A Global View of Seasonal NDVI
Satellite data can be used to monitor the health of plant life from space. The Normalized Difference Vegetation Index (NDVI) provides a simple numerical indicator of the health of vegetation which can be used to monitoring changes in vegetation over time. This animation shows the seasonal changes in vegetation by fading between average monthly NDVI data from 2004. The loop begins on September 24 and repeats six times during one full rotation of the globe at a rate of one frame per day. The fade for each month is complete on the 15th of each month.

This animation shows seasonal change in vegetation around the globe as measured by the NDVI value.    This animation shows seasonal change in vegetation around the globe as measured by the NDVI value.
