Method Details

pressureAtAltitude

public static Quantity<Pressure> pressureAtAltitude(Quantity<Length> altitude)

Barometric formula for pressure at altitude. P = P0 * (1 - L*h/T0)^(g*M/(R*L))

Parameters:

altitude - Height above sea level

Returns:

Pressure at altitude

altitudeFromPressure

public static Quantity<Length> altitudeFromPressure(Quantity<Pressure> pressure)

Calculates altitude from pressure (inverse barometric).

temperatureAtAltitude

public static double temperatureAtAltitude(double altitudeMeters)

Temperature at altitude (troposphere). T = T0 - L * h
