3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o mnc-ifying the seaice package
7    o introduced an alternative length scale calculation for use in the limiting
8      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
9    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
10    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
11      as well as grad(vort3).  Made it compatible with both approximate form
12      for the cubed sphere and full form of these gradients.  Added flag
13      useFullLeith to select between approximate and full form.  
14    o add "d0" in getcon.F to reduce differences between compilers/platforms
15      update output.txt of exp. fizhi-gridalt-hs
16    o change port_rand funtion to allow to set the seed.
17    o fix obscure MNC bug involving conversion between reals and integers
18      - it caused no problems with certain (eg. gcc, ifc) compilers but the
19        new version is now more standards-compliant
20    o adjoint-related modifications
21      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
22      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
23      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
24    
25    checkpoint57e_post
26    o Adding eddy stress controls a la Ferreira et al.
27    checkpoint57e_pre
28    
29    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
30      update output.txt of exp. fizhi-gridalt-hs
31    o add more "Z" dimensions and associated coordinate vars to MNC
32    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
33    o parameter calendarDumps: when set, approximate months (30-31 days) and years
34      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
35      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
36      months and years.  Requires pkg/cal.
37    o diagnostics: add pickup functionality
38      - off by default for backwards compatibility
39      - current version only uses MDSIO -- MNC will be added
40    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
41    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
42    
43    checkpoint57d_post
44    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
45    o modify verification/ideal_2D_oce so that it tests the creation of mnc
46      output from the diagnostics package
47    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
48    o make genmake2 more portable by using ".$FS" instead of ".f" for more
49      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
50    o add coordinate variables to the MNC output from the diagnostics package
51    o change MNC-flags default value: true when useMNC=TRUE
52    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
53      the ability (off by default) to read the grid information using MNC
54    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
55    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
56    o do snap-shot diagnostics at the middle of the time-interval (instead of
57      at the end).
58    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
59      new test for AIM with thSIce + slab-ocean
60    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
61    o move state variable diagnostics to the beginning of the time step ;
62      (note: still needs some work specially for snap-shot diagnostics)
63      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
64    
65    checkpoint57c_post
66    o Change testing option (-ieee) to get closer agreement between g77 & ifort
67    o generate new output.txt files on faulks with g77 & the new -ieee option
68    checkpoint57c_pre
69    
70    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
71      update output.txt of exp. global_ocean.90x40x15
72    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
73      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
74    o add saltFlux(+File) forcing capability with periodicExternalForcing
75    o allow to use pkg diagnostics for GM-Redi & ThSIce output
76    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
77    o improvements for the MNC output from DIAGNOSTICS:
78      - correct handling of the unlimitied dimension
79      - all dims now have associated coordinate variables
80      - variables located at U, V, and Corner ("Z") points are now written
81        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
82        *all* data points are output
83    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
84    o added pkg/seaice/seaice_monitor.F
85    o mdsio_readfield.F can now read files visible only to master MPI process.
86    o pkg/seaice: some test code for ice-modified ocean stress
87    o exf_getffields interpolation defaults to bilinear for all scalar forcing
88      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
89      spurious negative numbers for precipitation and humidity.  Will cause
90      some small numerical differences for integrations using pkg/exf/exf_interp.F.
91    o pkg/ctrl/
92      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
93        May be enabled via doPackDiag
94      *  introduce z-scaling of
95         + gradient (doZscalePack) and
96         + control (doZscaleUnpack)
97    o pkg/mdsio/
98      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
99      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
100    
101    checkpoint57b_post
102    o simplify options in diagnostics_fill arguments (remove weird combinations)
103    o fix MNC coordinate variables so that they now contain per-face index
104      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
105      general, EXCH2 grids are only aligned to a "local" coordinate system
106    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
107    o Implement instantaneous output within pkg diagnostics:
108      setting a negative frequency in data.diagnostics produces
109     "snap-shot" output (as opposed to time-average if freq > 0)
110    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
111      NOTE: change ptracer diagnostics name: use 2 characters to work with
112            more than 9 tracers. Add also diagnostics of advect & diffus flux.
113    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
114      becomes the coordinate variable for the 'T' dimension
115    o add CF-style coordinate variables to MNC
116      - just a first cut:  numbers are meaningless on the cubesphere and
117        missing along the T axis but otherwise it works!
118    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
119    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
120    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
121      this is based directly on what the model compute, so that the content of
122      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
123    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
124    o clean up build options files for SunOS, in particular
125      - remove -traditional from xmakedepend
126      - change -xarch=v9 to -xarch=native for f77
127      - restore use of make (not gmake)
128      - add CC=gcc if using g77
129    o changes per discussion of AM, JMC, & EH3 today:
130      - move redundant "grid" variables out of "state" -- in preparation of
131        creating proper CF-style coordinate variables and in recognition
132        that any/all grid variables can be easily copied (eg. w/NCO) from
133        the grid files into any of the other NetCDF files
134      - *always* output grid variables with MDSIO (this will eventually be
135        changed)
136      - output MNC grid file if useMNC is true
137    o every instance of _END_MASTER() has been found and replaced with
138      _END_MASTER( myThid ) in order to satisfy certain picky Sun
139      preprocessors
140    o re-arrange diagnostics pkg initialisation:
141     - allow each package to extend the available diagnostics list
142     - add some checking and fix small problems (multi-threaded, ...)
143     - new S/R diagnostics_fill (replace fill_diagnostics):
144       look through the short list of active diag. (instead of the long list)
145       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
146    
147    checkpoint57a_post
148    o this set of changes restores TAMC compatibility
149      tested for global_ocean.90x40x15 adjoint on trough
150      (what a pain)
151    
152    checkpoint57a_pre
153    o some modifs in tools/build_options for sunos
154    o call ctrl_pack for ctrl at end for optimcycle=0
155    
156    checkpoint57
157    o add horizontal bi-harmonic viscosity for vertical velocity
158      - new parameter viscA4W (defaults to viscA4)
159      - affects only non-hydrostatic code
160      - to be done: no-slip lateral boundary conditions
161    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
162    o implement Implicit Vertical advection for pTracers
163    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
164      (implemented also for implicit vertical diffusion & advection)
165    o OBCS: extend application of tracer open boundary conditions
166      to a strip beyond the boundary of width Olx/Oly
167    o add call monitor to TAF set of required calls (flow directives)
168      and include in natl_box_adjoint
169    o untangle a few ifdefs related to cost, ctrl, autodiff
170      untangel a few ALLOW_ECCO_OPTIMIZATION
171    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
172      (theta2, salt2 in ecco_cost_weights)
173    
174    checkpoint56c_post
175    o OBCS as control variables
176      - update ctrl_ad_diff.list, obcs_ad_diff.list
177      - remove balance of obcs controls from default
178      - fix index bug nobcs in ctrl_init
179      - fix dummy fields filen in ctrl_pack
180      - add dummy weights for obcs
181    o lsopt: comment out fort.94 output
182    o optim:
183      - remove unnecessary header files
184      - adjusted namelists
185      - add xerbla.F to Makefile
186    o exf:
187      - multiple modifications of exf_check_range
188      - unit change in exf_init_runoff from [m/year] to [m/s]
189    o mdsio:
190      - i/o-vector change debugLevel from debLevA to debLevB
191    
192    checkpoint56b_post
193    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
194      is called from DO_THE_MODEL_IO
195      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
196      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
197      - clean up PTRACERS_WRITE_TIMEAVE a little
198    o add another verification experiment that tests both the cfc-pkg and
199      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
200      reactive tendencies treated inline with regular timestepping
201    o testreport previously did a lousy job of comparing small numbers, so
202      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
203      implemented in the little c-progam tmp_cmpnum.c which is embedded in
204      testreport.
205    o ptracers_monitor: bug fix for MPI
206    
207    checkpoint56a_post
208    o GCHEM: finish reorganizating the package
209      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
210        (introduces another 3D-array for each passive tracer, but only if
211        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
212        gchemTendency is not needed because the timestep is done separately)
213      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
214      - GCHEM is now---more or less cleanly---separate from PTRACERS
215      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
216        so clear to me how that should be done in a general way.
217    o CFC: improve formatting of output in CFC_ATMOS
218    o PTRACERS:
219      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
220        that ALL experiments with ptracers enable can be checked. This makes
221        GCHEM_MONITOR obsolete.
222      - include a runtime parameter PTRACERS_monitorFreq that defaults to
223        monitorFreq
224      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
225    o add PTRACERS (PTR0[1-5]) to testreport output
226    o exf_check_range:
227      * default changed to .TRUE.
