5      ==============================      ==============================
6    
7    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
8      and trend from exf forcing and ctrl control adjustments
9    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
10      (since checkpoint57x_post)
11    o change the default rotation period to 86164.s = the Earth rotation
12    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
13      and based on a reference stratification. Tested within hs94.cs-32x32x5.
14    o seaice advection: add code for choosing between the default (2nd order
15      central differences) and multiDim advection schemes provided by
16      pkg/generic_advdiff
17    o seaice:
18      - removed all references to SEAICE_GRID.h fields from
19        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
20        (cubed-sphere configuration will change a little)
21      - grid computations in seaice_init are obsolete now.
22      - cleaned up code a little so that is easier to read (hopefully).
23      - added new (better?) discretizations of default advection and diffusion
24        (turn on with SEAICEuseFluxForm)
25      - replace 1 in 3d global fields by kSurface in growth.F
26      
27    checkpoint58a_post
28    o seaice:
29      - bug fix in advect.F
30    o shelfice:
31      - separate shelfice load anomaly from pload (breaks with time
32        dependent forcing), => introduce constant field shelficeLoadAnomaly.
33        Its default is 0., but it may be computed more cleverly from (unknown)
34        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
35        done offline. A good approximation of the pressure load anomaly is
36        necessary to avoid large initial adjustment processes underneath
37        deep-reaching shelfice.
38      - small fix in ISOMIP shelfice_thermodynamics
39      - add more sophisticated thermodynamics of Hellmer (1989), this is
40        now the default
41      - give a few constants more intuitive names
42    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
43      if bulk formulae are used in long integration (especially EmPmR). Turn
44      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
45      if balancePrintMean, the imbalance that is substracted is printed to
46      STDOUT.
47    o fix bug (typo) in obcs_apply_eta.F
48    o add a new package shelfice which enables us to model the circulation
49      underneath shelf-ice with draughts of hundreds of meters.
50     - works
51     - to do: + include improved thermodynamics
52              + check whether kSurfC (from model/inc/SURFACE.h) can be used
53                instead of new field kTopC
54              + can we use topoFile, Ro_surf and existing code in ini_depth.F
55                instead of new field R_shelfIce and new code in ini_depth.F
56                and ini_mask_etc.F?
57              + adjust vertical mixing schemes?
58    o seaice pkg:
59     - add a cpp-flag to include a simple formula for a salinity dependent
60       freezing point of sea water at the surface
61     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
62       meridional stresses are now different (and hopefully correct)
63    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
64       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
65       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
66    o pkg/diagnostics: add options and parameters for regional-statistics
67       diagnostics ; define regions by reading a region-mask from a file
68       (might add other options later)
69    o pkg/bulk_force:
70     - add option and parameters to use AIM surface-flux formulae.
71     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
72       others forcing fields (defined in PARM05, parameter file "data") are loaded
73       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
74     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
75     - use the right EXCH call for uwind,vwind (to work on CS-grid).
76     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
77       and parameters (note: calcWindStress replaces .NOT.readwindstress).
78     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
79    
80    checkpoint58
81    o add "--embed-source" option to genmake2 which, when the supporting
82      tools can be compiled (as determined by genmake2) will turn on the
83      embed_files package which then embeds the entire MITgcm source code
84      (*.[fFhc] + Makefile) used for the build within the executable
85      - requested by CNH but off by default
86      - adds a paltry <9MB to the mitgcmuv executable in most cases
87      - only writes the output when useEMBEDSRC in eedata is true
88    o clean up 3-dim. relaxation codes:
89      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
90      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
91      * Thanks to Tom Haine for testing!
92    
93    checkpoint57z_post
94    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
95      affects output (@ truncation level) of exp. plume_on_slope ; updated.
96    o fix the pickup behavior for obcs in combination with ptracers
97    o fix a bug in ptracers_external_fields_load
98    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
99      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
100    o transfered surface NH pressure to eta field (if exactConserv).
101    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
102         and update lab_sea output.txt file.
