ASSESSMENT AND POTENTIAL ADJUSTMENTS TO THE SNOW-RELATED ALGORITHMS IN BIOME-BGC, v4.2
… watersheds throughout the mountain west are snow-melt dominated. Recent studies suggest that climatic shifts throughout the 20th century have diminished snowpack around the west, a trend that may accelerate in the future. Loss of critical snowpack could negatively affect the ecosystems and …

Modeling the Thermal and Chemical Evolution of the Martian Lithosphere Over Time
… of the martian lithosphere. We developed a model that calculates the thermal state and melt composition of Mars over time. This model provides insight into the planet's history and enables us to describe how the density and seismic properties have evolved over time. We calculated the …

Snow Accumulation and Melt Timing at High Elevations in Northwest Montana
The sensitivity of snowmelt driven water supply to climate variability and change is difficult to assess in the mountain west, where strong climatic gradients coupled with complex topography are sampled by sparse ground measurements. We developed a snowmelt model, which ingests daily satellite …

The hydrology of debris-covered glaciers
… Alps. The supraglacial hydrology was studied by modelling ablation using a distributed energy balance melt model, and measuring supraglacial stream discharges; the structure and evolution of the englacial and subglacial network was investigated using dye tracing and water chemistry monitoring; …

Quantifying glacier melt enhancement due to dust deposition during the 2022 melt season. Tungnaárjökull glacier, South Iceland
… investigate the impact of the dust event on the melt season SMB, this study used automatic weather station (AWS) data from three different sites on Tungnaárjökull glacier, a SW-outlet of Vatnajökull ice cap. Daily melt was estimated with a simple snow-melt model and AWS data. To quantify the …

Changes in surging outlet glaciers of the Langjökull Ice Cap, Iceland
… ice cap, Iceland. It utilises digital elevation models from 1986, 1997, 2004 and 2007 in order to assess topographic change. These changes are linked to the surging outlets in terms of alteration of the subglacial hydrological system. Flux of water through the subglacial system is considered …

Evaluating and correcting sensor change artifacts in the SNOTEL temperature records, southern Rocky Mountains, Colorado
… a simple temperature index snow accumulation and melt model. Results show that the significant warming trends found in the original datasets, especially in minimum temperature (average increase of 1.2 °C per decade), decreased (to an average of 0.5 °C per decade) after homogenization. Step-like …

Modelling the Hydrology of the Greenland Ice Sheet
… analysis of surface velocity measurements, or modelled in a theoretical, idealised way. This study focuses on the development of a high spatial (100 m) and temporal (1 hour) resolution, physically based, time-dependent hydrological model which is applied to the ~2,300 km2 Paakitsoq region, West …

Evolving subglacial water systems in East Antarctica from airborne radar sounding
… downstream from the destination lakes. Hydraulic modeling work indicates that the initial release of water from the source lake could have been accommodated by a self-enlarging semicircular channel. Subsequent evolution of the discharge and the three-month delay between release of water from the …
