3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
7    
8    checkpoint57d_post
9    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
10    o modify verification/ideal_2D_oce so that it tests the creation of mnc
11      output from the diagnostics package
12    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
13    o make genmake2 more portable by using ".$FS" instead of ".f" for more
14      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
15    o add coordinate variables to the MNC output from the diagnostics package
16    o change MNC-flags default value: true when useMNC=TRUE
17    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
18      the ability (off by default) to read the grid information using MNC
19    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
20    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
21    o do snap-shot diagnostics at the middle of the time-interval (instead of
22      at the end).
23    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
24      new test for AIM with thSIce + slab-ocean
25    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
26    o move state variable diagnostics to the beginning of the time step ;
27      (note: still needs some work specially for snap-shot diagnostics)
28      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
29    
30    checkpoint57c_post
31    o Change testing option (-ieee) to get closer agreement between g77 & ifort
32    o generate new output.txt files on faulks with g77 & the new -ieee option
33    checkpoint57c_pre
34    
35    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
36      update output.txt of exp. global_ocean.90x40x15
37    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
38      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
39    o add saltFlux(+File) forcing capability with periodicExternalForcing
40    o allow to use pkg diagnostics for GM-Redi & ThSIce output
41    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
42    o improvements for the MNC output from DIAGNOSTICS:
43      - correct handling of the unlimitied dimension
44      - all dims now have associated coordinate variables
45      - variables located at U, V, and Corner ("Z") points are now written
46        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
47        *all* data points are output
48    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
49    o added pkg/seaice/seaice_monitor.F
50    o mdsio_readfield.F can now read files visible only to master MPI process.
51    o pkg/seaice: some test code for ice-modified ocean stress
52    o exf_getffields interpolation defaults to bilinear for all scalar forcing
53      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
54      spurious negative numbers for precipitation and humidity.  Will cause
55      some small numerical differences for integrations using pkg/exf/exf_interp.F.
56    o pkg/ctrl/
57      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
58        May be enabled via doPackDiag
59      *  introduce z-scaling of
60         + gradient (doZscalePack) and
61         + control (doZscaleUnpack)
62    o pkg/mdsio/
63      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
64      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
65    
66    checkpoint57b_post
67    o simplify options in diagnostics_fill arguments (remove weird combinations)
68    o fix MNC coordinate variables so that they now contain per-face index
69      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
70      general, EXCH2 grids are only aligned to a "local" coordinate system
71    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
72    o Implement instantaneous output within pkg diagnostics:
73      setting a negative frequency in data.diagnostics produces
74     "snap-shot" output (as opposed to time-average if freq > 0)
75    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
76      NOTE: change ptracer diagnostics name: use 2 characters to work with
77            more than 9 tracers. Add also diagnostics of advect & diffus flux.
78    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
79      becomes the coordinate variable for the 'T' dimension
80    o add CF-style coordinate variables to MNC
81      - just a first cut:  numbers are meaningless on the cubesphere and
82        missing along the T axis but otherwise it works!
83    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
84    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
85    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
86      this is based directly on what the model compute, so that the content of
87      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
88    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
89    o clean up build options files for SunOS, in particular
90      - remove -traditional from xmakedepend
91      - change -xarch=v9 to -xarch=native for f77
92      - restore use of make (not gmake)
93      - add CC=gcc if using g77
94    o changes per discussion of AM, JMC, & EH3 today:
95      - move redundant "grid" variables out of "state" -- in preparation of
96        creating proper CF-style coordinate variables and in recognition
97        that any/all grid variables can be easily copied (eg. w/NCO) from
98        the grid files into any of the other NetCDF files
99      - *always* output grid variables with MDSIO (this will eventually be
100        changed)
101      - output MNC grid file if useMNC is true
102    o every instance of _END_MASTER() has been found and replaced with
103      _END_MASTER( myThid ) in order to satisfy certain picky Sun
104      preprocessors
105    o re-arrange diagnostics pkg initialisation:
106     - allow each package to extend the available diagnostics list
107     - add some checking and fix small problems (multi-threaded, ...)
