3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
7      as well as grad(vort3).  Made it compatible with both approximate form
8      for the cubed sphere and full form of these gradients.  Added flag
9      useFullLeith to select between approximate and full form.  
10    o add "d0" in getcon.F to reduce differences between compilers/platforms
11      update output.txt of exp. fizhi-gridalt-hs
12    o change port_rand funtion to allow to set the seed.
13    o fix obscure MNC bug involving conversion between reals and integers
14      - it caused no problems with certain (eg. gcc, ifc) compilers but the
15        new version is now more standards-compliant
16    
17    checkpoint57e_post
18    o Adding eddy stress controls a la Ferreira et al.
19    checkpoint57e_pre
20    
21    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
22      update output.txt of exp. fizhi-gridalt-hs
23    o add more "Z" dimensions and associated coordinate vars to MNC
24    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
25    o parameter calendarDumps: when set, approximate months (30-31 days) and years
26      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
27      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
28      months and years.  Requires pkg/cal.
29    o diagnostics: add pickup functionality
30      - off by default for backwards compatibility
31      - current version only uses MDSIO -- MNC will be added
32    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
33    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
34    
35    checkpoint57d_post
36    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
37    o modify verification/ideal_2D_oce so that it tests the creation of mnc
38      output from the diagnostics package
39    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
40    o make genmake2 more portable by using ".$FS" instead of ".f" for more
41      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
42    o add coordinate variables to the MNC output from the diagnostics package
43    o change MNC-flags default value: true when useMNC=TRUE
44    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
45      the ability (off by default) to read the grid information using MNC
46    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
47    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
48    o do snap-shot diagnostics at the middle of the time-interval (instead of
49      at the end).
50    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
51      new test for AIM with thSIce + slab-ocean
52    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
53    o move state variable diagnostics to the beginning of the time step ;
54      (note: still needs some work specially for snap-shot diagnostics)
55      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
56    
57    checkpoint57c_post
58    o Change testing option (-ieee) to get closer agreement between g77 & ifort
59    o generate new output.txt files on faulks with g77 & the new -ieee option
60    checkpoint57c_pre
61    
62    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
63      update output.txt of exp. global_ocean.90x40x15
64    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
65      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
66    o add saltFlux(+File) forcing capability with periodicExternalForcing
67    o allow to use pkg diagnostics for GM-Redi & ThSIce output
68    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
69    o improvements for the MNC output from DIAGNOSTICS:
70      - correct handling of the unlimitied dimension
71      - all dims now have associated coordinate variables
72      - variables located at U, V, and Corner ("Z") points are now written
73        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
74        *all* data points are output
75    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
76    o added pkg/seaice/seaice_monitor.F
77    o mdsio_readfield.F can now read files visible only to master MPI process.
78    o pkg/seaice: some test code for ice-modified ocean stress
79    o exf_getffields interpolation defaults to bilinear for all scalar forcing
80      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
81      spurious negative numbers for precipitation and humidity.  Will cause
82      some small numerical differences for integrations using pkg/exf/exf_interp.F.
83    o pkg/ctrl/
84      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
85        May be enabled via doPackDiag
86      *  introduce z-scaling of
87         + gradient (doZscalePack) and
88         + control (doZscaleUnpack)
89    o pkg/mdsio/
90      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
91      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
92    
93    checkpoint57b_post
94    o simplify options in diagnostics_fill arguments (remove weird combinations)
95    o fix MNC coordinate variables so that they now contain per-face index
96      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
97      general, EXCH2 grids are only aligned to a "local" coordinate system
98    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
99    o Implement instantaneous output within pkg diagnostics:
100      setting a negative frequency in data.diagnostics produces
101     "snap-shot" output (as opposed to time-average if freq > 0)
102    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
103      NOTE: change ptracer diagnostics name: use 2 characters to work with
104            more than 9 tracers. Add also diagnostics of advect & diffus flux.
105    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
106      becomes the coordinate variable for the 'T' dimension
107    o add CF-style coordinate variables to MNC
108      - just a first cut:  numbers are meaningless on the cubesphere and
109        missing along the T axis but otherwise it works!
