5      ==============================      ==============================
6    
7    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
8      include it only where its needed
9    o move balancing of fluxes before the call of external_forcing_surf
10    o seaice:
11      - correct units of turning angles (now they are really in degrees)
12      - move computation of GWATX/Y out of main routine into dynsolver
13      - initialize GWATX/Y in seaice_init
14    o Apply mask on Fresh-Water flux (needed for SSH forcing).
15      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
16    o seaice: add runtime flags for turning angles (default to zero)
17    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
18      and trend from exf forcing and ctrl control adjustments
19    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
20      (since checkpoint57x_post)
21    o change the default rotation period to 86164.s = the Earth rotation
22    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
23      and based on a reference stratification. Tested within hs94.cs-32x32x5.
24    o seaice advection: add code for choosing between the default (2nd order
25      central differences) and multiDim advection schemes provided by
26      pkg/generic_advdiff
27    o seaice:
28      - removed all references to SEAICE_GRID.h fields from
29        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
30        (cubed-sphere configuration will change a little)
31      - grid computations in seaice_init are obsolete now.
32      - cleaned up code a little so that is easier to read (hopefully).
33      - added new (better?) discretizations of default advection and diffusion
34        (turn on with SEAICEuseFluxForm)
35      - replace 1 in 3d global fields by kSurface in growth.F
36      
37    checkpoint58a_post
38    o seaice:
39      - bug fix in advect.F
40    o shelfice:
41      - separate shelfice load anomaly from pload (breaks with time
42        dependent forcing), => introduce constant field shelficeLoadAnomaly.
43        Its default is 0., but it may be computed more cleverly from (unknown)
44        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
45        done offline. A good approximation of the pressure load anomaly is
46        necessary to avoid large initial adjustment processes underneath
47        deep-reaching shelfice.
48      - small fix in ISOMIP shelfice_thermodynamics
49      - add more sophisticated thermodynamics of Hellmer (1989), this is
50        now the default
51      - give a few constants more intuitive names
52    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
53      if bulk formulae are used in long integration (especially EmPmR). Turn
54      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
55      if balancePrintMean, the imbalance that is substracted is printed to
56      STDOUT.
57    o fix bug (typo) in obcs_apply_eta.F
58    o add a new package shelfice which enables us to model the circulation
59      underneath shelf-ice with draughts of hundreds of meters.
60     - works
61     - to do: + include improved thermodynamics
62              + check whether kSurfC (from model/inc/SURFACE.h) can be used
63                instead of new field kTopC
64              + can we use topoFile, Ro_surf and existing code in ini_depth.F
65                instead of new field R_shelfIce and new code in ini_depth.F
66                and ini_mask_etc.F?
67              + adjust vertical mixing schemes?
68    o seaice pkg:
69     - add a cpp-flag to include a simple formula for a salinity dependent
70       freezing point of sea water at the surface
71     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
72       meridional stresses are now different (and hopefully correct)
73    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
74       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
75       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
76    o pkg/diagnostics: add options and parameters for regional-statistics
77       diagnostics ; define regions by reading a region-mask from a file
78       (might add other options later)
79    o pkg/bulk_force:
80     - add option and parameters to use AIM surface-flux formulae.
81     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
82       others forcing fields (defined in PARM05, parameter file "data") are loaded
83       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
84     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
85     - use the right EXCH call for uwind,vwind (to work on CS-grid).
86     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
87       and parameters (note: calcWindStress replaces .NOT.readwindstress).
88     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
89    
90    checkpoint58
91    o add "--embed-source" option to genmake2 which, when the supporting
92      tools can be compiled (as determined by genmake2) will turn on the
93      embed_files package which then embeds the entire MITgcm source code
94      (*.[fFhc] + Makefile) used for the build within the executable
95      - requested by CNH but off by default
96      - adds a paltry <9MB to the mitgcmuv executable in most cases
97      - only writes the output when useEMBEDSRC in eedata is true
98    o clean up 3-dim. relaxation codes:
99      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
100      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
101      * Thanks to Tom Haine for testing!
102    
103    checkpoint57z_post
104    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
105      affects output (@ truncation level) of exp. plume_on_slope ; updated.
106    o fix the pickup behavior for obcs in combination with ptracers
107    o fix a bug in ptracers_external_fields_load
108    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
109      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
110    o transfered surface NH pressure to eta field (if exactConserv).
111    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
112         and update lab_sea output.txt file.
113    o completing 3-dim. relaxation code: additional term
114         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
115      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
116      * At compile time, in "EXF_OPTIONS.h" set
117          #define  ALLOW_CLIMTEMP_RELAXATION
118          #define  ALLOW_CLIMSALT_RELAXATION
119      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
120          tauThetaClimRelax3Dim = 15552000.0,
121          tauSaltClimRelax3Dim  = 15552000.0,
122      * 3 cases:
123          1) Use a constant-in-time 3-dim. field
124          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
125          3) Real-time relax. to time-evolving prescribed field
126    o Adding Laplacian-type smoothness constraint on
127      initial and boundary (forcing) controls (ic, bc)
128      * enable at compile-time via
129        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
130      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
131      * Absolute scale somewhat unclear so far
132      * no area weighting was included since no other cost term does so far
133    
134    checkpoint57y_post
135    First step for a NLFS adjoint
136    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
137    o new init. routines for calc_r_star, calc_surf_dr
138    o still need to deal with ini_masks_etc
139    o testreport seemed happy
140    checkpoint57y_pre
141    
142    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
143    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
144    o add new offset feature to offline pkg (plus minor cleanup)
145    o cfc fixes for final year of integration
146    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
147      be in GCHEM_OPTIONS).
148    
149    checkpoint57x_post
150    o fix testreport Pb in multiple test experiment.
151    o cleanup our namelist syntax in verification:
152      - make it more F95 standards compliant (some work still needed)
153      - allows the vast majority of our tests to work with gfortran
154    o Non-Hydrostatic:
155     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
156     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
157    o Allow to apply AB on T,S rather than on AB(gT,gS):
158     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
159     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
160       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
161     - need a "clever" read_pickup to restart from the other AB formulation
162    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
163    o remove some unused variables (reduces number of compiler warnings)
164    o adjoint
165      * Disable useVariableViscosity for adjoint for time being
166        (there are a number of extensive recomputations)
167      * Initialize certain variables needed for adjoint
168    
169    checkpoint57w_post
170    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
171                 fix the singleCpuIO RS version of MDSWRITEFIELD
172       and add a WARNING if using globalFiles=T with multi-processors.
173    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
174      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
175    o tracer advection scheme:
176      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
177       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
178       was not very convenient).
179      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
180       (further tests needed for the implicit DST & Flux-Limiter schemes).
181    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
182      and sRef for convenience, handy, when you want to initialize
183      ptracers in a large domain with a constant non-zero value. Also,
184      untangle ptracers_init.F a little.
185    
186    checkpoint57v_post
187    o change dome exp. to use variable viscosity in side-drag terms.
188    o remove all the files from the cfc_offline test since they are now
189      incorporated into tutorial_cfc_offline which has been producing
190      identical results for a few days of testing
191    o add new parameter: sideDragFactor to enable half-slip-side BC
192      and change side-drag S/R to use viscosity from mom_calc_visc
193      (can switch back by setting sideDragFactor=0.); affects results at
194      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
195       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
196    o vorticity & strain are now computed without masking, to account for
197      no-slip-side BC in variable viscosity calculation ; mask is applied
198      anyway later on, before computing advection/coriolis terms.
199    o modify exp4 to test new obcs support for reading from external files
200      and for passive tracers
201    o fix behavior of ptracers_monitor when monitor output is written to a
202      netcdf-file; still not independent of monitor.F (writes in the same
203      file).
204    o change default value of tRef (put a uniform, meaningful value for ocean
205      & atmos) and initialize sRef (was missing, as Martin mentioned).
206    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
207      to be proportional to enstrophy dissipation length.  Thus,
208       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
209      This is now consistent with Smagorinsky and with the manual.
210    
211    checkpoint57u_post
212    o OBCS and PTRACERS: add open boundary support for passive tracers
213      - either use homogenous (pseudo) v.Neumann conditions or prescribe
214        OB-values from file; this is not different from the way theta and salinity
215        are treated
216      - however, Orlanski-radiation conditions are not supported, and the model
217        will stop if you use pTracers and Orlanski at the same time.
