3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    o parameter calendarDumps: when set, approximate months (30-31 days) and years
6      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
7      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
8      months and years.  Requires pkg/cal.
9    o diagnostics: add pickup functionality
10      - off by default for backwards compatibility
11      - current version only uses MDSIO -- MNC will be added
12    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
13    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
14    
15    checkpoint57d_post
16    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
17    o modify verification/ideal_2D_oce so that it tests the creation of mnc
18      output from the diagnostics package
19    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
20    o make genmake2 more portable by using ".$FS" instead of ".f" for more
21      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
22    o add coordinate variables to the MNC output from the diagnostics package
23    o change MNC-flags default value: true when useMNC=TRUE
24    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
25      the ability (off by default) to read the grid information using MNC
26    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
27    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
28    o do snap-shot diagnostics at the middle of the time-interval (instead of
29      at the end).
30    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
31      new test for AIM with thSIce + slab-ocean
32    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
33    o move state variable diagnostics to the beginning of the time step ;
34      (note: still needs some work specially for snap-shot diagnostics)
35      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
36    
37    checkpoint57c_post
38    o Change testing option (-ieee) to get closer agreement between g77 & ifort
39    o generate new output.txt files on faulks with g77 & the new -ieee option
40    checkpoint57c_pre
41    
42    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
43      update output.txt of exp. global_ocean.90x40x15
44    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
45      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
46    o add saltFlux(+File) forcing capability with periodicExternalForcing
47    o allow to use pkg diagnostics for GM-Redi & ThSIce output
48    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
49    o improvements for the MNC output from DIAGNOSTICS:
50      - correct handling of the unlimitied dimension
51      - all dims now have associated coordinate variables
52      - variables located at U, V, and Corner ("Z") points are now written
53        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
54        *all* data points are output
55    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
56    o added pkg/seaice/seaice_monitor.F
57    o mdsio_readfield.F can now read files visible only to master MPI process.
58    o pkg/seaice: some test code for ice-modified ocean stress
59    o exf_getffields interpolation defaults to bilinear for all scalar forcing
60      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
61      spurious negative numbers for precipitation and humidity.  Will cause
62      some small numerical differences for integrations using pkg/exf/exf_interp.F.
63    o pkg/ctrl/
64      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
65        May be enabled via doPackDiag
66      *  introduce z-scaling of
67         + gradient (doZscalePack) and
68         + control (doZscaleUnpack)
69    o pkg/mdsio/
70      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
71      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
72    
73    checkpoint57b_post
74    o simplify options in diagnostics_fill arguments (remove weird combinations)
75    o fix MNC coordinate variables so that they now contain per-face index
76      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
77      general, EXCH2 grids are only aligned to a "local" coordinate system
78    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
79    o Implement instantaneous output within pkg diagnostics:
80      setting a negative frequency in data.diagnostics produces
81     "snap-shot" output (as opposed to time-average if freq > 0)
82    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
83      NOTE: change ptracer diagnostics name: use 2 characters to work with
84            more than 9 tracers. Add also diagnostics of advect & diffus flux.
85    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
86      becomes the coordinate variable for the 'T' dimension
87    o add CF-style coordinate variables to MNC
88      - just a first cut:  numbers are meaningless on the cubesphere and
89        missing along the T axis but otherwise it works!
90    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
91    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
92    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
93      this is based directly on what the model compute, so that the content of
94      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
95    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
96    o clean up build options files for SunOS, in particular
97      - remove -traditional from xmakedepend
98      - change -xarch=v9 to -xarch=native for f77
99      - restore use of make (not gmake)
100      - add CC=gcc if using g77
101    o changes per discussion of AM, JMC, & EH3 today:
102      - move redundant "grid" variables out of "state" -- in preparation of
103        creating proper CF-style coordinate variables and in recognition
104        that any/all grid variables can be easily copied (eg. w/NCO) from
105        the grid files into any of the other NetCDF files
106      - *always* output grid variables with MDSIO (this will eventually be
107        changed)
108      - output MNC grid file if useMNC is true
109    o every instance of _END_MASTER() has been found and replaced with
110      _END_MASTER( myThid ) in order to satisfy certain picky Sun
111      preprocessors
112    o re-arrange diagnostics pkg initialisation:
113     - allow each package to extend the available diagnostics list
114     - add some checking and fix small problems (multi-threaded, ...)
115     - new S/R diagnostics_fill (replace fill_diagnostics):
116       look through the short list of active diag. (instead of the long list)
117       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
118    
119    checkpoint57a_post
120    o this set of changes restores TAMC compatibility
121      tested for global_ocean.90x40x15 adjoint on trough
122      (what a pain)
123    
124    checkpoint57a_pre
125    o some modifs in tools/build_options for sunos
126    o call ctrl_pack for ctrl at end for optimcycle=0
127    
128    checkpoint57
129    o add horizontal bi-harmonic viscosity for vertical velocity
130      - new parameter viscA4W (defaults to viscA4)
131      - affects only non-hydrostatic code
132      - to be done: no-slip lateral boundary conditions
133    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
134    o implement Implicit Vertical advection for pTracers
135    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
136      (implemented also for implicit vertical diffusion & advection)
137    o OBCS: extend application of tracer open boundary conditions
138      to a strip beyond the boundary of width Olx/Oly
139    o add call monitor to TAF set of required calls (flow directives)
140      and include in natl_box_adjoint
141    o untangle a few ifdefs related to cost, ctrl, autodiff
142      untangel a few ALLOW_ECCO_OPTIMIZATION
143    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
144      (theta2, salt2 in ecco_cost_weights)
145    
146    checkpoint56c_post
147    o OBCS as control variables
148      - update ctrl_ad_diff.list, obcs_ad_diff.list
149      - remove balance of obcs controls from default
150      - fix index bug nobcs in ctrl_init
151      - fix dummy fields filen in ctrl_pack
152      - add dummy weights for obcs
153    o lsopt: comment out fort.94 output
154    o optim:
155      - remove unnecessary header files
156      - adjusted namelists
157      - add xerbla.F to Makefile
158    o exf:
159      - multiple modifications of exf_check_range
160      - unit change in exf_init_runoff from [m/year] to [m/s]
161    o mdsio:
162      - i/o-vector change debugLevel from debLevA to debLevB
163    
164    checkpoint56b_post
165    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
166      is called from DO_THE_MODEL_IO
167      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
168      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
169      - clean up PTRACERS_WRITE_TIMEAVE a little
170    o add another verification experiment that tests both the cfc-pkg and
171      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
172      reactive tendencies treated inline with regular timestepping
173    o testreport previously did a lousy job of comparing small numbers, so
174      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
175      implemented in the little c-progam tmp_cmpnum.c which is embedded in
176      testreport.
177    o ptracers_monitor: bug fix for MPI
178    
179    checkpoint56a_post
180    o GCHEM: finish reorganizating the package
181      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
182        (introduces another 3D-array for each passive tracer, but only if
183        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
184        gchemTendency is not needed because the timestep is done separately)
185      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
186      - GCHEM is now---more or less cleanly---separate from PTRACERS
187      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
188        so clear to me how that should be done in a general way.
189    o CFC: improve formatting of output in CFC_ATMOS
190    o PTRACERS:
191      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
192        that ALL experiments with ptracers enable can be checked. This makes
193        GCHEM_MONITOR obsolete.
194      - include a runtime parameter PTRACERS_monitorFreq that defaults to
195        monitorFreq
196      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
197    o add PTRACERS (PTR0[1-5]) to testreport output
198    o exf_check_range:
199      * default changed to .TRUE.
