Aerosol lidar is a type of lidar (light detection and ranging) system specifically designed to measure the properties of aerosols in the atmosphere. Aerosols are tiny solid or liquid particles suspended in the air, such as dust, smoke, sea salt, and pollutants. These particles play a significant role in atmospheric processes, affecting climate, air quality, and visibility.

Aerosol lidar systems emit laser pulses into the atmosphere and detect the light that is scattered back by aerosol particles. The intensity and characteristics of the backscattered light provide information about the concentration, size, shape, and optical properties of the aerosols. Different wavelengths of light can be used to probe different aerosol types and their vertical distribution.

Common applications of aerosol lidar include monitoring atmospheric pollution, studying the transport of dust and volcanic ash, understanding cloud formation processes, and assessing atmospheric radiative transfer. These measurements are crucial for climate modeling, weather forecasting, and air quality management. Mobile lidar systems can also be deployed to map aerosol distributions over wider areas or to investigate localized pollution events. The data generated by aerosol lidar contributes to a better understanding of atmospheric dynamics and its impact on human health and the environment.
