3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o genmake2: add ability to search for C compilers and cleanup test output
7      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
8    
9    checkpoint54d_post
10    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
11    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
12      leading to additional shift by 5 days each year of integration
13       (i.e. leading to considerable offset over the years)
14    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
15    o start with no AB and no initial filtering (staggerTimeStep):
16      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
17    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
18      (external loading & cpl import/export stay in forward_step.F)
19    o update coupling interface to work with new staggerTimeStep
20    o change MDSIO ptracers_pickup.
21    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
22    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
23    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
24    
25    checkpoint54c_post
26    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
27      this affects (truncation error) output.txt of test-exp:
28       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
29    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
30    o change Qnet to always be the net heat flux, (+upward).
31      affects (truncation error) output of natl_box exp.: updated
32    o define the max number of passive tracers in PTRACERS_SIZE.h
33    o start to test mnc routinely in exp0
34    o add sea-ice loading (sIceLoad) as a new forcing field.
35    
36    checkpoint54b_post
37    o add testreport "-j JOBS" option for parallel builds (tested and pretty
38       impressive on Altix and Opteron systems)
39    o diagnostics can now write NetCDF files through the mnc package
40    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
41    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
42    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
43      affects (truncation error) output of lab_sea & natl_box exp.: updated
44    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
45    
46    checkpoint54a_post
47    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
48    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
49    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
50    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
51      + internal_wave (shift in writing cg2d_ini_res)
52    checkpoint54a_pre
53    
54    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
55      - modified verification/lab_sea and natl_box_adjoint accordingly
56    
57    checkpoint54
58    checkpoint53g_post
59    o prepare splitting of thermodynamics: store convect.counter in common block
60    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
61      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
62    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
63    o new parameter "nShapS": allow to treat differently S from T (nShapT)
64    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
65    o restore adjointability
66    
67    checkpoint53f_post
68    o modifications that affect AIM experiment results (update output.txt):
69      - no advection of S at top interface Nr (pkg/generic_advdiff)
70      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
71    o AIM pkg:
72      - include stability function into surf.Flux derivative relative to Tsurf
73      - calculate clear-sky radiation & surface temp. change (for diagnostics)
74    
75    checkpoint53e_post
76    o merged cylindrical coord configuration
77    o added rotating_tank experiment
78    checkpoint53e_pre
79    
80    checkpoint53d_post
81    o faulks upgraded: re-generate output.txt that have changed:
82       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
83    o Added Bryan and Lewis, 1979, vertical diffusivity profile
84    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
85    o added Sadourny discretization of Coriolis
86      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
87      - re-enabled use of omega3 (useAbsVorticity)
88    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
89      vector-invariant equations
90      - note: does *NOT* yet use same variable visc. for no-slip BC's.
91    o recoded the lateral boundary conditions for non-hydrostatic w, this time
92      hopefully without new bugs
93      - still to do: biharmonic friction for non-hydrostatic w
94    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
95    o regenerated output for global_ocean_ebm (using -ieee)
96    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
97      of mom_common/
98      - simple re-arrangement of instructions within computing loop
99    checkpoint53d_pre
100    
101    checkpoint53c_post
102    o new version of coupler for AIM+thSIce and Ocean models
103     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
104     - land: change Evaporation of snow
105     - aim with thSIce: fix bug in snow-precip.
106    o changes to calc_gw.F
107     - bug fix for w^2 term near the bottom boundary
108     - (hopefully) improve the lateral slip boundary condtions for use with
109        partial/looped cells
110      - because the bug fix changes two verification experiments anyway (exp5
111        and plume on slope), change the lateral boundary condition from half slip
112        to the value of no_slip_sides
113    o ebm package wasnt quite up to the parallel task. Fixed that.
114    o Adjoint of EBM package + verification
115      * TLM OK
116      * ADM not sufficient accuracy yet (needs further testing)
117    
118    checkpoint53b_post
119    o Commiting new energy balance model to repository
120      * package is pkg/ebm
121      * verif. is verification/global_ocean_ebm
122      * references are in ebm_driver.F
123    C      * X. Wang, P. Stone and J. Marotzke, 1999:
124    C        Global thermohaline circulation. Part I:
125    C        Sensitivity to atmospheric moisture transport.
126    C        J. Climate 12(1), 71-82
127    C      * X. Wang, P. Stone and J. Marotzke, 1999:
128    C        Global thermohaline circulation. Part II:
129    C        Sensitivity with interactive transport.
130    C        J. Climate 12(1), 83-91
131    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
132    C        Destabilization of the thermohaline circulation
133    C        by atmospheric eddy transports.
134    C        J. Climate 7(12), 1870-1882
135    o Will need long integration testing.
136    checkpoint53b_pre
137    
138    o created pkg/mom_common in preparation for variable viscosity code
139    o renamed and split ini_mnc_io
140    o pkg/land: only liquid water can diffuse or run-off
141    o AIM using land: soil wetness availability account for snow
142    o added printMapIncludesZeros to EEPARMS namelist
143    
144    checkpoint53a_post
145    o restore TAMC compatiility for exf_constants.h
146      (no usage of _d in .h)
147    o Additional storing in KPP in an attempt to fix
148      TAMC problem with adjoint of KPP code.
149      (no success...)
150      Identical code works fine with TAF.
151    o Fixed verification/natl_box_adjoint experiments.
152      Initial conditions for Experiments 4 and 5 are now
153      set to "SEAICE_initialHEFF=0", which is more reasonable,
154      and hence gives results closer to that of Experiment 2.
155      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
156    
157    checkpoint53
158    o stable checkpoint with up to date adjoint
159      TLM tests only run for 1st grdchk at the moment. Its unclear if
160      this is a code problem or a problem with resetting code for g_
161      variables that is being autogenerated wrong.
162      Otherwise:
163       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
164       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
165         are both still in chaos following their security messes.
166    
167    checkpoint52n_post
168    o various build (mostly genmake2) changes including:
169      - ability to build/run more easily within Cygwin and MacOS X
170      - more complicated Makefiles with a stronger dependence on Gnu Make
171    o pkg/seaice modifications
172      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
173        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
174        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
175      - changed proxy for geostrophic velocity and updated
176        verification/lab_sea/results/* accordingly
177      - removed ADI dynamic solver from pkg/seaice
178      - replaced all occurrences of 1/CSTICE or 1/CSUICE
179        they caused a segmentation fault under certain circumstances
180      - removed unused field WATR
181    o bug fix in exf-package:
182      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
183         now reflect that.
184    o small fixes in the cal-package:
185      - set reference date to first of January for the 'model'-calendar
186      - failing of cal_CheckDate in cal_FullDate now actually results in a
187        warning
188    o small modifications in exf-package to increase flexibility:
189      - change climtempfreeze from a constant to a runtime parameter that
190        is specified in data.exf_clim (default = -1.9)
191      - introduce runtime parameter windstressmax (default = 2.0) that is
192        specified in data.exf
193    o fix in pkg/thsice:
194      - update Evap (Tsf changes) to be consistent with Latent heat flux
195      - maintain snow precipitation unchanged (even if Tsf >=0).
196     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
197    
198    checkpoint52m_post
199    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
