5      ==============================      ==============================
6    
7    checkpoint57x_post
8    o fix testreport Pb in multiple test experiment.
9    o cleanup our namelist syntax in verification:
10      - make it more F95 standards compliant (some work still needed)
11      - allows the vast majority of our tests to work with gfortran
12    o Non-Hydrostatic:
13     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
14     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
15    o Allow to apply AB on T,S rather than on AB(gT,gS):
16     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
17     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
18       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
19     - need a "clever" read_pickup to restart from the other AB formulation
20    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
21    o remove some unused variables (reduces number of compiler warnings)
22    o adjoint
23      * Disable useVariableViscosity for adjoint for time being
24        (there are a number of extensive recomputations)
25      * Initialize certain variables needed for adjoint
26    
27    checkpoint57w_post
28    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
29                 fix the singleCpuIO RS version of MDSWRITEFIELD
30       and add a WARNING if using globalFiles=T with multi-processors.
31    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
32      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
33    o tracer advection scheme:
34      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
35       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
36       was not very convenient).
37      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
38       (further tests needed for the implicit DST & Flux-Limiter schemes).
39    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
40      and sRef for convenience, handy, when you want to initialize
41      ptracers in a large domain with a constant non-zero value. Also,
42      untangle ptracers_init.F a little.
43    
44    checkpoint57v_post
45    o change dome exp. to use variable viscosity in side-drag terms.
46    o remove all the files from the cfc_offline test since they are now
47      incorporated into tutorial_cfc_offline which has been producing
48      identical results for a few days of testing
49    o add new parameter: sideDragFactor to enable half-slip-side BC
50      and change side-drag S/R to use viscosity from mom_calc_visc
51      (can switch back by setting sideDragFactor=0.); affects results at
52      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
53       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
54    o vorticity & strain are now computed without masking, to account for
55      no-slip-side BC in variable viscosity calculation ; mask is applied
56      anyway later on, before computing advection/coriolis terms.
57    o modify exp4 to test new obcs support for reading from external files
58      and for passive tracers
59    o fix behavior of ptracers_monitor when monitor output is written to a
60      netcdf-file; still not independent of monitor.F (writes in the same
61      file).
62    o change default value of tRef (put a uniform, meaningful value for ocean
63      & atmos) and initialize sRef (was missing, as Martin mentioned).
64    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
65      to be proportional to enstrophy dissipation length.  Thus,
66       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
67      This is now consistent with Smagorinsky and with the manual.
68    
69    checkpoint57u_post
70    o OBCS and PTRACERS: add open boundary support for passive tracers
71      - either use homogenous (pseudo) v.Neumann conditions or prescribe
72        OB-values from file; this is not different from the way theta and salinity
73        are treated
74      - however, Orlanski-radiation conditions are not supported, and the model
75        will stop if you use pTracers and Orlanski at the same time.
76      - beefed up the rountine obcs_external_fields_load: now only those open
77        boundary values are overwritten with values from files for which there
78        are really files, otherwise the OB-fields remain untouched. This makes
79        it possible to use different OBs at different ends of the domain (as
80        with EXF)
81    o reduce number of exch calls in shap_filt (s2).
82    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
83      truncation level) 4/5 MLAdjust test results (11&12 digits match).
84    
85    checkpoint57t_post
86    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
87    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
88      same truncation, independent of the face number: affects affects several
89      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
90    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
91      note that biharmonic viscosity + no-slip was not tested in any experiment.
92    o fix bug in non-linear free-surf side-drag ; generate new output for
93      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
94    o make mnc honor the writeBinaryPrec flag for most kinds of output
95    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
96    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
97      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
98    o add brackets in multi-terms sum to get same truncation, independent of
99      the face number (manage to get exactly same value of gU,gV at the cs-edge)
100      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
101    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
102      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
103      a maximum grid-scale Reynolds number.  Also, changes all length calculations
104      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
105      Suggested values of viscosity parameters found in mom_calc_visc.
106      Many new viscosity diagnostics available.
107    
108    checkpoint57s_post
109    o Add clearing-house for viscosity calculations, mom_calc_visc and
110      correct numerous bugs in LeithD and Smagorinsky discretizations.  
111      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
112      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
113      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
114      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
115      The Strain-Tension form is now called with useStrainTensonVisc=.true.
116      ViscAhStrain and viscAhTension are now retired.
117    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
118    o In response to JMC's bug report, genmake2 now ignores any soft-links
119      that it finds in the *current* directory when searching for files.
120      Soft-links found in any other source directories will still work as
121      they did before.
122    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
123      a C routine to unlimit the stack size
124    o mnc-ify pkg/aim snapshot vars
125    o mnc-ify pkg/land as requested by Daniel
126    o various changes to mnc including:
127      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
128      - output can now be grouped so that all files within a group
129          change the ITER portion of their names in lock-step together
130      - can now read ("global") PER-FACE (in addition to PER-TILE) files
131          and works with both EXCH1 and EXCH2 (but needs more testing)
132      - writing works for all verification test cases w/ g77 on Linux
133    
134    checkpoint57r_post
135    o make MNC variable initialization happen earlier
136    o add diagnostics for (almost) each term of the momentum Eq.
137    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
138    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
139    o remove MINIMAL_TAVE_OUTPUT option ;
140      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
141    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
142      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
143    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
144    o add time-dependent SST, SSS control
145    o cost terms in ecco/ modularized (new cost_generic.F)
146    o cost_averages routines are modularized (new cost_averagesgeneric.F)
147    o new infrastructure for seaice model vs. obs misfits in seaice/
148      * driver from the_main_loop.F is seaice_cost_driver.F
149      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
150      * gradient check in Exp. 6a of natl_box_adjoint/
151    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
152      (see README file)
153    
154    checkpoint57q_post
155    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
156    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
157      - bug was reported by Jean-Michel and Ian Fenty
158    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
159      update exp. cpl_aim+ocn output.
160    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
161      Needed for high-res. runs with large global files
162      to be able to limit tapelev size
163    o Changed some tests for adjoint:
164      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
165      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
166      * global_ocean.90x40x15/ back to default 3-level checkpointing
167    o Modifications to enable scripted COMMON to MODULE conversion
168      * verification/OpenAD/code/ has necessary scripts and description;
169      * converts, compiles and runs successfully;
170    
171    checkpoint57p_post
172    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
173    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
174      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
175    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
176    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
177      (was already the case for dissipation with mom_vecinv,
178       and also the case for grad.PhiHyd when staggered-timeStep)
179      This will allow to put dissipation out-off the AB time-stepping.
180     Unfortunately, affects truncation error. Update output of exp. that "fails"
181      (cg2d matching number) and leave the others for later: front_relax(10),
182      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
183      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
184    
185    checkpoint57o_post
186    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
187      (2) its ready to be documented during the 20050801 DocFest
188    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
189      for ideal_2D_oce and lab_sea on linux_ia32_g77
190    o set to #undef CTRL_SET_OLD_MAXCVARS_30
191      in global1x1_tot/code_seaice_adj to access indices 32, 33
192      (worth another tag)
193    
194    checkpoint57n_post
195    o adding precip control xx_precip 32
196    o adding swflux control xx_swflux 33
197    o Replacing 10 forcing penalty cost routines by 1 generic.
198    o Implementing partitioning in time-mean and variable adjustment
199      for atmos. state.