200      * will check values for niter0 if debLevA, every timestep if debLevB
201      * STOP in exf_check_range if 'out of range'
202      * range chosen generous to allow for potential extema
203      TBD: a version with stricter range
204           permitted range would be runtime parameters
205    o GMredi:
206      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
207      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
208      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
209    o GCHEM:
210      - move call to GCHEM_FORCING_SEP, so that it is now called before
211        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
212      - introduced a useGCHEM runtime flag and applied it everywhere.
213      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
214        this flag is now only visible within GCHEM-pkg routines.
215      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
216        be replaced by a 3D array that is computed before thermodynamics; for
217        this, the tracer ID iTracer had to be included into the parameter list
218        of ptracers_forcing
219      - set up forward_step to call gchem_forcing, that will replace
220        gchem_forcing_int in ptracers_forcing
221      - cleaning up
222    o small cleaning of exch2: remove files that are also in eesupp/src
223    
224    checkpoint56
225    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
226    o mnc: cleanup "full" files--fixes out-of-memory problem
227    o ECCO-GODAE
228      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
229      * fully merged and updated from SIO code
230        windstress sign change affects
231        - exf_inscal_[u/v]stress
232        - sign of xx_tau[u/v] adjustments
233        - signs in cost_scat
234      * ctrl_get_gen: avoid update of tau[u/v] for first few days
235      * natl_box_adjoint updated and compressed
236      * 2-level checkpoint switch added
237        (tested in EXP. 1 of natl_box_adjoint)
238      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
239    o SVD
240      * first complete, non-hacked version for SVD calculations
241      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
242        performed via direct access files admtlm_vector.it????
243        (via ctrl_[un]pack)
244      * optimcycle is used for ARPACK iteration counter
245        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
246      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
247        and add linear transforms where necessary
248      * controls are initial/final SST, SSS (can be extended; need to check
249        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
250    o mdsio: filename info to both stderr, stdout
251    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
252      from sign change
253    
254    checkpoint55j_post
255    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
256      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
257    o add consistent build directories and .cvsignore files to verification
258    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
259    o make all subroutines 30 or less characters in length for certain older
260      compilers to work (a thorough search only turns up two routines in
261      pkg/ptracers)
262    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
263      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
264    
265    checkpoint55i_post
266    o change arrays for total vertical diffusivity (2.D if explicit,
267      3.D if implicit) ; each ptracer uses its own background value.
268    o added mnc/NetCDF output capability to ocn_compon_interf
269      - added bits to verification/cpl_aim+ocn so that it can run on
270        ITRDA and other clusters without the mpirun "-wd" option
271    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
272      configuration
273    o give MNC the ability to create additional files rather than
274      exceeding a specified file size limit "MNC_MAX_FILESIZE"
275      - the default is just less than 2GB which is a practical limit
276        on many systems
277    o Compute the non-local term using either KPP vertical diffusivity (=default)
278       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
279    
280    checkpoint55h_post
281    o add verification test "vermix"
282    o remove all the *_ioinc flags and replace with the single global
283      outputTypesInclusive flag
284    o allow to set a vertical profile of vertical diffusivity for T & S
285    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
286    o useMNC moved from data.mnc to data.pkg
287    
288    checkpoint55g_post
289    o Renaming carbon AD experiments to comply with testreport conventions
290    o Updating adjoint of Held-Suarez hs94.1x64x5
291    o Fixing directives for non-ECCO forward_step, after ECCO directives
292      have been fixed to avoid recomp. of do_oceanic_phys
293      Works well for global_ocean.90x40x15,
294      but recomp. issue remains for carbon
295    o Updating adjoint output for natl_box_adjoint after
296      pkg/ecco has been modified (see taga c55d_post)
297    
298    checkpoint55f_post
299    o rename to timeave_init_fixed
300    
301    checkpoint55e_post
302    o some delicate re-shuffle of store directives to avoid one
303      extra call of do_oceanic_physics
304      affects ecco_the_main_loop.F, do_oceanic_physics.F
305      checkpoint_lev1_directives.h
306    o NB: this may break global_ocean adjoint temporarily,
307      but it is clear how to fix it. Will do later, need this now.
308    
309    checkpoint55d_post
310    o ECCO specific cost function terms (up-to-date with 1x1 runs)
311    o ecco_cost_weights is modified to 1x1 runs
312    o modifs to allow observations to be read in as
313      single file or yearly files
314    o enable to read exf forcing fields as either
315      single file or yearly files (flag useExfYearlyFields)
316    checkpoint55d_pre
317    
318    o switch between 2-level and 3-level checkpointing
319    o add ability of MNC to write local and "partial" (eg. 2D slices where
320      the full 3D field is never actually stored) arrays to NetCDF files
321      with the correct (that is, the complete multi-dimensional) set of
322      array indicies
323      - used in mom_vecinv() to write the diagFreq output
324      - tested (demonstrated) in verification/aim.5l_cs
325    o further mnc-ification
326      - add verification/lab_sea to the list with mnc setups
327      - fix undefined mnc v-names in cd_code
328      - add kpp to mnc output (both snapshot and timeave)
329    o non-hydrostatic code
330      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
331        in calc_gw.F
332      - defaults to viscAh
333      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
334        friction or Leith) in non-hydrostatic mode, as long as there is
335        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
336    o pkg/cost
337      extend simple cost functions to treat time mean quantities
338      (T,U,V) via cost_accumulate_state from cost_tile
339    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
340        be 2 times larger than the minimum size the advection scheme requires.
341        now get a perfect conservation of salt in advect_cs test-exp (updated)
342    o GGL90 (Gaspar's TKE mixed layer)
343      - add horizontal diffusion of TKE, requires exchanges in
344        do_fields_blocking_exchanges, horizontal diffusivity is zero by
345        default. In OPA there is no horizontal diffusion of TKE but the
346        mixing coefficients are computed from a horizontal average of TKE of
347        6 points or so. I think that diffusion has a little more physical
348        justification.
349      - clean up ggl90_calc in the hope of reducing memory usage (this hope
350        was in vain)
351      - mask tke-variable in ggl90_init
352    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
353    o fix biharmonic diffusion on CS-grid.
354    o more obcs stuff
355      - added obcs_external_fields_load as an alternative to the EXF-pkg option
356        for reading boundary values. This routine is called from
357        obcs_prescribe_read
358      - updated obcs_check
359      - changed sponge layer relaxation parameter units for days to seconds
360      - turned off sponge layer by default
361      - changed argument list of OBCS_CALC to myTime+deltaTclock
362      - fixed about 35 bugs in obcs_external_fields_load
363    
364    checkpoint55c_post
365    o obcs stuff
366      - new runtime flags useOBCSprescribe, useOBCSbalance
367      - re-arranged obcs_calc
368      - moved exf_getobcs to obcs_prescibe_read
369        obcs_prescibe_read is called after ORLANSKI stuff
370        and independent of it (executable can contain all).
371      - updated obcs_check
372      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
373        These may be necessary only if tangential velocities are
374        prescribed at OB, not sure, needs testing.
375    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
376      which simplifies the calls and passes the ifc check-bounds test
377    
378    checkpoint55b_post
379    o add a 2D scalar, Z location, exchange_2 routine.
