5      ==============================      ==============================
6    
7    o Apply mask on Fresh-Water flux (needed for SSH forcing).
8      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
9    o seaice: add runtime flags for turning angles (default to zero)
10    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
11      and trend from exf forcing and ctrl control adjustments
12    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
13      (since checkpoint57x_post)
14    o change the default rotation period to 86164.s = the Earth rotation
15    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
16      and based on a reference stratification. Tested within hs94.cs-32x32x5.
17    o seaice advection: add code for choosing between the default (2nd order
18      central differences) and multiDim advection schemes provided by
19      pkg/generic_advdiff
20    o seaice:
21      - removed all references to SEAICE_GRID.h fields from
22        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
23        (cubed-sphere configuration will change a little)
24      - grid computations in seaice_init are obsolete now.
25      - cleaned up code a little so that is easier to read (hopefully).
26      - added new (better?) discretizations of default advection and diffusion
27        (turn on with SEAICEuseFluxForm)
28      - replace 1 in 3d global fields by kSurface in growth.F
29      
30    checkpoint58a_post
31    o seaice:
32      - bug fix in advect.F
33    o shelfice:
34      - separate shelfice load anomaly from pload (breaks with time
35        dependent forcing), => introduce constant field shelficeLoadAnomaly.
36        Its default is 0., but it may be computed more cleverly from (unknown)
37        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
38        done offline. A good approximation of the pressure load anomaly is
39        necessary to avoid large initial adjustment processes underneath
40        deep-reaching shelfice.
41      - small fix in ISOMIP shelfice_thermodynamics
42      - add more sophisticated thermodynamics of Hellmer (1989), this is
43        now the default
44      - give a few constants more intuitive names
45    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
46      if bulk formulae are used in long integration (especially EmPmR). Turn
47      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
48      if balancePrintMean, the imbalance that is substracted is printed to
49      STDOUT.
50    o fix bug (typo) in obcs_apply_eta.F
51    o add a new package shelfice which enables us to model the circulation
52      underneath shelf-ice with draughts of hundreds of meters.
53     - works
54     - to do: + include improved thermodynamics
55              + check whether kSurfC (from model/inc/SURFACE.h) can be used
56                instead of new field kTopC
57              + can we use topoFile, Ro_surf and existing code in ini_depth.F
58                instead of new field R_shelfIce and new code in ini_depth.F
59                and ini_mask_etc.F?
60              + adjust vertical mixing schemes?
61    o seaice pkg:
62     - add a cpp-flag to include a simple formula for a salinity dependent
63       freezing point of sea water at the surface
64     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
65       meridional stresses are now different (and hopefully correct)
66    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
67       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
68       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
69    o pkg/diagnostics: add options and parameters for regional-statistics
70       diagnostics ; define regions by reading a region-mask from a file
71       (might add other options later)
72    o pkg/bulk_force:
73     - add option and parameters to use AIM surface-flux formulae.
74     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
75       others forcing fields (defined in PARM05, parameter file "data") are loaded
76       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
77     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
78     - use the right EXCH call for uwind,vwind (to work on CS-grid).
79     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
80       and parameters (note: calcWindStress replaces .NOT.readwindstress).
81     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
82    
83    checkpoint58
84    o add "--embed-source" option to genmake2 which, when the supporting
85      tools can be compiled (as determined by genmake2) will turn on the
86      embed_files package which then embeds the entire MITgcm source code
87      (*.[fFhc] + Makefile) used for the build within the executable
88      - requested by CNH but off by default
89      - adds a paltry <9MB to the mitgcmuv executable in most cases
90      - only writes the output when useEMBEDSRC in eedata is true
91    o clean up 3-dim. relaxation codes:
92      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
93      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
94      * Thanks to Tom Haine for testing!
95    
96    checkpoint57z_post
97    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
98      affects output (@ truncation level) of exp. plume_on_slope ; updated.
99    o fix the pickup behavior for obcs in combination with ptracers
100    o fix a bug in ptracers_external_fields_load
101    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
102      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
103    o transfered surface NH pressure to eta field (if exactConserv).
104    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
105         and update lab_sea output.txt file.
