## <MapboxGL.SkyLayer />
### SkyLayer is a spherical dome around the map that is always rendered behind all other layers

### props
| Prop | Type | Default | Required | Description |
| ---- | :--: | :-----: | :------: | :----------: |
| id | `string` | `none` | `true` | A string that uniquely identifies the source in the style to which it is added. |
| sourceID | `string` | `MapboxGL.StyleSource.DefaultSourceID` | `false` | The source from which to obtain the data to style.<br/>If the source has not yet been added to the current style, the behavior is undefined. |
| aboveLayerID | `string` | `none` | `false` | Inserts a layer above aboveLayerID. |
| belowLayerID | `string` | `none` | `false` | Inserts a layer below belowLayerID |
| layerIndex | `number` | `none` | `false` | Inserts a layer at a specified index |
| filter | `array` | `none` | `false` | Filter only the features in the source layer that satisfy a condition that you define |
| style | `union` | `none` | `false` | Customizable style attributes |

___

#### visibility
Name: `visibility`

#### Description
Whether this layer is displayed.

#### Type
`enum`
#### Default Value
`visible`

#### Supported Values
**visible** - The layer is shown.<br />
**none** - The layer is not shown.<br />


___

#### skyType
Name: `skyType`

#### Description
The type of the sky

#### Type
`enum`
#### Default Value
`atmosphere`

#### Supported Values
**gradient** - Renders the sky with a gradient that can be configured with `sky-gradient-radius` and `sky-gradient`.<br />
**atmosphere** - Renders the sky with a simulated atmospheric scattering algorithm, the sun direction can be attached to the light position or explicitly set through `sky-atmosphere-sun`.<br />


#### Expression

Parameters: `zoom`

___

#### skyAtmosphereSun
Name: `skyAtmosphereSun`

#### Description
Position of the sun center [a azimuthal angle, p polar angle]. The azimuthal angle indicates the position of the sun relative to 0° north, where degrees proceed clockwise. The polar angle indicates the height of the sun, where 0° is directly above, at zenith, and 90° at the horizon. When this property is ommitted, the sun center is directly inherited from the light position.

#### Type
`array<number>`

#### Units
`degrees`

#### Minimum
`0,0`


#### Maximum
`360,180`

#### Expression

Parameters: `zoom`

___

#### skyAtmosphereSunIntensity
Name: `skyAtmosphereSunIntensity`

#### Description
Intensity of the sun as a light source in the atmosphere (on a scale from 0 to a 100). Setting higher values will brighten up the sky.

#### Type
`number`
#### Default Value
`10`

#### Minimum
`0`


#### Maximum
`100`


___

#### skyGradientCenter
Name: `skyGradientCenter`

#### Description
Position of the gradient center [a azimuthal angle, p polar angle]. The azimuthal angle indicates the position of the gradient center relative to 0° north, where degrees proceed clockwise. The polar angle indicates the height of the gradient center, where 0° is directly above, at zenith, and 90° at the horizon.

#### Type
`array<number>`
#### Default Value
`[0,0]`

#### Units
`degrees`

#### Minimum
`0,0`


#### Maximum
`360,180`

#### Expression

Parameters: `zoom`

___

#### skyGradientRadius
Name: `skyGradientRadius`

#### Description
The angular distance (measured in degrees) from `skyGradientCenter` up to which the gradient extends. A value of 180 causes the gradient to wrap around to the opposite direction from `skyGradientCenter`.

#### Type
`number`
#### Default Value
`90`

#### Minimum
`0`


#### Maximum
`180`

#### Expression

Parameters: `zoom`

___

#### skyGradient
Name: `skyGradient`

#### Description
Defines a radial color gradient with which to color the sky. The color values can be interpolated with an expression using `skyRadialProgress`. The range [0, 1] for the interpolant covers a radial distance (in degrees) of [0, `skyGradientRadius`] centered at the position specified by `skyGradientCenter`.

#### Type
`color`
#### Default Value
`interpolate,linear,sky-radial-progress,0.8,#87ceeb,1,white`


#### Expression

Parameters: `sky-radial-progress`

___

#### skyAtmosphereHaloColor
Name: `skyAtmosphereHaloColor`

#### Description
A color applied to the atmosphere sun halo. The alpha channel describes how strongly the sun halo is represented in an atmosphere sky layer.

#### Type
`color`
#### Default Value
`white`


___

#### skyAtmosphereColor
Name: `skyAtmosphereColor`

#### Description
A color used to tweak the main atmospheric scattering coefficients. Using white applies the default coefficients giving the natural blue color to the atmosphere. This color affects how heavily the corresponding wavelength is represented during scattering. The alpha channel describes the density of the atmosphere, with 1 maximum density and 0 no density.

#### Type
`color`
#### Default Value
`white`


___

#### skyOpacity
Name: `skyOpacity`

#### Description
The opacity of the entire sky layer.

#### Type
`number`
#### Default Value
`1`

#### Minimum
`0`


#### Maximum
`1`

#### Expression

Parameters: `zoom`
___

#### Name

`skyOpacityTransition`

#### Description

The transition affecting any changes to this layer’s skyOpacity propery.

#### Type

`{ duration, delay }`

#### Units
`milliseconds`

#### Default Value
`{duration: 300, delay: 0}`
