Observer stands at 3000m, view angle is 50 degrees. Zoom of h3000-v70. The sun is at azimuth 180 degrees, i.e. it's midday, where the height of the sun above the horizon is 60 degrees. The valley itself points 40 degrees to the north, and this is, where the observer is looking at. When the cloud scale lenght is changed to 3E-4, image cl-4-6km-S3E-4-D3E-3 is resulting.
