4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/autodiff, pkg/ctrl:
8      Add flag to reduce all tapelev I/O to single-prec.
9      In data.ctrl set
10        doSinglePrecTapelev = .TRUE.
11    o model/src/ini_curvilinear_grid.F: check in hack for SX8 compiler
12      to make sure that recip_dxV and recip_dyU are never zero, until we
13      have a proper exchange for them. Most compilers do not seem
14      to mind divisions by zero in the overlaps, as long as the results are
15      not used anywhere, but sxf90 does.
16    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
17      real fresh water flux (not yet)
18    o pkg/mdsio & rw:
19     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
20     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
21    o pkg/flt:
22     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
23       init_fixed & ini_varia.
24     - clean-up & simplify linear interpolation S/R:
25       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
26     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
27     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
28     - add vert. coordinate & horiz. indices to output files.
29     - change vertical position in initial condition, from index to depth [m].
30     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
31       (easier to get to a curvilinear grid) ; delX,delY no longer used.
32    o pkg/ggl90: a few modifications:
33     - fix bottom boundary condition, and interpolation of KappaE
34       near top and bottom
35     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
36     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
37     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
38    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
39      (maintain temporary backward compatibility, until next checkpoint)
40    
41    checkpoint61h
42    o pkg/diagnostics with "periodic averaging diagnostics":
43      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
44    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
45    o pkg/obcs: fix loop ranges for balancing code
46    o pkg/flt:
47     - improve criteria for finding which tile owns a float.
48     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
49    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
50      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
51      with ocean biogeo)
52    o pkg/flt:
53     - do some cleaning and fix the restart ;
54     - add output.txt in flt_example/results to get this pkg tested.
55    o genmake2: add an EXTENDED_SRC option and flag.
56       for now, cannot be turned on on command line (only through genmake_local)
57    o pkg/mdsio: read/write vector:
58     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
59     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
60       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
61     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
62      (drop to 4 digits matching for grad). But this test does not look very
63      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
64    
65    checkpoint61g
66    o pkg/flt:
67      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
68       + make OPTIONS file more standard.
69      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
70      - fix _BYTESWAPIO CPP-Flag
71      - standard reading of file-parameter "data.flt"
72      - fix argument list of S/R FLT_RESTART
73      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
74    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
75    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
76      a still unfixed compiler/optimization bug
77    
78    checkpoint61f
79    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
80      update results of global_ocean.cs32x15.icedyn test.
81    o move getcon.F from model/src to pkg/fizhi.
82    o pkg/exf: add parameter for extrapolation of temp up to the surface
83       and option to prevent negative evap (in bulk_largeyeager04 only).
84    o Prather Advection scheme: fix tracer conservation for divergent flow
85      (e.g., when using NonLin Free-Surface).
86    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
87    o gmredi (Visbeck-variable-K):
88     - add more parameters to Visbeck-variable-K.
89     - use a 5 points average for dSigmaR in Visbeck-K calculation
90       (more "homogenous": same stencil and same weights as in dSigmaH)
91     - update output of ideal_2D_oce experiment.
92    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
93      (#undef REAL4_IS_SLOW)
94     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
95       coordinate variable
96     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
97       (surface forcing fields), removes some of the functionality
98     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
99     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
100       probably not all: copy _RS surface flux fields to RL field before
101       calling DIAGNOSTICS_FILL
102     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
103       real*4 (CALL EXCH_*_RS) versions.
104     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
105       (generate new output).
106    
107  checkpoint61e  checkpoint61e
108  o gmredi (Visbeck-variable-K):  o gmredi (Visbeck-variable-K):
109    - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h    - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
