4      ==============================      ==============================
5    
6    checkpoint57b_post
7    o simplify options in diagnostics_fill arguments (remove weird combinations)
8    o fix MNC coordinate variables so that they now contain per-face index
9      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
10      general, EXCH2 grids are only aligned to a "local" coordinate system
11    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
12    o Implement instantaneous output within pkg diagnostics:
13      setting a negative frequency in data.diagnostics produces
14     "snap-shot" output (as opposed to time-average if freq > 0)
15    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
16      NOTE: change ptracer diagnostics name: use 2 characters to work with
17            more than 9 tracers. Add also diagnostics of advect & diffus flux.
18    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
19      becomes the coordinate variable for the 'T' dimension
20    o add CF-style coordinate variables to MNC
21      - just a first cut:  numbers are meaningless on the cubesphere and
22        missing along the T axis but otherwise it works!
23    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
24    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
25    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
26      this is based directly on what the model compute, so that the content of
27      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
28    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
29    o clean up build options files for SunOS, in particular
30      - remove -traditional from xmakedepend
31      - change -xarch=v9 to -xarch=native for f77
32      - restore use of make (not gmake)
33      - add CC=gcc if using g77
34    o changes per discussion of AM, JMC, & EH3 today:
35      - move redundant "grid" variables out of "state" -- in preparation of
36        creating proper CF-style coordinate variables and in recognition
37        that any/all grid variables can be easily copied (eg. w/NCO) from
38        the grid files into any of the other NetCDF files
39      - *always* output grid variables with MDSIO (this will eventually be
40        changed)
41      - output MNC grid file if useMNC is true
42    o every instance of _END_MASTER() has been found and replaced with
43      _END_MASTER( myThid ) in order to satisfy certain picky Sun
44      preprocessors
45    o re-arrange diagnostics pkg initialisation:
46     - allow each package to extend the available diagnostics list
47     - add some checking and fix small problems (multi-threaded, ...)
48     - new S/R diagnostics_fill (replace fill_diagnostics):
49       look through the short list of active diag. (instead of the long list)
50       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
51    
52    checkpoint57a_post
53    o this set of changes restores TAMC compatibility
54      tested for global_ocean.90x40x15 adjoint on trough
55      (what a pain)
56    
57    checkpoint57a_pre
58    o some modifs in tools/build_options for sunos
59    o call ctrl_pack for ctrl at end for optimcycle=0
60    
61    checkpoint57
62    o add horizontal bi-harmonic viscosity for vertical velocity
63      - new parameter viscA4W (defaults to viscA4)
64      - affects only non-hydrostatic code
65      - to be done: no-slip lateral boundary conditions
66    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
67    o implement Implicit Vertical advection for pTracers
68    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
69      (implemented also for implicit vertical diffusion & advection)
70    o OBCS: extend application of tracer open boundary conditions
71      to a strip beyond the boundary of width Olx/Oly
72    o add call monitor to TAF set of required calls (flow directives)
73      and include in natl_box_adjoint
74    o untangle a few ifdefs related to cost, ctrl, autodiff
75      untangel a few ALLOW_ECCO_OPTIMIZATION
76    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
77      (theta2, salt2 in ecco_cost_weights)
78    
79    checkpoint56c_post
80    o OBCS as control variables
81      - update ctrl_ad_diff.list, obcs_ad_diff.list
82      - remove balance of obcs controls from default
83      - fix index bug nobcs in ctrl_init
84      - fix dummy fields filen in ctrl_pack
85      - add dummy weights for obcs
86    o lsopt: comment out fort.94 output
87    o optim:
88      - remove unnecessary header files
89      - adjusted namelists
90      - add xerbla.F to Makefile
91    o exf:
92      - multiple modifications of exf_check_range
93      - unit change in exf_init_runoff from [m/year] to [m/s]
94    o mdsio:
95      - i/o-vector change debugLevel from debLevA to debLevB
96    
97    checkpoint56b_post
98    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
99      is called from DO_THE_MODEL_IO
100      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
101      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
102      - clean up PTRACERS_WRITE_TIMEAVE a little
103    o add another verification experiment that tests both the cfc-pkg and
104      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
105      reactive tendencies treated inline with regular timestepping
106    o testreport previously did a lousy job of comparing small numbers, so
107      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
108      implemented in the little c-progam tmp_cmpnum.c which is embedded in
109      testreport.
110    o ptracers_monitor: bug fix for MPI
111    
112    checkpoint56a_post
113    o GCHEM: finish reorganizating the package
114      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
115        (introduces another 3D-array for each passive tracer, but only if
116        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
117        gchemTendency is not needed because the timestep is done separately)
118      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
119      - GCHEM is now---more or less cleanly---separate from PTRACERS
120      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
121        so clear to me how that should be done in a general way.
122    o CFC: improve formatting of output in CFC_ATMOS
123    o PTRACERS:
124      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
125        that ALL experiments with ptracers enable can be checked. This makes
126        GCHEM_MONITOR obsolete.
127      - include a runtime parameter PTRACERS_monitorFreq that defaults to
128        monitorFreq
129      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
130    o add PTRACERS (PTR0[1-5]) to testreport output
131    o exf_check_range:
132      * default changed to .TRUE.
133      * will check values for niter0 if debLevA, every timestep if debLevB
134      * STOP in exf_check_range if 'out of range'
135      * range chosen generous to allow for potential extema
136      TBD: a version with stricter range
137           permitted range would be runtime parameters
138    o GMredi:
139      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
140      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
141      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
142    o GCHEM:
143      - move call to GCHEM_FORCING_SEP, so that it is now called before
144        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
145      - introduced a useGCHEM runtime flag and applied it everywhere.
146      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
147        this flag is now only visible within GCHEM-pkg routines.
148      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
149        be replaced by a 3D array that is computed before thermodynamics; for
150        this, the tracer ID iTracer had to be included into the parameter list
151        of ptracers_forcing
152      - set up forward_step to call gchem_forcing, that will replace
153        gchem_forcing_int in ptracers_forcing
154      - cleaning up
155    o small cleaning of exch2: remove files that are also in eesupp/src
156    
157    checkpoint56
158    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
159    o mnc: cleanup "full" files--fixes out-of-memory problem
160    o ECCO-GODAE
161      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
162      * fully merged and updated from SIO code
163        windstress sign change affects
164        - exf_inscal_[u/v]stress
165        - sign of xx_tau[u/v] adjustments
166        - signs in cost_scat
167      * ctrl_get_gen: avoid update of tau[u/v] for first few days
168      * natl_box_adjoint updated and compressed
169      * 2-level checkpoint switch added
170        (tested in EXP. 1 of natl_box_adjoint)
171      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
172    o SVD
173      * first complete, non-hacked version for SVD calculations
174      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
175        performed via direct access files admtlm_vector.it????
176        (via ctrl_[un]pack)
177      * optimcycle is used for ARPACK iteration counter
178        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
179      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
180        and add linear transforms where necessary
181      * controls are initial/final SST, SSS (can be extended; need to check
182        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
183    o mdsio: filename info to both stderr, stdout
184    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
185      from sign change
186    
187    checkpoint55j_post
188    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
189      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
190    o add consistent build directories and .cvsignore files to verification
191    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
192    o make all subroutines 30 or less characters in length for certain older
193      compilers to work (a thorough search only turns up two routines in
194      pkg/ptracers)
195    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
196      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
197    
198    checkpoint55i_post
199    o change arrays for total vertical diffusivity (2.D if explicit,
200      3.D if implicit) ; each ptracer uses its own background value.
201    o added mnc/NetCDF output capability to ocn_compon_interf
202      - added bits to verification/cpl_aim+ocn so that it can run on
203        ITRDA and other clusters without the mpirun "-wd" option
204    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
205      configuration
206    o give MNC the ability to create additional files rather than
207      exceeding a specified file size limit "MNC_MAX_FILESIZE"
208      - the default is just less than 2GB which is a practical limit
209        on many systems
210    o Compute the non-local term using either KPP vertical diffusivity (=default)
211       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
212    
213    checkpoint55h_post
214    o add verification test "vermix"
215    o remove all the *_ioinc flags and replace with the single global
216      outputTypesInclusive flag
217    o allow to set a vertical profile of vertical diffusivity for T & S
218    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
219    o useMNC moved from data.mnc to data.pkg
220    
221    checkpoint55g_post
222    o Renaming carbon AD experiments to comply with testreport conventions
223    o Updating adjoint of Held-Suarez hs94.1x64x5
224    o Fixing directives for non-ECCO forward_step, after ECCO directives
225      have been fixed to avoid recomp. of do_oceanic_phys
226      Works well for global_ocean.90x40x15,
227      but recomp. issue remains for carbon
228    o Updating adjoint output for natl_box_adjoint after
229      pkg/ecco has been modified (see taga c55d_post)
230    
231    checkpoint55f_post
232    o rename to timeave_init_fixed
233    
234    checkpoint55e_post
235    o some delicate re-shuffle of store directives to avoid one
236      extra call of do_oceanic_physics
237      affects ecco_the_main_loop.F, do_oceanic_physics.F
238      checkpoint_lev1_directives.h
239    o NB: this may break global_ocean adjoint temporarily,
240      but it is clear how to fix it. Will do later, need this now.
241    
242    checkpoint55d_post
243    o ECCO specific cost function terms (up-to-date with 1x1 runs)
244    o ecco_cost_weights is modified to 1x1 runs
245    o modifs to allow observations to be read in as
246      single file or yearly files
247    o enable to read exf forcing fields as either
248      single file or yearly files (flag useExfYearlyFields)
249    checkpoint55d_pre
250    
251    o switch between 2-level and 3-level checkpointing
252    o add ability of MNC to write local and "partial" (eg. 2D slices where
253      the full 3D field is never actually stored) arrays to NetCDF files
254      with the correct (that is, the complete multi-dimensional) set of
255      array indicies
256      - used in mom_vecinv() to write the diagFreq output
257      - tested (demonstrated) in verification/aim.5l_cs
258    o further mnc-ification
259      - add verification/lab_sea to the list with mnc setups
260      - fix undefined mnc v-names in cd_code
