Abstract

The rotational Raman LIDAR technique has been used to accurately measure aerosol optical properties such as backscatter coefficient, extinction coefficient, and LIDAR ratio. In the case of the vibrational Raman technique, the <TEX>${\AA}$</TEX>ngstr<TEX>$\ddot{o}$</TEX>om exponent, which has wavelength dependence on the particle properties, is assumed to obtain the extinction coefficient. However, this assumed <TEX>${\AA}$</TEX>ngstr<TEX>$\ddot{o}$</TEX>m exponent can cause systematic errors in retrieving aerosol optical properties. In the case of the rotational Raman technique, the aerosol optical properties can be measured without any assumptions about the <TEX>${\AA}$</TEX>ngstr<TEX>$\ddot{o}$</TEX>m exponent. In this paper, the LIDAR ratio was measured by using the rotational Raman LIDAR and vibrational Raman LIDAR in the troposphere. And, the LIDAR ratios measured by these two methods were compared.
