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:  o GMredi:
699    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - 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.    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.

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