218      - beefed up the rountine obcs_external_fields_load: now only those open
219        boundary values are overwritten with values from files for which there
220        are really files, otherwise the OB-fields remain untouched. This makes
221        it possible to use different OBs at different ends of the domain (as
222        with EXF)
223    o reduce number of exch calls in shap_filt (s2).
224    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
225      truncation level) 4/5 MLAdjust test results (11&12 digits match).
226    
227    checkpoint57t_post
228    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
229    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
230      same truncation, independent of the face number: affects affects several
231      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
232    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
233      note that biharmonic viscosity + no-slip was not tested in any experiment.
234    o fix bug in non-linear free-surf side-drag ; generate new output for
235      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
236    o make mnc honor the writeBinaryPrec flag for most kinds of output
237    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
238    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
239      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
240    o add brackets in multi-terms sum to get same truncation, independent of
241      the face number (manage to get exactly same value of gU,gV at the cs-edge)
242      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
243    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
244      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
245      a maximum grid-scale Reynolds number.  Also, changes all length calculations
246      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
247      Suggested values of viscosity parameters found in mom_calc_visc.
248      Many new viscosity diagnostics available.
249    
250    checkpoint57s_post
251    o Add clearing-house for viscosity calculations, mom_calc_visc and
252      correct numerous bugs in LeithD and Smagorinsky discretizations.  
253      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
254      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
255      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
256      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
257      The Strain-Tension form is now called with useStrainTensonVisc=.true.
258      ViscAhStrain and viscAhTension are now retired.
259    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
260    o In response to JMC's bug report, genmake2 now ignores any soft-links
261      that it finds in the *current* directory when searching for files.
262      Soft-links found in any other source directories will still work as
263      they did before.
264    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
265      a C routine to unlimit the stack size
266    o mnc-ify pkg/aim snapshot vars
267    o mnc-ify pkg/land as requested by Daniel
268    o various changes to mnc including:
269      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
270      - output can now be grouped so that all files within a group
271          change the ITER portion of their names in lock-step together
272      - can now read ("global") PER-FACE (in addition to PER-TILE) files
273          and works with both EXCH1 and EXCH2 (but needs more testing)
274      - writing works for all verification test cases w/ g77 on Linux
275    
276    checkpoint57r_post
277    o make MNC variable initialization happen earlier
278    o add diagnostics for (almost) each term of the momentum Eq.
279    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
280    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
281    o remove MINIMAL_TAVE_OUTPUT option ;
282      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
283    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
284      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
285    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
286    o add time-dependent SST, SSS control
287    o cost terms in ecco/ modularized (new cost_generic.F)
288    o cost_averages routines are modularized (new cost_averagesgeneric.F)
289    o new infrastructure for seaice model vs. obs misfits in seaice/
290      * driver from the_main_loop.F is seaice_cost_driver.F
291      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
292      * gradient check in Exp. 6a of natl_box_adjoint/
293    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
294      (see README file)
295    
296    checkpoint57q_post
297    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
298    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
299      - bug was reported by Jean-Michel and Ian Fenty
300    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
301      update exp. cpl_aim+ocn output.
302    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
303      Needed for high-res. runs with large global files
304      to be able to limit tapelev size
305    o Changed some tests for adjoint:
306      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
307      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
308      * global_ocean.90x40x15/ back to default 3-level checkpointing
309    o Modifications to enable scripted COMMON to MODULE conversion
310      * verification/OpenAD/code/ has necessary scripts and description;
311      * converts, compiles and runs successfully;
312    
313    checkpoint57p_post
314    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
315    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
316      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
317    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
318    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
319      (was already the case for dissipation with mom_vecinv,
320       and also the case for grad.PhiHyd when staggered-timeStep)
321      This will allow to put dissipation out-off the AB time-stepping.
322     Unfortunately, affects truncation error. Update output of exp. that "fails"
323      (cg2d matching number) and leave the others for later: front_relax(10),
324      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
325      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
326    
327    checkpoint57o_post
328    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
329      (2) its ready to be documented during the 20050801 DocFest
330    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
331      for ideal_2D_oce and lab_sea on linux_ia32_g77
332    o set to #undef CTRL_SET_OLD_MAXCVARS_30
333      in global1x1_tot/code_seaice_adj to access indices 32, 33
334      (worth another tag)
335    
336    checkpoint57n_post
337    o adding precip control xx_precip 32
338    o adding swflux control xx_swflux 33
339    o Replacing 10 forcing penalty cost routines by 1 generic.
340    o Implementing partitioning in time-mean and variable adjustment
341      for atmos. state.
342    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
343    o in natl_box_adjoint:
344      * updated exp 1 to 10
345        (but does not have time-mean vs. variable split results yet)
346    o updated global1x1/*_seaice_adj/
347      to incorporate latest changes
348    o enable useSingleCpuIO for mdsio vector routines
349      (applies in particular to tapelev I/O)
350    o removed inefficient K-loop in all active_file*control*.F
351    
352    checkpoint57m_post
353    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
354      and advect_cs (use EXCH-2 and standard cs-32 grid files).
355    o pkg/exch2: filling of face-corner halo regions is optional
356      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
357    
358    checkpoint57l_post
359     tag before updating tutorials (pre-release-2)
360    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
361       for output and interpolation of input fields onto model grid)
362    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
363       Affects results of exp. rotating_tank ; update output.txt.
364    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
365          and taking the square quantity and/or using a fraction-weight field.
366    o fix aim_diagnostics_init.F mate numbers.
367    o add mnc output capability to diagnostics/diagstat and update
368      our cvsignore files for the ACSII output generated
369    
370    checkpoint57k_post
371    o lab_sea now uses diagnostics package and provides a suite of
372      new EXF diagnostics output.
373    
374    checkpoint57j_post
375    o exf
376      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
377        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
378        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
379      * extended diagnostics output
380        - now includes all EXF variables
381        - hs, hl moved to common block
382        - separate S/R for diagnostics, called after ctrl vector is added
383        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
384        - EXFqnet contains true Qnet (i.e. includes qsw)
385      * updated verif. lab_sea, global_with_exf
386      * Rearranging hflux (exf_mapfields -> exf_getforcing)
387        to ensure that diagnostics sees a true EXFqnet
388    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
389    o diagnostics pkg: change pointers so that 1 diagnostic can be used
390      several times with different frequencies.
391    o mnc-ify the thsice package as requested by Daniel Enderton
392      - the monitor--MNC output needs work
393      - many attributes need to be added (most are currently blank)
394    o mnc-ify theaim_v23 package as requested by Daniel Enderton
395      - many attributes need to be added (most are currently blank)
396    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
397    o add Sadourny like discretization to the 4th.O vorticity advection scheme
398    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
399      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
400         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
401    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
402     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
403    
404    checkpoint57i_post
405    o Diagnostics package was changed: diagnostic allocation is now deactivated
406      by setting an empty file name in the namelist (used to be by setting 0 frequency)
407    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
408      add 1rst Order upwind vertical Shear.
409    o add a quick fix for A/B checkpointing in OFFLINE mode
410    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
411      end-run around the C/Fortran linking horror in eesup/src/timers.F
412    o added pkg/runclock: allows user to terminate run based on wall clock
413    o added non-hydrostatic scaling parameter: nh_am2
414    o pkg/my82: futile attempt to make results compiler-independent by adding
415      some "_d 0", etc. no effect.
416    o for mnc output, fill the 'T' coordinate var with myTime and create a
417      separate 'iter' variable for iteration count
418    o pkg/diagnostics:
419      add new capability: output of Global/Regional & per-level statistics ;
420      tested against monitor output (including land & thSIce) on various exp.
421    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
422    
423    checkpoint57h_done
424      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
425      data.diagnostics, data.gchem, data.ptracers) is done.
426    
427    o pkg/diagnostics: prepare for Global/Regional statistics.
428      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
429    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
430      and rename it: DIFFERENT_MULTIPLE
431    
432    checkpoint57h_post
433    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
434    o pkg/diagnostics: change output frequency, now in seconds (instead
435      of Nb of iterations). This requires to change data.diagnostics.
