Short summary
This research presents China's first long-term (1981–2023) hyperspectral ultraviolet radiation dataset with exceptional 0.5 nm spectral resolution. The spectral detail enables precise identification of UV absorption characteristics and atmospheric interactions previously obscured in conventional broadband measurements. These results provide new capabilities for monitoring ozone depletion, and optimizing solar energy systems across China's diverse climatic regions.
