Continuous and autonomous snow water equivalent measurements by a cosmic ray sensor on an alpine glacier

, 2019
. Snow water equivalent (SWE) measurements of seasonal snowpack are crucial in many research fields. Yet accurate measurements at a high temporal resolution are difficult to obtain in high mountain regions.

Using time‐series remote sensing to identify and track individual bird nests at large scales

Remote Sensing in Ecology and Conservation, EarlyView.
Time‐series airborne imagery can potentially track individuals over time to collect information beyond one‐off counts. Using weekly UAS‐based imagery of wading bird colonies, we develop an automated approach to identifying nests. Our algorithmic approach detected 68–74% of known nests and exhibited similar performance to human review of imagery ...

Constraining Kilometer‐Scale Mountain Snow Transport and Snowshed Areas

Geophysical Research Letters
Snow transport (wind drifting and avalanches) can concentrate a large amount of water into a relatively small area, in contrast to precipitation, which is spatially smoother.

Spatial Variability of Snow Water Equivalent – The Case Study from the Research Site in Khibiny Mountains, Russia

Journal of Hydrology and Hydromechanics, 2019
The aim of the investigation was assessment of spatial variability of the characteristics of snowpack, including the snow water equivalent (SWE) as the main hydrological characteristic of a seasonal snow cover.

High resolution spatial variability in spring snowmelt for an Arctic shrub-tundra watershed [PDF]

, 2019
Arctic tundra environments are characterized by spatially heterogeneous end-of-winter snow cover because of high winds that erode, transport and deposit snow over the winter.

Students’ Experiences of Teachers’ Ways of Unpacking Visual Representations in the Context of Intermolecular Forces

Science Education, EarlyView.
ABSTRACT This is the third article in a series, emanating from a project that used social semiotics and phenomenography to explore the role visual representations play in the teaching and learning of chemistry. Building on our earlier work that identified five qualitatively different ways that teachers may use to unpack visual representations in their ...

Analyzing Machine Learning Predictions of Passive Microwave Brightness Temperature Spectral Difference Over Snow-Covered Terrain in High Mountain Asia [PDF]

Snow is an important component of the terrestrial freshwater budget in high mountainAsia (HMA) and contributes to the runoff in Himalayan rivers through snowmelt. Despitethe importance of snow in HMA, considerable spatiotemporal uncertainty exists across

Evaluation and Intercomparison of Multiple Snow Water Equivalent Products over the Tibetan Plateau

Journal of Hydrometeorology, 2019
Snow cover affects the thermal conditions of the Tibetan Plateau through snow–albedo feedback and snowmelt, which, in turn, modulates the Asian summer monsoon climate.
