Atmosphere¶

A Structure closely tied to Body A variable of type Atmosphere usually is obtained by the :ATM suffix of a Body. ALL The following values are read-only. You can’t change the value of a body’s atmosphere.

structure Atmosphere¶

Suffix	Type	Description
`BODY`	string	Name of the celestial body
`EXISTS`	boolean	True if this body has an atmosphere
`OXYGEN`	boolean	True if oxygen is present
`SCALE`	scalar	Used to find atmospheric density
`SEALEVELPRESSURE`	scalar (atm)	pressure at sea level
`HEIGHT`	scalar (m)	advertised atmospheric height

Atmosphere:BODY¶

Type:	string
Access:	Get only

The Body that this atmosphere is around - as a STRING NAME, not a Body object.

Atmosphere:EXISTS¶

Type:	boolean
Access:	Get only

True if this atmosphere is “real” and not just a dummy placeholder.

Atmosphere:OXYGEN¶

Type:	boolean
Access:	Get only

True if the air has oxygen and could therefore be used by a jet engine’s intake.

Atmosphere:SCALE¶

Type:	scalar
Access:	Get only

A math constant plugged into a formula to find atmosphere density.

Atmosphere:SEALEVELPRESSURE¶

Type:	scalar (atm)
Access:	Get only

Number of Atm’s at planet’s sea level 1.0 Atm’s = same as Kerbin.

Atmosphere:HEIGHT¶

Type:	scalar (m)
Access:	Get only

The altitude at which the atmosphere is “officially” advertised as ending. (actual ending value differs, see below).

Atmospheric Math¶

Note

[Section deleted]

This documentation used to contain a description of how the math for Kerbal Space Program’s default stock atmospheric model works, but everything that was mentioned here became utterly false when KSP 1.0 was released with a brand new atmospheric model that invalided pretty much everything that was said here. Rather than teach people incorrect information, it was deemed that no documentation is better than misleading documentation, so this section below this point has been removed.
