SUBROUTINE UPBDFLX_O3
!
!******************************************************************************
! Subroutine UPBDFLX_O3 establishes the flux boundary condition for Ozone
! coming down from the stratosphere, using the Synoz algorithm of
! McLinden et al, 2000. (qli, bmy, 12/13/99, 11/6/08)
!
! Reference:
! ===========================================================================
! C. A. McLinden, S. Olsen, B. Hannegan, O. Wild, M. J. Prather, and
! J. Sundet, "Stratospheric Ozone in 3-D models: A simple chemistry
! and the cross-tropopause flux".
!
! NOTES:
! (1 ) The parameter Rdg0 from "CMN_GCTM" = R / g0 = 28.97.
! (2 ) Pass PW = PS - PTOP to UPBDFLX via "CMN".
! (3 ) Now pass IORD, JORD, KORD as arguments (bmy, 12/6/00)
! (4 ) Now compute the proper value of PO3_vmr that will yield 475 Tg O3/yr
! for various settings of IORD, JORD, KORD (rvm, bey, bmy, 12/5/00)
!
! **************************************************************
! ***** You must use this version of UPBDFLX_O3 if you are *****
! ***** using the Parallel Processor TPCORE v. 7.1 *****
! **************************************************************
!
! (5 ) Added to "upbdflx_mod.f". Also updated comments and made some
! cosmetic changes. (bmy, 6/28/01)
! (6 ) Now reference CMN_SETUP for LSPLIT. Also store strat O3 into
! tracer #11 for multi-tracer Ox run. (amf, bmy, 7/3/01)
! (7 ) Removed IREF, JREF -- these are obsolete. Also T(IREF,JREF,L) is
! now T(I,J,L). (bmy, 9/27/01)
! (8 ) Also replace PW(I,J) with P(I,J) (bmy, 10/3/01)
! (9 ) Removed obsolete commented out code from 9/01 (bmy, 10/24/01)
! (10) Removed obsolete commented out code from 7/01 (bmy, 11/26/01)
! (11) Now write file names to stdout (bmy, 4/3/02)
! (12) Replaced all instances of IM with IIPAR and JM with JJPAR, in order
! to prevent namespace confusion for the new TPCORE (bmy, 6/25/02)
! (13) Now use GET_PEDGE and GET_PCENTER from "pressure_mod.f" to compute
! the pressure at the bottom edge and center of grid box (I,J,L).
! Also removed obsolete, commented-out code. Removed G_SIG and
! G_SIGE from the arg list. (dsa, bdf, bmy, 8/21/02)
! (14) Now reference BXHEIGHT and T from "dao_mod.f". Also reference routine
! ERROR_STOP from "error_mod.f". Now references IDTOX from F90 module
! "tracerid_mod.f" instead of from "comtrid.h". (bmy, 11/6/02)
! (15) Now define J30S and J30N for 1x1 nested grid (bmy, 3/11/03)
! (16) Make sure to pass AD via "dao_mod.f" for GEOS-1 (bnd, bmy, 4/14/03)
! (17) On the first timestep, print how much O3 flux is coming down from the
! stratosphere in Tg/yr. (mje, bmy, 8/15/03)
! (18) Change O3 flux to 500 Tg/yr for GEOS-3 (mje, bmy, 9/15/03)
! (19) Now calls routine ADD_STRAT_POX from "tagged_ox_mod.f" in order to
! pass stratospheric flux of Ox to the proper tagged tracer w/o
! resorting to hardwiring w/in this routine. (bmy, 8/18/03)
! (20) Add GEOS_4 to the #if defined block. (bmy, 1/29/04)
! (21) Activated parallel DO-loops. Now made STFLUX a local array
! in order to facilitate parallelization. (bmy, 4/15/04)
! (22) Removed IORD, JORD, KORD from the arg list. Now reference STT and
! ITS_A_TAGOX_SIM from "tracer_mod.f". (bmy, 7/20/04)
! (23) Use an #ifdef block to comment out an EXIT statement from w/in a
! parallel loop for COMPAQ compiler. COMPAQ seems to have some
! problems with this. Now supports 1x125 grid. (auvray, bmy, 12/1/04)
! (24) Now modified for GEOS-5 and GCAP met fields (swu, bmy, 5/25/05)
! (25) Remove support for GEOS-1 and GEOS-STRAT met fields (bmy, 8/4/06)
! (26) Now set J30S and J30N for GEOS-5 nested grid (yxw, dan, bmy, 11/6/08)

SUBROUTINE UPBDFLX_NOY( IFLAG )

