Planet Earth gets a makeover
![]() Blue Marble 2000 (Stockli, Nelson and Hasler)
Nasa scientists have created this stunning new image of the Earth. It is a composite using data from three different Earth-observing satellite instruments.
Part of the new portrait shows an immense hurricane in the Eastern Pacific - Hurricane Linda. You can also see the shallow, azure waters of the Caribbean and sediments around the mouth of the Amazon River. Exaggerated heights On land, heavy vegetation is green and sparse vegetation is yellow. The heights of mountains and depths of valleys have been exaggerated by 50 times their actual levels so that vertical relief is visible. The shadows for the mountains were calculated from the exaggerated heights.
The Nasa scientists were based at the Laboratory for Atmospheres at the Goddard Space Flight Center. They used data from the Geostationary Operational Environmental Satellite (Goes), the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) satellite and the Polar Orbiting Environmental Satellites (Poes).
