5      ==============================      ==============================
6    
7    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
8      (was already the case for dissipation with mom_vecinv,
9       and also the case for grad.PhiHyd when staggered-timeStep)
10      This will allow to put dissipation out-off the AB time-stepping.
11     Unfortunately, affects truncation error. Update output of exp. that "fails"
12      (cg2d matching number) and leave the others for later: front_relax(10),
13      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
14      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
15    
16    checkpoint57o_post
17    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
18      (2) its ready to be documented during the 20050801 DocFest
19    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
20      for ideal_2D_oce and lab_sea on linux_ia32_g77
21    o set to #undef CTRL_SET_OLD_MAXCVARS_30
22      in global1x1_tot/code_seaice_adj to access indices 32, 33
23      (worth another tag)
24    
25    checkpoint57n_post
26    o adding precip control xx_precip 32
27    o adding swflux control xx_swflux 33
28    o Replacing 10 forcing penalty cost routines by 1 generic.
29    o Implementing partitioning in time-mean and variable adjustment
30      for atmos. state.
31    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
32    o in natl_box_adjoint:
33      * updated exp 1 to 10
34        (but does not have time-mean vs. variable split results yet)
35    o updated global1x1/*_seaice_adj/
36      to incorporate latest changes
37    o enable useSingleCpuIO for mdsio vector routines
38      (applies in particular to tapelev I/O)
39    o removed inefficient K-loop in all active_file*control*.F
40    
41    checkpoint57m_post
42    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
43      and advect_cs (use EXCH-2 and standard cs-32 grid files).
44    o pkg/exch2: filling of face-corner halo regions is optional
45      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
46    
47    checkpoint57l_post
48     tag before updating tutorials (pre-release-2)
49    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
50       for output and interpolation of input fields onto model grid)
51    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
52       Affects results of exp. rotating_tank ; update output.txt.
53    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
54          and taking the square quantity and/or using a fraction-weight field.
55    o fix aim_diagnostics_init.F mate numbers.
56    o add mnc output capability to diagnostics/diagstat and update
57      our cvsignore files for the ACSII output generated
58    
59    checkpoint57k_post
60    o lab_sea now uses diagnostics package and provides a suite of
61      new EXF diagnostics output.
62    
63    checkpoint57j_post
64    o exf
65      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
66        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
67        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
68      * extended diagnostics output
69        - now includes all EXF variables
70        - hs, hl moved to common block
71        - separate S/R for diagnostics, called after ctrl vector is added
72        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
73        - EXFqnet contains true Qnet (i.e. includes qsw)
74      * updated verif. lab_sea, global_with_exf
75      * Rearranging hflux (exf_mapfields -> exf_getforcing)
76        to ensure that diagnostics sees a true EXFqnet
77    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
78    o diagnostics pkg: change pointers so that 1 diagnostic can be used
79      several times with different frequencies.
80    o mnc-ify the thsice package as requested by Daniel Enderton
81      - the monitor--MNC output needs work
82      - many attributes need to be added (most are currently blank)
83    o mnc-ify theaim_v23 package as requested by Daniel Enderton
84      - many attributes need to be added (most are currently blank)
85    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
86    o add Sadourny like discretization to the 4th.O vorticity advection scheme
87    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
88      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
89         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
90    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
91     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
92    
93    checkpoint57i_post
94    o Diagnostics package was changed: diagnostic allocation is now deactivated
95      by setting an empty file name in the namelist (used to be by setting 0 frequency)
96    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
97      add 1rst Order upwind vertical Shear.
98    o add a quick fix for A/B checkpointing in OFFLINE mode
99    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
100      end-run around the C/Fortran linking horror in eesup/src/timers.F
101    o added pkg/runclock: allows user to terminate run based on wall clock
102    o added non-hydrostatic scaling parameter: nh_am2
103    o pkg/my82: futile attempt to make results compiler-independent by adding
104      some "_d 0", etc. no effect.
105    o for mnc output, fill the 'T' coordinate var with myTime and create a
106      separate 'iter' variable for iteration count
107    o pkg/diagnostics:
108      add new capability: output of Global/Regional & per-level statistics ;
109      tested against monitor output (including land & thSIce) on various exp.
110    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
111    
112    checkpoint57h_done
113      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
114      data.diagnostics, data.gchem, data.ptracers) is done.
115    
116    o pkg/diagnostics: prepare for Global/Regional statistics.
117      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
118    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
119      and rename it: DIFFERENT_MULTIPLE
120    
121    checkpoint57h_post
122    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
123    o pkg/diagnostics: change output frequency, now in seconds (instead
124      of Nb of iterations). This requires to change data.diagnostics.
125    checkpoint57h_pre
126    
127    o in mnc, let the user create the output dir if both mnc_outdir_date
128      and mnc_outdir_num are false
129    o add fflags() to pkg/diagnostics which allows one to specify, on a
130      per-file basis, the file precision [default behavior is unchanged]
131    o added diagnostics to pkg/kpp, including computation of mixed layer
132      depth based on a temperature/density criterion
133    o updated verification/natl_box to test the new pkg/kpp diagnostics
134    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
135    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
136    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
137      not mnc -- this mistake was found by JMC and is now corrected
138    
139    checkpoint57g_post
140    o add Adams-Bashforth 3rd Order time stepping:
141      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
142      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
143    checkpoint57g_pre
144    
145    o make lambda[Theta,Salt]ClimRelax spatially varying
146      (default remains spatially uniform constant based on tau)
147    o added new control variables
148      * init. uVel, vVel, etanN
149      * lambda[Theta,Salt]ClimRelax
150    o separate masks used for ctrl_pack/unpack 'from write_grid' output
151      (suggested by G. Forget)
152
