Cover: A digitally enhanced image created from data acquired by a Geostationary Operational Environmental Satellite (GOES) operated by NOAA and built by NASA; by NASA’s Sea-viewing Wide Field-of-view Sensor (SeaWiFS) satellite; and by Advanced Very High Resolution Radiometer (AVHRR) instruments carried aboard NOAA’s Polar Orbiting Environmental Satellites (POES). These data were draped across a digital elevation model of Earth’s topography from the U.S. Geological Survey. Heavy vegetation is shown as green and sparse vegetation as yellow. The heights of mountains and depths of valleys have been exaggerated so that vertical relief is visible. The presence of the Moon in this image is an artistic addition; the lunar image was collected by GOES in September 1994 and has been magnified to about twice its relative size. The prominent storm raging off the west coast of North America is Hurricane Linda (1997). This image was created by Reto Stockli with the help of Alan Nelson, under the leadership of Fritz Hasler. A detailed description of how the image was generated is available at http://rsd.gsfc.nasa.gov/rsd/bluemarble/bluemarble2000.html.
