3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o add ability of MNC to write local and "partial" (eg. 2D slices where
7      the full 3D field is never actually stored) arrays to NetCDF files
8      with the correct (that is, the complete multi-dimensional) set of
9      array indicies
10      - used in mom_vecinv() to write the diagFreq output
11      - tested (demonstrated) in verification/aim.5l_cs
12    o further mnc-ification
13      - add verification/lab_sea to the list with mnc setups
14      - fix undefined mnc v-names in cd_code
15      - add kpp to mnc output (both snapshot and timeave)
16    o non-hydrostatic code
17      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
18        in calc_gw.F
19      - defaults to viscAh
20      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
21        friction or Leith) in non-hydrostatic mode, as long as there is
22        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
23    o pkg/cost
24      extend simple cost functions to treat time mean quantities
25      (T,U,V) via cost_accumulate_state from cost_tile
26    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
27        be 2 times larger than the minimum size the advection scheme requires.
28        now get a perfect conservation of salt in advect_cs test-exp (updated)
29    o GGL90 (Gaspar's TKE mixed layer)
30      - add horizontal diffusion of TKE, requires exchanges in
31        do_fields_blocking_exchanges, horizontal diffusivity is zero by
32        default. In OPA there is no horizontal diffusion of TKE but the
33        mixing coefficients are computed from a horizontal average of TKE of
34        6 points or so. I think that diffusion has a little more physical
35        justification.
36      - clean up ggl90_calc in the hope of reducing memory usage (this hope
37        was in vain)
38      - mask tke-variable in ggl90_init
39    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
40    o fix biharmonic diffusion on CS-grid.
41    o more obcs stuff
42      - added obcs_external_fields_load as an alternative to the EXF-pkg option
43        for reading boundary values. This routine is called from
44        obcs_prescribe_read
45      - updated obcs_check
46      - changed sponge layer relaxation parameter units for days to seconds
47      - turned off sponge layer by default
48      - changed argument list of OBCS_CALC to myTime+deltaTclock
49      - fixed about 35 bugs in obcs_external_fields_load
50    
51    checkpoint55c_post
52    o obcs stuff
53      - new runtime flags useOBCSprescribe, useOBCSbalance
54      - re-arranged obcs_calc
55      - moved exf_getobcs to obcs_prescibe_read
56        obcs_prescibe_read is called after ORLANSKI stuff
57        and independent of it (executable can contain all).
58      - updated obcs_check
59      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
60        These may be necessary only if tangential velocities are
61        prescribed at OB, not sure, needs testing.
62    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
63      which simplifies the calls and passes the ifc check-bounds test
64    
65    checkpoint55b_post
66    o add a 2D scalar, Z location, exchange_2 routine.
67    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
68      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
69      affects advect_cs results (for the wrong reason): update output.txt
70    o use a more standard discretization for biharmonic viscosity ;
71     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
72      affects results of dome set-up: update output.txt
73    o fix gad_advection.F (CubedSphere part), back to version 1.23
74    o fix bug in mom_vi_del2uv.F (CubedSphere part).
