Abstract

Atmospheric water vapor effects represent one of the major limitations of repeat- pass InSAR, and limit the accuracy of deformation rates derived from InSAR. The use of contemporaneous MERIS data to correct ENVISAT ASAR measurements shows a significant reduction in water vapor effects. After correction, the RMS differences between GPS and InSAR range changes in the satellite line of sight direction decreased to 0.55 cm with a reduction of up to 0.35 cm. It is also shown that it is possible to implement an extra ' conservative' cloud mask and obtain better water vapor corrections than that from using the official ESA cloud mask product.
