3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
7    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
8    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
9      this is based directly on what the model compute, so that the content of
10      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
11    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
12    o clean up build options files for SunOS, in particular
13      - remove -traditional from xmakedepend
14      - change -xarch=v9 to -xarch=native for f77
15      - restore use of make (not gmake)
16      - add CC=gcc if using g77
17    o changes per discussion of AM, JMC, & EH3 today:
18      - move redundant "grid" variables out of "state" -- in preparation of
19        creating proper CF-style coordinate variables and in recognition
20        that any/all grid variables can be easily copied (eg. w/NCO) from
21        the grid files into any of the other NetCDF files
22      - *always* output grid variables with MDSIO (this will eventually be
23        changed)
24      - output MNC grid file if useMNC is true
25    o every instance of _END_MASTER() has been found and replaced with
26      _END_MASTER( myThid ) in order to satisfy certain picky Sun
27      preprocessors
28    o re-arrange diagnostics pkg initialisation:
29     - allow each package to extend the available diagnostics list
30     - add some checking and fix small problems (multi-threaded, ...)
31     - new S/R diagnostics_fill (replace fill_diagnostics):
32       look through the short list of active diag. (instead of the long list)
33       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
34    
35    checkpoint57a_post
36    o this set of changes restores TAMC compatibility
37      tested for global_ocean.90x40x15 adjoint on trough
38      (what a pain)
39    
40    checkpoint57a_pre
41    o some modifs in tools/build_options for sunos
42    o call ctrl_pack for ctrl at end for optimcycle=0
43    
44    checkpoint57
45    o add horizontal bi-harmonic viscosity for vertical velocity
46      - new parameter viscA4W (defaults to viscA4)
47      - affects only non-hydrostatic code
48      - to be done: no-slip lateral boundary conditions
49    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
50    o implement Implicit Vertical advection for pTracers
51    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
52      (implemented also for implicit vertical diffusion & advection)
53    o OBCS: extend application of tracer open boundary conditions
54      to a strip beyond the boundary of width Olx/Oly
55    o add call monitor to TAF set of required calls (flow directives)
56      and include in natl_box_adjoint
57    o untangle a few ifdefs related to cost, ctrl, autodiff
58      untangel a few ALLOW_ECCO_OPTIMIZATION
59    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
60      (theta2, salt2 in ecco_cost_weights)
61    
62    checkpoint56c_post
63    o OBCS as control variables
64      - update ctrl_ad_diff.list, obcs_ad_diff.list
65      - remove balance of obcs controls from default
66      - fix index bug nobcs in ctrl_init
67      - fix dummy fields filen in ctrl_pack
68      - add dummy weights for obcs
69    o lsopt: comment out fort.94 output
70    o optim:
71      - remove unnecessary header files
72      - adjusted namelists
73      - add xerbla.F to Makefile
74    o exf:
75      - multiple modifications of exf_check_range
76      - unit change in exf_init_runoff from [m/year] to [m/s]
77    o mdsio:
78      - i/o-vector change debugLevel from debLevA to debLevB
79    
80    checkpoint56b_post
81    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
82      is called from DO_THE_MODEL_IO
83      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
84      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
85      - clean up PTRACERS_WRITE_TIMEAVE a little
86    o add another verification experiment that tests both the cfc-pkg and
87      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
88      reactive tendencies treated inline with regular timestepping
89    o testreport previously did a lousy job of comparing small numbers, so
90      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
91      implemented in the little c-progam tmp_cmpnum.c which is embedded in
92      testreport.
93    o ptracers_monitor: bug fix for MPI
94    
95    checkpoint56a_post
96    o GCHEM: finish reorganizating the package
97      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
98        (introduces another 3D-array for each passive tracer, but only if
99        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
100        gchemTendency is not needed because the timestep is done separately)
101      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
102      - GCHEM is now---more or less cleanly---separate from PTRACERS
103      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
104        so clear to me how that should be done in a general way.
