Bases: Constituent

A constituent which implements the MT-CKD continuum absorption model (AER-RC/MT_CKD).

This constituent requires that the atmosphere contains H2O, CO2, and O3 constituents, each with a vmr property. Pressure, temperature, and wavelengths (or wavenumbers) must also be included so they can be passed to the continuum model.

Derivatives of the continuum absorption with respect to pressure, temperature, H2O, CO2, and O3 are calculated numerically by running the continuum model with perturbed species profiles. This results two additionaly calls to the continuum model for each species when using the default central difference method, or one additional call if a forward difference method is used.

Parameters:

h2o_name (str, optional) – The name of the H2O constituent in the atmosphere. By default “H2O”
co2_name (str, optional) – The name of the CO2 constituent in the atmosphere. By default “CO2”
o3_name (str, optional) – The name of the O3 constituent in the atmosphere. By default “O3”
numeric_wf_fractional_change (float, optional) – The perturbation to use in numeric differentiation of the continuum absorption. By default 1e-2
numeric_wf_central_difference (bool, optional) – If True, use central difference for weighting functions. If False, use forward difference. By default True