108     - new S/R diagnostics_fill (replace fill_diagnostics):
109       look through the short list of active diag. (instead of the long list)
110       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
111    
112    checkpoint57a_post
113    o this set of changes restores TAMC compatibility
114      tested for global_ocean.90x40x15 adjoint on trough
115      (what a pain)
116    
117    checkpoint57a_pre
118    o some modifs in tools/build_options for sunos
119    o call ctrl_pack for ctrl at end for optimcycle=0
120    
121    checkpoint57
122    o add horizontal bi-harmonic viscosity for vertical velocity
123      - new parameter viscA4W (defaults to viscA4)
124      - affects only non-hydrostatic code
125      - to be done: no-slip lateral boundary conditions
126    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
127    o implement Implicit Vertical advection for pTracers
128    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
129      (implemented also for implicit vertical diffusion & advection)
130    o OBCS: extend application of tracer open boundary conditions
131      to a strip beyond the boundary of width Olx/Oly
132    o add call monitor to TAF set of required calls (flow directives)
133      and include in natl_box_adjoint
134    o untangle a few ifdefs related to cost, ctrl, autodiff
135      untangel a few ALLOW_ECCO_OPTIMIZATION
136    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
137      (theta2, salt2 in ecco_cost_weights)
138    
139    checkpoint56c_post
140    o OBCS as control variables
141      - update ctrl_ad_diff.list, obcs_ad_diff.list
142      - remove balance of obcs controls from default
143      - fix index bug nobcs in ctrl_init
144      - fix dummy fields filen in ctrl_pack
145      - add dummy weights for obcs
146    o lsopt: comment out fort.94 output
147    o optim:
148      - remove unnecessary header files
149      - adjusted namelists
150      - add xerbla.F to Makefile
151    o exf:
152      - multiple modifications of exf_check_range
153      - unit change in exf_init_runoff from [m/year] to [m/s]
154    o mdsio:
155      - i/o-vector change debugLevel from debLevA to debLevB
156    
157    checkpoint56b_post
158    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
159      is called from DO_THE_MODEL_IO
160      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
161      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
162      - clean up PTRACERS_WRITE_TIMEAVE a little
163    o add another verification experiment that tests both the cfc-pkg and
164      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
165      reactive tendencies treated inline with regular timestepping
166    o testreport previously did a lousy job of comparing small numbers, so
167      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
168      implemented in the little c-progam tmp_cmpnum.c which is embedded in
169      testreport.
170    o ptracers_monitor: bug fix for MPI
171    
172    checkpoint56a_post
173    o GCHEM: finish reorganizating the package
174      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
175        (introduces another 3D-array for each passive tracer, but only if
176        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
177        gchemTendency is not needed because the timestep is done separately)
178      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
179      - GCHEM is now---more or less cleanly---separate from PTRACERS
180      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
181        so clear to me how that should be done in a general way.
182    o CFC: improve formatting of output in CFC_ATMOS
183    o PTRACERS:
184      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
185        that ALL experiments with ptracers enable can be checked. This makes
186        GCHEM_MONITOR obsolete.
187      - include a runtime parameter PTRACERS_monitorFreq that defaults to
188        monitorFreq
189      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
190    o add PTRACERS (PTR0[1-5]) to testreport output
191    o exf_check_range:
192      * default changed to .TRUE.
193      * will check values for niter0 if debLevA, every timestep if debLevB
194      * STOP in exf_check_range if 'out of range'
195      * range chosen generous to allow for potential extema
196      TBD: a version with stricter range
197           permitted range would be runtime parameters
198    o GMredi:
199      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
200      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
201      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
202    o GCHEM:
203      - move call to GCHEM_FORCING_SEP, so that it is now called before
204        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
205      - introduced a useGCHEM runtime flag and applied it everywhere.
206      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
207        this flag is now only visible within GCHEM-pkg routines.
