A new documentary premiering tonight (Feb. 13) on PBS promises to show the Earth as you've never seen it before ... from space.
Produced by NOVA, the documentary "Earth from Space" explores how satellites and spacecraft have revolutionized how scientists look at the world and its intricate systems.
Only by taking a satellite eye's view of the Earth can scientists studying the geology and climate of the planet gain a sense of just how interconnected the sea, land and air of the planet are, saidWaleed Abdalati, the director of the Earth Science and Observation Center run through the University of Colorado at Boulder and a participant in the two-hour documentary.
"I think intuitively we know there are connections, but when you can actually trace dust storms off the Sahara to weather events in North America it changes things," Abdalati said.
Thanks to satellite data, climate models have been refined, Abdalati added. All 15 climate models in place before most of the Earth-observing satellites were launched have now been changed to reflect the new data gathered by the satellites. Scientists have taken that information to craft a more accurate picture of what future climates could look like
