Hurricane Helene was a devastating tropical cyclone that produced a wide swath of damage and loss of life that extended from northwest Florida, US, where the storm made landfall on 26 September 2024, to Tennessee, Georgia and North Carolina.<\/p>\n
Hurricane Helene was closely monitored using Copernicus Sentinel-1 radar data to assess its wind field over the ocean surface. This technology plays a crucial role in understanding storm dynamics and predicting their impacts.<\/p>\n
Satellite-based sensors, particularly those operating in microwave frequencies, can capture data on ocean surface wind speed and direction under various weather conditions. The Ocean Wind Field (OWI), derived from Sentinel-1, provided detailed estimates of wind vectors at 10 m above the ocean surface. This information is essential for meteorologists to analyse the storm’s intensity and trajectory.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n
