5      ==============================      ==============================
6    
7    
8    o shelfice:
9     - fix a sign error so that no slip at shelfice interface works
10     - remove stop for combination non-hydrostatic code and shelfice. That does
11       not mean, that the results are correct, but at least they are numerically
12       stable
13    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
14    
15    checkpoint58o_post
16    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
17      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
18    o change controling S/R for writing pickup file (new S/R do_write_pickup)
19      and clean-up reading/writing of pickup files.
20    o fix local version of read/write pickup (NH part) in rotating_tank/code
21    o simplify EXCH interface:
22     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
23     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
24    o added the regrid package
25    o shelfice:
26     - add a simple boundary layer scheme to reduce noise
27     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
28    
29    checkpoint58n_post
30    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
31       local variable (not in common block).
32    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
33      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
34      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
35        to work with SingleCpuIO.
36    o add "_d 0" to real constant of pkg/cfc subroutines ;
37       update exp. cfc_exemple & tutorial_cfc_offline output files.
38    o multi-threading and IO:
39      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
40        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
41      - barrier before and after reading.
42      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
43      - avoid using MDS_WRITELOCAL for LAND pkg output.
44      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
45        common-block variables ; Allows multi-threading with master-thread IO.
46    o change default MAX_NO_THREADS from 32 to 4 ;
47      and stop cleanly when MAX_NO_THREADS is too small.
48    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
49    
50    checkpoint58m_post
51    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
52       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
53    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
54       keep global_ocean.90x40x15 (for AD testing) with former secondary test
55       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
56    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
57        add MITgcm_tutorials (= code + all the tutorials)
58    o ecco, option to compute cost for total ssh (mean+anom)
59    o consistent with addition of ptracer and ssh in pkg/profiles
60    o profiles: adding ptracer and ssh
61    o testreport: change multi-test output-file name
62      (from output.txt.{name} to output.{name}.txt)
63    o profiles: now ok for mutli-tiles case
64    o seaice: add 4 parameters for different advection schemes for area,
65      (effective) seaice thickness, enthalphy, and snow height. Their default
66      is the standard parameter SEAICEadvScheme
67    o calc_gw:
68     - add cosFacU in zonal viscous flux (harmonic.visc.).
69     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
70       of tutorial_plume_on_slope.
71    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
72    o calc_gw: true flux-form, account for horizontal grid spacing.
73      update rotating_tank results, but not plume_on_slope (affected at
74      truncation level, 11 digits).
75    
76    checkpoint58l_post
77    o calc_gw:
78     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
79     - remove side-drag for now (need to fix it); update plume_on_slope results.
80     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
81    o commit code to make SST/SSS weights spatially variable
82      (based on either variable in-situ or variable initial T/S weights)
83    o pkg/ecco:
84      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
85        now based on horizontally varying weights wthetaLev, wsaltLev
86      * cost_averagesflags now returns year indices in addition to day, month
87      * sflux balance is performed on annual basis
88        (sflxumm, sfluxmm2, bal_sfluxmm)
89      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
90        including separate counting and multipliers
91    o pkg/rbcs
92      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
93    
94    checkpoint58k_post
95    o testreport:
96     - always build in dir. "build" (if not there, mkdir build instead of building
97       & running in input)
98     - run in dir run (if it exists), in build otherwise.
99     - call prepare_run (if input/prepare_run exists)
100     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
101    o pkg/exf modifications to interpolation and rotation routines for more
102       reasonable treatment of North Pole singularity: for tracers North Pole
103       value is set to northernmost zonal-mean value, for zonal velocity it is
104       set to zero, and for meridional velocity it is set to northernmost value.
105    o pkg/exf/exf_check_range.F
106     - add tile index to diagnostics and move stop statement to the very
107       end of the routine.
108    o pkg/diagnostics: (diagnostics_main_init.F)
109      define title of isomorphic variables according to the current config.
110    o pkg/thsice with pkg/seaice dynamics:
111    - fix domain of computation (interior only, required for exf) and do exchanges
112    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
113    o towards a standard way of dealing with multi-threading in MONITOR
114      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
115    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
116       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
117    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
118    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
119    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
120       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
121    o tracer advection:
122     - clean-up and simplify calc_common_factors.F
123     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
124       advection subroutine (but still not used within DST advection S/R)
125    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
126    
127    checkpoint58j_post
128    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
129      from file (collects calls previously in FORWARD_STEP)
130    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
131    o adjoint store dir. adjusted accordingly
132    o genmake2
133      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
134    
135    checkpoint58i_post
136    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
137      on wind stress (SEAICEstressFactor defaults to 1.)
138    o Total number of Timers is finite (<=40): comment out 2 non-essential one
139      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
140    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
141      on CS-grid: no longer loosing mass.
142    o exf & curvilinear-grid: no longer modify longitude xC & xG.
143    o pkg/ggl90: fix sloppy output and fix a bug
144    o pkg/seaice: added SEAICEuseEVPpickup parameter
145      - Set to false in order to start EVP solver with
146        non-EVP pickup files when using SEAICEuseEVP
147      - fix sign error in diffusion in seaice_calc_rhs
148    
149    checkpoint58h_post
150    * Modifications for bottom topography control
151      o replace hFacC by _hFacC at various places
152      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
153      o add non-self-adjoint cg2d_nsa
154      o update autodiff support routines
155      o re-initialise hfac after ctrl_depth_ini
156      o works for 5x5 box, doesnt work for global_ocean.90x40x15
157    * Adding verification for 5x5 box (4-layer) bottom topography control
158    
159    checkpoint58g_post
160    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
161       used for mean seasonal cycle, mean diurnal cycle); add an example
162       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
163    o pkg/ggl90:
164      - add parameter (minimum surface kinetic energy)
165      - fix bug (avoiding division by zero)
166    o couple pkg/thsice to pkg/seaice:
167      - modify advection in seaice to accomodate new scalar fields to be advected
168      - only muliDimAdection scheme work with seaice/thsice
169      - mapping of thsice-variables to seaice-variables, back and forth
170      - does not break the verification experiments, but does not give the
171        desired results either
172    o pkg/seaice
173      - make (default) second order advection a bit less confusing?
174    
175    checkpoint58f_post
176    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
177      to pkg/seaice):
178      - new routines thsice_map_exf and thsice_get_exf provide the interface
179      - add an additional formal parameter to thsice_solve4temp
180    o pkg/exf:
181      - add new fields wspeed, snowprecip (to be able to couple to thsice)
182      - correct Stefan-Boltzmann constant
183      - new parameter for longwave surface emittance
184      - separate some stuff from exf_bulkformulae into new routines  
185        exf_radiation, exf_wind
186      - add new parameters and constants: longwave emissivity for ocean, ice
187        and snow, evaporation parameters over ice
188      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
189        either wind from stress or stress from wind
190    o pkg/thSIce:
191    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
192    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
193       and THSICE_CALC_THICKN
194    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
195    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
196      to make debugging easier.
