class exo_k.atm_evolution.tracers.Tracers(settings, tracers=None, tracer_values=None, Kzz=0.0, Dmol=0.0, bg_vmr=None, M_bg=None, Nlay=None, **kwargs)[source]

Bases: object

Class that deals with tracers.

Fills out the tracers.qarray and creates tracer_names, a table of correspondence between tracer names and indices in tracers.qarray.

update_gas_composition(update_vmr=True)[source]

Performs mass to volume mixing ratio conversion, computes the new molar mass of the total gas and transmits new composition to the radiative model.

!!!Small discrepancies with case without tracers!!! Maybe a problem with the background gas. JL22 => is this still true ?

Parameters:

atm (exo_k.Atm object) – If atm is provided, its composition will be updated with the new composition.

update_aerosol_properties(atm)[source]
turbulent_diffusion(timestep, Htot, atm, cp)[source]

Mixes tracers following a diffusion equation with a constant Kzz parameter (self.Kzz in m^2/s).

Parameters:

  • timestep (float) – physical timestep of the current step (in s/cp). (needs to be converted before it is sent to turbulent diffusion)

  • Htot (array, np.ndarray) – Total heating rate (in W/kg) of all physical processes already computed

  • atm (Atm object) – The Atm object used in the radiative transfer which contains many state variables.

dry_convective_adjustment(timestep, Htot, atm, verbose=False)[source]

Computes convective adjustement.

Parameters:

  • timestep (float) – physical timestep of the current step (in s/cp). (needs to be converted before it is sent to `turbulent diffusion)

  • Htot (array, np.ndarray) – Total heating rate (in W/kg) of all physical processes already computed

  • atm (Atm object) – The Atm object used in the radiative transfer which contains many state variables.

update_surface_reservoir(condensing_pairs_idx=False, surf_layer_mass=0.0)[source]

Update surface reservoirs of tracers.

E.g. deals with removing excess condensates from the first layer or putting more when everything as been evaporated.
