This dataset contains in situ snow measurements recorded as part of Environment and Climate Change Canada's 2018-2019 Trail Valley Creek Snow Experiment (TVC Experiment 18/19). These measurements were collected to evaluate coincident airborne and satellite radar measurements to better understand snow-radar interactions in a tundra environment. The measurements were recorded 50 km north of the town of Inuvik, Northwest Territories around the Trail Valley Creek research station (https://www.trailvalleycreek.ca/). Three periods of measurement took place in November 2018, January 2019, and March 2019 . Measurements and observations were recorded in handwritten snow pit sheets before being transcribed to electronic sheets. The dataset is organized by surveyed site and includes: 1) manual snowpit measurements of the following parameters: Total snow depth, vertical profiles of snow temperature, snow density, stratigraphy and grain size and notes on site characteristics and environmental conditions. 2) distributed ... : All geographic coordinates were recorded with Garmin GPS units using the geographic coordinate system: WGS 84 (EPSG: 4236). There are four type of data files: snow pit sheets, magnaprobe data, SMP-derived snow parameters and raw SMP penetration force profiles. Snow pit sheets and magnaprobe data are provided as Microsoft Excel (.xlsx) files. SMP-derived snow parameters are provided in comma-separated value (.csv) files. The raw SMP force profiles are binary (.pnt) files. A synthesized version of the magnaprobe snow depth data extracted and associated with a specific snow pit was previously published here https://doi.org/10.5281/zenodo.8350643 . ...