106    o completing 3-dim. relaxation code: additional term
107         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
108      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
109      * At compile time, in "EXF_OPTIONS.h" set
110          #define  ALLOW_CLIMTEMP_RELAXATION
111          #define  ALLOW_CLIMSALT_RELAXATION
112      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
113          tauThetaClimRelax3Dim = 15552000.0,
114          tauSaltClimRelax3Dim  = 15552000.0,
115      * 3 cases:
116          1) Use a constant-in-time 3-dim. field
117          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
118          3) Real-time relax. to time-evolving prescribed field
119    o Adding Laplacian-type smoothness constraint on
120      initial and boundary (forcing) controls (ic, bc)
121      * enable at compile-time via
122        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
123      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
124      * Absolute scale somewhat unclear so far
125      * no area weighting was included since no other cost term does so far
126    
127    checkpoint57y_post
128    First step for a NLFS adjoint
129    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
130    o new init. routines for calc_r_star, calc_surf_dr
131    o still need to deal with ini_masks_etc
132    o testreport seemed happy
133    checkpoint57y_pre
134    
135    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
136    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
137    o add new offset feature to offline pkg (plus minor cleanup)
138    o cfc fixes for final year of integration
139    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
140      be in GCHEM_OPTIONS).
141    
142    checkpoint57x_post
143    o fix testreport Pb in multiple test experiment.
144    o cleanup our namelist syntax in verification:
145      - make it more F95 standards compliant (some work still needed)
146      - allows the vast majority of our tests to work with gfortran
147    o Non-Hydrostatic:
148     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
149     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
150    o Allow to apply AB on T,S rather than on AB(gT,gS):
151     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
152     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
153       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
154     - need a "clever" read_pickup to restart from the other AB formulation
155    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
156    o remove some unused variables (reduces number of compiler warnings)
157    o adjoint
158      * Disable useVariableViscosity for adjoint for time being
159        (there are a number of extensive recomputations)
160      * Initialize certain variables needed for adjoint
161    
162    checkpoint57w_post
163    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
164                 fix the singleCpuIO RS version of MDSWRITEFIELD
165       and add a WARNING if using globalFiles=T with multi-processors.
166    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
167      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
168    o tracer advection scheme:
169      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
170       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
171       was not very convenient).
172      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
173       (further tests needed for the implicit DST & Flux-Limiter schemes).
174    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
175      and sRef for convenience, handy, when you want to initialize
176      ptracers in a large domain with a constant non-zero value. Also,
177      untangle ptracers_init.F a little.
178    
179    checkpoint57v_post
180    o change dome exp. to use variable viscosity in side-drag terms.
181    o remove all the files from the cfc_offline test since they are now
182      incorporated into tutorial_cfc_offline which has been producing
183      identical results for a few days of testing
184    o add new parameter: sideDragFactor to enable half-slip-side BC
185      and change side-drag S/R to use viscosity from mom_calc_visc
186      (can switch back by setting sideDragFactor=0.); affects results at
187      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
188       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
189    o vorticity & strain are now computed without masking, to account for
190      no-slip-side BC in variable viscosity calculation ; mask is applied
191      anyway later on, before computing advection/coriolis terms.
192    o modify exp4 to test new obcs support for reading from external files
193      and for passive tracers
194    o fix behavior of ptracers_monitor when monitor output is written to a
195      netcdf-file; still not independent of monitor.F (writes in the same
196      file).
197    o change default value of tRef (put a uniform, meaningful value for ocean
198      & atmos) and initialize sRef (was missing, as Martin mentioned).
199    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
200      to be proportional to enstrophy dissipation length.  Thus,
201       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
202      This is now consistent with Smagorinsky and with the manual.
203    
204    checkpoint57u_post
205    o OBCS and PTRACERS: add open boundary support for passive tracers
206      - either use homogenous (pseudo) v.Neumann conditions or prescribe
207        OB-values from file; this is not different from the way theta and salinity
208        are treated
209      - however, Orlanski-radiation conditions are not supported, and the model
210        will stop if you use pTracers and Orlanski at the same time.
211      - beefed up the rountine obcs_external_fields_load: now only those open
212        boundary values are overwritten with values from files for which there
213        are really files, otherwise the OB-fields remain untouched. This makes
214        it possible to use different OBs at different ends of the domain (as
215        with EXF)
216    o reduce number of exch calls in shap_filt (s2).
217    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
218      truncation level) 4/5 MLAdjust test results (11&12 digits match).
219    
220    checkpoint57t_post
221    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
222    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
223      same truncation, independent of the face number: affects affects several
224      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
225    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
226      note that biharmonic viscosity + no-slip was not tested in any experiment.
