4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
7      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
8      a maximum grid-scale Reynolds number.  Also, changes all length calculations
9      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
10      Suggested values of viscosity parameters found in mom_calc_visc.
11      Many new viscosity diagnostics available.
12    
13    checkpoint57s_post
14    o Add clearing-house for viscosity calculations, mom_calc_visc and
15      correct numerous bugs in LeithD and Smagorinsky discretizations.  
16      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
17      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
18      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
19      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
20      The Strain-Tension form is now called with useStrainTensonVisc=.true.
21      ViscAhStrain and viscAhTension are now retired.
22    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
23    o In response to JMC's bug report, genmake2 now ignores any soft-links
24      that it finds in the *current* directory when searching for files.
25      Soft-links found in any other source directories will still work as
26      they did before.
27    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
28      a C routine to unlimit the stack size
29    o mnc-ify pkg/aim snapshot vars
30    o mnc-ify pkg/land as requested by Daniel
31    o various changes to mnc including:
32      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
33      - output can now be grouped so that all files within a group
34          change the ITER portion of their names in lock-step together
35      - can now read ("global") PER-FACE (in addition to PER-TILE) files
36          and works with both EXCH1 and EXCH2 (but needs more testing)
37      - writing works for all verification test cases w/ g77 on Linux
38    
39    checkpoint57r_post
40    o make MNC variable initialization happen earlier
41    o add diagnostics for (almost) each term of the momentum Eq.
42    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
43    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
44    o remove MINIMAL_TAVE_OUTPUT option ;
45      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
46    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
47      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
48    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
49    o add time-dependent SST, SSS control
50    o cost terms in ecco/ modularized (new cost_generic.F)
51    o cost_averages routines are modularized (new cost_averagesgeneric.F)
52    o new infrastructure for seaice model vs. obs misfits in seaice/
53      * driver from the_main_loop.F is seaice_cost_driver.F
54      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
55      * gradient check in Exp. 6a of natl_box_adjoint/
56    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
57      (see README file)
58    
59    checkpoint57q_post
60    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
61    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
62      - bug was reported by Jean-Michel and Ian Fenty
63    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
64      update exp. cpl_aim+ocn output.
65    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
66      Needed for high-res. runs with large global files
67      to be able to limit tapelev size
68    o Changed some tests for adjoint:
69      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
70      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
71      * global_ocean.90x40x15/ back to default 3-level checkpointing
72    o Modifications to enable scripted COMMON to MODULE conversion
73      * verification/OpenAD/code/ has necessary scripts and description;
74      * converts, compiles and runs successfully;
75    
76    checkpoint57p_post
77    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
78    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
79      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
80    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
81    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
82      (was already the case for dissipation with mom_vecinv,
83       and also the case for grad.PhiHyd when staggered-timeStep)
84      This will allow to put dissipation out-off the AB time-stepping.
85     Unfortunately, affects truncation error. Update output of exp. that "fails"
86      (cg2d matching number) and leave the others for later: front_relax(10),
87      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
88      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
89    
90    checkpoint57o_post
91    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
92      (2) its ready to be documented during the 20050801 DocFest
93    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
94      for ideal_2D_oce and lab_sea on linux_ia32_g77
95    o set to #undef CTRL_SET_OLD_MAXCVARS_30
96      in global1x1_tot/code_seaice_adj to access indices 32, 33
97      (worth another tag)
98    
99    checkpoint57n_post
100    o adding precip control xx_precip 32
101    o adding swflux control xx_swflux 33
102    o Replacing 10 forcing penalty cost routines by 1 generic.
103    o Implementing partitioning in time-mean and variable adjustment
104      for atmos. state.
105    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
106    o in natl_box_adjoint:
107      * updated exp 1 to 10
108        (but does not have time-mean vs. variable split results yet)
109    o updated global1x1/*_seaice_adj/
110      to incorporate latest changes
111    o enable useSingleCpuIO for mdsio vector routines
112      (applies in particular to tapelev I/O)
113    o removed inefficient K-loop in all active_file*control*.F
114    
115    checkpoint57m_post
116    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
117      and advect_cs (use EXCH-2 and standard cs-32 grid files).
118    o pkg/exch2: filling of face-corner halo regions is optional
119      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
120    
121    checkpoint57l_post
122     tag before updating tutorials (pre-release-2)
123    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
124       for output and interpolation of input fields onto model grid)
125    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
126       Affects results of exp. rotating_tank ; update output.txt.
127    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
128          and taking the square quantity and/or using a fraction-weight field.
129    o fix aim_diagnostics_init.F mate numbers.
130    o add mnc output capability to diagnostics/diagstat and update
131      our cvsignore files for the ACSII output generated
132    
133    checkpoint57k_post
134    o lab_sea now uses diagnostics package and provides a suite of
135      new EXF diagnostics output.
136    
137    checkpoint57j_post
138    o exf
139      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
140        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
141        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
142      * extended diagnostics output
143        - now includes all EXF variables
144        - hs, hl moved to common block
145        - separate S/R for diagnostics, called after ctrl vector is added
146        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
147        - EXFqnet contains true Qnet (i.e. includes qsw)
148      * updated verif. lab_sea, global_with_exf
149      * Rearranging hflux (exf_mapfields -> exf_getforcing)
150        to ensure that diagnostics sees a true EXFqnet
151    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
152    o diagnostics pkg: change pointers so that 1 diagnostic can be used
153      several times with different frequencies.
154    o mnc-ify the thsice package as requested by Daniel Enderton
155      - the monitor--MNC output needs work
156      - many attributes need to be added (most are currently blank)
157    o mnc-ify theaim_v23 package as requested by Daniel Enderton
158      - many attributes need to be added (most are currently blank)
159    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
160    o add Sadourny like discretization to the 4th.O vorticity advection scheme
161    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
162      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
163         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
164    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
165     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
166    
167    checkpoint57i_post
168    o Diagnostics package was changed: diagnostic allocation is now deactivated
169      by setting an empty file name in the namelist (used to be by setting 0 frequency)
170    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
171      add 1rst Order upwind vertical Shear.
172    o add a quick fix for A/B checkpointing in OFFLINE mode
173    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
174      end-run around the C/Fortran linking horror in eesup/src/timers.F
175    o added pkg/runclock: allows user to terminate run based on wall clock
176    o added non-hydrostatic scaling parameter: nh_am2
177    o pkg/my82: futile attempt to make results compiler-independent by adding
178      some "_d 0", etc. no effect.
179    o for mnc output, fill the 'T' coordinate var with myTime and create a
180      separate 'iter' variable for iteration count
181    o pkg/diagnostics:
182      add new capability: output of Global/Regional & per-level statistics ;
183      tested against monitor output (including land & thSIce) on various exp.
184    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
185    
186    checkpoint57h_done
187      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
188      data.diagnostics, data.gchem, data.ptracers) is done.
189    
190    o pkg/diagnostics: prepare for Global/Regional statistics.
191      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
192    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
193      and rename it: DIFFERENT_MULTIPLE
194    
195    checkpoint57h_post
196    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
197    o pkg/diagnostics: change output frequency, now in seconds (instead
198      of Nb of iterations). This requires to change data.diagnostics.
