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

455    o Will need long integration testing.
456  checkpoint53b_pre  checkpoint53b_pre
457
