3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
7    o make genmake2 more portable by using ".$FS" instead of ".f" for more
8      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
9    o add coordinate variables to the MNC output from the diagnostics package
10    o change MNC-flags default value: true when useMNC=TRUE
11    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
12      the ability (off by default) to read the grid information using MNC
13    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
14    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
15    o do snap-shot diagnostics at the middle of the time-interval (instead of
16      at the end).
17    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
18      new test for AIM with thSIce + slab-ocean
19    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
20    o move state variable diagnostics to the beginning of the time step ;
21      (note: still needs some work specially for snap-shot diagnostics)
22      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
23    
24    checkpoint57c_post
25    o Change testing option (-ieee) to get closer agreement between g77 & ifort
26    o generate new output.txt files on faulks with g77 & the new -ieee option
27    checkpoint57c_pre
28    
29    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
30      update output.txt of exp. global_ocean.90x40x15
31    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
32      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
33    o add saltFlux(+File) forcing capability with periodicExternalForcing
34    o allow to use pkg diagnostics for GM-Redi & ThSIce output
35    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
36    o improvements for the MNC output from DIAGNOSTICS:
37      - correct handling of the unlimitied dimension
38      - all dims now have associated coordinate variables
39      - variables located at U, V, and Corner ("Z") points are now written
40        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
41        *all* data points are output
42    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
43    o added pkg/seaice/seaice_monitor.F
44    o mdsio_readfield.F can now read files visible only to master MPI process.
45    o pkg/seaice: some test code for ice-modified ocean stress
46    o exf_getffields interpolation defaults to bilinear for all scalar forcing
47      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
48      spurious negative numbers for precipitation and humidity.  Will cause
49      some small numerical differences for integrations using pkg/exf/exf_interp.F.
50    o pkg/ctrl/
51      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
52        May be enabled via doPackDiag
53      *  introduce z-scaling of
54         + gradient (doZscalePack) and
55         + control (doZscaleUnpack)
56    o pkg/mdsio/
57      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
58      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
59    
60    checkpoint57b_post
61    o simplify options in diagnostics_fill arguments (remove weird combinations)
62    o fix MNC coordinate variables so that they now contain per-face index
63      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
64      general, EXCH2 grids are only aligned to a "local" coordinate system
65    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
66    o Implement instantaneous output within pkg diagnostics:
67      setting a negative frequency in data.diagnostics produces
68     "snap-shot" output (as opposed to time-average if freq > 0)
69    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
70      NOTE: change ptracer diagnostics name: use 2 characters to work with
71            more than 9 tracers. Add also diagnostics of advect & diffus flux.
72    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
73      becomes the coordinate variable for the 'T' dimension
74    o add CF-style coordinate variables to MNC
75      - just a first cut:  numbers are meaningless on the cubesphere and
76        missing along the T axis but otherwise it works!
77    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
78    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
79    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
80      this is based directly on what the model compute, so that the content of
81      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
82    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
83    o clean up build options files for SunOS, in particular
84      - remove -traditional from xmakedepend
85      - change -xarch=v9 to -xarch=native for f77
86      - restore use of make (not gmake)
87      - add CC=gcc if using g77
88    o changes per discussion of AM, JMC, & EH3 today:
89      - move redundant "grid" variables out of "state" -- in preparation of
90        creating proper CF-style coordinate variables and in recognition
91        that any/all grid variables can be easily copied (eg. w/NCO) from
92        the grid files into any of the other NetCDF files
93      - *always* output grid variables with MDSIO (this will eventually be
94        changed)
95      - output MNC grid file if useMNC is true
96    o every instance of _END_MASTER() has been found and replaced with
97      _END_MASTER( myThid ) in order to satisfy certain picky Sun
98      preprocessors
99    o re-arrange diagnostics pkg initialisation:
100     - allow each package to extend the available diagnostics list
101     - add some checking and fix small problems (multi-threaded, ...)
