://doi.org/10.22008/FK2/QWZ5HL, GEUS Dataverse, V1
The project investigates the use of machine learning regression algorithms to estimate the broadband albedo factor on the Greenland Ice Sheet. The algorithms use data from the Ocean and Land Color Instrument (OLCI) on the Sentinel 3 Satellite and compare it to in-situ measurement... |

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... |

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... |

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... |

Kacperski, Kamil, 2020, "Mapping the hydrological system of the Greenland ice sheet in coarse satellite products with a machine learning approach", https://doi.org/10.22008/FK2/YWC9XA, GEUS Dataverse, V1
This paper utilizes supervised machine learning approach to infer presence of water features in Moderate Resolution Imaging Spectroradiometer imagery of Greenland ice sheet in the area UPE_U PROMICE automatic weather station (AWS). Reference dataset consisted of water feature mas... |

Aaslyng Dall, Maja, 2020, "Validation of remotely sensed snow liquid water content on the Greenland ice sheet at the PROMICE weather station sites", https://doi.org/10.22008/FK2/HQAEW3, GEUS Dataverse, V1
Surface melt on the Greenland Ice Sheet has been estimated using L-band radiometer data measured by the SMOS satellite. This data has previously been validated with the focus of correct binary detection of melt. In this thesis, the validation will extend to correct detection of t... |

Wu, Victor, 2020, "Detection of slush on the Greenland Ice Sheet using Moderate Resolution Imaging Spectroradiometer (MODIS) satellite imagery", https://doi.org/10.22008/FK2/8WAXJH, GEUS Dataverse, V1
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. The presence of slush on G... |
