5      ==============================      ==============================
6    
7    o profiles: fix for multithreaded case
8    
9    o diagnostics: rename few diags:
10      s/'PRESSURE'/'RCENTER '/g
11      s/'TICE    '/'oceFreez'/g
12      s/'TAUX    '/'oceTAUX '/g
13      s/'TAUY    '/'oceTAUY '/g
14      s/'SWFLUX  '/'oceQsw  '/g
15      s/DIFx/DFxE/g
16      s/DIFy/DFyE/g
17      and add few ocean-forcing diagnostics:
18      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
19    o modifications to pkg/seaice/growth.F and budget.F, which change results of
20      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
21      as actual snow thickness.  It now refers everywhere to effective snow
22      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
23    
24    checkpoint58r_post
25    o modifications to pkg/seaice/growth.F, which change results of
26      lab_sea experiment: fixes pertain to melting snow over open water, to
27      masking EVAP under sea ice, and to using the correct AREA variable for
28      computations of EVAP, PRECIP, HSNOW, and GHEFF
29    o add ability to read bathy, salt, and theta using MNC (off by def)
30    o add flooding algorithm and advection of HSNOW for pkg/seaice;
31      both are turned off by default and do no change any results
32    o seaice advection with pkg/thsice: a step toward the use of non-linear
33      advection scheme, but #ifdef or commented out for now (requires more EXCH).
34    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
35      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
36      in natl_box (affects results @ truncation level: update output.txt)
37    o multi-threading and IO:
38      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
39      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
40        (needed to work with SingleCpuIO): tested in all verif. exp.
41    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
42      affects the results (but none of the verification test uses this scheme).
43    o Adding some pkg/diagnostics capability to pkg/seaice
44      (will certainly be subject to changes)
45    o ctrl: adding new control variables:
46      lwflux, lwdown, evap, snowprecip, apressure, runoff
47    
48    checkpoint58q_post
49    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
50      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
51      high_res_cube configuration by 4% on Columbia.
52    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
53      add (in global_with_exf/code) a version of EXF_INTERP_READ without
54      dynamical allocation (seems to work in multi-threaded).
55    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
56      single CPU io) so that TAF does not have to see EESUPPORT.h
57    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
58    
59    checkpoint58p_post
60    o obcs: stop if obcs is used with useCDscheme = .true.
61    o shelfice:
62     - fix a sign error so that no slip at shelfice interface works
63     - remove stop for combination non-hydrostatic code and shelfice. That does
64       not mean, that the results are correct, but at least they are numerically
65       stable
66    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
67    o added adjoint exch routined for all exch*3d* routines
68      and updated flow directives
69    
70    checkpoint58o_post
71    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
72      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
73    o change controling S/R for writing pickup file (new S/R do_write_pickup)
74      and clean-up reading/writing of pickup files.
75    o fix local version of read/write pickup (NH part) in rotating_tank/code
76    o simplify EXCH interface:
77     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
78     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
79    o added the regrid package
80    o shelfice:
81     - add a simple boundary layer scheme to reduce noise
82     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
83    
84    checkpoint58n_post
85    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
86       local variable (not in common block).
87    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
88      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
89      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
90        to work with SingleCpuIO.
91    o add "_d 0" to real constant of pkg/cfc subroutines ;
92       update exp. cfc_exemple & tutorial_cfc_offline output files.
93    o multi-threading and IO:
94      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
95        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
96      - barrier before and after reading.
97      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
98      - avoid using MDS_WRITELOCAL for LAND pkg output.
99      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
100        common-block variables ; Allows multi-threading with master-thread IO.
101    o change default MAX_NO_THREADS from 32 to 4 ;
102      and stop cleanly when MAX_NO_THREADS is too small.
103    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
104    
105    checkpoint58m_post
106    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
107       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
108    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
109       keep global_ocean.90x40x15 (for AD testing) with former secondary test
110       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
111    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
112        add MITgcm_tutorials (= code + all the tutorials)
113    o ecco, option to compute cost for total ssh (mean+anom)
114    o consistent with addition of ptracer and ssh in pkg/profiles
115    o profiles: adding ptracer and ssh
116    o testreport: change multi-test output-file name
117      (from output.txt.{name} to output.{name}.txt)
118    o profiles: now ok for mutli-tiles case
119    o seaice: add 4 parameters for different advection schemes for area,
120      (effective) seaice thickness, enthalphy, and snow height. Their default
121      is the standard parameter SEAICEadvScheme
122    o calc_gw:
123     - add cosFacU in zonal viscous flux (harmonic.visc.).
124     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
125       of tutorial_plume_on_slope.
126    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
127    o calc_gw: true flux-form, account for horizontal grid spacing.
128      update rotating_tank results, but not plume_on_slope (affected at
129      truncation level, 11 digits).
130    
131    checkpoint58l_post
132    o calc_gw:
133     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
134     - remove side-drag for now (need to fix it); update plume_on_slope results.
135     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
136    o commit code to make SST/SSS weights spatially variable
137      (based on either variable in-situ or variable initial T/S weights)
138    o pkg/ecco:
139      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
140        now based on horizontally varying weights wthetaLev, wsaltLev
141      * cost_averagesflags now returns year indices in addition to day, month
142      * sflux balance is performed on annual basis
143        (sflxumm, sfluxmm2, bal_sfluxmm)
144      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
145        including separate counting and multipliers
146    o pkg/rbcs
147      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
148    
149    checkpoint58k_post
150    o testreport:
151     - always build in dir. "build" (if not there, mkdir build instead of building
152       & running in input)
153     - run in dir run (if it exists), in build otherwise.
154     - call prepare_run (if input/prepare_run exists)
155     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