110    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
111    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
112    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
113      this is based directly on what the model compute, so that the content of
114      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
115    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
116    o clean up build options files for SunOS, in particular
117      - remove -traditional from xmakedepend
118      - change -xarch=v9 to -xarch=native for f77
119      - restore use of make (not gmake)
120      - add CC=gcc if using g77
121    o changes per discussion of AM, JMC, & EH3 today:
122      - move redundant "grid" variables out of "state" -- in preparation of
123        creating proper CF-style coordinate variables and in recognition
124        that any/all grid variables can be easily copied (eg. w/NCO) from
125        the grid files into any of the other NetCDF files
126      - *always* output grid variables with MDSIO (this will eventually be
127        changed)
128      - output MNC grid file if useMNC is true
129    o every instance of _END_MASTER() has been found and replaced with
130      _END_MASTER( myThid ) in order to satisfy certain picky Sun
131      preprocessors
132    o re-arrange diagnostics pkg initialisation:
133     - allow each package to extend the available diagnostics list
134     - add some checking and fix small problems (multi-threaded, ...)
135     - new S/R diagnostics_fill (replace fill_diagnostics):
136       look through the short list of active diag. (instead of the long list)
137       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
138    
139    checkpoint57a_post
140    o this set of changes restores TAMC compatibility
141      tested for global_ocean.90x40x15 adjoint on trough
142      (what a pain)
143    
144    checkpoint57a_pre
145    o some modifs in tools/build_options for sunos
146    o call ctrl_pack for ctrl at end for optimcycle=0
147    
148    checkpoint57
149    o add horizontal bi-harmonic viscosity for vertical velocity
150      - new parameter viscA4W (defaults to viscA4)
151      - affects only non-hydrostatic code
152      - to be done: no-slip lateral boundary conditions
153    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
154    o implement Implicit Vertical advection for pTracers
155    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
156      (implemented also for implicit vertical diffusion & advection)
157    o OBCS: extend application of tracer open boundary conditions
158      to a strip beyond the boundary of width Olx/Oly
159    o add call monitor to TAF set of required calls (flow directives)
160      and include in natl_box_adjoint
161    o untangle a few ifdefs related to cost, ctrl, autodiff
162      untangel a few ALLOW_ECCO_OPTIMIZATION
163    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
164      (theta2, salt2 in ecco_cost_weights)
165    
166    checkpoint56c_post
167    o OBCS as control variables
168      - update ctrl_ad_diff.list, obcs_ad_diff.list
169      - remove balance of obcs controls from default
170      - fix index bug nobcs in ctrl_init
171      - fix dummy fields filen in ctrl_pack
172      - add dummy weights for obcs
173    o lsopt: comment out fort.94 output
174    o optim:
175      - remove unnecessary header files
176      - adjusted namelists
177      - add xerbla.F to Makefile
178    o exf:
179      - multiple modifications of exf_check_range
180      - unit change in exf_init_runoff from [m/year] to [m/s]
181    o mdsio:
182      - i/o-vector change debugLevel from debLevA to debLevB
183    
184    checkpoint56b_post
185    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
186      is called from DO_THE_MODEL_IO
187      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
188      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
189      - clean up PTRACERS_WRITE_TIMEAVE a little
190    o add another verification experiment that tests both the cfc-pkg and
191      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
192      reactive tendencies treated inline with regular timestepping
193    o testreport previously did a lousy job of comparing small numbers, so
194      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
195      implemented in the little c-progam tmp_cmpnum.c which is embedded in
196      testreport.
197    o ptracers_monitor: bug fix for MPI
198    
199    checkpoint56a_post
200    o GCHEM: finish reorganizating the package
201      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
202        (introduces another 3D-array for each passive tracer, but only if
203        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
204        gchemTendency is not needed because the timestep is done separately)
205      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
206      - GCHEM is now---more or less cleanly---separate from PTRACERS
207      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
208        so clear to me how that should be done in a general way.
209    o CFC: improve formatting of output in CFC_ATMOS
210    o PTRACERS:
211      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
212        that ALL experiments with ptracers enable can be checked. This makes
213        GCHEM_MONITOR obsolete.
214      - include a runtime parameter PTRACERS_monitorFreq that defaults to
215        monitorFreq
216      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
217    o add PTRACERS (PTR0[1-5]) to testreport output
218    o exf_check_range:
219      * default changed to .TRUE.
