A magnitude-7.5 earthquake struck western Colombia on Aug. 10, 2026, causing widespread damage across 32 cities. According to figures released by local authorities on Aug. 15, the death toll had risen to 294, with 3,935 people injured.

Researchers from the Aerospace Information Research Institute, Chinese Academy of Sciences; Sichuan University of Science and Engineering; and the Institute of Atmospheric Physics, Chinese Academy of Sciences, reported the study in the Journal of Remote Sensing​ on April 29, 2026. The article presents a new satellite-based method for retrieving global, direct, and diffuse solar radiation from FY-4A. The work targets a key operational problem: how to deliver accurate sunlight estimates at high spatiotemporal resolution without relying heavily on dense ground observations or auxiliary atmospheric datasets.

Researchers from 16 Chinese institutions, including the Aerospace Information Research Institute of the Chinese Academy of Sciences (AIRCAS), Beijing Normal University, Peking University, Sun Yat-sen University, and Tsinghua University, published the editorial in the Journal of Remote Sensing​. The article addresses the limitations of fragmented, static, and largely offline observation systems by defining scientific and technical priorities for real-time, cross-platform, and intelligent remote sensing services in climate monitoring, ecological assessment, emergency management, and planetary exploration worldwide today.
