Blue
Marble is a spectacular true-color image of the entire Earth.
Put together from data of 18 of the most advanced Earth-observing
satellites ever built, such as Terra and Aqua, the Blue
Marble can be seen in all its glory at a spatial resolution of
500 meters (500 meter/pixel) in 12 versions, one for each month of
year. The above image is the monthly composite for the month of July
2004. Cloud-contaminated or otherwise bad data are automatically
recognized by the Blue Marble computer technique and removed.
The July 2004 monthly composite with
"global
clouds" is just a click away.
