5      ==============================      ==============================
6    
7    o add diagnostics for (almost) each term of the momentum Eq.
8    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
9    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
10    o remove MINIMAL_TAVE_OUTPUT option ;
11      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
12    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
13      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
14    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
15    o add time-dependent SST, SSS control
16    o cost terms in ecco/ modularized (new cost_generic.F)
17    o cost_averages routines are modularized (new cost_averagesgeneric.F)
18    o new infrastructure for seaice model vs. obs misfits in seaice/
19      * driver from the_main_loop.F is seaice_cost_driver.F
20      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
21      * gradient check in Exp. 6a of natl_box_adjoint/
22    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
23      (see README file)
24    
25    checkpoint57q_post
26    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
27    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
28      - bug was reported by Jean-Michel and Ian Fenty
29    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
30      update exp. cpl_aim+ocn output.
31    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
32      Needed for high-res. runs with large global files
33      to be able to limit tapelev size
34    o Changed some tests for adjoint:
35      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
36      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
37      * global_ocean.90x40x15/ back to default 3-level checkpointing
38    o Modifications to enable scripted COMMON to MODULE conversion
39      * verification/OpenAD/code/ has necessary scripts and description;
40      * converts, compiles and runs successfully;
41    
42    checkpoint57p_post
43    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
44    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
45      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
46    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
47    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
48      (was already the case for dissipation with mom_vecinv,
49       and also the case for grad.PhiHyd when staggered-timeStep)
50      This will allow to put dissipation out-off the AB time-stepping.
51     Unfortunately, affects truncation error. Update output of exp. that "fails"
52      (cg2d matching number) and leave the others for later: front_relax(10),
53      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
54      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
55    
56    checkpoint57o_post
57    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
58      (2) its ready to be documented during the 20050801 DocFest
59    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
60      for ideal_2D_oce and lab_sea on linux_ia32_g77
61    o set to #undef CTRL_SET_OLD_MAXCVARS_30
62      in global1x1_tot/code_seaice_adj to access indices 32, 33
63      (worth another tag)
64    
65    checkpoint57n_post
66    o adding precip control xx_precip 32
67    o adding swflux control xx_swflux 33
68    o Replacing 10 forcing penalty cost routines by 1 generic.
69    o Implementing partitioning in time-mean and variable adjustment
70      for atmos. state.
71    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
72    o in natl_box_adjoint:
73      * updated exp 1 to 10
74        (but does not have time-mean vs. variable split results yet)
75    o updated global1x1/*_seaice_adj/
76      to incorporate latest changes
77    o enable useSingleCpuIO for mdsio vector routines
78      (applies in particular to tapelev I/O)
79    o removed inefficient K-loop in all active_file*control*.F
80    
81    checkpoint57m_post
82    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
83      and advect_cs (use EXCH-2 and standard cs-32 grid files).
84    o pkg/exch2: filling of face-corner halo regions is optional
85      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
86    
87    checkpoint57l_post
88     tag before updating tutorials (pre-release-2)
89    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
90       for output and interpolation of input fields onto model grid)
91    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
92       Affects results of exp. rotating_tank ; update output.txt.
93    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
94          and taking the square quantity and/or using a fraction-weight field.
95    o fix aim_diagnostics_init.F mate numbers.
96    o add mnc output capability to diagnostics/diagstat and update
97      our cvsignore files for the ACSII output generated
98    
99    checkpoint57k_post
100    o lab_sea now uses diagnostics package and provides a suite of
101      new EXF diagnostics output.
102    
103    checkpoint57j_post
104    o exf
105      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
106        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
107        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
108      * extended diagnostics output
109        - now includes all EXF variables
110        - hs, hl moved to common block
111        - separate S/R for diagnostics, called after ctrl vector is added
112        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
113        - EXFqnet contains true Qnet (i.e. includes qsw)
114      * updated verif. lab_sea, global_with_exf
115      * Rearranging hflux (exf_mapfields -> exf_getforcing)
116        to ensure that diagnostics sees a true EXFqnet
117    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
118    o diagnostics pkg: change pointers so that 1 diagnostic can be used
119      several times with different frequencies.
120    o mnc-ify the thsice package as requested by Daniel Enderton
121      - the monitor--MNC output needs work
122      - many attributes need to be added (most are currently blank)
123    o mnc-ify theaim_v23 package as requested by Daniel Enderton
124      - many attributes need to be added (most are currently blank)
125    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
126    o add Sadourny like discretization to the 4th.O vorticity advection scheme
127    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
128      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
129         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
130    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
131     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
132    
133    checkpoint57i_post
134    o Diagnostics package was changed: diagnostic allocation is now deactivated
135      by setting an empty file name in the namelist (used to be by setting 0 frequency)
136    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
137      add 1rst Order upwind vertical Shear.
138    o add a quick fix for A/B checkpointing in OFFLINE mode
139    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
140      end-run around the C/Fortran linking horror in eesup/src/timers.F
141    o added pkg/runclock: allows user to terminate run based on wall clock
142    o added non-hydrostatic scaling parameter: nh_am2
143    o pkg/my82: futile attempt to make results compiler-independent by adding
144      some "_d 0", etc. no effect.
145    o for mnc output, fill the 'T' coordinate var with myTime and create a
146      separate 'iter' variable for iteration count
147    o pkg/diagnostics:
148      add new capability: output of Global/Regional & per-level statistics ;
149      tested against monitor output (including land & thSIce) on various exp.
150    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
151    
152    checkpoint57h_done
153      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
154      data.diagnostics, data.gchem, data.ptracers) is done.
155    
156    o pkg/diagnostics: prepare for Global/Regional statistics.
157      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
158    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
159      and rename it: DIFFERENT_MULTIPLE
160    
161    checkpoint57h_post
162    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
163    o pkg/diagnostics: change output frequency, now in seconds (instead
164      of Nb of iterations). This requires to change data.diagnostics.
165    checkpoint57h_pre
166    
167    o in mnc, let the user create the output dir if both mnc_outdir_date
168      and mnc_outdir_num are false
169    o add fflags() to pkg/diagnostics which allows one to specify, on a
170      per-file basis, the file precision [default behavior is unchanged]
171    o added diagnostics to pkg/kpp, including computation of mixed layer
172      depth based on a temperature/density criterion
173    o updated verification/natl_box to test the new pkg/kpp diagnostics
174    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
175    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
176    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
177      not mnc -- this mistake was found by JMC and is now corrected
178    
179    checkpoint57g_post
180    o add Adams-Bashforth 3rd Order time stepping:
181      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
182      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
183    checkpoint57g_pre
184    
185    o make lambda[Theta,Salt]ClimRelax spatially varying
186      (default remains spatially uniform constant based on tau)
187    o added new control variables
188      * init. uVel, vVel, etanN
189      * lambda[Theta,Salt]ClimRelax
190    o separate masks used for ctrl_pack/unpack 'from write_grid' output
191      (suggested by G. Forget)
192    
193    checkpoint57f_post
194    o add parameter "baseTime" = model base time = time at iteration zero
195      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
196      account for baseTime shift
197    o move Coriolis arrays from PARAMS.h to GRID.h
198    checkpoint57f_pre
199    
200    o mnc-ifying the seaice package
201    o introduced an alternative length scale calculation for use in the limiting
202      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
203    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
204    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
205      as well as grad(vort3).  Made it compatible with both approximate form
206      for the cubed sphere and full form of these gradients.  Added flag
207      useFullLeith to select between approximate and full form.  
208    o add "d0" in getcon.F to reduce differences between compilers/platforms
209      update output.txt of exp. fizhi-gridalt-hs
210    o change port_rand funtion to allow to set the seed.
211    o fix obscure MNC bug involving conversion between reals and integers
212      - it caused no problems with certain (eg. gcc, ifc) compilers but the
213        new version is now more standards-compliant
214    o adjoint-related modifications
215      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
216      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
217      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
218    
219    checkpoint57e_post
220    o Adding eddy stress controls a la Ferreira et al.
221    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
222    
223    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
224      update output.txt of exp. fizhi-gridalt-hs
225    o add more "Z" dimensions and associated coordinate vars to MNC
226    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
227    o parameter calendarDumps: when set, approximate months (30-31 days) and years
228      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
229      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
230      months and years.  Requires pkg/cal.
231    o diagnostics: add pickup functionality
232      - off by default for backwards compatibility
233      - current version only uses MDSIO -- MNC will be added
234    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
235    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
236    
237    checkpoint57d_post
238    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
239    o modify verification/ideal_2D_oce so that it tests the creation of mnc
240      output from the diagnostics package
241    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
242    o make genmake2 more portable by using ".$FS" instead of ".f" for more
243      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
244    o add coordinate variables to the MNC output from the diagnostics package
245    o change MNC-flags default value: true when useMNC=TRUE
246    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
247      the ability (off by default) to read the grid information using MNC
248    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
249    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
250    o do snap-shot diagnostics at the middle of the time-interval (instead of
251      at the end).
252    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
253      new test for AIM with thSIce + slab-ocean
254    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
255    o move state variable diagnostics to the beginning of the time step ;
256      (note: still needs some work specially for snap-shot diagnostics)
257      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
258    
259    checkpoint57c_post
