Excerpt
Using airborne spectrometers like those that have mapped the face of Jupiter, researchers charted potentially toxic dust from the disintegrated towers. Others pored over weather-satellite data to see how the lack of contrails in the planeless skies affected weather patterns.
Some are available at a Web site for the National Aeronautics and Space Administration,www.gsfc .nasa.gov.
At NASA's Langley Research Center, in Hampton, Va., Louis Nguyen, a computer engineer, compiled images from the weather-trackingGOES-8 satellite, pulling data recorded over New York City every quarter hour in grainy half-mile-wide pixels.
From Sept. 16 to Sept. 23, a Twin Otter airplane crossed lower Manhattan with an airborne visible-infrared imaging spectrometer,Aviris, that divines the composition of materials a mile or more below by the way they reflect or absorb sunlight.
