==== Case A2: Rayleigh atmosphere with Lambertian surface ==== 

//Setup://
  * similar to case A1, with small modifications
  * surface albedo: 0.3
  * optical thickness: 0.1
  * Rayleigh depolarization factor: 0.03
  * transmittance at bottom and reflectance at top of layer	
  * solar zenith angle //sza//: 50°
  * 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° - 180°, 5° increment	     
  
 
//Output format://
  * The output should be provided in the same format as for case A1 ([[intercomparisons:a1_rayleigh|Rayleigh scattering]]).