227    o fix bug in non-linear free-surf side-drag ; generate new output for
228      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
229    o make mnc honor the writeBinaryPrec flag for most kinds of output
230    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
231    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
232      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
233    o add brackets in multi-terms sum to get same truncation, independent of
234      the face number (manage to get exactly same value of gU,gV at the cs-edge)
235      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
236    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
237      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
238      a maximum grid-scale Reynolds number.  Also, changes all length calculations
239      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
240      Suggested values of viscosity parameters found in mom_calc_visc.
241      Many new viscosity diagnostics available.
242    
243    checkpoint57s_post
244    o Add clearing-house for viscosity calculations, mom_calc_visc and
245      correct numerous bugs in LeithD and Smagorinsky discretizations.  
246      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
247      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
248      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
249      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
250      The Strain-Tension form is now called with useStrainTensonVisc=.true.
251      ViscAhStrain and viscAhTension are now retired.
252    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
253    o In response to JMC's bug report, genmake2 now ignores any soft-links
254      that it finds in the *current* directory when searching for files.
255      Soft-links found in any other source directories will still work as
256      they did before.
257    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
258      a C routine to unlimit the stack size
259    o mnc-ify pkg/aim snapshot vars
260    o mnc-ify pkg/land as requested by Daniel
261    o various changes to mnc including:
262      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
263      - output can now be grouped so that all files within a group
264          change the ITER portion of their names in lock-step together
265      - can now read ("global") PER-FACE (in addition to PER-TILE) files
266          and works with both EXCH1 and EXCH2 (but needs more testing)
267      - writing works for all verification test cases w/ g77 on Linux
268    
269    checkpoint57r_post
270    o make MNC variable initialization happen earlier
271    o add diagnostics for (almost) each term of the momentum Eq.
272    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
273    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
274    o remove MINIMAL_TAVE_OUTPUT option ;
275      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
276    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
277      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
278    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
279    o add time-dependent SST, SSS control
280    o cost terms in ecco/ modularized (new cost_generic.F)
281    o cost_averages routines are modularized (new cost_averagesgeneric.F)
282    o new infrastructure for seaice model vs. obs misfits in seaice/
283      * driver from the_main_loop.F is seaice_cost_driver.F
284      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
285      * gradient check in Exp. 6a of natl_box_adjoint/
286    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
287      (see README file)
288    
289    checkpoint57q_post
290    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
291    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
292      - bug was reported by Jean-Michel and Ian Fenty
293    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
294      update exp. cpl_aim+ocn output.
295    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
296      Needed for high-res. runs with large global files
297      to be able to limit tapelev size
298    o Changed some tests for adjoint:
299      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
300      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
301      * global_ocean.90x40x15/ back to default 3-level checkpointing
302    o Modifications to enable scripted COMMON to MODULE conversion
303      * verification/OpenAD/code/ has necessary scripts and description;
304      * converts, compiles and runs successfully;
305    
306    checkpoint57p_post
307    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
308    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
309      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
310    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
311    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
312      (was already the case for dissipation with mom_vecinv,
313       and also the case for grad.PhiHyd when staggered-timeStep)
314      This will allow to put dissipation out-off the AB time-stepping.
315     Unfortunately, affects truncation error. Update output of exp. that "fails"
316      (cg2d matching number) and leave the others for later: front_relax(10),
317      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
318      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
319    
320    checkpoint57o_post
321    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
322      (2) its ready to be documented during the 20050801 DocFest
323    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
324      for ideal_2D_oce and lab_sea on linux_ia32_g77
325    o set to #undef CTRL_SET_OLD_MAXCVARS_30
326      in global1x1_tot/code_seaice_adj to access indices 32, 33
327      (worth another tag)
328    
329    checkpoint57n_post
330    o adding precip control xx_precip 32
331    o adding swflux control xx_swflux 33
332    o Replacing 10 forcing penalty cost routines by 1 generic.
333    o Implementing partitioning in time-mean and variable adjustment
334      for atmos. state.
335    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
336    o in natl_box_adjoint:
337      * updated exp 1 to 10
338        (but does not have time-mean vs. variable split results yet)
339    o updated global1x1/*_seaice_adj/
340      to incorporate latest changes
341    o enable useSingleCpuIO for mdsio vector routines
342      (applies in particular to tapelev I/O)
343    o removed inefficient K-loop in all active_file*control*.F
344    
345    checkpoint57m_post
346    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
347      and advect_cs (use EXCH-2 and standard cs-32 grid files).
