Satellite Image of the Day: August 23, 2004
(click here for previous images of the day)

Satellite: NOAA-17, one of NOAA's 850km-high (530 mile-high) Polar Orbiting satellites.
Flyover beginning 7:37am EDT
Virginia on a clear, sunny morning.
The circle shows the location of Radford University, in the heart of the New River Valley, the site of this image download.
The morning fog in the mountain valleys nicely delineates the surrounding peaks. The backbone of the Blue Ridge Mountains is seen clearly at the eastern boundary of the mountains here.
The angle of the shadows from the clouds tells you that this image was taken in the early morning with the sun low on the (east-northeast) horizon.
Note how you can see the straight vapors trails left by airplanes (jet engines) in the eastern part of the state. These jet contrails are water vapor trails that can be tracked by satellite and they can last for a significant amount of time depending on atmospheric moisture content, wind speed and turbulence, etc.