102     - new S/R diagnostics_fill (replace fill_diagnostics):
103       look through the short list of active diag. (instead of the long list)
104       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
105    
106    checkpoint57a_post
107    o this set of changes restores TAMC compatibility
108      tested for global_ocean.90x40x15 adjoint on trough
109      (what a pain)
110    
111    checkpoint57a_pre
112    o some modifs in tools/build_options for sunos
113    o call ctrl_pack for ctrl at end for optimcycle=0
114    
115    checkpoint57
116    o add horizontal bi-harmonic viscosity for vertical velocity
117      - new parameter viscA4W (defaults to viscA4)
118      - affects only non-hydrostatic code
119      - to be done: no-slip lateral boundary conditions
120    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
121    o implement Implicit Vertical advection for pTracers
122    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
123      (implemented also for implicit vertical diffusion & advection)
124    o OBCS: extend application of tracer open boundary conditions
125      to a strip beyond the boundary of width Olx/Oly
126    o add call monitor to TAF set of required calls (flow directives)
127      and include in natl_box_adjoint
128    o untangle a few ifdefs related to cost, ctrl, autodiff
129      untangel a few ALLOW_ECCO_OPTIMIZATION
130    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
131      (theta2, salt2 in ecco_cost_weights)
132    
133    checkpoint56c_post
134    o OBCS as control variables
135      - update ctrl_ad_diff.list, obcs_ad_diff.list
136      - remove balance of obcs controls from default
137      - fix index bug nobcs in ctrl_init
138      - fix dummy fields filen in ctrl_pack
139      - add dummy weights for obcs
140    o lsopt: comment out fort.94 output
141    o optim:
142      - remove unnecessary header files
143      - adjusted namelists
144      - add xerbla.F to Makefile
145    o exf:
146      - multiple modifications of exf_check_range
147      - unit change in exf_init_runoff from [m/year] to [m/s]
148    o mdsio:
149      - i/o-vector change debugLevel from debLevA to debLevB
150    
151    checkpoint56b_post
152    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
153      is called from DO_THE_MODEL_IO
154      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
155      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
156      - clean up PTRACERS_WRITE_TIMEAVE a little
157    o add another verification experiment that tests both the cfc-pkg and
158      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
159      reactive tendencies treated inline with regular timestepping
160    o testreport previously did a lousy job of comparing small numbers, so
161      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
162      implemented in the little c-progam tmp_cmpnum.c which is embedded in
163      testreport.
164    o ptracers_monitor: bug fix for MPI
165    
166    checkpoint56a_post
167    o GCHEM: finish reorganizating the package
168      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
169        (introduces another 3D-array for each passive tracer, but only if
170        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
171        gchemTendency is not needed because the timestep is done separately)
172      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
173      - GCHEM is now---more or less cleanly---separate from PTRACERS
174      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
175        so clear to me how that should be done in a general way.
176    o CFC: improve formatting of output in CFC_ATMOS
177    o PTRACERS:
178      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
179        that ALL experiments with ptracers enable can be checked. This makes
180        GCHEM_MONITOR obsolete.
181      - include a runtime parameter PTRACERS_monitorFreq that defaults to
182        monitorFreq
183      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
184    o add PTRACERS (PTR0[1-5]) to testreport output
185    o exf_check_range:
186      * default changed to .TRUE.
187      * will check values for niter0 if debLevA, every timestep if debLevB
188      * STOP in exf_check_range if 'out of range'
189      * range chosen generous to allow for potential extema
190      TBD: a version with stricter range
191           permitted range would be runtime parameters
192    o GMredi:
193      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
194      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
195      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
196    o GCHEM:
197      - move call to GCHEM_FORCING_SEP, so that it is now called before
198        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
199      - introduced a useGCHEM runtime flag and applied it everywhere.
200      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
201        this flag is now only visible within GCHEM-pkg routines.
202      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
203        be replaced by a 3D array that is computed before thermodynamics; for
204        this, the tracer ID iTracer had to be included into the parameter list
205        of ptracers_forcing
206      - set up forward_step to call gchem_forcing, that will replace
207        gchem_forcing_int in ptracers_forcing
208      - cleaning up
209    o small cleaning of exch2: remove files that are also in eesupp/src
210    
211    checkpoint56
212    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
213    o mnc: cleanup "full" files--fixes out-of-memory problem
214    o ECCO-GODAE
215      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
216      * fully merged and updated from SIO code
217        windstress sign change affects
218        - exf_inscal_[u/v]stress
219        - sign of xx_tau[u/v] adjustments
220        - signs in cost_scat
221      * ctrl_get_gen: avoid update of tau[u/v] for first few days
222      * natl_box_adjoint updated and compressed
223      * 2-level checkpoint switch added
224        (tested in EXP. 1 of natl_box_adjoint)
225      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
226    o SVD
227      * first complete, non-hacked version for SVD calculations
228      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
229        performed via direct access files admtlm_vector.it????
