10km Wind Lidar for Aviation Windshear Detection
WINDVIEW20 (10km) is a new-generation of remote sensing lidar, designed by Everise. It’s a good tool for measuring the atmospheric wind profiles-wind speed/wind direction for multiple detection purposes like wind energy source, aviation safety, climate-meteorology research etc.The max. detection range of this powerful doppler wind lidar can be up to 10km.
It is widely used to monitor and forecast wind shear and guarantee the aviation security. The atmospheric conditions such as wind shear, micro burst, gust and turbulence directly affect aircraft safety, especially when the plane takes off or lands. Even in clear and dry weather, dramatic changes of wind direction will bring serious challenges to pilots, which may leads the aircraft to sink suddenly or run out of the airstrip. It detects wind shear in the scanning range by real-time scanning all potential hazardous areas within the airport airspace and sends automatic alerts to air traffic controllers so that pilots can make corresponding decisions on flight safety.
4km Wind Lidar for Environmental & Meteorological Applications
WINDVIEW12 is a state-of-art Doppler Wind Lidar for 3D measuring the atmospheric wind profiles with wind speed/wind direction for multiple detection purposes such as air quality analysis, wind energy resource assessment, aviation windshear detection, climate-meteorology research etc. The max. detection range of this powerful doppler wind lidar can be up to 4~5km for most of time.
The wind condition not only directly affects aircraft safety, but also directly affect the wind energy on the earth. In contrast to conventional power plants, the production of wind farms depends on meteorological conditions, particularly the magnitude of the wind speed, which can not be directly influenced by human intervention. Thus, in wind energy systems, wind speed plays the most important role when the energy produced by a wind energy conversion system is assessed.
The wind condition will also affect the atmospheric pollution’s transmission path and how long & how far will the pollution goes. It’s helpful to track pollution source and predict pollution weather. Other weather data and geographic information can also be considered as the influence factors.
