Spatio-temporal influence of tundra snow properties on Ku-band (17.2 GHz) backscatter [PDF]

, 2015
During the 2010/11 boreal winter, a distributed set of backscatter measurements was collected using a ground-based Ku-band (17.2 GHz) scatterometer system at 26 open tundra sites.

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 (

Strengthening person-centered care through quality improvement: a mixed-methods study examining implementation of the Person-Centered Care Assessment Tool in Zambian health facilities

HIV Research & Clinical Practice
Introduction Person-centered care (PCC) is considered a fundamental approach to address clients’ needs. There is a dearth of data on specific actions that HIV treatment providers identify as priorities to strengthen PCC.

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 ...
