The instrument is so sensitive that it could be damaged by a sudden loss of pressure. For this reason, air transportation has to be avoided and for the first time Airbus will transport one of its satellites on-board its own vessel.
The 1.33-tonne spacecraft, primed by Airbus, features the first ever space-borne LIDAR (LIght Detection And Ranging) instrument called Aladin, which uses the Doppler effect to determine the wind speed at varying altitudes.
Aladin fires a powerful ultraviolet laser pulse down through the atmosphere and collects backscattered light, using a large 1.5m diameter telescope, which is then analysed on-board by highly sensitive receivers to determine the Doppler shift of the signal from layers at different heights in the atmosphere.
"Aeolus is a world first with break-through technology that will make a huge contribution to weather forecasting on a global scale. Pioneering a LIDAR instrument in Space is quite a challenge - but a great example of what Europeans can achieve when we work together!", said Nicolas Chamussy, Head of Space Systems at Airbus.
The data from Aeolus will provide reliable wind-profile data on a global scale and is needed by meteorologists to further improve the accuracy of weather forecasts and by climatologists to better understand the global dynamics of Earth's atmosphere.
Aeolus will orbit the Earth 15 times a day with data delivery to users within 120 minutes of the oldest measurement in each orbit. The orbit repeat cycle is 7 days (every 111 orbits) and the spacecraft will fly in a 320 km orbit for three years.
