ARIA Damage Proxy Map (Copernicus Sentinel-1) for Hurricane Ian
Date of Image: 10/2/2022 Date of Next Image: Unknown Summary: The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and California Institute of Technology created the multi-temporal coherence-based Damage Proxy Map (DPM2) depicting areas that are likely damaged in Florida state in the U.S. due to Hurricane Ian in September 2022. This map was derived from synthetic aperture radar (SAR) images acquired by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA) from 05 April 2022 to 02 October 2022. Suggested Use: The color variation from pale yellow to red indicates increasingly more significant surface change (drop in radar reflection coherence). Preliminary validation was done by comparing with the Media reports and other images. This damage proxy map should be used as guidance to identify damaged areas or areas affected by flood and may be less reliable over vegetated areas. The changes in radar reflections from flooded land and damaged buildings cannot be separated easily. For example, the scattered colored pixels over vegetated areas may be false positives, and the lack of colored pixels over vegetated areas does not necessarily mean no damage. Satellite/Sensor: Copernicus Sentinel-1 Synthetic Aperture Radar (SAR) Resolution: 30 meters Credits: Sentinel-1 data were accessed through the Copernicus Open Hub and the Alaska Satellite Facility server. The product contains modified Copernicus Sentinel data (2022), processed by ESA and analyzed by the NASA-JPL/Caltech ARIA team. NASA's Earth Applied Sciences Disasters Program provided part of the funding.