260    o Change testing option (-ieee) to get closer agreement between g77 & ifort
261    o generate new output.txt files on faulks with g77 & the new -ieee option
262    checkpoint57c_pre
263    
264    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
265      update output.txt of exp. global_ocean.90x40x15
266    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
267      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
268    o add saltFlux(+File) forcing capability with periodicExternalForcing
269    o allow to use pkg diagnostics for GM-Redi & ThSIce output
270    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
271    o improvements for the MNC output from DIAGNOSTICS:
272      - correct handling of the unlimitied dimension
273      - all dims now have associated coordinate variables
274      - variables located at U, V, and Corner ("Z") points are now written
275        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
276        *all* data points are output
277    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
278    o added pkg/seaice/seaice_monitor.F
279    o mdsio_readfield.F can now read files visible only to master MPI process.
280    o pkg/seaice: some test code for ice-modified ocean stress
281    o exf_getffields interpolation defaults to bilinear for all scalar forcing
282      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
283      spurious negative numbers for precipitation and humidity.  Will cause
284      some small numerical differences for integrations using pkg/exf/exf_interp.F.
285    o pkg/ctrl/
286      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
287        May be enabled via doPackDiag
288      *  introduce z-scaling of
289         + gradient (doZscalePack) and
290         + control (doZscaleUnpack)
291    o pkg/mdsio/
292      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
293      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
294    
295    checkpoint57b_post
296    o simplify options in diagnostics_fill arguments (remove weird combinations)
297    o fix MNC coordinate variables so that they now contain per-face index
298      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
299      general, EXCH2 grids are only aligned to a "local" coordinate system
300    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
301    o Implement instantaneous output within pkg diagnostics:
302      setting a negative frequency in data.diagnostics produces
303     "snap-shot" output (as opposed to time-average if freq > 0)
304    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
305      NOTE: change ptracer diagnostics name: use 2 characters to work with
306            more than 9 tracers. Add also diagnostics of advect & diffus flux.
307    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
308      becomes the coordinate variable for the 'T' dimension
309    o add CF-style coordinate variables to MNC
310      - just a first cut:  numbers are meaningless on the cubesphere and
311        missing along the T axis but otherwise it works!
312    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
313    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
314    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
315      this is based directly on what the model compute, so that the content of
316      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
317    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
318    o clean up build options files for SunOS, in particular
319      - remove -traditional from xmakedepend
320      - change -xarch=v9 to -xarch=native for f77
321      - restore use of make (not gmake)
322      - add CC=gcc if using g77
323    o changes per discussion of AM, JMC, & EH3 today:
324      - move redundant "grid" variables out of "state" -- in preparation of
325        creating proper CF-style coordinate variables and in recognition
326        that any/all grid variables can be easily copied (eg. w/NCO) from
327        the grid files into any of the other NetCDF files
328      - *always* output grid variables with MDSIO (this will eventually be
329        changed)
330      - output MNC grid file if useMNC is true
331    o every instance of _END_MASTER() has been found and replaced with
332      _END_MASTER( myThid ) in order to satisfy certain picky Sun
333      preprocessors
334    o re-arrange diagnostics pkg initialisation:
335     - allow each package to extend the available diagnostics list
336     - add some checking and fix small problems (multi-threaded, ...)
337     - new S/R diagnostics_fill (replace fill_diagnostics):
338       look through the short list of active diag. (instead of the long list)
339       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
340    
341    checkpoint57a_post
342    o this set of changes restores TAMC compatibility
343      tested for global_ocean.90x40x15 adjoint on trough
344      (what a pain)
345    
346    checkpoint57a_pre
347    o some modifs in tools/build_options for sunos
348    o call ctrl_pack for ctrl at end for optimcycle=0
349    
350    checkpoint57
351    o add horizontal bi-harmonic viscosity for vertical velocity
352      - new parameter viscA4W (defaults to viscA4)
353      - affects only non-hydrostatic code
354      - to be done: no-slip lateral boundary conditions
355    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
356    o implement Implicit Vertical advection for pTracers
357    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
358      (implemented also for implicit vertical diffusion & advection)
359    o OBCS: extend application of tracer open boundary conditions
360      to a strip beyond the boundary of width Olx/Oly
361    o add call monitor to TAF set of required calls (flow directives)
362      and include in natl_box_adjoint
363    o untangle a few ifdefs related to cost, ctrl, autodiff
364      untangel a few ALLOW_ECCO_OPTIMIZATION
365    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
366      (theta2, salt2 in ecco_cost_weights)
367    
368    checkpoint56c_post
369    o OBCS as control variables
370      - update ctrl_ad_diff.list, obcs_ad_diff.list
371      - remove balance of obcs controls from default
372      - fix index bug nobcs in ctrl_init
373      - fix dummy fields filen in ctrl_pack
374      - add dummy weights for obcs
375    o lsopt: comment out fort.94 output
376    o optim:
377      - remove unnecessary header files
378      - adjusted namelists
379      - add xerbla.F to Makefile
380    o exf:
381      - multiple modifications of exf_check_range
382      - unit change in exf_init_runoff from [m/year] to [m/s]
383    o mdsio:
384      - i/o-vector change debugLevel from debLevA to debLevB
385    
386    checkpoint56b_post
387    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
388      is called from DO_THE_MODEL_IO
389      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
390      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
391      - clean up PTRACERS_WRITE_TIMEAVE a little
392    o add another verification experiment that tests both the cfc-pkg and
393      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
394      reactive tendencies treated inline with regular timestepping
395    o testreport previously did a lousy job of comparing small numbers, so
396      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
397      implemented in the little c-progam tmp_cmpnum.c which is embedded in
398      testreport.
399    o ptracers_monitor: bug fix for MPI
400    
401    checkpoint56a_post
402    o GCHEM: finish reorganizating the package
403      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
404        (introduces another 3D-array for each passive tracer, but only if
405        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
406        gchemTendency is not needed because the timestep is done separately)
407      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
408      - GCHEM is now---more or less cleanly---separate from PTRACERS
409      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
410        so clear to me how that should be done in a general way.
411    o CFC: improve formatting of output in CFC_ATMOS
412    o PTRACERS:
413      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
414        that ALL experiments with ptracers enable can be checked. This makes
415        GCHEM_MONITOR obsolete.
416      - include a runtime parameter PTRACERS_monitorFreq that defaults to
417        monitorFreq
418      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
419    o add PTRACERS (PTR0[1-5]) to testreport output
420    o exf_check_range:
421      * default changed to .TRUE.
422      * will check values for niter0 if debLevA, every timestep if debLevB
423      * STOP in exf_check_range if 'out of range'
424      * range chosen generous to allow for potential extema
425      TBD: a version with stricter range
426           permitted range would be runtime parameters
427    o GMredi:
428      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
429      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
430      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
431    o GCHEM:
432      - move call to GCHEM_FORCING_SEP, so that it is now called before
433        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
434      - introduced a useGCHEM runtime flag and applied it everywhere.
435      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
436        this flag is now only visible within GCHEM-pkg routines.
437      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
438        be replaced by a 3D array that is computed before thermodynamics; for
439        this, the tracer ID iTracer had to be included into the parameter list
440        of ptracers_forcing
441      - set up forward_step to call gchem_forcing, that will replace
442        gchem_forcing_int in ptracers_forcing
443      - cleaning up
444    o small cleaning of exch2: remove files that are also in eesupp/src
445    
446    checkpoint56
447    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
448    o mnc: cleanup "full" files--fixes out-of-memory problem
449    o ECCO-GODAE
450      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
451      * fully merged and updated from SIO code
452        windstress sign change affects
453        - exf_inscal_[u/v]stress
454        - sign of xx_tau[u/v] adjustments
455        - signs in cost_scat
456      * ctrl_get_gen: avoid update of tau[u/v] for first few days
457      * natl_box_adjoint updated and compressed
458      * 2-level checkpoint switch added
459        (tested in EXP. 1 of natl_box_adjoint)
460      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
461    o SVD
462      * first complete, non-hacked version for SVD calculations
463      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
464        performed via direct access files admtlm_vector.it????
465        (via ctrl_[un]pack)
466      * optimcycle is used for ARPACK iteration counter
467        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
468      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
469        and add linear transforms where necessary
470      * controls are initial/final SST, SSS (can be extended; need to check
471        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
472    o mdsio: filename info to both stderr, stdout
473    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
474      from sign change
475    
476    checkpoint55j_post
477    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
478      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
479    o add consistent build directories and .cvsignore files to verification
480    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
481    o make all subroutines 30 or less characters in length for certain older
482      compilers to work (a thorough search only turns up two routines in
483      pkg/ptracers)
484    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
485      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
486    
487    checkpoint55i_post
488    o change arrays for total vertical diffusivity (2.D if explicit,
489      3.D if implicit) ; each ptracer uses its own background value.
490    o added mnc/NetCDF output capability to ocn_compon_interf
491      - added bits to verification/cpl_aim+ocn so that it can run on
492        ITRDA and other clusters without the mpirun "-wd" option
493    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
494      configuration
495    o give MNC the ability to create additional files rather than
496      exceeding a specified file size limit "MNC_MAX_FILESIZE"
497      - the default is just less than 2GB which is a practical limit
498        on many systems
499    o Compute the non-local term using either KPP vertical diffusivity (=default)
500       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
501    
502    checkpoint55h_post
503    o add verification test "vermix"
504    o remove all the *_ioinc flags and replace with the single global
505      outputTypesInclusive flag
506    o allow to set a vertical profile of vertical diffusivity for T & S
507    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
508    o useMNC moved from data.mnc to data.pkg
509    
510    checkpoint55g_post
511    o Renaming carbon AD experiments to comply with testreport conventions
512    o Updating adjoint of Held-Suarez hs94.1x64x5
513    o Fixing directives for non-ECCO forward_step, after ECCO directives
514      have been fixed to avoid recomp. of do_oceanic_phys
515      Works well for global_ocean.90x40x15,