200    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
201    o in natl_box_adjoint:
202      * updated exp 1 to 10
203        (but does not have time-mean vs. variable split results yet)
204    o updated global1x1/*_seaice_adj/
205      to incorporate latest changes
206    o enable useSingleCpuIO for mdsio vector routines
207      (applies in particular to tapelev I/O)
208    o removed inefficient K-loop in all active_file*control*.F
209    
210    checkpoint57m_post
211    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
212      and advect_cs (use EXCH-2 and standard cs-32 grid files).
213    o pkg/exch2: filling of face-corner halo regions is optional
214      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
215    
216    checkpoint57l_post
217     tag before updating tutorials (pre-release-2)
218    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
219       for output and interpolation of input fields onto model grid)
220    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
221       Affects results of exp. rotating_tank ; update output.txt.
222    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
223          and taking the square quantity and/or using a fraction-weight field.
224    o fix aim_diagnostics_init.F mate numbers.
225    o add mnc output capability to diagnostics/diagstat and update
226      our cvsignore files for the ACSII output generated
227    
228    checkpoint57k_post
229    o lab_sea now uses diagnostics package and provides a suite of
230      new EXF diagnostics output.
231    
232    checkpoint57j_post
233    o exf
234      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
235        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
236        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
237      * extended diagnostics output
238        - now includes all EXF variables
239        - hs, hl moved to common block
240        - separate S/R for diagnostics, called after ctrl vector is added
241        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
242        - EXFqnet contains true Qnet (i.e. includes qsw)
243      * updated verif. lab_sea, global_with_exf
244      * Rearranging hflux (exf_mapfields -> exf_getforcing)
245        to ensure that diagnostics sees a true EXFqnet
246    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
247    o diagnostics pkg: change pointers so that 1 diagnostic can be used
248      several times with different frequencies.
249    o mnc-ify the thsice package as requested by Daniel Enderton
250      - the monitor--MNC output needs work
251      - many attributes need to be added (most are currently blank)
252    o mnc-ify theaim_v23 package as requested by Daniel Enderton
253      - many attributes need to be added (most are currently blank)
254    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
255    o add Sadourny like discretization to the 4th.O vorticity advection scheme
256    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
257      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
258         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
259    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
260     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
261    
262    checkpoint57i_post
263    o Diagnostics package was changed: diagnostic allocation is now deactivated
264      by setting an empty file name in the namelist (used to be by setting 0 frequency)
265    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
266      add 1rst Order upwind vertical Shear.
267    o add a quick fix for A/B checkpointing in OFFLINE mode
268    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
269      end-run around the C/Fortran linking horror in eesup/src/timers.F
270    o added pkg/runclock: allows user to terminate run based on wall clock
271    o added non-hydrostatic scaling parameter: nh_am2
272    o pkg/my82: futile attempt to make results compiler-independent by adding
273      some "_d 0", etc. no effect.
274    o for mnc output, fill the 'T' coordinate var with myTime and create a
275      separate 'iter' variable for iteration count
276    o pkg/diagnostics:
277      add new capability: output of Global/Regional & per-level statistics ;
278      tested against monitor output (including land & thSIce) on various exp.
279    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
280    
281    checkpoint57h_done
282      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
283      data.diagnostics, data.gchem, data.ptracers) is done.
284    
285    o pkg/diagnostics: prepare for Global/Regional statistics.
286      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
287    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
288      and rename it: DIFFERENT_MULTIPLE
289    
290    checkpoint57h_post
291    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
292    o pkg/diagnostics: change output frequency, now in seconds (instead
293      of Nb of iterations). This requires to change data.diagnostics.
294    checkpoint57h_pre
295    
296    o in mnc, let the user create the output dir if both mnc_outdir_date
297      and mnc_outdir_num are false
298    o add fflags() to pkg/diagnostics which allows one to specify, on a
299      per-file basis, the file precision [default behavior is unchanged]
300    o added diagnostics to pkg/kpp, including computation of mixed layer
301      depth based on a temperature/density criterion
302    o updated verification/natl_box to test the new pkg/kpp diagnostics
303    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
304    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
305    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
306      not mnc -- this mistake was found by JMC and is now corrected
307    
308    checkpoint57g_post
309    o add Adams-Bashforth 3rd Order time stepping:
310      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
311      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
312    checkpoint57g_pre
313    
314    o make lambda[Theta,Salt]ClimRelax spatially varying
315      (default remains spatially uniform constant based on tau)
316    o added new control variables
317      * init. uVel, vVel, etanN
318      * lambda[Theta,Salt]ClimRelax
319    o separate masks used for ctrl_pack/unpack 'from write_grid' output
320      (suggested by G. Forget)
321    
322    checkpoint57f_post
323    o add parameter "baseTime" = model base time = time at iteration zero
324      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
325      account for baseTime shift
326    o move Coriolis arrays from PARAMS.h to GRID.h
327    checkpoint57f_pre
328    
329    o mnc-ifying the seaice package
330    o introduced an alternative length scale calculation for use in the limiting
331      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
332    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
333    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
334      as well as grad(vort3).  Made it compatible with both approximate form
335      for the cubed sphere and full form of these gradients.  Added flag
336      useFullLeith to select between approximate and full form.  
337    o add "d0" in getcon.F to reduce differences between compilers/platforms
338      update output.txt of exp. fizhi-gridalt-hs
339    o change port_rand funtion to allow to set the seed.
340    o fix obscure MNC bug involving conversion between reals and integers
341      - it caused no problems with certain (eg. gcc, ifc) compilers but the
342        new version is now more standards-compliant
343    o adjoint-related modifications
344      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
345      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
346      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
347    
348    checkpoint57e_post
349    o Adding eddy stress controls a la Ferreira et al.
350    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
351    
352    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
353      update output.txt of exp. fizhi-gridalt-hs
354    o add more "Z" dimensions and associated coordinate vars to MNC
355    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
356    o parameter calendarDumps: when set, approximate months (30-31 days) and years
357      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
358      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
359      months and years.  Requires pkg/cal.
360    o diagnostics: add pickup functionality
361      - off by default for backwards compatibility
362      - current version only uses MDSIO -- MNC will be added
363    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
364    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
365    
366    checkpoint57d_post
367    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
368    o modify verification/ideal_2D_oce so that it tests the creation of mnc
369      output from the diagnostics package
370    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
371    o make genmake2 more portable by using ".$FS" instead of ".f" for more
372      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
373    o add coordinate variables to the MNC output from the diagnostics package
374    o change MNC-flags default value: true when useMNC=TRUE
375    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
376      the ability (off by default) to read the grid information using MNC
377    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
378    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
379    o do snap-shot diagnostics at the middle of the time-interval (instead of
380      at the end).
381    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
382      new test for AIM with thSIce + slab-ocean
383    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
384    o move state variable diagnostics to the beginning of the time step ;
385      (note: still needs some work specially for snap-shot diagnostics)
386      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
387    
388    checkpoint57c_post
389    o Change testing option (-ieee) to get closer agreement between g77 & ifort
390    o generate new output.txt files on faulks with g77 & the new -ieee option
391    checkpoint57c_pre
392    
393    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
394      update output.txt of exp. global_ocean.90x40x15
395    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
396      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
397    o add saltFlux(+File) forcing capability with periodicExternalForcing
398    o allow to use pkg diagnostics for GM-Redi & ThSIce output
399    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
400    o improvements for the MNC output from DIAGNOSTICS:
401      - correct handling of the unlimitied dimension
402      - all dims now have associated coordinate variables
403      - variables located at U, V, and Corner ("Z") points are now written
404        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
405        *all* data points are output
406    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
407    o added pkg/seaice/seaice_monitor.F
408    o mdsio_readfield.F can now read files visible only to master MPI process.
