Addressing InSAR long wavelength errors enhances the reliability of GNSS and InSAR combined 3D deformation estimation: methodology and application to the 2011 Tohoku-Oki earthquake
Interferometric Synthetic Aperture Radar (InSAR) deformation measurements are susceptible to long wavelength errors, yet existing geometric and strain models for estimating three-dimensional (3D) deformation from combined Global Navigation Satellite System (GNSS) and InSAR observations do not explicitly account for t...
