4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    o add ability to read bathy, salt, and theta using MNC (off by def)
7    o add flooding algorithm and advection of HSNOW for pkg/seaice;
8      both are turned off by default and do no change any results
9    o seaice advection with pkg/thsice: a step toward the use of non-linear
10      advection scheme, but #ifdef or commented out for now (requires more EXCH).
11    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
12      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
13      in natl_box (affects results @ truncation level: update output.txt)
14    o multi-threading and IO:
15      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
16      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
17        (needed to work with SingleCpuIO): tested in all verif. exp.
18    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
19      affects the results (but none of the verification test uses this scheme).
20    o Adding some pkg/diagnostics capability to pkg/seaice
21      (will certainly be subject to changes)
22    o ctrl: adding new control variables:
23      lwflux, lwdown, evap, snowprecip, apressure, runoff
24    
25  untagged  checkpoint58q_post
26    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
27      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
28      high_res_cube configuration by 4% on Columbia.
29    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
30      add (in global_with_exf/code) a version of EXF_INTERP_READ without
31      dynamical allocation (seems to work in multi-threaded).
32    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
33      single CPU io) so that TAF does not have to see EESUPPORT.h
34    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
35    
36    checkpoint58p_post
37    o obcs: stop if obcs is used with useCDscheme = .true.
38    o shelfice:
39     - fix a sign error so that no slip at shelfice interface works
40     - remove stop for combination non-hydrostatic code and shelfice. That does
41       not mean, that the results are correct, but at least they are numerically
42       stable
43    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
44    o added adjoint exch routined for all exch*3d* routines
45      and updated flow directives
46    
47    checkpoint58o_post
48    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
49      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
50    o change controling S/R for writing pickup file (new S/R do_write_pickup)
51      and clean-up reading/writing of pickup files.
52    o fix local version of read/write pickup (NH part) in rotating_tank/code
53    o simplify EXCH interface:
54     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
55     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
56    o added the regrid package
57    o shelfice:
58     - add a simple boundary layer scheme to reduce noise
59     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
60    
61    checkpoint58n_post
62    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
63       local variable (not in common block).
64    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
65      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
66      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
67        to work with SingleCpuIO.
68    o add "_d 0" to real constant of pkg/cfc subroutines ;
69       update exp. cfc_exemple & tutorial_cfc_offline output files.
70    o multi-threading and IO:
71      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
72        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
73      - barrier before and after reading.
74      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
75      - avoid using MDS_WRITELOCAL for LAND pkg output.
76      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
77        common-block variables ; Allows multi-threading with master-thread IO.
78    o change default MAX_NO_THREADS from 32 to 4 ;
79      and stop cleanly when MAX_NO_THREADS is too small.
80    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
81    
82    checkpoint58m_post
83    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
84       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
85    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
86       keep global_ocean.90x40x15 (for AD testing) with former secondary test
87       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
88    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
89        add MITgcm_tutorials (= code + all the tutorials)
90    o ecco, option to compute cost for total ssh (mean+anom)
91    o consistent with addition of ptracer and ssh in pkg/profiles
92    o profiles: adding ptracer and ssh
93    o testreport: change multi-test output-file name
94      (from output.txt.{name} to output.{name}.txt)
95    o profiles: now ok for mutli-tiles case
96    o seaice: add 4 parameters for different advection schemes for area,
97      (effective) seaice thickness, enthalphy, and snow height. Their default
98      is the standard parameter SEAICEadvScheme
99    o calc_gw:
100     - add cosFacU in zonal viscous flux (harmonic.visc.).
101     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
102       of tutorial_plume_on_slope.
103    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
104    o calc_gw: true flux-form, account for horizontal grid spacing.
105      update rotating_tank results, but not plume_on_slope (affected at
106      truncation level, 11 digits).
107    
108    checkpoint58l_post
109    o calc_gw:
110     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
111     - remove side-drag for now (need to fix it); update plume_on_slope results.
