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

849    o some bug fixes for #undef REAL4_IS_SLOW
850    
851    checkpoint52 = ecco_c52_e35
852    o after testing adjoints of checkpoint51u_post
853    
854    checkpoint51u_post
855    o this is the post-merge tag of the ecco-branch
856      (needs another clean checkout and re-testing)
857    o various natl_box_adjoint configs and results
858      but no input fields
859    o obcs adjoint not yet merged!
860    o adding ECCO global 1x1 and 2x2 degree configs
861    o updated/extended some store directives for seaice
862    o pkg/ecco now containes ecco-specific part of cost function
863    o top level routines the_main_loop, forward_step
864      supersede those in model/src/
865      previous input data.cost now in data.ecco
866      (new namelist ecco_cost_nml)
867    o in ctrl/ cleaned some cross-dependencies and updated CPP options
868    
869    checkpoint51t_post
870    o this is the pre-merge tag of the ecco-branch
871    
872    checkpoint51s_post
873    o cleanup: removed various obsolete #define-s
874    o pkg/grdchk
875      - renamed 'ph-grd 3' to 'grad-res'
876      - merged from ecco-branch
877        (remaining bug fixes for obcs gradient checks)
878      - additional high-precision output for testreport
879        (grep for 'precision_grdchk_result')
880    
881    checkpoint51r_post
882    o cleaned up or removed CPP_OPTIONS.h files
883    o updated results for some of the tests to reflect the new
884      optfiles (-ieee: -O0 instead of -O3)
885    
886    checkpoint51q_post
887    o cd_code:
888      - moved cd_scheme.F -> cd_code_scheme.F
889      - separate read_checkpoint from cd_code_ini_vars.F
890      - separated cd_code part from write_checkpoint
891      - updated AD_SOURCE, generated .flow
892      - added CD_CODE_VARS.h to the_main_loop
893      - Moving cd_code specific store dir.s to pkg/cd_code
894    o ctrl package totally restructured
895      - pack/unpack now optional and decoupled from
896        xx_/adxx_ I/O

899      - confined inclusion of AD_CONFIG.h to where necessary.
900    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
901    
902    checkpoint51p_post
903    o create initial cd_code package
904      - WARNING: the initialization of fields within packages
905        is broken because INI_FIELDS (where READ_CHECKPOINT is
906        called) is called *before* PACKAGES_INIT_VARIABLES.
907        This seems to be backwards since
908        1) its important to initially zero the entire field including
909           the "halo" region
910        2) zeroing needs to be done *before* reading pickup info
911           and the pickup call might or might not happen in any
912           particular run
913      - this needs an overhaul for R2
914    o cleanup verification/*/code/GMREDI_OPTIONS.h
915    o cleanup testreport
916    
917    checkpoint51o_post

928        change rho -> rho-rhoConst
929      - replace call find_rho to find_rhonum
930    o initialisation of rFlx extended to full array (required by TAF)
931      and shifted to thermodynamics
932    o removed PTRACERS.h in ptracers routine
933    o added surfacetendencyPtr to S/R parameter list pracers_forcing

952         global_ocean.cs32x15, and global_with_exf)
953    o added surface flux output variables to TIMEAVE_STATVARS
954    
955    checkpoint51n_pre
956    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

1132      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1133      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1134        made the default because of faster convergence than ADI
1135    
1136    checkpoint50f_post
1137    o exf totally restructured

