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

462    C      * X. Wang, P. Stone and J. Marotzke, 1999:
463    C        Global thermohaline circulation. Part II:

466    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
467    C        Destabilization of the thermohaline circulation
468    C        by atmospheric eddy transports.
469    C        J. Climate 7(12), 1870-1882
470    o Will need long integration testing.
471    checkpoint53b_pre
472    
473    o created pkg/mom_common in preparation for variable viscosity code
474    o renamed and split ini_mnc_io
475    o pkg/land: only liquid water can diffuse or run-off
476    o AIM using land: soil wetness availability account for snow
477    o added printMapIncludesZeros to EEPARMS namelist
478    
479    checkpoint53a_post
480    o restore TAMC compatiility for exf_constants.h
481      (no usage of _d in .h)
482    o Additional storing in KPP in an attempt to fix
483      TAMC problem with adjoint of KPP code.
484      (no success...)
485      Identical code works fine with TAF.
486    o Fixed verification/natl_box_adjoint experiments.
487      Initial conditions for Experiments 4 and 5 are now
488      set to "SEAICE_initialHEFF=0", which is more reasonable,
489      and hence gives results closer to that of Experiment 2.
490      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
491    
492    checkpoint53
493    o stable checkpoint with up to date adjoint
494      TLM tests only run for 1st grdchk at the moment. Its unclear if
495      this is a code problem or a problem with resetting code for g_
496      variables that is being autogenerated wrong.
497      Otherwise:
498       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
499       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
500         are both still in chaos following their security messes.
501    
502    checkpoint52n_post
503    o various build (mostly genmake2) changes including:
504      - ability to build/run more easily within Cygwin and MacOS X
505      - more complicated Makefiles with a stronger dependence on Gnu Make
506    o pkg/seaice modifications
507      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
508        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
509        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
510      - changed proxy for geostrophic velocity and updated
511        verification/lab_sea/results/* accordingly
512      - removed ADI dynamic solver from pkg/seaice
513      - replaced all occurrences of 1/CSTICE or 1/CSUICE
514        they caused a segmentation fault under certain circumstances
515      - removed unused field WATR
516    o bug fix in exf-package:
517      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
518         now reflect that.
519    o small fixes in the cal-package:
520      - set reference date to first of January for the 'model'-calendar
521      - failing of cal_CheckDate in cal_FullDate now actually results in a
522        warning
523    o small modifications in exf-package to increase flexibility:
524      - change climtempfreeze from a constant to a runtime parameter that
525        is specified in data.exf_clim (default = -1.9)
526      - introduce runtime parameter windstressmax (default = 2.0) that is
527        specified in data.exf
528    o fix in pkg/thsice:
529      - update Evap (Tsf changes) to be consistent with Latent heat flux
530      - maintain snow precipitation unchanged (even if Tsf >=0).
531     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
532    
533    checkpoint52m_post
534    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
535      this does not change any of the results, because myIter=0 in swfrac always
536      lead to jwtype=2 (the default anyway), but the call makes little sense
537      as a default
538    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
539    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
540      atmospheric model (AIM) to use it ; add a "slab ocean" component.
541    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
542    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
543    o extending useSingleCpuIO option to work with new exch2 I/O format
544      - old-style, missing-tile I/O is still accessible by defining CPP
545        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
546    o monitor package can write to NetCDF files and/or STDOUT
547    o fix re-definition bug in MNC_GRID_INIT_ALL()
548    o doc/api_reference added
549      - a framework for building an API Reference Manual using all
550        the "protex" comments embedded in the code
551      - see pkg/generic_advdiff, pkg/mnc for examples
552    o MNC:
553      - make myThid the last argument for all subroutines
554      - new default for the grid files: NO halos
555      - add useMNC and other run-time flags
556      - separate per-file-group handling of the unlimited dimension
557      - early initialization of MNC w/ flags read at the eeboot stage
558        and lookup tables set in initialize_fixed
559      - write all MNC output to a freshly-created directory
560    o thermodynamics sea-ice (thsice) is now tested with testreport.