199    checkpoint57h_pre
200    
201    o in mnc, let the user create the output dir if both mnc_outdir_date
202      and mnc_outdir_num are false
203    o add fflags() to pkg/diagnostics which allows one to specify, on a
204      per-file basis, the file precision [default behavior is unchanged]
205    o added diagnostics to pkg/kpp, including computation of mixed layer
206      depth based on a temperature/density criterion
207    o updated verification/natl_box to test the new pkg/kpp diagnostics
208    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
209    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
210    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
211      not mnc -- this mistake was found by JMC and is now corrected
212    
213    checkpoint57g_post
214    o add Adams-Bashforth 3rd Order time stepping:
215      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
216      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
217    checkpoint57g_pre
218    
219    o make lambda[Theta,Salt]ClimRelax spatially varying
220      (default remains spatially uniform constant based on tau)
221    o added new control variables
222      * init. uVel, vVel, etanN
223      * lambda[Theta,Salt]ClimRelax
224    o separate masks used for ctrl_pack/unpack 'from write_grid' output
225      (suggested by G. Forget)
226    
227    checkpoint57f_post
228    o add parameter "baseTime" = model base time = time at iteration zero
229      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
230      account for baseTime shift
231    o move Coriolis arrays from PARAMS.h to GRID.h
232    checkpoint57f_pre
233    
234    o mnc-ifying the seaice package
235    o introduced an alternative length scale calculation for use in the limiting
236      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
237    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
238    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
239      as well as grad(vort3).  Made it compatible with both approximate form
240      for the cubed sphere and full form of these gradients.  Added flag
241      useFullLeith to select between approximate and full form.  
242    o add "d0" in getcon.F to reduce differences between compilers/platforms
243      update output.txt of exp. fizhi-gridalt-hs
244    o change port_rand funtion to allow to set the seed.
245    o fix obscure MNC bug involving conversion between reals and integers
246      - it caused no problems with certain (eg. gcc, ifc) compilers but the
247        new version is now more standards-compliant
248    o adjoint-related modifications
249      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
250      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
251      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
252    
253    checkpoint57e_post
254    o Adding eddy stress controls a la Ferreira et al.
255    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
256    
257    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
258      update output.txt of exp. fizhi-gridalt-hs
259    o add more "Z" dimensions and associated coordinate vars to MNC
260    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
261    o parameter calendarDumps: when set, approximate months (30-31 days) and years
262      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
263      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
264      months and years.  Requires pkg/cal.
265    o diagnostics: add pickup functionality
266      - off by default for backwards compatibility
267      - current version only uses MDSIO -- MNC will be added
268    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
269    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
270    
271    checkpoint57d_post
272    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
273    o modify verification/ideal_2D_oce so that it tests the creation of mnc
274      output from the diagnostics package
275    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
276    o make genmake2 more portable by using ".$FS" instead of ".f" for more
277      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
278    o add coordinate variables to the MNC output from the diagnostics package
279    o change MNC-flags default value: true when useMNC=TRUE
280    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
281      the ability (off by default) to read the grid information using MNC
282    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
283    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
284    o do snap-shot diagnostics at the middle of the time-interval (instead of
285      at the end).
286    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
287      new test for AIM with thSIce + slab-ocean
288    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
289    o move state variable diagnostics to the beginning of the time step ;
290      (note: still needs some work specially for snap-shot diagnostics)
291      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
292    
293    checkpoint57c_post
294    o Change testing option (-ieee) to get closer agreement between g77 & ifort
295    o generate new output.txt files on faulks with g77 & the new -ieee option
296    checkpoint57c_pre
297    
298    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
299      update output.txt of exp. global_ocean.90x40x15
300    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
301      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
302    o add saltFlux(+File) forcing capability with periodicExternalForcing
303    o allow to use pkg diagnostics for GM-Redi & ThSIce output
304    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
305    o improvements for the MNC output from DIAGNOSTICS:
306      - correct handling of the unlimitied dimension
307      - all dims now have associated coordinate variables
308      - variables located at U, V, and Corner ("Z") points are now written
309        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
310        *all* data points are output
311    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
312    o added pkg/seaice/seaice_monitor.F
313    o mdsio_readfield.F can now read files visible only to master MPI process.
314    o pkg/seaice: some test code for ice-modified ocean stress
315    o exf_getffields interpolation defaults to bilinear for all scalar forcing
316      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
317      spurious negative numbers for precipitation and humidity.  Will cause
318      some small numerical differences for integrations using pkg/exf/exf_interp.F.
319    o pkg/ctrl/
320      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
321        May be enabled via doPackDiag
322      *  introduce z-scaling of
323         + gradient (doZscalePack) and
324         + control (doZscaleUnpack)
325    o pkg/mdsio/
326      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
327      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
328    
329    checkpoint57b_post
330    o simplify options in diagnostics_fill arguments (remove weird combinations)
331    o fix MNC coordinate variables so that they now contain per-face index
332      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
333      general, EXCH2 grids are only aligned to a "local" coordinate system
334    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
335    o Implement instantaneous output within pkg diagnostics:
336      setting a negative frequency in data.diagnostics produces
337     "snap-shot" output (as opposed to time-average if freq > 0)
338    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
339      NOTE: change ptracer diagnostics name: use 2 characters to work with
340            more than 9 tracers. Add also diagnostics of advect & diffus flux.
341    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
342      becomes the coordinate variable for the 'T' dimension
343    o add CF-style coordinate variables to MNC
344      - just a first cut:  numbers are meaningless on the cubesphere and
345        missing along the T axis but otherwise it works!
346    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
347    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
348    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
349      this is based directly on what the model compute, so that the content of
350      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
351    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
352    o clean up build options files for SunOS, in particular
353      - remove -traditional from xmakedepend
354      - change -xarch=v9 to -xarch=native for f77
355      - restore use of make (not gmake)
356      - add CC=gcc if using g77
357    o changes per discussion of AM, JMC, & EH3 today:
358      - move redundant "grid" variables out of "state" -- in preparation of
359        creating proper CF-style coordinate variables and in recognition
360        that any/all grid variables can be easily copied (eg. w/NCO) from
361        the grid files into any of the other NetCDF files
362      - *always* output grid variables with MDSIO (this will eventually be
363        changed)
364      - output MNC grid file if useMNC is true
365    o every instance of _END_MASTER() has been found and replaced with
366      _END_MASTER( myThid ) in order to satisfy certain picky Sun
367      preprocessors
368    o re-arrange diagnostics pkg initialisation:
369     - allow each package to extend the available diagnostics list
370     - add some checking and fix small problems (multi-threaded, ...)
371     - new S/R diagnostics_fill (replace fill_diagnostics):
372       look through the short list of active diag. (instead of the long list)
373       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
374    
375    checkpoint57a_post
376    o this set of changes restores TAMC compatibility
377      tested for global_ocean.90x40x15 adjoint on trough
378      (what a pain)
379    
380    checkpoint57a_pre
381    o some modifs in tools/build_options for sunos
382    o call ctrl_pack for ctrl at end for optimcycle=0
383    
384    checkpoint57
385    o add horizontal bi-harmonic viscosity for vertical velocity
386      - new parameter viscA4W (defaults to viscA4)
387      - affects only non-hydrostatic code
388      - to be done: no-slip lateral boundary conditions
389    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
390    o implement Implicit Vertical advection for pTracers
391    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
392      (implemented also for implicit vertical diffusion & advection)
393    o OBCS: extend application of tracer open boundary conditions
394      to a strip beyond the boundary of width Olx/Oly
395    o add call monitor to TAF set of required calls (flow directives)
396      and include in natl_box_adjoint
397    o untangle a few ifdefs related to cost, ctrl, autodiff
398      untangel a few ALLOW_ECCO_OPTIMIZATION
399    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
400      (theta2, salt2 in ecco_cost_weights)
401    
402    checkpoint56c_post
403    o OBCS as control variables
404      - update ctrl_ad_diff.list, obcs_ad_diff.list
405      - remove balance of obcs controls from default
406      - fix index bug nobcs in ctrl_init
407      - fix dummy fields filen in ctrl_pack
408      - add dummy weights for obcs
409    o lsopt: comment out fort.94 output
410    o optim:
411      - remove unnecessary header files
412      - adjusted namelists
413      - add xerbla.F to Makefile
414    o exf:
415      - multiple modifications of exf_check_range
416      - unit change in exf_init_runoff from [m/year] to [m/s]
417    o mdsio:
418      - i/o-vector change debugLevel from debLevA to debLevB
419    
420    checkpoint56b_post
421    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
422      is called from DO_THE_MODEL_IO
423      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
424      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
425      - clean up PTRACERS_WRITE_TIMEAVE a little
426    o add another verification experiment that tests both the cfc-pkg and
427      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
428      reactive tendencies treated inline with regular timestepping
429    o testreport previously did a lousy job of comparing small numbers, so
430      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
431      implemented in the little c-progam tmp_cmpnum.c which is embedded in
432      testreport.
