The Standard Atmosphere is a unit of pressure.
- It is a kind of Metric used in Planetology.
- It is a measure of the atmosphere of a world.
- Atmospheric pressure may also be measured in bars and millibars.
Description (Specifications)[edit]
The descriptions of Atmospheres are given in the relative terms of Standard Atmospheres, rather than the absolute units, as a method of making comparisons to the human physiological norm easier.
One Atmosphere is defined as being precisely equal to 101.325 kPa (kilopascals). The pascal is a unit of force used to quantify pressure and is defined as one newton per square meter.
- The Atmosphere is based on the mean surface atmospheric pressure of Terra.
- The standard abbreviation is atm.
Atmosphere Types[edit]
Within Charted Space, the atmospheres of worlds are rated according to a standard scale, based on their mean surface pressure.
- Atmosphere code 0: Vacuum Pressure Atmosphere (less than 0.001 atm)
- Atmosphere code 1: Trace Pressure Atmosphere (less than 0.1 atm)
- Atmosphere codes 2 and 3: Very Thin Pressure Atmosphere (between 0.1 and 0.42 atm)
- Atmosphere codes 4 and 5: Thin Pressure Atmosphere (between 0.42 and 0.7 atm)
- Atmosphere codes 6 and 7: Standard Pressure Atmosphere (between 0.7 and 1.5 atm)
- Atmosphere codes 8 and 9: Dense Pressure Atmosphere (between 1.5 and 2.5 atm)
- Typically Atmosphere code A+: Very Dense Pressure Atmosphere (above 2.5 atm)
- Typically Atmosphere code B+: Extreme Pressure Atmosphere (above 100 atm)
History & Background (Dossier)[edit]
The Atmosphere was first defined as a unit of pressure on Terra prior to the foundation of the Terran Confederation. It is defined as the mean surface pressure of Terra's atmosphere. The true atmospheric pressure of a world can vary, even on Terra: the local atmospheric pressure can vary from the standard by as much as 15%, affected by weather, temperature, tides, and altitude. Technologists found the Atmosphere useful as the concept of the Technology Level and standardized ideas about sophont society development began to take form.[1]
