4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
8      that are not cubed-sphere grids
9    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
10    o pkg/ctrl:
11      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
12    o non-hydrostatic (calc_gw.F):
13      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
14      update output of exp. global_ocean.cs32x15.viscA4
15    o remove backward compatibility for thetaMin,phiMin
16      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
17    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
18      interpolated wind field not only for curvilineargrid=.true., but also
19      for a rotated grid (rotateGrid=.true.)
20    o pkg/exf: add capability to bypass interpolation for runoff
21      by setting yet another CPP-flag
22    o eesupp/src, B-grid exchange:
23      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
24    o autodiff
25      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
26      allows to switch to single-prec common blocks;
27      corresponding switch occurs in tamc.h, integer isbyte
28      TAF store directivs "byte" and "kind" seem equivalent;
29      Most tamc.h have been updated correspondingly.
30    
31    checkpoint61i
32    o autodiff:
33      fix autodiff_sore/_restore indices for obcs
34      (spotted by I. Hoteit, M. Mazloff)
35    o pkg/autodiff, pkg/ctrl:
36      Add flag to reduce all tapelev I/O to single-prec.
37      In data.ctrl set
38        doSinglePrecTapelev = .TRUE.
39    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
40      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
41    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
42      real fresh water flux (not yet)
43    o pkg/mdsio & rw:
44     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
45     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
46    o pkg/flt:
47     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
48       init_fixed & ini_varia.
49     - clean-up & simplify linear interpolation S/R:
50       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
51     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
52     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
53     - add vert. coordinate & horiz. indices to output files.
54     - change vertical position in initial condition, from index to depth [m].
55     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
56       (easier to get to a curvilinear grid) ; delX,delY no longer used.
57    o pkg/ggl90: a few modifications:
58     - fix bottom boundary condition, and interpolation of KappaE
59       near top and bottom
60     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
61     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
62     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
63    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
64      (maintain temporary backward compatibility, until next checkpoint)
65    
66    checkpoint61h
67    o pkg/diagnostics with "periodic averaging diagnostics":
68      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
69    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
70    o pkg/obcs: fix loop ranges for balancing code
71    o pkg/flt:
72     - improve criteria for finding which tile owns a float.
73     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
74    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
75      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
76      with ocean biogeo)
77    o pkg/flt:
78     - do some cleaning and fix the restart ;
79     - add output.txt in flt_example/results to get this pkg tested.
80    o genmake2: add an EXTENDED_SRC option and flag.
81       for now, cannot be turned on on command line (only through genmake_local)
82    o pkg/mdsio: read/write vector:
83     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
84     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
85       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
86     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
87      (drop to 4 digits matching for grad). But this test does not look very
88      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
89    
90    checkpoint61g
91    o pkg/flt:
92      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
93       + make OPTIONS file more standard.
94      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
95      - fix _BYTESWAPIO CPP-Flag
96      - standard reading of file-parameter "data.flt"
97      - fix argument list of S/R FLT_RESTART
98      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
99    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
100    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
101      a still unfixed compiler/optimization bug
102    
103    checkpoint61f
104    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
105      update results of global_ocean.cs32x15.icedyn test.
106    o move getcon.F from model/src to pkg/fizhi.
107    o pkg/exf: add parameter for extrapolation of temp up to the surface
108       and option to prevent negative evap (in bulk_largeyeager04 only).
109    o Prather Advection scheme: fix tracer conservation for divergent flow
110      (e.g., when using NonLin Free-Surface).
111    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
112    o gmredi (Visbeck-variable-K):
113     - add more parameters to Visbeck-variable-K.
114     - use a 5 points average for dSigmaR in Visbeck-K calculation
115       (more "homogenous": same stencil and same weights as in dSigmaH)
116     - update output of ideal_2D_oce experiment.
117    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
118      (#undef REAL4_IS_SLOW)
119     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
120       coordinate variable
121     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
122       (surface forcing fields), removes some of the functionality
123     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
124     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
125       probably not all: copy _RS surface flux fields to RL field before
126       calling DIAGNOSTICS_FILL
127     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
128       real*4 (CALL EXCH_*_RS) versions.
129     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
130       (generate new output).
