Summary:
The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and California Institute of Technology in Southern California created this Damage Proxy Map (DPM) depicting areas that are likely damaged by the Tornadoes (December 10, 2021) in Kentucky state, US. The map was derived from synthetic aperture radar (SAR) images on Dec 11, 2021 by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA). The pre-event images were taken from June 26, 2021 to Nov 17, 2021. Preliminary validation was done by comparing with the Media reports and drone images.
Suggested Use:
The color variation from yellow to red indicates increasingly more significant surface change.
This damage proxy map should be used as guidance to identify damaged areas, and may be less reliable over vegetated. 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. This map is most sensitive to building damage, but small-scale change or partial structural damage may not be detected by this map.
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 (2021), processed by ESA and analyzed by the NASA-JPL/Caltech ARIA team. Part of the funding was provided by NASA's Earth Applied Sciences Disasters Program.
