AB  - The Tianshan Mountains, one of the world's seven major mountain systems, are the farthest mountain range from any ocean and represent a typical alpine region in China. Known as the "Water Tower of Central Asia," this area holds strategic significance for Xinjiang and Central Asia. With advancements in remote sensing technology, satellite-derived precipitation has become a key tool for estimating mountainous precipitation. However, complex and heterogeneous terrain in mountainous regions leads to low accuracy in satellite precipitation retrieval products. To address this, this study developed a multi-source precipitation fusion dataset for the Tianshan Mountains. Using GSMaP satellite precipitation data as the initial field and incorporating ground-truth precipitation data from 1,065 regional stations, we developed an optimal interpolation-based fusion method for satellite-ground precipitation products, ultimately generating a daily precipitation dataset for the Tianshan Mountains (2000-2022). During development, strict quality control was applied to ground data, and daily fused precipitation data underwent rigorous evaluation. This dataset is expected to support water resource management and efficient utilization in complex terrain regions.
