Abstract

A rotational Raman lidar system has been designed and tested for observations of meteorological parameters, such as wavelength dependent aerosol backscattering coefficients and atmospheric temperature profiles. We have designed a two wavelength rotational Raman lidar system that has 2 channels at 355 nm for observing the aerosol backscattering coefficients and 3 channels for the temperature profiles and aerosol backscattering coefficients. Form our preliminary performance test, we could not find any leakage of the elastic signal into the rotational signal, not even under cloudy conditions. Using this system, we successfully obtained the relative temperature and wavelength dependent aerosol backscattering coefficient profiles for cloudy conditions. The wavelength dependent aerosol backscattering coefficients increased from 0.01 to 8 for liquid droplets when their size increased. Also, a relative temperature profile was successfully obtained for cloudy and clean conditions for distance up to 7 km within 30 minute.
