    • Abstract
  • A comparison between GPS topography-dependent turbulence model(GTTM) and GPS/MODIS integrated water vapour correction model is performed.The experimental results show that both correction models are able to improve InSAR derived deformation signals from 10 mm to 5 mm after correction by reducing water vapour effects on InSAR measurements.It can also be concluded that the GTTM and GPS/MODIS integrated models are complementary when correcting InSAR measurements.
