Using satellite imagery and machine learning, we created the first Greenland-wide dataset of slush. We found that it covers about three percent of the ice sheet each summer and expands in area and to higher elevations in years of high melt. Slush influences ice sheet mass loss, and our maps help to improve understanding of meltwater processes in a warming climate. 

Glaciers in the Himalaya are rapidly losing ice in response to climate change. We use a representation of mesoscale meteorological variables to force a climate-glacier model that represents important surface processes such as sublimation, avalanching, and the evolution of supraglacial debris. We find that warming air temperatures increase annual precipitation sufficiently to offset half of glacier volume loss by the end of the century compared with simulations forced only by temperature change.

We studied snow processes in the accumulation area of Mera Glacier (central Himalaya, Nepal) by deploying a cosmic ray counting sensor that allows one to track the evolution of snow water equivalent. We suspect significant surface melting, water percolation, and refreezing within the snowpack, which might be missed by traditional mass balance surveys.

This paper introduces the AtsMOS workflow, a new tool for improving weather forecasts in mountainous areas. By combining advanced statistical techniques with local weather data, AtsMOS can provide more accurate predictions of weather conditions. Using data from Mount Everest as an example, AtsMOS has shown promise in better forecasting hazardous weather conditions, making it a valuable tool for communities in mountainous regions and beyond.

This study analyses the basal sliding and the hydrological drainage of Baltoro Glacier, Pakistan. The surface velocity was characterized by a spring speed-up, summer peak, and autumn speed-up. Snow melt has the largest impact on the spring speed-up, summer velocity peak, and the transition from inefficient to efficient drainage. Drainage from supraglacial lakes contributed to the fall speed-up. Increased summer temperatures will intensify the magnitude of meltwater and thus surface velocities.
