MODULE carbon_cycle_mod
!=======================================================================
!   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

!  Purpose and description:
!  -----------------------

! 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
!                    direction
!   10char  -3spaces-  3char  -3spaces- 4char -3spaces- 4char -3spaces-  30char 

! n
! FIELD1 IN LMDZ ORC
! ....
! FIELD(j) IN LMDZ ORC
! FIELD(j+1) OUT LMDZ ORC