75    
76    checkpoint55a_post
77    o merged code to
78      * prescribe/read time-dependent open boundaries
79        (works in conjunction with exf, cal)
80      * sponge layer code for open boundaries
81      * each boundary N/S/E/W now has its own CPP option
82        (healthy for the adjoint)
83    
84    checkpoint55
85    o up-to-date adjoint of previous breaks
86      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
87      - global_ocean_ebm: adjoint still needs fix (TLM ok)
88      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
89      - carbon: * remove tr1-related adjoint verification
90                * add ptracer as control variable
91    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
92      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
93    
94    checkpoint54f_post
95    o in verification/carbin/ remove experiment related to
96      ALLOW_PASSIVE_TRACER (array tr1 etc)
97      code_ad/ input_ad/ results_ad
98    
99    o add two new packages
100      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
101        + subject to optimization (memory)
102      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
103        + subject to reordering (many GOTOs in the original code)
104        + so far opps is called for every (i,j) point, and then operates in
105          the vertical; one may want to reorder the scheme in order operate in
106          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
107          fields)
108    o overhaul of IO so that we now have flags for MDSIO and/or MNC
109      - all verification tests compile and run with linux_ia32_g77
110      - defaults are compatible with current input files--nothing
111        should change if you were not previously using MNC
112      - MNC output has been added in numerous places (eg. timeave)
113        but there are still a few writes not yet do-able with MNC
114        (this is in progress)
115      - flags now allow for either/or/both use of MDSIO and MNC and
116        documentation will soon follow
117      - numerous small formatting cleanups for ProTeX
118    o add version info (via BUILD_INFO.h) to MNC and stdout
119    
120    checkpoint54e_post
121    o add two new packages
122      - pp81 (Packanowski and Philander, 1981), Richardson number and
123        stratification dependent mixing
124      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
125      - these scheme operate in a similar manner as KPP (without ghat, of
126        course), however there is only one diffusivity that is used for both
127        temperature and salinity (and passive tracers)ç
128    o add offline package
129    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
130      provided by Stephanie Dutkiewicz
131    o genmake2: add ability to search for C compilers and cleanup test output
132      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
133    
134    checkpoint54d_post
135    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
136    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
137      leading to additional shift by 5 days each year of integration
138       (i.e. leading to considerable offset over the years)
139    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
140    o start with no AB and no initial filtering (staggerTimeStep):
141      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
142    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
143      (external loading & cpl import/export stay in forward_step.F)
144    o update coupling interface to work with new staggerTimeStep
145    o change MDSIO ptracers_pickup.
146    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
147    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
148    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
149    
150    checkpoint54c_post
151    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
152      this affects (truncation error) output.txt of test-exp:
153       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
154    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
155    o change Qnet to always be the net heat flux, (+upward).
156      affects (truncation error) output of natl_box exp.: updated
157    o define the max number of passive tracers in PTRACERS_SIZE.h
158    o start to test mnc routinely in exp0
159    o add sea-ice loading (sIceLoad) as a new forcing field.
160    
161    checkpoint54b_post
162    o add testreport "-j JOBS" option for parallel builds (tested and pretty
163       impressive on Altix and Opteron systems)
164    o diagnostics can now write NetCDF files through the mnc package
165    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
166    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
167    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
168      affects (truncation error) output of lab_sea & natl_box exp.: updated
169    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
170    
171    checkpoint54a_post
172    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
173    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
174    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
175    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
176      + internal_wave (shift in writing cg2d_ini_res)
177    checkpoint54a_pre
178    
179    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
180      - modified verification/lab_sea and natl_box_adjoint accordingly
181    
182    checkpoint54
183    checkpoint53g_post
184    o prepare splitting of thermodynamics: store convect.counter in common block
185    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
186      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
187    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
188    o new parameter "nShapS": allow to treat differently S from T (nShapT)
189    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
190    o restore adjointability
191    
192    checkpoint53f_post
193    o modifications that affect AIM experiment results (update output.txt):
194      - no advection of S at top interface Nr (pkg/generic_advdiff)
195      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
196    o AIM pkg:
197      - include stability function into surf.Flux derivative relative to Tsurf
198      - calculate clear-sky radiation & surface temp. change (for diagnostics)
199    
200    checkpoint53e_post
201    o merged cylindrical coord configuration
202    o added rotating_tank experiment
203    checkpoint53e_pre
204    
205    checkpoint53d_post
206    o faulks upgraded: re-generate output.txt that have changed:
207       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
208    o Added Bryan and Lewis, 1979, vertical diffusivity profile
209    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
210    o added Sadourny discretization of Coriolis
211      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
212      - re-enabled use of omega3 (useAbsVorticity)
213    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
214      vector-invariant equations
215      - note: does *NOT* yet use same variable visc. for no-slip BC's.
216    o recoded the lateral boundary conditions for non-hydrostatic w, this time
217      hopefully without new bugs
218      - still to do: biharmonic friction for non-hydrostatic w
219    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
220    o regenerated output for global_ocean_ebm (using -ieee)
221    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
222      of mom_common/
223      - simple re-arrangement of instructions within computing loop
224    checkpoint53d_pre
225    
226    checkpoint53c_post
227    o new version of coupler for AIM+thSIce and Ocean models
228     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
229     - land: change Evaporation of snow
230     - aim with thSIce: fix bug in snow-precip.
