Revisiting Snow Water Equivalent Bias in the Noah‐MP Land Surface Model in the Western U.S.
Abstract Land surface models (LSMs) are widely used to generate snow records, forecasts, and projections that support water research and management. The complex sources of uncertainty in LSMs motivate evaluations to better understand bias characteristics and identify underlying causes that guide model development.

Assessing the catastrophic break-up of Briksdalsbreen, Norway, associated with rapid climate change
Recent research has raised concerns about the potential influence of rapid climate change on the stability of major ice sheets. The behaviour of glaciers is determined largely by the processes and conditions operating at their base.

Breakthrough in Measuring Snowfall Intensity With Hybrid Deep Learning and Surveillance Cameras
Abstract Accurate snowfall measurements are vital for disaster mitigation, climate studies, and many other applications. Widely deployed surveillance cameras offer novel possibilities for fine‐scale snowfall observation. This paper proposes HySnowNet, a hybrid framework that first extracts snowflakes using physical frequency domain techniques, then ...

Radio-echo soundings on Icelandic temperate glaciers: history of techniques and findings [PDF]
Publisher's version (útgefin grein)Since the mid-1970s radio-echo soundings have been conducted on Iceland's temperate glaciers. Since then, low-frequency radar technology has furthered the study of most of the island's ice caps. Their masses and volumes

Characterizing the subglacial environment of lower Thwaites Glacier using radar modeling
Understanding the spatial heterogeneity beneath Thwaites Glacier, West Antarctica, is vital to projecting its impact on future sea levels. Radar-echo sounding (RES) is commonly used to infer subglacial conditions, but these data can be challenging to ...

The Energy Balance Behind Glacier Retreat: A Regional Reconstruction for Western Canada (1980–2022)
Abstract Glacier mass loss has accelerated globally in recent decades, yet many regional and global glacier models still rely on temperature‐index melt approaches that limit physical realism and process attribution. Here, we apply a glacier evolution model incorporating a physically based surface energy balance (SEB) melt component to reconstruct ...

DJ4Earth: Differentiable, and Performance‐Portable Earth System Modeling via Program Transformations
Abstract Differentiable Earth system models (ESMs) enable powerful applications such as sensitivity analysis, gradient‐based calibration, state estimation, boundary flux inversions, uncertainty quantification, and online machine learning. Reverse‐mode automatic differentiation (AD) efficiently provides gradients for such tasks, yet models have rarely ...
