5      ==============================      ==============================
6    
7    o cleanup our namelist syntax in verification:
8      - make it more F95 standards compliant (some work still needed)
9      - allows the vast majority of our tests to work with gfortran
10    o Non-Hydrostatic:
11     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
12     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
13    o Allow to apply AB on T,S rather than on AB(gT,gS):
14     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
15     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
16       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
17     - need a "clever" read_pickup to restart from the other AB formulation
18    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
19    o remove some unused variables (reduces number of compiler warnings)
20    o adjoint
21      * Disable useVariableViscosity for adjoint for time being
22        (there are a number of extensive recomputations)
23      * Initialize certain variables needed for adjoint
24    
25    checkpoint57w_post
26    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
27                 fix the singleCpuIO RS version of MDSWRITEFIELD
28       and add a WARNING if using globalFiles=T with multi-processors.
29    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
30      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
31    o tracer advection scheme:
32      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
33       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
34       was not very convenient).
35      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
36       (further tests needed for the implicit DST & Flux-Limiter schemes).
37    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
38      and sRef for convenience, handy, when you want to initialize
39      ptracers in a large domain with a constant non-zero value. Also,
40      untangle ptracers_init.F a little.
41    
42    checkpoint57v_post
43    o change dome exp. to use variable viscosity in side-drag terms.
44    o remove all the files from the cfc_offline test since they are now
45      incorporated into tutorial_cfc_offline which has been producing
46      identical results for a few days of testing
47    o add new parameter: sideDragFactor to enable half-slip-side BC
48      and change side-drag S/R to use viscosity from mom_calc_visc
49      (can switch back by setting sideDragFactor=0.); affects results at
50      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
51       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
52    o vorticity & strain are now computed without masking, to account for
53      no-slip-side BC in variable viscosity calculation ; mask is applied
54      anyway later on, before computing advection/coriolis terms.
55    o modify exp4 to test new obcs support for reading from external files
56      and for passive tracers
57    o fix behavior of ptracers_monitor when monitor output is written to a
58      netcdf-file; still not independent of monitor.F (writes in the same
59      file).
60    o change default value of tRef (put a uniform, meaningful value for ocean
61      & atmos) and initialize sRef (was missing, as Martin mentioned).
62    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
63      to be proportional to enstrophy dissipation length.  Thus,
64       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
65      This is now consistent with Smagorinsky and with the manual.
66    
67    checkpoint57u_post
68    o OBCS and PTRACERS: add open boundary support for passive tracers
69      - either use homogenous (pseudo) v.Neumann conditions or prescribe
70        OB-values from file; this is not different from the way theta and salinity
71        are treated
72      - however, Orlanski-radiation conditions are not supported, and the model
73        will stop if you use pTracers and Orlanski at the same time.
74      - beefed up the rountine obcs_external_fields_load: now only those open
75        boundary values are overwritten with values from files for which there
76        are really files, otherwise the OB-fields remain untouched. This makes
77        it possible to use different OBs at different ends of the domain (as
78        with EXF)
79    o reduce number of exch calls in shap_filt (s2).
80    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
81      truncation level) 4/5 MLAdjust test results (11&12 digits match).
82    
83    checkpoint57t_post
84    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
85    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
86      same truncation, independent of the face number: affects affects several
87      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
88    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
89      note that biharmonic viscosity + no-slip was not tested in any experiment.
90    o fix bug in non-linear free-surf side-drag ; generate new output for
91      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
92    o make mnc honor the writeBinaryPrec flag for most kinds of output
93    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
94    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
95      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
96    o add brackets in multi-terms sum to get same truncation, independent of
97      the face number (manage to get exactly same value of gU,gV at the cs-edge)
98      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
99    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
100      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
101      a maximum grid-scale Reynolds number.  Also, changes all length calculations
102      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
103      Suggested values of viscosity parameters found in mom_calc_visc.
104      Many new viscosity diagnostics available.
105    
106    checkpoint57s_post
107    o Add clearing-house for viscosity calculations, mom_calc_visc and
108      correct numerous bugs in LeithD and Smagorinsky discretizations.  
109      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
110      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
111      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
112      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
113      The Strain-Tension form is now called with useStrainTensonVisc=.true.
114      ViscAhStrain and viscAhTension are now retired.
115    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
116    o In response to JMC's bug report, genmake2 now ignores any soft-links
117      that it finds in the *current* directory when searching for files.
118      Soft-links found in any other source directories will still work as
119      they did before.
120    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
121      a C routine to unlimit the stack size
122    o mnc-ify pkg/aim snapshot vars
123    o mnc-ify pkg/land as requested by Daniel
124    o various changes to mnc including:
125      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
126      - output can now be grouped so that all files within a group
127          change the ITER portion of their names in lock-step together
128      - can now read ("global") PER-FACE (in addition to PER-TILE) files
129          and works with both EXCH1 and EXCH2 (but needs more testing)
130      - writing works for all verification test cases w/ g77 on Linux
131    
132    checkpoint57r_post
133    o make MNC variable initialization happen earlier
134    o add diagnostics for (almost) each term of the momentum Eq.
135    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
136    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
137    o remove MINIMAL_TAVE_OUTPUT option ;
138      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
139    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
140      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
141    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
142    o add time-dependent SST, SSS control
143    o cost terms in ecco/ modularized (new cost_generic.F)
144    o cost_averages routines are modularized (new cost_averagesgeneric.F)
145    o new infrastructure for seaice model vs. obs misfits in seaice/
146      * driver from the_main_loop.F is seaice_cost_driver.F
147      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
148      * gradient check in Exp. 6a of natl_box_adjoint/
149    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
150      (see README file)
151    
152    checkpoint57q_post
153    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
154    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
155      - bug was reported by Jean-Michel and Ian Fenty
156    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
157      update exp. cpl_aim+ocn output.
158    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
159      Needed for high-res. runs with large global files
160      to be able to limit tapelev size
161    o Changed some tests for adjoint:
162      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
163      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
164      * global_ocean.90x40x15/ back to default 3-level checkpointing
165    o Modifications to enable scripted COMMON to MODULE conversion
166      * verification/OpenAD/code/ has necessary scripts and description;
167      * converts, compiles and runs successfully;
168    
169    checkpoint57p_post
170    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
171    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
172      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
173    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
174    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
175      (was already the case for dissipation with mom_vecinv,
176       and also the case for grad.PhiHyd when staggered-timeStep)
177      This will allow to put dissipation out-off the AB time-stepping.
178     Unfortunately, affects truncation error. Update output of exp. that "fails"
179      (cg2d matching number) and leave the others for later: front_relax(10),
180      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
181      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
182    
183    checkpoint57o_post
184    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
185      (2) its ready to be documented during the 20050801 DocFest
186    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
187      for ideal_2D_oce and lab_sea on linux_ia32_g77
188    o set to #undef CTRL_SET_OLD_MAXCVARS_30
189      in global1x1_tot/code_seaice_adj to access indices 32, 33
190      (worth another tag)
191    
192    checkpoint57n_post
193    o adding precip control xx_precip 32
194    o adding swflux control xx_swflux 33
195    o Replacing 10 forcing penalty cost routines by 1 generic.
196    o Implementing partitioning in time-mean and variable adjustment
197      for atmos. state.
