3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
7    o mnc: cleanup "full" files--fixes out-of-memory problem
8    
9    checkpoint55j_post
10    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
11      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
12    o add consistent build directories and .cvsignore files to verification
13    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
14    o make all subroutines 30 or less characters in length for certain older
15      compilers to work (a thorough search only turns up two routines in
16      pkg/ptracers)
17    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
18      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
19    
20    checkpoint55i_post
21    o change arrays for total vertical diffusivity (2.D if explicit,
22      3.D if implicit) ; each ptracer uses its own background value.
23    o added mnc/NetCDF output capability to ocn_compon_interf
24      - added bits to verification/cpl_aim+ocn so that it can run on
25        ITRDA and other clusters without the mpirun "-wd" option
26    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
27      configuration
28    o give MNC the ability to create additional files rather than
29      exceeding a specified file size limit "MNC_MAX_FILESIZE"
30      - the default is just less than 2GB which is a practical limit
31        on many systems
32    o Compute the non-local term using either KPP vertical diffusivity (=default)
33       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
34    
35    checkpoint55h_post
36    o add verification test "vermix"
37    o remove all the *_ioinc flags and replace with the single global
38      outputTypesInclusive flag
39    o allow to set a vertical profile of vertical diffusivity for T & S
40    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
41    o useMNC moved from data.mnc to data.pkg
42    
43    checkpoint55g_post
44    o Renaming carbon AD experiments to comply with testreport conventions
45    o Updating adjoint of Held-Suarez hs94.1x64x5
46    o Fixing directives for non-ECCO forward_step, after ECCO directives
47      have been fixed to avoid recomp. of do_oceanic_phys
48      Works well for global_ocean.90x40x15,
49      but recomp. issue remains for carbon
50    o Updating adjoint output for natl_box_adjoint after
51      pkg/ecco has been modified (see taga c55d_post)
52    
53    checkpoint55f_post
54    o rename to timeave_init_fixed
55    
56    checkpoint55e_post
57    o some delicate re-shuffle of store directives to avoid one
58      extra call of do_oceanic_physics
59      affects ecco_the_main_loop.F, do_oceanic_physics.F
60      checkpoint_lev1_directives.h
61    o NB: this may break global_ocean adjoint temporarily,
62      but it is clear how to fix it. Will do later, need this now.
63    
64    checkpoint55d_post
65    o ECCO specific cost function terms (up-to-date with 1x1 runs)
66    o ecco_cost_weights is modified to 1x1 runs
67    o modifs to allow observations to be read in as
68      single file or yearly files
69    o enable to read exf forcing fields as either
70      single file or yearly files (flag useExfYearlyFields)
71    checkpoint55d_pre
72    
73    o switch between 2-level and 3-level checkpointing
74    o add ability of MNC to write local and "partial" (eg. 2D slices where
75      the full 3D field is never actually stored) arrays to NetCDF files
76      with the correct (that is, the complete multi-dimensional) set of
77      array indicies
78      - used in mom_vecinv() to write the diagFreq output
79      - tested (demonstrated) in verification/aim.5l_cs
80    o further mnc-ification
81      - add verification/lab_sea to the list with mnc setups
82      - fix undefined mnc v-names in cd_code
83      - add kpp to mnc output (both snapshot and timeave)
84    o non-hydrostatic code
85      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
86        in calc_gw.F
87      - defaults to viscAh
88      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
89        friction or Leith) in non-hydrostatic mode, as long as there is
90        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
91    o pkg/cost
92      extend simple cost functions to treat time mean quantities
93      (T,U,V) via cost_accumulate_state from cost_tile
94    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
95        be 2 times larger than the minimum size the advection scheme requires.
96        now get a perfect conservation of salt in advect_cs test-exp (updated)
97    o GGL90 (Gaspar's TKE mixed layer)
98      - add horizontal diffusion of TKE, requires exchanges in
99        do_fields_blocking_exchanges, horizontal diffusivity is zero by
100        default. In OPA there is no horizontal diffusion of TKE but the
101        mixing coefficients are computed from a horizontal average of TKE of
102        6 points or so. I think that diffusion has a little more physical
103        justification.
