On the accuracy of integrated water vapor observations and the potential for mitigating electromagnetic path delay error in InSAR.

The article presents a study on the accuracy of atmospheric columnar integrated water vapor measurements based on the Mitigation of Electromagnetic Transmission errors induced by Atmospheric Water Vapour Effects (METAWAVE) project. The study investigates the mitigation of integrated water vapor (IWV) effects into the Spaceborne Interferometric Synthetic Aperture Radar (InSAR). It concludes that InSAR sensitivity to water vapor turbulent component is higher compared to other instruments.