156    o pkg/exf modifications to interpolation and rotation routines for more
157       reasonable treatment of North Pole singularity: for tracers North Pole
158       value is set to northernmost zonal-mean value, for zonal velocity it is
159       set to zero, and for meridional velocity it is set to northernmost value.
160    o pkg/exf/exf_check_range.F
161     - add tile index to diagnostics and move stop statement to the very
162       end of the routine.
163    o pkg/diagnostics: (diagnostics_main_init.F)
164      define title of isomorphic variables according to the current config.
165    o pkg/thsice with pkg/seaice dynamics:
166    - fix domain of computation (interior only, required for exf) and do exchanges
167    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
168    o towards a standard way of dealing with multi-threading in MONITOR
169      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
170    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
171       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
172    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
173    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
174    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
175       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
176    o tracer advection:
177     - clean-up and simplify calc_common_factors.F
178     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
179       advection subroutine (but still not used within DST advection S/R)
180    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
181    
182    checkpoint58j_post
183    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
184      from file (collects calls previously in FORWARD_STEP)
185    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
186    o adjoint store dir. adjusted accordingly
187    o genmake2
188      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
189    
190    checkpoint58i_post
191    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
192      on wind stress (SEAICEstressFactor defaults to 1.)
193    o Total number of Timers is finite (<=40): comment out 2 non-essential one
194      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
195    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
196      on CS-grid: no longer loosing mass.
197    o exf & curvilinear-grid: no longer modify longitude xC & xG.
198    o pkg/ggl90: fix sloppy output and fix a bug
199    o pkg/seaice: added SEAICEuseEVPpickup parameter
200      - Set to false in order to start EVP solver with
201        non-EVP pickup files when using SEAICEuseEVP
202      - fix sign error in diffusion in seaice_calc_rhs
203    
204    checkpoint58h_post
205    * Modifications for bottom topography control
206      o replace hFacC by _hFacC at various places
207      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
208      o add non-self-adjoint cg2d_nsa
209      o update autodiff support routines
210      o re-initialise hfac after ctrl_depth_ini
211      o works for 5x5 box, doesnt work for global_ocean.90x40x15
212    * Adding verification for 5x5 box (4-layer) bottom topography control
213    
214    checkpoint58g_post
215    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
216       used for mean seasonal cycle, mean diurnal cycle); add an example
217       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
218    o pkg/ggl90:
219      - add parameter (minimum surface kinetic energy)
220      - fix bug (avoiding division by zero)
221    o couple pkg/thsice to pkg/seaice:
222      - modify advection in seaice to accomodate new scalar fields to be advected
223      - only muliDimAdection scheme work with seaice/thsice
224      - mapping of thsice-variables to seaice-variables, back and forth
225      - does not break the verification experiments, but does not give the
226        desired results either
227    o pkg/seaice
228      - make (default) second order advection a bit less confusing?
229    
230    checkpoint58f_post
231    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
232      to pkg/seaice):
233      - new routines thsice_map_exf and thsice_get_exf provide the interface
234      - add an additional formal parameter to thsice_solve4temp
235    o pkg/exf:
236      - add new fields wspeed, snowprecip (to be able to couple to thsice)
237      - correct Stefan-Boltzmann constant
238      - new parameter for longwave surface emittance
239      - separate some stuff from exf_bulkformulae into new routines  
240        exf_radiation, exf_wind
241      - add new parameters and constants: longwave emissivity for ocean, ice
242        and snow, evaporation parameters over ice
243      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
244        either wind from stress or stress from wind
245    o pkg/thSIce:
246    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
247    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
248       and THSICE_CALC_THICKN
249    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
250    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
251      to make debugging easier.
252    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
253    o pkg/bulk_force:
254      - clean-up comments and parameters ;
255      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
256    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
257      generate new output for test-experiment: aim.5l_cs.thSI
258    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
259      testreport accordingly
260    
261    checkpoint58e_post
262    o SEAICE_CGRID adjoint done
263    o R_STAR adjoint implemented.
264      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
265      * need to sort out init. of h0facc, etc.
266    o Make pkg/profile fully independent of ecco,cost, etc. stuff
267      to be able to use it in pure forward.
268    
269    checkpoint58d_post
270    o upgrade simple test-experiment to tutorial example:
271     step.1: duplicate the experiment and (step.2) will remove the old copy.
272      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
273      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)

275      tutorial_global_oce_biogeo    <- copy of dic_example
276      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
277      tutorial_plume_on_slope       <- copy of plume_on_slope
278      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
279      tutorial_global_oce_optim     <- empty for now (David ?)
280      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
281     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
282    o correct a sign problem in cost_scat.F
283    o obcs and ptracers: fix boundary conditions for advections schemes
284      with larger stencil
285    o thsice adjoint: start
286    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
287      completeness
288    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
289      and COSINEMETH_III, add comments in default CPP_OPTIONS.h

291      * avoid extensive recomputatations
292      * fix missing re-init. of gptr (missed by TAF)
293    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
294      me to turn off the excessive output to STDOUT that this package produces
295    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
296      and add those terms in Vector-Invariant formulation.
297    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
298      if the control period (xx_hfluxperiod etc) is 0
299    o in profiles pkg, clean routines and fix details

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

1435    o Will need long integration testing.
1436  checkpoint53b_pre  checkpoint53b_pre
1437    
1438  o created pkg/mom_common in preparation for variable viscosity code  o created pkg/mom_common in preparation for variable viscosity code
