5      ==============================      ==============================
6    
7    o pkg/my82: futile attempt to make results compiler-independent by adding
8      some "_d 0", etc. no effect.
9    o for mnc output, fill the 'T' coordinate var with myTime and create a
10      separate 'iter' variable for iteration count
11    o pkg/diagnostics:
12      add new capability: output of Global/Regional & per-level statistics ;
13      tested against monitor output (including land & thSIce) on various exp.
14    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
15    
16    checkpoint57h_done
17      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
18      data.diagnostics, data.gchem, data.ptracers) is done.
19    
20    o pkg/diagnostics: prepare for Global/Regional statistics.
21      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
22    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
23      and rename it: DIFFERENT_MULTIPLE
24    
25    checkpoint57h_post
26    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
27    o pkg/diagnostics: change output frequency, now in seconds (instead
28      of Nb of iterations). This requires to change data.diagnostics.
29    checkpoint57h_pre
30    
31    o in mnc, let the user create the output dir if both mnc_outdir_date
32      and mnc_outdir_num are false
33    o add fflags() to pkg/diagnostics which allows one to specify, on a
34      per-file basis, the file precision [default behavior is unchanged]
35    o added diagnostics to pkg/kpp, including computation of mixed layer
36      depth based on a temperature/density criterion
37    o updated verification/natl_box to test the new pkg/kpp diagnostics
38    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
39    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
40    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
41      not mnc -- this mistake was found by JMC and is now corrected
42    
43    checkpoint57g_post
44    o add Adams-Bashforth 3rd Order time stepping:
45      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
46      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
47    checkpoint57g_pre
48    
49    o make lambda[Theta,Salt]ClimRelax spatially varying
50      (default remains spatially uniform constant based on tau)
51    o added new control variables
52      * init. uVel, vVel, etanN
53      * lambda[Theta,Salt]ClimRelax
54    o separate masks used for ctrl_pack/unpack 'from write_grid' output
55      (suggested by G. Forget)
56    
57    checkpoint57f_post
58    o add parameter "baseTime" = model base time = time at iteration zero
59      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
60      account for baseTime shift
61    o move Coriolis arrays from PARAMS.h to GRID.h
62    checkpoint57f_pre
63    
64    o mnc-ifying the seaice package
65    o introduced an alternative length scale calculation for use in the limiting
66      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
67    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
68    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
69      as well as grad(vort3).  Made it compatible with both approximate form
70      for the cubed sphere and full form of these gradients.  Added flag
71      useFullLeith to select between approximate and full form.  
72    o add "d0" in getcon.F to reduce differences between compilers/platforms
73      update output.txt of exp. fizhi-gridalt-hs
74    o change port_rand funtion to allow to set the seed.
75    o fix obscure MNC bug involving conversion between reals and integers
76      - it caused no problems with certain (eg. gcc, ifc) compilers but the
77        new version is now more standards-compliant
78    o adjoint-related modifications
79      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
80      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
81      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
82    
83    checkpoint57e_post
84    o Adding eddy stress controls a la Ferreira et al.
85    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
86    
87    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
88      update output.txt of exp. fizhi-gridalt-hs
89    o add more "Z" dimensions and associated coordinate vars to MNC
90    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
91    o parameter calendarDumps: when set, approximate months (30-31 days) and years
92      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
93      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
94      months and years.  Requires pkg/cal.
95    o diagnostics: add pickup functionality
96      - off by default for backwards compatibility
97      - current version only uses MDSIO -- MNC will be added
98    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
99    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
100    
101    checkpoint57d_post
102    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
103    o modify verification/ideal_2D_oce so that it tests the creation of mnc
104      output from the diagnostics package
105    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
106    o make genmake2 more portable by using ".$FS" instead of ".f" for more
107      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
108    o add coordinate variables to the MNC output from the diagnostics package
109    o change MNC-flags default value: true when useMNC=TRUE
110    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
111      the ability (off by default) to read the grid information using MNC
112    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
113    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
114    o do snap-shot diagnostics at the middle of the time-interval (instead of
115      at the end).
116  o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add  o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
117    new test for AIM with thSIce + slab-ocean    new test for AIM with thSIce + slab-ocean
118  o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)  o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
