4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
8                 fix the singleCpuIO RS version of MDSWRITEFIELD
9       and add a WARNING if using globalFiles=T with multi-processors.
10    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
11      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
12    o tracer advection scheme:
13      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
14       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
15       was not very convenient).
16      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
17       (further tests needed for the implicit DST & Flux-Limiter schemes).
18    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
19      and sRef for convenience, handy, when you want to initialize
20      ptracers in a large domain with a constant non-zero value. Also,
21      untangle ptracers_init.F a little.
22    
23    checkpoint57v_post
24    o change dome exp. to use variable viscosity in side-drag terms.
25    o remove all the files from the cfc_offline test since they are now
26      incorporated into tutorial_cfc_offline which has been producing
27      identical results for a few days of testing
28    o add new parameter: sideDragFactor to enable half-slip-side BC
29      and change side-drag S/R to use viscosity from mom_calc_visc
30      (can switch back by setting sideDragFactor=0.); affects results at
31      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
32       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
33    o vorticity & strain are now computed without masking, to account for
34      no-slip-side BC in variable viscosity calculation ; mask is applied
35      anyway later on, before computing advection/coriolis terms.
36    o modify exp4 to test new obcs support for reading from external files
37      and for passive tracers
38    o fix behavior of ptracers_monitor when monitor output is written to a
39      netcdf-file; still not independent of monitor.F (writes in the same
40      file).
41    o change default value of tRef (put a uniform, meaningful value for ocean
42      & atmos) and initialize sRef (was missing, as Martin mentioned).
43    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
44      to be proportional to enstrophy dissipation length.  Thus,
45       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
46      This is now consistent with Smagorinsky and with the manual.
47    
48    checkpoint57u_post
49    o OBCS and PTRACERS: add open boundary support for passive tracers
50      - either use homogenous (pseudo) v.Neumann conditions or prescribe
51        OB-values from file; this is not different from the way theta and salinity
52        are treated
53      - however, Orlanski-radiation conditions are not supported, and the model
54        will stop if you use pTracers and Orlanski at the same time.
55      - beefed up the rountine obcs_external_fields_load: now only those open
56        boundary values are overwritten with values from files for which there
57        are really files, otherwise the OB-fields remain untouched. This makes
58        it possible to use different OBs at different ends of the domain (as
59        with EXF)
60    o reduce number of exch calls in shap_filt (s2).
61    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
62      truncation level) 4/5 MLAdjust test results (11&12 digits match).
63    
64    checkpoint57t_post
65    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
66    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
67      same truncation, independent of the face number: affects affects several
68      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
69    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
70      note that biharmonic viscosity + no-slip was not tested in any experiment.
71    o fix bug in non-linear free-surf side-drag ; generate new output for
72      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
73    o make mnc honor the writeBinaryPrec flag for most kinds of output
74    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
75    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
76      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
77    o add brackets in multi-terms sum to get same truncation, independent of
78      the face number (manage to get exactly same value of gU,gV at the cs-edge)
79      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
80    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
81      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
82      a maximum grid-scale Reynolds number.  Also, changes all length calculations
83      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
84      Suggested values of viscosity parameters found in mom_calc_visc.
85      Many new viscosity diagnostics available.
86    
87    checkpoint57s_post
88    o Add clearing-house for viscosity calculations, mom_calc_visc and
89      correct numerous bugs in LeithD and Smagorinsky discretizations.  
90      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
91      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
92      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
93      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
94      The Strain-Tension form is now called with useStrainTensonVisc=.true.
95      ViscAhStrain and viscAhTension are now retired.
96    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
97    o In response to JMC's bug report, genmake2 now ignores any soft-links
98      that it finds in the *current* directory when searching for files.
99      Soft-links found in any other source directories will still work as
100      they did before.
101    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
102      a C routine to unlimit the stack size
103    o mnc-ify pkg/aim snapshot vars
104    o mnc-ify pkg/land as requested by Daniel
105    o various changes to mnc including:
106      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
107      - output can now be grouped so that all files within a group
108          change the ITER portion of their names in lock-step together
109      - can now read ("global") PER-FACE (in addition to PER-TILE) files
110          and works with both EXCH1 and EXCH2 (but needs more testing)
111      - writing works for all verification test cases w/ g77 on Linux
112    
113    checkpoint57r_post
114    o make MNC variable initialization happen earlier
115    o add diagnostics for (almost) each term of the momentum Eq.
116    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
117    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
118    o remove MINIMAL_TAVE_OUTPUT option ;
119      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
120    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
121      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
122    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
123    o add time-dependent SST, SSS control
124    o cost terms in ecco/ modularized (new cost_generic.F)
125    o cost_averages routines are modularized (new cost_averagesgeneric.F)
126    o new infrastructure for seaice model vs. obs misfits in seaice/
127      * driver from the_main_loop.F is seaice_cost_driver.F
128      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
129      * gradient check in Exp. 6a of natl_box_adjoint/
130    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
131      (see README file)
132    
133    checkpoint57q_post
134    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
135    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
136      - bug was reported by Jean-Michel and Ian Fenty
137    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
138      update exp. cpl_aim+ocn output.
139    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
140      Needed for high-res. runs with large global files
141      to be able to limit tapelev size
142    o Changed some tests for adjoint:
143      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
144      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
145      * global_ocean.90x40x15/ back to default 3-level checkpointing
146    o Modifications to enable scripted COMMON to MODULE conversion
147      * verification/OpenAD/code/ has necessary scripts and description;
148      * converts, compiles and runs successfully;
149    
150    checkpoint57p_post
151    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
152    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
153      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
154    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
155    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
156      (was already the case for dissipation with mom_vecinv,
157       and also the case for grad.PhiHyd when staggered-timeStep)
158      This will allow to put dissipation out-off the AB time-stepping.
159     Unfortunately, affects truncation error. Update output of exp. that "fails"
160      (cg2d matching number) and leave the others for later: front_relax(10),
161      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
162      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
163    
164    checkpoint57o_post
165    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
166      (2) its ready to be documented during the 20050801 DocFest
167    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
168      for ideal_2D_oce and lab_sea on linux_ia32_g77
169    o set to #undef CTRL_SET_OLD_MAXCVARS_30
170      in global1x1_tot/code_seaice_adj to access indices 32, 33
171      (worth another tag)
172    
173    checkpoint57n_post
174    o adding precip control xx_precip 32
175    o adding swflux control xx_swflux 33
176    o Replacing 10 forcing penalty cost routines by 1 generic.
177    o Implementing partitioning in time-mean and variable adjustment
178      for atmos. state.
