5      ==============================      ==============================
6    
7    o move balancing of fluxes before the call of external_forcing_surf
8    o seaice:
9      - correct units of turning angles (now they are really in degrees)
10      - move computation of GWATX/Y out of main routine into dynsolver
11      - initialize GWATX/Y in seaice_init
12    o Apply mask on Fresh-Water flux (needed for SSH forcing).
13      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
14    o seaice: add runtime flags for turning angles (default to zero)
15    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
16      and trend from exf forcing and ctrl control adjustments
17    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
18      (since checkpoint57x_post)
19    o change the default rotation period to 86164.s = the Earth rotation
20    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
21      and based on a reference stratification. Tested within hs94.cs-32x32x5.
22    o seaice advection: add code for choosing between the default (2nd order
23      central differences) and multiDim advection schemes provided by
24      pkg/generic_advdiff
25    o seaice:
26      - removed all references to SEAICE_GRID.h fields from
27        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
28        (cubed-sphere configuration will change a little)
29      - grid computations in seaice_init are obsolete now.
30      - cleaned up code a little so that is easier to read (hopefully).
31      - added new (better?) discretizations of default advection and diffusion
32        (turn on with SEAICEuseFluxForm)
33      - replace 1 in 3d global fields by kSurface in growth.F
34      
35    checkpoint58a_post
36    o seaice:
37      - bug fix in advect.F
38    o shelfice:
39      - separate shelfice load anomaly from pload (breaks with time
40        dependent forcing), => introduce constant field shelficeLoadAnomaly.
41        Its default is 0., but it may be computed more cleverly from (unknown)
42        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
43        done offline. A good approximation of the pressure load anomaly is
44        necessary to avoid large initial adjustment processes underneath
45        deep-reaching shelfice.
46      - small fix in ISOMIP shelfice_thermodynamics
47      - add more sophisticated thermodynamics of Hellmer (1989), this is
48        now the default
49      - give a few constants more intuitive names
50    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
51      if bulk formulae are used in long integration (especially EmPmR). Turn
52      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
53      if balancePrintMean, the imbalance that is substracted is printed to
54      STDOUT.
55    o fix bug (typo) in obcs_apply_eta.F
56    o add a new package shelfice which enables us to model the circulation
57      underneath shelf-ice with draughts of hundreds of meters.
58     - works
59     - to do: + include improved thermodynamics
60              + check whether kSurfC (from model/inc/SURFACE.h) can be used
61                instead of new field kTopC
62              + can we use topoFile, Ro_surf and existing code in ini_depth.F
63                instead of new field R_shelfIce and new code in ini_depth.F
64                and ini_mask_etc.F?
65              + adjust vertical mixing schemes?
66    o seaice pkg:
67     - add a cpp-flag to include a simple formula for a salinity dependent
68       freezing point of sea water at the surface
69     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
70       meridional stresses are now different (and hopefully correct)
71    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
72       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
73       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
74    o pkg/diagnostics: add options and parameters for regional-statistics
75       diagnostics ; define regions by reading a region-mask from a file
76       (might add other options later)
77    o pkg/bulk_force:
78     - add option and parameters to use AIM surface-flux formulae.
79     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
80       others forcing fields (defined in PARM05, parameter file "data") are loaded
81       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
82     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
83     - use the right EXCH call for uwind,vwind (to work on CS-grid).
84     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
85       and parameters (note: calcWindStress replaces .NOT.readwindstress).
86     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
87    
88    checkpoint58
89    o add "--embed-source" option to genmake2 which, when the supporting
90      tools can be compiled (as determined by genmake2) will turn on the
91      embed_files package which then embeds the entire MITgcm source code
92      (*.[fFhc] + Makefile) used for the build within the executable
93      - requested by CNH but off by default
94      - adds a paltry <9MB to the mitgcmuv executable in most cases
95      - only writes the output when useEMBEDSRC in eedata is true
96    o clean up 3-dim. relaxation codes:
97      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
98      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
99      * Thanks to Tom Haine for testing!
100    
101    checkpoint57z_post
102    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
103      affects output (@ truncation level) of exp. plume_on_slope ; updated.
104    o fix the pickup behavior for obcs in combination with ptracers
105    o fix a bug in ptracers_external_fields_load
106    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
107      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
108    o transfered surface NH pressure to eta field (if exactConserv).
109    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
110         and update lab_sea output.txt file.
