pyrtlib.absorption_model.N2AbsModel.n2_absorption_mwl24#

static N2AbsModel.n2_absorption_mwl24(t: ndarray, p: ndarray, f: ndarray) → ndarray#

Calculation of the collision-induced absorption by N2-N2 molecular pairs Based on the Classic Trajectory Calcs by Vigasin/Chistikov/Finenko

Parameters:

f (np.ndarray) – frequency (Ghz)
p (np.ndarray) – dry air pressure (mbar) (recalculations to Torr are used inside)
t (np.ndarray) – air temperature (K)

Returns:

N2-N2 absorption coefficient in 1/cm

Return type:

np.ndarray

Note

Convert to Np/km by multiplying by 1.E5. Convert to dry air absorption by multiplying by 0.84 (see [Meshkov-DeLucia-2007])