433    o ptracers_monitor: bug fix for MPI
434    
435    checkpoint56a_post
436    o GCHEM: finish reorganizating the package
437      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
438        (introduces another 3D-array for each passive tracer, but only if
439        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
440        gchemTendency is not needed because the timestep is done separately)
441      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
442      - GCHEM is now---more or less cleanly---separate from PTRACERS
443      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
444        so clear to me how that should be done in a general way.
445    o CFC: improve formatting of output in CFC_ATMOS
446    o PTRACERS:
447      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
448        that ALL experiments with ptracers enable can be checked. This makes
449        GCHEM_MONITOR obsolete.
450      - include a runtime parameter PTRACERS_monitorFreq that defaults to
451        monitorFreq
452      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
453    o add PTRACERS (PTR0[1-5]) to testreport output
454    o exf_check_range:
455      * default changed to .TRUE.
456      * will check values for niter0 if debLevA, every timestep if debLevB
457      * STOP in exf_check_range if 'out of range'
458      * range chosen generous to allow for potential extema
459      TBD: a version with stricter range
460           permitted range would be runtime parameters
461    o GMredi:
462      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
463      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
464      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
465    o GCHEM:
466      - move call to GCHEM_FORCING_SEP, so that it is now called before
467        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
468      - introduced a useGCHEM runtime flag and applied it everywhere.
469      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
470        this flag is now only visible within GCHEM-pkg routines.
471      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
472        be replaced by a 3D array that is computed before thermodynamics; for
473        this, the tracer ID iTracer had to be included into the parameter list
474        of ptracers_forcing
475      - set up forward_step to call gchem_forcing, that will replace
476        gchem_forcing_int in ptracers_forcing
477      - cleaning up
478    o small cleaning of exch2: remove files that are also in eesupp/src
479    
480    checkpoint56
481    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
482    o mnc: cleanup "full" files--fixes out-of-memory problem
483    o ECCO-GODAE
484      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
485      * fully merged and updated from SIO code
486        windstress sign change affects
487        - exf_inscal_[u/v]stress
488        - sign of xx_tau[u/v] adjustments
489        - signs in cost_scat
490      * ctrl_get_gen: avoid update of tau[u/v] for first few days
491      * natl_box_adjoint updated and compressed
492      * 2-level checkpoint switch added
493        (tested in EXP. 1 of natl_box_adjoint)
494      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
495    o SVD
496      * first complete, non-hacked version for SVD calculations
497      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
498        performed via direct access files admtlm_vector.it????
499        (via ctrl_[un]pack)
500      * optimcycle is used for ARPACK iteration counter
501        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
502      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
503        and add linear transforms where necessary
504      * controls are initial/final SST, SSS (can be extended; need to check
505        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
506    o mdsio: filename info to both stderr, stdout
507    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
508      from sign change
509    
510    checkpoint55j_post
511    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
512      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
513    o add consistent build directories and .cvsignore files to verification
514    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
515    o make all subroutines 30 or less characters in length for certain older
516      compilers to work (a thorough search only turns up two routines in
517      pkg/ptracers)
518    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
519      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
520    
521    checkpoint55i_post
522    o change arrays for total vertical diffusivity (2.D if explicit,
523      3.D if implicit) ; each ptracer uses its own background value.
524    o added mnc/NetCDF output capability to ocn_compon_interf
525      - added bits to verification/cpl_aim+ocn so that it can run on
526        ITRDA and other clusters without the mpirun "-wd" option
527    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
528      configuration
529    o give MNC the ability to create additional files rather than
530      exceeding a specified file size limit "MNC_MAX_FILESIZE"
531      - the default is just less than 2GB which is a practical limit
532        on many systems
533    o Compute the non-local term using either KPP vertical diffusivity (=default)
534       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
535    
536    checkpoint55h_post
537    o add verification test "vermix"
538    o remove all the *_ioinc flags and replace with the single global
539      outputTypesInclusive flag
540    o allow to set a vertical profile of vertical diffusivity for T & S
541    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
542    o useMNC moved from data.mnc to data.pkg
543    
544    checkpoint55g_post
545    o Renaming carbon AD experiments to comply with testreport conventions
546    o Updating adjoint of Held-Suarez hs94.1x64x5
547    o Fixing directives for non-ECCO forward_step, after ECCO directives
548      have been fixed to avoid recomp. of do_oceanic_phys
549      Works well for global_ocean.90x40x15,
550      but recomp. issue remains for carbon
551    o Updating adjoint output for natl_box_adjoint after
552      pkg/ecco has been modified (see taga c55d_post)
553    
554    checkpoint55f_post
555    o rename to timeave_init_fixed
556    
557    checkpoint55e_post
558    o some delicate re-shuffle of store directives to avoid one
559      extra call of do_oceanic_physics
560      affects ecco_the_main_loop.F, do_oceanic_physics.F
561      checkpoint_lev1_directives.h
562    o NB: this may break global_ocean adjoint temporarily,
563      but it is clear how to fix it. Will do later, need this now.
564    
565    checkpoint55d_post
566    o ECCO specific cost function terms (up-to-date with 1x1 runs)
567    o ecco_cost_weights is modified to 1x1 runs
568    o modifs to allow observations to be read in as
569      single file or yearly files
570    o enable to read exf forcing fields as either
571      single file or yearly files (flag useExfYearlyFields)
572    checkpoint55d_pre
573    
574    o switch between 2-level and 3-level checkpointing
575    o add ability of MNC to write local and "partial" (eg. 2D slices where
576      the full 3D field is never actually stored) arrays to NetCDF files
577      with the correct (that is, the complete multi-dimensional) set of
578      array indicies
579      - used in mom_vecinv() to write the diagFreq output
580      - tested (demonstrated) in verification/aim.5l_cs
581    o further mnc-ification
582      - add verification/lab_sea to the list with mnc setups
583      - fix undefined mnc v-names in cd_code
584      - add kpp to mnc output (both snapshot and timeave)
585    o non-hydrostatic code
586      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
587        in calc_gw.F
588      - defaults to viscAh
589      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
590        friction or Leith) in non-hydrostatic mode, as long as there is
591        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
592    o pkg/cost
593      extend simple cost functions to treat time mean quantities
594      (T,U,V) via cost_accumulate_state from cost_tile
595    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
596        be 2 times larger than the minimum size the advection scheme requires.