104      - clean up ggl90_calc in the hope of reducing memory usage (this hope
105        was in vain)
106      - mask tke-variable in ggl90_init
107    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
108    o fix biharmonic diffusion on CS-grid.
109    o more obcs stuff
110      - added obcs_external_fields_load as an alternative to the EXF-pkg option
111        for reading boundary values. This routine is called from
112        obcs_prescribe_read
113      - updated obcs_check
114      - changed sponge layer relaxation parameter units for days to seconds
115      - turned off sponge layer by default
116      - changed argument list of OBCS_CALC to myTime+deltaTclock
117      - fixed about 35 bugs in obcs_external_fields_load
118    
119    checkpoint55c_post
120    o obcs stuff
121      - new runtime flags useOBCSprescribe, useOBCSbalance
122      - re-arranged obcs_calc
123      - moved exf_getobcs to obcs_prescibe_read
124        obcs_prescibe_read is called after ORLANSKI stuff
125        and independent of it (executable can contain all).
126      - updated obcs_check
127      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
128        These may be necessary only if tangential velocities are
129        prescribed at OB, not sure, needs testing.
130    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
131      which simplifies the calls and passes the ifc check-bounds test
132    
133    checkpoint55b_post
134    o add a 2D scalar, Z location, exchange_2 routine.
135    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
136      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
137      affects advect_cs results (for the wrong reason): update output.txt
138    o use a more standard discretization for biharmonic viscosity ;
139     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
140      affects results of dome set-up: update output.txt
141    o fix gad_advection.F (CubedSphere part), back to version 1.23
142    o fix bug in mom_vi_del2uv.F (CubedSphere part).
143    
144    checkpoint55a_post
145    o merged code to
146      * prescribe/read time-dependent open boundaries
147        (works in conjunction with exf, cal)
148      * sponge layer code for open boundaries
149      * each boundary N/S/E/W now has its own CPP option
150        (healthy for the adjoint)
151    
152    checkpoint55
153    o up-to-date adjoint of previous breaks
154      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
155      - global_ocean_ebm: adjoint still needs fix (TLM ok)
156      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
157      - carbon: * remove tr1-related adjoint verification
158                * add ptracer as control variable
159    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
160      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
161    
162    checkpoint54f_post
163    o in verification/carbin/ remove experiment related to
164      ALLOW_PASSIVE_TRACER (array tr1 etc)
165      code_ad/ input_ad/ results_ad
166    
167    o add two new packages
168      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
169        + subject to optimization (memory)
170      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
171        + subject to reordering (many GOTOs in the original code)
172        + so far opps is called for every (i,j) point, and then operates in
173          the vertical; one may want to reorder the scheme in order operate in
174          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
175          fields)
176    o overhaul of IO so that we now have flags for MDSIO and/or MNC
177      - all verification tests compile and run with linux_ia32_g77
178      - defaults are compatible with current input files--nothing
179        should change if you were not previously using MNC
180      - MNC output has been added in numerous places (eg. timeave)
181        but there are still a few writes not yet do-able with MNC
182        (this is in progress)
183      - flags now allow for either/or/both use of MDSIO and MNC and
184        documentation will soon follow
185      - numerous small formatting cleanups for ProTeX
186    o add version info (via BUILD_INFO.h) to MNC and stdout
187    
188    checkpoint54e_post
189    o add two new packages
190      - pp81 (Packanowski and Philander, 1981), Richardson number and
191        stratification dependent mixing
192      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
193      - these scheme operate in a similar manner as KPP (without ghat, of
194        course), however there is only one diffusivity that is used for both
195        temperature and salinity (and passive tracers)ç
196    o add offline package
197    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
198      provided by Stephanie Dutkiewicz
199    o genmake2: add ability to search for C compilers and cleanup test output
200      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
201    
202    checkpoint54d_post
203    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
204    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
205      leading to additional shift by 5 days each year of integration
206       (i.e. leading to considerable offset over the years)
207    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
208    o start with no AB and no initial filtering (staggerTimeStep):
209      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
210    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
211      (external loading & cpl import/export stay in forward_step.F)
212    o update coupling interface to work with new staggerTimeStep
213    o change MDSIO ptracers_pickup.