105    o CFC: improve formatting of output in CFC_ATMOS
106    o PTRACERS:
107      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
108        that ALL experiments with ptracers enable can be checked. This makes
109        GCHEM_MONITOR obsolete.
110      - include a runtime parameter PTRACERS_monitorFreq that defaults to
111        monitorFreq
112      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
113    o add PTRACERS (PTR0[1-5]) to testreport output
114    o exf_check_range:
115      * default changed to .TRUE.
116      * will check values for niter0 if debLevA, every timestep if debLevB
117      * STOP in exf_check_range if 'out of range'
118      * range chosen generous to allow for potential extema
119      TBD: a version with stricter range
120           permitted range would be runtime parameters
121    o GMredi:
122      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
123      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
124      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
125    o GCHEM:
126      - move call to GCHEM_FORCING_SEP, so that it is now called before
127        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
128      - introduced a useGCHEM runtime flag and applied it everywhere.
129      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
130        this flag is now only visible within GCHEM-pkg routines.
131      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
132        be replaced by a 3D array that is computed before thermodynamics; for
133        this, the tracer ID iTracer had to be included into the parameter list
134        of ptracers_forcing
135      - set up forward_step to call gchem_forcing, that will replace
136        gchem_forcing_int in ptracers_forcing
137      - cleaning up
138    o small cleaning of exch2: remove files that are also in eesupp/src
139    
140    checkpoint56
141    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
142    o mnc: cleanup "full" files--fixes out-of-memory problem
143    o ECCO-GODAE
144      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
145      * fully merged and updated from SIO code
146        windstress sign change affects
147        - exf_inscal_[u/v]stress
148        - sign of xx_tau[u/v] adjustments
149        - signs in cost_scat
150      * ctrl_get_gen: avoid update of tau[u/v] for first few days
151      * natl_box_adjoint updated and compressed
152      * 2-level checkpoint switch added
153        (tested in EXP. 1 of natl_box_adjoint)
154      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
155    o SVD
156      * first complete, non-hacked version for SVD calculations
157      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
158        performed via direct access files admtlm_vector.it????
159        (via ctrl_[un]pack)
160      * optimcycle is used for ARPACK iteration counter
161        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
162      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
163        and add linear transforms where necessary
164      * controls are initial/final SST, SSS (can be extended; need to check
165        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
166    o mdsio: filename info to both stderr, stdout
167    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
168      from sign change
169    
170    checkpoint55j_post
171    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
172      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
173    o add consistent build directories and .cvsignore files to verification
174    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
175    o make all subroutines 30 or less characters in length for certain older
176      compilers to work (a thorough search only turns up two routines in
177      pkg/ptracers)
178    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
179      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
180    
181    checkpoint55i_post
182    o change arrays for total vertical diffusivity (2.D if explicit,
183      3.D if implicit) ; each ptracer uses its own background value.
184    o added mnc/NetCDF output capability to ocn_compon_interf
185      - added bits to verification/cpl_aim+ocn so that it can run on
186        ITRDA and other clusters without the mpirun "-wd" option
187    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
188      configuration
189    o give MNC the ability to create additional files rather than
190      exceeding a specified file size limit "MNC_MAX_FILESIZE"
191      - the default is just less than 2GB which is a practical limit
192        on many systems
193    o Compute the non-local term using either KPP vertical diffusivity (=default)
194       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
195    
196    checkpoint55h_post
197    o add verification test "vermix"
198    o remove all the *_ioinc flags and replace with the single global
199      outputTypesInclusive flag
200    o allow to set a vertical profile of vertical diffusivity for T & S
201    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
202    o useMNC moved from data.mnc to data.pkg
203    
204    checkpoint55g_post
205    o Renaming carbon AD experiments to comply with testreport conventions
206    o Updating adjoint of Held-Suarez hs94.1x64x5
207    o Fixing directives for non-ECCO forward_step, after ECCO directives
208      have been fixed to avoid recomp. of do_oceanic_phys
209      Works well for global_ocean.90x40x15,
210      but recomp. issue remains for carbon
211    o Updating adjoint output for natl_box_adjoint after
212      pkg/ecco has been modified (see taga c55d_post)
213    
214    checkpoint55f_post
215    o rename to timeave_init_fixed
216    
217    checkpoint55e_post
218    o some delicate re-shuffle of store directives to avoid one
219      extra call of do_oceanic_physics
220      affects ecco_the_main_loop.F, do_oceanic_physics.F
221      checkpoint_lev1_directives.h
222    o NB: this may break global_ocean adjoint temporarily,
223      but it is clear how to fix it. Will do later, need this now.
