The LGJ-05 temperature and humidity Raman lidar uses the Raman-Mie scattering principle.Emitted laser pulses interact with atmospheric molecules and aerosols, generating vibrational-rotational Raman scattering fromn itrogen and water vapor. By analyzing their Raman signals, the system retrieves atmospheric water vapor mixing ratios and temperature profiles.
Parameters
Temperature, water vapor mixing ratio, relative humidity, aerosol extinction coefficient, aerosol backscattering coefficient, cloud information, optical thickness, boundary layer height, etc.
· Higher accuracy with the molecular Raman algorithm (no lidar ratio assumption).
· Suitable for calibrating regional Mie scattering lidar.
· High-power lasers and large telescopes improve signal strength and range.