516      but recomp. issue remains for carbon
517    o Updating adjoint output for natl_box_adjoint after
518      pkg/ecco has been modified (see taga c55d_post)
519    
520    checkpoint55f_post
521    o rename to timeave_init_fixed
522    
523    checkpoint55e_post
524    o some delicate re-shuffle of store directives to avoid one
525      extra call of do_oceanic_physics
526      affects ecco_the_main_loop.F, do_oceanic_physics.F
527      checkpoint_lev1_directives.h
528    o NB: this may break global_ocean adjoint temporarily,
529      but it is clear how to fix it. Will do later, need this now.
530    
531    checkpoint55d_post
532    o ECCO specific cost function terms (up-to-date with 1x1 runs)
533    o ecco_cost_weights is modified to 1x1 runs
534    o modifs to allow observations to be read in as
535      single file or yearly files
536    o enable to read exf forcing fields as either
537      single file or yearly files (flag useExfYearlyFields)
538    checkpoint55d_pre
539    
540    o switch between 2-level and 3-level checkpointing
541    o add ability of MNC to write local and "partial" (eg. 2D slices where
542      the full 3D field is never actually stored) arrays to NetCDF files
543      with the correct (that is, the complete multi-dimensional) set of
544      array indicies
545      - used in mom_vecinv() to write the diagFreq output
546      - tested (demonstrated) in verification/aim.5l_cs
547    o further mnc-ification
548      - add verification/lab_sea to the list with mnc setups
549      - fix undefined mnc v-names in cd_code
550      - add kpp to mnc output (both snapshot and timeave)
551    o non-hydrostatic code
552      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
553        in calc_gw.F
554      - defaults to viscAh
555      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
556        friction or Leith) in non-hydrostatic mode, as long as there is
557        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
558    o pkg/cost
559      extend simple cost functions to treat time mean quantities
560      (T,U,V) via cost_accumulate_state from cost_tile
561    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
562        be 2 times larger than the minimum size the advection scheme requires.
563        now get a perfect conservation of salt in advect_cs test-exp (updated)
564    o GGL90 (Gaspar's TKE mixed layer)
565      - add horizontal diffusion of TKE, requires exchanges in
566        do_fields_blocking_exchanges, horizontal diffusivity is zero by
567        default. In OPA there is no horizontal diffusion of TKE but the
568        mixing coefficients are computed from a horizontal average of TKE of
569        6 points or so. I think that diffusion has a little more physical
570        justification.
571      - clean up ggl90_calc in the hope of reducing memory usage (this hope
572        was in vain)
573      - mask tke-variable in ggl90_init
574    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
575    o fix biharmonic diffusion on CS-grid.
576    o more obcs stuff
577      - added obcs_external_fields_load as an alternative to the EXF-pkg option
578        for reading boundary values. This routine is called from
579        obcs_prescribe_read
580      - updated obcs_check
581      - changed sponge layer relaxation parameter units for days to seconds
582      - turned off sponge layer by default
583      - changed argument list of OBCS_CALC to myTime+deltaTclock
584      - fixed about 35 bugs in obcs_external_fields_load
585    
586    checkpoint55c_post
587    o obcs stuff
588      - new runtime flags useOBCSprescribe, useOBCSbalance
589      - re-arranged obcs_calc
590      - moved exf_getobcs to obcs_prescibe_read
591        obcs_prescibe_read is called after ORLANSKI stuff
592        and independent of it (executable can contain all).
593      - updated obcs_check
594      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
595        These may be necessary only if tangential velocities are
596        prescribed at OB, not sure, needs testing.
597    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
598      which simplifies the calls and passes the ifc check-bounds test
599    
600    checkpoint55b_post
601    o add a 2D scalar, Z location, exchange_2 routine.
602    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
603      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
604      affects advect_cs results (for the wrong reason): update output.txt
605    o use a more standard discretization for biharmonic viscosity ;
606     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
607      affects results of dome set-up: update output.txt
608    o fix gad_advection.F (CubedSphere part), back to version 1.23
609    o fix bug in mom_vi_del2uv.F (CubedSphere part).
610    
611    checkpoint55a_post
612    o merged code to
613      * prescribe/read time-dependent open boundaries
614        (works in conjunction with exf, cal)
615      * sponge layer code for open boundaries
616      * each boundary N/S/E/W now has its own CPP option
617        (healthy for the adjoint)
618    
619    checkpoint55
620    o up-to-date adjoint of previous breaks
621      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
622      - global_ocean_ebm: adjoint still needs fix (TLM ok)
623      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
624      - carbon: * remove tr1-related adjoint verification
625                * add ptracer as control variable
626    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
627      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
628    
629    checkpoint54f_post
630    o in verification/carbin/ remove experiment related to
631      ALLOW_PASSIVE_TRACER (array tr1 etc)
632      code_ad/ input_ad/ results_ad
633    
634    o add two new packages
635      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
636        + subject to optimization (memory)
637      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
638        + subject to reordering (many GOTOs in the original code)
639        + so far opps is called for every (i,j) point, and then operates in
640          the vertical; one may want to reorder the scheme in order operate in
641          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
642          fields)
643    o overhaul of IO so that we now have flags for MDSIO and/or MNC
644      - all verification tests compile and run with linux_ia32_g77
645      - defaults are compatible with current input files--nothing
646        should change if you were not previously using MNC
647      - MNC output has been added in numerous places (eg. timeave)
648        but there are still a few writes not yet do-able with MNC
649        (this is in progress)
650      - flags now allow for either/or/both use of MDSIO and MNC and
651        documentation will soon follow
652      - numerous small formatting cleanups for ProTeX
653    o add version info (via BUILD_INFO.h) to MNC and stdout
654    
655    checkpoint54e_post
656    o add two new packages
657      - pp81 (Packanowski and Philander, 1981), Richardson number and
658        stratification dependent mixing
659      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
660      - these scheme operate in a similar manner as KPP (without ghat, of
661        course), however there is only one diffusivity that is used for both
662        temperature and salinity (and passive tracers)ç
663    o add offline package
664    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
665      provided by Stephanie Dutkiewicz
666    o genmake2: add ability to search for C compilers and cleanup test output
667      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
668    
669    checkpoint54d_post
670    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
671    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
672      leading to additional shift by 5 days each year of integration
673       (i.e. leading to considerable offset over the years)
674    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
675    o start with no AB and no initial filtering (staggerTimeStep):
676      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
677    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
678      (external loading & cpl import/export stay in forward_step.F)
679    o update coupling interface to work with new staggerTimeStep
680    o change MDSIO ptracers_pickup.
681    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
682    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
683    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
684    
685    checkpoint54c_post
686    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
687      this affects (truncation error) output.txt of test-exp:
688       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
689    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
690    o change Qnet to always be the net heat flux, (+upward).
691      affects (truncation error) output of natl_box exp.: updated
692    o define the max number of passive tracers in PTRACERS_SIZE.h
693    o start to test mnc routinely in exp0
694    o add sea-ice loading (sIceLoad) as a new forcing field.
695    
696    checkpoint54b_post
697    o add testreport "-j JOBS" option for parallel builds (tested and pretty
698       impressive on Altix and Opteron systems)
699    o diagnostics can now write NetCDF files through the mnc package
700    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
701    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
702    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
703      affects (truncation error) output of lab_sea & natl_box exp.: updated
704    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
705    
706    checkpoint54a_post
707    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
708    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
709    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
710    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
711      + internal_wave (shift in writing cg2d_ini_res)
712    checkpoint54a_pre
713    
714    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
715      - modified verification/lab_sea and natl_box_adjoint accordingly
716    
717    checkpoint54
718    checkpoint53g_post
719    o prepare splitting of thermodynamics: store convect.counter in common block
720    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
721      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
722    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
723    o new parameter "nShapS": allow to treat differently S from T (nShapT)
724    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
725    o restore adjointability
726    
727    checkpoint53f_post
728    o modifications that affect AIM experiment results (update output.txt):
729      - no advection of S at top interface Nr (pkg/generic_advdiff)
730      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
731    o AIM pkg:
732      - include stability function into surf.Flux derivative relative to Tsurf
733      - calculate clear-sky radiation & surface temp. change (for diagnostics)
734    
735    checkpoint53e_post
736    o merged cylindrical coord configuration
737    o added rotating_tank experiment
738    checkpoint53e_pre
739    
740    checkpoint53d_post
741    o faulks upgraded: re-generate output.txt that have changed:
742       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
743    o Added Bryan and Lewis, 1979, vertical diffusivity profile
744    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
745    o added Sadourny discretization of Coriolis
746      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
747      - re-enabled use of omega3 (useAbsVorticity)
748    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
749      vector-invariant equations
750      - note: does *NOT* yet use same variable visc. for no-slip BC's.
751    o recoded the lateral boundary conditions for non-hydrostatic w, this time
752      hopefully without new bugs
753      - still to do: biharmonic friction for non-hydrostatic w
754    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
755    o regenerated output for global_ocean_ebm (using -ieee)
756    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
757      of mom_common/
758      - simple re-arrangement of instructions within computing loop
759    checkpoint53d_pre
760    
761    checkpoint53c_post
762    o new version of coupler for AIM+thSIce and Ocean models
763     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
764     - land: change Evaporation of snow
765     - aim with thSIce: fix bug in snow-precip.
766    o changes to calc_gw.F
767     - bug fix for w^2 term near the bottom boundary
768     - (hopefully) improve the lateral slip boundary condtions for use with
769        partial/looped cells
770      - because the bug fix changes two verification experiments anyway (exp5
771        and plume on slope), change the lateral boundary condition from half slip
772        to the value of no_slip_sides
773    o ebm package wasnt quite up to the parallel task. Fixed that.
774    o Adjoint of EBM package + verification
775      * TLM OK
776      * ADM not sufficient accuracy yet (needs further testing)
777    
778    checkpoint53b_post
779    o Commiting new energy balance model to repository
780      * package is pkg/ebm
781      * verif. is verification/global_ocean_ebm
782      * references are in ebm_driver.F
783    C      * X. Wang, P. Stone and J. Marotzke, 1999:

795    o Will need long integration testing.
796    checkpoint53b_pre
797    
798    o created pkg/mom_common in preparation for variable viscosity code
799    o renamed and split ini_mnc_io
800    o pkg/land: only liquid water can diffuse or run-off
801    o AIM using land: soil wetness availability account for snow
802    o added printMapIncludesZeros to EEPARMS namelist
803    
804    checkpoint53a_post
805    o restore TAMC compatiility for exf_constants.h
806      (no usage of _d in .h)
807    o Additional storing in KPP in an attempt to fix
808      TAMC problem with adjoint of KPP code.
809      (no success...)
810      Identical code works fine with TAF.
811    o Fixed verification/natl_box_adjoint experiments.
812      Initial conditions for Experiments 4 and 5 are now
813      set to "SEAICE_initialHEFF=0", which is more reasonable,
814      and hence gives results closer to that of Experiment 2.
815      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
816    
817    checkpoint53
818    o stable checkpoint with up to date adjoint
819      TLM tests only run for 1st grdchk at the moment. Its unclear if
820      this is a code problem or a problem with resetting code for g_
821      variables that is being autogenerated wrong.
822      Otherwise:
823       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
824       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
825         are both still in chaos following their security messes.
826    
827    checkpoint52n_post
828    o various build (mostly genmake2) changes including:
829      - ability to build/run more easily within Cygwin and MacOS X
830      - more complicated Makefiles with a stronger dependence on Gnu Make
831    o pkg/seaice modifications
832      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
833        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
834        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
835      - changed proxy for geostrophic velocity and updated
836        verification/lab_sea/results/* accordingly
837      - removed ADI dynamic solver from pkg/seaice
838      - replaced all occurrences of 1/CSTICE or 1/CSUICE
839        they caused a segmentation fault under certain circumstances
840      - removed unused field WATR
841    o bug fix in exf-package:
842      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
843         now reflect that.
844    o small fixes in the cal-package:
845      - set reference date to first of January for the 'model'-calendar
846      - failing of cal_CheckDate in cal_FullDate now actually results in a
847        warning
848    o small modifications in exf-package to increase flexibility:
849      - change climtempfreeze from a constant to a runtime parameter that
850        is specified in data.exf_clim (default = -1.9)
851      - introduce runtime parameter windstressmax (default = 2.0) that is
852        specified in data.exf
853    o fix in pkg/thsice:
854      - update Evap (Tsf changes) to be consistent with Latent heat flux
855      - maintain snow precipitation unchanged (even if Tsf >=0).
856     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
857    
858    checkpoint52m_post
859    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
860      this does not change any of the results, because myIter=0 in swfrac always
861      lead to jwtype=2 (the default anyway), but the call makes little sense
862      as a default
863    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
864    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
865      atmospheric model (AIM) to use it ; add a "slab ocean" component.
866    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
867    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
868    o extending useSingleCpuIO option to work with new exch2 I/O format
869      - old-style, missing-tile I/O is still accessible by defining CPP
870        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
871    o monitor package can write to NetCDF files and/or STDOUT
872    o fix re-definition bug in MNC_GRID_INIT_ALL()
873    o doc/api_reference added
874      - a framework for building an API Reference Manual using all
875        the "protex" comments embedded in the code
876      - see pkg/generic_advdiff, pkg/mnc for examples
877    o MNC:
878      - make myThid the last argument for all subroutines
879      - new default for the grid files: NO halos
880      - add useMNC and other run-time flags
881      - separate per-file-group handling of the unlimited dimension
882      - early initialization of MNC w/ flags read at the eeboot stage
883        and lookup tables set in initialize_fixed
884      - write all MNC output to a freshly-created directory
885    o thermodynamics sea-ice (thsice) is now tested with testreport.
886    o test exp. advect_cs: use the standard cs32 grid ; update output.
887    o Added functionality to grdchk:
888      pick global i,j,k position (or nearest wet) where to perform check.
889    
890    checkpoint52l_post
891    o new land formulation:
892      a) use ground enthalpy as prognostic variable to ensure exact
893         energy conservation.
894      b) account for water temperature and for latent heat of freezing
895         in all processes (rain, run-off, ground storage)
896      c) compute surface and ground temperature implicitly.
897    o aim_v23 modification for new land model:
898      a) Treat separately land / ocean / sea-ice surface fluxes
899         to allow implicit computation of land & sea-ice surface temp.
900      b) add snow precipitation.
901    checkpoint52l_pre
902    
903    o fix problem (when 1 tile is empty) in min/max monitor.
904    o fix bug in timeAve (u,vZetatave in common block)
905    o no restoring terms under ice for pkg/seaice
906    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
907    o bug fix for pkg/seaice pickups
908    o change MNC call locations and add coordinate attributes
909    o mask vorticity at the corner ; affects global_ocean.cs output
910    o fix ini_curvilinear_grid ; test CS experiments with mpi
911    o aim.5l_cs: modify sea-ice fraction input file ; update output
912    o exf: Adding simple range check routine for exf fields after read
913    
914    checkpoint52k_post
915    o removed top-level directory "diags"
916      - we migrated these functions to pkg/timeave a long time ago
917    o fixed bug introduced in pkg/monitor
918    o accuracy ctrlprec = 32 insuffient for gradient checks using
919      averaged fields (I/O via cost_averages)
920      -> use ctrl.h in active_file*.F to control I/O precision.
921    o paramter list of CALL ADTHE_MAIN_LOOP
922    o added initial do_the_model_io to ecco
923    o set all ...Freq to zero after cost_final
924      taveFreq, dumpFreq, pChkptFreq
925    o MAIN and ECCO differentiability restored
926    
927    checkpoint52j_post
928    o fix nchklev in tamc.h for global_ocean...
929    o Bringing flow and store directives up-to-date
930    o Really weird thing!
931      call do_the_model_io from the_main_loop with parameters
932      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
933      TAF places a faulty re-call of initialise_varia
934      after cost_final call which should not be there!
935    checkpoint52j_pre
936    
937    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
938      error messages
939    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
940    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
941      debug output
942    o modfied mdsio_writefield.F to handle non-global files under exch2
943    o update AIM Cubed-Sphere exp (aim.5l_cs):
944      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
945    o update AIM Equatorial Channel exp:
946      use standard aim_v23 pkg and change the SST fields to be more realistic.
947    o globalFile now works with exch2
948    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
949      mon_vort3.F to make exch2 friendly with >1 tile per cube face
950    o limit timeave output for hi-res integrations
951    
952    checkpoint52i_post
953    o removed CPP_EEOPTIONS.h from verification/*/code
954    o updated the tiling for global_ocean_pressure
955    checkpoint52i_pre
956    
957    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
958      the old pkg/aim).
959    
960    checkpoint52h_pre
961    o shortened offending lines in exch2_send_rx?.template
962    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
963    o genmake2: add build & execute test for NetCDF code
964    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
965      old grid files, moved CPP_EEMACROS.h to pkg/exch2
966    o added useSingleCPUIO flag to monitor.F and mon_out.F
967    o added temporary hack for sea-ice dynamics on the cube:
968      metric terms are ignored and it is assumed that
969      there is no sea-ice on cube faces 1, 2, 4, and 5.
970    
971    checkpoint52f_post
972    o added exch2 cube routines to pkg/exch2
973    o modified hs94.cs-32x32x5 to use it
974    o added new grid files to hs94.cs-32x32x5
975    checkpoint52f_pre
976    
977    checkpoint52e_post
978    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
979      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
980    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
981      to work with implicit vertical advection and AB ;
982    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
983    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
984     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
985    checkpoint52e_pre
986    
987    o fix bug in impldiff when Nr=1 or Nr=2.
988    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
989    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
990    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
991      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
992    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
993    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
994    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
995    
996    checkpoint52d_post
997    o re-tiled many expts to allow comparison in multi-processor mode
998      - updated output accordingly
999      - changed hs94.128x64x5 to use intial T from file rather than use the
1000        random number generator
1001    o add infrastructure in model routines for fizhi and gridalt packages
1002    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1003    o changes to permit hi-res, cubed-sphere, configuration
1004      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1005      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1006      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1007        of surface winds for the cube
1008      (A verification experiment, based on global_ocean.cs32x15, but with
1009       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1010       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1011       complete with example surface forcing files and matlab scripts to look
1012       at the output and compare it with that of global_ocean.cs32x15.)
1013    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1014       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1015       to conform to the common rule.
1016    o check-in the first version of the coupler + interfaces for multi-components
1017       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1018       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1019       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1020       - ocean and atmos. share the same horizontal grid (no interpolation).
1021       - exchanges between component and coupler is done in forward_step
1022    o new verification experiment, cpl_aim+ocn:
1023       coupled ocean - AIM atmosphere on cs32 grid.
1024    
1025    checkpoint52d_pre
1026    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1027    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1028    
1029    checkpoint52c_post
1030    o Fixing OPTIONS files for use of exf:
1031      - ALLOW_ECCO not needed
1032      - ECCO_CPPOPTIONS.h should not be included from
1033        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1034        as has been the case in the past
1035      - All cal/exf related options are currently set in
1036        single header file. Should remain so until we
1037        agree on a consistent new policy.
1038    o Removed all CPP options for cal package.
1039      cal has no more CPP options.
1040    o modified STOREs in GAD_ADVECTION
1041    o corrected key comp. for passkey
1042    
1043    checkpoint52b_post
1044    o new version: "thsice" of thermodynamic sea-ice pkg:
1045     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1046     - modify fluxes but do not change theta directly;
1047     - light cleaning of bulk_force pkg (still needed with thsice).
1048     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1049       + output_thsice.txt to test thsice & bulk_force pkgs.
1050    o put back grid & coriolis monitor output.
1051    checkpoint52b_pre
1052    
1053    o call "do_the_model_io" at the beginning (=> dump initial state)
1054    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1055    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1056      (need info on NUMBER_OF_PTRACERS)
1057    o missing PTRACERS headers in some routines
1058    o default tamc.h in pkg/autodiff supposed to crash
1059      to ensure proper customization
1060    
1061    checkpoint52a_post
1062    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1063      - moved surfaceTendencyTice from pkg/seaice to main code
1064      - subroutine FREEZE_SURFACE now limits only surface temperature
1065        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1066        => new output.txt for global_ocean.cs32x15 & global_with_exf
1067      - keep the old version of FREEZE for backward compatibility;
1068        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1069      - corresponding modifs for TAF directives
1070    o added surface flux output variables to TIMEAVE_STATVARS
1071    o time-averaged output for pkg/ptracers
1072    o fix problem with ECCO-related divided adjoint
1073      snapshot file was missing some ad-variables,
1074      but no warning issued by TAF
1075    
1076    checkpoint52a_pre
1077    o some bug fixes for #undef REAL4_IS_SLOW
1078    
1079    checkpoint52 = ecco_c52_e35
1080    o after testing adjoints of checkpoint51u_post
1081    
1082    checkpoint51u_post
1083    o this is the post-merge tag of the ecco-branch
1084      (needs another clean checkout and re-testing)
1085    o various natl_box_adjoint configs and results
1086      but no input fields
1087    o obcs adjoint not yet merged!
1088    o adding ECCO global 1x1 and 2x2 degree configs
1089    o updated/extended some store directives for seaice
1090    o pkg/ecco now containes ecco-specific part of cost function
1091    o top level routines the_main_loop, forward_step
1092      supersede those in model/src/
1093      previous input data.cost now in data.ecco
1094      (new namelist ecco_cost_nml)
1095    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1096    
1097    checkpoint51t_post
1098    o this is the pre-merge tag of the ecco-branch
1099    
1100    checkpoint51s_post
1101    o cleanup: removed various obsolete #define-s
1102    o pkg/grdchk
1103      - renamed 'ph-grd 3' to 'grad-res'
1104      - merged from ecco-branch
1105        (remaining bug fixes for obcs gradient checks)
1106      - additional high-precision output for testreport
1107        (grep for 'precision_grdchk_result')
1108    
1109    checkpoint51r_post
1110    o cleaned up or removed CPP_OPTIONS.h files
1111    o updated results for some of the tests to reflect the new
1112      optfiles (-ieee: -O0 instead of -O3)
1113    
1114    checkpoint51q_post
1115    o cd_code:
1116      - moved cd_scheme.F -> cd_code_scheme.F
1117      - separate read_checkpoint from cd_code_ini_vars.F
1118      - separated cd_code part from write_checkpoint
1119      - updated AD_SOURCE, generated .flow
1120      - added CD_CODE_VARS.h to the_main_loop
1121      - Moving cd_code specific store dir.s to pkg/cd_code
1122    o ctrl package totally restructured
1123      - pack/unpack now optional and decoupled from
1124        xx_/adxx_ I/O
1125      - ctrl_pack/unpack cleaned
1126        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1127      - confined inclusion of AD_CONFIG.h to where necessary.
1128    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1129    
1130    checkpoint51p_post
1131    o create initial cd_code package
1132      - WARNING: the initialization of fields within packages
1133        is broken because INI_FIELDS (where READ_CHECKPOINT is
1134        called) is called *before* PACKAGES_INIT_VARIABLES.
1135        This seems to be backwards since
1136        1) its important to initially zero the entire field including
1137           the "halo" region
1138        2) zeroing needs to be done *before* reading pickup info
1139           and the pickup call might or might not happen in any
1140           particular run
1141      - this needs an overhaul for R2
1142    o cleanup verification/*/code/GMREDI_OPTIONS.h
1143    o cleanup testreport
1144    
1145    checkpoint51o_post