230        (via ctrl_[un]pack)
231      * optimcycle is used for ARPACK iteration counter
232        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
233      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
234        and add linear transforms where necessary
235      * controls are initial/final SST, SSS (can be extended; need to check
236        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
237    o mdsio: filename info to both stderr, stdout
238    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
239      from sign change
240    
241    checkpoint55j_post
242    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
243      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
244    o add consistent build directories and .cvsignore files to verification
245    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
246    o make all subroutines 30 or less characters in length for certain older
247      compilers to work (a thorough search only turns up two routines in
248      pkg/ptracers)
249    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
250      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
251    
252    checkpoint55i_post
253    o change arrays for total vertical diffusivity (2.D if explicit,
254      3.D if implicit) ; each ptracer uses its own background value.
255    o added mnc/NetCDF output capability to ocn_compon_interf
256      - added bits to verification/cpl_aim+ocn so that it can run on
257        ITRDA and other clusters without the mpirun "-wd" option
258    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
259      configuration
260    o give MNC the ability to create additional files rather than
261      exceeding a specified file size limit "MNC_MAX_FILESIZE"
262      - the default is just less than 2GB which is a practical limit
263        on many systems
264    o Compute the non-local term using either KPP vertical diffusivity (=default)
265       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
266    
267    checkpoint55h_post
268    o add verification test "vermix"
269    o remove all the *_ioinc flags and replace with the single global
270      outputTypesInclusive flag
271    o allow to set a vertical profile of vertical diffusivity for T & S
272    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
273    o useMNC moved from data.mnc to data.pkg
274    
275    checkpoint55g_post
276    o Renaming carbon AD experiments to comply with testreport conventions
277    o Updating adjoint of Held-Suarez hs94.1x64x5
278    o Fixing directives for non-ECCO forward_step, after ECCO directives
279      have been fixed to avoid recomp. of do_oceanic_phys
280      Works well for global_ocean.90x40x15,
281      but recomp. issue remains for carbon
282    o Updating adjoint output for natl_box_adjoint after
283      pkg/ecco has been modified (see taga c55d_post)
284    
285    checkpoint55f_post
286    o rename to timeave_init_fixed
287    
288    checkpoint55e_post
289    o some delicate re-shuffle of store directives to avoid one
290      extra call of do_oceanic_physics
291      affects ecco_the_main_loop.F, do_oceanic_physics.F
292      checkpoint_lev1_directives.h
293    o NB: this may break global_ocean adjoint temporarily,
294      but it is clear how to fix it. Will do later, need this now.
295    
296    checkpoint55d_post
297    o ECCO specific cost function terms (up-to-date with 1x1 runs)
298    o ecco_cost_weights is modified to 1x1 runs
299    o modifs to allow observations to be read in as
300      single file or yearly files
301    o enable to read exf forcing fields as either
302      single file or yearly files (flag useExfYearlyFields)
303    checkpoint55d_pre
304    
305    o switch between 2-level and 3-level checkpointing
306    o add ability of MNC to write local and "partial" (eg. 2D slices where
307      the full 3D field is never actually stored) arrays to NetCDF files
308      with the correct (that is, the complete multi-dimensional) set of
309      array indicies
310      - used in mom_vecinv() to write the diagFreq output
311      - tested (demonstrated) in verification/aim.5l_cs
312    o further mnc-ification
313      - add verification/lab_sea to the list with mnc setups
314      - fix undefined mnc v-names in cd_code
315      - add kpp to mnc output (both snapshot and timeave)
316    o non-hydrostatic code
317      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
318        in calc_gw.F
319      - defaults to viscAh
320      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
321        friction or Leith) in non-hydrostatic mode, as long as there is
322        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
323    o pkg/cost
324      extend simple cost functions to treat time mean quantities
325      (T,U,V) via cost_accumulate_state from cost_tile
326    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
327        be 2 times larger than the minimum size the advection scheme requires.
328        now get a perfect conservation of salt in advect_cs test-exp (updated)
329    o GGL90 (Gaspar's TKE mixed layer)
330      - add horizontal diffusion of TKE, requires exchanges in
331        do_fields_blocking_exchanges, horizontal diffusivity is zero by
332        default. In OPA there is no horizontal diffusion of TKE but the
333        mixing coefficients are computed from a horizontal average of TKE of
334        6 points or so. I think that diffusion has a little more physical
335        justification.
336      - clean up ggl90_calc in the hope of reducing memory usage (this hope
337        was in vain)
338      - mask tke-variable in ggl90_init
339    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
340    o fix biharmonic diffusion on CS-grid.
