pyrtlib.climatology.AtmosphericProfiles.gl_atm#

static AtmosphericProfiles.gl_atm(atm: int) → Tuple[ndarray, ndarray, ndarray, ndarray, ndarray]#

Returns the Atmopshere profile.

This method contains 6 model profiles:

option	model
1	Tropical
2	Midlatitude Summer
3	Midlatitude Winter
4	Subarctic Summer
5	Subarctic Winter
6	U.S. Standard

Parameters:

option (int) – the atmosphere profile.

Returns:

a (numpy.ndarray): Altitudes (km) (50x1)
p (numpy.ndarray): Pressure (mbar)
d (numpy.ndarray): Total density (cm-3)
t (numpy.ndarray): Temperature (K)
md (numpy.ndarray): Molecular densities (ppmv)

Return type:

Tuple[numpy.ndarray, numpy.ndarray, numpy.ndarray, numpy.ndarray, numpy.ndarray]
