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