112     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
113    o commit code to make SST/SSS weights spatially variable
114      (based on either variable in-situ or variable initial T/S weights)
115    o pkg/ecco:
116      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
117        now based on horizontally varying weights wthetaLev, wsaltLev
118      * cost_averagesflags now returns year indices in addition to day, month
119      * sflux balance is performed on annual basis
120        (sflxumm, sfluxmm2, bal_sfluxmm)
121      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
122        including separate counting and multipliers
123    o pkg/rbcs
124      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
125    
126    checkpoint58k_post
127    o testreport:
128     - always build in dir. "build" (if not there, mkdir build instead of building
129       & running in input)
130     - run in dir run (if it exists), in build otherwise.
131     - call prepare_run (if input/prepare_run exists)
132     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
133    o pkg/exf modifications to interpolation and rotation routines for more
134       reasonable treatment of North Pole singularity: for tracers North Pole
135       value is set to northernmost zonal-mean value, for zonal velocity it is
136       set to zero, and for meridional velocity it is set to northernmost value.
137    o pkg/exf/exf_check_range.F
138     - add tile index to diagnostics and move stop statement to the very
139       end of the routine.
140    o pkg/diagnostics: (diagnostics_main_init.F)
141      define title of isomorphic variables according to the current config.
142    o pkg/thsice with pkg/seaice dynamics:
143    - fix domain of computation (interior only, required for exf) and do exchanges
144    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
145    o towards a standard way of dealing with multi-threading in MONITOR
146      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
147    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
148       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
149    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
150    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
151    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
152       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
153    o tracer advection:
154     - clean-up and simplify calc_common_factors.F
155     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
156       advection subroutine (but still not used within DST advection S/R)
157    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
158    
159    checkpoint58j_post
160    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
161      from file (collects calls previously in FORWARD_STEP)
162    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
163    o adjoint store dir. adjusted accordingly
164    o genmake2
165      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
166    
167    checkpoint58i_post
168    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
169      on wind stress (SEAICEstressFactor defaults to 1.)
170    o Total number of Timers is finite (<=40): comment out 2 non-essential one
171      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
172    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
173      on CS-grid: no longer loosing mass.
174    o exf & curvilinear-grid: no longer modify longitude xC & xG.
175    o pkg/ggl90: fix sloppy output and fix a bug
176    o pkg/seaice: added SEAICEuseEVPpickup parameter
177      - Set to false in order to start EVP solver with
178        non-EVP pickup files when using SEAICEuseEVP
179      - fix sign error in diffusion in seaice_calc_rhs
180    
181    checkpoint58h_post
182    * Modifications for bottom topography control
183      o replace hFacC by _hFacC at various places
184      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
185      o add non-self-adjoint cg2d_nsa
186      o update autodiff support routines
187      o re-initialise hfac after ctrl_depth_ini
188      o works for 5x5 box, doesnt work for global_ocean.90x40x15
189    * Adding verification for 5x5 box (4-layer) bottom topography control
190    
191    checkpoint58g_post
192    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
193       used for mean seasonal cycle, mean diurnal cycle); add an example
194       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
195    o pkg/ggl90:
196      - add parameter (minimum surface kinetic energy)
197      - fix bug (avoiding division by zero)
198    o couple pkg/thsice to pkg/seaice:
199      - modify advection in seaice to accomodate new scalar fields to be advected
200      - only muliDimAdection scheme work with seaice/thsice
201      - mapping of thsice-variables to seaice-variables, back and forth
202      - does not break the verification experiments, but does not give the
203        desired results either
204    o pkg/seaice
205      - make (default) second order advection a bit less confusing?
206    
207    checkpoint58f_post
208    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
209      to pkg/seaice):
210      - new routines thsice_map_exf and thsice_get_exf provide the interface
211      - add an additional formal parameter to thsice_solve4temp
212    o pkg/exf:
213      - add new fields wspeed, snowprecip (to be able to couple to thsice)
214      - correct Stefan-Boltzmann constant
215      - new parameter for longwave surface emittance
216      - separate some stuff from exf_bulkformulae into new routines  
217        exf_radiation, exf_wind
218      - add new parameters and constants: longwave emissivity for ocean, ice
219        and snow, evaporation parameters over ice
220      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
221        either wind from stress or stress from wind
222    o pkg/thSIce:
223    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
224    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
225       and THSICE_CALC_THICKN
226    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
227    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
228      to make debugging easier.