111    o completing 3-dim. relaxation code: additional term
112         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
113      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
114      * At compile time, in "EXF_OPTIONS.h" set
115          #define  ALLOW_CLIMTEMP_RELAXATION
116          #define  ALLOW_CLIMSALT_RELAXATION
117      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
118          tauThetaClimRelax3Dim = 15552000.0,
119          tauSaltClimRelax3Dim  = 15552000.0,
120      * 3 cases:
121          1) Use a constant-in-time 3-dim. field
122          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
123          3) Real-time relax. to time-evolving prescribed field
124    o Adding Laplacian-type smoothness constraint on
125      initial and boundary (forcing) controls (ic, bc)
126      * enable at compile-time via
127        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
128      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
129      * Absolute scale somewhat unclear so far
130      * no area weighting was included since no other cost term does so far
131    
132    checkpoint57y_post
133    First step for a NLFS adjoint
134    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
135    o new init. routines for calc_r_star, calc_surf_dr
136    o still need to deal with ini_masks_etc
137    o testreport seemed happy
138    checkpoint57y_pre
139    
140    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
141    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
142    o add new offset feature to offline pkg (plus minor cleanup)
143    o cfc fixes for final year of integration
144    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
145      be in GCHEM_OPTIONS).
146    
147    checkpoint57x_post
148    o fix testreport Pb in multiple test experiment.
149    o cleanup our namelist syntax in verification:
150      - make it more F95 standards compliant (some work still needed)
151      - allows the vast majority of our tests to work with gfortran
152    o Non-Hydrostatic:
153     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
154     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
155    o Allow to apply AB on T,S rather than on AB(gT,gS):
156     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
157     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
158       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
159     - need a "clever" read_pickup to restart from the other AB formulation
160    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
161    o remove some unused variables (reduces number of compiler warnings)
162    o adjoint
163      * Disable useVariableViscosity for adjoint for time being
164        (there are a number of extensive recomputations)
165      * Initialize certain variables needed for adjoint
166    
167    checkpoint57w_post
168    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
169                 fix the singleCpuIO RS version of MDSWRITEFIELD
170       and add a WARNING if using globalFiles=T with multi-processors.
171    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
172      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
173    o tracer advection scheme:
174      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
175       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
176       was not very convenient).
177      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
178       (further tests needed for the implicit DST & Flux-Limiter schemes).
179    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
180      and sRef for convenience, handy, when you want to initialize
181      ptracers in a large domain with a constant non-zero value. Also,
182      untangle ptracers_init.F a little.
183    
184    checkpoint57v_post
185    o change dome exp. to use variable viscosity in side-drag terms.
186    o remove all the files from the cfc_offline test since they are now
187      incorporated into tutorial_cfc_offline which has been producing
188      identical results for a few days of testing
189    o add new parameter: sideDragFactor to enable half-slip-side BC
190      and change side-drag S/R to use viscosity from mom_calc_visc
191      (can switch back by setting sideDragFactor=0.); affects results at
192      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
193       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
194    o vorticity & strain are now computed without masking, to account for
195      no-slip-side BC in variable viscosity calculation ; mask is applied
196      anyway later on, before computing advection/coriolis terms.
197    o modify exp4 to test new obcs support for reading from external files
198      and for passive tracers
199    o fix behavior of ptracers_monitor when monitor output is written to a
200      netcdf-file; still not independent of monitor.F (writes in the same
201      file).
202    o change default value of tRef (put a uniform, meaningful value for ocean
203      & atmos) and initialize sRef (was missing, as Martin mentioned).
204    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
205      to be proportional to enstrophy dissipation length.  Thus,
206       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
207      This is now consistent with Smagorinsky and with the manual.
208    
209    checkpoint57u_post
210    o OBCS and PTRACERS: add open boundary support for passive tracers
211      - either use homogenous (pseudo) v.Neumann conditions or prescribe
212        OB-values from file; this is not different from the way theta and salinity
213        are treated
214      - however, Orlanski-radiation conditions are not supported, and the model
215        will stop if you use pTracers and Orlanski at the same time.
216      - beefed up the rountine obcs_external_fields_load: now only those open
217        boundary values are overwritten with values from files for which there
218        are really files, otherwise the OB-fields remain untouched. This makes
219        it possible to use different OBs at different ends of the domain (as
220        with EXF)
221    o reduce number of exch calls in shap_filt (s2).
222    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
223      truncation level) 4/5 MLAdjust test results (11&12 digits match).