341    o more obcs stuff
342      - added obcs_external_fields_load as an alternative to the EXF-pkg option
343        for reading boundary values. This routine is called from
344        obcs_prescribe_read
345      - updated obcs_check
346      - changed sponge layer relaxation parameter units for days to seconds
347      - turned off sponge layer by default
348      - changed argument list of OBCS_CALC to myTime+deltaTclock
349      - fixed about 35 bugs in obcs_external_fields_load
350    
351    checkpoint55c_post
352    o obcs stuff
353      - new runtime flags useOBCSprescribe, useOBCSbalance
354      - re-arranged obcs_calc
355      - moved exf_getobcs to obcs_prescibe_read
356        obcs_prescibe_read is called after ORLANSKI stuff
357        and independent of it (executable can contain all).
358      - updated obcs_check
359      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
360        These may be necessary only if tangential velocities are
361        prescribed at OB, not sure, needs testing.
362    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
363      which simplifies the calls and passes the ifc check-bounds test
364    
365    checkpoint55b_post
366    o add a 2D scalar, Z location, exchange_2 routine.
367    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
368      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
369      affects advect_cs results (for the wrong reason): update output.txt
370    o use a more standard discretization for biharmonic viscosity ;
371     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
372      affects results of dome set-up: update output.txt
373    o fix gad_advection.F (CubedSphere part), back to version 1.23
374    o fix bug in mom_vi_del2uv.F (CubedSphere part).
375    
376    checkpoint55a_post
377    o merged code to
378      * prescribe/read time-dependent open boundaries
379        (works in conjunction with exf, cal)
380      * sponge layer code for open boundaries
381      * each boundary N/S/E/W now has its own CPP option
382        (healthy for the adjoint)
383    
384    checkpoint55
385    o up-to-date adjoint of previous breaks
386      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
387      - global_ocean_ebm: adjoint still needs fix (TLM ok)
388      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
389      - carbon: * remove tr1-related adjoint verification
390                * add ptracer as control variable
391    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
392      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
393    
394    checkpoint54f_post
395    o in verification/carbin/ remove experiment related to
396      ALLOW_PASSIVE_TRACER (array tr1 etc)
397      code_ad/ input_ad/ results_ad
398    
399    o add two new packages
400      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
401        + subject to optimization (memory)
402      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
403        + subject to reordering (many GOTOs in the original code)
404        + so far opps is called for every (i,j) point, and then operates in
405          the vertical; one may want to reorder the scheme in order operate in
406          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
407          fields)
408    o overhaul of IO so that we now have flags for MDSIO and/or MNC
409      - all verification tests compile and run with linux_ia32_g77
410      - defaults are compatible with current input files--nothing
411        should change if you were not previously using MNC
412      - MNC output has been added in numerous places (eg. timeave)
413        but there are still a few writes not yet do-able with MNC
414        (this is in progress)
415      - flags now allow for either/or/both use of MDSIO and MNC and
416        documentation will soon follow
417      - numerous small formatting cleanups for ProTeX
418    o add version info (via BUILD_INFO.h) to MNC and stdout
419    
420    checkpoint54e_post
421    o add two new packages
422      - pp81 (Packanowski and Philander, 1981), Richardson number and
423        stratification dependent mixing
424      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
425      - these scheme operate in a similar manner as KPP (without ghat, of
426        course), however there is only one diffusivity that is used for both
427        temperature and salinity (and passive tracers)ç
428    o add offline package
429    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
430      provided by Stephanie Dutkiewicz
431    o genmake2: add ability to search for C compilers and cleanup test output
432      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
433    
434    checkpoint54d_post
435    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
436    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
437      leading to additional shift by 5 days each year of integration
438       (i.e. leading to considerable offset over the years)
439    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
440    o start with no AB and no initial filtering (staggerTimeStep):
441      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
442    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
443      (external loading & cpl import/export stay in forward_step.F)
444    o update coupling interface to work with new staggerTimeStep
445    o change MDSIO ptracers_pickup.
446    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
447    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
448    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
449    
450    checkpoint54c_post
451    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
452      this affects (truncation error) output.txt of test-exp:
453       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
454    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
455    o change Qnet to always be the net heat flux, (+upward).
456      affects (truncation error) output of natl_box exp.: updated
457    o define the max number of passive tracers in PTRACERS_SIZE.h
458    o start to test mnc routinely in exp0
459    o add sea-ice loading (sIceLoad) as a new forcing field.