231    o changes to calc_gw.F
232     - bug fix for w^2 term near the bottom boundary
233     - (hopefully) improve the lateral slip boundary condtions for use with
234        partial/looped cells
235      - because the bug fix changes two verification experiments anyway (exp5
236        and plume on slope), change the lateral boundary condition from half slip
237        to the value of no_slip_sides
238    o ebm package wasnt quite up to the parallel task. Fixed that.
239    o Adjoint of EBM package + verification
240      * TLM OK
241      * ADM not sufficient accuracy yet (needs further testing)
242    
243    checkpoint53b_post
244    o Commiting new energy balance model to repository
245      * package is pkg/ebm
246      * verif. is verification/global_ocean_ebm
247      * references are in ebm_driver.F
248    C      * X. Wang, P. Stone and J. Marotzke, 1999:
249    C        Global thermohaline circulation. Part I:
250    C        Sensitivity to atmospheric moisture transport.
251    C        J. Climate 12(1), 71-82
252    C      * X. Wang, P. Stone and J. Marotzke, 1999:
253    C        Global thermohaline circulation. Part II:
254    C        Sensitivity with interactive transport.
255    C        J. Climate 12(1), 83-91
256    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
257    C        Destabilization of the thermohaline circulation
258    C        by atmospheric eddy transports.
259    C        J. Climate 7(12), 1870-1882
260    o Will need long integration testing.
261    checkpoint53b_pre
262    
263    o created pkg/mom_common in preparation for variable viscosity code
264    o renamed and split ini_mnc_io
265    o pkg/land: only liquid water can diffuse or run-off
266    o AIM using land: soil wetness availability account for snow
267    o added printMapIncludesZeros to EEPARMS namelist
268    
269    checkpoint53a_post
270    o restore TAMC compatiility for exf_constants.h
271      (no usage of _d in .h)
272    o Additional storing in KPP in an attempt to fix
273      TAMC problem with adjoint of KPP code.
274      (no success...)
275      Identical code works fine with TAF.
276    o Fixed verification/natl_box_adjoint experiments.
277      Initial conditions for Experiments 4 and 5 are now
278      set to "SEAICE_initialHEFF=0", which is more reasonable,
279      and hence gives results closer to that of Experiment 2.
280      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
281    
282    checkpoint53
283    o stable checkpoint with up to date adjoint
284      TLM tests only run for 1st grdchk at the moment. Its unclear if
285      this is a code problem or a problem with resetting code for g_
286      variables that is being autogenerated wrong.
287      Otherwise:
288       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
289       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
290         are both still in chaos following their security messes.
291    
292    checkpoint52n_post
293    o various build (mostly genmake2) changes including:
294      - ability to build/run more easily within Cygwin and MacOS X
295      - more complicated Makefiles with a stronger dependence on Gnu Make
296    o pkg/seaice modifications
297      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
298        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
299        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
300      - changed proxy for geostrophic velocity and updated
301        verification/lab_sea/results/* accordingly
302      - removed ADI dynamic solver from pkg/seaice
303      - replaced all occurrences of 1/CSTICE or 1/CSUICE
304        they caused a segmentation fault under certain circumstances
305      - removed unused field WATR
306    o bug fix in exf-package:
307      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
308         now reflect that.
309    o small fixes in the cal-package:
310      - set reference date to first of January for the 'model'-calendar
311      - failing of cal_CheckDate in cal_FullDate now actually results in a
312        warning
313    o small modifications in exf-package to increase flexibility:
314      - change climtempfreeze from a constant to a runtime parameter that
315        is specified in data.exf_clim (default = -1.9)
316      - introduce runtime parameter windstressmax (default = 2.0) that is
317        specified in data.exf
318    o fix in pkg/thsice:
319      - update Evap (Tsf changes) to be consistent with Latent heat flux
320      - maintain snow precipitation unchanged (even if Tsf >=0).
321     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
322    
323    checkpoint52m_post
324    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
325      this does not change any of the results, because myIter=0 in swfrac always
326      lead to jwtype=2 (the default anyway), but the call makes little sense
327      as a default
328    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
329    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
330      atmospheric model (AIM) to use it ; add a "slab ocean" component.