409    o pkg/seaice: some test code for ice-modified ocean stress
410    o exf_getffields interpolation defaults to bilinear for all scalar forcing
411      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
412      spurious negative numbers for precipitation and humidity.  Will cause
413      some small numerical differences for integrations using pkg/exf/exf_interp.F.
414    o pkg/ctrl/
415      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
416        May be enabled via doPackDiag
417      *  introduce z-scaling of
418         + gradient (doZscalePack) and
419         + control (doZscaleUnpack)
420    o pkg/mdsio/
421      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
422      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
423    
424    checkpoint57b_post
425    o simplify options in diagnostics_fill arguments (remove weird combinations)
426    o fix MNC coordinate variables so that they now contain per-face index
427      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
428      general, EXCH2 grids are only aligned to a "local" coordinate system
429    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
430    o Implement instantaneous output within pkg diagnostics:
431      setting a negative frequency in data.diagnostics produces
432     "snap-shot" output (as opposed to time-average if freq > 0)
433    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
434      NOTE: change ptracer diagnostics name: use 2 characters to work with
435            more than 9 tracers. Add also diagnostics of advect & diffus flux.
436    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
437      becomes the coordinate variable for the 'T' dimension
438    o add CF-style coordinate variables to MNC
439      - just a first cut:  numbers are meaningless on the cubesphere and
440        missing along the T axis but otherwise it works!
441    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
442    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
443    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
444      this is based directly on what the model compute, so that the content of
445      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
446    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
447    o clean up build options files for SunOS, in particular
448      - remove -traditional from xmakedepend
449      - change -xarch=v9 to -xarch=native for f77
450      - restore use of make (not gmake)
451      - add CC=gcc if using g77
452    o changes per discussion of AM, JMC, & EH3 today:
453      - move redundant "grid" variables out of "state" -- in preparation of
454        creating proper CF-style coordinate variables and in recognition
455        that any/all grid variables can be easily copied (eg. w/NCO) from
456        the grid files into any of the other NetCDF files
457      - *always* output grid variables with MDSIO (this will eventually be
458        changed)
459      - output MNC grid file if useMNC is true
460    o every instance of _END_MASTER() has been found and replaced with
461      _END_MASTER( myThid ) in order to satisfy certain picky Sun
462      preprocessors
463    o re-arrange diagnostics pkg initialisation:
464     - allow each package to extend the available diagnostics list
465     - add some checking and fix small problems (multi-threaded, ...)
466     - new S/R diagnostics_fill (replace fill_diagnostics):
467       look through the short list of active diag. (instead of the long list)
468       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
469    
470    checkpoint57a_post
471    o this set of changes restores TAMC compatibility
472      tested for global_ocean.90x40x15 adjoint on trough
473      (what a pain)
474    
475    checkpoint57a_pre
476    o some modifs in tools/build_options for sunos
477    o call ctrl_pack for ctrl at end for optimcycle=0
478    
479    checkpoint57
480    o add horizontal bi-harmonic viscosity for vertical velocity
481      - new parameter viscA4W (defaults to viscA4)
482      - affects only non-hydrostatic code
483      - to be done: no-slip lateral boundary conditions
484    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
485    o implement Implicit Vertical advection for pTracers
486    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
487      (implemented also for implicit vertical diffusion & advection)
488    o OBCS: extend application of tracer open boundary conditions
489      to a strip beyond the boundary of width Olx/Oly
490    o add call monitor to TAF set of required calls (flow directives)
491      and include in natl_box_adjoint
492    o untangle a few ifdefs related to cost, ctrl, autodiff
493      untangel a few ALLOW_ECCO_OPTIMIZATION
494    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
495      (theta2, salt2 in ecco_cost_weights)
496    
497    checkpoint56c_post
498    o OBCS as control variables
499      - update ctrl_ad_diff.list, obcs_ad_diff.list
500      - remove balance of obcs controls from default
501      - fix index bug nobcs in ctrl_init
502      - fix dummy fields filen in ctrl_pack
503      - add dummy weights for obcs
504    o lsopt: comment out fort.94 output
505    o optim:
506      - remove unnecessary header files
507      - adjusted namelists
508      - add xerbla.F to Makefile
509    o exf:
510      - multiple modifications of exf_check_range
511      - unit change in exf_init_runoff from [m/year] to [m/s]
512    o mdsio:
513      - i/o-vector change debugLevel from debLevA to debLevB
514    
515    checkpoint56b_post
516    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
517      is called from DO_THE_MODEL_IO
518      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
519      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
520      - clean up PTRACERS_WRITE_TIMEAVE a little
521    o add another verification experiment that tests both the cfc-pkg and
522      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
523      reactive tendencies treated inline with regular timestepping
524    o testreport previously did a lousy job of comparing small numbers, so
525      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
526      implemented in the little c-progam tmp_cmpnum.c which is embedded in
527      testreport.
528    o ptracers_monitor: bug fix for MPI
529    
530    checkpoint56a_post
531    o GCHEM: finish reorganizating the package
532      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
533        (introduces another 3D-array for each passive tracer, but only if
534        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
535        gchemTendency is not needed because the timestep is done separately)
536      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
537      - GCHEM is now---more or less cleanly---separate from PTRACERS
538      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
539        so clear to me how that should be done in a general way.
540    o CFC: improve formatting of output in CFC_ATMOS
541    o PTRACERS:
542      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
543        that ALL experiments with ptracers enable can be checked. This makes
544        GCHEM_MONITOR obsolete.
545      - include a runtime parameter PTRACERS_monitorFreq that defaults to
546        monitorFreq
547      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
548    o add PTRACERS (PTR0[1-5]) to testreport output
549    o exf_check_range:
550      * default changed to .TRUE.
551      * will check values for niter0 if debLevA, every timestep if debLevB
552      * STOP in exf_check_range if 'out of range'
553      * range chosen generous to allow for potential extema
554      TBD: a version with stricter range
555           permitted range would be runtime parameters
556    o GMredi:
557      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
558      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
559      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
560    o GCHEM:
561      - move call to GCHEM_FORCING_SEP, so that it is now called before
562        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
563      - introduced a useGCHEM runtime flag and applied it everywhere.
564      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
565        this flag is now only visible within GCHEM-pkg routines.
566      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
567        be replaced by a 3D array that is computed before thermodynamics; for
568        this, the tracer ID iTracer had to be included into the parameter list
569        of ptracers_forcing
570      - set up forward_step to call gchem_forcing, that will replace
571        gchem_forcing_int in ptracers_forcing
572      - cleaning up
573    o small cleaning of exch2: remove files that are also in eesupp/src
574    
575    checkpoint56
576    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
577    o mnc: cleanup "full" files--fixes out-of-memory problem
578    o ECCO-GODAE
579      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
580      * fully merged and updated from SIO code
581        windstress sign change affects
582        - exf_inscal_[u/v]stress
583        - sign of xx_tau[u/v] adjustments
584        - signs in cost_scat
585      * ctrl_get_gen: avoid update of tau[u/v] for first few days
586      * natl_box_adjoint updated and compressed
587      * 2-level checkpoint switch added
588        (tested in EXP. 1 of natl_box_adjoint)
589      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
590    o SVD
591      * first complete, non-hacked version for SVD calculations
592      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
593        performed via direct access files admtlm_vector.it????