214    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
215    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
216    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
217    
218    checkpoint54c_post
219    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
220      this affects (truncation error) output.txt of test-exp:
221       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
222    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
223    o change Qnet to always be the net heat flux, (+upward).
224      affects (truncation error) output of natl_box exp.: updated
225    o define the max number of passive tracers in PTRACERS_SIZE.h
226    o start to test mnc routinely in exp0
227    o add sea-ice loading (sIceLoad) as a new forcing field.
228    
229    checkpoint54b_post
230    o add testreport "-j JOBS" option for parallel builds (tested and pretty
231       impressive on Altix and Opteron systems)
232    o diagnostics can now write NetCDF files through the mnc package
233    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
234    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
235    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
236      affects (truncation error) output of lab_sea & natl_box exp.: updated
237    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
238    
239    checkpoint54a_post
240    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
241    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
242    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
243    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
244      + internal_wave (shift in writing cg2d_ini_res)
245    checkpoint54a_pre
246    
247    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
248      - modified verification/lab_sea and natl_box_adjoint accordingly
249    
250    checkpoint54
251    checkpoint53g_post
252    o prepare splitting of thermodynamics: store convect.counter in common block
253    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
254      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
255    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
256    o new parameter "nShapS": allow to treat differently S from T (nShapT)
257    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
258    o restore adjointability
259    
260    checkpoint53f_post
261    o modifications that affect AIM experiment results (update output.txt):
262      - no advection of S at top interface Nr (pkg/generic_advdiff)
263      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
264    o AIM pkg:
265      - include stability function into surf.Flux derivative relative to Tsurf
266      - calculate clear-sky radiation & surface temp. change (for diagnostics)
267    
268    checkpoint53e_post
269    o merged cylindrical coord configuration
270    o added rotating_tank experiment
271    checkpoint53e_pre
272    
273    checkpoint53d_post
274    o faulks upgraded: re-generate output.txt that have changed:
275       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
276    o Added Bryan and Lewis, 1979, vertical diffusivity profile
277    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
278    o added Sadourny discretization of Coriolis
279      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
280      - re-enabled use of omega3 (useAbsVorticity)
281    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
282      vector-invariant equations
283      - note: does *NOT* yet use same variable visc. for no-slip BC's.
284    o recoded the lateral boundary conditions for non-hydrostatic w, this time
285      hopefully without new bugs
286      - still to do: biharmonic friction for non-hydrostatic w
287    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
288    o regenerated output for global_ocean_ebm (using -ieee)
289    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
290      of mom_common/
291      - simple re-arrangement of instructions within computing loop
292    checkpoint53d_pre
293    
294    checkpoint53c_post
295    o new version of coupler for AIM+thSIce and Ocean models
296     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
297     - land: change Evaporation of snow
298     - aim with thSIce: fix bug in snow-precip.
299    o changes to calc_gw.F
300     - bug fix for w^2 term near the bottom boundary
301     - (hopefully) improve the lateral slip boundary condtions for use with
302        partial/looped cells
303      - because the bug fix changes two verification experiments anyway (exp5
304        and plume on slope), change the lateral boundary condition from half slip
305        to the value of no_slip_sides
306    o ebm package wasnt quite up to the parallel task. Fixed that.
307    o Adjoint of EBM package + verification
308      * TLM OK
309      * ADM not sufficient accuracy yet (needs further testing)
310    
311    checkpoint53b_post
312    o Commiting new energy balance model to repository
313      * package is pkg/ebm
314      * verif. is verification/global_ocean_ebm
315      * references are in ebm_driver.F
316    C      * X. Wang, P. Stone and J. Marotzke, 1999:
317    C        Global thermohaline circulation. Part I:
318    C        Sensitivity to atmospheric moisture transport.
319    C        J. Climate 12(1), 71-82
320    C      * X. Wang, P. Stone and J. Marotzke, 1999:
321    C        Global thermohaline circulation. Part II:
322    C        Sensitivity with interactive transport.
323    C        J. Climate 12(1), 83-91
324    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
325    C        Destabilization of the thermohaline circulation
326    C        by atmospheric eddy transports.
327    C        J. Climate 7(12), 1870-1882
328    o Will need long integration testing.