436    checkpoint57h_pre
437    
438    o in mnc, let the user create the output dir if both mnc_outdir_date
439      and mnc_outdir_num are false
440    o add fflags() to pkg/diagnostics which allows one to specify, on a
441      per-file basis, the file precision [default behavior is unchanged]
442    o added diagnostics to pkg/kpp, including computation of mixed layer
443      depth based on a temperature/density criterion
444    o updated verification/natl_box to test the new pkg/kpp diagnostics
445    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
446    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
447    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
448      not mnc -- this mistake was found by JMC and is now corrected
449    
450    checkpoint57g_post
451    o add Adams-Bashforth 3rd Order time stepping:
452      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
453      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
454    checkpoint57g_pre
455    
456    o make lambda[Theta,Salt]ClimRelax spatially varying
457      (default remains spatially uniform constant based on tau)
458    o added new control variables
459      * init. uVel, vVel, etanN
460      * lambda[Theta,Salt]ClimRelax
461    o separate masks used for ctrl_pack/unpack 'from write_grid' output
462      (suggested by G. Forget)
463    
464    checkpoint57f_post
465    o add parameter "baseTime" = model base time = time at iteration zero
466      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
467      account for baseTime shift
468    o move Coriolis arrays from PARAMS.h to GRID.h
469    checkpoint57f_pre
470    
471    o mnc-ifying the seaice package
472    o introduced an alternative length scale calculation for use in the limiting
473      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
474    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
475    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
476      as well as grad(vort3).  Made it compatible with both approximate form
477      for the cubed sphere and full form of these gradients.  Added flag
478      useFullLeith to select between approximate and full form.  
479    o add "d0" in getcon.F to reduce differences between compilers/platforms
480      update output.txt of exp. fizhi-gridalt-hs
481    o change port_rand funtion to allow to set the seed.
482    o fix obscure MNC bug involving conversion between reals and integers
483      - it caused no problems with certain (eg. gcc, ifc) compilers but the
484        new version is now more standards-compliant
485    o adjoint-related modifications
486      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
487      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
488      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
489    
490    checkpoint57e_post
491    o Adding eddy stress controls a la Ferreira et al.
492    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
493    
494    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
495      update output.txt of exp. fizhi-gridalt-hs
496    o add more "Z" dimensions and associated coordinate vars to MNC
497    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
498    o parameter calendarDumps: when set, approximate months (30-31 days) and years
499      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
500      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
501      months and years.  Requires pkg/cal.
502    o diagnostics: add pickup functionality
503      - off by default for backwards compatibility
504      - current version only uses MDSIO -- MNC will be added
505    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
506    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
507    
508    checkpoint57d_post
509    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
510    o modify verification/ideal_2D_oce so that it tests the creation of mnc
511      output from the diagnostics package
512    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
513    o make genmake2 more portable by using ".$FS" instead of ".f" for more
514      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
515    o add coordinate variables to the MNC output from the diagnostics package
516    o change MNC-flags default value: true when useMNC=TRUE
517    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
518      the ability (off by default) to read the grid information using MNC
519    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
520    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
521    o do snap-shot diagnostics at the middle of the time-interval (instead of
522      at the end).
523    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
524      new test for AIM with thSIce + slab-ocean
525    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
526    o move state variable diagnostics to the beginning of the time step ;
527      (note: still needs some work specially for snap-shot diagnostics)
528      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
529    
530    checkpoint57c_post
531    o Change testing option (-ieee) to get closer agreement between g77 & ifort
532    o generate new output.txt files on faulks with g77 & the new -ieee option
533    checkpoint57c_pre
534    
535    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
536      update output.txt of exp. global_ocean.90x40x15
537    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
538      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
539    o add saltFlux(+File) forcing capability with periodicExternalForcing
540    o allow to use pkg diagnostics for GM-Redi & ThSIce output
541    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
542    o improvements for the MNC output from DIAGNOSTICS:
543      - correct handling of the unlimitied dimension
544      - all dims now have associated coordinate variables
545      - variables located at U, V, and Corner ("Z") points are now written
546        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
547        *all* data points are output
548    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
549    o added pkg/seaice/seaice_monitor.F
550    o mdsio_readfield.F can now read files visible only to master MPI process.
551    o pkg/seaice: some test code for ice-modified ocean stress
552    o exf_getffields interpolation defaults to bilinear for all scalar forcing
553      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
554      spurious negative numbers for precipitation and humidity.  Will cause
555      some small numerical differences for integrations using pkg/exf/exf_interp.F.
556    o pkg/ctrl/
557      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
558        May be enabled via doPackDiag
559      *  introduce z-scaling of
560         + gradient (doZscalePack) and
561         + control (doZscaleUnpack)
562    o pkg/mdsio/
563      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
564      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
565    
566    checkpoint57b_post
567    o simplify options in diagnostics_fill arguments (remove weird combinations)
568    o fix MNC coordinate variables so that they now contain per-face index
569      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
570      general, EXCH2 grids are only aligned to a "local" coordinate system
571    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
572    o Implement instantaneous output within pkg diagnostics:
573      setting a negative frequency in data.diagnostics produces
574     "snap-shot" output (as opposed to time-average if freq > 0)
575    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
576      NOTE: change ptracer diagnostics name: use 2 characters to work with
577            more than 9 tracers. Add also diagnostics of advect & diffus flux.
578    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
579      becomes the coordinate variable for the 'T' dimension
580    o add CF-style coordinate variables to MNC
581      - just a first cut:  numbers are meaningless on the cubesphere and
582        missing along the T axis but otherwise it works!
583    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
584    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
585    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
586      this is based directly on what the model compute, so that the content of
587      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
588    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
589    o clean up build options files for SunOS, in particular
590      - remove -traditional from xmakedepend
591      - change -xarch=v9 to -xarch=native for f77
592      - restore use of make (not gmake)
593      - add CC=gcc if using g77
594    o changes per discussion of AM, JMC, & EH3 today:
595      - move redundant "grid" variables out of "state" -- in preparation of
596        creating proper CF-style coordinate variables and in recognition
597        that any/all grid variables can be easily copied (eg. w/NCO) from
598        the grid files into any of the other NetCDF files
599      - *always* output grid variables with MDSIO (this will eventually be
600        changed)
601      - output MNC grid file if useMNC is true
602    o every instance of _END_MASTER() has been found and replaced with
603      _END_MASTER( myThid ) in order to satisfy certain picky Sun
604      preprocessors
605    o re-arrange diagnostics pkg initialisation:
606     - allow each package to extend the available diagnostics list
607     - add some checking and fix small problems (multi-threaded, ...)
608     - new S/R diagnostics_fill (replace fill_diagnostics):
609       look through the short list of active diag. (instead of the long list)
610       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
611    
612    checkpoint57a_post
613    o this set of changes restores TAMC compatibility
614      tested for global_ocean.90x40x15 adjoint on trough
615      (what a pain)
616    
617    checkpoint57a_pre
618    o some modifs in tools/build_options for sunos
619    o call ctrl_pack for ctrl at end for optimcycle=0
620    
621    checkpoint57
622    o add horizontal bi-harmonic viscosity for vertical velocity
623      - new parameter viscA4W (defaults to viscA4)
624      - affects only non-hydrostatic code
625      - to be done: no-slip lateral boundary conditions
626    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
627    o implement Implicit Vertical advection for pTracers
628    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
629      (implemented also for implicit vertical diffusion & advection)
630    o OBCS: extend application of tracer open boundary conditions
631      to a strip beyond the boundary of width Olx/Oly
632    o add call monitor to TAF set of required calls (flow directives)
633      and include in natl_box_adjoint
634    o untangle a few ifdefs related to cost, ctrl, autodiff
635      untangel a few ALLOW_ECCO_OPTIMIZATION
636    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
637      (theta2, salt2 in ecco_cost_weights)
638    
639    checkpoint56c_post
640    o OBCS as control variables
641      - update ctrl_ad_diff.list, obcs_ad_diff.list
642      - remove balance of obcs controls from default
643      - fix index bug nobcs in ctrl_init
644      - fix dummy fields filen in ctrl_pack
645      - add dummy weights for obcs
646    o lsopt: comment out fort.94 output
647    o optim:
648      - remove unnecessary header files
649      - adjusted namelists
650      - add xerbla.F to Makefile
651    o exf:
652      - multiple modifications of exf_check_range
653      - unit change in exf_init_runoff from [m/year] to [m/s]
654    o mdsio:
655      - i/o-vector change debugLevel from debLevA to debLevB
656    
657    checkpoint56b_post
658    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
659      is called from DO_THE_MODEL_IO
660      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
661      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
662      - clean up PTRACERS_WRITE_TIMEAVE a little
663    o add another verification experiment that tests both the cfc-pkg and
664      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
665      reactive tendencies treated inline with regular timestepping
666    o testreport previously did a lousy job of comparing small numbers, so
667      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
668      implemented in the little c-progam tmp_cmpnum.c which is embedded in
669      testreport.