200      this does not change any of the results, because myIter=0 in swfrac always
201      lead to jwtype=2 (the default anyway), but the call makes little sense
202      as a default
203    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
204    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
205      atmospheric model (AIM) to use it ; add a "slab ocean" component.
206    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
207    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
208    o extending useSingleCpuIO option to work with new exch2 I/O format
209      - old-style, missing-tile I/O is still accessible by defining CPP
210        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
211    o monitor package can write to NetCDF files and/or STDOUT
212    o fix re-definition bug in MNC_GRID_INIT_ALL()
213    o doc/api_reference added
214      - a framework for building an API Reference Manual using all
215        the "protex" comments embedded in the code
216      - see pkg/generic_advdiff, pkg/mnc for examples
217    o MNC:
218      - make myThid the last argument for all subroutines
219      - new default for the grid files: NO halos
220      - add useMNC and other run-time flags
221      - separate per-file-group handling of the unlimited dimension
222      - early initialization of MNC w/ flags read at the eeboot stage
223        and lookup tables set in initialize_fixed
224      - write all MNC output to a freshly-created directory
225    o thermodynamics sea-ice (thsice) is now tested with testreport.
226    o test exp. advect_cs: use the standard cs32 grid ; update output.
227    o Added functionality to grdchk:
228      pick global i,j,k position (or nearest wet) where to perform check.
229    
230    checkpoint52l_post
231    o new land formulation:
232      a) use ground enthalpy as prognostic variable to ensure exact
233         energy conservation.
234      b) account for water temperature and for latent heat of freezing
235         in all processes (rain, run-off, ground storage)
236      c) compute surface and ground temperature implicitly.
237    o aim_v23 modification for new land model:
238      a) Treat separately land / ocean / sea-ice surface fluxes
239         to allow implicit computation of land & sea-ice surface temp.
240      b) add snow precipitation.
241    checkpoint52l_pre
242    
243    o fix problem (when 1 tile is empty) in min/max monitor.
244    o fix bug in timeAve (u,vZetatave in common block)
245    o no restoring terms under ice for pkg/seaice
246    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
247    o bug fix for pkg/seaice pickups
248    o change MNC call locations and add coordinate attributes
249    o mask vorticity at the corner ; affects global_ocean.cs output
250    o fix ini_curvilinear_grid ; test CS experiments with mpi
251    o aim.5l_cs: modify sea-ice fraction input file ; update output
252    o exf: Adding simple range check routine for exf fields after read
253    
254    checkpoint52k_post
255    o removed top-level directory "diags"
256      - we migrated these functions to pkg/timeave a long time ago
257    o fixed bug introduced in pkg/monitor
258    o accuracy ctrlprec = 32 insuffient for gradient checks using
259      averaged fields (I/O via cost_averages)
260      -> use ctrl.h in active_file*.F to control I/O precision.
261    o paramter list of CALL ADTHE_MAIN_LOOP
262    o added initial do_the_model_io to ecco
263    o set all ...Freq to zero after cost_final
264      taveFreq, dumpFreq, pChkptFreq
265    o MAIN and ECCO differentiability restored
266    
267    checkpoint52j_post
268    o fix nchklev in tamc.h for global_ocean...
269    o Bringing flow and store directives up-to-date
270    o Really weird thing!
271      call do_the_model_io from the_main_loop with parameters
272      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
273      TAF places a faulty re-call of initialise_varia
274      after cost_final call which should not be there!
275    checkpoint52j_pre
276    
277    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
278      error messages
279    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
280    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
281      debug output
282    o modfied mdsio_writefield.F to handle non-global files under exch2
283    o update AIM Cubed-Sphere exp (aim.5l_cs):
284      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
285    o update AIM Equatorial Channel exp:
286      use standard aim_v23 pkg and change the SST fields to be more realistic.
287    o globalFile now works with exch2
288    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
289      mon_vort3.F to make exch2 friendly with >1 tile per cube face
290    o limit timeave output for hi-res integrations
291    
292    checkpoint52i_post
293    o removed CPP_EEOPTIONS.h from verification/*/code
294    o updated the tiling for global_ocean_pressure
295    checkpoint52i_pre
296    
297    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
298      the old pkg/aim).
299    
300    checkpoint52h_pre
301    o shortened offending lines in exch2_send_rx?.template
302    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
303    o genmake2: add build & execute test for NetCDF code
304    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
305      old grid files, moved CPP_EEMACROS.h to pkg/exch2
306    o added useSingleCPUIO flag to monitor.F and mon_out.F
307    o added temporary hack for sea-ice dynamics on the cube:
308      metric terms are ignored and it is assumed that
309      there is no sea-ice on cube faces 1, 2, 4, and 5.
310    
311    checkpoint52f_post
312    o added exch2 cube routines to pkg/exch2
313    o modified hs94.cs-32x32x5 to use it
314    o added new grid files to hs94.cs-32x32x5
315    checkpoint52f_pre
316    
317    checkpoint52e_post
318    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
319      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
320    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
321      to work with implicit vertical advection and AB ;
322    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
323    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
324     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
325    checkpoint52e_pre
326    
327    o fix bug in impldiff when Nr=1 or Nr=2.
328    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
329    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
330    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
331      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
332    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
333    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
334    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
335    
336    checkpoint52d_post
337    o re-tiled many expts to allow comparison in multi-processor mode
338      - updated output accordingly
339      - changed hs94.128x64x5 to use intial T from file rather than use the
340        random number generator
341    o add infrastructure in model routines for fizhi and gridalt packages
342    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
343    o changes to permit hi-res, cubed-sphere, configuration
344      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
345      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
346      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
347        of surface winds for the cube
348      (A verification experiment, based on global_ocean.cs32x15, but with
349       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
350       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
351       complete with example surface forcing files and matlab scripts to look
352       at the output and compare it with that of global_ocean.cs32x15.)
353    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
354       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
355       to conform to the common rule.
356    o check-in the first version of the coupler + interfaces for multi-components
357       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
358       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
359       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
360       - ocean and atmos. share the same horizontal grid (no interpolation).
361       - exchanges between component and coupler is done in forward_step
362    o new verification experiment, cpl_aim+ocn:
363       coupled ocean - AIM atmosphere on cs32 grid.
364    
365    checkpoint52d_pre
366    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
367    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
368    
369    checkpoint52c_post
370    o Fixing OPTIONS files for use of exf:
371      - ALLOW_ECCO not needed
372      - ECCO_CPPOPTIONS.h should not be included from
373        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
374        as has been the case in the past
375      - All cal/exf related options are currently set in
376        single header file. Should remain so until we
377        agree on a consistent new policy.
378    o Removed all CPP options for cal package.
379      cal has no more CPP options.
380    o modified STOREs in GAD_ADVECTION
381    o corrected key comp. for passkey
382    
383    checkpoint52b_post
384    o new version: "thsice" of thermodynamic sea-ice pkg:
385     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
386     - modify fluxes but do not change theta directly;
387     - light cleaning of bulk_force pkg (still needed with thsice).
388     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
389       + output_thsice.txt to test thsice & bulk_force pkgs.

