MODULE CARBON_MOD

!******************************************************************************
! Module CARBON_MOD contains arrays and routines for performing a
! carbonaceous aerosol simulation. Original code taken from Mian Chin's
! GOCART model and modified accordingly. (rjp, bmy, 4/2/04, 2/19/09)
!
! 4 Aerosol species : Organic and Black carbon
! : hydrophilic (soluble) and hydrophobic of each
! For secondary organic aerosol (SOA) simulation orginal code developed
! by Chung and Seinfeld [2002] and Hong Liao from John Seinfeld's group
! at Caltech was taken and further modified accordingly (rjp, bmy, 7/15/04)
! This simulation introduces additional following species:
! ALPH, LIMO, ALCO, SOA1, SOA2, SOA3, SOA4, SOG1, SOG2, SOG3, SOG4

! (2 ) Now references "directory_mod.f", "logical_mod.f", "tracer_mod.f".
! (bmy, 7/20/04)
! (3 ) Now read data from carbon_200411/ subdir of DATA_DIR. Also added
! some extra debug output. Now read T. Bond yearly emissions as
! default, but overwrite N. America with the monthly Cooke/RJP
! emissions. Added module variables I1_NA, I2_NA, J1_NA, J2_NA.
! (rjp, bmy, 12/1/04)
! (4 ) Now can read seasonal or interannual BCPO, OCPO biomass emissions.
! Also parallelize loop in OHNO3TIME. (rjp, bmy, 1/18/05)
! (5 ) Now references "pbl_mix_mod.f". Bug fix: now make sure only to save
! up to LD07 levels for the ND07 diagnostic in SOA_LUMP. (bmy, 3/4/05)
! (6 ) Now can read data for both GEOS and GCAP grids (bmy, 8/16/05)

! (9 ) Bug fix for GCAP in BIOGENIC_OC (bmy, 4/11/06)
! (10) Updated for SOA production from ISOP (dkh, bmy, 5/22/06)
! (11) Updated for IPCC future emission scale factors. Also added function
! GET_DOH to return ISOP that has reacted w/ OH. (swu, dkh, bmy, 6/1/06)

! (13) Minor fix for 20 carbon tracers. (phs, 9/14/06)
! (14) Now remove reading of biomass emissions from "carbon_mod.f", since
! they are better done in gc_biomass_mod.f. This will allow us to
! standardize treatment of GFED2 or default BB emissions. Also applied
! a typo fix in SOA_LUMP. (tmf, bmy, 10/16/06)
! (15) Prevent seg fault error in BIOMASS_CARB_GEOS (bmy, 11/3/06)
! (16) Corrected typos in SOA_LUMP. Now also save GPROD and APROD to disk
! for each new diagnostic interval. (dkh, tmv, havala, bmy, 2/6/07)
! (17) Modifications for 0.5 x 0.666 nested grids (yxw, dan, bmy, 11/6/08)
! (18) Now account for various GFED2 products (yc, phs, 12/23/08)
! (19) Now add future scaling to BIOMASS_CARB_GEOS (hotp, swu, 2/19/09)
! (20) Added SOA production from dicarbonyls (tmf, 3/2/09)
! (21) Bugfix: cleanup ORVC_TERP and ORVC_SESQ (tmf, 3/2/09)
! (22) Replace USE_MONTHLY_BIOB with USE_BOND_BIOBURN, since this hardwired
! flag is a switc b/w annual Bond biomass burning emissions, and default
! GC source, which can be monthly/8 days/3hr.
! Implement changes for reading new Bond files (eml, phs, 5/18/09)
! (23) Add option for non-local PBL scheme (lin, 06/09/08)
! (24) Modified to include GFED3 (psk, 1/5/11)

