FRENCH GUIANA: A satellite using laser technology capable of measuring winds around the globe has been launched into polar orbit on a rocket.<\/p>\n
<\/p>\n
The European Space Agency\u2019s (ESA\u2019s) Vega rocket carrying the Earth Explorer 1.36-tonne Aeolus satellite lifted off from Europe\u2019s spaceport in French Guiana on the north-east coast of South America on 22 August.<\/p>\n
It carries the Aladin instrument which includes laser technology that beams down pulses of ultraviolet light into the atmosphere to profile the earth\u2019s winds \u2013 a new approach to wind measurement from space, the ESA stated.<\/p>\n
Aladin profiles the lowermost 30km of the atmosphere, giving scientists wind speed data in near-real time.<\/p>\n
The agency added that this will help scientists better understand how the wind influences the exchange of heat and moisture between the Earth\u2019s surface and the atmosphere \u2013 important aspects for understanding climate change.<\/p>\n
Aeolus will also help to create better wind profiles and improve weather forecasting, the ESA added.<\/p>\n