395    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
396      (need info on NUMBER_OF_PTRACERS)
397    o missing PTRACERS headers in some routines
398    o default tamc.h in pkg/autodiff supposed to crash
399      to ensure proper customization
400    
401    checkpoint52a_post
402    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
403      - moved surfaceTendencyTice from pkg/seaice to main code
404      - subroutine FREEZE_SURFACE now limits only surface temperature
405        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
406        => new output.txt for global_ocean.cs32x15 & global_with_exf
407      - keep the old version of FREEZE for backward compatibility;
408        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

419    checkpoint52 = ecco_c52_e35
420    o after testing adjoints of checkpoint51u_post
421    
422    checkpoint51u_post
423    o this is the post-merge tag of the ecco-branch
424      (needs another clean checkout and re-testing)
425    o various natl_box_adjoint configs and results
426      but no input fields
427    o obcs adjoint not yet merged!
428    o adding ECCO global 1x1 and 2x2 degree configs
429    o updated/extended some store directives for seaice
430    o pkg/ecco now containes ecco-specific part of cost function

432      supersede those in model/src/
433      previous input data.cost now in data.ecco
434      (new namelist ecco_cost_nml)
435    o in ctrl/ cleaned some cross-dependencies and updated CPP options
436    
437    checkpoint51t_post
438    o this is the pre-merge tag of the ecco-branch
439    
440    checkpoint51s_post
441    o cleanup: removed various obsolete #define-s
442    o pkg/grdchk
443      - renamed 'ph-grd 3' to 'grad-res'
444      - merged from ecco-branch
445        (remaining bug fixes for obcs gradient checks)
446      - additional high-precision output for testreport

448    
449    checkpoint51r_post
450    o cleaned up or removed CPP_OPTIONS.h files
451    o updated results for some of the tests to reflect the new
452      optfiles (-ieee: -O0 instead of -O3)
453    
454    checkpoint51q_post
455    o cd_code:
456      - moved cd_scheme.F -> cd_code_scheme.F
457      - separate read_checkpoint from cd_code_ini_vars.F
458      - separated cd_code part from write_checkpoint

467      - confined inclusion of AD_CONFIG.h to where necessary.
468    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
469    
470    checkpoint51p_post
471    o create initial cd_code package
472      - WARNING: the initialization of fields within packages
473        is broken because INI_FIELDS (where READ_CHECKPOINT is
474        called) is called *before* PACKAGES_INIT_VARIABLES.
475        This seems to be backwards since
476        1) its important to initially zero the entire field including
477           the "halo" region
478        2) zeroing needs to be done *before* reading pickup info
479           and the pickup call might or might not happen in any
480           particular run
481      - this needs an overhaul for R2
482    o cleanup verification/*/code/GMREDI_OPTIONS.h
483    o cleanup testreport
484    
485    checkpoint51o_post
486    o bringing AD-related verif's up to date with genmake2

520         global_ocean.cs32x15, and global_with_exf)
521    o added surface flux output variables to TIMEAVE_STATVARS
522    
523    checkpoint51n_pre
524    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

549    
550    checkpoint51k_post
551    o change default to: useNHMTerms=.FALSE.
552     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
553       adjustment.128x64x1, aim.5l_Eq_Ch, aim.5l_LatLon, hs94.128x64x5, hs94.1x64x5

559      (and change sign: back to "logical" value: +1 when R increases downward)
560    o added an include barrier to the default CPP_OPTIONS.h and
561      removed the #include "PACKAGES_CONFIG.h" from it
562    o fix a bug in mom_fluxform (from chk51j_post)

