Global Enhanced Vegetation Index Measurements
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science.
The Moderate-resolution Imaging Spectroradiometer (MODIS) Enhanced Vegetation Index (EVI)
provides a look at vegetation around the globe year round. These seasonal images were made from averaging two months of MODIS EVI observations centered on the first day of each season: a month before and after June 21, 2000, and December 21, 2000. As the seasons change, the mirror
effect of seasonality is seen, with vegetation alternatively blooming and fading in each hemisphere. For instance, the Northern Hemispheres vegetation is high while the Southern Hemispheres is low. The index values in this false-color image range from 0, indicating no vegetation, to nearly 1,
indicating densest vegetation. Gray areas indicate places where
observations were not collected.