179    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
180    o in natl_box_adjoint:
181      * updated exp 1 to 10
182        (but does not have time-mean vs. variable split results yet)
183    o updated global1x1/*_seaice_adj/
184      to incorporate latest changes
185    o enable useSingleCpuIO for mdsio vector routines
186      (applies in particular to tapelev I/O)
187    o removed inefficient K-loop in all active_file*control*.F
188    
189    checkpoint57m_post
190    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
191      and advect_cs (use EXCH-2 and standard cs-32 grid files).
192    o pkg/exch2: filling of face-corner halo regions is optional
193      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
194    
195    checkpoint57l_post
196     tag before updating tutorials (pre-release-2)
197    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
198       for output and interpolation of input fields onto model grid)
199    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
200       Affects results of exp. rotating_tank ; update output.txt.
201    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
202          and taking the square quantity and/or using a fraction-weight field.
203    o fix aim_diagnostics_init.F mate numbers.
204    o add mnc output capability to diagnostics/diagstat and update
205      our cvsignore files for the ACSII output generated
206    
207    checkpoint57k_post
208    o lab_sea now uses diagnostics package and provides a suite of
209      new EXF diagnostics output.
210    
211    checkpoint57j_post
212    o exf
213      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
214        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
215        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
216      * extended diagnostics output
217        - now includes all EXF variables
218        - hs, hl moved to common block
219        - separate S/R for diagnostics, called after ctrl vector is added
220        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
221        - EXFqnet contains true Qnet (i.e. includes qsw)
222      * updated verif. lab_sea, global_with_exf
223      * Rearranging hflux (exf_mapfields -> exf_getforcing)
224        to ensure that diagnostics sees a true EXFqnet
225    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
226    o diagnostics pkg: change pointers so that 1 diagnostic can be used
227      several times with different frequencies.
228    o mnc-ify the thsice package as requested by Daniel Enderton
229      - the monitor--MNC output needs work
230      - many attributes need to be added (most are currently blank)
231    o mnc-ify theaim_v23 package as requested by Daniel Enderton
232      - many attributes need to be added (most are currently blank)
233    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
234    o add Sadourny like discretization to the 4th.O vorticity advection scheme
235    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
236      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
237         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
238    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
239     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
240    
241    checkpoint57i_post
242    o Diagnostics package was changed: diagnostic allocation is now deactivated
243      by setting an empty file name in the namelist (used to be by setting 0 frequency)
244    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
245      add 1rst Order upwind vertical Shear.
246    o add a quick fix for A/B checkpointing in OFFLINE mode
247    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
248      end-run around the C/Fortran linking horror in eesup/src/timers.F
249    o added pkg/runclock: allows user to terminate run based on wall clock
250    o added non-hydrostatic scaling parameter: nh_am2
251    o pkg/my82: futile attempt to make results compiler-independent by adding
252      some "_d 0", etc. no effect.
253    o for mnc output, fill the 'T' coordinate var with myTime and create a
254      separate 'iter' variable for iteration count
255    o pkg/diagnostics:
256      add new capability: output of Global/Regional & per-level statistics ;
257      tested against monitor output (including land & thSIce) on various exp.
258    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
259    
260    checkpoint57h_done
261      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
262      data.diagnostics, data.gchem, data.ptracers) is done.
263    
264    o pkg/diagnostics: prepare for Global/Regional statistics.
265      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
266    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
267      and rename it: DIFFERENT_MULTIPLE
268    
269    checkpoint57h_post
270    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
271    o pkg/diagnostics: change output frequency, now in seconds (instead
272      of Nb of iterations). This requires to change data.diagnostics.
273    checkpoint57h_pre
274    
275    o in mnc, let the user create the output dir if both mnc_outdir_date
276      and mnc_outdir_num are false
277    o add fflags() to pkg/diagnostics which allows one to specify, on a
278      per-file basis, the file precision [default behavior is unchanged]
279    o added diagnostics to pkg/kpp, including computation of mixed layer
280      depth based on a temperature/density criterion
281    o updated verification/natl_box to test the new pkg/kpp diagnostics
282    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
283    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
284    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
285      not mnc -- this mistake was found by JMC and is now corrected
286    
287    checkpoint57g_post
288    o add Adams-Bashforth 3rd Order time stepping:
289      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
290      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
291    checkpoint57g_pre
292    
293    o make lambda[Theta,Salt]ClimRelax spatially varying
294      (default remains spatially uniform constant based on tau)
295    o added new control variables
296      * init. uVel, vVel, etanN
297      * lambda[Theta,Salt]ClimRelax
298    o separate masks used for ctrl_pack/unpack 'from write_grid' output
299      (suggested by G. Forget)
300    
301    checkpoint57f_post
302    o add parameter "baseTime" = model base time = time at iteration zero
303      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
304      account for baseTime shift

306    checkpoint57f_pre
307    
308    o mnc-ifying the seaice package
309    o introduced an alternative length scale calculation for use in the limiting
310      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
311    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
312    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
313      as well as grad(vort3).  Made it compatible with both approximate form
314      for the cubed sphere and full form of these gradients.  Added flag
315      useFullLeith to select between approximate and full form.  
316    o add "d0" in getcon.F to reduce differences between compilers/platforms
317      update output.txt of exp. fizhi-gridalt-hs
318    o change port_rand funtion to allow to set the seed.
319    o fix obscure MNC bug involving conversion between reals and integers
320      - it caused no problems with certain (eg. gcc, ifc) compilers but the
321        new version is now more standards-compliant
322    o adjoint-related modifications
323      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
324      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
325      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
326    
327    checkpoint57e_post
328    o Adding eddy stress controls a la Ferreira et al.
329    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
330    
331    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
332      update output.txt of exp. fizhi-gridalt-hs
333    o add more "Z" dimensions and associated coordinate vars to MNC
334    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
335    o parameter calendarDumps: when set, approximate months (30-31 days) and years
336      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
337      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
338      months and years.  Requires pkg/cal.
339    o diagnostics: add pickup functionality
340      - off by default for backwards compatibility
341      - current version only uses MDSIO -- MNC will be added
342    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
343    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
344    
345    checkpoint57d_post
346    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
347    o modify verification/ideal_2D_oce so that it tests the creation of mnc
348      output from the diagnostics package
349    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
350    o make genmake2 more portable by using ".$FS" instead of ".f" for more
351      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
352    o add coordinate variables to the MNC output from the diagnostics package
353    o change MNC-flags default value: true when useMNC=TRUE
354    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
355      the ability (off by default) to read the grid information using MNC
356    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
357    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
358    o do snap-shot diagnostics at the middle of the time-interval (instead of
359      at the end).
