Sentinel-1 P-SBAS multilook interferogram sequences and triangulation networks
The files here support the analysis presented in the Comment on “Study of Systematic Bias in Measuring Surface Deformation With SAR Interferometry” by Ansari et al. (2021), published in IEEE Transactions on Geoscience and Remote Sensing . In particular, we provide in the following the instructions to access the multilook interferogram sequences exploited in our Comment and their ancillary information.
This dataset contains modified Copernicus Sentinel data .

The overall dataset is composed of three multilook interferometric sequences retrieved by processing, through the P-SBAS processing chain described in , the 230 Sentinel-1 images acquired from ascending orbits (track 44) over Sicily (Southern Italy) between May 2016 and May 2020.
The interferometric datasets, referred hereafter to as “short-time”, “medium-time” and “long-time”, respectively, are encapsulated within a different zip file. Instructions to manage the datasets are provided in the pdf attached file.
