Flying under Aeolus

Following the launch of Aeolus on 22 August 2018, scientists have been busy fine-tuning and calibrating this latest Earth Explorer satellite. Aeolus carries a revolutionary instrument, which comprises a powerful laser, a large telescope and a very sensitive receiver. It works by emitting short, powerful pulses – 50 pulses per second – of ultraviolet light from a laser down into the atmosphere. The instrument then measures the backscattered signals from air molecules, dust particles and water droplets to provide vertical profiles that show the speed of the world’s winds in the lowermost 30 km of the atmosphere. These measurements are needed to improve weather forecasts. As part of the working being done to calibrate this novel mission, scientists have been taking similar measurements from an aircraft carrying an airborne version of Aeolus’ instrument. The pilot flies the plane under the satellite as it orbits above so that measurements of wind can be compared.

  1. A sincronização perfeitta …terra/ar …em evidência o algoritmo!! Um projecto importante dado que os ventos são importantes na constância do tempo e prever os ventos que se tem alterado … estando ieste projecto votado para o sucesso e os ventos correm e num ápice mudam de feição. .deixando a devastação!! O Eolo está cada vez mais imprevisível não e?

  2. May I use a portion of this video (only a few seconds) to be used in my video as a visual illustration, I will include credit in the video and link in my video description.
