absorption_coefficient(temperature, pressure, volume_mixing_ratio, grid, remove_pedestal=False, cut_off=25)[source]

Calculates absorption coefficient.

Parameters:

  • temperature – Temperature [K].

  • pressure – Pressure [Pa].

  • volume_mixing_ratio – Volume mixing ratio [mol mol-1].

  • grid – Numpy array defining the spectral grid [cm-1].

  • remove_pedestal – Flag specifying if a pedestal should be subtracted.

  • cut_off – Wavenumber cut-off distance [cm-1] from line centers.

Returns:

Numpy array of absorption coefficients [m2].

pyLBL.c_lib.gas_optics.check_return_code(value)[source]

Checks or errors occurring in the c routines.

Parameters:

value – Integer return code.

Raises:

ValueError if an error is encountered. –
