5      ==============================      ==============================
6    
7    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
8       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
9       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
10    o pkg/diagnostics: add options and parameters for regional-statistics
11       diagnostics ; define regions by reading a region-mask from a file
12       (might add other options later)
13    o pkg/bulk_force:
14     - add option and parameters to use AIM surface-flux formulae.
15     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
16       others forcing fields (defined in PARM05, parameter file "data") are loaded
17       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
18     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
19     - use the right EXCH call for uwind,vwind (to work on CS-grid).
20     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
21       and parameters (note: calcWindStress replaces .NOT.readwindstress).
22     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
23    
24    checkpoint58
25    o add "--embed-source" option to genmake2 which, when the supporting
26      tools can be compiled (as determined by genmake2) will turn on the
27      embed_files package which then embeds the entire MITgcm source code
28      (*.[fFhc] + Makefile) used for the build within the executable
29      - requested by CNH but off by default
30      - adds a paltry <9MB to the mitgcmuv executable in most cases
31      - only writes the output when useEMBEDSRC in eedata is true
32    o clean up 3-dim. relaxation codes:
33      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
34      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
35      * Thanks to Tom Haine for testing!
36    
37    checkpoint57z_post
38    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
39      affects output (@ truncation level) of exp. plume_on_slope ; updated.
40    o fix the pickup behavior for obcs in combination with ptracers
41    o fix a bug in ptracers_external_fields_load
42    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
43      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
44    o transfered surface NH pressure to eta field (if exactConserv).
45    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
46         and update lab_sea output.txt file.
47    o completing 3-dim. relaxation code: additional term
48         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
49      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
50      * At compile time, in "EXF_OPTIONS.h" set
51          #define  ALLOW_CLIMTEMP_RELAXATION
52          #define  ALLOW_CLIMSALT_RELAXATION
53      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
54          tauThetaClimRelax3Dim = 15552000.0,
55          tauSaltClimRelax3Dim  = 15552000.0,
56      * 3 cases:
57          1) Use a constant-in-time 3-dim. field
58          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
59          3) Real-time relax. to time-evolving prescribed field
60    o Adding Laplacian-type smoothness constraint on
61      initial and boundary (forcing) controls (ic, bc)
62      * enable at compile-time via
63        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
64      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
65      * Absolute scale somewhat unclear so far
66      * no area weighting was included since no other cost term does so far
67    
68    checkpoint57y_post
69    First step for a NLFS adjoint
70    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
71    o new init. routines for calc_r_star, calc_surf_dr
72    o still need to deal with ini_masks_etc
73    o testreport seemed happy
74    checkpoint57y_pre
75    
76    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
77    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
78    o add new offset feature to offline pkg (plus minor cleanup)
79    o cfc fixes for final year of integration
80    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
81      be in GCHEM_OPTIONS).
82    
83    checkpoint57x_post
84    o fix testreport Pb in multiple test experiment.
85    o cleanup our namelist syntax in verification:
86      - make it more F95 standards compliant (some work still needed)
87      - allows the vast majority of our tests to work with gfortran
88    o Non-Hydrostatic:
89     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
90     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
91    o Allow to apply AB on T,S rather than on AB(gT,gS):
92     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
93     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
94       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
95     - need a "clever" read_pickup to restart from the other AB formulation
96    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
97    o remove some unused variables (reduces number of compiler warnings)
98    o adjoint
99      * Disable useVariableViscosity for adjoint for time being
100        (there are a number of extensive recomputations)
101      * Initialize certain variables needed for adjoint
102    
103    checkpoint57w_post
104    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
105                 fix the singleCpuIO RS version of MDSWRITEFIELD
106       and add a WARNING if using globalFiles=T with multi-processors.
107    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
108      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
109    o tracer advection scheme:
110      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
111       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
112       was not very convenient).
113      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
114       (further tests needed for the implicit DST & Flux-Limiter schemes).
115    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
116      and sRef for convenience, handy, when you want to initialize
117      ptracers in a large domain with a constant non-zero value. Also,
118      untangle ptracers_init.F a little.
119    
120    checkpoint57v_post
121    o change dome exp. to use variable viscosity in side-drag terms.
122    o remove all the files from the cfc_offline test since they are now
123      incorporated into tutorial_cfc_offline which has been producing
124      identical results for a few days of testing
125    o add new parameter: sideDragFactor to enable half-slip-side BC
126      and change side-drag S/R to use viscosity from mom_calc_visc
127      (can switch back by setting sideDragFactor=0.); affects results at
128      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
129       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
130    o vorticity & strain are now computed without masking, to account for
131      no-slip-side BC in variable viscosity calculation ; mask is applied
132      anyway later on, before computing advection/coriolis terms.
133    o modify exp4 to test new obcs support for reading from external files
134      and for passive tracers
135    o fix behavior of ptracers_monitor when monitor output is written to a
136      netcdf-file; still not independent of monitor.F (writes in the same
137      file).
138    o change default value of tRef (put a uniform, meaningful value for ocean
139      & atmos) and initialize sRef (was missing, as Martin mentioned).
140    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
141      to be proportional to enstrophy dissipation length.  Thus,
142       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
143      This is now consistent with Smagorinsky and with the manual.
144    
145    checkpoint57u_post
146    o OBCS and PTRACERS: add open boundary support for passive tracers
147      - either use homogenous (pseudo) v.Neumann conditions or prescribe
148        OB-values from file; this is not different from the way theta and salinity
149        are treated
150      - however, Orlanski-radiation conditions are not supported, and the model
151        will stop if you use pTracers and Orlanski at the same time.
152      - beefed up the rountine obcs_external_fields_load: now only those open
153        boundary values are overwritten with values from files for which there
154        are really files, otherwise the OB-fields remain untouched. This makes
155        it possible to use different OBs at different ends of the domain (as
156        with EXF)
157    o reduce number of exch calls in shap_filt (s2).
158    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
159      truncation level) 4/5 MLAdjust test results (11&12 digits match).
160    
161    checkpoint57t_post
162    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
163    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
164      same truncation, independent of the face number: affects affects several
165      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
166    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
167      note that biharmonic viscosity + no-slip was not tested in any experiment.
168    o fix bug in non-linear free-surf side-drag ; generate new output for
169      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
170    o make mnc honor the writeBinaryPrec flag for most kinds of output
171    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
172    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
173      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
174    o add brackets in multi-terms sum to get same truncation, independent of
175      the face number (manage to get exactly same value of gU,gV at the cs-edge)
176      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
177    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
178      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
179      a maximum grid-scale Reynolds number.  Also, changes all length calculations
180      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
181      Suggested values of viscosity parameters found in mom_calc_visc.
182      Many new viscosity diagnostics available.
183    
184    checkpoint57s_post
185    o Add clearing-house for viscosity calculations, mom_calc_visc and
186      correct numerous bugs in LeithD and Smagorinsky discretizations.  
187      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
188      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
189      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
190      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
191      The Strain-Tension form is now called with useStrainTensonVisc=.true.
192      ViscAhStrain and viscAhTension are now retired.
193    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
194    o In response to JMC's bug report, genmake2 now ignores any soft-links
195      that it finds in the *current* directory when searching for files.
196      Soft-links found in any other source directories will still work as
197      they did before.
198    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
199      a C routine to unlimit the stack size
200    o mnc-ify pkg/aim snapshot vars
201    o mnc-ify pkg/land as requested by Daniel
202    o various changes to mnc including:
203      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
204      - output can now be grouped so that all files within a group
205          change the ITER portion of their names in lock-step together
206      - can now read ("global") PER-FACE (in addition to PER-TILE) files
207          and works with both EXCH1 and EXCH2 (but needs more testing)
208      - writing works for all verification test cases w/ g77 on Linux
209    
210    checkpoint57r_post
211    o make MNC variable initialization happen earlier
212    o add diagnostics for (almost) each term of the momentum Eq.
213    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
214    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
215    o remove MINIMAL_TAVE_OUTPUT option ;
216      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
217    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
218      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
219    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
220    o add time-dependent SST, SSS control
221    o cost terms in ecco/ modularized (new cost_generic.F)
222    o cost_averages routines are modularized (new cost_averagesgeneric.F)
223    o new infrastructure for seaice model vs. obs misfits in seaice/
224      * driver from the_main_loop.F is seaice_cost_driver.F
225      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
226      * gradient check in Exp. 6a of natl_box_adjoint/
227    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
228      (see README file)
229    
230    checkpoint57q_post
231    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
232    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
233      - bug was reported by Jean-Michel and Ian Fenty
234    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
235      update exp. cpl_aim+ocn output.
236    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
237      Needed for high-res. runs with large global files
238      to be able to limit tapelev size
239    o Changed some tests for adjoint:
240      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
241      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
242      * global_ocean.90x40x15/ back to default 3-level checkpointing
243    o Modifications to enable scripted COMMON to MODULE conversion
244      * verification/OpenAD/code/ has necessary scripts and description;
245      * converts, compiles and runs successfully;
246    
247    checkpoint57p_post
248    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
249    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
250      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
251    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
252    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
253      (was already the case for dissipation with mom_vecinv,
254       and also the case for grad.PhiHyd when staggered-timeStep)
255      This will allow to put dissipation out-off the AB time-stepping.
256     Unfortunately, affects truncation error. Update output of exp. that "fails"
257      (cg2d matching number) and leave the others for later: front_relax(10),
258      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
259      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
260    
261    checkpoint57o_post
262    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
263      (2) its ready to be documented during the 20050801 DocFest
264    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
265      for ideal_2D_oce and lab_sea on linux_ia32_g77
266    o set to #undef CTRL_SET_OLD_MAXCVARS_30
267      in global1x1_tot/code_seaice_adj to access indices 32, 33
268      (worth another tag)
269    
270    checkpoint57n_post
271    o adding precip control xx_precip 32
272    o adding swflux control xx_swflux 33
273    o Replacing 10 forcing penalty cost routines by 1 generic.
274    o Implementing partitioning in time-mean and variable adjustment
275      for atmos. state.
276    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
277    o in natl_box_adjoint:
278      * updated exp 1 to 10
279        (but does not have time-mean vs. variable split results yet)
280    o updated global1x1/*_seaice_adj/
281      to incorporate latest changes
282    o enable useSingleCpuIO for mdsio vector routines
283      (applies in particular to tapelev I/O)
284    o removed inefficient K-loop in all active_file*control*.F
285    
286    checkpoint57m_post
287    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
288      and advect_cs (use EXCH-2 and standard cs-32 grid files).
289    o pkg/exch2: filling of face-corner halo regions is optional
290      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
291    
292    checkpoint57l_post
293     tag before updating tutorials (pre-release-2)
294    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
295       for output and interpolation of input fields onto model grid)
296    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
297       Affects results of exp. rotating_tank ; update output.txt.
298    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
299          and taking the square quantity and/or using a fraction-weight field.