1280    
1281    checkpoint51e_post
1282    o pkg/mom_vecinv:

1307      - debLevA: standard
1308      - debLevB: equivalent to current debugMode=.TRUE.
1309    o introducing pathname variable mdsioLocalDir for mdsio
1310      that can be specified at runtime
1311      (relevant for cluster I/O to local disk)
1312    `
1313    >>>checkpoint51b_post
1314    adjoint of ptracers
1315    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
1316    o extended state in checkpoint_lev?, etc.
1317    o alternative ctrl/cost with tr1 or ptracer
1318    o new comlev1_bibj_ptracers
1319    o new ptracers.flow
1320    o made ptracers_forcing same as external_forcing_s
1321    o added verification for adjoint with ptracers
1322      - adm. grdchk fail so far
1323      - tlm. grdchk OK
1324      - checked tapelev/comlev recomputations: OK
1325    <<<checkpoint51b_pre
1326    
1327    checkpoint51a_post

1332      - in model/src and pkg/ptracers
1333    
1334    checkpoint51
1335    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1336      - autodiff, ctrl, exf, grdchk, seaice
1337      kept separate packages
1338      - cost, ecco, obcs
1339    o updating verification/internal_wave, verification/lab_sea
1340      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1341    
1342    checkpoint50i_post
1343    o Preparing next differentiable checkpoint and sync
1344      of MAIN vs. ecco-branch
1345      - 1st step: this one is differentiable
1346      - 2nd step: next(! not this) checkpoint will have updated packages
1347                  from ecco-branch)
1348    
1349    checkpoint50h_post
1350    o new package "land": provide surface BC for AIM.
1351    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1352    o AIM: use true log-P extrapolation for near surface temp (= as in
1353        F.Molteni paper) ; update aim.5l_cs output.
1354    o New variable in PARM03 for more flexible pickups
1355    o somewhat cleaned package initialisation sequence for
1356      ctrl/ cost/ ecco/ in packages_... routines
1357    
1358    checkpoint50g_post
1359    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1360      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1361      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1362        made the default because of faster convergence than ADI
1363    
1364    checkpoint50f_post
1365    o exf totally restructured
1366      - replaced all exf_set_ routines by one generic exf_set_gen.F
1367        and made sure it's still differentiable
1368      - split exf_getffields.F into new exf_bulkformulae.F
1369      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1370      - updated adjoint/makefile and relevant verif. accordingly
1371    
1372    checkpoint50f_pre

