The changing of the leaves can be seen in space by the SeaWiFS instrument. Shown here are 3 datasets that show the change.

A flyby of the Washington-Baltimore corridor, from Landsat imagery draped over elevation data

Using data from different spacecraft and some powerful computer technology, visualizers at the Goddard Space Flight Center present you with a collection of American cities in a way you have never seen them before. Starting with our camera high above the Earth, we rush in towards the surface at what would be an impossible speed for any known vehicle. Passing though layers of atmosphere, the colors of our destinations shimmer with their own unique characteristics, and suddenly we find ourselves floating in virtual space just above the ground.

This animation follows Hurricane Isabel (2003) from its birthplace in the Ethiopian Highlands of East Africa, across the Atlantic Ocean, to the United States. Atlantic hurricanes are often formed as winds over the Gulf of Aden intersect with the Ethiopian Highlands. This animation zooms into the Ethiopian Highlands and shows several storms being formed. Then, the animation dissolves in a reticle to focus in specifically on the formation of Hurricane Isabel. The reticle follows the storm across Africa and into the Atlantic. The path and intensity of Hurricane Isabel is depicted by a colored path. Blue represents the genesis of the storm. Green is a Tropical Depression where winds are less than 39 miles per hour. Yellow is a Tropical Storm where winds are between 39 and 73 miles per hour. Red is a category 1 hurricane where winds are between 74 and 95 miles per hour. Light Red is a category 2 hurricane with winds between 96 and 110 miles per hour. Magenta is a category 3 hurricane with winds between 111 and 130 miles per hour. Light magenta is a category 4 hurricane with winds between 131 and 154 miles per hour. White represents a category 5 hurricane where winds are greater than 155 miles per hour. Note how Isabel gains size and speed over the warm waters of the Atlantic.

This is a side-by-side image of Marylands Liberty Reservoir. The image on the left is a Landsat image from July 1997. The image on the right is also a Landsat image, but it was taken in July of 1999 after two consecutive years of drought.

Zoom down to Liberty Reservoir comparing July, 1997 and July, 1999. This animation shows Landsats view of Marylands Liberty Reservoir from its normal levels in July of 1997 to its extreme low levels during the drought of 1999.