597        now get a perfect conservation of salt in advect_cs test-exp (updated)
598    o GGL90 (Gaspar's TKE mixed layer)
599      - add horizontal diffusion of TKE, requires exchanges in
600        do_fields_blocking_exchanges, horizontal diffusivity is zero by
601        default. In OPA there is no horizontal diffusion of TKE but the
602        mixing coefficients are computed from a horizontal average of TKE of
603        6 points or so. I think that diffusion has a little more physical
604        justification.
605      - clean up ggl90_calc in the hope of reducing memory usage (this hope
606        was in vain)
607      - mask tke-variable in ggl90_init
608    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
609    o fix biharmonic diffusion on CS-grid.
610    o more obcs stuff
611      - added obcs_external_fields_load as an alternative to the EXF-pkg option
612        for reading boundary values. This routine is called from
613        obcs_prescribe_read
614      - updated obcs_check
615      - changed sponge layer relaxation parameter units for days to seconds
616      - turned off sponge layer by default
617      - changed argument list of OBCS_CALC to myTime+deltaTclock
618      - fixed about 35 bugs in obcs_external_fields_load
619    
620    checkpoint55c_post
621    o obcs stuff
622      - new runtime flags useOBCSprescribe, useOBCSbalance
623      - re-arranged obcs_calc
624      - moved exf_getobcs to obcs_prescibe_read
625        obcs_prescibe_read is called after ORLANSKI stuff
626        and independent of it (executable can contain all).
627      - updated obcs_check
628      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
629        These may be necessary only if tangential velocities are
630        prescribed at OB, not sure, needs testing.
631    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
632      which simplifies the calls and passes the ifc check-bounds test
633    
634    checkpoint55b_post
635    o add a 2D scalar, Z location, exchange_2 routine.
636    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
637      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
638      affects advect_cs results (for the wrong reason): update output.txt
639    o use a more standard discretization for biharmonic viscosity ;
640     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
641      affects results of dome set-up: update output.txt
642    o fix gad_advection.F (CubedSphere part), back to version 1.23
643    o fix bug in mom_vi_del2uv.F (CubedSphere part).
644    
645    checkpoint55a_post
646    o merged code to
647      * prescribe/read time-dependent open boundaries
648        (works in conjunction with exf, cal)
649      * sponge layer code for open boundaries
650      * each boundary N/S/E/W now has its own CPP option
651        (healthy for the adjoint)
652    
653    checkpoint55
654    o up-to-date adjoint of previous breaks
655      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
656      - global_ocean_ebm: adjoint still needs fix (TLM ok)
657      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
658      - carbon: * remove tr1-related adjoint verification
659                * add ptracer as control variable
660    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
661      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
662    
663    checkpoint54f_post
664    o in verification/carbin/ remove experiment related to
665      ALLOW_PASSIVE_TRACER (array tr1 etc)
666      code_ad/ input_ad/ results_ad
667    
668    o add two new packages
669      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
670        + subject to optimization (memory)
671      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
672        + subject to reordering (many GOTOs in the original code)
673        + so far opps is called for every (i,j) point, and then operates in
674          the vertical; one may want to reorder the scheme in order operate in
675          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
676          fields)
677    o overhaul of IO so that we now have flags for MDSIO and/or MNC
678      - all verification tests compile and run with linux_ia32_g77
679      - defaults are compatible with current input files--nothing
680        should change if you were not previously using MNC
681      - MNC output has been added in numerous places (eg. timeave)
682        but there are still a few writes not yet do-able with MNC
683        (this is in progress)
684      - flags now allow for either/or/both use of MDSIO and MNC and
685        documentation will soon follow
686      - numerous small formatting cleanups for ProTeX
687    o add version info (via BUILD_INFO.h) to MNC and stdout
688    
689    checkpoint54e_post
690    o add two new packages
691      - pp81 (Packanowski and Philander, 1981), Richardson number and
692        stratification dependent mixing
693      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
694      - these scheme operate in a similar manner as KPP (without ghat, of
695        course), however there is only one diffusivity that is used for both
696        temperature and salinity (and passive tracers)ç
697    o add offline package
698    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
699      provided by Stephanie Dutkiewicz
700    o genmake2: add ability to search for C compilers and cleanup test output
701      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
702    
703    checkpoint54d_post
704    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
705    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
706      leading to additional shift by 5 days each year of integration
707       (i.e. leading to considerable offset over the years)
708    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
709    o start with no AB and no initial filtering (staggerTimeStep):
710      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
711    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
712      (external loading & cpl import/export stay in forward_step.F)
713    o update coupling interface to work with new staggerTimeStep
714    o change MDSIO ptracers_pickup.
715    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
716    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
717    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
718    
719    checkpoint54c_post
720    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
721      this affects (truncation error) output.txt of test-exp:
722       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
723    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
724    o change Qnet to always be the net heat flux, (+upward).
725      affects (truncation error) output of natl_box exp.: updated
726    o define the max number of passive tracers in PTRACERS_SIZE.h
727    o start to test mnc routinely in exp0
728    o add sea-ice loading (sIceLoad) as a new forcing field.
729    
730    checkpoint54b_post
731    o add testreport "-j JOBS" option for parallel builds (tested and pretty
732       impressive on Altix and Opteron systems)
733    o diagnostics can now write NetCDF files through the mnc package
734    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
735    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
736    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
737      affects (truncation error) output of lab_sea & natl_box exp.: updated
738    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
739    
740    checkpoint54a_post
741    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
742    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
743    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
744    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
745      + internal_wave (shift in writing cg2d_ini_res)
746    checkpoint54a_pre
747    
748    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
749      - modified verification/lab_sea and natl_box_adjoint accordingly
750    
751    checkpoint54
752    checkpoint53g_post
753    o prepare splitting of thermodynamics: store convect.counter in common block
754    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
755      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
756    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
757    o new parameter "nShapS": allow to treat differently S from T (nShapT)
758    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
759    o restore adjointability
760    
761    checkpoint53f_post
762    o modifications that affect AIM experiment results (update output.txt):
763      - no advection of S at top interface Nr (pkg/generic_advdiff)
764      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
765    o AIM pkg:
766      - include stability function into surf.Flux derivative relative to Tsurf
767      - calculate clear-sky radiation & surface temp. change (for diagnostics)
768    
769    checkpoint53e_post
770    o merged cylindrical coord configuration
771    o added rotating_tank experiment
772    checkpoint53e_pre
773    
774    checkpoint53d_post
775    o faulks upgraded: re-generate output.txt that have changed:
776       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
777    o Added Bryan and Lewis, 1979, vertical diffusivity profile
778    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
779    o added Sadourny discretization of Coriolis
780      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
781      - re-enabled use of omega3 (useAbsVorticity)
782    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
783      vector-invariant equations
784      - note: does *NOT* yet use same variable visc. for no-slip BC's.
785    o recoded the lateral boundary conditions for non-hydrostatic w, this time
786      hopefully without new bugs
787      - still to do: biharmonic friction for non-hydrostatic w
788    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
789    o regenerated output for global_ocean_ebm (using -ieee)
790    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
791      of mom_common/
792      - simple re-arrangement of instructions within computing loop
793    checkpoint53d_pre
794    
795    checkpoint53c_post
796    o new version of coupler for AIM+thSIce and Ocean models
797     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
798     - land: change Evaporation of snow
799     - aim with thSIce: fix bug in snow-precip.
800    o changes to calc_gw.F
801     - bug fix for w^2 term near the bottom boundary
802     - (hopefully) improve the lateral slip boundary condtions for use with
803        partial/looped cells
804      - because the bug fix changes two verification experiments anyway (exp5
805        and plume on slope), change the lateral boundary condition from half slip
806        to the value of no_slip_sides
807    o ebm package wasnt quite up to the parallel task. Fixed that.