360    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
361      new test for AIM with thSIce + slab-ocean
362    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
363    o move state variable diagnostics to the beginning of the time step ;
364      (note: still needs some work specially for snap-shot diagnostics)
365      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
366    
367    checkpoint57c_post
368    o Change testing option (-ieee) to get closer agreement between g77 & ifort
369    o generate new output.txt files on faulks with g77 & the new -ieee option
370    checkpoint57c_pre
371    
372    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
373      update output.txt of exp. global_ocean.90x40x15
374    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
375      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
376    o add saltFlux(+File) forcing capability with periodicExternalForcing
377    o allow to use pkg diagnostics for GM-Redi & ThSIce output
378    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
379    o improvements for the MNC output from DIAGNOSTICS:
380      - correct handling of the unlimitied dimension
381      - all dims now have associated coordinate variables
382      - variables located at U, V, and Corner ("Z") points are now written
383        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
384        *all* data points are output
385    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
386    o added pkg/seaice/seaice_monitor.F
387    o mdsio_readfield.F can now read files visible only to master MPI process.
388    o pkg/seaice: some test code for ice-modified ocean stress
389    o exf_getffields interpolation defaults to bilinear for all scalar forcing
390      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
391      spurious negative numbers for precipitation and humidity.  Will cause
392      some small numerical differences for integrations using pkg/exf/exf_interp.F.
393    o pkg/ctrl/
394      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
395        May be enabled via doPackDiag
396      *  introduce z-scaling of
397         + gradient (doZscalePack) and
398         + control (doZscaleUnpack)
399    o pkg/mdsio/
400      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
401      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
402    
403    checkpoint57b_post
404    o simplify options in diagnostics_fill arguments (remove weird combinations)
405    o fix MNC coordinate variables so that they now contain per-face index
406      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
407      general, EXCH2 grids are only aligned to a "local" coordinate system
408    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
409    o Implement instantaneous output within pkg diagnostics:
410      setting a negative frequency in data.diagnostics produces
411     "snap-shot" output (as opposed to time-average if freq > 0)
412    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
413      NOTE: change ptracer diagnostics name: use 2 characters to work with
414            more than 9 tracers. Add also diagnostics of advect & diffus flux.
415    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
416      becomes the coordinate variable for the 'T' dimension
417    o add CF-style coordinate variables to MNC
418      - just a first cut:  numbers are meaningless on the cubesphere and
419        missing along the T axis but otherwise it works!
420    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
421    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
422    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
423      this is based directly on what the model compute, so that the content of
424      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
425    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
426    o clean up build options files for SunOS, in particular
427      - remove -traditional from xmakedepend
428      - change -xarch=v9 to -xarch=native for f77
429      - restore use of make (not gmake)
430      - add CC=gcc if using g77
431    o changes per discussion of AM, JMC, & EH3 today:
432      - move redundant "grid" variables out of "state" -- in preparation of
433        creating proper CF-style coordinate variables and in recognition
434        that any/all grid variables can be easily copied (eg. w/NCO) from
435        the grid files into any of the other NetCDF files
436      - *always* output grid variables with MDSIO (this will eventually be
437        changed)
438      - output MNC grid file if useMNC is true
439    o every instance of _END_MASTER() has been found and replaced with
440      _END_MASTER( myThid ) in order to satisfy certain picky Sun
441      preprocessors
442    o re-arrange diagnostics pkg initialisation:
443     - allow each package to extend the available diagnostics list
444     - add some checking and fix small problems (multi-threaded, ...)
445     - new S/R diagnostics_fill (replace fill_diagnostics):
446       look through the short list of active diag. (instead of the long list)
447       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
448    
449    checkpoint57a_post
450    o this set of changes restores TAMC compatibility
451      tested for global_ocean.90x40x15 adjoint on trough
452      (what a pain)
453    
454    checkpoint57a_pre
455    o some modifs in tools/build_options for sunos
456    o call ctrl_pack for ctrl at end for optimcycle=0
457    
458    checkpoint57
459    o add horizontal bi-harmonic viscosity for vertical velocity
460      - new parameter viscA4W (defaults to viscA4)
461      - affects only non-hydrostatic code
462      - to be done: no-slip lateral boundary conditions
463    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
464    o implement Implicit Vertical advection for pTracers
465    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
466      (implemented also for implicit vertical diffusion & advection)
467    o OBCS: extend application of tracer open boundary conditions
468      to a strip beyond the boundary of width Olx/Oly
469    o add call monitor to TAF set of required calls (flow directives)
470      and include in natl_box_adjoint
471    o untangle a few ifdefs related to cost, ctrl, autodiff
472      untangel a few ALLOW_ECCO_OPTIMIZATION
473    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
474      (theta2, salt2 in ecco_cost_weights)
475    
476    checkpoint56c_post
477    o OBCS as control variables
478      - update ctrl_ad_diff.list, obcs_ad_diff.list
479      - remove balance of obcs controls from default
480      - fix index bug nobcs in ctrl_init
481      - fix dummy fields filen in ctrl_pack
482      - add dummy weights for obcs
483    o lsopt: comment out fort.94 output
484    o optim:
485      - remove unnecessary header files
486      - adjusted namelists
487      - add xerbla.F to Makefile
488    o exf:
489      - multiple modifications of exf_check_range
490      - unit change in exf_init_runoff from [m/year] to [m/s]
491    o mdsio:
492      - i/o-vector change debugLevel from debLevA to debLevB
493    
494    checkpoint56b_post
495    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
496      is called from DO_THE_MODEL_IO
497      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
498      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
499      - clean up PTRACERS_WRITE_TIMEAVE a little
500    o add another verification experiment that tests both the cfc-pkg and
501      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
502      reactive tendencies treated inline with regular timestepping
503    o testreport previously did a lousy job of comparing small numbers, so
504      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
505      implemented in the little c-progam tmp_cmpnum.c which is embedded in
506      testreport.
507    o ptracers_monitor: bug fix for MPI
508    
509    checkpoint56a_post
510    o GCHEM: finish reorganizating the package
511      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
512        (introduces another 3D-array for each passive tracer, but only if
513        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
514        gchemTendency is not needed because the timestep is done separately)
515      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
516      - GCHEM is now---more or less cleanly---separate from PTRACERS
517      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
518        so clear to me how that should be done in a general way.
519    o CFC: improve formatting of output in CFC_ATMOS
520    o PTRACERS:
521      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
522        that ALL experiments with ptracers enable can be checked. This makes
523        GCHEM_MONITOR obsolete.
524      - include a runtime parameter PTRACERS_monitorFreq that defaults to
525        monitorFreq
526      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
527    o add PTRACERS (PTR0[1-5]) to testreport output
528    o exf_check_range:
529      * default changed to .TRUE.