229    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
230    o pkg/bulk_force:
231      - clean-up comments and parameters ;
232      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
233    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
234      generate new output for test-experiment: aim.5l_cs.thSI
235    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
236      testreport accordingly
237    
238    checkpoint58e_post
239    o SEAICE_CGRID adjoint done
240    o R_STAR adjoint implemented.
241      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
242      * need to sort out init. of h0facc, etc.
243    o Make pkg/profile fully independent of ecco,cost, etc. stuff
244      to be able to use it in pure forward.
245    
246    checkpoint58d_post
247    o upgrade simple test-experiment to tutorial example:
248     step.1: duplicate the experiment and (step.2) will remove the old copy.
249      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
250      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
251      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
252      tutorial_global_oce_biogeo    <- copy of dic_example
253      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
254      tutorial_plume_on_slope       <- copy of plume_on_slope
255      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
256      tutorial_global_oce_optim     <- empty for now (David ?)
257      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
258     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
259    o correct a sign problem in cost_scat.F
260    o obcs and ptracers: fix boundary conditions for advections schemes
261      with larger stencil
262    o thsice adjoint: start
263    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
264      completeness
265    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
266      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
267    o ptracers adjoint:
268      * avoid extensive recomputatations
269      * fix missing re-init. of gptr (missed by TAF)
270    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
271      me to turn off the excessive output to STDOUT that this package produces
272    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
273      and add those terms in Vector-Invariant formulation.
274    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
275      if the control period (xx_hfluxperiod etc) is 0
276    o in profiles pkg, clean routines and fix details
277    o in ecco pkg, reading ssh data:
278      fix problem in case the model does not start at iter0=0
279    o fix mnc-pickup/restart for ptracers
280    o new package prifiles:
281      code to compute profile-based cost by Gael Forget
282      (modifs in ecco, ctrl, autodiff)
283    o Benign bug fix in initialization (spotted by M. Mazloff) of
284      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
285    
286    checkpoint58c_post
287    o adjoint: finish NLFS adjoint and provide reference output in
288      verification/global_ocean.90x40x15/results_ad_nlfs
289    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
290      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
291      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
292      with SEAICE_CGRID defined.
293    o move calendarDumps from "data" to "data.cal" and clean-up the code
294      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
295    o add useEXF & useCAL flags (for now, set in hard-coded way)
296    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
297      (were missing in NH mode, and wrong in quasihydrostatic mode).
298      waiting for Chris updated version of calc_gw to add those CALLs.
299    o fix bug in quasihydrostatic S/R ;
300      add a test for this option: global_ocean.90x40x15.qshyd
301    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
302      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
303    o add on/off flag useOffLine for package OFFLINE
304    o seaice:
305      - modify advection so that it works also on the C-grid
306      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
307        problem in multi-tile runs with C-grid
308      - add flags for clipping ice velocities and/or masking solver forcing
309      - fix drag (ocean on ice) formulation and a bug that caused noise in the
310        C-grid solver
311      - added a few comments to seaice_diffusion.F
312      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
313        are now exclusive)
314      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
315        required re-ordering the code a little:
316       + make DAIRN global variable (defined in SEAICE)
317       + move computation of the viscosities eta and zeta into a new separate
318         routine (because I need to recompute them in seaice_ocean_stress.F)
319    
320    checkpoint58b_post
321    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
322      update output.txt of exp. aim.5l_cs.thSI
323    o various mnc cleanups and improvements:
324      + shrink lookup tables by factor of ~4
325      + better error reporting when running out of lookup space
326      + able to handle longer path/file names (up to 500 chars)
327    o adjoint:
328      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
329      - TBD: "hidden" mom_vecinv recomp. in dynamics
330    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
331     (allow to differentiate between forcing components using new integer flags:
332      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
333     and add new flag to put Dissipation tendency out of Adams-Bashforth.
334    o ecco
335      - enable trend removal from SSH anomaly obs.
