  !   Authors: Patricia Cadule and Laurent Fairhead
  !            base sur un travail anterieur mene par Patricia Cadule et Josefine Ghattas

  !  Purpose and description:
  !  -----------------------
  ! Control module for the carbon CO2 tracers :
  !   - Initialisation of carbon cycle fields
  !   - Definition of fluxes to be exchanged

  ! Rest of code is in tracco2i.F90

  ! Le cas online/offline est defini par le flag carbon_cycle_cpl (y/n)
  ! Le transport du traceur CO2 est defini par le flag carbon_cycle_tr (y/n)
  ! la provenance des champs (termes de puits) est denini par le flag level_coupling_esm

  ! level_coupling_esm : level of coupling of the biogeochemical fields between
  ! LMDZ, ORCHIDEE and NEMO
  ! Definitions of level_coupling_esm in physiq.def
  ! level_coupling_esm = 0  ! No field exchange between LMDZ and ORCHIDEE models
  !                         ! No field exchange between LMDZ and NEMO
  ! level_coupling_esm = 1  ! Field exchange between LMDZ and ORCHIDEE models
  !                         ! No field exchange between LMDZ and NEMO models
  ! level_coupling_esm = 2  ! No field exchange between LMDZ and ORCHIDEE models
  !                         ! Field exchange between LMDZ and NEMO models
  ! level_coupling_esm = 3  ! Field exchange between LMDZ and ORCHIDEE models
  !                         ! Field exchange between LMDZ and NEMO models

    !  -----------------------

    ! Infofields
    ! this routine enables to define the field exchanges in both directions between
    ! the atmospheric circulation model (LMDZ) and ORCHIDEE. In the future this
    ! routing might apply to other models (e.g., NEMO, INCA, ...).
    ! Therefore, currently with this routine, it is possible to define the coupling
    ! fields only between LMDZ and ORCHIDEE.
    ! The coupling_fields.def file enables to define the name of the exchanged
    ! fields at the coupling interface.
    ! field_in_names : the set of names of the exchanged fields in input to ORCHIDEE
    ! (LMDZ to ORCHIDEE)
    ! field_out_names : the set of names of the exchanged fields in output of
    ! ORCHIDEE (ORCHIDEE to LMDZ)
    ! n : the number of exchanged fields at th coupling interface
    ! nb_fields_in : number of inputs fields to ORCHIDEE (LMDZ to ORCHIDEE)
    ! nb_fields_out : number of ouput fields of ORCHIDEE (ORCHIDEE to LMDZ)

    ! The syntax for coupling_fields.def is as follows:
    ! IMPORTANT: each column entry must be separated from the previous one by 3
    ! spaces and only that
    ! field name         coupling          model 1         model 2         long_name
