Image of the Blue Marble 2000

The underlying image of the full disk of Earth and its clouds was taken on September 9, 1997, by a Geostationary Operational Environmental Satellite (GOES) operated by the U.S. National Oceanic and Atmospheric Administration (NOAA), and built by NASA. The ocean color data was collected in late September and early October 1997 by NASA's Sea-viewing Wide Field-of-view Sensor (SeaWiFS) satellite. The land color is portrayed by a vegetation index calculated using data collected from September 9-19, 1997, by Advanced Very High Resolution Radiometer (AVHRR) instruments carried aboard NOAA's Polar Orbiting Environmental Satellites (POES).