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

1552    
1553      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1554    o GAD:
1555      - generated new common blocks to account for call of
1556        same gad routines with differing traceridentities
1557        (needed to modify tracerIdentity indices in GAD.h)
1558      - generated separate common blocks for case useCubedSphereExchange
1559        (Department of Futurology)
1560      - parameter lists to gmredi_?transport: added tracerIdentity
1561      - added new key indices to tamc.h
1562    o external_fields_load:
1563      - added this routine to TAF list
1564      - needed to make some common blocks global and additional storing
1565        along the same lines as exf package (checkpoint_lev?_directives.h)
1566    o exf:
1567      updated external forcing package
1568      - bug fixes carried over from ecco-branch
1569        (missing OBCS_OPTIONS.h in two routines)
1570      - enable easy to use "no forcing".
1571      - added exf I/O for atmospheric loading
1572      - added exf I/O for runoff data
1573      - transfered scaling between exf <-> MITgcm to exf namelist
1574    o Adding new verification experiment global_with_exf.
1575      This verification experiment is almost identical to the
1576      global_ocean.90x40x15 experiment, except that it uses
1577      the exf (and cal) package instead of the
1578      external_fields_load routine (cf README file).
1579    
1580    checkpoint46m_post
1581    o modified testscript to return -- when there are no lines of "%MON" output
1582    o added new flag "quasiHydrostatic" for QH mode
1583      and new routine quasihydrostaticterms()
1584    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1585      New routine: mom_u_coriolis_nh()
1586    o fixed sign of non-hydrostatic metric terms in u and v equations.
1587      Depend on correct sign of gravitySign.
1588    o added work.pc* to .cvsignore in aim directories using ifc
1589    o introduced flag for controllin non-hydrostatic metric terms
1590    o removed gravitySign from PARM04
1591    o switched to g77/ifc from pgf77 in aim experiments
1592    
1593    checkpoint46l_post
1594    o made convective adjustment work with pressure coordinates:
1595     - changed the direction of k-loop in convective_adjustment.F for the
1596       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1597     - adjusted the reference pressure k-index in convective_adjustment.F
1598     - adjusted the convection condition in convect.F (in analogy to
1599       calc_ivdc.F)
1600     - convective_adjustment no longer computes anything on the halos
1601     - removed the warnings about negative salinity from find_rho.F and
1602       find_alpha.F; instead the new routine look_for_neg_salinity, called
1603       at the beginning of find_rho, find_alpha, and find_beta, does a
1604       check of the entire slice, if CPP-option
1605       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1606    checkpoint46l_pre
1607    
1608    checkpoint46k_post
1609    o fixed the verification/global_ocean.90x40x15 experiment:
1610     - new bathymetry (the world according to A., JMC, and M.)
1611     - new initial fields and forcing fields (*.bin files)
1612     - new POLY3.COEFFS (for the next release one should switch to a full
1613       equation of state: JMD95P or MDJWF)
1614     - fixed several errors and redundancies in the data file
1615     - experiment uses looped cells
1616     - added matlab directory with diagnostic scripts for plotting of output
1617    
1618    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1619     - read AIM physics parameters from a file (data.aimphys)
1620     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1621    
1622    checkpoint46j_post
1623    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1624    o move wVel computation at the end of the time step, in S/R integr_continuity
1625    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1626    o update timeave pkg for wVel diagnostic.
1627    checkpoint46j_pre
1628    
1629    checkpoint46i_post
1630    o Clean up AIM package (and keep the results unchanged):
1631      include CPP_OPTION and use IMPLICT NONE in all routines ;
1632      declare all the variables _RL ; use _d 0 for all numerical constants.
1633      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1634    
1635    checkpoint46h_post
1636    o cleaned up the use of rhoNil and rhoConst.
1637      - rhoNil should only appear in the LINEAR equation of state, everywhere
1638        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1639        and the dynamical equations are all divided by rhoConst
1640    o introduced new parameter rhoConstFresh, a reference density of fresh
1641      water, to remove the fresh water flux's dependence on rhoNil. The default
1642      value is 999.8 kg/m^3
1643    o cleanup up external_forcing.F and external_forcing_surf.F
1644      - can now be used by both OCEANIC and OCEANICP
1645    checkpoint46h_pre
1646    
1647     Added code to convert surface volume flux (fresh water) into
1648     a mass flux when using P coordinates in the ocean (OCEANICP).
1649     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1650    
1651    checkpoint46g_post
1652    o Include a new diagnostic variable phiHydLow for the ocean model
1653      - in z-coordinates, it is the bottom pressure anomaly
1654      - in p-coordinates, it is the sea surface elevation
1655      - in both cases, these variable have global drift, reflecting the mass
1656        drift in z-coordinates and the volume drift in p-coordinates
1657      - included time averaging for phiHydLow, be aware of the drift!
1658    o depth-dependent computation of Bo_surf for pressure coordinates
1659      in the ocean (buoyancyRelation='OCEANICP')
1660      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1661        Theta, Salinity, and Pressure in the parameter list. This routine is
1662        presently contained in find_rho.F. This routine does not give the
1663        correct density for 'POLY3', which would be a z-dependent reference
1664        density.
1665    o cleaned up find_rho
1666      - removed obsolete 'eqn' from the parameter list.
1667    o added two new verification experiments: gop and goz
1668      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1669    checkpoint46g_pre
1670    
1671    checkpoint46f_post
1672    o Enable tangent linear (forward mode) gradient checks:
1673      - extended active file handling to g_... files
1674      - added TANGENT_SIMULATION to theSimulationMode
1675      - extended grdchk package accordingly
1676    o added tangent linear setup in verification/carbon/code_ftl
1677    o added adjoint setup in verification/front_relax/code_ad
1678    
1679    checkpoint46e_post
1680    o Added new equation of state -> MDJWF
1681      - EOS of McDougall et al., 2002, JAOT, submitted
1682      - caveat: the equation of state is only valid for a smaller (more
1683        realistic?) range of values than JMD95P/Z and UNESCO
1684      - added masks to the calculation of pressure in store_pressure
1685      - added more check values for density in check_eos (ini_eos.F), some of
1686        the old check values are out of the range of the MDJWF-eos, so don't
1687        expect perfect matches for those
1688    checkpoint46e_pre
1689    
1690    checkpoint46d_post
1691    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1692      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1693      case of pressure coordinates. eosType='JMD95Z' in
1694      combination with buoyancyRelation='OCEANICP' now causes an error.
1695    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1696      in find_alpha/beta.
1697    checkpoint46d_pre
1698    
1699    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1700      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1701    
1702    checkpoint46c_post
1703    o Changes necessary for ocean in p-coordinates
1704     -  Added new buoyancy relation = 'OCEANICP'
1705     -  Added new parameters = gravitySign (this used to be contained inside
1706        the factor dRdZ which I added when we first switched to R coordinates).
1707     X GM/Redi is not compatible (yet)
1708     X bottom drag and no-slip need to be debugged.
1709    checkpoint46c_pre
1710    
1711    checkpoint46b_post
1712    o Added new equation of state -> JMD95Z and JMD95P
1713      - EOS of Jackett and McDougall, 1995, JAOT
1714      - moved all EOS parameters into EOS.h
1715      - new routines ini_eos.F, store_pressure.F
1716    o Added UNESCO EOS, but not recommended because it requires
1717      in-situ temperature (see JMD95)
1718    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1719      unesco.f to be used with POLY3
1720    checkpoint46b_pre
1721    
1722    checkpoint46a_post
1723    o Added (atmospheric) pressure loading
1724      - new field in FFIELDS.h, etc...
1725      - new cpp flag ATMOSPHERIC_LOADING
1726    o Changed hFacC to _hFacC in calc_phi_hyd.F
1727    o Added SHORTWAVE_HEATING to some files for consistency
1728    checkpoint46a_pre
1729    
1730    checkpoint46
1731    further merges from release1_p5
1732    o new ctrl package
1733      - adopted from ECCO environment to enable optimization
1734      - added Eliassen Palm fluxes to controls
1735    o added Eliassen Palm flux controls to gradient check package
1736    o cost package
1737      - Compatible with new ctrl package
1738      - added Eliassen Palm cost hooks
1739      - modif's of existing cost functions
1740    o Adjoint-related bug fixes in kpp:
1741      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1742      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1743    o autodiff package
1744      - flow directives:
1745        + new for S/R do_the_model_io
1746        + enhanced for S/R checkpoint
1747        + new gmredi.flow
1748      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1749        disable adcommon.h/g_common.h by default.
1750      - fixed problem for adjoint of global_max
1751    o modified verification/carbon/

