Fields
| Field | Type | Required | Default | Allowed values | Description |
|---|---|---|---|---|---|
preset | AtmospherePreset | no | earth-clear, hazy, polluted, stylised | Named atmosphere: earth-clear (the default: clean air), hazy (three times the aerosols), polluted (dense absorbing aerosols, a brown low-contrast sky) or stylised (bluer and more saturated than Earth). | |
planetRadiusKm | number | no | Radius of the planet, kilometres, within 100..100000. Default 6360 (Earth). A small planet curves its horizon sooner, which a large world notices. | ||
groundAlbedo | number | no | 0 | How much light the planet's surface reflects, within 0..1. Default 0.3. It lights the sky from below and is the ground seen past the level's edge. | |
haze | number | no | 1 | Scale on the preset's aerosols (Mie scattering), within 0..10. Default 1; 0 is air with no aerosols, 3 a hazy day. | |
visibilityKm | number | no | Meteorological visibility, kilometres, within 0.1..1000: how far a dark object can be seen against the horizon sky. It sets the air's total extinction at ground level (Koschmieder: 3.912 / visibility per km, of which Rayleigh scattering is the molecular share and the aerosols the rest) and overrides haze. Absent keeps the preset's aerosols (earth-clear is about 217 km); 50 is a clear day, 25 a typical one, 10 a hazy one, 1 fog. |
