5      ==============================      ==============================
6    
7    
8    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
9    
10    checkpoint58p_post
11    o obcs: stop if obcs is used with useCDscheme = .true.
12    o shelfice:
13     - fix a sign error so that no slip at shelfice interface works
14     - remove stop for combination non-hydrostatic code and shelfice. That does
15       not mean, that the results are correct, but at least they are numerically
16       stable
17    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
18    o added adjoint exch routined for all exch*3d* routines
19      and updated flow directives
20    
21    checkpoint58o_post
22    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
23      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
24    o change controling S/R for writing pickup file (new S/R do_write_pickup)
25      and clean-up reading/writing of pickup files.
26    o fix local version of read/write pickup (NH part) in rotating_tank/code
27    o simplify EXCH interface:
28     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
29     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
30    o added the regrid package
31    o shelfice:
32     - add a simple boundary layer scheme to reduce noise
33     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
34    
35    checkpoint58n_post
36    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
37       local variable (not in common block).
38    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
39      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
40      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
41        to work with SingleCpuIO.
42    o add "_d 0" to real constant of pkg/cfc subroutines ;
43       update exp. cfc_exemple & tutorial_cfc_offline output files.
44    o multi-threading and IO:
45      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
46        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
47      - barrier before and after reading.
48      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
49      - avoid using MDS_WRITELOCAL for LAND pkg output.
50      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
51        common-block variables ; Allows multi-threading with master-thread IO.
52    o change default MAX_NO_THREADS from 32 to 4 ;
53      and stop cleanly when MAX_NO_THREADS is too small.
54    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
55    
56    checkpoint58m_post
57    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
58       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
59    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
60       keep global_ocean.90x40x15 (for AD testing) with former secondary test
61       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
62    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
63        add MITgcm_tutorials (= code + all the tutorials)
64    o ecco, option to compute cost for total ssh (mean+anom)
65    o consistent with addition of ptracer and ssh in pkg/profiles
66    o profiles: adding ptracer and ssh
67    o testreport: change multi-test output-file name
68      (from output.txt.{name} to output.{name}.txt)
69    o profiles: now ok for mutli-tiles case
70    o seaice: add 4 parameters for different advection schemes for area,
71      (effective) seaice thickness, enthalphy, and snow height. Their default
72      is the standard parameter SEAICEadvScheme
73    o calc_gw:
74     - add cosFacU in zonal viscous flux (harmonic.visc.).
75     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
76       of tutorial_plume_on_slope.
77    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
78    o calc_gw: true flux-form, account for horizontal grid spacing.
79      update rotating_tank results, but not plume_on_slope (affected at
80      truncation level, 11 digits).
81    
82    checkpoint58l_post
83    o calc_gw:
84     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
85     - remove side-drag for now (need to fix it); update plume_on_slope results.
86     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
87    o commit code to make SST/SSS weights spatially variable
88      (based on either variable in-situ or variable initial T/S weights)
89    o pkg/ecco:
90      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
91        now based on horizontally varying weights wthetaLev, wsaltLev
92      * cost_averagesflags now returns year indices in addition to day, month
93      * sflux balance is performed on annual basis
94        (sflxumm, sfluxmm2, bal_sfluxmm)
95      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
96        including separate counting and multipliers
97    o pkg/rbcs
98      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
99    
100    checkpoint58k_post
101    o testreport:
102     - always build in dir. "build" (if not there, mkdir build instead of building
103       & running in input)
104     - run in dir run (if it exists), in build otherwise.
105     - call prepare_run (if input/prepare_run exists)
106     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
107    o pkg/exf modifications to interpolation and rotation routines for more
108       reasonable treatment of North Pole singularity: for tracers North Pole
109       value is set to northernmost zonal-mean value, for zonal velocity it is
110       set to zero, and for meridional velocity it is set to northernmost value.
111    o pkg/exf/exf_check_range.F
112     - add tile index to diagnostics and move stop statement to the very
113       end of the routine.
114    o pkg/diagnostics: (diagnostics_main_init.F)
115      define title of isomorphic variables according to the current config.
116    o pkg/thsice with pkg/seaice dynamics:
117    - fix domain of computation (interior only, required for exf) and do exchanges
118    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
119    o towards a standard way of dealing with multi-threading in MONITOR
120      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
121    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
122       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
123    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
124    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
125    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
126       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
127    o tracer advection:
128     - clean-up and simplify calc_common_factors.F
129     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
130       advection subroutine (but still not used within DST advection S/R)
131    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
132    
133    checkpoint58j_post
134    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
135      from file (collects calls previously in FORWARD_STEP)
136    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
137    o adjoint store dir. adjusted accordingly
138    o genmake2
139      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
140    
141    checkpoint58i_post
142    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
143      on wind stress (SEAICEstressFactor defaults to 1.)
144    o Total number of Timers is finite (<=40): comment out 2 non-essential one
145      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
146    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
147      on CS-grid: no longer loosing mass.
