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

382    o new version of coupler for AIM+thSIce and Ocean models
383     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
384     - land: change Evaporation of snow
385     - aim with thSIce: fix bug in snow-precip.
386    o changes to calc_gw.F
387     - bug fix for w^2 term near the bottom boundary
388     - (hopefully) improve the lateral slip boundary condtions for use with
389        partial/looped cells
390      - because the bug fix changes two verification experiments anyway (exp5
391        and plume on slope), change the lateral boundary condition from half slip
392        to the value of no_slip_sides
393    o ebm package wasnt quite up to the parallel task. Fixed that.
394    o Adjoint of EBM package + verification
395      * TLM OK
396      * ADM not sufficient accuracy yet (needs further testing)
397