561    o test exp. advect_cs: use the standard cs32 grid ; update output.
562    o Added functionality to grdchk:
563      pick global i,j,k position (or nearest wet) where to perform check.
564    
565    checkpoint52l_post
566    o new land formulation:
567      a) use ground enthalpy as prognostic variable to ensure exact
568         energy conservation.
569      b) account for water temperature and for latent heat of freezing
570         in all processes (rain, run-off, ground storage)
571      c) compute surface and ground temperature implicitly.
572    o aim_v23 modification for new land model:
573      a) Treat separately land / ocean / sea-ice surface fluxes
574         to allow implicit computation of land & sea-ice surface temp.
575      b) add snow precipitation.
576    checkpoint52l_pre
577    
578    o fix problem (when 1 tile is empty) in min/max monitor.
579    o fix bug in timeAve (u,vZetatave in common block)
580    o no restoring terms under ice for pkg/seaice
581    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
582    o bug fix for pkg/seaice pickups
583    o change MNC call locations and add coordinate attributes
584    o mask vorticity at the corner ; affects global_ocean.cs output
585    o fix ini_curvilinear_grid ; test CS experiments with mpi
586    o aim.5l_cs: modify sea-ice fraction input file ; update output
587    o exf: Adding simple range check routine for exf fields after read
588    
589    checkpoint52k_post
590    o removed top-level directory "diags"
591      - we migrated these functions to pkg/timeave a long time ago
592    o fixed bug introduced in pkg/monitor
593    o accuracy ctrlprec = 32 insuffient for gradient checks using
594      averaged fields (I/O via cost_averages)
595      -> use ctrl.h in active_file*.F to control I/O precision.
596    o paramter list of CALL ADTHE_MAIN_LOOP
597    o added initial do_the_model_io to ecco
598    o set all ...Freq to zero after cost_final
599      taveFreq, dumpFreq, pChkptFreq
600    o MAIN and ECCO differentiability restored
601    
602    checkpoint52j_post
603    o fix nchklev in tamc.h for global_ocean...
604    o Bringing flow and store directives up-to-date
605    o Really weird thing!
606      call do_the_model_io from the_main_loop with parameters
607      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
608      TAF places a faulty re-call of initialise_varia
609      after cost_final call which should not be there!
610    checkpoint52j_pre
611    
612    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
613      error messages
614    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
615    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
616      debug output
617    o modfied mdsio_writefield.F to handle non-global files under exch2
618    o update AIM Cubed-Sphere exp (aim.5l_cs):
619      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
620    o update AIM Equatorial Channel exp:
621      use standard aim_v23 pkg and change the SST fields to be more realistic.
622    o globalFile now works with exch2
623    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
624      mon_vort3.F to make exch2 friendly with >1 tile per cube face
625    o limit timeave output for hi-res integrations
626    
627    checkpoint52i_post
628    o removed CPP_EEOPTIONS.h from verification/*/code
629    o updated the tiling for global_ocean_pressure
630    checkpoint52i_pre
631    
632    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
633      the old pkg/aim).
634    
635    checkpoint52h_pre
636    o shortened offending lines in exch2_send_rx?.template
637    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
638    o genmake2: add build & execute test for NetCDF code
639    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
640      old grid files, moved CPP_EEMACROS.h to pkg/exch2
641    o added useSingleCPUIO flag to monitor.F and mon_out.F
642    o added temporary hack for sea-ice dynamics on the cube:
643      metric terms are ignored and it is assumed that
644      there is no sea-ice on cube faces 1, 2, 4, and 5.