571      Moving pkg-specific differentiation list to corresponding pkg
572      Moving pkg-specific checkpoint-lev storing to corresponding pkg
573      ---> conventions are
574           - pkg_ad.flow
575           - pkg_ad_diff.list
576           - pkg_ad_check_lev?_dir.h
577    
578    checkpoint51i_post
579    o merge of the branch-genmake2
580      - knowingly breaks the older genmake

607      of tracer Green's fucntions for ocean inversion project.
608    
609    checkpoint51f_pre
610    o Added on-the-fly spatial interpolation capability
611        "USE_EXF_INTERPOLATION" to pkg/exf.
612      - This is a temporary Cartesian-grid hack until
613        the super-duper ESMF coupler becomes available.
614      - See verification/global_with_exf/README for usage example.
615      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
616        flags and modified pkg/seaice accordingly.
617    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,

620    
621    checkpoint51e_post
622    o pkg/mom_vecinv:

644    checkpoint51c_post
645    o introducing integer flag debugLevel
646      - debLevZero: suppress all output
647      - debLevA: standard
648      - debLevB: equivalent to current debugMode=.TRUE.
649    o introducing pathname variable mdsioLocalDir for mdsio
650      that can be specified at runtime
651      (relevant for cluster I/O to local disk)
652    `
653    >>>checkpoint51b_post
654    adjoint of ptracers
655    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM

663      - tlm. grdchk OK
664      - checked tapelev/comlev recomputations: OK
665    <<<checkpoint51b_pre
666    
667    checkpoint51a_post
668    o added code for biogeochemistry package
669      - new pkgs: dic, gchem
670      - new subroutine in ptracers
671    o modify code for biogeo packages
672      - in model/src and pkg/ptracers
673    
674    checkpoint51
675    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
676      - autodiff, ctrl, exf, grdchk, seaice
677      kept separate packages
678      - cost, ecco, obcs
679    o updating verification/internal_wave, verification/lab_sea
680      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
681    
682    checkpoint50i_post
683    o Preparing next differentiable checkpoint and sync
684      of MAIN vs. ecco-branch
685      - 1st step: this one is differentiable
686      - 2nd step: next(! not this) checkpoint will have updated packages
687                  from ecco-branch)
688    
689    checkpoint50h_post
690    o new package "land": provide surface BC for AIM.
691    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
692    o AIM: use true log-P extrapolation for near surface temp (= as in
693        F.Molteni paper) ; update aim.5l_cs output.
694    o New variable in PARM03 for more flexible pickups
695    o somewhat cleaned package initialisation sequence for
696      ctrl/ cost/ ecco/ in packages_... routines
697    
698    checkpoint50g_post
699    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
700      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
701      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
702        made the default because of faster convergence than ADI
703    
704    checkpoint50f_post
705    o exf totally restructured
706      - replaced all exf_set_ routines by one generic exf_set_gen.F
707        and made sure it's still differentiable
708      - split exf_getffields.F into new exf_bulkformulae.F
709      - exf_inscal_/exf_outscal_ suffixes consistent with field names

720     o removed lots of single quotes from comments
721    
722    checkpoint50e_post
723    o make KPP work with PTRACERS
724     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
725       nearly a copy of kpp_transport_s
726     - there is no analogue to SurfaceTendencyS, so I have to use
727       gPtr(of the surface layer) instead
728    o add a new platform SunFire+mpi (SunFire 15000) to genmake
729    checkpoint50e_pre
730    
731    checkpoint50d_post
732    o change kpp output from multiple-record state files to single-record state
733      files analogous to write_state.F
734    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
735      analogous to the cg2d-related output.
736    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
737      so that writing to internal file fn (with length 512) fails.
738    checkpoint50d_pre
739    
740    checkpoint50c_post
741    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)