670    o ptracers_monitor: bug fix for MPI
671    
672    checkpoint56a_post
673    o GCHEM: finish reorganizating the package
674      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
675        (introduces another 3D-array for each passive tracer, but only if
676        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
677        gchemTendency is not needed because the timestep is done separately)
678      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
679      - GCHEM is now---more or less cleanly---separate from PTRACERS
680      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
681        so clear to me how that should be done in a general way.
682    o CFC: improve formatting of output in CFC_ATMOS
683    o PTRACERS:
684      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
685        that ALL experiments with ptracers enable can be checked. This makes
686        GCHEM_MONITOR obsolete.
687      - include a runtime parameter PTRACERS_monitorFreq that defaults to
688        monitorFreq
689      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
690    o add PTRACERS (PTR0[1-5]) to testreport output
691    o exf_check_range:
692      * default changed to .TRUE.
693      * will check values for niter0 if debLevA, every timestep if debLevB
694      * STOP in exf_check_range if 'out of range'
695      * range chosen generous to allow for potential extema
696      TBD: a version with stricter range
697           permitted range would be runtime parameters
698    o GMredi:
699      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
700      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
701      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
702    o GCHEM:
703      - move call to GCHEM_FORCING_SEP, so that it is now called before
704        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
705      - introduced a useGCHEM runtime flag and applied it everywhere.
706      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
707        this flag is now only visible within GCHEM-pkg routines.
708      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
709        be replaced by a 3D array that is computed before thermodynamics; for
710        this, the tracer ID iTracer had to be included into the parameter list
711        of ptracers_forcing
712      - set up forward_step to call gchem_forcing, that will replace
713        gchem_forcing_int in ptracers_forcing
714      - cleaning up
715    o small cleaning of exch2: remove files that are also in eesupp/src
716    
717    checkpoint56
718    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
719    o mnc: cleanup "full" files--fixes out-of-memory problem
720    o ECCO-GODAE
721      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
722      * fully merged and updated from SIO code
723        windstress sign change affects
724        - exf_inscal_[u/v]stress
725        - sign of xx_tau[u/v] adjustments
726        - signs in cost_scat
727      * ctrl_get_gen: avoid update of tau[u/v] for first few days
728      * natl_box_adjoint updated and compressed
729      * 2-level checkpoint switch added
730        (tested in EXP. 1 of natl_box_adjoint)
731      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
732    o SVD
733      * first complete, non-hacked version for SVD calculations
734      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
735        performed via direct access files admtlm_vector.it????
736        (via ctrl_[un]pack)
737      * optimcycle is used for ARPACK iteration counter
738        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
739      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
740        and add linear transforms where necessary
741      * controls are initial/final SST, SSS (can be extended; need to check
742        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
743    o mdsio: filename info to both stderr, stdout
744    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
745      from sign change
746    
747    checkpoint55j_post
748    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
749      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
750    o add consistent build directories and .cvsignore files to verification
751    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
752    o make all subroutines 30 or less characters in length for certain older
753      compilers to work (a thorough search only turns up two routines in
754      pkg/ptracers)
755    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
756      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
757    
758    checkpoint55i_post
759    o change arrays for total vertical diffusivity (2.D if explicit,
760      3.D if implicit) ; each ptracer uses its own background value.
761    o added mnc/NetCDF output capability to ocn_compon_interf
762      - added bits to verification/cpl_aim+ocn so that it can run on
763        ITRDA and other clusters without the mpirun "-wd" option
764    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
765      configuration
766    o give MNC the ability to create additional files rather than
767      exceeding a specified file size limit "MNC_MAX_FILESIZE"
768      - the default is just less than 2GB which is a practical limit
769        on many systems
770    o Compute the non-local term using either KPP vertical diffusivity (=default)
771       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
772    
773    checkpoint55h_post
774    o add verification test "vermix"
775    o remove all the *_ioinc flags and replace with the single global
776      outputTypesInclusive flag
777    o allow to set a vertical profile of vertical diffusivity for T & S
778    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
779    o useMNC moved from data.mnc to data.pkg
780    
781    checkpoint55g_post
782    o Renaming carbon AD experiments to comply with testreport conventions
783    o Updating adjoint of Held-Suarez hs94.1x64x5
784    o Fixing directives for non-ECCO forward_step, after ECCO directives
785      have been fixed to avoid recomp. of do_oceanic_phys
786      Works well for global_ocean.90x40x15,
787      but recomp. issue remains for carbon
788    o Updating adjoint output for natl_box_adjoint after
789      pkg/ecco has been modified (see taga c55d_post)
790    
791    checkpoint55f_post
792    o rename to timeave_init_fixed
793    
794    checkpoint55e_post
795    o some delicate re-shuffle of store directives to avoid one
796      extra call of do_oceanic_physics
797      affects ecco_the_main_loop.F, do_oceanic_physics.F
798      checkpoint_lev1_directives.h
799    o NB: this may break global_ocean adjoint temporarily,
800      but it is clear how to fix it. Will do later, need this now.
801    
802    checkpoint55d_post
803    o ECCO specific cost function terms (up-to-date with 1x1 runs)
804    o ecco_cost_weights is modified to 1x1 runs
805    o modifs to allow observations to be read in as
806      single file or yearly files
807    o enable to read exf forcing fields as either
808      single file or yearly files (flag useExfYearlyFields)
809    checkpoint55d_pre
810    
811    o switch between 2-level and 3-level checkpointing
812    o add ability of MNC to write local and "partial" (eg. 2D slices where
813      the full 3D field is never actually stored) arrays to NetCDF files
814      with the correct (that is, the complete multi-dimensional) set of
815      array indicies
816      - used in mom_vecinv() to write the diagFreq output
817      - tested (demonstrated) in verification/aim.5l_cs
818    o further mnc-ification
819      - add verification/lab_sea to the list with mnc setups
820      - fix undefined mnc v-names in cd_code
821      - add kpp to mnc output (both snapshot and timeave)
822    o non-hydrostatic code
823      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
824        in calc_gw.F
825      - defaults to viscAh
826      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
827        friction or Leith) in non-hydrostatic mode, as long as there is
828        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
829    o pkg/cost
830      extend simple cost functions to treat time mean quantities
831      (T,U,V) via cost_accumulate_state from cost_tile
832    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
833        be 2 times larger than the minimum size the advection scheme requires.
834        now get a perfect conservation of salt in advect_cs test-exp (updated)
835    o GGL90 (Gaspar's TKE mixed layer)
836      - add horizontal diffusion of TKE, requires exchanges in
837        do_fields_blocking_exchanges, horizontal diffusivity is zero by
838        default. In OPA there is no horizontal diffusion of TKE but the
839        mixing coefficients are computed from a horizontal average of TKE of
840        6 points or so. I think that diffusion has a little more physical
841        justification.
842      - clean up ggl90_calc in the hope of reducing memory usage (this hope
843        was in vain)
844      - mask tke-variable in ggl90_init
845    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
846    o fix biharmonic diffusion on CS-grid.
847    o more obcs stuff
848      - added obcs_external_fields_load as an alternative to the EXF-pkg option
849        for reading boundary values. This routine is called from
850        obcs_prescribe_read
851      - updated obcs_check
852      - changed sponge layer relaxation parameter units for days to seconds
853      - turned off sponge layer by default
854      - changed argument list of OBCS_CALC to myTime+deltaTclock
855      - fixed about 35 bugs in obcs_external_fields_load
856    
857    checkpoint55c_post
858    o obcs stuff
859      - new runtime flags useOBCSprescribe, useOBCSbalance
860      - re-arranged obcs_calc
861      - moved exf_getobcs to obcs_prescibe_read
862        obcs_prescibe_read is called after ORLANSKI stuff
863        and independent of it (executable can contain all).