224    
225    checkpoint57t_post
226    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
227    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
228      same truncation, independent of the face number: affects affects several
229      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
230    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
231      note that biharmonic viscosity + no-slip was not tested in any experiment.
232    o fix bug in non-linear free-surf side-drag ; generate new output for
233      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
234    o make mnc honor the writeBinaryPrec flag for most kinds of output
235    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
236    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
237      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
238    o add brackets in multi-terms sum to get same truncation, independent of
239      the face number (manage to get exactly same value of gU,gV at the cs-edge)
240      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
241    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
242      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
243      a maximum grid-scale Reynolds number.  Also, changes all length calculations
244      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
245      Suggested values of viscosity parameters found in mom_calc_visc.
246      Many new viscosity diagnostics available.
247    
248    checkpoint57s_post
249    o Add clearing-house for viscosity calculations, mom_calc_visc and
250      correct numerous bugs in LeithD and Smagorinsky discretizations.  
251      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
252      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
253      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
254      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
255      The Strain-Tension form is now called with useStrainTensonVisc=.true.
256      ViscAhStrain and viscAhTension are now retired.
257    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
258    o In response to JMC's bug report, genmake2 now ignores any soft-links
259      that it finds in the *current* directory when searching for files.
260      Soft-links found in any other source directories will still work as
261      they did before.
262    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
263      a C routine to unlimit the stack size
264    o mnc-ify pkg/aim snapshot vars
265    o mnc-ify pkg/land as requested by Daniel
266    o various changes to mnc including:
267      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
268      - output can now be grouped so that all files within a group
269          change the ITER portion of their names in lock-step together
270      - can now read ("global") PER-FACE (in addition to PER-TILE) files
271          and works with both EXCH1 and EXCH2 (but needs more testing)
272      - writing works for all verification test cases w/ g77 on Linux
273    
274    checkpoint57r_post
275    o make MNC variable initialization happen earlier
276    o add diagnostics for (almost) each term of the momentum Eq.
277    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
278    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
279    o remove MINIMAL_TAVE_OUTPUT option ;
280      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
281    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
282      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
283    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
284    o add time-dependent SST, SSS control
285    o cost terms in ecco/ modularized (new cost_generic.F)
286    o cost_averages routines are modularized (new cost_averagesgeneric.F)
287    o new infrastructure for seaice model vs. obs misfits in seaice/
288      * driver from the_main_loop.F is seaice_cost_driver.F
289      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
290      * gradient check in Exp. 6a of natl_box_adjoint/
291    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
292      (see README file)
293    
294    checkpoint57q_post
295    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
296    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
297      - bug was reported by Jean-Michel and Ian Fenty
298    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
299      update exp. cpl_aim+ocn output.
300    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
301      Needed for high-res. runs with large global files
302      to be able to limit tapelev size
303    o Changed some tests for adjoint:
304      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
305      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
306      * global_ocean.90x40x15/ back to default 3-level checkpointing
307    o Modifications to enable scripted COMMON to MODULE conversion
308      * verification/OpenAD/code/ has necessary scripts and description;
309      * converts, compiles and runs successfully;
310    
311    checkpoint57p_post
312    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
313    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
314      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
315    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
316    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
317      (was already the case for dissipation with mom_vecinv,
318       and also the case for grad.PhiHyd when staggered-timeStep)
319      This will allow to put dissipation out-off the AB time-stepping.
320     Unfortunately, affects truncation error. Update output of exp. that "fails"
321      (cg2d matching number) and leave the others for later: front_relax(10),
322      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
323      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
324    
325    checkpoint57o_post
326    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
327      (2) its ready to be documented during the 20050801 DocFest
328    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
329      for ideal_2D_oce and lab_sea on linux_ia32_g77
330    o set to #undef CTRL_SET_OLD_MAXCVARS_30
331      in global1x1_tot/code_seaice_adj to access indices 32, 33
332      (worth another tag)
333    
334    checkpoint57n_post
335    o adding precip control xx_precip 32
336    o adding swflux control xx_swflux 33
337    o Replacing 10 forcing penalty cost routines by 1 generic.
338    o Implementing partitioning in time-mean and variable adjustment
339      for atmos. state.
340    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
341    o in natl_box_adjoint:
342      * updated exp 1 to 10
343        (but does not have time-mean vs. variable split results yet)
344    o updated global1x1/*_seaice_adj/
345      to incorporate latest changes
346    o enable useSingleCpuIO for mdsio vector routines
347      (applies in particular to tapelev I/O)
348    o removed inefficient K-loop in all active_file*control*.F
349    
350    checkpoint57m_post
351    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
352      and advect_cs (use EXCH-2 and standard cs-32 grid files).
