Simulation of Arctic snow microwave emission in surface-sensitive atmosphere channels [PDF]

The Cryosphere
Accurate simulations of snow emission in surface-sensitive microwave channels are needed to separate snow from atmospheric information essential for numerical weather prediction.

Analysis of QualitySpec Trek Reflectance from Vertical Profiles of Taiga Snowpack

Geosciences, 2018
Snow microstructure is an important factor for microwave and optical remote sensing of snow. One parameter used to describe it is the specific surface area (SSA), which is defined as the surface-area-to-mass ratio of snow grains.

Tower-based C-band radar measurements of an alpine snowpack [PDF]

The Cryosphere
To better understand the interactions between C-band radar waves and snow, a tower-based experiment was set up in the Idaho Rocky Mountains for the period of 2021–2023.

Retrieval of Effective Correlation Length and Snow Water Equivalent from Radar and Passive Microwave Measurements

Remote Sensing, 2018
Current methods for retrieving SWE (snow water equivalent) from space rely on passive microwave sensors. Observations are limited by poor spatial resolution, ambiguities related to separation of snow microstructural properties from the total snow mass ...

Description of the snow microstructure as a 3D assembly of grains

, 2013
The concept of snow grain is commonly used in the snow community, either in situ to identify the snow type or in numerical models to reproduce the physical and mechanical behaviour of the snowpack. Among all possible definitions of grains (optical, crystalline and mechanical), we consider mechanical grains as particles separated by potential stress ...
