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