==== Case D6: Ocean surface ====

This case includes the same setup as case D1 but including an ocean surface (reflectance matrix). 

//Setup://
  * Ocean reflectance matrix by Mishchenko's code [[http://www.giss.nasa.gov/staff/mmishchenko/ftpcode/ocean.shadow.f|ocean.shadow.f]] (uses anti-clockwise convention for azimuth angle!)
  * refractive index of water (1.33 + 0i)
  * wind speed 2m/s
  * scattering optical thickness (Rayleigh) of layer: 0.1
  * no molecular absorption
  * Rayleigh depolarization factor: 0.03
  * Earth radius: 6371 km
  * Thickness of layer: 120 km

  * Sun-observer geometries as defined in general settings:
      * //viewing zenith angles// (deg): [0, 9, 18, 26, 34, 41, 48, 54, 60, 65, 70, 74, 78, 81, 84, 86, 88, 89, 90] (up-looking at bottom of atmosphere, down-looking at top of atmosphere]
      * //viewing azimuth angles// (deg): 0-180, 10° increment 
      * //solar zenith angles// (deg): [30, 60, 80, 87, 90, 93, 96, 99]
      * //solar azimuth angle// (deg): 0
      * //sensor altitude// (km): 0, 120
