New Study Reveals Lunar Perspective Enables Accurate Capture of Earth’s Radiation Budget

Editor: LI Yali |  Jan 26, 2026

A research team led by the CAS Institute of Atmospheric Physics (IAP) has demonstrated that lunar observations provide a unique solution to accurately capturing Earth’s outgoing radiation—an essential step in understanding the planet’s radiation budget, which is closely tied to global climate and environmental changes.

Earth’s radiation budget is a core process of the Earth-atmosphere system, but current satellite observations—whether from low-Earth orbit or geostationary platforms—struggle to achieve both temporal continuity and spatial consistency, creating a critical knowledge gap in studying outgoing radiation patterns. Observing Earth from the Moon offers a distinct advantage. From the Moon, Earth appears as a complete disk, allowing to extract planet-scale dominant signals while suppressing small-scale weather noise.