594        (via ctrl_[un]pack)
595      * optimcycle is used for ARPACK iteration counter
596        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
597      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
598        and add linear transforms where necessary
599      * controls are initial/final SST, SSS (can be extended; need to check
600        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
601    o mdsio: filename info to both stderr, stdout
602    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
603      from sign change
604    
605    checkpoint55j_post
606    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
607      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
608    o add consistent build directories and .cvsignore files to verification
609    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
610    o make all subroutines 30 or less characters in length for certain older
611      compilers to work (a thorough search only turns up two routines in
612      pkg/ptracers)
613    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
614      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
615    
616    checkpoint55i_post
617    o change arrays for total vertical diffusivity (2.D if explicit,
618      3.D if implicit) ; each ptracer uses its own background value.
619    o added mnc/NetCDF output capability to ocn_compon_interf
620      - added bits to verification/cpl_aim+ocn so that it can run on
621        ITRDA and other clusters without the mpirun "-wd" option
622    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
623      configuration
624    o give MNC the ability to create additional files rather than
625      exceeding a specified file size limit "MNC_MAX_FILESIZE"
626      - the default is just less than 2GB which is a practical limit
627        on many systems
628    o Compute the non-local term using either KPP vertical diffusivity (=default)
629       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
630    
631    checkpoint55h_post
632    o add verification test "vermix"
633    o remove all the *_ioinc flags and replace with the single global
634      outputTypesInclusive flag
635    o allow to set a vertical profile of vertical diffusivity for T & S
636    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
637    o useMNC moved from data.mnc to data.pkg
638    
639    checkpoint55g_post
640    o Renaming carbon AD experiments to comply with testreport conventions
641    o Updating adjoint of Held-Suarez hs94.1x64x5
642    o Fixing directives for non-ECCO forward_step, after ECCO directives
643      have been fixed to avoid recomp. of do_oceanic_phys
644      Works well for global_ocean.90x40x15,
645      but recomp. issue remains for carbon
646    o Updating adjoint output for natl_box_adjoint after
647      pkg/ecco has been modified (see taga c55d_post)
648    
649    checkpoint55f_post
650    o rename to timeave_init_fixed
651    
652    checkpoint55e_post
653    o some delicate re-shuffle of store directives to avoid one
654      extra call of do_oceanic_physics
655      affects ecco_the_main_loop.F, do_oceanic_physics.F
656      checkpoint_lev1_directives.h
657    o NB: this may break global_ocean adjoint temporarily,
658      but it is clear how to fix it. Will do later, need this now.
659    
660    checkpoint55d_post
661    o ECCO specific cost function terms (up-to-date with 1x1 runs)
662    o ecco_cost_weights is modified to 1x1 runs
663    o modifs to allow observations to be read in as
664      single file or yearly files
665    o enable to read exf forcing fields as either
666      single file or yearly files (flag useExfYearlyFields)
667    checkpoint55d_pre
668    
669    o switch between 2-level and 3-level checkpointing
670    o add ability of MNC to write local and "partial" (eg. 2D slices where
671      the full 3D field is never actually stored) arrays to NetCDF files
672      with the correct (that is, the complete multi-dimensional) set of
673      array indicies
674      - used in mom_vecinv() to write the diagFreq output
675      - tested (demonstrated) in verification/aim.5l_cs
676    o further mnc-ification
677      - add verification/lab_sea to the list with mnc setups
678      - fix undefined mnc v-names in cd_code
679      - add kpp to mnc output (both snapshot and timeave)
680    o non-hydrostatic code
681      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
682        in calc_gw.F
683      - defaults to viscAh
684      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
685        friction or Leith) in non-hydrostatic mode, as long as there is
686        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
687    o pkg/cost
688      extend simple cost functions to treat time mean quantities
689      (T,U,V) via cost_accumulate_state from cost_tile
690    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
691        be 2 times larger than the minimum size the advection scheme requires.
692        now get a perfect conservation of salt in advect_cs test-exp (updated)
693    o GGL90 (Gaspar's TKE mixed layer)
694      - add horizontal diffusion of TKE, requires exchanges in
695        do_fields_blocking_exchanges, horizontal diffusivity is zero by
696        default. In OPA there is no horizontal diffusion of TKE but the
697        mixing coefficients are computed from a horizontal average of TKE of
698        6 points or so. I think that diffusion has a little more physical
699        justification.
700      - clean up ggl90_calc in the hope of reducing memory usage (this hope
701        was in vain)
702      - mask tke-variable in ggl90_init
703    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
704    o fix biharmonic diffusion on CS-grid.
705    o more obcs stuff
706      - added obcs_external_fields_load as an alternative to the EXF-pkg option
707        for reading boundary values. This routine is called from
708        obcs_prescribe_read
709      - updated obcs_check
710      - changed sponge layer relaxation parameter units for days to seconds
711      - turned off sponge layer by default
712      - changed argument list of OBCS_CALC to myTime+deltaTclock
713      - fixed about 35 bugs in obcs_external_fields_load
714    
715    checkpoint55c_post
716    o obcs stuff
717      - new runtime flags useOBCSprescribe, useOBCSbalance
718      - re-arranged obcs_calc
719      - moved exf_getobcs to obcs_prescibe_read
720        obcs_prescibe_read is called after ORLANSKI stuff
721        and independent of it (executable can contain all).
722      - updated obcs_check
723      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
724        These may be necessary only if tangential velocities are
725        prescribed at OB, not sure, needs testing.
726    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
727      which simplifies the calls and passes the ifc check-bounds test
728    
729    checkpoint55b_post
730    o add a 2D scalar, Z location, exchange_2 routine.
731    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
732      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
733      affects advect_cs results (for the wrong reason): update output.txt
734    o use a more standard discretization for biharmonic viscosity ;
735     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
736      affects results of dome set-up: update output.txt
737    o fix gad_advection.F (CubedSphere part), back to version 1.23
738    o fix bug in mom_vi_del2uv.F (CubedSphere part).
739    
740    checkpoint55a_post
741    o merged code to
742      * prescribe/read time-dependent open boundaries
743        (works in conjunction with exf, cal)
744      * sponge layer code for open boundaries
745      * each boundary N/S/E/W now has its own CPP option
746        (healthy for the adjoint)
747    
748    checkpoint55
749    o up-to-date adjoint of previous breaks
750      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
751      - global_ocean_ebm: adjoint still needs fix (TLM ok)
752      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
753      - carbon: * remove tr1-related adjoint verification
754                * add ptracer as control variable
755    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
756      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
757    
758    checkpoint54f_post
759    o in verification/carbin/ remove experiment related to
760      ALLOW_PASSIVE_TRACER (array tr1 etc)
761      code_ad/ input_ad/ results_ad
762    
763    o add two new packages
764      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
765        + subject to optimization (memory)
766      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
767        + subject to reordering (many GOTOs in the original code)
768        + so far opps is called for every (i,j) point, and then operates in
769          the vertical; one may want to reorder the scheme in order operate in
770          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
771          fields)
772    o overhaul of IO so that we now have flags for MDSIO and/or MNC
773      - all verification tests compile and run with linux_ia32_g77
774      - defaults are compatible with current input files--nothing
775        should change if you were not previously using MNC
776      - MNC output has been added in numerous places (eg. timeave)
777        but there are still a few writes not yet do-able with MNC
778        (this is in progress)
779      - flags now allow for either/or/both use of MDSIO and MNC and
780        documentation will soon follow
781      - numerous small formatting cleanups for ProTeX
782    o add version info (via BUILD_INFO.h) to MNC and stdout
783    
784    checkpoint54e_post
785    o add two new packages
786      - pp81 (Packanowski and Philander, 1981), Richardson number and
787        stratification dependent mixing
788      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
789      - these scheme operate in a similar manner as KPP (without ghat, of
790        course), however there is only one diffusivity that is used for both
791        temperature and salinity (and passive tracers)ç
792    o add offline package
793    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
794      provided by Stephanie Dutkiewicz
795    o genmake2: add ability to search for C compilers and cleanup test output
796      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
797    
798    checkpoint54d_post
799    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
800    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
801      leading to additional shift by 5 days each year of integration
802       (i.e. leading to considerable offset over the years)
803    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
804    o start with no AB and no initial filtering (staggerTimeStep):
805      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
806    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
807      (external loading & cpl import/export stay in forward_step.F)
808    o update coupling interface to work with new staggerTimeStep
809    o change MDSIO ptracers_pickup.