1381    
1382    checkpoint50e_post
1383    o make KPP work with PTRACERS
1384     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1385       nearly a copy of kpp_transport_s
1386     - there is no analogue to SurfaceTendencyS, so I have to use
1387       gPtr(of the surface layer) instead
1388    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1389    checkpoint50e_pre
1390    
1391    checkpoint50d_post
1392    o change kpp output from multiple-record state files to single-record state
1393      files analogous to write_state.F
1394    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1395      analogous to the cg2d-related output.
1396    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1397      so that writing to internal file fn (with length 512) fails.
1398    checkpoint50d_pre
1399    
1400    checkpoint50c_post
1401    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1402    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1403    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1404    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1405    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1406    
1407    checkpoint50c_pre
1408    Merging from release1_p13:
1409    o bug fix for pkg/seaice dynamic solver
1410    o Added SEAICE_initialHEFF to pkg/seaice
1411    
1412    checkpoint50b_post
1413    o store u*,v* in gU,V instead of in guNm1,gvNm1
1414    o in order to put the momForcing out of the Adams-Bashforth:
1415      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1416      to timestep.F
1417    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1418    o re-generate output for highly sensitive test-exp:
1419       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1420    
1421    checkpoint50b_pre
1422    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1423    o corrected CPP option mismatch in exf_Bulk... functions for case
1424      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1425    
1426    checkpoint50a_post
1427    o Bug fix for merging between c50 and KPP.
1428      ikey was passed from thermodynamics to kpp_calc via
1429      common block rather than being recomputed in kpp_calc,
1430      in contradiction with new key itdkey.
1431      New key ikppkey created, and tamc.h headers updated.
1432    
1433    checkpoint50
1434    - 2nd step of merge with ecco-branch:
1435      merge changes in ecco-branch back into main trunk
1436    - bug fix in find_alpha
1437    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1438    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1439    - merged some sliced AD support routines
1440    
1441    checkpoint49
1442    merged from ecco-branch:
1443    o exf:
1444      - Enable initialisation of forcing fields to constant
1445        (runtime) values.
1446      - in exf_getffields.F
1447        Reduce i-/j-loop to interior domain, discarding overlaps.
1448        That also fixes wrong TAF-key computations for key_1, key_2
1449        with bulf formulae.
1450      - exf_init.F modify #ifdef for exf_init_evap
1451      - exf_getffieldrec.F, ctrl_getrec.F
1452        The following INT-usages are not safe:
1453          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1454          fldcount = int(fldsecs/fldperiod) + 1
1455        and were modified.
1456    o autodiff: checkpoint_lev...
1457      - updated storing for bulk formulae (some arrays were missing)
1458      - added state for seaice package
1459      - synchronized with main branch
1460    o DIVA:
1461      Modif.s in
1462      - the_main_loop.F
1463      - the_model_main.F
1464      and added cost_final_restore.F cost_final_store.F
1465      o With these changes, it is possible to fully separate
1466        the first forward run to compute the cost function (mdthe_main_loop)
1467        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1468        into separate model executions.
1469        This enables better tuning of DIVA to given queue sizes.
1470      o Loss of cost function value in consecutive DIVA runs is
1471        fixed by storing to 'costfinal' file.
1472      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1473        beginning/end of adjoint integration is accounted for.
1474      The current changes apply to TAF-1.4.26.
1475      TAF has one remaining bug, requiring one manual change
1476      (see MITgcm manual).
1477    o cal: synchronized between MAIN and ecco-branch
1478    
1479    checkpoint48i_post
1480    o Changes to restore differentiability of code w.r.t. previous tag
1481      (mostly adding new routines to make list and replacing
1482      pressure by totPhiHyd).
1483    o Updated and merged grdchk package
1484      - has both ADM and TLM checks
1485      - works for single- and multi-proc.
1486      - output cleaned
1487      - worked successfully for parallel DIVA
1488    o genmake:
1489      - Adding -platform=SP4
1490      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1491    o Modif. for DIVA:
1492      ctrl_unpack should not be called in intermediate DIVA interval.
1493      (similar thing would apply for active files such as
1494      tbar, sbar, psbar, which should not be reinitialised;
1495      only relevant for ecco-branch)
1496    
1497    checkpoint48h_post
1498    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1499    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1500    o Added SEAICE_initialHEFF to pkg/seaice
1501    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1502    
1503    checkpoint48g_post
1504    --- EOS:
1505    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1506      store total Potential in totPhyHyd for diagnostics & EOS.
1507    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1508    --- Pressure/geopotential gradient:
1509    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1510    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1511      ( changes results of global_ocean_pressure )
1512    o NLFS + z-coord.: add eta*Rho' contribution.
1513    o accurate phiHyd when using interface-W at the middle between 2 centers
1514     ( changes results of ideal_2D_oce )
1515    o includes r* 2nd term in potential gradient.
1516    
1517    checkpoint48f_post
1518    Merging from release1_p12:

1525      (SBO) core products, including oceanic mass, center-of-mass,
1526      angular, and bottom pressure (see pkg/sbo/README.sbo).
1527    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1528      to avoid negative values in shallow regions.
1529      - updated verification/natl_box/results/output.txt
1530      - updated verification/lab_sea/results/output.txt
1531    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1532    o Added useSingleCpuIO option (see PARAMS.h).
1533    o Updated useSingleCpuIO option in mdsio_writefield.F to
1534      work with multi-field files, e.g., for single-file pickup.
1535    o pkg/seaice:
1536      - bug fix in growth.F: QNET for no shortwave case
1537      - added HeffFile for specifying initial sea-ice thickness

