The most important factor of a planet's atmosphere is simply having one. Specifically, having air pressure similar to Earth's 100,000 pascals (Pa) at sea level. From orbit, your planet's atmospheric pressure will affect the visibility of the air above the surface: too thin and it will be invisible, too thick and it will be opaque.
Terraforming[]
A minimum amount of Pressure is necessary to build a supply of Oxygen (1 Pa) and water (600 Pa).
Changing Pressure also affects accumulation of Temperature. "Atmosphere Thinning" causes loss of heat, while "Atmosphere Thickening" causes increase of heat. Increasing Pressure will create the status of Temperature that is "Retained by Atmosphere". That is the greenhouse effect. The Temperature increases by 0.046 mK for every pascal.
The state of Water is affected by Pressure. At less than 600 Pa, all water is held as vapor or ice even though the temperature is not at the full ice or vapor point. When 600 Pa is breached (and the temperature is within the liquid range (between 200,500 and 399,500 mK), a percentage of the vapor/ice will turn into liquid water instantly, which can destroy every outpost and city that happens to be below the sea-level.
Habitability for plants and microbes to grow on a planet's surface requires an atmospheric pressure of 10,000 to 190,000 Pa. Habitability for animals and humans outside of a Habitation building is a narrower range between 50,000 and 150,000 Pa.
Pressure takes the least amount of time and effort to increase in the game, as it can less than one real life day to use a non-upgraded Atmogen Suite to get the pressure right for human and plant life, whereas there are a lot of worlds with high pressure, such as Venus and Vaalbara, which take a lot longer to terraform because of the high pressure, with the problem of facilities being crushed to boot.
Pressure (Pa) | Effect on world |
---|---|
>0 | Clouds start forming, but cannot be seen until Pressure is higher. |
>42,000 | The atmospheric halo can be seen. |
>110,000 | Clouds start to turn opaque and expand. |
150,000 | The atmospheric halo is at its thickest—above that point, it will slowly fade. |
>190,000 | The atmospheric halo cannot be seen anymore because of the thick clouds. |
>200,000 | The surface is hidden by the clouds. |
Governors[]
Frank M. Srikar, Ayzia Aoyama and Nubia Matiba have effects that can help your facilities reduce your world's pressure levels faster.
Elle De León, Yusuf Mardin and David Munoz have effects that can help your facilities increase your world's pressure levels faster.
