TM-004Surface composition, not the acquisition time gap, correlates with optical-to-SAR reconstruction error

SourceWhere and Why TerraMind's Optical-to-SAR Generation Fails

Surface composition dominates the correlation ranking: water, snow and ice are associated with higher residuals, while flooded vegetation is associated with lower residuals. The time gap between radar and optical acquisition is practically irrelevant.
