English: Tropical Storm Isidore was born in mid-September north of Venezuela. It subsequently hit Mexico's Yucatan Peninsula as a Category 3 hurricane and came ashore near New Orleans on September 26th packing winds just below hurricane strength. Around the time of September 27, 2002, the storm was downgraded to a tropical depression as the system moved into Tennessee.
At the time the Aqua spacecraft first passed over Isidore, it was classified as a Category 3 (possibly 4) hurricane, with minimum pressure of 934 mbar, maximum sustained wind speeds of 110 knots gusting to 135 knots, and an eye diameter of 20 nautical miles. Isidore was later downgraded to a Tropical Storm and then a Tropical Depression as it lost energy. This image was made with data from the microwave component (AMSU-A) of the Atmospheric Infrared Sounder on NASA's Aqua satellite. The Aqua satellite has an exact 16-day repeat cycle which gives exactly the same coverage of Earth, making it possible to obtain a difference image. This image is the difference between data collected on September 12, 2002 and September 28, 2002. In the difference image, white indicates no difference at all, green is very little difference, blue/purple indicates primarily heavy flooding. Red indicates warming likely due to warmer weather. The straight lines on the right and left edges of the difference image are caused by slight differences between the two repeat passes of Aqua.

Working in tandem, the two instruments 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-dimensional map of atmospheric temperature and humidity, cloud amounts and heights, greenhouse gas concentrations, and many other atmospheric phenomena. The AIRS and AMSU fly onboard NASA's Aqua spacecraft and are managed by the Jet Propulsion Laboratory, Pasadena, California, under contract to NASA. JPL is a division of the California Institute of Technology in Pasadena.