224    
225    checkpoint55d_post
226    o ECCO specific cost function terms (up-to-date with 1x1 runs)
227    o ecco_cost_weights is modified to 1x1 runs
228    o modifs to allow observations to be read in as
229      single file or yearly files
230    o enable to read exf forcing fields as either
231      single file or yearly files (flag useExfYearlyFields)
232    checkpoint55d_pre
233    
234    o switch between 2-level and 3-level checkpointing
235    o add ability of MNC to write local and "partial" (eg. 2D slices where
236      the full 3D field is never actually stored) arrays to NetCDF files
237      with the correct (that is, the complete multi-dimensional) set of
238      array indicies
239      - used in mom_vecinv() to write the diagFreq output
240      - tested (demonstrated) in verification/aim.5l_cs
241    o further mnc-ification
242      - add verification/lab_sea to the list with mnc setups
243      - fix undefined mnc v-names in cd_code
244      - add kpp to mnc output (both snapshot and timeave)
245    o non-hydrostatic code
246      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
247        in calc_gw.F
248      - defaults to viscAh
249      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
250        friction or Leith) in non-hydrostatic mode, as long as there is
251        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
252    o pkg/cost
253      extend simple cost functions to treat time mean quantities
254      (T,U,V) via cost_accumulate_state from cost_tile
255    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
256        be 2 times larger than the minimum size the advection scheme requires.
257        now get a perfect conservation of salt in advect_cs test-exp (updated)
258    o GGL90 (Gaspar's TKE mixed layer)
259      - add horizontal diffusion of TKE, requires exchanges in
260        do_fields_blocking_exchanges, horizontal diffusivity is zero by
261        default. In OPA there is no horizontal diffusion of TKE but the
262        mixing coefficients are computed from a horizontal average of TKE of
263        6 points or so. I think that diffusion has a little more physical
264        justification.
265      - clean up ggl90_calc in the hope of reducing memory usage (this hope
266        was in vain)
267      - mask tke-variable in ggl90_init
268    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
269    o fix biharmonic diffusion on CS-grid.
270    o more obcs stuff
271      - added obcs_external_fields_load as an alternative to the EXF-pkg option
272        for reading boundary values. This routine is called from
273        obcs_prescribe_read
274      - updated obcs_check
275      - changed sponge layer relaxation parameter units for days to seconds
276      - turned off sponge layer by default
277      - changed argument list of OBCS_CALC to myTime+deltaTclock
278      - fixed about 35 bugs in obcs_external_fields_load
279    
280    checkpoint55c_post
281    o obcs stuff
282      - new runtime flags useOBCSprescribe, useOBCSbalance
283      - re-arranged obcs_calc
284      - moved exf_getobcs to obcs_prescibe_read
285        obcs_prescibe_read is called after ORLANSKI stuff
286        and independent of it (executable can contain all).
287      - updated obcs_check
288      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
289        These may be necessary only if tangential velocities are
290        prescribed at OB, not sure, needs testing.
291    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
292      which simplifies the calls and passes the ifc check-bounds test
293    
294    checkpoint55b_post
295    o add a 2D scalar, Z location, exchange_2 routine.
296    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
297      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
298      affects advect_cs results (for the wrong reason): update output.txt
299    o use a more standard discretization for biharmonic viscosity ;
300     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
301      affects results of dome set-up: update output.txt
302    o fix gad_advection.F (CubedSphere part), back to version 1.23
303    o fix bug in mom_vi_del2uv.F (CubedSphere part).
