3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
7        be 2 times larger than the minimum size the advection scheme requires.
8        now get a perfect conservation of salt in advect_cs test-exp (updated)
9    o GGL90 (Gaspar's TKE mixed layer)
10      - add horizontal diffusion of TKE, requires exchanges in
11        do_fields_blocking_exchanges, horizontal diffusivity is zero by
12        default. In OPA there is no horizontal diffusion of TKE but the
13        mixing coefficients are computed from a horizontal average of TKE of
14        6 points or so. I think that diffusion has a little more physical
15        justification.
16      - clean up ggl90_calc in the hope of reducing memory usage (this hope
17        was in vain)
18      - mask tke-variable in ggl90_init
19    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
20    o fix biharmonic diffusion on CS-grid.
21    o more obcs stuff
22      - added obcs_external_fields_load as an alternative to the EXF-pkg option
23        for reading boundary values. This routine is called from
24        obcs_prescribe_read
25      - updated obcs_check
26      - changed sponge layer relaxation parameter units for days to seconds
27      - turned off sponge layer by default
28    
29    checkpoint55c_post
30    o obcs stuff
31      - new runtime flags useOBCSprescribe, useOBCSbalance
32      - re-arranged obcs_calc
33      - moved exf_getobcs to obcs_prescibe_read
34        obcs_prescibe_read is called after ORLANSKI stuff
35        and independent of it (executable can contain all).
36      - updated obcs_check
37      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
38        These may be necessary only if tangential velocities are
39        prescribed at OB, not sure, needs testing.
40    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
41      which simplifies the calls and passes the ifc check-bounds test
42    
43    checkpoint55b_post
44    o add a 2D scalar, Z location, exchange_2 routine.
45    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
46      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
47      affects advect_cs results (for the wrong reason): update output.txt
48    o use a more standard discretization for biharmonic viscosity ;
49     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
50      affects results of dome set-up: update output.txt
51    o fix gad_advection.F (CubedSphere part), back to version 1.23
52    o fix bug in mom_vi_del2uv.F (CubedSphere part).
53    
54    checkpoint55a_post
55    o merged code to
56      * prescribe/read time-dependent open boundaries
57        (works in conjunction with exf, cal)
58      * sponge layer code for open boundaries
59      * each boundary N/S/E/W now has its own CPP option
60        (healthy for the adjoint)
61    
62    checkpoint55
63    o up-to-date adjoint of previous breaks
64      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
65      - global_ocean_ebm: adjoint still needs fix (TLM ok)
66      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
67      - carbon: * remove tr1-related adjoint verification
68                * add ptracer as control variable
69    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
70      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
71    
72    checkpoint54f_post
73    o in verification/carbin/ remove experiment related to
74      ALLOW_PASSIVE_TRACER (array tr1 etc)
75      code_ad/ input_ad/ results_ad
76    
77    o add two new packages
78      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
79        + subject to optimization (memory)
80      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
81        + subject to reordering (many GOTOs in the original code)
82        + so far opps is called for every (i,j) point, and then operates in
83          the vertical; one may want to reorder the scheme in order operate in
84          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
85          fields)
86    o overhaul of IO so that we now have flags for MDSIO and/or MNC
87      - all verification tests compile and run with linux_ia32_g77
88      - defaults are compatible with current input files--nothing
89        should change if you were not previously using MNC
90      - MNC output has been added in numerous places (eg. timeave)
91        but there are still a few writes not yet do-able with MNC
92        (this is in progress)
93      - flags now allow for either/or/both use of MDSIO and MNC and
94        documentation will soon follow
95      - numerous small formatting cleanups for ProTeX
96    o add version info (via BUILD_INFO.h) to MNC and stdout
97    
98    checkpoint54e_post
99    o add two new packages
100      - pp81 (Packanowski and Philander, 1981), Richardson number and
101        stratification dependent mixing
102      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
103      - these scheme operate in a similar manner as KPP (without ghat, of
104        course), however there is only one diffusivity that is used for both
105        temperature and salinity (and passive tracers)ç
106    o add offline package
107    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
108      provided by Stephanie Dutkiewicz
109    o genmake2: add ability to search for C compilers and cleanup test output
110      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
111    
112    checkpoint54d_post
113    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
114    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
115      leading to additional shift by 5 days each year of integration
116       (i.e. leading to considerable offset over the years)
117    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
118    o start with no AB and no initial filtering (staggerTimeStep):
119      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
120    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
121      (external loading & cpl import/export stay in forward_step.F)
122    o update coupling interface to work with new staggerTimeStep
123    o change MDSIO ptracers_pickup.
124    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
125    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
126    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
127    
128    checkpoint54c_post
129    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
130      this affects (truncation error) output.txt of test-exp:
131       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
132    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
133    o change Qnet to always be the net heat flux, (+upward).
134      affects (truncation error) output of natl_box exp.: updated
135    o define the max number of passive tracers in PTRACERS_SIZE.h
136    o start to test mnc routinely in exp0
137    o add sea-ice loading (sIceLoad) as a new forcing field.
