3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o add CF-style coordinate variables to MNC
7      - just a first cut:  numbers are meaningless on the cubesphere and
8        missing along the T axis but otherwise it works!
9    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
10    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
11    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
12      this is based directly on what the model compute, so that the content of
13      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
14    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
15    o clean up build options files for SunOS, in particular
16      - remove -traditional from xmakedepend
17      - change -xarch=v9 to -xarch=native for f77
18      - restore use of make (not gmake)
19      - add CC=gcc if using g77
20    o changes per discussion of AM, JMC, & EH3 today:
21      - move redundant "grid" variables out of "state" -- in preparation of
22        creating proper CF-style coordinate variables and in recognition
23        that any/all grid variables can be easily copied (eg. w/NCO) from
24        the grid files into any of the other NetCDF files
25      - *always* output grid variables with MDSIO (this will eventually be
26        changed)
27      - output MNC grid file if useMNC is true
28    o every instance of _END_MASTER() has been found and replaced with
29      _END_MASTER( myThid ) in order to satisfy certain picky Sun
30      preprocessors
31    o re-arrange diagnostics pkg initialisation:
32     - allow each package to extend the available diagnostics list
33     - add some checking and fix small problems (multi-threaded, ...)
34     - new S/R diagnostics_fill (replace fill_diagnostics):
35       look through the short list of active diag. (instead of the long list)
36       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
37    
38    checkpoint57a_post
39    o this set of changes restores TAMC compatibility
40      tested for global_ocean.90x40x15 adjoint on trough
41      (what a pain)
42    
43    checkpoint57a_pre
44    o some modifs in tools/build_options for sunos
45    o call ctrl_pack for ctrl at end for optimcycle=0
46    
47    checkpoint57
48    o add horizontal bi-harmonic viscosity for vertical velocity
49      - new parameter viscA4W (defaults to viscA4)
50      - affects only non-hydrostatic code
51      - to be done: no-slip lateral boundary conditions
52    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
53    o implement Implicit Vertical advection for pTracers
54    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
55      (implemented also for implicit vertical diffusion & advection)
56    o OBCS: extend application of tracer open boundary conditions
57      to a strip beyond the boundary of width Olx/Oly
58    o add call monitor to TAF set of required calls (flow directives)
59      and include in natl_box_adjoint
60    o untangle a few ifdefs related to cost, ctrl, autodiff
61      untangel a few ALLOW_ECCO_OPTIMIZATION
62    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
63      (theta2, salt2 in ecco_cost_weights)
64    
65    checkpoint56c_post
66    o OBCS as control variables
67      - update ctrl_ad_diff.list, obcs_ad_diff.list
68      - remove balance of obcs controls from default
69      - fix index bug nobcs in ctrl_init
70      - fix dummy fields filen in ctrl_pack
71      - add dummy weights for obcs
72    o lsopt: comment out fort.94 output
73    o optim:
74      - remove unnecessary header files
75      - adjusted namelists
76      - add xerbla.F to Makefile
77    o exf:
78      - multiple modifications of exf_check_range
79      - unit change in exf_init_runoff from [m/year] to [m/s]
80    o mdsio:
81      - i/o-vector change debugLevel from debLevA to debLevB
82    
83    checkpoint56b_post
84    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
85      is called from DO_THE_MODEL_IO
86      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
87      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
88      - clean up PTRACERS_WRITE_TIMEAVE a little
89    o add another verification experiment that tests both the cfc-pkg and
90      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
91      reactive tendencies treated inline with regular timestepping
92    o testreport previously did a lousy job of comparing small numbers, so
93      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
94      implemented in the little c-progam tmp_cmpnum.c which is embedded in
95      testreport.
96    o ptracers_monitor: bug fix for MPI
97    
98    checkpoint56a_post
99    o GCHEM: finish reorganizating the package
100      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
101        (introduces another 3D-array for each passive tracer, but only if
102        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
103        gchemTendency is not needed because the timestep is done separately)
104      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
105      - GCHEM is now---more or less cleanly---separate from PTRACERS
106      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
107        so clear to me how that should be done in a general way.
