You can create these Shaders in the SHOP. Environment includes Atmosphere nodes and Background nodes.

Atmosphere

There are two types of atmosphere in Arnold, fog, and atmosphere_volumeFog simulates the effect of light scattering, which causes more distant objects to appear lower in contrast, especially in outdoor environments. Atmosphere_volume simulates light scattered by a thin, uniform atmosphere. It produces shafts of light and volumetric shadows cast from geometric objects. 

It is not possible to render both fog and atmosphere_volume in the same scene.

Background

Background nodes include the Sky shader, but a Flat could also be assigned here. 

Adding An Environment to a Scene

To add some atmosphere or background to a scene, first, create a Shader in the SHOP. Double click to enter the VEX Builder and Tab-type (Custom > Fog / Atmosphere Volume / Sky). Connect the output of the atmosphere nodes to the atmosphere parameter of the environment output node and the sky node to the background parameter.

atmosphere_volume & background -> OUT_environment inside an Arnold Shader Network

 

In the Main tab of a Render Output, connect the required Shaders to the Environment parameter.
