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

841    o some bug fixes for #undef REAL4_IS_SLOW
842    
843    checkpoint52 = ecco_c52_e35
844    o after testing adjoints of checkpoint51u_post
845    
846    checkpoint51u_post
847    o this is the post-merge tag of the ecco-branch
848      (needs another clean checkout and re-testing)
849    o various natl_box_adjoint configs and results
850      but no input fields
851    o obcs adjoint not yet merged!
852    o adding ECCO global 1x1 and 2x2 degree configs
853    o updated/extended some store directives for seaice
854    o pkg/ecco now containes ecco-specific part of cost function
855    o top level routines the_main_loop, forward_step
856      supersede those in model/src/
857      previous input data.cost now in data.ecco
858      (new namelist ecco_cost_nml)
859    o in ctrl/ cleaned some cross-dependencies and updated CPP options
860    
861    checkpoint51t_post
862    o this is the pre-merge tag of the ecco-branch
863    
864    checkpoint51s_post
865    o cleanup: removed various obsolete #define-s
866    o pkg/grdchk
867      - renamed 'ph-grd 3' to 'grad-res'
868      - merged from ecco-branch
869        (remaining bug fixes for obcs gradient checks)
870      - additional high-precision output for testreport
871        (grep for 'precision_grdchk_result')
872    
873    checkpoint51r_post
874    o cleaned up or removed CPP_OPTIONS.h files
875    o updated results for some of the tests to reflect the new
876      optfiles (-ieee: -O0 instead of -O3)
877    
878    checkpoint51q_post
879    o cd_code:
880      - moved cd_scheme.F -> cd_code_scheme.F
881      - separate read_checkpoint from cd_code_ini_vars.F
882      - separated cd_code part from write_checkpoint
883      - updated AD_SOURCE, generated .flow
884      - added CD_CODE_VARS.h to the_main_loop
885      - Moving cd_code specific store dir.s to pkg/cd_code
886    o ctrl package totally restructured
887      - pack/unpack now optional and decoupled from
888        xx_/adxx_ I/O
889      - ctrl_pack/unpack cleaned
890        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
891      - confined inclusion of AD_CONFIG.h to where necessary.
892    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
893    
894    checkpoint51p_post
895    o create initial cd_code package
896      - WARNING: the initialization of fields within packages
897        is broken because INI_FIELDS (where READ_CHECKPOINT is
898        called) is called *before* PACKAGES_INIT_VARIABLES.
899        This seems to be backwards since
900        1) its important to initially zero the entire field including
901           the "halo" region
902        2) zeroing needs to be done *before* reading pickup info
903           and the pickup call might or might not happen in any
904           particular run
905      - this needs an overhaul for R2
906    o cleanup verification/*/code/GMREDI_OPTIONS.h
907    o cleanup testreport
908

920        change rho -> rho-rhoConst
921      - replace call find_rho to find_rhonum
922    o initialisation of rFlx extended to full array (required by TAF)
923      and shifted to thermodynamics
924    o removed PTRACERS.h in ptracers routine
925    o added surfacetendencyPtr to S/R parameter list pracers_forcing

944         global_ocean.cs32x15, and global_with_exf)
945    o added surface flux output variables to TIMEAVE_STATVARS
946    
947    checkpoint51n_pre
948    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

1124      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1125      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1126        made the default because of faster convergence than ADI
1127    
1128    checkpoint50f_post
1129    o exf totally restructured

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

1544    
1545      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1546    o GAD:
1547      - generated new common blocks to account for call of
1548        same gad routines with differing traceridentities
1549        (needed to modify tracerIdentity indices in GAD.h)
1550      - generated separate common blocks for case useCubedSphereExchange
1551        (Department of Futurology)
1552      - parameter lists to gmredi_?transport: added tracerIdentity
1553      - added new key indices to tamc.h
1554    o external_fields_load:
1555      - added this routine to TAF list
1556      - needed to make some common blocks global and additional storing
1557        along the same lines as exf package (checkpoint_lev?_directives.h)
1558    o exf:
1559      updated external forcing package
1560      - bug fixes carried over from ecco-branch
1561        (missing OBCS_OPTIONS.h in two routines)
1562      - enable easy to use "no forcing".