300    o fix aim_diagnostics_init.F mate numbers.
301    o add mnc output capability to diagnostics/diagstat and update
302      our cvsignore files for the ACSII output generated
303    
304    checkpoint57k_post
305    o lab_sea now uses diagnostics package and provides a suite of
306      new EXF diagnostics output.
307    
308    checkpoint57j_post
309    o exf
310      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
311        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
312        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
313      * extended diagnostics output
314        - now includes all EXF variables
315        - hs, hl moved to common block
316        - separate S/R for diagnostics, called after ctrl vector is added
317        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
318        - EXFqnet contains true Qnet (i.e. includes qsw)
319      * updated verif. lab_sea, global_with_exf
320      * Rearranging hflux (exf_mapfields -> exf_getforcing)
321        to ensure that diagnostics sees a true EXFqnet
322    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
323    o diagnostics pkg: change pointers so that 1 diagnostic can be used
324      several times with different frequencies.
325    o mnc-ify the thsice package as requested by Daniel Enderton
326      - the monitor--MNC output needs work
327      - many attributes need to be added (most are currently blank)
328    o mnc-ify theaim_v23 package as requested by Daniel Enderton
329      - many attributes need to be added (most are currently blank)
330    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
331    o add Sadourny like discretization to the 4th.O vorticity advection scheme
332    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
333      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
334         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
335    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
336     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
337    
338    checkpoint57i_post
339    o Diagnostics package was changed: diagnostic allocation is now deactivated
340      by setting an empty file name in the namelist (used to be by setting 0 frequency)
341    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
342      add 1rst Order upwind vertical Shear.
343    o add a quick fix for A/B checkpointing in OFFLINE mode
344    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
345      end-run around the C/Fortran linking horror in eesup/src/timers.F
346    o added pkg/runclock: allows user to terminate run based on wall clock
347    o added non-hydrostatic scaling parameter: nh_am2
348    o pkg/my82: futile attempt to make results compiler-independent by adding
349      some "_d 0", etc. no effect.
350    o for mnc output, fill the 'T' coordinate var with myTime and create a
351      separate 'iter' variable for iteration count
352    o pkg/diagnostics:
353      add new capability: output of Global/Regional & per-level statistics ;
354      tested against monitor output (including land & thSIce) on various exp.
355    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
356    
357    checkpoint57h_done
358      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
359      data.diagnostics, data.gchem, data.ptracers) is done.
360    
361    o pkg/diagnostics: prepare for Global/Regional statistics.
362      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
363    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
364      and rename it: DIFFERENT_MULTIPLE
365    
366    checkpoint57h_post
367    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
368    o pkg/diagnostics: change output frequency, now in seconds (instead
369      of Nb of iterations). This requires to change data.diagnostics.
370    checkpoint57h_pre
371    
372    o in mnc, let the user create the output dir if both mnc_outdir_date
373      and mnc_outdir_num are false
374    o add fflags() to pkg/diagnostics which allows one to specify, on a
375      per-file basis, the file precision [default behavior is unchanged]
376    o added diagnostics to pkg/kpp, including computation of mixed layer
377      depth based on a temperature/density criterion
378    o updated verification/natl_box to test the new pkg/kpp diagnostics
379    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
380    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
381    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
382      not mnc -- this mistake was found by JMC and is now corrected
383    
384    checkpoint57g_post
385    o add Adams-Bashforth 3rd Order time stepping:
386      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
387      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
388    checkpoint57g_pre
389    
390    o make lambda[Theta,Salt]ClimRelax spatially varying
391      (default remains spatially uniform constant based on tau)
392    o added new control variables
393      * init. uVel, vVel, etanN
394      * lambda[Theta,Salt]ClimRelax
395    o separate masks used for ctrl_pack/unpack 'from write_grid' output
396      (suggested by G. Forget)
397    
398    checkpoint57f_post
399    o add parameter "baseTime" = model base time = time at iteration zero
400      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
401      account for baseTime shift
402    o move Coriolis arrays from PARAMS.h to GRID.h
403    checkpoint57f_pre
404    
405    o mnc-ifying the seaice package
406    o introduced an alternative length scale calculation for use in the limiting
407      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
408    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
409    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
410      as well as grad(vort3).  Made it compatible with both approximate form
411      for the cubed sphere and full form of these gradients.  Added flag
412      useFullLeith to select between approximate and full form.  
413    o add "d0" in getcon.F to reduce differences between compilers/platforms
414      update output.txt of exp. fizhi-gridalt-hs
415    o change port_rand funtion to allow to set the seed.
416    o fix obscure MNC bug involving conversion between reals and integers
417      - it caused no problems with certain (eg. gcc, ifc) compilers but the
418        new version is now more standards-compliant
419    o adjoint-related modifications
420      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
421      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
422      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
423    
424    checkpoint57e_post
425    o Adding eddy stress controls a la Ferreira et al.
426    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
427    
428    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
429      update output.txt of exp. fizhi-gridalt-hs
430    o add more "Z" dimensions and associated coordinate vars to MNC
431    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
432    o parameter calendarDumps: when set, approximate months (30-31 days) and years
433      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
434      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
435      months and years.  Requires pkg/cal.
436    o diagnostics: add pickup functionality
437      - off by default for backwards compatibility
438      - current version only uses MDSIO -- MNC will be added
439    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
440    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
441    
442    checkpoint57d_post
443    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
444    o modify verification/ideal_2D_oce so that it tests the creation of mnc
445      output from the diagnostics package
446    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
447    o make genmake2 more portable by using ".$FS" instead of ".f" for more
448      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
449    o add coordinate variables to the MNC output from the diagnostics package
450    o change MNC-flags default value: true when useMNC=TRUE
451    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
452      the ability (off by default) to read the grid information using MNC
453    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
454    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
455    o do snap-shot diagnostics at the middle of the time-interval (instead of
456      at the end).
457    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
458      new test for AIM with thSIce + slab-ocean
459    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
460    o move state variable diagnostics to the beginning of the time step ;
461      (note: still needs some work specially for snap-shot diagnostics)
462      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
463    
464    checkpoint57c_post
465    o Change testing option (-ieee) to get closer agreement between g77 & ifort
466    o generate new output.txt files on faulks with g77 & the new -ieee option
467    checkpoint57c_pre
468    
469    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
470      update output.txt of exp. global_ocean.90x40x15
471    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
472      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
473    o add saltFlux(+File) forcing capability with periodicExternalForcing
474    o allow to use pkg diagnostics for GM-Redi & ThSIce output
475    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
476    o improvements for the MNC output from DIAGNOSTICS:
477      - correct handling of the unlimitied dimension
478      - all dims now have associated coordinate variables
479      - variables located at U, V, and Corner ("Z") points are now written
480        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
481        *all* data points are output
482    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
483    o added pkg/seaice/seaice_monitor.F
484    o mdsio_readfield.F can now read files visible only to master MPI process.
485    o pkg/seaice: some test code for ice-modified ocean stress
486    o exf_getffields interpolation defaults to bilinear for all scalar forcing
487      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
488      spurious negative numbers for precipitation and humidity.  Will cause
489      some small numerical differences for integrations using pkg/exf/exf_interp.F.
490    o pkg/ctrl/
491      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
492        May be enabled via doPackDiag
493      *  introduce z-scaling of
494         + gradient (doZscalePack) and
495         + control (doZscaleUnpack)
496    o pkg/mdsio/
497      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
498      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
499    
500    checkpoint57b_post
501    o simplify options in diagnostics_fill arguments (remove weird combinations)
502    o fix MNC coordinate variables so that they now contain per-face index
503      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
504      general, EXCH2 grids are only aligned to a "local" coordinate system
505    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
506    o Implement instantaneous output within pkg diagnostics:
507      setting a negative frequency in data.diagnostics produces
508     "snap-shot" output (as opposed to time-average if freq > 0)
509    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
510      NOTE: change ptracer diagnostics name: use 2 characters to work with
511            more than 9 tracers. Add also diagnostics of advect & diffus flux.
512    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
513      becomes the coordinate variable for the 'T' dimension
514    o add CF-style coordinate variables to MNC
515      - just a first cut:  numbers are meaningless on the cubesphere and
516        missing along the T axis but otherwise it works!
517    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
518    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
519    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
520      this is based directly on what the model compute, so that the content of
521      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
522    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
523    o clean up build options files for SunOS, in particular
524      - remove -traditional from xmakedepend
525      - change -xarch=v9 to -xarch=native for f77
526      - restore use of make (not gmake)
527      - add CC=gcc if using g77
528    o changes per discussion of AM, JMC, & EH3 today:
529      - move redundant "grid" variables out of "state" -- in preparation of
530        creating proper CF-style coordinate variables and in recognition
531        that any/all grid variables can be easily copied (eg. w/NCO) from
532        the grid files into any of the other NetCDF files
533      - *always* output grid variables with MDSIO (this will eventually be
534        changed)
535      - output MNC grid file if useMNC is true
536    o every instance of _END_MASTER() has been found and replaced with
537      _END_MASTER( myThid ) in order to satisfy certain picky Sun
538      preprocessors
539    o re-arrange diagnostics pkg initialisation:
540     - allow each package to extend the available diagnostics list
541     - add some checking and fix small problems (multi-threaded, ...)
542     - new S/R diagnostics_fill (replace fill_diagnostics):
543       look through the short list of active diag. (instead of the long list)
544       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
545    
546    checkpoint57a_post
547    o this set of changes restores TAMC compatibility
548      tested for global_ocean.90x40x15 adjoint on trough
549      (what a pain)
550    
551    checkpoint57a_pre
552    o some modifs in tools/build_options for sunos
553    o call ctrl_pack for ctrl at end for optimcycle=0
554    
555    checkpoint57
556    o add horizontal bi-harmonic viscosity for vertical velocity
557      - new parameter viscA4W (defaults to viscA4)
558      - affects only non-hydrostatic code
559      - to be done: no-slip lateral boundary conditions
560    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
561    o implement Implicit Vertical advection for pTracers
562    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
563      (implemented also for implicit vertical diffusion & advection)
564    o OBCS: extend application of tracer open boundary conditions
565      to a strip beyond the boundary of width Olx/Oly
566    o add call monitor to TAF set of required calls (flow directives)
567      and include in natl_box_adjoint
568    o untangle a few ifdefs related to cost, ctrl, autodiff
569      untangel a few ALLOW_ECCO_OPTIMIZATION
570    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
571      (theta2, salt2 in ecco_cost_weights)
572    
573    checkpoint56c_post
574    o OBCS as control variables
575      - update ctrl_ad_diff.list, obcs_ad_diff.list
576      - remove balance of obcs controls from default
577      - fix index bug nobcs in ctrl_init
578      - fix dummy fields filen in ctrl_pack
579      - add dummy weights for obcs
580    o lsopt: comment out fort.94 output
581    o optim:
582      - remove unnecessary header files
583      - adjusted namelists
584      - add xerbla.F to Makefile
585    o exf:
586      - multiple modifications of exf_check_range
587      - unit change in exf_init_runoff from [m/year] to [m/s]
588    o mdsio:
589      - i/o-vector change debugLevel from debLevA to debLevB
590    
591    checkpoint56b_post
592    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
593      is called from DO_THE_MODEL_IO
594      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
595      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
596      - clean up PTRACERS_WRITE_TIMEAVE a little
597    o add another verification experiment that tests both the cfc-pkg and
598      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
599      reactive tendencies treated inline with regular timestepping
600    o testreport previously did a lousy job of comparing small numbers, so
601      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
602      implemented in the little c-progam tmp_cmpnum.c which is embedded in
603      testreport.
