InSAR Performance for Large-Scale Deformation Measurement: Impact of Tropospheric Corrections and Validations

This paper deals with the analysis of InSAR performance for large-scale deformation measurement. The study evaluatesthe use of models, especially numerical weather prediction re-analysis, to mitigate disturbances in SAR interferograms. The impact of such corrections is evaluated and, using GNSS measurements, the predicted error bars are validated on a large Sentinel-1 dataset