460    
461    checkpoint54b_post
462    o add testreport "-j JOBS" option for parallel builds (tested and pretty
463       impressive on Altix and Opteron systems)
464    o diagnostics can now write NetCDF files through the mnc package
465    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
466    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
467    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
468      affects (truncation error) output of lab_sea & natl_box exp.: updated
469    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
470    
471    checkpoint54a_post
472    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
473    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
474    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
475    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
476      + internal_wave (shift in writing cg2d_ini_res)
477    checkpoint54a_pre
478    
479    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
480      - modified verification/lab_sea and natl_box_adjoint accordingly
481    
482    checkpoint54
483    checkpoint53g_post
484    o prepare splitting of thermodynamics: store convect.counter in common block
485    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
486      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
487    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
488    o new parameter "nShapS": allow to treat differently S from T (nShapT)
489    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
490    o restore adjointability
491    
492    checkpoint53f_post
493    o modifications that affect AIM experiment results (update output.txt):
494      - no advection of S at top interface Nr (pkg/generic_advdiff)
495      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
496    o AIM pkg:
497      - include stability function into surf.Flux derivative relative to Tsurf
498      - calculate clear-sky radiation & surface temp. change (for diagnostics)
499    
500    checkpoint53e_post
501    o merged cylindrical coord configuration
502    o added rotating_tank experiment
503    checkpoint53e_pre
504    
505    checkpoint53d_post
506    o faulks upgraded: re-generate output.txt that have changed:
507       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
508    o Added Bryan and Lewis, 1979, vertical diffusivity profile
509    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
510    o added Sadourny discretization of Coriolis
511      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
512      - re-enabled use of omega3 (useAbsVorticity)
513    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
514      vector-invariant equations
515      - note: does *NOT* yet use same variable visc. for no-slip BC's.
516    o recoded the lateral boundary conditions for non-hydrostatic w, this time
517      hopefully without new bugs
518      - still to do: biharmonic friction for non-hydrostatic w
519    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
520    o regenerated output for global_ocean_ebm (using -ieee)
521    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
522      of mom_common/
523      - simple re-arrangement of instructions within computing loop
524    checkpoint53d_pre
525    
526    checkpoint53c_post
527    o new version of coupler for AIM+thSIce and Ocean models
528     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
529     - land: change Evaporation of snow
530     - aim with thSIce: fix bug in snow-precip.
531    o changes to calc_gw.F
532     - bug fix for w^2 term near the bottom boundary
533     - (hopefully) improve the lateral slip boundary condtions for use with
534        partial/looped cells
535      - because the bug fix changes two verification experiments anyway (exp5
536        and plume on slope), change the lateral boundary condition from half slip
537        to the value of no_slip_sides
538    o ebm package wasnt quite up to the parallel task. Fixed that.
539    o Adjoint of EBM package + verification
540      * TLM OK
541      * ADM not sufficient accuracy yet (needs further testing)
542    
543    checkpoint53b_post
544    o Commiting new energy balance model to repository
545      * package is pkg/ebm
546      * verif. is verification/global_ocean_ebm
547      * references are in ebm_driver.F
548    C      * X. Wang, P. Stone and J. Marotzke, 1999:
549    C        Global thermohaline circulation. Part I:
550    C        Sensitivity to atmospheric moisture transport.
551    C        J. Climate 12(1), 71-82
552    C      * X. Wang, P. Stone and J. Marotzke, 1999:
553    C        Global thermohaline circulation. Part II:
554    C        Sensitivity with interactive transport.
555    C        J. Climate 12(1), 83-91
556    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
557    C        Destabilization of the thermohaline circulation
558    C        by atmospheric eddy transports.
559    C        J. Climate 7(12), 1870-1882
560    o Will need long integration testing.
561    checkpoint53b_pre
562    
563    o created pkg/mom_common in preparation for variable viscosity code
564    o renamed and split ini_mnc_io
565    o pkg/land: only liquid water can diffuse or run-off
566    o AIM using land: soil wetness availability account for snow
567    o added printMapIncludesZeros to EEPARMS namelist
568    
569    checkpoint53a_post
570    o restore TAMC compatiility for exf_constants.h
571      (no usage of _d in .h)
572    o Additional storing in KPP in an attempt to fix
573      TAMC problem with adjoint of KPP code.
574      (no success...)
575      Identical code works fine with TAF.
576    o Fixed verification/natl_box_adjoint experiments.