1753    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1754    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1755    o incorporated hooks for sponge layer code (external_forcing.F)
1756    
1757    checkpoint45d_post
1758    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1759    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1760      (affects plume_on_slope "cg2d" output)
1761    o add new parameter deltaTfreesurf for free-surface time stepping
1762    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1763    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1764    o change phiMin in exp1 (to agree with documentation)
1765    o add new flags:
1766     - T,S forcing inside/outside Adams-Bashforth
1767     - turn off temp,salt advection and/or forcing
1768     - for each tracer, define internal flag for multiDimAdvection & A-B
1769    o monitor: change definition of KE to check conservation of Energy
1770    
1771    checkpoint45c_post
1772    o Removed f90 comments ("!")
1773    o Modified initialisations to enable exf package for MITgcm
1774      (without invoking ECCO_PACKAGE).
1775    o modifications to gradient check package (Martin Losch)
1776      - enable centered differences
1777      - modified format of standard output
1778    
1779    checkpoint45b_post
1780    o cleaned exchange calls in cg2d
1781    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1782    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1783      to configure barotropic setup (Martin Losch)
1784    o moved some initialisations within bi,bj loop in dynamics
1785      (TAF flow dependency)
1786    o in initialise_varia, moved call packages_init_variables
1787      before convective_adjustment_init
1788      (corresponding adjustment of TAF tape initialisation).
1789    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1790    
1791    checkpoint45a_post
1792    o compute Rho over the whole domain (extend iMin,jMin indices)
1793    o specific exchange for X-slice domain (case Ny=1)
1794    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1795    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1796    
1797    checkpoint44h_post = checkpoint45
1798    o Fix to restore differentiability:
1799      place at which packages_init_variables is called in
1800      initialise_varia is crucial for reverse control flow.
1801    o modifications in GMRedi to enable stable adjoint
1802      (corresponding modif's in thermodynamics, dynamics)
1803    o added missing hook for sponge layer code in external_forcing

