Hubbard Brook Experimental Forest (USDA Forest Service): Snow Water Measurements, 1955 - present

Snow measurements have been collected approximately
weekly during the winter season using transects adjacent to
the established network of standard rain gages from 1956 to
the present. Maximum snow depth, water content and snow cover
duration data are recorded at points along a transect known
as a “snow course”, which includes 10 points spaced at 2-m
intervals within a designated 0.25 ha area. Data from one
course are averaged for each collection date and snow water
content is scaled up to a whole watershed value. These data were gathered as part of the Hubbard Brook
Ecosystem Study (HBES). The HBES is a collaborative effort at
the Hubbard Brook Experimental Forest, which is operated and
maintained by the USDA Forest Service, Northern Research
Station.

自1956年至今，研究团队于冬季每约一周开展一次积雪观测，观测样带紧邻已布设的标准雨量计网络。沿被称为"积雪样线（snow course）"的样带测点，研究人员会记录最大雪深、积雪含水量与积雪持续时长数据；该样线在划定的0.25公顷区域内设置10个测点，测点间距为2米。每次观测采集的单条样线数据将取平均值，积雪含水量会被缩放至全流域尺度。本数据集隶属于哈伯德布鲁克生态系统研究（Hubbard Brook Ecosystem Study, HBES）。该研究是哈伯德布鲁克实验林的协作研究项目，由美国农业部林务局（USDA Forest Service）北方研究站运营维护。
