5      ==============================      ==============================
6    
7    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
8    o diagnostics pkg: change pointers so that 1 diagnostic can be used
9      several times with different frequencies.
10    o mnc-ify the thsice package as requested by Daniel Enderton
11      - the monitor--MNC output needs work
12      - many attributes need to be added (most are currently blank)
13    o mnc-ify theaim_v23 package as requested by Daniel Enderton
14      - many attributes need to be added (most are currently blank)
15    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
16    o add Sadourny like discretization to the 4th.O vorticity advection scheme
17    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
18      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
19         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
20    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
21     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
22    
23    checkpoint57i_post
24    o Diagnostics package was changed: diagnostic allocation is now deactivated
25      by setting an empty file name in the namelist (used to be by setting 0 frequency)
26    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
27      add 1rst Order upwind vertical Shear.
28    o add a quick fix for A/B checkpointing in OFFLINE mode
29    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
30      end-run around the C/Fortran linking horror in eesup/src/timers.F
31    o added pkg/runclock: allows user to terminate run based on wall clock
32    o added non-hydrostatic scaling parameter: nh_am2
33    o pkg/my82: futile attempt to make results compiler-independent by adding
34      some "_d 0", etc. no effect.
35    o for mnc output, fill the 'T' coordinate var with myTime and create a
36      separate 'iter' variable for iteration count
37    o pkg/diagnostics:
38      add new capability: output of Global/Regional & per-level statistics ;
39      tested against monitor output (including land & thSIce) on various exp.
40    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
41    
42    checkpoint57h_done
43      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
44      data.diagnostics, data.gchem, data.ptracers) is done.
45    
46    o pkg/diagnostics: prepare for Global/Regional statistics.
47      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
48    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
49      and rename it: DIFFERENT_MULTIPLE
50    
51    checkpoint57h_post
52    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
53    o pkg/diagnostics: change output frequency, now in seconds (instead
54      of Nb of iterations). This requires to change data.diagnostics.
55    checkpoint57h_pre
56    
57    o in mnc, let the user create the output dir if both mnc_outdir_date
58      and mnc_outdir_num are false
59    o add fflags() to pkg/diagnostics which allows one to specify, on a
60      per-file basis, the file precision [default behavior is unchanged]
61    o added diagnostics to pkg/kpp, including computation of mixed layer
62      depth based on a temperature/density criterion
63    o updated verification/natl_box to test the new pkg/kpp diagnostics
64    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
65    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
66    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
67      not mnc -- this mistake was found by JMC and is now corrected
68    
69    checkpoint57g_post
70    o add Adams-Bashforth 3rd Order time stepping:
71      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
72      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
73    checkpoint57g_pre
74    
75    o make lambda[Theta,Salt]ClimRelax spatially varying
76      (default remains spatially uniform constant based on tau)
77    o added new control variables
78      * init. uVel, vVel, etanN
79      * lambda[Theta,Salt]ClimRelax
80    o separate masks used for ctrl_pack/unpack 'from write_grid' output
81      (suggested by G. Forget)
82    
83    checkpoint57f_post
84    o add parameter "baseTime" = model base time = time at iteration zero
85      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
86      account for baseTime shift
87    o move Coriolis arrays from PARAMS.h to GRID.h
88    checkpoint57f_pre
89    
90    o mnc-ifying the seaice package
91    o introduced an alternative length scale calculation for use in the limiting
92      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
93    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
94    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
95      as well as grad(vort3).  Made it compatible with both approximate form
96      for the cubed sphere and full form of these gradients.  Added flag
97      useFullLeith to select between approximate and full form.  
98    o add "d0" in getcon.F to reduce differences between compilers/platforms
99      update output.txt of exp. fizhi-gridalt-hs
100    o change port_rand funtion to allow to set the seed.
101  o fix obscure MNC bug involving conversion between reals and integers  o fix obscure MNC bug involving conversion between reals and integers

104    o adjoint-related modifications
105      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
106      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
107      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
