The Lunar Opposition Effect: Dual-mechanism Partitioning and Shallow-regolith Constraints from GaoFen-4 Photometry
The lunar opposition effect (OE) probes shallow regolith structure and multiple-scattering behavior, but its physical interpretation is limited by difficulties separating shadow-hiding (SHOE) and coherent-backscatter (CBOE) components and comparing photometry across observational scales. We use geostationary GaoFen-4 (...
