The global biosphere. False-colour composite satellite image of Earth's biosphere, showing the distribution of vegetation on land & phytoplankton in the oceans. The colours represent chlorophyll densities from red (most dense) through yellow & blue to pink (least dense) in the oceans; and from dark green to pale yellow on land. The ocean data was acquired by the Coastal Zone Colour Scanner (CZCS), a radiometer with visible light & infrared channels on NASA's Nimbus-7 satellite. The land data is derived from the visible & infrared sensors of the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA-7 satellite.