197    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
198    o pkg/bulk_force:
199      - clean-up comments and parameters ;
200      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
201    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
202      generate new output for test-experiment: aim.5l_cs.thSI
203    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
204      testreport accordingly
205    
206    checkpoint58e_post
207    o SEAICE_CGRID adjoint done
208    o R_STAR adjoint implemented.
209      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
210      * need to sort out init. of h0facc, etc.
211    o Make pkg/profile fully independent of ecco,cost, etc. stuff
212      to be able to use it in pure forward.
213    
214    checkpoint58d_post
215    o upgrade simple test-experiment to tutorial example:
216     step.1: duplicate the experiment and (step.2) will remove the old copy.
217      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
218      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
219      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
220      tutorial_global_oce_biogeo    <- copy of dic_example
221      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
222      tutorial_plume_on_slope       <- copy of plume_on_slope
223      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
224      tutorial_global_oce_optim     <- empty for now (David ?)
225      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
226     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
227    o correct a sign problem in cost_scat.F
228    o obcs and ptracers: fix boundary conditions for advections schemes
229      with larger stencil
230    o thsice adjoint: start
231    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
232      completeness
233    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
234      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
235    o ptracers adjoint:
236      * avoid extensive recomputatations
237      * fix missing re-init. of gptr (missed by TAF)
238    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
239      me to turn off the excessive output to STDOUT that this package produces
240    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
241      and add those terms in Vector-Invariant formulation.
242    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
243      if the control period (xx_hfluxperiod etc) is 0
244    o in profiles pkg, clean routines and fix details
245    o in ecco pkg, reading ssh data:
246      fix problem in case the model does not start at iter0=0
247    o fix mnc-pickup/restart for ptracers
248    o new package prifiles:
249      code to compute profile-based cost by Gael Forget
250      (modifs in ecco, ctrl, autodiff)
251    o Benign bug fix in initialization (spotted by M. Mazloff) of
252      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
253    
254    checkpoint58c_post
255    o adjoint: finish NLFS adjoint and provide reference output in
256      verification/global_ocean.90x40x15/results_ad_nlfs
257    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
258      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
259      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
260      with SEAICE_CGRID defined.
261    o move calendarDumps from "data" to "data.cal" and clean-up the code
262      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
263    o add useEXF & useCAL flags (for now, set in hard-coded way)
264    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
265      (were missing in NH mode, and wrong in quasihydrostatic mode).
266      waiting for Chris updated version of calc_gw to add those CALLs.
267    o fix bug in quasihydrostatic S/R ;
268      add a test for this option: global_ocean.90x40x15.qshyd
269    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
270      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
271    o add on/off flag useOffLine for package OFFLINE
272    o seaice:
273      - modify advection so that it works also on the C-grid
274      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
275        problem in multi-tile runs with C-grid
276      - add flags for clipping ice velocities and/or masking solver forcing
277      - fix drag (ocean on ice) formulation and a bug that caused noise in the
278        C-grid solver
279      - added a few comments to seaice_diffusion.F
280      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
281        are now exclusive)
282      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
283        required re-ordering the code a little:
284       + make DAIRN global variable (defined in SEAICE)
285       + move computation of the viscosities eta and zeta into a new separate
286         routine (because I need to recompute them in seaice_ocean_stress.F)
287    
288    checkpoint58b_post
289    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
290      update output.txt of exp. aim.5l_cs.thSI
291    o various mnc cleanups and improvements:
292      + shrink lookup tables by factor of ~4
293      + better error reporting when running out of lookup space
294      + able to handle longer path/file names (up to 500 chars)
295    o adjoint:
296      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
297      - TBD: "hidden" mom_vecinv recomp. in dynamics
298    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
299     (allow to differentiate between forcing components using new integer flags:
300      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
301     and add new flag to put Dissipation tendency out of Adams-Bashforth.
302    o ecco
303      - enable trend removal from SSH anomaly obs.
304    o adjoint
305      - a fix for PmEpR when #undef EXACT_CONSERV
306      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
307      - try to fix "hidden" recomp. in forward_step for NLFS
308        (NLFS seems broken sometimes after I checked it in)
309    o seaice:
310     - add c-grid version of the dynamic solver:
311       + three new routines that are the c-grid substitute lsr, dynsolver
312         and ostres
313       + put a few fields that were local to dynsolver into global common
314         blocks, so that I can move the computation of stresses etc into
315         seaice_lsr (saves coding but may break the adjoint).
316     - replace more hardwired parameters by runtime parameters
317     - add ice masks that mask the rhs of the implicit solvers where there
318       is no ice (commented out in seaice_dynsolver, because i am not sure
319       if this works properly), eventually this should replace the clipping
320       of ice velocities in seaice_dynsolver to +/-40cm/s.
321    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
322      include it only where its needed
323    o move balancing of fluxes before the call of external_forcing_surf
324    o seaice:
325      - correct units of turning angles (now they are really in degrees)
326      - move computation of GWATX/Y out of main routine into dynsolver
327      - initialize GWATX/Y in seaice_init
328    o Apply mask on Fresh-Water flux (needed for SSH forcing).
329      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
330    o seaice: add runtime flags for turning angles (default to zero)
331    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
332      and trend from exf forcing and ctrl control adjustments
333    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
334      (since checkpoint57x_post)
335    o change the default rotation period to 86164.s = the Earth rotation
336    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
337      and based on a reference stratification. Tested within hs94.cs-32x32x5.
338    o seaice advection: add code for choosing between the default (2nd order
339      central differences) and multiDim advection schemes provided by
340      pkg/generic_advdiff
341    o seaice:
342      - removed all references to SEAICE_GRID.h fields from
343        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
344        (cubed-sphere configuration will change a little)
345      - grid computations in seaice_init are obsolete now.
346      - cleaned up code a little so that is easier to read (hopefully).
347      - added new (better?) discretizations of default advection and diffusion
348        (turn on with SEAICEuseFluxForm)
349      - replace 1 in 3d global fields by kSurface in growth.F
350      
351    checkpoint58a_post
352    o seaice:
353      - bug fix in advect.F
354    o shelfice:
355      - separate shelfice load anomaly from pload (breaks with time
356        dependent forcing), => introduce constant field shelficeLoadAnomaly.
357        Its default is 0., but it may be computed more cleverly from (unknown)
358        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
359        done offline. A good approximation of the pressure load anomaly is
360        necessary to avoid large initial adjustment processes underneath
361        deep-reaching shelfice.
362      - small fix in ISOMIP shelfice_thermodynamics
363      - add more sophisticated thermodynamics of Hellmer (1989), this is
364        now the default
365      - give a few constants more intuitive names
366    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
367      if bulk formulae are used in long integration (especially EmPmR). Turn
368      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
369      if balancePrintMean, the imbalance that is substracted is printed to
370      STDOUT.
371    o fix bug (typo) in obcs_apply_eta.F
372    o add a new package shelfice which enables us to model the circulation
373      underneath shelf-ice with draughts of hundreds of meters.