198    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
199    o in natl_box_adjoint:
200      * updated exp 1 to 10
201        (but does not have time-mean vs. variable split results yet)
202    o updated global1x1/*_seaice_adj/
203      to incorporate latest changes
204    o enable useSingleCpuIO for mdsio vector routines
205      (applies in particular to tapelev I/O)
206    o removed inefficient K-loop in all active_file*control*.F
207    
208    checkpoint57m_post
209    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
210      and advect_cs (use EXCH-2 and standard cs-32 grid files).
211    o pkg/exch2: filling of face-corner halo regions is optional
212      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
213    
214    checkpoint57l_post
215     tag before updating tutorials (pre-release-2)
216    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
217       for output and interpolation of input fields onto model grid)
218    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
219       Affects results of exp. rotating_tank ; update output.txt.
220    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
221          and taking the square quantity and/or using a fraction-weight field.
222    o fix aim_diagnostics_init.F mate numbers.
223    o add mnc output capability to diagnostics/diagstat and update
224      our cvsignore files for the ACSII output generated
225    
226    checkpoint57k_post
227    o lab_sea now uses diagnostics package and provides a suite of
228      new EXF diagnostics output.
229    
230    checkpoint57j_post
231    o exf
232      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
233        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
234        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
235      * extended diagnostics output
236        - now includes all EXF variables
237        - hs, hl moved to common block
238        - separate S/R for diagnostics, called after ctrl vector is added
239        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
240        - EXFqnet contains true Qnet (i.e. includes qsw)
241      * updated verif. lab_sea, global_with_exf
242      * Rearranging hflux (exf_mapfields -> exf_getforcing)
243        to ensure that diagnostics sees a true EXFqnet
244    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
245    o diagnostics pkg: change pointers so that 1 diagnostic can be used
246      several times with different frequencies.
247    o mnc-ify the thsice package as requested by Daniel Enderton
248      - the monitor--MNC output needs work
249      - many attributes need to be added (most are currently blank)
250    o mnc-ify theaim_v23 package as requested by Daniel Enderton
251      - many attributes need to be added (most are currently blank)
252    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
253    o add Sadourny like discretization to the 4th.O vorticity advection scheme
254    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
255      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
256         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
257    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
258     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
259    
260    checkpoint57i_post
261    o Diagnostics package was changed: diagnostic allocation is now deactivated
262      by setting an empty file name in the namelist (used to be by setting 0 frequency)
263    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
264      add 1rst Order upwind vertical Shear.
265    o add a quick fix for A/B checkpointing in OFFLINE mode
266    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
267      end-run around the C/Fortran linking horror in eesup/src/timers.F
268    o added pkg/runclock: allows user to terminate run based on wall clock
269    o added non-hydrostatic scaling parameter: nh_am2
270    o pkg/my82: futile attempt to make results compiler-independent by adding
271      some "_d 0", etc. no effect.
272    o for mnc output, fill the 'T' coordinate var with myTime and create a
273      separate 'iter' variable for iteration count
274    o pkg/diagnostics:
275      add new capability: output of Global/Regional & per-level statistics ;
276      tested against monitor output (including land & thSIce) on various exp.
277    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
278    
279    checkpoint57h_done
280      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
281      data.diagnostics, data.gchem, data.ptracers) is done.
282    
283    o pkg/diagnostics: prepare for Global/Regional statistics.
284      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
285    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
286      and rename it: DIFFERENT_MULTIPLE
287    
288    checkpoint57h_post
289    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
290    o pkg/diagnostics: change output frequency, now in seconds (instead
291      of Nb of iterations). This requires to change data.diagnostics.
292    checkpoint57h_pre
293    
294    o in mnc, let the user create the output dir if both mnc_outdir_date
295      and mnc_outdir_num are false
296    o add fflags() to pkg/diagnostics which allows one to specify, on a
297      per-file basis, the file precision [default behavior is unchanged]
298    o added diagnostics to pkg/kpp, including computation of mixed layer
299      depth based on a temperature/density criterion
300    o updated verification/natl_box to test the new pkg/kpp diagnostics
301    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
302    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
303    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
304      not mnc -- this mistake was found by JMC and is now corrected
305    
306    checkpoint57g_post
307    o add Adams-Bashforth 3rd Order time stepping:
308      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
309      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
310    checkpoint57g_pre
311    
312    o make lambda[Theta,Salt]ClimRelax spatially varying
313      (default remains spatially uniform constant based on tau)
314    o added new control variables
315      * init. uVel, vVel, etanN
316      * lambda[Theta,Salt]ClimRelax
317    o separate masks used for ctrl_pack/unpack 'from write_grid' output
318      (suggested by G. Forget)
319    
320    checkpoint57f_post
321    o add parameter "baseTime" = model base time = time at iteration zero
322      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
323      account for baseTime shift
324    o move Coriolis arrays from PARAMS.h to GRID.h
325    checkpoint57f_pre
326    
327    o mnc-ifying the seaice package
328    o introduced an alternative length scale calculation for use in the limiting
329      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
330    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
331    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
332      as well as grad(vort3).  Made it compatible with both approximate form
333      for the cubed sphere and full form of these gradients.  Added flag
334      useFullLeith to select between approximate and full form.  
335    o add "d0" in getcon.F to reduce differences between compilers/platforms
336      update output.txt of exp. fizhi-gridalt-hs
337    o change port_rand funtion to allow to set the seed.
338    o fix obscure MNC bug involving conversion between reals and integers
339      - it caused no problems with certain (eg. gcc, ifc) compilers but the
340        new version is now more standards-compliant
341    o adjoint-related modifications
342      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
343      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
344      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
345    
346    checkpoint57e_post
347    o Adding eddy stress controls a la Ferreira et al.
348    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
349    
350    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
351      update output.txt of exp. fizhi-gridalt-hs
352    o add more "Z" dimensions and associated coordinate vars to MNC
353    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
354    o parameter calendarDumps: when set, approximate months (30-31 days) and years
355      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
356      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
357      months and years.  Requires pkg/cal.
358    o diagnostics: add pickup functionality
359      - off by default for backwards compatibility
360      - current version only uses MDSIO -- MNC will be added
361    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
362    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
363    
364    checkpoint57d_post
365    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
366    o modify verification/ideal_2D_oce so that it tests the creation of mnc
367      output from the diagnostics package
368    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
369    o make genmake2 more portable by using ".$FS" instead of ".f" for more
370      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
371    o add coordinate variables to the MNC output from the diagnostics package
372    o change MNC-flags default value: true when useMNC=TRUE
373    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
374      the ability (off by default) to read the grid information using MNC
375    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
376    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
377    o do snap-shot diagnostics at the middle of the time-interval (instead of
378      at the end).
379    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
380      new test for AIM with thSIce + slab-ocean
381    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
382    o move state variable diagnostics to the beginning of the time step ;
383      (note: still needs some work specially for snap-shot diagnostics)
384      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
385    
386    checkpoint57c_post
387    o Change testing option (-ieee) to get closer agreement between g77 & ifort
388    o generate new output.txt files on faulks with g77 & the new -ieee option
389    checkpoint57c_pre
390    
391    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
392      update output.txt of exp. global_ocean.90x40x15
393    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
394      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
395    o add saltFlux(+File) forcing capability with periodicExternalForcing
396    o allow to use pkg diagnostics for GM-Redi & ThSIce output
397    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
398    o improvements for the MNC output from DIAGNOSTICS:
399      - correct handling of the unlimitied dimension
400      - all dims now have associated coordinate variables
401      - variables located at U, V, and Corner ("Z") points are now written
402        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
403        *all* data points are output
404    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
405    o added pkg/seaice/seaice_monitor.F
406    o mdsio_readfield.F can now read files visible only to master MPI process.
