Updated Meteorological, Radiation, and Soil Temperature Data, Kuparuk River and Nearby Watersheds: Lower Kuparuk (LK) station, 1992-1995.

The data files in this data set contain climate information from sites on the North Slope of Alaska in or near the Kuparuk River basin. The data was collected for a hydrologic study of rivers in the North Slope region between 1985-present. Hydro-meteorological stations were established at various locations throughout the Kuparuk, but also in the Putuligayuk and Sagavanirktok watersheds. The variables collected at most stations were air temperature, humidity, wind speed and direction, soil temperature, snow temperature, precipitation, snow depth, and radiation. In the Kuparuk watershed, the Lower Kuparuk (LK) Coastal Plain meteorological station operated from 1992-1995. IMPORTANT NOTE: Updates and corrections were made to the original datasets by the investigators, and all of the previously published data files should be replaced with this updated dataset. The following corrections were made to the datasets originally published in 2008 and 2010 (data collected 1985-2008): 1) data from annual .csv files were merged into one .csv file (for each station) containing all years of data, 2) appended new data collected from 2008 to 2018 into the .csv file 3) standardized file headers, 4) standardized variable names, units, and sensor installation height above ground surface 5) reviewed all data for quality assurance and added qualifiers to erroneous data, 6) added a data qualifier to wind data during periods of extensive riming on wind sensors, 7) added a qualifier when air temperatures are below -39 degrees Celsius (C) (minimum reporting temperature of some air temperature sensors), and 8) removed duplicative data and fixed timestamp issues.

本数据集的数据文件包含阿拉斯加北坡库帕鲁克河（Kuparuk River）盆地内及周边站点的气候信息。该数据为1985年至今针对北坡地区河流水文研究所采集。研究团队在库帕鲁克流域全域及普图利加尤克（Putuligayuk）、萨加万尼克托克（Sagavanirktok）流域的多处点位布设了水文气象站。多数站点采集的变量涵盖气温、湿度、风速、风向、土壤温度、积雪温度、降水量、积雪深度与辐射量。其中库帕鲁克流域的下库帕鲁克（LK）沿海平原气象站运行时段为1992年至1995年。

重要说明：研究人员已对原始数据集完成更新与修正，所有此前发布的数据文件均需替换为本更新后的数据集。针对2008年与2010年发布的原始数据集（数据采集时段为1985-2008年），本次修正内容如下：
1. 将各站点的年度.csv格式文件合并为单份包含全时段数据的.csv文件；
2. 将2008年至2018年采集的新增数据追加至上述.csv文件中；
3. 统一文件表头格式；
4. 统一变量名称、单位以及传感器距地面的安装高度；
5. 开展全量数据质量审查，为异常数据添加质控标识；
6. 为风速传感器发生严重结霜时段的风速数据添加质控标识；
7. 为气温低于-39摄氏度（℃）的记录添加标识——该阈值为部分气温传感器的最低可报告温度；
8. 删除重复数据并修复时间戳问题。