1547    o dynamics: change definition of computational domain & adapt mom_fluxform
1548      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1549    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1550        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1551        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1552        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1553        inverted_barometer solid-body.cs-32x32x1
1554      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1555    
1556    checkpoint48d_post
1557    o in preparation for r*:
1558     a) use pre-computed gradient of hydrostatic potential:
1559        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1560     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1561        => affects results of glob_oce_pressure (different truncation error)  
1562      update output.txt of ideal_2D_oce & global_ocean_pressure
1563    
1564    checkpoint48d_pre
1565    o in preparation for r*:
1566      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1567      pass the 2 comp. of the grad. as arguments to momentum S/R.
1568      but for the moment, only used if it does not change the results.
1569    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1570    
1571    checkpoint48c_post
1572    Modifications in treatment of initial flux forcing controls
1573    to avoid extra storing of flux fields.
1574    
1575    checkpoint48c_pre
1576    o Added tidal_basin_2d experiment (currently 1D!)
1577    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1578    
1579    checkpoint48b_post
1580    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1581     (modification to pressure gradient not yet implemented)
1582    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1583      (for U & V) that are used for vertical advection of momentum.
1584    
1585    checkpoint48a_post
1586    o In preparation for r*, use temp. array to compute vertical transport
1587       in flux-form momentum pkg. => change results of few test-exp.
1588      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1589                        lab_sea, natl_box & plume_on_slope
1590    
1591    checkpoint48
1592    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1593    
1594    checkpoint47j_post
1595    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1596    o moved adexch from forward_step to addummy_in_stepping
1597    o added exch in ctrl_map_...
1598    o aveFreq.=0. at end of cost_final to avoid overwrite in
1599      reverse checkpointing loop
1600    o Yet more changes in gmredi:
1601      * adgmredi_calc_tensor
1602        avoiding all recomputation of gmredi_slope_limit
1603      * adgmredi_x/y/rtransport
1604        added flag for excessive storing to avoid recomp. of
1605        u/v/rtans, dTdx/y/z
1606        -> this is not really necessary and very memory-consuming
1607      * adgmredi_slope_psi:
1608        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1609      * gmredi_slope_limit
1610        re-activated full calculation of taperfct for case 'ac02'
1611    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1612    
1613    checkpoint47i_post
1614    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1615    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1616      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1617    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1618    o gmredi: fix few bugs.
1619    
1620    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1621    This will be a good checkpoint to plug into the ecco-branch.
1622    o few modif.'s to get latest version adjointed
1623      (mainly kick out code in ini_linear_phisurf)
1624    o modif's to run adjoint with exactConserv
1625    o case GM_BOLUS_ADVEC should be cleaned
1626      S/R gmredi_slope_psi should be cleaned
1627    o verification/carbon now has exactConserv=.TRUE.
1628    
1629    checkpoint47g_post
1630    o time-average AIM output: becomes independent from statvars time-average
1631      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1632    o After TAF bug fix:
1633      Tested adjoint of gmredi package.
1634      Tests were done with checkpoint47 rather than with latest
1635      checkpoint47f_post since the latter is broken for the adjoint
1636      verification/carbon/ contains both ADM and TLM gradient checks.
1637    Here they are, before they get changed/lost/stolen.
1638    Mostly modif.'s to fix numerical sensitivities.
1639    Gradient checks OK for
1640    - GM_taper_scheme:
1641      * clipping
1642      * ac02
1643      * linear
1644      * glw91
1645      * dm95
1646      * ldd97
1647    - GMREDI_OPTIONS:
1648      * GM_VISBECK_VARIABLE_K
1649      * GM_NON_UNITY_DIAGONAL
1650      * GM_EXTRA_DIAGONAL
1651      * GM_BOLUS_ADVEC
1652    in conjunction with data.gmredi parameters to be checked in
1653    in a few minutes under verification/carbon/code/
1654    
1655    checkpoint47f_post
1656    Merging from release1_p10:
1657    o modifications for using pkg/exf with pkg/seaice
1658      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1659        and SEAICE_EXTERNAL_FLUXES
1660      - pkg/exf CPP options EXF_READ_EVAP and
1661        EXF_NO_BULK_COMPUTATIONS
1662      - usage examples are Experiments 8 and 9 in
1663        verification/lab_sea/README
1664      - verification/lab_sea default experiment now uses
1665        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1666    
1667    checkpoint47e_post
1668    o created a tag prior to creating a branch
1669    
1670    checkpoint47d_post
1671    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1672      at the bottom boundary had an erroneous half slip boundary condition
1673    o added bottom drag and no slip boundary condition capabilities to
1674      oceanic pressure coordinates code
1675    o added new verification experiment global_ocean_pressure, this experiment is
1676      also described in the tutorial section of the manual
1677    checkpoint47d_pre
1678    
1679    checkpoint47c_post
1680    o Added a verification experiment for a global cubed-sphere ocean run
1681      -  verification/global_ocean.cubed32x32x30
1682      -  uses pkg/therm_seaice and pkg/bulk_forcing
1683    
1684    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1685    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1686      when using P-coordinate; only implemented for atmospheric config.
1687    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1688      NOTES: requires option NONLIN_FRSURF to be "#define".
1689    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1690    
1691    checkpoint47b_post
1692    Merging from release1_p9:
1693    o pkg/seaice
1694      - removed GOTO's and added taf directives
1695      - double precision constants to reduce the g77 (Linux)
1696        to F77 (SGI) differences reported in release1_p8
1697    o tools/genmake
1698      - added SGI options
1699    o verification/testscript
1700      - updated to that of checkpoint47a_post
1701    o verification/global_ocean.90x40x15/input/eedata
1702      - modified for SGI f77 compatibility
1703    o verification/lab_sea
1704      - added description of sea-ice model
1705      - added missing matlab routines
1706      - added test of thermodynamics parallelization
1707    
1708    checkpoint47a_post
1709    o new pkg: aim_v23
1710     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1711       for now, keep the same surface forcing as before.
1712     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1713     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1714     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1715    o add diagnostic of surface correction term in monitor output
1716    
1717    o bulk_force and therm_seaice
1718    - Two packages:  bulk_force (Bulk forcing)
1719      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1720    - Earlier integration from Stephaine Dutkiewicz
1721      and Patrick Heimbach.
1722    - Two ifdef statements for compile time,
1723       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1724    
1725    checkpoint47
1726    differentiable version of checkpoint46n_post
1727    o bug fix in quasihydrostaticterms
1728    o * "clean" adjoint code (in terms of extensive recomputations)
1729        can now be obtained for all GMREDI options (i.e. for
1730        - GM_VISBECK_VARIABLE_K
1731        - GM_NON_UNITY_DIAGONAL
1732        - GM_EXTRA_DIAGONAL
1733        - GM_BOLUS_ADVEC )
1734      * However, wrong gradient check problem remains unsolved.
1735      * New CPP options have been introduced for different
1736        tapering schemes
1737    o external_fields_load now part of differentiation list
1738    o pressure needs multiple storing;
1739      would be nice to have store_pressure at beginning or
1740      end of forward_step, e.g. by having phiHyd global (5-dim.)
1741      (NB: pressure is needed for certain cases in find_rho,
1742      which is also invoked through convective_adjustment).
1743    o recomputations in find_rho for cases
1744     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1745    o #define ATMOSPHERIC_LOADING should be differentiable
1746    o ini_forcing shifted to begining of initialise_varia
1747    o Incorporating QNVS line search routines into MITgcm
1748      (this is separate code, and therefore not under pkg)
1749      lsopt/, optim/
1750    o Updated verification/carbon/
1751      - #define GM_VISBECK_VARIABLE_K
1752      - GM_taper_scheme    = 'ldd97'    
1753    
1754    checkpoint46n_post
1755    Merging from release1_p8:
1756    o verification/natl_box:
1757      updating new external_fields_load routine
1758    o New package: pkg/seaice
1759      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1760      The sea-ice code is based on Hibler (1979-1980).
1761      Two sea-ice dynamic solvers, ADI and LSR, are included.
1762      In addition to computing prognostic sea-ice variables and diagnosing
1763      the forcing/external data fields that drive the ocean model,
1764      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1765      The implied surface heat flux is then stored in variable
1766      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1767      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1768      non-local transport term.  Because this call precedes model
1769      thermodynamics, temperature under sea-ice may not be "exactly" at
1770      the freezing point by the time theta is dumped or time-averaged.
1771      N.B.: fairly large differences in accuracy occur across
1772            different platforms/compilers; comparison between
1773            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1774            generated output gives:
1775       T           S           U           V
1776      C D M    c        m  s        m  s        m  s        m  s
1777      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
1778      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d
1779      g d e n  d  n  x  n  .  n  x  n  .  n  x  n  .  n  x  n  .
1780    
1781      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1782    o GAD:
1783      - generated new common blocks to account for call of
1784        same gad routines with differing traceridentities
1785        (needed to modify tracerIdentity indices in GAD.h)
1786      - generated separate common blocks for case useCubedSphereExchange
1787        (Department of Futurology)
1788      - parameter lists to gmredi_?transport: added tracerIdentity
1789      - added new key indices to tamc.h
1790    o external_fields_load:
1791      - added this routine to TAF list
1792      - needed to make some common blocks global and additional storing
1793        along the same lines as exf package (checkpoint_lev?_directives.h)
1794    o exf:
1795      updated external forcing package
1796      - bug fixes carried over from ecco-branch
1797        (missing OBCS_OPTIONS.h in two routines)
1798      - enable easy to use "no forcing".
1799      - added exf I/O for atmospheric loading
1800      - added exf I/O for runoff data
1801      - transfered scaling between exf <-> MITgcm to exf namelist
1802    o Adding new verification experiment global_with_exf.
1803      This verification experiment is almost identical to the
1804      global_ocean.90x40x15 experiment, except that it uses
1805      the exf (and cal) package instead of the
1806      external_fields_load routine (cf README file).
1807    
1808    checkpoint46m_post
1809    o modified testscript to return -- when there are no lines of "%MON" output
1810    o added new flag "quasiHydrostatic" for QH mode
1811      and new routine quasihydrostaticterms()
1812    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1813      New routine: mom_u_coriolis_nh()
1814    o fixed sign of non-hydrostatic metric terms in u and v equations.
1815      Depend on correct sign of gravitySign.
1816    o added work.pc* to .cvsignore in aim directories using ifc
1817    o introduced flag for controllin non-hydrostatic metric terms
1818    o removed gravitySign from PARM04
1819    o switched to g77/ifc from pgf77 in aim experiments
1820    
1821    checkpoint46l_post
1822    o made convective adjustment work with pressure coordinates:
1823     - changed the direction of k-loop in convective_adjustment.F for the
1824       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1825     - adjusted the reference pressure k-index in convective_adjustment.F
1826     - adjusted the convection condition in convect.F (in analogy to
1827       calc_ivdc.F)
1828     - convective_adjustment no longer computes anything on the halos
1829     - removed the warnings about negative salinity from find_rho.F and
1830       find_alpha.F; instead the new routine look_for_neg_salinity, called
1831       at the beginning of find_rho, find_alpha, and find_beta, does a
1832       check of the entire slice, if CPP-option
1833       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1834    checkpoint46l_pre
1835    
1836    checkpoint46k_post
1837    o fixed the verification/global_ocean.90x40x15 experiment:
1838     - new bathymetry (the world according to A., JMC, and M.)
1839     - new initial fields and forcing fields (*.bin files)
1840     - new POLY3.COEFFS (for the next release one should switch to a full
1841       equation of state: JMD95P or MDJWF)
1842     - fixed several errors and redundancies in the data file
1843     - experiment uses looped cells
1844     - added matlab directory with diagnostic scripts for plotting of output
1845    
1846    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1847     - read AIM physics parameters from a file (data.aimphys)
1848     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1849    
1850    checkpoint46j_post
1851    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1852    o move wVel computation at the end of the time step, in S/R integr_continuity
1853    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1854    o update timeave pkg for wVel diagnostic.
1855    checkpoint46j_pre
1856    
1857    checkpoint46i_post
1858    o Clean up AIM package (and keep the results unchanged):
1859      include CPP_OPTION and use IMPLICT NONE in all routines ;
1860      declare all the variables _RL ; use _d 0 for all numerical constants.
1861      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1862    
1863    checkpoint46h_post
1864    o cleaned up the use of rhoNil and rhoConst.
1865      - rhoNil should only appear in the LINEAR equation of state, everywhere
1866        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1867        and the dynamical equations are all divided by rhoConst
1868    o introduced new parameter rhoConstFresh, a reference density of fresh
1869      water, to remove the fresh water flux's dependence on rhoNil. The default
1870      value is 999.8 kg/m^3
1871    o cleanup up external_forcing.F and external_forcing_surf.F
1872      - can now be used by both OCEANIC and OCEANICP
1873    checkpoint46h_pre
1874    
1875     Added code to convert surface volume flux (fresh water) into
1876     a mass flux when using P coordinates in the ocean (OCEANICP).
1877     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1878    
1879    checkpoint46g_post
1880    o Include a new diagnostic variable phiHydLow for the ocean model
1881      - in z-coordinates, it is the bottom pressure anomaly
1882      - in p-coordinates, it is the sea surface elevation
1883      - in both cases, these variable have global drift, reflecting the mass
1884        drift in z-coordinates and the volume drift in p-coordinates
1885      - included time averaging for phiHydLow, be aware of the drift!
1886    o depth-dependent computation of Bo_surf for pressure coordinates
1887      in the ocean (buoyancyRelation='OCEANICP')
1888      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1889        Theta, Salinity, and Pressure in the parameter list. This routine is
1890        presently contained in find_rho.F. This routine does not give the
1891        correct density for 'POLY3', which would be a z-dependent reference
1892        density.
1893    o cleaned up find_rho
1894      - removed obsolete 'eqn' from the parameter list.
1895    o added two new verification experiments: gop and goz
1896      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1897    checkpoint46g_pre
1898    
1899    checkpoint46f_post
1900    o Enable tangent linear (forward mode) gradient checks:
1901      - extended active file handling to g_... files
1902      - added TANGENT_SIMULATION to theSimulationMode
1903      - extended grdchk package accordingly
1904    o added tangent linear setup in verification/carbon/code_ftl
1905    o added adjoint setup in verification/front_relax/code_ad
1906    
1907    checkpoint46e_post
1908    o Added new equation of state -> MDJWF
1909      - EOS of McDougall et al., 2002, JAOT, submitted
1910      - caveat: the equation of state is only valid for a smaller (more
1911        realistic?) range of values than JMD95P/Z and UNESCO
1912      - added masks to the calculation of pressure in store_pressure
1913      - added more check values for density in check_eos (ini_eos.F), some of
1914        the old check values are out of the range of the MDJWF-eos, so don't
1915        expect perfect matches for those
1916    checkpoint46e_pre
1917    
1918    checkpoint46d_post
1919    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1920      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1921      case of pressure coordinates. eosType='JMD95Z' in
1922      combination with buoyancyRelation='OCEANICP' now causes an error.
1923    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1924      in find_alpha/beta.
1925    checkpoint46d_pre
1926    
1927    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)

2018    
2019    checkpoint45a_post
2020    o compute Rho over the whole domain (extend iMin,jMin indices)

2088    o real fresh water flux implemented with non-linear free-surface.
2089    
2090    chkpt44c_pre,post

2145    o more mods for non-linear free-surface including new variable
2146    o modified multi-dim method to work on cube
2147    o bug fix in KPP (from DM)
2148