228      * will check values for niter0 if debLevA, every timestep if debLevB
229      * STOP in exf_check_range if 'out of range'
230      * range chosen generous to allow for potential extema
231      TBD: a version with stricter range
232           permitted range would be runtime parameters
233    o GMredi:
234      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
235      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
236      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
237    o GCHEM:
238      - move call to GCHEM_FORCING_SEP, so that it is now called before
239        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
240      - introduced a useGCHEM runtime flag and applied it everywhere.
241      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
242        this flag is now only visible within GCHEM-pkg routines.
243      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
244        be replaced by a 3D array that is computed before thermodynamics; for
245        this, the tracer ID iTracer had to be included into the parameter list
246        of ptracers_forcing
247      - set up forward_step to call gchem_forcing, that will replace
248        gchem_forcing_int in ptracers_forcing
249      - cleaning up
250    o small cleaning of exch2: remove files that are also in eesupp/src
251    
252    checkpoint56
253    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
254    o mnc: cleanup "full" files--fixes out-of-memory problem
255    o ECCO-GODAE
256      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
257      * fully merged and updated from SIO code
258        windstress sign change affects
259        - exf_inscal_[u/v]stress
260        - sign of xx_tau[u/v] adjustments
261        - signs in cost_scat
262      * ctrl_get_gen: avoid update of tau[u/v] for first few days
263      * natl_box_adjoint updated and compressed
264      * 2-level checkpoint switch added
265        (tested in EXP. 1 of natl_box_adjoint)
266      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
267    o SVD
268      * first complete, non-hacked version for SVD calculations
269      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
270        performed via direct access files admtlm_vector.it????
271        (via ctrl_[un]pack)
272      * optimcycle is used for ARPACK iteration counter
273        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
274      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
275        and add linear transforms where necessary
276      * controls are initial/final SST, SSS (can be extended; need to check
277        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
278    o mdsio: filename info to both stderr, stdout
279    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
280      from sign change
281    
282    checkpoint55j_post
283    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
284      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
285    o add consistent build directories and .cvsignore files to verification
286    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
287    o make all subroutines 30 or less characters in length for certain older
288      compilers to work (a thorough search only turns up two routines in
289      pkg/ptracers)
290    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
291      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
292    
293    checkpoint55i_post
294    o change arrays for total vertical diffusivity (2.D if explicit,
295      3.D if implicit) ; each ptracer uses its own background value.
296    o added mnc/NetCDF output capability to ocn_compon_interf
297      - added bits to verification/cpl_aim+ocn so that it can run on
298        ITRDA and other clusters without the mpirun "-wd" option
299    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
300      configuration
301    o give MNC the ability to create additional files rather than
302      exceeding a specified file size limit "MNC_MAX_FILESIZE"
303      - the default is just less than 2GB which is a practical limit
304        on many systems
305    o Compute the non-local term using either KPP vertical diffusivity (=default)
306       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
307    
308    checkpoint55h_post
309    o add verification test "vermix"
310    o remove all the *_ioinc flags and replace with the single global
311      outputTypesInclusive flag
312    o allow to set a vertical profile of vertical diffusivity for T & S
313    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
314    o useMNC moved from data.mnc to data.pkg
315    
316    checkpoint55g_post
317    o Renaming carbon AD experiments to comply with testreport conventions
318    o Updating adjoint of Held-Suarez hs94.1x64x5
319    o Fixing directives for non-ECCO forward_step, after ECCO directives
320      have been fixed to avoid recomp. of do_oceanic_phys
321      Works well for global_ocean.90x40x15,
322      but recomp. issue remains for carbon
323    o Updating adjoint output for natl_box_adjoint after
324      pkg/ecco has been modified (see taga c55d_post)
325    
326    checkpoint55f_post
327    o rename to timeave_init_fixed
328    
329    checkpoint55e_post
330    o some delicate re-shuffle of store directives to avoid one
331      extra call of do_oceanic_physics
332      affects ecco_the_main_loop.F, do_oceanic_physics.F
333      checkpoint_lev1_directives.h
334    o NB: this may break global_ocean adjoint temporarily,
335      but it is clear how to fix it. Will do later, need this now.
336    
337    checkpoint55d_post
338    o ECCO specific cost function terms (up-to-date with 1x1 runs)
339    o ecco_cost_weights is modified to 1x1 runs
340    o modifs to allow observations to be read in as
341      single file or yearly files
342    o enable to read exf forcing fields as either
343      single file or yearly files (flag useExfYearlyFields)
344    checkpoint55d_pre
345    
346    o switch between 2-level and 3-level checkpointing
347    o add ability of MNC to write local and "partial" (eg. 2D slices where
348      the full 3D field is never actually stored) arrays to NetCDF files
349      with the correct (that is, the complete multi-dimensional) set of
350      array indicies
351      - used in mom_vecinv() to write the diagFreq output
352      - tested (demonstrated) in verification/aim.5l_cs
353    o further mnc-ification
354      - add verification/lab_sea to the list with mnc setups
355      - fix undefined mnc v-names in cd_code
356      - add kpp to mnc output (both snapshot and timeave)
357    o non-hydrostatic code
358      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
359        in calc_gw.F
360      - defaults to viscAh
361      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
362        friction or Leith) in non-hydrostatic mode, as long as there is
363        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
364    o pkg/cost
365      extend simple cost functions to treat time mean quantities
366      (T,U,V) via cost_accumulate_state from cost_tile
367    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
368        be 2 times larger than the minimum size the advection scheme requires.
369        now get a perfect conservation of salt in advect_cs test-exp (updated)
370    o GGL90 (Gaspar's TKE mixed layer)
371      - add horizontal diffusion of TKE, requires exchanges in
372        do_fields_blocking_exchanges, horizontal diffusivity is zero by
373        default. In OPA there is no horizontal diffusion of TKE but the
374        mixing coefficients are computed from a horizontal average of TKE of
375        6 points or so. I think that diffusion has a little more physical
376        justification.
377      - clean up ggl90_calc in the hope of reducing memory usage (this hope
378        was in vain)
379      - mask tke-variable in ggl90_init
380    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
381    o fix biharmonic diffusion on CS-grid.
382    o more obcs stuff
383      - added obcs_external_fields_load as an alternative to the EXF-pkg option
384        for reading boundary values. This routine is called from
385        obcs_prescribe_read
386      - updated obcs_check
387      - changed sponge layer relaxation parameter units for days to seconds
388      - turned off sponge layer by default
389      - changed argument list of OBCS_CALC to myTime+deltaTclock
390      - fixed about 35 bugs in obcs_external_fields_load
391    
392    checkpoint55c_post
393    o obcs stuff
394      - new runtime flags useOBCSprescribe, useOBCSbalance
395      - re-arranged obcs_calc
396      - moved exf_getobcs to obcs_prescibe_read
397        obcs_prescibe_read is called after ORLANSKI stuff
398        and independent of it (executable can contain all).
399      - updated obcs_check
400      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
401        These may be necessary only if tangential velocities are
402        prescribed at OB, not sure, needs testing.
403    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
404      which simplifies the calls and passes the ifc check-bounds test
405    
406    checkpoint55b_post
407    o add a 2D scalar, Z location, exchange_2 routine.
408    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
409      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
410      affects advect_cs results (for the wrong reason): update output.txt
411    o use a more standard discretization for biharmonic viscosity ;
412     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
413      affects results of dome set-up: update output.txt
414    o fix gad_advection.F (CubedSphere part), back to version 1.23
415    o fix bug in mom_vi_del2uv.F (CubedSphere part).