380    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
381      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
382      affects advect_cs results (for the wrong reason): update output.txt
383    o use a more standard discretization for biharmonic viscosity ;
384     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
385      affects results of dome set-up: update output.txt
386    o fix gad_advection.F (CubedSphere part), back to version 1.23
387    o fix bug in mom_vi_del2uv.F (CubedSphere part).
388    
389    checkpoint55a_post
390    o merged code to
391      * prescribe/read time-dependent open boundaries
392        (works in conjunction with exf, cal)
393      * sponge layer code for open boundaries
394      * each boundary N/S/E/W now has its own CPP option
395        (healthy for the adjoint)
396    
397    checkpoint55
398    o up-to-date adjoint of previous breaks
399      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
400      - global_ocean_ebm: adjoint still needs fix (TLM ok)
401      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
402      - carbon: * remove tr1-related adjoint verification
403                * add ptracer as control variable
404    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
405      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
406    
407    checkpoint54f_post
408    o in verification/carbin/ remove experiment related to
409      ALLOW_PASSIVE_TRACER (array tr1 etc)
410      code_ad/ input_ad/ results_ad
411    
412    o add two new packages
413      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
414        + subject to optimization (memory)
415      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
416        + subject to reordering (many GOTOs in the original code)
417        + so far opps is called for every (i,j) point, and then operates in
418          the vertical; one may want to reorder the scheme in order operate in
419          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
420          fields)
421    o overhaul of IO so that we now have flags for MDSIO and/or MNC
422      - all verification tests compile and run with linux_ia32_g77
423      - defaults are compatible with current input files--nothing
424        should change if you were not previously using MNC
425      - MNC output has been added in numerous places (eg. timeave)
426        but there are still a few writes not yet do-able with MNC
427        (this is in progress)
428      - flags now allow for either/or/both use of MDSIO and MNC and
429        documentation will soon follow
430      - numerous small formatting cleanups for ProTeX
431    o add version info (via BUILD_INFO.h) to MNC and stdout
432    
433    checkpoint54e_post
434    o add two new packages
435      - pp81 (Packanowski and Philander, 1981), Richardson number and
436        stratification dependent mixing
437      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
438      - these scheme operate in a similar manner as KPP (without ghat, of
439        course), however there is only one diffusivity that is used for both
440        temperature and salinity (and passive tracers)ç
441    o add offline package
442    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
443      provided by Stephanie Dutkiewicz
444    o genmake2: add ability to search for C compilers and cleanup test output
445      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
446    
447    checkpoint54d_post
448    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
449    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
450      leading to additional shift by 5 days each year of integration
451       (i.e. leading to considerable offset over the years)
452    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
453    o start with no AB and no initial filtering (staggerTimeStep):
454      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
455    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
456      (external loading & cpl import/export stay in forward_step.F)
457    o update coupling interface to work with new staggerTimeStep
458    o change MDSIO ptracers_pickup.
459    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
460    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
461    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
462    
463    checkpoint54c_post
464    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
465      this affects (truncation error) output.txt of test-exp:
466       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
467    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
468    o change Qnet to always be the net heat flux, (+upward).
469      affects (truncation error) output of natl_box exp.: updated
470    o define the max number of passive tracers in PTRACERS_SIZE.h
471    o start to test mnc routinely in exp0
472    o add sea-ice loading (sIceLoad) as a new forcing field.
473    
474    checkpoint54b_post
475    o add testreport "-j JOBS" option for parallel builds (tested and pretty
476       impressive on Altix and Opteron systems)
477    o diagnostics can now write NetCDF files through the mnc package
478    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
479    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
480    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
481      affects (truncation error) output of lab_sea & natl_box exp.: updated
482    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
483    
484    checkpoint54a_post
485    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
486    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
487    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
488    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
489      + internal_wave (shift in writing cg2d_ini_res)
490    checkpoint54a_pre
491    
492    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
493      - modified verification/lab_sea and natl_box_adjoint accordingly
494    
495    checkpoint54
496    checkpoint53g_post
497    o prepare splitting of thermodynamics: store convect.counter in common block
498    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
499      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
500    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
501    o new parameter "nShapS": allow to treat differently S from T (nShapT)
502    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
503    o restore adjointability
504    
505    checkpoint53f_post
506    o modifications that affect AIM experiment results (update output.txt):
507      - no advection of S at top interface Nr (pkg/generic_advdiff)
508      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
509    o AIM pkg:
510      - include stability function into surf.Flux derivative relative to Tsurf
511      - calculate clear-sky radiation & surface temp. change (for diagnostics)
512    
513    checkpoint53e_post
514    o merged cylindrical coord configuration
515    o added rotating_tank experiment
516    checkpoint53e_pre
517    
518    checkpoint53d_post
519    o faulks upgraded: re-generate output.txt that have changed:
520       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
521    o Added Bryan and Lewis, 1979, vertical diffusivity profile
522    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
523    o added Sadourny discretization of Coriolis
524      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
525      - re-enabled use of omega3 (useAbsVorticity)
526    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
527      vector-invariant equations
528      - note: does *NOT* yet use same variable visc. for no-slip BC's.
529    o recoded the lateral boundary conditions for non-hydrostatic w, this time
530      hopefully without new bugs
531      - still to do: biharmonic friction for non-hydrostatic w
532    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
533    o regenerated output for global_ocean_ebm (using -ieee)
534    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
535      of mom_common/
536      - simple re-arrangement of instructions within computing loop
537    checkpoint53d_pre
538    
539    checkpoint53c_post
540    o new version of coupler for AIM+thSIce and Ocean models
541     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
542     - land: change Evaporation of snow
543     - aim with thSIce: fix bug in snow-precip.
544    o changes to calc_gw.F
545     - bug fix for w^2 term near the bottom boundary
546     - (hopefully) improve the lateral slip boundary condtions for use with
547        partial/looped cells
548      - because the bug fix changes two verification experiments anyway (exp5
549        and plume on slope), change the lateral boundary condition from half slip
550        to the value of no_slip_sides
551    o ebm package wasnt quite up to the parallel task. Fixed that.
552    o Adjoint of EBM package + verification
553      * TLM OK
554      * ADM not sufficient accuracy yet (needs further testing)
555    
556    checkpoint53b_post
557    o Commiting new energy balance model to repository
558      * package is pkg/ebm
559      * verif. is verification/global_ocean_ebm
560      * references are in ebm_driver.F
561    C      * X. Wang, P. Stone and J. Marotzke, 1999:
562    C        Global thermohaline circulation. Part I:
563    C        Sensitivity to atmospheric moisture transport.
564    C        J. Climate 12(1), 71-82
565    C      * X. Wang, P. Stone and J. Marotzke, 1999:
566    C        Global thermohaline circulation. Part II:
567    C        Sensitivity with interactive transport.
568    C        J. Climate 12(1), 83-91
569    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
570    C        Destabilization of the thermohaline circulation
571    C        by atmospheric eddy transports.
572    C        J. Climate 7(12), 1870-1882
573    o Will need long integration testing.
574    checkpoint53b_pre
575    
576    o created pkg/mom_common in preparation for variable viscosity code
577    o renamed and split ini_mnc_io
578    o pkg/land: only liquid water can diffuse or run-off
579    o AIM using land: soil wetness availability account for snow
580    o added printMapIncludesZeros to EEPARMS namelist
581    
582    checkpoint53a_post
583    o restore TAMC compatiility for exf_constants.h
584      (no usage of _d in .h)
585    o Additional storing in KPP in an attempt to fix
586      TAMC problem with adjoint of KPP code.
587      (no success...)
