ASF SAR Data Products for Disaster Events
synthetic Aperture Radar (SAR) data is a powerful tool for monitoring and assessing disaster events and can provide valuable insights for researchers, scientists, and emergency response teams. The Alaska Satellite Facility (ASF) curates this collection of (primarily) SAR and SAR-derived satellite data products from a variety of data sources for disaster events.

Useful for
- Use cases llm-inferred
- Post-event flood extent mapping from SAR scenes for emergency response · Pre/post-event SAR comparison for rapid damage assessment after a disaster · Retrieving event-specific SAR scenes via STAC and COG for GIS analysis

Limitations
- Constraints llm-inferred
- Event-driven and irregular updates, so no fixed refresh schedule · Holdings depend on which disasters ASF has curated; not a continuous monitoring feed · Mainly SAR, so optical or other sensor data is not the primary content · Resolution and time span not stated in the docs; check per-product metadata
