ECMWF Starts Assimilating Aeolus Wind Data

Aeolus is a polar-orbiting satellite which sends laser light into the atmosphere and measures the backscatter to obtain information on winds in the direction perpendicular to the satellite’s path. (Credit: ESA/ATG Medialab)

READING, England (ECMWF PR) — The European Centre for Medium-Range Weather Forecasts (ECMWF ) started assimilating wind data from the European Space Agency’s ground-breaking Aeolus satellite operationally on 9 January 2020 after tests showed that they significantly improve weather forecasts.

KOUROU, French Guiana (Arianespace PR) — Arianespace marked another mission accomplished for the Earth’s sustainable development as its light-lift Vega vehicle successfully orbited Europe’s Aeolus – the first satellite designed to profile wind profiles on a global scale.

Lifting off from the Spaceport’s Vega Launch Complex at 6:20:09 p.m. local time in French Guiana – the planned precise moment of launch – Vega lofted its passenger during a flight lasting just under 55 minutes, with Aeolus placed into a Sun-synchronous orbit.

Built by Airbus Defence and Space, the satellite carries a laser Doppler wind LIDAR (Light Detection and Ranging) system called Aladin that will probe the lowermost 30 km. of the atmosphere in measuring winds around the Earth.
