pressure_to_altitude_stratosphere

rojak.core.calculations.pressure_to_altitude_stratosphere(pressure: NumpyOrDataArray) → NumpyOrDataArray

Convert pressure to altitude for the stratosphere

Please use pressure_to_altitude_icao() for pressures in both the troposphere and stratosphere.

An implementation of equation 41 from ICAO manual [NACA3182]

\[\text{H} = \text{H}^* + \frac{1}{\text{B}} \left[ n \log_{10} \left( \frac{T^*}{T_0} \right) \right] - \frac{1}{\text{B}} \log_{10} \left( \frac{P}{P_0} \right)\]

where \(^*\) indicates values at the tropopause, \(H\) is the geopotential height and is treated as equivalent to altitude for engineering purposes (see [NACA3182] for details).

Parameters:

pressure (NumpyOrDataArray) – Pressure in hPa

Return type:

NumpyOrDataArray

Returns:
