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