ProfileExtrapolation.standard_water_vapour_pressure(h: ndarray, h_0: Optional[float] = 2.0, rho_0: Optional[float] = 7.5) → ndarray#

Determine the standard water vapour pressure at a given height.

The reference standard atmosphere is based on the United States Standard Atmosphere, 1976, in which the atmosphere is divided into seven successive layers showing linear variation with temperature.

Parameters:

  • h (numpy.ndarray) – Height (km)

  • h_0 (float) – Scale height (km) Default 2.

  • rho_0 (float) – Surface water vapour density (g/m^3) Default 7.5

Returns:

e – Water vapour pressure (hPa)

Return type:

numpy.ndarray
