==== Case A6: Ocean surface ====

//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
  * mean square slope parameter of rough ocean surface 0.00534*W, where W is wind speed (m/s)
  * scattering optical thickness (Rayleigh) of layer: 0.1
  * no molecular absorption
  * Rayleigh depolarization factor: 0.03
  * transmittance at bottom and reflectance at top of layer
  * solar zenith angle //sza//: 45°
  * solar azimuth angle //saa//: 0°
  * viewing zenith angles 
    * at bottom: //vza//: 0° - 80°, 5° increment
    * at top:    //vza//: 100° - 180°, 5° increment
  * viewing azimuth angle //vaa//: 0° - 360°, 5° increment	     

//Output format://
  * The output should be provided in the same format as for case A1 ([[intercomparisons:a1_rayleigh|Rayleigh scattering]]).