374     - works
375     - to do: + include improved thermodynamics
376              + check whether kSurfC (from model/inc/SURFACE.h) can be used
377                instead of new field kTopC
378              + can we use topoFile, Ro_surf and existing code in ini_depth.F
379                instead of new field R_shelfIce and new code in ini_depth.F
380                and ini_mask_etc.F?
381              + adjust vertical mixing schemes?
382    o seaice pkg:
383     - add a cpp-flag to include a simple formula for a salinity dependent
384       freezing point of sea water at the surface
385     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
386       meridional stresses are now different (and hopefully correct)
387    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
388       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
389       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
390    o pkg/diagnostics: add options and parameters for regional-statistics
391       diagnostics ; define regions by reading a region-mask from a file
392       (might add other options later)
393    o pkg/bulk_force:
394     - add option and parameters to use AIM surface-flux formulae.
395     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
396       others forcing fields (defined in PARM05, parameter file "data") are loaded
397       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
398     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
399     - use the right EXCH call for uwind,vwind (to work on CS-grid).
400     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
401       and parameters (note: calcWindStress replaces .NOT.readwindstress).
402     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
403    
404    checkpoint58
405    o add "--embed-source" option to genmake2 which, when the supporting
406      tools can be compiled (as determined by genmake2) will turn on the
407      embed_files package which then embeds the entire MITgcm source code
408      (*.[fFhc] + Makefile) used for the build within the executable
409      - requested by CNH but off by default
410      - adds a paltry <9MB to the mitgcmuv executable in most cases
411      - only writes the output when useEMBEDSRC in eedata is true
412    o clean up 3-dim. relaxation codes:
413      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
414      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
415      * Thanks to Tom Haine for testing!
416    
417    checkpoint57z_post
418    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
419      affects output (@ truncation level) of exp. plume_on_slope ; updated.
420    o fix the pickup behavior for obcs in combination with ptracers
421    o fix a bug in ptracers_external_fields_load
422    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
423      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
424    o transfered surface NH pressure to eta field (if exactConserv).
425    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
426         and update lab_sea output.txt file.
427    o completing 3-dim. relaxation code: additional term
428         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
429      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
430      * At compile time, in "EXF_OPTIONS.h" set
431          #define  ALLOW_CLIMTEMP_RELAXATION
432          #define  ALLOW_CLIMSALT_RELAXATION
433      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
434          tauThetaClimRelax3Dim = 15552000.0,
435          tauSaltClimRelax3Dim  = 15552000.0,
436      * 3 cases:
437          1) Use a constant-in-time 3-dim. field
438          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
439          3) Real-time relax. to time-evolving prescribed field
440    o Adding Laplacian-type smoothness constraint on
441      initial and boundary (forcing) controls (ic, bc)
442      * enable at compile-time via
443        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
444      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
445      * Absolute scale somewhat unclear so far
446      * no area weighting was included since no other cost term does so far
447    
448    checkpoint57y_post
449    First step for a NLFS adjoint
450    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
451    o new init. routines for calc_r_star, calc_surf_dr
452    o still need to deal with ini_masks_etc
453    o testreport seemed happy
454    checkpoint57y_pre
455    
456    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
457    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
458    o add new offset feature to offline pkg (plus minor cleanup)
459    o cfc fixes for final year of integration
460    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
461      be in GCHEM_OPTIONS).
462    
463    checkpoint57x_post
464    o fix testreport Pb in multiple test experiment.
465    o cleanup our namelist syntax in verification:
466      - make it more F95 standards compliant (some work still needed)
467      - allows the vast majority of our tests to work with gfortran
468    o Non-Hydrostatic:
469     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
470     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
471    o Allow to apply AB on T,S rather than on AB(gT,gS):
472     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
473     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
474       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
475     - need a "clever" read_pickup to restart from the other AB formulation
476    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
477    o remove some unused variables (reduces number of compiler warnings)
478    o adjoint
479      * Disable useVariableViscosity for adjoint for time being
480        (there are a number of extensive recomputations)
481      * Initialize certain variables needed for adjoint
482    
483    checkpoint57w_post
484    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
485                 fix the singleCpuIO RS version of MDSWRITEFIELD
486       and add a WARNING if using globalFiles=T with multi-processors.
487    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
488      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
489    o tracer advection scheme:
490      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
491       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
492       was not very convenient).
493      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
494       (further tests needed for the implicit DST & Flux-Limiter schemes).
495    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
496      and sRef for convenience, handy, when you want to initialize
497      ptracers in a large domain with a constant non-zero value. Also,
498      untangle ptracers_init.F a little.
499    
500    checkpoint57v_post
501    o change dome exp. to use variable viscosity in side-drag terms.
502    o remove all the files from the cfc_offline test since they are now
503      incorporated into tutorial_cfc_offline which has been producing
504      identical results for a few days of testing
505    o add new parameter: sideDragFactor to enable half-slip-side BC
506      and change side-drag S/R to use viscosity from mom_calc_visc
507      (can switch back by setting sideDragFactor=0.); affects results at
508      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
509       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
510    o vorticity & strain are now computed without masking, to account for
511      no-slip-side BC in variable viscosity calculation ; mask is applied
512      anyway later on, before computing advection/coriolis terms.
513    o modify exp4 to test new obcs support for reading from external files
514      and for passive tracers
515    o fix behavior of ptracers_monitor when monitor output is written to a
516      netcdf-file; still not independent of monitor.F (writes in the same
517      file).
518    o change default value of tRef (put a uniform, meaningful value for ocean
519      & atmos) and initialize sRef (was missing, as Martin mentioned).
520    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
521      to be proportional to enstrophy dissipation length.  Thus,
522       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
523      This is now consistent with Smagorinsky and with the manual.
524    
525    checkpoint57u_post
526    o OBCS and PTRACERS: add open boundary support for passive tracers
527      - either use homogenous (pseudo) v.Neumann conditions or prescribe
528        OB-values from file; this is not different from the way theta and salinity
529        are treated
530      - however, Orlanski-radiation conditions are not supported, and the model
531        will stop if you use pTracers and Orlanski at the same time.
532      - beefed up the rountine obcs_external_fields_load: now only those open
533        boundary values are overwritten with values from files for which there
534        are really files, otherwise the OB-fields remain untouched. This makes
535        it possible to use different OBs at different ends of the domain (as
536        with EXF)
537    o reduce number of exch calls in shap_filt (s2).
538    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
539      truncation level) 4/5 MLAdjust test results (11&12 digits match).
540    
541    checkpoint57t_post
542    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
543    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
544      same truncation, independent of the face number: affects affects several
545      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
546    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
547      note that biharmonic viscosity + no-slip was not tested in any experiment.