220      * will check values for niter0 if debLevA, every timestep if debLevB
221      * STOP in exf_check_range if 'out of range'
222      * range chosen generous to allow for potential extema
223      TBD: a version with stricter range
224           permitted range would be runtime parameters
225    o GMredi:
226      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
227      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
228      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
229    o GCHEM:
230      - move call to GCHEM_FORCING_SEP, so that it is now called before
231        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
232      - introduced a useGCHEM runtime flag and applied it everywhere.
233      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
234        this flag is now only visible within GCHEM-pkg routines.
235      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
236        be replaced by a 3D array that is computed before thermodynamics; for
237        this, the tracer ID iTracer had to be included into the parameter list
238        of ptracers_forcing
239      - set up forward_step to call gchem_forcing, that will replace
240        gchem_forcing_int in ptracers_forcing
241      - cleaning up
242    o small cleaning of exch2: remove files that are also in eesupp/src
243    
244    checkpoint56
245    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
246    o mnc: cleanup "full" files--fixes out-of-memory problem
247    o ECCO-GODAE
248      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
249      * fully merged and updated from SIO code
250        windstress sign change affects
251        - exf_inscal_[u/v]stress
252        - sign of xx_tau[u/v] adjustments
253        - signs in cost_scat
254      * ctrl_get_gen: avoid update of tau[u/v] for first few days
255      * natl_box_adjoint updated and compressed
256      * 2-level checkpoint switch added
257        (tested in EXP. 1 of natl_box_adjoint)
258      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
259    o SVD
260      * first complete, non-hacked version for SVD calculations
261      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
262        performed via direct access files admtlm_vector.it????
263        (via ctrl_[un]pack)
264      * optimcycle is used for ARPACK iteration counter
265        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
266      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
267        and add linear transforms where necessary
268      * controls are initial/final SST, SSS (can be extended; need to check
269        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
270    o mdsio: filename info to both stderr, stdout
271    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
272      from sign change
273    
274    checkpoint55j_post
275    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
276      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
277    o add consistent build directories and .cvsignore files to verification
278    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
279    o make all subroutines 30 or less characters in length for certain older
280      compilers to work (a thorough search only turns up two routines in
281      pkg/ptracers)
282    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
283      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
284    
285    checkpoint55i_post
286    o change arrays for total vertical diffusivity (2.D if explicit,
287      3.D if implicit) ; each ptracer uses its own background value.
288    o added mnc/NetCDF output capability to ocn_compon_interf
289      - added bits to verification/cpl_aim+ocn so that it can run on
290        ITRDA and other clusters without the mpirun "-wd" option
291    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
292      configuration
293    o give MNC the ability to create additional files rather than
294      exceeding a specified file size limit "MNC_MAX_FILESIZE"
295      - the default is just less than 2GB which is a practical limit
296        on many systems
297    o Compute the non-local term using either KPP vertical diffusivity (=default)
298       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
299    
300    checkpoint55h_post
301    o add verification test "vermix"
302    o remove all the *_ioinc flags and replace with the single global
303      outputTypesInclusive flag
304    o allow to set a vertical profile of vertical diffusivity for T & S
305    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
306    o useMNC moved from data.mnc to data.pkg
307    
308    checkpoint55g_post
309    o Renaming carbon AD experiments to comply with testreport conventions
310    o Updating adjoint of Held-Suarez hs94.1x64x5
311    o Fixing directives for non-ECCO forward_step, after ECCO directives
312      have been fixed to avoid recomp. of do_oceanic_phys
313      Works well for global_ocean.90x40x15,
314      but recomp. issue remains for carbon
315    o Updating adjoint output for natl_box_adjoint after
316      pkg/ecco has been modified (see taga c55d_post)
317    
318    checkpoint55f_post
319    o rename to timeave_init_fixed
320    
321    checkpoint55e_post
322    o some delicate re-shuffle of store directives to avoid one
323      extra call of do_oceanic_physics
324      affects ecco_the_main_loop.F, do_oceanic_physics.F
325      checkpoint_lev1_directives.h
326    o NB: this may break global_ocean adjoint temporarily,
327      but it is clear how to fix it. Will do later, need this now.