348    o pkg/exch2: filling of face-corner halo regions is optional
349      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
350    
351    checkpoint57l_post
352     tag before updating tutorials (pre-release-2)
353    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
354       for output and interpolation of input fields onto model grid)
355    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
356       Affects results of exp. rotating_tank ; update output.txt.
357    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
358          and taking the square quantity and/or using a fraction-weight field.
359    o fix aim_diagnostics_init.F mate numbers.
360    o add mnc output capability to diagnostics/diagstat and update
361      our cvsignore files for the ACSII output generated
362    
363    checkpoint57k_post
364    o lab_sea now uses diagnostics package and provides a suite of
365      new EXF diagnostics output.
366    
367    checkpoint57j_post
368    o exf
369      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
370        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
371        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
372      * extended diagnostics output
373        - now includes all EXF variables
374        - hs, hl moved to common block
375        - separate S/R for diagnostics, called after ctrl vector is added
376        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
377        - EXFqnet contains true Qnet (i.e. includes qsw)
378      * updated verif. lab_sea, global_with_exf
379      * Rearranging hflux (exf_mapfields -> exf_getforcing)
380        to ensure that diagnostics sees a true EXFqnet
381    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
382    o diagnostics pkg: change pointers so that 1 diagnostic can be used
383      several times with different frequencies.
384    o mnc-ify the thsice package as requested by Daniel Enderton
385      - the monitor--MNC output needs work
386      - many attributes need to be added (most are currently blank)
387    o mnc-ify theaim_v23 package as requested by Daniel Enderton
388      - many attributes need to be added (most are currently blank)
389    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
390    o add Sadourny like discretization to the 4th.O vorticity advection scheme
391    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
392      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
393         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
394    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
395     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
396    
397    checkpoint57i_post
398    o Diagnostics package was changed: diagnostic allocation is now deactivated
399      by setting an empty file name in the namelist (used to be by setting 0 frequency)
400    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
401      add 1rst Order upwind vertical Shear.
402    o add a quick fix for A/B checkpointing in OFFLINE mode
403    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
404      end-run around the C/Fortran linking horror in eesup/src/timers.F
405    o added pkg/runclock: allows user to terminate run based on wall clock
406    o added non-hydrostatic scaling parameter: nh_am2
407    o pkg/my82: futile attempt to make results compiler-independent by adding
408      some "_d 0", etc. no effect.
409    o for mnc output, fill the 'T' coordinate var with myTime and create a
410      separate 'iter' variable for iteration count
411    o pkg/diagnostics:
412      add new capability: output of Global/Regional & per-level statistics ;
413      tested against monitor output (including land & thSIce) on various exp.
414    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
415    
416    checkpoint57h_done
417      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
418      data.diagnostics, data.gchem, data.ptracers) is done.
419    
420    o pkg/diagnostics: prepare for Global/Regional statistics.
421      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
422    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
423      and rename it: DIFFERENT_MULTIPLE
424    
425    checkpoint57h_post
426    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
427    o pkg/diagnostics: change output frequency, now in seconds (instead
428      of Nb of iterations). This requires to change data.diagnostics.
429    checkpoint57h_pre
430    
431    o in mnc, let the user create the output dir if both mnc_outdir_date
432      and mnc_outdir_num are false
433    o add fflags() to pkg/diagnostics which allows one to specify, on a
434      per-file basis, the file precision [default behavior is unchanged]
435    o added diagnostics to pkg/kpp, including computation of mixed layer
436      depth based on a temperature/density criterion
437    o updated verification/natl_box to test the new pkg/kpp diagnostics
438    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
439    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
440    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
441      not mnc -- this mistake was found by JMC and is now corrected
442    
443    checkpoint57g_post
444    o add Adams-Bashforth 3rd Order time stepping:
445      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
446      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
447    checkpoint57g_pre
448    
449    o make lambda[Theta,Salt]ClimRelax spatially varying
450      (default remains spatially uniform constant based on tau)
451    o added new control variables
452      * init. uVel, vVel, etanN
453      * lambda[Theta,Salt]ClimRelax
454    o separate masks used for ctrl_pack/unpack 'from write_grid' output
455      (suggested by G. Forget)
456    
457    checkpoint57f_post
458    o add parameter "baseTime" = model base time = time at iteration zero
459      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
460      account for baseTime shift
461    o move Coriolis arrays from PARAMS.h to GRID.h
462    checkpoint57f_pre
463    
464    o mnc-ifying the seaice package
465    o introduced an alternative length scale calculation for use in the limiting
466      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
467    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
468    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
469      as well as grad(vort3).  Made it compatible with both approximate form
470      for the cubed sphere and full form of these gradients.  Added flag
471      useFullLeith to select between approximate and full form.  