864      - updated obcs_check
865      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
866        These may be necessary only if tangential velocities are
867        prescribed at OB, not sure, needs testing.
868    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
869      which simplifies the calls and passes the ifc check-bounds test
870    
871    checkpoint55b_post
872    o add a 2D scalar, Z location, exchange_2 routine.
873    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
874      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
875      affects advect_cs results (for the wrong reason): update output.txt
876    o use a more standard discretization for biharmonic viscosity ;
877     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
878      affects results of dome set-up: update output.txt
879    o fix gad_advection.F (CubedSphere part), back to version 1.23
880    o fix bug in mom_vi_del2uv.F (CubedSphere part).
881    
882    checkpoint55a_post
883    o merged code to
884      * prescribe/read time-dependent open boundaries
885        (works in conjunction with exf, cal)
886      * sponge layer code for open boundaries
887      * each boundary N/S/E/W now has its own CPP option
888        (healthy for the adjoint)
889    
890    checkpoint55
891    o up-to-date adjoint of previous breaks
892      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
893      - global_ocean_ebm: adjoint still needs fix (TLM ok)
894      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
895      - carbon: * remove tr1-related adjoint verification
896                * add ptracer as control variable
897    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
898      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
899    
900    checkpoint54f_post
901    o in verification/carbin/ remove experiment related to
902      ALLOW_PASSIVE_TRACER (array tr1 etc)
903      code_ad/ input_ad/ results_ad
904    
905    o add two new packages
906      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
907        + subject to optimization (memory)
908      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
909        + subject to reordering (many GOTOs in the original code)
910        + so far opps is called for every (i,j) point, and then operates in
911          the vertical; one may want to reorder the scheme in order operate in
912          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
913          fields)
914    o overhaul of IO so that we now have flags for MDSIO and/or MNC
915      - all verification tests compile and run with linux_ia32_g77
916      - defaults are compatible with current input files--nothing
917        should change if you were not previously using MNC
918      - MNC output has been added in numerous places (eg. timeave)
919        but there are still a few writes not yet do-able with MNC
920        (this is in progress)
921      - flags now allow for either/or/both use of MDSIO and MNC and
922        documentation will soon follow
923      - numerous small formatting cleanups for ProTeX
924    o add version info (via BUILD_INFO.h) to MNC and stdout
925    
926    checkpoint54e_post
927    o add two new packages
928      - pp81 (Packanowski and Philander, 1981), Richardson number and
929        stratification dependent mixing
930      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
931      - these scheme operate in a similar manner as KPP (without ghat, of
932        course), however there is only one diffusivity that is used for both
933        temperature and salinity (and passive tracers)ç
934    o add offline package
935    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
936      provided by Stephanie Dutkiewicz
937    o genmake2: add ability to search for C compilers and cleanup test output
938      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
939    
940    checkpoint54d_post
941    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
942    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
943      leading to additional shift by 5 days each year of integration
944       (i.e. leading to considerable offset over the years)
945    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
946    o start with no AB and no initial filtering (staggerTimeStep):
947      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
948    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
949      (external loading & cpl import/export stay in forward_step.F)
950    o update coupling interface to work with new staggerTimeStep
951    o change MDSIO ptracers_pickup.
952    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
953    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
954    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
955    
956    checkpoint54c_post
957    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
958      this affects (truncation error) output.txt of test-exp:
959       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
960    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
961    o change Qnet to always be the net heat flux, (+upward).
962      affects (truncation error) output of natl_box exp.: updated
963    o define the max number of passive tracers in PTRACERS_SIZE.h
964    o start to test mnc routinely in exp0
965    o add sea-ice loading (sIceLoad) as a new forcing field.
966    
967    checkpoint54b_post
968    o add testreport "-j JOBS" option for parallel builds (tested and pretty
969       impressive on Altix and Opteron systems)
970    o diagnostics can now write NetCDF files through the mnc package
971    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
972    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
973    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
974      affects (truncation error) output of lab_sea & natl_box exp.: updated
975    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
976    
977    checkpoint54a_post
978    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
979    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
980    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
981    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
982      + internal_wave (shift in writing cg2d_ini_res)
983    checkpoint54a_pre
984    
985    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
986      - modified verification/lab_sea and natl_box_adjoint accordingly
987    
988    checkpoint54
989    checkpoint53g_post
990    o prepare splitting of thermodynamics: store convect.counter in common block
991    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
992      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
993    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
994    o new parameter "nShapS": allow to treat differently S from T (nShapT)
995    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
996    o restore adjointability
997    
998    checkpoint53f_post
999    o modifications that affect AIM experiment results (update output.txt):
1000      - no advection of S at top interface Nr (pkg/generic_advdiff)
1001      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1002    o AIM pkg:
1003      - include stability function into surf.Flux derivative relative to Tsurf
1004      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1005    
1006    checkpoint53e_post
1007    o merged cylindrical coord configuration
1008    o added rotating_tank experiment
1009    checkpoint53e_pre
1010    
1011    checkpoint53d_post
1012    o faulks upgraded: re-generate output.txt that have changed:
1013       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1014    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1015    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1016    o added Sadourny discretization of Coriolis
1017      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1018      - re-enabled use of omega3 (useAbsVorticity)
1019    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1020      vector-invariant equations
1021      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1022    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1023      hopefully without new bugs
1024      - still to do: biharmonic friction for non-hydrostatic w
1025    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1026    o regenerated output for global_ocean_ebm (using -ieee)
1027    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1028      of mom_common/
1029      - simple re-arrangement of instructions within computing loop
1030    checkpoint53d_pre
1031    
1032    checkpoint53c_post
1033    o new version of coupler for AIM+thSIce and Ocean models
1034     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1035     - land: change Evaporation of snow
1036     - aim with thSIce: fix bug in snow-precip.
1037    o changes to calc_gw.F
1038     - bug fix for w^2 term near the bottom boundary
1039     - (hopefully) improve the lateral slip boundary condtions for use with
1040        partial/looped cells
1041      - because the bug fix changes two verification experiments anyway (exp5
1042        and plume on slope), change the lateral boundary condition from half slip
1043        to the value of no_slip_sides
1044    o ebm package wasnt quite up to the parallel task. Fixed that.
1045    o Adjoint of EBM package + verification
1046      * TLM OK
1047      * ADM not sufficient accuracy yet (needs further testing)
1048    
1049    checkpoint53b_post
1050    o Commiting new energy balance model to repository
1051      * package is pkg/ebm
1052      * verif. is verification/global_ocean_ebm
1053      * references are in ebm_driver.F
1054    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1055    C        Global thermohaline circulation. Part I:
1056    C        Sensitivity to atmospheric moisture transport.
1057    C        J. Climate 12(1), 71-82
1058    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1059    C        Global thermohaline circulation. Part II:
1060    C        Sensitivity with interactive transport.
1061    C        J. Climate 12(1), 83-91
1062    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1063    C        Destabilization of the thermohaline circulation
1064    C        by atmospheric eddy transports.
1065    C        J. Climate 7(12), 1870-1882
1066    o Will need long integration testing.
1067    checkpoint53b_pre
1068    
1069    o created pkg/mom_common in preparation for variable viscosity code
1070    o renamed and split ini_mnc_io
1071    o pkg/land: only liquid water can diffuse or run-off
1072    o AIM using land: soil wetness availability account for snow
1073    o added printMapIncludesZeros to EEPARMS namelist
1074    
1075    checkpoint53a_post
1076    o restore TAMC compatiility for exf_constants.h
1077      (no usage of _d in .h)
1078    o Additional storing in KPP in an attempt to fix
1079      TAMC problem with adjoint of KPP code.
1080      (no success...)
1081      Identical code works fine with TAF.
1082    o Fixed verification/natl_box_adjoint experiments.
1083      Initial conditions for Experiments 4 and 5 are now
1084      set to "SEAICE_initialHEFF=0", which is more reasonable,
1085      and hence gives results closer to that of Experiment 2.
1086      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1087    
1088    checkpoint53
1089    o stable checkpoint with up to date adjoint
1090      TLM tests only run for 1st grdchk at the moment. Its unclear if
1091      this is a code problem or a problem with resetting code for g_
1092      variables that is being autogenerated wrong.