138    
139    checkpoint54b_post
140    o add testreport "-j JOBS" option for parallel builds (tested and pretty
141       impressive on Altix and Opteron systems)
142    o diagnostics can now write NetCDF files through the mnc package
143    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
144    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
145    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
146      affects (truncation error) output of lab_sea & natl_box exp.: updated
147    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
148    
149    checkpoint54a_post
150    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
151    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
152    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
153    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
154      + internal_wave (shift in writing cg2d_ini_res)
155    checkpoint54a_pre
156    
157    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
158      - modified verification/lab_sea and natl_box_adjoint accordingly
159    
160    checkpoint54
161    checkpoint53g_post
162    o prepare splitting of thermodynamics: store convect.counter in common block
163    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
164      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
165    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
166    o new parameter "nShapS": allow to treat differently S from T (nShapT)
167    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
168    o restore adjointability
169    
170    checkpoint53f_post
171    o modifications that affect AIM experiment results (update output.txt):
172      - no advection of S at top interface Nr (pkg/generic_advdiff)
173      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
174    o AIM pkg:
175      - include stability function into surf.Flux derivative relative to Tsurf
176      - calculate clear-sky radiation & surface temp. change (for diagnostics)
177    
178    checkpoint53e_post
179    o merged cylindrical coord configuration
180    o added rotating_tank experiment
181    checkpoint53e_pre
182    
183    checkpoint53d_post
184    o faulks upgraded: re-generate output.txt that have changed:
185       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
186    o Added Bryan and Lewis, 1979, vertical diffusivity profile
187    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
188    o added Sadourny discretization of Coriolis
189      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
190      - re-enabled use of omega3 (useAbsVorticity)
191    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
192      vector-invariant equations
193      - note: does *NOT* yet use same variable visc. for no-slip BC's.
194    o recoded the lateral boundary conditions for non-hydrostatic w, this time
195      hopefully without new bugs
196      - still to do: biharmonic friction for non-hydrostatic w
197    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
198    o regenerated output for global_ocean_ebm (using -ieee)
199    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
200      of mom_common/
201      - simple re-arrangement of instructions within computing loop
202    checkpoint53d_pre
203    
204    checkpoint53c_post
205    o new version of coupler for AIM+thSIce and Ocean models
206     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
207     - land: change Evaporation of snow
208     - aim with thSIce: fix bug in snow-precip.
209    o changes to calc_gw.F
210     - bug fix for w^2 term near the bottom boundary
211     - (hopefully) improve the lateral slip boundary condtions for use with
212        partial/looped cells
213      - because the bug fix changes two verification experiments anyway (exp5
214        and plume on slope), change the lateral boundary condition from half slip
215        to the value of no_slip_sides
216    o ebm package wasnt quite up to the parallel task. Fixed that.
217    o Adjoint of EBM package + verification
218      * TLM OK
219      * ADM not sufficient accuracy yet (needs further testing)
220    
221    checkpoint53b_post
222    o Commiting new energy balance model to repository
223      * package is pkg/ebm
224      * verif. is verification/global_ocean_ebm
225      * references are in ebm_driver.F
226    C      * X. Wang, P. Stone and J. Marotzke, 1999:
227    C        Global thermohaline circulation. Part I:
228    C        Sensitivity to atmospheric moisture transport.
229    C        J. Climate 12(1), 71-82
230    C      * X. Wang, P. Stone and J. Marotzke, 1999:
231    C        Global thermohaline circulation. Part II:
232    C        Sensitivity with interactive transport.
233    C        J. Climate 12(1), 83-91
234    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
235    C        Destabilization of the thermohaline circulation
236    C        by atmospheric eddy transports.
237    C        J. Climate 7(12), 1870-1882
238    o Will need long integration testing.
239    checkpoint53b_pre
240    
241    o created pkg/mom_common in preparation for variable viscosity code
242    o renamed and split ini_mnc_io
243    o pkg/land: only liquid water can diffuse or run-off
244    o AIM using land: soil wetness availability account for snow
245    o added printMapIncludesZeros to EEPARMS namelist
246    
247    checkpoint53a_post
248    o restore TAMC compatiility for exf_constants.h
249      (no usage of _d in .h)
250    o Additional storing in KPP in an attempt to fix
251      TAMC problem with adjoint of KPP code.
252      (no success...)
253      Identical code works fine with TAF.
254    o Fixed verification/natl_box_adjoint experiments.
255      Initial conditions for Experiments 4 and 5 are now
256      set to "SEAICE_initialHEFF=0", which is more reasonable,
257      and hence gives results closer to that of Experiment 2.
258      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
259    
260    checkpoint53
261    o stable checkpoint with up to date adjoint
262      TLM tests only run for 1st grdchk at the moment. Its unclear if
263      this is a code problem or a problem with resetting code for g_
264      variables that is being autogenerated wrong.
265      Otherwise:
266       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
267       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
268         are both still in chaos following their security messes.
269    
270    checkpoint52n_post
271    o various build (mostly genmake2) changes including:
272      - ability to build/run more easily within Cygwin and MacOS X
273      - more complicated Makefiles with a stronger dependence on Gnu Make
274    o pkg/seaice modifications
275      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
276        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
277        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
278      - changed proxy for geostrophic velocity and updated
279        verification/lab_sea/results/* accordingly
280      - removed ADI dynamic solver from pkg/seaice
281      - replaced all occurrences of 1/CSTICE or 1/CSUICE
282        they caused a segmentation fault under certain circumstances
283      - removed unused field WATR
284    o bug fix in exf-package:
285      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
286         now reflect that.
287    o small fixes in the cal-package:
288      - set reference date to first of January for the 'model'-calendar
289      - failing of cal_CheckDate in cal_FullDate now actually results in a
290        warning
291    o small modifications in exf-package to increase flexibility:
292      - change climtempfreeze from a constant to a runtime parameter that
293        is specified in data.exf_clim (default = -1.9)
294      - introduce runtime parameter windstressmax (default = 2.0) that is
295        specified in data.exf
296    o fix in pkg/thsice:
297      - update Evap (Tsf changes) to be consistent with Latent heat flux
298      - maintain snow precipitation unchanged (even if Tsf >=0).
299     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
300    
301    checkpoint52m_post
302    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
303      this does not change any of the results, because myIter=0 in swfrac always
304      lead to jwtype=2 (the default anyway), but the call makes little sense
305      as a default
306    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
307    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
308      atmospheric model (AIM) to use it ; add a "slab ocean" component.
