In the video, our planet's ice caps and snow cover can be seen ebbing and flowing as seasons go by.
"As the satellite archive expands, you see more and more dynamics growing", said Jeffrey Masek, chief of the Biospheric Sciences Laboratory at NASA. The changes in temperature have resulted in more green matter in the Arctic; the shrubs have extended beyond their typical range as areas become warmer than they were in past years. Exploring exoplanets with a telescope "Spitzer", the scientist discovered changes its brightness, which may indicate it has atmosphere, like earth's.
Clouds of algae phytoplankton flourish and perish in distinct cycles on the world's oceans, denoting surface temperature fluctuation and pointing to atmospheric events, including El Niño and La Niña, that profoundly affect human life.
Several satellites were used between September 1997 and September of this year, to compile the data. "It's really remarkable", said NASA oceanographer Jeremy Werdell, who took part in the project.
According to Werdell, the visualisation shows spring coming earlier and autumn lasting longer in the Northern Hemisphere. Also noticeable to him is the Arctic receding over time - and, though less obvious, the Antarctic, too. This algae bloom is evident by a line of bright green.
Nasa first began keeping a continuous view of life on Earth in September 1997 using several satellites called the Sea-Viewing Wide Field-of-view Sensor (SeaWiFS).
Werdell said that the data could prove extremely useful for lawmakers as well as commercial fishermen and other professions.
Just like our Earth, the visualization will continually change, officials said, as computer systems improve, new remote-sensing satellites are launched and more observations are made.
