5      ==============================      ==============================
6    
7    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
8      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
9    
10    checkpoint57q_post
11    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
12    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
13      - bug was reported by Jean-Michel and Ian Fenty
14    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
15      update exp. cpl_aim+ocn output.
16    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
17      Needed for high-res. runs with large global files
18      to be able to limit tapelev size
19    o Changed some tests for adjoint:
20      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
21      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
22      * global_ocean.90x40x15/ back to default 3-level checkpointing
23    o Modifications to enable scripted COMMON to MODULE conversion
24      * verification/OpenAD/code/ has necessary scripts and description;
25      * converts, compiles and runs successfully;
26    
27    checkpoint57p_post
28    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
29    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
30      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
31    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
32    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
33      (was already the case for dissipation with mom_vecinv,
34       and also the case for grad.PhiHyd when staggered-timeStep)
35      This will allow to put dissipation out-off the AB time-stepping.
36     Unfortunately, affects truncation error. Update output of exp. that "fails"
37      (cg2d matching number) and leave the others for later: front_relax(10),
38      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
39      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
40    
41    checkpoint57o_post
42    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
43      (2) its ready to be documented during the 20050801 DocFest
44    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
45      for ideal_2D_oce and lab_sea on linux_ia32_g77
46    o set to #undef CTRL_SET_OLD_MAXCVARS_30
47      in global1x1_tot/code_seaice_adj to access indices 32, 33
48      (worth another tag)
49    
50    checkpoint57n_post
51    o adding precip control xx_precip 32
52    o adding swflux control xx_swflux 33
53    o Replacing 10 forcing penalty cost routines by 1 generic.
54    o Implementing partitioning in time-mean and variable adjustment
55      for atmos. state.
56    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
57    o in natl_box_adjoint:
58      * updated exp 1 to 10
59        (but does not have time-mean vs. variable split results yet)
60    o updated global1x1/*_seaice_adj/
61      to incorporate latest changes
62    o enable useSingleCpuIO for mdsio vector routines
63      (applies in particular to tapelev I/O)
64    o removed inefficient K-loop in all active_file*control*.F
65    
66    checkpoint57m_post
67    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
68      and advect_cs (use EXCH-2 and standard cs-32 grid files).
69    o pkg/exch2: filling of face-corner halo regions is optional
70      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
71    
72    checkpoint57l_post
73     tag before updating tutorials (pre-release-2)
74    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
75       for output and interpolation of input fields onto model grid)
76    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
77       Affects results of exp. rotating_tank ; update output.txt.
78    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
79          and taking the square quantity and/or using a fraction-weight field.
80    o fix aim_diagnostics_init.F mate numbers.
81    o add mnc output capability to diagnostics/diagstat and update
82      our cvsignore files for the ACSII output generated
83    
84    checkpoint57k_post
85    o lab_sea now uses diagnostics package and provides a suite of
86      new EXF diagnostics output.
87    
88    checkpoint57j_post
89    o exf
90      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
91        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
92        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
93      * extended diagnostics output
94        - now includes all EXF variables
95        - hs, hl moved to common block
96        - separate S/R for diagnostics, called after ctrl vector is added
97        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
98        - EXFqnet contains true Qnet (i.e. includes qsw)
99      * updated verif. lab_sea, global_with_exf
100      * Rearranging hflux (exf_mapfields -> exf_getforcing)
101        to ensure that diagnostics sees a true EXFqnet
102    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
103    o diagnostics pkg: change pointers so that 1 diagnostic can be used
104      several times with different frequencies.
105    o mnc-ify the thsice package as requested by Daniel Enderton
106      - the monitor--MNC output needs work
107      - many attributes need to be added (most are currently blank)
108    o mnc-ify theaim_v23 package as requested by Daniel Enderton
109      - many attributes need to be added (most are currently blank)
110    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
111    o add Sadourny like discretization to the 4th.O vorticity advection scheme
112    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
113      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
114         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
115    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
116     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
117    
118    checkpoint57i_post
119    o Diagnostics package was changed: diagnostic allocation is now deactivated
120      by setting an empty file name in the namelist (used to be by setting 0 frequency)
121    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
122      add 1rst Order upwind vertical Shear.
