Estimating snow cover from publicly available images [PDF]

, 2015
In this paper we study the problem of estimating snow cover in mountainous regions, that is, the spatial extent of the earth surface covered by snow. We argue that publicly available visual content, in the form of user generated photographs and image ...

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).

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 (

Evaluation of snow depth and snow cover over the Tibetan Plateau in global reanalyses using in situ and satellite remote sensing observations

The Cryosphere, 2019
. The Tibetan Plateau (TP) region, often referred to as the Third Pole, is the world's highest plateau and exerts a considerable influence on regional and global climate.

From research to national expansion: 20 years' experience of community-based management of childhood pneumonia in Nepal

Bulletin of the World Health Organization
PROBLEM: Pneumonia is a leading cause of mortality of children aged under five in Nepal. Research conducted by John Snow Inc. in the 1980s determined that pneumonia case management by community-based workers decreased under-five mortality by 28 ...

Micromechanical modeling of snow failure [PDF]

The Cryosphere, 2020
Dry-snow slab avalanches start with the formation of a local failure in a highly porous weak layer underlying a cohesive snow slab. If followed by rapid crack propagation within the weak layer and finally a tensile fracture through the slab, a slab ...
