Surface Mass Balance and Snow Depth on Sea Ice Working Group (SUMup) 10 meter borehole temperature subdataset, Greenland and Antarctica, 1957-2017

This dataset currently contains 761 ten meter borehole temperatures across Greenland and Antarctica. These measurements were taken either from individual boreholes or during traverses. This dataset is a compilation of work from many individual researchers. When using this dataset please cite both the individual researchers who provided the data as listed in the Citation field as well as this dataset. Much of this data was originally in Antarctic Ice Temperature Data (THERMAP), a National Snow and Ice Data Center (NSIDC) funded project of temperature data that is no longer available. The measurement methods include Thermohm and Wheatstone bridges, Leeds and Northrup 4735 guarded Wheatstone bridge and a 9834 null detectors, Leeds and Northrup thermohms, Thermister thermometers, Mercury-iridium thermometers, Glass-bead thermistor and a Direct Current (D.C.) Wheatstone's Bridges, and RST ThermArrays. The majority of the measurements (greater than 99%) are from Antarctica with few from Greenland, though this will be updated on an annual basis to include more measurements from both the Arctic and Antarctic. Fields of the data include Date Taken, Latitude, Longitude, Depth Taken, Borehole Temperature, Error, Delta Time, Length of Measurement, elevation, method, name, and citation.

本数据集目前收录格陵兰与南极洲共计761组10米深度钻孔温度测量数据。这些测量数据既采集自独立钻孔，也来源于野外横穿科考活动。本数据集由多位独立研究者的工作成果汇编整合而成。使用本数据集时，请同时引用【引用字段】中列明的提供数据的研究者，以及本数据集本身。其中绝大多数数据最初收录于《南极冰温数据集（Antarctic Ice Temperature Data, THERMAP）》——该项目曾由美国国家冰雪数据中心（National Snow and Ice Data Center, NSIDC）资助，目前已无法公开获取。本次数据采用的测量方法包括：热欧姆测温仪（Thermohm）与惠斯通电桥、利兹与诺斯罗普4735型防护式惠斯通电桥及9834型零点检测器、利兹与诺斯罗普热欧姆测温仪、热敏电阻温度计（Thermister thermometers）、汞铱温度计、玻璃珠热敏电阻、直流（D.C.）惠斯通电桥，以及RST热敏阵列（RST ThermArrays）。数据集收录的测量数据中，超过99%来源于南极洲，仅少量来自格陵兰；本数据集将按年度进行更新，补充更多南北极地区的测量数据。数据集包含以下字段：采集日期、纬度、经度、采集深度、钻孔温度、测量误差、时间增量、测量时长、海拔、测量方法、样本名称及引用信息。