304    
305    checkpoint55a_post
306    o merged code to
307      * prescribe/read time-dependent open boundaries
308        (works in conjunction with exf, cal)
309      * sponge layer code for open boundaries
310      * each boundary N/S/E/W now has its own CPP option
311        (healthy for the adjoint)
312    
313    checkpoint55
314    o up-to-date adjoint of previous breaks
315      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
316      - global_ocean_ebm: adjoint still needs fix (TLM ok)
317      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
318      - carbon: * remove tr1-related adjoint verification
319                * add ptracer as control variable
320    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
321      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
322    
323    checkpoint54f_post
324    o in verification/carbin/ remove experiment related to
325      ALLOW_PASSIVE_TRACER (array tr1 etc)
326      code_ad/ input_ad/ results_ad
327    
328    o add two new packages
329      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
330        + subject to optimization (memory)
331      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
332        + subject to reordering (many GOTOs in the original code)
333        + so far opps is called for every (i,j) point, and then operates in
334          the vertical; one may want to reorder the scheme in order operate in
335          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
336          fields)
337    o overhaul of IO so that we now have flags for MDSIO and/or MNC
338      - all verification tests compile and run with linux_ia32_g77
339      - defaults are compatible with current input files--nothing
340        should change if you were not previously using MNC
341      - MNC output has been added in numerous places (eg. timeave)
342        but there are still a few writes not yet do-able with MNC
343        (this is in progress)
344      - flags now allow for either/or/both use of MDSIO and MNC and
345        documentation will soon follow
346      - numerous small formatting cleanups for ProTeX
347    o add version info (via BUILD_INFO.h) to MNC and stdout
348    
349    checkpoint54e_post
350    o add two new packages
351      - pp81 (Packanowski and Philander, 1981), Richardson number and
352        stratification dependent mixing
353      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
354      - these scheme operate in a similar manner as KPP (without ghat, of
355        course), however there is only one diffusivity that is used for both
356        temperature and salinity (and passive tracers)ç
357    o add offline package
358    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
359      provided by Stephanie Dutkiewicz
360    o genmake2: add ability to search for C compilers and cleanup test output
361      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
362    
363    checkpoint54d_post
364    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
365    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
366      leading to additional shift by 5 days each year of integration
367       (i.e. leading to considerable offset over the years)
368    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
369    o start with no AB and no initial filtering (staggerTimeStep):
370      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
371    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
372      (external loading & cpl import/export stay in forward_step.F)
373    o update coupling interface to work with new staggerTimeStep
374    o change MDSIO ptracers_pickup.
375    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
376    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
377    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
378    
379    checkpoint54c_post
380    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
381      this affects (truncation error) output.txt of test-exp:
382       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
383    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
384    o change Qnet to always be the net heat flux, (+upward).
385      affects (truncation error) output of natl_box exp.: updated
386    o define the max number of passive tracers in PTRACERS_SIZE.h
387    o start to test mnc routinely in exp0
388    o add sea-ice loading (sIceLoad) as a new forcing field.
