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