309    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
310    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
311    o extending useSingleCpuIO option to work with new exch2 I/O format
312      - old-style, missing-tile I/O is still accessible by defining CPP
313        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
314    o monitor package can write to NetCDF files and/or STDOUT
315    o fix re-definition bug in MNC_GRID_INIT_ALL()
316    o doc/api_reference added
317      - a framework for building an API Reference Manual using all
318        the "protex" comments embedded in the code
319      - see pkg/generic_advdiff, pkg/mnc for examples
320    o MNC:
321      - make myThid the last argument for all subroutines
322      - new default for the grid files: NO halos
323      - add useMNC and other run-time flags
324      - separate per-file-group handling of the unlimited dimension
325      - early initialization of MNC w/ flags read at the eeboot stage
326        and lookup tables set in initialize_fixed
327      - write all MNC output to a freshly-created directory
328    o thermodynamics sea-ice (thsice) is now tested with testreport.
329    o test exp. advect_cs: use the standard cs32 grid ; update output.
330    o Added functionality to grdchk:
331      pick global i,j,k position (or nearest wet) where to perform check.
332    
333    checkpoint52l_post
334    o new land formulation:
335      a) use ground enthalpy as prognostic variable to ensure exact
336         energy conservation.
337      b) account for water temperature and for latent heat of freezing
338         in all processes (rain, run-off, ground storage)
339      c) compute surface and ground temperature implicitly.
340    o aim_v23 modification for new land model:
341      a) Treat separately land / ocean / sea-ice surface fluxes
342         to allow implicit computation of land & sea-ice surface temp.
343      b) add snow precipitation.
344    checkpoint52l_pre
345    
346    o fix problem (when 1 tile is empty) in min/max monitor.
347    o fix bug in timeAve (u,vZetatave in common block)
348    o no restoring terms under ice for pkg/seaice
349    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
350    o bug fix for pkg/seaice pickups
351    o change MNC call locations and add coordinate attributes
352    o mask vorticity at the corner ; affects global_ocean.cs output
353    o fix ini_curvilinear_grid ; test CS experiments with mpi
354    o aim.5l_cs: modify sea-ice fraction input file ; update output
355    o exf: Adding simple range check routine for exf fields after read
356    
357    checkpoint52k_post
358    o removed top-level directory "diags"
359      - we migrated these functions to pkg/timeave a long time ago
360    o fixed bug introduced in pkg/monitor
361    o accuracy ctrlprec = 32 insuffient for gradient checks using
362      averaged fields (I/O via cost_averages)
363      -> use ctrl.h in active_file*.F to control I/O precision.
364    o paramter list of CALL ADTHE_MAIN_LOOP
365    o added initial do_the_model_io to ecco
366    o set all ...Freq to zero after cost_final
367      taveFreq, dumpFreq, pChkptFreq
368    o MAIN and ECCO differentiability restored
369    
370    checkpoint52j_post
371    o fix nchklev in tamc.h for global_ocean...
372    o Bringing flow and store directives up-to-date
373    o Really weird thing!
374      call do_the_model_io from the_main_loop with parameters
375      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
376      TAF places a faulty re-call of initialise_varia
377      after cost_final call which should not be there!
378    checkpoint52j_pre
379    
380    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
381      error messages
382    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
383    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
384      debug output
385    o modfied mdsio_writefield.F to handle non-global files under exch2
386    o update AIM Cubed-Sphere exp (aim.5l_cs):
387      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
388    o update AIM Equatorial Channel exp:

422      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
423    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
424      to work with implicit vertical advection and AB ;
425    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
426    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
427     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
428    checkpoint52e_pre
429    
430    o fix bug in impldiff when Nr=1 or Nr=2.
431    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
432    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
433    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2

445    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
446    o changes to permit hi-res, cubed-sphere, configuration
447      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
448      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
449      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
450        of surface winds for the cube
451      (A verification experiment, based on global_ocean.cs32x15, but with
452       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
453       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
454       complete with example surface forcing files and matlab scripts to look
455       at the output and compare it with that of global_ocean.cs32x15.)
456    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
457       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
458       to conform to the common rule.
459    o check-in the first version of the coupler + interfaces for multi-components
460       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
461       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
462       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
463       - ocean and atmos. share the same horizontal grid (no interpolation).
464       - exchanges between component and coupler is done in forward_step
465    o new verification experiment, cpl_aim+ocn:
466       coupled ocean - AIM atmosphere on cs32 grid.
467    
468    checkpoint52d_pre
469    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
470    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
471    
472    checkpoint52c_post
473    o Fixing OPTIONS files for use of exf:
474      - ALLOW_ECCO not needed
475      - ECCO_CPPOPTIONS.h should not be included from
476        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
477        as has been the case in the past
478      - All cal/exf related options are currently set in
479        single header file. Should remain so until we
480        agree on a consistent new policy.
481    o Removed all CPP options for cal package.
482      cal has no more CPP options.
483    o modified STOREs in GAD_ADVECTION
484    o corrected key comp. for passkey
485    
486    checkpoint52b_post

489     - modify fluxes but do not change theta directly;
490     - light cleaning of bulk_force pkg (still needed with thsice).
491     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
492       + output_thsice.txt to test thsice & bulk_force pkgs.
493    o put back grid & coriolis monitor output.
494    checkpoint52b_pre
495    
496    o call "do_the_model_io" at the beginning (=> dump initial state)
497    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
498    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
499      (need info on NUMBER_OF_PTRACERS)
500    o missing PTRACERS headers in some routines
501    o default tamc.h in pkg/autodiff supposed to crash
502      to ensure proper customization
503    
504    checkpoint52a_post
505    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
506      - moved surfaceTendencyTice from pkg/seaice to main code
507      - subroutine FREEZE_SURFACE now limits only surface temperature
508        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
509        => new output.txt for global_ocean.cs32x15 & global_with_exf
510      - keep the old version of FREEZE for backward compatibility;
511        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

520    o some bug fixes for #undef REAL4_IS_SLOW
521    
522    checkpoint52 = ecco_c52_e35
523    o after testing adjoints of checkpoint51u_post
524    
525    checkpoint51u_post
526    o this is the post-merge tag of the ecco-branch
527      (needs another clean checkout and re-testing)
528    o various natl_box_adjoint configs and results
529      but no input fields
530    o obcs adjoint not yet merged!