604    o ptracers_monitor: bug fix for MPI
605    
606    checkpoint56a_post
607    o GCHEM: finish reorganizating the package
608      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
609        (introduces another 3D-array for each passive tracer, but only if
610        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
611        gchemTendency is not needed because the timestep is done separately)
612      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
613      - GCHEM is now---more or less cleanly---separate from PTRACERS
614      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
615        so clear to me how that should be done in a general way.
616    o CFC: improve formatting of output in CFC_ATMOS
617    o PTRACERS:
618      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
619        that ALL experiments with ptracers enable can be checked. This makes
620        GCHEM_MONITOR obsolete.
621      - include a runtime parameter PTRACERS_monitorFreq that defaults to
622        monitorFreq
623      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
624    o add PTRACERS (PTR0[1-5]) to testreport output
625    o exf_check_range:
626      * default changed to .TRUE.
627      * will check values for niter0 if debLevA, every timestep if debLevB
628      * STOP in exf_check_range if 'out of range'
629      * range chosen generous to allow for potential extema
630      TBD: a version with stricter range
631           permitted range would be runtime parameters
632    o GMredi:
633      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
634      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
635      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
636    o GCHEM:
637      - move call to GCHEM_FORCING_SEP, so that it is now called before
638        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
639      - introduced a useGCHEM runtime flag and applied it everywhere.
640      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
641        this flag is now only visible within GCHEM-pkg routines.
642      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
643        be replaced by a 3D array that is computed before thermodynamics; for
644        this, the tracer ID iTracer had to be included into the parameter list
645        of ptracers_forcing
646      - set up forward_step to call gchem_forcing, that will replace
647        gchem_forcing_int in ptracers_forcing
648      - cleaning up
649    o small cleaning of exch2: remove files that are also in eesupp/src
650    
651    checkpoint56
652    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
653    o mnc: cleanup "full" files--fixes out-of-memory problem
654    o ECCO-GODAE
655      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
656      * fully merged and updated from SIO code
657        windstress sign change affects
658        - exf_inscal_[u/v]stress
659        - sign of xx_tau[u/v] adjustments
660        - signs in cost_scat
661      * ctrl_get_gen: avoid update of tau[u/v] for first few days
662      * natl_box_adjoint updated and compressed
663      * 2-level checkpoint switch added
664        (tested in EXP. 1 of natl_box_adjoint)
665      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
666    o SVD
667      * first complete, non-hacked version for SVD calculations
668      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
669        performed via direct access files admtlm_vector.it????
670        (via ctrl_[un]pack)
671      * optimcycle is used for ARPACK iteration counter
672        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
673      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
674        and add linear transforms where necessary
675      * controls are initial/final SST, SSS (can be extended; need to check
676        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
677    o mdsio: filename info to both stderr, stdout
678    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
679      from sign change
680    
681    checkpoint55j_post
682    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
683      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
684    o add consistent build directories and .cvsignore files to verification
685    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
686    o make all subroutines 30 or less characters in length for certain older
687      compilers to work (a thorough search only turns up two routines in
688      pkg/ptracers)
689    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
690      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
691    
692    checkpoint55i_post
693    o change arrays for total vertical diffusivity (2.D if explicit,
694      3.D if implicit) ; each ptracer uses its own background value.
695    o added mnc/NetCDF output capability to ocn_compon_interf
696      - added bits to verification/cpl_aim+ocn so that it can run on
697        ITRDA and other clusters without the mpirun "-wd" option
698    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
699      configuration
700    o give MNC the ability to create additional files rather than
701      exceeding a specified file size limit "MNC_MAX_FILESIZE"
702      - the default is just less than 2GB which is a practical limit
703        on many systems
704    o Compute the non-local term using either KPP vertical diffusivity (=default)
705       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
706    
707    checkpoint55h_post
708    o add verification test "vermix"
709    o remove all the *_ioinc flags and replace with the single global
710      outputTypesInclusive flag
711    o allow to set a vertical profile of vertical diffusivity for T & S
712    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
713    o useMNC moved from data.mnc to data.pkg
714    
715    checkpoint55g_post
716    o Renaming carbon AD experiments to comply with testreport conventions
717    o Updating adjoint of Held-Suarez hs94.1x64x5
718    o Fixing directives for non-ECCO forward_step, after ECCO directives
719      have been fixed to avoid recomp. of do_oceanic_phys
720      Works well for global_ocean.90x40x15,
721      but recomp. issue remains for carbon
722    o Updating adjoint output for natl_box_adjoint after
723      pkg/ecco has been modified (see taga c55d_post)
724    
725    checkpoint55f_post
726    o rename to timeave_init_fixed
727    
728    checkpoint55e_post
729    o some delicate re-shuffle of store directives to avoid one
730      extra call of do_oceanic_physics
731      affects ecco_the_main_loop.F, do_oceanic_physics.F
732      checkpoint_lev1_directives.h
733    o NB: this may break global_ocean adjoint temporarily,
734      but it is clear how to fix it. Will do later, need this now.
735    
736    checkpoint55d_post
737    o ECCO specific cost function terms (up-to-date with 1x1 runs)
738    o ecco_cost_weights is modified to 1x1 runs
739    o modifs to allow observations to be read in as
740      single file or yearly files
741    o enable to read exf forcing fields as either
742      single file or yearly files (flag useExfYearlyFields)
743    checkpoint55d_pre
744    
745    o switch between 2-level and 3-level checkpointing
746    o add ability of MNC to write local and "partial" (eg. 2D slices where
747      the full 3D field is never actually stored) arrays to NetCDF files
748      with the correct (that is, the complete multi-dimensional) set of
749      array indicies
750      - used in mom_vecinv() to write the diagFreq output
751      - tested (demonstrated) in verification/aim.5l_cs
752    o further mnc-ification
753      - add verification/lab_sea to the list with mnc setups
754      - fix undefined mnc v-names in cd_code
755      - add kpp to mnc output (both snapshot and timeave)
756    o non-hydrostatic code
757      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
758        in calc_gw.F
759      - defaults to viscAh
760      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
761        friction or Leith) in non-hydrostatic mode, as long as there is
762        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
763    o pkg/cost
764      extend simple cost functions to treat time mean quantities
765      (T,U,V) via cost_accumulate_state from cost_tile
766    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
767        be 2 times larger than the minimum size the advection scheme requires.
768        now get a perfect conservation of salt in advect_cs test-exp (updated)
769    o GGL90 (Gaspar's TKE mixed layer)
770      - add horizontal diffusion of TKE, requires exchanges in
771        do_fields_blocking_exchanges, horizontal diffusivity is zero by
772        default. In OPA there is no horizontal diffusion of TKE but the
773        mixing coefficients are computed from a horizontal average of TKE of
774        6 points or so. I think that diffusion has a little more physical
775        justification.
776      - clean up ggl90_calc in the hope of reducing memory usage (this hope
777        was in vain)
778      - mask tke-variable in ggl90_init
779    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
780    o fix biharmonic diffusion on CS-grid.
781    o more obcs stuff
782      - added obcs_external_fields_load as an alternative to the EXF-pkg option
783        for reading boundary values. This routine is called from
784        obcs_prescribe_read
785      - updated obcs_check
786      - changed sponge layer relaxation parameter units for days to seconds
787      - turned off sponge layer by default
788      - changed argument list of OBCS_CALC to myTime+deltaTclock
789      - fixed about 35 bugs in obcs_external_fields_load
790    
791    checkpoint55c_post
792    o obcs stuff
793      - new runtime flags useOBCSprescribe, useOBCSbalance
794      - re-arranged obcs_calc
795      - moved exf_getobcs to obcs_prescibe_read
796        obcs_prescibe_read is called after ORLANSKI stuff
797        and independent of it (executable can contain all).
798      - updated obcs_check
799      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
800        These may be necessary only if tangential velocities are
801        prescribed at OB, not sure, needs testing.
802    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
803      which simplifies the calls and passes the ifc check-bounds test
804    
805    checkpoint55b_post
806    o add a 2D scalar, Z location, exchange_2 routine.
807    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
808      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
809      affects advect_cs results (for the wrong reason): update output.txt
810    o use a more standard discretization for biharmonic viscosity ;
811     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
812      affects results of dome set-up: update output.txt
813    o fix gad_advection.F (CubedSphere part), back to version 1.23
814    o fix bug in mom_vi_del2uv.F (CubedSphere part).