261      - add kpp to mnc output (both snapshot and timeave)
262    o non-hydrostatic code
263      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
264        in calc_gw.F
265      - defaults to viscAh
266      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
267        friction or Leith) in non-hydrostatic mode, as long as there is
268        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
269    o pkg/cost
270      extend simple cost functions to treat time mean quantities
271      (T,U,V) via cost_accumulate_state from cost_tile
272    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
273        be 2 times larger than the minimum size the advection scheme requires.
274        now get a perfect conservation of salt in advect_cs test-exp (updated)
275    o GGL90 (Gaspar's TKE mixed layer)
276      - add horizontal diffusion of TKE, requires exchanges in
277        do_fields_blocking_exchanges, horizontal diffusivity is zero by
278        default. In OPA there is no horizontal diffusion of TKE but the
279        mixing coefficients are computed from a horizontal average of TKE of
280        6 points or so. I think that diffusion has a little more physical
281        justification.
282      - clean up ggl90_calc in the hope of reducing memory usage (this hope
283        was in vain)
284      - mask tke-variable in ggl90_init
285    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
286    o fix biharmonic diffusion on CS-grid.
287    o more obcs stuff
288      - added obcs_external_fields_load as an alternative to the EXF-pkg option
289        for reading boundary values. This routine is called from
290        obcs_prescribe_read
291      - updated obcs_check
292      - changed sponge layer relaxation parameter units for days to seconds
293      - turned off sponge layer by default
294      - changed argument list of OBCS_CALC to myTime+deltaTclock
295      - fixed about 35 bugs in obcs_external_fields_load
296    
297    checkpoint55c_post
298    o obcs stuff
299      - new runtime flags useOBCSprescribe, useOBCSbalance
300      - re-arranged obcs_calc
301      - moved exf_getobcs to obcs_prescibe_read
302        obcs_prescibe_read is called after ORLANSKI stuff
303        and independent of it (executable can contain all).
304      - updated obcs_check
305      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
306        These may be necessary only if tangential velocities are
307        prescribed at OB, not sure, needs testing.
308    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
309      which simplifies the calls and passes the ifc check-bounds test
310    
311    checkpoint55b_post
312    o add a 2D scalar, Z location, exchange_2 routine.
313    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
314      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
315      affects advect_cs results (for the wrong reason): update output.txt
316    o use a more standard discretization for biharmonic viscosity ;
317     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
318      affects results of dome set-up: update output.txt
319    o fix gad_advection.F (CubedSphere part), back to version 1.23
320    o fix bug in mom_vi_del2uv.F (CubedSphere part).
321    
322    checkpoint55a_post
323    o merged code to
324      * prescribe/read time-dependent open boundaries
325        (works in conjunction with exf, cal)
326      * sponge layer code for open boundaries
327      * each boundary N/S/E/W now has its own CPP option
328        (healthy for the adjoint)
329    
330    checkpoint55
331    o up-to-date adjoint of previous breaks
332      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
333      - global_ocean_ebm: adjoint still needs fix (TLM ok)
334      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
335      - carbon: * remove tr1-related adjoint verification
336                * add ptracer as control variable
337    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
338      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
339    
340    checkpoint54f_post
341    o in verification/carbin/ remove experiment related to
342      ALLOW_PASSIVE_TRACER (array tr1 etc)
343      code_ad/ input_ad/ results_ad
344    
345    o add two new packages
346      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
347        + subject to optimization (memory)
348      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
349        + subject to reordering (many GOTOs in the original code)
350        + so far opps is called for every (i,j) point, and then operates in
351          the vertical; one may want to reorder the scheme in order operate in
352          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
353          fields)
354    o overhaul of IO so that we now have flags for MDSIO and/or MNC
355      - all verification tests compile and run with linux_ia32_g77
356      - defaults are compatible with current input files--nothing
357        should change if you were not previously using MNC
358      - MNC output has been added in numerous places (eg. timeave)
359        but there are still a few writes not yet do-able with MNC
360        (this is in progress)
361      - flags now allow for either/or/both use of MDSIO and MNC and
362        documentation will soon follow
363      - numerous small formatting cleanups for ProTeX
364    o add version info (via BUILD_INFO.h) to MNC and stdout
365    
366    checkpoint54e_post
367    o add two new packages
368      - pp81 (Packanowski and Philander, 1981), Richardson number and
369        stratification dependent mixing
370      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
371      - these scheme operate in a similar manner as KPP (without ghat, of
372        course), however there is only one diffusivity that is used for both
373        temperature and salinity (and passive tracers)ç
374    o add offline package
375    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
376      provided by Stephanie Dutkiewicz
377    o genmake2: add ability to search for C compilers and cleanup test output
378      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
379    
380    checkpoint54d_post
381    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
382    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
383      leading to additional shift by 5 days each year of integration
384       (i.e. leading to considerable offset over the years)
385    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
386    o start with no AB and no initial filtering (staggerTimeStep):
387      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
388    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
389      (external loading & cpl import/export stay in forward_step.F)
390    o update coupling interface to work with new staggerTimeStep
391    o change MDSIO ptracers_pickup.
392    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
393    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
394    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
395    
396    checkpoint54c_post
397    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
398      this affects (truncation error) output.txt of test-exp:
399       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
400    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
401    o change Qnet to always be the net heat flux, (+upward).
402      affects (truncation error) output of natl_box exp.: updated
403    o define the max number of passive tracers in PTRACERS_SIZE.h
404    o start to test mnc routinely in exp0
405    o add sea-ice loading (sIceLoad) as a new forcing field.
406    
407    checkpoint54b_post
408    o add testreport "-j JOBS" option for parallel builds (tested and pretty
409       impressive on Altix and Opteron systems)
410    o diagnostics can now write NetCDF files through the mnc package
411    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
412    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
413    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
414      affects (truncation error) output of lab_sea & natl_box exp.: updated
415    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
416    
417    checkpoint54a_post
418    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
419    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
420    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
421    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
422      + internal_wave (shift in writing cg2d_ini_res)
423    checkpoint54a_pre
424    
425    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
426      - modified verification/lab_sea and natl_box_adjoint accordingly
427    
428    checkpoint54
429    checkpoint53g_post
430    o prepare splitting of thermodynamics: store convect.counter in common block
431    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
432      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
433    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
434    o new parameter "nShapS": allow to treat differently S from T (nShapT)
435    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
436    o restore adjointability
437    
438    checkpoint53f_post
439    o modifications that affect AIM experiment results (update output.txt):
440      - no advection of S at top interface Nr (pkg/generic_advdiff)
441      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
442    o AIM pkg:
443      - include stability function into surf.Flux derivative relative to Tsurf
444      - calculate clear-sky radiation & surface temp. change (for diagnostics)
445    
446    checkpoint53e_post
447    o merged cylindrical coord configuration
448    o added rotating_tank experiment
449    checkpoint53e_pre
450    
451    checkpoint53d_post
452    o faulks upgraded: re-generate output.txt that have changed:
453       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
454    o Added Bryan and Lewis, 1979, vertical diffusivity profile
455    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
456    o added Sadourny discretization of Coriolis
457      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
458      - re-enabled use of omega3 (useAbsVorticity)
459    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
460      vector-invariant equations
461      - note: does *NOT* yet use same variable visc. for no-slip BC's.
462    o recoded the lateral boundary conditions for non-hydrostatic w, this time
463      hopefully without new bugs
464      - still to do: biharmonic friction for non-hydrostatic w
465    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
466    o regenerated output for global_ocean_ebm (using -ieee)
467    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
468      of mom_common/
469      - simple re-arrangement of instructions within computing loop
470    checkpoint53d_pre
471    
472    checkpoint53c_post
473    o new version of coupler for AIM+thSIce and Ocean models
474     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
475     - land: change Evaporation of snow
476     - aim with thSIce: fix bug in snow-precip.
477    o changes to calc_gw.F
478     - bug fix for w^2 term near the bottom boundary
479     - (hopefully) improve the lateral slip boundary condtions for use with
480        partial/looped cells
481      - because the bug fix changes two verification experiments anyway (exp5
482        and plume on slope), change the lateral boundary condition from half slip
483        to the value of no_slip_sides
484    o ebm package wasnt quite up to the parallel task. Fixed that.
485    o Adjoint of EBM package + verification
486      * TLM OK
487      * ADM not sufficient accuracy yet (needs further testing)
488    
489    checkpoint53b_post
490    o Commiting new energy balance model to repository
491      * package is pkg/ebm
492      * verif. is verification/global_ocean_ebm
493      * references are in ebm_driver.F
494    C      * X. Wang, P. Stone and J. Marotzke, 1999:
495    C        Global thermohaline circulation. Part I:
496    C        Sensitivity to atmospheric moisture transport.
497    C        J. Climate 12(1), 71-82
498    C      * X. Wang, P. Stone and J. Marotzke, 1999:
499    C        Global thermohaline circulation. Part II:
500    C        Sensitivity with interactive transport.
501    C        J. Climate 12(1), 83-91
502    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
503    C        Destabilization of the thermohaline circulation
504    C        by atmospheric eddy transports.
505    C        J. Climate 7(12), 1870-1882
506    o Will need long integration testing.
507    checkpoint53b_pre
508    
509    o created pkg/mom_common in preparation for variable viscosity code
510    o renamed and split ini_mnc_io
511    o pkg/land: only liquid water can diffuse or run-off
512    o AIM using land: soil wetness availability account for snow
513    o added printMapIncludesZeros to EEPARMS namelist
514    
515    checkpoint53a_post
516    o restore TAMC compatiility for exf_constants.h
517      (no usage of _d in .h)
518    o Additional storing in KPP in an attempt to fix
519      TAMC problem with adjoint of KPP code.
520      (no success...)
521      Identical code works fine with TAF.
