Similar to GNSS observations, InSAR observations are also influenced by the neutral atmosphere. Reanalysis data, especially ERA-Interim data, is considered the most promising external source for correcting atmospheric delay in InSAR and is often used in related research (e.g., Joviet et al. 2011). The latest ERA5 data offers higher spatial and temporal resolution compared to ERA-Interim and is expected to improve estimates of InSAR atmospheric delay. Users can access corrected InSAR atmospheric delay information for the area of interest (based on ERA5 reanalysis data) through this platform