743    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
744    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
745    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
746    
747    checkpoint50c_pre
748    Merging from release1_p13:
749    o bug fix for pkg/seaice dynamic solver
750    o Added SEAICE_initialHEFF to pkg/seaice
751    
752    checkpoint50b_post
753    o store u*,v* in gU,V instead of in guNm1,gvNm1
754    o in order to put the momForcing out of the Adams-Bashforth:
755      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
756      to timestep.F
757    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
758    o re-generate output for highly sensitive test-exp:
759       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
760    
761    checkpoint50b_pre
762    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
763    o corrected CPP option mismatch in exf_Bulk... functions for case
764      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
765    
766    checkpoint50a_post
767    o Bug fix for merging between c50 and KPP.
768      ikey was passed from thermodynamics to kpp_calc via
769      common block rather than being recomputed in kpp_calc,
770      in contradiction with new key itdkey.
771      New key ikppkey created, and tamc.h headers updated.
772    
773    checkpoint50
774    - 2nd step of merge with ecco-branch:
775      merge changes in ecco-branch back into main trunk
776    - bug fix in find_alpha
777    - more storing in gmredi_calc_tensor.F, kpp_routines.F
778    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
779    - merged some sliced AD support routines
780    
781    checkpoint49
782    merged from ecco-branch:
783    o exf:
784      - Enable initialisation of forcing fields to constant
785        (runtime) values.
786      - in exf_getffields.F
787        Reduce i-/j-loop to interior domain, discarding overlaps.
788        That also fixes wrong TAF-key computations for key_1, key_2
789        with bulf formulae.
790      - exf_init.F modify #ifdef for exf_init_evap
791      - exf_getffieldrec.F, ctrl_getrec.F
792        The following INT-usages are not safe:
793          fldsecs  = int(fldsecs/fldperiod)*fldperiod
794          fldcount = int(fldsecs/fldperiod) + 1
795        and were modified.
796    o autodiff: checkpoint_lev...
797      - updated storing for bulk formulae (some arrays were missing)
798      - added state for seaice package
799      - synchronized with main branch
800    o DIVA:
801      Modif.s in
802      - the_main_loop.F
803      - the_model_main.F
804      and added cost_final_restore.F cost_final_store.F
805      o With these changes, it is possible to fully separate
806        the first forward run to compute the cost function (mdthe_main_loop)
807        and adjoint runs over individual DIVA intervals (adthe_main_loop)
808        into separate model executions.
809        This enables better tuning of DIVA to given queue sizes.
810      o Loss of cost function value in consecutive DIVA runs is
811        fixed by storing to 'costfinal' file.
812      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
813        beginning/end of adjoint integration is accounted for.
814      The current changes apply to TAF-1.4.26.
815      TAF has one remaining bug, requiring one manual change
816      (see MITgcm manual).
817    o cal: synchronized between MAIN and ecco-branch
818    
819    checkpoint48i_post
820    o Changes to restore differentiability of code w.r.t. previous tag
821      (mostly adding new routines to make list and replacing
822      pressure by totPhiHyd).
823    o Updated and merged grdchk package
824      - has both ADM and TLM checks
825      - works for single- and multi-proc.
826      - output cleaned
827      - worked successfully for parallel DIVA
828    o genmake:
829      - Adding -platform=SP4
830      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
831    o Modif. for DIVA:
832      ctrl_unpack should not be called in intermediate DIVA interval.
833      (similar thing would apply for active files such as
834      tbar, sbar, psbar, which should not be reinitialised;
835      only relevant for ecco-branch)
836    
837    checkpoint48h_post
838    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
839    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
840    o Added SEAICE_initialHEFF to pkg/seaice
841    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
842    
843    checkpoint48g_post
844    --- EOS:
845    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
846      store total Potential in totPhyHyd for diagnostics & EOS.
847    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
848    --- Pressure/geopotential gradient:
849    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
850    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
851      ( changes results of global_ocean_pressure )
852    o NLFS + z-coord.: add eta*Rho' contribution.
853    o accurate phiHyd when using interface-W at the middle between 2 centers
854     ( changes results of ideal_2D_oce )
855    o includes r* 2nd term in potential gradient.
856    
857    checkpoint48f_post
858    Merging from release1_p12:
859    o Modifications for using pkg/exf with pkg/seaice
860      - improved description of the various forcing configurations
861      - added basic radiation bulk formulae to pkg/exf
862      - units/sign fix for evap computation in exf_getffields.F
863      - updated verification/global_with_exf/results/output.txt
864    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
865      (SBO) core products, including oceanic mass, center-of-mass,
866      angular, and bottom pressure (see pkg/sbo/README.sbo).
867    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
868      to avoid negative values in shallow regions.
869      - updated verification/natl_box/results/output.txt
870      - updated verification/lab_sea/results/output.txt
871    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
872    o Added useSingleCpuIO option (see PARAMS.h).
873    o Updated useSingleCpuIO option in mdsio_writefield.F to
874      work with multi-field files, e.g., for single-file pickup.
875    o pkg/seaice:
876      - bug fix in growth.F: QNET for no shortwave case
877      - added HeffFile for specifying initial sea-ice thickness
878      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
879    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
880      kpp_transport_t.F, forward_step.F, and the_main_loop.F
881    o pkg/seaice:
882      - adjoint-friendly modifications
883      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
884    
885    checkpoint48e_post
886    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
887    o dynamics: change definition of computational domain & adapt mom_fluxform
888      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
889    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
890        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
891        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
892        global_ocean.90x40x15 global_with_exf global_ocean_pressure
893        inverted_barometer solid-body.cs-32x32x1
894      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
895    
896    checkpoint48d_post
897    o in preparation for r*:
898     a) use pre-computed gradient of hydrostatic potential:
899        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
900     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
901        => affects results of glob_oce_pressure (different truncation error)  
902      update output.txt of ideal_2D_oce & global_ocean_pressure
903    
904    checkpoint48d_pre
905    o in preparation for r*:
906      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
907      pass the 2 comp. of the grad. as arguments to momentum S/R.
908      but for the moment, only used if it does not change the results.
909    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
910    
911    checkpoint48c_post
912    Modifications in treatment of initial flux forcing controls
913    to avoid extra storing of flux fields.
914    
915    checkpoint48c_pre
916    o Added tidal_basin_2d experiment (currently 1D!)
917    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
918    
919    checkpoint48b_post
920    o r* coordinate added in #ifdef NONLIN_FRSURF block.
921     (modification to pressure gradient not yet implemented)
922    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
923      (for U & V) that are used for vertical advection of momentum.
924    
925    checkpoint48a_post
926    o In preparation for r*, use temp. array to compute vertical transport
927       in flux-form momentum pkg. => change results of few test-exp.
928      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
929                        lab_sea, natl_box & plume_on_slope
930    
931    checkpoint48
932    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
933    
934    checkpoint47j_post
935    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
936    o moved adexch from forward_step to addummy_in_stepping
937    o added exch in ctrl_map_...
