AB  - This dataset is a high-precision precipitation benchmark dataset in the upper reaches of Danjiangkou Reservoir in the Hanjiang River Basin from 1980 to 2020. It is constructed using a UNet deep learning model improved based on the CBAM attention mechanism and belongs to a precipitation fusion product. The dataset integrates the station observation precipitation data of the China regional surface meteorological element-driven dataset CN05.1 and the ERA5 global reanalysis precipitation grid data, fully combining the accuracy advantages of ground station observations with the spatial coverage integrity of reanalysis products.The data set completely covers the 40-year long time series. The CBAM-UNet model effectively mines the spatial structure characteristics and local change laws of the precipitation field. The spatio-temporal resolution of the data can meet the actual needs of refined hydrological simulation of the river basin.Contains monthly high-precision precipitation data in the basin from 1980 to 2020 (0.1°*0.1°).