1093      Otherwise:
1094       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1095       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1096         are both still in chaos following their security messes.
1097    
1098    checkpoint52n_post
1099    o various build (mostly genmake2) changes including:
1100      - ability to build/run more easily within Cygwin and MacOS X
1101      - more complicated Makefiles with a stronger dependence on Gnu Make
1102    o pkg/seaice modifications
1103      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1104        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1105        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1106      - changed proxy for geostrophic velocity and updated
1107        verification/lab_sea/results/* accordingly
1108      - removed ADI dynamic solver from pkg/seaice
1109      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1110        they caused a segmentation fault under certain circumstances
1111      - removed unused field WATR
1112    o bug fix in exf-package:
1113      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1114         now reflect that.
1115    o small fixes in the cal-package:
1116      - set reference date to first of January for the 'model'-calendar
1117      - failing of cal_CheckDate in cal_FullDate now actually results in a
1118        warning
1119    o small modifications in exf-package to increase flexibility:
1120      - change climtempfreeze from a constant to a runtime parameter that
1121        is specified in data.exf_clim (default = -1.9)
1122      - introduce runtime parameter windstressmax (default = 2.0) that is
1123        specified in data.exf
1124    o fix in pkg/thsice:
1125      - update Evap (Tsf changes) to be consistent with Latent heat flux
1126      - maintain snow precipitation unchanged (even if Tsf >=0).
1127     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1128    
1129    checkpoint52m_post
1130    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1131      this does not change any of the results, because myIter=0 in swfrac always
1132      lead to jwtype=2 (the default anyway), but the call makes little sense
1133      as a default
1134    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1135    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1136      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1137    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1138    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1139    o extending useSingleCpuIO option to work with new exch2 I/O format
1140      - old-style, missing-tile I/O is still accessible by defining CPP
1141        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1142    o monitor package can write to NetCDF files and/or STDOUT
1143    o fix re-definition bug in MNC_GRID_INIT_ALL()
1144    o doc/api_reference added
1145      - a framework for building an API Reference Manual using all
1146        the "protex" comments embedded in the code
1147      - see pkg/generic_advdiff, pkg/mnc for examples
1148    o MNC:
1149      - make myThid the last argument for all subroutines
1150      - new default for the grid files: NO halos
1151      - add useMNC and other run-time flags
1152      - separate per-file-group handling of the unlimited dimension
1153      - early initialization of MNC w/ flags read at the eeboot stage
1154        and lookup tables set in initialize_fixed
1155      - write all MNC output to a freshly-created directory
1156    o thermodynamics sea-ice (thsice) is now tested with testreport.
1157    o test exp. advect_cs: use the standard cs32 grid ; update output.
1158    o Added functionality to grdchk:
1159      pick global i,j,k position (or nearest wet) where to perform check.
1160    
1161    checkpoint52l_post
1162    o new land formulation:
1163      a) use ground enthalpy as prognostic variable to ensure exact
1164         energy conservation.
1165      b) account for water temperature and for latent heat of freezing
1166         in all processes (rain, run-off, ground storage)
1167      c) compute surface and ground temperature implicitly.
1168    o aim_v23 modification for new land model:
1169      a) Treat separately land / ocean / sea-ice surface fluxes
1170         to allow implicit computation of land & sea-ice surface temp.
1171      b) add snow precipitation.
1172    checkpoint52l_pre
1173    
1174    o fix problem (when 1 tile is empty) in min/max monitor.
1175    o fix bug in timeAve (u,vZetatave in common block)
1176    o no restoring terms under ice for pkg/seaice
1177    o moved SEAICE_DO_DIAGS to S/R do_the_model_io

1179    o change MNC call locations and add coordinate attributes
1180    o mask vorticity at the corner ; affects global_ocean.cs output
1181    o fix ini_curvilinear_grid ; test CS experiments with mpi
1182    o aim.5l_cs: modify sea-ice fraction input file ; update output
1183    o exf: Adding simple range check routine for exf fields after read
1184    
1185    checkpoint52k_post
1186    o removed top-level directory "diags"
1187      - we migrated these functions to pkg/timeave a long time ago
1188    o fixed bug introduced in pkg/monitor
1189    o accuracy ctrlprec = 32 insuffient for gradient checks using
1190      averaged fields (I/O via cost_averages)
1191      -> use ctrl.h in active_file*.F to control I/O precision.
1192    o paramter list of CALL ADTHE_MAIN_LOOP
1193    o added initial do_the_model_io to ecco
1194    o set all ...Freq to zero after cost_final
1195      taveFreq, dumpFreq, pChkptFreq
1196    o MAIN and ECCO differentiability restored
1197    
1198    checkpoint52j_post
1199    o fix nchklev in tamc.h for global_ocean...
1200    o Bringing flow and store directives up-to-date
1201    o Really weird thing!
1202      call do_the_model_io from the_main_loop with parameters
1203      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1204      TAF places a faulty re-call of initialise_varia
1205      after cost_final call which should not be there!
1206    checkpoint52j_pre
1207    
1208    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1209      error messages
1210    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1211    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1212      debug output
1213    o modfied mdsio_writefield.F to handle non-global files under exch2
1214    o update AIM Cubed-Sphere exp (aim.5l_cs):
1215      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1216    o update AIM Equatorial Channel exp:
1217      use standard aim_v23 pkg and change the SST fields to be more realistic.
1218    o globalFile now works with exch2
1219    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1220      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1221    o limit timeave output for hi-res integrations
1222    
1223    checkpoint52i_post
1224    o removed CPP_EEOPTIONS.h from verification/*/code
1225    o updated the tiling for global_ocean_pressure
1226    checkpoint52i_pre
1227    
1228    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1229      the old pkg/aim).
1230    
1231    checkpoint52h_pre
1232    o shortened offending lines in exch2_send_rx?.template
1233    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1234    o genmake2: add build & execute test for NetCDF code
1235    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1236      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1237    o added useSingleCPUIO flag to monitor.F and mon_out.F
1238    o added temporary hack for sea-ice dynamics on the cube:
1239      metric terms are ignored and it is assumed that
1240      there is no sea-ice on cube faces 1, 2, 4, and 5.
1241    
1242    checkpoint52f_post
1243    o added exch2 cube routines to pkg/exch2
1244    o modified hs94.cs-32x32x5 to use it
1245    o added new grid files to hs94.cs-32x32x5
1246    checkpoint52f_pre
1247    
1248    checkpoint52e_post
1249    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1250      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1251    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1252      to work with implicit vertical advection and AB ;
1253    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1254    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1255     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1256    checkpoint52e_pre
1257    
1258    o fix bug in impldiff when Nr=1 or Nr=2.
1259    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1260    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1261    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1262      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1263    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1264    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1265    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1266    
1267    checkpoint52d_post
1268    o re-tiled many expts to allow comparison in multi-processor mode
1269      - updated output accordingly
1270      - changed hs94.128x64x5 to use intial T from file rather than use the
1271        random number generator
1272    o add infrastructure in model routines for fizhi and gridalt packages
1273    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1274    o changes to permit hi-res, cubed-sphere, configuration
1275      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1276      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1277      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1278        of surface winds for the cube
1279      (A verification experiment, based on global_ocean.cs32x15, but with
1280       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1281       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1282       complete with example surface forcing files and matlab scripts to look
1283       at the output and compare it with that of global_ocean.cs32x15.)
1284    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1285       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1286       to conform to the common rule.
1287    o check-in the first version of the coupler + interfaces for multi-components
1288       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1289       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1290       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1291       - ocean and atmos. share the same horizontal grid (no interpolation).
1292       - exchanges between component and coupler is done in forward_step
1293    o new verification experiment, cpl_aim+ocn:
1294       coupled ocean - AIM atmosphere on cs32 grid.
1295    
1296    checkpoint52d_pre
1297    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1298    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1299    
1300    checkpoint52c_post
1301    o Fixing OPTIONS files for use of exf:
1302      - ALLOW_ECCO not needed
1303      - ECCO_CPPOPTIONS.h should not be included from
1304        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1305        as has been the case in the past
1306      - All cal/exf related options are currently set in
1307        single header file. Should remain so until we
1308        agree on a consistent new policy.
