Validation of CAMS-EAC4 and MERRA-2 aerosol reanalysis products for multisatellite atmospheric correction: a case study over Japan with applications to East Asia
Accurate atmospheric correction is critical for multi-satellite Earth observation systems, particularly in dryland ecosystems where aerosol variability significantly affects surface reflectance retrievals. Global reanalysis datasets such as CAMS-EAC4 and MERRA-2 provide spatially continuous aerosol parameters, but thei...