1808      (conflict on some platforms, e.g. IBM SP3)
1809    o modified carbon verif.
1810    
1811    checkpoint44h_pre
1812    o vertical grid option: allow to put the Interface at the middle between
1813      2 cell-centers ; replace delZ in pkg/kpp by drF.
1814    o GM Advective form: Tracers are advected using the residual transport (=
1815      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1816    
1817    checkpoint44g_post
1818    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1819      results) ; ifdef missing in thermodynamics.F
1820    
1821    checkpoint44f_pre,checkpoint44f_post
1822    o added PTRACERS package
1823      This allows an arbitrary number of passive tracers to be integrated
1824      forward simultaneously with the dynamicaly model.
1825      + Implemented so far:
1826        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1827        - I/O and checkpointing
1828        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1829      + Not implemented so far:
1830        - KPP
1831        - OBCS
1832      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1833        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1834        line in data.pkg.
1835      + This package is disabled by default since it increases storage.
1836    
1837    
1838    o testscript: added -cleanup option
1839    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1840                 b) enable to filter 2D fields.
1841    
1842    checkpoint44e_pre,post
1843    o re-wrote convective adjustment to use pre-calculated weights
1844      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1845      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1846      Original calls to convect() still in place.
1847    
1848    chkpt44d_pre,post
1849    o added missing EXCLUDE_MONITOR flags
1850    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
1851      (incompatible typ in MIN/MAX expressions caused problems
1852      on IBM SP3)
1853    o in genmake added variable MAKEDEPEND
1854      plus resetting for case SunOS
1855    o added timer_stats.c routine for IBM SP3
1856    o removed variables in dynamics
1857    !!! I forgot to create tag chkpt44d_pre !!!
1858    !!! But chkpt44d_pre = chkpt44c_post    !!!
1859    
1860    o real fresh water flux implemented with non-linear free-surface.
1861    
1862    chkpt44c_pre,post
1863    o few fix (mask in shap_s2, EmPmR in external_field_load,
1864      USE_NATURAL_BCS in solve_for_P);
1865    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
1866    
1867    checkpoint44b_pre/_post
1868    o merge of relevant stuff from the ecco-branch:
1869      - genmake: removed $S64 overwrite for case SunOS
1870      - pkg/exf: update and corrections for field swapping and obcs
1871      - pkg/ecco: parameter lists for the_model_main, the_main_loop
1872                  harmonized between ECCO and MITgcm
1873      - pkg/autodiff: added flow directives for obcs, mdsio_gl_slice
1874                      updated checkpointing_lev... lists for obcs
1875      - model/src: minor changes in forward_step, plot_field
1876                   added directive for divided adjoint in the_main_loop
1877      - pkg/mdsio: added mdsio_gl_slice
1878

