ICECAPS-MELT: Permittivity-based snow density from a 1-m snow profile in SW Greenland (August 2024)
Abstract
Snow density (kg m-3) was measured using two different permittivity-based devices (FPGA Company SnowPro-40 and SnowPro-17 sensors) from a 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. 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 SnowPro-40 permittivity sensor was inserted vertically into a slot the snow pit wall, then moved vertically downwards for each subsequent measurement. The SnowPro-17 permittivity sensor was held vertically against the snow pit wall, then moved vertically downwards for each subsequent measurement. These sensors were calibrated by the manufacturer and delivered with appropriate calibration coefficients. Calibrations were applied after data were collected in the field. |
| Data Quality: |
All measurements were made in alignment with FPGA SnowPro User Manual, v2. Some spatial variability was apparent in snow properties based on unpublished compression strength measurements. There may have been air gaps between the SnowPro-17 and the snow pit face, resulting in a small low bias in these measurements. Measurements were made only in dry snow.
