Global Vegetation Index from MODIS
MODIS Land Science Team
MODIS will essentially monitor the "metabolism" of the Earth globally and regionally. This global snapshot shows where green foliage is being produced by land plants (green and dark green show greater productivity; yellow shows little or no production; red is a boundary zone), as the terrestrial biosphere "breathes in" carbon dioxide for photosynthesis.