148    o exf & curvilinear-grid: no longer modify longitude xC & xG.
149    o pkg/ggl90: fix sloppy output and fix a bug
150    o pkg/seaice: added SEAICEuseEVPpickup parameter
151      - Set to false in order to start EVP solver with
152        non-EVP pickup files when using SEAICEuseEVP
153      - fix sign error in diffusion in seaice_calc_rhs
154    
155    checkpoint58h_post
156    * Modifications for bottom topography control
157      o replace hFacC by _hFacC at various places
158      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
159      o add non-self-adjoint cg2d_nsa
160      o update autodiff support routines
161      o re-initialise hfac after ctrl_depth_ini
162      o works for 5x5 box, doesnt work for global_ocean.90x40x15
163    * Adding verification for 5x5 box (4-layer) bottom topography control
164    
165    checkpoint58g_post
166    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
167       used for mean seasonal cycle, mean diurnal cycle); add an example
168       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
169    o pkg/ggl90:
170      - add parameter (minimum surface kinetic energy)
171      - fix bug (avoiding division by zero)
172    o couple pkg/thsice to pkg/seaice:
173      - modify advection in seaice to accomodate new scalar fields to be advected
174      - only muliDimAdection scheme work with seaice/thsice
175      - mapping of thsice-variables to seaice-variables, back and forth
176      - does not break the verification experiments, but does not give the
177        desired results either
178    o pkg/seaice
179      - make (default) second order advection a bit less confusing?
180    
181    checkpoint58f_post
182    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
183      to pkg/seaice):
184      - new routines thsice_map_exf and thsice_get_exf provide the interface
185      - add an additional formal parameter to thsice_solve4temp
186    o pkg/exf:
187      - add new fields wspeed, snowprecip (to be able to couple to thsice)
188      - correct Stefan-Boltzmann constant
189      - new parameter for longwave surface emittance
190      - separate some stuff from exf_bulkformulae into new routines  
191        exf_radiation, exf_wind
192      - add new parameters and constants: longwave emissivity for ocean, ice
193        and snow, evaporation parameters over ice
194      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
195        either wind from stress or stress from wind
196    o pkg/thSIce:
197    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
198    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
199       and THSICE_CALC_THICKN
200    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
201    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
202      to make debugging easier.
203    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
204    o pkg/bulk_force:
205      - clean-up comments and parameters ;
206      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
207    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
208      generate new output for test-experiment: aim.5l_cs.thSI
209    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
210      testreport accordingly
211    
212    checkpoint58e_post
213    o SEAICE_CGRID adjoint done
214    o R_STAR adjoint implemented.
215      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
216      * need to sort out init. of h0facc, etc.
217    o Make pkg/profile fully independent of ecco,cost, etc. stuff
218      to be able to use it in pure forward.
219    
220    checkpoint58d_post
221    o upgrade simple test-experiment to tutorial example:
222     step.1: duplicate the experiment and (step.2) will remove the old copy.
223      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
224      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
225      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
226      tutorial_global_oce_biogeo    <- copy of dic_example
227      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
228      tutorial_plume_on_slope       <- copy of plume_on_slope
229      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
230      tutorial_global_oce_optim     <- empty for now (David ?)
231      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
232     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
233    o correct a sign problem in cost_scat.F
234    o obcs and ptracers: fix boundary conditions for advections schemes
235      with larger stencil
236    o thsice adjoint: start
237    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
238      completeness
239    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
240      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
241    o ptracers adjoint:
242      * avoid extensive recomputatations
243      * fix missing re-init. of gptr (missed by TAF)
244    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
245      me to turn off the excessive output to STDOUT that this package produces
246    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
247      and add those terms in Vector-Invariant formulation.
248    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
249      if the control period (xx_hfluxperiod etc) is 0
250    o in profiles pkg, clean routines and fix details
251    o in ecco pkg, reading ssh data:
252      fix problem in case the model does not start at iter0=0
253    o fix mnc-pickup/restart for ptracers
254    o new package prifiles:
255      code to compute profile-based cost by Gael Forget
256      (modifs in ecco, ctrl, autodiff)
257    o Benign bug fix in initialization (spotted by M. Mazloff) of
258      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
259    
260    checkpoint58c_post
261    o adjoint: finish NLFS adjoint and provide reference output in
262      verification/global_ocean.90x40x15/results_ad_nlfs
263    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
264      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
265      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
266      with SEAICE_CGRID defined.
267    o move calendarDumps from "data" to "data.cal" and clean-up the code
268      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
269    o add useEXF & useCAL flags (for now, set in hard-coded way)
270    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
271      (were missing in NH mode, and wrong in quasihydrostatic mode).
272      waiting for Chris updated version of calc_gw to add those CALLs.
