Atmosphere Codes (AC) Classifications -> Summary Synopsis Paragraphs
Atmo Code Statement (Summary Synopsis Paragraph) Remarks
Vacuum Atmosphere World has a pressure of less than 0.001 atmospheres, which requires the use of a vacc suit.
  • Vacuum requires a vacc suit.
  • TL-8 or more advanced survival gear is required to settle this world.
 Example: Terran Moon
Trace Atmosphere World has a pressure of less than 0.1 atmospheres, which requires the use of a vacc suit.
  • Trace requires a vacc suit.
  • TL-8 or more advanced survival gear is required to settle this world.
 Example: Mercury (world)
Very Thin Atmosphere & Tainted Atmosphere World has a pressure of 0.10 to 0.42 atmospheres. Example: TBD
Very Thin Atmosphere World has a pressure of 0.10 to 0.42 atmospheres.
  • This atmosphere requires a respirator.
  • TL-5 or more advanced survival gear is required to settle this world.
 Example: TBD
Thin Atmosphere & Tainted Atmosphere World has a pressure of 0.43 to 0.70 atmospheres.
  • It also has a Tainted Atmosphere which is a type of atmosphere known for possessing irritants that make it difficult or impossible for conventional sophonts to tolerate respiration for any length of time.
  • This atmosphere contains an unusual taint such as such as disease, a hazardous gas mix, pollutants, or sulfur compounds which requires the use of a filter mask.
  • TL-3 or more advanced survival gear is required to settle this world.
 Example: TBD
Thin Atmosphere World has a pressure of 0.43 to 0.70 atmospheres.
  • No survival gear required.
 Example: TBD
Standard Atmosphere World has a pressure of 0.71 to 1.49 atmospheres.
  • No survival gear required.
 Example: TBD
Standard Atmosphere & Tainted Atmosphere World has a pressure of 0.71 to 1.49 atmospheres. Example: TBD
Dense Atmosphere World has a pressure of 1.50 to 2.49 atmospheres.
  • No survival gear required.
 Example: TBD
Dense Atmosphere & Tainted Atmosphere World has a pressure of 1.50 to 2.49 atmospheres. Example: TBD
Conventional Exotic Atmosphere World has a pressure of variable atmospheres. Example: TBD
Corrosive Atmosphere & Conventional Exotic Atmosphere World has a pressure of variable atmospheres. Example: TBD
Insidious Atmosphere & Conventional Exotic Atmosphere World has a pressure of variable atmospheres. Example: TBD
Dense Atmosphere & High Pressure Atmosphere & Unusual Exotic Atmosphere World has a pressure of 2.5 or greater atmospheres.
  • Typically no survival gear is required under many conditions.
  • Pressure at or below sea level is too great to support life but is breathable at higher altitudes.
  • TL-5 or more advanced survival gear is required to settle this world.
 Example: TBD
Ellipsoid Atmosphere & Unusual Exotic Atmosphere World has a pressure of 0.5 or less atmospheres.
  • Typically no survival gear is required under many conditions.
  • The world’s surface is ellipsoidal, not spherical. Because the atmosphere remains spherical, surface atmospheric pressure ranges from very high at the middle to very low at the ends.
  • Breathable bands may exist at some point within the range of pressure.
  • TL-5 or more advanced survival gear is required to settle this world.
 Example: TBD
Thin Atmosphere & Low Pressure Atmosphere & Unusual Exotic Atmosphere World has a pressure of variable atmospheres.
  • Typically no survival gear is required under some conditions.
  • This world is large and massive, with a thin atmosphere which settles to the lowest levels of the terrain.
  • The atmosphere is un-breathable at most altitudes except the very low ones (…as in depressions or deep valleys).
  • TL-8 or more advanced survival gear is required to settle this world.
 Example: TBD