336    o adjoint
337      - a fix for PmEpR when #undef EXACT_CONSERV
338      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
339      - try to fix "hidden" recomp. in forward_step for NLFS
340        (NLFS seems broken sometimes after I checked it in)
341    o seaice:
342     - add c-grid version of the dynamic solver:
343       + three new routines that are the c-grid substitute lsr, dynsolver
344         and ostres
345       + put a few fields that were local to dynsolver into global common
346         blocks, so that I can move the computation of stresses etc into
347         seaice_lsr (saves coding but may break the adjoint).
348     - replace more hardwired parameters by runtime parameters
349     - add ice masks that mask the rhs of the implicit solvers where there
350       is no ice (commented out in seaice_dynsolver, because i am not sure
351       if this works properly), eventually this should replace the clipping
352       of ice velocities in seaice_dynsolver to +/-40cm/s.
353    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
354      include it only where its needed
355    o move balancing of fluxes before the call of external_forcing_surf
356    o seaice:
357      - correct units of turning angles (now they are really in degrees)
358      - move computation of GWATX/Y out of main routine into dynsolver
359      - initialize GWATX/Y in seaice_init
360    o Apply mask on Fresh-Water flux (needed for SSH forcing).
361      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
362    o seaice: add runtime flags for turning angles (default to zero)
363    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
364      and trend from exf forcing and ctrl control adjustments
365    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
366      (since checkpoint57x_post)
367    o change the default rotation period to 86164.s = the Earth rotation
368    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
369      and based on a reference stratification. Tested within hs94.cs-32x32x5.
370    o seaice advection: add code for choosing between the default (2nd order
371      central differences) and multiDim advection schemes provided by
372      pkg/generic_advdiff
373    o seaice:
374      - removed all references to SEAICE_GRID.h fields from
375        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
376        (cubed-sphere configuration will change a little)
377      - grid computations in seaice_init are obsolete now.
378      - cleaned up code a little so that is easier to read (hopefully).
379      - added new (better?) discretizations of default advection and diffusion
380        (turn on with SEAICEuseFluxForm)
381      - replace 1 in 3d global fields by kSurface in growth.F
382      
383    checkpoint58a_post
384    o seaice:
385      - bug fix in advect.F
386    o shelfice:
387      - separate shelfice load anomaly from pload (breaks with time
388        dependent forcing), => introduce constant field shelficeLoadAnomaly.
389        Its default is 0., but it may be computed more cleverly from (unknown)
390        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
391        done offline. A good approximation of the pressure load anomaly is
392        necessary to avoid large initial adjustment processes underneath
393        deep-reaching shelfice.
394      - small fix in ISOMIP shelfice_thermodynamics
395      - add more sophisticated thermodynamics of Hellmer (1989), this is
396        now the default
397      - give a few constants more intuitive names
398    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
399      if bulk formulae are used in long integration (especially EmPmR). Turn
400      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
401      if balancePrintMean, the imbalance that is substracted is printed to
402      STDOUT.
403    o fix bug (typo) in obcs_apply_eta.F
404    o add a new package shelfice which enables us to model the circulation
405      underneath shelf-ice with draughts of hundreds of meters.
406     - works
407     - to do: + include improved thermodynamics
408              + check whether kSurfC (from model/inc/SURFACE.h) can be used
409                instead of new field kTopC
410              + can we use topoFile, Ro_surf and existing code in ini_depth.F
411                instead of new field R_shelfIce and new code in ini_depth.F
412                and ini_mask_etc.F?
413              + adjust vertical mixing schemes?
414    o seaice pkg:
415     - add a cpp-flag to include a simple formula for a salinity dependent
416       freezing point of sea water at the surface
417     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
418       meridional stresses are now different (and hopefully correct)
419    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
420       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
421       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
422    o pkg/diagnostics: add options and parameters for regional-statistics
423       diagnostics ; define regions by reading a region-mask from a file
424       (might add other options later)
425    o pkg/bulk_force:
426     - add option and parameters to use AIM surface-flux formulae.
427     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
428       others forcing fields (defined in PARM05, parameter file "data") are loaded
429       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
430     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
431     - use the right EXCH call for uwind,vwind (to work on CS-grid).
432     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
433       and parameters (note: calcWindStress replaces .NOT.readwindstress).
