4      ==============================      ==============================
5    
6    o mnc: cleanup "full" files--fixes out-of-memory problem
7    
8    checkpoint55j_post
9    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
10      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
11    o add consistent build directories and .cvsignore files to verification
12    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
13    o make all subroutines 30 or less characters in length for certain older
14      compilers to work (a thorough search only turns up two routines in
15      pkg/ptracers)
16    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
17      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
18    
19    checkpoint55i_post
20    o change arrays for total vertical diffusivity (2.D if explicit,
21      3.D if implicit) ; each ptracer uses its own background value.
22    o added mnc/NetCDF output capability to ocn_compon_interf
23      - added bits to verification/cpl_aim+ocn so that it can run on
24        ITRDA and other clusters without the mpirun "-wd" option
25    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
26      configuration
27    o give MNC the ability to create additional files rather than
28      exceeding a specified file size limit "MNC_MAX_FILESIZE"
29      - the default is just less than 2GB which is a practical limit
30        on many systems
31    o Compute the non-local term using either KPP vertical diffusivity (=default)
32       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
33    
34    checkpoint55h_post
35    o add verification test "vermix"
36    o remove all the *_ioinc flags and replace with the single global
37      outputTypesInclusive flag
38    o allow to set a vertical profile of vertical diffusivity for T & S
39    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
40    o useMNC moved from data.mnc to data.pkg
41    
42    checkpoint55g_post
43    o Renaming carbon AD experiments to comply with testreport conventions
44    o Updating adjoint of Held-Suarez hs94.1x64x5
45    o Fixing directives for non-ECCO forward_step, after ECCO directives
46      have been fixed to avoid recomp. of do_oceanic_phys
47      Works well for global_ocean.90x40x15,
48      but recomp. issue remains for carbon
49    o Updating adjoint output for natl_box_adjoint after
50      pkg/ecco has been modified (see taga c55d_post)
51    
52    checkpoint55f_post
53    o rename to timeave_init_fixed
54    
55    checkpoint55e_post
56    o some delicate re-shuffle of store directives to avoid one
57      extra call of do_oceanic_physics
58      affects ecco_the_main_loop.F, do_oceanic_physics.F
59      checkpoint_lev1_directives.h
60    o NB: this may break global_ocean adjoint temporarily,
61      but it is clear how to fix it. Will do later, need this now.
62    
63    checkpoint55d_post
64    o ECCO specific cost function terms (up-to-date with 1x1 runs)
65    o ecco_cost_weights is modified to 1x1 runs
66    o modifs to allow observations to be read in as
67      single file or yearly files
68    o enable to read exf forcing fields as either
69      single file or yearly files (flag useExfYearlyFields)
70    checkpoint55d_pre
71    
72    o switch between 2-level and 3-level checkpointing
73    o add ability of MNC to write local and "partial" (eg. 2D slices where
74      the full 3D field is never actually stored) arrays to NetCDF files
75      with the correct (that is, the complete multi-dimensional) set of
76      array indicies
77      - used in mom_vecinv() to write the diagFreq output
78      - tested (demonstrated) in verification/aim.5l_cs
79    o further mnc-ification
80      - add verification/lab_sea to the list with mnc setups
81      - fix undefined mnc v-names in cd_code
82      - add kpp to mnc output (both snapshot and timeave)
83    o non-hydrostatic code
84      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
85        in calc_gw.F
86      - defaults to viscAh
87      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
88        friction or Leith) in non-hydrostatic mode, as long as there is
89        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
90    o pkg/cost
91      extend simple cost functions to treat time mean quantities
92      (T,U,V) via cost_accumulate_state from cost_tile
93    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
94        be 2 times larger than the minimum size the advection scheme requires.
95        now get a perfect conservation of salt in advect_cs test-exp (updated)
96    o GGL90 (Gaspar's TKE mixed layer)
97      - add horizontal diffusion of TKE, requires exchanges in
98        do_fields_blocking_exchanges, horizontal diffusivity is zero by
99        default. In OPA there is no horizontal diffusion of TKE but the
100        mixing coefficients are computed from a horizontal average of TKE of
101        6 points or so. I think that diffusion has a little more physical
102        justification.
103      - clean up ggl90_calc in the hope of reducing memory usage (this hope
104        was in vain)
105      - mask tke-variable in ggl90_init
106    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
107    o fix biharmonic diffusion on CS-grid.
108  o more obcs stuff  o more obcs stuff
109    - added obcs_external_fields_load as an alternative to the EXF-pkg option    - added obcs_external_fields_load as an alternative to the EXF-pkg option
110      for reading boundary values. This routine is called from      for reading boundary values. This routine is called from
111      obcs_prescribe_read      obcs_prescribe_read
112    - updated obcs_check    - updated obcs_check
113      - changed sponge layer relaxation parameter units for days to seconds
114      - turned off sponge layer by default
115      - changed argument list of OBCS_CALC to myTime+deltaTclock
116      - fixed about 35 bugs in obcs_external_fields_load
117

119  o obcs stuff  o obcs stuff
