Query: Geometric modeling of aerosol surface roughness and numerical simulation
  of its impact on aerosol optical properties   A stochastic method is introduced for geometric modeling aerosol surface
roughness with random field and discrete differential geometry theory. Optical
scattering properties are computed for randomly oriented spheroidal particles
with uniformly random surface roughness. Invariant imbedding T-Matrix and
geometric optics method are applied to compute light scattering properties of
aerosol particles covered from Rayleigh to geometric optics region. We
simulatied scattering phase matrix of model particles, better performace is
obtained than smooth particles. We aslo introduce introduce entropy and
relative entropy as measures to distinguish the optical scattering similarities
between different particles.