331    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
332    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
333    o extending useSingleCpuIO option to work with new exch2 I/O format
334      - old-style, missing-tile I/O is still accessible by defining CPP
335        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
336    o monitor package can write to NetCDF files and/or STDOUT
337    o fix re-definition bug in MNC_GRID_INIT_ALL()
338    o doc/api_reference added
339      - a framework for building an API Reference Manual using all
340        the "protex" comments embedded in the code
341      - see pkg/generic_advdiff, pkg/mnc for examples
342    o MNC:
343      - make myThid the last argument for all subroutines
344      - new default for the grid files: NO halos
345      - add useMNC and other run-time flags
346      - separate per-file-group handling of the unlimited dimension
347      - early initialization of MNC w/ flags read at the eeboot stage
348        and lookup tables set in initialize_fixed
349      - write all MNC output to a freshly-created directory
350    o thermodynamics sea-ice (thsice) is now tested with testreport.
351    o test exp. advect_cs: use the standard cs32 grid ; update output.
352    o Added functionality to grdchk:
353      pick global i,j,k position (or nearest wet) where to perform check.
354    
355    checkpoint52l_post
356    o new land formulation:
357      a) use ground enthalpy as prognostic variable to ensure exact
358         energy conservation.
359      b) account for water temperature and for latent heat of freezing
360         in all processes (rain, run-off, ground storage)
361      c) compute surface and ground temperature implicitly.
362    o aim_v23 modification for new land model:
363      a) Treat separately land / ocean / sea-ice surface fluxes
364         to allow implicit computation of land & sea-ice surface temp.
365      b) add snow precipitation.
366    checkpoint52l_pre
367    
368    o fix problem (when 1 tile is empty) in min/max monitor.
369    o fix bug in timeAve (u,vZetatave in common block)
370    o no restoring terms under ice for pkg/seaice
371    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
372    o bug fix for pkg/seaice pickups
373    o change MNC call locations and add coordinate attributes
374    o mask vorticity at the corner ; affects global_ocean.cs output
375    o fix ini_curvilinear_grid ; test CS experiments with mpi
376    o aim.5l_cs: modify sea-ice fraction input file ; update output
377    o exf: Adding simple range check routine for exf fields after read
378    
379    checkpoint52k_post
380    o removed top-level directory "diags"
381      - we migrated these functions to pkg/timeave a long time ago
382    o fixed bug introduced in pkg/monitor
383    o accuracy ctrlprec = 32 insuffient for gradient checks using
384      averaged fields (I/O via cost_averages)
385      -> use ctrl.h in active_file*.F to control I/O precision.
386    o paramter list of CALL ADTHE_MAIN_LOOP
387    o added initial do_the_model_io to ecco
388    o set all ...Freq to zero after cost_final

393    o fix nchklev in tamc.h for global_ocean...
394    o Bringing flow and store directives up-to-date
395    o Really weird thing!
396      call do_the_model_io from the_main_loop with parameters
397      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
398      TAF places a faulty re-call of initialise_varia
399      after cost_final call which should not be there!
400    checkpoint52j_pre
401

442    checkpoint52e_post
443    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
444      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
445    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
446      to work with implicit vertical advection and AB ;
447    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
448    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
449     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
450    checkpoint52e_pre
451    
452    o fix bug in impldiff when Nr=1 or Nr=2.
453    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
454    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
455    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2

462    o re-tiled many expts to allow comparison in multi-processor mode
463      - updated output accordingly
464      - changed hs94.128x64x5 to use intial T from file rather than use the
465        random number generator
466    o add infrastructure in model routines for fizhi and gridalt packages
467    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
468    o changes to permit hi-res, cubed-sphere, configuration
469      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
470      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
471      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
472        of surface winds for the cube
473      (A verification experiment, based on global_ocean.cs32x15, but with
474       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
475       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
476       complete with example surface forcing files and matlab scripts to look
477       at the output and compare it with that of global_ocean.cs32x15.)
478    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
479       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
480       to conform to the common rule.
481    o check-in the first version of the coupler + interfaces for multi-components
482       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
483       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
484       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
485       - ocean and atmos. share the same horizontal grid (no interpolation).
486       - exchanges between component and coupler is done in forward_step
487    o new verification experiment, cpl_aim+ocn:
488       coupled ocean - AIM atmosphere on cs32 grid.
489    
490    checkpoint52d_pre
491    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
492    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
493    
494    checkpoint52c_post
495    o Fixing OPTIONS files for use of exf:
496      - ALLOW_ECCO not needed
497      - ECCO_CPPOPTIONS.h should not be included from
498        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
499        as has been the case in the past
500      - All cal/exf related options are currently set in
501        single header file. Should remain so until we
502        agree on a consistent new policy.