434     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
435    
436    checkpoint58
437    o add "--embed-source" option to genmake2 which, when the supporting
438      tools can be compiled (as determined by genmake2) will turn on the
439      embed_files package which then embeds the entire MITgcm source code
440      (*.[fFhc] + Makefile) used for the build within the executable
441      - requested by CNH but off by default
442      - adds a paltry <9MB to the mitgcmuv executable in most cases
443      - only writes the output when useEMBEDSRC in eedata is true
444    o clean up 3-dim. relaxation codes:
445      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
446      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
447      * Thanks to Tom Haine for testing!
448    
449    checkpoint57z_post
450    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
451      affects output (@ truncation level) of exp. plume_on_slope ; updated.
452    o fix the pickup behavior for obcs in combination with ptracers
453    o fix a bug in ptracers_external_fields_load
454    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
455      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
456    o transfered surface NH pressure to eta field (if exactConserv).
457    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
458         and update lab_sea output.txt file.
459    o completing 3-dim. relaxation code: additional term
460         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
461      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
462      * At compile time, in "EXF_OPTIONS.h" set
463          #define  ALLOW_CLIMTEMP_RELAXATION
464          #define  ALLOW_CLIMSALT_RELAXATION
465      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
466          tauThetaClimRelax3Dim = 15552000.0,
467          tauSaltClimRelax3Dim  = 15552000.0,
468      * 3 cases:
469          1) Use a constant-in-time 3-dim. field
470          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
471          3) Real-time relax. to time-evolving prescribed field
472    o Adding Laplacian-type smoothness constraint on
473      initial and boundary (forcing) controls (ic, bc)
474      * enable at compile-time via
475        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
476      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
477      * Absolute scale somewhat unclear so far
478      * no area weighting was included since no other cost term does so far
479    
480    checkpoint57y_post
481    First step for a NLFS adjoint
482    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
483    o new init. routines for calc_r_star, calc_surf_dr
484    o still need to deal with ini_masks_etc
485    o testreport seemed happy
486    checkpoint57y_pre
487    
488    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
489    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
490    o add new offset feature to offline pkg (plus minor cleanup)
491    o cfc fixes for final year of integration
492    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
493      be in GCHEM_OPTIONS).
494    
495    checkpoint57x_post
496    o fix testreport Pb in multiple test experiment.
497    o cleanup our namelist syntax in verification:
498      - make it more F95 standards compliant (some work still needed)
499      - allows the vast majority of our tests to work with gfortran
500    o Non-Hydrostatic:
501     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
502     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
503    o Allow to apply AB on T,S rather than on AB(gT,gS):
504     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
505     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
506       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
507     - need a "clever" read_pickup to restart from the other AB formulation
508    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
509    o remove some unused variables (reduces number of compiler warnings)
510    o adjoint
511      * Disable useVariableViscosity for adjoint for time being
512        (there are a number of extensive recomputations)
513      * Initialize certain variables needed for adjoint
514    
515    checkpoint57w_post
516    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
517                 fix the singleCpuIO RS version of MDSWRITEFIELD
518       and add a WARNING if using globalFiles=T with multi-processors.
519    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
520      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
521    o tracer advection scheme:
522      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
523       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
524       was not very convenient).
525      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
526       (further tests needed for the implicit DST & Flux-Limiter schemes).
527    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
528      and sRef for convenience, handy, when you want to initialize
529      ptracers in a large domain with a constant non-zero value. Also,
530      untangle ptracers_init.F a little.
531    
532    checkpoint57v_post
533    o change dome exp. to use variable viscosity in side-drag terms.
534    o remove all the files from the cfc_offline test since they are now
535      incorporated into tutorial_cfc_offline which has been producing
536      identical results for a few days of testing
537    o add new parameter: sideDragFactor to enable half-slip-side BC
538      and change side-drag S/R to use viscosity from mom_calc_visc
539      (can switch back by setting sideDragFactor=0.); affects results at
540      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
541       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
542    o vorticity & strain are now computed without masking, to account for
543      no-slip-side BC in variable viscosity calculation ; mask is applied
544      anyway later on, before computing advection/coriolis terms.