353    o pkg/exch2: filling of face-corner halo regions is optional
354      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
355    
356    checkpoint57l_post
357     tag before updating tutorials (pre-release-2)
358    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
359       for output and interpolation of input fields onto model grid)
360    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
361       Affects results of exp. rotating_tank ; update output.txt.
362    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
363          and taking the square quantity and/or using a fraction-weight field.
364    o fix aim_diagnostics_init.F mate numbers.
365    o add mnc output capability to diagnostics/diagstat and update
366      our cvsignore files for the ACSII output generated
367    
368    checkpoint57k_post
369    o lab_sea now uses diagnostics package and provides a suite of
370      new EXF diagnostics output.
371    
372    checkpoint57j_post
373    o exf
374      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
375        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
376        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
377      * extended diagnostics output
378        - now includes all EXF variables
379        - hs, hl moved to common block
380        - separate S/R for diagnostics, called after ctrl vector is added
381        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
382        - EXFqnet contains true Qnet (i.e. includes qsw)
383      * updated verif. lab_sea, global_with_exf
384      * Rearranging hflux (exf_mapfields -> exf_getforcing)
385        to ensure that diagnostics sees a true EXFqnet
386    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
387    o diagnostics pkg: change pointers so that 1 diagnostic can be used
388      several times with different frequencies.
389    o mnc-ify the thsice package as requested by Daniel Enderton
390      - the monitor--MNC output needs work
391      - many attributes need to be added (most are currently blank)
392    o mnc-ify theaim_v23 package as requested by Daniel Enderton
393      - many attributes need to be added (most are currently blank)
394    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
395    o add Sadourny like discretization to the 4th.O vorticity advection scheme
396    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
397      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
398         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
399    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
400     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
401    
402    checkpoint57i_post
403    o Diagnostics package was changed: diagnostic allocation is now deactivated
404      by setting an empty file name in the namelist (used to be by setting 0 frequency)
405    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
406      add 1rst Order upwind vertical Shear.
407    o add a quick fix for A/B checkpointing in OFFLINE mode
408    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
409      end-run around the C/Fortran linking horror in eesup/src/timers.F
410    o added pkg/runclock: allows user to terminate run based on wall clock
411    o added non-hydrostatic scaling parameter: nh_am2
412    o pkg/my82: futile attempt to make results compiler-independent by adding
413      some "_d 0", etc. no effect.
414    o for mnc output, fill the 'T' coordinate var with myTime and create a
415      separate 'iter' variable for iteration count
416    o pkg/diagnostics:
417      add new capability: output of Global/Regional & per-level statistics ;
418      tested against monitor output (including land & thSIce) on various exp.
419    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
420    
421    checkpoint57h_done
422      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
423      data.diagnostics, data.gchem, data.ptracers) is done.
424    
425    o pkg/diagnostics: prepare for Global/Regional statistics.
426      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
427    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
428      and rename it: DIFFERENT_MULTIPLE
429    
430    checkpoint57h_post
431    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
432    o pkg/diagnostics: change output frequency, now in seconds (instead
433      of Nb of iterations). This requires to change data.diagnostics.
434    checkpoint57h_pre
435    
436    o in mnc, let the user create the output dir if both mnc_outdir_date
437      and mnc_outdir_num are false
438    o add fflags() to pkg/diagnostics which allows one to specify, on a
439      per-file basis, the file precision [default behavior is unchanged]
440    o added diagnostics to pkg/kpp, including computation of mixed layer
441      depth based on a temperature/density criterion
442    o updated verification/natl_box to test the new pkg/kpp diagnostics
443    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
444    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
445    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
446      not mnc -- this mistake was found by JMC and is now corrected
447    
448    checkpoint57g_post
449    o add Adams-Bashforth 3rd Order time stepping:
450      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
451      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
452    checkpoint57g_pre
453    
454    o make lambda[Theta,Salt]ClimRelax spatially varying
455      (default remains spatially uniform constant based on tau)
456    o added new control variables
457      * init. uVel, vVel, etanN
458      * lambda[Theta,Salt]ClimRelax
459    o separate masks used for ctrl_pack/unpack 'from write_grid' output
460      (suggested by G. Forget)
461    
462    checkpoint57f_post
463    o add parameter "baseTime" = model base time = time at iteration zero
464      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
465      account for baseTime shift
466    o move Coriolis arrays from PARAMS.h to GRID.h
467    checkpoint57f_pre
468    
469    o mnc-ifying the seaice package
470    o introduced an alternative length scale calculation for use in the limiting
471      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
472    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
473    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
474      as well as grad(vort3).  Made it compatible with both approximate form
475      for the cubed sphere and full form of these gradients.  Added flag
476      useFullLeith to select between approximate and full form.  
