Removing Tides and Inverse Barometer Effect on DInSAR of Antarctic Ice Shelves
Surface displacements are of particular interest for characterizing the dynamics of Antarctic ice shelves. Differential Synthetic Aperture Radar Interferometry (DInSAR) is a common technique from which high-resolution velocity maps can be inferred at high accuracy. However, though vertical displacem...
