Impact of climate forcing time step in an ice-sheet firn model

The firn layer regulates how an ice sheet responds to atmospheric climate change by modifying how changes in surface temperature, snow accumulation and ablation affect the ice-sheet mass balance. Firn properties are often simulated with a firn densification model. Prior studies h...

High altitude precipitation dynamics using long-term observations in a Himalayan catchment

Abstract. In the Himalayas, the interaction between climate, orography and land cover results in a highly heterogeneous precipitation pattern. Mountain precipitation, being the main driver of the water cycle, ultimately provides water for millions of people downstream. Our curren...
