TL;DR: In this article, a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts is described. But despite the diversity of the participants (230 scientists in total), the process revealed much about community priorities and the state of our science: a preference for continuity in research questions rather than radical departures or redirections from past and current work.

TL;DR: In this paper, the authors provide an overview on the current knowledge on snow, glacier, and permafrost processes, as well as their past, current, and future evolution.

TL;DR: In this article, an enhanced temperature-index glacier melt model, incorporating incoming shortwave radiation and albedo, is presented, which is an attempt to combine the high temporal resolution and accuracy of physically based melt models with the lower data requirements and computational simplicity of empirical melt models, represented by the degree-day method and its variants.

TL;DR: In this article, three snowpack models of varying complexity and purpose were evaluated across a wide range of hydrometeorological and forest canopy conditions at five Northern Hemisphere locations, for up to three months.

TL;DR: In this paper, the authors focus on the impact of model complexity on the energy-budget components of a snow energy-model and evaluate different albedo parameterizations for different snowpack states (in winter and spring).