407    o pkg/seaice: some test code for ice-modified ocean stress
408    o exf_getffields interpolation defaults to bilinear for all scalar forcing
409      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
410      spurious negative numbers for precipitation and humidity.  Will cause
411      some small numerical differences for integrations using pkg/exf/exf_interp.F.
412    o pkg/ctrl/
413      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
414        May be enabled via doPackDiag
415      *  introduce z-scaling of
416         + gradient (doZscalePack) and
417         + control (doZscaleUnpack)
418    o pkg/mdsio/
419      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
420      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
421    
422    checkpoint57b_post
423    o simplify options in diagnostics_fill arguments (remove weird combinations)
424    o fix MNC coordinate variables so that they now contain per-face index
425      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
426      general, EXCH2 grids are only aligned to a "local" coordinate system
427    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
428    o Implement instantaneous output within pkg diagnostics:
429      setting a negative frequency in data.diagnostics produces
430     "snap-shot" output (as opposed to time-average if freq > 0)
431    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
432      NOTE: change ptracer diagnostics name: use 2 characters to work with
433            more than 9 tracers. Add also diagnostics of advect & diffus flux.
434    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
435      becomes the coordinate variable for the 'T' dimension
436    o add CF-style coordinate variables to MNC
437      - just a first cut:  numbers are meaningless on the cubesphere and
438        missing along the T axis but otherwise it works!
439    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
440    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
441    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
442      this is based directly on what the model compute, so that the content of
443      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
444    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
445    o clean up build options files for SunOS, in particular
446      - remove -traditional from xmakedepend
447      - change -xarch=v9 to -xarch=native for f77
448      - restore use of make (not gmake)
449      - add CC=gcc if using g77
450    o changes per discussion of AM, JMC, & EH3 today:
451      - move redundant "grid" variables out of "state" -- in preparation of
452        creating proper CF-style coordinate variables and in recognition
453        that any/all grid variables can be easily copied (eg. w/NCO) from
454        the grid files into any of the other NetCDF files
455      - *always* output grid variables with MDSIO (this will eventually be
456        changed)
457      - output MNC grid file if useMNC is true
458    o every instance of _END_MASTER() has been found and replaced with
459      _END_MASTER( myThid ) in order to satisfy certain picky Sun
460      preprocessors
461    o re-arrange diagnostics pkg initialisation:
462     - allow each package to extend the available diagnostics list
463     - add some checking and fix small problems (multi-threaded, ...)
464     - new S/R diagnostics_fill (replace fill_diagnostics):
465       look through the short list of active diag. (instead of the long list)
466       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
467    
468    checkpoint57a_post
469    o this set of changes restores TAMC compatibility
470      tested for global_ocean.90x40x15 adjoint on trough
471      (what a pain)
472    
473    checkpoint57a_pre
474    o some modifs in tools/build_options for sunos
475    o call ctrl_pack for ctrl at end for optimcycle=0
476    
477    checkpoint57
478    o add horizontal bi-harmonic viscosity for vertical velocity
479      - new parameter viscA4W (defaults to viscA4)
480      - affects only non-hydrostatic code
481      - to be done: no-slip lateral boundary conditions
482    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
483    o implement Implicit Vertical advection for pTracers
484    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
485      (implemented also for implicit vertical diffusion & advection)
486    o OBCS: extend application of tracer open boundary conditions
487      to a strip beyond the boundary of width Olx/Oly
488    o add call monitor to TAF set of required calls (flow directives)
489      and include in natl_box_adjoint
490    o untangle a few ifdefs related to cost, ctrl, autodiff
491      untangel a few ALLOW_ECCO_OPTIMIZATION
492    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
493      (theta2, salt2 in ecco_cost_weights)
494    
495    checkpoint56c_post
496    o OBCS as control variables
497      - update ctrl_ad_diff.list, obcs_ad_diff.list
498      - remove balance of obcs controls from default
499      - fix index bug nobcs in ctrl_init
500      - fix dummy fields filen in ctrl_pack
501      - add dummy weights for obcs
502    o lsopt: comment out fort.94 output
503    o optim:
504      - remove unnecessary header files
505      - adjusted namelists
506      - add xerbla.F to Makefile
507    o exf:
508      - multiple modifications of exf_check_range
509      - unit change in exf_init_runoff from [m/year] to [m/s]
510    o mdsio:
511      - i/o-vector change debugLevel from debLevA to debLevB
512    
513    checkpoint56b_post
514    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
515      is called from DO_THE_MODEL_IO
516      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
517      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
518      - clean up PTRACERS_WRITE_TIMEAVE a little
519    o add another verification experiment that tests both the cfc-pkg and
520      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
521      reactive tendencies treated inline with regular timestepping
522    o testreport previously did a lousy job of comparing small numbers, so
523      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
524      implemented in the little c-progam tmp_cmpnum.c which is embedded in
525      testreport.
526    o ptracers_monitor: bug fix for MPI
527    
528    checkpoint56a_post
529    o GCHEM: finish reorganizating the package
530      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
531        (introduces another 3D-array for each passive tracer, but only if
532        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
533        gchemTendency is not needed because the timestep is done separately)
534      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
535      - GCHEM is now---more or less cleanly---separate from PTRACERS
536      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
537        so clear to me how that should be done in a general way.
538    o CFC: improve formatting of output in CFC_ATMOS
539    o PTRACERS:
540      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
541        that ALL experiments with ptracers enable can be checked. This makes
542        GCHEM_MONITOR obsolete.
543      - include a runtime parameter PTRACERS_monitorFreq that defaults to
544        monitorFreq
545      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
546    o add PTRACERS (PTR0[1-5]) to testreport output
547    o exf_check_range:
548      * default changed to .TRUE.
549      * will check values for niter0 if debLevA, every timestep if debLevB
550      * STOP in exf_check_range if 'out of range'
551      * range chosen generous to allow for potential extema
552      TBD: a version with stricter range
553           permitted range would be runtime parameters
554    o GMredi:
555      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
556      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
557      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
558    o GCHEM:
559      - move call to GCHEM_FORCING_SEP, so that it is now called before
560        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
561      - introduced a useGCHEM runtime flag and applied it everywhere.
562      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
563        this flag is now only visible within GCHEM-pkg routines.
564      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
565        be replaced by a 3D array that is computed before thermodynamics; for
566        this, the tracer ID iTracer had to be included into the parameter list
567        of ptracers_forcing
568      - set up forward_step to call gchem_forcing, that will replace
569        gchem_forcing_int in ptracers_forcing
570      - cleaning up
571    o small cleaning of exch2: remove files that are also in eesupp/src
572    
573    checkpoint56
574    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
575    o mnc: cleanup "full" files--fixes out-of-memory problem
576    o ECCO-GODAE
577      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
578      * fully merged and updated from SIO code
579        windstress sign change affects
580        - exf_inscal_[u/v]stress
581        - sign of xx_tau[u/v] adjustments
582        - signs in cost_scat
583      * ctrl_get_gen: avoid update of tau[u/v] for first few days
584      * natl_box_adjoint updated and compressed
585      * 2-level checkpoint switch added
586        (tested in EXP. 1 of natl_box_adjoint)
587      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
588    o SVD
589      * first complete, non-hacked version for SVD calculations
590      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
591        performed via direct access files admtlm_vector.it????