416    
417    checkpoint55a_post
418    o merged code to
419      * prescribe/read time-dependent open boundaries
420        (works in conjunction with exf, cal)
421      * sponge layer code for open boundaries
422      * each boundary N/S/E/W now has its own CPP option
423        (healthy for the adjoint)
424    
425    checkpoint55
426    o up-to-date adjoint of previous breaks
427      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
428      - global_ocean_ebm: adjoint still needs fix (TLM ok)
429      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
430      - carbon: * remove tr1-related adjoint verification
431                * add ptracer as control variable
432    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
433      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
434    
435    checkpoint54f_post
436    o in verification/carbin/ remove experiment related to
437      ALLOW_PASSIVE_TRACER (array tr1 etc)
438      code_ad/ input_ad/ results_ad
439    
440    o add two new packages
441      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
442        + subject to optimization (memory)
443      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
444        + subject to reordering (many GOTOs in the original code)
445        + so far opps is called for every (i,j) point, and then operates in
446          the vertical; one may want to reorder the scheme in order operate in
447          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
448          fields)
449    o overhaul of IO so that we now have flags for MDSIO and/or MNC
450      - all verification tests compile and run with linux_ia32_g77
451      - defaults are compatible with current input files--nothing
452        should change if you were not previously using MNC
453      - MNC output has been added in numerous places (eg. timeave)
454        but there are still a few writes not yet do-able with MNC
455        (this is in progress)
456      - flags now allow for either/or/both use of MDSIO and MNC and
457        documentation will soon follow
458      - numerous small formatting cleanups for ProTeX
459    o add version info (via BUILD_INFO.h) to MNC and stdout
460    
461    checkpoint54e_post
462    o add two new packages
463      - pp81 (Packanowski and Philander, 1981), Richardson number and
464        stratification dependent mixing
465      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
466      - these scheme operate in a similar manner as KPP (without ghat, of
467        course), however there is only one diffusivity that is used for both
468        temperature and salinity (and passive tracers)ç
469    o add offline package
470    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
471      provided by Stephanie Dutkiewicz
472    o genmake2: add ability to search for C compilers and cleanup test output
473      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
474    
475    checkpoint54d_post
476    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
477    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
478      leading to additional shift by 5 days each year of integration
479       (i.e. leading to considerable offset over the years)
480    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
481    o start with no AB and no initial filtering (staggerTimeStep):
482      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
483    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
484      (external loading & cpl import/export stay in forward_step.F)
485    o update coupling interface to work with new staggerTimeStep
486    o change MDSIO ptracers_pickup.
487    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
488    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
489    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
490    
491    checkpoint54c_post
492    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
493      this affects (truncation error) output.txt of test-exp:
494       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
495    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
496    o change Qnet to always be the net heat flux, (+upward).
497      affects (truncation error) output of natl_box exp.: updated
498    o define the max number of passive tracers in PTRACERS_SIZE.h
499    o start to test mnc routinely in exp0
500    o add sea-ice loading (sIceLoad) as a new forcing field.
501    
502    checkpoint54b_post
503    o add testreport "-j JOBS" option for parallel builds (tested and pretty
504       impressive on Altix and Opteron systems)
505    o diagnostics can now write NetCDF files through the mnc package
506    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
507    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
508    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
509      affects (truncation error) output of lab_sea & natl_box exp.: updated
510    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
511    
512    checkpoint54a_post
513    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
514    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
515    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
516    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
517      + internal_wave (shift in writing cg2d_ini_res)
518    checkpoint54a_pre
519    
520    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
521      - modified verification/lab_sea and natl_box_adjoint accordingly
522    
523    checkpoint54
524    checkpoint53g_post
525    o prepare splitting of thermodynamics: store convect.counter in common block
526    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
527      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
528    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
529    o new parameter "nShapS": allow to treat differently S from T (nShapT)
530    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
531    o restore adjointability
532    
533    checkpoint53f_post
534    o modifications that affect AIM experiment results (update output.txt):
535      - no advection of S at top interface Nr (pkg/generic_advdiff)
536      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
537    o AIM pkg:
538      - include stability function into surf.Flux derivative relative to Tsurf
539      - calculate clear-sky radiation & surface temp. change (for diagnostics)
540    
541    checkpoint53e_post
542    o merged cylindrical coord configuration
543    o added rotating_tank experiment
544    checkpoint53e_pre
545    
546    checkpoint53d_post
547    o faulks upgraded: re-generate output.txt that have changed:
548       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
549    o Added Bryan and Lewis, 1979, vertical diffusivity profile
550    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
551    o added Sadourny discretization of Coriolis
552      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
553      - re-enabled use of omega3 (useAbsVorticity)
554    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
555      vector-invariant equations
556      - note: does *NOT* yet use same variable visc. for no-slip BC's.
557    o recoded the lateral boundary conditions for non-hydrostatic w, this time
558      hopefully without new bugs
559      - still to do: biharmonic friction for non-hydrostatic w
560    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
561    o regenerated output for global_ocean_ebm (using -ieee)
562    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
563      of mom_common/
564      - simple re-arrangement of instructions within computing loop
565    checkpoint53d_pre
566    
567    checkpoint53c_post
568    o new version of coupler for AIM+thSIce and Ocean models
569     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
570     - land: change Evaporation of snow
571     - aim with thSIce: fix bug in snow-precip.
572    o changes to calc_gw.F
573     - bug fix for w^2 term near the bottom boundary
574     - (hopefully) improve the lateral slip boundary condtions for use with
575        partial/looped cells
576      - because the bug fix changes two verification experiments anyway (exp5
577        and plume on slope), change the lateral boundary condition from half slip
578        to the value of no_slip_sides
579    o ebm package wasnt quite up to the parallel task. Fixed that.
580    o Adjoint of EBM package + verification
581      * TLM OK
582      * ADM not sufficient accuracy yet (needs further testing)
583    
584    checkpoint53b_post
585    o Commiting new energy balance model to repository
586      * package is pkg/ebm
587      * verif. is verification/global_ocean_ebm
588      * references are in ebm_driver.F
589    C      * X. Wang, P. Stone and J. Marotzke, 1999:
590    C        Global thermohaline circulation. Part I:
591    C        Sensitivity to atmospheric moisture transport.
592    C        J. Climate 12(1), 71-82
593    C      * X. Wang, P. Stone and J. Marotzke, 1999:
594    C        Global thermohaline circulation. Part II:
595    C        Sensitivity with interactive transport.
596    C        J. Climate 12(1), 83-91
597    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
598    C        Destabilization of the thermohaline circulation
599    C        by atmospheric eddy transports.
600    C        J. Climate 7(12), 1870-1882
601    o Will need long integration testing.
602    checkpoint53b_pre
603    
604    o created pkg/mom_common in preparation for variable viscosity code
605    o renamed and split ini_mnc_io
606    o pkg/land: only liquid water can diffuse or run-off
607    o AIM using land: soil wetness availability account for snow
608    o added printMapIncludesZeros to EEPARMS namelist
609    
610    checkpoint53a_post
611    o restore TAMC compatiility for exf_constants.h
612      (no usage of _d in .h)
613    o Additional storing in KPP in an attempt to fix
614      TAMC problem with adjoint of KPP code.
615      (no success...)
616      Identical code works fine with TAF.
617    o Fixed verification/natl_box_adjoint experiments.
618      Initial conditions for Experiments 4 and 5 are now
619      set to "SEAICE_initialHEFF=0", which is more reasonable,
620      and hence gives results closer to that of Experiment 2.
621      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
622    
623    checkpoint53
624    o stable checkpoint with up to date adjoint
625      TLM tests only run for 1st grdchk at the moment. Its unclear if
626      this is a code problem or a problem with resetting code for g_
627      variables that is being autogenerated wrong.
628      Otherwise:
629       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
630       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
631         are both still in chaos following their security messes.
632    
633    checkpoint52n_post
634    o various build (mostly genmake2) changes including:
635      - ability to build/run more easily within Cygwin and MacOS X
636      - more complicated Makefiles with a stronger dependence on Gnu Make
637    o pkg/seaice modifications
638      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
639        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
640        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
641      - changed proxy for geostrophic velocity and updated
642        verification/lab_sea/results/* accordingly
643      - removed ADI dynamic solver from pkg/seaice
644      - replaced all occurrences of 1/CSTICE or 1/CSUICE
645        they caused a segmentation fault under certain circumstances
646      - removed unused field WATR
647    o bug fix in exf-package:
648      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
649         now reflect that.
650    o small fixes in the cal-package:
651      - set reference date to first of January for the 'model'-calendar
652      - failing of cal_CheckDate in cal_FullDate now actually results in a
653        warning
654    o small modifications in exf-package to increase flexibility:
655      - change climtempfreeze from a constant to a runtime parameter that
656        is specified in data.exf_clim (default = -1.9)
657      - introduce runtime parameter windstressmax (default = 2.0) that is
658        specified in data.exf
659    o fix in pkg/thsice:
660      - update Evap (Tsf changes) to be consistent with Latent heat flux
661      - maintain snow precipitation unchanged (even if Tsf >=0).