108    o CFC: improve formatting of output in CFC_ATMOS
109    o PTRACERS:
110      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
111        that ALL experiments with ptracers enable can be checked. This makes
112        GCHEM_MONITOR obsolete.
113      - include a runtime parameter PTRACERS_monitorFreq that defaults to
114        monitorFreq
115      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
116    o add PTRACERS (PTR0[1-5]) to testreport output
117    o exf_check_range:
118      * default changed to .TRUE.
119      * will check values for niter0 if debLevA, every timestep if debLevB
120      * STOP in exf_check_range if 'out of range'
121      * range chosen generous to allow for potential extema
122      TBD: a version with stricter range
123           permitted range would be runtime parameters
124    o GMredi:
125      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
126      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
127      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
128    o GCHEM:
129      - move call to GCHEM_FORCING_SEP, so that it is now called before
130        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
131      - introduced a useGCHEM runtime flag and applied it everywhere.
132      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
133        this flag is now only visible within GCHEM-pkg routines.
134      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
135        be replaced by a 3D array that is computed before thermodynamics; for
136        this, the tracer ID iTracer had to be included into the parameter list
137        of ptracers_forcing
138      - set up forward_step to call gchem_forcing, that will replace
139        gchem_forcing_int in ptracers_forcing
140      - cleaning up
141    o small cleaning of exch2: remove files that are also in eesupp/src
142    
143    checkpoint56
144    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
145    o mnc: cleanup "full" files--fixes out-of-memory problem
146    o ECCO-GODAE
147      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
148      * fully merged and updated from SIO code
149        windstress sign change affects
150        - exf_inscal_[u/v]stress
151        - sign of xx_tau[u/v] adjustments
152        - signs in cost_scat
153      * ctrl_get_gen: avoid update of tau[u/v] for first few days
154      * natl_box_adjoint updated and compressed
155      * 2-level checkpoint switch added
156        (tested in EXP. 1 of natl_box_adjoint)
157      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
158    o SVD
159      * first complete, non-hacked version for SVD calculations
160      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
161        performed via direct access files admtlm_vector.it????
162        (via ctrl_[un]pack)
163      * optimcycle is used for ARPACK iteration counter
164        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
165      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
166        and add linear transforms where necessary
167      * controls are initial/final SST, SSS (can be extended; need to check
168        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
169    o mdsio: filename info to both stderr, stdout
170    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
171      from sign change
172    
173    checkpoint55j_post
174    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
175      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
176    o add consistent build directories and .cvsignore files to verification
177    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
178    o make all subroutines 30 or less characters in length for certain older
179      compilers to work (a thorough search only turns up two routines in
180      pkg/ptracers)
181    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
182      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
183    
184    checkpoint55i_post
185    o change arrays for total vertical diffusivity (2.D if explicit,
186      3.D if implicit) ; each ptracer uses its own background value.
187    o added mnc/NetCDF output capability to ocn_compon_interf
188      - added bits to verification/cpl_aim+ocn so that it can run on
189        ITRDA and other clusters without the mpirun "-wd" option
190    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
191      configuration
192    o give MNC the ability to create additional files rather than
193      exceeding a specified file size limit "MNC_MAX_FILESIZE"
194      - the default is just less than 2GB which is a practical limit
195        on many systems
196    o Compute the non-local term using either KPP vertical diffusivity (=default)
197       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
198    
199    checkpoint55h_post
200    o add verification test "vermix"
201    o remove all the *_ioinc flags and replace with the single global
202      outputTypesInclusive flag
203    o allow to set a vertical profile of vertical diffusivity for T & S
204    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
205    o useMNC moved from data.mnc to data.pkg
206    
207    checkpoint55g_post
208    o Renaming carbon AD experiments to comply with testreport conventions
209    o Updating adjoint of Held-Suarez hs94.1x64x5
210    o Fixing directives for non-ECCO forward_step, after ECCO directives
211      have been fixed to avoid recomp. of do_oceanic_phys
212      Works well for global_ocean.90x40x15,
213      but recomp. issue remains for carbon
214    o Updating adjoint output for natl_box_adjoint after
215      pkg/ecco has been modified (see taga c55d_post)
216    
217    checkpoint55f_post
218    o rename to timeave_init_fixed
219    
220    checkpoint55e_post
221    o some delicate re-shuffle of store directives to avoid one
222      extra call of do_oceanic_physics
223      affects ecco_the_main_loop.F, do_oceanic_physics.F
224      checkpoint_lev1_directives.h
225    o NB: this may break global_ocean adjoint temporarily,
226      but it is clear how to fix it. Will do later, need this now.
227    
228    checkpoint55d_post
229    o ECCO specific cost function terms (up-to-date with 1x1 runs)
230    o ecco_cost_weights is modified to 1x1 runs
231    o modifs to allow observations to be read in as
232      single file or yearly files
233    o enable to read exf forcing fields as either
234      single file or yearly files (flag useExfYearlyFields)
235    checkpoint55d_pre
236    
237    o switch between 2-level and 3-level checkpointing
238    o add ability of MNC to write local and "partial" (eg. 2D slices where
239      the full 3D field is never actually stored) arrays to NetCDF files
240      with the correct (that is, the complete multi-dimensional) set of
241      array indicies
242      - used in mom_vecinv() to write the diagFreq output
243      - tested (demonstrated) in verification/aim.5l_cs
244    o further mnc-ification
245      - add verification/lab_sea to the list with mnc setups
246      - fix undefined mnc v-names in cd_code
247      - add kpp to mnc output (both snapshot and timeave)
248    o non-hydrostatic code
249      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
250        in calc_gw.F
251      - defaults to viscAh
252      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
253        friction or Leith) in non-hydrostatic mode, as long as there is
254        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
255    o pkg/cost
256      extend simple cost functions to treat time mean quantities
257      (T,U,V) via cost_accumulate_state from cost_tile
258    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
259        be 2 times larger than the minimum size the advection scheme requires.
260        now get a perfect conservation of salt in advect_cs test-exp (updated)
261    o GGL90 (Gaspar's TKE mixed layer)
262      - add horizontal diffusion of TKE, requires exchanges in
263        do_fields_blocking_exchanges, horizontal diffusivity is zero by
264        default. In OPA there is no horizontal diffusion of TKE but the
265        mixing coefficients are computed from a horizontal average of TKE of
266        6 points or so. I think that diffusion has a little more physical
267        justification.
268      - clean up ggl90_calc in the hope of reducing memory usage (this hope
269        was in vain)
270      - mask tke-variable in ggl90_init
271    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
272    o fix biharmonic diffusion on CS-grid.
273    o more obcs stuff
274      - added obcs_external_fields_load as an alternative to the EXF-pkg option
275        for reading boundary values. This routine is called from
276        obcs_prescribe_read
277      - updated obcs_check
278      - changed sponge layer relaxation parameter units for days to seconds
279      - turned off sponge layer by default
280      - changed argument list of OBCS_CALC to myTime+deltaTclock
281      - fixed about 35 bugs in obcs_external_fields_load
282    
283    checkpoint55c_post
284    o obcs stuff
285      - new runtime flags useOBCSprescribe, useOBCSbalance
286      - re-arranged obcs_calc
287      - moved exf_getobcs to obcs_prescibe_read
288        obcs_prescibe_read is called after ORLANSKI stuff
289        and independent of it (executable can contain all).
290      - updated obcs_check
291      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
292        These may be necessary only if tangential velocities are
293        prescribed at OB, not sure, needs testing.
294    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
295      which simplifies the calls and passes the ifc check-bounds test
296    
297    checkpoint55b_post
298    o add a 2D scalar, Z location, exchange_2 routine.
