Before ESA’s Aeolus satellite is packed up and shipped to French Guiana for liftoff in August, media representatives had the prospect to see this wind measuring Earth Explorer satellite standing proud within the cleanroom.


Like the entire Earth Explorers, Aeolus was constructed to point out how cutting-edge can shed new mild on the intricate workings of our planet.

This pioneering satellite makes use of highly effective laser expertise that probes the lowermost 30 km of our ambiance to yield vertical profiles of the in addition to data on aerosols and clouds.

This is not going to solely enhance our understanding of how the ambiance works and contribute to local weather change analysis, however can even assist to foretell excessive occasions reminiscent of hurricanes and El Niño.

While Aeolus is ready to advance science, it’s going to additionally carry appreciable advantages to society by bettering .

It goes with out saying that correct climate forecasts are essential for companies reminiscent of farming, fishing, building, transport, power exploitation and in addition for simply planning our each day affairs.

Although climate forecasts have superior significantly in recent times, meteorologists urgently want dependable international wind-profile knowledge to enhance the forecasts even additional.

The Aeolus mission is not going to solely advance our understanding of atmospheric dynamics, however can even present much-needed data to enhance climate forecasts. The satellite carries the primary wind lidar in area, which might probe the lowermost 30 km of the ambiance to supply profiles of wind, aerosols and clouds alongside the satellite’s orbital path.The laser system emits brief highly effective pulses of ultraviolet mild down into the ambiance. The telescope collects the sunshine that’s backscattered from air molecules, particles of mud and droplets of water. The receiver analyses the Doppler shift of the backscattered sign to find out the pace and path of the wind at numerous altitudes under the satellite. These near-realtime observations will enhance the accuracy of numerical climate and local weather prediction and advance our understanding of atmospheric dynamics and processes related to local weather variability.

Currently data on the wind comes from climate balloons, ground-based devices, plane, from monitoring cloud motion and from satellite devices that measure wind close to the ocean floor.

Aeolus measures the wind across the globe and delivers its measurements virtually in actual time, which is strictly what meteorological centres want to enhance our forecasts.

Carrying a few of the most refined area expertise ever developed, it has taken some years to get this far, however now Aeolus is able to be shipped to the launch web site in Kourou, French Guiana for liftoff on 21 August.

ESA’s Director of Earth Observation Programmes, Josef Aschbacher, mentioned, “We are very proud to see Aeolus right here right now at Airbus Defence and Space in Toulouse, France.

“It has been a rocky highway creating this unbelievable mission, however no one ever mentioned was simple. Aeolus is a real first and we all know that it’s set to make an actual distinction to our understanding of the planet in addition to have actual world purposes.

“I am very grateful to everyone that has worked so hard to reach this point and we look forward to the next step, shipping and preparing for liftoff.”
