5      ==============================      ==============================
6    
7    checkpoint57i_post
8    o Diagnostics package was changed: diagnostic allocation is now deactivated
9      by setting an empty file name in the namelist (used to be by setting 0 frequency)
10    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
11      add 1rst Order upwind vertical Shear.
12    o add a quick fix for A/B checkpointing in OFFLINE mode
13    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
14      end-run around the C/Fortran linking horror in eesup/src/timers.F
15    o added pkg/runclock: allows user to terminate run based on wall clock
16    o added non-hydrostatic scaling parameter: nh_am2
17    o pkg/my82: futile attempt to make results compiler-independent by adding
18      some "_d 0", etc. no effect.
19    o for mnc output, fill the 'T' coordinate var with myTime and create a
20      separate 'iter' variable for iteration count
21    o pkg/diagnostics:
22      add new capability: output of Global/Regional & per-level statistics ;
23      tested against monitor output (including land & thSIce) on various exp.
24    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
25    
26    checkpoint57h_done
27      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
28      data.diagnostics, data.gchem, data.ptracers) is done.
29    
30    o pkg/diagnostics: prepare for Global/Regional statistics.
31      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
32    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
33      and rename it: DIFFERENT_MULTIPLE
34    
35    checkpoint57h_post
36    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
37    o pkg/diagnostics: change output frequency, now in seconds (instead
38      of Nb of iterations). This requires to change data.diagnostics.
39    checkpoint57h_pre
40    
41    o in mnc, let the user create the output dir if both mnc_outdir_date
42      and mnc_outdir_num are false
43    o add fflags() to pkg/diagnostics which allows one to specify, on a
44      per-file basis, the file precision [default behavior is unchanged]
45    o added diagnostics to pkg/kpp, including computation of mixed layer
46      depth based on a temperature/density criterion
47    o updated verification/natl_box to test the new pkg/kpp diagnostics
48    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
49    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
50    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
51      not mnc -- this mistake was found by JMC and is now corrected
52    
53    checkpoint57g_post
54    o add Adams-Bashforth 3rd Order time stepping:
55      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
56      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
57    checkpoint57g_pre
58    
59    o make lambda[Theta,Salt]ClimRelax spatially varying
60      (default remains spatially uniform constant based on tau)
61    o added new control variables
62      * init. uVel, vVel, etanN
63      * lambda[Theta,Salt]ClimRelax
64    o separate masks used for ctrl_pack/unpack 'from write_grid' output
65      (suggested by G. Forget)
66    
67    checkpoint57f_post
68    o add parameter "baseTime" = model base time = time at iteration zero
69      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
70      account for baseTime shift
71    o move Coriolis arrays from PARAMS.h to GRID.h
72    checkpoint57f_pre
73    
74    o mnc-ifying the seaice package
75    o introduced an alternative length scale calculation for use in the limiting
76      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
77    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
78    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
79      as well as grad(vort3).  Made it compatible with both approximate form
80      for the cubed sphere and full form of these gradients.  Added flag
81      useFullLeith to select between approximate and full form.  
82    o add "d0" in getcon.F to reduce differences between compilers/platforms
83      update output.txt of exp. fizhi-gridalt-hs
84    o change port_rand funtion to allow to set the seed.
85    o fix obscure MNC bug involving conversion between reals and integers
86      - it caused no problems with certain (eg. gcc, ifc) compilers but the
87        new version is now more standards-compliant
88    o adjoint-related modifications
89      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
90      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
91      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
92    
93    checkpoint57e_post
94    o Adding eddy stress controls a la Ferreira et al.
95    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
96    
97    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
98      update output.txt of exp. fizhi-gridalt-hs
99    o add more "Z" dimensions and associated coordinate vars to MNC
100    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
101    o parameter calendarDumps: when set, approximate months (30-31 days) and years
102      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
103      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
104      months and years.  Requires pkg/cal.
105    o diagnostics: add pickup functionality
106      - off by default for backwards compatibility
107      - current version only uses MDSIO -- MNC will be added
108    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
109    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
110    
111    checkpoint57d_post
112    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
113    o modify verification/ideal_2D_oce so that it tests the creation of mnc
114      output from the diagnostics package
115  o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up  o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