329    checkpoint53b_pre
330    
331    o created pkg/mom_common in preparation for variable viscosity code
332    o renamed and split ini_mnc_io
333    o pkg/land: only liquid water can diffuse or run-off
334    o AIM using land: soil wetness availability account for snow
335    o added printMapIncludesZeros to EEPARMS namelist
336    
337    checkpoint53a_post
338    o restore TAMC compatiility for exf_constants.h
339      (no usage of _d in .h)
340    o Additional storing in KPP in an attempt to fix
341      TAMC problem with adjoint of KPP code.
342      (no success...)
343      Identical code works fine with TAF.
344    o Fixed verification/natl_box_adjoint experiments.
345      Initial conditions for Experiments 4 and 5 are now
346      set to "SEAICE_initialHEFF=0", which is more reasonable,
347      and hence gives results closer to that of Experiment 2.
348      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
349    
350    checkpoint53
351    o stable checkpoint with up to date adjoint
352      TLM tests only run for 1st grdchk at the moment. Its unclear if
353      this is a code problem or a problem with resetting code for g_
354      variables that is being autogenerated wrong.
355      Otherwise:
356       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
357       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
358         are both still in chaos following their security messes.
359    
360    checkpoint52n_post
361    o various build (mostly genmake2) changes including:
362      - ability to build/run more easily within Cygwin and MacOS X
363      - more complicated Makefiles with a stronger dependence on Gnu Make
364    o pkg/seaice modifications
365      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
366        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
367        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
368      - changed proxy for geostrophic velocity and updated
369        verification/lab_sea/results/* accordingly
370      - removed ADI dynamic solver from pkg/seaice
371      - replaced all occurrences of 1/CSTICE or 1/CSUICE
372        they caused a segmentation fault under certain circumstances
373      - removed unused field WATR
374    o bug fix in exf-package:
375      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
376         now reflect that.
377    o small fixes in the cal-package:
378      - set reference date to first of January for the 'model'-calendar
379      - failing of cal_CheckDate in cal_FullDate now actually results in a
380        warning
381    o small modifications in exf-package to increase flexibility:
382      - change climtempfreeze from a constant to a runtime parameter that
383        is specified in data.exf_clim (default = -1.9)
384      - introduce runtime parameter windstressmax (default = 2.0) that is
385        specified in data.exf
386    o fix in pkg/thsice:
387      - update Evap (Tsf changes) to be consistent with Latent heat flux
388      - maintain snow precipitation unchanged (even if Tsf >=0).
389     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
390    
391    checkpoint52m_post
392    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
393      this does not change any of the results, because myIter=0 in swfrac always
394      lead to jwtype=2 (the default anyway), but the call makes little sense
395      as a default
396    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
397    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow

403        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
404    o monitor package can write to NetCDF files and/or STDOUT
405    o fix re-definition bug in MNC_GRID_INIT_ALL()
406    o doc/api_reference added
407      - a framework for building an API Reference Manual using all
408        the "protex" comments embedded in the code
409      - see pkg/generic_advdiff, pkg/mnc for examples
410    o MNC:
411      - make myThid the last argument for all subroutines
412      - new default for the grid files: NO halos
413      - add useMNC and other run-time flags
414      - separate per-file-group handling of the unlimited dimension
415      - early initialization of MNC w/ flags read at the eeboot stage
416        and lookup tables set in initialize_fixed
417      - write all MNC output to a freshly-created directory
418    o thermodynamics sea-ice (thsice) is now tested with testreport.
419    o test exp. advect_cs: use the standard cs32 grid ; update output.
420    o Added functionality to grdchk:
421      pick global i,j,k position (or nearest wet) where to perform check.
422    
423    checkpoint52l_post
424    o new land formulation:
425      a) use ground enthalpy as prognostic variable to ensure exact
426         energy conservation.
427      b) account for water temperature and for latent heat of freezing
428         in all processes (rain, run-off, ground storage)
429      c) compute surface and ground temperature implicitly.
430    o aim_v23 modification for new land model:
431      a) Treat separately land / ocean / sea-ice surface fluxes
432         to allow implicit computation of land & sea-ice surface temp.