592        (via ctrl_[un]pack)
593      * optimcycle is used for ARPACK iteration counter
594        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
595      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
596        and add linear transforms where necessary
597      * controls are initial/final SST, SSS (can be extended; need to check
598        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
599    o mdsio: filename info to both stderr, stdout
600    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
601      from sign change
602    
603    checkpoint55j_post
604    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
605      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
606    o add consistent build directories and .cvsignore files to verification
607    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
608    o make all subroutines 30 or less characters in length for certain older
609      compilers to work (a thorough search only turns up two routines in
610      pkg/ptracers)
611    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
612      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
613    
614    checkpoint55i_post
615    o change arrays for total vertical diffusivity (2.D if explicit,
616      3.D if implicit) ; each ptracer uses its own background value.
617    o added mnc/NetCDF output capability to ocn_compon_interf
618      - added bits to verification/cpl_aim+ocn so that it can run on
619        ITRDA and other clusters without the mpirun "-wd" option
620    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
621      configuration
622    o give MNC the ability to create additional files rather than
623      exceeding a specified file size limit "MNC_MAX_FILESIZE"
624      - the default is just less than 2GB which is a practical limit
625        on many systems
626    o Compute the non-local term using either KPP vertical diffusivity (=default)
627       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
628    
629    checkpoint55h_post
630    o add verification test "vermix"
631    o remove all the *_ioinc flags and replace with the single global
632      outputTypesInclusive flag
633    o allow to set a vertical profile of vertical diffusivity for T & S
634    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
635    o useMNC moved from data.mnc to data.pkg
636    
637    checkpoint55g_post
638    o Renaming carbon AD experiments to comply with testreport conventions
639    o Updating adjoint of Held-Suarez hs94.1x64x5
640    o Fixing directives for non-ECCO forward_step, after ECCO directives
641      have been fixed to avoid recomp. of do_oceanic_phys
642      Works well for global_ocean.90x40x15,
643      but recomp. issue remains for carbon
644    o Updating adjoint output for natl_box_adjoint after
645      pkg/ecco has been modified (see taga c55d_post)
646    
647    checkpoint55f_post
648    o rename to timeave_init_fixed
649    
650    checkpoint55e_post
651    o some delicate re-shuffle of store directives to avoid one
652      extra call of do_oceanic_physics
653      affects ecco_the_main_loop.F, do_oceanic_physics.F
654      checkpoint_lev1_directives.h
655    o NB: this may break global_ocean adjoint temporarily,
656      but it is clear how to fix it. Will do later, need this now.
657    
658    checkpoint55d_post
659    o ECCO specific cost function terms (up-to-date with 1x1 runs)
660    o ecco_cost_weights is modified to 1x1 runs
661    o modifs to allow observations to be read in as
662      single file or yearly files
663    o enable to read exf forcing fields as either
664      single file or yearly files (flag useExfYearlyFields)
665    checkpoint55d_pre
666    
667    o switch between 2-level and 3-level checkpointing
668    o add ability of MNC to write local and "partial" (eg. 2D slices where
669      the full 3D field is never actually stored) arrays to NetCDF files
670      with the correct (that is, the complete multi-dimensional) set of
671      array indicies
672      - used in mom_vecinv() to write the diagFreq output
673      - tested (demonstrated) in verification/aim.5l_cs
674    o further mnc-ification
675      - add verification/lab_sea to the list with mnc setups
676      - fix undefined mnc v-names in cd_code
677      - add kpp to mnc output (both snapshot and timeave)
678    o non-hydrostatic code
679      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
680        in calc_gw.F
681      - defaults to viscAh
682      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
683        friction or Leith) in non-hydrostatic mode, as long as there is
684        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
685    o pkg/cost
686      extend simple cost functions to treat time mean quantities
687      (T,U,V) via cost_accumulate_state from cost_tile
688    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
689        be 2 times larger than the minimum size the advection scheme requires.
690        now get a perfect conservation of salt in advect_cs test-exp (updated)
691    o GGL90 (Gaspar's TKE mixed layer)
692      - add horizontal diffusion of TKE, requires exchanges in
693        do_fields_blocking_exchanges, horizontal diffusivity is zero by
694        default. In OPA there is no horizontal diffusion of TKE but the
695        mixing coefficients are computed from a horizontal average of TKE of
696        6 points or so. I think that diffusion has a little more physical
697        justification.
698      - clean up ggl90_calc in the hope of reducing memory usage (this hope
699        was in vain)
700      - mask tke-variable in ggl90_init
701    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
702    o fix biharmonic diffusion on CS-grid.
703    o more obcs stuff
704      - added obcs_external_fields_load as an alternative to the EXF-pkg option
705        for reading boundary values. This routine is called from
706        obcs_prescribe_read
707      - updated obcs_check
708      - changed sponge layer relaxation parameter units for days to seconds
709      - turned off sponge layer by default
710      - changed argument list of OBCS_CALC to myTime+deltaTclock
711      - fixed about 35 bugs in obcs_external_fields_load
712    
713    checkpoint55c_post
714    o obcs stuff
715      - new runtime flags useOBCSprescribe, useOBCSbalance
716      - re-arranged obcs_calc
717      - moved exf_getobcs to obcs_prescibe_read
718        obcs_prescibe_read is called after ORLANSKI stuff
719        and independent of it (executable can contain all).
720      - updated obcs_check
721      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
722        These may be necessary only if tangential velocities are
723        prescribed at OB, not sure, needs testing.
724    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
725      which simplifies the calls and passes the ifc check-bounds test
726    
727    checkpoint55b_post
728    o add a 2D scalar, Z location, exchange_2 routine.
729    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
730      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
731      affects advect_cs results (for the wrong reason): update output.txt
732    o use a more standard discretization for biharmonic viscosity ;
733     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
734      affects results of dome set-up: update output.txt
735    o fix gad_advection.F (CubedSphere part), back to version 1.23
736    o fix bug in mom_vi_del2uv.F (CubedSphere part).
737    
738    checkpoint55a_post
739    o merged code to
740      * prescribe/read time-dependent open boundaries
741        (works in conjunction with exf, cal)
742      * sponge layer code for open boundaries
743      * each boundary N/S/E/W now has its own CPP option
744        (healthy for the adjoint)
745    
746    checkpoint55
747    o up-to-date adjoint of previous breaks
748      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
749      - global_ocean_ebm: adjoint still needs fix (TLM ok)
750      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
751      - carbon: * remove tr1-related adjoint verification
752                * add ptracer as control variable
753    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
754      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
755    
756    checkpoint54f_post
757    o in verification/carbin/ remove experiment related to
758      ALLOW_PASSIVE_TRACER (array tr1 etc)
759      code_ad/ input_ad/ results_ad
760    
761    o add two new packages
762      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
763        + subject to optimization (memory)
764      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
765        + subject to reordering (many GOTOs in the original code)
766        + so far opps is called for every (i,j) point, and then operates in
767          the vertical; one may want to reorder the scheme in order operate in
768          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
769          fields)
770    o overhaul of IO so that we now have flags for MDSIO and/or MNC
771      - all verification tests compile and run with linux_ia32_g77
772      - defaults are compatible with current input files--nothing
773        should change if you were not previously using MNC
774      - MNC output has been added in numerous places (eg. timeave)
775        but there are still a few writes not yet do-able with MNC
776        (this is in progress)
777      - flags now allow for either/or/both use of MDSIO and MNC and
778        documentation will soon follow
779      - numerous small formatting cleanups for ProTeX
780    o add version info (via BUILD_INFO.h) to MNC and stdout
781    
782    checkpoint54e_post
783    o add two new packages
784      - pp81 (Packanowski and Philander, 1981), Richardson number and
785        stratification dependent mixing
786      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
787      - these scheme operate in a similar manner as KPP (without ghat, of
788        course), however there is only one diffusivity that is used for both
789        temperature and salinity (and passive tracers)ç
790    o add offline package
791    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
792      provided by Stephanie Dutkiewicz
793    o genmake2: add ability to search for C compilers and cleanup test output
794      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
795    
796    checkpoint54d_post
797    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
798    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
799      leading to additional shift by 5 days each year of integration
800       (i.e. leading to considerable offset over the years)
801    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
802    o start with no AB and no initial filtering (staggerTimeStep):
803      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
804    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
805      (external loading & cpl import/export stay in forward_step.F)
806    o update coupling interface to work with new staggerTimeStep
807    o change MDSIO ptracers_pickup.
