5      ==============================      ==============================
6    
7    o add fflags() to pkg/diagnostics which allows one to specify, on a
8      per-file basis, the file precision [default behavior is unchanged]
9    o added diagnostics to pkg/kpp, including computation of mixed layer
10      depth based on a temperature/density criterion
11    o updated verification/natl_box to test the new pkg/kpp diagnostics
12    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
13    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
14    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
15      not mnc -- this mistake was found by JMC and is now corrected
16    
17    checkpoint57g_post
18    o add Adams-Bashforth 3rd Order time stepping:
19      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
20      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
21    checkpoint57g_pre
22    
23    o make lambda[Theta,Salt]ClimRelax spatially varying
24      (default remains spatially uniform constant based on tau)
25    o added new control variables
26      * init. uVel, vVel, etanN
27      * lambda[Theta,Salt]ClimRelax
28    o separate masks used for ctrl_pack/unpack 'from write_grid' output
29      (suggested by G. Forget)
30    
31    checkpoint57f_post
32    o add parameter "baseTime" = model base time = time at iteration zero
33      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
34      account for baseTime shift
35    o move Coriolis arrays from PARAMS.h to GRID.h
36    checkpoint57f_pre
37    
38    o mnc-ifying the seaice package
39    o introduced an alternative length scale calculation for use in the limiting
40      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
41    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
42    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
43      as well as grad(vort3).  Made it compatible with both approximate form
44      for the cubed sphere and full form of these gradients.  Added flag
45      useFullLeith to select between approximate and full form.  
46    o add "d0" in getcon.F to reduce differences between compilers/platforms
47      update output.txt of exp. fizhi-gridalt-hs
48    o change port_rand funtion to allow to set the seed.
49    o fix obscure MNC bug involving conversion between reals and integers
50      - it caused no problems with certain (eg. gcc, ifc) compilers but the
51        new version is now more standards-compliant
52    o adjoint-related modifications
53      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
54      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
55      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
56    
57    checkpoint57e_post
58    o Adding eddy stress controls a la Ferreira et al.
59    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
60    
61    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
62      update output.txt of exp. fizhi-gridalt-hs
63    o add more "Z" dimensions and associated coordinate vars to MNC
64    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
65    o parameter calendarDumps: when set, approximate months (30-31 days) and years
66      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
67      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
68      months and years.  Requires pkg/cal.
69    o diagnostics: add pickup functionality
70      - off by default for backwards compatibility
71      - current version only uses MDSIO -- MNC will be added
72    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
73    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
74    
75    checkpoint57d_post
76    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
77    o modify verification/ideal_2D_oce so that it tests the creation of mnc
78      output from the diagnostics package
79    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
80    o make genmake2 more portable by using ".$FS" instead of ".f" for more
81      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
82    o add coordinate variables to the MNC output from the diagnostics package
83    o change MNC-flags default value: true when useMNC=TRUE
84  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
85    the ability (off by default) to read the grid information using MNC    the ability (off by default) to read the grid information using MNC
86    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
87  o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging  o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
88  o do snap-shot diagnostics at the middle of the time-interval (instead of  o do snap-shot diagnostics at the middle of the time-interval (instead of
