2012-2014年中国黑河中游BNUNET土壤湿度观测数据集

本数据集包括黑河中游张掖市周边的扁都口地区0.5°×0.5°观测矩阵内26个BNUNET节点的2013年9月—2014年3月（时间标准：北京时间，UTC+8）连续观测数据集。26个节点配置均相同，包含1cm、5cm和10cm深度的3层土壤温度探头和5cm深度的1层土壤水分探头，观测频率为2小时。本数据集可为地表异质性的遥感真实性检验、生态水文等研究提供时空连续的观测数据集。

This dataset contains continuous observation data from 26 BNUNET nodes within a 0.5°×0.5° observation matrix in the Biandukou area around Zhangye City, middle reaches of the Heihe River, spanning the period from September 2013 to March 2014 (time standard: Beijing Time, UTC+8). All 26 nodes share identical configurations, which are equipped with 3 layers of soil temperature probes at depths of 1 cm, 5 cm and 10 cm, and 1 layer of soil moisture probe at 5 cm depth, with an observation frequency of once every 2 hours. This dataset can provide spatio-temporally continuous observation data for studies such as remote sensing validation of surface heterogeneity, ecohydrology and related research.