815    
816    checkpoint55a_post
817    o merged code to
818      * prescribe/read time-dependent open boundaries
819        (works in conjunction with exf, cal)
820      * sponge layer code for open boundaries
821      * each boundary N/S/E/W now has its own CPP option
822        (healthy for the adjoint)
823    
824    checkpoint55
825    o up-to-date adjoint of previous breaks
826      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
827      - global_ocean_ebm: adjoint still needs fix (TLM ok)
828      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
829      - carbon: * remove tr1-related adjoint verification
830                * add ptracer as control variable
831    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
832      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
833    
834    checkpoint54f_post
835    o in verification/carbin/ remove experiment related to
836      ALLOW_PASSIVE_TRACER (array tr1 etc)
837      code_ad/ input_ad/ results_ad
838    
839    o add two new packages
840      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
841        + subject to optimization (memory)
842      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
843        + subject to reordering (many GOTOs in the original code)
844        + so far opps is called for every (i,j) point, and then operates in
845          the vertical; one may want to reorder the scheme in order operate in
846          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
847          fields)
848    o overhaul of IO so that we now have flags for MDSIO and/or MNC
849      - all verification tests compile and run with linux_ia32_g77
850      - defaults are compatible with current input files--nothing
851        should change if you were not previously using MNC
852      - MNC output has been added in numerous places (eg. timeave)
853        but there are still a few writes not yet do-able with MNC
854        (this is in progress)
855      - flags now allow for either/or/both use of MDSIO and MNC and
856        documentation will soon follow
857      - numerous small formatting cleanups for ProTeX
858    o add version info (via BUILD_INFO.h) to MNC and stdout
859    
860    checkpoint54e_post
861    o add two new packages
862      - pp81 (Packanowski and Philander, 1981), Richardson number and
863        stratification dependent mixing
864      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
865      - these scheme operate in a similar manner as KPP (without ghat, of
866        course), however there is only one diffusivity that is used for both
867        temperature and salinity (and passive tracers)ç
868    o add offline package
869    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
870      provided by Stephanie Dutkiewicz
871    o genmake2: add ability to search for C compilers and cleanup test output
872      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
873    
874    checkpoint54d_post
875    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
876    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
877      leading to additional shift by 5 days each year of integration
878       (i.e. leading to considerable offset over the years)
879    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
880    o start with no AB and no initial filtering (staggerTimeStep):
881      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
882    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
883      (external loading & cpl import/export stay in forward_step.F)
884    o update coupling interface to work with new staggerTimeStep
885    o change MDSIO ptracers_pickup.
886    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
887    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
888    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
889    
890    checkpoint54c_post
891    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
892      this affects (truncation error) output.txt of test-exp:
893       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
894    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
895    o change Qnet to always be the net heat flux, (+upward).
896      affects (truncation error) output of natl_box exp.: updated
897    o define the max number of passive tracers in PTRACERS_SIZE.h
898    o start to test mnc routinely in exp0
899    o add sea-ice loading (sIceLoad) as a new forcing field.
900    
901    checkpoint54b_post
902    o add testreport "-j JOBS" option for parallel builds (tested and pretty
903       impressive on Altix and Opteron systems)
904    o diagnostics can now write NetCDF files through the mnc package
905    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
906    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
907    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
908      affects (truncation error) output of lab_sea & natl_box exp.: updated
909    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
910    
911    checkpoint54a_post
912    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
913    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
914    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
915    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
916      + internal_wave (shift in writing cg2d_ini_res)
917    checkpoint54a_pre
918    
919    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
920      - modified verification/lab_sea and natl_box_adjoint accordingly
921    
922    checkpoint54
923    checkpoint53g_post
924    o prepare splitting of thermodynamics: store convect.counter in common block
925    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
926      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
927    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
928    o new parameter "nShapS": allow to treat differently S from T (nShapT)
929    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
930    o restore adjointability
931    
932    checkpoint53f_post
933    o modifications that affect AIM experiment results (update output.txt):
934      - no advection of S at top interface Nr (pkg/generic_advdiff)
935      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
936    o AIM pkg:
937      - include stability function into surf.Flux derivative relative to Tsurf
938      - calculate clear-sky radiation & surface temp. change (for diagnostics)
939    
940    checkpoint53e_post
941    o merged cylindrical coord configuration
942    o added rotating_tank experiment
943    checkpoint53e_pre
944    
945    checkpoint53d_post
946    o faulks upgraded: re-generate output.txt that have changed:
947       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
948    o Added Bryan and Lewis, 1979, vertical diffusivity profile
949    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
950    o added Sadourny discretization of Coriolis
951      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
952      - re-enabled use of omega3 (useAbsVorticity)
953    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
954      vector-invariant equations
955      - note: does *NOT* yet use same variable visc. for no-slip BC's.
956    o recoded the lateral boundary conditions for non-hydrostatic w, this time
957      hopefully without new bugs
958      - still to do: biharmonic friction for non-hydrostatic w
959    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
960    o regenerated output for global_ocean_ebm (using -ieee)
961    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
962      of mom_common/
963      - simple re-arrangement of instructions within computing loop
964    checkpoint53d_pre
965    
966    checkpoint53c_post
967    o new version of coupler for AIM+thSIce and Ocean models
968     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
969     - land: change Evaporation of snow
970     - aim with thSIce: fix bug in snow-precip.
971    o changes to calc_gw.F
972     - bug fix for w^2 term near the bottom boundary
973     - (hopefully) improve the lateral slip boundary condtions for use with
974        partial/looped cells
975      - because the bug fix changes two verification experiments anyway (exp5
976        and plume on slope), change the lateral boundary condition from half slip
977        to the value of no_slip_sides
978    o ebm package wasnt quite up to the parallel task. Fixed that.
979    o Adjoint of EBM package + verification
980      * TLM OK
981      * ADM not sufficient accuracy yet (needs further testing)
982    
983    checkpoint53b_post
984    o Commiting new energy balance model to repository
985      * package is pkg/ebm
986      * verif. is verification/global_ocean_ebm
987      * references are in ebm_driver.F
988    C      * X. Wang, P. Stone and J. Marotzke, 1999:
989    C        Global thermohaline circulation. Part I:
990    C        Sensitivity to atmospheric moisture transport.
991    C        J. Climate 12(1), 71-82
992    C      * X. Wang, P. Stone and J. Marotzke, 1999:
993    C        Global thermohaline circulation. Part II:
994    C        Sensitivity with interactive transport.
995    C        J. Climate 12(1), 83-91
996    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
997    C        Destabilization of the thermohaline circulation
998    C        by atmospheric eddy transports.
999    C        J. Climate 7(12), 1870-1882
1000    o Will need long integration testing.
1001    checkpoint53b_pre
1002    
1003    o created pkg/mom_common in preparation for variable viscosity code
1004    o renamed and split ini_mnc_io
1005    o pkg/land: only liquid water can diffuse or run-off
1006    o AIM using land: soil wetness availability account for snow
1007    o added printMapIncludesZeros to EEPARMS namelist
1008    
1009    checkpoint53a_post
1010    o restore TAMC compatiility for exf_constants.h
1011      (no usage of _d in .h)
1012    o Additional storing in KPP in an attempt to fix
1013      TAMC problem with adjoint of KPP code.
1014      (no success...)
1015      Identical code works fine with TAF.
1016    o Fixed verification/natl_box_adjoint experiments.
1017      Initial conditions for Experiments 4 and 5 are now
1018      set to "SEAICE_initialHEFF=0", which is more reasonable,
1019      and hence gives results closer to that of Experiment 2.
1020      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1021    
1022    checkpoint53
1023    o stable checkpoint with up to date adjoint
1024      TLM tests only run for 1st grdchk at the moment. Its unclear if
1025      this is a code problem or a problem with resetting code for g_
1026      variables that is being autogenerated wrong.
1027      Otherwise:
1028       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1029       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1030         are both still in chaos following their security messes.
1031    
1032    checkpoint52n_post
1033    o various build (mostly genmake2) changes including:
1034      - ability to build/run more easily within Cygwin and MacOS X
1035      - more complicated Makefiles with a stronger dependence on Gnu Make
1036    o pkg/seaice modifications
1037      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1038        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1039        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1040      - changed proxy for geostrophic velocity and updated
1041        verification/lab_sea/results/* accordingly
1042      - removed ADI dynamic solver from pkg/seaice
1043      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1044        they caused a segmentation fault under certain circumstances
1045      - removed unused field WATR
1046    o bug fix in exf-package:
1047      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1048         now reflect that.
1049    o small fixes in the cal-package:
1050      - set reference date to first of January for the 'model'-calendar
1051      - failing of cal_CheckDate in cal_FullDate now actually results in a
1052        warning
1053    o small modifications in exf-package to increase flexibility:
1054      - change climtempfreeze from a constant to a runtime parameter that
1055        is specified in data.exf_clim (default = -1.9)
1056      - introduce runtime parameter windstressmax (default = 2.0) that is
1057        specified in data.exf
1058    o fix in pkg/thsice:
1059      - update Evap (Tsf changes) to be consistent with Latent heat flux
1060      - maintain snow precipitation unchanged (even if Tsf >=0).
1061     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1062    
1063    checkpoint52m_post
1064    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1065      this does not change any of the results, because myIter=0 in swfrac always
1066      lead to jwtype=2 (the default anyway), but the call makes little sense
1067      as a default
1068    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1069    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1070      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1071    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1072    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1073    o extending useSingleCpuIO option to work with new exch2 I/O format
1074      - old-style, missing-tile I/O is still accessible by defining CPP
1075        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1076    o monitor package can write to NetCDF files and/or STDOUT
1077    o fix re-definition bug in MNC_GRID_INIT_ALL()
1078    o doc/api_reference added
1079      - a framework for building an API Reference Manual using all
1080        the "protex" comments embedded in the code
1081      - see pkg/generic_advdiff, pkg/mnc for examples
1082    o MNC:
1083      - make myThid the last argument for all subroutines
1084      - new default for the grid files: NO halos
1085      - add useMNC and other run-time flags
1086      - separate per-file-group handling of the unlimited dimension
1087      - early initialization of MNC w/ flags read at the eeboot stage
1088        and lookup tables set in initialize_fixed
1089      - write all MNC output to a freshly-created directory
1090    o thermodynamics sea-ice (thsice) is now tested with testreport.
1091    o test exp. advect_cs: use the standard cs32 grid ; update output.
1092    o Added functionality to grdchk:
1093      pick global i,j,k position (or nearest wet) where to perform check.
1094    
1095    checkpoint52l_post
1096    o new land formulation:
1097      a) use ground enthalpy as prognostic variable to ensure exact
1098         energy conservation.
1099      b) account for water temperature and for latent heat of freezing
1100         in all processes (rain, run-off, ground storage)
1101      c) compute surface and ground temperature implicitly.
1102    o aim_v23 modification for new land model:
1103      a) Treat separately land / ocean / sea-ice surface fluxes
1104         to allow implicit computation of land & sea-ice surface temp.
1105      b) add snow precipitation.
1106    checkpoint52l_pre
1107    
1108    o fix problem (when 1 tile is empty) in min/max monitor.
1109    o fix bug in timeAve (u,vZetatave in common block)
1110    o no restoring terms under ice for pkg/seaice
1111    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1112    o bug fix for pkg/seaice pickups
1113    o change MNC call locations and add coordinate attributes
1114    o mask vorticity at the corner ; affects global_ocean.cs output
1115    o fix ini_curvilinear_grid ; test CS experiments with mpi
1116    o aim.5l_cs: modify sea-ice fraction input file ; update output
1117    o exf: Adding simple range check routine for exf fields after read
1118    
1119    checkpoint52k_post
1120    o removed top-level directory "diags"
1121      - we migrated these functions to pkg/timeave a long time ago
1122    o fixed bug introduced in pkg/monitor
1123    o accuracy ctrlprec = 32 insuffient for gradient checks using
1124      averaged fields (I/O via cost_averages)
1125      -> use ctrl.h in active_file*.F to control I/O precision.
