To interpret the data from spaceborn lidar measurements, one must have a basic
understanding of the backscattering of oriented ice particles. The conventional raytracing
method is not applicable to the scattering of light by oriented particles. In this
study, the dipole approximation (DDA) method is employed to the scattering of light
on oriented hexagonal ice columns and plates with various tilting angles. It is found
that the oriented hexagonal ice particles tend to have strong backscattering intensity
with low depolarization ratios which are strongly dependant on the tilting angle of
oriented particles. The present results show that the e ffect of particle orientation
plays an important role in determining the optical properties of ice clouds consisting
of horizontally oriented ice crystals.