545    o modify exp4 to test new obcs support for reading from external files
546      and for passive tracers
547    o fix behavior of ptracers_monitor when monitor output is written to a
548      netcdf-file; still not independent of monitor.F (writes in the same
549      file).
550    o change default value of tRef (put a uniform, meaningful value for ocean
551      & atmos) and initialize sRef (was missing, as Martin mentioned).
552    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
553      to be proportional to enstrophy dissipation length.  Thus,
554       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
555      This is now consistent with Smagorinsky and with the manual.
556    
557    checkpoint57u_post
558    o OBCS and PTRACERS: add open boundary support for passive tracers
559      - either use homogenous (pseudo) v.Neumann conditions or prescribe
560        OB-values from file; this is not different from the way theta and salinity
561        are treated
562      - however, Orlanski-radiation conditions are not supported, and the model
563        will stop if you use pTracers and Orlanski at the same time.
564      - beefed up the rountine obcs_external_fields_load: now only those open
565        boundary values are overwritten with values from files for which there
566        are really files, otherwise the OB-fields remain untouched. This makes
567        it possible to use different OBs at different ends of the domain (as
568        with EXF)
569    o reduce number of exch calls in shap_filt (s2).
570    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
571      truncation level) 4/5 MLAdjust test results (11&12 digits match).
572    
573    checkpoint57t_post
574    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
575    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
576      same truncation, independent of the face number: affects affects several
577      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
578    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
579      note that biharmonic viscosity + no-slip was not tested in any experiment.
580    o fix bug in non-linear free-surf side-drag ; generate new output for
581      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
582    o make mnc honor the writeBinaryPrec flag for most kinds of output
583    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
584    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
585      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
586    o add brackets in multi-terms sum to get same truncation, independent of
587      the face number (manage to get exactly same value of gU,gV at the cs-edge)
588      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
589    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
590      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
591      a maximum grid-scale Reynolds number.  Also, changes all length calculations
592      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
593      Suggested values of viscosity parameters found in mom_calc_visc.
594      Many new viscosity diagnostics available.
595    
596    checkpoint57s_post
597    o Add clearing-house for viscosity calculations, mom_calc_visc and
598      correct numerous bugs in LeithD and Smagorinsky discretizations.  
599      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
600      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
601      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
602      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
603      The Strain-Tension form is now called with useStrainTensonVisc=.true.
604      ViscAhStrain and viscAhTension are now retired.
605    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
606    o In response to JMC's bug report, genmake2 now ignores any soft-links
607      that it finds in the *current* directory when searching for files.
608      Soft-links found in any other source directories will still work as
609      they did before.
610    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
611      a C routine to unlimit the stack size
612    o mnc-ify pkg/aim snapshot vars
613    o mnc-ify pkg/land as requested by Daniel
614    o various changes to mnc including:
615      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
616      - output can now be grouped so that all files within a group
617          change the ITER portion of their names in lock-step together
618      - can now read ("global") PER-FACE (in addition to PER-TILE) files
619          and works with both EXCH1 and EXCH2 (but needs more testing)
620      - writing works for all verification test cases w/ g77 on Linux
621    
622    checkpoint57r_post
623    o make MNC variable initialization happen earlier
624    o add diagnostics for (almost) each term of the momentum Eq.
625    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
626    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
627    o remove MINIMAL_TAVE_OUTPUT option ;
628      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
629    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
630      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
631    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
632    o add time-dependent SST, SSS control
633    o cost terms in ecco/ modularized (new cost_generic.F)
634    o cost_averages routines are modularized (new cost_averagesgeneric.F)
635    o new infrastructure for seaice model vs. obs misfits in seaice/
636      * driver from the_main_loop.F is seaice_cost_driver.F
637      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
638      * gradient check in Exp. 6a of natl_box_adjoint/
639    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
640      (see README file)
641    
642    checkpoint57q_post
643    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
644    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
645      - bug was reported by Jean-Michel and Ian Fenty
646    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
647      update exp. cpl_aim+ocn output.