328    
329    checkpoint55d_post
330    o ECCO specific cost function terms (up-to-date with 1x1 runs)
331    o ecco_cost_weights is modified to 1x1 runs
332    o modifs to allow observations to be read in as
333      single file or yearly files
334    o enable to read exf forcing fields as either
335      single file or yearly files (flag useExfYearlyFields)
336    checkpoint55d_pre
337    
338    o switch between 2-level and 3-level checkpointing
339    o add ability of MNC to write local and "partial" (eg. 2D slices where
340      the full 3D field is never actually stored) arrays to NetCDF files
341      with the correct (that is, the complete multi-dimensional) set of
342      array indicies
343      - used in mom_vecinv() to write the diagFreq output
344      - tested (demonstrated) in verification/aim.5l_cs
345    o further mnc-ification
346      - add verification/lab_sea to the list with mnc setups
347      - fix undefined mnc v-names in cd_code
348      - add kpp to mnc output (both snapshot and timeave)
349    o non-hydrostatic code
350      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
351        in calc_gw.F
352      - defaults to viscAh
353      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
354        friction or Leith) in non-hydrostatic mode, as long as there is
355        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
356    o pkg/cost
357      extend simple cost functions to treat time mean quantities
358      (T,U,V) via cost_accumulate_state from cost_tile
359    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
360        be 2 times larger than the minimum size the advection scheme requires.
361        now get a perfect conservation of salt in advect_cs test-exp (updated)
362    o GGL90 (Gaspar's TKE mixed layer)
363      - add horizontal diffusion of TKE, requires exchanges in
364        do_fields_blocking_exchanges, horizontal diffusivity is zero by
365        default. In OPA there is no horizontal diffusion of TKE but the
366        mixing coefficients are computed from a horizontal average of TKE of
367        6 points or so. I think that diffusion has a little more physical
368        justification.
369      - clean up ggl90_calc in the hope of reducing memory usage (this hope
370        was in vain)
371      - mask tke-variable in ggl90_init
372    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
373    o fix biharmonic diffusion on CS-grid.
374    o more obcs stuff
375      - added obcs_external_fields_load as an alternative to the EXF-pkg option
376        for reading boundary values. This routine is called from
377        obcs_prescribe_read
378      - updated obcs_check
379      - changed sponge layer relaxation parameter units for days to seconds
380      - turned off sponge layer by default
381      - changed argument list of OBCS_CALC to myTime+deltaTclock
382      - fixed about 35 bugs in obcs_external_fields_load
383    
384    checkpoint55c_post
385    o obcs stuff
386      - new runtime flags useOBCSprescribe, useOBCSbalance
387      - re-arranged obcs_calc
388      - moved exf_getobcs to obcs_prescibe_read
389        obcs_prescibe_read is called after ORLANSKI stuff
390        and independent of it (executable can contain all).
391      - updated obcs_check
392      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
393        These may be necessary only if tangential velocities are
394        prescribed at OB, not sure, needs testing.
395    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
396      which simplifies the calls and passes the ifc check-bounds test
397    
398    checkpoint55b_post
399    o add a 2D scalar, Z location, exchange_2 routine.
400    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
401      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
402      affects advect_cs results (for the wrong reason): update output.txt
403    o use a more standard discretization for biharmonic viscosity ;
404     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
405      affects results of dome set-up: update output.txt
406    o fix gad_advection.F (CubedSphere part), back to version 1.23
407    o fix bug in mom_vi_del2uv.F (CubedSphere part).