433      b) add snow precipitation.
434    checkpoint52l_pre
435    
436    o fix problem (when 1 tile is empty) in min/max monitor.

445    o exf: Adding simple range check routine for exf fields after read
446    
447    checkpoint52k_post
448    o removed top-level directory "diags"
449      - we migrated these functions to pkg/timeave a long time ago
450    o fixed bug introduced in pkg/monitor
451    o accuracy ctrlprec = 32 insuffient for gradient checks using
452      averaged fields (I/O via cost_averages)
453      -> use ctrl.h in active_file*.F to control I/O precision.
454    o paramter list of CALL ADTHE_MAIN_LOOP
455    o added initial do_the_model_io to ecco
456    o set all ...Freq to zero after cost_final
457      taveFreq, dumpFreq, pChkptFreq
458    o MAIN and ECCO differentiability restored
459    
460    checkpoint52j_post
461    o fix nchklev in tamc.h for global_ocean...
462    o Bringing flow and store directives up-to-date
463    o Really weird thing!
464      call do_the_model_io from the_main_loop with parameters
465      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
466      TAF places a faulty re-call of initialise_varia
467      after cost_final call which should not be there!
468    checkpoint52j_pre
469    
470    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
471      error messages
472    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
473    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
474      debug output

477      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
478    o update AIM Equatorial Channel exp:
479      use standard aim_v23 pkg and change the SST fields to be more realistic.
480    o globalFile now works with exch2
481    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
482      mon_vort3.F to make exch2 friendly with >1 tile per cube face
483    o limit timeave output for hi-res integrations
484    
485    checkpoint52i_post

487    o updated the tiling for global_ocean_pressure
488    checkpoint52i_pre
489    
490    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
491      the old pkg/aim).
492    
493    checkpoint52h_pre
494    o shortened offending lines in exch2_send_rx?.template
495    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
496    o genmake2: add build & execute test for NetCDF code

498      old grid files, moved CPP_EEMACROS.h to pkg/exch2
499    o added useSingleCPUIO flag to monitor.F and mon_out.F
500    o added temporary hack for sea-ice dynamics on the cube:
501      metric terms are ignored and it is assumed that
502      there is no sea-ice on cube faces 1, 2, 4, and 5.
503    
504    checkpoint52f_post
505    o added exch2 cube routines to pkg/exch2
506    o modified hs94.cs-32x32x5 to use it
507    o added new grid files to hs94.cs-32x32x5
508    checkpoint52f_pre
509    
510    checkpoint52e_post
511    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
512      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
513    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
514      to work with implicit vertical advection and AB ;
515    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
516    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
517     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
518    checkpoint52e_pre
519    
520    o fix bug in impldiff when Nr=1 or Nr=2.
521    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
522    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
523    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
524      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
525    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
526    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
527    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
528    
529    checkpoint52d_post
530    o re-tiled many expts to allow comparison in multi-processor mode
531      - updated output accordingly
532      - changed hs94.128x64x5 to use intial T from file rather than use the
533        random number generator
534    o add infrastructure in model routines for fizhi and gridalt packages
535    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
536    o changes to permit hi-res, cubed-sphere, configuration
537      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
538      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
539      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
540        of surface winds for the cube
541      (A verification experiment, based on global_ocean.cs32x15, but with
542       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
543       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
544       complete with example surface forcing files and matlab scripts to look
545       at the output and compare it with that of global_ocean.cs32x15.)
546    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
547       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
548       to conform to the common rule.
549    o check-in the first version of the coupler + interfaces for multi-components
550       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
551       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
552       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
553       - ocean and atmos. share the same horizontal grid (no interpolation).
554       - exchanges between component and coupler is done in forward_step
555    o new verification experiment, cpl_aim+ocn:
556       coupled ocean - AIM atmosphere on cs32 grid.
557    
558    checkpoint52d_pre
559    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
560    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
561    
562    checkpoint52c_post
563    o Fixing OPTIONS files for use of exf:
564      - ALLOW_ECCO not needed
565      - ECCO_CPPOPTIONS.h should not be included from
566        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
567        as has been the case in the past
568      - All cal/exf related options are currently set in
569        single header file. Should remain so until we
570        agree on a consistent new policy.