1893    o added test of H&S94 with free surface on cube
1894    o some final mods for gradient check, adjoint,...
1895    
1896    checkpoint42
1897      Fixed AD-related problems:
1898    o Store directives up-to-date with re-arranged Adams-Bashforth
1899      (mainly thermodynamics.F)
1900    o New store directives for multi-dim. advection schemes
1901      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
1902      * new common block and key passkey
1903      (mainly gad_advection.F)
1904    o Modified store directives for split of dynamics/thermodynamics
1905      for the case ALLOW_KPP
1906    o Cleaned argument list for timestep_tracer.F
1907    
1908    checkpoint41
1909    o re-formatted/added comments in prologues of key subroutines
1910      to work with protex
1911    
1912    checkpoint40
1913    o moved calc_gs, calc_gt and calc_tr1 back to model/src
1914    o added FLT (floats) package from Arne along with demo. experiment
1915    o re-arranged Adams-Bashforth scheme for tracers to allow easier
1916      implementation of forward-in-time forcing terms
1917    o more mods for non-linear free-surface including new variable
1918    o modified multi-dim method to work on cube
1919    o bug fix in KPP (from DM)
1920    
1921    checkpoint40pre9

1927    o changes to commenting of arguments for TAF/TAMC
1928    o added/updated many matlab scripts
1929    o added multi-dimensional advection method for tracers
1930      
1931    checkpoint40pre8
1932    o new package rw/
1933      Added method for dumping intermediate local arrays:
1934      mdsio_writetile - same as mdsio_writefield except works from inside
1935                        bi,bj loop
1936      mdsio_writelocal - same as mdsio_writetile except works for local
1937                         arrays
1938      write_local_r? - higher-level wrapper for mdsio_writelocal
1939      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1940      Example given at end of mom_vecinv.F that dumps some local arrays.
1941    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1942      control flux-form versus vector invariant code.
1943      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1944      or genmake -DISABLE ...
1945    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1946      (additional storing is now needed for case vecinv;
1947      currently nothing implemented to switch this storing off
1948      in case fluxform is used since no CPP flag available).
1949    
1950    checkpoint40pre7
1951    o bug fix in dynamics.F
1952      calc_viscosity called before k=1,Nr loop.
1953    o added some #ifdef's ALLOW_PASSIVE_TRACER
1954    o cleaned initialisations in ctrl_map_ini
1955      related to TAF
1956    
1957    checkpoint40pre6
1958    o split dynamics into thermodynamics & dynamics
1959    o corresponding split of calc_diffusivity into
1960      calc_diffusivity, calc_viscosity
1961      (kpp_calc_diff, kpp_calc_visc).
1962    o Added diffkr, kapgm to control variables
1963    o bug fix in gmredi_slope_limit for ldd97
1964    
1965    checkpoint40pre5
1966    o proper initialization of Adams-Bashforth time stepping
1967      + uses forward step for very first step of model (iter=0)
1968    o re-generated *all* output since almost all output is modified by this
1969      change (sorry but we've been putting this one off for about 2 years)
1970      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1971        *not* regenerated since they are already out of date and I don't
1972        want to create the impression that they are suddenly working.
1973    o removed KAP stuff for DEC's
1974    o modified/added many .cvsignore files in */code and */input
1975    o added new expt "solid-body.cs-32x32x1"
1976      + this uses an alternative form of ini_curvilinear_grid.F which
1977        is not necessarily any better than the current one...
1978    
1979    checkpoint40pre4
1980    o added re-initialisations of utrans,vtrans,rtrans in
1981      calc_common_factors which are crucial for TAF.