938    o aveFreq.=0. at end of cost_final to avoid overwrite in
939      reverse checkpointing loop
940    o Yet more changes in gmredi:
941      * adgmredi_calc_tensor
942        avoiding all recomputation of gmredi_slope_limit
943      * adgmredi_x/y/rtransport
944        added flag for excessive storing to avoid recomp. of
945        u/v/rtans, dTdx/y/z
946        -> this is not really necessary and very memory-consuming
947      * adgmredi_slope_psi:
948        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
949      * gmredi_slope_limit
950        re-activated full calculation of taperfct for case 'ac02'
951    o updating verification/ adjoints of carbon, global_ocean.90x40x15
952    
953    checkpoint47i_post
954    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
955    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
956      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
957    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
958    o gmredi: fix few bugs.
959    
960    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
961    This will be a good checkpoint to plug into the ecco-branch.
962    o few modif.'s to get latest version adjointed
963      (mainly kick out code in ini_linear_phisurf)
964    o modif's to run adjoint with exactConserv
965    o case GM_BOLUS_ADVEC should be cleaned
966      S/R gmredi_slope_psi should be cleaned
967    o verification/carbon now has exactConserv=.TRUE.
968    
969    checkpoint47g_post
970    o time-average AIM output: becomes independent from statvars time-average
971      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
972    o After TAF bug fix:
973      Tested adjoint of gmredi package.
974      Tests were done with checkpoint47 rather than with latest
975      checkpoint47f_post since the latter is broken for the adjoint
976      verification/carbon/ contains both ADM and TLM gradient checks.
977    Here they are, before they get changed/lost/stolen.
978    Mostly modif.'s to fix numerical sensitivities.
979    Gradient checks OK for
980    - GM_taper_scheme:
981      * clipping
982      * ac02
983      * linear
984      * glw91
985      * dm95
986      * ldd97
987    - GMREDI_OPTIONS:
988      * GM_VISBECK_VARIABLE_K
989      * GM_NON_UNITY_DIAGONAL
990      * GM_EXTRA_DIAGONAL
991      * GM_BOLUS_ADVEC
992    in conjunction with data.gmredi parameters to be checked in
993    in a few minutes under verification/carbon/code/
994    
995    checkpoint47f_post
996    Merging from release1_p10:
997    o modifications for using pkg/exf with pkg/seaice
998      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
999        and SEAICE_EXTERNAL_FLUXES
1000      - pkg/exf CPP options EXF_READ_EVAP and
1001        EXF_NO_BULK_COMPUTATIONS
1002      - usage examples are Experiments 8 and 9 in
1003        verification/lab_sea/README
1004      - verification/lab_sea default experiment now uses
1005        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1006    
1007    checkpoint47e_post
1008    o created a tag prior to creating a branch
1009    
1010    checkpoint47d_post
1011    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1012      at the bottom boundary had an erroneous half slip boundary condition
1013    o added bottom drag and no slip boundary condition capabilities to
1014      oceanic pressure coordinates code
1015    o added new verification experiment global_ocean_pressure, this experiment is
1016      also described in the tutorial section of the manual
1017    checkpoint47d_pre
1018    
1019    checkpoint47c_post
1020    o Added a verification experiment for a global cubed-sphere ocean run
1021      -  verification/global_ocean.cubed32x32x30
1022      -  uses pkg/therm_seaice and pkg/bulk_forcing
1023    
1024    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1025    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1026      when using P-coordinate; only implemented for atmospheric config.
1027    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1028      NOTES: requires option NONLIN_FRSURF to be "#define".
1029    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1030    
1031    checkpoint47b_post
1032    Merging from release1_p9:
1033    o pkg/seaice
1034      - removed GOTO's and added taf directives
1035      - double precision constants to reduce the g77 (Linux)
1036        to F77 (SGI) differences reported in release1_p8
1037    o tools/genmake
1038      - added SGI options
1039    o verification/testscript
1040      - updated to that of checkpoint47a_post
1041    o verification/global_ocean.90x40x15/input/eedata
1042      - modified for SGI f77 compatibility
1043    o verification/lab_sea
1044      - added description of sea-ice model
1045      - added missing matlab routines
1046      - added test of thermodynamics parallelization
1047    
1048    checkpoint47a_post
1049    o new pkg: aim_v23
1050     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1051       for now, keep the same surface forcing as before.
1052     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1053     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1054     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1055    o add diagnostic of surface correction term in monitor output
1056    
1057    o bulk_force and therm_seaice
1058    - Two packages:  bulk_force (Bulk forcing)
1059      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1060    - Earlier integration from Stephaine Dutkiewicz
1061      and Patrick Heimbach.
1062    - Two ifdef statements for compile time,
1063       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1064    
1065    checkpoint47
1066    differentiable version of checkpoint46n_post
1067    o bug fix in quasihydrostaticterms
1068    o * "clean" adjoint code (in terms of extensive recomputations)
1069        can now be obtained for all GMREDI options (i.e. for
1070        - GM_VISBECK_VARIABLE_K
1071        - GM_NON_UNITY_DIAGONAL
1072        - GM_EXTRA_DIAGONAL
1073        - GM_BOLUS_ADVEC )
1074      * However, wrong gradient check problem remains unsolved.
1075      * New CPP options have been introduced for different
1076        tapering schemes
1077    o external_fields_load now part of differentiation list
1078    o pressure needs multiple storing;
1079      would be nice to have store_pressure at beginning or
1080      end of forward_step, e.g. by having phiHyd global (5-dim.)
1081      (NB: pressure is needed for certain cases in find_rho,
1082      which is also invoked through convective_adjustment).
1083    o recomputations in find_rho for cases
1084     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1085    o #define ATMOSPHERIC_LOADING should be differentiable
1086    o ini_forcing shifted to begining of initialise_varia
1087    o Incorporating QNVS line search routines into MITgcm
1088      (this is separate code, and therefore not under pkg)
1089      lsopt/, optim/
1090    o Updated verification/carbon/
1091      - #define GM_VISBECK_VARIABLE_K
1092      - GM_taper_scheme    = 'ldd97'    
1093    
1094    checkpoint46n_post
1095    Merging from release1_p8:
1096    o verification/natl_box:
1097      updating new external_fields_load routine
1098    o New package: pkg/seaice
1099      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1100      The sea-ice code is based on Hibler (1979-1980).
1101      Two sea-ice dynamic solvers, ADI and LSR, are included.
1102      In addition to computing prognostic sea-ice variables and diagnosing
1103      the forcing/external data fields that drive the ocean model,
1104      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1105      The implied surface heat flux is then stored in variable
1106      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1107      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1108      non-local transport term.  Because this call precedes model
1109      thermodynamics, temperature under sea-ice may not be "exactly" at
1110      the freezing point by the time theta is dumped or time-averaged.
1111      N.B.: fairly large differences in accuracy occur across
1112            different platforms/compilers; comparison between
1113            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1114            generated output gives:
1115       T           S           U           V
1116      C D M    c        m  s        m  s        m  s        m  s
1117      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
1118      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d
1119      g d e n  d  n  x  n  .  n  x  n  .  n  x  n  .  n  x  n  .
1120    
1121      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1122    o GAD:
1123      - generated new common blocks to account for call of
1124        same gad routines with differing traceridentities
1125        (needed to modify tracerIdentity indices in GAD.h)
1126      - generated separate common blocks for case useCubedSphereExchange
1127        (Department of Futurology)
1128      - parameter lists to gmredi_?transport: added tracerIdentity
1129      - added new key indices to tamc.h
1130    o external_fields_load:
1131      - added this routine to TAF list