810    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
811    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
812    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
813    
814    checkpoint54c_post
815    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
816      this affects (truncation error) output.txt of test-exp:
817       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
818    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
819    o change Qnet to always be the net heat flux, (+upward).
820      affects (truncation error) output of natl_box exp.: updated
821    o define the max number of passive tracers in PTRACERS_SIZE.h
822    o start to test mnc routinely in exp0
823    o add sea-ice loading (sIceLoad) as a new forcing field.
824    
825    checkpoint54b_post
826    o add testreport "-j JOBS" option for parallel builds (tested and pretty
827       impressive on Altix and Opteron systems)
828    o diagnostics can now write NetCDF files through the mnc package
829    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
830    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
831    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
832      affects (truncation error) output of lab_sea & natl_box exp.: updated
833    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
834    
835    checkpoint54a_post
836    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
837    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
838    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
839    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
840      + internal_wave (shift in writing cg2d_ini_res)
841    checkpoint54a_pre
842    
843    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
844      - modified verification/lab_sea and natl_box_adjoint accordingly
845    
846    checkpoint54
847    checkpoint53g_post
848    o prepare splitting of thermodynamics: store convect.counter in common block
849    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
850      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
851    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
852    o new parameter "nShapS": allow to treat differently S from T (nShapT)
853    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
854    o restore adjointability
855    
856    checkpoint53f_post
857    o modifications that affect AIM experiment results (update output.txt):
858      - no advection of S at top interface Nr (pkg/generic_advdiff)
859      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
860    o AIM pkg:
861      - include stability function into surf.Flux derivative relative to Tsurf
862      - calculate clear-sky radiation & surface temp. change (for diagnostics)
863    
864    checkpoint53e_post
865    o merged cylindrical coord configuration
866    o added rotating_tank experiment
867    checkpoint53e_pre
868    
869    checkpoint53d_post
870    o faulks upgraded: re-generate output.txt that have changed:
871       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
872    o Added Bryan and Lewis, 1979, vertical diffusivity profile
873    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
874    o added Sadourny discretization of Coriolis
875      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
876      - re-enabled use of omega3 (useAbsVorticity)
877    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
878      vector-invariant equations
879      - note: does *NOT* yet use same variable visc. for no-slip BC's.
880    o recoded the lateral boundary conditions for non-hydrostatic w, this time
881      hopefully without new bugs
882      - still to do: biharmonic friction for non-hydrostatic w
883    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
884    o regenerated output for global_ocean_ebm (using -ieee)
885    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
886      of mom_common/
887      - simple re-arrangement of instructions within computing loop
888    checkpoint53d_pre
889    
890    checkpoint53c_post
891    o new version of coupler for AIM+thSIce and Ocean models
892     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
893     - land: change Evaporation of snow
894     - aim with thSIce: fix bug in snow-precip.
895    o changes to calc_gw.F
896     - bug fix for w^2 term near the bottom boundary
897     - (hopefully) improve the lateral slip boundary condtions for use with
898        partial/looped cells
899      - because the bug fix changes two verification experiments anyway (exp5
900        and plume on slope), change the lateral boundary condition from half slip
901        to the value of no_slip_sides
902    o ebm package wasnt quite up to the parallel task. Fixed that.
903    o Adjoint of EBM package + verification
904      * TLM OK
905      * ADM not sufficient accuracy yet (needs further testing)
906    
907    checkpoint53b_post
908    o Commiting new energy balance model to repository
909      * package is pkg/ebm
910      * verif. is verification/global_ocean_ebm
911      * references are in ebm_driver.F
912    C      * X. Wang, P. Stone and J. Marotzke, 1999:
913    C        Global thermohaline circulation. Part I:
914    C        Sensitivity to atmospheric moisture transport.
915    C        J. Climate 12(1), 71-82
916    C      * X. Wang, P. Stone and J. Marotzke, 1999:
917    C        Global thermohaline circulation. Part II:
918    C        Sensitivity with interactive transport.
919    C        J. Climate 12(1), 83-91
920    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
921    C        Destabilization of the thermohaline circulation
922    C        by atmospheric eddy transports.
923    C        J. Climate 7(12), 1870-1882
924    o Will need long integration testing.
925    checkpoint53b_pre
926    
927    o created pkg/mom_common in preparation for variable viscosity code
928    o renamed and split ini_mnc_io
929    o pkg/land: only liquid water can diffuse or run-off
930    o AIM using land: soil wetness availability account for snow
931    o added printMapIncludesZeros to EEPARMS namelist
932    
933    checkpoint53a_post
934    o restore TAMC compatiility for exf_constants.h
935      (no usage of _d in .h)
936    o Additional storing in KPP in an attempt to fix
937      TAMC problem with adjoint of KPP code.
938      (no success...)
939      Identical code works fine with TAF.
940    o Fixed verification/natl_box_adjoint experiments.
941      Initial conditions for Experiments 4 and 5 are now
942      set to "SEAICE_initialHEFF=0", which is more reasonable,
943      and hence gives results closer to that of Experiment 2.
944      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
945    
946    checkpoint53
947    o stable checkpoint with up to date adjoint
948      TLM tests only run for 1st grdchk at the moment. Its unclear if
949      this is a code problem or a problem with resetting code for g_
950      variables that is being autogenerated wrong.
951      Otherwise:
952       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
953       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
954         are both still in chaos following their security messes.
955    
956    checkpoint52n_post
957    o various build (mostly genmake2) changes including:
958      - ability to build/run more easily within Cygwin and MacOS X
959      - more complicated Makefiles with a stronger dependence on Gnu Make
960    o pkg/seaice modifications
961      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
962        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
963        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
964      - changed proxy for geostrophic velocity and updated
965        verification/lab_sea/results/* accordingly
966      - removed ADI dynamic solver from pkg/seaice
967      - replaced all occurrences of 1/CSTICE or 1/CSUICE
968        they caused a segmentation fault under certain circumstances
969      - removed unused field WATR
970    o bug fix in exf-package:
971      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
972         now reflect that.
973    o small fixes in the cal-package:
974      - set reference date to first of January for the 'model'-calendar
975      - failing of cal_CheckDate in cal_FullDate now actually results in a
976        warning
977    o small modifications in exf-package to increase flexibility:
978      - change climtempfreeze from a constant to a runtime parameter that
979        is specified in data.exf_clim (default = -1.9)
980      - introduce runtime parameter windstressmax (default = 2.0) that is
981        specified in data.exf
982    o fix in pkg/thsice:
983      - update Evap (Tsf changes) to be consistent with Latent heat flux
984      - maintain snow precipitation unchanged (even if Tsf >=0).