408    
409    checkpoint55a_post
410    o merged code to
411      * prescribe/read time-dependent open boundaries
412        (works in conjunction with exf, cal)
413      * sponge layer code for open boundaries
414      * each boundary N/S/E/W now has its own CPP option
415        (healthy for the adjoint)
416    
417    checkpoint55
418    o up-to-date adjoint of previous breaks
419      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
420      - global_ocean_ebm: adjoint still needs fix (TLM ok)
421      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
422      - carbon: * remove tr1-related adjoint verification
423                * add ptracer as control variable
424    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
425      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
426    
427    checkpoint54f_post
428    o in verification/carbin/ remove experiment related to
429      ALLOW_PASSIVE_TRACER (array tr1 etc)
430      code_ad/ input_ad/ results_ad
431    
432    o add two new packages
433      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
434        + subject to optimization (memory)
435      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
436        + subject to reordering (many GOTOs in the original code)
437        + so far opps is called for every (i,j) point, and then operates in
438          the vertical; one may want to reorder the scheme in order operate in
439          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
440          fields)
441    o overhaul of IO so that we now have flags for MDSIO and/or MNC
442      - all verification tests compile and run with linux_ia32_g77
443      - defaults are compatible with current input files--nothing
444        should change if you were not previously using MNC
445      - MNC output has been added in numerous places (eg. timeave)
446        but there are still a few writes not yet do-able with MNC
447        (this is in progress)
448      - flags now allow for either/or/both use of MDSIO and MNC and
449        documentation will soon follow
450      - numerous small formatting cleanups for ProTeX
451    o add version info (via BUILD_INFO.h) to MNC and stdout
452    
453    checkpoint54e_post
454    o add two new packages
455      - pp81 (Packanowski and Philander, 1981), Richardson number and
456        stratification dependent mixing
457      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
458      - these scheme operate in a similar manner as KPP (without ghat, of
459        course), however there is only one diffusivity that is used for both
460        temperature and salinity (and passive tracers)ç
461    o add offline package
462    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
463      provided by Stephanie Dutkiewicz
464    o genmake2: add ability to search for C compilers and cleanup test output
465      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
466    
467    checkpoint54d_post
468    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
469    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
470      leading to additional shift by 5 days each year of integration
471       (i.e. leading to considerable offset over the years)
472    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
473    o start with no AB and no initial filtering (staggerTimeStep):
474      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
475    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
476      (external loading & cpl import/export stay in forward_step.F)
477    o update coupling interface to work with new staggerTimeStep
478    o change MDSIO ptracers_pickup.
479    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
480    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
481    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
482    
483    checkpoint54c_post
484    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
485      this affects (truncation error) output.txt of test-exp:
486       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
487    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
488    o change Qnet to always be the net heat flux, (+upward).
489      affects (truncation error) output of natl_box exp.: updated
490    o define the max number of passive tracers in PTRACERS_SIZE.h
491    o start to test mnc routinely in exp0
492    o add sea-ice loading (sIceLoad) as a new forcing field.
493    
494    checkpoint54b_post
495    o add testreport "-j JOBS" option for parallel builds (tested and pretty
496       impressive on Altix and Opteron systems)
497    o diagnostics can now write NetCDF files through the mnc package
498    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
499    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
500    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
501      affects (truncation error) output of lab_sea & natl_box exp.: updated
502    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
503    
504    checkpoint54a_post
505    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
506    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
507    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
508    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
509      + internal_wave (shift in writing cg2d_ini_res)
510    checkpoint54a_pre
511    
512    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
513      - modified verification/lab_sea and natl_box_adjoint accordingly
514    
515    checkpoint54
516    checkpoint53g_post
517    o prepare splitting of thermodynamics: store convect.counter in common block
518    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
519      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
520    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
521    o new parameter "nShapS": allow to treat differently S from T (nShapT)
522    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
523    o restore adjointability
524    
525    checkpoint53f_post
526    o modifications that affect AIM experiment results (update output.txt):
527      - no advection of S at top interface Nr (pkg/generic_advdiff)
528      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
529    o AIM pkg:
530      - include stability function into surf.Flux derivative relative to Tsurf
531      - calculate clear-sky radiation & surface temp. change (for diagnostics)
532    
533    checkpoint53e_post
534    o merged cylindrical coord configuration
535    o added rotating_tank experiment
536    checkpoint53e_pre
537    
538    checkpoint53d_post
539    o faulks upgraded: re-generate output.txt that have changed:
540       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
541    o Added Bryan and Lewis, 1979, vertical diffusivity profile
542    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
543    o added Sadourny discretization of Coriolis
544      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
545      - re-enabled use of omega3 (useAbsVorticity)
546    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
547      vector-invariant equations
548      - note: does *NOT* yet use same variable visc. for no-slip BC's.
549    o recoded the lateral boundary conditions for non-hydrostatic w, this time
550      hopefully without new bugs
551      - still to do: biharmonic friction for non-hydrostatic w
552    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
553    o regenerated output for global_ocean_ebm (using -ieee)
554    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
555      of mom_common/
556      - simple re-arrangement of instructions within computing loop
557    checkpoint53d_pre
558    
559    checkpoint53c_post
560    o new version of coupler for AIM+thSIce and Ocean models
561     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
562     - land: change Evaporation of snow
563     - aim with thSIce: fix bug in snow-precip.
