Soil moisture and snowdepth measurements in the Black Sand experiment for East Knoll, Audubon, Lefty, Soddie and Trough, 2018 - 2023.

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.

黑砂试验（Black Sand Experiment）的研究目标为测定其在尼沃特岭（Niwot Ridge）上对融雪日期的处理效应。作为延长夏季研究计划的组成部分，研究团队在尼沃特岭全域布设了5处配备配对样地（处理组与对照组）的试验点，以探究提前融雪所产生的影响。本数据集涵盖融雪季全程的雪深观测数据，以及用于指示融雪时间的人工采集的体积含水量与温度观测数据。
