This case includes the same setup as case D1 but including spheroidal aerosol particles.

Setup:

• aerosol optical thickness: 0.2
• aerosol optical properties: netCDF,ascii
  The variable “phase” includes the phase matrix, as a function of the scattering angle (variable “theta”). The 4×4 scattering phase matrix for spherical droplets has four non-zero elements, which are stored in the following order: $ P = \begin{pmatrix} P1 & P2 & 0 & 0 \\ P2 & P5 & 0 & 0 \\ 0 & 0 & P3 & P4 \\ 0 & 0 & -P4 & P6 \end{pmatrix} $
  The corresponding Legendre polynomials (“pmom”) and the single scattering albedo (“ssa”) are also included in the file.

The expansion moments over generalized spherical functions for the phase matrix have been provided by S. Korkin and are available here.
