NASA's OPERA Project Generates Radar Image of Hurricane Helene

This scientific visualization presents a radar image of Hurricane Helene as it approached Florida's Gulf Coast on September 26, 2024. Produced by NASA's OPERA project using Synthetic Aperture Radar (SAR) observations from the Copernicus Sentinel-1A satellite, the image reveals the storm's structure through false-color radar data rather than visible light.

The vivid magenta and purple tones represent rough ocean surfaces generated by powerful winds, while green indicates vegetation, pale pink and white identify urban areas, and dark regions correspond to calm water. The storm's eye appears as a dark circular feature over the Gulf of Mexico, demonstrating the unique ability of radar satellites to observe Earth's surface through clouds and at any time of day.
