Method	Description
GetDensity ( UnityEngine.Vector3d position, CelestialBody body ) : double
GetDensity ( double altitude, CelestialBody body ) : double	Gets the air density (rho) for the specified altitude on the specified body. This is an approximation, because actual calculations, taking sun exposure into account to compute air temperature, require to know the actual point on the body where the density is to be computed (knowing the altitude is not enough). However, the difference is small for high altitudes, so it makes very little difference for trajectory prediction.
GetTemperature ( UnityEngine.Vector3d position, CelestialBody body ) : double	This function should return exactly the same value as Vessel.atmDensity, but is more generic because you don't need an actual vessel updated by KSP to get a value at the desired location. Computations are performed for the current body position, which means it's theoritically wrong if you want to know the temperature in the future, but since body rotation is not used (position is given in sun frame), you should get accurate results up to a few weeks.
SimAeroForce ( Vessel _vessel, Vector3 v_wrld_vel, Vector3 position ) : Vector3
SimAeroForce ( Vessel _vessel, Vector3 v_wrld_vel, double altitude, double latitude = 0.0 ) : Vector3

GetDensity() public static method

Gets the air density (rho) for the specified altitude on the specified body. This is an approximation, because actual calculations, taking sun exposure into account to compute air temperature, require to know the actual point on the body where the density is to be computed (knowing the altitude is not enough). However, the difference is small for high altitudes, so it makes very little difference for trajectory prediction.

public static GetDensity ( double altitude, CelestialBody body ) : double
altitude	double	Altitude above sea level (in meters)
body	CelestialBody
return	double

GetTemperature() public static method

This function should return exactly the same value as Vessel.atmDensity, but is more generic because you don't need an actual vessel updated by KSP to get a value at the desired location. Computations are performed for the current body position, which means it's theoritically wrong if you want to know the temperature in the future, but since body rotation is not used (position is given in sun frame), you should get accurate results up to a few weeks.
