5      ==============================      ==============================
6    
7    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
8      and rename it: DIFFERENT_MULTIPLE
9    
10    checkpoint57h_post
11    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
12    o pkg/diagnostics: change output frequency, now in seconds (instead
13      of Nb of iterations). This requires to change data.diagnostics.
14    checkpoint57h_pre
15    
16    o in mnc, let the user create the output dir if both mnc_outdir_date
17      and mnc_outdir_num are false
18    o add fflags() to pkg/diagnostics which allows one to specify, on a
19      per-file basis, the file precision [default behavior is unchanged]
20    o added diagnostics to pkg/kpp, including computation of mixed layer
21      depth based on a temperature/density criterion
22    o updated verification/natl_box to test the new pkg/kpp diagnostics
23    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
24    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
25    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
26      not mnc -- this mistake was found by JMC and is now corrected
27    
28    checkpoint57g_post
29    o add Adams-Bashforth 3rd Order time stepping:
30      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
31      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
32    checkpoint57g_pre
33    
34    o make lambda[Theta,Salt]ClimRelax spatially varying
35      (default remains spatially uniform constant based on tau)
36    o added new control variables
37      * init. uVel, vVel, etanN
38      * lambda[Theta,Salt]ClimRelax
39    o separate masks used for ctrl_pack/unpack 'from write_grid' output
40      (suggested by G. Forget)
41    
42    checkpoint57f_post
43    o add parameter "baseTime" = model base time = time at iteration zero
44      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
45      account for baseTime shift
46    o move Coriolis arrays from PARAMS.h to GRID.h
47    checkpoint57f_pre
48    
49    o mnc-ifying the seaice package
50    o introduced an alternative length scale calculation for use in the limiting
51      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
52    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
53    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
54      as well as grad(vort3).  Made it compatible with both approximate form
55      for the cubed sphere and full form of these gradients.  Added flag
56      useFullLeith to select between approximate and full form.  
57    o add "d0" in getcon.F to reduce differences between compilers/platforms
58      update output.txt of exp. fizhi-gridalt-hs
59    o change port_rand funtion to allow to set the seed.
60    o fix obscure MNC bug involving conversion between reals and integers
61      - it caused no problems with certain (eg. gcc, ifc) compilers but the
62        new version is now more standards-compliant
63    o adjoint-related modifications
64      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
65      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
66      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
67    
68    checkpoint57e_post
69    o Adding eddy stress controls a la Ferreira et al.
70    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
71    
72    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
73      update output.txt of exp. fizhi-gridalt-hs
74    o add more "Z" dimensions and associated coordinate vars to MNC
75    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
76    o parameter calendarDumps: when set, approximate months (30-31 days) and years
77      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
78      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
79      months and years.  Requires pkg/cal.
80    o diagnostics: add pickup functionality
81      - off by default for backwards compatibility
82      - current version only uses MDSIO -- MNC will be added
83    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
84    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
85    
86    checkpoint57d_post
87    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
88    o modify verification/ideal_2D_oce so that it tests the creation of mnc
89      output from the diagnostics package
90    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
91    o make genmake2 more portable by using ".$FS" instead of ".f" for more
92      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
93    o add coordinate variables to the MNC output from the diagnostics package
94    o change MNC-flags default value: true when useMNC=TRUE
95    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
96      the ability (off by default) to read the grid information using MNC
97    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
98    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
99    o do snap-shot diagnostics at the middle of the time-interval (instead of
100      at the end).
101    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
102      new test for AIM with thSIce + slab-ocean
103    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
104    o move state variable diagnostics to the beginning of the time step ;
105      (note: still needs some work specially for snap-shot diagnostics)
106      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
107    
108    checkpoint57c_post
109    o Change testing option (-ieee) to get closer agreement between g77 & ifort
110    o generate new output.txt files on faulks with g77 & the new -ieee option
111    checkpoint57c_pre
112    
113    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
114      update output.txt of exp. global_ocean.90x40x15
115    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
116      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
117    o add saltFlux(+File) forcing capability with periodicExternalForcing
118    o allow to use pkg diagnostics for GM-Redi & ThSIce output
119    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
120    o improvements for the MNC output from DIAGNOSTICS:
121      - correct handling of the unlimitied dimension
122      - all dims now have associated coordinate variables
123      - variables located at U, V, and Corner ("Z") points are now written
124        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
125        *all* data points are output
126    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
127    o added pkg/seaice/seaice_monitor.F
128  o mdsio_readfield.F can now read files visible only to master MPI process.  o mdsio_readfield.F can now read files visible only to master MPI process.
129  o pkg/seaice: some test code for ice-modified ocean stress  o pkg/seaice: some test code for ice-modified ocean stress
130  o exf_getffields interpolation defaults to bilinear for all scalar forcing  o exf_getffields interpolation defaults to bilinear for all scalar forcing

134    o pkg/ctrl/
135      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
136        May be enabled via doPackDiag

139         + control (doZscaleUnpack)
140    o pkg/mdsio/
141      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
