Atmosphere

Atmosphere Classifications -> Summary Synopsis Paragraphs

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: At altitudes above 4,000 meters on Terra, such as most of the Tibetan plateau, the oxygen content in every breath full drops almost to 50%, whilst above 7,000 meters (the peaks of the Himalaya mountains) the lack of available oxygen reaches lethal levels. This extreme altitude on the 'roof of the world' is equivalent to the IISS Scout Code atmosphere of Very Thin. For most explorers, respirators or oxygen masks will be required in this type of environment. [1]
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: At altitudes above 4,000 meters on Terra, such as most of the Tibetan plateau, the oxygen content in every breath full drops almost to 50%, whilst above 7,000 meters (the peaks of the Himalaya mountains) the lack of available oxygen reaches lethal levels. This extreme altitude on the 'roof of the world' is equivalent to the IISS Scout Code atmosphere of Very Thin. For most explorers, respirators or oxygen masks will be required in this type of environment. [2]
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: At altitudes above 2,500 meters on Terra, the air pressure drops to around 0.70 that of sea level. This is equivalent to the IISS Scout Code atmosphere type of Thin. Sophonts who are not adapted to such conditions can suffer from altitude sickness, with headaches, nausea, extreme tiredness, breathlessness and body pain. Associated high blood pressure can cause complications for pregnant women. [3]
Thin Atmosphere World has a pressure of 0.43 to 0.70 atmospheres.
  • No survival gear required.
 Example: At altitudes above 2,500 meters on Terra, the air pressure drops to around 0.70 that of sea level. This is equivalent to the IISS Scout Code atmosphere type of Thin. Sophonts who are not adapted to such conditions can suffer from altitude sickness, with headaches, nausea, extreme tiredness, breathlessness and body pain. Associated high blood pressure can cause complications for pregnant women. [4]
Standard Atmosphere World has a pressure of 0.71 to 1.49 atmospheres.
  • No survival gear required.
 Example: On Earth, sophonts have little experience of differing atmospheric pressures, and so many underestimate how much of an impact this factor may have on everyday life. Terran inhabitants are actually living near the bottom of an ocean of air. At sea level, the weight of the air presses down on its inhabitants with a pressure of 1.0 kg per squared centimeter. At higher altitudes, less air means less weight and less pressure. The pressure and density of air decreases with increasing elevation.
Standard Atmosphere & Tainted Atmosphere World has a pressure of 0.71 to 1.49 atmospheres.

Terran inhabitants are actually living near the bottom of an ocean of air. At sea level, the weight of the air presses down on its inhabitants with a pressure of 1.0 kg per squared centimeter. At higher altitudes, less air means less weight and less pressure. The pressure and density of air decreases with increasing elevation.
Dense Atmosphere World has a pressure of 1.50 to 2.49 atmospheres.
  • No survival gear required.
 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]

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 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 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 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.