564    o changes to calc_gw.F
565     - bug fix for w^2 term near the bottom boundary
566     - (hopefully) improve the lateral slip boundary condtions for use with
567        partial/looped cells
568      - because the bug fix changes two verification experiments anyway (exp5
569        and plume on slope), change the lateral boundary condition from half slip
570        to the value of no_slip_sides
571    o ebm package wasnt quite up to the parallel task. Fixed that.
572    o Adjoint of EBM package + verification
573      * TLM OK
574      * ADM not sufficient accuracy yet (needs further testing)
575    
576    checkpoint53b_post
577    o Commiting new energy balance model to repository
578      * package is pkg/ebm
579      * verif. is verification/global_ocean_ebm
580      * references are in ebm_driver.F
581    C      * X. Wang, P. Stone and J. Marotzke, 1999:
582    C        Global thermohaline circulation. Part I:
583    C        Sensitivity to atmospheric moisture transport.

585    C      * X. Wang, P. Stone and J. Marotzke, 1999:
586    C        Global thermohaline circulation. Part II:
587    C        Sensitivity with interactive transport.

589    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
590    C        Destabilization of the thermohaline circulation
591    C        by atmospheric eddy transports.
592    C        J. Climate 7(12), 1870-1882
593    o Will need long integration testing.
594    checkpoint53b_pre
595    
596    o created pkg/mom_common in preparation for variable viscosity code
597    o renamed and split ini_mnc_io
598    o pkg/land: only liquid water can diffuse or run-off
599    o AIM using land: soil wetness availability account for snow
600    o added printMapIncludesZeros to EEPARMS namelist
601    
602    checkpoint53a_post
603    o restore TAMC compatiility for exf_constants.h
604      (no usage of _d in .h)
605    o Additional storing in KPP in an attempt to fix
606      TAMC problem with adjoint of KPP code.
607      (no success...)
608      Identical code works fine with TAF.
609    o Fixed verification/natl_box_adjoint experiments.
610      Initial conditions for Experiments 4 and 5 are now
611      set to "SEAICE_initialHEFF=0", which is more reasonable,
612      and hence gives results closer to that of Experiment 2.
613      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
614    
615    checkpoint53
616    o stable checkpoint with up to date adjoint
617      TLM tests only run for 1st grdchk at the moment. Its unclear if
618      this is a code problem or a problem with resetting code for g_
619      variables that is being autogenerated wrong.
620      Otherwise:
621       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
622       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
623         are both still in chaos following their security messes.
624    
625    checkpoint52n_post
626    o various build (mostly genmake2) changes including:
627      - ability to build/run more easily within Cygwin and MacOS X
628      - more complicated Makefiles with a stronger dependence on Gnu Make
629    o pkg/seaice modifications
630      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
631        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
632        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
633      - changed proxy for geostrophic velocity and updated
634        verification/lab_sea/results/* accordingly
635      - removed ADI dynamic solver from pkg/seaice
636      - replaced all occurrences of 1/CSTICE or 1/CSUICE
637        they caused a segmentation fault under certain circumstances
638      - removed unused field WATR
639    o bug fix in exf-package:
640      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
641         now reflect that.
642    o small fixes in the cal-package:
643      - set reference date to first of January for the 'model'-calendar
644      - failing of cal_CheckDate in cal_FullDate now actually results in a
645        warning
646    o small modifications in exf-package to increase flexibility:
647      - change climtempfreeze from a constant to a runtime parameter that
648        is specified in data.exf_clim (default = -1.9)
649      - introduce runtime parameter windstressmax (default = 2.0) that is
650        specified in data.exf
651    o fix in pkg/thsice:
652      - update Evap (Tsf changes) to be consistent with Latent heat flux
653      - maintain snow precipitation unchanged (even if Tsf >=0).
654     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
655    
656    checkpoint52m_post
657    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
658      this does not change any of the results, because myIter=0 in swfrac always
659      lead to jwtype=2 (the default anyway), but the call makes little sense
660      as a default
661    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
662    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
663      atmospheric model (AIM) to use it ; add a "slab ocean" component.