522    o Fixed verification/natl_box_adjoint experiments.
523      Initial conditions for Experiments 4 and 5 are now
524      set to "SEAICE_initialHEFF=0", which is more reasonable,
525      and hence gives results closer to that of Experiment 2.
526      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
527    
528    checkpoint53
529    o stable checkpoint with up to date adjoint
530      TLM tests only run for 1st grdchk at the moment. Its unclear if
531      this is a code problem or a problem with resetting code for g_
532      variables that is being autogenerated wrong.
533      Otherwise:
534       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
535       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
536         are both still in chaos following their security messes.
537    
538    checkpoint52n_post
539    o various build (mostly genmake2) changes including:
540      - ability to build/run more easily within Cygwin and MacOS X
541      - more complicated Makefiles with a stronger dependence on Gnu Make
542    o pkg/seaice modifications
543      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
544        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
545        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
546      - changed proxy for geostrophic velocity and updated
547        verification/lab_sea/results/* accordingly
548      - removed ADI dynamic solver from pkg/seaice
549      - replaced all occurrences of 1/CSTICE or 1/CSUICE
550        they caused a segmentation fault under certain circumstances
551      - removed unused field WATR
552    o bug fix in exf-package:
553      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
554         now reflect that.
555    o small fixes in the cal-package:
556      - set reference date to first of January for the 'model'-calendar
557      - failing of cal_CheckDate in cal_FullDate now actually results in a
558        warning
559    o small modifications in exf-package to increase flexibility:
560      - change climtempfreeze from a constant to a runtime parameter that
561        is specified in data.exf_clim (default = -1.9)
562      - introduce runtime parameter windstressmax (default = 2.0) that is
563        specified in data.exf
564    o fix in pkg/thsice:
565      - update Evap (Tsf changes) to be consistent with Latent heat flux
566      - maintain snow precipitation unchanged (even if Tsf >=0).
567     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
568    
569    checkpoint52m_post
570    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
571      this does not change any of the results, because myIter=0 in swfrac always
572      lead to jwtype=2 (the default anyway), but the call makes little sense
573      as a default
574    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
575    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
576      atmospheric model (AIM) to use it ; add a "slab ocean" component.
577    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
578    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
579    o extending useSingleCpuIO option to work with new exch2 I/O format
580      - old-style, missing-tile I/O is still accessible by defining CPP
581        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
582    o monitor package can write to NetCDF files and/or STDOUT
583    o fix re-definition bug in MNC_GRID_INIT_ALL()
584    o doc/api_reference added
585      - a framework for building an API Reference Manual using all
586        the "protex" comments embedded in the code
587      - see pkg/generic_advdiff, pkg/mnc for examples
588    o MNC:
589      - make myThid the last argument for all subroutines
590      - new default for the grid files: NO halos
591      - add useMNC and other run-time flags
592      - separate per-file-group handling of the unlimited dimension
593      - early initialization of MNC w/ flags read at the eeboot stage
594        and lookup tables set in initialize_fixed
595      - write all MNC output to a freshly-created directory
596    o thermodynamics sea-ice (thsice) is now tested with testreport.
597    o test exp. advect_cs: use the standard cs32 grid ; update output.
598    o Added functionality to grdchk:
599      pick global i,j,k position (or nearest wet) where to perform check.
600    
601    checkpoint52l_post
602    o new land formulation:
603      a) use ground enthalpy as prognostic variable to ensure exact
604         energy conservation.
605      b) account for water temperature and for latent heat of freezing
606         in all processes (rain, run-off, ground storage)
607      c) compute surface and ground temperature implicitly.
608    o aim_v23 modification for new land model:
609      a) Treat separately land / ocean / sea-ice surface fluxes
610         to allow implicit computation of land & sea-ice surface temp.
611      b) add snow precipitation.
612    checkpoint52l_pre
613    
614    o fix problem (when 1 tile is empty) in min/max monitor.
615    o fix bug in timeAve (u,vZetatave in common block)
616    o no restoring terms under ice for pkg/seaice
617    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
618    o bug fix for pkg/seaice pickups
619    o change MNC call locations and add coordinate attributes
620    o mask vorticity at the corner ; affects global_ocean.cs output
621    o fix ini_curvilinear_grid ; test CS experiments with mpi
622    o aim.5l_cs: modify sea-ice fraction input file ; update output
623    o exf: Adding simple range check routine for exf fields after read
624    
625    checkpoint52k_post
626    o removed top-level directory "diags"
627      - we migrated these functions to pkg/timeave a long time ago
628    o fixed bug introduced in pkg/monitor
629    o accuracy ctrlprec = 32 insuffient for gradient checks using
630      averaged fields (I/O via cost_averages)
631      -> use ctrl.h in active_file*.F to control I/O precision.
632    o paramter list of CALL ADTHE_MAIN_LOOP
633    o added initial do_the_model_io to ecco
634    o set all ...Freq to zero after cost_final
635      taveFreq, dumpFreq, pChkptFreq
636    o MAIN and ECCO differentiability restored
637    
638    checkpoint52j_post
639    o fix nchklev in tamc.h for global_ocean...
640    o Bringing flow and store directives up-to-date
641    o Really weird thing!
642      call do_the_model_io from the_main_loop with parameters
643      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
644      TAF places a faulty re-call of initialise_varia
645      after cost_final call which should not be there!
646    checkpoint52j_pre
647    
648    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
649      error messages
650    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
651    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
652      debug output
653    o modfied mdsio_writefield.F to handle non-global files under exch2
654    o update AIM Cubed-Sphere exp (aim.5l_cs):
655      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
656    o update AIM Equatorial Channel exp:
657      use standard aim_v23 pkg and change the SST fields to be more realistic.
658    o globalFile now works with exch2
659    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
660      mon_vort3.F to make exch2 friendly with >1 tile per cube face
661    o limit timeave output for hi-res integrations
662    
663    checkpoint52i_post
664    o removed CPP_EEOPTIONS.h from verification/*/code
665    o updated the tiling for global_ocean_pressure
666    checkpoint52i_pre
667    
668    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
669      the old pkg/aim).
670    
671    checkpoint52h_pre
672    o shortened offending lines in exch2_send_rx?.template
673    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
674    o genmake2: add build & execute test for NetCDF code
675    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
676      old grid files, moved CPP_EEMACROS.h to pkg/exch2
677    o added useSingleCPUIO flag to monitor.F and mon_out.F
678    o added temporary hack for sea-ice dynamics on the cube:
679      metric terms are ignored and it is assumed that
680      there is no sea-ice on cube faces 1, 2, 4, and 5.
681    
682    checkpoint52f_post
683    o added exch2 cube routines to pkg/exch2
684    o modified hs94.cs-32x32x5 to use it
685    o added new grid files to hs94.cs-32x32x5
686    checkpoint52f_pre
687    
688    checkpoint52e_post
689    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
690      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
691    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
692      to work with implicit vertical advection and AB ;
693    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
694    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
695     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
696    checkpoint52e_pre
697    
698    o fix bug in impldiff when Nr=1 or Nr=2.
699    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
700    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
701    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
702      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
703    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
704    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
705    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
706    
707    checkpoint52d_post
708    o re-tiled many expts to allow comparison in multi-processor mode
709      - updated output accordingly
710      - changed hs94.128x64x5 to use intial T from file rather than use the
711        random number generator
712    o add infrastructure in model routines for fizhi and gridalt packages
713    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
714    o changes to permit hi-res, cubed-sphere, configuration
715      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
716      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
717      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
718        of surface winds for the cube
719      (A verification experiment, based on global_ocean.cs32x15, but with
720       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
721       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
722       complete with example surface forcing files and matlab scripts to look
723       at the output and compare it with that of global_ocean.cs32x15.)
724    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
725       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
726       to conform to the common rule.
727    o check-in the first version of the coupler + interfaces for multi-components
728       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
729       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
730       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
731       - ocean and atmos. share the same horizontal grid (no interpolation).
732       - exchanges between component and coupler is done in forward_step
733    o new verification experiment, cpl_aim+ocn:
734       coupled ocean - AIM atmosphere on cs32 grid.
735    
736    checkpoint52d_pre
737    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
738    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
739    
740    checkpoint52c_post
741    o Fixing OPTIONS files for use of exf:
742      - ALLOW_ECCO not needed
743      - ECCO_CPPOPTIONS.h should not be included from
744        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
745        as has been the case in the past
746      - All cal/exf related options are currently set in
747        single header file. Should remain so until we
748        agree on a consistent new policy.
749    o Removed all CPP options for cal package.
750      cal has no more CPP options.
751    o modified STOREs in GAD_ADVECTION
752    o corrected key comp. for passkey
753    
754    checkpoint52b_post
755    o new version: "thsice" of thermodynamic sea-ice pkg:
756     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
757     - modify fluxes but do not change theta directly;
758     - light cleaning of bulk_force pkg (still needed with thsice).
759     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
760       + output_thsice.txt to test thsice & bulk_force pkgs.
761    o put back grid & coriolis monitor output.
762    checkpoint52b_pre
763    
764    o call "do_the_model_io" at the beginning (=> dump initial state)
765    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
766    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
767      (need info on NUMBER_OF_PTRACERS)
768    o missing PTRACERS headers in some routines
769    o default tamc.h in pkg/autodiff supposed to crash
770      to ensure proper customization
771    
772    checkpoint52a_post
773    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
774      - moved surfaceTendencyTice from pkg/seaice to main code
775      - subroutine FREEZE_SURFACE now limits only surface temperature
776        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
777        => new output.txt for global_ocean.cs32x15 & global_with_exf
778      - keep the old version of FREEZE for backward compatibility;
779        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