662     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
663    
664    checkpoint52m_post
665    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
666      this does not change any of the results, because myIter=0 in swfrac always
667      lead to jwtype=2 (the default anyway), but the call makes little sense
668      as a default
669    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
670    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
671      atmospheric model (AIM) to use it ; add a "slab ocean" component.
672    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
673    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
674    o extending useSingleCpuIO option to work with new exch2 I/O format
675      - old-style, missing-tile I/O is still accessible by defining CPP
676        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
677    o monitor package can write to NetCDF files and/or STDOUT
678    o fix re-definition bug in MNC_GRID_INIT_ALL()
679    o doc/api_reference added
680      - a framework for building an API Reference Manual using all
681        the "protex" comments embedded in the code
682      - see pkg/generic_advdiff, pkg/mnc for examples
683    o MNC:
684      - make myThid the last argument for all subroutines
685      - new default for the grid files: NO halos
686      - add useMNC and other run-time flags
687      - separate per-file-group handling of the unlimited dimension
688      - early initialization of MNC w/ flags read at the eeboot stage
689        and lookup tables set in initialize_fixed
690      - write all MNC output to a freshly-created directory
691    o thermodynamics sea-ice (thsice) is now tested with testreport.
692    o test exp. advect_cs: use the standard cs32 grid ; update output.
693    o Added functionality to grdchk:
694      pick global i,j,k position (or nearest wet) where to perform check.
695    
696    checkpoint52l_post
697    o new land formulation:
698      a) use ground enthalpy as prognostic variable to ensure exact
699         energy conservation.
700      b) account for water temperature and for latent heat of freezing
701         in all processes (rain, run-off, ground storage)
702      c) compute surface and ground temperature implicitly.
703    o aim_v23 modification for new land model:
704      a) Treat separately land / ocean / sea-ice surface fluxes
705         to allow implicit computation of land & sea-ice surface temp.
706      b) add snow precipitation.
707    checkpoint52l_pre
708    
709    o fix problem (when 1 tile is empty) in min/max monitor.
710    o fix bug in timeAve (u,vZetatave in common block)
711    o no restoring terms under ice for pkg/seaice
712    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
713    o bug fix for pkg/seaice pickups
714    o change MNC call locations and add coordinate attributes
715    o mask vorticity at the corner ; affects global_ocean.cs output
716    o fix ini_curvilinear_grid ; test CS experiments with mpi
717    o aim.5l_cs: modify sea-ice fraction input file ; update output
718    o exf: Adding simple range check routine for exf fields after read
719    
720    checkpoint52k_post
721    o removed top-level directory "diags"
722      - we migrated these functions to pkg/timeave a long time ago
723    o fixed bug introduced in pkg/monitor
724    o accuracy ctrlprec = 32 insuffient for gradient checks using
725      averaged fields (I/O via cost_averages)
726      -> use ctrl.h in active_file*.F to control I/O precision.
727    o paramter list of CALL ADTHE_MAIN_LOOP
728    o added initial do_the_model_io to ecco
729    o set all ...Freq to zero after cost_final
730      taveFreq, dumpFreq, pChkptFreq
731    o MAIN and ECCO differentiability restored
732    
733    checkpoint52j_post
734    o fix nchklev in tamc.h for global_ocean...
735    o Bringing flow and store directives up-to-date
736    o Really weird thing!
737      call do_the_model_io from the_main_loop with parameters
738      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
739      TAF places a faulty re-call of initialise_varia
740      after cost_final call which should not be there!
741    checkpoint52j_pre
742    
743    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
744      error messages
745    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
746    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
747      debug output
748    o modfied mdsio_writefield.F to handle non-global files under exch2
749    o update AIM Cubed-Sphere exp (aim.5l_cs):
750      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
751    o update AIM Equatorial Channel exp:
752      use standard aim_v23 pkg and change the SST fields to be more realistic.
753    o globalFile now works with exch2
754    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
755      mon_vort3.F to make exch2 friendly with >1 tile per cube face
756    o limit timeave output for hi-res integrations
757    
758    checkpoint52i_post
759    o removed CPP_EEOPTIONS.h from verification/*/code
760    o updated the tiling for global_ocean_pressure
761    checkpoint52i_pre
762    
763    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
764      the old pkg/aim).
765    
766    checkpoint52h_pre
767    o shortened offending lines in exch2_send_rx?.template
768    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
769    o genmake2: add build & execute test for NetCDF code
770    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
771      old grid files, moved CPP_EEMACROS.h to pkg/exch2
772    o added useSingleCPUIO flag to monitor.F and mon_out.F
773    o added temporary hack for sea-ice dynamics on the cube:
774      metric terms are ignored and it is assumed that
775      there is no sea-ice on cube faces 1, 2, 4, and 5.
776    
777    checkpoint52f_post
778    o added exch2 cube routines to pkg/exch2

785      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
786    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
787      to work with implicit vertical advection and AB ;
788    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
789    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
790     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
791    checkpoint52e_pre
792    
793    o fix bug in impldiff when Nr=1 or Nr=2.
794    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
795    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
796    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2

803    o re-tiled many expts to allow comparison in multi-processor mode
804      - updated output accordingly
805      - changed hs94.128x64x5 to use intial T from file rather than use the
806        random number generator
807    o add infrastructure in model routines for fizhi and gridalt packages
808    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
809    o changes to permit hi-res, cubed-sphere, configuration
810      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
811      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
812      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
813        of surface winds for the cube
814      (A verification experiment, based on global_ocean.cs32x15, but with
815       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
816       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
817       complete with example surface forcing files and matlab scripts to look
818       at the output and compare it with that of global_ocean.cs32x15.)
819    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
820       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
821       to conform to the common rule.
822    o check-in the first version of the coupler + interfaces for multi-components
823       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
824       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
825       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
826       - ocean and atmos. share the same horizontal grid (no interpolation).
827       - exchanges between component and coupler is done in forward_step
828    o new verification experiment, cpl_aim+ocn:
829       coupled ocean - AIM atmosphere on cs32 grid.
830    
831    checkpoint52d_pre
832    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
833    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
834    
835    checkpoint52c_post
836    o Fixing OPTIONS files for use of exf:
837      - ALLOW_ECCO not needed
838      - ECCO_CPPOPTIONS.h should not be included from
839        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
840        as has been the case in the past
841      - All cal/exf related options are currently set in
842        single header file. Should remain so until we
843        agree on a consistent new policy.
844    o Removed all CPP options for cal package.
845      cal has no more CPP options.
846    o modified STOREs in GAD_ADVECTION
847    o corrected key comp. for passkey
848    
849    checkpoint52b_post
850    o new version: "thsice" of thermodynamic sea-ice pkg:
851     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
852     - modify fluxes but do not change theta directly;
853     - light cleaning of bulk_force pkg (still needed with thsice).
854     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
855       + output_thsice.txt to test thsice & bulk_force pkgs.
856    o put back grid & coriolis monitor output.
857    checkpoint52b_pre
858    
859    o call "do_the_model_io" at the beginning (=> dump initial state)
860    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
861    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
862      (need info on NUMBER_OF_PTRACERS)
863    o missing PTRACERS headers in some routines
864    o default tamc.h in pkg/autodiff supposed to crash
865      to ensure proper customization
866    
867    checkpoint52a_post
868    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
869      - moved surfaceTendencyTice from pkg/seaice to main code
870      - subroutine FREEZE_SURFACE now limits only surface temperature
871        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
872        => new output.txt for global_ocean.cs32x15 & global_with_exf
873      - keep the old version of FREEZE for backward compatibility;
874        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

883    o some bug fixes for #undef REAL4_IS_SLOW
884    
885    checkpoint52 = ecco_c52_e35
886    o after testing adjoints of checkpoint51u_post
887    
888    checkpoint51u_post
889    o this is the post-merge tag of the ecco-branch
890      (needs another clean checkout and re-testing)
891    o various natl_box_adjoint configs and results
892      but no input fields
893    o obcs adjoint not yet merged!