299    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
300      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
301      affects advect_cs results (for the wrong reason): update output.txt
302    o use a more standard discretization for biharmonic viscosity ;
303     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
304      affects results of dome set-up: update output.txt
305    o fix gad_advection.F (CubedSphere part), back to version 1.23
306    o fix bug in mom_vi_del2uv.F (CubedSphere part).
307    
308    checkpoint55a_post
309    o merged code to
310      * prescribe/read time-dependent open boundaries
311        (works in conjunction with exf, cal)
312      * sponge layer code for open boundaries
313      * each boundary N/S/E/W now has its own CPP option
314        (healthy for the adjoint)
315    
316    checkpoint55
317    o up-to-date adjoint of previous breaks
318      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
319      - global_ocean_ebm: adjoint still needs fix (TLM ok)
320      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
321      - carbon: * remove tr1-related adjoint verification
322                * add ptracer as control variable
323    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
324      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
325    
326    checkpoint54f_post
327    o in verification/carbin/ remove experiment related to
328      ALLOW_PASSIVE_TRACER (array tr1 etc)
329      code_ad/ input_ad/ results_ad
330    
331    o add two new packages
332      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
333        + subject to optimization (memory)
334      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
335        + subject to reordering (many GOTOs in the original code)
336        + so far opps is called for every (i,j) point, and then operates in
337          the vertical; one may want to reorder the scheme in order operate in
338          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
339          fields)
340    o overhaul of IO so that we now have flags for MDSIO and/or MNC
341      - all verification tests compile and run with linux_ia32_g77
342      - defaults are compatible with current input files--nothing
343        should change if you were not previously using MNC
344      - MNC output has been added in numerous places (eg. timeave)
345        but there are still a few writes not yet do-able with MNC
346        (this is in progress)
347      - flags now allow for either/or/both use of MDSIO and MNC and
348        documentation will soon follow
349      - numerous small formatting cleanups for ProTeX
350    o add version info (via BUILD_INFO.h) to MNC and stdout
351    
352    checkpoint54e_post
353    o add two new packages
354      - pp81 (Packanowski and Philander, 1981), Richardson number and
355        stratification dependent mixing
356      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
357      - these scheme operate in a similar manner as KPP (without ghat, of
358        course), however there is only one diffusivity that is used for both
359        temperature and salinity (and passive tracers)ç
360    o add offline package
361    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
362      provided by Stephanie Dutkiewicz
363    o genmake2: add ability to search for C compilers and cleanup test output
364      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
365    
366    checkpoint54d_post
367    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
368    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
369      leading to additional shift by 5 days each year of integration
370       (i.e. leading to considerable offset over the years)
371    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
372    o start with no AB and no initial filtering (staggerTimeStep):
373      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
374    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
375      (external loading & cpl import/export stay in forward_step.F)
376    o update coupling interface to work with new staggerTimeStep
377    o change MDSIO ptracers_pickup.
378    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
379    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
380    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
381    
382    checkpoint54c_post
383    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
384      this affects (truncation error) output.txt of test-exp:
385       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
386    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
387    o change Qnet to always be the net heat flux, (+upward).
388      affects (truncation error) output of natl_box exp.: updated
389    o define the max number of passive tracers in PTRACERS_SIZE.h
390    o start to test mnc routinely in exp0
391    o add sea-ice loading (sIceLoad) as a new forcing field.
392    
393    checkpoint54b_post
394    o add testreport "-j JOBS" option for parallel builds (tested and pretty
395       impressive on Altix and Opteron systems)
396    o diagnostics can now write NetCDF files through the mnc package
397    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
398    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
399    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
400      affects (truncation error) output of lab_sea & natl_box exp.: updated
401    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
402    
403    checkpoint54a_post
404    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
405    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
406    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
407    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
408      + internal_wave (shift in writing cg2d_ini_res)
409    checkpoint54a_pre
410    
411  o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice  o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
412    - modified verification/lab_sea and natl_box_adjoint accordingly    - modified verification/lab_sea and natl_box_adjoint accordingly