645    
646    checkpoint52f_post
647    o added exch2 cube routines to pkg/exch2
648    o modified hs94.cs-32x32x5 to use it
649    o added new grid files to hs94.cs-32x32x5
650    checkpoint52f_pre
651    
652    checkpoint52e_post
653    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
654      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
655    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
656      to work with implicit vertical advection and AB ;
657    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
658    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
659     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
660    checkpoint52e_pre
661    
662    o fix bug in impldiff when Nr=1 or Nr=2.
663    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
664    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
665    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
666      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
667    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
668    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
669    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
670    
671    checkpoint52d_post
672    o re-tiled many expts to allow comparison in multi-processor mode
673      - updated output accordingly
674      - changed hs94.128x64x5 to use intial T from file rather than use the
675        random number generator
676    o add infrastructure in model routines for fizhi and gridalt packages
677    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
678    o changes to permit hi-res, cubed-sphere, configuration
679      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
680      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
681      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
682        of surface winds for the cube
683      (A verification experiment, based on global_ocean.cs32x15, but with
684       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
685       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
686       complete with example surface forcing files and matlab scripts to look
687       at the output and compare it with that of global_ocean.cs32x15.)
688    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
689       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
690       to conform to the common rule.
691    o check-in the first version of the coupler + interfaces for multi-components
692       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
693       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
694       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
695       - ocean and atmos. share the same horizontal grid (no interpolation).
696       - exchanges between component and coupler is done in forward_step
697    o new verification experiment, cpl_aim+ocn:
698       coupled ocean - AIM atmosphere on cs32 grid.
699    
700    checkpoint52d_pre
701    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
702    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
703    
704    checkpoint52c_post
705    o Fixing OPTIONS files for use of exf:
706      - ALLOW_ECCO not needed
707      - ECCO_CPPOPTIONS.h should not be included from
708        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
709        as has been the case in the past
710      - All cal/exf related options are currently set in
711        single header file. Should remain so until we
712        agree on a consistent new policy.
713    o Removed all CPP options for cal package.
714      cal has no more CPP options.
715    o modified STOREs in GAD_ADVECTION
716    o corrected key comp. for passkey
717    
718    checkpoint52b_post
719    o new version: "thsice" of thermodynamic sea-ice pkg:
720     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
721     - modify fluxes but do not change theta directly;
722     - light cleaning of bulk_force pkg (still needed with thsice).
723     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
724       + output_thsice.txt to test thsice & bulk_force pkgs.
725    o put back grid & coriolis monitor output.
726    checkpoint52b_pre
727    
728    o call "do_the_model_io" at the beginning (=> dump initial state)
729    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
730    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
731      (need info on NUMBER_OF_PTRACERS)
732    o missing PTRACERS headers in some routines
733    o default tamc.h in pkg/autodiff supposed to crash
734      to ensure proper customization
735    
736    checkpoint52a_post
737    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
738      - moved surfaceTendencyTice from pkg/seaice to main code
739      - subroutine FREEZE_SURFACE now limits only surface temperature
740        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
741        => new output.txt for global_ocean.cs32x15 & global_with_exf
742      - keep the old version of FREEZE for backward compatibility;
743        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
744      - corresponding modifs for TAF directives
745    o added surface flux output variables to TIMEAVE_STATVARS
746    o time-averaged output for pkg/ptracers
747    o fix problem with ECCO-related divided adjoint
748      snapshot file was missing some ad-variables,
749      but no warning issued by TAF
750    
751    checkpoint52a_pre
752    o some bug fixes for #undef REAL4_IS_SLOW
753    
754    checkpoint52 = ecco_c52_e35
755    o after testing adjoints of checkpoint51u_post
756    
757    checkpoint51u_post
758    o this is the post-merge tag of the ecco-branch
759      (needs another clean checkout and re-testing)
760    o various natl_box_adjoint configs and results
761      but no input fields
762    o obcs adjoint not yet merged!