808    o Adjoint of EBM package + verification
809      * TLM OK
810      * ADM not sufficient accuracy yet (needs further testing)
811    
812    checkpoint53b_post
813    o Commiting new energy balance model to repository
814      * package is pkg/ebm
815      * verif. is verification/global_ocean_ebm
816      * references are in ebm_driver.F
817    C      * X. Wang, P. Stone and J. Marotzke, 1999:
818    C        Global thermohaline circulation. Part I:
819    C        Sensitivity to atmospheric moisture transport.
820    C        J. Climate 12(1), 71-82
821    C      * X. Wang, P. Stone and J. Marotzke, 1999:
822    C        Global thermohaline circulation. Part II:
823    C        Sensitivity with interactive transport.

825    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
826    C        Destabilization of the thermohaline circulation
827    C        by atmospheric eddy transports.
828    C        J. Climate 7(12), 1870-1882
829    o Will need long integration testing.
830    checkpoint53b_pre
831    
832    o created pkg/mom_common in preparation for variable viscosity code
833    o renamed and split ini_mnc_io
834    o pkg/land: only liquid water can diffuse or run-off
835    o AIM using land: soil wetness availability account for snow
836    o added printMapIncludesZeros to EEPARMS namelist
837    
838    checkpoint53a_post
839    o restore TAMC compatiility for exf_constants.h
840      (no usage of _d in .h)
841    o Additional storing in KPP in an attempt to fix
842      TAMC problem with adjoint of KPP code.
843      (no success...)
844      Identical code works fine with TAF.
845    o Fixed verification/natl_box_adjoint experiments.
846      Initial conditions for Experiments 4 and 5 are now
847      set to "SEAICE_initialHEFF=0", which is more reasonable,
848      and hence gives results closer to that of Experiment 2.
849      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
850    
851    checkpoint53
852    o stable checkpoint with up to date adjoint
853      TLM tests only run for 1st grdchk at the moment. Its unclear if
854      this is a code problem or a problem with resetting code for g_
855      variables that is being autogenerated wrong.
856      Otherwise:
857       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
858       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
859         are both still in chaos following their security messes.
860    
861    checkpoint52n_post
862    o various build (mostly genmake2) changes including:
863      - ability to build/run more easily within Cygwin and MacOS X
864      - more complicated Makefiles with a stronger dependence on Gnu Make
865    o pkg/seaice modifications
866      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
867        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
868        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
869      - changed proxy for geostrophic velocity and updated
870        verification/lab_sea/results/* accordingly
871      - removed ADI dynamic solver from pkg/seaice
872      - replaced all occurrences of 1/CSTICE or 1/CSUICE
873        they caused a segmentation fault under certain circumstances
874      - removed unused field WATR
875    o bug fix in exf-package:
876      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
877         now reflect that.
878    o small fixes in the cal-package:
879      - set reference date to first of January for the 'model'-calendar
880      - failing of cal_CheckDate in cal_FullDate now actually results in a
881        warning
882    o small modifications in exf-package to increase flexibility:
883      - change climtempfreeze from a constant to a runtime parameter that
884        is specified in data.exf_clim (default = -1.9)
885      - introduce runtime parameter windstressmax (default = 2.0) that is
886        specified in data.exf
887    o fix in pkg/thsice:
888      - update Evap (Tsf changes) to be consistent with Latent heat flux
889      - maintain snow precipitation unchanged (even if Tsf >=0).
890     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
891    
892    checkpoint52m_post
893    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
894      this does not change any of the results, because myIter=0 in swfrac always
895      lead to jwtype=2 (the default anyway), but the call makes little sense
896      as a default
897    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
898    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
899      atmospheric model (AIM) to use it ; add a "slab ocean" component.
900    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
901    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
902    o extending useSingleCpuIO option to work with new exch2 I/O format
903      - old-style, missing-tile I/O is still accessible by defining CPP
904        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
905    o monitor package can write to NetCDF files and/or STDOUT
906    o fix re-definition bug in MNC_GRID_INIT_ALL()
907    o doc/api_reference added
908      - a framework for building an API Reference Manual using all
909        the "protex" comments embedded in the code
910      - see pkg/generic_advdiff, pkg/mnc for examples
911    o MNC:
912      - make myThid the last argument for all subroutines
913      - new default for the grid files: NO halos
914      - add useMNC and other run-time flags
915      - separate per-file-group handling of the unlimited dimension
916      - early initialization of MNC w/ flags read at the eeboot stage
917        and lookup tables set in initialize_fixed
918      - write all MNC output to a freshly-created directory
919    o thermodynamics sea-ice (thsice) is now tested with testreport.
920    o test exp. advect_cs: use the standard cs32 grid ; update output.
921    o Added functionality to grdchk:
922      pick global i,j,k position (or nearest wet) where to perform check.
923    
924    checkpoint52l_post
925    o new land formulation:
926      a) use ground enthalpy as prognostic variable to ensure exact
927         energy conservation.
928      b) account for water temperature and for latent heat of freezing
929         in all processes (rain, run-off, ground storage)
930      c) compute surface and ground temperature implicitly.
931    o aim_v23 modification for new land model:
932      a) Treat separately land / ocean / sea-ice surface fluxes
933         to allow implicit computation of land & sea-ice surface temp.
934      b) add snow precipitation.
935    checkpoint52l_pre
936    
937    o fix problem (when 1 tile is empty) in min/max monitor.
938    o fix bug in timeAve (u,vZetatave in common block)
939    o no restoring terms under ice for pkg/seaice
940    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
941    o bug fix for pkg/seaice pickups
942    o change MNC call locations and add coordinate attributes
943    o mask vorticity at the corner ; affects global_ocean.cs output
944    o fix ini_curvilinear_grid ; test CS experiments with mpi
945    o aim.5l_cs: modify sea-ice fraction input file ; update output
946    o exf: Adding simple range check routine for exf fields after read
947    
948    checkpoint52k_post
949    o removed top-level directory "diags"
950      - we migrated these functions to pkg/timeave a long time ago
951    o fixed bug introduced in pkg/monitor
952    o accuracy ctrlprec = 32 insuffient for gradient checks using
953      averaged fields (I/O via cost_averages)
954      -> use ctrl.h in active_file*.F to control I/O precision.
955    o paramter list of CALL ADTHE_MAIN_LOOP
956    o added initial do_the_model_io to ecco
957    o set all ...Freq to zero after cost_final
958      taveFreq, dumpFreq, pChkptFreq
959    o MAIN and ECCO differentiability restored
960    
961    checkpoint52j_post
962    o fix nchklev in tamc.h for global_ocean...
963    o Bringing flow and store directives up-to-date
964    o Really weird thing!
965      call do_the_model_io from the_main_loop with parameters
966      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
967      TAF places a faulty re-call of initialise_varia
968      after cost_final call which should not be there!
969    checkpoint52j_pre
970    
971    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
972      error messages
973    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
974    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
975      debug output
976    o modfied mdsio_writefield.F to handle non-global files under exch2
977    o update AIM Cubed-Sphere exp (aim.5l_cs):
978      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
979    o update AIM Equatorial Channel exp:
980      use standard aim_v23 pkg and change the SST fields to be more realistic.
981    o globalFile now works with exch2
982    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
983      mon_vort3.F to make exch2 friendly with >1 tile per cube face
984    o limit timeave output for hi-res integrations
985    
986    checkpoint52i_post
987    o removed CPP_EEOPTIONS.h from verification/*/code
988    o updated the tiling for global_ocean_pressure
989    checkpoint52i_pre
990    
991    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
992      the old pkg/aim).