1563      - added exf I/O for atmospheric loading
1564      - added exf I/O for runoff data
1565      - transfered scaling between exf <-> MITgcm to exf namelist
1566    o Adding new verification experiment global_with_exf.
1567      This verification experiment is almost identical to the
1568      global_ocean.90x40x15 experiment, except that it uses
1569      the exf (and cal) package instead of the
1570      external_fields_load routine (cf README file).
1571    
1572    checkpoint46m_post
1573    o modified testscript to return -- when there are no lines of "%MON" output
1574    o added new flag "quasiHydrostatic" for QH mode
1575      and new routine quasihydrostaticterms()
1576    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1577      New routine: mom_u_coriolis_nh()
1578    o fixed sign of non-hydrostatic metric terms in u and v equations.
1579      Depend on correct sign of gravitySign.
1580    o added work.pc* to .cvsignore in aim directories using ifc
1581    o introduced flag for controllin non-hydrostatic metric terms
1582    o removed gravitySign from PARM04
1583    o switched to g77/ifc from pgf77 in aim experiments
1584    
1585    checkpoint46l_post
1586    o made convective adjustment work with pressure coordinates:
1587     - changed the direction of k-loop in convective_adjustment.F for the
1588       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1589     - adjusted the reference pressure k-index in convective_adjustment.F
1590     - adjusted the convection condition in convect.F (in analogy to
1591       calc_ivdc.F)
1592     - convective_adjustment no longer computes anything on the halos
1593     - removed the warnings about negative salinity from find_rho.F and
1594       find_alpha.F; instead the new routine look_for_neg_salinity, called
1595       at the beginning of find_rho, find_alpha, and find_beta, does a
1596       check of the entire slice, if CPP-option
1597       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1598    checkpoint46l_pre
1599    
1600    checkpoint46k_post
1601    o fixed the verification/global_ocean.90x40x15 experiment:
1602     - new bathymetry (the world according to A., JMC, and M.)
1603     - new initial fields and forcing fields (*.bin files)
1604     - new POLY3.COEFFS (for the next release one should switch to a full
1605       equation of state: JMD95P or MDJWF)
1606     - fixed several errors and redundancies in the data file
1607     - experiment uses looped cells
1608     - added matlab directory with diagnostic scripts for plotting of output
1609    
1610    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1611     - read AIM physics parameters from a file (data.aimphys)
1612     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1613    
1614    checkpoint46j_post
1615    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1616    o move wVel computation at the end of the time step, in S/R integr_continuity
1617    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1618    o update timeave pkg for wVel diagnostic.
1619    checkpoint46j_pre
1620    
1621    checkpoint46i_post
1622    o Clean up AIM package (and keep the results unchanged):
1623      include CPP_OPTION and use IMPLICT NONE in all routines ;
1624      declare all the variables _RL ; use _d 0 for all numerical constants.
1625      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1626    
1627    checkpoint46h_post
1628    o cleaned up the use of rhoNil and rhoConst.
1629      - rhoNil should only appear in the LINEAR equation of state, everywhere
1630        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1631        and the dynamical equations are all divided by rhoConst
1632    o introduced new parameter rhoConstFresh, a reference density of fresh
1633      water, to remove the fresh water flux's dependence on rhoNil. The default
1634      value is 999.8 kg/m^3
1635    o cleanup up external_forcing.F and external_forcing_surf.F
1636      - can now be used by both OCEANIC and OCEANICP
1637    checkpoint46h_pre
1638    
1639     Added code to convert surface volume flux (fresh water) into
1640     a mass flux when using P coordinates in the ocean (OCEANICP).
1641     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1642    
1643    checkpoint46g_post
1644    o Include a new diagnostic variable phiHydLow for the ocean model
1645      - in z-coordinates, it is the bottom pressure anomaly
1646      - in p-coordinates, it is the sea surface elevation
1647      - in both cases, these variable have global drift, reflecting the mass
1648        drift in z-coordinates and the volume drift in p-coordinates
1649      - included time averaging for phiHydLow, be aware of the drift!