588      Identical code works fine with TAF.
589    o Fixed verification/natl_box_adjoint experiments.
590      Initial conditions for Experiments 4 and 5 are now
591      set to "SEAICE_initialHEFF=0", which is more reasonable,
592      and hence gives results closer to that of Experiment 2.
593      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
594    
595    checkpoint53
596    o stable checkpoint with up to date adjoint
597      TLM tests only run for 1st grdchk at the moment. Its unclear if
598      this is a code problem or a problem with resetting code for g_
599      variables that is being autogenerated wrong.
600      Otherwise:
601       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
602       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
603         are both still in chaos following their security messes.
604    
605    checkpoint52n_post
606    o various build (mostly genmake2) changes including:
607      - ability to build/run more easily within Cygwin and MacOS X
608      - more complicated Makefiles with a stronger dependence on Gnu Make
609    o pkg/seaice modifications
610      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
611        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
612        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
613      - changed proxy for geostrophic velocity and updated
614        verification/lab_sea/results/* accordingly
615      - removed ADI dynamic solver from pkg/seaice
616      - replaced all occurrences of 1/CSTICE or 1/CSUICE
617        they caused a segmentation fault under certain circumstances
618      - removed unused field WATR
619    o bug fix in exf-package:
620      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
621         now reflect that.
622    o small fixes in the cal-package:
623      - set reference date to first of January for the 'model'-calendar
624      - failing of cal_CheckDate in cal_FullDate now actually results in a
625        warning
626    o small modifications in exf-package to increase flexibility:
627      - change climtempfreeze from a constant to a runtime parameter that
628        is specified in data.exf_clim (default = -1.9)
629      - introduce runtime parameter windstressmax (default = 2.0) that is
630        specified in data.exf
631    o fix in pkg/thsice:
632      - update Evap (Tsf changes) to be consistent with Latent heat flux
633      - maintain snow precipitation unchanged (even if Tsf >=0).
634     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
635    
636    checkpoint52m_post
637    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
638      this does not change any of the results, because myIter=0 in swfrac always
639      lead to jwtype=2 (the default anyway), but the call makes little sense
640      as a default
641    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
642    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
643      atmospheric model (AIM) to use it ; add a "slab ocean" component.
644    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
645    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
646    o extending useSingleCpuIO option to work with new exch2 I/O format
647      - old-style, missing-tile I/O is still accessible by defining CPP
648        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
649    o monitor package can write to NetCDF files and/or STDOUT
650    o fix re-definition bug in MNC_GRID_INIT_ALL()
651    o doc/api_reference added
652      - a framework for building an API Reference Manual using all
653        the "protex" comments embedded in the code
654      - see pkg/generic_advdiff, pkg/mnc for examples
655    o MNC:
656      - make myThid the last argument for all subroutines
657      - new default for the grid files: NO halos
658      - add useMNC and other run-time flags
659      - separate per-file-group handling of the unlimited dimension
660      - early initialization of MNC w/ flags read at the eeboot stage
661        and lookup tables set in initialize_fixed
662      - write all MNC output to a freshly-created directory
663    o thermodynamics sea-ice (thsice) is now tested with testreport.
664    o test exp. advect_cs: use the standard cs32 grid ; update output.
665    o Added functionality to grdchk:
666      pick global i,j,k position (or nearest wet) where to perform check.
667    
668    checkpoint52l_post
669    o new land formulation:
670      a) use ground enthalpy as prognostic variable to ensure exact
671         energy conservation.
672      b) account for water temperature and for latent heat of freezing
673         in all processes (rain, run-off, ground storage)
674      c) compute surface and ground temperature implicitly.
675    o aim_v23 modification for new land model:
676      a) Treat separately land / ocean / sea-ice surface fluxes
677         to allow implicit computation of land & sea-ice surface temp.
678      b) add snow precipitation.
679    checkpoint52l_pre
680    
681    o fix problem (when 1 tile is empty) in min/max monitor.
682    o fix bug in timeAve (u,vZetatave in common block)
683    o no restoring terms under ice for pkg/seaice
684    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
685    o bug fix for pkg/seaice pickups
686    o change MNC call locations and add coordinate attributes
687    o mask vorticity at the corner ; affects global_ocean.cs output
688    o fix ini_curvilinear_grid ; test CS experiments with mpi
689    o aim.5l_cs: modify sea-ice fraction input file ; update output
690    o exf: Adding simple range check routine for exf fields after read
691    
692    checkpoint52k_post
693    o removed top-level directory "diags"
694      - we migrated these functions to pkg/timeave a long time ago
695    o fixed bug introduced in pkg/monitor
696    o accuracy ctrlprec = 32 insuffient for gradient checks using
697      averaged fields (I/O via cost_averages)
698      -> use ctrl.h in active_file*.F to control I/O precision.
699    o paramter list of CALL ADTHE_MAIN_LOOP
700    o added initial do_the_model_io to ecco
701    o set all ...Freq to zero after cost_final
702      taveFreq, dumpFreq, pChkptFreq
703    o MAIN and ECCO differentiability restored
704    
705    checkpoint52j_post
706    o fix nchklev in tamc.h for global_ocean...
707    o Bringing flow and store directives up-to-date
708    o Really weird thing!
709      call do_the_model_io from the_main_loop with parameters
710      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
711      TAF places a faulty re-call of initialise_varia
712      after cost_final call which should not be there!
713    checkpoint52j_pre
714    
715    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
716      error messages
717    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
718    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
719      debug output
720    o modfied mdsio_writefield.F to handle non-global files under exch2
721    o update AIM Cubed-Sphere exp (aim.5l_cs):
722      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
723    o update AIM Equatorial Channel exp:
724      use standard aim_v23 pkg and change the SST fields to be more realistic.
725    o globalFile now works with exch2
726    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
727      mon_vort3.F to make exch2 friendly with >1 tile per cube face
728    o limit timeave output for hi-res integrations
729    
730    checkpoint52i_post
731    o removed CPP_EEOPTIONS.h from verification/*/code
732    o updated the tiling for global_ocean_pressure
733    checkpoint52i_pre
734    
735    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
736      the old pkg/aim).
737    
738    checkpoint52h_pre
739    o shortened offending lines in exch2_send_rx?.template
740    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
741    o genmake2: add build & execute test for NetCDF code
742    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
743      old grid files, moved CPP_EEMACROS.h to pkg/exch2
744    o added useSingleCPUIO flag to monitor.F and mon_out.F
745    o added temporary hack for sea-ice dynamics on the cube:
746      metric terms are ignored and it is assumed that
747      there is no sea-ice on cube faces 1, 2, 4, and 5.
748    
749    checkpoint52f_post
750    o added exch2 cube routines to pkg/exch2
751    o modified hs94.cs-32x32x5 to use it
752    o added new grid files to hs94.cs-32x32x5
753    checkpoint52f_pre
754    
755    checkpoint52e_post
756    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
757      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
758    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
759      to work with implicit vertical advection and AB ;
760    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
761    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
762     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
763    checkpoint52e_pre
764    
765    o fix bug in impldiff when Nr=1 or Nr=2.
