 '''Settings:'''
-* '''Ambient:'''
+* '''Ambient: '''This setting defines a colour and intensity which is added to the lighting that illuminates the atmosphere. While disabled by default, so that only direct and indirect lighting (global illumination) affect the atmosphere, a practical example for using this setting would be to increase the overall brightness of the atmosphere.
-* '''Fake dark power:'''
+* '''Fake dark power: '''This setting is intended for planetary orbit views, as a way to artificially darken the atmosphere if it appears too bright, especially near the terminator, the line that divides the daylit side and the dark night side of a planetary body. Higher values increase the darkness of the atmosphere.
-* '''Fake dark sharpness:'''
+* '''Fake dark sharpness: '''This setting is intended for planetary orbit views, as a way to artificially adjust the falloff of the terminator line on the atmosphere. In order for this setting to have an effect, the "Fake dark power" must be greater than 0. Higher values result in a quicker falloff or sharper transition.
-* '''Bluesky density colour:'''
+* '''Bluesky density colour: '''This setting provides an alternative method of control over the bluesky component of the atmosphere.  It depends upon the chosen colour value to the right of its slider and the relationship between the “Bluesky additive” and “Redsky decay” settings found on the Main tab.  Changing this setting also changes the “Bluesky additive” setting on the Main tab.  If the “Bluesky density colour” is black, then the “Bluesky horizon colour” on the Main tab may also be 0, because the atmosphere has no density.  Likewise, if the “Bluesky additive” is 0, the “Bluesky horizon colour” should also be 0 because there is nothing to add light to in the atmosphere.  Lowering the value thins out the blue component of the sky, visually reducing the blue colour saturation in the atmosphere and biasing it towards “cooler” colour values.
 * '''Redsky decay colour:'''
-* '''Ozone factor: '''
+* '''Ozone factor: '''This controls the absorption strength of a simulated ozone layer in the atmosphere, which absorbs red and green light to produce bluer skies especially during sunrise and sunset. It strongly affects views from high altitude too. The height profile of the ozone layer is hard-coded to simulate an average Earth atmosphere, but automatically scales in proportion to the "Bluesky exp height" if it varies from the default value of 8000 metres. When “Bluesky exp height” is at the default value the ozone layer occurs between 12 kilometres and 63 kilometres, peaking in density at around 20 kilometres. Density also changes in proportion to bluesky density to produce realistic results in a variety of setups.The default project and newly created planet atmospheres have the ozone factor value set to 0.5.