389    
390    checkpoint54b_post
391    o add testreport "-j JOBS" option for parallel builds (tested and pretty
392       impressive on Altix and Opteron systems)
393    o diagnostics can now write NetCDF files through the mnc package
394    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
395    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
396    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
397      affects (truncation error) output of lab_sea & natl_box exp.: updated
398    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
399    
400    checkpoint54a_post
401    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
402    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
403    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
404    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
405      + internal_wave (shift in writing cg2d_ini_res)
406    checkpoint54a_pre
407    
408    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
409      - modified verification/lab_sea and natl_box_adjoint accordingly
410    
411    checkpoint54
412    checkpoint53g_post
413    o prepare splitting of thermodynamics: store convect.counter in common block
414    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
415      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
416    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
417    o new parameter "nShapS": allow to treat differently S from T (nShapT)
418    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
419    o restore adjointability
420    
421    checkpoint53f_post
422    o modifications that affect AIM experiment results (update output.txt):
423      - no advection of S at top interface Nr (pkg/generic_advdiff)
424      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
425    o AIM pkg:
426      - include stability function into surf.Flux derivative relative to Tsurf
427      - calculate clear-sky radiation & surface temp. change (for diagnostics)
428    
429    checkpoint53e_post
430    o merged cylindrical coord configuration
431    o added rotating_tank experiment
432    checkpoint53e_pre
433    
434    checkpoint53d_post
435    o faulks upgraded: re-generate output.txt that have changed:
436       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
437    o Added Bryan and Lewis, 1979, vertical diffusivity profile
438    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
439    o added Sadourny discretization of Coriolis
440      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
441      - re-enabled use of omega3 (useAbsVorticity)
442    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
443      vector-invariant equations
444      - note: does *NOT* yet use same variable visc. for no-slip BC's.
445    o recoded the lateral boundary conditions for non-hydrostatic w, this time
446      hopefully without new bugs
447      - still to do: biharmonic friction for non-hydrostatic w
448    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
449    o regenerated output for global_ocean_ebm (using -ieee)
450    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
451      of mom_common/
452      - simple re-arrangement of instructions within computing loop
453    checkpoint53d_pre
454    
455    checkpoint53c_post
456    o new version of coupler for AIM+thSIce and Ocean models
457     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
458     - land: change Evaporation of snow
459     - aim with thSIce: fix bug in snow-precip.
460    o changes to calc_gw.F
461     - bug fix for w^2 term near the bottom boundary
462     - (hopefully) improve the lateral slip boundary condtions for use with
463        partial/looped cells
464      - because the bug fix changes two verification experiments anyway (exp5
465        and plume on slope), change the lateral boundary condition from half slip
466        to the value of no_slip_sides
467    o ebm package wasnt quite up to the parallel task. Fixed that.
468    o Adjoint of EBM package + verification
469      * TLM OK
470      * ADM not sufficient accuracy yet (needs further testing)
471    
472    checkpoint53b_post
473    o Commiting new energy balance model to repository
474      * package is pkg/ebm
475      * verif. is verification/global_ocean_ebm
476      * references are in ebm_driver.F
477    C      * X. Wang, P. Stone and J. Marotzke, 1999:
478    C        Global thermohaline circulation. Part I:
479    C        Sensitivity to atmospheric moisture transport.

481    C      * X. Wang, P. Stone and J. Marotzke, 1999:
482    C        Global thermohaline circulation. Part II:
483    C        Sensitivity with interactive transport.

485    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
486    C        Destabilization of the thermohaline circulation
487    C        by atmospheric eddy transports.
488    C        J. Climate 7(12), 1870-1882
489    o Will need long integration testing.
490    checkpoint53b_pre
491    
492    o created pkg/mom_common in preparation for variable viscosity code
493    o renamed and split ini_mnc_io
494    o pkg/land: only liquid water can diffuse or run-off
495    o AIM using land: soil wetness availability account for snow
496    o added printMapIncludesZeros to EEPARMS namelist
497    
498    checkpoint53a_post
499    o restore TAMC compatiility for exf_constants.h
500      (no usage of _d in .h)
501    o Additional storing in KPP in an attempt to fix
502      TAMC problem with adjoint of KPP code.
503      (no success...)
504      Identical code works fine with TAF.
505    o Fixed verification/natl_box_adjoint experiments.
506      Initial conditions for Experiments 4 and 5 are now
507      set to "SEAICE_initialHEFF=0", which is more reasonable,
508      and hence gives results closer to that of Experiment 2.
509      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
510    
511    checkpoint53
512    o stable checkpoint with up to date adjoint
513      TLM tests only run for 1st grdchk at the moment. Its unclear if
514      this is a code problem or a problem with resetting code for g_
515      variables that is being autogenerated wrong.
