5      ==============================      ==============================
6    
7    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
8          and taking the square quantity and/or using a fraction-weight field.
9    o fix aim_diagnostics_init.F mate numbers.
10    o add mnc output capability to diagnostics/diagstat and update
11      our cvsignore files for the ACSII output generated
12    
13    checkpoint57k_post
14    o lab_sea now uses diagnostics package and provides a suite of
15      new EXF diagnostics output.
16    
17    checkpoint57j_post
18    o exf
19      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
20        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
21        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
22      * extended diagnostics output
23        - now includes all EXF variables
24        - hs, hl moved to common block
25        - separate S/R for diagnostics, called after ctrl vector is added
26        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
27        - EXFqnet contains true Qnet (i.e. includes qsw)
28      * updated verif. lab_sea, global_with_exf
29      * Rearranging hflux (exf_mapfields -> exf_getforcing)
30        to ensure that diagnostics sees a true EXFqnet
31    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
32    o diagnostics pkg: change pointers so that 1 diagnostic can be used
33      several times with different frequencies.
34    o mnc-ify the thsice package as requested by Daniel Enderton
35      - the monitor--MNC output needs work
36      - many attributes need to be added (most are currently blank)
37    o mnc-ify theaim_v23 package as requested by Daniel Enderton
38      - many attributes need to be added (most are currently blank)
39    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
40    o add Sadourny like discretization to the 4th.O vorticity advection scheme
41    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
42      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
43         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
44    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
45     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
46    
47    checkpoint57i_post
48    o Diagnostics package was changed: diagnostic allocation is now deactivated
49      by setting an empty file name in the namelist (used to be by setting 0 frequency)
50    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
51      add 1rst Order upwind vertical Shear.
52    o add a quick fix for A/B checkpointing in OFFLINE mode
53    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
54      end-run around the C/Fortran linking horror in eesup/src/timers.F
55    o added pkg/runclock: allows user to terminate run based on wall clock
56    o added non-hydrostatic scaling parameter: nh_am2
57    o pkg/my82: futile attempt to make results compiler-independent by adding
58      some "_d 0", etc. no effect.
59    o for mnc output, fill the 'T' coordinate var with myTime and create a
60      separate 'iter' variable for iteration count
61    o pkg/diagnostics:
62      add new capability: output of Global/Regional & per-level statistics ;
63      tested against monitor output (including land & thSIce) on various exp.
64    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
65    
66    checkpoint57h_done
67      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
68      data.diagnostics, data.gchem, data.ptracers) is done.
69    
70    o pkg/diagnostics: prepare for Global/Regional statistics.
71      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
72    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
73      and rename it: DIFFERENT_MULTIPLE
74    
75    checkpoint57h_post
76    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
77    o pkg/diagnostics: change output frequency, now in seconds (instead
78      of Nb of iterations). This requires to change data.diagnostics.
79    checkpoint57h_pre
80    
81    o in mnc, let the user create the output dir if both mnc_outdir_date
82      and mnc_outdir_num are false
83    o add fflags() to pkg/diagnostics which allows one to specify, on a
84      per-file basis, the file precision [default behavior is unchanged]
85    o added diagnostics to pkg/kpp, including computation of mixed layer
86      depth based on a temperature/density criterion
87    o updated verification/natl_box to test the new pkg/kpp diagnostics
88    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
89    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
90    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
91      not mnc -- this mistake was found by JMC and is now corrected
92    
93    checkpoint57g_post
94    o add Adams-Bashforth 3rd Order time stepping:
95      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
96      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
97    checkpoint57g_pre
98    
99    o make lambda[Theta,Salt]ClimRelax spatially varying
100      (default remains spatially uniform constant based on tau)
101    o added new control variables
102      * init. uVel, vVel, etanN
103      * lambda[Theta,Salt]ClimRelax
104    o separate masks used for ctrl_pack/unpack 'from write_grid' output
105      (suggested by G. Forget)
106    
107    checkpoint57f_post
108    o add parameter "baseTime" = model base time = time at iteration zero
109      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
110      account for baseTime shift
111    o move Coriolis arrays from PARAMS.h to GRID.h
112    checkpoint57f_pre
113    
114    o mnc-ifying the seaice package
115    o introduced an alternative length scale calculation for use in the limiting
116      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
117    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
118    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
119      as well as grad(vort3).  Made it compatible with both approximate form
120      for the cubed sphere and full form of these gradients.  Added flag
121      useFullLeith to select between approximate and full form.  
122    o add "d0" in getcon.F to reduce differences between compilers/platforms
123      update output.txt of exp. fizhi-gridalt-hs
124    o change port_rand funtion to allow to set the seed.
125    o fix obscure MNC bug involving conversion between reals and integers
126      - it caused no problems with certain (eg. gcc, ifc) compilers but the
127        new version is now more standards-compliant
128    o adjoint-related modifications
129      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
130      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
131      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
132    
133    checkpoint57e_post
134    o Adding eddy stress controls a la Ferreira et al.
135    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
136    
137    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
138      update output.txt of exp. fizhi-gridalt-hs
139    o add more "Z" dimensions and associated coordinate vars to MNC
140    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
141    o parameter calendarDumps: when set, approximate months (30-31 days) and years
142      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
143      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
144      months and years.  Requires pkg/cal.
145    o diagnostics: add pickup functionality
146      - off by default for backwards compatibility
147      - current version only uses MDSIO -- MNC will be added
148    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
149    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
150    
151    checkpoint57d_post
152    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
153    o modify verification/ideal_2D_oce so that it tests the creation of mnc
154      output from the diagnostics package
155    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
156    o make genmake2 more portable by using ".$FS" instead of ".f" for more
157      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
158    o add coordinate variables to the MNC output from the diagnostics package
159    o change MNC-flags default value: true when useMNC=TRUE
160    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
161      the ability (off by default) to read the grid information using MNC
162    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
163    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
164    o do snap-shot diagnostics at the middle of the time-interval (instead of
165      at the end).
166    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
167      new test for AIM with thSIce + slab-ocean
168    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
169    o move state variable diagnostics to the beginning of the time step ;
170      (note: still needs some work specially for snap-shot diagnostics)
171      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z

179      update output.txt of exp. global_ocean.90x40x15
180    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
181      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
182    o add saltFlux(+File) forcing capability with periodicExternalForcing
183  o allow to use pkg diagnostics for GM-Redi & ThSIce output  o allow to use pkg diagnostics for GM-Redi & ThSIce output