808    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
809    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
810    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
811    
812    checkpoint54c_post
813    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
814      this affects (truncation error) output.txt of test-exp:
815       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
816    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
817    o change Qnet to always be the net heat flux, (+upward).
818      affects (truncation error) output of natl_box exp.: updated
819    o define the max number of passive tracers in PTRACERS_SIZE.h
820    o start to test mnc routinely in exp0
821    o add sea-ice loading (sIceLoad) as a new forcing field.
822    
823    checkpoint54b_post
824    o add testreport "-j JOBS" option for parallel builds (tested and pretty
825       impressive on Altix and Opteron systems)
826    o diagnostics can now write NetCDF files through the mnc package
827    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
828    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
829    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
830      affects (truncation error) output of lab_sea & natl_box exp.: updated
831    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
832    
833    checkpoint54a_post
834    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
835    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
836    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
837    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
838      + internal_wave (shift in writing cg2d_ini_res)
839    checkpoint54a_pre
840    
841    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
842      - modified verification/lab_sea and natl_box_adjoint accordingly
843    
844    checkpoint54
845    checkpoint53g_post
846    o prepare splitting of thermodynamics: store convect.counter in common block
847    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
848      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
849    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
850    o new parameter "nShapS": allow to treat differently S from T (nShapT)
851    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
852    o restore adjointability
853    
854    checkpoint53f_post
855    o modifications that affect AIM experiment results (update output.txt):
856      - no advection of S at top interface Nr (pkg/generic_advdiff)
857      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
858    o AIM pkg:
859      - include stability function into surf.Flux derivative relative to Tsurf
860      - calculate clear-sky radiation & surface temp. change (for diagnostics)
861    
862    checkpoint53e_post
863    o merged cylindrical coord configuration
864    o added rotating_tank experiment
865    checkpoint53e_pre
866    
867    checkpoint53d_post
868    o faulks upgraded: re-generate output.txt that have changed:
869       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
870    o Added Bryan and Lewis, 1979, vertical diffusivity profile
871    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
872    o added Sadourny discretization of Coriolis
873      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
874      - re-enabled use of omega3 (useAbsVorticity)
875    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
876      vector-invariant equations
877      - note: does *NOT* yet use same variable visc. for no-slip BC's.
878    o recoded the lateral boundary conditions for non-hydrostatic w, this time
879      hopefully without new bugs
880      - still to do: biharmonic friction for non-hydrostatic w
881    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
882    o regenerated output for global_ocean_ebm (using -ieee)
883    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
884      of mom_common/
885      - simple re-arrangement of instructions within computing loop
886    checkpoint53d_pre
887    
888    checkpoint53c_post
889    o new version of coupler for AIM+thSIce and Ocean models
890     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
891     - land: change Evaporation of snow
892     - aim with thSIce: fix bug in snow-precip.
893    o changes to calc_gw.F
894     - bug fix for w^2 term near the bottom boundary
895     - (hopefully) improve the lateral slip boundary condtions for use with
896        partial/looped cells
897      - because the bug fix changes two verification experiments anyway (exp5
898        and plume on slope), change the lateral boundary condition from half slip
899        to the value of no_slip_sides
900    o ebm package wasnt quite up to the parallel task. Fixed that.
901    o Adjoint of EBM package + verification
902      * TLM OK
903      * ADM not sufficient accuracy yet (needs further testing)
904    
905    checkpoint53b_post
906    o Commiting new energy balance model to repository
907      * package is pkg/ebm
908      * verif. is verification/global_ocean_ebm
909      * references are in ebm_driver.F
910    C      * X. Wang, P. Stone and J. Marotzke, 1999:
911    C        Global thermohaline circulation. Part I:
912    C        Sensitivity to atmospheric moisture transport.
913    C        J. Climate 12(1), 71-82
914    C      * X. Wang, P. Stone and J. Marotzke, 1999:
915    C        Global thermohaline circulation. Part II:
916    C        Sensitivity with interactive transport.
917    C        J. Climate 12(1), 83-91
918    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
919    C        Destabilization of the thermohaline circulation
920    C        by atmospheric eddy transports.
921    C        J. Climate 7(12), 1870-1882
922    o Will need long integration testing.
923    checkpoint53b_pre
924    
925    o created pkg/mom_common in preparation for variable viscosity code
926    o renamed and split ini_mnc_io
927    o pkg/land: only liquid water can diffuse or run-off
928    o AIM using land: soil wetness availability account for snow
929    o added printMapIncludesZeros to EEPARMS namelist
930    
931    checkpoint53a_post
932    o restore TAMC compatiility for exf_constants.h
933      (no usage of _d in .h)
934    o Additional storing in KPP in an attempt to fix
935      TAMC problem with adjoint of KPP code.
936      (no success...)
937      Identical code works fine with TAF.
938    o Fixed verification/natl_box_adjoint experiments.
939      Initial conditions for Experiments 4 and 5 are now
940      set to "SEAICE_initialHEFF=0", which is more reasonable,
941      and hence gives results closer to that of Experiment 2.
942      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
943    
944    checkpoint53
945    o stable checkpoint with up to date adjoint
946      TLM tests only run for 1st grdchk at the moment. Its unclear if
947      this is a code problem or a problem with resetting code for g_
948      variables that is being autogenerated wrong.
949      Otherwise:
950       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
951       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
952         are both still in chaos following their security messes.
953    
954    checkpoint52n_post
955    o various build (mostly genmake2) changes including:
956      - ability to build/run more easily within Cygwin and MacOS X
957      - more complicated Makefiles with a stronger dependence on Gnu Make
958    o pkg/seaice modifications
959      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
960        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
961        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
962      - changed proxy for geostrophic velocity and updated
963        verification/lab_sea/results/* accordingly
964      - removed ADI dynamic solver from pkg/seaice
965      - replaced all occurrences of 1/CSTICE or 1/CSUICE
966        they caused a segmentation fault under certain circumstances
967      - removed unused field WATR
968    o bug fix in exf-package:
969      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
970         now reflect that.
971    o small fixes in the cal-package:
972      - set reference date to first of January for the 'model'-calendar
973      - failing of cal_CheckDate in cal_FullDate now actually results in a
974        warning
975    o small modifications in exf-package to increase flexibility:
976      - change climtempfreeze from a constant to a runtime parameter that
977        is specified in data.exf_clim (default = -1.9)
978      - introduce runtime parameter windstressmax (default = 2.0) that is
979        specified in data.exf
980    o fix in pkg/thsice:
981      - update Evap (Tsf changes) to be consistent with Latent heat flux
982      - maintain snow precipitation unchanged (even if Tsf >=0).
