摘　　要：黄河流域大部分属于干旱、半干旱气候,先天水资源条件不足,是中国各大流域中受干旱影响最为严重的流域。随着全球环境和气候变化,黄河流域的干旱愈加频繁,对黄河流域的干旱监测研究已经成为当下的热点。本数据集基于MODIS植被和地表温度产品,通过对逐年数据进行去云、重构等质量控制,分别生产了2003–2022年黄河流域逐年的温度条件指数(Temperature Condition Index,TCI)、植被状态指数(Vegetation Condition Index,VCI)、植被健康指数(Vegetation Health Index,VHI)、温度植被干旱指数(Temperature Vegetation Dryness Index,TVDI)数据集。本数据集空间范围为32°10′N–41°50′N,95°53′E–119°05′E,数据格式为Geo Tiff,空间分辨率为1 km。同其他干旱指数数据集相比,本产品可以在逐年时间尺度上表现黄河流域的干旱格局,在时间序列上反映黄河流域干旱变化趋势,为黄河流域干旱灾害监测提供基础数据支撑。Primarily situated in arid and semi-arid climatic zones,characterized by naturally limited water resources,the Yellow River Basin is the most drought-affected among China's major basins.As global environmental and climate change continue to evolve,droughts in the Yellow River Basin have become increasingly frequent,making drought monitoring research a current focal point.Based on MODIS vegetation data and surface temperature products,this dataset undergoes quality control procedures such as cloud removal and data reconstruction to collect the data of annual Temperature Condition Index(TCI),Vegetation Condition Index(VCI),Vegetation Health Index(VHI)and Temperature Vegetation Dryness Index(TVDI)in the Yellow River Basin from 2003 to 2022.The spatial scope of this dataset ranges from 32°10′N–41°50′N,95°53′E–119°05′E.The dataset is in GeoTiff format with a spatial resolution of 1km.It can provide foundational data and scientific support for drought disaster monitoring in the Yellow River Basin.
