Time-lapse observation dataset of soil temperature and humidity on the Tibetan Plateau (2008-2016)

This data set comprises the plateau soil moisture and soil temperature observational data based on the Tibetan Plateau, and it is used to quantify the uncertainty of model products of coarse-resolution satellites, soil moisture and soil temperature. The observation data of soil temperature and moisture on the Tibetan Plateau (Tibet-Obs) are from in situ reference networks at four regional scales, which are the Nagqu network of cold and semiarid climate, the Maqu network of cold and humid climate, and the Ali network of cold and arid climate，and Pali network. These networks provided representative coverage of different climates and surface hydrometeorological conditions on the Tibetan Plateau.- Temporal resolution: 1hour- Spatial resolution: point measurement- Measurement accuracy: soil moisture, 0.00001; soil temperature, 0.1 °C; data set size: soil moisture and temperature measurements at nominal depths of 5, 10, 20, 40- Unit: soil moisture, cm ^ 3 cm ^ -3; soil temperature, °C

本数据集囊括了青藏高原的平原土壤湿度与土壤温度观测数据，旨在量化粗分辨率卫星模型产品在土壤湿度与土壤温度方面的不确定性。青藏高原土壤温度与湿度观测数据（西藏观测）源自四个区域尺度的实地参照网络，包括那曲寒冷半干旱气候网络、玛曲寒冷湿润气候网络、阿里寒冷干旱气候网络及帕里网络。这些网络为青藏高原不同气候和地表水文气象条件提供了具有代表性的覆盖范围。时间分辨率：每小时一次；空间分辨率：点测量；测量精度：土壤湿度，0.00001 cm^3/cm^3；土壤温度，0.1 °C；数据集规模：在5、10、20、40等名义深度下的土壤湿度与温度测量；单位：土壤湿度，cm^3/cm^3；土壤温度，°C。