477    o add "d0" in getcon.F to reduce differences between compilers/platforms
478      update output.txt of exp. fizhi-gridalt-hs
479    o change port_rand funtion to allow to set the seed.
480    o fix obscure MNC bug involving conversion between reals and integers
481      - it caused no problems with certain (eg. gcc, ifc) compilers but the
482        new version is now more standards-compliant
483    o adjoint-related modifications
484      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
485      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
486      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
487    
488    checkpoint57e_post
489    o Adding eddy stress controls a la Ferreira et al.
490    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
491    
492    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
493      update output.txt of exp. fizhi-gridalt-hs
494    o add more "Z" dimensions and associated coordinate vars to MNC
495    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
496    o parameter calendarDumps: when set, approximate months (30-31 days) and years
497      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
498      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
499      months and years.  Requires pkg/cal.
500    o diagnostics: add pickup functionality
501      - off by default for backwards compatibility
502      - current version only uses MDSIO -- MNC will be added
503    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
504    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
505    
506    checkpoint57d_post
507    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
508    o modify verification/ideal_2D_oce so that it tests the creation of mnc
509      output from the diagnostics package
510    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
511    o make genmake2 more portable by using ".$FS" instead of ".f" for more
512      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
513    o add coordinate variables to the MNC output from the diagnostics package
514    o change MNC-flags default value: true when useMNC=TRUE
515    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
516      the ability (off by default) to read the grid information using MNC
517    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
518    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
519    o do snap-shot diagnostics at the middle of the time-interval (instead of
520      at the end).
521    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
522      new test for AIM with thSIce + slab-ocean
523    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
524    o move state variable diagnostics to the beginning of the time step ;
525      (note: still needs some work specially for snap-shot diagnostics)
526      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
527    
528    checkpoint57c_post
529    o Change testing option (-ieee) to get closer agreement between g77 & ifort
530    o generate new output.txt files on faulks with g77 & the new -ieee option
531    checkpoint57c_pre
532    
533    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
534      update output.txt of exp. global_ocean.90x40x15
535    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
536      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
537    o add saltFlux(+File) forcing capability with periodicExternalForcing
538    o allow to use pkg diagnostics for GM-Redi & ThSIce output
539    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
540    o improvements for the MNC output from DIAGNOSTICS:
541      - correct handling of the unlimitied dimension
542      - all dims now have associated coordinate variables
543      - variables located at U, V, and Corner ("Z") points are now written
544        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
545        *all* data points are output
546    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
547    o added pkg/seaice/seaice_monitor.F
548    o mdsio_readfield.F can now read files visible only to master MPI process.
549    o pkg/seaice: some test code for ice-modified ocean stress
550    o exf_getffields interpolation defaults to bilinear for all scalar forcing
551      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
552      spurious negative numbers for precipitation and humidity.  Will cause
553      some small numerical differences for integrations using pkg/exf/exf_interp.F.
554    o pkg/ctrl/
555      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
556        May be enabled via doPackDiag
557      *  introduce z-scaling of
558         + gradient (doZscalePack) and
559         + control (doZscaleUnpack)
560    o pkg/mdsio/
561      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
562      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
563    
564    checkpoint57b_post
565    o simplify options in diagnostics_fill arguments (remove weird combinations)
566    o fix MNC coordinate variables so that they now contain per-face index
567      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
568      general, EXCH2 grids are only aligned to a "local" coordinate system
569    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
570    o Implement instantaneous output within pkg diagnostics:
571      setting a negative frequency in data.diagnostics produces
572     "snap-shot" output (as opposed to time-average if freq > 0)
573    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
574      NOTE: change ptracer diagnostics name: use 2 characters to work with
575            more than 9 tracers. Add also diagnostics of advect & diffus flux.
576    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
577      becomes the coordinate variable for the 'T' dimension
578    o add CF-style coordinate variables to MNC
579      - just a first cut:  numbers are meaningless on the cubesphere and
580        missing along the T axis but otherwise it works!
