Description
Summary:The SnowMicroPen (SMP) is a portable device for high-resolution in-situ measurements of penetration resistance in snow and can be correlated to snow microstructure (density, specific surface area, snow type). The penetration force is measured using a piezo-electric sensor and is digitally recorded every 4 micrometers. The SMP signal can infer stratigraphy, snow type, and snow microstructure at a vertical resolution of 1-4 mm. Based on the force signal, density and specific surface area parameterizations are calculated. Through horizontally repeated measurements, the SMP can help relate detailed point-scale snow profiles to a larger sampling area and provide information about the spatial variability of snow stratigraphy and physical snow properties. During the MOSAiC expedition (October 2019-September 2020), the SMP was used to measure 389 snowpits or transects to allow for upscaling of detailed point measurements of snow profiles. This dataset consists of 6837 SMP measurements and covers a complete annual ...