530      * will check values for niter0 if debLevA, every timestep if debLevB
531      * STOP in exf_check_range if 'out of range'
532      * range chosen generous to allow for potential extema
533      TBD: a version with stricter range
534           permitted range would be runtime parameters
535    o GMredi:
536      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
537      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
538      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
539    o GCHEM:
540      - move call to GCHEM_FORCING_SEP, so that it is now called before
541        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
542      - introduced a useGCHEM runtime flag and applied it everywhere.
543      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
544        this flag is now only visible within GCHEM-pkg routines.
545      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
546        be replaced by a 3D array that is computed before thermodynamics; for
547        this, the tracer ID iTracer had to be included into the parameter list
548        of ptracers_forcing
549      - set up forward_step to call gchem_forcing, that will replace
550        gchem_forcing_int in ptracers_forcing
551      - cleaning up
552    o small cleaning of exch2: remove files that are also in eesupp/src
553    
554    checkpoint56
555    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
556    o mnc: cleanup "full" files--fixes out-of-memory problem
557    o ECCO-GODAE
558      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
559      * fully merged and updated from SIO code
560        windstress sign change affects
561        - exf_inscal_[u/v]stress
562        - sign of xx_tau[u/v] adjustments
563        - signs in cost_scat
564      * ctrl_get_gen: avoid update of tau[u/v] for first few days
565      * natl_box_adjoint updated and compressed
566      * 2-level checkpoint switch added
567        (tested in EXP. 1 of natl_box_adjoint)
568      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
569    o SVD
570      * first complete, non-hacked version for SVD calculations
571      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
572        performed via direct access files admtlm_vector.it????
573        (via ctrl_[un]pack)
574      * optimcycle is used for ARPACK iteration counter
575        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
576      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
577        and add linear transforms where necessary
578      * controls are initial/final SST, SSS (can be extended; need to check
579        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
580    o mdsio: filename info to both stderr, stdout
581    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
582      from sign change
583    
584    checkpoint55j_post
585    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
586      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
587    o add consistent build directories and .cvsignore files to verification
588    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
589    o make all subroutines 30 or less characters in length for certain older
590      compilers to work (a thorough search only turns up two routines in
591      pkg/ptracers)
592    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
593      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
594    
595    checkpoint55i_post
596    o change arrays for total vertical diffusivity (2.D if explicit,
597      3.D if implicit) ; each ptracer uses its own background value.
598    o added mnc/NetCDF output capability to ocn_compon_interf
599      - added bits to verification/cpl_aim+ocn so that it can run on
600        ITRDA and other clusters without the mpirun "-wd" option
601    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
602      configuration
603    o give MNC the ability to create additional files rather than
604      exceeding a specified file size limit "MNC_MAX_FILESIZE"
605      - the default is just less than 2GB which is a practical limit
606        on many systems
607    o Compute the non-local term using either KPP vertical diffusivity (=default)
608       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
609    
610    checkpoint55h_post
611    o add verification test "vermix"
612    o remove all the *_ioinc flags and replace with the single global
613      outputTypesInclusive flag
614    o allow to set a vertical profile of vertical diffusivity for T & S
615    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
616    o useMNC moved from data.mnc to data.pkg
617    
618    checkpoint55g_post
619    o Renaming carbon AD experiments to comply with testreport conventions
620    o Updating adjoint of Held-Suarez hs94.1x64x5
621    o Fixing directives for non-ECCO forward_step, after ECCO directives
622      have been fixed to avoid recomp. of do_oceanic_phys
623      Works well for global_ocean.90x40x15,
624      but recomp. issue remains for carbon
625    o Updating adjoint output for natl_box_adjoint after
626      pkg/ecco has been modified (see taga c55d_post)
627    
628    checkpoint55f_post
629    o rename to timeave_init_fixed
630    
631    checkpoint55e_post
632    o some delicate re-shuffle of store directives to avoid one
633      extra call of do_oceanic_physics
634      affects ecco_the_main_loop.F, do_oceanic_physics.F
635      checkpoint_lev1_directives.h
636    o NB: this may break global_ocean adjoint temporarily,
637      but it is clear how to fix it. Will do later, need this now.
638    
639    checkpoint55d_post
640    o ECCO specific cost function terms (up-to-date with 1x1 runs)
641    o ecco_cost_weights is modified to 1x1 runs
642    o modifs to allow observations to be read in as
643      single file or yearly files
644    o enable to read exf forcing fields as either
645      single file or yearly files (flag useExfYearlyFields)
646    checkpoint55d_pre
647    
648    o switch between 2-level and 3-level checkpointing
649    o add ability of MNC to write local and "partial" (eg. 2D slices where
650      the full 3D field is never actually stored) arrays to NetCDF files
651      with the correct (that is, the complete multi-dimensional) set of
652      array indicies
653      - used in mom_vecinv() to write the diagFreq output
654      - tested (demonstrated) in verification/aim.5l_cs
655    o further mnc-ification
656      - add verification/lab_sea to the list with mnc setups
657      - fix undefined mnc v-names in cd_code
658      - add kpp to mnc output (both snapshot and timeave)
659    o non-hydrostatic code
660      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
661        in calc_gw.F
662      - defaults to viscAh
663      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
664        friction or Leith) in non-hydrostatic mode, as long as there is
665        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
666    o pkg/cost
667      extend simple cost functions to treat time mean quantities
668      (T,U,V) via cost_accumulate_state from cost_tile
669    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
670        be 2 times larger than the minimum size the advection scheme requires.
671        now get a perfect conservation of salt in advect_cs test-exp (updated)
672    o GGL90 (Gaspar's TKE mixed layer)
673      - add horizontal diffusion of TKE, requires exchanges in
674        do_fields_blocking_exchanges, horizontal diffusivity is zero by
675        default. In OPA there is no horizontal diffusion of TKE but the
676        mixing coefficients are computed from a horizontal average of TKE of
677        6 points or so. I think that diffusion has a little more physical
678        justification.
679      - clean up ggl90_calc in the hope of reducing memory usage (this hope
680        was in vain)
681      - mask tke-variable in ggl90_init
682    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
683    o fix biharmonic diffusion on CS-grid.
684    o more obcs stuff
685      - added obcs_external_fields_load as an alternative to the EXF-pkg option
686        for reading boundary values. This routine is called from
687        obcs_prescribe_read
688      - updated obcs_check
689      - changed sponge layer relaxation parameter units for days to seconds
690      - turned off sponge layer by default
691      - changed argument list of OBCS_CALC to myTime+deltaTclock
692      - fixed about 35 bugs in obcs_external_fields_load
693    
694    checkpoint55c_post
695    o obcs stuff
696      - new runtime flags useOBCSprescribe, useOBCSbalance
697      - re-arranged obcs_calc
698      - moved exf_getobcs to obcs_prescibe_read
699        obcs_prescibe_read is called after ORLANSKI stuff
700        and independent of it (executable can contain all).
