New satellite will bounce light off air to measure winds

BERLIN—Whichever way the wind blows, a new satellite launched yesterday will be watching it.

The Aeolus satellite will be the first to directly measure wind speeds and directions all over the globe, allowing scientists to improve worldwide weather forecasts.

“This has not been done before from space,” said project scientist Anne Grete Straume of the European Space Agency.