273    o fix bug in quasihydrostatic S/R ;
274      add a test for this option: global_ocean.90x40x15.qshyd
275    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
276      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
277    o add on/off flag useOffLine for package OFFLINE
278    o seaice:
279      - modify advection so that it works also on the C-grid
280      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
281        problem in multi-tile runs with C-grid
282      - add flags for clipping ice velocities and/or masking solver forcing
283      - fix drag (ocean on ice) formulation and a bug that caused noise in the
284        C-grid solver
285      - added a few comments to seaice_diffusion.F
286      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
287        are now exclusive)
288      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
289        required re-ordering the code a little:
290       + make DAIRN global variable (defined in SEAICE)
291       + move computation of the viscosities eta and zeta into a new separate
292         routine (because I need to recompute them in seaice_ocean_stress.F)
293    
294    checkpoint58b_post
295    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
296      update output.txt of exp. aim.5l_cs.thSI
297    o various mnc cleanups and improvements:
298      + shrink lookup tables by factor of ~4
299      + better error reporting when running out of lookup space
300      + able to handle longer path/file names (up to 500 chars)
301    o adjoint:
302      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
303      - TBD: "hidden" mom_vecinv recomp. in dynamics
304    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
305     (allow to differentiate between forcing components using new integer flags:
306      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
307     and add new flag to put Dissipation tendency out of Adams-Bashforth.
308    o ecco
309      - enable trend removal from SSH anomaly obs.
310    o adjoint
311      - a fix for PmEpR when #undef EXACT_CONSERV
312      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
313      - try to fix "hidden" recomp. in forward_step for NLFS
314        (NLFS seems broken sometimes after I checked it in)
315    o seaice:
316     - add c-grid version of the dynamic solver:
317       + three new routines that are the c-grid substitute lsr, dynsolver
318         and ostres
319       + put a few fields that were local to dynsolver into global common
320         blocks, so that I can move the computation of stresses etc into
321         seaice_lsr (saves coding but may break the adjoint).
322     - replace more hardwired parameters by runtime parameters
323     - add ice masks that mask the rhs of the implicit solvers where there
324       is no ice (commented out in seaice_dynsolver, because i am not sure
325       if this works properly), eventually this should replace the clipping
326       of ice velocities in seaice_dynsolver to +/-40cm/s.
327    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
328      include it only where its needed
329    o move balancing of fluxes before the call of external_forcing_surf
330    o seaice:
331      - correct units of turning angles (now they are really in degrees)
332      - move computation of GWATX/Y out of main routine into dynsolver
333      - initialize GWATX/Y in seaice_init
334    o Apply mask on Fresh-Water flux (needed for SSH forcing).
335      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
336    o seaice: add runtime flags for turning angles (default to zero)
337    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
338      and trend from exf forcing and ctrl control adjustments
339    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
340      (since checkpoint57x_post)
341    o change the default rotation period to 86164.s = the Earth rotation
342    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
343      and based on a reference stratification. Tested within hs94.cs-32x32x5.
344    o seaice advection: add code for choosing between the default (2nd order
345      central differences) and multiDim advection schemes provided by
346      pkg/generic_advdiff
347    o seaice:
348      - removed all references to SEAICE_GRID.h fields from
349        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
350        (cubed-sphere configuration will change a little)
351      - grid computations in seaice_init are obsolete now.
352      - cleaned up code a little so that is easier to read (hopefully).
353      - added new (better?) discretizations of default advection and diffusion
354        (turn on with SEAICEuseFluxForm)
355      - replace 1 in 3d global fields by kSurface in growth.F
356      
357    checkpoint58a_post
358    o seaice:
359      - bug fix in advect.F
360    o shelfice:
361      - separate shelfice load anomaly from pload (breaks with time
362        dependent forcing), => introduce constant field shelficeLoadAnomaly.
363        Its default is 0., but it may be computed more cleverly from (unknown)
364        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
365        done offline. A good approximation of the pressure load anomaly is
366        necessary to avoid large initial adjustment processes underneath
367        deep-reaching shelfice.
368      - small fix in ISOMIP shelfice_thermodynamics
369      - add more sophisticated thermodynamics of Hellmer (1989), this is
370        now the default
371      - give a few constants more intuitive names
372    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
373      if bulk formulae are used in long integration (especially EmPmR). Turn
374      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
375      if balancePrintMean, the imbalance that is substracted is printed to
376      STDOUT.
377    o fix bug (typo) in obcs_apply_eta.F
378    o add a new package shelfice which enables us to model the circulation
379      underneath shelf-ice with draughts of hundreds of meters.
380     - works
381     - to do: + include improved thermodynamics
382              + check whether kSurfC (from model/inc/SURFACE.h) can be used
383                instead of new field kTopC
384              + can we use topoFile, Ro_surf and existing code in ini_depth.F
385                instead of new field R_shelfIce and new code in ini_depth.F
386                and ini_mask_etc.F?
387              + adjust vertical mixing schemes?