208      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
209        be replaced by a 3D array that is computed before thermodynamics; for
210        this, the tracer ID iTracer had to be included into the parameter list
211        of ptracers_forcing
212      - set up forward_step to call gchem_forcing, that will replace
213        gchem_forcing_int in ptracers_forcing
214      - cleaning up
215    o small cleaning of exch2: remove files that are also in eesupp/src
216    
217    checkpoint56
218    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
219    o mnc: cleanup "full" files--fixes out-of-memory problem
220    o ECCO-GODAE
221      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
222      * fully merged and updated from SIO code
223        windstress sign change affects
224        - exf_inscal_[u/v]stress
225        - sign of xx_tau[u/v] adjustments
226        - signs in cost_scat
227      * ctrl_get_gen: avoid update of tau[u/v] for first few days
228      * natl_box_adjoint updated and compressed
229      * 2-level checkpoint switch added
230        (tested in EXP. 1 of natl_box_adjoint)
231      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
232    o SVD
233      * first complete, non-hacked version for SVD calculations
234      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
235        performed via direct access files admtlm_vector.it????
236        (via ctrl_[un]pack)
237      * optimcycle is used for ARPACK iteration counter
238        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
239      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
240        and add linear transforms where necessary
241      * controls are initial/final SST, SSS (can be extended; need to check
242        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
243    o mdsio: filename info to both stderr, stdout
244    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
245      from sign change
246    
247    checkpoint55j_post
248    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
249      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
250    o add consistent build directories and .cvsignore files to verification
251    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
252    o make all subroutines 30 or less characters in length for certain older
253      compilers to work (a thorough search only turns up two routines in
254      pkg/ptracers)
255    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
256      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
257    
258    checkpoint55i_post
259    o change arrays for total vertical diffusivity (2.D if explicit,
260      3.D if implicit) ; each ptracer uses its own background value.
261    o added mnc/NetCDF output capability to ocn_compon_interf
262      - added bits to verification/cpl_aim+ocn so that it can run on
263        ITRDA and other clusters without the mpirun "-wd" option
264    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
265      configuration
266    o give MNC the ability to create additional files rather than
267      exceeding a specified file size limit "MNC_MAX_FILESIZE"
268      - the default is just less than 2GB which is a practical limit
269        on many systems
270    o Compute the non-local term using either KPP vertical diffusivity (=default)
271       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
272    
273    checkpoint55h_post
274    o add verification test "vermix"
275    o remove all the *_ioinc flags and replace with the single global
276      outputTypesInclusive flag
277    o allow to set a vertical profile of vertical diffusivity for T & S
278    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
279    o useMNC moved from data.mnc to data.pkg
280    
281    checkpoint55g_post
282    o Renaming carbon AD experiments to comply with testreport conventions
283    o Updating adjoint of Held-Suarez hs94.1x64x5
284    o Fixing directives for non-ECCO forward_step, after ECCO directives
285      have been fixed to avoid recomp. of do_oceanic_phys
286      Works well for global_ocean.90x40x15,
287      but recomp. issue remains for carbon
288    o Updating adjoint output for natl_box_adjoint after
289      pkg/ecco has been modified (see taga c55d_post)
290    
291    checkpoint55f_post
292    o rename to timeave_init_fixed
293    
294    checkpoint55e_post
295    o some delicate re-shuffle of store directives to avoid one
296      extra call of do_oceanic_physics
297      affects ecco_the_main_loop.F, do_oceanic_physics.F
298      checkpoint_lev1_directives.h
299    o NB: this may break global_ocean adjoint temporarily,
300      but it is clear how to fix it. Will do later, need this now.
301    
302    checkpoint55d_post
303    o ECCO specific cost function terms (up-to-date with 1x1 runs)
304    o ecco_cost_weights is modified to 1x1 runs
305    o modifs to allow observations to be read in as
306      single file or yearly files
307    o enable to read exf forcing fields as either
308      single file or yearly files (flag useExfYearlyFields)
309    checkpoint55d_pre
310    
311    o switch between 2-level and 3-level checkpointing
312    o add ability of MNC to write local and "partial" (eg. 2D slices where
313      the full 3D field is never actually stored) arrays to NetCDF files
314      with the correct (that is, the complete multi-dimensional) set of
315      array indicies
316      - used in mom_vecinv() to write the diagFreq output
317      - tested (demonstrated) in verification/aim.5l_cs
318    o further mnc-ification
319      - add verification/lab_sea to the list with mnc setups
320      - fix undefined mnc v-names in cd_code
321      - add kpp to mnc output (both snapshot and timeave)
322    o non-hydrostatic code
323      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
324        in calc_gw.F
325      - defaults to viscAh
326      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
327        friction or Leith) in non-hydrostatic mode, as long as there is
328        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
329    o pkg/cost
330      extend simple cost functions to treat time mean quantities
331      (T,U,V) via cost_accumulate_state from cost_tile
332    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
333        be 2 times larger than the minimum size the advection scheme requires.
