The Atmospheric Effects Render Element stores only atmospheric or volumetric participating media such as fog or Aerial Perspective.  This render element can then be used to enhance or color-correct just the atmospheric component of the image during the compositing process.

When atmospheric effects or fog is included in a scene, they will render into the Beauty (RGB color) channel, and should also be output as the atmosphere channel for compositing use.