388    o seaice pkg:
389     - add a cpp-flag to include a simple formula for a salinity dependent
390       freezing point of sea water at the surface
391     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
392       meridional stresses are now different (and hopefully correct)
393    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
394       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
395       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
396    o pkg/diagnostics: add options and parameters for regional-statistics
397       diagnostics ; define regions by reading a region-mask from a file
398       (might add other options later)
399    o pkg/bulk_force:
400     - add option and parameters to use AIM surface-flux formulae.
401     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
402       others forcing fields (defined in PARM05, parameter file "data") are loaded
403       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
404     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
405     - use the right EXCH call for uwind,vwind (to work on CS-grid).
406     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
407       and parameters (note: calcWindStress replaces .NOT.readwindstress).
408     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
409    
410    checkpoint58
411    o add "--embed-source" option to genmake2 which, when the supporting
412      tools can be compiled (as determined by genmake2) will turn on the
413      embed_files package which then embeds the entire MITgcm source code
414      (*.[fFhc] + Makefile) used for the build within the executable
415      - requested by CNH but off by default
416      - adds a paltry <9MB to the mitgcmuv executable in most cases
417      - only writes the output when useEMBEDSRC in eedata is true
418    o clean up 3-dim. relaxation codes:
419      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
420      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
421      * Thanks to Tom Haine for testing!
422    
423    checkpoint57z_post
424    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
425      affects output (@ truncation level) of exp. plume_on_slope ; updated.
426    o fix the pickup behavior for obcs in combination with ptracers
427    o fix a bug in ptracers_external_fields_load
428    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
429      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
430    o transfered surface NH pressure to eta field (if exactConserv).
431    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
432         and update lab_sea output.txt file.
433    o completing 3-dim. relaxation code: additional term
434         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
435      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
436      * At compile time, in "EXF_OPTIONS.h" set
437          #define  ALLOW_CLIMTEMP_RELAXATION
438          #define  ALLOW_CLIMSALT_RELAXATION
439      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
440          tauThetaClimRelax3Dim = 15552000.0,
441          tauSaltClimRelax3Dim  = 15552000.0,
442      * 3 cases:
443          1) Use a constant-in-time 3-dim. field
444          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
445          3) Real-time relax. to time-evolving prescribed field
446    o Adding Laplacian-type smoothness constraint on
447      initial and boundary (forcing) controls (ic, bc)
448      * enable at compile-time via
449        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
450      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
451      * Absolute scale somewhat unclear so far
452      * no area weighting was included since no other cost term does so far
453    
454    checkpoint57y_post
455    First step for a NLFS adjoint
456    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
457    o new init. routines for calc_r_star, calc_surf_dr
458    o still need to deal with ini_masks_etc
459    o testreport seemed happy
460    checkpoint57y_pre
461    
462    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
463    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
464    o add new offset feature to offline pkg (plus minor cleanup)
465    o cfc fixes for final year of integration
466    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
467      be in GCHEM_OPTIONS).
468    
469    checkpoint57x_post
470    o fix testreport Pb in multiple test experiment.
471    o cleanup our namelist syntax in verification:
472      - make it more F95 standards compliant (some work still needed)
473      - allows the vast majority of our tests to work with gfortran
474    o Non-Hydrostatic:
475     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
476     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
477    o Allow to apply AB on T,S rather than on AB(gT,gS):
478     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
479     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
480       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
481     - need a "clever" read_pickup to restart from the other AB formulation
482    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
483    o remove some unused variables (reduces number of compiler warnings)
484    o adjoint
485      * Disable useVariableViscosity for adjoint for time being
486        (there are a number of extensive recomputations)
487      * Initialize certain variables needed for adjoint
488    
489    checkpoint57w_post
490    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
491                 fix the singleCpuIO RS version of MDSWRITEFIELD
492       and add a WARNING if using globalFiles=T with multi-processors.
493    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
494      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
495    o tracer advection scheme:
496      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
497       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
498       was not very convenient).
499      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
500       (further tests needed for the implicit DST & Flux-Limiter schemes).
501    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
502      and sRef for convenience, handy, when you want to initialize
503      ptracers in a large domain with a constant non-zero value. Also,
504      untangle ptracers_init.F a little.
505    
506    checkpoint57v_post
507    o change dome exp. to use variable viscosity in side-drag terms.
508    o remove all the files from the cfc_offline test since they are now
509      incorporated into tutorial_cfc_offline which has been producing
510      identical results for a few days of testing
511    o add new parameter: sideDragFactor to enable half-slip-side BC
512      and change side-drag S/R to use viscosity from mom_calc_visc
513      (can switch back by setting sideDragFactor=0.); affects results at
514      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
515       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
516    o vorticity & strain are now computed without masking, to account for
517      no-slip-side BC in variable viscosity calculation ; mask is applied
518      anyway later on, before computing advection/coriolis terms.
