ICECAPS-MELT: Manual snow density from two 1-m snow profiles in southwest Greenland (May 2024)
Abstract
Manual snow density (km m-3) from two 1-m deep snow profile 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. Manual snow density was measured using American Avalanche Association classifications and procedures (Snow, Weather, and Avalanche Guidelines, 4th Edition, 2022). 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: |
The mass of each snow sample was recorded in the field. The metal cutter volume was measured independent of manufacturer specifications. All computations were made away from deep field conditions. Density was computed as the mass (+/- 0.1 g, 1-sigma) divided by the volume (small cutter uncertainty = +/- 4 cm3, 1-sigma; large cutter uncertainty = +/- 10 cm3). |
| Data Quality: |
Manual snow density measurements were made using American Avalanche Association standards from Snow, Weather, and Avalanche Guidelines, 4th Edition, 2022. They were cross-referenced against concurrent permittivity-based snow density measurements.