1126    o paramter list of CALL ADTHE_MAIN_LOOP
1127    o added initial do_the_model_io to ecco
1128    o set all ...Freq to zero after cost_final

1130    o MAIN and ECCO differentiability restored
1131    
1132    checkpoint52j_post
1133    o fix nchklev in tamc.h for global_ocean...
1134    o Bringing flow and store directives up-to-date
1135    o Really weird thing!
1136      call do_the_model_io from the_main_loop with parameters
1137      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1138      TAF places a faulty re-call of initialise_varia
1139      after cost_final call which should not be there!
1140    checkpoint52j_pre
1141    
1142    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1143      error messages
1144    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1145    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1146      debug output
1147    o modfied mdsio_writefield.F to handle non-global files under exch2
1148    o update AIM Cubed-Sphere exp (aim.5l_cs):
1149      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1150    o update AIM Equatorial Channel exp:
1151      use standard aim_v23 pkg and change the SST fields to be more realistic.
1152    o globalFile now works with exch2
1153    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1154      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1155    o limit timeave output for hi-res integrations
1156    
1157    checkpoint52i_post

1160    checkpoint52i_pre
1161    
1162    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1163      the old pkg/aim).
1164    
1165    checkpoint52h_pre
1166    o shortened offending lines in exch2_send_rx?.template
1167    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1168    o genmake2: add build & execute test for NetCDF code
1169    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1170      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1171    o added useSingleCPUIO flag to monitor.F and mon_out.F
1172    o added temporary hack for sea-ice dynamics on the cube:
1173      metric terms are ignored and it is assumed that
1174      there is no sea-ice on cube faces 1, 2, 4, and 5.
1175    
1176    checkpoint52f_post
1177    o added exch2 cube routines to pkg/exch2
1178    o modified hs94.cs-32x32x5 to use it
1179    o added new grid files to hs94.cs-32x32x5
1180    checkpoint52f_pre
1181    
1182    checkpoint52e_post
1183    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1184      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1185    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1186      to work with implicit vertical advection and AB ;
1187    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1188    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1189     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1190    checkpoint52e_pre
1191    
1192    o fix bug in impldiff when Nr=1 or Nr=2.
1193    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1194    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1195    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1196      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1197    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1198    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1199    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1200    
1201    checkpoint52d_post
1202    o re-tiled many expts to allow comparison in multi-processor mode
1203      - updated output accordingly
1204      - changed hs94.128x64x5 to use intial T from file rather than use the
1205        random number generator
1206    o add infrastructure in model routines for fizhi and gridalt packages
1207    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1208    o changes to permit hi-res, cubed-sphere, configuration
1209      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1210      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1211      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1212        of surface winds for the cube
1213      (A verification experiment, based on global_ocean.cs32x15, but with
1214       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1215       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1216       complete with example surface forcing files and matlab scripts to look
1217       at the output and compare it with that of global_ocean.cs32x15.)
1218    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1219       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1220       to conform to the common rule.
1221    o check-in the first version of the coupler + interfaces for multi-components
1222       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1223       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1224       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1225       - ocean and atmos. share the same horizontal grid (no interpolation).
1226       - exchanges between component and coupler is done in forward_step
1227    o new verification experiment, cpl_aim+ocn:
1228       coupled ocean - AIM atmosphere on cs32 grid.
1229    
1230    checkpoint52d_pre
1231    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1232    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1233    
1234    checkpoint52c_post
1235    o Fixing OPTIONS files for use of exf:
1236      - ALLOW_ECCO not needed
1237      - ECCO_CPPOPTIONS.h should not be included from
1238        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1239        as has been the case in the past
1240      - All cal/exf related options are currently set in
1241        single header file. Should remain so until we
1242        agree on a consistent new policy.
1243    o Removed all CPP options for cal package.
1244      cal has no more CPP options.
1245    o modified STOREs in GAD_ADVECTION
1246    o corrected key comp. for passkey
1247    
1248    checkpoint52b_post
1249    o new version: "thsice" of thermodynamic sea-ice pkg:
1250     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1251     - modify fluxes but do not change theta directly;
1252     - light cleaning of bulk_force pkg (still needed with thsice).
1253     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1254       + output_thsice.txt to test thsice & bulk_force pkgs.
1255    o put back grid & coriolis monitor output.
1256    checkpoint52b_pre
1257    
1258    o call "do_the_model_io" at the beginning (=> dump initial state)
1259    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1260    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1261      (need info on NUMBER_OF_PTRACERS)
1262    o missing PTRACERS headers in some routines
1263    o default tamc.h in pkg/autodiff supposed to crash
1264      to ensure proper customization
1265    
1266    checkpoint52a_post
1267    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1268      - moved surfaceTendencyTice from pkg/seaice to main code
1269      - subroutine FREEZE_SURFACE now limits only surface temperature
1270        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1271        => new output.txt for global_ocean.cs32x15 & global_with_exf
1272      - keep the old version of FREEZE for backward compatibility;
1273        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1274      - corresponding modifs for TAF directives
1275    o added surface flux output variables to TIMEAVE_STATVARS

1279      but no warning issued by TAF
1280    
1281    checkpoint52a_pre
1282    o some bug fixes for #undef REAL4_IS_SLOW
1283    
1284    checkpoint52 = ecco_c52_e35
1285    o after testing adjoints of checkpoint51u_post
1286    
1287    checkpoint51u_post
1288    o this is the post-merge tag of the ecco-branch
1289      (needs another clean checkout and re-testing)
1290    o various natl_box_adjoint configs and results
1291      but no input fields
1292    o obcs adjoint not yet merged!
1293    o adding ECCO global 1x1 and 2x2 degree configs
1294    o updated/extended some store directives for seaice
1295    o pkg/ecco now containes ecco-specific part of cost function
1296    o top level routines the_main_loop, forward_step
1297      supersede those in model/src/
1298      previous input data.cost now in data.ecco
1299      (new namelist ecco_cost_nml)
1300    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1301    
1302    checkpoint51t_post
1303    o this is the pre-merge tag of the ecco-branch
1304    
1305    checkpoint51s_post
1306    o cleanup: removed various obsolete #define-s
1307    o pkg/grdchk
1308      - renamed 'ph-grd 3' to 'grad-res'
1309      - merged from ecco-branch
1310        (remaining bug fixes for obcs gradient checks)
1311      - additional high-precision output for testreport
1312        (grep for 'precision_grdchk_result')
1313    
1314    checkpoint51r_post
1315    o cleaned up or removed CPP_OPTIONS.h files
1316    o updated results for some of the tests to reflect the new
1317      optfiles (-ieee: -O0 instead of -O3)
1318    
1319    checkpoint51q_post
1320    o cd_code:
1321      - moved cd_scheme.F -> cd_code_scheme.F
1322      - separate read_checkpoint from cd_code_ini_vars.F
1323      - separated cd_code part from write_checkpoint
1324      - updated AD_SOURCE, generated .flow
1325      - added CD_CODE_VARS.h to the_main_loop

1327    o ctrl package totally restructured
1328      - pack/unpack now optional and decoupled from
1329        xx_/adxx_ I/O
1330      - ctrl_pack/unpack cleaned
1331        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1332      - confined inclusion of AD_CONFIG.h to where necessary.
1333    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1334    
1335    checkpoint51p_post
1336    o create initial cd_code package
1337      - WARNING: the initialization of fields within packages
1338        is broken because INI_FIELDS (where READ_CHECKPOINT is
1339        called) is called *before* PACKAGES_INIT_VARIABLES.
1340        This seems to be backwards since
1341        1) its important to initially zero the entire field including
1342           the "halo" region
1343        2) zeroing needs to be done *before* reading pickup info
1344           and the pickup call might or might not happen in any
1345           particular run
1346      - this needs an overhaul for R2
1347    o cleanup verification/*/code/GMREDI_OPTIONS.h
1348    o cleanup testreport
1349    
1350    checkpoint51o_post

1358    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1359    o bug fix in find_alpha.F for MDJWF:
1360      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1361        change rho -> rho-rhoConst
1362      - replace call find_rho to find_rhonum

1381      - moved surfaceTendencyTice from pkg/seaice to main code
1382      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1383      - subroutine FREEZE now limits only surface temperature
1384        (this means new output.txt for global_ocean.90x40x15,
1385         global_ocean.cs32x15, and global_with_exf)
1386    o added surface flux output variables to TIMEAVE_STATVARS
1387    
1388    checkpoint51n_pre
1389    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

1411    o enable to apply restoring on S & T only in a latitude band.
1412    o update output (external_forcing_surf modif. change truncation errors)
1413       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
1414    
1415    checkpoint51k_post
1416    o change default to: useNHMTerms=.FALSE.
1417     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):

1512      - debLevA: standard
1513      - debLevB: equivalent to current debugMode=.TRUE.
1514    o introducing pathname variable mdsioLocalDir for mdsio
1515      that can be specified at runtime
1516      (relevant for cluster I/O to local disk)
1517    `
1518    >>>checkpoint51b_post
1519    adjoint of ptracers
1520    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
1521    o extended state in checkpoint_lev?, etc.
1522    o alternative ctrl/cost with tr1 or ptracer
1523    o new comlev1_bibj_ptracers
1524    o new ptracers.flow
1525    o made ptracers_forcing same as external_forcing_s
1526    o added verification for adjoint with ptracers
1527      - adm. grdchk fail so far
1528      - tlm. grdchk OK
1529      - checked tapelev/comlev recomputations: OK
1530    <<<checkpoint51b_pre
1531    
1532    checkpoint51a_post
1533    o added code for biogeochemistry package
1534      - new pkgs: dic, gchem
1535      - new subroutine in ptracers
1536    o modify code for biogeo packages
1537      - in model/src and pkg/ptracers
1538    
1539    checkpoint51
1540    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1541      - autodiff, ctrl, exf, grdchk, seaice
1542      kept separate packages
1543      - cost, ecco, obcs
1544    o updating verification/internal_wave, verification/lab_sea
1545      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1546    
1547    checkpoint50i_post
1548    o Preparing next differentiable checkpoint and sync
1549      of MAIN vs. ecco-branch
1550      - 1st step: this one is differentiable
1551      - 2nd step: next(! not this) checkpoint will have updated packages
1552                  from ecco-branch)
1553    
1554    checkpoint50h_post
1555    o new package "land": provide surface BC for AIM.
