High-Resolution (Half-Hourly) Observational Dataset of Solar Spectral Radiation on Typical Bare Soil Surfaces in the Arid and Semi-arid Region of Northwest China

"The Field Experiment of Air-Land Interaction in the Arid Area of Northwest China and the Second Tibetan Plateau Scientific Expedition and Research are at the forefront of scientific observation and research in the arid and semi-arid region of Northwest China and the Tibetan Plateau. The land-atmosphere integrated observation experiment based on the surface processes and environmental changes in the arid and semi-arid region of Northwest China has provided a large amount of valuable data for the study of the mechanism of the land surface processes and land-atmosphere interaction and its impacts in the arid and semi-arid region of Northwest China. This dataset integrates the half-by-half surface solar spectral radiation (ultraviolet radiation, visible radiation, near-infrared radiation) and global radiation observation data on typical bare soil surfaces with the time span of 2010-2020 from Dunhuang Shuangdunzi Desert Gobi Comprehensive Observation and Research Station (DH-Gobi), Dunhuang Mingshashan-Moonya Spring Desert Observation and Research Station (DH-Desert), Pingliang Bare Loess Comprehensive Observation and Research Station (PL-Loess), Dunhuang Shuanghebao Sparse Vegetation Observation and Research Station (DH-SHB), and Dunhuang Laogolding Sparse Vegetation Observation and Research Station (DH-LJK), respectively. These data can be widely used in the characterization of different bands of solar radiation and its albedo on different typical bare soil surfaces in the arid and semi-arid region of Northwest China, the evaluation of remote sensing products and the development of remote sensing inversion algorithms, as well as the evaluation and development of Land Surface Process Model. This dataset contains only the surface solar spectral radiation and total radiation data (RADM_SR), and the naming rule of the data files is: data type_site name_data start date-data end date.csv.中国西北干旱区陆-气相互作用野外观测试验与第二次青藏高原综合科学考察研究，处于中国西北干旱半干旱区及青藏高原科学观测研究的前沿。依托中国西北干旱半干旱区地表过程与环境变化开展的陆-气综合观测试验，为研究中国西北干旱半干旱区地表过程、陆-气相互作用机制及其影响提供了大量宝贵数据。本数据集整合了来自敦煌双墩子荒漠戈壁综合观测研究站（DH-Gobi）、敦煌鸣沙山-月牙泉荒漠观测研究站（DH-Desert）、平凉裸黄土综合观测研究站（PL-Loess）、敦煌双河堡稀疏植被观测研究站（DH-SHB）以及敦煌老金窝稀疏植被观测研究站（DH-LJK）的典型裸土下垫面逐半小时地表太阳光谱辐射（紫外线辐射、可见光辐射、近红外辐射）与总辐射观测数据，时间跨度为2010-2020年。该数据集可广泛应用于中国西北干旱半干旱区不同典型裸土下垫面的太阳辐射各波段特征及其反照率表征、遥感产品评估与遥感反演算法开发，以及陆面过程模型（Land Surface Process Model）的评估与开发。本数据集仅包含地表太阳光谱辐射与总辐射数据（RADM_SR），数据文件命名规则为：数据类型_站点名_数据起始日期-数据终止日期.csv。