983     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
984    
985    checkpoint52m_post
986    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
987      this does not change any of the results, because myIter=0 in swfrac always
988      lead to jwtype=2 (the default anyway), but the call makes little sense
989      as a default
990    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
991    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
992      atmospheric model (AIM) to use it ; add a "slab ocean" component.
993    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
994    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
995    o extending useSingleCpuIO option to work with new exch2 I/O format
996      - old-style, missing-tile I/O is still accessible by defining CPP
997        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
998    o monitor package can write to NetCDF files and/or STDOUT
999    o fix re-definition bug in MNC_GRID_INIT_ALL()
1000    o doc/api_reference added
1001      - a framework for building an API Reference Manual using all
1002        the "protex" comments embedded in the code
1003      - see pkg/generic_advdiff, pkg/mnc for examples
1004    o MNC:
1005      - make myThid the last argument for all subroutines
1006      - new default for the grid files: NO halos
1007      - add useMNC and other run-time flags
1008      - separate per-file-group handling of the unlimited dimension
1009      - early initialization of MNC w/ flags read at the eeboot stage
1010        and lookup tables set in initialize_fixed
1011      - write all MNC output to a freshly-created directory
1012    o thermodynamics sea-ice (thsice) is now tested with testreport.
1013    o test exp. advect_cs: use the standard cs32 grid ; update output.
1014    o Added functionality to grdchk:
1015      pick global i,j,k position (or nearest wet) where to perform check.
1016    
1017    checkpoint52l_post
1018    o new land formulation:
1019      a) use ground enthalpy as prognostic variable to ensure exact
1020         energy conservation.
1021      b) account for water temperature and for latent heat of freezing
1022         in all processes (rain, run-off, ground storage)
1023      c) compute surface and ground temperature implicitly.
1024    o aim_v23 modification for new land model:
1025      a) Treat separately land / ocean / sea-ice surface fluxes
1026         to allow implicit computation of land & sea-ice surface temp.
1027      b) add snow precipitation.
1028    checkpoint52l_pre
1029    
1030    o fix problem (when 1 tile is empty) in min/max monitor.
1031    o fix bug in timeAve (u,vZetatave in common block)
1032    o no restoring terms under ice for pkg/seaice
1033    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1034    o bug fix for pkg/seaice pickups
1035    o change MNC call locations and add coordinate attributes
1036    o mask vorticity at the corner ; affects global_ocean.cs output
1037    o fix ini_curvilinear_grid ; test CS experiments with mpi
1038    o aim.5l_cs: modify sea-ice fraction input file ; update output
1039    o exf: Adding simple range check routine for exf fields after read
1040    
1041    checkpoint52k_post
1042    o removed top-level directory "diags"
1043      - we migrated these functions to pkg/timeave a long time ago
1044    o fixed bug introduced in pkg/monitor
1045    o accuracy ctrlprec = 32 insuffient for gradient checks using
1046      averaged fields (I/O via cost_averages)
1047      -> use ctrl.h in active_file*.F to control I/O precision.
1048    o paramter list of CALL ADTHE_MAIN_LOOP
1049    o added initial do_the_model_io to ecco
1050    o set all ...Freq to zero after cost_final
1051      taveFreq, dumpFreq, pChkptFreq
1052    o MAIN and ECCO differentiability restored
1053    
1054    checkpoint52j_post
1055    o fix nchklev in tamc.h for global_ocean...
1056    o Bringing flow and store directives up-to-date
1057    o Really weird thing!
1058      call do_the_model_io from the_main_loop with parameters
1059      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1060      TAF places a faulty re-call of initialise_varia
1061      after cost_final call which should not be there!
1062    checkpoint52j_pre
1063    
1064    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1065      error messages
1066    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1067    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1068      debug output
1069    o modfied mdsio_writefield.F to handle non-global files under exch2
1070    o update AIM Cubed-Sphere exp (aim.5l_cs):
1071      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1072    o update AIM Equatorial Channel exp:
1073      use standard aim_v23 pkg and change the SST fields to be more realistic.
1074    o globalFile now works with exch2
1075    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1076      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1077    o limit timeave output for hi-res integrations
1078    
1079    checkpoint52i_post
1080    o removed CPP_EEOPTIONS.h from verification/*/code
1081    o updated the tiling for global_ocean_pressure
1082    checkpoint52i_pre
1083    
1084    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1085      the old pkg/aim).
1086    
1087    checkpoint52h_pre
1088    o shortened offending lines in exch2_send_rx?.template
1089    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1090    o genmake2: add build & execute test for NetCDF code
1091    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1092      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1093    o added useSingleCPUIO flag to monitor.F and mon_out.F
1094    o added temporary hack for sea-ice dynamics on the cube:
1095      metric terms are ignored and it is assumed that
1096      there is no sea-ice on cube faces 1, 2, 4, and 5.
1097    
1098    checkpoint52f_post
1099    o added exch2 cube routines to pkg/exch2
1100    o modified hs94.cs-32x32x5 to use it
1101    o added new grid files to hs94.cs-32x32x5
1102    checkpoint52f_pre
1103    
1104    checkpoint52e_post
1105    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1106      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1107    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1108      to work with implicit vertical advection and AB ;
1109    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1110    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1111     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1112    checkpoint52e_pre
1113    
1114    o fix bug in impldiff when Nr=1 or Nr=2.
1115    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1116    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1117    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1118      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1119    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1120    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1121    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1122    
1123    checkpoint52d_post
1124    o re-tiled many expts to allow comparison in multi-processor mode
1125      - updated output accordingly
1126      - changed hs94.128x64x5 to use intial T from file rather than use the
1127        random number generator
1128    o add infrastructure in model routines for fizhi and gridalt packages
1129    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1130    o changes to permit hi-res, cubed-sphere, configuration
1131      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1132      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1133      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1134        of surface winds for the cube
1135      (A verification experiment, based on global_ocean.cs32x15, but with
1136       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1137       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1138       complete with example surface forcing files and matlab scripts to look
1139       at the output and compare it with that of global_ocean.cs32x15.)
1140    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1141       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1142       to conform to the common rule.
1143    o check-in the first version of the coupler + interfaces for multi-components
1144       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1145       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1146       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1147       - ocean and atmos. share the same horizontal grid (no interpolation).
1148       - exchanges between component and coupler is done in forward_step
1149    o new verification experiment, cpl_aim+ocn:
1150       coupled ocean - AIM atmosphere on cs32 grid.
1151    
1152    checkpoint52d_pre
1153    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1154    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1155    
1156    checkpoint52c_post
1157    o Fixing OPTIONS files for use of exf:
1158      - ALLOW_ECCO not needed
1159      - ECCO_CPPOPTIONS.h should not be included from
1160        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1161        as has been the case in the past
1162      - All cal/exf related options are currently set in
1163        single header file. Should remain so until we
1164        agree on a consistent new policy.
1165    o Removed all CPP options for cal package.
1166      cal has no more CPP options.
1167    o modified STOREs in GAD_ADVECTION
1168    o corrected key comp. for passkey
1169    
1170    checkpoint52b_post
1171    o new version: "thsice" of thermodynamic sea-ice pkg:
1172     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1173     - modify fluxes but do not change theta directly;
1174     - light cleaning of bulk_force pkg (still needed with thsice).
1175     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1176       + output_thsice.txt to test thsice & bulk_force pkgs.
1177    o put back grid & coriolis monitor output.
