Fall Colors from Space
October 26, 2003
The above satellite image pair (true color) was taken within four days of each other. The image at top was taken on October 10, and the bottom image acquired on October 6. In just a few short days, the trees surrounding Lake Superior and Lake Michigan, in northern Wisconsin and the Upper Peninsula of Michigan, have traded in their summer attire for a new autumn wardrobe. The Moderate Resolution Imaging Spectroradiometer(MODIS) sensor on NASA’s Terra satellite captured the top image, and a similar sensor on the Aqua satellite retrieved the bottom image. The resolution (pixel size) is approximately 250 m. Images courtesy Liam Gumley, Space Science and Engineering Center, University of Wisconsin-Madison.