548    o fix bug in non-linear free-surf side-drag ; generate new output for
549      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
550    o make mnc honor the writeBinaryPrec flag for most kinds of output
551    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
552    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
553      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
554    o add brackets in multi-terms sum to get same truncation, independent of
555      the face number (manage to get exactly same value of gU,gV at the cs-edge)
556      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
557    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
558      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
559      a maximum grid-scale Reynolds number.  Also, changes all length calculations
560      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
561      Suggested values of viscosity parameters found in mom_calc_visc.
562      Many new viscosity diagnostics available.
563    
564    checkpoint57s_post
565    o Add clearing-house for viscosity calculations, mom_calc_visc and
566      correct numerous bugs in LeithD and Smagorinsky discretizations.  
567      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
568      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
569      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
570      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
571      The Strain-Tension form is now called with useStrainTensonVisc=.true.
572      ViscAhStrain and viscAhTension are now retired.
573    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
574    o In response to JMC's bug report, genmake2 now ignores any soft-links
575      that it finds in the *current* directory when searching for files.
576      Soft-links found in any other source directories will still work as
577      they did before.
578    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
579      a C routine to unlimit the stack size
580    o mnc-ify pkg/aim snapshot vars
581    o mnc-ify pkg/land as requested by Daniel
582    o various changes to mnc including:
583      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
584      - output can now be grouped so that all files within a group
585          change the ITER portion of their names in lock-step together
586      - can now read ("global") PER-FACE (in addition to PER-TILE) files
587          and works with both EXCH1 and EXCH2 (but needs more testing)
588      - writing works for all verification test cases w/ g77 on Linux
589    
590    checkpoint57r_post
591    o make MNC variable initialization happen earlier
592    o add diagnostics for (almost) each term of the momentum Eq.
593    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
594    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
595    o remove MINIMAL_TAVE_OUTPUT option ;
596      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
597    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
598      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
599    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
600    o add time-dependent SST, SSS control
601    o cost terms in ecco/ modularized (new cost_generic.F)
602    o cost_averages routines are modularized (new cost_averagesgeneric.F)
603    o new infrastructure for seaice model vs. obs misfits in seaice/
604      * driver from the_main_loop.F is seaice_cost_driver.F
605      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
606      * gradient check in Exp. 6a of natl_box_adjoint/
607    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
608      (see README file)
609    
610    checkpoint57q_post
611    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
612    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
613      - bug was reported by Jean-Michel and Ian Fenty
614    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
615      update exp. cpl_aim+ocn output.
616    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
617      Needed for high-res. runs with large global files
618      to be able to limit tapelev size
619    o Changed some tests for adjoint:
620      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
621      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
622      * global_ocean.90x40x15/ back to default 3-level checkpointing
623    o Modifications to enable scripted COMMON to MODULE conversion
624      * verification/OpenAD/code/ has necessary scripts and description;
625      * converts, compiles and runs successfully;
626    
627    checkpoint57p_post
628    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
629    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
630      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
631    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
632    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
633      (was already the case for dissipation with mom_vecinv,
634       and also the case for grad.PhiHyd when staggered-timeStep)
635      This will allow to put dissipation out-off the AB time-stepping.
636     Unfortunately, affects truncation error. Update output of exp. that "fails"
637      (cg2d matching number) and leave the others for later: front_relax(10),
638      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
639      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
640    
641    checkpoint57o_post
642    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
643      (2) its ready to be documented during the 20050801 DocFest
644    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
645      for ideal_2D_oce and lab_sea on linux_ia32_g77
646    o set to #undef CTRL_SET_OLD_MAXCVARS_30
647      in global1x1_tot/code_seaice_adj to access indices 32, 33
648      (worth another tag)
649    
650    checkpoint57n_post
651    o adding precip control xx_precip 32
652    o adding swflux control xx_swflux 33
653    o Replacing 10 forcing penalty cost routines by 1 generic.
654    o Implementing partitioning in time-mean and variable adjustment
655      for atmos. state.
656    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
657    o in natl_box_adjoint:
658      * updated exp 1 to 10
659        (but does not have time-mean vs. variable split results yet)
660    o updated global1x1/*_seaice_adj/
661      to incorporate latest changes
662    o enable useSingleCpuIO for mdsio vector routines
663      (applies in particular to tapelev I/O)
664    o removed inefficient K-loop in all active_file*control*.F
665    
666    checkpoint57m_post
667    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
668      and advect_cs (use EXCH-2 and standard cs-32 grid files).
669    o pkg/exch2: filling of face-corner halo regions is optional
670      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
671    
672    checkpoint57l_post
673     tag before updating tutorials (pre-release-2)
674    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
675       for output and interpolation of input fields onto model grid)
676    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
677       Affects results of exp. rotating_tank ; update output.txt.
678    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
679          and taking the square quantity and/or using a fraction-weight field.
680    o fix aim_diagnostics_init.F mate numbers.
681    o add mnc output capability to diagnostics/diagstat and update
682      our cvsignore files for the ACSII output generated
683    
684    checkpoint57k_post
685    o lab_sea now uses diagnostics package and provides a suite of
686      new EXF diagnostics output.
687    
688    checkpoint57j_post
689    o exf
690      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
691        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
692        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
693      * extended diagnostics output
694        - now includes all EXF variables
695        - hs, hl moved to common block
696        - separate S/R for diagnostics, called after ctrl vector is added
697        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
698        - EXFqnet contains true Qnet (i.e. includes qsw)
699      * updated verif. lab_sea, global_with_exf
700      * Rearranging hflux (exf_mapfields -> exf_getforcing)
701        to ensure that diagnostics sees a true EXFqnet
702    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
703    o diagnostics pkg: change pointers so that 1 diagnostic can be used
704      several times with different frequencies.
705    o mnc-ify the thsice package as requested by Daniel Enderton
706      - the monitor--MNC output needs work
707      - many attributes need to be added (most are currently blank)
708    o mnc-ify theaim_v23 package as requested by Daniel Enderton
709      - many attributes need to be added (most are currently blank)
710    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
711    o add Sadourny like discretization to the 4th.O vorticity advection scheme
712    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
713      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
714         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
715    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
716     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
717    
718    checkpoint57i_post
719    o Diagnostics package was changed: diagnostic allocation is now deactivated
720      by setting an empty file name in the namelist (used to be by setting 0 frequency)
721    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
722      add 1rst Order upwind vertical Shear.
723    o add a quick fix for A/B checkpointing in OFFLINE mode
724    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
725      end-run around the C/Fortran linking horror in eesup/src/timers.F
726    o added pkg/runclock: allows user to terminate run based on wall clock
727    o added non-hydrostatic scaling parameter: nh_am2
728    o pkg/my82: futile attempt to make results compiler-independent by adding
729      some "_d 0", etc. no effect.
730    o for mnc output, fill the 'T' coordinate var with myTime and create a
731      separate 'iter' variable for iteration count
732    o pkg/diagnostics:
733      add new capability: output of Global/Regional & per-level statistics ;
734      tested against monitor output (including land & thSIce) on various exp.