1650    o depth-dependent computation of Bo_surf for pressure coordinates
1651      in the ocean (buoyancyRelation='OCEANICP')
1652      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1653        Theta, Salinity, and Pressure in the parameter list. This routine is
1654        presently contained in find_rho.F. This routine does not give the
1655        correct density for 'POLY3', which would be a z-dependent reference
1656        density.
1657    o cleaned up find_rho
1658      - removed obsolete 'eqn' from the parameter list.
1659    o added two new verification experiments: gop and goz
1660      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1661    checkpoint46g_pre
1662    
1663    checkpoint46f_post
1664    o Enable tangent linear (forward mode) gradient checks:
1665      - extended active file handling to g_... files
1666      - added TANGENT_SIMULATION to theSimulationMode
1667      - extended grdchk package accordingly
1668    o added tangent linear setup in verification/carbon/code_ftl
1669    o added adjoint setup in verification/front_relax/code_ad
1670    
1671    checkpoint46e_post
1672    o Added new equation of state -> MDJWF
1673      - EOS of McDougall et al., 2002, JAOT, submitted
1674      - caveat: the equation of state is only valid for a smaller (more
1675        realistic?) range of values than JMD95P/Z and UNESCO
1676      - added masks to the calculation of pressure in store_pressure
1677      - added more check values for density in check_eos (ini_eos.F), some of
1678        the old check values are out of the range of the MDJWF-eos, so don't
1679        expect perfect matches for those
1680    checkpoint46e_pre
1681    
1682    checkpoint46d_post
1683    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1684      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1685      case of pressure coordinates. eosType='JMD95Z' in
1686      combination with buoyancyRelation='OCEANICP' now causes an error.
1687    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1688      in find_alpha/beta.
1689    checkpoint46d_pre
1690    
1691    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1692      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1693    
1694    checkpoint46c_post
1695    o Changes necessary for ocean in p-coordinates
1696     -  Added new buoyancy relation = 'OCEANICP'
1697     -  Added new parameters = gravitySign (this used to be contained inside
1698        the factor dRdZ which I added when we first switched to R coordinates).
1699     X GM/Redi is not compatible (yet)
1700     X bottom drag and no-slip need to be debugged.
1701    checkpoint46c_pre
1702    
1703    checkpoint46b_post
1704    o Added new equation of state -> JMD95Z and JMD95P
1705      - EOS of Jackett and McDougall, 1995, JAOT
1706      - moved all EOS parameters into EOS.h
1707      - new routines ini_eos.F, store_pressure.F
1708    o Added UNESCO EOS, but not recommended because it requires
1709      in-situ temperature (see JMD95)
1710    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1711      unesco.f to be used with POLY3
1712    checkpoint46b_pre
1713    
1714    checkpoint46a_post
1715    o Added (atmospheric) pressure loading
1716      - new field in FFIELDS.h, etc...
1717      - new cpp flag ATMOSPHERIC_LOADING
1718    o Changed hFacC to _hFacC in calc_phi_hyd.F
1719    o Added SHORTWAVE_HEATING to some files for consistency
1720    checkpoint46a_pre
1721    
1722    checkpoint46
1723    further merges from release1_p5
1724    o new ctrl package
1725      - adopted from ECCO environment to enable optimization
1726      - added Eliassen Palm fluxes to controls
1727    o added Eliassen Palm flux controls to gradient check package
1728    o cost package
1729      - Compatible with new ctrl package
1730      - added Eliassen Palm cost hooks
1731      - modif's of existing cost functions
1732    o Adjoint-related bug fixes in kpp:
1733      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1734      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1735    o autodiff package
1736      - flow directives:
1737        + new for S/R do_the_model_io
1738        + enhanced for S/R checkpoint
1739        + new gmredi.flow
1740      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1741        disable adcommon.h/g_common.h by default.
