Snow depth variability in the Northern Hemisphere mountains observed from space
Nature Communications, 2019 Accurate snow depth observations are critical to assess water resources. More than a billion people rely on water from snow, most of which originates in the Northern Hemisphere mountain ranges.

Global snow drought hot spots and characteristics
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Given the importance of snow to global food, water, and energy security, characterizing snow deficits (snow droughts) in a changing climate has emerged as a critical knowledge gap. We identify snow drought hot spots and determine how drought

Prediction of natural dry-snow avalanche activity using physics-based snowpack simulations [PDF]
Natural Hazards and Earth System Sciences, 2023 Predicting the timing and size of natural snow avalanches is crucial for local and regional decision makers but remains one of the major challenges in avalanche forecasting.

A Lagrangian Snow‐Evolution System for Sea‐Ice Applications (SnowModel‐LG): Part I—Model Description
Journal of Geophysical Research - Oceans, 2020 A Lagrangian snow‐evolution model (SnowModel‐LG) was used to produce daily, pan‐Arctic, snow‐on‐sea‐ice, snow property distributions on a 25 × 25‐km grid, from 1 August 1980 through 31 July 2018 (38 years).

Micro-mechanical insights into the dynamics of crack propagation in snow fracture experiments
Scientific Reports, 2021 Dry-snow slab avalanches result from crack propagation in a highly porous weak layer buried within a stratified and metastable snowpack. While our understanding of slab avalanche mechanisms improved with recent experimental and numerical advances ...

Reconstruction of four-dimensional rockfall trajectories using remote sensing and rock-based accelerometers and gyroscopes [PDF]
Earth Surface Dynamics, 2019 This work focuses on the in-depth reconstruction of the full set of parameters of interest in single-block rockfall trajectories. A comprehensive understanding of rockfall trajectories holds the promise to enhance the application of numerical models for ...

Spatial variation of the rain–snow temperature threshold across the Northern Hemisphere
Nature Communications, 2018 Despite the importance of precipitation phase to global hydroclimate simulations, many land surface models use spatially uniform air temperature thresholds to partition rain and snow. Here we show, through the analysis of a 29-year observational dataset (