531    o adding ECCO global 1x1 and 2x2 degree configs
532    o updated/extended some store directives for seaice
533    o pkg/ecco now containes ecco-specific part of cost function

535      supersede those in model/src/
536      previous input data.cost now in data.ecco
537      (new namelist ecco_cost_nml)
538    o in ctrl/ cleaned some cross-dependencies and updated CPP options
539    
540    checkpoint51t_post
541    o this is the pre-merge tag of the ecco-branch
542    
543    checkpoint51s_post
544    o cleanup: removed various obsolete #define-s
545    o pkg/grdchk
546      - renamed 'ph-grd 3' to 'grad-res'
547      - merged from ecco-branch
548        (remaining bug fixes for obcs gradient checks)
549      - additional high-precision output for testreport
550        (grep for 'precision_grdchk_result')
551    
552    checkpoint51r_post
553    o cleaned up or removed CPP_OPTIONS.h files
554    o updated results for some of the tests to reflect the new
555      optfiles (-ieee: -O0 instead of -O3)
556    
557    checkpoint51q_post
558    o cd_code:
559      - moved cd_scheme.F -> cd_code_scheme.F

570      - confined inclusion of AD_CONFIG.h to where necessary.
571    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
572    
573    checkpoint51p_post
574    o create initial cd_code package
575      - WARNING: the initialization of fields within packages
576        is broken because INI_FIELDS (where READ_CHECKPOINT is
577        called) is called *before* PACKAGES_INIT_VARIABLES.
578        This seems to be backwards since
579        1) its important to initially zero the entire field including
580           the "halo" region
581        2) zeroing needs to be done *before* reading pickup info
582           and the pickup call might or might not happen in any
583           particular run
584      - this needs an overhaul for R2
585    o cleanup verification/*/code/GMREDI_OPTIONS.h
586    o cleanup testreport
587

623         global_ocean.cs32x15, and global_with_exf)
624    o added surface flux output variables to TIMEAVE_STATVARS
625    
626    checkpoint51n_pre
627    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

806    
807    checkpoint50f_post
808    o exf totally restructured
809      - replaced all exf_set_ routines by one generic exf_set_gen.F
810        and made sure it's still differentiable
811      - split exf_getffields.F into new exf_bulkformulae.F
812      - exf_inscal_/exf_outscal_ suffixes consistent with field names
813      - updated adjoint/makefile and relevant verif. accordingly
814    
815    checkpoint50f_pre
816     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
817          + change Evap over land. (update aim.5l_cs output)
818     o added missing .cvsignores and made uniform across expts
819     o changed configuration of tidal_basin_2d expt
820     o added pkg/debug functions for tracing code in fatal crashes
821     o tidied pkg/monitor to use MONITOR_OPTIONS.h
822     o new fn in pkg/monitor to stop model if solution grows too big
823     o removed lots of single quotes from comments
824    
825    checkpoint50e_post
826    o make KPP work with PTRACERS
827     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
828       nearly a copy of kpp_transport_s
829     - there is no analogue to SurfaceTendencyS, so I have to use
830       gPtr(of the surface layer) instead
831    o add a new platform SunFire+mpi (SunFire 15000) to genmake
832    checkpoint50e_pre
833    
834    checkpoint50d_post
835    o change kpp output from multiple-record state files to single-record state
836      files analogous to write_state.F
837    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
838      analogous to the cg2d-related output.
839    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
840      so that writing to internal file fn (with length 512) fails.
841    checkpoint50d_pre
842    
843    checkpoint50c_post
844    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
845    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
846    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
847    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
848    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
849    
850    checkpoint50c_pre
851    Merging from release1_p13:
852    o bug fix for pkg/seaice dynamic solver
853    o Added SEAICE_initialHEFF to pkg/seaice
854    
855    checkpoint50b_post
856    o store u*,v* in gU,V instead of in guNm1,gvNm1
857    o in order to put the momForcing out of the Adams-Bashforth:
858      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
859      to timestep.F
860    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
861    o re-generate output for highly sensitive test-exp:
862       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
863    
864    checkpoint50b_pre
865    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
866    o corrected CPP option mismatch in exf_Bulk... functions for case
867      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
868    
869    checkpoint50a_post
870    o Bug fix for merging between c50 and KPP.
871      ikey was passed from thermodynamics to kpp_calc via
872      common block rather than being recomputed in kpp_calc,
873      in contradiction with new key itdkey.
874      New key ikppkey created, and tamc.h headers updated.
875    
876    checkpoint50
877    - 2nd step of merge with ecco-branch:
878      merge changes in ecco-branch back into main trunk
879    - bug fix in find_alpha
880    - more storing in gmredi_calc_tensor.F, kpp_routines.F
881    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
882    - merged some sliced AD support routines
883    
884    checkpoint49
885    merged from ecco-branch:
886    o exf:
887      - Enable initialisation of forcing fields to constant
888        (runtime) values.
889      - in exf_getffields.F
890        Reduce i-/j-loop to interior domain, discarding overlaps.
891        That also fixes wrong TAF-key computations for key_1, key_2
892        with bulf formulae.
893      - exf_init.F modify #ifdef for exf_init_evap
894      - exf_getffieldrec.F, ctrl_getrec.F
895        The following INT-usages are not safe:
896          fldsecs  = int(fldsecs/fldperiod)*fldperiod
897          fldcount = int(fldsecs/fldperiod) + 1
898        and were modified.
899    o autodiff: checkpoint_lev...
