Snow depth sensor measurement data for Alpine site, 2010 - 2015

Effects of infrared heaters on snow accumulation, snowmelt, and snow–atmosphere energy exchange were examined at Niwot Ridge, Colorado (CO). These .zip data files contains hourly snow depth measurements collected using Judd snow depth sensors for water year 2010-2015 (1 October 2009 – 30 September 2015) 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.本研究针对美国科罗拉多州尼沃特岭（Niwot Ridge）开展试验，探究红外加热器对积雪累积、融雪及雪-大气能量交换的影响。本次提供的.zip压缩数据包包含2010至2015水文年（对应时段为2009年10月1日至2015年9月30日）内，于尼沃特岭长期生态研究（Niwot Ridge Long-Term Ecological Research, NWTLTER）项目区苔原实验室西南侧的高山站点，采用贾德雪深传感器（Judd snow depth sensors）采集的逐小时雪深观测数据。该数据包包含以厘米为单位的0级与1级逐小时雪深观测数据（数据分级详情见下文"Process Description"），以及配套的元数据文件。
