}| Property | Format | Description |
|---|---|---|
| enabled | Boolean | Whether the body has an atmosphere. |
| oxygen | Boolean | Whether the atmosphere contains oxygen. Used for whether jet engines should work in the atmosphere. |
| ambientColor | Color | All objects inside of the atmosphere will slightly shine in this color. |
| lightColor | Color | (Deprecated) Sets the AFG waveLength to this value. If AFG is not included, it automatically creates a new AFG. |
| staticDensityASL | Decimal | Atmospheric density at sea level. Used to calculate the parameters of the atmosphere if no curves are used. |
| staticPressureASL | Decimal | The static pressure at sea level in kPa. Used to calculate the parameters of the atmosphere if no curves are used. It is displayed in KSP under the body information. |
| temperatureSeaLevel | Decimal | The static temperature in Kelvin at sea level. Used to calculate the parameters of the atmosphere if no curves are used. |
| adiabaticIndex | Decimal | The ratio of the heat capacity of a gas at constant pressure to its heat capacity at constant volume. Used to determine the speed of sound. |
| atmosphereDepth | Decimal | (Also altitude,maxAltitude) The atmosphere cutoff altitude/height of the atmosphere. |
| gasMassLapseRate | Decimal | ? |
| atmosphereMolarMass | Decimal | The average molar mass of all the gases in the atmosphere in kg/mol. Used to determine density (which is then also a factor in the speed of sound.) |
| temperatureLapseRate | Decimal | ? |
| pressureCurveIsNormalized | Boolean | Whether the pressure curve height values should use absolute (0 - atmosphereDepth) or relative (0 - 1) values. |
| pressureCurve | FloatCurve | Assigns a pressure value (in kPa) to a height value inside of the atmosphere. |
| temperatureCurveIsNormalized | Boolean | Whether the temperature curve should use absolute (0 - atmosphereDepth) or relative (0 - 1) values. |
| temperatureCurve | FloatCurve | Assigns a temperature value (in Kelvin) to a height value inside of the atmosphere. |
| temperatureSunMultCurve | FloatCurve | This curve takes altitude (meters) and returns a multiplier. Its value defines how temperatureSeaLevel varies with altitude. |
| temperatureLatitudeBiasCurve | FloatCurve | This curve takes latitude (degrees) and returns temperature (K). Its value defines the latitudinal temperature variation. |
| temperatureLatitudeSunMultCurve | FloatCurve | This curve takes latitude (degrees) and returns temperature (K). Its value defines the diurnal temperature variation. |
| temperatureAxialSunBiasCurve | FloatCurve | This curve takes true anomaly (degrees) and returns temperature (K). Its value defines the seasonal temperature variation. |
| temperatureEccentricityBiasCurve | FloatCurve | This curve takes a value between 0 (periapsis) and 1 (apoapsis) and returns temperature (K). Its value defines the temperature variation due to orbital eccentricity. |