1132      - needed to make some common blocks global and additional storing
1133        along the same lines as exf package (checkpoint_lev?_directives.h)
1134    o exf:
1135      updated external forcing package
1136      - bug fixes carried over from ecco-branch
1137        (missing OBCS_OPTIONS.h in two routines)
1138      - enable easy to use "no forcing".
1139      - added exf I/O for atmospheric loading
1140      - added exf I/O for runoff data
1141      - transfered scaling between exf <-> MITgcm to exf namelist
1142    o Adding new verification experiment global_with_exf.
1143      This verification experiment is almost identical to the
1144      global_ocean.90x40x15 experiment, except that it uses
1145      the exf (and cal) package instead of the
1146      external_fields_load routine (cf README file).
1147    
1148    checkpoint46m_post
1149    o modified testscript to return -- when there are no lines of "%MON" output
1150    o added new flag "quasiHydrostatic" for QH mode
1151      and new routine quasihydrostaticterms()
1152    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1153      New routine: mom_u_coriolis_nh()
1154    o fixed sign of non-hydrostatic metric terms in u and v equations.
1155      Depend on correct sign of gravitySign.
1156    o added work.pc* to .cvsignore in aim directories using ifc
1157    o introduced flag for controllin non-hydrostatic metric terms
1158    o removed gravitySign from PARM04
1159    o switched to g77/ifc from pgf77 in aim experiments
1160    
1161    checkpoint46l_post
1162    o made convective adjustment work with pressure coordinates:
1163     - changed the direction of k-loop in convective_adjustment.F for the
1164       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1165     - adjusted the reference pressure k-index in convective_adjustment.F
1166     - adjusted the convection condition in convect.F (in analogy to
1167       calc_ivdc.F)
1168     - convective_adjustment no longer computes anything on the halos
1169     - removed the warnings about negative salinity from find_rho.F and
1170       find_alpha.F; instead the new routine look_for_neg_salinity, called
1171       at the beginning of find_rho, find_alpha, and find_beta, does a
1172       check of the entire slice, if CPP-option
1173       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1174    checkpoint46l_pre
1175    
1176    checkpoint46k_post
1177    o fixed the verification/global_ocean.90x40x15 experiment:
1178     - new bathymetry (the world according to A., JMC, and M.)
1179     - new initial fields and forcing fields (*.bin files)
1180     - new POLY3.COEFFS (for the next release one should switch to a full
1181       equation of state: JMD95P or MDJWF)
1182     - fixed several errors and redundancies in the data file
1183     - experiment uses looped cells
1184     - added matlab directory with diagnostic scripts for plotting of output
1185    
1186    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1187     - read AIM physics parameters from a file (data.aimphys)
1188     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1189    
1190    checkpoint46j_post
1191    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1192    o move wVel computation at the end of the time step, in S/R integr_continuity
1193    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1194    o update timeave pkg for wVel diagnostic.
1195    checkpoint46j_pre
1196    
1197    checkpoint46i_post
1198    o Clean up AIM package (and keep the results unchanged):
1199      include CPP_OPTION and use IMPLICT NONE in all routines ;
1200      declare all the variables _RL ; use _d 0 for all numerical constants.
1201      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1202    
1203    checkpoint46h_post
1204    o cleaned up the use of rhoNil and rhoConst.
1205      - rhoNil should only appear in the LINEAR equation of state, everywhere
1206        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1207        and the dynamical equations are all divided by rhoConst
1208    o introduced new parameter rhoConstFresh, a reference density of fresh
1209      water, to remove the fresh water flux's dependence on rhoNil. The default
1210      value is 999.8 kg/m^3
1211    o cleanup up external_forcing.F and external_forcing_surf.F
1212      - can now be used by both OCEANIC and OCEANICP
1213    checkpoint46h_pre
1214    
1215     Added code to convert surface volume flux (fresh water) into
1216     a mass flux when using P coordinates in the ocean (OCEANICP).
1217     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1218    
1219    checkpoint46g_post
1220    o Include a new diagnostic variable phiHydLow for the ocean model
1221      - in z-coordinates, it is the bottom pressure anomaly
1222      - in p-coordinates, it is the sea surface elevation
1223      - in both cases, these variable have global drift, reflecting the mass
1224        drift in z-coordinates and the volume drift in p-coordinates
1225      - included time averaging for phiHydLow, be aware of the drift!
1226    o depth-dependent computation of Bo_surf for pressure coordinates
1227      in the ocean (buoyancyRelation='OCEANICP')
1228      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1229        Theta, Salinity, and Pressure in the parameter list. This routine is
1230        presently contained in find_rho.F. This routine does not give the
1231        correct density for 'POLY3', which would be a z-dependent reference
1232        density.
1233    o cleaned up find_rho
1234      - removed obsolete 'eqn' from the parameter list.
1235    o added two new verification experiments: gop and goz
1236      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1237    checkpoint46g_pre
1238    
1239    checkpoint46f_post
1240    o Enable tangent linear (forward mode) gradient checks:
1241      - extended active file handling to g_... files
1242      - added TANGENT_SIMULATION to theSimulationMode
1243      - extended grdchk package accordingly
1244    o added tangent linear setup in verification/carbon/code_ftl
1245    o added adjoint setup in verification/front_relax/code_ad
1246    
1247    checkpoint46e_post
1248    o Added new equation of state -> MDJWF
1249      - EOS of McDougall et al., 2002, JAOT, submitted
1250      - caveat: the equation of state is only valid for a smaller (more
1251        realistic?) range of values than JMD95P/Z and UNESCO
1252      - added masks to the calculation of pressure in store_pressure
1253      - added more check values for density in check_eos (ini_eos.F), some of
1254        the old check values are out of the range of the MDJWF-eos, so don't
1255        expect perfect matches for those
1256    checkpoint46e_pre
1257    
1258    checkpoint46d_post
1259    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1260      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1261      case of pressure coordinates. eosType='JMD95Z' in
1262      combination with buoyancyRelation='OCEANICP' now causes an error.
1263    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1264      in find_alpha/beta.
1265    checkpoint46d_pre
1266    
1267    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1268      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1269    
1270    checkpoint46c_post
1271    o Changes necessary for ocean in p-coordinates
1272     -  Added new buoyancy relation = 'OCEANICP'
1273     -  Added new parameters = gravitySign (this used to be contained inside
1274        the factor dRdZ which I added when we first switched to R coordinates).
1275     X GM/Redi is not compatible (yet)
1276     X bottom drag and no-slip need to be debugged.
1277    checkpoint46c_pre
1278    
1279    checkpoint46b_post
1280    o Added new equation of state -> JMD95Z and JMD95P
1281      - EOS of Jackett and McDougall, 1995, JAOT
1282      - moved all EOS parameters into EOS.h
1283      - new routines ini_eos.F, store_pressure.F
1284    o Added UNESCO EOS, but not recommended because it requires
1285      in-situ temperature (see JMD95)
1286    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1287      unesco.f to be used with POLY3
1288    checkpoint46b_pre
1289    
1290    checkpoint46a_post
1291    o Added (atmospheric) pressure loading
1292      - new field in FFIELDS.h, etc...
1293      - new cpp flag ATMOSPHERIC_LOADING
1294    o Changed hFacC to _hFacC in calc_phi_hyd.F
1295    o Added SHORTWAVE_HEATING to some files for consistency
1296    checkpoint46a_pre
1297    
1298    checkpoint46
1299    further merges from release1_p5
1300    o new ctrl package
1301      - adopted from ECCO environment to enable optimization
1302      - added Eliassen Palm fluxes to controls
1303    o added Eliassen Palm flux controls to gradient check package
1304    o cost package
1305      - Compatible with new ctrl package
1306      - added Eliassen Palm cost hooks
1307      - modif's of existing cost functions
1308    o Adjoint-related bug fixes in kpp:
1309      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1310      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1311    o autodiff package
1312      - flow directives:
1313        + new for S/R do_the_model_io