! GEOS-CHEM. (rjp, bmy, 7/8/04, 8/3/06)
!
! Procedure:
! ============================================================================
! (1 ) Read in NO3, O3, OH in CHEM_SOA
! (2 ) Scales these fields using OHNO3TIME in sulfate_mod.f (see GET_OH)
! (3 ) Calculate reaction rates (Serena's OCHEMPARAETER)
! (4 ) CALCULATE DELHC
! (5 ) get T0M gas products
! (6 ) equilibrium calculation
!
! There are total of 42 tracers considered in this routine:
!
! 4 classes of primary carbonaceous aerosols:
! BCPI = Hydrophilic black carbon
! OCPI = Hydrophilic organic carbon
! BCPO = Hydrophobic black carbon
! OCPO = Hydrophobic organic carbon
!
! 6 reactive biogenic hydrocarbon groups (NVOC):
! ALPH = a-pinene, b-pinene, sabinene, carene, terpenoid ketones
! LIMO = limonene
! TERP = a-terpinene, r-terpinene, terpinolene
! ALCO = myrcene, terpenoid alcohols, ocimene
! SESQ = sesquiterpenes
! ISOP = Isoprene
!
! NOTE: TERP and SESQ are not tracers because of their high reactivity
!
! 32 organic oxidation products by O3+OH and NO3:
! 6 ( 3 gases + 3 aerosols ) from each of first four NVOC = 24
! 4 ( 2 gases + 2 aerosols ) from sesquiterpenes oxidation = 4
! 4 ( 2 gases + 2 aerosols ) from isoprene oxidation = 4
!
! NOTE: We aggregate these into 6 tracers according to HC classes
! SOG1 = lump of gas products of first three (ALPH+LIMO+TERP) HC oxidation.
! SOG2 = gas product of ALCO oxidation
! SOG3 = gas product of SESQ oxidation
! SOG4 = gas product of ISOP oxidation
! SOA1 = lump of aerosol products of first 3 (ALPH+LIMO+TERP) HC oxidation.
! SOA2 = aerosol product of ALCO oxidation
! SOA3 = aerosol product of SESQ oxidation
! SOA4 = aerosol product of ISOP oxidation
!
! NOTES:
! (1 ) Now references STT from "tracer_mod.f" (bmy, 7/20/04)
! (2 ) Now modified for SOG4, SOA4 -- products of oxidation by isoprene.
! (dkh, bmy, 6/1/06)
! (3 ) Now consider SOG condensation onto SO4, NH4, NIT aerosols (if SO4,
! NH4, NIT are defined as tracers). (rjp, bmy, 8/3/06)

! Do we have to include other types of aerosols such

! available in ISORROPIA?
!
! I think that aerosol water is valuable information for

! NOTES:
! (1 ) Now references STT from "tracer_mod.f" (bmy, 7/20/04)
! (2 ) Bug fix: make sure L <= LD07 before saving into AD07 array, or else
! we will get an out-of-bounds error. (bmy, 3/4/05)
! (3 ) Now make sure all USE statements are USE, ONLY (bmy, 10/3/05)
! (4 ) Updated for SOG4, SOA4 (dkh, bmy, 5/22/06)
! (5 ) Typo fix: GPROD should be APROD in a couple places (tmf, bmy, 10/16/06)
! (6 ) Bug fix: For SOA4, GPROD and APROD should have default values of 0.5,

!******************************************************************************
! Subroutine BIOGENIC_OC emits secondary organic carbon aerosols.
! Also modified for SOA tracers. (rjp, bmy, 4/1/04, 1/24/08)
!
! Terpene emissions as a source of OC: TERP.GEIA90.a1.2x2.5.*
! Assuming 10% yield of OC(hydrophilic) from terpene emission.
!
! NOTES:
! (1 ) Now separate computation for FULLCHEM and OFFLINE runs (bmy, 7/8/04)
! (2 ) Now references DATA_DIR from "directory_mod.f". Now references LSOA
! from "logical_mod.f". (bmy, 7/20/04)
! (3 ) Now reads data from "carbon_200411" subdir of DATA_DIR (bmy, 11/15/04)
! (4 ) Now can use MEGAN biogenic emissions (tmf, bmy, 10/20/05)
! (5 ) For GCAP, need to use GET_NAME_EXT_2D in NVOC file name (bmy, 4/11/06)
! (6 ) Bug fix: add MEGAN emissions to TERP_ORGC when SOA emissions are
! turned on (dkh, bmy, 1/24/08)
! (7 ) Change LMEGAN switch to LMEGANMONO switch (ccc, 3/2/09)