701      - updated obcs_check
702      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
703        These may be necessary only if tangential velocities are
704        prescribed at OB, not sure, needs testing.
705    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
706      which simplifies the calls and passes the ifc check-bounds test
707    
708    checkpoint55b_post
709    o add a 2D scalar, Z location, exchange_2 routine.
710    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
711      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
712      affects advect_cs results (for the wrong reason): update output.txt
713    o use a more standard discretization for biharmonic viscosity ;
714     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
715      affects results of dome set-up: update output.txt
716    o fix gad_advection.F (CubedSphere part), back to version 1.23
717    o fix bug in mom_vi_del2uv.F (CubedSphere part).
718    
719    checkpoint55a_post
720    o merged code to
721      * prescribe/read time-dependent open boundaries
722        (works in conjunction with exf, cal)
723      * sponge layer code for open boundaries
724      * each boundary N/S/E/W now has its own CPP option
725        (healthy for the adjoint)
726    
727    checkpoint55
728    o up-to-date adjoint of previous breaks
729      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
730      - global_ocean_ebm: adjoint still needs fix (TLM ok)
731      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
732      - carbon: * remove tr1-related adjoint verification
733                * add ptracer as control variable
734    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
735      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
736    
737    checkpoint54f_post
738    o in verification/carbin/ remove experiment related to
739      ALLOW_PASSIVE_TRACER (array tr1 etc)
740      code_ad/ input_ad/ results_ad
741    
742    o add two new packages
743      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
744        + subject to optimization (memory)
745      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
746        + subject to reordering (many GOTOs in the original code)
747        + so far opps is called for every (i,j) point, and then operates in
748          the vertical; one may want to reorder the scheme in order operate in
749          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
750          fields)
751    o overhaul of IO so that we now have flags for MDSIO and/or MNC
752      - all verification tests compile and run with linux_ia32_g77
753      - defaults are compatible with current input files--nothing
754        should change if you were not previously using MNC
755      - MNC output has been added in numerous places (eg. timeave)
756        but there are still a few writes not yet do-able with MNC
757        (this is in progress)
758      - flags now allow for either/or/both use of MDSIO and MNC and
759        documentation will soon follow
760      - numerous small formatting cleanups for ProTeX
761    o add version info (via BUILD_INFO.h) to MNC and stdout
762    
763    checkpoint54e_post
764    o add two new packages
765      - pp81 (Packanowski and Philander, 1981), Richardson number and
766        stratification dependent mixing
767      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
768      - these scheme operate in a similar manner as KPP (without ghat, of
769        course), however there is only one diffusivity that is used for both
770        temperature and salinity (and passive tracers)ç
771    o add offline package
772    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
773      provided by Stephanie Dutkiewicz
774    o genmake2: add ability to search for C compilers and cleanup test output
775      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
776    
777    checkpoint54d_post
778    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
779    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
780      leading to additional shift by 5 days each year of integration
781       (i.e. leading to considerable offset over the years)
782    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
783    o start with no AB and no initial filtering (staggerTimeStep):
784      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
785    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
786      (external loading & cpl import/export stay in forward_step.F)
787    o update coupling interface to work with new staggerTimeStep
788    o change MDSIO ptracers_pickup.
789    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
790    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
791    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
792    
793    checkpoint54c_post
794    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
795      this affects (truncation error) output.txt of test-exp:
796       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
797    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
798    o change Qnet to always be the net heat flux, (+upward).
799      affects (truncation error) output of natl_box exp.: updated
800    o define the max number of passive tracers in PTRACERS_SIZE.h
801    o start to test mnc routinely in exp0
802    o add sea-ice loading (sIceLoad) as a new forcing field.
803    
804    checkpoint54b_post
805    o add testreport "-j JOBS" option for parallel builds (tested and pretty
806       impressive on Altix and Opteron systems)
807    o diagnostics can now write NetCDF files through the mnc package
808    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
809    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
810    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
811      affects (truncation error) output of lab_sea & natl_box exp.: updated
812    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
813    
814    checkpoint54a_post
815    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
816    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
817    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
818    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
819      + internal_wave (shift in writing cg2d_ini_res)
820    checkpoint54a_pre
821    
822    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
823      - modified verification/lab_sea and natl_box_adjoint accordingly
824    
825    checkpoint54
826    checkpoint53g_post
827    o prepare splitting of thermodynamics: store convect.counter in common block
828    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
829      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
830    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
831    o new parameter "nShapS": allow to treat differently S from T (nShapT)
832    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
833    o restore adjointability
834    
835    checkpoint53f_post
836    o modifications that affect AIM experiment results (update output.txt):
837      - no advection of S at top interface Nr (pkg/generic_advdiff)
838      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
839    o AIM pkg:
840      - include stability function into surf.Flux derivative relative to Tsurf
841      - calculate clear-sky radiation & surface temp. change (for diagnostics)
842    
843    checkpoint53e_post
844    o merged cylindrical coord configuration
845    o added rotating_tank experiment
846    checkpoint53e_pre
847    
848    checkpoint53d_post
849    o faulks upgraded: re-generate output.txt that have changed:
850       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
851    o Added Bryan and Lewis, 1979, vertical diffusivity profile
852    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
853    o added Sadourny discretization of Coriolis
854      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
855      - re-enabled use of omega3 (useAbsVorticity)
856    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
857      vector-invariant equations
858      - note: does *NOT* yet use same variable visc. for no-slip BC's.
859    o recoded the lateral boundary conditions for non-hydrostatic w, this time
860      hopefully without new bugs
861      - still to do: biharmonic friction for non-hydrostatic w
862    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
863    o regenerated output for global_ocean_ebm (using -ieee)
864    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
865      of mom_common/
866      - simple re-arrangement of instructions within computing loop
867    checkpoint53d_pre
868    
869    checkpoint53c_post
870    o new version of coupler for AIM+thSIce and Ocean models
871     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
872     - land: change Evaporation of snow
873     - aim with thSIce: fix bug in snow-precip.
874    o changes to calc_gw.F
875     - bug fix for w^2 term near the bottom boundary
876     - (hopefully) improve the lateral slip boundary condtions for use with
877        partial/looped cells
878      - because the bug fix changes two verification experiments anyway (exp5
879        and plume on slope), change the lateral boundary condition from half slip
880        to the value of no_slip_sides
881    o ebm package wasnt quite up to the parallel task. Fixed that.
