description: The ARIA Sentinel-1 Geocoded Unwrapped Interferogram (S1-GUNW) product provides standardized, geocoded, unwrapped interferograms derived from Sentinel-1 Interferometric Wide-swath (IW) SAR data. Each product represents the interferometric phase difference between a reference (newer) and a secondary (older) SAR acquisition, enabling detection of centimetre-scale surface deformation caused by earthquakes, volcanic activity, landslides, and subsidence. Products are provided as CF-compliant NetCDF4 files at 90-metre pixel spacing in geographic coordinates (EPSG:4326). Processing is performed via the open-source ISCE2 TopsApp pipeline on AWS HyP3, operated by the Advanced Rapid Imaging and Analysis (ARIA) project at NASA/JPL and ASF DAAC. The dataset contains modified Copernicus Sentinel data processed by ESA and ARIA NASA/JPL.
