Introduction
The neutral atmosphere affects the InSAR observations in the same way as the GNSS. Reanalyses are also considered as a promising external data source to correct InSAR atmospheric delays and have been frequently used in many previous studies, especially the ERA-Interim (e.g., Joviet et al. 2011). The latest ERA5, with higher temporal and spatial resolution compared to ERA-Interim, can be expected for a better performance in providing InSAR atmospheric delay estimates. Users can also get the InSAR atmospheric delay correction information for their interested region.