2005     o Included following packages:
2006       cal: calendar
2007       exf: external forcing
2008       ecco: essential routines to control use of cal, exf

2019    
2020    checkpoint37
2021     o mdsio.F routine split and packaged in pkg/mdsio
2022       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
2023        used unless genmake -disable=mdsio)
2024     o allow a more precise surface-geopotential gradient for the atmosphere
2025       taking into account the change in space of Alpha (=1/rho) at the surface.
2026     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
2027       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
2028     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
2029       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
2030       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
2031     o Time-Average diagnostics defined as a pseudo package "timeave".
2032     o pickup files : old pickup (before c35) did not work with new code (c35
2033       and after) unless activating 2 commented lines in initialise-varia.
2034     o Non-Hydrostatic pickup file Pb fixed.
2035     o bug with Rigid-lid version (since c35) fixed.  
2036    
2037    checkpoint36

2039     o recover Time-Average diagnostics
2040     o fix Pb in checkpoint (PR#19)
2041     o AIM become a standard package ; clean unused CPP_kees
2042    
2043    checkpoint35
2044     o subtantial rewrite of dynamics.f
2045     o allows staggered time-stepping
2046     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
2047     o added bottom drag (linear + quadratic)
2048    
2049    checkpoint34
2050     o Modified exchange routines for correct reverse simulation.
2051     o Added verification output to comply with bug fix in impldiff.F
2052       as of c33 (exp2, natl_box).
2053     o Corrected store directives in dynamics.F
2054     o Corrected array boundaries in impldiff.F
2055     o Corrected array dimensions in gmredi.

2059    
2060    checkpoint33
2061     o Fixed bug in lower BC in impldiff.F
2062     o Fixed confusion about units of forcing arrays in FFIELDS.h
2063       namely Fu,Fv,Qnet,Qsw,EmPmR:
2064       - Removed verification/natl_box/code/external_fields_scale.F
2065         (did not differ from that in model/src)
2066       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
2067         (see FFIELDS.h for description)
2068       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
2069         kpp_calc.F and kpp_transport_t.F
2070       - Removed model/src/external_fields_scale.F and calls to it
2071       - verification/natl_box uses flux data with "atmospheric" sign so
2072         a special version of external_fields_load.F is used to
2073         change the data as it's read in. This way, the arrays
2074         have the right units and signs at all times tha a user could
2075         possibly use them.
2076     o Corrected genmake to delete a temporary file during configuration
2077    
2078    checkpoint32
2079     o Scaling of forcing fields moved from external_forcing.F to

2082       extra subroutine.
2083     o impldiff.F changed to avoid storing by TAMC of huge intermediate
2084       fields.

2091       -> new routines packages_...F
2092       -> changes in initialise_fixed.F, initialise_varia.F
2093       -> enables initialisation interface for ECCO package
2094     o Rescaling of external forcing fields immediately after read
2095       (removed from external_forcing.F)
2096       -> new: surface_fields_scale.F
2097       -> affects ini_foorcing.F, external_fields_load.F
2098     o Computation of surface tendencies before tendency updates.
2099       -> new: external_forcing_surf.F
2100     o Change of variable names useGMRedi, useKPP, useECCO
2101     o Further changes in dynamics.F, impldiff.F for TAMC
2102     o Tested for experiments 0, 2, 4.
2103       - not yet tested for GMRedi.
2104       - not yet tested for KPP.
2105

2116     o packaged KPP and GM/Redi
2117    
2118    checkpoint28
2119     o Corrected initialization of hFacMin for difference vertical coordinates
2120     o Modified calculation of partial cell thickness to more robust algorithm
2121     o config_summary.F: replaced write_1D_... by write_0D_...
2122       read_write.F: added subroutines write_0D_...
2123     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
2124       included some initialisations required for TAMC.
2125     o routine calc_isoslopes: modified sqrt computation to make it
2126       differentiable for zero argument.
2127     o routines dynamics, impldiff:
2128       included store directives and tape key computations required for TAMC.
2129     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
