5      ==============================      ==============================
6    
7    o diagnostics pkg: change pointers so that 1 diagnostic can be used
8      several times with different frequencies.
9    o mnc-ify the thsice package as requested by Daniel Enderton
10      - the monitor--MNC output needs work
11      - many attributes need to be added (most are currently blank)
12    o mnc-ify theaim_v23 package as requested by Daniel Enderton
13      - many attributes need to be added (most are currently blank)
14    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
15    o add Sadourny like discretization to the 4th.O vorticity advection scheme
16    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
17      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
18         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
19    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
20     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
21    
22    checkpoint57i_post
23    o Diagnostics package was changed: diagnostic allocation is now deactivated
24      by setting an empty file name in the namelist (used to be by setting 0 frequency)
25    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
26      add 1rst Order upwind vertical Shear.
27    o add a quick fix for A/B checkpointing in OFFLINE mode
28    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
29      end-run around the C/Fortran linking horror in eesup/src/timers.F
30    o added pkg/runclock: allows user to terminate run based on wall clock
31    o added non-hydrostatic scaling parameter: nh_am2
32    o pkg/my82: futile attempt to make results compiler-independent by adding
33      some "_d 0", etc. no effect.
34    o for mnc output, fill the 'T' coordinate var with myTime and create a
35      separate 'iter' variable for iteration count
36    o pkg/diagnostics:
37      add new capability: output of Global/Regional & per-level statistics ;
38      tested against monitor output (including land & thSIce) on various exp.
39    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
40    
41    checkpoint57h_done
42      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
43      data.diagnostics, data.gchem, data.ptracers) is done.
44    
45    o pkg/diagnostics: prepare for Global/Regional statistics.
46      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
47    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
48      and rename it: DIFFERENT_MULTIPLE
49    
50    checkpoint57h_post
51    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
52    o pkg/diagnostics: change output frequency, now in seconds (instead
53      of Nb of iterations). This requires to change data.diagnostics.
54    checkpoint57h_pre
55    
56    o in mnc, let the user create the output dir if both mnc_outdir_date
57      and mnc_outdir_num are false
58    o add fflags() to pkg/diagnostics which allows one to specify, on a
59      per-file basis, the file precision [default behavior is unchanged]
60    o added diagnostics to pkg/kpp, including computation of mixed layer
61      depth based on a temperature/density criterion
62    o updated verification/natl_box to test the new pkg/kpp diagnostics
63    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
64    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
65    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
66      not mnc -- this mistake was found by JMC and is now corrected
67    
68    checkpoint57g_post
69    o add Adams-Bashforth 3rd Order time stepping:
70      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
71      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
72    checkpoint57g_pre
73    
74    o make lambda[Theta,Salt]ClimRelax spatially varying
75      (default remains spatially uniform constant based on tau)
76    o added new control variables
77      * init. uVel, vVel, etanN
78      * lambda[Theta,Salt]ClimRelax
79    o separate masks used for ctrl_pack/unpack 'from write_grid' output
80      (suggested by G. Forget)
81    
82    checkpoint57f_post
83    o add parameter "baseTime" = model base time = time at iteration zero
84      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
85      account for baseTime shift
86    o move Coriolis arrays from PARAMS.h to GRID.h
87    checkpoint57f_pre
88    
89    o mnc-ifying the seaice package
90    o introduced an alternative length scale calculation for use in the limiting
91      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
92    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
93    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
94      as well as grad(vort3).  Made it compatible with both approximate form
95      for the cubed sphere and full form of these gradients.  Added flag
96      useFullLeith to select between approximate and full form.  
97    o add "d0" in getcon.F to reduce differences between compilers/platforms
98      update output.txt of exp. fizhi-gridalt-hs
99    o change port_rand funtion to allow to set the seed.
100    o fix obscure MNC bug involving conversion between reals and integers
101      - it caused no problems with certain (eg. gcc, ifc) compilers but the
102        new version is now more standards-compliant
103    o adjoint-related modifications
104      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
105      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
106      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
107    
108    checkpoint57e_post
109    o Adding eddy stress controls a la Ferreira et al.
110    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
111    
112    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
113      update output.txt of exp. fizhi-gridalt-hs
114    o add more "Z" dimensions and associated coordinate vars to MNC
115    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
116    o parameter calendarDumps: when set, approximate months (30-31 days) and years
117      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
118      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
119      months and years.  Requires pkg/cal.
120    o diagnostics: add pickup functionality
121      - off by default for backwards compatibility
122      - current version only uses MDSIO -- MNC will be added
123    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
124    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
125    
126    checkpoint57d_post
127    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
128    o modify verification/ideal_2D_oce so that it tests the creation of mnc
129      output from the diagnostics package
130    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
131    o make genmake2 more portable by using ".$FS" instead of ".f" for more
132      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
133  o add coordinate variables to the MNC output from the diagnostics package  o add coordinate variables to the MNC output from the diagnostics package
134  o change MNC-flags default value: true when useMNC=TRUE  o change MNC-flags default value: true when useMNC=TRUE
135  o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F  o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