1309    o Removed all CPP options for cal package.
1310      cal has no more CPP options.
1311    o modified STOREs in GAD_ADVECTION
1312    o corrected key comp. for passkey
1313    
1314    checkpoint52b_post
1315    o new version: "thsice" of thermodynamic sea-ice pkg:
1316     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1317     - modify fluxes but do not change theta directly;
1318     - light cleaning of bulk_force pkg (still needed with thsice).
1319     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1320       + output_thsice.txt to test thsice & bulk_force pkgs.
1321    o put back grid & coriolis monitor output.
1322    checkpoint52b_pre
1323    
1324    o call "do_the_model_io" at the beginning (=> dump initial state)
1325    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1326    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1327      (need info on NUMBER_OF_PTRACERS)
1328    o missing PTRACERS headers in some routines
1329    o default tamc.h in pkg/autodiff supposed to crash
1330      to ensure proper customization
1331    
1332    checkpoint52a_post
1333    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1334      - moved surfaceTendencyTice from pkg/seaice to main code
1335      - subroutine FREEZE_SURFACE now limits only surface temperature
1336        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1337        => new output.txt for global_ocean.cs32x15 & global_with_exf
1338      - keep the old version of FREEZE for backward compatibility;
1339        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1340      - corresponding modifs for TAF directives
1341    o added surface flux output variables to TIMEAVE_STATVARS
1342    o time-averaged output for pkg/ptracers
1343    o fix problem with ECCO-related divided adjoint
1344      snapshot file was missing some ad-variables,
1345      but no warning issued by TAF
1346    
1347    checkpoint52a_pre
1348    o some bug fixes for #undef REAL4_IS_SLOW
1349    
1350    checkpoint52 = ecco_c52_e35
1351    o after testing adjoints of checkpoint51u_post
1352    
1353    checkpoint51u_post
1354    o this is the post-merge tag of the ecco-branch
1355      (needs another clean checkout and re-testing)
1356    o various natl_box_adjoint configs and results
1357      but no input fields
1358    o obcs adjoint not yet merged!
1359    o adding ECCO global 1x1 and 2x2 degree configs
1360    o updated/extended some store directives for seaice
1361    o pkg/ecco now containes ecco-specific part of cost function
1362    o top level routines the_main_loop, forward_step
1363      supersede those in model/src/
1364      previous input data.cost now in data.ecco
1365      (new namelist ecco_cost_nml)
1366    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1367    
1368    checkpoint51t_post
1369    o this is the pre-merge tag of the ecco-branch
1370    
1371    checkpoint51s_post
1372    o cleanup: removed various obsolete #define-s
1373    o pkg/grdchk
1374      - renamed 'ph-grd 3' to 'grad-res'
1375      - merged from ecco-branch
1376        (remaining bug fixes for obcs gradient checks)
1377      - additional high-precision output for testreport
1378        (grep for 'precision_grdchk_result')
1379    
1380    checkpoint51r_post
1381    o cleaned up or removed CPP_OPTIONS.h files
1382    o updated results for some of the tests to reflect the new
1383      optfiles (-ieee: -O0 instead of -O3)
1384    
1385    checkpoint51q_post
1386    o cd_code:
1387      - moved cd_scheme.F -> cd_code_scheme.F
1388      - separate read_checkpoint from cd_code_ini_vars.F
1389      - separated cd_code part from write_checkpoint
1390      - updated AD_SOURCE, generated .flow
1391      - added CD_CODE_VARS.h to the_main_loop
1392      - Moving cd_code specific store dir.s to pkg/cd_code
1393    o ctrl package totally restructured
1394      - pack/unpack now optional and decoupled from
1395        xx_/adxx_ I/O
1396      - ctrl_pack/unpack cleaned
1397        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1398      - confined inclusion of AD_CONFIG.h to where necessary.
1399    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1400    
1401    checkpoint51p_post
1402    o create initial cd_code package
1403      - WARNING: the initialization of fields within packages
1404        is broken because INI_FIELDS (where READ_CHECKPOINT is
1405        called) is called *before* PACKAGES_INIT_VARIABLES.
1406        This seems to be backwards since
1407        1) its important to initially zero the entire field including
1408           the "halo" region
1409        2) zeroing needs to be done *before* reading pickup info
1410           and the pickup call might or might not happen in any
1411           particular run
1412      - this needs an overhaul for R2
1413    o cleanup verification/*/code/GMREDI_OPTIONS.h
1414    o cleanup testreport
1415    
1416    checkpoint51o_post
1417    o bringing AD-related verif's up to date with genmake2

1419      - global_ocean.90x40x15/
1420      - hs.94.1x64x5/
1421      - (front_relax/ )
1422    o (more) consistent directory structure for AD-related verif.'s
1423    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
1424    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1425    o bug fix in find_alpha.F for MDJWF:
1426      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1427        change rho -> rho-rhoConst
1428      - replace call find_rho to find_rhonum
1429    o initialisation of rFlx extended to full array (required by TAF)
1430      and shifted to thermodynamics
1431    o removed PTRACERS.h in ptracers routine
1432    o added surfacetendencyPtr to S/R parameter list pracers_forcing
1433    o Correcting initialisations for fVerU, fVerV.

1437    checkpoint51o_pre
1438    
1439    o undid all of cp51 pending some cleanups and discussion
1440    o added the [#include "AD_CONFIG.h"] statement to all files that need
1441       it for adjoint/tl #defines
1442     o re-worked the build logic in genmake2 to support AD_CONFIG.h
1443     o removed tools/genmake since it no longer works
1444    
1445    checkpoint51n_post
1446    o modifications to make FREEZE flux visible to pkg/kpp
1447      - moved surfaceTendencyTice from pkg/seaice to main code
1448      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1449      - subroutine FREEZE now limits only surface temperature
1450        (this means new output.txt for global_ocean.90x40x15,
1451         global_ocean.cs32x15, and global_with_exf)
1452    o added surface flux output variables to TIMEAVE_STATVARS
1453    
1454    checkpoint51n_pre
1455    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
1456    o added [#include "AD_CONFIG.h"] to all files that use the following
1457      defines:

1460      - ALLOW_ECCO_OPTIMIZATION
1461    
1462    checkpoint51m_post
1463    o incorporating changes to get TAMC/TAF working in genmake2
1464      - added new TAMC/TAF targets to the Makefile
1465      - various cleanups related to package handling
1466      - these changes should have no impact on the forward model
1467    
1468    checkpoint51l_post
1469    o changes to pkg/cal and pkg/exf that allow and speed-up long integrations
1470     - faster algorithm for cal_addtime.F
1471     - higher precision arithmetic, where needed
1472     - pkg/exf *startdate variables changed from calendar date to
1473       model integration time
1474    
1475    checkpoint51l_pre
1476    o add salt flux to forcing fields (used when salty sea-ice forms or melts)
1477    o enable to apply restoring on S & T only in a latitude band.
1478    o update output (external_forcing_surf modif. change truncation errors)
1479       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
1480    
1481    checkpoint51k_post
1482    o change default to: useNHMTerms=.FALSE.
1483     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
1484       adjustment.128x64x1, aim.5l_Eq_Ch, aim.5l_LatLon, hs94.128x64x5, hs94.1x64x5
1485     - new output.txt for idealized oceanic exp (NHMTerms are now turned off):
1486        exp1, ideal_2D_oce
1487     - change data file of oceanic exp (leave the results unchanged for now)
1488       exp2, global_ocean[90x40x15,pressure,with_exf], lab_sea, natl_box
1489    o set gravitySign automatically according to the vertical coordinate used
1490      (and change sign: back to "logical" value: +1 when R increases downward)
1491    o added an include barrier to the default CPP_OPTIONS.h and
1492      removed the #include "PACKAGES_CONFIG.h" from it
1493    o fix a bug in mom_fluxform (from chk51j_post)
1494

1579      - debLevB: equivalent to current debugMode=.TRUE.