993    
994    checkpoint52h_pre
995    o shortened offending lines in exch2_send_rx?.template
996    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
997    o genmake2: add build & execute test for NetCDF code
998    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
999      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1000    o added useSingleCPUIO flag to monitor.F and mon_out.F
1001    o added temporary hack for sea-ice dynamics on the cube:
1002      metric terms are ignored and it is assumed that
1003      there is no sea-ice on cube faces 1, 2, 4, and 5.
1004    
1005    checkpoint52f_post
1006    o added exch2 cube routines to pkg/exch2
1007    o modified hs94.cs-32x32x5 to use it
1008    o added new grid files to hs94.cs-32x32x5
1009    checkpoint52f_pre
1010    
1011    checkpoint52e_post
1012    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1013      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1014    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1015      to work with implicit vertical advection and AB ;
1016    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1017    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1018     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1019    checkpoint52e_pre
1020    
1021    o fix bug in impldiff when Nr=1 or Nr=2.
1022    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1023    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1024    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1025      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1026    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1027    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1028    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1029    
1030    checkpoint52d_post
1031    o re-tiled many expts to allow comparison in multi-processor mode
1032      - updated output accordingly
1033      - changed hs94.128x64x5 to use intial T from file rather than use the
1034        random number generator
1035    o add infrastructure in model routines for fizhi and gridalt packages
1036    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1037    o changes to permit hi-res, cubed-sphere, configuration
1038      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1039      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1040      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1041        of surface winds for the cube
1042      (A verification experiment, based on global_ocean.cs32x15, but with
1043       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1044       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1045       complete with example surface forcing files and matlab scripts to look
1046       at the output and compare it with that of global_ocean.cs32x15.)
1047    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1048       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1049       to conform to the common rule.
1050    o check-in the first version of the coupler + interfaces for multi-components
1051       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1052       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1053       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1054       - ocean and atmos. share the same horizontal grid (no interpolation).
1055       - exchanges between component and coupler is done in forward_step
1056    o new verification experiment, cpl_aim+ocn:
1057       coupled ocean - AIM atmosphere on cs32 grid.
1058    
1059    checkpoint52d_pre
1060    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1061    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1062    
1063    checkpoint52c_post
1064    o Fixing OPTIONS files for use of exf:
1065      - ALLOW_ECCO not needed
1066      - ECCO_CPPOPTIONS.h should not be included from
1067        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1068        as has been the case in the past
1069      - All cal/exf related options are currently set in
1070        single header file. Should remain so until we
1071        agree on a consistent new policy.
1072    o Removed all CPP options for cal package.
1073      cal has no more CPP options.
1074    o modified STOREs in GAD_ADVECTION
1075    o corrected key comp. for passkey
1076    
1077    checkpoint52b_post
1078    o new version: "thsice" of thermodynamic sea-ice pkg:
1079     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1080     - modify fluxes but do not change theta directly;
1081     - light cleaning of bulk_force pkg (still needed with thsice).
1082     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1083       + output_thsice.txt to test thsice & bulk_force pkgs.
1084    o put back grid & coriolis monitor output.
1085    checkpoint52b_pre
1086    
1087    o call "do_the_model_io" at the beginning (=> dump initial state)
1088    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1089    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1090      (need info on NUMBER_OF_PTRACERS)
1091    o missing PTRACERS headers in some routines
1092    o default tamc.h in pkg/autodiff supposed to crash
1093      to ensure proper customization
1094    
1095    checkpoint52a_post
1096    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1097      - moved surfaceTendencyTice from pkg/seaice to main code
1098      - subroutine FREEZE_SURFACE now limits only surface temperature
1099        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1100        => new output.txt for global_ocean.cs32x15 & global_with_exf
1101      - keep the old version of FREEZE for backward compatibility;
1102        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1103      - corresponding modifs for TAF directives
1104    o added surface flux output variables to TIMEAVE_STATVARS
1105    o time-averaged output for pkg/ptracers
1106    o fix problem with ECCO-related divided adjoint
1107      snapshot file was missing some ad-variables,
1108      but no warning issued by TAF
1109    
1110    checkpoint52a_pre
1111    o some bug fixes for #undef REAL4_IS_SLOW
1112    
1113    checkpoint52 = ecco_c52_e35
1114    o after testing adjoints of checkpoint51u_post
1115    
1116    checkpoint51u_post
1117    o this is the post-merge tag of the ecco-branch
1118      (needs another clean checkout and re-testing)
1119    o various natl_box_adjoint configs and results
1120      but no input fields
1121    o obcs adjoint not yet merged!
1122    o adding ECCO global 1x1 and 2x2 degree configs
1123    o updated/extended some store directives for seaice
1124    o pkg/ecco now containes ecco-specific part of cost function
1125    o top level routines the_main_loop, forward_step
1126      supersede those in model/src/
1127      previous input data.cost now in data.ecco
1128      (new namelist ecco_cost_nml)
1129    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1130    
1131    checkpoint51t_post
1132    o this is the pre-merge tag of the ecco-branch
1133    
1134    checkpoint51s_post
1135    o cleanup: removed various obsolete #define-s
1136    o pkg/grdchk
1137      - renamed 'ph-grd 3' to 'grad-res'
1138      - merged from ecco-branch
1139        (remaining bug fixes for obcs gradient checks)
1140      - additional high-precision output for testreport
1141        (grep for 'precision_grdchk_result')
1142    
1143    checkpoint51r_post
1144    o cleaned up or removed CPP_OPTIONS.h files
1145    o updated results for some of the tests to reflect the new
1146      optfiles (-ieee: -O0 instead of -O3)
1147    
1148    checkpoint51q_post
1149    o cd_code:
1150      - moved cd_scheme.F -> cd_code_scheme.F
1151      - separate read_checkpoint from cd_code_ini_vars.F
1152      - separated cd_code part from write_checkpoint
1153      - updated AD_SOURCE, generated .flow
1154      - added CD_CODE_VARS.h to the_main_loop

1160        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1161      - confined inclusion of AD_CONFIG.h to where necessary.
1162    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1163    
1164    checkpoint51p_post
1165    o create initial cd_code package
1166      - WARNING: the initialization of fields within packages
1167        is broken because INI_FIELDS (where READ_CHECKPOINT is
1168        called) is called *before* PACKAGES_INIT_VARIABLES.
1169        This seems to be backwards since
1170        1) its important to initially zero the entire field including
1171           the "halo" region
1172        2) zeroing needs to be done *before* reading pickup info
1173           and the pickup call might or might not happen in any
1174           particular run
1175      - this needs an overhaul for R2
1176    o cleanup verification/*/code/GMREDI_OPTIONS.h
1177    o cleanup testreport
1178    
1179    checkpoint51o_post

1187    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1188    o bug fix in find_alpha.F for MDJWF:
1189      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1190        change rho -> rho-rhoConst
1191      - replace call find_rho to find_rhonum

1193      and shifted to thermodynamics
1194    o removed PTRACERS.h in ptracers routine
1195    o added surfacetendencyPtr to S/R parameter list pracers_forcing

1210      - moved surfaceTendencyTice from pkg/seaice to main code
1211      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1212      - subroutine FREEZE now limits only surface temperature
1213        (this means new output.txt for global_ocean.90x40x15,
1214         global_ocean.cs32x15, and global_with_exf)
1215    o added surface flux output variables to TIMEAVE_STATVARS

1264    o Moving pkg-specific flow directives to corresponding pkg
1265      Moving pkg-specific differentiation list to corresponding pkg
1266      Moving pkg-specific checkpoint-lev storing to corresponding pkg
1267      ---> conventions are
1268           - pkg_ad.flow

1270           - pkg_ad_check_lev?_dir.h
1271    
1272    checkpoint51i_post

1304    o Added on-the-fly spatial interpolation capability
1305        "USE_EXF_INTERPOLATION" to pkg/exf.
