altitude_in_ft_to_pressure#

rojak.core.calculations.altitude_in_ft_to_pressure(altitude)[source]#

Convert altitude in ft to pressure in hPa for ICAO standard atmosphere [NACA3182]

The altitude is converted to m and passed to altitude_to_pressure_icao(). Dask-backed inputs (i.e. dask.array.Array, dask-backed xarray.DataArray, dask.dataframe.Series and dask.dataframe.DataFrame) remain lazy.

Parameters:

altitude (T) – Altitude in ft. For a dataframe, every column is converted.

Returns:

Pressure in hPa, of the same type and shape as altitude. The index and name (or columns) of pandas/dask dataframe objects, and the coordinates, attributes and name of a xarray.DataArray are retained.

Return type:

T

Examples

>>> ddf["pressure_level"] = altitude_in_ft_to_pressure(ddf["altitude"])
