Atmosphere Classifications -> Summary Synopsis Paragraphs
Atmo Code | Statement (Summary Synopsis Paragraph) | Remarks |
---|---|---|
Vacuum Atmosphere (Atmo Type: 0) | World has a pressure of less than 0.001 atmospheres, which requires the use of a vacc suit. | Example: Terran Moon |
Trace Atmosphere (Atmo Type: 1) | World has a pressure of less than 0.1 atmospheres, which requires the use of a vacc suit.
|
Example: Mercury (world) |
Very Thin Atmosphere & Tainted Atmosphere (Atmo Type: 2) | World has a pressure of 0.10 to 0.42 atmospheres.
|
Example: Very high altitude Terra
|
Very Thin Atmosphere (Atmo Type: 3) | World has a pressure of 0.10 to 0.42 atmospheres.
|
Example: Very high altitude Terra
|
Thin Atmosphere & Tainted Atmosphere (Atmo Type: 4) | World has a pressure of 0.43 to 0.70 atmospheres.
|
Example: High altitude Terra
|
Thin Atmosphere (Atmo Type: 5) | World has a pressure of 0.43 to 0.70 atmospheres.
|
Example: High altitude Terra
|
Standard Atmosphere (Atmo Type: 6) | World has a pressure of 0.71 to 1.49 atmospheres.
|
Example: Standard altitude Terra
|
Standard Atmosphere & Tainted Atmosphere (Atmo Type: 7) | World has a pressure of 0.71 to 1.49 atmospheres.
|
Example: Standard altitude Terra
|
Dense Atmosphere (Atmo Type: 8) | World has a pressure of 1.50 to 2.49 atmospheres.
|
Example: Dense, High (D): These worlds have thick N2/O2 atmospheres, but their mean surface pressure is too high to support unprotected human life (high pressure nitrogen and oxygen are deadly to humans). However, pressure naturally decreases with increasing altitude, so if there are highlands at the right altitude the pressure may drop enough to support human life. Alternatively, there may not be any topography high enough for humans to inhabit, necessitating floating gravitic or dirigible habitats or sealed habitats on the surface. [5] |
Dense Atmosphere & Tainted Atmosphere (Atmo Type: 9) | World has a pressure of 1.50 to 2.49 atmospheres.
|
Example: Dense, High (D): These worlds have thick N2/O2 atmospheres, but their mean surface pressure is too high to support unprotected human life (high pressure nitrogen and oxygen are deadly to humans). However, pressure naturally decreases with increasing altitude, so if there are highlands at the right altitude the pressure may drop enough to support human life. Alternatively, there may not be any topography high enough for humans to inhabit, necessitating floating gravitic or dirigible habitats or sealed habitats on the surface. [6] |
Conventional Exotic Atmosphere (Atmo Type: A or 10) | World has a pressure of variable atmospheres.
|
Example: Exotic or Unusual Atmospheres are most noted for widely diverging from the mostly acceptable spectrum of atmospheric temperature, pressure, and gas compositions from the more conventional codes for atmospheres well suited to the major races and conventional life. They typically have atmospheres very divergent from the roughly 80% Nitrogen and 20% Oxygen mixtures of Terran-like life-supporting worlds. |
Corrosive Atmosphere & Conventional Exotic Atmosphere (Atmo Type: B or 11) | World has a pressure of variable atmospheres.
|
Example: Corrosive (B): Corrosive atmospheres are highly dangerous. A sophont who breathes in a corrosive atmosphere will suffer damage every few minutes until death occurs. [7] |
Insidious Atmosphere & Conventional Exotic Atmosphere (Atmo Type: C or 12) | World has a pressure of variable atmospheres.
|
Example: Insidious (C): An insidious atmosphere is like a corrosive one, but it is so corrosive that it attacks equipment as well. The chief danger in an insidious atmosphere is that the toxic gases will destroy the seals and filters on a traveller’s protective gear. An insidious atmosphere worms its way past protection after just a few hours on average, although vigilant maintenance or advanced protective gear can prolong survival times. [8] |
Dense Atmosphere & High Pressure Atmosphere & Unusual Exotic Atmosphere (Atmo Type: D or 13) | World has a pressure of 2.5 or greater atmospheres.
|
Example: High Pressure Atmospheres are classified as possessing 2.5 standard atmospheres or more of pressure. |
Ellipsoid Atmosphere & Unusual Exotic Atmosphere (Atmo Type: E or 14) | World has a pressure of 0.5 or less atmospheres.
|
Example: Ellipsoid Atmospheres are known for having extremely uneven applications of atmosphere, air pressure, and environmental characteristics. This can lead to extremely variable environments and species that can dwell in one environment, but not in a neighboring one only a short distance away. The differences between niche species strongly tend to be more pronounced on an ellipsoidal world. |
Thin Atmosphere & Low Pressure Atmosphere & Unusual Exotic Atmosphere (Atmo Type: F or 15) | World has a pressure of variable atmospheres.
|
Example: One of the advantages of living on a low pressure or vacuum world is easier access to space. Planetary spaceports on low pressure worlds can often provide construction shipyards at a drastically reduced cost, often competitive with orbital shipyards. |