571    o Removed all CPP options for cal package.
572      cal has no more CPP options.
573    o modified STOREs in GAD_ADVECTION
574    o corrected key comp. for passkey
575    
576    checkpoint52b_post
577    o new version: "thsice" of thermodynamic sea-ice pkg:
578     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
579     - modify fluxes but do not change theta directly;
580     - light cleaning of bulk_force pkg (still needed with thsice).
581     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
582       + output_thsice.txt to test thsice & bulk_force pkgs.
583    o put back grid & coriolis monitor output.
584    checkpoint52b_pre
585    
586    o call "do_the_model_io" at the beginning (=> dump initial state)
587    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
588    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
589      (need info on NUMBER_OF_PTRACERS)
590    o missing PTRACERS headers in some routines
591    o default tamc.h in pkg/autodiff supposed to crash
592      to ensure proper customization
593    
594    checkpoint52a_post
595    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
596      - moved surfaceTendencyTice from pkg/seaice to main code
597      - subroutine FREEZE_SURFACE now limits only surface temperature
598        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
599        => new output.txt for global_ocean.cs32x15 & global_with_exf
600      - keep the old version of FREEZE for backward compatibility;
601        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
602      - corresponding modifs for TAF directives
603    o added surface flux output variables to TIMEAVE_STATVARS
604    o time-averaged output for pkg/ptracers
605    o fix problem with ECCO-related divided adjoint

610    o some bug fixes for #undef REAL4_IS_SLOW
611    
612    checkpoint52 = ecco_c52_e35
613    o after testing adjoints of checkpoint51u_post
614    
615    checkpoint51u_post
616    o this is the post-merge tag of the ecco-branch
617      (needs another clean checkout and re-testing)
618    o various natl_box_adjoint configs and results
619      but no input fields
620    o obcs adjoint not yet merged!
621    o adding ECCO global 1x1 and 2x2 degree configs
622    o updated/extended some store directives for seaice
623    o pkg/ecco now containes ecco-specific part of cost function
624    o top level routines the_main_loop, forward_step
625      supersede those in model/src/
626      previous input data.cost now in data.ecco
627      (new namelist ecco_cost_nml)
628    o in ctrl/ cleaned some cross-dependencies and updated CPP options
629    
630    checkpoint51t_post
631    o this is the pre-merge tag of the ecco-branch
632    
633    checkpoint51s_post
634    o cleanup: removed various obsolete #define-s
635    o pkg/grdchk
636      - renamed 'ph-grd 3' to 'grad-res'
637      - merged from ecco-branch
638        (remaining bug fixes for obcs gradient checks)
639      - additional high-precision output for testreport
640        (grep for 'precision_grdchk_result')
641    
642    checkpoint51r_post
643    o cleaned up or removed CPP_OPTIONS.h files
644    o updated results for some of the tests to reflect the new
645      optfiles (-ieee: -O0 instead of -O3)
646    
647    checkpoint51q_post
648    o cd_code:
649      - moved cd_scheme.F -> cd_code_scheme.F
650      - separate read_checkpoint from cd_code_ini_vars.F
651      - separated cd_code part from write_checkpoint
652      - updated AD_SOURCE, generated .flow
653      - added CD_CODE_VARS.h to the_main_loop
654      - Moving cd_code specific store dir.s to pkg/cd_code
655    o ctrl package totally restructured
656      - pack/unpack now optional and decoupled from
657        xx_/adxx_ I/O
658      - ctrl_pack/unpack cleaned
659        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
660      - confined inclusion of AD_CONFIG.h to where necessary.
661    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
662    
663    checkpoint51p_post
664    o create initial cd_code package
665      - WARNING: the initialization of fields within packages
666        is broken because INI_FIELDS (where READ_CHECKPOINT is
667        called) is called *before* PACKAGES_INIT_VARIABLES.
