ProfileExtrapolation.pressure(lat: float, h: ndarray, season: Optional[str] = 'summer') → ndarray#

Determine the atmospheric pressure at a given latitude and height.

Method to determine the pressure as a function of altitude and latitude, for calculating gaseous attenuation along an Earth-space path. This method is recommended when more reliable local data are not available.

Parameters:

  • lat (numpy.ndarray) – Latitude (degree)

  • h (numpy.ndarray) – Height (km)

  • season (str) – Season of the year (available values, ‘summer’, and ‘winter’). Default ‘summer’

Returns:

P – Pressure (hPa)

Return type:

numpy.ndarray