!******************************************************************************
! Subroutine UPBDFLX_NOY imposes NOy (NOx + HNO3) upper boundary condition
! in the stratosphere. The production rates for NOy are provided by Dylan
! Jones, along with NOx and HNO3 concentrations.
! (qli, rvm, mje, bmy, 12/22/99, 8/4/06)
!
! Arguments as input:
! ===========================================================================
! (1) IFLAG : IFLAG=1 will partition [NOy] before transport
! IFLAG=2 will re-partition [NOy] after transport
!
! NOTES:
! (1 ) Use READ_BPCH2 to read data from disk in binary punch file format.
! (2 ) Now partition total [NOy] into [NOx] and [HNO3], instead of
! partitioning P(NOy) into P(NOx) and P(HNO3). (qli, bmy, 12/22/1999)
! (3 ) Also echo back to the user when reading data from disk. This
! allows the user to trace I/O errors more easily. (bmy, 2/1/00)
! (4 ) Cosmetic changes, updated comments (bmy, 3/17/00)
! (5 ) Reference F90 module "bpch2_mod" which contains routine "read_bpch2"
! for reading data from binary punch files (bmy, 6/28/00)
! (6 ) Only add P(NOy) above 10mb (archived in files "pnoy_above_10mb.*)
! into the top layer of the GEOS-1 and GEOS-STRAT grids. The GEOS-2
! and GEOS-3 grids extend well above 10mb and so they will contain
! all of the P(NOy) up there (bmy, 6/29/00)
! (7 ) Now use function GET_TAU0 (from "bpch2_mod.f") to return the TAU0
! value used to index the binary punch file. (bmy, 7/20/00)
! (8 ) Only dump P(NOy) above 10mb for GEOS-1 grid. The GEOS-STRAT grid
! will already have this contribution, since it extends to 0.1 mb.
! Also fix regridding error in P(NOy) data file. Add parallel
! processor DO-loops. (rvm, qli, bmy, 12/6/00)
! (9 ) Now scale P(NOy) by 0.7 for TPCORE flags 337, in order to prevent
! excess NOy from building up in the stratosphere. (rvm, bmy, 12/12/00)
! (10) Now read properly regridded P(NOy) files from the pnoy_200106/
! subdirectory of DATA_DIR. Also updated comments and made a
! few cosmetic changes. (mje, bmy, 6/28/01)
! (11) Now use 3 arguments (M/D/Y) in call to GET_TAU0. ARRAY needs to be
! of size (1,JGLOB,LGLOB). Use JGLOB,LGLOB in calls to READ_BPCH2.
! Use TRANSFER_ZONAL (from "transfer_mod.f") to cast from REAL*4 to
! REAL*8 and resize arrays to (JJPAR,LLPAR) (bmy, 9/27/01)
! (12) Removed obsolete commented out code from 9/01 (bmy, 10/24/01)
! (13) Now write file name to stdout (bmy, 4/3/02)
! (14) Now reference ERROR_STOP from "error_mod.f". Also references IDTNOX
! and IDTHNO3 from "tracerid_mod.f". (bmy, 11/6/02)
! (15) Rename MONTHSAVE to LASTMONTH. Now use functions GET_TS_DYN and

! Initial partitioning of [NOy] to [NOx] and [HNO3], before
! transport
!
! We use zonal mean values for stratospheric P(NOy), [NO],
! [NO2], and [HNO3] taken from Dylan Jones' & Hans Schneider's
! 2-D model.
!
! Since P(NOy) above 10mb accounts for almost 50% of the total
! stratospheric production, we also dump P(NOy) above 10 mb
! into the top layer of the model. These values are also
! supplied to us by Dylan Jones.
!
! We make the following assumptions:
!
! (1) [NOx] = [NO] + [NO2]
! (2) [NOy] = [NO] + [NO2] + [HNO3] = [NOx] + [HNO3]
!
! Therefore, in order to obtain [NOx] and [HNO3] from [NOy],
! we must do the partitioning as follows:
!
! (1) [NOy] = P(NOy) + [NOx] + [HNO3]
! = Production of NOy plus current
! concentrations of NOx and HNO3 in the
! given grid box
!
! (2) XRATIO = ( [NO] + [NO2] ) / [NOy]
!
! (3) P(NOx) = P(NOy) * XRATIO
!
! (4) P(HNO3) = P(NOy) * ( 1 - XRATIO )
!
! XRATIO = ( [NO] + [NO2] ) / [NOy] approximates the true
! ratio of [NOx] / [NOy], but is itself not the true ratio,
! since our formulation of [NOy] neglects some additional
! species (e.g. PAN, HNO4, N2O5, R4N2, PPN, PMN).
!
! At some future point we may take the additional constituents
! of [NOy] into account. For now we proceed as outlined above.
