ICECAPS-MELT: Manual snow properties from two 1-m snow profiles in SW Greenland (May 2024)
Abstract
Snow properties were measured in two 1-m deep snow profiles from southwest Greenland (Camp Raven, 66.48 N, 46.30 W, 2331 m asl) during Spring 2024. The snow profile measurements were made adjacent to an autonomous atmospheric and glaciological platform (the SLEIGH) as part of the ICECAPS-MELT (Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation - MEasurements along Lagrangian Transects) experiment. A layer identification was performed and then snow properties were measured: snow grain size, snow crystal habit/form, and hand hardness. Profile 1 was measured on 15 May 2024, 2-3 meters from the eventual SLEIGH installation. Profile 2 was measured on 18 May 2024, 20 m from the eventual SLEIGH installation.
This work was US-led, US-UK collaboration co-funded by the US National Science Foundation and the UK National Environment Research Council.

| Data lineage: |
Manual snow property measurements of snow grain size, snow crystal habit/form, and hand hardness were made using American Avalanche Association standards from Snow, Weather, and Avalanche Guidelines, 4th Edition, 2022. Snow grains > 0.5 mm were recorded to the nearest 0.5 mm, otherwise very fine grains recorded as 0.1, 0.3, 0.5 mm. The layer identification was done by sliding a snow crystal card downward through the snow pit face to test for changes in tensile strength. These layers were cross-checked against the visual appearance of each layer. The hand hardness classifications were converted to a 0-5 scale, with 0.5 increments allowed when the snow was determined to be in between two classifications. |
| Data Quality: |
Some spatial variability was apparent in snow properties based on unpublished compression strength measurements. Layer ID has vertical resolution of +/- 0.5 cm (1-sigma). Snow grains > 0.5 mm in diameter were recorded to the nearest 0.5 mm, otherwise very fine grains recorded as 0.1, 0.3, or 0.5 mm.
