ICECAPS-MELT: Manual snow density from one 1-m snow profile in southwest Greenland (August 2024)
Abstract
Manual snow density (km m-3) from a 1-m deep snow profile from southwest Greenland (Camp Raven, 66.48 N, 46.30 W, 2331 m asl) during Summer 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). This profile was made 2-3 m away from the SLEIGH.
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. 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 = +/- 20 cm3, 1-sigma). |
| 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. Some spatial variability was apparent in snow properties based on concurrent, unpublished snow density measurements.
