carbon_cycle_mod.F90 @ 3473

Last change on this file since 3473 was 3459, checked in by oboucher, 6 years ago
Changing hard-coded value of 28.97 g/mol by RMD physical constant defined in suphel.F90 As rmd = 28.9644, this involves a lack of numerical convergence with previous commit.

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

6	! Purpose and description:
7	! -----------------------
8	! Control module for the carbon CO2 tracers :
9	! - Identification
10	! - Get concentrations comming from coupled model or read from file to tracers
11	! - Calculate new RCO2 for radiation scheme
12	! - Calculate new carbon flux for sending to coupled models (PISCES and ORCHIDEE)
13	!
14	! Module permettant de mettre a jour les champs (puits et sources) pour le
15	! transport de CO2 en online (IPSL-CM et LMDZOR) et offline (lecture de carte)
16	!
17	! Le cas online/offline est defini par le flag carbon_cycle_cpl (y/n)
18	! Le transport du traceur CO2 est defini par le flag carbon_cycle_tr (y/n)
19	! la provenance des champs (termes de puits) est denini par le flag level_coupling_esm
20	!
21	! level_coupling_esm : level of coupling of the biogeochemical fields between
22	! LMDZ, ORCHIDEE and NEMO
23	! Definitions of level_coupling_esm in physiq.def
24	! level_coupling_esm = 0 ! No field exchange between LMDZ and ORCHIDEE models
25	! ! No field exchange between LMDZ and NEMO
26	! level_coupling_esm = 1 ! Field exchange between LMDZ and ORCHIDEE models
27	! ! No field exchange between LMDZ and NEMO models
28	! level_coupling_esm = 2 ! No field exchange between LMDZ and ORCHIDEE models
29	! ! Field exchange between LMDZ and NEMO models
30	! level_coupling_esm = 3 ! Field exchange between LMDZ and ORCHIDEE models
31	! ! Field exchange between LMDZ and NEMO models

609	! Purpose and description:
610	! -----------------------
611	!
612	! Infofields
613	! this routine enables to define the field exchanges in both directions between
614	! the atmospheric circulation model (LMDZ) and ORCHIDEE. In the future this
615	! routing might apply to other models (e.g., NEMO, INCA, ...).
616	! Therefore, currently with this routine, it is possible to define the coupling
617	! fields only between LMDZ and ORCHIDEE.
618	! The coupling_fields.def file enables to define the name of the exchanged
619	! fields at the coupling interface.
620	! field_in_names : the set of names of the exchanged fields in input to ORCHIDEE
621	! (LMDZ to ORCHIDEE)
622	! field_out_names : the set of names of the exchanged fields in output of
623	! ORCHIDEE (ORCHIDEE to LMDZ)
624	! n : the number of exchanged fields at th coupling interface
625	! nb_fields_in : number of inputs fields to ORCHIDEE (LMDZ to ORCHIDEE)
626	! nb_fields_out : number of ouput fields of ORCHIDEE (ORCHIDEE to LMDZ)
627	!
628	! The syntax for coupling_fields.def is as follows:
629	! IMPORTANT: each column entry must be separated from the previous one by 3
630	! spaces and only that
631	! field name coupling model 1 model 2 long_name
632	! direction
633	! 10char -3spaces- 3char -3spaces- 4char -3spaces- 4char -3spaces- 30char
634	!
635	! n
636	! FIELD1 IN LMDZ ORC
637	! ....
638	! FIELD(j) IN LMDZ ORC
639	! FIELD(j+1) OUT LMDZ ORC
640	! ...