1178    checkpoint52b_pre
1179    
1180    o call "do_the_model_io" at the beginning (=> dump initial state)
1181    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1182    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1183      (need info on NUMBER_OF_PTRACERS)
1184    o missing PTRACERS headers in some routines
1185    o default tamc.h in pkg/autodiff supposed to crash
1186      to ensure proper customization
1187    
1188    checkpoint52a_post
1189    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1190      - moved surfaceTendencyTice from pkg/seaice to main code
1191      - subroutine FREEZE_SURFACE now limits only surface temperature
1192        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1193        => new output.txt for global_ocean.cs32x15 & global_with_exf
1194      - keep the old version of FREEZE for backward compatibility;
1195        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1196      - corresponding modifs for TAF directives
1197    o added surface flux output variables to TIMEAVE_STATVARS

1201      but no warning issued by TAF
1202    
1203    checkpoint52a_pre
1204    o some bug fixes for #undef REAL4_IS_SLOW
1205    
1206    checkpoint52 = ecco_c52_e35
1207    o after testing adjoints of checkpoint51u_post
1208    
1209    checkpoint51u_post
1210    o this is the post-merge tag of the ecco-branch
1211      (needs another clean checkout and re-testing)
1212    o various natl_box_adjoint configs and results
1213      but no input fields
1214    o obcs adjoint not yet merged!
1215    o adding ECCO global 1x1 and 2x2 degree configs
1216    o updated/extended some store directives for seaice
1217    o pkg/ecco now containes ecco-specific part of cost function
1218    o top level routines the_main_loop, forward_step
1219      supersede those in model/src/
1220      previous input data.cost now in data.ecco
1221      (new namelist ecco_cost_nml)
1222    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1223    
1224    checkpoint51t_post
1225    o this is the pre-merge tag of the ecco-branch
1226    
1227    checkpoint51s_post
1228    o cleanup: removed various obsolete #define-s
1229    o pkg/grdchk
1230      - renamed 'ph-grd 3' to 'grad-res'
1231      - merged from ecco-branch
1232        (remaining bug fixes for obcs gradient checks)
1233      - additional high-precision output for testreport
1234        (grep for 'precision_grdchk_result')
1235    
1236    checkpoint51r_post
1237    o cleaned up or removed CPP_OPTIONS.h files
1238    o updated results for some of the tests to reflect the new
1239      optfiles (-ieee: -O0 instead of -O3)
1240    
1241    checkpoint51q_post
1242    o cd_code:
1243      - moved cd_scheme.F -> cd_code_scheme.F
1244      - separate read_checkpoint from cd_code_ini_vars.F
1245      - separated cd_code part from write_checkpoint
1246      - updated AD_SOURCE, generated .flow
1247      - added CD_CODE_VARS.h to the_main_loop

1250      - pack/unpack now optional and decoupled from
1251        xx_/adxx_ I/O
1252      - ctrl_pack/unpack cleaned
1253        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1254      - confined inclusion of AD_CONFIG.h to where necessary.
1255    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1256    
1257    checkpoint51p_post
1258    o create initial cd_code package
1259      - WARNING: the initialization of fields within packages
1260        is broken because INI_FIELDS (where READ_CHECKPOINT is
1261        called) is called *before* PACKAGES_INIT_VARIABLES.
1262        This seems to be backwards since
1263        1) its important to initially zero the entire field including
1264           the "halo" region
1265        2) zeroing needs to be done *before* reading pickup info
1266           and the pickup call might or might not happen in any
1267           particular run
1268      - this needs an overhaul for R2
1269    o cleanup verification/*/code/GMREDI_OPTIONS.h

1304      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1305      - subroutine FREEZE now limits only surface temperature
1306        (this means new output.txt for global_ocean.90x40x15,
1307         global_ocean.cs32x15, and global_with_exf)
1308    o added surface flux output variables to TIMEAVE_STATVARS

1478    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1479    o AIM: use true log-P extrapolation for near surface temp (= as in
1480        F.Molteni paper) ; update aim.5l_cs output.
1481    o New variable in PARM03 for more flexible pickups
1482    o somewhat cleaned package initialisation sequence for
1483      ctrl/ cost/ ecco/ in packages_... routines
1484    
1485    checkpoint50g_post

1511     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1512       nearly a copy of kpp_transport_s
1513     - there is no analogue to SurfaceTendencyS, so I have to use
1514       gPtr(of the surface layer) instead
1515    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1516    checkpoint50e_pre

1528    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1529    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1530    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1531    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1532    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1533    
1534    checkpoint50c_pre
1535    Merging from release1_p13:
1536    o bug fix for pkg/seaice dynamic solver
1537    o Added SEAICE_initialHEFF to pkg/seaice
1538    
1539    checkpoint50b_post
1540    o store u*,v* in gU,V instead of in guNm1,gvNm1
1541    o in order to put the momForcing out of the Adams-Bashforth:
1542      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1543      to timestep.F
1544    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1545    o re-generate output for highly sensitive test-exp:
1546       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1547    
1548    checkpoint50b_pre
1549    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1550    o corrected CPP option mismatch in exf_Bulk... functions for case
1551      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1552    
1553    checkpoint50a_post
1554    o Bug fix for merging between c50 and KPP.
1555      ikey was passed from thermodynamics to kpp_calc via
1556      common block rather than being recomputed in kpp_calc,
1557      in contradiction with new key itdkey.
1558      New key ikppkey created, and tamc.h headers updated.
1559    
1560    checkpoint50
1561    - 2nd step of merge with ecco-branch:
1562      merge changes in ecco-branch back into main trunk
1563    - bug fix in find_alpha
1564    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1565    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1566    - merged some sliced AD support routines
1567    
1568    checkpoint49
1569    merged from ecco-branch:
1570    o exf:
1571      - Enable initialisation of forcing fields to constant
1572        (runtime) values.
1573      - in exf_getffields.F
1574        Reduce i-/j-loop to interior domain, discarding overlaps.
1575        That also fixes wrong TAF-key computations for key_1, key_2
1576        with bulf formulae.
1577      - exf_init.F modify #ifdef for exf_init_evap
1578      - exf_getffieldrec.F, ctrl_getrec.F
1579        The following INT-usages are not safe:
1580          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1581          fldcount = int(fldsecs/fldperiod) + 1
1582        and were modified.
1583    o autodiff: checkpoint_lev...
1584      - updated storing for bulk formulae (some arrays were missing)
1585      - added state for seaice package
1586      - synchronized with main branch
1587    o DIVA:
1588      Modif.s in
1589      - the_main_loop.F
1590      - the_model_main.F
1591      and added cost_final_restore.F cost_final_store.F
1592      o With these changes, it is possible to fully separate
1593        the first forward run to compute the cost function (mdthe_main_loop)
1594        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1595        into separate model executions.
1596        This enables better tuning of DIVA to given queue sizes.
1597      o Loss of cost function value in consecutive DIVA runs is
1598        fixed by storing to 'costfinal' file.
1599      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1600        beginning/end of adjoint integration is accounted for.
1601      The current changes apply to TAF-1.4.26.
1602      TAF has one remaining bug, requiring one manual change
1603      (see MITgcm manual).
1604    o cal: synchronized between MAIN and ecco-branch
1605    
1606    checkpoint48i_post
1607    o Changes to restore differentiability of code w.r.t. previous tag
1608      (mostly adding new routines to make list and replacing
1609      pressure by totPhiHyd).
1610    o Updated and merged grdchk package
1611      - has both ADM and TLM checks
1612      - works for single- and multi-proc.