519    o modify exp4 to test new obcs support for reading from external files
520      and for passive tracers
521    o fix behavior of ptracers_monitor when monitor output is written to a
522      netcdf-file; still not independent of monitor.F (writes in the same
523      file).
524    o change default value of tRef (put a uniform, meaningful value for ocean
525      & atmos) and initialize sRef (was missing, as Martin mentioned).
526    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
527      to be proportional to enstrophy dissipation length.  Thus,
528       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
529      This is now consistent with Smagorinsky and with the manual.
530    
531    checkpoint57u_post
532    o OBCS and PTRACERS: add open boundary support for passive tracers
533      - either use homogenous (pseudo) v.Neumann conditions or prescribe
534        OB-values from file; this is not different from the way theta and salinity
535        are treated
536      - however, Orlanski-radiation conditions are not supported, and the model
537        will stop if you use pTracers and Orlanski at the same time.
538      - beefed up the rountine obcs_external_fields_load: now only those open
539        boundary values are overwritten with values from files for which there
540        are really files, otherwise the OB-fields remain untouched. This makes
541        it possible to use different OBs at different ends of the domain (as
542        with EXF)
543    o reduce number of exch calls in shap_filt (s2).
544    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
545      truncation level) 4/5 MLAdjust test results (11&12 digits match).
546    
547    checkpoint57t_post
548    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
549    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
550      same truncation, independent of the face number: affects affects several
551      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
552    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
553      note that biharmonic viscosity + no-slip was not tested in any experiment.
554    o fix bug in non-linear free-surf side-drag ; generate new output for
555      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
556    o make mnc honor the writeBinaryPrec flag for most kinds of output
557    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
558    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
559      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
560    o add brackets in multi-terms sum to get same truncation, independent of
561      the face number (manage to get exactly same value of gU,gV at the cs-edge)
562      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
563    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
564      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
565      a maximum grid-scale Reynolds number.  Also, changes all length calculations
566      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
567      Suggested values of viscosity parameters found in mom_calc_visc.
568      Many new viscosity diagnostics available.
569    
570    checkpoint57s_post
571    o Add clearing-house for viscosity calculations, mom_calc_visc and
572      correct numerous bugs in LeithD and Smagorinsky discretizations.  
573      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
574      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
575      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
576      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
577      The Strain-Tension form is now called with useStrainTensonVisc=.true.
578      ViscAhStrain and viscAhTension are now retired.
579    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
580    o In response to JMC's bug report, genmake2 now ignores any soft-links
581      that it finds in the *current* directory when searching for files.
582      Soft-links found in any other source directories will still work as
583      they did before.
584    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
585      a C routine to unlimit the stack size
586    o mnc-ify pkg/aim snapshot vars
587    o mnc-ify pkg/land as requested by Daniel
588    o various changes to mnc including:
589      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
590      - output can now be grouped so that all files within a group
591          change the ITER portion of their names in lock-step together
592      - can now read ("global") PER-FACE (in addition to PER-TILE) files
593          and works with both EXCH1 and EXCH2 (but needs more testing)
594      - writing works for all verification test cases w/ g77 on Linux
595    
596    checkpoint57r_post
597    o make MNC variable initialization happen earlier
598    o add diagnostics for (almost) each term of the momentum Eq.
599    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
600    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
601    o remove MINIMAL_TAVE_OUTPUT option ;
602      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
603    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
604      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
605    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
606    o add time-dependent SST, SSS control
607    o cost terms in ecco/ modularized (new cost_generic.F)
608    o cost_averages routines are modularized (new cost_averagesgeneric.F)
609    o new infrastructure for seaice model vs. obs misfits in seaice/
610      * driver from the_main_loop.F is seaice_cost_driver.F
611      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
612      * gradient check in Exp. 6a of natl_box_adjoint/
613    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
614      (see README file)
615    
616    checkpoint57q_post
617    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
618    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
619      - bug was reported by Jean-Michel and Ian Fenty
620    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
621      update exp. cpl_aim+ocn output.
622    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
623      Needed for high-res. runs with large global files
624      to be able to limit tapelev size
625    o Changed some tests for adjoint:
626      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
627      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
628      * global_ocean.90x40x15/ back to default 3-level checkpointing
629    o Modifications to enable scripted COMMON to MODULE conversion
630      * verification/OpenAD/code/ has necessary scripts and description;
631      * converts, compiles and runs successfully;
632    
633    checkpoint57p_post
634    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
635    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
636      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
637    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
638    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
639      (was already the case for dissipation with mom_vecinv,
640       and also the case for grad.PhiHyd when staggered-timeStep)
641      This will allow to put dissipation out-off the AB time-stepping.
642     Unfortunately, affects truncation error. Update output of exp. that "fails"
643      (cg2d matching number) and leave the others for later: front_relax(10),
644      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
645      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
646    
647    checkpoint57o_post
648    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
649      (2) its ready to be documented during the 20050801 DocFest
650    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
651      for ideal_2D_oce and lab_sea on linux_ia32_g77
652    o set to #undef CTRL_SET_OLD_MAXCVARS_30
653      in global1x1_tot/code_seaice_adj to access indices 32, 33
654      (worth another tag)
655    
656    checkpoint57n_post
657    o adding precip control xx_precip 32
658    o adding swflux control xx_swflux 33
659    o Replacing 10 forcing penalty cost routines by 1 generic.