900      - updated storing for bulk formulae (some arrays were missing)
901      - added state for seaice package
902      - synchronized with main branch
903    o DIVA:
904      Modif.s in
905      - the_main_loop.F
906      - the_model_main.F
907      and added cost_final_restore.F cost_final_store.F
908      o With these changes, it is possible to fully separate
909        the first forward run to compute the cost function (mdthe_main_loop)
910        and adjoint runs over individual DIVA intervals (adthe_main_loop)
911        into separate model executions.
912        This enables better tuning of DIVA to given queue sizes.
913      o Loss of cost function value in consecutive DIVA runs is
914        fixed by storing to 'costfinal' file.
915      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
916        beginning/end of adjoint integration is accounted for.
917      The current changes apply to TAF-1.4.26.
918      TAF has one remaining bug, requiring one manual change
919      (see MITgcm manual).
920    o cal: synchronized between MAIN and ecco-branch
921    
922    checkpoint48i_post
923    o Changes to restore differentiability of code w.r.t. previous tag
924      (mostly adding new routines to make list and replacing
925      pressure by totPhiHyd).
926    o Updated and merged grdchk package
927      - has both ADM and TLM checks
928      - works for single- and multi-proc.
929      - output cleaned
930      - worked successfully for parallel DIVA
931    o genmake:
932      - Adding -platform=SP4
933      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
934    o Modif. for DIVA:
935      ctrl_unpack should not be called in intermediate DIVA interval.
936      (similar thing would apply for active files such as
937      tbar, sbar, psbar, which should not be reinitialised;
938      only relevant for ecco-branch)
939    
940    checkpoint48h_post
941    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
942    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
943    o Added SEAICE_initialHEFF to pkg/seaice
944    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
945    
946    checkpoint48g_post
947    --- EOS:
948    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
949      store total Potential in totPhyHyd for diagnostics & EOS.
950    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
951    --- Pressure/geopotential gradient:
952    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
953    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
954      ( changes results of global_ocean_pressure )
955    o NLFS + z-coord.: add eta*Rho' contribution.
956    o accurate phiHyd when using interface-W at the middle between 2 centers
957     ( changes results of ideal_2D_oce )
958    o includes r* 2nd term in potential gradient.
959    
960    checkpoint48f_post
961    Merging from release1_p12:
962    o Modifications for using pkg/exf with pkg/seaice
963      - improved description of the various forcing configurations
964      - added basic radiation bulk formulae to pkg/exf
965      - units/sign fix for evap computation in exf_getffields.F
966      - updated verification/global_with_exf/results/output.txt
967    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
968      (SBO) core products, including oceanic mass, center-of-mass,
969      angular, and bottom pressure (see pkg/sbo/README.sbo).
970    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
971      to avoid negative values in shallow regions.
972      - updated verification/natl_box/results/output.txt
973      - updated verification/lab_sea/results/output.txt
974    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
975    o Added useSingleCpuIO option (see PARAMS.h).
976    o Updated useSingleCpuIO option in mdsio_writefield.F to
977      work with multi-field files, e.g., for single-file pickup.
978    o pkg/seaice:
979      - bug fix in growth.F: QNET for no shortwave case
980      - added HeffFile for specifying initial sea-ice thickness
981      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
982    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
983      kpp_transport_t.F, forward_step.F, and the_main_loop.F
984    o pkg/seaice:
985      - adjoint-friendly modifications
986      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
987    
988    checkpoint48e_post
989    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
990    o dynamics: change definition of computational domain & adapt mom_fluxform
991      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
992    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
993        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
994        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
995        global_ocean.90x40x15 global_with_exf global_ocean_pressure
996        inverted_barometer solid-body.cs-32x32x1
997      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
998    
999    checkpoint48d_post
1000    o in preparation for r*:
1001     a) use pre-computed gradient of hydrostatic potential:
1002        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1003     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1004        => affects results of glob_oce_pressure (different truncation error)  
1005      update output.txt of ideal_2D_oce & global_ocean_pressure
1006    
1007    checkpoint48d_pre
1008    o in preparation for r*:
1009      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1010      pass the 2 comp. of the grad. as arguments to momentum S/R.
1011      but for the moment, only used if it does not change the results.
1012    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1013    
1014    checkpoint48c_post
1015    Modifications in treatment of initial flux forcing controls
1016    to avoid extra storing of flux fields.
1017    
1018    checkpoint48c_pre
1019    o Added tidal_basin_2d experiment (currently 1D!)
1020    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1021    
1022    checkpoint48b_post
1023    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1024     (modification to pressure gradient not yet implemented)
1025    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1026      (for U & V) that are used for vertical advection of momentum.
1027    
1028    checkpoint48a_post
1029    o In preparation for r*, use temp. array to compute vertical transport
1030       in flux-form momentum pkg. => change results of few test-exp.
1031      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1032                        lab_sea, natl_box & plume_on_slope
1033    
1034    checkpoint48
1035    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1036    
1037    checkpoint47j_post
1038    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1039    o moved adexch from forward_step to addummy_in_stepping
1040    o added exch in ctrl_map_...
1041    o aveFreq.=0. at end of cost_final to avoid overwrite in
1042      reverse checkpointing loop
1043    o Yet more changes in gmredi:
1044      * adgmredi_calc_tensor
1045        avoiding all recomputation of gmredi_slope_limit
1046      * adgmredi_x/y/rtransport
1047        added flag for excessive storing to avoid recomp. of
1048        u/v/rtans, dTdx/y/z
1049        -> this is not really necessary and very memory-consuming
1050      * adgmredi_slope_psi:
1051        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1052      * gmredi_slope_limit
1053        re-activated full calculation of taperfct for case 'ac02'
1054    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1055    
1056    checkpoint47i_post
1057    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1058    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1059      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1060    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1061    o gmredi: fix few bugs.