1742      - fixed problem for adjoint of global_max
1743    o modified verification/carbon/
1744    o New setup for adjoint of global_ocean
1745    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1746    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1747    o incorporated hooks for sponge layer code (external_forcing.F)
1748    
1749    checkpoint45d_post
1750    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1751    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1752      (affects plume_on_slope "cg2d" output)
1753    o add new parameter deltaTfreesurf for free-surface time stepping
1754    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1755    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1756    o change phiMin in exp1 (to agree with documentation)
1757    o add new flags:
1758     - T,S forcing inside/outside Adams-Bashforth
1759     - turn off temp,salt advection and/or forcing
1760     - for each tracer, define internal flag for multiDimAdvection & A-B
1761    o monitor: change definition of KE to check conservation of Energy
1762    
1763    checkpoint45c_post
1764    o Removed f90 comments ("!")
1765    o Modified initialisations to enable exf package for MITgcm
1766      (without invoking ECCO_PACKAGE).
1767    o modifications to gradient check package (Martin Losch)
1768      - enable centered differences
1769      - modified format of standard output
1770    
1771    checkpoint45b_post
1772    o cleaned exchange calls in cg2d
1773    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1774    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1775      to configure barotropic setup (Martin Losch)
1776    o moved some initialisations within bi,bj loop in dynamics
1777      (TAF flow dependency)
1778    o in initialise_varia, moved call packages_init_variables
1779      before convective_adjustment_init
1780      (corresponding adjustment of TAF tape initialisation).
1781    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1782    
1783    checkpoint45a_post
1784    o compute Rho over the whole domain (extend iMin,jMin indices)
1785    o specific exchange for X-slice domain (case Ny=1)
1786    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1787    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1788    
1789    checkpoint44h_post = checkpoint45
1790    o Fix to restore differentiability:
1791      place at which packages_init_variables is called in
1792      initialise_varia is crucial for reverse control flow.
1793    o modifications in GMRedi to enable stable adjoint
1794      (corresponding modif's in thermodynamics, dynamics)
1795    o added missing hook for sponge layer code in external_forcing
1796    o modified test cost functions
1797    o storing in gad_advection (plus removal of write(0,*)!
1798    o missing headers TR1.h added in convective_adjustment routines
1799    o errorMessageUnit set non-equal zero in eeboot
1800      (conflict on some platforms, e.g. IBM SP3)
1801    o modified carbon verif.
1802    
1803    checkpoint44h_pre
1804    o vertical grid option: allow to put the Interface at the middle between
1805      2 cell-centers ; replace delZ in pkg/kpp by drF.
1806    o GM Advective form: Tracers are advected using the residual transport (=
1807      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1808    
1809    checkpoint44g_post
1810    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1811      results) ; ifdef missing in thermodynamics.F
1812    
1813    checkpoint44f_pre,checkpoint44f_post
1814    o added PTRACERS package
1815      This allows an arbitrary number of passive tracers to be integrated
1816      forward simultaneously with the dynamicaly model.
1817      + Implemented so far:
1818        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1819        - I/O and checkpointing
1820        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1821      + Not implemented so far:
1822        - KPP
1823        - OBCS
1824      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1825        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1826        line in data.pkg.
1827      + This package is disabled by default since it increases storage.
1828    
1829    
1830    o testscript: added -cleanup option
1831    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1832                 b) enable to filter 2D fields.
1833    
1834    checkpoint44e_pre,post
1835    o re-wrote convective adjustment to use pre-calculated weights
1836      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1837      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1838      Original calls to convect() still in place.
1839    
1840    chkpt44d_pre,post
1841    o added missing EXCLUDE_MONITOR flags
1842    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
1843      (incompatible typ in MIN/MAX expressions caused problems
1844      on IBM SP3)
1845    o in genmake added variable MAKEDEPEND
1846      plus resetting for case SunOS
1847    o added timer_stats.c routine for IBM SP3
1848    o removed variables in dynamics
1849    !!! I forgot to create tag chkpt44d_pre !!!
1850    !!! But chkpt44d_pre = chkpt44c_post    !!!
1851    
1852    o real fresh water flux implemented with non-linear free-surface.
1853    
1854  chkpt44c_pre,post  chkpt44c_pre,post
1855  o few fix (mask in shap_s2, EmPmR in external_field_load,  o few fix (mask in shap_s2, EmPmR in external_field_load,
1856    USE_NATURAL_BCS in solve_for_P);    USE_NATURAL_BCS in solve_for_P);