660    o Implementing partitioning in time-mean and variable adjustment
661      for atmos. state.
662    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
663    o in natl_box_adjoint:
664      * updated exp 1 to 10
665        (but does not have time-mean vs. variable split results yet)
666    o updated global1x1/*_seaice_adj/
667      to incorporate latest changes
668    o enable useSingleCpuIO for mdsio vector routines
669      (applies in particular to tapelev I/O)
670    o removed inefficient K-loop in all active_file*control*.F
671    
672    checkpoint57m_post
673    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
674      and advect_cs (use EXCH-2 and standard cs-32 grid files).
675    o pkg/exch2: filling of face-corner halo regions is optional
676      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
677    
678    checkpoint57l_post
679     tag before updating tutorials (pre-release-2)
680    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
681       for output and interpolation of input fields onto model grid)
682    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
683       Affects results of exp. rotating_tank ; update output.txt.
684    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
685          and taking the square quantity and/or using a fraction-weight field.
686    o fix aim_diagnostics_init.F mate numbers.
687    o add mnc output capability to diagnostics/diagstat and update
688      our cvsignore files for the ACSII output generated
689    
690    checkpoint57k_post
691    o lab_sea now uses diagnostics package and provides a suite of
692      new EXF diagnostics output.
693    
694    checkpoint57j_post
695    o exf
696      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
697        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
698        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
699      * extended diagnostics output
700        - now includes all EXF variables
701        - hs, hl moved to common block
702        - separate S/R for diagnostics, called after ctrl vector is added
703        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
704        - EXFqnet contains true Qnet (i.e. includes qsw)
705      * updated verif. lab_sea, global_with_exf
706      * Rearranging hflux (exf_mapfields -> exf_getforcing)
707        to ensure that diagnostics sees a true EXFqnet
708    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
709    o diagnostics pkg: change pointers so that 1 diagnostic can be used
710      several times with different frequencies.
711    o mnc-ify the thsice package as requested by Daniel Enderton
712      - the monitor--MNC output needs work
713      - many attributes need to be added (most are currently blank)
714    o mnc-ify theaim_v23 package as requested by Daniel Enderton
715      - many attributes need to be added (most are currently blank)
716    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
717    o add Sadourny like discretization to the 4th.O vorticity advection scheme
718    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
719      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
720         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
721    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
722     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
723    
724    checkpoint57i_post
725    o Diagnostics package was changed: diagnostic allocation is now deactivated
726      by setting an empty file name in the namelist (used to be by setting 0 frequency)
727    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
728      add 1rst Order upwind vertical Shear.
729    o add a quick fix for A/B checkpointing in OFFLINE mode
730    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
731      end-run around the C/Fortran linking horror in eesup/src/timers.F
732    o added pkg/runclock: allows user to terminate run based on wall clock
733    o added non-hydrostatic scaling parameter: nh_am2
734    o pkg/my82: futile attempt to make results compiler-independent by adding
735      some "_d 0", etc. no effect.
736    o for mnc output, fill the 'T' coordinate var with myTime and create a
737      separate 'iter' variable for iteration count
738    o pkg/diagnostics:
739      add new capability: output of Global/Regional & per-level statistics ;
740      tested against monitor output (including land & thSIce) on various exp.
741    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
742    
743    checkpoint57h_done
744      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
745      data.diagnostics, data.gchem, data.ptracers) is done.
746    
747    o pkg/diagnostics: prepare for Global/Regional statistics.
748      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
749    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
750      and rename it: DIFFERENT_MULTIPLE
751    
752    checkpoint57h_post
753    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
754    o pkg/diagnostics: change output frequency, now in seconds (instead
755      of Nb of iterations). This requires to change data.diagnostics.
756    checkpoint57h_pre
757    
758    o in mnc, let the user create the output dir if both mnc_outdir_date
759      and mnc_outdir_num are false
760    o add fflags() to pkg/diagnostics which allows one to specify, on a
761      per-file basis, the file precision [default behavior is unchanged]
762    o added diagnostics to pkg/kpp, including computation of mixed layer
763      depth based on a temperature/density criterion
764    o updated verification/natl_box to test the new pkg/kpp diagnostics
765    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
766    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
767    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
768      not mnc -- this mistake was found by JMC and is now corrected
769    
770    checkpoint57g_post
771    o add Adams-Bashforth 3rd Order time stepping:
772      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
773      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
774    checkpoint57g_pre
775    
776    o make lambda[Theta,Salt]ClimRelax spatially varying
777      (default remains spatially uniform constant based on tau)
778    o added new control variables
779      * init. uVel, vVel, etanN
780      * lambda[Theta,Salt]ClimRelax
781    o separate masks used for ctrl_pack/unpack 'from write_grid' output
782      (suggested by G. Forget)
783    
784    checkpoint57f_post
785    o add parameter "baseTime" = model base time = time at iteration zero
786      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
787      account for baseTime shift
788    o move Coriolis arrays from PARAMS.h to GRID.h
789    checkpoint57f_pre
790    
791    o mnc-ifying the seaice package
792    o introduced an alternative length scale calculation for use in the limiting
793      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
794    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
795    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
796      as well as grad(vort3).  Made it compatible with both approximate form
797      for the cubed sphere and full form of these gradients.  Added flag
798      useFullLeith to select between approximate and full form.  