503    o Removed all CPP options for cal package.
504      cal has no more CPP options.
505    o modified STOREs in GAD_ADVECTION
506    o corrected key comp. for passkey
507    
508    checkpoint52b_post

511     - modify fluxes but do not change theta directly;
512     - light cleaning of bulk_force pkg (still needed with thsice).
513     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
514       + output_thsice.txt to test thsice & bulk_force pkgs.
515    o put back grid & coriolis monitor output.
516    checkpoint52b_pre
517    
518    o call "do_the_model_io" at the beginning (=> dump initial state)
519    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
520    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
521      (need info on NUMBER_OF_PTRACERS)
522    o missing PTRACERS headers in some routines
523    o default tamc.h in pkg/autodiff supposed to crash
524      to ensure proper customization
525    
526    checkpoint52a_post
527    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
528      - moved surfaceTendencyTice from pkg/seaice to main code
529      - subroutine FREEZE_SURFACE now limits only surface temperature
530        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
531        => new output.txt for global_ocean.cs32x15 & global_with_exf
532      - keep the old version of FREEZE for backward compatibility;
533        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

542    o some bug fixes for #undef REAL4_IS_SLOW
543    
544    checkpoint52 = ecco_c52_e35
545    o after testing adjoints of checkpoint51u_post
546    
547    checkpoint51u_post
548    o this is the post-merge tag of the ecco-branch
549      (needs another clean checkout and re-testing)
550    o various natl_box_adjoint configs and results
551      but no input fields
552    o obcs adjoint not yet merged!
553    o adding ECCO global 1x1 and 2x2 degree configs
554    o updated/extended some store directives for seaice
555    o pkg/ecco now containes ecco-specific part of cost function

557      supersede those in model/src/
558      previous input data.cost now in data.ecco
559      (new namelist ecco_cost_nml)
560    o in ctrl/ cleaned some cross-dependencies and updated CPP options
561    
562    checkpoint51t_post
563    o this is the pre-merge tag of the ecco-branch
564    
565    checkpoint51s_post
566    o cleanup: removed various obsolete #define-s
567    o pkg/grdchk
568      - renamed 'ph-grd 3' to 'grad-res'
569      - merged from ecco-branch
570        (remaining bug fixes for obcs gradient checks)
571      - additional high-precision output for testreport
572        (grep for 'precision_grdchk_result')
573    
574    checkpoint51r_post
575    o cleaned up or removed CPP_OPTIONS.h files
576    o updated results for some of the tests to reflect the new
577      optfiles (-ieee: -O0 instead of -O3)
578    
579    checkpoint51q_post
580    o cd_code:
581      - moved cd_scheme.F -> cd_code_scheme.F
582      - separate read_checkpoint from cd_code_ini_vars.F
583      - separated cd_code part from write_checkpoint
584      - updated AD_SOURCE, generated .flow

586      - Moving cd_code specific store dir.s to pkg/cd_code
587    o ctrl package totally restructured
588      - pack/unpack now optional and decoupled from
589        xx_/adxx_ I/O

592      - confined inclusion of AD_CONFIG.h to where necessary.
593    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
594    
595    checkpoint51p_post
596    o create initial cd_code package
597      - WARNING: the initialization of fields within packages
598        is broken because INI_FIELDS (where READ_CHECKPOINT is
599        called) is called *before* PACKAGES_INIT_VARIABLES.
600        This seems to be backwards since
601        1) its important to initially zero the entire field including
602           the "halo" region
603        2) zeroing needs to be done *before* reading pickup info
604           and the pickup call might or might not happen in any
605           particular run
606      - this needs an overhaul for R2
607    o cleanup verification/*/code/GMREDI_OPTIONS.h
608    o cleanup testreport
609

645         global_ocean.cs32x15, and global_with_exf)
646    o added surface flux output variables to TIMEAVE_STATVARS
647    
648    checkpoint51n_pre
649    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

805      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
806    
807    checkpoint50i_post
808    o Preparing next differentiable checkpoint and sync
809      of MAIN vs. ecco-branch
810      - 1st step: this one is differentiable
811      - 2nd step: next(! not this) checkpoint will have updated packages
812                  from ecco-branch)
813    
814    checkpoint50h_post
815    o new package "land": provide surface BC for AIM.
