5      ==============================      ==============================
6    
7    o add mnc output capability to diagnostics/diagstat and update
8      our cvsignore files for the ACSII output generated
9    
10    checkpoint57k_post
11    o lab_sea now uses diagnostics package and provides a suite of
12      new EXF diagnostics output.
13    
14    checkpoint57j_post
15    o exf
16      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
17        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
18        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
19      * extended diagnostics output
20        - now includes all EXF variables
21        - hs, hl moved to common block
22        - separate S/R for diagnostics, called after ctrl vector is added
23        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
24        - EXFqnet contains true Qnet (i.e. includes qsw)
25      * updated verif. lab_sea, global_with_exf
26      * Rearranging hflux (exf_mapfields -> exf_getforcing)
27        to ensure that diagnostics sees a true EXFqnet
28    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
29    o diagnostics pkg: change pointers so that 1 diagnostic can be used
30      several times with different frequencies.
31    o mnc-ify the thsice package as requested by Daniel Enderton
32      - the monitor--MNC output needs work
33      - many attributes need to be added (most are currently blank)
34    o mnc-ify theaim_v23 package as requested by Daniel Enderton
35      - many attributes need to be added (most are currently blank)
36    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
37    o add Sadourny like discretization to the 4th.O vorticity advection scheme
38    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
39      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
40         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
41    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
42     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
43    
44    checkpoint57i_post
45    o Diagnostics package was changed: diagnostic allocation is now deactivated
46      by setting an empty file name in the namelist (used to be by setting 0 frequency)
47    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
48      add 1rst Order upwind vertical Shear.
49    o add a quick fix for A/B checkpointing in OFFLINE mode
50    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
51      end-run around the C/Fortran linking horror in eesup/src/timers.F
52    o added pkg/runclock: allows user to terminate run based on wall clock
53    o added non-hydrostatic scaling parameter: nh_am2
54    o pkg/my82: futile attempt to make results compiler-independent by adding
55      some "_d 0", etc. no effect.
56    o for mnc output, fill the 'T' coordinate var with myTime and create a
57      separate 'iter' variable for iteration count
58    o pkg/diagnostics:
59      add new capability: output of Global/Regional & per-level statistics ;
60      tested against monitor output (including land & thSIce) on various exp.
61    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
62    
63    checkpoint57h_done
64      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
65      data.diagnostics, data.gchem, data.ptracers) is done.
66    
67    o pkg/diagnostics: prepare for Global/Regional statistics.
68      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
69    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
70      and rename it: DIFFERENT_MULTIPLE
71    
72    checkpoint57h_post
73    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
74    o pkg/diagnostics: change output frequency, now in seconds (instead
75      of Nb of iterations). This requires to change data.diagnostics.
76    checkpoint57h_pre
77    
78    o in mnc, let the user create the output dir if both mnc_outdir_date
79      and mnc_outdir_num are false
80    o add fflags() to pkg/diagnostics which allows one to specify, on a
81      per-file basis, the file precision [default behavior is unchanged]
82    o added diagnostics to pkg/kpp, including computation of mixed layer
83      depth based on a temperature/density criterion
84    o updated verification/natl_box to test the new pkg/kpp diagnostics
85    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
86    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
87    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
88      not mnc -- this mistake was found by JMC and is now corrected
89    
90    checkpoint57g_post
91    o add Adams-Bashforth 3rd Order time stepping:
92      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
93      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
94    checkpoint57g_pre
95    
96    o make lambda[Theta,Salt]ClimRelax spatially varying
97      (default remains spatially uniform constant based on tau)
98    o added new control variables
99      * init. uVel, vVel, etanN
100      * lambda[Theta,Salt]ClimRelax
101    o separate masks used for ctrl_pack/unpack 'from write_grid' output
102      (suggested by G. Forget)
103    
104    checkpoint57f_post
105    o add parameter "baseTime" = model base time = time at iteration zero
106      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
107      account for baseTime shift
108    o move Coriolis arrays from PARAMS.h to GRID.h
109    checkpoint57f_pre
110    
111    o mnc-ifying the seaice package
112    o introduced an alternative length scale calculation for use in the limiting
113      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
114    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
115    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
116      as well as grad(vort3).  Made it compatible with both approximate form
117      for the cubed sphere and full form of these gradients.  Added flag
118      useFullLeith to select between approximate and full form.  
119    o add "d0" in getcon.F to reduce differences between compilers/platforms
120      update output.txt of exp. fizhi-gridalt-hs
121    o change port_rand funtion to allow to set the seed.
122    o fix obscure MNC bug involving conversion between reals and integers
123      - it caused no problems with certain (eg. gcc, ifc) compilers but the
124        new version is now more standards-compliant
125    o adjoint-related modifications
126      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
127      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
128      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
129    
130    checkpoint57e_post
131    o Adding eddy stress controls a la Ferreira et al.
132    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
133    
134    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
135      update output.txt of exp. fizhi-gridalt-hs
136    o add more "Z" dimensions and associated coordinate vars to MNC
137    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
138    o parameter calendarDumps: when set, approximate months (30-31 days) and years
139      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
140      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
141      months and years.  Requires pkg/cal.
142  o diagnostics: add pickup functionality  o diagnostics: add pickup functionality
143    - off by default for backwards compatibility    - off by default for backwards compatibility
144    - current version only uses MDSIO -- MNC will be added    - current version only uses MDSIO -- MNC will be added
