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

837    
838    checkpoint52a_pre
839    o some bug fixes for #undef REAL4_IS_SLOW
840    
841    checkpoint52 = ecco_c52_e35
842    o after testing adjoints of checkpoint51u_post
843    
844    checkpoint51u_post
845    o this is the post-merge tag of the ecco-branch
846      (needs another clean checkout and re-testing)
847    o various natl_box_adjoint configs and results
848      but no input fields
849    o obcs adjoint not yet merged!
850    o adding ECCO global 1x1 and 2x2 degree configs
851    o updated/extended some store directives for seaice
852    o pkg/ecco now containes ecco-specific part of cost function
853    o top level routines the_main_loop, forward_step
854      supersede those in model/src/
855      previous input data.cost now in data.ecco
856      (new namelist ecco_cost_nml)
857    o in ctrl/ cleaned some cross-dependencies and updated CPP options
858    
859    checkpoint51t_post
860    o this is the pre-merge tag of the ecco-branch
861    
862    checkpoint51s_post
863    o cleanup: removed various obsolete #define-s
864    o pkg/grdchk
865      - renamed 'ph-grd 3' to 'grad-res'
866      - merged from ecco-branch
867        (remaining bug fixes for obcs gradient checks)
868      - additional high-precision output for testreport
869        (grep for 'precision_grdchk_result')
870    
871    checkpoint51r_post
872    o cleaned up or removed CPP_OPTIONS.h files
873    o updated results for some of the tests to reflect the new
874      optfiles (-ieee: -O0 instead of -O3)
875    
876    checkpoint51q_post
877    o cd_code:
878      - moved cd_scheme.F -> cd_code_scheme.F
879      - separate read_checkpoint from cd_code_ini_vars.F
880      - separated cd_code part from write_checkpoint
881      - updated AD_SOURCE, generated .flow
882      - added CD_CODE_VARS.h to the_main_loop
883      - Moving cd_code specific store dir.s to pkg/cd_code
884    o ctrl package totally restructured
885      - pack/unpack now optional and decoupled from
886        xx_/adxx_ I/O
887      - ctrl_pack/unpack cleaned
888        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
889      - confined inclusion of AD_CONFIG.h to where necessary.
890    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
891    
892    checkpoint51p_post
893    o create initial cd_code package
894      - WARNING: the initialization of fields within packages
895        is broken because INI_FIELDS (where READ_CHECKPOINT is
896        called) is called *before* PACKAGES_INIT_VARIABLES.
897        This seems to be backwards since
898        1) its important to initially zero the entire field including
899           the "halo" region
900        2) zeroing needs to be done *before* reading pickup info
901           and the pickup call might or might not happen in any
902           particular run
903      - this needs an overhaul for R2
904    o cleanup verification/*/code/GMREDI_OPTIONS.h
905    o cleanup testreport
906    
907    checkpoint51o_post

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

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

1113    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1114    o AIM: use true log-P extrapolation for near surface temp (= as in
1115        F.Molteni paper) ; update aim.5l_cs output.
1116    o New variable in PARM03 for more flexible pickups
1117    o somewhat cleaned package initialisation sequence for
1118      ctrl/ cost/ ecco/ in packages_... routines
1119    
1120    checkpoint50g_post

1122      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1123      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1124        made the default because of faster convergence than ADI
1125    
1126    checkpoint50f_post
1127    o exf totally restructured

1182    
1183    checkpoint50b_pre
1184    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1185    o corrected CPP option mismatch in exf_Bulk... functions for case
1186      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1187    
1188    checkpoint50a_post
1189    o Bug fix for merging between c50 and KPP.
1190      ikey was passed from thermodynamics to kpp_calc via
1191      common block rather than being recomputed in kpp_calc,
1192      in contradiction with new key itdkey.
1193      New key ikppkey created, and tamc.h headers updated.
1194    
1195    checkpoint50
1196    - 2nd step of merge with ecco-branch:
1197      merge changes in ecco-branch back into main trunk
1198    - bug fix in find_alpha
1199    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1200    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1201    - merged some sliced AD support routines
1202    
1203    checkpoint49
1204    merged from ecco-branch:
1205    o exf:
1206      - Enable initialisation of forcing fields to constant
1207        (runtime) values.
1208      - in exf_getffields.F
1209        Reduce i-/j-loop to interior domain, discarding overlaps.
1210        That also fixes wrong TAF-key computations for key_1, key_2
1211        with bulf formulae.
