Atmospherics is one of the main simulated systems in [[Stationeers]]. The game world consists of many individual units of atmosphere that interact with each other as well as structures and items that are in contact or intersecting with them.
== Atmosphere Properties == 
Each unit of atmosphere simulates a number of properties, these properties generally change over time as the atmosphere interacts with the surroundings.

=== Contents === 
Each unit of atmosphere contains its' own composition of gasses and liquids represented in quantity by [[moles|mol]]. Common gasses are [[Oxygen]], [[Volatiles]], [[Nitrogen]], [[Carbon Dioxide]] and [[Pollutant]].
[[Water]] is the only liquid currently simulated.
=== Heat Energy ===
Stationeers attempts to simulate thermodynamics by having atmospheres contain heat energy.
The effective temperature of one atmosphere depends on the heat energy relative to the amount of gasses in the atmosphere.
This means that a very small atmosphere can reach very high temperatures with a small amount of added heat.

|}

=== Pressure ===
Pressure is a product of the contents of the atmosphere adjusting by temperature/heat.

== Large Grid Atmosphere == 
The most common type of atmosphere is the large grid atmosphere. In the main game world, each large grid unit (the size of a [[Frame]]) contains one unit of atmosphere.
The atmosphere in one large grid will exchange contents and heat with neighbouring atmospheres in order to equalize their content.
An atmosphere in a vacuum will eventually spread out and dissipate in within a few large grid atmospheres of distance.

== Pipe Network == 
Each individual pipe network is simulated with one atmosphere. If you break up a pipe network with a device such as a pump or valve, you effectively control the interaction of gasses between the two atmospheres.

== Structures == 
Individual structures that contain atmospheres (static tanks, etc) will interact either with a pipe network or directly with the surrounding atmosphere, it depends on the configuration.

== Items == 
Some items in the game contain their own units of atmosphere, such as [[Canister]]s, [[Suit]]s and even the players' [[Lungs]].
Items with atmospheres, just like other atmospheres, can be heated by direct sunlight, leading to canisters bursting by pressure, or fuel autoigniting(exploding) at high pressure/temperature.

Water

== Obtaining ==
You can obtain water by smelting [[Ice (Water)]]

== Usage ==
Water is used to grow plants in a [[Hydroponic Tray]] or a [[Hydroponic Station]]

Water has a specific heat of 72 Joule / mol making it great for cooling.

[[Volatiles]] is a type of gas that can be used in combination with [[Oxygen]] as a combustible [[fuel]]. The main source of Volatiles on most planets is in the form of [[Ice (Volatiles)]] that can be mined on the surface.


Different ratios of Volatiles and Oxygen will produce different temperatures and pressures during combustion. Combustion will create a large amount of Heat, pressure, and [[Carbon Dioxide]]. This reaction is useful inside a [[Furnace]] for smelting ores and creating alloys, but can be catastrophic when inside a [[Canister]] or a room.
Currently as of version v0.1.1089.5513, it is labeled in the atmospheric analyzer as H2, but it is not Hydrogen.<ref>Stationeer's Discord https://discordapp.com/channels/276525882049429515/392785541411635201/393216103284998144</ref>. When burned, it produces heat, [[Pollutant]]s, and [[Carbon Dioxide]] in the following reaction:

2 [Volatiles] + 1 O2 → 3 X + 6 CO2 + Heat

This reaction is inconsistent with volatiles being simple hydrocarbons (too much CO2 is produced), but it may be consistent with more complex organic molecules. The reaction appears to only take place with specific quantities of gas, so Oxygen is often left over even when there is an excess of volatiles.

Volatiles have a specific heat of 20.4 Joule / mol.

Pollutant

[[Pollutant]], also known as X, is produced when smelting certain metals. A concentration of 0.1Mol or greater will cause your suit to warn about pollutants/poison in the air, and it's not recommended to breath air containing Pollutant.

Pollutant has a specific heat of 24.8 Joule / mol, making it great for using as a [[Coolant]].

== About == 
[[Oxygen]], also known as O2, is the basic gas necessary for human survival. It is is released when smelting certain ore (such as [[Ore_(Gold)|gold]]) or by melting [[Ice_(Oxite)|Oxite]]. It is also produced by plants in [[Hydroponic_Tray|hydroponic trays]] or the [[Hydroponic_Station|hydroponics station]] when they photosynthesize.

Oxygen has a specific heat of 21.1 Joule / mol.

== Usage == 
The main usage is in sustaining your life, either in the ambient atmosphere when your helmet is open, or in your suit's oxygen tank. Aside from that it is used for combustion in the [[furnace]] and the [[Gas_Generator|gas generator]].