799    o add "d0" in getcon.F to reduce differences between compilers/platforms
800      update output.txt of exp. fizhi-gridalt-hs
801    o change port_rand funtion to allow to set the seed.
802    o fix obscure MNC bug involving conversion between reals and integers
803      - it caused no problems with certain (eg. gcc, ifc) compilers but the
804        new version is now more standards-compliant
805    o adjoint-related modifications
806      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
807      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
808      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
809    
810    checkpoint57e_post
811    o Adding eddy stress controls a la Ferreira et al.
812    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
813    
814    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
815      update output.txt of exp. fizhi-gridalt-hs
816    o add more "Z" dimensions and associated coordinate vars to MNC
817    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
818    o parameter calendarDumps: when set, approximate months (30-31 days) and years
819      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
820      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
821      months and years.  Requires pkg/cal.
822    o diagnostics: add pickup functionality
823      - off by default for backwards compatibility
824      - current version only uses MDSIO -- MNC will be added
825    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
826    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
827    
828    checkpoint57d_post
829    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
830    o modify verification/ideal_2D_oce so that it tests the creation of mnc
831      output from the diagnostics package
832    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
833    o make genmake2 more portable by using ".$FS" instead of ".f" for more
834      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
835    o add coordinate variables to the MNC output from the diagnostics package
836    o change MNC-flags default value: true when useMNC=TRUE
837    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
838      the ability (off by default) to read the grid information using MNC
839    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
840    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
841    o do snap-shot diagnostics at the middle of the time-interval (instead of
842      at the end).
843    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
844      new test for AIM with thSIce + slab-ocean
845    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
846    o move state variable diagnostics to the beginning of the time step ;
847      (note: still needs some work specially for snap-shot diagnostics)
848      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
849    
850    checkpoint57c_post
851    o Change testing option (-ieee) to get closer agreement between g77 & ifort
852    o generate new output.txt files on faulks with g77 & the new -ieee option
853    checkpoint57c_pre
854    
855    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
856      update output.txt of exp. global_ocean.90x40x15
857    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
858      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
859    o add saltFlux(+File) forcing capability with periodicExternalForcing
860    o allow to use pkg diagnostics for GM-Redi & ThSIce output
861    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
862    o improvements for the MNC output from DIAGNOSTICS:
863      - correct handling of the unlimitied dimension
864      - all dims now have associated coordinate variables
865      - variables located at U, V, and Corner ("Z") points are now written
866        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
867        *all* data points are output
868    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
869    o added pkg/seaice/seaice_monitor.F
870    o mdsio_readfield.F can now read files visible only to master MPI process.
871    o pkg/seaice: some test code for ice-modified ocean stress
872    o exf_getffields interpolation defaults to bilinear for all scalar forcing
873      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
874      spurious negative numbers for precipitation and humidity.  Will cause
875      some small numerical differences for integrations using pkg/exf/exf_interp.F.
876    o pkg/ctrl/
877      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
878        May be enabled via doPackDiag
879      *  introduce z-scaling of
880         + gradient (doZscalePack) and
881         + control (doZscaleUnpack)
882    o pkg/mdsio/
883      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
884      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
885    
886    checkpoint57b_post
887    o simplify options in diagnostics_fill arguments (remove weird combinations)
888    o fix MNC coordinate variables so that they now contain per-face index
889      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
890      general, EXCH2 grids are only aligned to a "local" coordinate system
891    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
892    o Implement instantaneous output within pkg diagnostics:
893      setting a negative frequency in data.diagnostics produces
894     "snap-shot" output (as opposed to time-average if freq > 0)
895    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
896      NOTE: change ptracer diagnostics name: use 2 characters to work with
897            more than 9 tracers. Add also diagnostics of advect & diffus flux.
898    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
899      becomes the coordinate variable for the 'T' dimension
900    o add CF-style coordinate variables to MNC
901      - just a first cut:  numbers are meaningless on the cubesphere and
902        missing along the T axis but otherwise it works!