1212      - exf_init.F modify #ifdef for exf_init_evap
1213      - exf_getffieldrec.F, ctrl_getrec.F
1214        The following INT-usages are not safe:
1215          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1216          fldcount = int(fldsecs/fldperiod) + 1
1217        and were modified.
1218    o autodiff: checkpoint_lev...
1219      - updated storing for bulk formulae (some arrays were missing)
1220      - added state for seaice package
1221      - synchronized with main branch
1222    o DIVA:
1223      Modif.s in
1224      - the_main_loop.F
1225      - the_model_main.F
1226      and added cost_final_restore.F cost_final_store.F
1227      o With these changes, it is possible to fully separate
1228        the first forward run to compute the cost function (mdthe_main_loop)
1229        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1230        into separate model executions.
1231        This enables better tuning of DIVA to given queue sizes.
1232      o Loss of cost function value in consecutive DIVA runs is
1233        fixed by storing to 'costfinal' file.
1234      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1235        beginning/end of adjoint integration is accounted for.
1236      The current changes apply to TAF-1.4.26.
1237      TAF has one remaining bug, requiring one manual change
1238      (see MITgcm manual).
1239    o cal: synchronized between MAIN and ecco-branch
1240    
1241    checkpoint48i_post
1242    o Changes to restore differentiability of code w.r.t. previous tag
1243      (mostly adding new routines to make list and replacing
1244      pressure by totPhiHyd).
1245    o Updated and merged grdchk package
1246      - has both ADM and TLM checks
1247      - works for single- and multi-proc.
1248      - output cleaned
1249      - worked successfully for parallel DIVA
1250    o genmake:
1251      - Adding -platform=SP4
1252      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1253    o Modif. for DIVA:
1254      ctrl_unpack should not be called in intermediate DIVA interval.
1255      (similar thing would apply for active files such as
1256      tbar, sbar, psbar, which should not be reinitialised;
1257      only relevant for ecco-branch)
1258    
1259    checkpoint48h_post
1260    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1261    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1262    o Added SEAICE_initialHEFF to pkg/seaice
1263    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1264    
1265    checkpoint48g_post
1266    --- EOS:
1267    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1268      store total Potential in totPhyHyd for diagnostics & EOS.
1269    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1270    --- Pressure/geopotential gradient:
1271    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1272    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1273      ( changes results of global_ocean_pressure )
1274    o NLFS + z-coord.: add eta*Rho' contribution.
1275    o accurate phiHyd when using interface-W at the middle between 2 centers
1276     ( changes results of ideal_2D_oce )
1277    o includes r* 2nd term in potential gradient.
1278    
1279    checkpoint48f_post
1280    Merging from release1_p12:
1281    o Modifications for using pkg/exf with pkg/seaice
1282      - improved description of the various forcing configurations
1283      - added basic radiation bulk formulae to pkg/exf
1284      - units/sign fix for evap computation in exf_getffields.F
1285      - updated verification/global_with_exf/results/output.txt
1286    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1287      (SBO) core products, including oceanic mass, center-of-mass,
1288      angular, and bottom pressure (see pkg/sbo/README.sbo).
1289    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1290      to avoid negative values in shallow regions.
1291      - updated verification/natl_box/results/output.txt
1292      - updated verification/lab_sea/results/output.txt
1293    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1294    o Added useSingleCpuIO option (see PARAMS.h).
1295    o Updated useSingleCpuIO option in mdsio_writefield.F to
1296      work with multi-field files, e.g., for single-file pickup.
1297    o pkg/seaice:
1298      - bug fix in growth.F: QNET for no shortwave case
1299      - added HeffFile for specifying initial sea-ice thickness
1300      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1301    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1302      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1303    o pkg/seaice:
1304      - adjoint-friendly modifications
1305      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1306    
1307    checkpoint48e_post
1308    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1309    o dynamics: change definition of computational domain & adapt mom_fluxform
1310      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1311    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1312        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1313        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1314        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1315        inverted_barometer solid-body.cs-32x32x1
1316      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1317    
1318    checkpoint48d_post
1319    o in preparation for r*:
1320     a) use pre-computed gradient of hydrostatic potential:
1321        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1322     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1323        => affects results of glob_oce_pressure (different truncation error)  
1324      update output.txt of ideal_2D_oce & global_ocean_pressure
1325    
1326    checkpoint48d_pre
1327    o in preparation for r*:
1328      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1329      pass the 2 comp. of the grad. as arguments to momentum S/R.
1330      but for the moment, only used if it does not change the results.
1331    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1332    
1333    checkpoint48c_post
1334    Modifications in treatment of initial flux forcing controls
1335    to avoid extra storing of flux fields.
