Doppler Lidar

Doppler lidar is a technology that uses laser light to measure the movement of particles in the air, such as wind, pollution, or aerosols. It works by emitting a laser beam into the atmosphere; when the light hits moving particles, it reflects back with a slight shift in frequency, known as the Doppler effect. By analyzing this shift, the system can determine the speed and direction of airborne particles, providing precise wind measurements over large areas. This makes Doppler lidar valuable for weather forecasting, climate research, and monitoring air quality.