1556    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1557    o AIM: use true log-P extrapolation for near surface temp (= as in
1558        F.Molteni paper) ; update aim.5l_cs output.
1559    o New variable in PARM03 for more flexible pickups
1560    o somewhat cleaned package initialisation sequence for
1561      ctrl/ cost/ ecco/ in packages_... routines
1562    
1563    checkpoint50g_post
1564    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1565      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1566      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1567        made the default because of faster convergence than ADI
1568    
1569    checkpoint50f_post
1570    o exf totally restructured
1571      - replaced all exf_set_ routines by one generic exf_set_gen.F
1572        and made sure it's still differentiable
1573      - split exf_getffields.F into new exf_bulkformulae.F
1574      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1575      - updated adjoint/makefile and relevant verif. accordingly
1576    
1577    checkpoint50f_pre
1578     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
1579          + change Evap over land. (update aim.5l_cs output)
1580     o added missing .cvsignores and made uniform across expts
1581     o changed configuration of tidal_basin_2d expt
1582     o added pkg/debug functions for tracing code in fatal crashes
1583     o tidied pkg/monitor to use MONITOR_OPTIONS.h
1584     o new fn in pkg/monitor to stop model if solution grows too big
1585     o removed lots of single quotes from comments
1586    
1587    checkpoint50e_post
1588    o make KPP work with PTRACERS
1589     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1590       nearly a copy of kpp_transport_s
1591     - there is no analogue to SurfaceTendencyS, so I have to use
1592       gPtr(of the surface layer) instead
1593    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1594    checkpoint50e_pre
1595    
1596    checkpoint50d_post
1597    o change kpp output from multiple-record state files to single-record state
1598      files analogous to write_state.F
1599    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1600      analogous to the cg2d-related output.
1601    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1602      so that writing to internal file fn (with length 512) fails.
1603    checkpoint50d_pre
1604    
1605    checkpoint50c_post
1606    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1607    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1608    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1609    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1610    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1611    
1612    checkpoint50c_pre
1613    Merging from release1_p13:
1614    o bug fix for pkg/seaice dynamic solver
1615    o Added SEAICE_initialHEFF to pkg/seaice
1616    
1617    checkpoint50b_post
1618    o store u*,v* in gU,V instead of in guNm1,gvNm1
1619    o in order to put the momForcing out of the Adams-Bashforth:
1620      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1621      to timestep.F
1622    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1623    o re-generate output for highly sensitive test-exp:
1624       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1625    
1626    checkpoint50b_pre
1627    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1628    o corrected CPP option mismatch in exf_Bulk... functions for case
1629      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1630    
1631    checkpoint50a_post
1632    o Bug fix for merging between c50 and KPP.
1633      ikey was passed from thermodynamics to kpp_calc via
1634      common block rather than being recomputed in kpp_calc,
1635      in contradiction with new key itdkey.
1636      New key ikppkey created, and tamc.h headers updated.
1637    
1638    checkpoint50
1639    - 2nd step of merge with ecco-branch:
1640      merge changes in ecco-branch back into main trunk
1641    - bug fix in find_alpha
1642    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1643    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1644    - merged some sliced AD support routines
1645    
1646    checkpoint49
1647    merged from ecco-branch:
1648    o exf:
1649      - Enable initialisation of forcing fields to constant
1650        (runtime) values.
1651      - in exf_getffields.F
1652        Reduce i-/j-loop to interior domain, discarding overlaps.
1653        That also fixes wrong TAF-key computations for key_1, key_2
1654        with bulf formulae.
1655      - exf_init.F modify #ifdef for exf_init_evap
1656      - exf_getffieldrec.F, ctrl_getrec.F
1657        The following INT-usages are not safe:
1658          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1659          fldcount = int(fldsecs/fldperiod) + 1
1660        and were modified.
1661    o autodiff: checkpoint_lev...
1662      - updated storing for bulk formulae (some arrays were missing)
1663      - added state for seaice package
1664      - synchronized with main branch
1665    o DIVA:
1666      Modif.s in
1667      - the_main_loop.F
1668      - the_model_main.F
1669      and added cost_final_restore.F cost_final_store.F
1670      o With these changes, it is possible to fully separate
1671        the first forward run to compute the cost function (mdthe_main_loop)
1672        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1673        into separate model executions.
1674        This enables better tuning of DIVA to given queue sizes.
1675      o Loss of cost function value in consecutive DIVA runs is
1676        fixed by storing to 'costfinal' file.
1677      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1678        beginning/end of adjoint integration is accounted for.
1679      The current changes apply to TAF-1.4.26.
1680      TAF has one remaining bug, requiring one manual change
1681      (see MITgcm manual).
1682    o cal: synchronized between MAIN and ecco-branch
1683    
1684    checkpoint48i_post
1685    o Changes to restore differentiability of code w.r.t. previous tag
1686      (mostly adding new routines to make list and replacing
1687      pressure by totPhiHyd).
1688    o Updated and merged grdchk package
1689      - has both ADM and TLM checks
1690      - works for single- and multi-proc.
1691      - output cleaned
1692      - worked successfully for parallel DIVA
1693    o genmake:
1694      - Adding -platform=SP4
1695      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1696    o Modif. for DIVA:
1697      ctrl_unpack should not be called in intermediate DIVA interval.
1698      (similar thing would apply for active files such as
1699      tbar, sbar, psbar, which should not be reinitialised;
1700      only relevant for ecco-branch)
1701    
1702    checkpoint48h_post
1703    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1704    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1705    o Added SEAICE_initialHEFF to pkg/seaice
1706    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1707    
1708    checkpoint48g_post
1709    --- EOS:
1710    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1711      store total Potential in totPhyHyd for diagnostics & EOS.
1712    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1713    --- Pressure/geopotential gradient:
1714    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1715    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1716      ( changes results of global_ocean_pressure )
1717    o NLFS + z-coord.: add eta*Rho' contribution.
1718    o accurate phiHyd when using interface-W at the middle between 2 centers
1719     ( changes results of ideal_2D_oce )
1720    o includes r* 2nd term in potential gradient.
1721    
1722    checkpoint48f_post
1723    Merging from release1_p12:
1724    o Modifications for using pkg/exf with pkg/seaice
1725      - improved description of the various forcing configurations
1726      - added basic radiation bulk formulae to pkg/exf
1727      - units/sign fix for evap computation in exf_getffields.F
1728      - updated verification/global_with_exf/results/output.txt
1729    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1730      (SBO) core products, including oceanic mass, center-of-mass,
1731      angular, and bottom pressure (see pkg/sbo/README.sbo).
1732    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1733      to avoid negative values in shallow regions.
1734      - updated verification/natl_box/results/output.txt
1735      - updated verification/lab_sea/results/output.txt
1736    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1737    o Added useSingleCpuIO option (see PARAMS.h).
1738    o Updated useSingleCpuIO option in mdsio_writefield.F to
1739      work with multi-field files, e.g., for single-file pickup.
1740    o pkg/seaice:
1741      - bug fix in growth.F: QNET for no shortwave case
1742      - added HeffFile for specifying initial sea-ice thickness
1743      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1744    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1745      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1746    o pkg/seaice:
1747      - adjoint-friendly modifications
1748      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1749    
1750    checkpoint48e_post
1751    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1752    o dynamics: change definition of computational domain & adapt mom_fluxform
1753      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1754    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1755        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1756        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1757        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1758        inverted_barometer solid-body.cs-32x32x1
1759      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1760    
1761    checkpoint48d_post
1762    o in preparation for r*:
1763     a) use pre-computed gradient of hydrostatic potential:
1764        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1765     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1766        => affects results of glob_oce_pressure (different truncation error)  
1767      update output.txt of ideal_2D_oce & global_ocean_pressure
1768    
1769    checkpoint48d_pre
1770    o in preparation for r*:
1771      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1772      pass the 2 comp. of the grad. as arguments to momentum S/R.
1773      but for the moment, only used if it does not change the results.
1774    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1775    
1776    checkpoint48c_post
1777    Modifications in treatment of initial flux forcing controls
1778    to avoid extra storing of flux fields.
1779    
1780    checkpoint48c_pre
1781    o Added tidal_basin_2d experiment (currently 1D!)
1782    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1783    
1784    checkpoint48b_post
1785    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1786     (modification to pressure gradient not yet implemented)
1787    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1788      (for U & V) that are used for vertical advection of momentum.
1789    
1790    checkpoint48a_post
1791    o In preparation for r*, use temp. array to compute vertical transport
1792       in flux-form momentum pkg. => change results of few test-exp.
1793      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1794                        lab_sea, natl_box & plume_on_slope
1795    
1796    checkpoint48
1797    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1798    
1799    checkpoint47j_post
1800    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1801    o moved adexch from forward_step to addummy_in_stepping
1802    o added exch in ctrl_map_...
1803    o aveFreq.=0. at end of cost_final to avoid overwrite in
1804      reverse checkpointing loop
1805    o Yet more changes in gmredi:
1806      * adgmredi_calc_tensor
1807        avoiding all recomputation of gmredi_slope_limit
1808      * adgmredi_x/y/rtransport
1809        added flag for excessive storing to avoid recomp. of
1810        u/v/rtans, dTdx/y/z
1811        -> this is not really necessary and very memory-consuming
1812      * adgmredi_slope_psi:
1813        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1814      * gmredi_slope_limit
1815        re-activated full calculation of taperfct for case 'ac02'
1816    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1817    
1818    checkpoint47i_post
1819    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1820    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1821      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1822    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1823    o gmredi: fix few bugs.
1824    
1825    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1826    This will be a good checkpoint to plug into the ecco-branch.
1827    o few modif.'s to get latest version adjointed
1828      (mainly kick out code in ini_linear_phisurf)
1829    o modif's to run adjoint with exactConserv
1830    o case GM_BOLUS_ADVEC should be cleaned
1831      S/R gmredi_slope_psi should be cleaned
1832    o verification/carbon now has exactConserv=.TRUE.
1833    
1834    checkpoint47g_post
1835    o time-average AIM output: becomes independent from statvars time-average
1836      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1837    o After TAF bug fix:
1838      Tested adjoint of gmredi package.
1839      Tests were done with checkpoint47 rather than with latest
1840      checkpoint47f_post since the latter is broken for the adjoint
1841      verification/carbon/ contains both ADM and TLM gradient checks.
