emc2.simulator.attenuation.calc_theory_beta_m¶
- emc2.simulator.attenuation.calc_theory_beta_m(model, Lambda, OD_from_sfc=True)[source]¶
This calculates the molecular scattering parameters for a given model. In particular, the two-way transmittance, optical depth, volume extinction/backscatter cross sections, Rayleigh scattering cross sections, number density profile and refreactive index will be calculated.
- Parameters:
- model: Model
The model to calculate the parameters for.
- Lambda: float
The wavelength (in microns).
- OD_from_sfc: bool
If True, optical depth will be calculated from the surface. If false, optical depth will be calculated from the top of the atmosphere.
- Returns:
- model: Model
The model with the molecular scattering parameters added.