516      Otherwise:
517       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
518       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
519         are both still in chaos following their security messes.
520    
521    checkpoint52n_post
522    o various build (mostly genmake2) changes including:
523      - ability to build/run more easily within Cygwin and MacOS X
524      - more complicated Makefiles with a stronger dependence on Gnu Make
525    o pkg/seaice modifications
526      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
527        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
528        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
529      - changed proxy for geostrophic velocity and updated
530        verification/lab_sea/results/* accordingly
531      - removed ADI dynamic solver from pkg/seaice
532      - replaced all occurrences of 1/CSTICE or 1/CSUICE
533        they caused a segmentation fault under certain circumstances
534      - removed unused field WATR
535    o bug fix in exf-package:
536      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
537         now reflect that.
538    o small fixes in the cal-package:
539      - set reference date to first of January for the 'model'-calendar
540      - failing of cal_CheckDate in cal_FullDate now actually results in a
541        warning
542    o small modifications in exf-package to increase flexibility:
543      - change climtempfreeze from a constant to a runtime parameter that
544        is specified in data.exf_clim (default = -1.9)
545      - introduce runtime parameter windstressmax (default = 2.0) that is
546        specified in data.exf
547    o fix in pkg/thsice:
548      - update Evap (Tsf changes) to be consistent with Latent heat flux
549      - maintain snow precipitation unchanged (even if Tsf >=0).
550     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
551    
552    checkpoint52m_post
553    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
554      this does not change any of the results, because myIter=0 in swfrac always
555      lead to jwtype=2 (the default anyway), but the call makes little sense
556      as a default
557    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
558    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
559      atmospheric model (AIM) to use it ; add a "slab ocean" component.
560    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
561    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
562    o extending useSingleCpuIO option to work with new exch2 I/O format
563      - old-style, missing-tile I/O is still accessible by defining CPP
564        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
565    o monitor package can write to NetCDF files and/or STDOUT
566    o fix re-definition bug in MNC_GRID_INIT_ALL()
567    o doc/api_reference added
568      - a framework for building an API Reference Manual using all
569        the "protex" comments embedded in the code
570      - see pkg/generic_advdiff, pkg/mnc for examples
571    o MNC:
572      - make myThid the last argument for all subroutines
573      - new default for the grid files: NO halos
574      - add useMNC and other run-time flags
575      - separate per-file-group handling of the unlimited dimension
576      - early initialization of MNC w/ flags read at the eeboot stage
577        and lookup tables set in initialize_fixed
578      - write all MNC output to a freshly-created directory
579    o thermodynamics sea-ice (thsice) is now tested with testreport.
580    o test exp. advect_cs: use the standard cs32 grid ; update output.
581    o Added functionality to grdchk:
582      pick global i,j,k position (or nearest wet) where to perform check.
583    
584    checkpoint52l_post
585    o new land formulation:
586      a) use ground enthalpy as prognostic variable to ensure exact
587         energy conservation.
588      b) account for water temperature and for latent heat of freezing
589         in all processes (rain, run-off, ground storage)
590      c) compute surface and ground temperature implicitly.
591    o aim_v23 modification for new land model:
592      a) Treat separately land / ocean / sea-ice surface fluxes
593         to allow implicit computation of land & sea-ice surface temp.
594      b) add snow precipitation.
595    checkpoint52l_pre
596    
597    o fix problem (when 1 tile is empty) in min/max monitor.
598    o fix bug in timeAve (u,vZetatave in common block)
599    o no restoring terms under ice for pkg/seaice
600    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
601    o bug fix for pkg/seaice pickups
602    o change MNC call locations and add coordinate attributes
603    o mask vorticity at the corner ; affects global_ocean.cs output
604    o fix ini_curvilinear_grid ; test CS experiments with mpi
605    o aim.5l_cs: modify sea-ice fraction input file ; update output
606    o exf: Adding simple range check routine for exf fields after read
607    
608    checkpoint52k_post
609    o removed top-level directory "diags"
610      - we migrated these functions to pkg/timeave a long time ago
611    o fixed bug introduced in pkg/monitor
612    o accuracy ctrlprec = 32 insuffient for gradient checks using
613      averaged fields (I/O via cost_averages)
614      -> use ctrl.h in active_file*.F to control I/O precision.
