5      ==============================      ==============================
6    
7    o pkg/exch2: filling of face-corner halo regions is optional
8      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
9    
10    checkpoint57l_post
11     tag before updating tutorials (pre-release-2)
12    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
13       for output and interpolation of input fields onto model grid)
14    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
15       Affects results of exp. rotating_tank ; update output.txt.
16    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
17          and taking the square quantity and/or using a fraction-weight field.
18    o fix aim_diagnostics_init.F mate numbers.
19    o add mnc output capability to diagnostics/diagstat and update
20      our cvsignore files for the ACSII output generated
21    
22    checkpoint57k_post
23    o lab_sea now uses diagnostics package and provides a suite of
24      new EXF diagnostics output.
25    
26    checkpoint57j_post
27    o exf
28      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
29        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
30        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
31      * extended diagnostics output
32        - now includes all EXF variables
33        - hs, hl moved to common block
34        - separate S/R for diagnostics, called after ctrl vector is added
35        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
36        - EXFqnet contains true Qnet (i.e. includes qsw)
37      * updated verif. lab_sea, global_with_exf
38      * Rearranging hflux (exf_mapfields -> exf_getforcing)
39        to ensure that diagnostics sees a true EXFqnet
40    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
41    o diagnostics pkg: change pointers so that 1 diagnostic can be used
42      several times with different frequencies.
43    o mnc-ify the thsice package as requested by Daniel Enderton
44      - the monitor--MNC output needs work
45      - many attributes need to be added (most are currently blank)
46    o mnc-ify theaim_v23 package as requested by Daniel Enderton
47      - many attributes need to be added (most are currently blank)
48    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
49    o add Sadourny like discretization to the 4th.O vorticity advection scheme
50    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
51      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
52         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
53    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
54     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
55    
56    checkpoint57i_post
57    o Diagnostics package was changed: diagnostic allocation is now deactivated
58      by setting an empty file name in the namelist (used to be by setting 0 frequency)
59    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
60      add 1rst Order upwind vertical Shear.
61    o add a quick fix for A/B checkpointing in OFFLINE mode
62    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
63      end-run around the C/Fortran linking horror in eesup/src/timers.F
64    o added pkg/runclock: allows user to terminate run based on wall clock
65    o added non-hydrostatic scaling parameter: nh_am2
66    o pkg/my82: futile attempt to make results compiler-independent by adding
67      some "_d 0", etc. no effect.
68    o for mnc output, fill the 'T' coordinate var with myTime and create a
69      separate 'iter' variable for iteration count
70    o pkg/diagnostics:
71      add new capability: output of Global/Regional & per-level statistics ;
72      tested against monitor output (including land & thSIce) on various exp.
73    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
74    
75    checkpoint57h_done
76      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
77      data.diagnostics, data.gchem, data.ptracers) is done.
78    
79    o pkg/diagnostics: prepare for Global/Regional statistics.
80      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
81    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
82      and rename it: DIFFERENT_MULTIPLE
83    
84    checkpoint57h_post
85    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
86    o pkg/diagnostics: change output frequency, now in seconds (instead
87      of Nb of iterations). This requires to change data.diagnostics.
88    checkpoint57h_pre
89    
90    o in mnc, let the user create the output dir if both mnc_outdir_date
91      and mnc_outdir_num are false
92    o add fflags() to pkg/diagnostics which allows one to specify, on a
93      per-file basis, the file precision [default behavior is unchanged]
94    o added diagnostics to pkg/kpp, including computation of mixed layer
95      depth based on a temperature/density criterion
96    o updated verification/natl_box to test the new pkg/kpp diagnostics
97    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
98    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
99    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
100      not mnc -- this mistake was found by JMC and is now corrected
101    
102    checkpoint57g_post
103    o add Adams-Bashforth 3rd Order time stepping:
104      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
105      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
106    checkpoint57g_pre
107    
108    o make lambda[Theta,Salt]ClimRelax spatially varying
109      (default remains spatially uniform constant based on tau)
110    o added new control variables
111      * init. uVel, vVel, etanN
112      * lambda[Theta,Salt]ClimRelax
113    o separate masks used for ctrl_pack/unpack 'from write_grid' output
114      (suggested by G. Forget)
115    
116    checkpoint57f_post
117    o add parameter "baseTime" = model base time = time at iteration zero
118      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
119      account for baseTime shift
120    o move Coriolis arrays from PARAMS.h to GRID.h
121    checkpoint57f_pre
122    
123    o mnc-ifying the seaice package
124    o introduced an alternative length scale calculation for use in the limiting
125      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
126    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
127  o added modified Leith scheme with viscosity proportional to grad(Hdiv)  o added modified Leith scheme with viscosity proportional to grad(Hdiv)
128    as well as grad(vort3).  Made it compatible with both approximate form    as well as grad(vort3).  Made it compatible with both approximate form
