NASA On Air: NASA Satellites Show Global Biosphere Yearly Cycle (4/22/2015)

Released on April 22, 2015

LEAD: A new view from NASA satellites show how the earth “greens up" during spring and summer in the Northern Hemisphere. Here is an entire year in seven seconds.

1. The green color represents plant growth on land, which is caused by increased sunlight during longer days (daylight).

2. In the ocean, plant life is represented by the teal color. This color represents populations of tiny marine plants called phytoplankton.

TAG: The satellite data has been averaged over ten-year periods and provides long-term views of how Earth changes.