615    o paramter list of CALL ADTHE_MAIN_LOOP
616    o added initial do_the_model_io to ecco
617    o set all ...Freq to zero after cost_final
618      taveFreq, dumpFreq, pChkptFreq
619    o MAIN and ECCO differentiability restored
620    
621    checkpoint52j_post
622    o fix nchklev in tamc.h for global_ocean...
623    o Bringing flow and store directives up-to-date
624    o Really weird thing!
625      call do_the_model_io from the_main_loop with parameters
626      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
627      TAF places a faulty re-call of initialise_varia
628      after cost_final call which should not be there!
629    checkpoint52j_pre
630    
631    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
632      error messages
633    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
634    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
635      debug output
636    o modfied mdsio_writefield.F to handle non-global files under exch2
637    o update AIM Cubed-Sphere exp (aim.5l_cs):
638      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
639    o update AIM Equatorial Channel exp:
640      use standard aim_v23 pkg and change the SST fields to be more realistic.
641    o globalFile now works with exch2
642    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
643      mon_vort3.F to make exch2 friendly with >1 tile per cube face
644    o limit timeave output for hi-res integrations
645    
646    checkpoint52i_post
647    o removed CPP_EEOPTIONS.h from verification/*/code
648    o updated the tiling for global_ocean_pressure
649    checkpoint52i_pre
650    
651    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
652      the old pkg/aim).
653    
654    checkpoint52h_pre
655    o shortened offending lines in exch2_send_rx?.template
656    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
657    o genmake2: add build & execute test for NetCDF code
658    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
659      old grid files, moved CPP_EEMACROS.h to pkg/exch2
660    o added useSingleCPUIO flag to monitor.F and mon_out.F
661    o added temporary hack for sea-ice dynamics on the cube:
662      metric terms are ignored and it is assumed that
663      there is no sea-ice on cube faces 1, 2, 4, and 5.
664    
665    checkpoint52f_post
666    o added exch2 cube routines to pkg/exch2
667    o modified hs94.cs-32x32x5 to use it
668    o added new grid files to hs94.cs-32x32x5
669    checkpoint52f_pre
670    
671    checkpoint52e_post
672    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
673      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
674    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
675      to work with implicit vertical advection and AB ;
676    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
677    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
678     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
679    checkpoint52e_pre
680    
681    o fix bug in impldiff when Nr=1 or Nr=2.
682    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
683    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
684    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
685      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
686    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
687    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
688    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
689    
690    checkpoint52d_post
691    o re-tiled many expts to allow comparison in multi-processor mode
692      - updated output accordingly
693      - changed hs94.128x64x5 to use intial T from file rather than use the
694        random number generator
695    o add infrastructure in model routines for fizhi and gridalt packages
696    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
697    o changes to permit hi-res, cubed-sphere, configuration
698      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
699      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
700      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
701        of surface winds for the cube
702      (A verification experiment, based on global_ocean.cs32x15, but with
703       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
704       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
705       complete with example surface forcing files and matlab scripts to look
706       at the output and compare it with that of global_ocean.cs32x15.)
707    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
708       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
709       to conform to the common rule.
710    o check-in the first version of the coupler + interfaces for multi-components
711       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
712       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
713       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
714       - ocean and atmos. share the same horizontal grid (no interpolation).
715       - exchanges between component and coupler is done in forward_step
716    o new verification experiment, cpl_aim+ocn:
717       coupled ocean - AIM atmosphere on cs32 grid.