577      Initial conditions for Experiments 4 and 5 are now
578      set to "SEAICE_initialHEFF=0", which is more reasonable,
579      and hence gives results closer to that of Experiment 2.
580      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
581    
582    checkpoint53
583    o stable checkpoint with up to date adjoint
584      TLM tests only run for 1st grdchk at the moment. Its unclear if
585      this is a code problem or a problem with resetting code for g_
586      variables that is being autogenerated wrong.
587      Otherwise:
588       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
589       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
590         are both still in chaos following their security messes.
591    
592    checkpoint52n_post
593    o various build (mostly genmake2) changes including:
594      - ability to build/run more easily within Cygwin and MacOS X
595      - more complicated Makefiles with a stronger dependence on Gnu Make
596    o pkg/seaice modifications
597      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
598        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
599        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
600      - changed proxy for geostrophic velocity and updated
601        verification/lab_sea/results/* accordingly
602      - removed ADI dynamic solver from pkg/seaice
603      - replaced all occurrences of 1/CSTICE or 1/CSUICE
604        they caused a segmentation fault under certain circumstances
605      - removed unused field WATR
606    o bug fix in exf-package:
607      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
608         now reflect that.
609    o small fixes in the cal-package:
610      - set reference date to first of January for the 'model'-calendar
611      - failing of cal_CheckDate in cal_FullDate now actually results in a
612        warning
613    o small modifications in exf-package to increase flexibility:
614      - change climtempfreeze from a constant to a runtime parameter that
615        is specified in data.exf_clim (default = -1.9)
616      - introduce runtime parameter windstressmax (default = 2.0) that is
617        specified in data.exf
618    o fix in pkg/thsice:
619      - update Evap (Tsf changes) to be consistent with Latent heat flux
620      - maintain snow precipitation unchanged (even if Tsf >=0).
621     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
622    
623    checkpoint52m_post
624    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
625      this does not change any of the results, because myIter=0 in swfrac always
626      lead to jwtype=2 (the default anyway), but the call makes little sense
627      as a default
628    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
629    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
630      atmospheric model (AIM) to use it ; add a "slab ocean" component.
631    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
632    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
633    o extending useSingleCpuIO option to work with new exch2 I/O format
634      - old-style, missing-tile I/O is still accessible by defining CPP
635        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
636    o monitor package can write to NetCDF files and/or STDOUT
637    o fix re-definition bug in MNC_GRID_INIT_ALL()
638    o doc/api_reference added
639      - a framework for building an API Reference Manual using all
640        the "protex" comments embedded in the code
641      - see pkg/generic_advdiff, pkg/mnc for examples
642    o MNC:
643      - make myThid the last argument for all subroutines
644      - new default for the grid files: NO halos
645      - add useMNC and other run-time flags
646      - separate per-file-group handling of the unlimited dimension
647      - early initialization of MNC w/ flags read at the eeboot stage
648        and lookup tables set in initialize_fixed
649      - write all MNC output to a freshly-created directory
650    o thermodynamics sea-ice (thsice) is now tested with testreport.
651    o test exp. advect_cs: use the standard cs32 grid ; update output.
652    o Added functionality to grdchk:
653      pick global i,j,k position (or nearest wet) where to perform check.
654    
655    checkpoint52l_post
656    o new land formulation:
657      a) use ground enthalpy as prognostic variable to ensure exact
658         energy conservation.
659      b) account for water temperature and for latent heat of freezing
660         in all processes (rain, run-off, ground storage)
661      c) compute surface and ground temperature implicitly.
662    o aim_v23 modification for new land model:
663      a) Treat separately land / ocean / sea-ice surface fluxes
664         to allow implicit computation of land & sea-ice surface temp.
665      b) add snow precipitation.
666    checkpoint52l_pre
667    
668    o fix problem (when 1 tile is empty) in min/max monitor.
669    o fix bug in timeAve (u,vZetatave in common block)
670    o no restoring terms under ice for pkg/seaice
671    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
672    o bug fix for pkg/seaice pickups
673    o change MNC call locations and add coordinate attributes
674    o mask vorticity at the corner ; affects global_ocean.cs output
675    o fix ini_curvilinear_grid ; test CS experiments with mpi
676    o aim.5l_cs: modify sea-ice fraction input file ; update output
677    o exf: Adding simple range check routine for exf fields after read
678    
679    checkpoint52k_post
680    o removed top-level directory "diags"
681      - we migrated these functions to pkg/timeave a long time ago
682    o fixed bug introduced in pkg/monitor
683    o accuracy ctrlprec = 32 insuffient for gradient checks using
684      averaged fields (I/O via cost_averages)
685      -> use ctrl.h in active_file*.F to control I/O precision.
