Temperature and Humidity Raman Lidar
DSL-THR
Based on the detection principles of rotational Raman and vibrational Raman frequency shifts, the temperature and humidity Raman lidar can realize refined detection of temperature, humidity and aerosols in the planetary boundary layer, troposphere and even the lower stratosphere. It can be used to study the state variations within the atmospheric boundary layer, and is of great significance for researches on solar radiation, heat transfer in geodynamics, interpretation of global warming phenomena, improvement of meteorological forecast accuracy, especially urban meteorological variations. The lidar can monitor parameters such as the height and thickness of temperature inversion layers, providing scientific data support for studying the impacts of temperature inversion layers on the environment and transportation.