334        now get a perfect conservation of salt in advect_cs test-exp (updated)
335    o GGL90 (Gaspar's TKE mixed layer)
336      - add horizontal diffusion of TKE, requires exchanges in
337        do_fields_blocking_exchanges, horizontal diffusivity is zero by
338        default. In OPA there is no horizontal diffusion of TKE but the
339        mixing coefficients are computed from a horizontal average of TKE of
340        6 points or so. I think that diffusion has a little more physical
341        justification.
342      - clean up ggl90_calc in the hope of reducing memory usage (this hope
343        was in vain)
344      - mask tke-variable in ggl90_init
345    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
346    o fix biharmonic diffusion on CS-grid.
347    o more obcs stuff
348      - added obcs_external_fields_load as an alternative to the EXF-pkg option
349        for reading boundary values. This routine is called from
350        obcs_prescribe_read
351      - updated obcs_check
352      - changed sponge layer relaxation parameter units for days to seconds
353      - turned off sponge layer by default
354      - changed argument list of OBCS_CALC to myTime+deltaTclock
355      - fixed about 35 bugs in obcs_external_fields_load
356    
357    checkpoint55c_post
358    o obcs stuff
359      - new runtime flags useOBCSprescribe, useOBCSbalance
360      - re-arranged obcs_calc
361      - moved exf_getobcs to obcs_prescibe_read
362        obcs_prescibe_read is called after ORLANSKI stuff
363        and independent of it (executable can contain all).
364      - updated obcs_check
365      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
366        These may be necessary only if tangential velocities are
367        prescribed at OB, not sure, needs testing.
368    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
369      which simplifies the calls and passes the ifc check-bounds test
370    
371    checkpoint55b_post
372    o add a 2D scalar, Z location, exchange_2 routine.
373    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
374      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
375      affects advect_cs results (for the wrong reason): update output.txt
376    o use a more standard discretization for biharmonic viscosity ;
377     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
378      affects results of dome set-up: update output.txt
379    o fix gad_advection.F (CubedSphere part), back to version 1.23
380    o fix bug in mom_vi_del2uv.F (CubedSphere part).
381    
382    checkpoint55a_post
383    o merged code to
384      * prescribe/read time-dependent open boundaries
385        (works in conjunction with exf, cal)
386      * sponge layer code for open boundaries
387      * each boundary N/S/E/W now has its own CPP option
388        (healthy for the adjoint)
389    
390    checkpoint55
391    o up-to-date adjoint of previous breaks
392      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
393      - global_ocean_ebm: adjoint still needs fix (TLM ok)
394      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
395      - carbon: * remove tr1-related adjoint verification
396                * add ptracer as control variable
397    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
398      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
399    
400    checkpoint54f_post
401    o in verification/carbin/ remove experiment related to
402      ALLOW_PASSIVE_TRACER (array tr1 etc)
403      code_ad/ input_ad/ results_ad
404    
405    o add two new packages
406      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
407        + subject to optimization (memory)
408      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
409        + subject to reordering (many GOTOs in the original code)
410        + so far opps is called for every (i,j) point, and then operates in
411          the vertical; one may want to reorder the scheme in order operate in
412          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
413          fields)
414    o overhaul of IO so that we now have flags for MDSIO and/or MNC
415      - all verification tests compile and run with linux_ia32_g77
416      - defaults are compatible with current input files--nothing
417        should change if you were not previously using MNC
418      - MNC output has been added in numerous places (eg. timeave)
419        but there are still a few writes not yet do-able with MNC
420        (this is in progress)
421      - flags now allow for either/or/both use of MDSIO and MNC and
422        documentation will soon follow
423      - numerous small formatting cleanups for ProTeX
424    o add version info (via BUILD_INFO.h) to MNC and stdout
425    
426    checkpoint54e_post
427    o add two new packages
428      - pp81 (Packanowski and Philander, 1981), Richardson number and
429        stratification dependent mixing
430      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
431      - these scheme operate in a similar manner as KPP (without ghat, of
432        course), however there is only one diffusivity that is used for both
433        temperature and salinity (and passive tracers)ç
434    o add offline package
435    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
436      provided by Stephanie Dutkiewicz
437    o genmake2: add ability to search for C compilers and cleanup test output
438      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
439    
440    checkpoint54d_post
441    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
442    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
443      leading to additional shift by 5 days each year of integration
444       (i.e. leading to considerable offset over the years)
445    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
446    o start with no AB and no initial filtering (staggerTimeStep):
447      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
448    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
449      (external loading & cpl import/export stay in forward_step.F)
450    o update coupling interface to work with new staggerTimeStep
451    o change MDSIO ptracers_pickup.