894    o adding ECCO global 1x1 and 2x2 degree configs
895    o updated/extended some store directives for seaice
896    o pkg/ecco now containes ecco-specific part of cost function
897    o top level routines the_main_loop, forward_step
898      supersede those in model/src/
899      previous input data.cost now in data.ecco
900      (new namelist ecco_cost_nml)
901    o in ctrl/ cleaned some cross-dependencies and updated CPP options
902    
903    checkpoint51t_post
904    o this is the pre-merge tag of the ecco-branch
905    
906    checkpoint51s_post
907    o cleanup: removed various obsolete #define-s
908    o pkg/grdchk
909      - renamed 'ph-grd 3' to 'grad-res'
910      - merged from ecco-branch
911        (remaining bug fixes for obcs gradient checks)
912      - additional high-precision output for testreport
913        (grep for 'precision_grdchk_result')
914    
915    checkpoint51r_post
916    o cleaned up or removed CPP_OPTIONS.h files
917    o updated results for some of the tests to reflect the new
918      optfiles (-ieee: -O0 instead of -O3)
919    
920    checkpoint51q_post
921    o cd_code:
922      - moved cd_scheme.F -> cd_code_scheme.F
923      - separate read_checkpoint from cd_code_ini_vars.F
924      - separated cd_code part from write_checkpoint
925      - updated AD_SOURCE, generated .flow

933      - confined inclusion of AD_CONFIG.h to where necessary.
934    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
935    
936    checkpoint51p_post
937    o create initial cd_code package
938      - WARNING: the initialization of fields within packages
939        is broken because INI_FIELDS (where READ_CHECKPOINT is
940        called) is called *before* PACKAGES_INIT_VARIABLES.
941        This seems to be backwards since
942        1) its important to initially zero the entire field including
943           the "halo" region
944        2) zeroing needs to be done *before* reading pickup info
945           and the pickup call might or might not happen in any
946           particular run
947      - this needs an overhaul for R2
948    o cleanup verification/*/code/GMREDI_OPTIONS.h
949    o cleanup testreport
950

986         global_ocean.cs32x15, and global_with_exf)
987    o added surface flux output variables to TIMEAVE_STATVARS
988    
989    checkpoint51n_pre
990    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

1178    checkpoint50f_pre
1179     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
1180          + change Evap over land. (update aim.5l_cs output)
1181     o added missing .cvsignores and made uniform across expts
1182     o changed configuration of tidal_basin_2d expt
1183     o added pkg/debug functions for tracing code in fatal crashes
1184     o tidied pkg/monitor to use MONITOR_OPTIONS.h
1185     o new fn in pkg/monitor to stop model if solution grows too big
1186     o removed lots of single quotes from comments
1187    
1188    checkpoint50e_post
1189    o make KPP work with PTRACERS
1190     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1191       nearly a copy of kpp_transport_s
1192     - there is no analogue to SurfaceTendencyS, so I have to use
1193       gPtr(of the surface layer) instead
1194    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1195    checkpoint50e_pre
1196    
1197    checkpoint50d_post
1198    o change kpp output from multiple-record state files to single-record state
1199      files analogous to write_state.F
1200    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1201      analogous to the cg2d-related output.
1202    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1203      so that writing to internal file fn (with length 512) fails.
1204    checkpoint50d_pre
1205    
1206    checkpoint50c_post
1207    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1208    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1209    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1210    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1211    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1212    
1213    checkpoint50c_pre
1214    Merging from release1_p13:
1215    o bug fix for pkg/seaice dynamic solver
1216    o Added SEAICE_initialHEFF to pkg/seaice
1217    
1218    checkpoint50b_post
1219    o store u*,v* in gU,V instead of in guNm1,gvNm1
1220    o in order to put the momForcing out of the Adams-Bashforth:
1221      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1222      to timestep.F
1223    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1224    o re-generate output for highly sensitive test-exp:
1225       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1226    
1227    checkpoint50b_pre
1228    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1229    o corrected CPP option mismatch in exf_Bulk... functions for case
1230      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1231    
1232    checkpoint50a_post
1233    o Bug fix for merging between c50 and KPP.
1234      ikey was passed from thermodynamics to kpp_calc via
1235      common block rather than being recomputed in kpp_calc,
1236      in contradiction with new key itdkey.
1237      New key ikppkey created, and tamc.h headers updated.
1238    
1239    checkpoint50
1240    - 2nd step of merge with ecco-branch:
1241      merge changes in ecco-branch back into main trunk
1242    - bug fix in find_alpha
1243    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1244    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1245    - merged some sliced AD support routines
1246    
1247    checkpoint49
1248    merged from ecco-branch:
1249    o exf:
1250      - Enable initialisation of forcing fields to constant
1251        (runtime) values.
1252      - in exf_getffields.F
1253        Reduce i-/j-loop to interior domain, discarding overlaps.
1254        That also fixes wrong TAF-key computations for key_1, key_2
1255        with bulf formulae.
1256      - exf_init.F modify #ifdef for exf_init_evap
1257      - exf_getffieldrec.F, ctrl_getrec.F
1258        The following INT-usages are not safe:
1259          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1260          fldcount = int(fldsecs/fldperiod) + 1
1261        and were modified.
1262    o autodiff: checkpoint_lev...
1263      - updated storing for bulk formulae (some arrays were missing)
1264      - added state for seaice package
1265      - synchronized with main branch
1266    o DIVA:
1267      Modif.s in
1268      - the_main_loop.F
1269      - the_model_main.F
1270      and added cost_final_restore.F cost_final_store.F
1271      o With these changes, it is possible to fully separate
1272        the first forward run to compute the cost function (mdthe_main_loop)
1273        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1274        into separate model executions.
1275        This enables better tuning of DIVA to given queue sizes.
1276      o Loss of cost function value in consecutive DIVA runs is
1277        fixed by storing to 'costfinal' file.
1278      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1279        beginning/end of adjoint integration is accounted for.
1280      The current changes apply to TAF-1.4.26.
1281      TAF has one remaining bug, requiring one manual change
1282      (see MITgcm manual).
1283    o cal: synchronized between MAIN and ecco-branch
1284    
1285    checkpoint48i_post
1286    o Changes to restore differentiability of code w.r.t. previous tag
1287      (mostly adding new routines to make list and replacing
1288      pressure by totPhiHyd).
1289    o Updated and merged grdchk package
1290      - has both ADM and TLM checks
1291      - works for single- and multi-proc.
1292      - output cleaned
1293      - worked successfully for parallel DIVA
1294    o genmake:
1295      - Adding -platform=SP4
1296      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1297    o Modif. for DIVA:
1298      ctrl_unpack should not be called in intermediate DIVA interval.
1299      (similar thing would apply for active files such as
1300      tbar, sbar, psbar, which should not be reinitialised;
1301      only relevant for ecco-branch)
1302    
1303    checkpoint48h_post
1304    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1305    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1306    o Added SEAICE_initialHEFF to pkg/seaice
1307    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1308    
1309    checkpoint48g_post
1310    --- EOS:
1311    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1312      store total Potential in totPhyHyd for diagnostics & EOS.
1313    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1314    --- Pressure/geopotential gradient:
1315    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1316    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1317      ( changes results of global_ocean_pressure )
1318    o NLFS + z-coord.: add eta*Rho' contribution.
1319    o accurate phiHyd when using interface-W at the middle between 2 centers
1320     ( changes results of ideal_2D_oce )
1321    o includes r* 2nd term in potential gradient.
1322    
1323    checkpoint48f_post
1324    Merging from release1_p12:
1325    o Modifications for using pkg/exf with pkg/seaice
1326      - improved description of the various forcing configurations
1327      - added basic radiation bulk formulae to pkg/exf
1328      - units/sign fix for evap computation in exf_getffields.F
1329      - updated verification/global_with_exf/results/output.txt
1330    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1331      (SBO) core products, including oceanic mass, center-of-mass,
1332      angular, and bottom pressure (see pkg/sbo/README.sbo).
1333    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1334      to avoid negative values in shallow regions.
1335      - updated verification/natl_box/results/output.txt
1336      - updated verification/lab_sea/results/output.txt
1337    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1338    o Added useSingleCpuIO option (see PARAMS.h).
1339    o Updated useSingleCpuIO option in mdsio_writefield.F to
1340      work with multi-field files, e.g., for single-file pickup.