1336    
1337    checkpoint48c_pre
1338    o Added tidal_basin_2d experiment (currently 1D!)
1339    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1340    
1341    checkpoint48b_post
1342    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1343     (modification to pressure gradient not yet implemented)
1344    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1345      (for U & V) that are used for vertical advection of momentum.
1346    
1347    checkpoint48a_post
1348    o In preparation for r*, use temp. array to compute vertical transport
1349       in flux-form momentum pkg. => change results of few test-exp.
1350      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1351                        lab_sea, natl_box & plume_on_slope
1352    
1353    checkpoint48
1354    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1355    
1356    checkpoint47j_post
1357    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1358    o moved adexch from forward_step to addummy_in_stepping
1359    o added exch in ctrl_map_...
1360    o aveFreq.=0. at end of cost_final to avoid overwrite in
1361      reverse checkpointing loop
1362    o Yet more changes in gmredi:
1363      * adgmredi_calc_tensor
1364        avoiding all recomputation of gmredi_slope_limit
1365      * adgmredi_x/y/rtransport
1366        added flag for excessive storing to avoid recomp. of
1367        u/v/rtans, dTdx/y/z
1368        -> this is not really necessary and very memory-consuming
1369      * adgmredi_slope_psi:
1370        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1371      * gmredi_slope_limit
1372        re-activated full calculation of taperfct for case 'ac02'
1373    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1374    
1375    checkpoint47i_post
1376    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1377    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1378      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1379    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1380    o gmredi: fix few bugs.
1381    
1382    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1383    This will be a good checkpoint to plug into the ecco-branch.
1384    o few modif.'s to get latest version adjointed
1385      (mainly kick out code in ini_linear_phisurf)
1386    o modif's to run adjoint with exactConserv
1387    o case GM_BOLUS_ADVEC should be cleaned
1388      S/R gmredi_slope_psi should be cleaned
1389    o verification/carbon now has exactConserv=.TRUE.
1390    
1391    checkpoint47g_post
1392    o time-average AIM output: becomes independent from statvars time-average
1393      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1394    o After TAF bug fix:
1395      Tested adjoint of gmredi package.
1396      Tests were done with checkpoint47 rather than with latest
1397      checkpoint47f_post since the latter is broken for the adjoint
1398      verification/carbon/ contains both ADM and TLM gradient checks.
1399    Here they are, before they get changed/lost/stolen.
1400    Mostly modif.'s to fix numerical sensitivities.
1401    Gradient checks OK for
1402    - GM_taper_scheme:
1403      * clipping
1404      * ac02
1405      * linear
1406      * glw91
1407      * dm95
1408      * ldd97
1409    - GMREDI_OPTIONS:
1410      * GM_VISBECK_VARIABLE_K
1411      * GM_NON_UNITY_DIAGONAL
1412      * GM_EXTRA_DIAGONAL
1413      * GM_BOLUS_ADVEC
1414    in conjunction with data.gmredi parameters to be checked in
1415    in a few minutes under verification/carbon/code/
1416    
1417    checkpoint47f_post
1418    Merging from release1_p10:
1419    o modifications for using pkg/exf with pkg/seaice
1420      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1421        and SEAICE_EXTERNAL_FLUXES
1422      - pkg/exf CPP options EXF_READ_EVAP and
1423        EXF_NO_BULK_COMPUTATIONS
1424      - usage examples are Experiments 8 and 9 in
1425        verification/lab_sea/README
1426      - verification/lab_sea default experiment now uses
1427        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1428    
1429    checkpoint47e_post
1430    o created a tag prior to creating a branch
1431    
1432    checkpoint47d_post
1433    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1434      at the bottom boundary had an erroneous half slip boundary condition
1435    o added bottom drag and no slip boundary condition capabilities to
1436      oceanic pressure coordinates code
1437    o added new verification experiment global_ocean_pressure, this experiment is
1438      also described in the tutorial section of the manual
1439    checkpoint47d_pre
1440    
1441    checkpoint47c_post
1442    o Added a verification experiment for a global cubed-sphere ocean run
1443      -  verification/global_ocean.cubed32x32x30
1444      -  uses pkg/therm_seaice and pkg/bulk_forcing
1445    
1446    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1447    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1448      when using P-coordinate; only implemented for atmospheric config.
1449    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1450      NOTES: requires option NONLIN_FRSURF to be "#define".