903    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
904    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
905    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
906      this is based directly on what the model compute, so that the content of
907      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
908    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
909    o clean up build options files for SunOS, in particular
910      - remove -traditional from xmakedepend
911      - change -xarch=v9 to -xarch=native for f77
912      - restore use of make (not gmake)
913      - add CC=gcc if using g77
914    o changes per discussion of AM, JMC, & EH3 today:
915      - move redundant "grid" variables out of "state" -- in preparation of
916        creating proper CF-style coordinate variables and in recognition
917        that any/all grid variables can be easily copied (eg. w/NCO) from
918        the grid files into any of the other NetCDF files
919      - *always* output grid variables with MDSIO (this will eventually be
920        changed)
921      - output MNC grid file if useMNC is true
922    o every instance of _END_MASTER() has been found and replaced with
923      _END_MASTER( myThid ) in order to satisfy certain picky Sun
924      preprocessors
925    o re-arrange diagnostics pkg initialisation:
926     - allow each package to extend the available diagnostics list
927     - add some checking and fix small problems (multi-threaded, ...)
928     - new S/R diagnostics_fill (replace fill_diagnostics):
929       look through the short list of active diag. (instead of the long list)
930       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
931    
932    checkpoint57a_post
933    o this set of changes restores TAMC compatibility
934      tested for global_ocean.90x40x15 adjoint on trough
935      (what a pain)
936    
937    checkpoint57a_pre
938    o some modifs in tools/build_options for sunos
939    o call ctrl_pack for ctrl at end for optimcycle=0
940    
941    checkpoint57
942    o add horizontal bi-harmonic viscosity for vertical velocity
943      - new parameter viscA4W (defaults to viscA4)
944      - affects only non-hydrostatic code
945      - to be done: no-slip lateral boundary conditions
946    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
947    o implement Implicit Vertical advection for pTracers
948    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
949      (implemented also for implicit vertical diffusion & advection)
950    o OBCS: extend application of tracer open boundary conditions
951      to a strip beyond the boundary of width Olx/Oly
952    o add call monitor to TAF set of required calls (flow directives)
953      and include in natl_box_adjoint
954    o untangle a few ifdefs related to cost, ctrl, autodiff
955      untangel a few ALLOW_ECCO_OPTIMIZATION
956    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
957      (theta2, salt2 in ecco_cost_weights)
958    
959    checkpoint56c_post
960    o OBCS as control variables
961      - update ctrl_ad_diff.list, obcs_ad_diff.list
962      - remove balance of obcs controls from default
963      - fix index bug nobcs in ctrl_init
964      - fix dummy fields filen in ctrl_pack
965      - add dummy weights for obcs
966    o lsopt: comment out fort.94 output
967    o optim:
968      - remove unnecessary header files
969      - adjusted namelists
970      - add xerbla.F to Makefile
971    o exf:
972      - multiple modifications of exf_check_range
973      - unit change in exf_init_runoff from [m/year] to [m/s]
974    o mdsio:
975      - i/o-vector change debugLevel from debLevA to debLevB
976    
977    checkpoint56b_post
978    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
979      is called from DO_THE_MODEL_IO
980      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
981      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
982      - clean up PTRACERS_WRITE_TIMEAVE a little
983    o add another verification experiment that tests both the cfc-pkg and
984      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
985      reactive tendencies treated inline with regular timestepping
986    o testreport previously did a lousy job of comparing small numbers, so
987      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
988      implemented in the little c-progam tmp_cmpnum.c which is embedded in
989      testreport.
990    o ptracers_monitor: bug fix for MPI
991    
992    checkpoint56a_post
993    o GCHEM: finish reorganizating the package
994      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
995        (introduces another 3D-array for each passive tracer, but only if
996        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
997        gchemTendency is not needed because the timestep is done separately)
998      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
999      - GCHEM is now---more or less cleanly---separate from PTRACERS
1000      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1001        so clear to me how that should be done in a general way.
1002    o CFC: improve formatting of output in CFC_ATMOS
1003    o PTRACERS:
1004      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1005        that ALL experiments with ptracers enable can be checked. This makes
1006        GCHEM_MONITOR obsolete.
1007      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1008        monitorFreq
1009      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1010    o add PTRACERS (PTR0[1-5]) to testreport output
1011    o exf_check_range:
1012      * default changed to .TRUE.
1013      * will check values for niter0 if debLevA, every timestep if debLevB
1014      * STOP in exf_check_range if 'out of range'
1015      * range chosen generous to allow for potential extema
1016      TBD: a version with stricter range
1017           permitted range would be runtime parameters
1018  o GMredi:  o GMredi:
1019    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1020    - 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.

1026      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1027        this flag is now only visible within GCHEM-pkg routines.
1028      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1029        be replaced by a 3D array that is computed before thermodynamics; for
1030        this, the tracer ID iTracer had to be included into the parameter list
1031        of ptracers_forcing
1032      - set up forward_step to call gchem_forcing, that will replace
1033        gchem_forcing_int in ptracers_forcing
1034      - cleaning up