686    o paramter list of CALL ADTHE_MAIN_LOOP
687    o added initial do_the_model_io to ecco
688    o set all ...Freq to zero after cost_final
689      taveFreq, dumpFreq, pChkptFreq
690    o MAIN and ECCO differentiability restored
691    
692    checkpoint52j_post
693    o fix nchklev in tamc.h for global_ocean...
694    o Bringing flow and store directives up-to-date
695    o Really weird thing!
696      call do_the_model_io from the_main_loop with parameters
697      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
698      TAF places a faulty re-call of initialise_varia
699      after cost_final call which should not be there!
700    checkpoint52j_pre
701    
702    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
703      error messages
704    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
705    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
706      debug output
707    o modfied mdsio_writefield.F to handle non-global files under exch2
708    o update AIM Cubed-Sphere exp (aim.5l_cs):
709      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
710    o update AIM Equatorial Channel exp:
711      use standard aim_v23 pkg and change the SST fields to be more realistic.
712    o globalFile now works with exch2
713    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
714      mon_vort3.F to make exch2 friendly with >1 tile per cube face
715    o limit timeave output for hi-res integrations
716    
717    checkpoint52i_post
718    o removed CPP_EEOPTIONS.h from verification/*/code
719    o updated the tiling for global_ocean_pressure
720    checkpoint52i_pre
721    
722    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
723      the old pkg/aim).
724    
725    checkpoint52h_pre
726    o shortened offending lines in exch2_send_rx?.template
727    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
728    o genmake2: add build & execute test for NetCDF code
729    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
730      old grid files, moved CPP_EEMACROS.h to pkg/exch2
731    o added useSingleCPUIO flag to monitor.F and mon_out.F
732    o added temporary hack for sea-ice dynamics on the cube:
733      metric terms are ignored and it is assumed that
734      there is no sea-ice on cube faces 1, 2, 4, and 5.
735    
736    checkpoint52f_post
737    o added exch2 cube routines to pkg/exch2
738    o modified hs94.cs-32x32x5 to use it
739    o added new grid files to hs94.cs-32x32x5
740    checkpoint52f_pre
741    
742    checkpoint52e_post
743    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
744      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
745    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
746      to work with implicit vertical advection and AB ;
747    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
748    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
749     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
750    checkpoint52e_pre
751    
752    o fix bug in impldiff when Nr=1 or Nr=2.
753    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
754    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
755    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
756      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
757    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
758    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
759    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
760    
761    checkpoint52d_post
762    o re-tiled many expts to allow comparison in multi-processor mode
763      - updated output accordingly
764      - changed hs94.128x64x5 to use intial T from file rather than use the
765        random number generator
766    o add infrastructure in model routines for fizhi and gridalt packages
767    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
768    o changes to permit hi-res, cubed-sphere, configuration
769      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
770      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
771      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
772        of surface winds for the cube
773      (A verification experiment, based on global_ocean.cs32x15, but with
774       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
775       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
776       complete with example surface forcing files and matlab scripts to look
777       at the output and compare it with that of global_ocean.cs32x15.)
778    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
779       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
780       to conform to the common rule.
781    o check-in the first version of the coupler + interfaces for multi-components
782       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
783       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
784       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
785       - ocean and atmos. share the same horizontal grid (no interpolation).
786       - exchanges between component and coupler is done in forward_step
787    o new verification experiment, cpl_aim+ocn:
788       coupled ocean - AIM atmosphere on cs32 grid.
789    
790    checkpoint52d_pre
791    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
792    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
793    
794    checkpoint52c_post
795    o Fixing OPTIONS files for use of exf:
796      - ALLOW_ECCO not needed
797      - ECCO_CPPOPTIONS.h should not be included from
798        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
799        as has been the case in the past
800      - All cal/exf related options are currently set in
801        single header file. Should remain so until we
802        agree on a consistent new policy.
803    o Removed all CPP options for cal package.
804      cal has no more CPP options.
805    o modified STOREs in GAD_ADVECTION
806    o corrected key comp. for passkey
807    
808    checkpoint52b_post
809    o new version: "thsice" of thermodynamic sea-ice pkg:
810     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
811     - modify fluxes but do not change theta directly;
812     - light cleaning of bulk_force pkg (still needed with thsice).
