As the key to renewable energy, the accurate assessment and efficient utilization of wind energy are crucial to promoting energy transformation. However, traditional assessment methods are often limited in data accuracy and resolution in complex terrain and variable wind speed conditions. Lidar technology, with its excellent 3D wind field measurement capability, significantly improves the assessment accuracy and efficiency, and is suitable for flat area, complex terrain and offshore wind resource survey, wind turbine power curve test, remote wind tower scanning, wind shear analysis, wind turbine wake test and pitch control, etc. It helps wind farm site selection optimization, component life extension and operational efficiency improvement, and provides a comprehensive solution for wind power users.
With the frequent occurrence of extreme weather, the development of meteorological operations and the increasing demand for weather forecasting services, while refined and highly accurate forecasts and service products cannot be separated from the full application of high temporal and spatial resolution products. Lidar technology, with its unique advantages, shows great potential in weather monitoring and forecasting. By emitting laser beams and receiving their reflected signals, the technology is able to detect various parameters in the atmosphere with all-weather and high accuracy, including wind field, low-altitude wind shear, atmospheric turbulence, temperature and humidity profiles, and the inversion of parameters of aerosol optical properties, etc., which provides rich and refined data support for meteorological operations.
Lidar technology is widely used in the field of environmental monitoring. In pollutant monitoring, aerosol lidar accurately captures aerosol particles, ozone lidar monitors ozone concentration in real time, and CO₂ lidar reveals the distribution of carbon dioxide, together building a comprehensive pollutant monitoring network. Combined with the monitoring of meteorological conditions such as wind speed, wind direction, temperature and humidity, Lidar technology can also provide a scientific basis for exploring the causes of pollutants, their transformation mechanisms and diffusion paths, and for improving air quality.
Tail vortices generated by aircraft wingtips and low-level windshear at airports are meteorological factors affecting the safety of aircraft flights, especially the final approach and initial takeoff are the most dangerous flight phases, and the tail vortices and windshear are invisible to pilots and air traffic controllers, which can lead to air crashes if they cannot react in time. High temporal and spatial resolution LiDAR can be applied to aviation meteorological wind measurement needs, monitoring and identifying low-level windshear and aircraft tail vortices at airports, to ensure safe landing and flight spacing of aircraft, to improve the transportation capacity of airports during peak periods, and to provide users with a full range of customized services.