452    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
453    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
454    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
455    
456    checkpoint54c_post
457    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
458      this affects (truncation error) output.txt of test-exp:
459       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
460    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
461    o change Qnet to always be the net heat flux, (+upward).
462      affects (truncation error) output of natl_box exp.: updated
463    o define the max number of passive tracers in PTRACERS_SIZE.h
464    o start to test mnc routinely in exp0
465    o add sea-ice loading (sIceLoad) as a new forcing field.
466    
467    checkpoint54b_post
468    o add testreport "-j JOBS" option for parallel builds (tested and pretty
469       impressive on Altix and Opteron systems)
470    o diagnostics can now write NetCDF files through the mnc package
471    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
472    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
473    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
474      affects (truncation error) output of lab_sea & natl_box exp.: updated
475    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
476    
477    checkpoint54a_post
478    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
479    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
480    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
481    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
482      + internal_wave (shift in writing cg2d_ini_res)
483    checkpoint54a_pre
484    
485    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
486      - modified verification/lab_sea and natl_box_adjoint accordingly
487    
488    checkpoint54
489    checkpoint53g_post
490    o prepare splitting of thermodynamics: store convect.counter in common block
491    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
492      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
493    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
494    o new parameter "nShapS": allow to treat differently S from T (nShapT)
495    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
496    o restore adjointability
497    
498    checkpoint53f_post
499    o modifications that affect AIM experiment results (update output.txt):
500      - no advection of S at top interface Nr (pkg/generic_advdiff)
501      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
502    o AIM pkg:
503      - include stability function into surf.Flux derivative relative to Tsurf
504      - calculate clear-sky radiation & surface temp. change (for diagnostics)
505    
506    checkpoint53e_post
507    o merged cylindrical coord configuration
508    o added rotating_tank experiment
509    checkpoint53e_pre
510    
511    checkpoint53d_post
512    o faulks upgraded: re-generate output.txt that have changed:
513       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
514    o Added Bryan and Lewis, 1979, vertical diffusivity profile
515    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
516    o added Sadourny discretization of Coriolis
517      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
518      - re-enabled use of omega3 (useAbsVorticity)
519    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
520      vector-invariant equations
521      - note: does *NOT* yet use same variable visc. for no-slip BC's.
522    o recoded the lateral boundary conditions for non-hydrostatic w, this time
523      hopefully without new bugs
524      - still to do: biharmonic friction for non-hydrostatic w
525    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
526    o regenerated output for global_ocean_ebm (using -ieee)
527    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
528      of mom_common/
529      - simple re-arrangement of instructions within computing loop
530    checkpoint53d_pre
531    
532    checkpoint53c_post
533    o new version of coupler for AIM+thSIce and Ocean models
534     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
535     - land: change Evaporation of snow
536     - aim with thSIce: fix bug in snow-precip.
537    o changes to calc_gw.F
538     - bug fix for w^2 term near the bottom boundary
539     - (hopefully) improve the lateral slip boundary condtions for use with
540        partial/looped cells
541      - because the bug fix changes two verification experiments anyway (exp5
542        and plume on slope), change the lateral boundary condition from half slip
543        to the value of no_slip_sides
544    o ebm package wasnt quite up to the parallel task. Fixed that.
