Measurement of Aerosol Parameters with Altitude by Using Two Wavelength Rotational Raman Signals

Open Access Open Access

Abstract

Aerosol size distribution provides good information for predicting weather changes and understanding cloud formation. Aerosol extinction coefficient and backscattering coefficient are measured by many scientists, but these parameters depend not only on aerosol size but on aerosol concentrations. An algorithm has been developed to measure aerosol parameters such as <TEX>${\AA}$</TEX>ngstr<TEX>$\ddot{o}$</TEX>m exponent, color ratio, and LIDAR ratio without any assumptions by using two wavelength rotational Raman LIDAR signals. These parameters are good indicators for the aerosol size. And we can find <TEX>${\AA}$</TEX>ngstr<TEX>$\ddot{o}$</TEX>m exponent, color ratio, and LIDAR ratio under various weather conditions. Finally, it can be seen that the <TEX>${\AA}$</TEX>ngstr<TEX>$\ddot{o}$</TEX>m exponent has an inverse relationship to the particle size of the aerosol and the color ratio is linearly dependent on the aerosol size. An <TEX>${\AA}$</TEX>ngstr<TEX>$\ddot{o}$</TEX>m exponent from 1.2 to 3.1, a color ratio from 0.28 to 1.04, and a LIDAR ratio 66.9 sr at 355 nm and 32.6 sr at 532 nm near the cloud were obtained.