816    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
817    o AIM: use true log-P extrapolation for near surface temp (= as in
818        F.Molteni paper) ; update aim.5l_cs output.
819    o New variable in PARM03 for more flexible pickups
820    o somewhat cleaned package initialisation sequence for
821      ctrl/ cost/ ecco/ in packages_... routines
822    
823    checkpoint50g_post
824    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
825      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
826      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
827        made the default because of faster convergence than ADI
828    
829    checkpoint50f_post
830    o exf totally restructured
831      - replaced all exf_set_ routines by one generic exf_set_gen.F
832        and made sure it's still differentiable
833      - split exf_getffields.F into new exf_bulkformulae.F
834      - exf_inscal_/exf_outscal_ suffixes consistent with field names
835      - updated adjoint/makefile and relevant verif. accordingly
836    
837    checkpoint50f_pre
838     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
839          + change Evap over land. (update aim.5l_cs output)
840     o added missing .cvsignores and made uniform across expts
841     o changed configuration of tidal_basin_2d expt
842     o added pkg/debug functions for tracing code in fatal crashes
843     o tidied pkg/monitor to use MONITOR_OPTIONS.h
844     o new fn in pkg/monitor to stop model if solution grows too big
845     o removed lots of single quotes from comments
846    
847    checkpoint50e_post
848    o make KPP work with PTRACERS
849     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
850       nearly a copy of kpp_transport_s
851     - there is no analogue to SurfaceTendencyS, so I have to use
852       gPtr(of the surface layer) instead
853    o add a new platform SunFire+mpi (SunFire 15000) to genmake
854    checkpoint50e_pre
855    
856    checkpoint50d_post
857    o change kpp output from multiple-record state files to single-record state
858      files analogous to write_state.F
859    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
860      analogous to the cg2d-related output.
861    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
862      so that writing to internal file fn (with length 512) fails.
863    checkpoint50d_pre
864    
865    checkpoint50c_post
866    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
867    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
868    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
869    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
870    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
871    
872    checkpoint50c_pre
873    Merging from release1_p13:
874    o bug fix for pkg/seaice dynamic solver
875    o Added SEAICE_initialHEFF to pkg/seaice
876    
877    checkpoint50b_post
878    o store u*,v* in gU,V instead of in guNm1,gvNm1
879    o in order to put the momForcing out of the Adams-Bashforth:
880      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
881      to timestep.F
882    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
883    o re-generate output for highly sensitive test-exp:
884       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
885    
886    checkpoint50b_pre
887    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
888    o corrected CPP option mismatch in exf_Bulk... functions for case
889      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
890    
891    checkpoint50a_post
892    o Bug fix for merging between c50 and KPP.
893      ikey was passed from thermodynamics to kpp_calc via
894      common block rather than being recomputed in kpp_calc,
895      in contradiction with new key itdkey.
896      New key ikppkey created, and tamc.h headers updated.
897    
898    checkpoint50
899    - 2nd step of merge with ecco-branch:
900      merge changes in ecco-branch back into main trunk
901    - bug fix in find_alpha
902    - more storing in gmredi_calc_tensor.F, kpp_routines.F
903    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
904    - merged some sliced AD support routines
905    
906    checkpoint49
907    merged from ecco-branch:
908    o exf:
909      - Enable initialisation of forcing fields to constant
910        (runtime) values.
911      - in exf_getffields.F
912        Reduce i-/j-loop to interior domain, discarding overlaps.
913        That also fixes wrong TAF-key computations for key_1, key_2
914        with bulf formulae.
915      - exf_init.F modify #ifdef for exf_init_evap
916      - exf_getffieldrec.F, ctrl_getrec.F
917        The following INT-usages are not safe:
918          fldsecs  = int(fldsecs/fldperiod)*fldperiod
919          fldcount = int(fldsecs/fldperiod) + 1
920        and were modified.
921    o autodiff: checkpoint_lev...