1842    Here they are, before they get changed/lost/stolen.
1843    Mostly modif.'s to fix numerical sensitivities.
1844    Gradient checks OK for
1845    - GM_taper_scheme:
1846      * clipping
1847      * ac02
1848      * linear
1849      * glw91
1850      * dm95
1851      * ldd97
1852    - GMREDI_OPTIONS:
1853      * GM_VISBECK_VARIABLE_K
1854      * GM_NON_UNITY_DIAGONAL
1855      * GM_EXTRA_DIAGONAL
1856      * GM_BOLUS_ADVEC
1857    in conjunction with data.gmredi parameters to be checked in
1858    in a few minutes under verification/carbon/code/
1859    
1860    checkpoint47f_post
1861    Merging from release1_p10:
1862    o modifications for using pkg/exf with pkg/seaice
1863      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1864        and SEAICE_EXTERNAL_FLUXES
1865      - pkg/exf CPP options EXF_READ_EVAP and
1866        EXF_NO_BULK_COMPUTATIONS
1867      - usage examples are Experiments 8 and 9 in
1868        verification/lab_sea/README
1869      - verification/lab_sea default experiment now uses
1870        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1871    
1872    checkpoint47e_post
1873    o created a tag prior to creating a branch
1874    
1875    checkpoint47d_post
1876    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1877      at the bottom boundary had an erroneous half slip boundary condition
1878    o added bottom drag and no slip boundary condition capabilities to
1879      oceanic pressure coordinates code
1880    o added new verification experiment global_ocean_pressure, this experiment is
1881      also described in the tutorial section of the manual
1882    checkpoint47d_pre
1883    
1884    checkpoint47c_post
1885    o Added a verification experiment for a global cubed-sphere ocean run
1886      -  verification/global_ocean.cubed32x32x30
1887      -  uses pkg/therm_seaice and pkg/bulk_forcing
1888    
1889    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1890    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1891      when using P-coordinate; only implemented for atmospheric config.
1892    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1893      NOTES: requires option NONLIN_FRSURF to be "#define".
1894    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1895    
1896    checkpoint47b_post
1897    Merging from release1_p9:
1898    o pkg/seaice
1899      - removed GOTO's and added taf directives
1900      - double precision constants to reduce the g77 (Linux)
1901        to F77 (SGI) differences reported in release1_p8
1902    o tools/genmake
1903      - added SGI options
1904    o verification/testscript
1905      - updated to that of checkpoint47a_post
1906    o verification/global_ocean.90x40x15/input/eedata
1907      - modified for SGI f77 compatibility
1908    o verification/lab_sea
1909      - added description of sea-ice model
1910      - added missing matlab routines
1911      - added test of thermodynamics parallelization
1912    
1913    checkpoint47a_post
1914    o new pkg: aim_v23
1915     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1916       for now, keep the same surface forcing as before.
1917     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1918     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1919     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1920    o add diagnostic of surface correction term in monitor output
1921    
1922    o bulk_force and therm_seaice
1923    - Two packages:  bulk_force (Bulk forcing)
1924      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1925    - Earlier integration from Stephaine Dutkiewicz
1926      and Patrick Heimbach.
1927    - Two ifdef statements for compile time,
1928       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1929    
1930    checkpoint47
1931    differentiable version of checkpoint46n_post
1932    o bug fix in quasihydrostaticterms
1933    o * "clean" adjoint code (in terms of extensive recomputations)
1934        can now be obtained for all GMREDI options (i.e. for
1935        - GM_VISBECK_VARIABLE_K
1936        - GM_NON_UNITY_DIAGONAL
1937        - GM_EXTRA_DIAGONAL
1938        - GM_BOLUS_ADVEC )
1939      * However, wrong gradient check problem remains unsolved.
1940      * New CPP options have been introduced for different
1941        tapering schemes
1942    o external_fields_load now part of differentiation list
1943    o pressure needs multiple storing;
1944      would be nice to have store_pressure at beginning or
1945      end of forward_step, e.g. by having phiHyd global (5-dim.)
1946      (NB: pressure is needed for certain cases in find_rho,
1947      which is also invoked through convective_adjustment).
1948    o recomputations in find_rho for cases
1949     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1950    o #define ATMOSPHERIC_LOADING should be differentiable
1951    o ini_forcing shifted to begining of initialise_varia
1952    o Incorporating QNVS line search routines into MITgcm
1953      (this is separate code, and therefore not under pkg)
1954      lsopt/, optim/
1955    o Updated verification/carbon/
1956      - #define GM_VISBECK_VARIABLE_K
1957      - GM_taper_scheme    = 'ldd97'    
1958    
1959    checkpoint46n_post
1960    Merging from release1_p8:
1961    o verification/natl_box:
1962      updating new external_fields_load routine
1963    o New package: pkg/seaice
1964      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1965      The sea-ice code is based on Hibler (1979-1980).
1966      Two sea-ice dynamic solvers, ADI and LSR, are included.
1967      In addition to computing prognostic sea-ice variables and diagnosing
1968      the forcing/external data fields that drive the ocean model,
1969      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1970      The implied surface heat flux is then stored in variable
1971      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1972      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1973      non-local transport term.  Because this call precedes model
1974      thermodynamics, temperature under sea-ice may not be "exactly" at
1975      the freezing point by the time theta is dumped or time-averaged.
1976      N.B.: fairly large differences in accuracy occur across
1977            different platforms/compilers; comparison between
1978            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1979            generated output gives:
1980       T           S           U           V
1981      C D M    c        m  s        m  s        m  s        m  s
1982      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
1983      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d
1984      g d e n  d  n  x  n  .  n  x  n  .  n  x  n  .  n  x  n  .
1985    
1986      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1987    o GAD:
1988      - generated new common blocks to account for call of
1989        same gad routines with differing traceridentities
1990        (needed to modify tracerIdentity indices in GAD.h)
1991      - generated separate common blocks for case useCubedSphereExchange
1992        (Department of Futurology)
1993      - parameter lists to gmredi_?transport: added tracerIdentity
1994      - added new key indices to tamc.h
1995    o external_fields_load:
1996      - added this routine to TAF list
1997      - needed to make some common blocks global and additional storing
1998        along the same lines as exf package (checkpoint_lev?_directives.h)
1999    o exf:
2000      updated external forcing package
2001      - bug fixes carried over from ecco-branch
2002        (missing OBCS_OPTIONS.h in two routines)
2003      - enable easy to use "no forcing".
2004      - added exf I/O for atmospheric loading
2005      - added exf I/O for runoff data
2006      - transfered scaling between exf <-> MITgcm to exf namelist
2007    o Adding new verification experiment global_with_exf.
2008      This verification experiment is almost identical to the
2009      global_ocean.90x40x15 experiment, except that it uses
2010      the exf (and cal) package instead of the
2011      external_fields_load routine (cf README file).
2012    
2013    checkpoint46m_post
2014    o modified testscript to return -- when there are no lines of "%MON" output
2015    o added new flag "quasiHydrostatic" for QH mode
2016      and new routine quasihydrostaticterms()
2017    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
2018      New routine: mom_u_coriolis_nh()
2019    o fixed sign of non-hydrostatic metric terms in u and v equations.
2020      Depend on correct sign of gravitySign.
2021    o added work.pc* to .cvsignore in aim directories using ifc
2022    o introduced flag for controllin non-hydrostatic metric terms
2023    o removed gravitySign from PARM04
2024    o switched to g77/ifc from pgf77 in aim experiments
2025    
2026    checkpoint46l_post
2027    o made convective adjustment work with pressure coordinates:
2028     - changed the direction of k-loop in convective_adjustment.F for the
2029       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
2030     - adjusted the reference pressure k-index in convective_adjustment.F
2031     - adjusted the convection condition in convect.F (in analogy to
2032       calc_ivdc.F)
2033     - convective_adjustment no longer computes anything on the halos
2034     - removed the warnings about negative salinity from find_rho.F and
2035       find_alpha.F; instead the new routine look_for_neg_salinity, called
2036       at the beginning of find_rho, find_alpha, and find_beta, does a
2037       check of the entire slice, if CPP-option
2038       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
2039    checkpoint46l_pre
2040    
2041    checkpoint46k_post
2042    o fixed the verification/global_ocean.90x40x15 experiment:
2043     - new bathymetry (the world according to A., JMC, and M.)
2044     - new initial fields and forcing fields (*.bin files)
2045     - new POLY3.COEFFS (for the next release one should switch to a full
2046       equation of state: JMD95P or MDJWF)
2047     - fixed several errors and redundancies in the data file
2048     - experiment uses looped cells
2049     - added matlab directory with diagnostic scripts for plotting of output
2050    
2051    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
2052     - read AIM physics parameters from a file (data.aimphys)
2053     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
2054    
2055    checkpoint46j_post
2056    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
2057    o move wVel computation at the end of the time step, in S/R integr_continuity
2058    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
2059    o update timeave pkg for wVel diagnostic.
2060    checkpoint46j_pre
2061    
2062    checkpoint46i_post
2063    o Clean up AIM package (and keep the results unchanged):
2064      include CPP_OPTION and use IMPLICT NONE in all routines ;
2065      declare all the variables _RL ; use _d 0 for all numerical constants.
2066      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
2067    
2068    checkpoint46h_post
2069    o cleaned up the use of rhoNil and rhoConst.
2070      - rhoNil should only appear in the LINEAR equation of state, everywhere
2071        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
2072        and the dynamical equations are all divided by rhoConst
2073    o introduced new parameter rhoConstFresh, a reference density of fresh
2074      water, to remove the fresh water flux's dependence on rhoNil. The default
2075      value is 999.8 kg/m^3
2076    o cleanup up external_forcing.F and external_forcing_surf.F
2077      - can now be used by both OCEANIC and OCEANICP
2078    checkpoint46h_pre
2079    
2080     Added code to convert surface volume flux (fresh water) into
2081     a mass flux when using P coordinates in the ocean (OCEANICP).
2082     Note: It assumes you have set rho0=rhoConst=density of fresh water.
2083    
2084    checkpoint46g_post
2085    o Include a new diagnostic variable phiHydLow for the ocean model
2086      - in z-coordinates, it is the bottom pressure anomaly
2087      - in p-coordinates, it is the sea surface elevation
2088      - in both cases, these variable have global drift, reflecting the mass
2089        drift in z-coordinates and the volume drift in p-coordinates
2090      - included time averaging for phiHydLow, be aware of the drift!
2091    o depth-dependent computation of Bo_surf for pressure coordinates
2092      in the ocean (buoyancyRelation='OCEANICP')
2093      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
2094        Theta, Salinity, and Pressure in the parameter list. This routine is
2095        presently contained in find_rho.F. This routine does not give the
2096        correct density for 'POLY3', which would be a z-dependent reference
2097        density.
2098    o cleaned up find_rho
2099      - removed obsolete 'eqn' from the parameter list.