791    o after testing adjoints of checkpoint51u_post
792    
793    checkpoint51u_post
794    o this is the post-merge tag of the ecco-branch
795      (needs another clean checkout and re-testing)
796    o various natl_box_adjoint configs and results
797      but no input fields
798    o obcs adjoint not yet merged!
799    o adding ECCO global 1x1 and 2x2 degree configs
800    o updated/extended some store directives for seaice
801    o pkg/ecco now containes ecco-specific part of cost function
802    o top level routines the_main_loop, forward_step
803      supersede those in model/src/
804      previous input data.cost now in data.ecco
805      (new namelist ecco_cost_nml)
806    o in ctrl/ cleaned some cross-dependencies and updated CPP options
807    
808    checkpoint51t_post
809    o this is the pre-merge tag of the ecco-branch
810    
811    checkpoint51s_post
812    o cleanup: removed various obsolete #define-s
813    o pkg/grdchk
814      - renamed 'ph-grd 3' to 'grad-res'
815      - merged from ecco-branch
816        (remaining bug fixes for obcs gradient checks)
817      - additional high-precision output for testreport
818        (grep for 'precision_grdchk_result')
819    
820    checkpoint51r_post
821    o cleaned up or removed CPP_OPTIONS.h files
822    o updated results for some of the tests to reflect the new
823      optfiles (-ieee: -O0 instead of -O3)
824    
825    checkpoint51q_post
826    o cd_code:
827      - moved cd_scheme.F -> cd_code_scheme.F
828      - separate read_checkpoint from cd_code_ini_vars.F
829      - separated cd_code part from write_checkpoint
830      - updated AD_SOURCE, generated .flow