648    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
649      Needed for high-res. runs with large global files
650      to be able to limit tapelev size
651    o Changed some tests for adjoint:
652      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
653      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
654      * global_ocean.90x40x15/ back to default 3-level checkpointing
655    o Modifications to enable scripted COMMON to MODULE conversion
656      * verification/OpenAD/code/ has necessary scripts and description;
657      * converts, compiles and runs successfully;
658    
659    checkpoint57p_post
660    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
661    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
662      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
663    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
664    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
665      (was already the case for dissipation with mom_vecinv,
666       and also the case for grad.PhiHyd when staggered-timeStep)
667      This will allow to put dissipation out-off the AB time-stepping.
668     Unfortunately, affects truncation error. Update output of exp. that "fails"
669      (cg2d matching number) and leave the others for later: front_relax(10),
670      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
671      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
672    
673    checkpoint57o_post
674    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
675      (2) its ready to be documented during the 20050801 DocFest
676    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
677      for ideal_2D_oce and lab_sea on linux_ia32_g77
678    o set to #undef CTRL_SET_OLD_MAXCVARS_30
679      in global1x1_tot/code_seaice_adj to access indices 32, 33
680      (worth another tag)
681    
682    checkpoint57n_post
683    o adding precip control xx_precip 32
684    o adding swflux control xx_swflux 33
685    o Replacing 10 forcing penalty cost routines by 1 generic.
686    o Implementing partitioning in time-mean and variable adjustment
687      for atmos. state.
688    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
689    o in natl_box_adjoint:
690      * updated exp 1 to 10
691        (but does not have time-mean vs. variable split results yet)
692    o updated global1x1/*_seaice_adj/
693      to incorporate latest changes
694    o enable useSingleCpuIO for mdsio vector routines
695      (applies in particular to tapelev I/O)
696    o removed inefficient K-loop in all active_file*control*.F
697    
698    checkpoint57m_post
699    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
700      and advect_cs (use EXCH-2 and standard cs-32 grid files).
701    o pkg/exch2: filling of face-corner halo regions is optional
702      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
703    
704    checkpoint57l_post
705     tag before updating tutorials (pre-release-2)
706    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
707       for output and interpolation of input fields onto model grid)
708    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
709       Affects results of exp. rotating_tank ; update output.txt.
710    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
711          and taking the square quantity and/or using a fraction-weight field.
712    o fix aim_diagnostics_init.F mate numbers.
713    o add mnc output capability to diagnostics/diagstat and update
714      our cvsignore files for the ACSII output generated
715    
716    checkpoint57k_post
717    o lab_sea now uses diagnostics package and provides a suite of
718      new EXF diagnostics output.
719    
720    checkpoint57j_post
721    o exf
722      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
723        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
724        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
725      * extended diagnostics output
726        - now includes all EXF variables
727        - hs, hl moved to common block
728        - separate S/R for diagnostics, called after ctrl vector is added
729        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
730        - EXFqnet contains true Qnet (i.e. includes qsw)
731      * updated verif. lab_sea, global_with_exf
732      * Rearranging hflux (exf_mapfields -> exf_getforcing)
733        to ensure that diagnostics sees a true EXFqnet
734    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
735    o diagnostics pkg: change pointers so that 1 diagnostic can be used
736      several times with different frequencies.
737    o mnc-ify the thsice package as requested by Daniel Enderton
738      - the monitor--MNC output needs work
739      - many attributes need to be added (most are currently blank)
740    o mnc-ify theaim_v23 package as requested by Daniel Enderton
741      - many attributes need to be added (most are currently blank)
742    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
743    o add Sadourny like discretization to the 4th.O vorticity advection scheme
744    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
745      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
746         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
747    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
748     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
749    
750    checkpoint57i_post
751    o Diagnostics package was changed: diagnostic allocation is now deactivated
752      by setting an empty file name in the namelist (used to be by setting 0 frequency)
753    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
754      add 1rst Order upwind vertical Shear.
755    o add a quick fix for A/B checkpointing in OFFLINE mode
756    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
757      end-run around the C/Fortran linking horror in eesup/src/timers.F
758    o added pkg/runclock: allows user to terminate run based on wall clock
759    o added non-hydrostatic scaling parameter: nh_am2
760    o pkg/my82: futile attempt to make results compiler-independent by adding
761      some "_d 0", etc. no effect.