2160    o new package rw/
2161      Added method for dumping intermediate local arrays:
2162      mdsio_writetile - same as mdsio_writefield except works from inside
2163                        bi,bj loop
2164      mdsio_writelocal - same as mdsio_writetile except works for local
2165                         arrays
2166      write_local_r? - higher-level wrapper for mdsio_writelocal
2167      Controlled by diagFreq. Defaults to zero (ie. no dumps)
2168      Example given at end of mom_vecinv.F that dumps some local arrays.
2169    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
2170      control flux-form versus vector invariant code.
2171      Switch is runtime flag vectorInvariantMomentum (defaults to false)
2172      or genmake -DISABLE ...
2173    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
2174      (additional storing is now needed for case vecinv;
2175      currently nothing implemented to switch this storing off
2176      in case fluxform is used since no CPP flag available).
2177    
2178    checkpoint40pre7

2190    o Added diffkr, kapgm to control variables
2191    o bug fix in gmredi_slope_limit for ldd97
2192    
2193    checkpoint40pre5
2194    o proper initialization of Adams-Bashforth time stepping
2195      + uses forward step for very first step of model (iter=0)
2196    o re-generated *all* output since almost all output is modified by this
2197      change (sorry but we've been putting this one off for about 2 years)
2198      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
2199        *not* regenerated since they are already out of date and I don't
2200        want to create the impression that they are suddenly working.
2201    o removed KAP stuff for DEC's
2202    o modified/added many .cvsignore files in */code and */input
2203    o added new expt "solid-body.cs-32x32x1"
2204      + this uses an alternative form of ini_curvilinear_grid.F which
2205        is not necessarily any better than the current one...
2206    
2207    checkpoint40pre4
2208    o added re-initialisations of utrans,vtrans,rtrans in
2209      calc_common_factors which are crucial for TAF.

2230       in addummy_in_stepping
2231     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
2232     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
2233     o Included following packages:
2234       cal: calendar
2235       exf: external forcing
2236       ecco: essential routines to control use of cal, exf
2237             (NB: this is not the full ECCO environment)
2238     o disabled some packages by default in genmake
2239    
2240    checkpoint38
2241     o see notes_c37_adj.txt
2242     o corrected wrong layer index in external_forcing_t
2243     o replaced the_main_loop/forward_step by the_main_loop
2244     o removed forceoutput from write_state
2245       (replaced criteria for initial/final state)
2246     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
2247    
2248    checkpoint37
2249     o mdsio.F routine split and packaged in pkg/mdsio
2250       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
2251        used unless genmake -disable=mdsio)
2252     o allow a more precise surface-geopotential gradient for the atmosphere
2253       taking into account the change in space of Alpha (=1/rho) at the surface.
2254     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
2255       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
2256     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
2257       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
2258       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
2259     o Time-Average diagnostics defined as a pseudo package "timeave".
2260     o pickup files : old pickup (before c35) did not work with new code (c35
2261       and after) unless activating 2 commented lines in initialise-varia.
2262     o Non-Hydrostatic pickup file Pb fixed.
2263     o bug with Rigid-lid version (since c35) fixed.  
2264    
2265    checkpoint36
2266     o implement Crank-Nickelson barotropic time-stepping
2267     o recover Time-Average diagnostics
2268     o fix Pb in checkpoint (PR#19)
2269     o AIM become a standard package ; clean unused CPP_kees
2270    
2271    checkpoint35
2272     o subtantial rewrite of dynamics.f
2273     o allows staggered time-stepping
2274     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
2275     o added bottom drag (linear + quadratic)
2276    
2277    checkpoint34
2278     o Modified exchange routines for correct reverse simulation.
2279     o Added verification output to comply with bug fix in impldiff.F
2280       as of c33 (exp2, natl_box).
2281     o Corrected store directives in dynamics.F
2282     o Corrected array boundaries in impldiff.F
2283     o Corrected array dimensions in gmredi.

2287    
2288    checkpoint33
2289     o Fixed bug in lower BC in impldiff.F
2290     o Fixed confusion about units of forcing arrays in FFIELDS.h
2291       namely Fu,Fv,Qnet,Qsw,EmPmR:
2292       - Removed verification/natl_box/code/external_fields_scale.F
2293         (did not differ from that in model/src)
2294       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
2295         (see FFIELDS.h for description)
2296       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
2297         kpp_calc.F and kpp_transport_t.F
2298       - Removed model/src/external_fields_scale.F and calls to it
2299       - verification/natl_box uses flux data with "atmospheric" sign so
2300         a special version of external_fields_load.F is used to
2301         change the data as it's read in. This way, the arrays
2302         have the right units and signs at all times tha a user could
2303         possibly use them.
2304     o Corrected genmake to delete a temporary file during configuration
2305    
2306    checkpoint32
2307     o Scaling of forcing fields moved from external_forcing.F to
2308       external_fields_scale.F, called directly after loading fields.
2309     o Surface relaxation terms added to surface tendency fields in
2310       extra subroutine.
2311     o impldiff.F changed to avoid storing by TAMC of huge intermediate
2312       fields.
2313     o Changes in GMRedi to comply with packaging structure.

2317    checkpoint31
2318     o Packages interface brought in line with defined standard
2319       -> new routines packages_...F
2320       -> changes in initialise_fixed.F, initialise_varia.F
2321       -> enables initialisation interface for ECCO package
2322     o Rescaling of external forcing fields immediately after read
2323       (removed from external_forcing.F)
2324       -> new: surface_fields_scale.F
2325       -> affects ini_foorcing.F, external_fields_load.F
2326     o Computation of surface tendencies before tendency updates.
2327       -> new: external_forcing_surf.F
2328     o Change of variable names useGMRedi, useKPP, useECCO
2329     o Further changes in dynamics.F, impldiff.F for TAMC
2330     o Tested for experiments 0, 2, 4.
2331       - not yet tested for GMRedi.
2332       - not yet tested for KPP.
2333    
2334    checkpoint30
2335     o Updates for OBCs
2336     o New experiment for test OBCs (internal_wave)

2351     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
2352       included some initialisations required for TAMC.
2353     o routine calc_isoslopes: modified sqrt computation to make it
2354       differentiable for zero argument.
2355     o routines dynamics, impldiff:
2356       included store directives and tape key computations required for TAMC.
2357     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
2358    
2359    checkpoint27
2360     o fixed calc_isoslopes() to so that cancellation of terms in tensor
2361       formulation works properly with variable resolution.
2362     o restructured the calling tree between the_model_main() and dynamics()
2363     o split initialise() into initialise_fixed() and initialise_varia()

2365       in new routine ini_psurf()
2366    
2367    checkpoint26
2368     o moved some #ifdef in optional routines to encompass everything
2369       except the argument declarations. This was using up some memory.
2370     o fixed macros like _ADT to work with both versions of Linux cpp
2371     o cleaned up some unused and uninitialized variables
2372       (helps when debugging with strict compile options)
2373     o split up CPP_EEOPTIONS.h into options and macros
2374       (macros are now in eesupp/inc/CPP_EEMACROS.h)
2375     o patch for 2 processor JAM mode
2376    
2377    checkpoint25
2378     o updates for OBCs and NH
2379     o dramatically reduced memory usage
2380     o added "JAM" routines for use on Artic network
2381     o parameterization of convection by implicit vertical diffusion
2382     o added a diagnostic of convective index
2383     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
2384       (this is was partly for OBCs and NH but also in anticipation of
2385        an explicit free-surface option)
2386     o initial state input files for U and V
2387    
2388    checkpoint24
2389     o Removed some spurious "REAL"s
2390     o Updated KPP to latest version from JPL
2391     o Added a COS(latitude) in horizontal viscosity
2392    
2393    checkpoint23
2394     o Added del^4 diffusion for salt and temperature
2395     o Multiple minor fixes (implicit none's, arguments to global_sum, etc.)
2396    
2397    checkpoint22
2398     o Made many small changes: implicit none, format(i5), etc...
2399     o Introduced KPP mixing scheme (compiles and runs but *not* tested)
2400    
2401    checkpoint21
2402     o Introduced new I/O package that supports direct-access records (mdsio.F)
2403     o Split-up mid-level I/O routines
2404     o Updated input data for experiments 0,1,2,4 and 5
2405     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
2406    
2407    checkpoint20
2408     o Tidied up open-boundaries some more
2409     o Added non-hydrostatic code
2410     o Fixed some input data
2411     o Modified MPI start-up to work in "coupled" context.
2412    
2413    checkpoint19
2414     o Tidied up directory structure for verification experiments.
2415     o Added new code for open boundaries.
2416     o Corrected advective terms near boundaries.
2417     o Added CPP flag for "old UV" geometry and corrected spherical geometry.
2418     o Implemented free-slip/no-slip BCs and del^4 dissipation.
2419     o Split default parameters out of ini_parms.F into set_defaults.F.
2420    
2421    checkpoint18
2422     o Further changes for optional code generation with
2423       CPP - ugh!
2424    
2425    checkpoint17
2426     o Beginning to incorporating modularity
2427       for supporting atmos. and ocean configs.
2428     o Small changes for TAMC complinace
2429     o New ultra simple test case. Barotropic box
2430       configuration "exp0".
2431    
2432    checkpoint16
2433     o Minor changes to exchange routines to support
2434       accumulation in reverse mode. Adjoint of an
2435       assignment is an addition.
2436     o Changes to support compilation by TAMC (LR(1)
2437       syntax) and by g77 under Linux ( 72 character
2438       limit ).
2439    
2440  checkpoint15  checkpoint15
2441   Rewrote exchange routines to allow   Rewrote exchange routines to allow
