AB: The effective Mueller matrix is obtained using a Monte Carlo method developed by Kattawar, Tynes and Adams. Five ice crystal habits are considered with varying percentages within ice clouds (obtained from previous studies) in the tropics and middle latitudes. Averaging of the single scattering properties, including size distribution, of these habits at wavelengths 0.532 um and 1.064 um is performed using Yang and Liou's improved geometrical-optics method. Sensitivity of the effective Mueller matrix to ice crystal habit is investigated using the radiative transfer code.
