5      ==============================      ==============================
6    
7    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
8      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
9    o add brackets in multi-terms sum to get same truncation, independent of
10      the face number (manage to get exactly same value of gU,gV at the cs-edge)
11      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
12    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
13      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
14      a maximum grid-scale Reynolds number.  Also, changes all length calculations
15      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
16      Suggested values of viscosity parameters found in mom_calc_visc.
17      Many new viscosity diagnostics available.
18    
19    checkpoint57s_post
20    o Add clearing-house for viscosity calculations, mom_calc_visc and
21      correct numerous bugs in LeithD and Smagorinsky discretizations.  
22      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
23      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
24      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
25      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
26      The Strain-Tension form is now called with useStrainTensonVisc=.true.
27      ViscAhStrain and viscAhTension are now retired.
28    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
29    o In response to JMC's bug report, genmake2 now ignores any soft-links
30      that it finds in the *current* directory when searching for files.
31      Soft-links found in any other source directories will still work as
32      they did before.
33    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
34      a C routine to unlimit the stack size
35    o mnc-ify pkg/aim snapshot vars
36    o mnc-ify pkg/land as requested by Daniel
37    o various changes to mnc including:
38      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
39      - output can now be grouped so that all files within a group
40          change the ITER portion of their names in lock-step together
41      - can now read ("global") PER-FACE (in addition to PER-TILE) files
42          and works with both EXCH1 and EXCH2 (but needs more testing)
43      - writing works for all verification test cases w/ g77 on Linux
44    
45    checkpoint57r_post
46    o make MNC variable initialization happen earlier
47    o add diagnostics for (almost) each term of the momentum Eq.
48    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
49    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
50    o remove MINIMAL_TAVE_OUTPUT option ;
51      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
52    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
53      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
54    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
55    o add time-dependent SST, SSS control
56    o cost terms in ecco/ modularized (new cost_generic.F)
57    o cost_averages routines are modularized (new cost_averagesgeneric.F)
58    o new infrastructure for seaice model vs. obs misfits in seaice/
59      * driver from the_main_loop.F is seaice_cost_driver.F
60      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
61      * gradient check in Exp. 6a of natl_box_adjoint/
62    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
63      (see README file)
64    
65    checkpoint57q_post
66    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
67    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
68      - bug was reported by Jean-Michel and Ian Fenty
69    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
70      update exp. cpl_aim+ocn output.
71    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
72      Needed for high-res. runs with large global files
73      to be able to limit tapelev size
74    o Changed some tests for adjoint:
75      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
76      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
77      * global_ocean.90x40x15/ back to default 3-level checkpointing
78    o Modifications to enable scripted COMMON to MODULE conversion
79      * verification/OpenAD/code/ has necessary scripts and description;
80      * converts, compiles and runs successfully;
81    
82    checkpoint57p_post
83    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
84    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
85      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
86    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
87    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
88      (was already the case for dissipation with mom_vecinv,
89       and also the case for grad.PhiHyd when staggered-timeStep)
90      This will allow to put dissipation out-off the AB time-stepping.
91     Unfortunately, affects truncation error. Update output of exp. that "fails"
92      (cg2d matching number) and leave the others for later: front_relax(10),
93      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
94      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
95    
96    checkpoint57o_post
97    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
98      (2) its ready to be documented during the 20050801 DocFest
99    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
100      for ideal_2D_oce and lab_sea on linux_ia32_g77
101    o set to #undef CTRL_SET_OLD_MAXCVARS_30
102      in global1x1_tot/code_seaice_adj to access indices 32, 33
103      (worth another tag)
104    
105    checkpoint57n_post
106    o adding precip control xx_precip 32
107    o adding swflux control xx_swflux 33
108    o Replacing 10 forcing penalty cost routines by 1 generic.
109    o Implementing partitioning in time-mean and variable adjustment
110      for atmos. state.
111    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
112    o in natl_box_adjoint:
113      * updated exp 1 to 10
114        (but does not have time-mean vs. variable split results yet)
115    o updated global1x1/*_seaice_adj/
116      to incorporate latest changes
117    o enable useSingleCpuIO for mdsio vector routines
118      (applies in particular to tapelev I/O)
119    o removed inefficient K-loop in all active_file*control*.F
120    
121    checkpoint57m_post
122    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
123      and advect_cs (use EXCH-2 and standard cs-32 grid files).
124    o pkg/exch2: filling of face-corner halo regions is optional
125      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
126    
127    checkpoint57l_post
128     tag before updating tutorials (pre-release-2)
129    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
130       for output and interpolation of input fields onto model grid)
131    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
132       Affects results of exp. rotating_tank ; update output.txt.
133    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
134          and taking the square quantity and/or using a fraction-weight field.