766    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
767    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
768    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
769      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
770    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
771    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
772    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
773    
774    checkpoint52d_post
775    o re-tiled many expts to allow comparison in multi-processor mode
776      - updated output accordingly
777      - changed hs94.128x64x5 to use intial T from file rather than use the
778        random number generator
779    o add infrastructure in model routines for fizhi and gridalt packages
780    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
781    o changes to permit hi-res, cubed-sphere, configuration
782      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
783      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
784      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
785        of surface winds for the cube
786      (A verification experiment, based on global_ocean.cs32x15, but with
787       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
788       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
789       complete with example surface forcing files and matlab scripts to look
790       at the output and compare it with that of global_ocean.cs32x15.)
791    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
792       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
793       to conform to the common rule.
794    o check-in the first version of the coupler + interfaces for multi-components
795       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
796       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
797       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
798       - ocean and atmos. share the same horizontal grid (no interpolation).
799       - exchanges between component and coupler is done in forward_step
800    o new verification experiment, cpl_aim+ocn:
801       coupled ocean - AIM atmosphere on cs32 grid.
802    
803    checkpoint52d_pre
804    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
805    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
806    
807    checkpoint52c_post
808    o Fixing OPTIONS files for use of exf:
809      - ALLOW_ECCO not needed
810      - ECCO_CPPOPTIONS.h should not be included from
811        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
812        as has been the case in the past
813      - All cal/exf related options are currently set in
814        single header file. Should remain so until we
815        agree on a consistent new policy.
816    o Removed all CPP options for cal package.
817      cal has no more CPP options.
818    o modified STOREs in GAD_ADVECTION
819    o corrected key comp. for passkey
820    
821    checkpoint52b_post
822    o new version: "thsice" of thermodynamic sea-ice pkg:
823     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
824     - modify fluxes but do not change theta directly;
825     - light cleaning of bulk_force pkg (still needed with thsice).
826     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
827       + output_thsice.txt to test thsice & bulk_force pkgs.
828    o put back grid & coriolis monitor output.
829    checkpoint52b_pre
830    
831    o call "do_the_model_io" at the beginning (=> dump initial state)
832    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
833    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
834      (need info on NUMBER_OF_PTRACERS)
835    o missing PTRACERS headers in some routines
836    o default tamc.h in pkg/autodiff supposed to crash
837      to ensure proper customization
838    
839    checkpoint52a_post
840    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
841      - moved surfaceTendencyTice from pkg/seaice to main code
842      - subroutine FREEZE_SURFACE now limits only surface temperature
843        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
844        => new output.txt for global_ocean.cs32x15 & global_with_exf
845      - keep the old version of FREEZE for backward compatibility;
846        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
847      - corresponding modifs for TAF directives
848    o added surface flux output variables to TIMEAVE_STATVARS

855    o some bug fixes for #undef REAL4_IS_SLOW
856    
857    checkpoint52 = ecco_c52_e35
858    o after testing adjoints of checkpoint51u_post
859    
860    checkpoint51u_post
861    o this is the post-merge tag of the ecco-branch
862      (needs another clean checkout and re-testing)
863    o various natl_box_adjoint configs and results
864      but no input fields
865    o obcs adjoint not yet merged!
866    o adding ECCO global 1x1 and 2x2 degree configs
867    o updated/extended some store directives for seaice
868    o pkg/ecco now containes ecco-specific part of cost function
869    o top level routines the_main_loop, forward_step
870      supersede those in model/src/
871      previous input data.cost now in data.ecco
872      (new namelist ecco_cost_nml)
873    o in ctrl/ cleaned some cross-dependencies and updated CPP options
874    
875    checkpoint51t_post
876    o this is the pre-merge tag of the ecco-branch
877    
878    checkpoint51s_post
879    o cleanup: removed various obsolete #define-s
880    o pkg/grdchk
881      - renamed 'ph-grd 3' to 'grad-res'
882      - merged from ecco-branch
883        (remaining bug fixes for obcs gradient checks)
884      - additional high-precision output for testreport
885        (grep for 'precision_grdchk_result')
886    
887    checkpoint51r_post
888    o cleaned up or removed CPP_OPTIONS.h files
889    o updated results for some of the tests to reflect the new
890      optfiles (-ieee: -O0 instead of -O3)
891    
892    checkpoint51q_post
893    o cd_code:
894      - moved cd_scheme.F -> cd_code_scheme.F
895      - separate read_checkpoint from cd_code_ini_vars.F
896      - separated cd_code part from write_checkpoint
897      - updated AD_SOURCE, generated .flow
898      - added CD_CODE_VARS.h to the_main_loop
899      - Moving cd_code specific store dir.s to pkg/cd_code
900    o ctrl package totally restructured
901      - pack/unpack now optional and decoupled from
902        xx_/adxx_ I/O
903      - ctrl_pack/unpack cleaned
904        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
905      - confined inclusion of AD_CONFIG.h to where necessary.
906    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
907    
908    checkpoint51p_post
909    o create initial cd_code package
910      - WARNING: the initialization of fields within packages
911        is broken because INI_FIELDS (where READ_CHECKPOINT is
912        called) is called *before* PACKAGES_INIT_VARIABLES.
913        This seems to be backwards since
914        1) its important to initially zero the entire field including
915           the "halo" region
916        2) zeroing needs to be done *before* reading pickup info
917           and the pickup call might or might not happen in any
918           particular run
919      - this needs an overhaul for R2
920    o cleanup verification/*/code/GMREDI_OPTIONS.h
921    o cleanup testreport
922    
923    checkpoint51o_post
924    o bringing AD-related verif's up to date with genmake2

934        change rho -> rho-rhoConst
935      - replace call find_rho to find_rhonum
936    o initialisation of rFlx extended to full array (required by TAF)
937      and shifted to thermodynamics
938    o removed PTRACERS.h in ptracers routine
939    o added surfacetendencyPtr to S/R parameter list pracers_forcing

958         global_ocean.cs32x15, and global_with_exf)
959    o added surface flux output variables to TIMEAVE_STATVARS
960    
961    checkpoint51n_pre
962    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

1129    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1130    o AIM: use true log-P extrapolation for near surface temp (= as in
1131        F.Molteni paper) ; update aim.5l_cs output.
1132    o New variable in PARM03 for more flexible pickups
1133    o somewhat cleaned package initialisation sequence for
1134      ctrl/ cost/ ecco/ in packages_... routines
1135    
1136    checkpoint50g_post
1137    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1138      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1139      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1140        made the default because of faster convergence than ADI
1141    
1142    checkpoint50f_post
1143    o exf totally restructured

1162     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1163       nearly a copy of kpp_transport_s
1164     - there is no analogue to SurfaceTendencyS, so I have to use
1165       gPtr(of the surface layer) instead
1166    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1167    checkpoint50e_pre

1179    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1180    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1181    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1182    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1183    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1184    
1185    checkpoint50c_pre
1186    Merging from release1_p13:
1187    o bug fix for pkg/seaice dynamic solver
1188    o Added SEAICE_initialHEFF to pkg/seaice
1189    
1190    checkpoint50b_post
1191    o store u*,v* in gU,V instead of in guNm1,gvNm1
1192    o in order to put the momForcing out of the Adams-Bashforth:
1193      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1194      to timestep.F
1195    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1196    o re-generate output for highly sensitive test-exp:
1197       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1198    
1199    checkpoint50b_pre
1200    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1201    o corrected CPP option mismatch in exf_Bulk... functions for case
1202      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1203    
1204    checkpoint50a_post
1205    o Bug fix for merging between c50 and KPP.