882    o Adjoint of EBM package + verification
883      * TLM OK
884      * ADM not sufficient accuracy yet (needs further testing)
885    
886    checkpoint53b_post
887    o Commiting new energy balance model to repository
888      * package is pkg/ebm
889      * verif. is verification/global_ocean_ebm
890      * references are in ebm_driver.F
891    C      * X. Wang, P. Stone and J. Marotzke, 1999:
892    C        Global thermohaline circulation. Part I:
893    C        Sensitivity to atmospheric moisture transport.
894    C        J. Climate 12(1), 71-82
895    C      * X. Wang, P. Stone and J. Marotzke, 1999:
896    C        Global thermohaline circulation. Part II:
897    C        Sensitivity with interactive transport.
898    C        J. Climate 12(1), 83-91
899    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
900    C        Destabilization of the thermohaline circulation
901    C        by atmospheric eddy transports.
902    C        J. Climate 7(12), 1870-1882
903    o Will need long integration testing.
904    checkpoint53b_pre
905    
906    o created pkg/mom_common in preparation for variable viscosity code
907    o renamed and split ini_mnc_io
908    o pkg/land: only liquid water can diffuse or run-off
909    o AIM using land: soil wetness availability account for snow
910    o added printMapIncludesZeros to EEPARMS namelist
911    
912    checkpoint53a_post
913    o restore TAMC compatiility for exf_constants.h
914      (no usage of _d in .h)
915    o Additional storing in KPP in an attempt to fix
916      TAMC problem with adjoint of KPP code.
917      (no success...)
918      Identical code works fine with TAF.
919    o Fixed verification/natl_box_adjoint experiments.
920      Initial conditions for Experiments 4 and 5 are now
921      set to "SEAICE_initialHEFF=0", which is more reasonable,
922      and hence gives results closer to that of Experiment 2.
923      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
924    
925    checkpoint53
926    o stable checkpoint with up to date adjoint
927      TLM tests only run for 1st grdchk at the moment. Its unclear if
928      this is a code problem or a problem with resetting code for g_
929      variables that is being autogenerated wrong.
930      Otherwise:
931       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
932       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
933         are both still in chaos following their security messes.
934    
935    checkpoint52n_post
936    o various build (mostly genmake2) changes including:
937      - ability to build/run more easily within Cygwin and MacOS X
938      - more complicated Makefiles with a stronger dependence on Gnu Make
939    o pkg/seaice modifications
940      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
941        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
942        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
943      - changed proxy for geostrophic velocity and updated
944        verification/lab_sea/results/* accordingly
945      - removed ADI dynamic solver from pkg/seaice
946      - replaced all occurrences of 1/CSTICE or 1/CSUICE
947        they caused a segmentation fault under certain circumstances
948      - removed unused field WATR
949    o bug fix in exf-package:
950      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
951         now reflect that.
952    o small fixes in the cal-package:
953      - set reference date to first of January for the 'model'-calendar
954      - failing of cal_CheckDate in cal_FullDate now actually results in a
955        warning
956    o small modifications in exf-package to increase flexibility:
957      - change climtempfreeze from a constant to a runtime parameter that
958        is specified in data.exf_clim (default = -1.9)
959      - introduce runtime parameter windstressmax (default = 2.0) that is
960        specified in data.exf
961    o fix in pkg/thsice:
962      - update Evap (Tsf changes) to be consistent with Latent heat flux
963      - maintain snow precipitation unchanged (even if Tsf >=0).
964     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
965    
966    checkpoint52m_post
967    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
968      this does not change any of the results, because myIter=0 in swfrac always
969      lead to jwtype=2 (the default anyway), but the call makes little sense
970      as a default
971    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
972    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
973      atmospheric model (AIM) to use it ; add a "slab ocean" component.
974    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
975    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
976    o extending useSingleCpuIO option to work with new exch2 I/O format
977      - old-style, missing-tile I/O is still accessible by defining CPP
978        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
979    o monitor package can write to NetCDF files and/or STDOUT
980    o fix re-definition bug in MNC_GRID_INIT_ALL()
981    o doc/api_reference added
982      - a framework for building an API Reference Manual using all
983        the "protex" comments embedded in the code
984      - see pkg/generic_advdiff, pkg/mnc for examples
985    o MNC:
986      - make myThid the last argument for all subroutines
987      - new default for the grid files: NO halos
988      - add useMNC and other run-time flags
989      - separate per-file-group handling of the unlimited dimension
990      - early initialization of MNC w/ flags read at the eeboot stage
991        and lookup tables set in initialize_fixed
992      - write all MNC output to a freshly-created directory
993    o thermodynamics sea-ice (thsice) is now tested with testreport.
994    o test exp. advect_cs: use the standard cs32 grid ; update output.
995    o Added functionality to grdchk:
996      pick global i,j,k position (or nearest wet) where to perform check.
997    
998    checkpoint52l_post
999    o new land formulation:
1000      a) use ground enthalpy as prognostic variable to ensure exact
1001         energy conservation.
1002      b) account for water temperature and for latent heat of freezing
1003         in all processes (rain, run-off, ground storage)
1004      c) compute surface and ground temperature implicitly.
1005    o aim_v23 modification for new land model:
1006      a) Treat separately land / ocean / sea-ice surface fluxes
1007         to allow implicit computation of land & sea-ice surface temp.
1008      b) add snow precipitation.
1009    checkpoint52l_pre
1010    
1011    o fix problem (when 1 tile is empty) in min/max monitor.
1012    o fix bug in timeAve (u,vZetatave in common block)
1013    o no restoring terms under ice for pkg/seaice
1014    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1015    o bug fix for pkg/seaice pickups
1016    o change MNC call locations and add coordinate attributes
1017    o mask vorticity at the corner ; affects global_ocean.cs output
1018    o fix ini_curvilinear_grid ; test CS experiments with mpi
1019    o aim.5l_cs: modify sea-ice fraction input file ; update output
1020    o exf: Adding simple range check routine for exf fields after read
1021    
1022    checkpoint52k_post
1023    o removed top-level directory "diags"
1024      - we migrated these functions to pkg/timeave a long time ago
1025    o fixed bug introduced in pkg/monitor
1026    o accuracy ctrlprec = 32 insuffient for gradient checks using
1027      averaged fields (I/O via cost_averages)
1028      -> use ctrl.h in active_file*.F to control I/O precision.
1029    o paramter list of CALL ADTHE_MAIN_LOOP
1030    o added initial do_the_model_io to ecco
1031    o set all ...Freq to zero after cost_final
1032      taveFreq, dumpFreq, pChkptFreq
1033    o MAIN and ECCO differentiability restored
1034    
1035    checkpoint52j_post
1036    o fix nchklev in tamc.h for global_ocean...
1037    o Bringing flow and store directives up-to-date
1038    o Really weird thing!
1039      call do_the_model_io from the_main_loop with parameters
1040      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1041      TAF places a faulty re-call of initialise_varia
1042      after cost_final call which should not be there!
