Monitoring of Vertical Land Motion at Tide Gauges Using Time-Series Sequential SBAS Technique

Relative sea level changes from tide gauges requires various corrections including local vertical land motion due to natural and anthropogenic processes. This study aims to measure the vertical land motion at tide gauges in the Korean peninsula using StaMPS-SBAS time-series InSAR analysis. C-band Sentinel-1 A/B SAR data acquired during 2014/10 and 2020/05 for this study. We applied sequential pairs selection approach to optimize the amplitude dispersion index (ADI) and increase the PS pixel density.
