Scientists Use Meteors To Investigate Climate Change And Giant Waves At 'Edge Of Space' (http://www.sciencedaily.com/releases/2005/07/050706003830.htm)


A new research radar based in Antarctica is giving scientists the chance to study the highest layer of the earth’s atmosphere at the very edge of space.

Using the new radar, scientists will be able to investigate climate change and explore the theory that while the lower atmosphere is warming, the upper atmosphere is cooling by as much as 1 degree centigrade each year.

“Meteors, or ‘shooting stars’, burn up in the mesosphere. The meteors drift just like weather balloons so we can use a radar on the Earth and bounce radio waves off the meteors to find how fast they are moving and so measure the winds at the edge of space.