1062    
1063    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1064    This will be a good checkpoint to plug into the ecco-branch.
1065    o few modif.'s to get latest version adjointed
1066      (mainly kick out code in ini_linear_phisurf)
1067    o modif's to run adjoint with exactConserv
1068    o case GM_BOLUS_ADVEC should be cleaned
1069      S/R gmredi_slope_psi should be cleaned
1070    o verification/carbon now has exactConserv=.TRUE.
1071    
1072    checkpoint47g_post
1073    o time-average AIM output: becomes independent from statvars time-average
1074      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1075    o After TAF bug fix:
1076      Tested adjoint of gmredi package.
1077      Tests were done with checkpoint47 rather than with latest
1078      checkpoint47f_post since the latter is broken for the adjoint
1079      verification/carbon/ contains both ADM and TLM gradient checks.
1080    Here they are, before they get changed/lost/stolen.
1081    Mostly modif.'s to fix numerical sensitivities.
1082    Gradient checks OK for
1083    - GM_taper_scheme:
1084      * clipping
1085      * ac02
1086      * linear
1087      * glw91
1088      * dm95
1089      * ldd97
1090    - GMREDI_OPTIONS:
1091      * GM_VISBECK_VARIABLE_K
1092      * GM_NON_UNITY_DIAGONAL
1093      * GM_EXTRA_DIAGONAL
1094      * GM_BOLUS_ADVEC
1095    in conjunction with data.gmredi parameters to be checked in
1096    in a few minutes under verification/carbon/code/
1097    
1098    checkpoint47f_post
1099    Merging from release1_p10:
1100    o modifications for using pkg/exf with pkg/seaice
1101      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1102        and SEAICE_EXTERNAL_FLUXES
1103      - pkg/exf CPP options EXF_READ_EVAP and
1104        EXF_NO_BULK_COMPUTATIONS
1105      - usage examples are Experiments 8 and 9 in
1106        verification/lab_sea/README
1107      - verification/lab_sea default experiment now uses
1108        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1109    
1110    checkpoint47e_post
1111    o created a tag prior to creating a branch
1112    
1113    checkpoint47d_post
1114    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1115      at the bottom boundary had an erroneous half slip boundary condition
1116    o added bottom drag and no slip boundary condition capabilities to
1117      oceanic pressure coordinates code
1118    o added new verification experiment global_ocean_pressure, this experiment is
1119      also described in the tutorial section of the manual
1120    checkpoint47d_pre
1121    
1122    checkpoint47c_post
1123    o Added a verification experiment for a global cubed-sphere ocean run
1124      -  verification/global_ocean.cubed32x32x30
1125      -  uses pkg/therm_seaice and pkg/bulk_forcing
1126    
1127    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1128    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1129      when using P-coordinate; only implemented for atmospheric config.
1130    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1131      NOTES: requires option NONLIN_FRSURF to be "#define".
1132    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1133    
1134    checkpoint47b_post
1135    Merging from release1_p9:
1136    o pkg/seaice
1137      - removed GOTO's and added taf directives
1138      - double precision constants to reduce the g77 (Linux)
1139        to F77 (SGI) differences reported in release1_p8
1140    o tools/genmake
1141      - added SGI options
1142    o verification/testscript
1143      - updated to that of checkpoint47a_post
1144    o verification/global_ocean.90x40x15/input/eedata
1145      - modified for SGI f77 compatibility
1146    o verification/lab_sea
1147      - added description of sea-ice model
1148      - added missing matlab routines
1149      - added test of thermodynamics parallelization
1150    
1151    checkpoint47a_post
1152    o new pkg: aim_v23
1153     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1154       for now, keep the same surface forcing as before.
1155     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1156     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1157     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1158    o add diagnostic of surface correction term in monitor output
1159    
1160    o bulk_force and therm_seaice
1161    - Two packages:  bulk_force (Bulk forcing)
1162      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1163    - Earlier integration from Stephaine Dutkiewicz
1164      and Patrick Heimbach.
1165    - Two ifdef statements for compile time,
1166       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1167    
1168    checkpoint47
1169    differentiable version of checkpoint46n_post
1170    o bug fix in quasihydrostaticterms
1171    o * "clean" adjoint code (in terms of extensive recomputations)
1172        can now be obtained for all GMREDI options (i.e. for
1173        - GM_VISBECK_VARIABLE_K
1174        - GM_NON_UNITY_DIAGONAL
1175        - GM_EXTRA_DIAGONAL
1176        - GM_BOLUS_ADVEC )
1177      * However, wrong gradient check problem remains unsolved.
1178      * New CPP options have been introduced for different
1179        tapering schemes
1180    o external_fields_load now part of differentiation list
1181    o pressure needs multiple storing;
1182      would be nice to have store_pressure at beginning or
1183      end of forward_step, e.g. by having phiHyd global (5-dim.)
1184      (NB: pressure is needed for certain cases in find_rho,
1185      which is also invoked through convective_adjustment).
1186    o recomputations in find_rho for cases
1187     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1188    o #define ATMOSPHERIC_LOADING should be differentiable
1189    o ini_forcing shifted to begining of initialise_varia
1190    o Incorporating QNVS line search routines into MITgcm
1191      (this is separate code, and therefore not under pkg)
1192      lsopt/, optim/
1193    o Updated verification/carbon/
1194      - #define GM_VISBECK_VARIABLE_K
1195      - GM_taper_scheme    = 'ldd97'    
1196    
1197    checkpoint46n_post
1198    Merging from release1_p8:
1199    o verification/natl_box:
1200      updating new external_fields_load routine
1201    o New package: pkg/seaice
1202      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1203      The sea-ice code is based on Hibler (1979-1980).