545    o Adjoint of EBM package + verification
546      * TLM OK
547      * ADM not sufficient accuracy yet (needs further testing)
548    
549    checkpoint53b_post
550    o Commiting new energy balance model to repository
551      * package is pkg/ebm
552      * verif. is verification/global_ocean_ebm
553      * references are in ebm_driver.F
554    C      * X. Wang, P. Stone and J. Marotzke, 1999:
555    C        Global thermohaline circulation. Part I:
556    C        Sensitivity to atmospheric moisture transport.
557    C        J. Climate 12(1), 71-82
558    C      * X. Wang, P. Stone and J. Marotzke, 1999:
559    C        Global thermohaline circulation. Part II:
560    C        Sensitivity with interactive transport.
561    C        J. Climate 12(1), 83-91
562    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
563    C        Destabilization of the thermohaline circulation
564    C        by atmospheric eddy transports.
565    C        J. Climate 7(12), 1870-1882
566    o Will need long integration testing.
567    checkpoint53b_pre
568    
569    o created pkg/mom_common in preparation for variable viscosity code
570    o renamed and split ini_mnc_io
571    o pkg/land: only liquid water can diffuse or run-off
572    o AIM using land: soil wetness availability account for snow
573    o added printMapIncludesZeros to EEPARMS namelist
574    
575    checkpoint53a_post
576    o restore TAMC compatiility for exf_constants.h
577      (no usage of _d in .h)
578    o Additional storing in KPP in an attempt to fix
579      TAMC problem with adjoint of KPP code.
580      (no success...)
581      Identical code works fine with TAF.
582    o Fixed verification/natl_box_adjoint experiments.
583      Initial conditions for Experiments 4 and 5 are now
584      set to "SEAICE_initialHEFF=0", which is more reasonable,
585      and hence gives results closer to that of Experiment 2.
586      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
587    
588    checkpoint53
589    o stable checkpoint with up to date adjoint
590      TLM tests only run for 1st grdchk at the moment. Its unclear if
591      this is a code problem or a problem with resetting code for g_
592      variables that is being autogenerated wrong.
593      Otherwise:
594       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
595       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
596         are both still in chaos following their security messes.
597    
598    checkpoint52n_post
599    o various build (mostly genmake2) changes including:
600      - ability to build/run more easily within Cygwin and MacOS X
601      - more complicated Makefiles with a stronger dependence on Gnu Make
602    o pkg/seaice modifications
603      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
604        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
605        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
606      - changed proxy for geostrophic velocity and updated
607        verification/lab_sea/results/* accordingly
608      - removed ADI dynamic solver from pkg/seaice
609      - replaced all occurrences of 1/CSTICE or 1/CSUICE
610        they caused a segmentation fault under certain circumstances
611      - removed unused field WATR
612    o bug fix in exf-package:
613      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
614         now reflect that.
615    o small fixes in the cal-package:
616      - set reference date to first of January for the 'model'-calendar
617      - failing of cal_CheckDate in cal_FullDate now actually results in a
618        warning
619    o small modifications in exf-package to increase flexibility:
620      - change climtempfreeze from a constant to a runtime parameter that
621        is specified in data.exf_clim (default = -1.9)
622      - introduce runtime parameter windstressmax (default = 2.0) that is
623        specified in data.exf
624    o fix in pkg/thsice:
625      - update Evap (Tsf changes) to be consistent with Latent heat flux
626      - maintain snow precipitation unchanged (even if Tsf >=0).
627     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
628    
629    checkpoint52m_post
630    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
631      this does not change any of the results, because myIter=0 in swfrac always
632      lead to jwtype=2 (the default anyway), but the call makes little sense
633      as a default
634    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
635    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
636      atmospheric model (AIM) to use it ; add a "slab ocean" component.
637    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
638    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
639    o extending useSingleCpuIO option to work with new exch2 I/O format
640      - old-style, missing-tile I/O is still accessible by defining CPP
641        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
642    o monitor package can write to NetCDF files and/or STDOUT
643    o fix re-definition bug in MNC_GRID_INIT_ALL()
644    o doc/api_reference added
645      - a framework for building an API Reference Manual using all
646        the "protex" comments embedded in the code
647      - see pkg/generic_advdiff, pkg/mnc for examples
648    o MNC:
649      - make myThid the last argument for all subroutines
650      - new default for the grid files: NO halos
651      - add useMNC and other run-time flags
652      - separate per-file-group handling of the unlimited dimension
653      - early initialization of MNC w/ flags read at the eeboot stage
654        and lookup tables set in initialize_fixed
655      - write all MNC output to a freshly-created directory
656    o thermodynamics sea-ice (thsice) is now tested with testreport.
