==== Case D6: Mixed particle types ====

This case includes the same setup as case D1 but including a mixture of molecules, spherical and spheroidal aerosol particles. The aerosol optical properties are the same as defined in cases D3 and D4. 

//Setup://

  * Molecular optical thickness: 0.5      
  * spherical aerosol optical thickness: 0.2
  * spheroidal aerosol optical thickness: 0.3
  * no molecular absorption
  * Earth radius: 6371 km
  * Thickness of layer: 100 km

  * D6_1: Twilight radiance field (normalized to incident irradiance) at the bottom of the layer:
    * sun position: //sza//:92°, //saa//:65°
    * viewing zenith angles: //vza//: 0° - 90°, 5° increment (up-looking)
    * viewing azimuth angles: //vaa//: 0° - 360°, 5° increment	     

  * D6_2: Limb radiance at top of atmosphere for 20 km tangent height
    * viewing zenith angle at TOA: //vza//: 81.9°
    * viewing azimuth angle at TOA: //vaa//: 30°
    * solar zenith angles: //sza//: 0° - 90°, 5° increment 
    * solar azimuth angles: //saa//: 0° - 360°, 5° increment