2100    o added two new verification experiments: gop and goz
2101      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
2102    checkpoint46g_pre
2103    
2104    checkpoint46f_post
2105    o Enable tangent linear (forward mode) gradient checks:
2106      - extended active file handling to g_... files
2107      - added TANGENT_SIMULATION to theSimulationMode
2108      - extended grdchk package accordingly
2109    o added tangent linear setup in verification/carbon/code_ftl
2110    o added adjoint setup in verification/front_relax/code_ad
2111    
2112    checkpoint46e_post
2113    o Added new equation of state -> MDJWF
2114      - EOS of McDougall et al., 2002, JAOT, submitted
2115      - caveat: the equation of state is only valid for a smaller (more
2116        realistic?) range of values than JMD95P/Z and UNESCO
2117      - added masks to the calculation of pressure in store_pressure
2118      - added more check values for density in check_eos (ini_eos.F), some of
2119        the old check values are out of the range of the MDJWF-eos, so don't
2120        expect perfect matches for those
2121    checkpoint46e_pre
2122    
2123    checkpoint46d_post
2124    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
2125      'OCEANICP', also initialised field pressure correctly in ini_eos in the
2126      case of pressure coordinates. eosType='JMD95Z' in
2127      combination with buoyancyRelation='OCEANICP' now causes an error.
2128    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
2129      in find_alpha/beta.
2130    checkpoint46d_pre
2131    
2132    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
2133      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
2134    
2135    checkpoint46c_post
2136    o Changes necessary for ocean in p-coordinates
2137     -  Added new buoyancy relation = 'OCEANICP'
2138     -  Added new parameters = gravitySign (this used to be contained inside
2139        the factor dRdZ which I added when we first switched to R coordinates).
2140     X GM/Redi is not compatible (yet)
2141     X bottom drag and no-slip need to be debugged.
2142    checkpoint46c_pre
2143    
2144    checkpoint46b_post
2145    o Added new equation of state -> JMD95Z and JMD95P
2146      - EOS of Jackett and McDougall, 1995, JAOT
2147      - moved all EOS parameters into EOS.h
2148      - new routines ini_eos.F, store_pressure.F
2149    o Added UNESCO EOS, but not recommended because it requires
2150      in-situ temperature (see JMD95)
2151    o Modified formatting for knudsen2.f in utils/knudsen2 and added
2152      unesco.f to be used with POLY3
2153    checkpoint46b_pre
2154    
2155    checkpoint46a_post
2156    o Added (atmospheric) pressure loading
2157      - new field in FFIELDS.h, etc...
2158      - new cpp flag ATMOSPHERIC_LOADING
2159    o Changed hFacC to _hFacC in calc_phi_hyd.F
2160    o Added SHORTWAVE_HEATING to some files for consistency
2161    checkpoint46a_pre
2162    
2163    checkpoint46
2164    further merges from release1_p5
2165    o new ctrl package
2166      - adopted from ECCO environment to enable optimization
2167      - added Eliassen Palm fluxes to controls
2168    o added Eliassen Palm flux controls to gradient check package
2169    o cost package
2170      - Compatible with new ctrl package
2171      - added Eliassen Palm cost hooks
2172      - modif's of existing cost functions
2173    o Adjoint-related bug fixes in kpp:
2174      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
2175      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
2176    o autodiff package
2177      - flow directives:
2178        + new for S/R do_the_model_io
2179        + enhanced for S/R checkpoint
2180        + new gmredi.flow
2181      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
2182        disable adcommon.h/g_common.h by default.
2183      - fixed problem for adjoint of global_max
2184    o modified verification/carbon/
2185    o New setup for adjoint of global_ocean
2186    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
2187    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
2188    o incorporated hooks for sponge layer code (external_forcing.F)
2189    
2190    checkpoint45d_post
2191    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
2192    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
2193      (affects plume_on_slope "cg2d" output)
2194    o add new parameter deltaTfreesurf for free-surface time stepping
2195    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
2196    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
2197    o change phiMin in exp1 (to agree with documentation)
2198    o add new flags:
2199     - T,S forcing inside/outside Adams-Bashforth
2200     - turn off temp,salt advection and/or forcing
2201     - for each tracer, define internal flag for multiDimAdvection & A-B
2202    o monitor: change definition of KE to check conservation of Energy
2203    
2204    checkpoint45c_post
2205    o Removed f90 comments ("!")
2206    o Modified initialisations to enable exf package for MITgcm
2207      (without invoking ECCO_PACKAGE).
2208    o modifications to gradient check package (Martin Losch)
2209      - enable centered differences
2210      - modified format of standard output
2211    
2212    checkpoint45b_post
2213    o cleaned exchange calls in cg2d
2214    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
2215    o included CPP option SINGLE_LAYER_MODE in thermodynamics
2216      to configure barotropic setup (Martin Losch)
2217    o moved some initialisations within bi,bj loop in dynamics
2218      (TAF flow dependency)
2219    o in initialise_varia, moved call packages_init_variables
2220      before convective_adjustment_init
2221      (corresponding adjustment of TAF tape initialisation).
2222    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
2223    
2224    checkpoint45a_post
2225    o compute Rho over the whole domain (extend iMin,jMin indices)
2226    o specific exchange for X-slice domain (case Ny=1)
2227    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
2228    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
2229    
2230    checkpoint44h_post = checkpoint45
2231    o Fix to restore differentiability:
2232      place at which packages_init_variables is called in
2233      initialise_varia is crucial for reverse control flow.
2234    o modifications in GMRedi to enable stable adjoint
2235      (corresponding modif's in thermodynamics, dynamics)
2236    o added missing hook for sponge layer code in external_forcing
2237    o modified test cost functions
2238    o storing in gad_advection (plus removal of write(0,*)!
2239    o missing headers TR1.h added in convective_adjustment routines
2240    o errorMessageUnit set non-equal zero in eeboot
2241      (conflict on some platforms, e.g. IBM SP3)
2242    o modified carbon verif.
2243    
2244    checkpoint44h_pre
2245    o vertical grid option: allow to put the Interface at the middle between
2246      2 cell-centers ; replace delZ in pkg/kpp by drF.
2247    o GM Advective form: Tracers are advected using the residual transport (=
2248      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
2249    
2250    checkpoint44g_post
2251    o fix surface correction term in multiDimAdvection (affects plume_on_slope
2252      results) ; ifdef missing in thermodynamics.F
2253    
2254    checkpoint44f_pre,checkpoint44f_post
2255    o added PTRACERS package
2256      This allows an arbitrary number of passive tracers to be integrated
2257      forward simultaneously with the dynamicaly model.
2258      + Implemented so far:
2259        - basic forward algorithm (time-stepping, advection, diffusion, convection)
2260        - I/O and checkpointing
2261        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
2262      + Not implemented so far:
2263        - KPP
2264        - OBCS
2265      + No specific example supplied (yet) but global_ocean.90x40x15 has the
2266        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
2267        line in data.pkg.
2268      + This package is disabled by default since it increases storage.
2269    
2270    
2271    o testscript: added -cleanup option
2272    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
2273                 b) enable to filter 2D fields.
2274    
2275    checkpoint44e_pre,post
2276    o re-wrote convective adjustment to use pre-calculated weights
2277      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
2278      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
2279      Original calls to convect() still in place.
2280    
2281    chkpt44d_pre,post
2282    o added missing EXCLUDE_MONITOR flags
2283    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
2284      (incompatible typ in MIN/MAX expressions caused problems
2285      on IBM SP3)
2286    o in genmake added variable MAKEDEPEND
2287      plus resetting for case SunOS
2288    o added timer_stats.c routine for IBM SP3
2289    o removed variables in dynamics
2290    !!! I forgot to create tag chkpt44d_pre !!!
2291    !!! But chkpt44d_pre = chkpt44c_post    !!!
2292    
2293    o real fresh water flux implemented with non-linear free-surface.
2294    
2295    chkpt44c_pre,post
2296    o few fix (mask in shap_s2, EmPmR in external_field_load,
2297      USE_NATURAL_BCS in solve_for_P);

2328    
2329    checkpoint42
2330      Fixed AD-related problems:
2331    o Store directives up-to-date with re-arranged Adams-Bashforth
2332      (mainly thermodynamics.F)
2333    o New store directives for multi-dim. advection schemes
2334      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
2335      * new common block and key passkey

2357    o modifications for non-linear free-surface
2358    o fixed conditionals for fixed flow/passive tracer only mode
2359    o added tension/strain form of stress tensor
2360    o changes to commenting of arguments for TAF/TAMC
2361    o added/updated many matlab scripts
2362    o added multi-dimensional advection method for tracers
2363      
2364    checkpoint40pre8
2365    o new package rw/
2366      Added method for dumping intermediate local arrays:
2367      mdsio_writetile - same as mdsio_writefield except works from inside
2368                        bi,bj loop
2369      mdsio_writelocal - same as mdsio_writetile except works for local
2370                         arrays
2371      write_local_r? - higher-level wrapper for mdsio_writelocal
2372      Controlled by diagFreq. Defaults to zero (ie. no dumps)
2373      Example given at end of mom_vecinv.F that dumps some local arrays.
2374    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
2375      control flux-form versus vector invariant code.
2376      Switch is runtime flag vectorInvariantMomentum (defaults to false)
2377      or genmake -DISABLE ...
2378    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
2379      (additional storing is now needed for case vecinv;
2380      currently nothing implemented to switch this storing off
2381      in case fluxform is used since no CPP flag available).
2382    
2383    checkpoint40pre7
2384    o bug fix in dynamics.F
2385      calc_viscosity called before k=1,Nr loop.

2390    checkpoint40pre6
2391    o split dynamics into thermodynamics & dynamics
2392    o corresponding split of calc_diffusivity into
2393      calc_diffusivity, calc_viscosity
2394      (kpp_calc_diff, kpp_calc_visc).
2395    o Added diffkr, kapgm to control variables
2396    o bug fix in gmredi_slope_limit for ldd97
2397    
2398    checkpoint40pre5
2399    o proper initialization of Adams-Bashforth time stepping
2400      + uses forward step for very first step of model (iter=0)
2401    o re-generated *all* output since almost all output is modified by this
2402      change (sorry but we've been putting this one off for about 2 years)
2403      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
2404        *not* regenerated since they are already out of date and I don't
2405        want to create the impression that they are suddenly working.
2406    o removed KAP stuff for DEC's
2407    o modified/added many .cvsignore files in */code and */input
2408    o added new expt "solid-body.cs-32x32x1"
2409      + this uses an alternative form of ini_curvilinear_grid.F which
2410        is not necessarily any better than the current one...
2411    
2412    checkpoint40pre4
2413    o added re-initialisations of utrans,vtrans,rtrans in
2414      calc_common_factors which are crucial for TAF.
2415    o extended iMin,jMin range for calc_common_factors,
2416      calc_diffusivity

2423    o some recomputations of nIter0 for TAMC
2424    
2425  checkpoint40pre2  checkpoint40pre2
2426  o Updated to latest branch of AJA, JMC  o Updated to latest branch of AJA, JMC
