Define a MYSTIC 3D water cloud input file.
mc_wcloud_file file
The expected format of the cloud file is:
Nx  Ny  Nz  gspec flag
dx  dy  z(1) z(2) ... z(n)
ix  iy  iz  ext  g     ssa  (if flag == 1)
ix  iy  iz  ext  reff       (if flag == 2)
ix  iy  iz  LWC  reff       (if flag == 3)
where Nx, Ny and Nz are the number of grid boxes in x, y, and z-direction. gspec and wspec are parameters, which determin the format of the 3rd and following lines. In the second line dx and dy are the sizes of the boxes in x- and y-direction in km. In the third and following lines the indices ix, iy, and iz specify cloudy pixels. The optical properties of the cloud, are given by the other parameters in the line, where ext is the extinction coefficient [1/km], g the asymmetry parameter, reff the effective radius [micrometer], and ssa the single scattering albedo. The conversion from microphysical to optical properties is defined by wc_properties (identical to the 1D case). For more information please consult the MYSTIC documentation, doc/README.MC.