985     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
986    
987    checkpoint52m_post
988    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
989      this does not change any of the results, because myIter=0 in swfrac always
990      lead to jwtype=2 (the default anyway), but the call makes little sense
991      as a default
992    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
993    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
994      atmospheric model (AIM) to use it ; add a "slab ocean" component.
995    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
996    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
997    o extending useSingleCpuIO option to work with new exch2 I/O format
998      - old-style, missing-tile I/O is still accessible by defining CPP
999        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1000    o monitor package can write to NetCDF files and/or STDOUT
1001    o fix re-definition bug in MNC_GRID_INIT_ALL()
1002    o doc/api_reference added
1003      - a framework for building an API Reference Manual using all
1004        the "protex" comments embedded in the code
1005      - see pkg/generic_advdiff, pkg/mnc for examples
1006    o MNC:
1007      - make myThid the last argument for all subroutines
1008      - new default for the grid files: NO halos
1009      - add useMNC and other run-time flags
1010      - separate per-file-group handling of the unlimited dimension
1011      - early initialization of MNC w/ flags read at the eeboot stage
1012        and lookup tables set in initialize_fixed
1013      - write all MNC output to a freshly-created directory
1014    o thermodynamics sea-ice (thsice) is now tested with testreport.
1015    o test exp. advect_cs: use the standard cs32 grid ; update output.
1016    o Added functionality to grdchk:
1017      pick global i,j,k position (or nearest wet) where to perform check.
1018    
1019    checkpoint52l_post
1020    o new land formulation:
1021      a) use ground enthalpy as prognostic variable to ensure exact
1022         energy conservation.
1023      b) account for water temperature and for latent heat of freezing
1024         in all processes (rain, run-off, ground storage)
1025      c) compute surface and ground temperature implicitly.
1026    o aim_v23 modification for new land model:
1027      a) Treat separately land / ocean / sea-ice surface fluxes
1028         to allow implicit computation of land & sea-ice surface temp.
1029      b) add snow precipitation.
1030    checkpoint52l_pre
1031    
1032    o fix problem (when 1 tile is empty) in min/max monitor.
1033    o fix bug in timeAve (u,vZetatave in common block)
1034    o no restoring terms under ice for pkg/seaice
1035    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1036    o bug fix for pkg/seaice pickups
1037    o change MNC call locations and add coordinate attributes
1038    o mask vorticity at the corner ; affects global_ocean.cs output
1039    o fix ini_curvilinear_grid ; test CS experiments with mpi
1040    o aim.5l_cs: modify sea-ice fraction input file ; update output
1041    o exf: Adding simple range check routine for exf fields after read
1042    
1043    checkpoint52k_post
1044    o removed top-level directory "diags"
1045      - we migrated these functions to pkg/timeave a long time ago
1046    o fixed bug introduced in pkg/monitor
1047    o accuracy ctrlprec = 32 insuffient for gradient checks using
1048      averaged fields (I/O via cost_averages)
1049      -> use ctrl.h in active_file*.F to control I/O precision.
1050    o paramter list of CALL ADTHE_MAIN_LOOP
1051    o added initial do_the_model_io to ecco
1052    o set all ...Freq to zero after cost_final
1053      taveFreq, dumpFreq, pChkptFreq
1054    o MAIN and ECCO differentiability restored
1055    
1056    checkpoint52j_post
1057    o fix nchklev in tamc.h for global_ocean...
1058    o Bringing flow and store directives up-to-date
1059    o Really weird thing!
1060      call do_the_model_io from the_main_loop with parameters
1061      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1062      TAF places a faulty re-call of initialise_varia
1063      after cost_final call which should not be there!
1064    checkpoint52j_pre
1065    
1066    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1067      error messages
1068    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1069    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1070      debug output
1071    o modfied mdsio_writefield.F to handle non-global files under exch2
1072    o update AIM Cubed-Sphere exp (aim.5l_cs):
1073      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1074    o update AIM Equatorial Channel exp:
1075      use standard aim_v23 pkg and change the SST fields to be more realistic.
1076    o globalFile now works with exch2
1077    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1078      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1079    o limit timeave output for hi-res integrations
1080    
1081    checkpoint52i_post
1082    o removed CPP_EEOPTIONS.h from verification/*/code
1083    o updated the tiling for global_ocean_pressure
1084    checkpoint52i_pre
1085    
1086    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1087      the old pkg/aim).
1088    
1089    checkpoint52h_pre
1090    o shortened offending lines in exch2_send_rx?.template
1091    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1092    o genmake2: add build & execute test for NetCDF code
1093    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1094      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1095    o added useSingleCPUIO flag to monitor.F and mon_out.F
1096    o added temporary hack for sea-ice dynamics on the cube:
1097      metric terms are ignored and it is assumed that
1098      there is no sea-ice on cube faces 1, 2, 4, and 5.
1099    
1100    checkpoint52f_post
1101    o added exch2 cube routines to pkg/exch2
1102    o modified hs94.cs-32x32x5 to use it
1103    o added new grid files to hs94.cs-32x32x5
1104    checkpoint52f_pre
1105    
1106    checkpoint52e_post
1107    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1108      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1109    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1110      to work with implicit vertical advection and AB ;
1111    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1112    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1113     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1114    checkpoint52e_pre
1115    
1116    o fix bug in impldiff when Nr=1 or Nr=2.
1117    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1118    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1119    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1120      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1121    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1122    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1123    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1124    
1125    checkpoint52d_post
1126    o re-tiled many expts to allow comparison in multi-processor mode
1127      - updated output accordingly
1128      - changed hs94.128x64x5 to use intial T from file rather than use the
1129        random number generator
1130    o add infrastructure in model routines for fizhi and gridalt packages
1131    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1132    o changes to permit hi-res, cubed-sphere, configuration
1133      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1134      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1135      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1136        of surface winds for the cube
1137      (A verification experiment, based on global_ocean.cs32x15, but with
1138       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1139       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1140       complete with example surface forcing files and matlab scripts to look
1141       at the output and compare it with that of global_ocean.cs32x15.)
1142    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1143       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1144       to conform to the common rule.
1145    o check-in the first version of the coupler + interfaces for multi-components
1146       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1147       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1148       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1149       - ocean and atmos. share the same horizontal grid (no interpolation).
1150       - exchanges between component and coupler is done in forward_step
1151    o new verification experiment, cpl_aim+ocn:
1152       coupled ocean - AIM atmosphere on cs32 grid.
1153    
1154    checkpoint52d_pre
1155    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1156    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1157    
1158    checkpoint52c_post
1159    o Fixing OPTIONS files for use of exf:
1160      - ALLOW_ECCO not needed
1161      - ECCO_CPPOPTIONS.h should not be included from
1162        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1163        as has been the case in the past
1164      - All cal/exf related options are currently set in
1165        single header file. Should remain so until we
1166        agree on a consistent new policy.
1167    o Removed all CPP options for cal package.
1168      cal has no more CPP options.
1169    o modified STOREs in GAD_ADVECTION
1170    o corrected key comp. for passkey
1171    
1172    checkpoint52b_post
1173    o new version: "thsice" of thermodynamic sea-ice pkg:
1174     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1175     - modify fluxes but do not change theta directly;
1176     - light cleaning of bulk_force pkg (still needed with thsice).
1177     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1178       + output_thsice.txt to test thsice & bulk_force pkgs.
1179    o put back grid & coriolis monitor output.