1306      - This is a temporary Cartesian-grid hack until
1307        the super-duper ESMF coupler becomes available.
1308      - See verification/global_with_exf/README for usage example.
1309      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
1310        flags and modified pkg/seaice accordingly.
1311    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
1312        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
1313        non-local transport term.
1314    
1315    checkpoint51e_post
1316    o pkg/mom_vecinv:
1317      - changes related to hFac: use S/R from aim.5l_cs/code (coriolis & vort.advec)
1318      - add time-ave diagnostic of vorticity advection.

1323    o AIM : add stratospheric drag in the upper level
1324    
1325    checkpoint51d_post
1326    o change function ILNBLNK (=> last non-blank char.) to return zero
1327      (instead of the string length) when the string. char is empty
1328    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
1329    o modif's to restore TAMC compatibility
1330      - avoid "_d" constructs in PARAMETER declarations
1331      - avoid interrupting lines by comment lines
1332    o Use cluster local disks for purely local I/O
1333      vs. globally visible disks needed for ctrl stuff
1334      (merged from ecco-branch)
1335      - new active_file_loc... and mdsio_..._loc routines
1336      - affected packages: autodiff, ctrl, grdchk, mdsio
1337    
1338    checkpoint51c_post
1339    o introducing integer flag debugLevel
1340      - debLevZero: suppress all output
1341      - debLevA: standard
1342      - debLevB: equivalent to current debugMode=.TRUE.
1343    o introducing pathname variable mdsioLocalDir for mdsio
1344      that can be specified at runtime
1345      (relevant for cluster I/O to local disk)
1346    `
1347    >>>checkpoint51b_post
1348    adjoint of ptracers
1349    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
1350    o extended state in checkpoint_lev?, etc.
1351    o alternative ctrl/cost with tr1 or ptracer
1352    o new comlev1_bibj_ptracers
1353    o new ptracers.flow
1354    o made ptracers_forcing same as external_forcing_s
1355    o added verification for adjoint with ptracers
1356      - adm. grdchk fail so far
1357      - tlm. grdchk OK
1358      - checked tapelev/comlev recomputations: OK
1359    <<<checkpoint51b_pre
1360    
1361    checkpoint51a_post
1362    o added code for biogeochemistry package
1363      - new pkgs: dic, gchem
1364      - new subroutine in ptracers
1365    o modify code for biogeo packages
1366      - in model/src and pkg/ptracers
1367    
1368    checkpoint51
1369    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1370      - autodiff, ctrl, exf, grdchk, seaice
1371      kept separate packages
1372      - cost, ecco, obcs
1373    o updating verification/internal_wave, verification/lab_sea
1374      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1375    
1376    checkpoint50i_post
1377    o Preparing next differentiable checkpoint and sync
1378      of MAIN vs. ecco-branch
1379      - 1st step: this one is differentiable
1380      - 2nd step: next(! not this) checkpoint will have updated packages
1381                  from ecco-branch)
1382    
1383    checkpoint50h_post
1384    o new package "land": provide surface BC for AIM.
1385    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1386    o AIM: use true log-P extrapolation for near surface temp (= as in
1387        F.Molteni paper) ; update aim.5l_cs output.
1388    o New variable in PARM03 for more flexible pickups
1389    o somewhat cleaned package initialisation sequence for
1390      ctrl/ cost/ ecco/ in packages_... routines
1391    
1392    checkpoint50g_post
1393    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1394      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1395      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1396        made the default because of faster convergence than ADI
1397    
1398    checkpoint50f_post
1399    o exf totally restructured
1400      - replaced all exf_set_ routines by one generic exf_set_gen.F
1401        and made sure it's still differentiable
1402      - split exf_getffields.F into new exf_bulkformulae.F
1403      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1404      - updated adjoint/makefile and relevant verif. accordingly
1405    
1406    checkpoint50f_pre
1407     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
1408          + change Evap over land. (update aim.5l_cs output)
1409     o added missing .cvsignores and made uniform across expts
1410     o changed configuration of tidal_basin_2d expt
1411     o added pkg/debug functions for tracing code in fatal crashes
1412     o tidied pkg/monitor to use MONITOR_OPTIONS.h

1414     o removed lots of single quotes from comments
1415    
1416    checkpoint50e_post
1417    o make KPP work with PTRACERS
1418     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1419       nearly a copy of kpp_transport_s
1420     - there is no analogue to SurfaceTendencyS, so I have to use
1421       gPtr(of the surface layer) instead
1422    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1423    checkpoint50e_pre
1424    
1425    checkpoint50d_post
1426    o change kpp output from multiple-record state files to single-record state
1427      files analogous to write_state.F
1428    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1429      analogous to the cg2d-related output.
1430    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1431      so that writing to internal file fn (with length 512) fails.
1432    checkpoint50d_pre
1433    
1434    checkpoint50c_post
1435    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1436    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1437    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1438    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1439    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1440    
1441    checkpoint50c_pre
1442    Merging from release1_p13:
1443    o bug fix for pkg/seaice dynamic solver
1444    o Added SEAICE_initialHEFF to pkg/seaice
1445    
1446    checkpoint50b_post
1447    o store u*,v* in gU,V instead of in guNm1,gvNm1
1448    o in order to put the momForcing out of the Adams-Bashforth:
1449      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1450      to timestep.F
1451    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1452    o re-generate output for highly sensitive test-exp:
1453       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1454    
1455    checkpoint50b_pre
1456    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1457    o corrected CPP option mismatch in exf_Bulk... functions for case
1458      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1459    
1460    checkpoint50a_post
1461    o Bug fix for merging between c50 and KPP.
1462      ikey was passed from thermodynamics to kpp_calc via
1463      common block rather than being recomputed in kpp_calc,
1464      in contradiction with new key itdkey.
1465      New key ikppkey created, and tamc.h headers updated.
1466    
1467    checkpoint50
1468    - 2nd step of merge with ecco-branch:
1469      merge changes in ecco-branch back into main trunk
1470    - bug fix in find_alpha
1471    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1472    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1473    - merged some sliced AD support routines
1474    
1475    checkpoint49
1476    merged from ecco-branch:
1477    o exf:
1478      - Enable initialisation of forcing fields to constant
1479        (runtime) values.
1480      - in exf_getffields.F
1481        Reduce i-/j-loop to interior domain, discarding overlaps.
1482        That also fixes wrong TAF-key computations for key_1, key_2
1483        with bulf formulae.
1484      - exf_init.F modify #ifdef for exf_init_evap
1485      - exf_getffieldrec.F, ctrl_getrec.F
1486        The following INT-usages are not safe:
1487          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1488          fldcount = int(fldsecs/fldperiod) + 1
1489        and were modified.
1490    o autodiff: checkpoint_lev...
1491      - updated storing for bulk formulae (some arrays were missing)
1492      - added state for seaice package
1493      - synchronized with main branch
1494    o DIVA:
1495      Modif.s in
1496      - the_main_loop.F
1497      - the_model_main.F
1498      and added cost_final_restore.F cost_final_store.F
1499      o With these changes, it is possible to fully separate
1500        the first forward run to compute the cost function (mdthe_main_loop)
1501        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1502        into separate model executions.