1204      Two sea-ice dynamic solvers, ADI and LSR, are included.
1205      In addition to computing prognostic sea-ice variables and diagnosing
1206      the forcing/external data fields that drive the ocean model,
1207      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1208      The implied surface heat flux is then stored in variable
1209      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1210      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1211      non-local transport term.  Because this call precedes model
1212      thermodynamics, temperature under sea-ice may not be "exactly" at
1213      the freezing point by the time theta is dumped or time-averaged.
1214      N.B.: fairly large differences in accuracy occur across
1215            different platforms/compilers; comparison between
1216            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)

1225    o GAD:
1226      - generated new common blocks to account for call of
1227        same gad routines with differing traceridentities
1228        (needed to modify tracerIdentity indices in GAD.h)
1229      - generated separate common blocks for case useCubedSphereExchange
1230        (Department of Futurology)
1231      - parameter lists to gmredi_?transport: added tracerIdentity
1232      - added new key indices to tamc.h
1233    o external_fields_load:
1234      - added this routine to TAF list
1235      - needed to make some common blocks global and additional storing
1236        along the same lines as exf package (checkpoint_lev?_directives.h)
1237    o exf:
1238      updated external forcing package
1239      - bug fixes carried over from ecco-branch
1240        (missing OBCS_OPTIONS.h in two routines)
1241      - enable easy to use "no forcing".
1242      - added exf I/O for atmospheric loading
1243      - added exf I/O for runoff data
1244      - transfered scaling between exf <-> MITgcm to exf namelist
1245    o Adding new verification experiment global_with_exf.
1246      This verification experiment is almost identical to the
1247      global_ocean.90x40x15 experiment, except that it uses
1248      the exf (and cal) package instead of the
1249      external_fields_load routine (cf README file).
1250    
1251    checkpoint46m_post
1252    o modified testscript to return -- when there are no lines of "%MON" output
1253    o added new flag "quasiHydrostatic" for QH mode
1254      and new routine quasihydrostaticterms()
1255    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1256      New routine: mom_u_coriolis_nh()
1257    o fixed sign of non-hydrostatic metric terms in u and v equations.
1258      Depend on correct sign of gravitySign.
1259    o added work.pc* to .cvsignore in aim directories using ifc
1260    o introduced flag for controllin non-hydrostatic metric terms
1261    o removed gravitySign from PARM04
1262    o switched to g77/ifc from pgf77 in aim experiments
1263    
1264    checkpoint46l_post
1265    o made convective adjustment work with pressure coordinates:
1266     - changed the direction of k-loop in convective_adjustment.F for the
1267       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1268     - adjusted the reference pressure k-index in convective_adjustment.F
1269     - adjusted the convection condition in convect.F (in analogy to
1270       calc_ivdc.F)
1271     - convective_adjustment no longer computes anything on the halos
1272     - removed the warnings about negative salinity from find_rho.F and
1273       find_alpha.F; instead the new routine look_for_neg_salinity, called
1274       at the beginning of find_rho, find_alpha, and find_beta, does a
1275       check of the entire slice, if CPP-option
1276       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1277    checkpoint46l_pre
1278    
1279    checkpoint46k_post
1280    o fixed the verification/global_ocean.90x40x15 experiment:
1281     - new bathymetry (the world according to A., JMC, and M.)
1282     - new initial fields and forcing fields (*.bin files)
1283     - new POLY3.COEFFS (for the next release one should switch to a full
1284       equation of state: JMD95P or MDJWF)
1285     - fixed several errors and redundancies in the data file
1286     - experiment uses looped cells
1287     - added matlab directory with diagnostic scripts for plotting of output
1288    
1289    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1290     - read AIM physics parameters from a file (data.aimphys)
1291     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1292    
1293    checkpoint46j_post
1294    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1295    o move wVel computation at the end of the time step, in S/R integr_continuity
1296    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1297    o update timeave pkg for wVel diagnostic.
1298    checkpoint46j_pre
1299    
1300    checkpoint46i_post
1301    o Clean up AIM package (and keep the results unchanged):
1302      include CPP_OPTION and use IMPLICT NONE in all routines ;
1303      declare all the variables _RL ; use _d 0 for all numerical constants.
1304      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1305    
1306    checkpoint46h_post
1307    o cleaned up the use of rhoNil and rhoConst.
1308      - rhoNil should only appear in the LINEAR equation of state, everywhere
1309        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1310        and the dynamical equations are all divided by rhoConst
1311    o introduced new parameter rhoConstFresh, a reference density of fresh
1312      water, to remove the fresh water flux's dependence on rhoNil. The default
1313      value is 999.8 kg/m^3
1314    o cleanup up external_forcing.F and external_forcing_surf.F
1315      - can now be used by both OCEANIC and OCEANICP
1316    checkpoint46h_pre
1317    
1318     Added code to convert surface volume flux (fresh water) into
1319     a mass flux when using P coordinates in the ocean (OCEANICP).
1320     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1321    
1322    checkpoint46g_post
1323    o Include a new diagnostic variable phiHydLow for the ocean model
1324      - in z-coordinates, it is the bottom pressure anomaly
1325      - in p-coordinates, it is the sea surface elevation
1326      - in both cases, these variable have global drift, reflecting the mass
1327        drift in z-coordinates and the volume drift in p-coordinates
1328      - included time averaging for phiHydLow, be aware of the drift!
1329    o depth-dependent computation of Bo_surf for pressure coordinates
1330      in the ocean (buoyancyRelation='OCEANICP')
1331      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1332        Theta, Salinity, and Pressure in the parameter list. This routine is
1333        presently contained in find_rho.F. This routine does not give the
1334        correct density for 'POLY3', which would be a z-dependent reference
1335        density.
1336    o cleaned up find_rho
1337      - removed obsolete 'eqn' from the parameter list.