1341    o pkg/seaice:
1342      - bug fix in growth.F: QNET for no shortwave case
1343      - added HeffFile for specifying initial sea-ice thickness
1344      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1345    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1346      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1347    o pkg/seaice:
1348      - adjoint-friendly modifications
1349      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1350    
1351    checkpoint48e_post
1352    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1353    o dynamics: change definition of computational domain & adapt mom_fluxform
1354      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1355    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1356        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1357        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1358        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1359        inverted_barometer solid-body.cs-32x32x1
1360      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1361    
1362    checkpoint48d_post
1363    o in preparation for r*:
1364     a) use pre-computed gradient of hydrostatic potential:
1365        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1366     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1367        => affects results of glob_oce_pressure (different truncation error)  
1368      update output.txt of ideal_2D_oce & global_ocean_pressure
1369    
1370    checkpoint48d_pre
1371    o in preparation for r*:
1372      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1373      pass the 2 comp. of the grad. as arguments to momentum S/R.
1374      but for the moment, only used if it does not change the results.
1375    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1376    
1377    checkpoint48c_post
1378    Modifications in treatment of initial flux forcing controls
1379    to avoid extra storing of flux fields.
1380    
1381    checkpoint48c_pre
1382    o Added tidal_basin_2d experiment (currently 1D!)
1383    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1384    
1385    checkpoint48b_post
1386    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1387     (modification to pressure gradient not yet implemented)
1388    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1389      (for U & V) that are used for vertical advection of momentum.
1390    
1391    checkpoint48a_post
1392    o In preparation for r*, use temp. array to compute vertical transport
1393       in flux-form momentum pkg. => change results of few test-exp.
1394      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1395                        lab_sea, natl_box & plume_on_slope
1396    
1397    checkpoint48
1398    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1399    
1400    checkpoint47j_post
1401    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1402    o moved adexch from forward_step to addummy_in_stepping
1403    o added exch in ctrl_map_...
1404    o aveFreq.=0. at end of cost_final to avoid overwrite in
1405      reverse checkpointing loop
1406    o Yet more changes in gmredi:
1407      * adgmredi_calc_tensor
1408        avoiding all recomputation of gmredi_slope_limit
1409      * adgmredi_x/y/rtransport
1410        added flag for excessive storing to avoid recomp. of
1411        u/v/rtans, dTdx/y/z
1412        -> this is not really necessary and very memory-consuming
1413      * adgmredi_slope_psi:
1414        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1415      * gmredi_slope_limit
1416        re-activated full calculation of taperfct for case 'ac02'
1417    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1418    
1419    checkpoint47i_post
1420    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1421    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1422      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1423    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1424    o gmredi: fix few bugs.
1425    
1426    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1427    This will be a good checkpoint to plug into the ecco-branch.
1428    o few modif.'s to get latest version adjointed
1429      (mainly kick out code in ini_linear_phisurf)
1430    o modif's to run adjoint with exactConserv
1431    o case GM_BOLUS_ADVEC should be cleaned
1432      S/R gmredi_slope_psi should be cleaned
1433    o verification/carbon now has exactConserv=.TRUE.
1434    
1435    checkpoint47g_post
1436    o time-average AIM output: becomes independent from statvars time-average
1437      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1438    o After TAF bug fix:
1439      Tested adjoint of gmredi package.
1440      Tests were done with checkpoint47 rather than with latest
1441      checkpoint47f_post since the latter is broken for the adjoint
1442      verification/carbon/ contains both ADM and TLM gradient checks.
1443    Here they are, before they get changed/lost/stolen.
1444    Mostly modif.'s to fix numerical sensitivities.
1445    Gradient checks OK for
1446    - GM_taper_scheme:
1447      * clipping
1448      * ac02
1449      * linear
1450      * glw91
1451      * dm95
1452      * ldd97
1453    - GMREDI_OPTIONS:
1454      * GM_VISBECK_VARIABLE_K
1455      * GM_NON_UNITY_DIAGONAL
1456      * GM_EXTRA_DIAGONAL
1457      * GM_BOLUS_ADVEC
1458    in conjunction with data.gmredi parameters to be checked in
1459    in a few minutes under verification/carbon/code/
1460    
1461    checkpoint47f_post
1462    Merging from release1_p10:
1463    o modifications for using pkg/exf with pkg/seaice
1464      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1465        and SEAICE_EXTERNAL_FLUXES
1466      - pkg/exf CPP options EXF_READ_EVAP and
1467        EXF_NO_BULK_COMPUTATIONS
1468      - usage examples are Experiments 8 and 9 in
1469        verification/lab_sea/README
1470      - verification/lab_sea default experiment now uses
1471        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1472    
1473    checkpoint47e_post
1474    o created a tag prior to creating a branch
1475    
1476    checkpoint47d_post
1477    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1478      at the bottom boundary had an erroneous half slip boundary condition
1479    o added bottom drag and no slip boundary condition capabilities to
1480      oceanic pressure coordinates code
1481    o added new verification experiment global_ocean_pressure, this experiment is
1482      also described in the tutorial section of the manual
1483    checkpoint47d_pre
1484    
1485    checkpoint47c_post
1486    o Added a verification experiment for a global cubed-sphere ocean run
1487      -  verification/global_ocean.cubed32x32x30
1488      -  uses pkg/therm_seaice and pkg/bulk_forcing
1489    
1490    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1491    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1492      when using P-coordinate; only implemented for atmospheric config.
1493    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1494      NOTES: requires option NONLIN_FRSURF to be "#define".
1495    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1496    
1497    checkpoint47b_post
1498    Merging from release1_p9:
1499    o pkg/seaice
1500      - removed GOTO's and added taf directives
1501      - double precision constants to reduce the g77 (Linux)
1502        to F77 (SGI) differences reported in release1_p8
1503    o tools/genmake
1504      - added SGI options
1505    o verification/testscript
1506      - updated to that of checkpoint47a_post
1507    o verification/global_ocean.90x40x15/input/eedata
1508      - modified for SGI f77 compatibility
1509    o verification/lab_sea
1510      - added description of sea-ice model
1511      - added missing matlab routines
1512      - added test of thermodynamics parallelization
1513    
1514    checkpoint47a_post
1515    o new pkg: aim_v23
1516     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1517       for now, keep the same surface forcing as before.
1518     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1519     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1520     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1521    o add diagnostic of surface correction term in monitor output
1522    
1523    o bulk_force and therm_seaice
1524    - Two packages:  bulk_force (Bulk forcing)
1525      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1526    - Earlier integration from Stephaine Dutkiewicz
1527      and Patrick Heimbach.
1528    - Two ifdef statements for compile time,
1529       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1530    
1531    checkpoint47
1532    differentiable version of checkpoint46n_post
1533    o bug fix in quasihydrostaticterms
1534    o * "clean" adjoint code (in terms of extensive recomputations)
1535        can now be obtained for all GMREDI options (i.e. for
1536        - GM_VISBECK_VARIABLE_K
1537        - GM_NON_UNITY_DIAGONAL
1538        - GM_EXTRA_DIAGONAL
1539        - GM_BOLUS_ADVEC )
1540      * However, wrong gradient check problem remains unsolved.
1541      * New CPP options have been introduced for different
1542        tapering schemes
1543    o external_fields_load now part of differentiation list
1544    o pressure needs multiple storing;
1545      would be nice to have store_pressure at beginning or
1546      end of forward_step, e.g. by having phiHyd global (5-dim.)
1547      (NB: pressure is needed for certain cases in find_rho,
1548      which is also invoked through convective_adjustment).
1549    o recomputations in find_rho for cases
1550     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1551    o #define ATMOSPHERIC_LOADING should be differentiable
1552    o ini_forcing shifted to begining of initialise_varia
1553    o Incorporating QNVS line search routines into MITgcm
1554      (this is separate code, and therefore not under pkg)
1555      lsopt/, optim/
1556    o Updated verification/carbon/
1557      - #define GM_VISBECK_VARIABLE_K
1558      - GM_taper_scheme    = 'ldd97'    
1559    
1560    checkpoint46n_post
1561    Merging from release1_p8:
1562    o verification/natl_box:
1563      updating new external_fields_load routine
1564    o New package: pkg/seaice
1565      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1566      The sea-ice code is based on Hibler (1979-1980).
1567      Two sea-ice dynamic solvers, ADI and LSR, are included.
1568      In addition to computing prognostic sea-ice variables and diagnosing
1569      the forcing/external data fields that drive the ocean model,
1570      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1571      The implied surface heat flux is then stored in variable
1572      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1573      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1574      non-local transport term.  Because this call precedes model
1575      thermodynamics, temperature under sea-ice may not be "exactly" at
1576      the freezing point by the time theta is dumped or time-averaged.