839    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
840    
841    checkpoint51p_post
842    o create initial cd_code package
843      - WARNING: the initialization of fields within packages
844        is broken because INI_FIELDS (where READ_CHECKPOINT is
845        called) is called *before* PACKAGES_INIT_VARIABLES.
846        This seems to be backwards since
847        1) its important to initially zero the entire field including
848           the "halo" region
849        2) zeroing needs to be done *before* reading pickup info
850           and the pickup call might or might not happen in any
851           particular run
852      - this needs an overhaul for R2
853    o cleanup verification/*/code/GMREDI_OPTIONS.h
854    o cleanup testreport
855    
856    checkpoint51o_post

864    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
865    o bug fix in find_alpha.F for MDJWF:
866      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
867        change rho -> rho-rhoConst
868      - replace call find_rho to find_rhonum
869    o initialisation of rFlx extended to full array (required by TAF)
870      and shifted to thermodynamics
871    o removed PTRACERS.h in ptracers routine
872    o added surfacetendencyPtr to S/R parameter list pracers_forcing

891         global_ocean.cs32x15, and global_with_exf)
892    o added surface flux output variables to TIMEAVE_STATVARS
893    
894    checkpoint51n_pre
895    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

942      Moving pkg-specific differentiation list to corresponding pkg
943      Moving pkg-specific checkpoint-lev storing to corresponding pkg
944      ---> conventions are
945           - pkg_ad.flow
946           - pkg_ad_diff.list
947           - pkg_ad_check_lev?_dir.h
948    
949    checkpoint51i_post
950    o merge of the branch-genmake2
951      - knowingly breaks the older genmake

981    o Added on-the-fly spatial interpolation capability
982        "USE_EXF_INTERPOLATION" to pkg/exf.
983      - This is a temporary Cartesian-grid hack until
984        the super-duper ESMF coupler becomes available.
985      - See verification/global_with_exf/README for usage example.
986      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
987        flags and modified pkg/seaice accordingly.
988    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
989        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
990        non-local transport term.
991    
992    checkpoint51e_post
993    o pkg/mom_vecinv:
994      - changes related to hFac: use S/R from aim.5l_cs/code (coriolis & vort.advec)

1000    o AIM : add stratospheric drag in the upper level
1001    
1002    checkpoint51d_post
1003    o change function ILNBLNK (=> last non-blank char.) to return zero
1004      (instead of the string length) when the string. char is empty
1005    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
1006    o modif's to restore TAMC compatibility
1007      - avoid "_d" constructs in PARAMETER declarations
1008      - avoid interrupting lines by comment lines
1009    o Use cluster local disks for purely local I/O

1018      - debLevA: standard
1019      - debLevB: equivalent to current debugMode=.TRUE.
1020    o introducing pathname variable mdsioLocalDir for mdsio
1021      that can be specified at runtime
1022      (relevant for cluster I/O to local disk)
1023    `
1024    >>>checkpoint51b_post
1025    adjoint of ptracers
1026    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
1027    o extended state in checkpoint_lev?, etc.
1028    o alternative ctrl/cost with tr1 or ptracer
1029    o new comlev1_bibj_ptracers
1030    o new ptracers.flow
1031    o made ptracers_forcing same as external_forcing_s
1032    o added verification for adjoint with ptracers
1033      - adm. grdchk fail so far
1034      - tlm. grdchk OK
1035      - checked tapelev/comlev recomputations: OK
1036    <<<checkpoint51b_pre
1037    
1038    checkpoint51a_post
1039    o added code for biogeochemistry package
1040      - new pkgs: dic, gchem
1041      - new subroutine in ptracers
1042    o modify code for biogeo packages
1043      - in model/src and pkg/ptracers
1044    
1045    checkpoint51
1046    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1047      - autodiff, ctrl, exf, grdchk, seaice
1048      kept separate packages
1049      - cost, ecco, obcs
1050    o updating verification/internal_wave, verification/lab_sea
1051      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1052    
1053    checkpoint50i_post
1054    o Preparing next differentiable checkpoint and sync
1055      of MAIN vs. ecco-branch
1056      - 1st step: this one is differentiable
1057      - 2nd step: next(! not this) checkpoint will have updated packages
1058                  from ecco-branch)
1059    
1060    checkpoint50h_post
1061    o new package "land": provide surface BC for AIM.
1062    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1063    o AIM: use true log-P extrapolation for near surface temp (= as in
1064        F.Molteni paper) ; update aim.5l_cs output.
1065    o New variable in PARM03 for more flexible pickups
1066    o somewhat cleaned package initialisation sequence for
1067      ctrl/ cost/ ecco/ in packages_... routines
1068    
1069    checkpoint50g_post
1070    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1071      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1072      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1073        made the default because of faster convergence than ADI
1074    
1075    checkpoint50f_post
1076    o exf totally restructured
1077      - replaced all exf_set_ routines by one generic exf_set_gen.F
1078        and made sure it's still differentiable
1079      - split exf_getffields.F into new exf_bulkformulae.F
1080      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1081      - updated adjoint/makefile and relevant verif. accordingly
1082    
1083    checkpoint50f_pre

