################################# Parameters for various processes ################################# .. role:: bash(code) :language: bash CHIMERE takes into account various processes: deep convection, emissions, transport and mixing, chemistry, etc. A number of choices are available to the user. See :doc:`CHIMERE plugin` for information on how these are done in the yaml. ideepconv --------- The choice of how to take deep convection into account: - 0: no deep convection. In this case, the related mass fluxes in :doc:`METEO.nc` are ignored and can therefore be omitted when pre-processing the meteo. - 1: CHIMERE will select deep convection automatically according to the resolution in each column (see :bash:`locvalues`), compute the deep convection fluxes from the mass fluxes provided in METEO.nc and take into account the production and loss due to deep convection (see :bash:`transmix`). XXXX ON A VIRE TIEDKE APPAREMMENT XXXX useemisb -------- A switch to take into account or not :doc:`BEMISSION`. Called optemisb in CHIMERE, if not taken into account, the input file is not read and :bash:`inemisb` remains at 0 for all species(consequently, "Biogenic emissions" are not added up in :bash:`emissions`). usechemistry ------------ A switch to take into account or not the :doc:`chemistry`. Condition for calling routine chemistry in prodloss. useemissions ------------ A switch to take into account or not both types of :doc:`emissions`. Condition for calling routine emissions in prodloss. usetransmix ------------ A switch to take into account or not transport and mixing. Condition for calling routine transmix in prodloss. usewetdepos ------------ A switch to take into account or not wet deposition. Condition for calling routine wdeposition in prodloss. usedepos ------------ A switch to take into account or not dry deposition. Condition for calling routine deposition in prodloss. useabsclipconc -------------- A switch to clip or not small concentrations in absolute value. WARNING: negative concentrations with large absolute values are therefore possible. They are not well treated by the chemistry routine but are required when computing response functions (i.e. cases with no or liner chemistry). See :bash:`twostep_mod`. clipconc -------- The value at which the concentations are clipped (see in :bash:`twostep_mod`), positive.
