Its structure consists of the troposphere, stratosphere, mesosphere, and ionosphere. Changing the composition of the atmosphere also influences the temperature. Atmospheric circulation (weather) is driven by seasonally changing deposition of sunlight. Many longer term climate variations, such as the ice ages, are related to changes i

The pressure P is sometimes called the absolute pressure; this is to distinguish it from the gauge pressure Pg, which is the difference between absolute pressure and atmospheric pressure Pa:Pg=P−Pa.