735    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
736    
737    checkpoint57h_done
738      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
739      data.diagnostics, data.gchem, data.ptracers) is done.
740    
741    o pkg/diagnostics: prepare for Global/Regional statistics.
742      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
743    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
744      and rename it: DIFFERENT_MULTIPLE
745    
746    checkpoint57h_post
747    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
748    o pkg/diagnostics: change output frequency, now in seconds (instead
749      of Nb of iterations). This requires to change data.diagnostics.
750    checkpoint57h_pre
751    
752    o in mnc, let the user create the output dir if both mnc_outdir_date
753      and mnc_outdir_num are false
754    o add fflags() to pkg/diagnostics which allows one to specify, on a
755      per-file basis, the file precision [default behavior is unchanged]
756    o added diagnostics to pkg/kpp, including computation of mixed layer
757      depth based on a temperature/density criterion
758    o updated verification/natl_box to test the new pkg/kpp diagnostics
759    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
760    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
761    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
762      not mnc -- this mistake was found by JMC and is now corrected
763    
764    checkpoint57g_post
765    o add Adams-Bashforth 3rd Order time stepping:
766      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
767      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
768    checkpoint57g_pre
769    
770    o make lambda[Theta,Salt]ClimRelax spatially varying
771      (default remains spatially uniform constant based on tau)
772    o added new control variables
773      * init. uVel, vVel, etanN
774      * lambda[Theta,Salt]ClimRelax
775    o separate masks used for ctrl_pack/unpack 'from write_grid' output
776      (suggested by G. Forget)
777    
778    checkpoint57f_post
779    o add parameter "baseTime" = model base time = time at iteration zero
780      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
781      account for baseTime shift
782    o move Coriolis arrays from PARAMS.h to GRID.h
783    checkpoint57f_pre
784    
785    o mnc-ifying the seaice package
786    o introduced an alternative length scale calculation for use in the limiting
787      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
788    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
789    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
790      as well as grad(vort3).  Made it compatible with both approximate form
791      for the cubed sphere and full form of these gradients.  Added flag
792      useFullLeith to select between approximate and full form.  
793    o add "d0" in getcon.F to reduce differences between compilers/platforms
794      update output.txt of exp. fizhi-gridalt-hs
795    o change port_rand funtion to allow to set the seed.
796    o fix obscure MNC bug involving conversion between reals and integers
797      - it caused no problems with certain (eg. gcc, ifc) compilers but the
798        new version is now more standards-compliant
799    o adjoint-related modifications
800      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
801      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
802      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
803    
804    checkpoint57e_post
805    o Adding eddy stress controls a la Ferreira et al.
806    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
807    
808    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
809      update output.txt of exp. fizhi-gridalt-hs
810    o add more "Z" dimensions and associated coordinate vars to MNC
811    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
812    o parameter calendarDumps: when set, approximate months (30-31 days) and years
813      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
814      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
815      months and years.  Requires pkg/cal.
816    o diagnostics: add pickup functionality
817      - off by default for backwards compatibility
818      - current version only uses MDSIO -- MNC will be added
819    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
820    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
821    
822    checkpoint57d_post
823    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
824    o modify verification/ideal_2D_oce so that it tests the creation of mnc
825      output from the diagnostics package
826    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
827    o make genmake2 more portable by using ".$FS" instead of ".f" for more
828      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
829    o add coordinate variables to the MNC output from the diagnostics package
830    o change MNC-flags default value: true when useMNC=TRUE
831    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
832      the ability (off by default) to read the grid information using MNC
833    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
834    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
835    o do snap-shot diagnostics at the middle of the time-interval (instead of
836      at the end).
837    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
838      new test for AIM with thSIce + slab-ocean
839    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
840    o move state variable diagnostics to the beginning of the time step ;
841      (note: still needs some work specially for snap-shot diagnostics)
842      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
843    
844    checkpoint57c_post
845    o Change testing option (-ieee) to get closer agreement between g77 & ifort
846    o generate new output.txt files on faulks with g77 & the new -ieee option
847    checkpoint57c_pre
848    
849    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
850      update output.txt of exp. global_ocean.90x40x15
851    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
852      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
853    o add saltFlux(+File) forcing capability with periodicExternalForcing
854    o allow to use pkg diagnostics for GM-Redi & ThSIce output
855    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
856    o improvements for the MNC output from DIAGNOSTICS:
857      - correct handling of the unlimitied dimension
858      - all dims now have associated coordinate variables
859      - variables located at U, V, and Corner ("Z") points are now written
860        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
861        *all* data points are output
862    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
863    o added pkg/seaice/seaice_monitor.F
864    o mdsio_readfield.F can now read files visible only to master MPI process.
865    o pkg/seaice: some test code for ice-modified ocean stress
866    o exf_getffields interpolation defaults to bilinear for all scalar forcing
867      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
868      spurious negative numbers for precipitation and humidity.  Will cause
869      some small numerical differences for integrations using pkg/exf/exf_interp.F.
870    o pkg/ctrl/
871      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
872        May be enabled via doPackDiag
873      *  introduce z-scaling of
874         + gradient (doZscalePack) and
875         + control (doZscaleUnpack)
876    o pkg/mdsio/
877      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
878      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
879    
880    checkpoint57b_post
881    o simplify options in diagnostics_fill arguments (remove weird combinations)
882    o fix MNC coordinate variables so that they now contain per-face index
883      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
884      general, EXCH2 grids are only aligned to a "local" coordinate system
885    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
886    o Implement instantaneous output within pkg diagnostics:
887      setting a negative frequency in data.diagnostics produces
888     "snap-shot" output (as opposed to time-average if freq > 0)
889    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
890      NOTE: change ptracer diagnostics name: use 2 characters to work with
891            more than 9 tracers. Add also diagnostics of advect & diffus flux.
892    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
893      becomes the coordinate variable for the 'T' dimension
894    o add CF-style coordinate variables to MNC
895      - just a first cut:  numbers are meaningless on the cubesphere and
896        missing along the T axis but otherwise it works!
897    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
898    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
899    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
900      this is based directly on what the model compute, so that the content of
901      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
902    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
903    o clean up build options files for SunOS, in particular
904      - remove -traditional from xmakedepend
905      - change -xarch=v9 to -xarch=native for f77
906      - restore use of make (not gmake)
907      - add CC=gcc if using g77
908    o changes per discussion of AM, JMC, & EH3 today:
909      - move redundant "grid" variables out of "state" -- in preparation of
910        creating proper CF-style coordinate variables and in recognition
911        that any/all grid variables can be easily copied (eg. w/NCO) from
912        the grid files into any of the other NetCDF files
913      - *always* output grid variables with MDSIO (this will eventually be
914        changed)
915      - output MNC grid file if useMNC is true
916    o every instance of _END_MASTER() has been found and replaced with
917      _END_MASTER( myThid ) in order to satisfy certain picky Sun
918      preprocessors
919    o re-arrange diagnostics pkg initialisation:
920     - allow each package to extend the available diagnostics list
921     - add some checking and fix small problems (multi-threaded, ...)