1180    checkpoint52b_pre
1181    
1182    o call "do_the_model_io" at the beginning (=> dump initial state)
1183    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1184    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1185      (need info on NUMBER_OF_PTRACERS)
1186    o missing PTRACERS headers in some routines
1187    o default tamc.h in pkg/autodiff supposed to crash
1188      to ensure proper customization
1189    
1190    checkpoint52a_post
1191    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1192      - moved surfaceTendencyTice from pkg/seaice to main code
1193      - subroutine FREEZE_SURFACE now limits only surface temperature
1194        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1195        => new output.txt for global_ocean.cs32x15 & global_with_exf
1196      - keep the old version of FREEZE for backward compatibility;
1197        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1198      - corresponding modifs for TAF directives
1199    o added surface flux output variables to TIMEAVE_STATVARS

1203      but no warning issued by TAF
1204    
1205    checkpoint52a_pre
1206    o some bug fixes for #undef REAL4_IS_SLOW
1207    
1208    checkpoint52 = ecco_c52_e35
1209    o after testing adjoints of checkpoint51u_post
1210    
1211    checkpoint51u_post
1212    o this is the post-merge tag of the ecco-branch
1213      (needs another clean checkout and re-testing)
1214    o various natl_box_adjoint configs and results
1215      but no input fields
1216    o obcs adjoint not yet merged!
1217    o adding ECCO global 1x1 and 2x2 degree configs
1218    o updated/extended some store directives for seaice
1219    o pkg/ecco now containes ecco-specific part of cost function
1220    o top level routines the_main_loop, forward_step
1221      supersede those in model/src/
1222      previous input data.cost now in data.ecco
1223      (new namelist ecco_cost_nml)
1224    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1225    
1226    checkpoint51t_post
1227    o this is the pre-merge tag of the ecco-branch
1228    
1229    checkpoint51s_post
1230    o cleanup: removed various obsolete #define-s
1231    o pkg/grdchk
1232      - renamed 'ph-grd 3' to 'grad-res'
1233      - merged from ecco-branch
1234        (remaining bug fixes for obcs gradient checks)
1235      - additional high-precision output for testreport
1236        (grep for 'precision_grdchk_result')
1237    
1238    checkpoint51r_post
1239    o cleaned up or removed CPP_OPTIONS.h files
1240    o updated results for some of the tests to reflect the new
1241      optfiles (-ieee: -O0 instead of -O3)
1242    
1243    checkpoint51q_post
1244    o cd_code:
1245      - moved cd_scheme.F -> cd_code_scheme.F
1246      - separate read_checkpoint from cd_code_ini_vars.F
1247      - separated cd_code part from write_checkpoint
1248      - updated AD_SOURCE, generated .flow
1249      - added CD_CODE_VARS.h to the_main_loop

1253        xx_/adxx_ I/O
1254      - ctrl_pack/unpack cleaned
1255        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1256      - confined inclusion of AD_CONFIG.h to where necessary.
1257    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1258    
1259    checkpoint51p_post
1260    o create initial cd_code package
1261      - WARNING: the initialization of fields within packages
1262        is broken because INI_FIELDS (where READ_CHECKPOINT is
1263        called) is called *before* PACKAGES_INIT_VARIABLES.
1264        This seems to be backwards since
1265        1) its important to initially zero the entire field including
1266           the "halo" region
1267        2) zeroing needs to be done *before* reading pickup info
1268           and the pickup call might or might not happen in any
1269           particular run
1270      - this needs an overhaul for R2
1271    o cleanup verification/*/code/GMREDI_OPTIONS.h

1306      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1307      - subroutine FREEZE now limits only surface temperature
1308        (this means new output.txt for global_ocean.90x40x15,
1309         global_ocean.cs32x15, and global_with_exf)
1310    o added surface flux output variables to TIMEAVE_STATVARS

1480    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1481    o AIM: use true log-P extrapolation for near surface temp (= as in
1482        F.Molteni paper) ; update aim.5l_cs output.
1483    o New variable in PARM03 for more flexible pickups
1484    o somewhat cleaned package initialisation sequence for
1485      ctrl/ cost/ ecco/ in packages_... routines
1486    
1487    checkpoint50g_post

1513     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1514       nearly a copy of kpp_transport_s
1515     - there is no analogue to SurfaceTendencyS, so I have to use
1516       gPtr(of the surface layer) instead
1517    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1518    checkpoint50e_pre

1530    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1531    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1532    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1533    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1534    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1535    
1536    checkpoint50c_pre
1537    Merging from release1_p13:
1538    o bug fix for pkg/seaice dynamic solver
1539    o Added SEAICE_initialHEFF to pkg/seaice
1540    
1541    checkpoint50b_post
1542    o store u*,v* in gU,V instead of in guNm1,gvNm1
1543    o in order to put the momForcing out of the Adams-Bashforth:
1544      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1545      to timestep.F
1546    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1547    o re-generate output for highly sensitive test-exp:
1548       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1549    
1550    checkpoint50b_pre
1551    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1552    o corrected CPP option mismatch in exf_Bulk... functions for case
1553      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1554    
1555    checkpoint50a_post
1556    o Bug fix for merging between c50 and KPP.
1557      ikey was passed from thermodynamics to kpp_calc via
1558      common block rather than being recomputed in kpp_calc,
1559      in contradiction with new key itdkey.
1560      New key ikppkey created, and tamc.h headers updated.
1561    
1562    checkpoint50
1563    - 2nd step of merge with ecco-branch:
1564      merge changes in ecco-branch back into main trunk
1565    - bug fix in find_alpha
1566    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1567    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1568    - merged some sliced AD support routines
1569    
1570    checkpoint49
1571    merged from ecco-branch:
1572    o exf:
1573      - Enable initialisation of forcing fields to constant
1574        (runtime) values.
1575      - in exf_getffields.F
1576        Reduce i-/j-loop to interior domain, discarding overlaps.
1577        That also fixes wrong TAF-key computations for key_1, key_2
1578        with bulf formulae.
1579      - exf_init.F modify #ifdef for exf_init_evap
1580      - exf_getffieldrec.F, ctrl_getrec.F
1581        The following INT-usages are not safe:
1582          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1583          fldcount = int(fldsecs/fldperiod) + 1
1584        and were modified.
1585    o autodiff: checkpoint_lev...
1586      - updated storing for bulk formulae (some arrays were missing)
1587      - added state for seaice package
1588      - synchronized with main branch
1589    o DIVA:
1590      Modif.s in
1591      - the_main_loop.F
1592      - the_model_main.F
1593      and added cost_final_restore.F cost_final_store.F
1594      o With these changes, it is possible to fully separate
1595        the first forward run to compute the cost function (mdthe_main_loop)
1596        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1597        into separate model executions.
1598        This enables better tuning of DIVA to given queue sizes.
1599      o Loss of cost function value in consecutive DIVA runs is
1600        fixed by storing to 'costfinal' file.
1601      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1602        beginning/end of adjoint integration is accounted for.
1603      The current changes apply to TAF-1.4.26.
1604      TAF has one remaining bug, requiring one manual change
1605      (see MITgcm manual).
1606    o cal: synchronized between MAIN and ecco-branch
1607    
1608    checkpoint48i_post
1609    o Changes to restore differentiability of code w.r.t. previous tag
1610      (mostly adding new routines to make list and replacing
1611      pressure by totPhiHyd).
1612    o Updated and merged grdchk package
1613      - has both ADM and TLM checks
1614      - works for single- and multi-proc.