1206      ikey was passed from thermodynamics to kpp_calc via
1207      common block rather than being recomputed in kpp_calc,
1208      in contradiction with new key itdkey.
1209      New key ikppkey created, and tamc.h headers updated.
1210    
1211    checkpoint50
1212    - 2nd step of merge with ecco-branch:
1213      merge changes in ecco-branch back into main trunk
1214    - bug fix in find_alpha
1215    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1216    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1217    - merged some sliced AD support routines
1218    
1219    checkpoint49
1220    merged from ecco-branch:
1221    o exf:
1222      - Enable initialisation of forcing fields to constant
1223        (runtime) values.
1224      - in exf_getffields.F
1225        Reduce i-/j-loop to interior domain, discarding overlaps.
1226        That also fixes wrong TAF-key computations for key_1, key_2
1227        with bulf formulae.
1228      - exf_init.F modify #ifdef for exf_init_evap
1229      - exf_getffieldrec.F, ctrl_getrec.F
1230        The following INT-usages are not safe:
1231          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1232          fldcount = int(fldsecs/fldperiod) + 1
1233        and were modified.
1234    o autodiff: checkpoint_lev...
1235      - updated storing for bulk formulae (some arrays were missing)
1236      - added state for seaice package
1237      - synchronized with main branch
1238    o DIVA:
1239      Modif.s in
1240      - the_main_loop.F
1241      - the_model_main.F
1242      and added cost_final_restore.F cost_final_store.F
1243      o With these changes, it is possible to fully separate
1244        the first forward run to compute the cost function (mdthe_main_loop)
1245        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1246        into separate model executions.
1247        This enables better tuning of DIVA to given queue sizes.
1248      o Loss of cost function value in consecutive DIVA runs is
1249        fixed by storing to 'costfinal' file.
1250      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1251        beginning/end of adjoint integration is accounted for.
1252      The current changes apply to TAF-1.4.26.
1253      TAF has one remaining bug, requiring one manual change
1254      (see MITgcm manual).
1255    o cal: synchronized between MAIN and ecco-branch
1256    
1257    checkpoint48i_post
1258    o Changes to restore differentiability of code w.r.t. previous tag
1259      (mostly adding new routines to make list and replacing
1260      pressure by totPhiHyd).
1261    o Updated and merged grdchk package
1262      - has both ADM and TLM checks
1263      - works for single- and multi-proc.
1264      - output cleaned
1265      - worked successfully for parallel DIVA
1266    o genmake:
1267      - Adding -platform=SP4
1268      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1269    o Modif. for DIVA:
1270      ctrl_unpack should not be called in intermediate DIVA interval.
1271      (similar thing would apply for active files such as
1272      tbar, sbar, psbar, which should not be reinitialised;
1273      only relevant for ecco-branch)
1274    
1275    checkpoint48h_post
1276    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1277    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1278    o Added SEAICE_initialHEFF to pkg/seaice
1279    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1280    
1281    checkpoint48g_post
1282    --- EOS:
1283    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1284      store total Potential in totPhyHyd for diagnostics & EOS.
1285    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1286    --- Pressure/geopotential gradient:
1287    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1288    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1289      ( changes results of global_ocean_pressure )
1290    o NLFS + z-coord.: add eta*Rho' contribution.
1291    o accurate phiHyd when using interface-W at the middle between 2 centers
1292     ( changes results of ideal_2D_oce )
1293    o includes r* 2nd term in potential gradient.
1294    
1295    checkpoint48f_post
1296    Merging from release1_p12:
1297    o Modifications for using pkg/exf with pkg/seaice
1298      - improved description of the various forcing configurations
1299      - added basic radiation bulk formulae to pkg/exf
1300      - units/sign fix for evap computation in exf_getffields.F
1301      - updated verification/global_with_exf/results/output.txt
1302    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1303      (SBO) core products, including oceanic mass, center-of-mass,
1304      angular, and bottom pressure (see pkg/sbo/README.sbo).
1305    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1306      to avoid negative values in shallow regions.
1307      - updated verification/natl_box/results/output.txt
1308      - updated verification/lab_sea/results/output.txt
1309    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1310    o Added useSingleCpuIO option (see PARAMS.h).
1311    o Updated useSingleCpuIO option in mdsio_writefield.F to
1312      work with multi-field files, e.g., for single-file pickup.
1313    o pkg/seaice:
1314      - bug fix in growth.F: QNET for no shortwave case
1315      - added HeffFile for specifying initial sea-ice thickness
1316      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1317    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1318      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1319    o pkg/seaice:
1320      - adjoint-friendly modifications
1321      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1322    
1323    checkpoint48e_post
1324    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1325    o dynamics: change definition of computational domain & adapt mom_fluxform
1326      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1327    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1328        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1329        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1330        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1331        inverted_barometer solid-body.cs-32x32x1
1332      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1333    
1334    checkpoint48d_post
1335    o in preparation for r*:
1336     a) use pre-computed gradient of hydrostatic potential:
1337        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1338     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1339        => affects results of glob_oce_pressure (different truncation error)  
1340      update output.txt of ideal_2D_oce & global_ocean_pressure
1341    
1342    checkpoint48d_pre
1343    o in preparation for r*:
1344      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1345      pass the 2 comp. of the grad. as arguments to momentum S/R.
1346      but for the moment, only used if it does not change the results.
1347    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1348    
1349    checkpoint48c_post
1350    Modifications in treatment of initial flux forcing controls
1351    to avoid extra storing of flux fields.
1352    
1353    checkpoint48c_pre
1354    o Added tidal_basin_2d experiment (currently 1D!)
1355    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1356    
1357    checkpoint48b_post
1358    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1359     (modification to pressure gradient not yet implemented)
1360    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1361      (for U & V) that are used for vertical advection of momentum.
1362    
1363    checkpoint48a_post
1364    o In preparation for r*, use temp. array to compute vertical transport
1365       in flux-form momentum pkg. => change results of few test-exp.
1366      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1367                        lab_sea, natl_box & plume_on_slope
1368    
1369    checkpoint48
1370    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1371    
1372    checkpoint47j_post
1373    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1374    o moved adexch from forward_step to addummy_in_stepping
1375    o added exch in ctrl_map_...
1376    o aveFreq.=0. at end of cost_final to avoid overwrite in
1377      reverse checkpointing loop
1378    o Yet more changes in gmredi:
1379      * adgmredi_calc_tensor
1380        avoiding all recomputation of gmredi_slope_limit
1381      * adgmredi_x/y/rtransport
1382        added flag for excessive storing to avoid recomp. of
1383        u/v/rtans, dTdx/y/z
1384        -> this is not really necessary and very memory-consuming
1385      * adgmredi_slope_psi:
1386        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1387      * gmredi_slope_limit
1388        re-activated full calculation of taperfct for case 'ac02'
1389    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1390    
1391    checkpoint47i_post
1392    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1393    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1394      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1395    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1396    o gmredi: fix few bugs.
1397    
1398    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1399    This will be a good checkpoint to plug into the ecco-branch.
1400    o few modif.'s to get latest version adjointed
1401      (mainly kick out code in ini_linear_phisurf)
1402    o modif's to run adjoint with exactConserv
1403    o case GM_BOLUS_ADVEC should be cleaned
1404      S/R gmredi_slope_psi should be cleaned
1405    o verification/carbon now has exactConserv=.TRUE.
