Multitemporal analysis of Sentinel-1 backscatter during snowmelt using high-resolution field measurements and radiative transfer modelling [PDF]

open access: yesThe Cryosphere
The spatiotemporal evolution of snowmelt is fundamental for water resources management and risk mitigation in mountain catchments. Synthetic aperture radar (SAR) images acquired by satellite systems such as Sentinel-1 (S1) are promising for monitoring ...

The causal effect of agricultural landscape simplification on Germany's grasslands during a compound drought and heatwave in 2018

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Preserving ecosystem services, along with economic and environmental benefits, will require future landscape policies to identify and incorporate relevant landscape features. In this paper, we investigate the causal effect of agricultural landscape simplification on drought‐related grassland damages.

Wet Snow Detection From Satellite SAR Images by Machine Learning With Physical Snowpack Model Labeling

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The detection of wet snow by satellite imaging is currently done in an unsupervised way and lacks quantitative evaluation due to the difficulty of collecting ground truths in extreme environments.

Impact of climate change on snow avalanche activity in the Swiss Alps [PDF]

open access: yesThe Cryosphere
The cryosphere in mountain regions is rapidly transforming due to climate change, yet the impact of these changes on snow avalanche activity remains uncertain.

Perlite is a suitable model material for experiments investigating breathing in high density snow

open access: yesScientific Reports, 2022
Outdoor breathing trials with simulated avalanche snow are fundamental for the research of the gas exchange under avalanche snow, which supports the development of the international resuscitation guidelines.

CNN Classification of Wet Snow by Physical Snowpack Model Labeling

open access: yesIGARSS 2023 - 2023 IEEE International Geoscience and Remote Sensing Symposium, 2023
We propose a new approach for wet snow extent mapping in Synthetic Aperture Radar (SAR) images by using a convolutional neural network (CNN) designed to learn with respect to snowpack outputs from the state-of-the-art snow model Crocus. The CNN was trained to classify the wet snow conditions based on features extracted from the SAR images, using both ...

Biographies, ontological security and the socio‐spatial politics shaping teachers' mobility in remote Australia

open access: yesBritish Educational Research Journal, EarlyView.
Abstract The global teacher shortage continues to intensify, with disparate impacts across geographic and socio‐economic communities. In Queensland, Australia, where this study originates, post‐COVID teacher shortages have intensified workforce pressures, leaving several regional, rural and remote schools as some of the ‘hardest‐to‐staff’ in the ...

Implementation of a physically based water percolation routine in the Crocus/SURFEX (V7.3) snowpack model [PDF]

open access: yesGeoscientific Model Development, 2017
We present a new water percolation routine added to the one-dimensional snowpack model Crocus as an alternative to the empirical bucket routine. This routine solves the Richards equation, which describes flow of water through unsaturated porous snow ...

Soil erosion in an avalanche release site (Valle d'Aosta: Italy): towards a winter factor for RUSLE in the Alps [PDF]

open access: yes, 2014
Soil erosion in Alpine areas is mainly related to extreme topographic and weather conditions. Although different methods of assessing soil erosion exist, the knowledge of erosive forces of the snow cover needs more investigation in order to allow soil ...
