Abstract
A new inversion algorithm for solving lidar equations by signals at five wavelengths from a Raman lidar was developed. Water vapor mixing ratio, temperature, aerosol scattering ratio and depolarization ratio were retrieved using the lidar data and the algorithm. The obtained profiles show good agreement with radiosonde-observed water vapor and temperature profiles. Backscattering profiles of aerosols up to about 30 km were used to estimate extinction with the optical model of aerosols. The extinction term by Mie and Rayleigh scattering at Raman sifted signals was compensated by these estimated values of aerosol extinction. Atmospheric temperature profile in the free troposphere was calculated by Mie and Rayleigh scattering corrected vibrational Raman scattering of O2 or N2. Observed water vapor and temperature profiles were used to evaluate relative humidity. The algorithm demonstrates the usefulness of vibrational Raman scattering in the lidar observations of the atmosphere.Keywords
