ARIA-S1-GUNW: Sentinel-1 Interferograms for Geohazard Monitoring

JPL ARIA project Level-2 interferometric products derived from Sentinel-1 SLC data using ISCE v2.0.0. These geospatial datasets support InSAR science for monitoring tectonic activity, volcanic regions, and areas of subsidence or uplift. The product generation was funded in part by the AWS Open Data Program and NASA ROSES.

Use Cases

• Monitoring tectonic plate motion based on interferometric phase measurements.
• Assessing volcanic inflation or deflation preceding eruptions.
• Measuring land subsidence or uplift in urban or agricultural areas.
• Analyzing coastal change processes like shoreline erosion or delta formation.

Strengths

• Produced by the authoritative Jet Propulsion Laboratory (JPL) ARIA project.
• Supports science across multiple high-impact domains: tectonics, volcanology, and coastal processes.
• Cross-platform presence on NASA Earthdata and Data.gov signals established importance and accessibility.

Limitations

• Column names and detailed schema are not provided in any source, limiting precise understanding of data structure.
• Conflicting 'last updated' dates exist (2026-04 09 and 2023-05-28), creating uncertainty about dataset freshness.
• License is ambiguously listed as 'other-license-specified' without explicit terms.
