Options: Atmosphere
Geostationary rendering - i.e., not providing the reproject mode - allows for basic atmospheric effects to be added to the image.
For historical reasons, atmosphere is added via the -h / --haze command-line argument, and can be between 0.0 (no atmosphere) and 1.0 (full atmosphere). To adjust the atmospheric opacity, use the -O / --hazeopacity argument. This also has a range between 0.0 (transparent) and 1.0 (opaque).
The gradient used to create the effect is defined in Gradients\Atmosphere.json.
Examples, with no atmosphere and maximum atmosphere:
sanchez -o output -s sample-images -h 1.0 -O 0.5
