The Copernicus Sentinel-3A satellite saw the temperature at the top of Hurricane Harvey on 25 August at 0406 GMT as the storm approached the US state of Texas. The brightness temperature of the clouds at the top of the storm, some 12-15 km above the ocean, range from about -80°C near the eye of the storm to about 20°C at the edges.

Hurricanes are one of the forces of nature that can be tracked only by satellites, providing up-to-date imagery so that authorities know when to take precautionary measures.
