The Atmosphere code is a UWP code to represent the breathing environment encountered on the world. It represents the mixture of gases and other elements that may be present on a world or moon.
Description
Some atmospheres require specific personal equipment for survival and protection.
World Atmosphere Classification Codes Table
Atmospheric Code Descriptions Code Specific Description General Description Pressure (ATM) Remarks 0 Vacuum Vacuum < 0.001 Vacuum requires a vacc suit. The atmosphere has a pressure of less than 0.001 atmospheres, which requires the use of a vacc suit. 1 (Trace) Vacuum 0.001-0.09 The atmosphere has a pressure of less than 0.1 atmospheres, which requires the use of a vacc suit. 2 (Very thin / tainted) Vacuum 0.10-0.42 Very thin tainted requires a filter respirator combination 3 (Very thin) Vacuum 0.10-0.42 Very thin requires a respirator. The atmosphere has a pressure of 0.1 to 0.42 atmospheres, which requires the use of a respirator to ensure sufficient oxygen. 4 (Thin / Tainted) Thin 0.43-0.70 Tainted requires a filter mask. The 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. 5 Thin Thin 0.43-0.70 The atmosphere has a pressure of 0 43 to 0.70 atmospheres. The atmosphere is a standard oxygen/nitrogen mix, which is breathable without assistance. 6 Standard Standard 0.71-1.49 The atmosphere has a pressure of 0.71 to 1.49 atmospheres. The atmosphere is a standard oxygen/nitrogen mix, which is breathable without assistance. 7 (Standard / Tainted) Standard 0.71-1.49 Tainted requires a filter mask. 8 Dense Dense 1.50-2.49 The atmosphere has a pressure of 1.50 to 2.49 atmospheres The atmosphere is a standard oxygen/nitrogen mix, which is breathable without assistance. 9 (Dense / Tainted) Dense 1.50-2.49 Tainted requires a filter mask. A (10) Exotic Exotic varies An unusual gas mix which requires the use of oxygen tanks, but protective suits are not needed. B (11) (Corrosive) Exotic varies A concentrated gas mix or unusual temperature creates a corrosive environment, which requires the use of a Hostile environment suit or vacc suit. C (12) (Insidious) Exotic varies The atmosphere is similar to a corrosive atmosphere, but extreme conditions cause the corrosive effects to defeat any protective measures in 2 to 12 hours. D (13) (Dense, high) Exotic varies Pressure at or below sea level is too great to support life but is breathable at higher altitudes. E (14) † (Ellipsoid) † Exotic varies 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. F (15) † (Thin, low) † Exotic varies The world is large and massive, with a thin atmosphere which settles to the lowest levels of the terrain. The atmosphere is unbreathable at most altitudes except the very low ones (as in depressions or deep valleys).
† - NOTE: In MgT and T5, Atm type E is "Thin, Low", and Atm type F is "Unusual", which includes (but is not limited to) Ellipsoidal atmospheres.