1043    checkpoint52j_pre
1044    
1045    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1046      error messages
1047    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1048    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1049      debug output
1050    o modfied mdsio_writefield.F to handle non-global files under exch2
1051    o update AIM Cubed-Sphere exp (aim.5l_cs):
1052      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1053    o update AIM Equatorial Channel exp:
1054      use standard aim_v23 pkg and change the SST fields to be more realistic.
1055    o globalFile now works with exch2
1056    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1057      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1058    o limit timeave output for hi-res integrations
1059    
1060    checkpoint52i_post
1061    o removed CPP_EEOPTIONS.h from verification/*/code
1062    o updated the tiling for global_ocean_pressure
1063    checkpoint52i_pre
1064    
1065    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1066      the old pkg/aim).
1067    
1068    checkpoint52h_pre
1069    o shortened offending lines in exch2_send_rx?.template
1070    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1071    o genmake2: add build & execute test for NetCDF code
1072    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1073      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1074    o added useSingleCPUIO flag to monitor.F and mon_out.F
1075    o added temporary hack for sea-ice dynamics on the cube:
1076      metric terms are ignored and it is assumed that
1077      there is no sea-ice on cube faces 1, 2, 4, and 5.
1078    
1079    checkpoint52f_post
1080    o added exch2 cube routines to pkg/exch2
1081    o modified hs94.cs-32x32x5 to use it
1082    o added new grid files to hs94.cs-32x32x5
1083    checkpoint52f_pre
1084    
1085    checkpoint52e_post
1086    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1087      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1088    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1089      to work with implicit vertical advection and AB ;
1090    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1091    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1092     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1093    checkpoint52e_pre
1094    
1095    o fix bug in impldiff when Nr=1 or Nr=2.
1096    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1097    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1098    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1099      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1100    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1101    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1102    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1103    
1104    checkpoint52d_post
1105    o re-tiled many expts to allow comparison in multi-processor mode
1106      - updated output accordingly
1107      - changed hs94.128x64x5 to use intial T from file rather than use the
1108        random number generator
1109    o add infrastructure in model routines for fizhi and gridalt packages
1110    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1111    o changes to permit hi-res, cubed-sphere, configuration
1112      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1113      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1114      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1115        of surface winds for the cube
1116      (A verification experiment, based on global_ocean.cs32x15, but with
1117       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1118       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1119       complete with example surface forcing files and matlab scripts to look
1120       at the output and compare it with that of global_ocean.cs32x15.)
1121    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1122       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1123       to conform to the common rule.
1124    o check-in the first version of the coupler + interfaces for multi-components
1125       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1126       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1127       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1128       - ocean and atmos. share the same horizontal grid (no interpolation).
1129       - exchanges between component and coupler is done in forward_step
1130    o new verification experiment, cpl_aim+ocn:
1131       coupled ocean - AIM atmosphere on cs32 grid.
1132    
1133    checkpoint52d_pre
1134    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1135    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1136    
1137    checkpoint52c_post
1138    o Fixing OPTIONS files for use of exf:
1139      - ALLOW_ECCO not needed
1140      - ECCO_CPPOPTIONS.h should not be included from
1141        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1142        as has been the case in the past
1143      - All cal/exf related options are currently set in
1144        single header file. Should remain so until we
1145        agree on a consistent new policy.
1146    o Removed all CPP options for cal package.
1147      cal has no more CPP options.
1148    o modified STOREs in GAD_ADVECTION
1149    o corrected key comp. for passkey
1150    
1151    checkpoint52b_post
1152    o new version: "thsice" of thermodynamic sea-ice pkg:
1153     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1154     - modify fluxes but do not change theta directly;
1155     - light cleaning of bulk_force pkg (still needed with thsice).
1156     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1157       + output_thsice.txt to test thsice & bulk_force pkgs.
1158    o put back grid & coriolis monitor output.
1159    checkpoint52b_pre
1160

1163    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1164      (need info on NUMBER_OF_PTRACERS)
1165    o missing PTRACERS headers in some routines
1166    o default tamc.h in pkg/autodiff supposed to crash
1167      to ensure proper customization
1168    
1169    checkpoint52a_post
1170    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1171      - moved surfaceTendencyTice from pkg/seaice to main code
1172      - subroutine FREEZE_SURFACE now limits only surface temperature
1173        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1174        => new output.txt for global_ocean.cs32x15 & global_with_exf
1175      - keep the old version of FREEZE for backward compatibility;
1176        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1177      - corresponding modifs for TAF directives
1178    o added surface flux output variables to TIMEAVE_STATVARS

1185    o some bug fixes for #undef REAL4_IS_SLOW
1186    
1187    checkpoint52 = ecco_c52_e35
1188    o after testing adjoints of checkpoint51u_post
1189    
1190    checkpoint51u_post
1191    o this is the post-merge tag of the ecco-branch
1192      (needs another clean checkout and re-testing)
1193    o various natl_box_adjoint configs and results
1194      but no input fields
1195    o obcs adjoint not yet merged!
1196    o adding ECCO global 1x1 and 2x2 degree configs
1197    o updated/extended some store directives for seaice
1198    o pkg/ecco now containes ecco-specific part of cost function
1199    o top level routines the_main_loop, forward_step
1200      supersede those in model/src/
1201      previous input data.cost now in data.ecco
1202      (new namelist ecco_cost_nml)
1203    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1204    
1205    checkpoint51t_post
1206    o this is the pre-merge tag of the ecco-branch
1207    
1208    checkpoint51s_post
1209    o cleanup: removed various obsolete #define-s
1210    o pkg/grdchk
1211      - renamed 'ph-grd 3' to 'grad-res'
1212      - merged from ecco-branch
1213        (remaining bug fixes for obcs gradient checks)
1214      - additional high-precision output for testreport
1215        (grep for 'precision_grdchk_result')
1216    
1217    checkpoint51r_post
1218    o cleaned up or removed CPP_OPTIONS.h files
1219    o updated results for some of the tests to reflect the new
1220      optfiles (-ieee: -O0 instead of -O3)
1221    
1222    checkpoint51q_post
1223    o cd_code:
1224      - moved cd_scheme.F -> cd_code_scheme.F
1225      - separate read_checkpoint from cd_code_ini_vars.F
1226      - separated cd_code part from write_checkpoint
1227      - updated AD_SOURCE, generated .flow

1236    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1237    
1238    checkpoint51p_post
1239    o create initial cd_code package
1240      - WARNING: the initialization of fields within packages
1241        is broken because INI_FIELDS (where READ_CHECKPOINT is
1242        called) is called *before* PACKAGES_INIT_VARIABLES.
