An Inside Satellite Look at Tropical Storm Debby's Clouds

Caption

This is an infrared image of Tropical Depression Debby in the Atlantic, from the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite on Aug. 22, 2006. This AIRS image shows the temperature of the cloud tops or the surface of the Earth in cloud -- free regions. The lowest temperatures (in purple) are associated with high, cold cloud tops that make up the top of the storm. The infrared signal does not penetrate through clouds. Where there are no clouds the AIRS instrument reads the infrared signal from the surface of the Earth, revealing warmer temperatures (red). At the time the data were taken from which these images were made the eye had not yet opened but the storm is now well organized. The location of the future eye appears as a circle in the microwave image just to the southeast of the Azores (Islands).