664    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
665    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
666    o extending useSingleCpuIO option to work with new exch2 I/O format
667      - old-style, missing-tile I/O is still accessible by defining CPP
668        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
669    o monitor package can write to NetCDF files and/or STDOUT
670    o fix re-definition bug in MNC_GRID_INIT_ALL()
671    o doc/api_reference added
672      - a framework for building an API Reference Manual using all
673        the "protex" comments embedded in the code
674      - see pkg/generic_advdiff, pkg/mnc for examples
675    o MNC:
676      - make myThid the last argument for all subroutines
677      - new default for the grid files: NO halos
678      - add useMNC and other run-time flags
679      - separate per-file-group handling of the unlimited dimension
680      - early initialization of MNC w/ flags read at the eeboot stage
681        and lookup tables set in initialize_fixed
682      - write all MNC output to a freshly-created directory
683    o thermodynamics sea-ice (thsice) is now tested with testreport.
684    o test exp. advect_cs: use the standard cs32 grid ; update output.
685    o Added functionality to grdchk:
686      pick global i,j,k position (or nearest wet) where to perform check.
687    
688    checkpoint52l_post
689    o new land formulation:
690      a) use ground enthalpy as prognostic variable to ensure exact
691         energy conservation.
692      b) account for water temperature and for latent heat of freezing
693         in all processes (rain, run-off, ground storage)
694      c) compute surface and ground temperature implicitly.
695    o aim_v23 modification for new land model:
696      a) Treat separately land / ocean / sea-ice surface fluxes
697         to allow implicit computation of land & sea-ice surface temp.
698      b) add snow precipitation.
699    checkpoint52l_pre
700    
701    o fix problem (when 1 tile is empty) in min/max monitor.
702    o fix bug in timeAve (u,vZetatave in common block)
703    o no restoring terms under ice for pkg/seaice
704    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
705    o bug fix for pkg/seaice pickups
706    o change MNC call locations and add coordinate attributes
707    o mask vorticity at the corner ; affects global_ocean.cs output
708    o fix ini_curvilinear_grid ; test CS experiments with mpi
709    o aim.5l_cs: modify sea-ice fraction input file ; update output
710    o exf: Adding simple range check routine for exf fields after read
711    
712    checkpoint52k_post
713    o removed top-level directory "diags"
714      - we migrated these functions to pkg/timeave a long time ago
715    o fixed bug introduced in pkg/monitor
716    o accuracy ctrlprec = 32 insuffient for gradient checks using
717      averaged fields (I/O via cost_averages)
718      -> use ctrl.h in active_file*.F to control I/O precision.
719    o paramter list of CALL ADTHE_MAIN_LOOP
720    o added initial do_the_model_io to ecco
721    o set all ...Freq to zero after cost_final
722      taveFreq, dumpFreq, pChkptFreq
723    o MAIN and ECCO differentiability restored
724    
725    checkpoint52j_post
726    o fix nchklev in tamc.h for global_ocean...
727    o Bringing flow and store directives up-to-date
728    o Really weird thing!
729      call do_the_model_io from the_main_loop with parameters
730      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
731      TAF places a faulty re-call of initialise_varia
732      after cost_final call which should not be there!
733    checkpoint52j_pre
734    
735    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
736      error messages
737    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
738    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
739      debug output
740    o modfied mdsio_writefield.F to handle non-global files under exch2
741    o update AIM Cubed-Sphere exp (aim.5l_cs):
742      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
743    o update AIM Equatorial Channel exp:
744      use standard aim_v23 pkg and change the SST fields to be more realistic.
745    o globalFile now works with exch2
746    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
747      mon_vort3.F to make exch2 friendly with >1 tile per cube face
748    o limit timeave output for hi-res integrations
749    
750    checkpoint52i_post
751    o removed CPP_EEOPTIONS.h from verification/*/code
752    o updated the tiling for global_ocean_pressure
753    checkpoint52i_pre
754    
755    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
756      the old pkg/aim).
757    
758    checkpoint52h_pre
759    o shortened offending lines in exch2_send_rx?.template
760    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
761  o genmake2: add build & execute test for NetCDF code  o genmake2: add build & execute test for NetCDF code
762  o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed  o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
763    old grid files, moved CPP_EEMACROS.h to pkg/exch2    old grid files, moved CPP_EEMACROS.h to pkg/exch2
764  o added useSingleCPUIO flag to monitor.F and mon_out.F  o added useSingleCPUIO flag to monitor.F and mon_out.F
765    o added temporary hack for sea-ice dynamics on the cube:
766      metric terms are ignored and it is assumed that
767      there is no sea-ice on cube faces 1, 2, 4, and 5.
