Poyang Lake drawdown-zone: Intensity of InSAR and vertical deformation (2017-2026)

This dataset contains GeoTIFF products for the Poyang Lake drawdown zone, China, derived from 265 Sentinel-1 SAR acquisitions between 26 March 2017 and 27 March 2026. It comprises 265 radar multilook intensity images (RMLI), 265 corrected cumulative vertical displacement maps, and six vertical deformation rate maps: a basin-wide datum-harmonized field, a full-period skeleton-network field, and fields for four hydrological exposure groups (G1–G4).
