In this study, we evaluate the performance of ERA-Interim global atmospheric reanalysis on estimating the tropospheric delay on Sentinel-1 InSAR observations. The results are validated by four D-InSAR interferograms with small temporal/perpendicular baselines computed from Sentinel-1 observations. Based on the study, we concluded that the ERA-Interim global atmospheric reanalysis has relatively better performance in the regions with significant topography and stable atmospheric conditions.
