pytmosph3r.opacity

Module Contents

class Opacity(rayleigh: bool = False, cia: List[str] | None = None, wn_range: Tuple[float, float] | None = None, k_data=None, doppler=None)[source]

Bases: pytmosph3r.log.Logger, exo_k.util.spectral_object.Spectral_object

This module is the (main) link between pytmosph3r and exo_k. It will load the gas databases (load_gas_database()), and compute the opacities (compute()) of a list of cells of the atmosphere (using their physical properties: P, T, etc).

The parameters of the Opacity module are:

Parameters:

  • rayleigh (bool, optional) – Activates Rayleigh. Defaults to None.

  • cia (list, optional) – List of molecules for which to compute Collision Induced Absorption. Defaults to None. Example: ['H2','He'].

  • wn_range (tuple, optional) – Range (wn_min, wn_max) of wave numbers to select for the computations. Defaults to None.

  • k_data (exo_k.Kdatabase, optional) – Exo_k object containing the gas database (especially useful if you will run multiple models, with the same data). Defaults to None.

  • cia_data (exo_k.Kdatabase, optional) – Exo_k object containing the CIA database (especially useful if you will run multiple models, with the same data). Defaults to None.

property wns
property wnedges
rayleigh

Activate Rayleigh (by default, it is deactivated).

doppler

Activate Doppler (by default, it is deactivated). Dictionary containing ‘Kp’ and ‘phi’ values. TODO

cia

List of molecules to look for when computing CIA pairs.

classmethod fromQuantity(rayleigh: bool = False, cia: List | None = None, w_range: List | None = None)[source]

Create an Opacity object using astropy quantity for wn_range.

Parameters:

  • rayleigh (bool) –

  • cia (List[str]) –

  • w_range (List[Quantity]) – Range of quantity to determine (wn_min, wn_max) ie wn_range

Returns:

Opacity

load_gas_database(model)[source]

Loading exo_k gas/CIA/aerosols databases, and potentially clip the spectral range.

compute(log_p, temperature, gas_vmr, aer_reff_densities, winds, coords, wn_range)[source]

Compute the opacities for a list of cells of the atmosphere.

Parameters:

  • log_p (ndarray) – Log10(pressure) of each cell

  • temperature (ndarray) – Temperature of each cell

  • gas_vmr (ndarray) – gas dictionary ({gas_name: VMR}) of each cell

  • aer_reff_densities (ndarray) – Aerosol data of each cell (see PrepareAerosols)

  • winds (ndarray) – Winds (u,v,w) of each cell

  • coords (ndarray) – Coordinates (z,lat,lon) of each cell

  • wn_range (ndarray) – Wavenumber range to consider
