ICECAPS-MELT: Manual snow density from two 1-m snow profiles in southwest Greenland (May 2024)

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.

本数据集收录了2024年春季格陵兰西南部雷文营地（Camp Raven，北纬66.48°，西经46.30°，海拔2331米）的两组1米深雪剖面的人工雪密度数据，单位为kg·m⁻³（原文疑似笔误，应为千克每立方米）。雪剖面测量工作紧邻自主式大气与冰川学观测平台（SLEIGH）开展，属于ICECAPS-MELT（能量、云、大气状态与降水综合表征——沿拉格朗日断面测量）实验的一部分。本次人工雪密度测量遵循美国雪崩协会（American Avalanche Association）的分类标准与操作流程，依据《雪、天气与雪崩指南（第4版，2022）》执行。1号雪剖面于2024年5月15日完成测量，测点距最终布设的SLEIGH平台2至3米；2号雪剖面于2024年5月18日完成测量，测点距最终布设的SLEIGH平台20米。