922      - updated storing for bulk formulae (some arrays were missing)
923      - added state for seaice package
924      - synchronized with main branch
925    o DIVA:
926      Modif.s in
927      - the_main_loop.F
928      - the_model_main.F
929      and added cost_final_restore.F cost_final_store.F
930      o With these changes, it is possible to fully separate
931        the first forward run to compute the cost function (mdthe_main_loop)
932        and adjoint runs over individual DIVA intervals (adthe_main_loop)
933        into separate model executions.
934        This enables better tuning of DIVA to given queue sizes.
935      o Loss of cost function value in consecutive DIVA runs is
936        fixed by storing to 'costfinal' file.
937      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
938        beginning/end of adjoint integration is accounted for.
939      The current changes apply to TAF-1.4.26.
940      TAF has one remaining bug, requiring one manual change
941      (see MITgcm manual).
942    o cal: synchronized between MAIN and ecco-branch
943    
944    checkpoint48i_post
945    o Changes to restore differentiability of code w.r.t. previous tag
946      (mostly adding new routines to make list and replacing
947      pressure by totPhiHyd).
948    o Updated and merged grdchk package
949      - has both ADM and TLM checks
950      - works for single- and multi-proc.
951      - output cleaned
952      - worked successfully for parallel DIVA
953    o genmake:
954      - Adding -platform=SP4
955      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
956    o Modif. for DIVA:
957      ctrl_unpack should not be called in intermediate DIVA interval.
958      (similar thing would apply for active files such as
959      tbar, sbar, psbar, which should not be reinitialised;
960      only relevant for ecco-branch)
961    
962    checkpoint48h_post
963    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
964    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
965    o Added SEAICE_initialHEFF to pkg/seaice
966    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
967    
968    checkpoint48g_post
969    --- EOS:
970    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
971      store total Potential in totPhyHyd for diagnostics & EOS.
972    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
973    --- Pressure/geopotential gradient:
974    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
975    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
976      ( changes results of global_ocean_pressure )
977    o NLFS + z-coord.: add eta*Rho' contribution.
978    o accurate phiHyd when using interface-W at the middle between 2 centers
979     ( changes results of ideal_2D_oce )
980    o includes r* 2nd term in potential gradient.
981    
982    checkpoint48f_post
983    Merging from release1_p12:
984    o Modifications for using pkg/exf with pkg/seaice
985      - improved description of the various forcing configurations
986      - added basic radiation bulk formulae to pkg/exf
987      - units/sign fix for evap computation in exf_getffields.F
988      - updated verification/global_with_exf/results/output.txt
989    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
990      (SBO) core products, including oceanic mass, center-of-mass,
991      angular, and bottom pressure (see pkg/sbo/README.sbo).
992    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
993      to avoid negative values in shallow regions.
994      - updated verification/natl_box/results/output.txt
995      - updated verification/lab_sea/results/output.txt
996    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
997    o Added useSingleCpuIO option (see PARAMS.h).
998    o Updated useSingleCpuIO option in mdsio_writefield.F to
999      work with multi-field files, e.g., for single-file pickup.
1000    o pkg/seaice:
1001      - bug fix in growth.F: QNET for no shortwave case
1002      - added HeffFile for specifying initial sea-ice thickness
1003      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1004    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1005      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1006    o pkg/seaice:
1007      - adjoint-friendly modifications
1008      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1009    
1010    checkpoint48e_post
1011    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1012    o dynamics: change definition of computational domain & adapt mom_fluxform
1013      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1014    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1015        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1016        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1017        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1018        inverted_barometer solid-body.cs-32x32x1
1019      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1020    
1021    checkpoint48d_post
1022    o in preparation for r*:
1023     a) use pre-computed gradient of hydrostatic potential:
1024        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1025     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1026        => affects results of glob_oce_pressure (different truncation error)  
1027      update output.txt of ideal_2D_oce & global_ocean_pressure
1028    
1029    checkpoint48d_pre
1030    o in preparation for r*:
1031      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1032      pass the 2 comp. of the grad. as arguments to momentum S/R.
1033      but for the moment, only used if it does not change the results.
1034    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1035    
1036    checkpoint48c_post
1037    Modifications in treatment of initial flux forcing controls
1038    to avoid extra storing of flux fields.
1039    
1040    checkpoint48c_pre
1041    o Added tidal_basin_2d experiment (currently 1D!)
1042    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1043    
1044    checkpoint48b_post
1045    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1046     (modification to pressure gradient not yet implemented)
1047    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1048      (for U & V) that are used for vertical advection of momentum.