472    o add "d0" in getcon.F to reduce differences between compilers/platforms
473      update output.txt of exp. fizhi-gridalt-hs
474    o change port_rand funtion to allow to set the seed.
475    o fix obscure MNC bug involving conversion between reals and integers
476      - it caused no problems with certain (eg. gcc, ifc) compilers but the
477        new version is now more standards-compliant
478    o adjoint-related modifications
479      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
480      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
481      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
482    
483    checkpoint57e_post
484    o Adding eddy stress controls a la Ferreira et al.
485    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
486    
487    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
488      update output.txt of exp. fizhi-gridalt-hs
489    o add more "Z" dimensions and associated coordinate vars to MNC
490    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
491    o parameter calendarDumps: when set, approximate months (30-31 days) and years
492      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
493      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
494      months and years.  Requires pkg/cal.
495    o diagnostics: add pickup functionality
496      - off by default for backwards compatibility
497      - current version only uses MDSIO -- MNC will be added
498    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
499    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
500    
501    checkpoint57d_post
502    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
503    o modify verification/ideal_2D_oce so that it tests the creation of mnc
504      output from the diagnostics package
505    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
506    o make genmake2 more portable by using ".$FS" instead of ".f" for more
507      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
508    o add coordinate variables to the MNC output from the diagnostics package
509    o change MNC-flags default value: true when useMNC=TRUE
510    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
511      the ability (off by default) to read the grid information using MNC
512    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
513    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
514    o do snap-shot diagnostics at the middle of the time-interval (instead of
515      at the end).
516    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
517      new test for AIM with thSIce + slab-ocean
518    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
519    o move state variable diagnostics to the beginning of the time step ;
520      (note: still needs some work specially for snap-shot diagnostics)
521      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
522    
523    checkpoint57c_post
524    o Change testing option (-ieee) to get closer agreement between g77 & ifort
525    o generate new output.txt files on faulks with g77 & the new -ieee option
526    checkpoint57c_pre
527    
528    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
529      update output.txt of exp. global_ocean.90x40x15
530    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
531      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
532    o add saltFlux(+File) forcing capability with periodicExternalForcing
533    o allow to use pkg diagnostics for GM-Redi & ThSIce output
534    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
535    o improvements for the MNC output from DIAGNOSTICS:
536      - correct handling of the unlimitied dimension
537      - all dims now have associated coordinate variables
538      - variables located at U, V, and Corner ("Z") points are now written
539        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
540        *all* data points are output
541    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
542    o added pkg/seaice/seaice_monitor.F
543    o mdsio_readfield.F can now read files visible only to master MPI process.
544    o pkg/seaice: some test code for ice-modified ocean stress
545    o exf_getffields interpolation defaults to bilinear for all scalar forcing
546      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
547      spurious negative numbers for precipitation and humidity.  Will cause
548      some small numerical differences for integrations using pkg/exf/exf_interp.F.
549    o pkg/ctrl/
550      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
551        May be enabled via doPackDiag
552      *  introduce z-scaling of
553         + gradient (doZscalePack) and
554         + control (doZscaleUnpack)
555    o pkg/mdsio/
556      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
557      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
558    
559    checkpoint57b_post
560    o simplify options in diagnostics_fill arguments (remove weird combinations)
561    o fix MNC coordinate variables so that they now contain per-face index
562      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
563      general, EXCH2 grids are only aligned to a "local" coordinate system
564    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
565    o Implement instantaneous output within pkg diagnostics:
566      setting a negative frequency in data.diagnostics produces
567     "snap-shot" output (as opposed to time-average if freq > 0)
568    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
569      NOTE: change ptracer diagnostics name: use 2 characters to work with
570            more than 9 tracers. Add also diagnostics of advect & diffus flux.
571    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
572      becomes the coordinate variable for the 'T' dimension
573    o add CF-style coordinate variables to MNC
574      - just a first cut:  numbers are meaningless on the cubesphere and
575        missing along the T axis but otherwise it works!
