Satellites View Earth in a Different Light
Alt Tag: Earth’s temperature as seen from space.Movie Description:
Other kinds of satellite sensors look at the Earth in a far different light. Heat sensing satellite instruments take the Earth's temperature by measuring infrared energy. Infrared wavelengths are invisible to our eyes, but some satellites can see them. And, as our climate changes, we can see ocean temperatures on the rise.
Other satellites show us peaks and valleys, not just on land - but, believe it or not - on the surface of the ocean. And as ice on land melts, there are increasingly more highs than lows. Sea level is rising. View full movie here