1091     o removed lots of single quotes from comments
1092    
1093    checkpoint50e_post
1094    o make KPP work with PTRACERS
1095     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1096       nearly a copy of kpp_transport_s
1097     - there is no analogue to SurfaceTendencyS, so I have to use
1098       gPtr(of the surface layer) instead
1099    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1100    checkpoint50e_pre
1101    
1102    checkpoint50d_post
1103    o change kpp output from multiple-record state files to single-record state
1104      files analogous to write_state.F
1105    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1106      analogous to the cg2d-related output.
1107    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1108      so that writing to internal file fn (with length 512) fails.
1109    checkpoint50d_pre
1110    
1111    checkpoint50c_post
1112    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1113    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1114    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1115    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1116    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1117    
1118    checkpoint50c_pre
1119    Merging from release1_p13:
1120    o bug fix for pkg/seaice dynamic solver
1121    o Added SEAICE_initialHEFF to pkg/seaice
1122    
1123    checkpoint50b_post
1124    o store u*,v* in gU,V instead of in guNm1,gvNm1
1125    o in order to put the momForcing out of the Adams-Bashforth:
1126      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1127      to timestep.F
1128    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1129    o re-generate output for highly sensitive test-exp:
1130       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1131    
1132    checkpoint50b_pre
1133    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1134    o corrected CPP option mismatch in exf_Bulk... functions for case
1135      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1136    
1137    checkpoint50a_post
1138    o Bug fix for merging between c50 and KPP.
1139      ikey was passed from thermodynamics to kpp_calc via
1140      common block rather than being recomputed in kpp_calc,
1141      in contradiction with new key itdkey.
1142      New key ikppkey created, and tamc.h headers updated.
1143    
1144    checkpoint50
1145    - 2nd step of merge with ecco-branch:
1146      merge changes in ecco-branch back into main trunk
1147    - bug fix in find_alpha
1148    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1149    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1150    - merged some sliced AD support routines
1151    
1152    checkpoint49
1153    merged from ecco-branch:
1154    o exf:
1155      - Enable initialisation of forcing fields to constant
1156        (runtime) values.
1157      - in exf_getffields.F
1158        Reduce i-/j-loop to interior domain, discarding overlaps.
1159        That also fixes wrong TAF-key computations for key_1, key_2
1160        with bulf formulae.
1161      - exf_init.F modify #ifdef for exf_init_evap
1162      - exf_getffieldrec.F, ctrl_getrec.F
1163        The following INT-usages are not safe:
1164          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1165          fldcount = int(fldsecs/fldperiod) + 1
1166        and were modified.
1167    o autodiff: checkpoint_lev...
1168      - updated storing for bulk formulae (some arrays were missing)
1169      - added state for seaice package
1170      - synchronized with main branch
1171    o DIVA:
1172      Modif.s in
1173      - the_main_loop.F
1174      - the_model_main.F
1175      and added cost_final_restore.F cost_final_store.F
1176      o With these changes, it is possible to fully separate
1177        the first forward run to compute the cost function (mdthe_main_loop)
1178        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1179        into separate model executions.
1180        This enables better tuning of DIVA to given queue sizes.
1181      o Loss of cost function value in consecutive DIVA runs is
1182        fixed by storing to 'costfinal' file.
1183      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1184        beginning/end of adjoint integration is accounted for.
1185      The current changes apply to TAF-1.4.26.
1186      TAF has one remaining bug, requiring one manual change
1187      (see MITgcm manual).
1188    o cal: synchronized between MAIN and ecco-branch
1189    
1190    checkpoint48i_post
1191    o Changes to restore differentiability of code w.r.t. previous tag
1192      (mostly adding new routines to make list and replacing
1193      pressure by totPhiHyd).
1194    o Updated and merged grdchk package
1195      - has both ADM and TLM checks
1196      - works for single- and multi-proc.
1197      - output cleaned
1198      - worked successfully for parallel DIVA
1199    o genmake:
1200      - Adding -platform=SP4
1201      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1202    o Modif. for DIVA:
1203      ctrl_unpack should not be called in intermediate DIVA interval.
1204      (similar thing would apply for active files such as
1205      tbar, sbar, psbar, which should not be reinitialised;
1206      only relevant for ecco-branch)
1207    
1208    checkpoint48h_post
1209    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1210    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1211    o Added SEAICE_initialHEFF to pkg/seaice
1212    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1213    
1214    checkpoint48g_post
1215    --- EOS:
1216    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1217      store total Potential in totPhyHyd for diagnostics & EOS.
1218    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1219    --- Pressure/geopotential gradient:
1220    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1221    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1222      ( changes results of global_ocean_pressure )
1223    o NLFS + z-coord.: add eta*Rho' contribution.
1224    o accurate phiHyd when using interface-W at the middle between 2 centers
1225     ( changes results of ideal_2D_oce )
1226    o includes r* 2nd term in potential gradient.
1227    
1228    checkpoint48f_post
1229    Merging from release1_p12:
1230    o Modifications for using pkg/exf with pkg/seaice
1231      - improved description of the various forcing configurations
1232      - added basic radiation bulk formulae to pkg/exf
1233      - units/sign fix for evap computation in exf_getffields.F
1234      - updated verification/global_with_exf/results/output.txt
1235    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1236      (SBO) core products, including oceanic mass, center-of-mass,
1237      angular, and bottom pressure (see pkg/sbo/README.sbo).
1238    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1239      to avoid negative values in shallow regions.
1240      - updated verification/natl_box/results/output.txt
1241      - updated verification/lab_sea/results/output.txt
1242    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1243    o Added useSingleCpuIO option (see PARAMS.h).
1244    o Updated useSingleCpuIO option in mdsio_writefield.F to
1245      work with multi-field files, e.g., for single-file pickup.
1246    o pkg/seaice:
1247      - bug fix in growth.F: QNET for no shortwave case
1248      - added HeffFile for specifying initial sea-ice thickness
1249      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1250    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1251      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1252    o pkg/seaice:
1253      - adjoint-friendly modifications
1254      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1255    
1256    checkpoint48e_post
1257    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1258    o dynamics: change definition of computational domain & adapt mom_fluxform
1259      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1260    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1261        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1262        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1263        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1264        inverted_barometer solid-body.cs-32x32x1
1265      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1266    
1267    checkpoint48d_post
1268    o in preparation for r*:
1269     a) use pre-computed gradient of hydrostatic potential:
1270        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1271     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1272        => affects results of glob_oce_pressure (different truncation error)  
1273      update output.txt of ideal_2D_oce & global_ocean_pressure
1274    
1275    checkpoint48d_pre
1276    o in preparation for r*:
1277      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1278      pass the 2 comp. of the grad. as arguments to momentum S/R.
1279      but for the moment, only used if it does not change the results.
1280    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1281    
1282    checkpoint48c_post
1283    Modifications in treatment of initial flux forcing controls
1284    to avoid extra storing of flux fields.
1285    
1286    checkpoint48c_pre
1287    o Added tidal_basin_2d experiment (currently 1D!)
1288    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1289    
1290    checkpoint48b_post
1291    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1292     (modification to pressure gradient not yet implemented)
1293    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1294      (for U & V) that are used for vertical advection of momentum.
1295    
1296    checkpoint48a_post
1297    o In preparation for r*, use temp. array to compute vertical transport
1298       in flux-form momentum pkg. => change results of few test-exp.
1299      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1300                        lab_sea, natl_box & plume_on_slope
1301    
1302    checkpoint48
1303    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1304    
1305    checkpoint47j_post
1306    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1307    o moved adexch from forward_step to addummy_in_stepping
1308    o added exch in ctrl_map_...
1309    o aveFreq.=0. at end of cost_final to avoid overwrite in
1310      reverse checkpointing loop
1311    o Yet more changes in gmredi:
1312      * adgmredi_calc_tensor
1313        avoiding all recomputation of gmredi_slope_limit
1314      * adgmredi_x/y/rtransport
1315        added flag for excessive storing to avoid recomp. of
1316        u/v/rtans, dTdx/y/z
1317        -> this is not really necessary and very memory-consuming
1318      * adgmredi_slope_psi:
1319        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1320      * gmredi_slope_limit
1321        re-activated full calculation of taperfct for case 'ac02'
1322    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1323    
1324    checkpoint47i_post
1325    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1326    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1327      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1328    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1329    o gmredi: fix few bugs.
1330    
1331    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1332    This will be a good checkpoint to plug into the ecco-branch.
1333    o few modif.'s to get latest version adjointed
1334      (mainly kick out code in ini_linear_phisurf)
1335    o modif's to run adjoint with exactConserv
1336    o case GM_BOLUS_ADVEC should be cleaned
1337      S/R gmredi_slope_psi should be cleaned
1338    o verification/carbon now has exactConserv=.TRUE.
1339    
1340    checkpoint47g_post
1341    o time-average AIM output: becomes independent from statvars time-average
1342      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1343    o After TAF bug fix:
1344      Tested adjoint of gmredi package.
1345      Tests were done with checkpoint47 rather than with latest
1346      checkpoint47f_post since the latter is broken for the adjoint
1347      verification/carbon/ contains both ADM and TLM gradient checks.
1348    Here they are, before they get changed/lost/stolen.
1349    Mostly modif.'s to fix numerical sensitivities.
1350    Gradient checks OK for
1351    - GM_taper_scheme:
1352      * clipping
1353      * ac02
1354      * linear
1355      * glw91
1356      * dm95
1357      * ldd97
1358    - GMREDI_OPTIONS:
1359      * GM_VISBECK_VARIABLE_K
1360      * GM_NON_UNITY_DIAGONAL
1361      * GM_EXTRA_DIAGONAL
1362      * GM_BOLUS_ADVEC
1363    in conjunction with data.gmredi parameters to be checked in
1364    in a few minutes under verification/carbon/code/
1365    
1366    checkpoint47f_post
1367    Merging from release1_p10:
1368    o modifications for using pkg/exf with pkg/seaice
1369      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1370        and SEAICE_EXTERNAL_FLUXES
1371      - pkg/exf CPP options EXF_READ_EVAP and
1372        EXF_NO_BULK_COMPUTATIONS
1373      - usage examples are Experiments 8 and 9 in
1374        verification/lab_sea/README
1375      - verification/lab_sea default experiment now uses
1376        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1377    
1378    checkpoint47e_post
1379    o created a tag prior to creating a branch
1380    
1381    checkpoint47d_post
1382    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1383      at the bottom boundary had an erroneous half slip boundary condition
1384    o added bottom drag and no slip boundary condition capabilities to
1385      oceanic pressure coordinates code
1386    o added new verification experiment global_ocean_pressure, this experiment is
1387      also described in the tutorial section of the manual
1388    checkpoint47d_pre
1389    
1390    checkpoint47c_post
1391    o Added a verification experiment for a global cubed-sphere ocean run
1392      -  verification/global_ocean.cubed32x32x30
1393      -  uses pkg/therm_seaice and pkg/bulk_forcing
1394    
1395    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1396    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1397      when using P-coordinate; only implemented for atmospheric config.
1398    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1399      NOTES: requires option NONLIN_FRSURF to be "#define".
1400    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1401    
1402    checkpoint47b_post
1403    Merging from release1_p9:
1404    o pkg/seaice
1405      - removed GOTO's and added taf directives
1406      - double precision constants to reduce the g77 (Linux)
1407        to F77 (SGI) differences reported in release1_p8
1408    o tools/genmake
1409      - added SGI options
1410    o verification/testscript
1411      - updated to that of checkpoint47a_post
1412    o verification/global_ocean.90x40x15/input/eedata
1413      - modified for SGI f77 compatibility
1414    o verification/lab_sea
1415      - added description of sea-ice model
1416      - added missing matlab routines
1417      - added test of thermodynamics parallelization
1418    
1419    checkpoint47a_post
1420    o new pkg: aim_v23
1421     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1422       for now, keep the same surface forcing as before.
1423     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1424     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1425     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1426    o add diagnostic of surface correction term in monitor output
1427    
1428    o bulk_force and therm_seaice
1429    - Two packages:  bulk_force (Bulk forcing)
1430      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1431    - Earlier integration from Stephaine Dutkiewicz
1432      and Patrick Heimbach.
1433    - Two ifdef statements for compile time,
1434       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1435    
1436    checkpoint47
1437    differentiable version of checkpoint46n_post
1438    o bug fix in quasihydrostaticterms
1439    o * "clean" adjoint code (in terms of extensive recomputations)
1440        can now be obtained for all GMREDI options (i.e. for
1441        - GM_VISBECK_VARIABLE_K
1442        - GM_NON_UNITY_DIAGONAL
1443        - GM_EXTRA_DIAGONAL
1444        - GM_BOLUS_ADVEC )
1445      * However, wrong gradient check problem remains unsolved.
1446      * New CPP options have been introduced for different
1447        tapering schemes
1448    o external_fields_load now part of differentiation list
1449    o pressure needs multiple storing;
1450      would be nice to have store_pressure at beginning or
1451      end of forward_step, e.g. by having phiHyd global (5-dim.)
1452      (NB: pressure is needed for certain cases in find_rho,
1453      which is also invoked through convective_adjustment).
1454    o recomputations in find_rho for cases
1455     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1456    o #define ATMOSPHERIC_LOADING should be differentiable
1457    o ini_forcing shifted to begining of initialise_varia
1458    o Incorporating QNVS line search routines into MITgcm
1459      (this is separate code, and therefore not under pkg)
1460      lsopt/, optim/
1461    o Updated verification/carbon/
1462      - #define GM_VISBECK_VARIABLE_K
1463      - GM_taper_scheme    = 'ldd97'    
1464    
1465    checkpoint46n_post
1466    Merging from release1_p8:
1467    o verification/natl_box:
1468      updating new external_fields_load routine
1469    o New package: pkg/seaice
1470      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1471      The sea-ice code is based on Hibler (1979-1980).
1472      Two sea-ice dynamic solvers, ADI and LSR, are included.
1473      In addition to computing prognostic sea-ice variables and diagnosing
1474      the forcing/external data fields that drive the ocean model,
1475      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1476      The implied surface heat flux is then stored in variable
1477      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1478      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1479      non-local transport term.  Because this call precedes model
1480      thermodynamics, temperature under sea-ice may not be "exactly" at
1481      the freezing point by the time theta is dumped or time-averaged.
1482      N.B.: fairly large differences in accuracy occur across
1483            different platforms/compilers; comparison between
1484            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1485            generated output gives:
1486       T           S           U           V
1487      C D M    c        m  s        m  s        m  s        m  s
1488      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
1489      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d