763    o adding ECCO global 1x1 and 2x2 degree configs
764    o updated/extended some store directives for seaice
765    o pkg/ecco now containes ecco-specific part of cost function
766    o top level routines the_main_loop, forward_step
767      supersede those in model/src/
768      previous input data.cost now in data.ecco
769      (new namelist ecco_cost_nml)
770    o in ctrl/ cleaned some cross-dependencies and updated CPP options
771    
772    checkpoint51t_post
773    o this is the pre-merge tag of the ecco-branch
774    
775    checkpoint51s_post
776    o cleanup: removed various obsolete #define-s
777    o pkg/grdchk
778      - renamed 'ph-grd 3' to 'grad-res'
779      - merged from ecco-branch
780        (remaining bug fixes for obcs gradient checks)
781      - additional high-precision output for testreport
782        (grep for 'precision_grdchk_result')
783    
784    checkpoint51r_post
785    o cleaned up or removed CPP_OPTIONS.h files
786    o updated results for some of the tests to reflect the new

790    o cd_code:
791      - moved cd_scheme.F -> cd_code_scheme.F
792      - separate read_checkpoint from cd_code_ini_vars.F
793      - separated cd_code part from write_checkpoint
794      - updated AD_SOURCE, generated .flow
795      - added CD_CODE_VARS.h to the_main_loop
796      - Moving cd_code specific store dir.s to pkg/cd_code
797    o ctrl package totally restructured
798      - pack/unpack now optional and decoupled from
799        xx_/adxx_ I/O
800      - ctrl_pack/unpack cleaned
801        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
802      - confined inclusion of AD_CONFIG.h to where necessary.
803    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
804    
805    checkpoint51p_post
806    o create initial cd_code package
807      - WARNING: the initialization of fields within packages
808        is broken because INI_FIELDS (where READ_CHECKPOINT is
809        called) is called *before* PACKAGES_INIT_VARIABLES.
810        This seems to be backwards since
811        1) its important to initially zero the entire field including
812           the "halo" region
813        2) zeroing needs to be done *before* reading pickup info
814           and the pickup call might or might not happen in any
815           particular run
816      - this needs an overhaul for R2
817    o cleanup verification/*/code/GMREDI_OPTIONS.h
818    o cleanup testreport
819    
820    checkpoint51o_post
821    o bringing AD-related verif's up to date with genmake2
822      - carbon/
823      - global_ocean.90x40x15/
824      - hs.94.1x64x5/
825      - (front_relax/ )
826    o (more) consistent directory structure for AD-related verif.'s
827    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
828    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
829    o bug fix in find_alpha.F for MDJWF:
830      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
831        change rho -> rho-rhoConst
832      - replace call find_rho to find_rhonum
833    o initialisation of rFlx extended to full array (required by TAF)
834      and shifted to thermodynamics
835    o removed PTRACERS.h in ptracers routine
836    o added surfacetendencyPtr to S/R parameter list pracers_forcing
837    o Correcting initialisations for fVerU, fVerV.
838    o helping TAF to recognize dependency on kUp for
839      fVerU, fVerV
840    o Replacing delZ by delR in pkg/ctrl/
841    checkpoint51o_pre
842    
843    o undid all of cp51 pending some cleanups and discussion
844    o added the [#include "AD_CONFIG.h"] statement to all files that need
845       it for adjoint/tl #defines
846     o re-worked the build logic in genmake2 to support AD_CONFIG.h
847     o removed tools/genmake since it no longer works
848    
849    checkpoint51n_post
850    o modifications to make FREEZE flux visible to pkg/kpp
851      - moved surfaceTendencyTice from pkg/seaice to main code
852      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
853      - subroutine FREEZE now limits only surface temperature
854        (this means new output.txt for global_ocean.90x40x15,
855         global_ocean.cs32x15, and global_with_exf)
856    o added surface flux output variables to TIMEAVE_STATVARS
857    
858    checkpoint51n_pre
859  o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F  o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
860  o added [#include "AD_CONFIG.h"] to all files that use the following  o added [#include "AD_CONFIG.h"] to all files that use the following
