DOI: 10.1002/2017gl074063
Abstract: Digital cone penetration measurements can be used to infer snow mechanical properties, for instance to study snow avalanche formation. The standard interpretation of these measurements is based on statistically inferred micromechanical interactions between snow microstructural… read more here.
