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

135    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