1613      - output cleaned
1614      - worked successfully for parallel DIVA
1615    o genmake:
1616      - Adding -platform=SP4
1617      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1618    o Modif. for DIVA:
1619      ctrl_unpack should not be called in intermediate DIVA interval.
1620      (similar thing would apply for active files such as
1621      tbar, sbar, psbar, which should not be reinitialised;
1622      only relevant for ecco-branch)
1623    
1624    checkpoint48h_post
1625    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1626    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1627    o Added SEAICE_initialHEFF to pkg/seaice
1628    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1629    
1630    checkpoint48g_post
1631    --- EOS:
1632    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1633      store total Potential in totPhyHyd for diagnostics & EOS.
1634    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1635    --- Pressure/geopotential gradient:
1636    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1637    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1638      ( changes results of global_ocean_pressure )
1639    o NLFS + z-coord.: add eta*Rho' contribution.
1640    o accurate phiHyd when using interface-W at the middle between 2 centers
1641     ( changes results of ideal_2D_oce )
1642    o includes r* 2nd term in potential gradient.
1643    
1644    checkpoint48f_post
1645    Merging from release1_p12:
1646    o Modifications for using pkg/exf with pkg/seaice
1647      - improved description of the various forcing configurations
1648      - added basic radiation bulk formulae to pkg/exf
1649      - units/sign fix for evap computation in exf_getffields.F
1650      - updated verification/global_with_exf/results/output.txt
1651    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1652      (SBO) core products, including oceanic mass, center-of-mass,
1653      angular, and bottom pressure (see pkg/sbo/README.sbo).
1654    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1655      to avoid negative values in shallow regions.
1656      - updated verification/natl_box/results/output.txt
1657      - updated verification/lab_sea/results/output.txt
1658    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1659    o Added useSingleCpuIO option (see PARAMS.h).
1660    o Updated useSingleCpuIO option in mdsio_writefield.F to
1661      work with multi-field files, e.g., for single-file pickup.
1662    o pkg/seaice:
1663      - bug fix in growth.F: QNET for no shortwave case
1664      - added HeffFile for specifying initial sea-ice thickness
1665      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1666    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1667      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1668    o pkg/seaice:
1669      - adjoint-friendly modifications
1670      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1671    
1672    checkpoint48e_post
1673    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1674    o dynamics: change definition of computational domain & adapt mom_fluxform
1675      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1676    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1677        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1678        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1679        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1680        inverted_barometer solid-body.cs-32x32x1
1681      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1682    
1683    checkpoint48d_post
1684    o in preparation for r*:
1685     a) use pre-computed gradient of hydrostatic potential:
1686        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1687     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1688        => affects results of glob_oce_pressure (different truncation error)  
1689      update output.txt of ideal_2D_oce & global_ocean_pressure
1690    
1691    checkpoint48d_pre
1692    o in preparation for r*:
1693      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1694      pass the 2 comp. of the grad. as arguments to momentum S/R.
1695      but for the moment, only used if it does not change the results.
1696    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1697    
1698    checkpoint48c_post
1699    Modifications in treatment of initial flux forcing controls
1700    to avoid extra storing of flux fields.
1701    
1702    checkpoint48c_pre
1703    o Added tidal_basin_2d experiment (currently 1D!)
1704    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1705    
1706    checkpoint48b_post
1707    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1708     (modification to pressure gradient not yet implemented)
1709    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1710      (for U & V) that are used for vertical advection of momentum.
1711    
1712    checkpoint48a_post
1713    o In preparation for r*, use temp. array to compute vertical transport
1714       in flux-form momentum pkg. => change results of few test-exp.
1715      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1716                        lab_sea, natl_box & plume_on_slope
1717    
1718    checkpoint48
1719    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1720    
1721    checkpoint47j_post
1722    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1723    o moved adexch from forward_step to addummy_in_stepping
1724    o added exch in ctrl_map_...
1725    o aveFreq.=0. at end of cost_final to avoid overwrite in
1726      reverse checkpointing loop
1727    o Yet more changes in gmredi:
1728      * adgmredi_calc_tensor
1729        avoiding all recomputation of gmredi_slope_limit
1730      * adgmredi_x/y/rtransport
1731        added flag for excessive storing to avoid recomp. of
1732        u/v/rtans, dTdx/y/z
1733        -> this is not really necessary and very memory-consuming
1734      * adgmredi_slope_psi:
1735        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1736      * gmredi_slope_limit
1737        re-activated full calculation of taperfct for case 'ac02'
1738    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1739    
1740    checkpoint47i_post
1741    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1742    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1743      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1744    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1745    o gmredi: fix few bugs.
1746    
1747    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1748    This will be a good checkpoint to plug into the ecco-branch.
1749    o few modif.'s to get latest version adjointed
1750      (mainly kick out code in ini_linear_phisurf)
1751    o modif's to run adjoint with exactConserv
1752    o case GM_BOLUS_ADVEC should be cleaned
1753      S/R gmredi_slope_psi should be cleaned
1754    o verification/carbon now has exactConserv=.TRUE.
1755    
1756    checkpoint47g_post
1757    o time-average AIM output: becomes independent from statvars time-average
1758      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1759    o After TAF bug fix:
1760      Tested adjoint of gmredi package.
1761      Tests were done with checkpoint47 rather than with latest
1762      checkpoint47f_post since the latter is broken for the adjoint
1763      verification/carbon/ contains both ADM and TLM gradient checks.
1764    Here they are, before they get changed/lost/stolen.
1765    Mostly modif.'s to fix numerical sensitivities.
1766    Gradient checks OK for
1767    - GM_taper_scheme:
1768      * clipping
1769      * ac02
1770      * linear
1771      * glw91
1772      * dm95
1773      * ldd97
1774    - GMREDI_OPTIONS:
1775      * GM_VISBECK_VARIABLE_K
1776      * GM_NON_UNITY_DIAGONAL
1777      * GM_EXTRA_DIAGONAL
1778      * GM_BOLUS_ADVEC
1779    in conjunction with data.gmredi parameters to be checked in
1780    in a few minutes under verification/carbon/code/
1781    
1782    checkpoint47f_post
1783    Merging from release1_p10:
1784    o modifications for using pkg/exf with pkg/seaice
1785      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1786        and SEAICE_EXTERNAL_FLUXES
1787      - pkg/exf CPP options EXF_READ_EVAP and
1788        EXF_NO_BULK_COMPUTATIONS
1789      - usage examples are Experiments 8 and 9 in
1790        verification/lab_sea/README
1791      - verification/lab_sea default experiment now uses
1792        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1793    
1794    checkpoint47e_post
1795    o created a tag prior to creating a branch
1796    
1797    checkpoint47d_post
1798    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1799      at the bottom boundary had an erroneous half slip boundary condition
1800    o added bottom drag and no slip boundary condition capabilities to
1801      oceanic pressure coordinates code
1802    o added new verification experiment global_ocean_pressure, this experiment is
1803      also described in the tutorial section of the manual
1804    checkpoint47d_pre
1805    
1806    checkpoint47c_post
1807    o Added a verification experiment for a global cubed-sphere ocean run
1808      -  verification/global_ocean.cubed32x32x30
1809      -  uses pkg/therm_seaice and pkg/bulk_forcing
1810    
1811    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1812    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1813      when using P-coordinate; only implemented for atmospheric config.
1814    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1815      NOTES: requires option NONLIN_FRSURF to be "#define".
1816    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1817    
1818    checkpoint47b_post
1819    Merging from release1_p9:
1820    o pkg/seaice
