=====Optical properties of liquid water for various effective radii=====

  *Plot gamma size distributions with an effective variance of 0.1 for effective radii in the range from 1 to 80 µm. 

  *Perform Mie calculations for wavelengths from 100 to 10000 nm for gamma distributions with effective radii from 1 to 20. Plot the real and the imaginary part of the refractive index, the extinction coefficient, the asymmetry parameter, and the single scattering albedo.

Important: Please change in mie.c line 674 to
   radmax = 5.00 * input.r_eff_max; 
and line 684 to
   dx=0.03; 
and recompile in order to speed up the calculations!

Here is an input file for a Mie calculation including a size distribution (please see the libRadtran user manual for detailed description of the options):

<file bash mie.inp>
mie_program MIEV0     # use Mie program MIEV0 by Wiscombe
refrac water          # use refractive index of water
r_eff 10              # Specify effective radius 
wavelength  wvl.dat   # File including wavelengths to be calculated
distribution GAMMA 7  # Specify gamma distribution with veff=1/(GAMMA+3) 
</file>

A file including the wavelengths for the calculations: {{:teaching:radiative_transfer:wvl.dat|}}

The mie tool is executed as follows:

   mie < mie.inp > mie.out

Describe the results!