576    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
577    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
578    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
579      this is based directly on what the model compute, so that the content of
580      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
581    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
582    o clean up build options files for SunOS, in particular
583      - remove -traditional from xmakedepend
584      - change -xarch=v9 to -xarch=native for f77
585      - restore use of make (not gmake)
586      - add CC=gcc if using g77
587    o changes per discussion of AM, JMC, & EH3 today:
588      - move redundant "grid" variables out of "state" -- in preparation of
589        creating proper CF-style coordinate variables and in recognition
590        that any/all grid variables can be easily copied (eg. w/NCO) from
591        the grid files into any of the other NetCDF files
592      - *always* output grid variables with MDSIO (this will eventually be
593        changed)
594      - output MNC grid file if useMNC is true
595    o every instance of _END_MASTER() has been found and replaced with
596      _END_MASTER( myThid ) in order to satisfy certain picky Sun
597      preprocessors
598    o re-arrange diagnostics pkg initialisation:
599     - allow each package to extend the available diagnostics list
600     - add some checking and fix small problems (multi-threaded, ...)
601     - new S/R diagnostics_fill (replace fill_diagnostics):
602       look through the short list of active diag. (instead of the long list)
603       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
604    
605    checkpoint57a_post
606    o this set of changes restores TAMC compatibility
607      tested for global_ocean.90x40x15 adjoint on trough
608      (what a pain)
609    
610    checkpoint57a_pre
611    o some modifs in tools/build_options for sunos
612    o call ctrl_pack for ctrl at end for optimcycle=0
613    
614    checkpoint57
615    o add horizontal bi-harmonic viscosity for vertical velocity
616      - new parameter viscA4W (defaults to viscA4)
617      - affects only non-hydrostatic code
618      - to be done: no-slip lateral boundary conditions
619    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
620    o implement Implicit Vertical advection for pTracers
621    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
622      (implemented also for implicit vertical diffusion & advection)
623    o OBCS: extend application of tracer open boundary conditions
624      to a strip beyond the boundary of width Olx/Oly
625    o add call monitor to TAF set of required calls (flow directives)
626      and include in natl_box_adjoint
627    o untangle a few ifdefs related to cost, ctrl, autodiff
628      untangel a few ALLOW_ECCO_OPTIMIZATION
629    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
630      (theta2, salt2 in ecco_cost_weights)
631    
632    checkpoint56c_post
633    o OBCS as control variables
634      - update ctrl_ad_diff.list, obcs_ad_diff.list
635      - remove balance of obcs controls from default
636      - fix index bug nobcs in ctrl_init
637      - fix dummy fields filen in ctrl_pack
638      - add dummy weights for obcs
639    o lsopt: comment out fort.94 output
640    o optim:
641      - remove unnecessary header files
642      - adjusted namelists
643      - add xerbla.F to Makefile
644    o exf:
645      - multiple modifications of exf_check_range
646      - unit change in exf_init_runoff from [m/year] to [m/s]
647    o mdsio:
648      - i/o-vector change debugLevel from debLevA to debLevB
649    
650    checkpoint56b_post
651    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
652      is called from DO_THE_MODEL_IO
653      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
654      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
655      - clean up PTRACERS_WRITE_TIMEAVE a little
656    o add another verification experiment that tests both the cfc-pkg and
657      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
658      reactive tendencies treated inline with regular timestepping
659    o testreport previously did a lousy job of comparing small numbers, so
660      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
661      implemented in the little c-progam tmp_cmpnum.c which is embedded in
662      testreport.
663    o ptracers_monitor: bug fix for MPI
664    
665    checkpoint56a_post
666    o GCHEM: finish reorganizating the package
667      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
668        (introduces another 3D-array for each passive tracer, but only if
669        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
670        gchemTendency is not needed because the timestep is done separately)
671      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
672      - GCHEM is now---more or less cleanly---separate from PTRACERS
673      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
674        so clear to me how that should be done in a general way.
675    o CFC: improve formatting of output in CFC_ATMOS
676    o PTRACERS:
677      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
678        that ALL experiments with ptracers enable can be checked. This makes
679        GCHEM_MONITOR obsolete.
680      - include a runtime parameter PTRACERS_monitorFreq that defaults to
681        monitorFreq
682      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
683    o add PTRACERS (PTR0[1-5]) to testreport output
684    o exf_check_range:
685      * default changed to .TRUE.
686      * will check values for niter0 if debLevA, every timestep if debLevB
687      * STOP in exf_check_range if 'out of range'
688      * range chosen generous to allow for potential extema
689      TBD: a version with stricter range
690           permitted range would be runtime parameters
691  o GMredi:  o GMredi:
692    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
693    - 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.

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