NASA's TRMM Satellite views powerful Tropical Cyclone Ian

NASA's TRMM satellite passed over Tropical Cyclone Ian three days in a row and captured rainfall and thunderstorm cloud height data about the deadly storm as it strengthened and weakened. Powerful thunderstorms in Ian's eye wall were found reaching heights of about 15 km/9.3 miles. TRMM's data was used to create a 3-D flyby animation of Ian's well defined eye on January 11, 2014 at 0833 UTC [9:30pm Tonga local time].