1580    o introducing pathname variable mdsioLocalDir for mdsio
1581      that can be specified at runtime
1582      (relevant for cluster I/O to local disk)
1583    `
1584    >>>checkpoint51b_post
1585    adjoint of ptracers

1591    o made ptracers_forcing same as external_forcing_s
1592    o added verification for adjoint with ptracers
1593      - adm. grdchk fail so far
1594      - tlm. grdchk OK
1595      - checked tapelev/comlev recomputations: OK
1596    <<<checkpoint51b_pre

1604    
1605    checkpoint51
1606    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1607      - autodiff, ctrl, exf, grdchk, seaice
1608      kept separate packages
1609      - cost, ecco, obcs
1610    o updating verification/internal_wave, verification/lab_sea
1611      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1612    
1613    checkpoint50i_post
1614    o Preparing next differentiable checkpoint and sync
1615      of MAIN vs. ecco-branch
1616      - 1st step: this one is differentiable
1617      - 2nd step: next(! not this) checkpoint will have updated packages
1618                  from ecco-branch)
1619    
1620    checkpoint50h_post
1621    o new package "land": provide surface BC for AIM.
1622    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1623    o AIM: use true log-P extrapolation for near surface temp (= as in
1624        F.Molteni paper) ; update aim.5l_cs output.
1625    o New variable in PARM03 for more flexible pickups
1626    o somewhat cleaned package initialisation sequence for
1627      ctrl/ cost/ ecco/ in packages_... routines
1628    
1629    checkpoint50g_post
1630    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1631      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1632      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1633        made the default because of faster convergence than ADI
1634    
1635    checkpoint50f_post
1636    o exf totally restructured
1637      - replaced all exf_set_ routines by one generic exf_set_gen.F
1638        and made sure it's still differentiable
1639      - split exf_getffields.F into new exf_bulkformulae.F
1640      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1641      - updated adjoint/makefile and relevant verif. accordingly
1642    
1643    checkpoint50f_pre

1652    
1653    checkpoint50e_post
1654    o make KPP work with PTRACERS
1655     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1656       nearly a copy of kpp_transport_s
1657     - there is no analogue to SurfaceTendencyS, so I have to use
1658       gPtr(of the surface layer) instead
1659    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1660    checkpoint50e_pre
1661    
1662    checkpoint50d_post
1663    o change kpp output from multiple-record state files to single-record state
1664      files analogous to write_state.F
1665    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1666      analogous to the cg2d-related output.
1667    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1668      so that writing to internal file fn (with length 512) fails.
1669    checkpoint50d_pre
1670    
1671    checkpoint50c_post
1672    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1673    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1674    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1675    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1676    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1677    
1678    checkpoint50c_pre
1679    Merging from release1_p13:
1680    o bug fix for pkg/seaice dynamic solver
1681    o Added SEAICE_initialHEFF to pkg/seaice
1682    
1683    checkpoint50b_post
1684    o store u*,v* in gU,V instead of in guNm1,gvNm1
1685    o in order to put the momForcing out of the Adams-Bashforth:
1686      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1687      to timestep.F
1688    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1689    o re-generate output for highly sensitive test-exp:
1690       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1691    
1692    checkpoint50b_pre
1693    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1694    o corrected CPP option mismatch in exf_Bulk... functions for case
1695      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1696    
1697    checkpoint50a_post
1698    o Bug fix for merging between c50 and KPP.
1699      ikey was passed from thermodynamics to kpp_calc via
1700      common block rather than being recomputed in kpp_calc,
1701      in contradiction with new key itdkey.
1702      New key ikppkey created, and tamc.h headers updated.
1703    
1704    checkpoint50
1705    - 2nd step of merge with ecco-branch:
1706      merge changes in ecco-branch back into main trunk
1707    - bug fix in find_alpha
1708    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1709    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1710    - merged some sliced AD support routines
1711    
1712    checkpoint49
1713    merged from ecco-branch:
1714    o exf:
1715      - Enable initialisation of forcing fields to constant
1716        (runtime) values.
1717      - in exf_getffields.F
1718        Reduce i-/j-loop to interior domain, discarding overlaps.
1719        That also fixes wrong TAF-key computations for key_1, key_2
1720        with bulf formulae.
1721      - exf_init.F modify #ifdef for exf_init_evap
1722      - exf_getffieldrec.F, ctrl_getrec.F
1723        The following INT-usages are not safe:
1724          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1725          fldcount = int(fldsecs/fldperiod) + 1
1726        and were modified.
1727    o autodiff: checkpoint_lev...
1728      - updated storing for bulk formulae (some arrays were missing)
1729      - added state for seaice package
1730      - synchronized with main branch
1731    o DIVA:
1732      Modif.s in
1733      - the_main_loop.F
1734      - the_model_main.F
1735      and added cost_final_restore.F cost_final_store.F
1736      o With these changes, it is possible to fully separate
1737        the first forward run to compute the cost function (mdthe_main_loop)
1738        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1739        into separate model executions.
1740        This enables better tuning of DIVA to given queue sizes.
1741      o Loss of cost function value in consecutive DIVA runs is
1742        fixed by storing to 'costfinal' file.
1743      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1744        beginning/end of adjoint integration is accounted for.
1745      The current changes apply to TAF-1.4.26.
1746      TAF has one remaining bug, requiring one manual change
1747      (see MITgcm manual).
1748    o cal: synchronized between MAIN and ecco-branch
1749    
1750    checkpoint48i_post
1751    o Changes to restore differentiability of code w.r.t. previous tag
1752      (mostly adding new routines to make list and replacing
1753      pressure by totPhiHyd).
1754    o Updated and merged grdchk package
1755      - has both ADM and TLM checks
1756      - works for single- and multi-proc.
1757      - output cleaned
1758      - worked successfully for parallel DIVA
1759    o genmake:
1760      - Adding -platform=SP4
1761      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1762    o Modif. for DIVA:
1763      ctrl_unpack should not be called in intermediate DIVA interval.
1764      (similar thing would apply for active files such as
1765      tbar, sbar, psbar, which should not be reinitialised;
1766      only relevant for ecco-branch)
1767    
1768    checkpoint48h_post
1769    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1770    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1771    o Added SEAICE_initialHEFF to pkg/seaice
1772    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1773    
1774    checkpoint48g_post
1775    --- EOS:
1776    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1777      store total Potential in totPhyHyd for diagnostics & EOS.
1778    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1779    --- Pressure/geopotential gradient:
1780    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1781    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1782      ( changes results of global_ocean_pressure )
1783    o NLFS + z-coord.: add eta*Rho' contribution.
1784    o accurate phiHyd when using interface-W at the middle between 2 centers
1785     ( changes results of ideal_2D_oce )
1786    o includes r* 2nd term in potential gradient.
1787    
1788    checkpoint48f_post
1789    Merging from release1_p12:
1790    o Modifications for using pkg/exf with pkg/seaice

1796      (SBO) core products, including oceanic mass, center-of-mass,
1797      angular, and bottom pressure (see pkg/sbo/README.sbo).
1798    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1799      to avoid negative values in shallow regions.
1800      - updated verification/natl_box/results/output.txt
1801      - updated verification/lab_sea/results/output.txt
1802    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1803    o Added useSingleCpuIO option (see PARAMS.h).
1804    o Updated useSingleCpuIO option in mdsio_writefield.F to
1805      work with multi-field files, e.g., for single-file pickup.
1806    o pkg/seaice:
1807      - bug fix in growth.F: QNET for no shortwave case
1808      - added HeffFile for specifying initial sea-ice thickness
1809      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation

1811      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1812    o pkg/seaice:
1813      - adjoint-friendly modifications
1814      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1815    
1816    checkpoint48e_post
1817    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1818    o dynamics: change definition of computational domain & adapt mom_fluxform
1819      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1820    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1821        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1822        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1823        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1824        inverted_barometer solid-body.cs-32x32x1
1825      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1826    
1827    checkpoint48d_post
1828    o in preparation for r*:
1829     a) use pre-computed gradient of hydrostatic potential:
1830        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1831     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1832        => affects results of glob_oce_pressure (different truncation error)  
1833      update output.txt of ideal_2D_oce & global_ocean_pressure
1834    
1835    checkpoint48d_pre
1836    o in preparation for r*:
1837      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1838      pass the 2 comp. of the grad. as arguments to momentum S/R.
1839      but for the moment, only used if it does not change the results.
1840    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1841    
1842    checkpoint48c_post
1843    Modifications in treatment of initial flux forcing controls
1844    to avoid extra storing of flux fields.