142    
143    checkpoint57j_post
144    o exf
145      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
146        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
147        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
148      * extended diagnostics output
149        - now includes all EXF variables
150        - hs, hl moved to common block
151        - separate S/R for diagnostics, called after ctrl vector is added
152        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
153        - EXFqnet contains true Qnet (i.e. includes qsw)
154      * updated verif. lab_sea, global_with_exf
155      * Rearranging hflux (exf_mapfields -> exf_getforcing)
156        to ensure that diagnostics sees a true EXFqnet
157    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
158    o diagnostics pkg: change pointers so that 1 diagnostic can be used
159      several times with different frequencies.
160    o mnc-ify the thsice package as requested by Daniel Enderton
161      - the monitor--MNC output needs work
162      - many attributes need to be added (most are currently blank)
163    o mnc-ify theaim_v23 package as requested by Daniel Enderton

172    
173    checkpoint57i_post
174    o Diagnostics package was changed: diagnostic allocation is now deactivated
175      by setting an empty file name in the namelist (used to be by setting 0 frequency)
176    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
177      add 1rst Order upwind vertical Shear.
178    o add a quick fix for A/B checkpointing in OFFLINE mode
179    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
180      end-run around the C/Fortran linking horror in eesup/src/timers.F
181    o added pkg/runclock: allows user to terminate run based on wall clock
182    o added non-hydrostatic scaling parameter: nh_am2
183    o pkg/my82: futile attempt to make results compiler-independent by adding
184      some "_d 0", etc. no effect.
185    o for mnc output, fill the 'T' coordinate var with myTime and create a
186      separate 'iter' variable for iteration count
187    o pkg/diagnostics:
188      add new capability: output of Global/Regional & per-level statistics ;
189      tested against monitor output (including land & thSIce) on various exp.

196    o pkg/diagnostics: prepare for Global/Regional statistics.
197      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
198    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
199      and rename it: DIFFERENT_MULTIPLE
200    
201    checkpoint57h_post
202    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
203    o pkg/diagnostics: change output frequency, now in seconds (instead
204      of Nb of iterations). This requires to change data.diagnostics.
205    checkpoint57h_pre
206    
207    o in mnc, let the user create the output dir if both mnc_outdir_date
208      and mnc_outdir_num are false
209    o add fflags() to pkg/diagnostics which allows one to specify, on a
210      per-file basis, the file precision [default behavior is unchanged]
211    o added diagnostics to pkg/kpp, including computation of mixed layer
212      depth based on a temperature/density criterion
213    o updated verification/natl_box to test the new pkg/kpp diagnostics
214    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
215    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
216    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
217      not mnc -- this mistake was found by JMC and is now corrected
218    
219    checkpoint57g_post
220    o add Adams-Bashforth 3rd Order time stepping:
221      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
222      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
223    checkpoint57g_pre
224    
225    o make lambda[Theta,Salt]ClimRelax spatially varying
226      (default remains spatially uniform constant based on tau)
227    o added new control variables
228      * init. uVel, vVel, etanN
229      * lambda[Theta,Salt]ClimRelax
230    o separate masks used for ctrl_pack/unpack 'from write_grid' output
231      (suggested by G. Forget)
232    
233    checkpoint57f_post

244    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
245      as well as grad(vort3).  Made it compatible with both approximate form
246      for the cubed sphere and full form of these gradients.  Added flag
247      useFullLeith to select between approximate and full form.  
248    o add "d0" in getcon.F to reduce differences between compilers/platforms
249      update output.txt of exp. fizhi-gridalt-hs
250    o change port_rand funtion to allow to set the seed.
251    o fix obscure MNC bug involving conversion between reals and integers
252      - it caused no problems with certain (eg. gcc, ifc) compilers but the
253        new version is now more standards-compliant
254    o adjoint-related modifications
255      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
256      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33

268      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
269      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
270      months and years.  Requires pkg/cal.
271    o diagnostics: add pickup functionality
272      - off by default for backwards compatibility
273      - current version only uses MDSIO -- MNC will be added
274    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.

280      output from the diagnostics package
281    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
282    o make genmake2 more portable by using ".$FS" instead of ".f" for more
283      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
284    o add coordinate variables to the MNC output from the diagnostics package
285    o change MNC-flags default value: true when useMNC=TRUE