1451    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1452    
1453    checkpoint47b_post
1454    Merging from release1_p9:
1455    o pkg/seaice
1456      - removed GOTO's and added taf directives
1457      - double precision constants to reduce the g77 (Linux)
1458        to F77 (SGI) differences reported in release1_p8
1459    o tools/genmake
1460      - added SGI options
1461    o verification/testscript
1462      - updated to that of checkpoint47a_post
1463    o verification/global_ocean.90x40x15/input/eedata
1464      - modified for SGI f77 compatibility
1465    o verification/lab_sea
1466      - added description of sea-ice model
1467      - added missing matlab routines
1468      - added test of thermodynamics parallelization
1469    
1470    checkpoint47a_post
1471    o new pkg: aim_v23
1472     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1473       for now, keep the same surface forcing as before.
1474     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1475     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1476     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1477    o add diagnostic of surface correction term in monitor output
1478    
1479    o bulk_force and therm_seaice
1480    - Two packages:  bulk_force (Bulk forcing)
1481      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1482    - Earlier integration from Stephaine Dutkiewicz
1483      and Patrick Heimbach.
1484    - Two ifdef statements for compile time,
1485       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1486    
1487    checkpoint47
1488    differentiable version of checkpoint46n_post
1489    o bug fix in quasihydrostaticterms
1490    o * "clean" adjoint code (in terms of extensive recomputations)
1491        can now be obtained for all GMREDI options (i.e. for
1492        - GM_VISBECK_VARIABLE_K
1493        - GM_NON_UNITY_DIAGONAL
1494        - GM_EXTRA_DIAGONAL
1495        - GM_BOLUS_ADVEC )
1496      * However, wrong gradient check problem remains unsolved.
1497      * New CPP options have been introduced for different
1498        tapering schemes
1499    o external_fields_load now part of differentiation list
1500    o pressure needs multiple storing;
1501      would be nice to have store_pressure at beginning or
1502      end of forward_step, e.g. by having phiHyd global (5-dim.)
1503      (NB: pressure is needed for certain cases in find_rho,
1504      which is also invoked through convective_adjustment).
1505    o recomputations in find_rho for cases
1506     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1507    o #define ATMOSPHERIC_LOADING should be differentiable
1508    o ini_forcing shifted to begining of initialise_varia
1509    o Incorporating QNVS line search routines into MITgcm
1510      (this is separate code, and therefore not under pkg)
1511      lsopt/, optim/
1512    o Updated verification/carbon/
1513      - #define GM_VISBECK_VARIABLE_K
1514      - GM_taper_scheme    = 'ldd97'    
1515    
1516    checkpoint46n_post
1517    Merging from release1_p8:
1518    o verification/natl_box:
1519      updating new external_fields_load routine
1520    o New package: pkg/seaice
1521      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1522      The sea-ice code is based on Hibler (1979-1980).
1523      Two sea-ice dynamic solvers, ADI and LSR, are included.
1524      In addition to computing prognostic sea-ice variables and diagnosing
1525      the forcing/external data fields that drive the ocean model,
1526      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1527      The implied surface heat flux is then stored in variable
1528      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1529      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1530      non-local transport term.  Because this call precedes model
1531      thermodynamics, temperature under sea-ice may not be "exactly" at
1532      the freezing point by the time theta is dumped or time-averaged.
1533      N.B.: fairly large differences in accuracy occur across
1534            different platforms/compilers; comparison between
1535            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1536            generated output gives:
1537       T           S           U           V
1538      C D M    c        m  s        m  s        m  s        m  s
1539      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
1540      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d
1541      g d e n  d  n  x  n  .  n  x  n  .  n  x  n  .  n  x  n  .
1542    
1543      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1544    o GAD:
1545      - generated new common blocks to account for call of
1546        same gad routines with differing traceridentities
1547        (needed to modify tracerIdentity indices in GAD.h)
1548      - generated separate common blocks for case useCubedSphereExchange
1549        (Department of Futurology)
1550      - parameter lists to gmredi_?transport: added tracerIdentity
1551      - added new key indices to tamc.h
1552    o external_fields_load:
1553      - added this routine to TAF list
1554      - needed to make some common blocks global and additional storing
1555        along the same lines as exf package (checkpoint_lev?_directives.h)
1556    o exf:
1557      updated external forcing package
1558      - bug fixes carried over from ecco-branch
1559        (missing OBCS_OPTIONS.h in two routines)
1560      - enable easy to use "no forcing".
1561      - added exf I/O for atmospheric loading
1562      - added exf I/O for runoff data
1563      - transfered scaling between exf <-> MITgcm to exf namelist
1564    o Adding new verification experiment global_with_exf.
1565      This verification experiment is almost identical to the
1566      global_ocean.90x40x15 experiment, except that it uses
1567      the exf (and cal) package instead of the