1243        This seems to be backwards since
1244        1) its important to initially zero the entire field including
1245           the "halo" region
1246        2) zeroing needs to be done *before* reading pickup info
1247           and the pickup call might or might not happen in any
1248           particular run
1249      - this needs an overhaul for R2
1250    o cleanup verification/*/code/GMREDI_OPTIONS.h

1285      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1286      - subroutine FREEZE now limits only surface temperature
1287        (this means new output.txt for global_ocean.90x40x15,
1288         global_ocean.cs32x15, and global_with_exf)
1289    o added surface flux output variables to TIMEAVE_STATVARS

1524      to timestep.F
1525    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1526    o re-generate output for highly sensitive test-exp:
1527       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1528    
1529    checkpoint50b_pre
1530    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1531    o corrected CPP option mismatch in exf_Bulk... functions for case
1532      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1533    
1534    checkpoint50a_post
1535    o Bug fix for merging between c50 and KPP.
1536      ikey was passed from thermodynamics to kpp_calc via
1537      common block rather than being recomputed in kpp_calc,
1538      in contradiction with new key itdkey.
1539      New key ikppkey created, and tamc.h headers updated.
1540    
1541    checkpoint50
1542    - 2nd step of merge with ecco-branch:
1543      merge changes in ecco-branch back into main trunk
1544    - bug fix in find_alpha
1545    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1546    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1547    - merged some sliced AD support routines
1548    
1549    checkpoint49
1550    merged from ecco-branch:
1551    o exf:
1552      - Enable initialisation of forcing fields to constant
1553        (runtime) values.
1554      - in exf_getffields.F
1555        Reduce i-/j-loop to interior domain, discarding overlaps.
1556        That also fixes wrong TAF-key computations for key_1, key_2
1557        with bulf formulae.
1558      - exf_init.F modify #ifdef for exf_init_evap
1559      - exf_getffieldrec.F, ctrl_getrec.F
1560        The following INT-usages are not safe:
1561          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1562          fldcount = int(fldsecs/fldperiod) + 1
1563        and were modified.
1564    o autodiff: checkpoint_lev...
1565      - updated storing for bulk formulae (some arrays were missing)
1566      - added state for seaice package
1567      - synchronized with main branch
1568    o DIVA:
1569      Modif.s in
1570      - the_main_loop.F
1571      - the_model_main.F
1572      and added cost_final_restore.F cost_final_store.F
1573      o With these changes, it is possible to fully separate
1574        the first forward run to compute the cost function (mdthe_main_loop)
1575        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1576        into separate model executions.
1577        This enables better tuning of DIVA to given queue sizes.
1578      o Loss of cost function value in consecutive DIVA runs is
1579        fixed by storing to 'costfinal' file.
1580      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1581        beginning/end of adjoint integration is accounted for.
1582      The current changes apply to TAF-1.4.26.
1583      TAF has one remaining bug, requiring one manual change
1584      (see MITgcm manual).
1585    o cal: synchronized between MAIN and ecco-branch
1586    
1587    checkpoint48i_post
1588    o Changes to restore differentiability of code w.r.t. previous tag
1589      (mostly adding new routines to make list and replacing
1590      pressure by totPhiHyd).
1591    o Updated and merged grdchk package
1592      - has both ADM and TLM checks
1593      - works for single- and multi-proc.
1594      - output cleaned
1595      - worked successfully for parallel DIVA
1596    o genmake:
1597      - Adding -platform=SP4
1598      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1599    o Modif. for DIVA:
1600      ctrl_unpack should not be called in intermediate DIVA interval.
1601      (similar thing would apply for active files such as
1602      tbar, sbar, psbar, which should not be reinitialised;
1603      only relevant for ecco-branch)
1604    
1605    checkpoint48h_post
1606    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1607    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1608    o Added SEAICE_initialHEFF to pkg/seaice
1609    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1610    
1611    checkpoint48g_post
1612    --- EOS:
1613    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1614      store total Potential in totPhyHyd for diagnostics & EOS.
1615    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1616    --- Pressure/geopotential gradient:
1617    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1618    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1619      ( changes results of global_ocean_pressure )
1620    o NLFS + z-coord.: add eta*Rho' contribution.
1621    o accurate phiHyd when using interface-W at the middle between 2 centers
1622     ( changes results of ideal_2D_oce )
1623    o includes r* 2nd term in potential gradient.
1624    
1625    checkpoint48f_post
1626    Merging from release1_p12:
1627    o Modifications for using pkg/exf with pkg/seaice
1628      - improved description of the various forcing configurations
1629      - added basic radiation bulk formulae to pkg/exf
1630      - units/sign fix for evap computation in exf_getffields.F
1631      - updated verification/global_with_exf/results/output.txt
1632    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1633      (SBO) core products, including oceanic mass, center-of-mass,
1634      angular, and bottom pressure (see pkg/sbo/README.sbo).
1635    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1636      to avoid negative values in shallow regions.
1637      - updated verification/natl_box/results/output.txt
1638      - updated verification/lab_sea/results/output.txt
1639    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1640    o Added useSingleCpuIO option (see PARAMS.h).
1641    o Updated useSingleCpuIO option in mdsio_writefield.F to
1642      work with multi-field files, e.g., for single-file pickup.
1643    o pkg/seaice:
1644      - bug fix in growth.F: QNET for no shortwave case
1645      - added HeffFile for specifying initial sea-ice thickness
1646      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1647    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1648      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1649    o pkg/seaice:
1650      - adjoint-friendly modifications
1651      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1652    
1653    checkpoint48e_post
1654    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1655    o dynamics: change definition of computational domain & adapt mom_fluxform
1656      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1657    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1658        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1659        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1660        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1661        inverted_barometer solid-body.cs-32x32x1
1662      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1663    
1664    checkpoint48d_post
1665    o in preparation for r*:
1666     a) use pre-computed gradient of hydrostatic potential:
1667        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1668     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1669        => affects results of glob_oce_pressure (different truncation error)  
1670      update output.txt of ideal_2D_oce & global_ocean_pressure
1671    
1672    checkpoint48d_pre
1673    o in preparation for r*:
1674      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1675      pass the 2 comp. of the grad. as arguments to momentum S/R.
1676      but for the moment, only used if it does not change the results.
1677    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1678    
1679    checkpoint48c_post
1680    Modifications in treatment of initial flux forcing controls
1681    to avoid extra storing of flux fields.
1682    
1683    checkpoint48c_pre
1684    o Added tidal_basin_2d experiment (currently 1D!)
1685    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1686    
1687  checkpoint48b_post  checkpoint48b_post
1688  o r* coordinate added in #ifdef NONLIN_FRSURF block.  o r* coordinate added in #ifdef NONLIN_FRSURF block.