1406    
1407    checkpoint47g_post
1408    o time-average AIM output: becomes independent from statvars time-average
1409      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1410    o After TAF bug fix:
1411      Tested adjoint of gmredi package.
1412      Tests were done with checkpoint47 rather than with latest
1413      checkpoint47f_post since the latter is broken for the adjoint
1414      verification/carbon/ contains both ADM and TLM gradient checks.
1415    Here they are, before they get changed/lost/stolen.
1416    Mostly modif.'s to fix numerical sensitivities.
1417    Gradient checks OK for
1418    - GM_taper_scheme:
1419      * clipping
1420      * ac02
1421      * linear
1422      * glw91
1423      * dm95
1424      * ldd97
1425    - GMREDI_OPTIONS:
1426      * GM_VISBECK_VARIABLE_K
1427      * GM_NON_UNITY_DIAGONAL
1428      * GM_EXTRA_DIAGONAL
1429      * GM_BOLUS_ADVEC
1430    in conjunction with data.gmredi parameters to be checked in
1431    in a few minutes under verification/carbon/code/
1432    
1433    checkpoint47f_post
1434    Merging from release1_p10:
1435    o modifications for using pkg/exf with pkg/seaice
1436      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1437        and SEAICE_EXTERNAL_FLUXES
1438      - pkg/exf CPP options EXF_READ_EVAP and
1439        EXF_NO_BULK_COMPUTATIONS
1440      - usage examples are Experiments 8 and 9 in
1441        verification/lab_sea/README
1442      - verification/lab_sea default experiment now uses
1443        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1444    
1445    checkpoint47e_post
1446    o created a tag prior to creating a branch
1447    
1448    checkpoint47d_post
1449    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1450      at the bottom boundary had an erroneous half slip boundary condition
1451    o added bottom drag and no slip boundary condition capabilities to
1452      oceanic pressure coordinates code
1453    o added new verification experiment global_ocean_pressure, this experiment is
1454      also described in the tutorial section of the manual
1455    checkpoint47d_pre
1456    
1457    checkpoint47c_post
1458    o Added a verification experiment for a global cubed-sphere ocean run
1459      -  verification/global_ocean.cubed32x32x30
1460      -  uses pkg/therm_seaice and pkg/bulk_forcing
1461    
1462    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1463    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1464      when using P-coordinate; only implemented for atmospheric config.
1465    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1466      NOTES: requires option NONLIN_FRSURF to be "#define".
1467    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1468    
1469    checkpoint47b_post
1470    Merging from release1_p9:
1471    o pkg/seaice
1472      - removed GOTO's and added taf directives
1473      - double precision constants to reduce the g77 (Linux)
1474        to F77 (SGI) differences reported in release1_p8
1475    o tools/genmake
1476      - added SGI options
1477    o verification/testscript
1478      - updated to that of checkpoint47a_post
1479    o verification/global_ocean.90x40x15/input/eedata
1480      - modified for SGI f77 compatibility
1481    o verification/lab_sea
1482      - added description of sea-ice model
1483      - added missing matlab routines
1484      - added test of thermodynamics parallelization
1485    
1486    checkpoint47a_post
1487    o new pkg: aim_v23
1488     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1489       for now, keep the same surface forcing as before.
1490     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1491     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1492     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1493    o add diagnostic of surface correction term in monitor output
1494    
1495    o bulk_force and therm_seaice
1496    - Two packages:  bulk_force (Bulk forcing)
1497      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1498    - Earlier integration from Stephaine Dutkiewicz
1499      and Patrick Heimbach.
1500    - Two ifdef statements for compile time,
1501       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1502    
1503    checkpoint47
1504    differentiable version of checkpoint46n_post
1505    o bug fix in quasihydrostaticterms
1506    o * "clean" adjoint code (in terms of extensive recomputations)
1507        can now be obtained for all GMREDI options (i.e. for
1508        - GM_VISBECK_VARIABLE_K
1509        - GM_NON_UNITY_DIAGONAL
1510        - GM_EXTRA_DIAGONAL
1511        - GM_BOLUS_ADVEC )
1512      * However, wrong gradient check problem remains unsolved.
1513      * New CPP options have been introduced for different
1514        tapering schemes
1515    o external_fields_load now part of differentiation list
1516    o pressure needs multiple storing;
1517      would be nice to have store_pressure at beginning or
1518      end of forward_step, e.g. by having phiHyd global (5-dim.)
1519      (NB: pressure is needed for certain cases in find_rho,
1520      which is also invoked through convective_adjustment).
1521    o recomputations in find_rho for cases
1522     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1523    o #define ATMOSPHERIC_LOADING should be differentiable
1524    o ini_forcing shifted to begining of initialise_varia
1525    o Incorporating QNVS line search routines into MITgcm
1526      (this is separate code, and therefore not under pkg)
1527      lsopt/, optim/
1528    o Updated verification/carbon/
1529      - #define GM_VISBECK_VARIABLE_K
1530      - GM_taper_scheme    = 'ldd97'    
1531    
1532    checkpoint46n_post
1533    Merging from release1_p8:
1534    o verification/natl_box:
1535      updating new external_fields_load routine
1536    o New package: pkg/seaice
1537      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1538      The sea-ice code is based on Hibler (1979-1980).
1539      Two sea-ice dynamic solvers, ADI and LSR, are included.
1540      In addition to computing prognostic sea-ice variables and diagnosing
1541      the forcing/external data fields that drive the ocean model,
1542      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1543      The implied surface heat flux is then stored in variable
1544      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1545      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1546      non-local transport term.  Because this call precedes model
1547      thermodynamics, temperature under sea-ice may not be "exactly" at
1548      the freezing point by the time theta is dumped or time-averaged.
1549      N.B.: fairly large differences in accuracy occur across
1550            different platforms/compilers; comparison between
1551            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1552            generated output gives:

1559      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1560    o GAD:
1561      - generated new common blocks to account for call of
1562        same gad routines with differing traceridentities
1563        (needed to modify tracerIdentity indices in GAD.h)
1564      - generated separate common blocks for case useCubedSphereExchange
1565        (Department of Futurology)
1566      - parameter lists to gmredi_?transport: added tracerIdentity
1567      - added new key indices to tamc.h
1568    o external_fields_load:
1569      - added this routine to TAF list
1570      - needed to make some common blocks global and additional storing
1571        along the same lines as exf package (checkpoint_lev?_directives.h)
1572    o exf:
1573      updated external forcing package
1574      - bug fixes carried over from ecco-branch
1575        (missing OBCS_OPTIONS.h in two routines)
1576      - enable easy to use "no forcing".
1577      - added exf I/O for atmospheric loading
1578      - added exf I/O for runoff data
1579      - transfered scaling between exf <-> MITgcm to exf namelist
1580    o Adding new verification experiment global_with_exf.
1581      This verification experiment is almost identical to the
1582      global_ocean.90x40x15 experiment, except that it uses
1583      the exf (and cal) package instead of the
1584      external_fields_load routine (cf README file).
1585    
1586    checkpoint46m_post
1587    o modified testscript to return -- when there are no lines of "%MON" output
1588    o added new flag "quasiHydrostatic" for QH mode
1589      and new routine quasihydrostaticterms()
1590    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1591      New routine: mom_u_coriolis_nh()
1592    o fixed sign of non-hydrostatic metric terms in u and v equations.