103    o completing 3-dim. relaxation code: additional term
104         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
105      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
106      * At compile time, in "EXF_OPTIONS.h" set
107          #define  ALLOW_CLIMTEMP_RELAXATION
108          #define  ALLOW_CLIMSALT_RELAXATION
109      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
110          tauThetaClimRelax3Dim = 15552000.0,
111          tauSaltClimRelax3Dim  = 15552000.0,
112      * 3 cases:
113          1) Use a constant-in-time 3-dim. field
114          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
115          3) Real-time relax. to time-evolving prescribed field
116    o Adding Laplacian-type smoothness constraint on
117      initial and boundary (forcing) controls (ic, bc)
118      * enable at compile-time via
119        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
120      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
121      * Absolute scale somewhat unclear so far
122      * no area weighting was included since no other cost term does so far
123    
124    checkpoint57y_post
125    First step for a NLFS adjoint
126    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
127    o new init. routines for calc_r_star, calc_surf_dr
128    o still need to deal with ini_masks_etc
129    o testreport seemed happy
130    checkpoint57y_pre
131    
132    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
133    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
134    o add new offset feature to offline pkg (plus minor cleanup)
135    o cfc fixes for final year of integration
136    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
137      be in GCHEM_OPTIONS).
138    
139    checkpoint57x_post
140    o fix testreport Pb in multiple test experiment.
141    o cleanup our namelist syntax in verification:
142      - make it more F95 standards compliant (some work still needed)
143      - allows the vast majority of our tests to work with gfortran
144    o Non-Hydrostatic:
145     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
146     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
147    o Allow to apply AB on T,S rather than on AB(gT,gS):
148     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
149     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
150       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
151     - need a "clever" read_pickup to restart from the other AB formulation
152    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
153    o remove some unused variables (reduces number of compiler warnings)
154    o adjoint
155      * Disable useVariableViscosity for adjoint for time being
156        (there are a number of extensive recomputations)
157      * Initialize certain variables needed for adjoint
158    
159    checkpoint57w_post
160    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
161                 fix the singleCpuIO RS version of MDSWRITEFIELD
162       and add a WARNING if using globalFiles=T with multi-processors.
163    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
164      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
165    o tracer advection scheme:
166      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
167       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
168       was not very convenient).
169      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
170       (further tests needed for the implicit DST & Flux-Limiter schemes).
171    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
172      and sRef for convenience, handy, when you want to initialize
173      ptracers in a large domain with a constant non-zero value. Also,
174      untangle ptracers_init.F a little.
175    
176    checkpoint57v_post
177    o change dome exp. to use variable viscosity in side-drag terms.
178    o remove all the files from the cfc_offline test since they are now
179      incorporated into tutorial_cfc_offline which has been producing
180      identical results for a few days of testing
181    o add new parameter: sideDragFactor to enable half-slip-side BC
182      and change side-drag S/R to use viscosity from mom_calc_visc
183      (can switch back by setting sideDragFactor=0.); affects results at
184      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
185       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
186    o vorticity & strain are now computed without masking, to account for
187      no-slip-side BC in variable viscosity calculation ; mask is applied
188      anyway later on, before computing advection/coriolis terms.
189    o modify exp4 to test new obcs support for reading from external files
190      and for passive tracers
191    o fix behavior of ptracers_monitor when monitor output is written to a
192      netcdf-file; still not independent of monitor.F (writes in the same
193      file).
194    o change default value of tRef (put a uniform, meaningful value for ocean
195      & atmos) and initialize sRef (was missing, as Martin mentioned).
196    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
197      to be proportional to enstrophy dissipation length.  Thus,
198       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
199      This is now consistent with Smagorinsky and with the manual.
200    
201    checkpoint57u_post
202    o OBCS and PTRACERS: add open boundary support for passive tracers
203      - either use homogenous (pseudo) v.Neumann conditions or prescribe
204        OB-values from file; this is not different from the way theta and salinity
205        are treated
206      - however, Orlanski-radiation conditions are not supported, and the model
207        will stop if you use pTracers and Orlanski at the same time.
208      - beefed up the rountine obcs_external_fields_load: now only those open
209        boundary values are overwritten with values from files for which there
210        are really files, otherwise the OB-fields remain untouched. This makes
211        it possible to use different OBs at different ends of the domain (as
212        with EXF)
213    o reduce number of exch calls in shap_filt (s2).
214    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
215      truncation level) 4/5 MLAdjust test results (11&12 digits match).
216    
217    checkpoint57t_post
218    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
219    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
220      same truncation, independent of the face number: affects affects several
221      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
222    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
223      note that biharmonic viscosity + no-slip was not tested in any experiment.
224    o fix bug in non-linear free-surf side-drag ; generate new output for
225      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
226    o make mnc honor the writeBinaryPrec flag for most kinds of output
227    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
228    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
229      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
230    o add brackets in multi-terms sum to get same truncation, independent of
231      the face number (manage to get exactly same value of gU,gV at the cs-edge)
232      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
233    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
234      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
235      a maximum grid-scale Reynolds number.  Also, changes all length calculations
236      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
237      Suggested values of viscosity parameters found in mom_calc_visc.
238      Many new viscosity diagnostics available.
239    
240    checkpoint57s_post
241    o Add clearing-house for viscosity calculations, mom_calc_visc and
242      correct numerous bugs in LeithD and Smagorinsky discretizations.  
243      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
244      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
245      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
246      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
247      The Strain-Tension form is now called with useStrainTensonVisc=.true.
248      ViscAhStrain and viscAhTension are now retired.
249    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
250    o In response to JMC's bug report, genmake2 now ignores any soft-links
251      that it finds in the *current* directory when searching for files.
252      Soft-links found in any other source directories will still work as
253      they did before.
254    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
255      a C routine to unlimit the stack size
256    o mnc-ify pkg/aim snapshot vars
257    o mnc-ify pkg/land as requested by Daniel
258    o various changes to mnc including:
259      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
260      - output can now be grouped so that all files within a group
261          change the ITER portion of their names in lock-step together
262      - can now read ("global") PER-FACE (in addition to PER-TILE) files
263          and works with both EXCH1 and EXCH2 (but needs more testing)
264      - writing works for all verification test cases w/ g77 on Linux
265    
266    checkpoint57r_post
267    o make MNC variable initialization happen earlier
268    o add diagnostics for (almost) each term of the momentum Eq.
269    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
270    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
271    o remove MINIMAL_TAVE_OUTPUT option ;
272      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
273    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
274      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
275    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
276    o add time-dependent SST, SSS control
277    o cost terms in ecco/ modularized (new cost_generic.F)
278    o cost_averages routines are modularized (new cost_averagesgeneric.F)
279    o new infrastructure for seaice model vs. obs misfits in seaice/
280      * driver from the_main_loop.F is seaice_cost_driver.F
281      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
282      * gradient check in Exp. 6a of natl_box_adjoint/
283    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
284      (see README file)
285    
286    checkpoint57q_post
287    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
288    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
289      - bug was reported by Jean-Michel and Ian Fenty
290    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
291      update exp. cpl_aim+ocn output.
292    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
293      Needed for high-res. runs with large global files
294      to be able to limit tapelev size
295    o Changed some tests for adjoint:
296      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
297      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
298      * global_ocean.90x40x15/ back to default 3-level checkpointing
299    o Modifications to enable scripted COMMON to MODULE conversion
300      * verification/OpenAD/code/ has necessary scripts and description;
301      * converts, compiles and runs successfully;
302    
303    checkpoint57p_post
304    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
305    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
306      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
307    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
308    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
309      (was already the case for dissipation with mom_vecinv,
310       and also the case for grad.PhiHyd when staggered-timeStep)
311      This will allow to put dissipation out-off the AB time-stepping.
312     Unfortunately, affects truncation error. Update output of exp. that "fails"
313      (cg2d matching number) and leave the others for later: front_relax(10),
314      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
315      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
316    
317    checkpoint57o_post
318    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
319      (2) its ready to be documented during the 20050801 DocFest
320    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
321      for ideal_2D_oce and lab_sea on linux_ia32_g77
322    o set to #undef CTRL_SET_OLD_MAXCVARS_30
323      in global1x1_tot/code_seaice_adj to access indices 32, 33
324      (worth another tag)
325    
326    checkpoint57n_post
327    o adding precip control xx_precip 32
328    o adding swflux control xx_swflux 33
329    o Replacing 10 forcing penalty cost routines by 1 generic.
330    o Implementing partitioning in time-mean and variable adjustment
331      for atmos. state.
332    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
333    o in natl_box_adjoint:
334      * updated exp 1 to 10
335        (but does not have time-mean vs. variable split results yet)
336    o updated global1x1/*_seaice_adj/
337      to incorporate latest changes
338    o enable useSingleCpuIO for mdsio vector routines
339      (applies in particular to tapelev I/O)
340    o removed inefficient K-loop in all active_file*control*.F
341    
342    checkpoint57m_post
343    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
344      and advect_cs (use EXCH-2 and standard cs-32 grid files).
345    o pkg/exch2: filling of face-corner halo regions is optional
346      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
347    
348    checkpoint57l_post
349     tag before updating tutorials (pre-release-2)
350    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
351       for output and interpolation of input fields onto model grid)
352    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
353       Affects results of exp. rotating_tank ; update output.txt.
354    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
355          and taking the square quantity and/or using a fraction-weight field.
356    o fix aim_diagnostics_init.F mate numbers.
357    o add mnc output capability to diagnostics/diagstat and update
358      our cvsignore files for the ACSII output generated

360    checkpoint57k_post
361    o lab_sea now uses diagnostics package and provides a suite of
362      new EXF diagnostics output.
363    
364    checkpoint57j_post
365    o exf
366      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
367        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
368        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
369      * extended diagnostics output
370        - now includes all EXF variables
371        - hs, hl moved to common block
372        - separate S/R for diagnostics, called after ctrl vector is added
373        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
374        - EXFqnet contains true Qnet (i.e. includes qsw)
375      * updated verif. lab_sea, global_with_exf
376      * Rearranging hflux (exf_mapfields -> exf_getforcing)
377        to ensure that diagnostics sees a true EXFqnet
378    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
379    o diagnostics pkg: change pointers so that 1 diagnostic can be used
380      several times with different frequencies.
381    o mnc-ify the thsice package as requested by Daniel Enderton
382      - the monitor--MNC output needs work
383      - many attributes need to be added (most are currently blank)
384    o mnc-ify theaim_v23 package as requested by Daniel Enderton
385      - many attributes need to be added (most are currently blank)
386    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
387    o add Sadourny like discretization to the 4th.O vorticity advection scheme
388    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
389      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
390         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
391    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
392     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
393    
394    checkpoint57i_post
395    o Diagnostics package was changed: diagnostic allocation is now deactivated
396      by setting an empty file name in the namelist (used to be by setting 0 frequency)
397    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
398      add 1rst Order upwind vertical Shear.
399    o add a quick fix for A/B checkpointing in OFFLINE mode
400    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
401      end-run around the C/Fortran linking horror in eesup/src/timers.F
402    o added pkg/runclock: allows user to terminate run based on wall clock
403    o added non-hydrostatic scaling parameter: nh_am2
404    o pkg/my82: futile attempt to make results compiler-independent by adding
405      some "_d 0", etc. no effect.
406    o for mnc output, fill the 'T' coordinate var with myTime and create a
407      separate 'iter' variable for iteration count
408    o pkg/diagnostics:
409      add new capability: output of Global/Regional & per-level statistics ;
410      tested against monitor output (including land & thSIce) on various exp.
411    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
412    
413    checkpoint57h_done
414      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
415      data.diagnostics, data.gchem, data.ptracers) is done.
416    
417    o pkg/diagnostics: prepare for Global/Regional statistics.
418      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
419    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
420      and rename it: DIFFERENT_MULTIPLE
421    
422    checkpoint57h_post
423    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
424    o pkg/diagnostics: change output frequency, now in seconds (instead
425      of Nb of iterations). This requires to change data.diagnostics.
426    checkpoint57h_pre
427    
428    o in mnc, let the user create the output dir if both mnc_outdir_date
429      and mnc_outdir_num are false
430    o add fflags() to pkg/diagnostics which allows one to specify, on a
431      per-file basis, the file precision [default behavior is unchanged]
432    o added diagnostics to pkg/kpp, including computation of mixed layer
433      depth based on a temperature/density criterion
434    o updated verification/natl_box to test the new pkg/kpp diagnostics
435    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
436    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
437    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
438      not mnc -- this mistake was found by JMC and is now corrected
439    
440    checkpoint57g_post
441    o add Adams-Bashforth 3rd Order time stepping:
442      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
443      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
444    checkpoint57g_pre
445    
446    o make lambda[Theta,Salt]ClimRelax spatially varying
447      (default remains spatially uniform constant based on tau)
448    o added new control variables
449      * init. uVel, vVel, etanN
450      * lambda[Theta,Salt]ClimRelax
451    o separate masks used for ctrl_pack/unpack 'from write_grid' output
452      (suggested by G. Forget)
453    
454    checkpoint57f_post
455    o add parameter "baseTime" = model base time = time at iteration zero
456      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
457      account for baseTime shift
458    o move Coriolis arrays from PARAMS.h to GRID.h
459    checkpoint57f_pre
460    
461    o mnc-ifying the seaice package
462    o introduced an alternative length scale calculation for use in the limiting
463      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
464    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
465    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
466      as well as grad(vort3).  Made it compatible with both approximate form
467      for the cubed sphere and full form of these gradients.  Added flag
468      useFullLeith to select between approximate and full form.  
469    o add "d0" in getcon.F to reduce differences between compilers/platforms
470      update output.txt of exp. fizhi-gridalt-hs
471    o change port_rand funtion to allow to set the seed.
472    o fix obscure MNC bug involving conversion between reals and integers
473      - it caused no problems with certain (eg. gcc, ifc) compilers but the
474        new version is now more standards-compliant
475    o adjoint-related modifications
476      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
477      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
478      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
479    
480    checkpoint57e_post
481    o Adding eddy stress controls a la Ferreira et al.
482    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
483    
484    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
485      update output.txt of exp. fizhi-gridalt-hs
486    o add more "Z" dimensions and associated coordinate vars to MNC
487    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
488    o parameter calendarDumps: when set, approximate months (30-31 days) and years
489      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
490      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
491      months and years.  Requires pkg/cal.
492    o diagnostics: add pickup functionality
493      - off by default for backwards compatibility
494      - current version only uses MDSIO -- MNC will be added
495    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
496    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
497    
498    checkpoint57d_post
499    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
500    o modify verification/ideal_2D_oce so that it tests the creation of mnc
501      output from the diagnostics package
502    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
503    o make genmake2 more portable by using ".$FS" instead of ".f" for more
504      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
505    o add coordinate variables to the MNC output from the diagnostics package
506    o change MNC-flags default value: true when useMNC=TRUE
507    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
508      the ability (off by default) to read the grid information using MNC
509    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
510    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
511    o do snap-shot diagnostics at the middle of the time-interval (instead of
512      at the end).
513    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
514      new test for AIM with thSIce + slab-ocean
515    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
516    o move state variable diagnostics to the beginning of the time step ;
517      (note: still needs some work specially for snap-shot diagnostics)
518      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
519    
520    checkpoint57c_post
521    o Change testing option (-ieee) to get closer agreement between g77 & ifort
522    o generate new output.txt files on faulks with g77 & the new -ieee option
523    checkpoint57c_pre
524    
525    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
526      update output.txt of exp. global_ocean.90x40x15
527    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
528      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
529    o add saltFlux(+File) forcing capability with periodicExternalForcing
530    o allow to use pkg diagnostics for GM-Redi & ThSIce output
531    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
532    o improvements for the MNC output from DIAGNOSTICS:
533      - correct handling of the unlimitied dimension
534      - all dims now have associated coordinate variables
535      - variables located at U, V, and Corner ("Z") points are now written
536        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
537        *all* data points are output
538    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
539    o added pkg/seaice/seaice_monitor.F
540    o mdsio_readfield.F can now read files visible only to master MPI process.
541    o pkg/seaice: some test code for ice-modified ocean stress
542    o exf_getffields interpolation defaults to bilinear for all scalar forcing
543      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
544      spurious negative numbers for precipitation and humidity.  Will cause
545      some small numerical differences for integrations using pkg/exf/exf_interp.F.
546    o pkg/ctrl/
547      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
548        May be enabled via doPackDiag
549      *  introduce z-scaling of
550         + gradient (doZscalePack) and
551         + control (doZscaleUnpack)
552    o pkg/mdsio/
553      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
554      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
555    
556    checkpoint57b_post
557    o simplify options in diagnostics_fill arguments (remove weird combinations)
558    o fix MNC coordinate variables so that they now contain per-face index
559      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
560      general, EXCH2 grids are only aligned to a "local" coordinate system
561    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
562    o Implement instantaneous output within pkg diagnostics:
563      setting a negative frequency in data.diagnostics produces
564     "snap-shot" output (as opposed to time-average if freq > 0)
565    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
566      NOTE: change ptracer diagnostics name: use 2 characters to work with
567            more than 9 tracers. Add also diagnostics of advect & diffus flux.
568    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
569      becomes the coordinate variable for the 'T' dimension
570    o add CF-style coordinate variables to MNC
571      - just a first cut:  numbers are meaningless on the cubesphere and
572        missing along the T axis but otherwise it works!
573    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
574    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
575    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
576      this is based directly on what the model compute, so that the content of
577      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
578    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
579    o clean up build options files for SunOS, in particular
580      - remove -traditional from xmakedepend
581      - change -xarch=v9 to -xarch=native for f77
582      - restore use of make (not gmake)
583      - add CC=gcc if using g77
584    o changes per discussion of AM, JMC, & EH3 today:
585      - move redundant "grid" variables out of "state" -- in preparation of
586        creating proper CF-style coordinate variables and in recognition
587        that any/all grid variables can be easily copied (eg. w/NCO) from
588        the grid files into any of the other NetCDF files
589      - *always* output grid variables with MDSIO (this will eventually be
590        changed)
591      - output MNC grid file if useMNC is true
592    o every instance of _END_MASTER() has been found and replaced with
593      _END_MASTER( myThid ) in order to satisfy certain picky Sun
594      preprocessors
595    o re-arrange diagnostics pkg initialisation:
596     - allow each package to extend the available diagnostics list
597     - add some checking and fix small problems (multi-threaded, ...)