813     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
814       + output_thsice.txt to test thsice & bulk_force pkgs.
815    o put back grid & coriolis monitor output.
816    checkpoint52b_pre
817    
818    o call "do_the_model_io" at the beginning (=> dump initial state)
819    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
820    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
821      (need info on NUMBER_OF_PTRACERS)
822    o missing PTRACERS headers in some routines
823    o default tamc.h in pkg/autodiff supposed to crash
824      to ensure proper customization
825    
826    checkpoint52a_post
827    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
828      - moved surfaceTendencyTice from pkg/seaice to main code
829      - subroutine FREEZE_SURFACE now limits only surface temperature
830        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
831        => new output.txt for global_ocean.cs32x15 & global_with_exf
832      - keep the old version of FREEZE for backward compatibility;
833        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
834      - corresponding modifs for TAF directives
835    o added surface flux output variables to TIMEAVE_STATVARS

842    o some bug fixes for #undef REAL4_IS_SLOW
843    
844    checkpoint52 = ecco_c52_e35
845    o after testing adjoints of checkpoint51u_post
846    
847    checkpoint51u_post
848    o this is the post-merge tag of the ecco-branch
849      (needs another clean checkout and re-testing)
850    o various natl_box_adjoint configs and results
851      but no input fields
852    o obcs adjoint not yet merged!
853    o adding ECCO global 1x1 and 2x2 degree configs
854    o updated/extended some store directives for seaice
855    o pkg/ecco now containes ecco-specific part of cost function
856    o top level routines the_main_loop, forward_step
857      supersede those in model/src/
858      previous input data.cost now in data.ecco
859      (new namelist ecco_cost_nml)
860    o in ctrl/ cleaned some cross-dependencies and updated CPP options
861    
862    checkpoint51t_post
863    o this is the pre-merge tag of the ecco-branch
864    
865    checkpoint51s_post
866    o cleanup: removed various obsolete #define-s
867    o pkg/grdchk
868      - renamed 'ph-grd 3' to 'grad-res'
869      - merged from ecco-branch
870        (remaining bug fixes for obcs gradient checks)
871      - additional high-precision output for testreport
872        (grep for 'precision_grdchk_result')
873    
874    checkpoint51r_post
875    o cleaned up or removed CPP_OPTIONS.h files
876    o updated results for some of the tests to reflect the new
877      optfiles (-ieee: -O0 instead of -O3)
878    
879    checkpoint51q_post
880    o cd_code:
881      - moved cd_scheme.F -> cd_code_scheme.F
882      - separate read_checkpoint from cd_code_ini_vars.F
883      - separated cd_code part from write_checkpoint
884      - updated AD_SOURCE, generated .flow
885      - added CD_CODE_VARS.h to the_main_loop
886      - Moving cd_code specific store dir.s to pkg/cd_code
887    o ctrl package totally restructured
888      - pack/unpack now optional and decoupled from
889        xx_/adxx_ I/O
890      - ctrl_pack/unpack cleaned

892      - confined inclusion of AD_CONFIG.h to where necessary.
893    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
894    
895    checkpoint51p_post
896    o create initial cd_code package
897      - WARNING: the initialization of fields within packages
898        is broken because INI_FIELDS (where READ_CHECKPOINT is
899        called) is called *before* PACKAGES_INIT_VARIABLES.
900        This seems to be backwards since
901        1) its important to initially zero the entire field including
902           the "halo" region
903        2) zeroing needs to be done *before* reading pickup info
904           and the pickup call might or might not happen in any
905           particular run
906      - this needs an overhaul for R2
907    o cleanup verification/*/code/GMREDI_OPTIONS.h
908    o cleanup testreport
909    
910    checkpoint51o_post
911    o bringing AD-related verif's up to date with genmake2

921        change rho -> rho-rhoConst
922      - replace call find_rho to find_rhonum
923    o initialisation of rFlx extended to full array (required by TAF)
924      and shifted to thermodynamics
925    o removed PTRACERS.h in ptracers routine
926    o added surfacetendencyPtr to S/R parameter list pracers_forcing

945         global_ocean.cs32x15, and global_with_exf)
946    o added surface flux output variables to TIMEAVE_STATVARS
947    
948    checkpoint51n_pre
949    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

1125      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1126      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1127        made the default because of faster convergence than ADI
1128    
1129    checkpoint50f_post
1130    o exf totally restructured

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