===== Retrieval of NO2 for scenes including realistic clouds =====

==== Test case ====

  * Subdomain of ICON, approx. 350x350km²
  * Resolution of cloud data approx. 1.2x1.2km², 296x276x110 grid boxes
  * Simulations performed for pixel size of 7x7km² (50x48 pixels)

=== Reflectance and box-AMF simulation ===

  * wavelength: 550nm
  * US standard atmosphere
  * SZA: 30°, SAA: 25°
  * Viewing direction: nadir
  * surface albedo: 0.05
  * clouds from ICON simulation