657    o test exp. advect_cs: use the standard cs32 grid ; update output.
658    o Added functionality to grdchk:
659      pick global i,j,k position (or nearest wet) where to perform check.
660    
661    checkpoint52l_post
662    o new land formulation:
663      a) use ground enthalpy as prognostic variable to ensure exact
664         energy conservation.
665      b) account for water temperature and for latent heat of freezing
666         in all processes (rain, run-off, ground storage)
667      c) compute surface and ground temperature implicitly.
668    o aim_v23 modification for new land model:
669      a) Treat separately land / ocean / sea-ice surface fluxes
670         to allow implicit computation of land & sea-ice surface temp.
671      b) add snow precipitation.
672    checkpoint52l_pre
673    
674    o fix problem (when 1 tile is empty) in min/max monitor.
675    o fix bug in timeAve (u,vZetatave in common block)
676    o no restoring terms under ice for pkg/seaice
677    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
678    o bug fix for pkg/seaice pickups
679    o change MNC call locations and add coordinate attributes
680    o mask vorticity at the corner ; affects global_ocean.cs output
681    o fix ini_curvilinear_grid ; test CS experiments with mpi
682    o aim.5l_cs: modify sea-ice fraction input file ; update output
683    o exf: Adding simple range check routine for exf fields after read
684    
685    checkpoint52k_post
686    o removed top-level directory "diags"
687      - we migrated these functions to pkg/timeave a long time ago
688    o fixed bug introduced in pkg/monitor
689    o accuracy ctrlprec = 32 insuffient for gradient checks using
690      averaged fields (I/O via cost_averages)
691      -> use ctrl.h in active_file*.F to control I/O precision.
692    o paramter list of CALL ADTHE_MAIN_LOOP
693    o added initial do_the_model_io to ecco
694    o set all ...Freq to zero after cost_final
695      taveFreq, dumpFreq, pChkptFreq
696    o MAIN and ECCO differentiability restored
697    
698    checkpoint52j_post
699    o fix nchklev in tamc.h for global_ocean...
700    o Bringing flow and store directives up-to-date
701    o Really weird thing!
702      call do_the_model_io from the_main_loop with parameters
703      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
704      TAF places a faulty re-call of initialise_varia
705      after cost_final call which should not be there!
706    checkpoint52j_pre
707    
708    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
709      error messages
710    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
711    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
712      debug output
713    o modfied mdsio_writefield.F to handle non-global files under exch2
714    o update AIM Cubed-Sphere exp (aim.5l_cs):
715      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
716    o update AIM Equatorial Channel exp:
717      use standard aim_v23 pkg and change the SST fields to be more realistic.
718    o globalFile now works with exch2
719    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
720      mon_vort3.F to make exch2 friendly with >1 tile per cube face
721    o limit timeave output for hi-res integrations
722    
723    checkpoint52i_post
724    o removed CPP_EEOPTIONS.h from verification/*/code
725    o updated the tiling for global_ocean_pressure
726    checkpoint52i_pre
727    
728    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
729      the old pkg/aim).
730    
731    checkpoint52h_pre
732    o shortened offending lines in exch2_send_rx?.template
733    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
734    o genmake2: add build & execute test for NetCDF code
735    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
736      old grid files, moved CPP_EEMACROS.h to pkg/exch2
737    o added useSingleCPUIO flag to monitor.F and mon_out.F
738    o added temporary hack for sea-ice dynamics on the cube:
739      metric terms are ignored and it is assumed that
740      there is no sea-ice on cube faces 1, 2, 4, and 5.
741    
742    checkpoint52f_post
743    o added exch2 cube routines to pkg/exch2
744    o modified hs94.cs-32x32x5 to use it
745    o added new grid files to hs94.cs-32x32x5
746    checkpoint52f_pre
747    
748    checkpoint52e_post
749    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
750      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
751    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
752      to work with implicit vertical advection and AB ;
753    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
754    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
755     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
756    checkpoint52e_pre
757
