Hurricane Celia
| Title |
Hurricane Celia |
| Description |
The image above shows Tropical Storm Celia on July 21, 2004, in visible light, as you would perceive it from space. Located in the eastern north Pacific Ocean off the coast of Mexico, Celia has a small eye with an 80-90 percent closed eyewall. Celia briefly reached hurricane status on July 22 when sustained winds reached 75 miles per hour and gusts reached 92 mph, making it the first hurricane of the eastern north Pacific season. This image was acquired by the Atmospheric Infrared Sounder (AIRS). The Atmospheric Infrared Sounder Experiment, with its visible, infrared, and microwave detectors, provides a three-dimensional look at Earth?s weather. Working in tandem, the three instruments can make simultaneous observations all the way down to the Earth?s surface, even in the presence of heavy clouds. With more than 2,000 channels sensing different regions of the atmosphere, the system creates a global, 3-D map of atmospheric temperature and humidity and provides information on clouds, greenhouse gases, and many other atmospheric phenomena. The AIRS Infrared Sounder Experiment flies onboard NASA?s Aqua [ http://aqua.nasa.gov/ ] spacecraft.

Tropical Storm Bonnie as Observed by NASA's Spaceborne Atmospheric Infrared Sounder (AIRS) |
| Original Caption Released with Image |
This image of tropical storm Bonnie was captured on August 11 at 1:30am CDT. Located in the Gulf of Mexico, the center of the storm is positioned about 280 miles south-southwest of the mouth of the Mississippi River. Bonnie is a small tropical storm with wind speeds sustained at 45 mph and extending 30 miles from the storm center. It is moving northward at 5 mph. About the Movies The major contribution to radiation (infrared light) that AIRS infrared channels sense comes from different levels in the atmosphere, depending upon the channel wavelength. To create the movies, a set of AIRS infrared channels were selected which probe the atmosphere at progressively deeper levels. If there were no clouds, the color in each frame would be nearly uniform until the Earth's surface is encountered. The tropospheric air temperature warms at a rate of 6 K (about 11 F) for each kilometer of descent toward the surface. Thus the colors would gradually change from cold to warm as the movie progresses. Clouds block the infrared radiation. Thus wherever there are clouds we can penetrate no deeper in infrared. The color remains fixed as the movie progresses, for that area of the image is "stuck" to the cloud top temperature. The coldest temperatures around 220 K (about -65 F) come from altitudes of about 10 miles. We therefore see in a 'surface channel' at the end of the movie, signals from clouds as cold as 220 K and from Earth's surface at 310 K (about 100 F). The very coldest clouds are seen in deep convection thunderstorms over land. Images August 11, 2004 Infrared image. August 10, 2004 Daylight snapshot from AIRS visible/near-infrared sensor.

The tropospheric air temperature warms at a rate of 6 K (about 11 F) for each kilometer of descent toward the surface. Thus the colors would gradually change from cold to warm as the movie progresses. Clouds block the infrared radiation. Thus wherever there are clouds we can penetrate no deeper in infrared. The color remains fixed as the movie progresses, for that area of the image is "stuck" to the cloud top temperature. The coldest temperatures around 220 K (about -65 F) come from altitudes of about 10 miles.