598     - new S/R diagnostics_fill (replace fill_diagnostics):
599       look through the short list of active diag. (instead of the long list)
600       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
601    
602    checkpoint57a_post
603    o this set of changes restores TAMC compatibility
604      tested for global_ocean.90x40x15 adjoint on trough
605      (what a pain)
606    
607    checkpoint57a_pre
608    o some modifs in tools/build_options for sunos
609    o call ctrl_pack for ctrl at end for optimcycle=0
610    
611    checkpoint57
612    o add horizontal bi-harmonic viscosity for vertical velocity
613      - new parameter viscA4W (defaults to viscA4)
614      - affects only non-hydrostatic code
615      - to be done: no-slip lateral boundary conditions
616    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
617    o implement Implicit Vertical advection for pTracers
618    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
619      (implemented also for implicit vertical diffusion & advection)
620    o OBCS: extend application of tracer open boundary conditions
621      to a strip beyond the boundary of width Olx/Oly
622    o add call monitor to TAF set of required calls (flow directives)
623      and include in natl_box_adjoint
624    o untangle a few ifdefs related to cost, ctrl, autodiff
625      untangel a few ALLOW_ECCO_OPTIMIZATION
626    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
627      (theta2, salt2 in ecco_cost_weights)
628    
629    checkpoint56c_post
630    o OBCS as control variables
631      - update ctrl_ad_diff.list, obcs_ad_diff.list
632      - remove balance of obcs controls from default
633      - fix index bug nobcs in ctrl_init
634      - fix dummy fields filen in ctrl_pack
635      - add dummy weights for obcs
636    o lsopt: comment out fort.94 output
637    o optim:
638      - remove unnecessary header files
639      - adjusted namelists
640      - add xerbla.F to Makefile
641    o exf:
642      - multiple modifications of exf_check_range
643      - unit change in exf_init_runoff from [m/year] to [m/s]
644    o mdsio:
645      - i/o-vector change debugLevel from debLevA to debLevB
646    
647    checkpoint56b_post
648    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
649      is called from DO_THE_MODEL_IO
650      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
651      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
652      - clean up PTRACERS_WRITE_TIMEAVE a little
653    o add another verification experiment that tests both the cfc-pkg and
654      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
655      reactive tendencies treated inline with regular timestepping
656    o testreport previously did a lousy job of comparing small numbers, so
657      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
658      implemented in the little c-progam tmp_cmpnum.c which is embedded in
659      testreport.
660    o ptracers_monitor: bug fix for MPI
661    
662    checkpoint56a_post
663    o GCHEM: finish reorganizating the package
664      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
665        (introduces another 3D-array for each passive tracer, but only if
666        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
667        gchemTendency is not needed because the timestep is done separately)
668      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
669      - GCHEM is now---more or less cleanly---separate from PTRACERS
670      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
671        so clear to me how that should be done in a general way.
672    o CFC: improve formatting of output in CFC_ATMOS
673    o PTRACERS:
674      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
675        that ALL experiments with ptracers enable can be checked. This makes
676        GCHEM_MONITOR obsolete.
677      - include a runtime parameter PTRACERS_monitorFreq that defaults to
678        monitorFreq
679      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
680    o add PTRACERS (PTR0[1-5]) to testreport output
681    o exf_check_range:
682      * default changed to .TRUE.
683      * will check values for niter0 if debLevA, every timestep if debLevB
684      * STOP in exf_check_range if 'out of range'
685      * range chosen generous to allow for potential extema
686      TBD: a version with stricter range
687           permitted range would be runtime parameters
688  o GMredi:  o GMredi:
689    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
690    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.

696      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
697        this flag is now only visible within GCHEM-pkg routines.
698      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
699        be replaced by a 3D array that is computed before thermodynamics; for
700        this, the tracer ID iTracer had to be included into the parameter list
701        of ptracers_forcing
702      - set up forward_step to call gchem_forcing, that will replace
703        gchem_forcing_int in ptracers_forcing
704      - cleaning up
