Service Description: Date of Imagery: 10/26/2018 Purpose/Summary: Sentinel-1 Synthetic Aperture Radar (SAR) captured the moment of landfall of the eye of Hurricane Willa on October 26, 2018 UTC. These images are composed of single band "before" (VH polarization) Sentinel 1 SAR data and "during" or immediately "after" SAR data. Suggested Usage: Land areas that changed to smoother radar reflectivity will be in various shades of red; those that are rougher will appear as blue. Data are provided at their full (~ 10 m) spatial resolution in latitude and longitude projection. These images have no interpretation attached, but are provided immediately here after creation: for end users with processing systems and expertise sufficient to perform their own interpretation of changed areas. Satellite/Sensor: ESA Sentinel-1 Synthetic Aperture Radar (SAR) Resolution: ~10m Credits/Acknowledgements: Source data are from Copernicus/ESA Sentinel Synthetic Aperture Radar (SAR); image processing was performed at the Dartmouth Flood Observatory, University of Colorado, with funding support from the NASA Applied Sciences Program.
