7    checkpoint57j_post
8    o exf
9      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
10        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
11        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
12      * extended diagnostics output
13        - now includes all EXF variables
14        - hs, hl moved to common block
15        - separate S/R for diagnostics, called after ctrl vector is added
16        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
17        - EXFqnet contains true Qnet (i.e. includes qsw)
18      * updated verif. lab_sea, global_with_exf
19      * Rearranging hflux (exf_mapfields -> exf_getforcing)
20        to ensure that diagnostics sees a true EXFqnet
21    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
22    o diagnostics pkg: change pointers so that 1 diagnostic can be used
23      several times with different frequencies.
24    o mnc-ify the thsice package as requested by Daniel Enderton
25      - the monitor--MNC output needs work
26      - many attributes need to be added (most are currently blank)
27    o mnc-ify theaim_v23 package as requested by Daniel Enderton
28      - many attributes need to be added (most are currently blank)
29    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
30    o add Sadourny like discretization to the 4th.O vorticity advection scheme
31    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
32      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
33         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
34    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
35     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
36    
37    checkpoint57i_post
38    o Diagnostics package was changed: diagnostic allocation is now deactivated
39      by setting an empty file name in the namelist (used to be by setting 0 frequency)
40    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
41      add 1rst Order upwind vertical Shear.
42    o add a quick fix for A/B checkpointing in OFFLINE mode
43    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
44      end-run around the C/Fortran linking horror in eesup/src/timers.F
45    o added pkg/runclock: allows user to terminate run based on wall clock
46    o added non-hydrostatic scaling parameter: nh_am2
47    o pkg/my82: futile attempt to make results compiler-independent by adding
48      some "_d 0", etc. no effect.
49    o for mnc output, fill the 'T' coordinate var with myTime and create a
50      separate 'iter' variable for iteration count
51    o pkg/diagnostics:
52      add new capability: output of Global/Regional & per-level statistics ;
53      tested against monitor output (including land & thSIce) on various exp.
54    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
55    
56    checkpoint57h_done
57      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
58      data.diagnostics, data.gchem, data.ptracers) is done.
59    
60    o pkg/diagnostics: prepare for Global/Regional statistics.
61      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
62    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
63      and rename it: DIFFERENT_MULTIPLE
64    
65    checkpoint57h_post
66    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
67    o pkg/diagnostics: change output frequency, now in seconds (instead
68      of Nb of iterations). This requires to change data.diagnostics.
69    checkpoint57h_pre
70    
71    o in mnc, let the user create the output dir if both mnc_outdir_date
72      and mnc_outdir_num are false
73    o add fflags() to pkg/diagnostics which allows one to specify, on a
74      per-file basis, the file precision [default behavior is unchanged]
75    o added diagnostics to pkg/kpp, including computation of mixed layer
76      depth based on a temperature/density criterion
77    o updated verification/natl_box to test the new pkg/kpp diagnostics
78    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
79    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
80    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
81      not mnc -- this mistake was found by JMC and is now corrected
82    
83    checkpoint57g_post
84    o add Adams-Bashforth 3rd Order time stepping:
85      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
86      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
87    checkpoint57g_pre
88    
89    o make lambda[Theta,Salt]ClimRelax spatially varying
90      (default remains spatially uniform constant based on tau)
91    o added new control variables
92      * init. uVel, vVel, etanN
93      * lambda[Theta,Salt]ClimRelax
94    o separate masks used for ctrl_pack/unpack 'from write_grid' output
95      (suggested by G. Forget)
96    
97    checkpoint57f_post
98    o add parameter "baseTime" = model base time = time at iteration zero
99      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
100      account for baseTime shift
101    o move Coriolis arrays from PARAMS.h to GRID.h
102    checkpoint57f_pre
103    
104    o mnc-ifying the seaice package
105    o introduced an alternative length scale calculation for use in the limiting
106      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
107    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
108    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
109      as well as grad(vort3).  Made it compatible with both approximate form
110      for the cubed sphere and full form of these gradients.  Added flag
111      useFullLeith to select between approximate and full form.  
112    o add "d0" in getcon.F to reduce differences between compilers/platforms
113      update output.txt of exp. fizhi-gridalt-hs
114    o change port_rand funtion to allow to set the seed.
115    o fix obscure MNC bug involving conversion between reals and integers
116      - it caused no problems with certain (eg. gcc, ifc) compilers but the
117        new version is now more standards-compliant
118    o adjoint-related modifications
119      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
120      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
121      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
122    
123    checkpoint57e_post
124    o Adding eddy stress controls a la Ferreira et al.
125    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
126    
127    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
128      update output.txt of exp. fizhi-gridalt-hs
129    o add more "Z" dimensions and associated coordinate vars to MNC
130    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
131    o parameter calendarDumps: when set, approximate months (30-31 days) and years
132      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
133      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
134      months and years.  Requires pkg/cal.
135    o diagnostics: add pickup functionality
136      - off by default for backwards compatibility
137      - current version only uses MDSIO -- MNC will be added
138    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
139    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
140    
141    checkpoint57d_post
142    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
143    o modify verification/ideal_2D_oce so that it tests the creation of mnc
144      output from the diagnostics package
145    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
146    o make genmake2 more portable by using ".$FS" instead of ".f" for more
147      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
148    o add coordinate variables to the MNC output from the diagnostics package
149    o change MNC-flags default value: true when useMNC=TRUE
150    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
151      the ability (off by default) to read the grid information using MNC
152    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
153    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
154    o do snap-shot diagnostics at the middle of the time-interval (instead of
155      at the end).
156    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
157      new test for AIM with thSIce + slab-ocean
158    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
159    o move state variable diagnostics to the beginning of the time step ;
160      (note: still needs some work specially for snap-shot diagnostics)
161      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
162    
163    checkpoint57c_post
164    o Change testing option (-ieee) to get closer agreement between g77 & ifort

169      update output.txt of exp. global_ocean.90x40x15
170    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
171      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
172    o add saltFlux(+File) forcing capability with periodicExternalForcing
173    o allow to use pkg diagnostics for GM-Redi & ThSIce output
174    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
