Seasonal soil temperatures from a Circumarctic Active Layer Monitoring (CALM) grid, Barrow, Alaska, 2016

Seasonal soil temperature measurements were collected during the 2016 growing season at each Circumarctic Active Layer Monitoring (CALM) grid subset plot (30) in Utqiaġvik (formerly Barrow), Alaska. At each plot one temperature measurement was acquired, the date, start and end times, and the people present were also recorded. Soil temperature measurements were taken outside of every plot on the northeastern most corner in order to reduce disturbance of vegetation. These measurements are part of the Arctic Observing Network (AON) - International Tundra Experiment (ITEX) initiative and help to document seasonal changes in surface moisture and structure at high spatial scales.

2016年生长季期间，研究人员于阿拉斯加州乌特恰维克（Utqiagvik，旧称巴罗）的环北极活动层监测（Circumarctic Active Layer Monitoring, CALM）网格的30个子样地中采集季节性土壤温度数据。每个样地均完成一次土壤温度测量，同时记录测量日期、起止时刻及在场人员信息。为降低对植被的干扰，所有土壤温度测量点位均布置在每个样地的东北最外侧外缘区域。本批测量数据隶属于北极观测网（Arctic Observing Network, AON）-国际冻原实验（International Tundra Experiment, ITEX）计划，可用于表征高空间尺度下的地表湿度与表层结构的季节变化特征。