1338    o added two new verification experiments: gop and goz
1339      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1340    checkpoint46g_pre
1341    
1342    checkpoint46f_post
1343    o Enable tangent linear (forward mode) gradient checks:
1344      - extended active file handling to g_... files
1345      - added TANGENT_SIMULATION to theSimulationMode
1346      - extended grdchk package accordingly
1347    o added tangent linear setup in verification/carbon/code_ftl
1348    o added adjoint setup in verification/front_relax/code_ad
1349    
1350    checkpoint46e_post
1351    o Added new equation of state -> MDJWF
1352      - EOS of McDougall et al., 2002, JAOT, submitted
1353      - caveat: the equation of state is only valid for a smaller (more
1354        realistic?) range of values than JMD95P/Z and UNESCO
1355      - added masks to the calculation of pressure in store_pressure
1356      - added more check values for density in check_eos (ini_eos.F), some of
1357        the old check values are out of the range of the MDJWF-eos, so don't
1358        expect perfect matches for those
1359    checkpoint46e_pre
1360    
1361    checkpoint46d_post
1362    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1363      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1364      case of pressure coordinates. eosType='JMD95Z' in
1365      combination with buoyancyRelation='OCEANICP' now causes an error.
1366    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1367      in find_alpha/beta.
1368    checkpoint46d_pre
1369    
1370    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1371      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1372    
1373    checkpoint46c_post
1374    o Changes necessary for ocean in p-coordinates
1375     -  Added new buoyancy relation = 'OCEANICP'
1376     -  Added new parameters = gravitySign (this used to be contained inside
1377        the factor dRdZ which I added when we first switched to R coordinates).
1378     X GM/Redi is not compatible (yet)
1379     X bottom drag and no-slip need to be debugged.
1380    checkpoint46c_pre
1381    
1382    checkpoint46b_post
1383    o Added new equation of state -> JMD95Z and JMD95P
1384      - EOS of Jackett and McDougall, 1995, JAOT
1385      - moved all EOS parameters into EOS.h
1386      - new routines ini_eos.F, store_pressure.F
1387    o Added UNESCO EOS, but not recommended because it requires
1388      in-situ temperature (see JMD95)
1389    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1390      unesco.f to be used with POLY3
1391    checkpoint46b_pre
1392    
1393    checkpoint46a_post
1394    o Added (atmospheric) pressure loading
1395      - new field in FFIELDS.h, etc...
1396      - new cpp flag ATMOSPHERIC_LOADING
1397    o Changed hFacC to _hFacC in calc_phi_hyd.F
1398    o Added SHORTWAVE_HEATING to some files for consistency
1399    checkpoint46a_pre
1400    
1401    checkpoint46
1402    further merges from release1_p5
1403    o new ctrl package
1404      - adopted from ECCO environment to enable optimization
1405      - added Eliassen Palm fluxes to controls
1406    o added Eliassen Palm flux controls to gradient check package
1407    o cost package
1408      - Compatible with new ctrl package
1409      - added Eliassen Palm cost hooks
1410      - modif's of existing cost functions
1411    o Adjoint-related bug fixes in kpp:
1412      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1413      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1414    o autodiff package
1415      - flow directives:
1416        + new for S/R do_the_model_io
1417        + enhanced for S/R checkpoint
1418        + new gmredi.flow
1419      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1420        disable adcommon.h/g_common.h by default.
1421      - fixed problem for adjoint of global_max
1422    o modified verification/carbon/
1423    o New setup for adjoint of global_ocean
1424    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1425    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1426    o incorporated hooks for sponge layer code (external_forcing.F)
1427    
1428    checkpoint45d_post
1429    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1430    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1431      (affects plume_on_slope "cg2d" output)
1432    o add new parameter deltaTfreesurf for free-surface time stepping
1433    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1434    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1435    o change phiMin in exp1 (to agree with documentation)
1436    o add new flags:
1437     - T,S forcing inside/outside Adams-Bashforth
1438     - turn off temp,salt advection and/or forcing
1439     - for each tracer, define internal flag for multiDimAdvection & A-B
1440    o monitor: change definition of KE to check conservation of Energy
1441    
1442    checkpoint45c_post
1443    o Removed f90 comments ("!")
1444    o Modified initialisations to enable exf package for MITgcm
1445      (without invoking ECCO_PACKAGE).
1446    o modifications to gradient check package (Martin Losch)
1447      - enable centered differences
1448      - modified format of standard output
1449    
1450    checkpoint45b_post
1451    o cleaned exchange calls in cg2d
1452    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1453    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1454      to configure barotropic setup (Martin Losch)
1455    o moved some initialisations within bi,bj loop in dynamics
1456      (TAF flow dependency)
1457    o in initialise_varia, moved call packages_init_variables
1458      before convective_adjustment_init
1459      (corresponding adjustment of TAF tape initialisation).
1460    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1461    
1462    checkpoint45a_post
1463    o compute Rho over the whole domain (extend iMin,jMin indices)
1464    o specific exchange for X-slice domain (case Ny=1)
1465    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1466    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1467    
1468    checkpoint44h_post = checkpoint45
1469    o Fix to restore differentiability:
1470      place at which packages_init_variables is called in
1471      initialise_varia is crucial for reverse control flow.
1472    o modifications in GMRedi to enable stable adjoint
1473      (corresponding modif's in thermodynamics, dynamics)
1474    o added missing hook for sponge layer code in external_forcing
1475    o modified test cost functions
1476    o storing in gad_advection (plus removal of write(0,*)!
1477    o missing headers TR1.h added in convective_adjustment routines
1478    o errorMessageUnit set non-equal zero in eeboot
1479      (conflict on some platforms, e.g. IBM SP3)
1480    o modified carbon verif.
1481    
1482    checkpoint44h_pre
1483    o vertical grid option: allow to put the Interface at the middle between
1484      2 cell-centers ; replace delZ in pkg/kpp by drF.
1485  o GM Advective form: Tracers are advected using the residual transport (=  o GM Advective form: Tracers are advected using the residual transport (=
1486    Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.    Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