1593      Depend on correct sign of gravitySign.
1594    o added work.pc* to .cvsignore in aim directories using ifc
1595    o introduced flag for controllin non-hydrostatic metric terms
1596    o removed gravitySign from PARM04
1597    o switched to g77/ifc from pgf77 in aim experiments
1598    
1599    checkpoint46l_post
1600    o made convective adjustment work with pressure coordinates:
1601     - changed the direction of k-loop in convective_adjustment.F for the
1602       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1603     - adjusted the reference pressure k-index in convective_adjustment.F
1604     - adjusted the convection condition in convect.F (in analogy to
1605       calc_ivdc.F)
1606     - convective_adjustment no longer computes anything on the halos
1607     - removed the warnings about negative salinity from find_rho.F and
1608       find_alpha.F; instead the new routine look_for_neg_salinity, called
1609       at the beginning of find_rho, find_alpha, and find_beta, does a
1610       check of the entire slice, if CPP-option
1611       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1612    checkpoint46l_pre
1613    
1614    checkpoint46k_post
1615    o fixed the verification/global_ocean.90x40x15 experiment:
1616     - new bathymetry (the world according to A., JMC, and M.)
1617     - new initial fields and forcing fields (*.bin files)
1618     - new POLY3.COEFFS (for the next release one should switch to a full
1619       equation of state: JMD95P or MDJWF)
1620     - fixed several errors and redundancies in the data file
1621     - experiment uses looped cells
1622     - added matlab directory with diagnostic scripts for plotting of output
1623    
1624    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1625     - read AIM physics parameters from a file (data.aimphys)
1626     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1627    
1628    checkpoint46j_post
1629    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1630    o move wVel computation at the end of the time step, in S/R integr_continuity
1631    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1632    o update timeave pkg for wVel diagnostic.
1633    checkpoint46j_pre
1634    
1635    checkpoint46i_post
1636    o Clean up AIM package (and keep the results unchanged):
1637      include CPP_OPTION and use IMPLICT NONE in all routines ;
1638      declare all the variables _RL ; use _d 0 for all numerical constants.
1639      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1640    
1641    checkpoint46h_post
1642    o cleaned up the use of rhoNil and rhoConst.
1643      - rhoNil should only appear in the LINEAR equation of state, everywhere
1644        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1645        and the dynamical equations are all divided by rhoConst
1646    o introduced new parameter rhoConstFresh, a reference density of fresh
1647      water, to remove the fresh water flux's dependence on rhoNil. The default
1648      value is 999.8 kg/m^3
1649    o cleanup up external_forcing.F and external_forcing_surf.F
1650      - can now be used by both OCEANIC and OCEANICP
1651    checkpoint46h_pre
1652    
1653     Added code to convert surface volume flux (fresh water) into
1654     a mass flux when using P coordinates in the ocean (OCEANICP).
1655     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1656    
1657    checkpoint46g_post
1658    o Include a new diagnostic variable phiHydLow for the ocean model
1659      - in z-coordinates, it is the bottom pressure anomaly
1660      - in p-coordinates, it is the sea surface elevation
1661      - in both cases, these variable have global drift, reflecting the mass
1662        drift in z-coordinates and the volume drift in p-coordinates
1663      - included time averaging for phiHydLow, be aware of the drift!
1664    o depth-dependent computation of Bo_surf for pressure coordinates
1665      in the ocean (buoyancyRelation='OCEANICP')
1666      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1667        Theta, Salinity, and Pressure in the parameter list. This routine is
1668        presently contained in find_rho.F. This routine does not give the
1669        correct density for 'POLY3', which would be a z-dependent reference
1670        density.
1671    o cleaned up find_rho
1672      - removed obsolete 'eqn' from the parameter list.
1673    o added two new verification experiments: gop and goz
1674      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1675    checkpoint46g_pre
1676    
1677    checkpoint46f_post
1678    o Enable tangent linear (forward mode) gradient checks:
1679      - extended active file handling to g_... files
1680      - added TANGENT_SIMULATION to theSimulationMode
1681      - extended grdchk package accordingly
1682    o added tangent linear setup in verification/carbon/code_ftl
1683    o added adjoint setup in verification/front_relax/code_ad
1684    
1685    checkpoint46e_post
1686    o Added new equation of state -> MDJWF
1687      - EOS of McDougall et al., 2002, JAOT, submitted
1688      - caveat: the equation of state is only valid for a smaller (more
1689        realistic?) range of values than JMD95P/Z and UNESCO
1690      - added masks to the calculation of pressure in store_pressure
1691      - added more check values for density in check_eos (ini_eos.F), some of
1692        the old check values are out of the range of the MDJWF-eos, so don't
1693        expect perfect matches for those
1694    checkpoint46e_pre
1695    
1696    checkpoint46d_post
1697    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1698      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1699      case of pressure coordinates. eosType='JMD95Z' in
1700      combination with buoyancyRelation='OCEANICP' now causes an error.
1701    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1702      in find_alpha/beta.
1703    checkpoint46d_pre
1704    
1705    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1706      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1707    
1708    checkpoint46c_post
1709    o Changes necessary for ocean in p-coordinates
1710     -  Added new buoyancy relation = 'OCEANICP'
1711     -  Added new parameters = gravitySign (this used to be contained inside
1712        the factor dRdZ which I added when we first switched to R coordinates).
1713     X GM/Redi is not compatible (yet)
1714     X bottom drag and no-slip need to be debugged.
1715    checkpoint46c_pre
1716    
1717    checkpoint46b_post
1718    o Added new equation of state -> JMD95Z and JMD95P
1719      - EOS of Jackett and McDougall, 1995, JAOT
1720      - moved all EOS parameters into EOS.h
1721      - new routines ini_eos.F, store_pressure.F
1722    o Added UNESCO EOS, but not recommended because it requires
1723      in-situ temperature (see JMD95)
1724    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1725      unesco.f to be used with POLY3
1726    checkpoint46b_pre
1727    
1728    checkpoint46a_post
1729    o Added (atmospheric) pressure loading
1730      - new field in FFIELDS.h, etc...
1731      - new cpp flag ATMOSPHERIC_LOADING
1732    o Changed hFacC to _hFacC in calc_phi_hyd.F
1733    o Added SHORTWAVE_HEATING to some files for consistency
1734    checkpoint46a_pre
1735    
1736    checkpoint46
1737    further merges from release1_p5
1738    o new ctrl package
1739      - adopted from ECCO environment to enable optimization
1740      - added Eliassen Palm fluxes to controls
1741    o added Eliassen Palm flux controls to gradient check package
1742    o cost package
1743      - Compatible with new ctrl package
1744      - added Eliassen Palm cost hooks
1745      - modif's of existing cost functions
1746    o Adjoint-related bug fixes in kpp:
1747      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1748      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1749    o autodiff package
1750      - flow directives:
1751        + new for S/R do_the_model_io
1752        + enhanced for S/R checkpoint
1753        + new gmredi.flow
1754      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1755        disable adcommon.h/g_common.h by default.
1756      - fixed problem for adjoint of global_max
1757    o modified verification/carbon/
1758    o New setup for adjoint of global_ocean
1759    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1760    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1761    o incorporated hooks for sponge layer code (external_forcing.F)
1762    
1763    checkpoint45d_post
1764    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1765    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1766      (affects plume_on_slope "cg2d" output)
1767    o add new parameter deltaTfreesurf for free-surface time stepping
1768    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1769  o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B  o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1770  o change phiMin in exp1 (to agree with documentation)  o change phiMin in exp1 (to agree with documentation)
1771  o add new flags:  o add new flags:
