This site features one of the remarkable satellite pictures of Hurricane Isabel's North American landfall at 11:50 a.m. EDT on Sept. 18th, 2003. Red, green, and blue filtered images were combined to create a true-color view of the dangerous storm. There is a link to a similar image that was captured on Sept. 17th by a different satellite. Also mentioned are sister satellites TRMM, Jason-1, and QuickScat which are all members of NASA's Earth-observing fleet. Onboard instruments sense the temperature of the air, the distribution of moisture around the storm, the speed of its winds, and the heights of clouds.