1317        disable adcommon.h/g_common.h by default.
1318      - fixed problem for adjoint of global_max
1319    o modified verification/carbon/

1321    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1322    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1323    o incorporated hooks for sponge layer code (external_forcing.F)
1324    
1325    checkpoint45d_post
1326    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1327    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1328      (affects plume_on_slope "cg2d" output)
1329    o add new parameter deltaTfreesurf for free-surface time stepping
1330    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1331    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1332    o change phiMin in exp1 (to agree with documentation)
1333    o add new flags:
1334     - T,S forcing inside/outside Adams-Bashforth
1335     - turn off temp,salt advection and/or forcing
1336     - for each tracer, define internal flag for multiDimAdvection & A-B
1337    o monitor: change definition of KE to check conservation of Energy
1338    
1339    checkpoint45c_post
1340    o Removed f90 comments ("!")
1341    o Modified initialisations to enable exf package for MITgcm
1342      (without invoking ECCO_PACKAGE).
1343    o modifications to gradient check package (Martin Losch)
1344      - enable centered differences
1345      - modified format of standard output
1346    
1347    checkpoint45b_post
1348    o cleaned exchange calls in cg2d
1349    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1350    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1351      to configure barotropic setup (Martin Losch)
1352    o moved some initialisations within bi,bj loop in dynamics
1353      (TAF flow dependency)
1354    o in initialise_varia, moved call packages_init_variables
1355      before convective_adjustment_init
1356      (corresponding adjustment of TAF tape initialisation).
1357    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1358    
1359    checkpoint45a_post
1360    o compute Rho over the whole domain (extend iMin,jMin indices)
1361    o specific exchange for X-slice domain (case Ny=1)
1362    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1363    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1364    
1365    checkpoint44h_post = checkpoint45
1366    o Fix to restore differentiability:
1367      place at which packages_init_variables is called in
1368      initialise_varia is crucial for reverse control flow.
1369    o modifications in GMRedi to enable stable adjoint
1370      (corresponding modif's in thermodynamics, dynamics)
1371    o added missing hook for sponge layer code in external_forcing
1372    o modified test cost functions
1373    o storing in gad_advection (plus removal of write(0,*)!
1374    o missing headers TR1.h added in convective_adjustment routines

1377    o modified carbon verif.
1378    
1379    checkpoint44h_pre
1380    o vertical grid option: allow to put the Interface at the middle between
1381      2 cell-centers ; replace delZ in pkg/kpp by drF.
1382    o GM Advective form: Tracers are advected using the residual transport (=
1383      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1384    
1385    checkpoint44g_post
1386    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1387      results) ; ifdef missing in thermodynamics.F
1388    
1389    checkpoint44f_pre,checkpoint44f_post
1390    o added PTRACERS package
1391      This allows an arbitrary number of passive tracers to be integrated
1392      forward simultaneously with the dynamicaly model.
1393      + Implemented so far:
1394        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1395        - I/O and checkpointing
1396        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1397      + Not implemented so far:
1398        - KPP
1399        - OBCS
1400      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1401        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1402        line in data.pkg.
1403      + This package is disabled by default since it increases storage.
1404    
1405    
1406    o testscript: added -cleanup option
1407    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