1615      - output cleaned
1616      - worked successfully for parallel DIVA
1617    o genmake:
1618      - Adding -platform=SP4
1619      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1620    o Modif. for DIVA:
1621      ctrl_unpack should not be called in intermediate DIVA interval.
1622      (similar thing would apply for active files such as
1623      tbar, sbar, psbar, which should not be reinitialised;
1624      only relevant for ecco-branch)
1625    
1626    checkpoint48h_post
1627    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1628    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1629    o Added SEAICE_initialHEFF to pkg/seaice
1630    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1631    
1632    checkpoint48g_post
1633    --- EOS:
1634    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1635      store total Potential in totPhyHyd for diagnostics & EOS.
1636    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1637    --- Pressure/geopotential gradient:
1638    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1639    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1640      ( changes results of global_ocean_pressure )
1641    o NLFS + z-coord.: add eta*Rho' contribution.
1642    o accurate phiHyd when using interface-W at the middle between 2 centers
1643     ( changes results of ideal_2D_oce )
1644    o includes r* 2nd term in potential gradient.
1645    
1646    checkpoint48f_post
1647    Merging from release1_p12:
1648    o Modifications for using pkg/exf with pkg/seaice
1649      - improved description of the various forcing configurations
1650      - added basic radiation bulk formulae to pkg/exf
1651      - units/sign fix for evap computation in exf_getffields.F
1652      - updated verification/global_with_exf/results/output.txt
1653    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1654      (SBO) core products, including oceanic mass, center-of-mass,
1655      angular, and bottom pressure (see pkg/sbo/README.sbo).
1656    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1657      to avoid negative values in shallow regions.
1658      - updated verification/natl_box/results/output.txt
1659      - updated verification/lab_sea/results/output.txt
1660    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1661    o Added useSingleCpuIO option (see PARAMS.h).
1662    o Updated useSingleCpuIO option in mdsio_writefield.F to
1663      work with multi-field files, e.g., for single-file pickup.
1664    o pkg/seaice:
1665      - bug fix in growth.F: QNET for no shortwave case
1666      - added HeffFile for specifying initial sea-ice thickness
1667      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1668    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1669      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1670    o pkg/seaice:
1671      - adjoint-friendly modifications
1672      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1673    
1674    checkpoint48e_post
1675    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1676    o dynamics: change definition of computational domain & adapt mom_fluxform
1677      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1678    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1679        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1680        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1681        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1682        inverted_barometer solid-body.cs-32x32x1
1683      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1684    
1685    checkpoint48d_post
1686    o in preparation for r*:
1687     a) use pre-computed gradient of hydrostatic potential:
1688        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1689     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1690        => affects results of glob_oce_pressure (different truncation error)  
1691      update output.txt of ideal_2D_oce & global_ocean_pressure
1692    
1693    checkpoint48d_pre
1694    o in preparation for r*:
1695      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1696      pass the 2 comp. of the grad. as arguments to momentum S/R.
1697      but for the moment, only used if it does not change the results.
1698    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1699    
1700    checkpoint48c_post
1701    Modifications in treatment of initial flux forcing controls
1702    to avoid extra storing of flux fields.
1703    
1704    checkpoint48c_pre
1705    o Added tidal_basin_2d experiment (currently 1D!)
1706    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1707    
1708    checkpoint48b_post
1709    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1710     (modification to pressure gradient not yet implemented)
1711    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1712      (for U & V) that are used for vertical advection of momentum.
1713    
1714    checkpoint48a_post
1715    o In preparation for r*, use temp. array to compute vertical transport
1716       in flux-form momentum pkg. => change results of few test-exp.
1717      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1718                        lab_sea, natl_box & plume_on_slope
1719    
1720    checkpoint48
1721    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1722    
1723    checkpoint47j_post
1724    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1725    o moved adexch from forward_step to addummy_in_stepping
1726    o added exch in ctrl_map_...
1727    o aveFreq.=0. at end of cost_final to avoid overwrite in
1728      reverse checkpointing loop
1729    o Yet more changes in gmredi:
1730      * adgmredi_calc_tensor
1731        avoiding all recomputation of gmredi_slope_limit
1732      * adgmredi_x/y/rtransport
1733        added flag for excessive storing to avoid recomp. of
1734        u/v/rtans, dTdx/y/z
1735        -> this is not really necessary and very memory-consuming
1736      * adgmredi_slope_psi:
1737        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1738      * gmredi_slope_limit
1739        re-activated full calculation of taperfct for case 'ac02'
1740    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1741    
1742    checkpoint47i_post
1743    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1744    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1745      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1746    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1747    o gmredi: fix few bugs.
1748    
1749    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1750    This will be a good checkpoint to plug into the ecco-branch.
1751    o few modif.'s to get latest version adjointed
1752      (mainly kick out code in ini_linear_phisurf)
1753    o modif's to run adjoint with exactConserv
1754    o case GM_BOLUS_ADVEC should be cleaned
1755      S/R gmredi_slope_psi should be cleaned
1756    o verification/carbon now has exactConserv=.TRUE.
1757    
1758    checkpoint47g_post
1759    o time-average AIM output: becomes independent from statvars time-average
1760      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1761    o After TAF bug fix:
1762      Tested adjoint of gmredi package.
1763      Tests were done with checkpoint47 rather than with latest
1764      checkpoint47f_post since the latter is broken for the adjoint
1765      verification/carbon/ contains both ADM and TLM gradient checks.
1766    Here they are, before they get changed/lost/stolen.
1767    Mostly modif.'s to fix numerical sensitivities.
1768    Gradient checks OK for
1769    - GM_taper_scheme:
1770      * clipping
1771      * ac02
1772      * linear
1773      * glw91
1774      * dm95
1775      * ldd97
1776    - GMREDI_OPTIONS:
1777      * GM_VISBECK_VARIABLE_K
1778      * GM_NON_UNITY_DIAGONAL
1779      * GM_EXTRA_DIAGONAL
1780      * GM_BOLUS_ADVEC
1781    in conjunction with data.gmredi parameters to be checked in
1782    in a few minutes under verification/carbon/code/
1783    
1784    checkpoint47f_post
1785    Merging from release1_p10:
1786    o modifications for using pkg/exf with pkg/seaice
1787      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1788        and SEAICE_EXTERNAL_FLUXES
1789      - pkg/exf CPP options EXF_READ_EVAP and
1790        EXF_NO_BULK_COMPUTATIONS
1791      - usage examples are Experiments 8 and 9 in
1792        verification/lab_sea/README
1793      - verification/lab_sea default experiment now uses
1794        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1795    
1796    checkpoint47e_post
1797    o created a tag prior to creating a branch
1798    
1799    checkpoint47d_post
1800    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1801      at the bottom boundary had an erroneous half slip boundary condition
1802    o added bottom drag and no slip boundary condition capabilities to
1803      oceanic pressure coordinates code
1804    o added new verification experiment global_ocean_pressure, this experiment is
1805      also described in the tutorial section of the manual
1806    checkpoint47d_pre
1807    
1808    checkpoint47c_post
1809    o Added a verification experiment for a global cubed-sphere ocean run
1810      -  verification/global_ocean.cubed32x32x30
1811      -  uses pkg/therm_seaice and pkg/bulk_forcing
1812    
1813    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1814    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1815      when using P-coordinate; only implemented for atmospheric config.
1816    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1817      NOTES: requires option NONLIN_FRSURF to be "#define".
1818    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1819    
1820    checkpoint47b_post
1821    Merging from release1_p9:
