TIME SERIES OF SALT CRUSTS IMAGED BY A DUAL POLARIZATION SPACEBORNE SYNTHETIC APERTURE RADAR (SAR) AT C-BAND OVER AN ANDEAN ALTIPLANO SALAR OF NORTHERN CHILE [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 Abstract. A dense time series of Synthetic Aperture Radar acquisitions at 6-day intervals between July 2017 to January 2019 collected with the C-band constellation Sentinel 1A and 1B is used to study salt crust evolution in an highland salar. Microwave response of halite crystal aggregates is linked to surface roughness of the salt crusts by means of a