1577      N.B.: fairly large differences in accuracy occur across
1578            different platforms/compilers; comparison between
1579            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)

1588    o GAD:
1589      - generated new common blocks to account for call of
1590        same gad routines with differing traceridentities
1591        (needed to modify tracerIdentity indices in GAD.h)
1592      - generated separate common blocks for case useCubedSphereExchange
1593        (Department of Futurology)
1594      - parameter lists to gmredi_?transport: added tracerIdentity
1595      - added new key indices to tamc.h
1596    o external_fields_load:
1597      - added this routine to TAF list
1598      - needed to make some common blocks global and additional storing
1599        along the same lines as exf package (checkpoint_lev?_directives.h)
1600    o exf:
1601      updated external forcing package
1602      - bug fixes carried over from ecco-branch
1603        (missing OBCS_OPTIONS.h in two routines)
1604      - enable easy to use "no forcing".
1605      - added exf I/O for atmospheric loading
1606      - added exf I/O for runoff data
1607      - transfered scaling between exf <-> MITgcm to exf namelist
1608    o Adding new verification experiment global_with_exf.
1609      This verification experiment is almost identical to the
1610      global_ocean.90x40x15 experiment, except that it uses
1611      the exf (and cal) package instead of the
1612      external_fields_load routine (cf README file).
1613    
1614    checkpoint46m_post
1615    o modified testscript to return -- when there are no lines of "%MON" output
1616    o added new flag "quasiHydrostatic" for QH mode
1617      and new routine quasihydrostaticterms()
1618    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1619      New routine: mom_u_coriolis_nh()
1620    o fixed sign of non-hydrostatic metric terms in u and v equations.
1621      Depend on correct sign of gravitySign.
1622    o added work.pc* to .cvsignore in aim directories using ifc
1623    o introduced flag for controllin non-hydrostatic metric terms
1624    o removed gravitySign from PARM04
1625    o switched to g77/ifc from pgf77 in aim experiments
1626    
1627    checkpoint46l_post
1628    o made convective adjustment work with pressure coordinates:
1629     - changed the direction of k-loop in convective_adjustment.F for the
1630       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1631     - adjusted the reference pressure k-index in convective_adjustment.F
1632     - adjusted the convection condition in convect.F (in analogy to
1633       calc_ivdc.F)
1634     - convective_adjustment no longer computes anything on the halos
1635     - removed the warnings about negative salinity from find_rho.F and
1636       find_alpha.F; instead the new routine look_for_neg_salinity, called
1637       at the beginning of find_rho, find_alpha, and find_beta, does a
1638       check of the entire slice, if CPP-option
1639       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1640    checkpoint46l_pre
1641    
1642    checkpoint46k_post
1643    o fixed the verification/global_ocean.90x40x15 experiment:
1644     - new bathymetry (the world according to A., JMC, and M.)
1645     - new initial fields and forcing fields (*.bin files)
1646     - new POLY3.COEFFS (for the next release one should switch to a full
1647       equation of state: JMD95P or MDJWF)
1648     - fixed several errors and redundancies in the data file
1649     - experiment uses looped cells
1650     - added matlab directory with diagnostic scripts for plotting of output
1651    
1652    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1653     - read AIM physics parameters from a file (data.aimphys)
1654     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1655    
1656    checkpoint46j_post
1657    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1658    o move wVel computation at the end of the time step, in S/R integr_continuity
1659    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1660    o update timeave pkg for wVel diagnostic.
1661    checkpoint46j_pre
1662    
1663    checkpoint46i_post
1664    o Clean up AIM package (and keep the results unchanged):
1665      include CPP_OPTION and use IMPLICT NONE in all routines ;
1666      declare all the variables _RL ; use _d 0 for all numerical constants.
1667      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1668    
1669    checkpoint46h_post
1670    o cleaned up the use of rhoNil and rhoConst.
1671      - rhoNil should only appear in the LINEAR equation of state, everywhere
1672        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1673        and the dynamical equations are all divided by rhoConst
1674    o introduced new parameter rhoConstFresh, a reference density of fresh
1675      water, to remove the fresh water flux's dependence on rhoNil. The default
1676      value is 999.8 kg/m^3
1677    o cleanup up external_forcing.F and external_forcing_surf.F
1678      - can now be used by both OCEANIC and OCEANICP
1679    checkpoint46h_pre
1680    
1681     Added code to convert surface volume flux (fresh water) into
1682     a mass flux when using P coordinates in the ocean (OCEANICP).
1683     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1684    
1685    checkpoint46g_post
1686    o Include a new diagnostic variable phiHydLow for the ocean model
1687      - in z-coordinates, it is the bottom pressure anomaly
1688      - in p-coordinates, it is the sea surface elevation
1689      - in both cases, these variable have global drift, reflecting the mass
1690        drift in z-coordinates and the volume drift in p-coordinates
1691      - included time averaging for phiHydLow, be aware of the drift!
1692    o depth-dependent computation of Bo_surf for pressure coordinates
1693      in the ocean (buoyancyRelation='OCEANICP')
1694      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1695        Theta, Salinity, and Pressure in the parameter list. This routine is
1696        presently contained in find_rho.F. This routine does not give the
1697        correct density for 'POLY3', which would be a z-dependent reference
1698        density.
1699    o cleaned up find_rho
1700      - removed obsolete 'eqn' from the parameter list.
1701    o added two new verification experiments: gop and goz
1702      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1703    checkpoint46g_pre
1704    
1705    checkpoint46f_post
1706    o Enable tangent linear (forward mode) gradient checks:
1707      - extended active file handling to g_... files
1708      - added TANGENT_SIMULATION to theSimulationMode
1709      - extended grdchk package accordingly
1710    o added tangent linear setup in verification/carbon/code_ftl
1711    o added adjoint setup in verification/front_relax/code_ad
1712    
1713    checkpoint46e_post
1714    o Added new equation of state -> MDJWF
1715      - EOS of McDougall et al., 2002, JAOT, submitted
1716      - caveat: the equation of state is only valid for a smaller (more
1717        realistic?) range of values than JMD95P/Z and UNESCO
1718      - added masks to the calculation of pressure in store_pressure
1719      - added more check values for density in check_eos (ini_eos.F), some of
1720        the old check values are out of the range of the MDJWF-eos, so don't
1721        expect perfect matches for those
1722    checkpoint46e_pre
1723    
1724    checkpoint46d_post
1725    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1726      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1727      case of pressure coordinates. eosType='JMD95Z' in
1728      combination with buoyancyRelation='OCEANICP' now causes an error.
1729    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1730      in find_alpha/beta.
1731    checkpoint46d_pre
1732    
1733    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1734      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1735    
1736    checkpoint46c_post
1737    o Changes necessary for ocean in p-coordinates
1738     -  Added new buoyancy relation = 'OCEANICP'
1739     -  Added new parameters = gravitySign (this used to be contained inside
1740        the factor dRdZ which I added when we first switched to R coordinates).
1741     X GM/Redi is not compatible (yet)
1742     X bottom drag and no-slip need to be debugged.
1743    checkpoint46c_pre
1744    
1745    checkpoint46b_post
1746    o Added new equation of state -> JMD95Z and JMD95P
1747      - EOS of Jackett and McDougall, 1995, JAOT
1748      - moved all EOS parameters into EOS.h
1749      - new routines ini_eos.F, store_pressure.F
1750    o Added UNESCO EOS, but not recommended because it requires
1751      in-situ temperature (see JMD95)
1752    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1753      unesco.f to be used with POLY3
1754    checkpoint46b_pre
1755    
1756    checkpoint46a_post
1757    o Added (atmospheric) pressure loading
1758      - new field in FFIELDS.h, etc...
1759      - new cpp flag ATMOSPHERIC_LOADING
1760    o Changed hFacC to _hFacC in calc_phi_hyd.F
1761    o Added SHORTWAVE_HEATING to some files for consistency
1762    checkpoint46a_pre
1763    
1764    checkpoint46
1765    further merges from release1_p5
1766    o new ctrl package
1767      - adopted from ECCO environment to enable optimization
1768      - added Eliassen Palm fluxes to controls
1769    o added Eliassen Palm flux controls to gradient check package
1770    o cost package
1771      - Compatible with new ctrl package
1772      - added Eliassen Palm cost hooks
1773      - modif's of existing cost functions
1774    o Adjoint-related bug fixes in kpp:
1775      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1776      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1777    o autodiff package
1778      - flow directives:
1779        + new for S/R do_the_model_io
1780        + enhanced for S/R checkpoint
1781        + new gmredi.flow
1782      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1783        disable adcommon.h/g_common.h by default.