922     - new S/R diagnostics_fill (replace fill_diagnostics):
923       look through the short list of active diag. (instead of the long list)
924       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
925    
926    checkpoint57a_post
927    o this set of changes restores TAMC compatibility
928      tested for global_ocean.90x40x15 adjoint on trough
929      (what a pain)
930    
931    checkpoint57a_pre
932    o some modifs in tools/build_options for sunos
933    o call ctrl_pack for ctrl at end for optimcycle=0
934    
935    checkpoint57
936    o add horizontal bi-harmonic viscosity for vertical velocity
937      - new parameter viscA4W (defaults to viscA4)
938      - affects only non-hydrostatic code
939      - to be done: no-slip lateral boundary conditions
940    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
941    o implement Implicit Vertical advection for pTracers
942    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
943      (implemented also for implicit vertical diffusion & advection)
944    o OBCS: extend application of tracer open boundary conditions
945      to a strip beyond the boundary of width Olx/Oly
946    o add call monitor to TAF set of required calls (flow directives)
947      and include in natl_box_adjoint
948    o untangle a few ifdefs related to cost, ctrl, autodiff
949      untangel a few ALLOW_ECCO_OPTIMIZATION
950    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
951      (theta2, salt2 in ecco_cost_weights)
952    
953    checkpoint56c_post
954    o OBCS as control variables
955      - update ctrl_ad_diff.list, obcs_ad_diff.list
956      - remove balance of obcs controls from default
957      - fix index bug nobcs in ctrl_init
958      - fix dummy fields filen in ctrl_pack
959      - add dummy weights for obcs
960    o lsopt: comment out fort.94 output
961    o optim:
962      - remove unnecessary header files
963      - adjusted namelists
964      - add xerbla.F to Makefile
965    o exf:
966      - multiple modifications of exf_check_range
967      - unit change in exf_init_runoff from [m/year] to [m/s]
968    o mdsio:
969      - i/o-vector change debugLevel from debLevA to debLevB
970    
971    checkpoint56b_post
972    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
973      is called from DO_THE_MODEL_IO
974      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
975      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
976      - clean up PTRACERS_WRITE_TIMEAVE a little
977    o add another verification experiment that tests both the cfc-pkg and
978      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
979      reactive tendencies treated inline with regular timestepping
980    o testreport previously did a lousy job of comparing small numbers, so
981      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
982      implemented in the little c-progam tmp_cmpnum.c which is embedded in
983      testreport.
984    o ptracers_monitor: bug fix for MPI
985    
986    checkpoint56a_post
987    o GCHEM: finish reorganizating the package
988      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
989        (introduces another 3D-array for each passive tracer, but only if
990        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
991        gchemTendency is not needed because the timestep is done separately)
992      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
993      - GCHEM is now---more or less cleanly---separate from PTRACERS
994      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
995        so clear to me how that should be done in a general way.
996    o CFC: improve formatting of output in CFC_ATMOS
997    o PTRACERS:
998      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
999        that ALL experiments with ptracers enable can be checked. This makes
1000        GCHEM_MONITOR obsolete.
1001      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1002        monitorFreq
1003      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1004    o add PTRACERS (PTR0[1-5]) to testreport output
1005    o exf_check_range:
1006      * default changed to .TRUE.
1007      * will check values for niter0 if debLevA, every timestep if debLevB
1008      * STOP in exf_check_range if 'out of range'
1009      * range chosen generous to allow for potential extema
1010      TBD: a version with stricter range
1011           permitted range would be runtime parameters
1012    o GMredi:
1013      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1014      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
1015      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
1016    o GCHEM:
1017      - move call to GCHEM_FORCING_SEP, so that it is now called before
1018        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
1019      - introduced a useGCHEM runtime flag and applied it everywhere.
1020      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1021        this flag is now only visible within GCHEM-pkg routines.
1022      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1023        be replaced by a 3D array that is computed before thermodynamics; for
1024        this, the tracer ID iTracer had to be included into the parameter list
1025        of ptracers_forcing
1026      - set up forward_step to call gchem_forcing, that will replace
1027        gchem_forcing_int in ptracers_forcing
1028      - cleaning up
1029    o small cleaning of exch2: remove files that are also in eesupp/src
1030    
1031    checkpoint56
1032    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
1033    o mnc: cleanup "full" files--fixes out-of-memory problem
1034    o ECCO-GODAE
1035      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
1036      * fully merged and updated from SIO code
1037        windstress sign change affects
1038        - exf_inscal_[u/v]stress
1039        - sign of xx_tau[u/v] adjustments
1040        - signs in cost_scat
1041      * ctrl_get_gen: avoid update of tau[u/v] for first few days
1042      * natl_box_adjoint updated and compressed
1043      * 2-level checkpoint switch added
1044        (tested in EXP. 1 of natl_box_adjoint)
1045      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
1046    o SVD
1047      * first complete, non-hacked version for SVD calculations
1048      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
1049        performed via direct access files admtlm_vector.it????
1050        (via ctrl_[un]pack)
1051      * optimcycle is used for ARPACK iteration counter
1052        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
1053      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
1054        and add linear transforms where necessary
1055      * controls are initial/final SST, SSS (can be extended; need to check
1056        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
1057    o mdsio: filename info to both stderr, stdout
1058    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
1059      from sign change
1060    
1061    checkpoint55j_post
1062    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
1063      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1064    o add consistent build directories and .cvsignore files to verification
1065    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
1066    o make all subroutines 30 or less characters in length for certain older
1067      compilers to work (a thorough search only turns up two routines in
1068      pkg/ptracers)
1069    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
1070      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1071    
1072    checkpoint55i_post
1073    o change arrays for total vertical diffusivity (2.D if explicit,
1074      3.D if implicit) ; each ptracer uses its own background value.
1075    o added mnc/NetCDF output capability to ocn_compon_interf
1076      - added bits to verification/cpl_aim+ocn so that it can run on
1077        ITRDA and other clusters without the mpirun "-wd" option
1078    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
1079      configuration
1080    o give MNC the ability to create additional files rather than
1081      exceeding a specified file size limit "MNC_MAX_FILESIZE"
1082      - the default is just less than 2GB which is a practical limit
1083        on many systems
1084    o Compute the non-local term using either KPP vertical diffusivity (=default)
1085       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
1086    
1087    checkpoint55h_post
1088    o add verification test "vermix"
1089    o remove all the *_ioinc flags and replace with the single global
1090      outputTypesInclusive flag
1091    o allow to set a vertical profile of vertical diffusivity for T & S
1092    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
1093    o useMNC moved from data.mnc to data.pkg
1094    
1095    checkpoint55g_post
1096    o Renaming carbon AD experiments to comply with testreport conventions
1097    o Updating adjoint of Held-Suarez hs94.1x64x5
1098    o Fixing directives for non-ECCO forward_step, after ECCO directives
1099      have been fixed to avoid recomp. of do_oceanic_phys
1100      Works well for global_ocean.90x40x15,
1101      but recomp. issue remains for carbon
1102    o Updating adjoint output for natl_box_adjoint after
1103      pkg/ecco has been modified (see taga c55d_post)
1104    
1105    checkpoint55f_post
1106    o rename to timeave_init_fixed
1107    
1108    checkpoint55e_post
1109    o some delicate re-shuffle of store directives to avoid one
1110      extra call of do_oceanic_physics
1111      affects ecco_the_main_loop.F, do_oceanic_physics.F
1112      checkpoint_lev1_directives.h
1113    o NB: this may break global_ocean adjoint temporarily,
1114      but it is clear how to fix it. Will do later, need this now.