581    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
582    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
583    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
584      this is based directly on what the model compute, so that the content of
585      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
586    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
587    o clean up build options files for SunOS, in particular
588      - remove -traditional from xmakedepend
589      - change -xarch=v9 to -xarch=native for f77
590      - restore use of make (not gmake)
591      - add CC=gcc if using g77
592    o changes per discussion of AM, JMC, & EH3 today:
593      - move redundant "grid" variables out of "state" -- in preparation of
594        creating proper CF-style coordinate variables and in recognition
595        that any/all grid variables can be easily copied (eg. w/NCO) from
596        the grid files into any of the other NetCDF files
597      - *always* output grid variables with MDSIO (this will eventually be
598        changed)
599      - output MNC grid file if useMNC is true
600    o every instance of _END_MASTER() has been found and replaced with
601      _END_MASTER( myThid ) in order to satisfy certain picky Sun
602      preprocessors
603    o re-arrange diagnostics pkg initialisation:
604     - allow each package to extend the available diagnostics list
605     - add some checking and fix small problems (multi-threaded, ...)
606     - new S/R diagnostics_fill (replace fill_diagnostics):
607       look through the short list of active diag. (instead of the long list)
608       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
609    
610    checkpoint57a_post
611    o this set of changes restores TAMC compatibility
612      tested for global_ocean.90x40x15 adjoint on trough
613      (what a pain)
614    
615    checkpoint57a_pre
616    o some modifs in tools/build_options for sunos
617    o call ctrl_pack for ctrl at end for optimcycle=0
618    
619    checkpoint57
620    o add horizontal bi-harmonic viscosity for vertical velocity
621      - new parameter viscA4W (defaults to viscA4)
622      - affects only non-hydrostatic code
623      - to be done: no-slip lateral boundary conditions
624    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
625    o implement Implicit Vertical advection for pTracers
626    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
627      (implemented also for implicit vertical diffusion & advection)
628    o OBCS: extend application of tracer open boundary conditions
629      to a strip beyond the boundary of width Olx/Oly
630    o add call monitor to TAF set of required calls (flow directives)
631      and include in natl_box_adjoint
632    o untangle a few ifdefs related to cost, ctrl, autodiff
633      untangel a few ALLOW_ECCO_OPTIMIZATION
634    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
635      (theta2, salt2 in ecco_cost_weights)
636    
637    checkpoint56c_post
638    o OBCS as control variables
639      - update ctrl_ad_diff.list, obcs_ad_diff.list
640      - remove balance of obcs controls from default
641      - fix index bug nobcs in ctrl_init
642      - fix dummy fields filen in ctrl_pack
643      - add dummy weights for obcs
644    o lsopt: comment out fort.94 output
645    o optim:
646      - remove unnecessary header files
647      - adjusted namelists
648      - add xerbla.F to Makefile
649    o exf:
650      - multiple modifications of exf_check_range
651      - unit change in exf_init_runoff from [m/year] to [m/s]
652    o mdsio:
653      - i/o-vector change debugLevel from debLevA to debLevB
654    
655    checkpoint56b_post
656    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
657      is called from DO_THE_MODEL_IO
658      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
659      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
660      - clean up PTRACERS_WRITE_TIMEAVE a little
661    o add another verification experiment that tests both the cfc-pkg and
662      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
663      reactive tendencies treated inline with regular timestepping
664    o testreport previously did a lousy job of comparing small numbers, so
665      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
666      implemented in the little c-progam tmp_cmpnum.c which is embedded in
667      testreport.
668    o ptracers_monitor: bug fix for MPI
669    
670    checkpoint56a_post
671    o GCHEM: finish reorganizating the package
672      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
673        (introduces another 3D-array for each passive tracer, but only if
674        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
675        gchemTendency is not needed because the timestep is done separately)
676      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
677      - GCHEM is now---more or less cleanly---separate from PTRACERS
678      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
679        so clear to me how that should be done in a general way.
680    o CFC: improve formatting of output in CFC_ATMOS
681    o PTRACERS:
682      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
683        that ALL experiments with ptracers enable can be checked. This makes
684        GCHEM_MONITOR obsolete.
685      - include a runtime parameter PTRACERS_monitorFreq that defaults to
686        monitorFreq
687      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
688    o add PTRACERS (PTR0[1-5]) to testreport output
689  o exf_check_range:  o exf_check_range:
690    * default changed to .TRUE.    * default changed to .TRUE.
691    * will check values for niter0 if debLevA, every timestep if debLevB    * will check values for niter0 if debLevA, every timestep if debLevB
