The Aeolus mission will improve weather forecasts
Today’s Video of the Day from the European Space Agency is a special edition of the Earth from Space series that describes the mission of Aeolus, a newly-developed wind satellite that will be launched from French Guiana next month.
The Aeolus mission will be the first to collect wind data on a global scale. This data will be used to improve the accuracy of weather forecasts and create better climate models.
Aeolus produces a powerful laser beam that bounces off air particles in the atmosphere. The changing frequencies of the light that is reflected back to the spacecraft are used to calculate wind speeds at different altitudes.
