carbon_cycle_mod.F90 @ 3391

Last change on this file since 3391 was 3391, checked in by oboucher, 6 years ago
Fields can now be passed to ORCHIDEE through surf_land_orchidee. Fields are compressed in pbl_surface_mod and uncompressed in surf_land_orchidee. Cosmetic changes, including in surf_land_mod.

	6	! Purpose and description:
	7	! -----------------------
	8	! Control module for the carbon CO2 tracers :
[1454]	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	!
[3387]	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

	597	!
	598	! Infofields
	599	! this routine enables to define the field exchanges in both directions between
	600	! the atmospheric circulation model (LMDZ) and ORCHIDEE. In the future this
	601	! routing might apply to other models (e.g., NEMO, INCA, ...).
	602	! Therefore, currently with this routine, it is possible to define the coupling
	603	! fields only between LMDZ and ORCHIDEE.
	604	! The coupling_fields.def file enables to define the name of the exchanged
	605	! fields at the coupling interface.
	606	! field_in_names : the set of names of the exchanged fields in input to ORCHIDEE
	607	! (LMDZ to ORCHIDEE)
	608	! field_out_names : the set of names of the exchanged fields in output of
	609	! ORCHIDEE (ORCHIDEE to LMDZ)
	610	! n : the number of exchanged fields at th coupling interface
	611	! nb_fields_in : number of inputs fields to ORCHIDEE (LMDZ to ORCHIDEE)
	612	! nb_fields_out : number of ouput fields of ORCHIDEE (ORCHIDEE to LMDZ)
	613	!
	614	! The syntax for coupling_fields.def is as follows:
	615	! IMPORTANT: each column entry must be separated from the previous one by 3
	616	! spaces and only that
	617	! field name coupling model 1 model 2 long_name
	618	! direction