668        This seems to be backwards since
669        1) its important to initially zero the entire field including
670           the "halo" region
671        2) zeroing needs to be done *before* reading pickup info
672           and the pickup call might or might not happen in any
673           particular run
674      - this needs an overhaul for R2
675    o cleanup verification/*/code/GMREDI_OPTIONS.h
676    o cleanup testreport
677    
678    checkpoint51o_post
679    o bringing AD-related verif's up to date with genmake2

686    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
687    o bug fix in find_alpha.F for MDJWF:
688      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
689        change rho -> rho-rhoConst
690      - replace call find_rho to find_rhonum
691    o initialisation of rFlx extended to full array (required by TAF)
692      and shifted to thermodynamics
693    o removed PTRACERS.h in ptracers routine

712        (this means new output.txt for global_ocean.90x40x15,
713         global_ocean.cs32x15, and global_with_exf)
714    o added surface flux output variables to TIMEAVE_STATVARS
715    
716    checkpoint51n_pre
717    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

739    o enable to apply restoring on S & T only in a latitude band.
740    o update output (external_forcing_surf modif. change truncation errors)
741       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
742    
743    checkpoint51k_post
744    o change default to: useNHMTerms=.FALSE.
745     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
746       adjustment.128x64x1, aim.5l_Eq_Ch, aim.5l_LatLon, hs94.128x64x5, hs94.1x64x5

769           - pkg_ad_check_lev?_dir.h
770    
771    checkpoint51i_post

802    checkpoint51f_pre
803    o Added on-the-fly spatial interpolation capability
804        "USE_EXF_INTERPOLATION" to pkg/exf.
805      - This is a temporary Cartesian-grid hack until
806        the super-duper ESMF coupler becomes available.
807      - See verification/global_with_exf/README for usage example.
808      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
809        flags and modified pkg/seaice accordingly.
810    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
811        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
812        non-local transport term.
813    
814    checkpoint51e_post
815    o pkg/mom_vecinv:
816      - changes related to hFac: use S/R from aim.5l_cs/code (coriolis & vort.advec)
817      - add time-ave diagnostic of vorticity advection.
818    o add diagnostic (instantaneous) of Shapiro Filter effect for T,S & UV.
819    o atmospheric geopotential: - include water vapor effect;
820                                - use p^kappa in p* scaling.
821    o land pkg: read initial state from files.
822    o AIM : add stratospheric drag in the upper level
823    
824    checkpoint51d_post
825    o change function ILNBLNK (=> last non-blank char.) to return zero
826      (instead of the string length) when the string. char is empty
827    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
828    o modif's to restore TAMC compatibility
829      - avoid "_d" constructs in PARAMETER declarations
830      - avoid interrupting lines by comment lines
831    o Use cluster local disks for purely local I/O
832      vs. globally visible disks needed for ctrl stuff
833      (merged from ecco-branch)
834      - new active_file_loc... and mdsio_..._loc routines
835      - affected packages: autodiff, ctrl, grdchk, mdsio
836    
837    checkpoint51c_post
838    o introducing integer flag debugLevel
839      - debLevZero: suppress all output
840      - debLevA: standard
841      - debLevB: equivalent to current debugMode=.TRUE.
842    o introducing pathname variable mdsioLocalDir for mdsio
843      that can be specified at runtime
844      (relevant for cluster I/O to local disk)
845    `
846    >>>checkpoint51b_post
847    adjoint of ptracers
848    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
849    o extended state in checkpoint_lev?, etc.
850    o alternative ctrl/cost with tr1 or ptracer
851    o new comlev1_bibj_ptracers
852    o new ptracers.flow
853    o made ptracers_forcing same as external_forcing_s
854    o added verification for adjoint with ptracers
855      - adm. grdchk fail so far
856      - tlm. grdchk OK
857      - checked tapelev/comlev recomputations: OK
858    <<<checkpoint51b_pre
859    
860    checkpoint51a_post
861    o added code for biogeochemistry package
862      - new pkgs: dic, gchem
863      - new subroutine in ptracers
864    o modify code for biogeo packages
865      - in model/src and pkg/ptracers
866    
867  checkpoint51  checkpoint51
868  o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN  o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
869    - autodiff, ctrl, exf, grdchk, seaice    - autodiff, ctrl, exf, grdchk, seaice
