With Hurricane Matthew battering the southeastern United States, a fleet of Earth-watching weather satellites is tracking the storm from space, revealing staggering views like this temperature map of the hurricane's eye as seen from above.
The European Space Agency's Copernicus Sentinel-3A satellite captured this thermal view of Hurricane Matthew as it was approaching the eastern coast of Florida at 11:13 p.m. EDT on Thursday, Oct. 6 (0313 on Friday GMT). At the time, Matthew was monstrous, measuring 248 miles (400 kilometers) across and located 124 miles (200 km) from Miami Beach. ESA officials released the image Friday afternoon.

"Having already caused devastation in the Caribbean, Matthew is the most powerful hurricane to threaten the U.S. Atlantic coast in more than a decade – and it is thought that it could be the most catastrophic to hit Florida in more than a 100 years," ESA officials wrote in a description of the image.

The Sentinel-3A satellite data found that the temperature of the clouds at the top of Hurricane Matthew ranged from minus 112 degrees Fahrenheit (minus 80 degrees Celsius) at the top of the storm, just outside its eye — 7.4 miles (12 km) above sea level — to about 77 degrees F (25 degrees C) at the Atlantic Ocean's surface. The satellite used its sea and land temperature radiometer, an instrument that measures the energy radiating from the Earth in nine spectral bands, to make these observations.
As of 5 p.m. EDT (2100 GMT), Hurricane Matthew was a Category 2 storm with maximum wind speeds of 110 mph (175 km/h), according to an update from the National Hurricane Center. It was located about 40 miles (70 km) east of Jacksonville Beach, Florida, and 135 miles (215 km) south of Savannah, Georgia, and moving north at about 12 mph (19 km/h).
The Copernicus Sentinel-3A satellite launched into space on Feb. 16 and is part of a fleet of ESA satellites designed to study Earth in extreme detail. A sister satellite to Sentinel-3A, called Sentinel-3B, is scheduled to launch in 2017.
