Melting at the base of the Greenland ice sheet explained by Iceland hotspot history

I Rogozhina, AG Petrunin, APM Vaughan… - Nature …, 2016 - nature.com
Ice-penetrating radar,, and ice core drilling have shown that large parts of the north-central
Greenland ice sheet are melting from below. It has been argued that basal ice melt is due to …

Assessment of current methods of positive degree-day calculation using in situ observations from glaciated regions

LM Wake, SJ Marshall - Journal of Glaciology, 2015 - cambridge.org
The continued use of the positive degree-day (PDD) method to predict ice-sheet melt is
generally favoured over surface energy-balance methods partly due to the computational …

The glacial systems model (GSM) Version 24G

L Tarasov, BS Lecavalier, K Hank… - Geoscientific Model …, 2025 - gmd.copernicus.org
We document the glacial system model (GSM), which includes a 3D thermo-mechanically
coupled glaciological ice sheet model. The GSM is designed for large ensemble modelling …

The degree-day based method of calculating ice-/snow-melt across the Greenland Ice Sheet
(GrIS) commonly includes the temperature parameter sigma (σ) accounting for temperature …

Estimating Greenland surface melt is hampered by melt induced dampening of temperature variability

U Krebs-Kanzow, P Gierz, G Lohmann - Journal of Glaciology, 2018 - cambridge.org
The positive degree-day (PDD) model provides a particularly simple approach to estimate
surface melt from land ice based solely on air temperature. Here, we use a climate and snow …
