Soil moisture and snowdepth measurements in the Black Sand experiment for East Knoll, Audubon, Lefty, Soddie and Trough, 2018 - 2024.

The purpose of the Black Sand experiment is to measure treatment
effects on date of snowmelt on Niwot Ridge. Five sites with paired
plots (treatment and control) were implemented across Niwot as part
of the extended summer research program in order to understand the
effects of earlier snowmelt. This dataset contains measurements of
snowdepth throughout the melt season, manual measurements of
volumetric water content and temperature data as an indication of
snowmelt timing.

黑沙实验（Black Sand experiment）旨在评估处理措施对尼沃特岭（Niwot Ridge）融雪日期的影响效应。作为夏季延长研究计划的组成部分，研究团队在尼沃特岭范围内设置了5处配备配对样地（处理组与对照组）的实验点位，以探究提前融雪所产生的效应。本数据集涵盖融雪季全程的雪深观测数据，以及用于表征融雪时间的体积含水量与温度的人工实测数据。
