Properties of cirrus cloud by a three wavelength Raman Mie Polarization lidar: observation and model match

A three-wavelength Raman Mie Polarization Lidar has been developed for cloud and aerosol optical properties measurement. The Nd-YAG laser is employed as emitting source and six channels are used for detecting back-scattering signals from atmosphere aerosol and cloud including 1064 and 355 nm Mie, 607 and 386 nm N2 Raman, two 532 nm Orthogonal Polarization channels. The measured data are used for investigating the cirrus properties including cloud optical depth, polarization ratio, color ratio and lidar ratio. And these results are matched with the microphysical model suggested.
