ICECAPS-MELT: Snow specific surface area from two 1-m snow profiles in SW Greenland (May 2024)
Abstract
Snow specific surface area (SSA, m2/m3) was measured using an active near-infrared sensor (FPGA Company Infrasnow) from 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 SSA 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 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 Infrasnow 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 Infrasnow User Manual. Some spatial variability was apparent in snow properties based on unpublished compression strength measurements. Unevenness in the snow pit face will allow a variable but small amount of side-light into the measurement causing a variable but small low bias in these measurements.