1049    
1050    checkpoint48a_post
1051    o In preparation for r*, use temp. array to compute vertical transport
1052       in flux-form momentum pkg. => change results of few test-exp.
1053      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1054                        lab_sea, natl_box & plume_on_slope
1055    
1056    checkpoint48
1057    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1058    
1059    checkpoint47j_post
1060    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1061    o moved adexch from forward_step to addummy_in_stepping
1062    o added exch in ctrl_map_...
1063    o aveFreq.=0. at end of cost_final to avoid overwrite in
1064      reverse checkpointing loop
1065    o Yet more changes in gmredi:
1066      * adgmredi_calc_tensor
1067        avoiding all recomputation of gmredi_slope_limit
1068      * adgmredi_x/y/rtransport
1069        added flag for excessive storing to avoid recomp. of
1070        u/v/rtans, dTdx/y/z
1071        -> this is not really necessary and very memory-consuming
1072      * adgmredi_slope_psi:
1073        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1074      * gmredi_slope_limit
1075        re-activated full calculation of taperfct for case 'ac02'
1076    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1077    
1078    checkpoint47i_post
1079    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1080    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1081      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1082    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1083    o gmredi: fix few bugs.
1084    
1085    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1086    This will be a good checkpoint to plug into the ecco-branch.
1087    o few modif.'s to get latest version adjointed
1088      (mainly kick out code in ini_linear_phisurf)
1089    o modif's to run adjoint with exactConserv
1090    o case GM_BOLUS_ADVEC should be cleaned
1091      S/R gmredi_slope_psi should be cleaned
1092    o verification/carbon now has exactConserv=.TRUE.
1093    
1094    checkpoint47g_post
1095    o time-average AIM output: becomes independent from statvars time-average
1096      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1097    o After TAF bug fix:
1098      Tested adjoint of gmredi package.
1099      Tests were done with checkpoint47 rather than with latest
1100      checkpoint47f_post since the latter is broken for the adjoint
1101      verification/carbon/ contains both ADM and TLM gradient checks.
1102    Here they are, before they get changed/lost/stolen.
1103    Mostly modif.'s to fix numerical sensitivities.
1104    Gradient checks OK for
1105    - GM_taper_scheme:
1106      * clipping
1107      * ac02
1108      * linear
1109      * glw91
1110      * dm95
1111      * ldd97
1112    - GMREDI_OPTIONS:
1113      * GM_VISBECK_VARIABLE_K
1114      * GM_NON_UNITY_DIAGONAL
1115      * GM_EXTRA_DIAGONAL
1116      * GM_BOLUS_ADVEC
1117    in conjunction with data.gmredi parameters to be checked in
1118    in a few minutes under verification/carbon/code/
1119    
1120    checkpoint47f_post
1121    Merging from release1_p10:
1122    o modifications for using pkg/exf with pkg/seaice
1123      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1124        and SEAICE_EXTERNAL_FLUXES
1125      - pkg/exf CPP options EXF_READ_EVAP and
1126        EXF_NO_BULK_COMPUTATIONS
1127      - usage examples are Experiments 8 and 9 in
1128        verification/lab_sea/README
1129      - verification/lab_sea default experiment now uses
1130        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1131    
1132    checkpoint47e_post
1133    o created a tag prior to creating a branch
1134    
1135    checkpoint47d_post
1136    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1137      at the bottom boundary had an erroneous half slip boundary condition
1138    o added bottom drag and no slip boundary condition capabilities to
1139      oceanic pressure coordinates code
1140    o added new verification experiment global_ocean_pressure, this experiment is
1141      also described in the tutorial section of the manual
1142    checkpoint47d_pre
1143    
1144    checkpoint47c_post
1145    o Added a verification experiment for a global cubed-sphere ocean run
1146      -  verification/global_ocean.cubed32x32x30
1147      -  uses pkg/therm_seaice and pkg/bulk_forcing
1148    
1149    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1150    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1151      when using P-coordinate; only implemented for atmospheric config.
1152    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1153      NOTES: requires option NONLIN_FRSURF to be "#define".
1154    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1155    
1156    checkpoint47b_post
1157    Merging from release1_p9:
1158    o pkg/seaice
1159      - removed GOTO's and added taf directives