1115    
1116    checkpoint55d_post
1117    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1118    o ecco_cost_weights is modified to 1x1 runs
1119    o modifs to allow observations to be read in as
1120      single file or yearly files
1121    o enable to read exf forcing fields as either
1122      single file or yearly files (flag useExfYearlyFields)
1123    checkpoint55d_pre
1124    
1125    o switch between 2-level and 3-level checkpointing
1126    o add ability of MNC to write local and "partial" (eg. 2D slices where
1127      the full 3D field is never actually stored) arrays to NetCDF files
1128      with the correct (that is, the complete multi-dimensional) set of
1129      array indicies
1130      - used in mom_vecinv() to write the diagFreq output
1131      - tested (demonstrated) in verification/aim.5l_cs
1132    o further mnc-ification
1133      - add verification/lab_sea to the list with mnc setups
1134      - fix undefined mnc v-names in cd_code
1135      - add kpp to mnc output (both snapshot and timeave)
1136    o non-hydrostatic code
1137      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1138        in calc_gw.F
1139      - defaults to viscAh
1140      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1141        friction or Leith) in non-hydrostatic mode, as long as there is
1142        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1143    o pkg/cost
1144      extend simple cost functions to treat time mean quantities
1145      (T,U,V) via cost_accumulate_state from cost_tile
1146    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1147        be 2 times larger than the minimum size the advection scheme requires.
1148        now get a perfect conservation of salt in advect_cs test-exp (updated)
1149    o GGL90 (Gaspar's TKE mixed layer)
1150      - add horizontal diffusion of TKE, requires exchanges in
1151        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1152        default. In OPA there is no horizontal diffusion of TKE but the
1153        mixing coefficients are computed from a horizontal average of TKE of
1154        6 points or so. I think that diffusion has a little more physical
1155        justification.
1156      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1157        was in vain)
1158      - mask tke-variable in ggl90_init
1159    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1160    o fix biharmonic diffusion on CS-grid.
1161    o more obcs stuff
1162      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1163        for reading boundary values. This routine is called from
1164        obcs_prescribe_read
1165      - updated obcs_check
1166      - changed sponge layer relaxation parameter units for days to seconds
1167      - turned off sponge layer by default
1168      - changed argument list of OBCS_CALC to myTime+deltaTclock
1169      - fixed about 35 bugs in obcs_external_fields_load
1170    
1171    checkpoint55c_post
1172    o obcs stuff
1173      - new runtime flags useOBCSprescribe, useOBCSbalance
1174      - re-arranged obcs_calc
1175      - moved exf_getobcs to obcs_prescibe_read
1176        obcs_prescibe_read is called after ORLANSKI stuff
1177        and independent of it (executable can contain all).
1178      - updated obcs_check
1179      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1180        These may be necessary only if tangential velocities are
1181        prescribed at OB, not sure, needs testing.
1182    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1183      which simplifies the calls and passes the ifc check-bounds test
1184    
1185    checkpoint55b_post
1186    o add a 2D scalar, Z location, exchange_2 routine.
1187    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1188      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1189      affects advect_cs results (for the wrong reason): update output.txt
1190    o use a more standard discretization for biharmonic viscosity ;
1191     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1192      affects results of dome set-up: update output.txt
1193    o fix gad_advection.F (CubedSphere part), back to version 1.23
1194    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1195    
1196    checkpoint55a_post
1197    o merged code to
1198      * prescribe/read time-dependent open boundaries
1199        (works in conjunction with exf, cal)
1200      * sponge layer code for open boundaries
1201      * each boundary N/S/E/W now has its own CPP option
1202        (healthy for the adjoint)
1203    
1204    checkpoint55
1205    o up-to-date adjoint of previous breaks
1206      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1207      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1208      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1209      - carbon: * remove tr1-related adjoint verification
1210                * add ptracer as control variable
1211    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1212      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1213    
1214    checkpoint54f_post
1215    o in verification/carbin/ remove experiment related to
1216      ALLOW_PASSIVE_TRACER (array tr1 etc)
1217      code_ad/ input_ad/ results_ad
1218    
1219    o add two new packages
1220      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1221        + subject to optimization (memory)
1222      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1223        + subject to reordering (many GOTOs in the original code)
1224        + so far opps is called for every (i,j) point, and then operates in
1225          the vertical; one may want to reorder the scheme in order operate in
1226          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1227          fields)
1228    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1229      - all verification tests compile and run with linux_ia32_g77
1230      - defaults are compatible with current input files--nothing
1231        should change if you were not previously using MNC
1232      - MNC output has been added in numerous places (eg. timeave)
1233        but there are still a few writes not yet do-able with MNC
1234        (this is in progress)
1235      - flags now allow for either/or/both use of MDSIO and MNC and
1236        documentation will soon follow
1237      - numerous small formatting cleanups for ProTeX
1238    o add version info (via BUILD_INFO.h) to MNC and stdout
1239    
1240    checkpoint54e_post
1241    o add two new packages
1242      - pp81 (Packanowski and Philander, 1981), Richardson number and
1243        stratification dependent mixing
1244      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1245      - these scheme operate in a similar manner as KPP (without ghat, of
1246        course), however there is only one diffusivity that is used for both
1247        temperature and salinity (and passive tracers)ç
1248    o add offline package
1249    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1250      provided by Stephanie Dutkiewicz
1251    o genmake2: add ability to search for C compilers and cleanup test output
1252      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1253    
1254    checkpoint54d_post
1255    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1256    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1257      leading to additional shift by 5 days each year of integration
1258       (i.e. leading to considerable offset over the years)
1259    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1260    o start with no AB and no initial filtering (staggerTimeStep):
1261      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1262    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1263      (external loading & cpl import/export stay in forward_step.F)
1264    o update coupling interface to work with new staggerTimeStep
1265    o change MDSIO ptracers_pickup.
1266    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1267    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1268    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1269    
1270    checkpoint54c_post
1271    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1272      this affects (truncation error) output.txt of test-exp:
1273       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1274    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1275    o change Qnet to always be the net heat flux, (+upward).