718    
719    checkpoint52d_pre
720    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
721    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
722    
723    checkpoint52c_post
724    o Fixing OPTIONS files for use of exf:
725      - ALLOW_ECCO not needed
726      - ECCO_CPPOPTIONS.h should not be included from
727        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
728        as has been the case in the past
729      - All cal/exf related options are currently set in
730        single header file. Should remain so until we
731        agree on a consistent new policy.
732    o Removed all CPP options for cal package.
733      cal has no more CPP options.
734    o modified STOREs in GAD_ADVECTION
735    o corrected key comp. for passkey
736    
737    checkpoint52b_post
738    o new version: "thsice" of thermodynamic sea-ice pkg:
739     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
740     - modify fluxes but do not change theta directly;
741     - light cleaning of bulk_force pkg (still needed with thsice).
742     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
743       + output_thsice.txt to test thsice & bulk_force pkgs.
744    o put back grid & coriolis monitor output.
745    checkpoint52b_pre
746    
747    o call "do_the_model_io" at the beginning (=> dump initial state)
748    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
749    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
750      (need info on NUMBER_OF_PTRACERS)
751    o missing PTRACERS headers in some routines
752    o default tamc.h in pkg/autodiff supposed to crash
753      to ensure proper customization
754    
755    checkpoint52a_post
756    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
757      - moved surfaceTendencyTice from pkg/seaice to main code
758      - subroutine FREEZE_SURFACE now limits only surface temperature
759        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
760        => new output.txt for global_ocean.cs32x15 & global_with_exf
761      - keep the old version of FREEZE for backward compatibility;
762        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
763      - corresponding modifs for TAF directives
764    o added surface flux output variables to TIMEAVE_STATVARS
765    o time-averaged output for pkg/ptracers
766    o fix problem with ECCO-related divided adjoint
767      snapshot file was missing some ad-variables,
768      but no warning issued by TAF
769    
770    checkpoint52a_pre
771    o some bug fixes for #undef REAL4_IS_SLOW
772    
773    checkpoint52 = ecco_c52_e35
774    o after testing adjoints of checkpoint51u_post
775    
776    checkpoint51u_post
777    o this is the post-merge tag of the ecco-branch
778      (needs another clean checkout and re-testing)
779    o various natl_box_adjoint configs and results
780      but no input fields

787      previous input data.cost now in data.ecco
788      (new namelist ecco_cost_nml)
789    o in ctrl/ cleaned some cross-dependencies and updated CPP options
790    
791    checkpoint51t_post
792    o this is the pre-merge tag of the ecco-branch
793    
794    checkpoint51s_post
795    o cleanup: removed various obsolete #define-s
796    o pkg/grdchk
797      - renamed 'ph-grd 3' to 'grad-res'
798      - merged from ecco-branch
799        (remaining bug fixes for obcs gradient checks)
800      - additional high-precision output for testreport
801        (grep for 'precision_grdchk_result')
802    
803    checkpoint51r_post
804    o cleaned up or removed CPP_OPTIONS.h files
805    o updated results for some of the tests to reflect the new
806      optfiles (-ieee: -O0 instead of -O3)
807    
808    checkpoint51q_post
809    o cd_code:
810      - moved cd_scheme.F -> cd_code_scheme.F
811      - separate read_checkpoint from cd_code_ini_vars.F

822    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
823    
824    checkpoint51p_post
825    o create initial cd_code package
826      - WARNING: the initialization of fields within packages
827        is broken because INI_FIELDS (where READ_CHECKPOINT is
828        called) is called *before* PACKAGES_INIT_VARIABLES.
829        This seems to be backwards since
830        1) its important to initially zero the entire field including
831           the "halo" region
832        2) zeroing needs to be done *before* reading pickup info
833           and the pickup call might or might not happen in any
834           particular run
835      - this needs an overhaul for R2
836    o cleanup verification/*/code/GMREDI_OPTIONS.h

874         global_ocean.cs32x15, and global_with_exf)
875    o added surface flux output variables to TIMEAVE_STATVARS
876    
877    checkpoint51n_pre
878    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