1503        This enables better tuning of DIVA to given queue sizes.
1504      o Loss of cost function value in consecutive DIVA runs is
1505        fixed by storing to 'costfinal' file.
1506      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1507        beginning/end of adjoint integration is accounted for.
1508      The current changes apply to TAF-1.4.26.
1509      TAF has one remaining bug, requiring one manual change
1510      (see MITgcm manual).
1511    o cal: synchronized between MAIN and ecco-branch
1512    
1513    checkpoint48i_post
1514    o Changes to restore differentiability of code w.r.t. previous tag
1515      (mostly adding new routines to make list and replacing
1516      pressure by totPhiHyd).
1517    o Updated and merged grdchk package
1518      - has both ADM and TLM checks
1519      - works for single- and multi-proc.
1520      - output cleaned
1521      - worked successfully for parallel DIVA
1522    o genmake:
1523      - Adding -platform=SP4
1524      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1525    o Modif. for DIVA:
1526      ctrl_unpack should not be called in intermediate DIVA interval.
1527      (similar thing would apply for active files such as
1528      tbar, sbar, psbar, which should not be reinitialised;
1529      only relevant for ecco-branch)
1530    
1531    checkpoint48h_post
1532    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1533    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1534    o Added SEAICE_initialHEFF to pkg/seaice
1535    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1536    
1537    checkpoint48g_post
1538    --- EOS:
1539    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1540      store total Potential in totPhyHyd for diagnostics & EOS.
1541    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1542    --- Pressure/geopotential gradient:
1543    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1544    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1545      ( changes results of global_ocean_pressure )
1546    o NLFS + z-coord.: add eta*Rho' contribution.
1547    o accurate phiHyd when using interface-W at the middle between 2 centers
1548     ( changes results of ideal_2D_oce )
1549    o includes r* 2nd term in potential gradient.
1550    
1551    checkpoint48f_post
1552    Merging from release1_p12:
1553    o Modifications for using pkg/exf with pkg/seaice
1554      - improved description of the various forcing configurations
1555      - added basic radiation bulk formulae to pkg/exf
1556      - units/sign fix for evap computation in exf_getffields.F
1557      - updated verification/global_with_exf/results/output.txt
1558    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1559      (SBO) core products, including oceanic mass, center-of-mass,
1560      angular, and bottom pressure (see pkg/sbo/README.sbo).
1561    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1562      to avoid negative values in shallow regions.
1563      - updated verification/natl_box/results/output.txt
1564      - updated verification/lab_sea/results/output.txt
1565    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1566    o Added useSingleCpuIO option (see PARAMS.h).
1567    o Updated useSingleCpuIO option in mdsio_writefield.F to
1568      work with multi-field files, e.g., for single-file pickup.
1569    o pkg/seaice:
1570      - bug fix in growth.F: QNET for no shortwave case
1571      - added HeffFile for specifying initial sea-ice thickness
1572      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1573    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1574      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1575    o pkg/seaice:
1576      - adjoint-friendly modifications
1577      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1578    
1579    checkpoint48e_post
1580    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1581    o dynamics: change definition of computational domain & adapt mom_fluxform
1582      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1583    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1584        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1585        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1586        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1587        inverted_barometer solid-body.cs-32x32x1
1588      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1589    
1590    checkpoint48d_post
1591    o in preparation for r*:
1592     a) use pre-computed gradient of hydrostatic potential:
1593        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1594     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1595        => affects results of glob_oce_pressure (different truncation error)  
1596      update output.txt of ideal_2D_oce & global_ocean_pressure
1597    
1598    checkpoint48d_pre
1599    o in preparation for r*:
1600      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1601      pass the 2 comp. of the grad. as arguments to momentum S/R.
1602      but for the moment, only used if it does not change the results.
1603    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1604    
1605    checkpoint48c_post
1606    Modifications in treatment of initial flux forcing controls
1607    to avoid extra storing of flux fields.
1608    
1609    checkpoint48c_pre
1610    o Added tidal_basin_2d experiment (currently 1D!)
1611    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1612    
1613    checkpoint48b_post
1614    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1615     (modification to pressure gradient not yet implemented)
1616    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1617      (for U & V) that are used for vertical advection of momentum.
1618    
1619    checkpoint48a_post
1620    o In preparation for r*, use temp. array to compute vertical transport
1621       in flux-form momentum pkg. => change results of few test-exp.
1622      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1623                        lab_sea, natl_box & plume_on_slope
1624    
1625    checkpoint48
1626    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1627    
1628    checkpoint47j_post
1629    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1630    o moved adexch from forward_step to addummy_in_stepping
1631    o added exch in ctrl_map_...
1632    o aveFreq.=0. at end of cost_final to avoid overwrite in
1633      reverse checkpointing loop
1634    o Yet more changes in gmredi:
1635      * adgmredi_calc_tensor
1636        avoiding all recomputation of gmredi_slope_limit
1637      * adgmredi_x/y/rtransport
1638        added flag for excessive storing to avoid recomp. of
1639        u/v/rtans, dTdx/y/z
1640        -> this is not really necessary and very memory-consuming
1641      * adgmredi_slope_psi:
1642        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1643      * gmredi_slope_limit
1644        re-activated full calculation of taperfct for case 'ac02'
1645    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1646    
1647    checkpoint47i_post
1648    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1649    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1650      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1651    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1652    o gmredi: fix few bugs.
1653    
1654    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1655    This will be a good checkpoint to plug into the ecco-branch.
1656    o few modif.'s to get latest version adjointed
1657      (mainly kick out code in ini_linear_phisurf)
1658    o modif's to run adjoint with exactConserv
1659    o case GM_BOLUS_ADVEC should be cleaned
1660      S/R gmredi_slope_psi should be cleaned
1661    o verification/carbon now has exactConserv=.TRUE.
1662    
1663    checkpoint47g_post
1664    o time-average AIM output: becomes independent from statvars time-average
1665      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1666    o After TAF bug fix:
1667      Tested adjoint of gmredi package.
1668      Tests were done with checkpoint47 rather than with latest
1669      checkpoint47f_post since the latter is broken for the adjoint
1670      verification/carbon/ contains both ADM and TLM gradient checks.
1671    Here they are, before they get changed/lost/stolen.
1672    Mostly modif.'s to fix numerical sensitivities.
1673    Gradient checks OK for
1674    - GM_taper_scheme:
1675      * clipping
1676      * ac02
1677      * linear
1678      * glw91
1679      * dm95
1680      * ldd97
1681    - GMREDI_OPTIONS:
1682      * GM_VISBECK_VARIABLE_K
1683      * GM_NON_UNITY_DIAGONAL
1684      * GM_EXTRA_DIAGONAL
1685      * GM_BOLUS_ADVEC
1686    in conjunction with data.gmredi parameters to be checked in
1687    in a few minutes under verification/carbon/code/
1688    
1689    checkpoint47f_post

1696      - usage examples are Experiments 8 and 9 in
1697        verification/lab_sea/README
1698      - verification/lab_sea default experiment now uses
1699        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1700    
1701    checkpoint47e_post
1702    o created a tag prior to creating a branch
1703    
1704    checkpoint47d_post
1705    o fixed bug in the oceanic pressure coordinates code: vertical viscosity

1716      -  uses pkg/therm_seaice and pkg/bulk_forcing
1717    
1718    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1719    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1720      when using P-coordinate; only implemented for atmospheric config.
1721    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1722      NOTES: requires option NONLIN_FRSURF to be "#define".
1723    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1724