1491    
1492      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1493    o GAD:
1494      - generated new common blocks to account for call of
1495        same gad routines with differing traceridentities
1496        (needed to modify tracerIdentity indices in GAD.h)
1497      - generated separate common blocks for case useCubedSphereExchange
1498        (Department of Futurology)
1499      - parameter lists to gmredi_?transport: added tracerIdentity
1500      - added new key indices to tamc.h
1501    o external_fields_load:
1502      - added this routine to TAF list
1503      - needed to make some common blocks global and additional storing
1504        along the same lines as exf package (checkpoint_lev?_directives.h)
1505    o exf:
1506      updated external forcing package
1507      - bug fixes carried over from ecco-branch
1508        (missing OBCS_OPTIONS.h in two routines)
1509      - enable easy to use "no forcing".
1510      - added exf I/O for atmospheric loading
1511      - added exf I/O for runoff data
1512      - transfered scaling between exf <-> MITgcm to exf namelist
1513    o Adding new verification experiment global_with_exf.
1514      This verification experiment is almost identical to the
1515      global_ocean.90x40x15 experiment, except that it uses
1516      the exf (and cal) package instead of the
1517      external_fields_load routine (cf README file).
1518    
1519    checkpoint46m_post
1520    o modified testscript to return -- when there are no lines of "%MON" output
1521    o added new flag "quasiHydrostatic" for QH mode
1522      and new routine quasihydrostaticterms()
1523    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1524      New routine: mom_u_coriolis_nh()
1525    o fixed sign of non-hydrostatic metric terms in u and v equations.
1526      Depend on correct sign of gravitySign.
1527    o added work.pc* to .cvsignore in aim directories using ifc
1528    o introduced flag for controllin non-hydrostatic metric terms
1529    o removed gravitySign from PARM04
1530    o switched to g77/ifc from pgf77 in aim experiments
1531    
1532    checkpoint46l_post
1533    o made convective adjustment work with pressure coordinates:
1534     - changed the direction of k-loop in convective_adjustment.F for the
1535       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1536     - adjusted the reference pressure k-index in convective_adjustment.F
1537     - adjusted the convection condition in convect.F (in analogy to
1538       calc_ivdc.F)
1539     - convective_adjustment no longer computes anything on the halos
1540     - removed the warnings about negative salinity from find_rho.F and
1541       find_alpha.F; instead the new routine look_for_neg_salinity, called
1542       at the beginning of find_rho, find_alpha, and find_beta, does a
1543       check of the entire slice, if CPP-option
1544       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1545    checkpoint46l_pre
1546    
1547    checkpoint46k_post
1548    o fixed the verification/global_ocean.90x40x15 experiment:
1549     - new bathymetry (the world according to A., JMC, and M.)
1550     - new initial fields and forcing fields (*.bin files)
1551     - new POLY3.COEFFS (for the next release one should switch to a full
1552       equation of state: JMD95P or MDJWF)
1553     - fixed several errors and redundancies in the data file
1554     - experiment uses looped cells
1555     - added matlab directory with diagnostic scripts for plotting of output
1556    
1557    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1558     - read AIM physics parameters from a file (data.aimphys)
1559     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1560    
1561    checkpoint46j_post
1562    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1563    o move wVel computation at the end of the time step, in S/R integr_continuity
1564    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1565    o update timeave pkg for wVel diagnostic.
1566    checkpoint46j_pre
1567    
1568    checkpoint46i_post
1569    o Clean up AIM package (and keep the results unchanged):
1570      include CPP_OPTION and use IMPLICT NONE in all routines ;
1571      declare all the variables _RL ; use _d 0 for all numerical constants.
1572      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1573    
1574    checkpoint46h_post
1575    o cleaned up the use of rhoNil and rhoConst.
1576      - rhoNil should only appear in the LINEAR equation of state, everywhere
1577        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1578        and the dynamical equations are all divided by rhoConst
1579    o introduced new parameter rhoConstFresh, a reference density of fresh
1580      water, to remove the fresh water flux's dependence on rhoNil. The default
1581      value is 999.8 kg/m^3
1582    o cleanup up external_forcing.F and external_forcing_surf.F
1583      - can now be used by both OCEANIC and OCEANICP
1584    checkpoint46h_pre
1585    
1586     Added code to convert surface volume flux (fresh water) into
1587     a mass flux when using P coordinates in the ocean (OCEANICP).
1588     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1589    
1590    checkpoint46g_post
1591    o Include a new diagnostic variable phiHydLow for the ocean model
1592      - in z-coordinates, it is the bottom pressure anomaly
1593      - in p-coordinates, it is the sea surface elevation
1594      - in both cases, these variable have global drift, reflecting the mass
1595        drift in z-coordinates and the volume drift in p-coordinates
1596      - included time averaging for phiHydLow, be aware of the drift!
1597    o depth-dependent computation of Bo_surf for pressure coordinates
1598      in the ocean (buoyancyRelation='OCEANICP')
1599      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1600        Theta, Salinity, and Pressure in the parameter list. This routine is
1601        presently contained in find_rho.F. This routine does not give the
1602        correct density for 'POLY3', which would be a z-dependent reference
1603        density.
1604    o cleaned up find_rho
1605      - removed obsolete 'eqn' from the parameter list.
1606    o added two new verification experiments: gop and goz
1607      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1608    checkpoint46g_pre
1609    
1610    checkpoint46f_post
1611    o Enable tangent linear (forward mode) gradient checks:
1612      - extended active file handling to g_... files
1613      - added TANGENT_SIMULATION to theSimulationMode
1614      - extended grdchk package accordingly
1615    o added tangent linear setup in verification/carbon/code_ftl
1616    o added adjoint setup in verification/front_relax/code_ad
1617    
1618    checkpoint46e_post
1619    o Added new equation of state -> MDJWF
1620      - EOS of McDougall et al., 2002, JAOT, submitted
1621      - caveat: the equation of state is only valid for a smaller (more
1622        realistic?) range of values than JMD95P/Z and UNESCO
1623      - added masks to the calculation of pressure in store_pressure
1624      - added more check values for density in check_eos (ini_eos.F), some of
1625        the old check values are out of the range of the MDJWF-eos, so don't
1626        expect perfect matches for those
1627    checkpoint46e_pre
1628    
1629    checkpoint46d_post
1630    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1631      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1632      case of pressure coordinates. eosType='JMD95Z' in
1633      combination with buoyancyRelation='OCEANICP' now causes an error.
1634    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1635      in find_alpha/beta.
1636    checkpoint46d_pre
1637    
1638    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1639      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1640    
1641    checkpoint46c_post
1642    o Changes necessary for ocean in p-coordinates
1643     -  Added new buoyancy relation = 'OCEANICP'
1644     -  Added new parameters = gravitySign (this used to be contained inside
1645        the factor dRdZ which I added when we first switched to R coordinates).
1646     X GM/Redi is not compatible (yet)
1647     X bottom drag and no-slip need to be debugged.
1648    checkpoint46c_pre
1649    
1650    checkpoint46b_post
1651    o Added new equation of state -> JMD95Z and JMD95P
1652      - EOS of Jackett and McDougall, 1995, JAOT
1653      - moved all EOS parameters into EOS.h
1654      - new routines ini_eos.F, store_pressure.F
1655    o Added UNESCO EOS, but not recommended because it requires
1656      in-situ temperature (see JMD95)
1657    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1658      unesco.f to be used with POLY3
1659    checkpoint46b_pre
1660    
1661    checkpoint46a_post
1662    o Added (atmospheric) pressure loading
1663      - new field in FFIELDS.h, etc...
1664      - new cpp flag ATMOSPHERIC_LOADING
1665    o Changed hFacC to _hFacC in calc_phi_hyd.F
1666    o Added SHORTWAVE_HEATING to some files for consistency
1667    checkpoint46a_pre
1668    
1669    checkpoint46

