Snow depth sensor measurement data for Alpine site, 2010 - ongoing.

This comma delimited file contains hourly snow depth measurements collected using Judd snow depth sensors for water year 2010-2012 (1 October 2009 – 30 September 2012) at the Alpine site, located just southwest of the Tundra Lab in the Niwot Ridge Long-Term Ecological Research (NWTLTER) project area. The file contains both level 0 and level 1 (see details in “Process Description” below) hourly snow depth data measured in centimeters, and an accompanying metadata file. The README file contains descriptive details about all files included in the data release. Datasets available in this series include measurements for 3 sites-Alpine, Upper Subalpine (USA) and Lower Subalpine (LSA)- consisting of data for 14 sensors at the Alpine site, 13 sensors at the USA site, and 15 sensors at the LSA site, for a total of 42 sensors at the 3 sites. Elevation ranges from 3060m at LSA to 3550m at the Alpine site.

该逗号分隔符文件包含2010-2012水文年（即2009年10月1日至2012年9月30日）的逐小时雪深观测数据，此类数据由贾德雪深传感器（Judd snow depth sensors）采集，观测点位为阿尔卑斯站点，该站点位于尼沃特岭长期生态研究（NWTLTER）项目区内苔原实验室西南侧。本文件包含以厘米为单位的0级和1级逐小时雪深数据（详细说明见下文“处理流程说明”），并附带元数据文件。本数据发布包中所有文件的详细说明均收录于README文档中。本系列数据集涵盖3个观测站点的观测数据——阿尔卑斯站点、高海拔亚高山带（USA）站点以及低海拔亚高山带（LSA）站点：阿尔卑斯站点布设14台传感器，USA站点布设13台传感器，LSA站点布设15台传感器，三个站点总计42台传感器。各站点海拔范围为LSA站点的3060米至阿尔卑斯站点的3550米。
