Microstructural analytical techniques for snow compacted by an aircraft tire
Tribology International, 2007Abstract Assessing the frictional condition of snow-contaminated runways is difficult and requires an understanding of the tribological processes during the tire–snow–pavement interaction. Hence, analytical techniques to study the snow after the interaction are desired.

Changes in Microstructural Parameters of Snow during Deformation.
1994Abstract : This study utilized quantitative and morphology theory to describe the microstructure of cohesive granular materials and to relate microstructure to mechanical and physical properties. Snow was used as the experimental material. A unique feature of the theory developed in this grant involved the description of the necked areas which are the ...

Snow Microstructure over Antarctic Landfast Ice
Landfast ice plays a significant role in climate and ecosystems in Antarctic coastal regions. From October to December 2022, we investigated the physical properties of snow and sea ice on Antarctic landfast ice in McMurdo Sound, following the protocols from the MSOAiC expedition. Our measurements confirmed some findings from MOSAiC (e.g.Ruzica Dadic +9 more

Optical Determination of Snow Microstructure Parameters with the SnowImager instrument
Extensive and reliable ground-truth measurements of snow properties play a crucial role in environmental science to validate models and remote-sensing products. Among the available methods, optics-based approaches offer a good compromise between measurement accuracy and sufficiently large coverage.We present the technical details of the SnowImager as ...Adrian Zölly +5 more

Influence of snow microstructure on the compressive strength of weak layers
Slab avalanches result from the failure of a weak snowpack layer buried underneath a cohesive slab. Determining the material properties of different weak layer morphologies is therefore necessary to better understand and model slab avalanche formation.Jakob Schöttner +7 more
