Abstract

The aerosol and cloud color ratio from 1064 nm and 532 nm MIE LIDAR measurements was determined in this work. MIE LIDAR data was obtained for the two wavelengths using LabView VIs developed by our group. The color ratio was derived from the ratio of 1064 nm over 532 nm aerosol backscatter coefficients. Aerosol backscatter coefficients were computed using Fernald's inversion algorithm where the extinction-to-backscatter ratio (S_a) was kept at 30 sr for all altitudes. This paper presents data for June 21, 2006. Results show the capability of the color ratio to differentiate between clouds and aerosols.
