# groundAlbedo

A factor that influences the clarity of the simulated sky.

## Declaration

```swift
var groundAlbedo: Float { get set }
```

## Discussion

Discussion This value simulates the amount of light that bounces back up into the sky from the ground. A value of 0.0 produces a clear sky, and values closer to 10 reduce the contrast of the sky, producing a foggy effect.