1676      - Compatible with new ctrl package
1677      - added Eliassen Palm cost hooks
1678      - modif's of existing cost functions
1679    o Adjoint-related bug fixes in kpp:

1695    
1696    checkpoint45d_post
1697    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1698    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1699      (affects plume_on_slope "cg2d" output)
1700    o add new parameter deltaTfreesurf for free-surface time stepping
1701    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1702    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B

1721    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1722      to configure barotropic setup (Martin Losch)
1723    o moved some initialisations within bi,bj loop in dynamics
1724      (TAF flow dependency)
1725    o in initialise_varia, moved call packages_init_variables
1726      before convective_adjustment_init
1727      (corresponding adjustment of TAF tape initialisation).
1728    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1729    
1730    checkpoint45a_post
1731    o compute Rho over the whole domain (extend iMin,jMin indices)
1732    o specific exchange for X-slice domain (case Ny=1)
1733    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1734    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1735    
1736    checkpoint44h_post = checkpoint45
1737    o Fix to restore differentiability:
1738      place at which packages_init_variables is called in

1755    
1756    checkpoint44g_post
1757    o fix surface correction term in multiDimAdvection (affects plume_on_slope

1768      + Not implemented so far:
1769        - KPP
1770        - OBCS
1771      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1772        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1773        line in data.pkg.
1774      + This package is disabled by default since it increases storage.
1775    
1776    
1777    o testscript: added -cleanup option

1784      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1785      Original calls to convect() still in place.
1786    
1787    chkpt44d_pre,post
1788    o added missing EXCLUDE_MONITOR flags
1789    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
1790      (incompatible typ in MIN/MAX expressions caused problems
1791      on IBM SP3)
1792    o in genmake added variable MAKEDEPEND
1793      plus resetting for case SunOS
1794    o added timer_stats.c routine for IBM SP3

1874                        bi,bj loop
1875      mdsio_writelocal - same as mdsio_writetile except works for local
1876                         arrays
1877      write_local_r? - higher-level wrapper for mdsio_writelocal
1878      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1879      Example given at end of mom_vecinv.F that dumps some local arrays.

1883      or genmake -DISABLE ...
1884    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1885      (additional storing is now needed for case vecinv;
1886      currently nothing implemented to switch this storing off
1887      in case fluxform is used since no CPP flag available).
1888    
1889    checkpoint40pre7
