A dataset of annual TCI, VCI, VHI and TVDI with the resolution of 1 km in the Yellow River Basin (2003–2022)

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.

黄河流域主要分布于干旱、半干旱气候区，天然水资源禀赋匮乏，是我国主要流域中受干旱影响最为严重的流域。随着全球环境与气候变化持续演进，黄河流域干旱事件愈发频发，使得干旱监测研究成为当前的研究热点。本数据集以MODIS植被数据与地表温度产品为基础，通过去云、数据重构等质量控制流程，整理得到2003—2022年黄河流域逐年温度条件指数（Temperature Condition Index, TCI）、植被状态指数（Vegetation Condition Index, VCI）、植被健康指数（Vegetation Health Index, VHI）与温度植被干旱指数（Temperature Vegetation Dryness Index, TVDI）数据。本数据集的空间范围为北纬32°10′—41°50′、东经95°53′—119°05′。数据集采用GeoTiff格式存储，空间分辨率为1km。可为黄河流域干旱灾害监测提供基础数据与科学支撑。
