Later near two decades of design and testing, the European Space Agency (ESA) has successfully launched the Aeolus satellite. Aboard the satellite is a laser that volition measure wind speeds across the globe. Aeolus could vastly increase the information scientists have on wind speeds, improving weather forecasting and providing new resources to climate researchers.

The ESA began the Aeolus project way back in 2002, but the laser instrument was more than challenging to design than anyone expected. Information technology was supposed to launch in 2007 originally. Airbus Defense force and Space handled the principal construction at a final cost of €480 meg ($550 one thousand thousand), but it could be well worth the price equally Aeolus delivers extensive atmospheric data never before available to scientists. This is the 5th launch in the ESA's Globe Explorer program, which uses satellites to accept improved measurements of specific parts of Earth.

Aeolus headed into space early on Baronial 23 aboard a Vega rocket launched from the ESA's facility in French Guiana. The Aeolus satellite detached from the rocket 55 minutes into the flight and ground stations reported confirmed contact with the spacecraft. At present, Aeolus will turn its light amplification by stimulated emission of radiation toward World to gather data.

Later settling into a polar orbit 199 miles higher up the planet, Aeolus will aim its Atmospheric Laser Doppler Instrument (ALADIN) into the atmosphere. This is a loftier-power ultraviolet light amplification by stimulated emission of radiation that pulses 50 times per second. Light from the light amplification by stimulated emission of radiation bounces off the atmosphere at various levels and returns to the satellite where it is collected by a 1.5-meter telescope. The light returns with a slightly different frequency, which is known as Doppler shift. By analyzing the difference between the original frequency and the new one, scientists can decide wind speeds.

No previous mission has been able to measure wind speeds across multiple layers of the atmosphere on a global scale. Aeolus information should provide a compelling alternative to conditions airship and airplane flights that can only get together data on limited geographic areas. Aeolus is designed to measure wind speeds from the Earth's surface up to an altitude of 30 kilometers (18.6 miles).

Currently, weather models rely in role upon fake "purlieus weather condition" for wind speed. These figures are based on the smattering of real data bachelor, but Aeolus will offering near existent-time measurements of wind speed across multiple layers of the atmosphere. The Great britain-based European Heart for Medium Range Weather Forecasts is already planning to inject Aeolus information directly into its models.
