Studying a Storm From Many Angles
infrared view of Hurricane Ivan Cloud Temperature
JPL's Atmospheric Infrared Sounder Experiment captured this infrared view of Hurricane Ivan in September 2004. The instrument, which flies aboard NASA's Aqua satellite, measures the temperature of cloud tops. The lowest temperatures (seen in purple) are associated with high, cold cloud tops that make up the top of the hurricane. Warmer areas are closer to red.
