#### new Cesium.SkyAtmosphere(ellipsoid)
Scene/SkyAtmosphere.js 64

  An atmosphere drawn around the limb of the provided ellipsoid. Based on Accurate Atmospheric Scattering in GPU Gems 2.

  This is only supported in 3D. atmosphere is faded out when morphing to 2D or Columbus view.

### Members

#### readonlyellipsoid : Ellipsoid
Scene/SkyAtmosphere.js 126

#### show : Boolean
Scene/SkyAtmosphere.js 73

  Determines if the atmosphere is shown.
  Default Value: `true`

### Methods

#### destroy() → undefined
Scene/SkyAtmosphere.js 245

  Destroys the WebGL resources held by this object. Destroying an object allows for deterministic release of WebGL resources, instead of relying on the garbage collector to destroy this object.
  Once an object is destroyed, it should not be used; calling any function other than `isDestroyed` will result in a `DeveloperError` exception. Therefore, assign the return value (`undefined`) to the object as done in the example.

  ##### Returns:

  ##### Throws:

  - DeveloperError : This object was destroyed, i.e., destroy() was called.

  ##### Example:

      skyAtmosphere = skyAtmosphere && skyAtmosphere.destroy();

  ##### See:

  - SkyAtmosphere#isDestroyed

#### isDestroyed() → Boolean
Scene/SkyAtmosphere.js 223

  Returns true if this object was destroyed; otherwise, false.
  If this object was destroyed, it should not be used; calling any function other than `isDestroyed` will result in a `DeveloperError` exception.

  ##### Returns:

  `true` if this object was destroyed; otherwise, `false`.