1784      - fixed problem for adjoint of global_max
1785    o modified verification/carbon/
1786    o New setup for adjoint of global_ocean
1787    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1788    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1789    o incorporated hooks for sponge layer code (external_forcing.F)
1790    
1791    checkpoint45d_post
1792    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1793    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1794      (affects plume_on_slope "cg2d" output)
1795    o add new parameter deltaTfreesurf for free-surface time stepping
1796    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1797    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1798    o change phiMin in exp1 (to agree with documentation)
1799    o add new flags:
1800     - T,S forcing inside/outside Adams-Bashforth
1801     - turn off temp,salt advection and/or forcing
1802     - for each tracer, define internal flag for multiDimAdvection & A-B
1803    o monitor: change definition of KE to check conservation of Energy
1804    
1805    checkpoint45c_post
1806    o Removed f90 comments ("!")
1807    o Modified initialisations to enable exf package for MITgcm
1808      (without invoking ECCO_PACKAGE).
1809    o modifications to gradient check package (Martin Losch)
1810      - enable centered differences
1811      - modified format of standard output
1812    
1813    checkpoint45b_post
1814    o cleaned exchange calls in cg2d
1815    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1816    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1817      to configure barotropic setup (Martin Losch)
1818    o moved some initialisations within bi,bj loop in dynamics
1819      (TAF flow dependency)
1820    o in initialise_varia, moved call packages_init_variables
1821      before convective_adjustment_init
1822      (corresponding adjustment of TAF tape initialisation).
1823    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1824    
1825    checkpoint45a_post
1826    o compute Rho over the whole domain (extend iMin,jMin indices)
1827    o specific exchange for X-slice domain (case Ny=1)
1828    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1829    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1830    
1831    checkpoint44h_post = checkpoint45
1832    o Fix to restore differentiability:
1833      place at which packages_init_variables is called in
1834      initialise_varia is crucial for reverse control flow.
1835    o modifications in GMRedi to enable stable adjoint
1836      (corresponding modif's in thermodynamics, dynamics)
1837    o added missing hook for sponge layer code in external_forcing
1838    o modified test cost functions
1839    o storing in gad_advection (plus removal of write(0,*)!
1840    o missing headers TR1.h added in convective_adjustment routines

1842      (conflict on some platforms, e.g. IBM SP3)
1843    o modified carbon verif.
1844    
1845    checkpoint44h_pre
1846    o vertical grid option: allow to put the Interface at the middle between
1847      2 cell-centers ; replace delZ in pkg/kpp by drF.
1848    o GM Advective form: Tracers are advected using the residual transport (=
1849      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1850    
1851    checkpoint44g_post
1852    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1853      results) ; ifdef missing in thermodynamics.F
1854    
1855    checkpoint44f_pre,checkpoint44f_post
1856    o added PTRACERS package
1857      This allows an arbitrary number of passive tracers to be integrated
1858      forward simultaneously with the dynamicaly model.
1859      + Implemented so far:
1860        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1861        - I/O and checkpointing
1862        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1863      + Not implemented so far:
1864        - KPP
1865        - OBCS
1866      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1867        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1868        line in data.pkg.
1869      + This package is disabled by default since it increases storage.
1870    
1871    
1872    o testscript: added -cleanup option
1873    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1874                 b) enable to filter 2D fields.
1875    
1876    checkpoint44e_pre,post
1877    o re-wrote convective adjustment to use pre-calculated weights
1878      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1879      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1880      Original calls to convect() still in place.
1881    
1882    chkpt44d_pre,post
1883    o added missing EXCLUDE_MONITOR flags
1884    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
1885      (incompatible typ in MIN/MAX expressions caused problems
1886      on IBM SP3)
1887    o in genmake added variable MAKEDEPEND
1888      plus resetting for case SunOS
1889    o added timer_stats.c routine for IBM SP3
1890    o removed variables in dynamics
1891    !!! I forgot to create tag chkpt44d_pre !!!
1892    !!! But chkpt44d_pre = chkpt44c_post    !!!
1893    
1894    o real fresh water flux implemented with non-linear free-surface.
1895    
1896    chkpt44c_pre,post
1897    o few fix (mask in shap_s2, EmPmR in external_field_load,
1898      USE_NATURAL_BCS in solve_for_P);
1899    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
1900    
1901    checkpoint44b_pre/_post

1910                   added directive for divided adjoint in the_main_loop
1911      - pkg/mdsio: added mdsio_gl_slice
1912

1934    o New store directives for multi-dim. advection schemes
1935      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
1936      * new common block and key passkey

1945    
1946    checkpoint40
1947    o moved calc_gs, calc_gt and calc_tr1 back to model/src
1948    o added FLT (floats) package from Arne along with demo. experiment
1949    o re-arranged Adams-Bashforth scheme for tracers to allow easier

1965    checkpoint40pre8
1966    o new package rw/
1967      Added method for dumping intermediate local arrays:
1968      mdsio_writetile - same as mdsio_writefield except works from inside
1969                        bi,bj loop
1970      mdsio_writelocal - same as mdsio_writetile except works for local
1971                         arrays
1972      write_local_r? - higher-level wrapper for mdsio_writelocal
1973      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1974      Example given at end of mom_vecinv.F that dumps some local arrays.
1975    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1976      control flux-form versus vector invariant code.
1977      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1978      or genmake -DISABLE ...
1979    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1980      (additional storing is now needed for case vecinv;
1981      currently nothing implemented to switch this storing off
1982      in case fluxform is used since no CPP flag available).
1983    
1984    checkpoint40pre7
1985    o bug fix in dynamics.F
1986      calc_viscosity called before k=1,Nr loop.
1987    o added some #ifdef's ALLOW_PASSIVE_TRACER
1988    o cleaned initialisations in ctrl_map_ini
1989      related to TAF
1990    
1991    checkpoint40pre6
1992    o split dynamics into thermodynamics & dynamics
1993    o corresponding split of calc_diffusivity into
1994      calc_diffusivity, calc_viscosity
1995      (kpp_calc_diff, kpp_calc_visc).
1996    o Added diffkr, kapgm to control variables
1997    o bug fix in gmredi_slope_limit for ldd97
1998    
1999    checkpoint40pre5
2000    o proper initialization of Adams-Bashforth time stepping
2001      + uses forward step for very first step of model (iter=0)
2002    o re-generated *all* output since almost all output is modified by this
2003      change (sorry but we've been putting this one off for about 2 years)
2004      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
2005        *not* regenerated since they are already out of date and I don't
2006        want to create the impression that they are suddenly working.
2007    o removed KAP stuff for DEC's
2008    o modified/added many .cvsignore files in */code and */input
2009    o added new expt "solid-body.cs-32x32x1"
2010      + this uses an alternative form of ini_curvilinear_grid.F which
2011        is not necessarily any better than the current one...
2012    
2013    checkpoint40pre4
2014    o added re-initialisations of utrans,vtrans,rtrans in
2015      calc_common_factors which are crucial for TAF.
2016    o extended iMin,jMin range for calc_common_factors,
2017      calc_diffusivity
2018    o added option ALLOW_PASSIVE_TRACER
2019    o a few minor updates and fixes
2020    
2021    checkpoint40pre3
2022    o created calc_gtr1.F for gad package
2023    o split the_main_loop and re-introduced forward_step
2024    o some recomputations of nIter0 for TAMC
2025    
2026    checkpoint40pre2
2027    o Updated to latest branch of AJA, JMC
2028    o Added gradient check package
2029    o Added routines for passive tracer handling
2030    o Added carbon sequestration sensitivity experiment
2031    
2032    checkpoint39
2033     o Modifications and fixes to support TAMC
2034       (mainly missing or wrong directives)
2035     o Corrected common blocks when fooling TAMC to produce adjoint I/O
2036       in addummy_in_stepping
2037     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
2038     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
2039     o Included following packages:
2040       cal: calendar
2041       exf: external forcing
2042       ecco: essential routines to control use of cal, exf
2043             (NB: this is not the full ECCO environment)
2044     o disabled some packages by default in genmake
2045    
2046  checkpoint38  checkpoint38
2047   o see notes_c37_adj.txt   o see notes_c37_adj.txt
2048   o corrected wrong layer index in external_forcing_t   o corrected wrong layer index in external_forcing_t