123    o add a quick fix for A/B checkpointing in OFFLINE mode
124    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
125      end-run around the C/Fortran linking horror in eesup/src/timers.F
126    o added pkg/runclock: allows user to terminate run based on wall clock
127    o added non-hydrostatic scaling parameter: nh_am2
128    o pkg/my82: futile attempt to make results compiler-independent by adding
129      some "_d 0", etc. no effect.
130    o for mnc output, fill the 'T' coordinate var with myTime and create a
131      separate 'iter' variable for iteration count
132    o pkg/diagnostics:
133      add new capability: output of Global/Regional & per-level statistics ;
134      tested against monitor output (including land & thSIce) on various exp.
135    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
136    
137    checkpoint57h_done
138      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
139      data.diagnostics, data.gchem, data.ptracers) is done.
140    
141    o pkg/diagnostics: prepare for Global/Regional statistics.
142      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
143    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
144      and rename it: DIFFERENT_MULTIPLE
145    
146    checkpoint57h_post
147    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
148    o pkg/diagnostics: change output frequency, now in seconds (instead
149      of Nb of iterations). This requires to change data.diagnostics.
150    checkpoint57h_pre
151    
152    o in mnc, let the user create the output dir if both mnc_outdir_date
153      and mnc_outdir_num are false
154    o add fflags() to pkg/diagnostics which allows one to specify, on a
155      per-file basis, the file precision [default behavior is unchanged]
156    o added diagnostics to pkg/kpp, including computation of mixed layer
157      depth based on a temperature/density criterion
158    o updated verification/natl_box to test the new pkg/kpp diagnostics
159    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
160    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
161    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
162      not mnc -- this mistake was found by JMC and is now corrected
163    
164    checkpoint57g_post
165    o add Adams-Bashforth 3rd Order time stepping:
166      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
167      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
168    checkpoint57g_pre
169    
170    o make lambda[Theta,Salt]ClimRelax spatially varying
171      (default remains spatially uniform constant based on tau)
172    o added new control variables
173      * init. uVel, vVel, etanN
174      * lambda[Theta,Salt]ClimRelax
175    o separate masks used for ctrl_pack/unpack 'from write_grid' output
176      (suggested by G. Forget)
177    
178    checkpoint57f_post
179    o add parameter "baseTime" = model base time = time at iteration zero
180      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
181      account for baseTime shift
182    o move Coriolis arrays from PARAMS.h to GRID.h
183    checkpoint57f_pre
184    
185    o mnc-ifying the seaice package
186    o introduced an alternative length scale calculation for use in the limiting
187      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
188    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
189    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
190      as well as grad(vort3).  Made it compatible with both approximate form
191      for the cubed sphere and full form of these gradients.  Added flag
192      useFullLeith to select between approximate and full form.  
193    o add "d0" in getcon.F to reduce differences between compilers/platforms
194      update output.txt of exp. fizhi-gridalt-hs
195    o change port_rand funtion to allow to set the seed.
196    o fix obscure MNC bug involving conversion between reals and integers
197      - it caused no problems with certain (eg. gcc, ifc) compilers but the
198        new version is now more standards-compliant
199    o adjoint-related modifications
200      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
201      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
202      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
203    
204    checkpoint57e_post
205    o Adding eddy stress controls a la Ferreira et al.
206    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
207    
208    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
209      update output.txt of exp. fizhi-gridalt-hs
210    o add more "Z" dimensions and associated coordinate vars to MNC
211    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
212    o parameter calendarDumps: when set, approximate months (30-31 days) and years
213      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
214      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
215      months and years.  Requires pkg/cal.
216    o diagnostics: add pickup functionality
217      - off by default for backwards compatibility
218      - current version only uses MDSIO -- MNC will be added
219    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
220    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
221    
222    checkpoint57d_post
223    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
224    o modify verification/ideal_2D_oce so that it tests the creation of mnc
225      output from the diagnostics package
226    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
227  o make genmake2 more portable by using ".$FS" instead of ".f" for more  o make genmake2 more portable by using ".$FS" instead of ".f" for more