1276      affects (truncation error) output of natl_box exp.: updated
1277    o define the max number of passive tracers in PTRACERS_SIZE.h
1278    o start to test mnc routinely in exp0
1279    o add sea-ice loading (sIceLoad) as a new forcing field.
1280    
1281    checkpoint54b_post
1282    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1283       impressive on Altix and Opteron systems)
1284    o diagnostics can now write NetCDF files through the mnc package
1285    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1286    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1287    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1288      affects (truncation error) output of lab_sea & natl_box exp.: updated
1289    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1290    
1291    checkpoint54a_post
1292    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1293    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1294    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1295    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1296      + internal_wave (shift in writing cg2d_ini_res)
1297    checkpoint54a_pre
1298    
1299    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1300      - modified verification/lab_sea and natl_box_adjoint accordingly
1301    
1302    checkpoint54
1303    checkpoint53g_post
1304    o prepare splitting of thermodynamics: store convect.counter in common block
1305    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1306      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1307    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1308    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1309    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1310    o restore adjointability
1311    
1312    checkpoint53f_post
1313    o modifications that affect AIM experiment results (update output.txt):
1314      - no advection of S at top interface Nr (pkg/generic_advdiff)
1315      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1316    o AIM pkg:
1317      - include stability function into surf.Flux derivative relative to Tsurf
1318      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1319    
1320    checkpoint53e_post
1321    o merged cylindrical coord configuration
1322    o added rotating_tank experiment
1323    checkpoint53e_pre
1324    
1325    checkpoint53d_post
1326    o faulks upgraded: re-generate output.txt that have changed:
1327       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1328    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1329    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1330    o added Sadourny discretization of Coriolis
1331      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1332      - re-enabled use of omega3 (useAbsVorticity)
1333    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1334      vector-invariant equations
1335      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1336    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1337      hopefully without new bugs
1338      - still to do: biharmonic friction for non-hydrostatic w
1339    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1340    o regenerated output for global_ocean_ebm (using -ieee)
1341    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1342      of mom_common/
1343      - simple re-arrangement of instructions within computing loop
1344    checkpoint53d_pre
1345    
1346    checkpoint53c_post
1347    o new version of coupler for AIM+thSIce and Ocean models
1348     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1349     - land: change Evaporation of snow
1350     - aim with thSIce: fix bug in snow-precip.
1351    o changes to calc_gw.F
1352     - bug fix for w^2 term near the bottom boundary
1353     - (hopefully) improve the lateral slip boundary condtions for use with
1354        partial/looped cells
1355      - because the bug fix changes two verification experiments anyway (exp5
1356        and plume on slope), change the lateral boundary condition from half slip
1357        to the value of no_slip_sides
1358    o ebm package wasnt quite up to the parallel task. Fixed that.
1359    o Adjoint of EBM package + verification
1360      * TLM OK
1361      * ADM not sufficient accuracy yet (needs further testing)
1362    
1363    checkpoint53b_post
1364    o Commiting new energy balance model to repository
1365      * package is pkg/ebm
1366      * verif. is verification/global_ocean_ebm
1367      * references are in ebm_driver.F
1368    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1369    C        Global thermohaline circulation. Part I:
1370    C        Sensitivity to atmospheric moisture transport.
1371    C        J. Climate 12(1), 71-82
1372    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1373    C        Global thermohaline circulation. Part II:
1374    C        Sensitivity with interactive transport.
1375    C        J. Climate 12(1), 83-91
1376    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1377    C        Destabilization of the thermohaline circulation
1378    C        by atmospheric eddy transports.
1379    C        J. Climate 7(12), 1870-1882
1380    o Will need long integration testing.
1381    checkpoint53b_pre
1382    
1383    o created pkg/mom_common in preparation for variable viscosity code
1384    o renamed and split ini_mnc_io
1385    o pkg/land: only liquid water can diffuse or run-off
1386    o AIM using land: soil wetness availability account for snow
1387    o added printMapIncludesZeros to EEPARMS namelist
1388    
1389    checkpoint53a_post
1390    o restore TAMC compatiility for exf_constants.h
1391      (no usage of _d in .h)
1392    o Additional storing in KPP in an attempt to fix
1393      TAMC problem with adjoint of KPP code.
1394      (no success...)
1395      Identical code works fine with TAF.
1396    o Fixed verification/natl_box_adjoint experiments.
1397      Initial conditions for Experiments 4 and 5 are now
1398      set to "SEAICE_initialHEFF=0", which is more reasonable,
1399      and hence gives results closer to that of Experiment 2.
1400      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1401    
1402    checkpoint53
1403    o stable checkpoint with up to date adjoint
1404      TLM tests only run for 1st grdchk at the moment. Its unclear if
1405      this is a code problem or a problem with resetting code for g_
1406      variables that is being autogenerated wrong.
1407      Otherwise:
1408       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1409       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1410         are both still in chaos following their security messes.
1411    
1412    checkpoint52n_post
1413    o various build (mostly genmake2) changes including:
1414      - ability to build/run more easily within Cygwin and MacOS X
1415      - more complicated Makefiles with a stronger dependence on Gnu Make
1416    o pkg/seaice modifications
1417      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1418        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1419        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1420      - changed proxy for geostrophic velocity and updated
1421        verification/lab_sea/results/* accordingly
1422      - removed ADI dynamic solver from pkg/seaice
1423      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1424        they caused a segmentation fault under certain circumstances
1425      - removed unused field WATR
1426    o bug fix in exf-package:
1427      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1428         now reflect that.
1429    o small fixes in the cal-package:
1430      - set reference date to first of January for the 'model'-calendar
1431      - failing of cal_CheckDate in cal_FullDate now actually results in a
1432        warning
1433    o small modifications in exf-package to increase flexibility:
1434      - change climtempfreeze from a constant to a runtime parameter that
1435        is specified in data.exf_clim (default = -1.9)
1436      - introduce runtime parameter windstressmax (default = 2.0) that is
1437        specified in data.exf
1438    o fix in pkg/thsice:
1439      - update Evap (Tsf changes) to be consistent with Latent heat flux
1440      - maintain snow precipitation unchanged (even if Tsf >=0).
1441     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1442    
1443    checkpoint52m_post
1444    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1445      this does not change any of the results, because myIter=0 in swfrac always
1446      lead to jwtype=2 (the default anyway), but the call makes little sense
1447      as a default
1448    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1449    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1450      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1451    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1452    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1453    o extending useSingleCpuIO option to work with new exch2 I/O format
1454      - old-style, missing-tile I/O is still accessible by defining CPP
1455        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1456    o monitor package can write to NetCDF files and/or STDOUT
1457    o fix re-definition bug in MNC_GRID_INIT_ALL()
1458    o doc/api_reference added
1459      - a framework for building an API Reference Manual using all
1460        the "protex" comments embedded in the code
1461      - see pkg/generic_advdiff, pkg/mnc for examples

1517      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1518      TAF places a faulty re-call of initialise_varia
1519      after cost_final call which should not be there!
1520    checkpoint52j_pre
1521
