Two of the largest airports in Germany have installed Lockheed Martin-made Doppler lidar systems that work to monitor atmospheric conditions and measure wind speed and direction along airport flight paths.
The German Weather Service sought to follow the International Civil Aviation Organization’s recommendations on providing information regarding wind shear that could affect aircraft on approaches or take-off paths, Lockheed said Thursday.
Airports in Frankfurt and Munich use Lockheed’s WindTracer as part of a wind shear alert system, which contains both the lidar and a weather radar.
Dr. Michael Margulis, director of WindTracer Programs at Lockheed, said airports use both weather radar and WindTracer to track wind hazards.
WindTracer helps airport personnel track winds and wakes for more than one million flights and is also used at airports in locations such as Hong Kong, Tokyo, Osaka, London, New York, San Francisco and Las Vegas.
The lidar transmits pulses of infrared laser light that reflect off of aerosol particles in the atmosphere that move by wind, which alters the frequency of the light that travels to the system.
WindTracer processes the return signal and aims to automatically detect potentially hazardous winds during severe weather.