762    o for mnc output, fill the 'T' coordinate var with myTime and create a
763      separate 'iter' variable for iteration count
764    o pkg/diagnostics:
765      add new capability: output of Global/Regional & per-level statistics ;
766      tested against monitor output (including land & thSIce) on various exp.
767    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
768    
769    checkpoint57h_done
770      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
771      data.diagnostics, data.gchem, data.ptracers) is done.
772    
773    o pkg/diagnostics: prepare for Global/Regional statistics.
774      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
775    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
776      and rename it: DIFFERENT_MULTIPLE
777    
778    checkpoint57h_post
779    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
780    o pkg/diagnostics: change output frequency, now in seconds (instead
781      of Nb of iterations). This requires to change data.diagnostics.
782    checkpoint57h_pre
783    
784    o in mnc, let the user create the output dir if both mnc_outdir_date
785      and mnc_outdir_num are false
786    o add fflags() to pkg/diagnostics which allows one to specify, on a
787      per-file basis, the file precision [default behavior is unchanged]
788    o added diagnostics to pkg/kpp, including computation of mixed layer
789      depth based on a temperature/density criterion
790    o updated verification/natl_box to test the new pkg/kpp diagnostics
791    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
792    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
793    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
794      not mnc -- this mistake was found by JMC and is now corrected
795    
796    checkpoint57g_post
797    o add Adams-Bashforth 3rd Order time stepping:
798      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
799      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
800    checkpoint57g_pre
801    
802    o make lambda[Theta,Salt]ClimRelax spatially varying
803      (default remains spatially uniform constant based on tau)
804    o added new control variables
805      * init. uVel, vVel, etanN
806      * lambda[Theta,Salt]ClimRelax
807    o separate masks used for ctrl_pack/unpack 'from write_grid' output
808      (suggested by G. Forget)
809    
810    checkpoint57f_post
811    o add parameter "baseTime" = model base time = time at iteration zero
812      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
813      account for baseTime shift
814    o move Coriolis arrays from PARAMS.h to GRID.h
815    checkpoint57f_pre
816    
817    o mnc-ifying the seaice package
818    o introduced an alternative length scale calculation for use in the limiting
819      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
820    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
821    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
822      as well as grad(vort3).  Made it compatible with both approximate form
823      for the cubed sphere and full form of these gradients.  Added flag
824      useFullLeith to select between approximate and full form.  
825    o add "d0" in getcon.F to reduce differences between compilers/platforms
826      update output.txt of exp. fizhi-gridalt-hs
827    o change port_rand funtion to allow to set the seed.
828    o fix obscure MNC bug involving conversion between reals and integers
829      - it caused no problems with certain (eg. gcc, ifc) compilers but the
830        new version is now more standards-compliant
831    o adjoint-related modifications
832      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
833      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
834      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
835    
836    checkpoint57e_post
837    o Adding eddy stress controls a la Ferreira et al.
838    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
839    
840    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
841      update output.txt of exp. fizhi-gridalt-hs
842    o add more "Z" dimensions and associated coordinate vars to MNC
843    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
844    o parameter calendarDumps: when set, approximate months (30-31 days) and years
845      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
846      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
847      months and years.  Requires pkg/cal.
848    o diagnostics: add pickup functionality
849      - off by default for backwards compatibility
850      - current version only uses MDSIO -- MNC will be added
851    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
852    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
853    
854    checkpoint57d_post
855    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
856    o modify verification/ideal_2D_oce so that it tests the creation of mnc
857      output from the diagnostics package
858    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
859    o make genmake2 more portable by using ".$FS" instead of ".f" for more
860      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
861    o add coordinate variables to the MNC output from the diagnostics package
862    o change MNC-flags default value: true when useMNC=TRUE
863    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
864      the ability (off by default) to read the grid information using MNC
865    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
866    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
867    o do snap-shot diagnostics at the middle of the time-interval (instead of
868      at the end).
869    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
870      new test for AIM with thSIce + slab-ocean
871    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
872    o move state variable diagnostics to the beginning of the time step ;
873      (note: still needs some work specially for snap-shot diagnostics)
874      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
875    
876    checkpoint57c_post
877    o Change testing option (-ieee) to get closer agreement between g77 & ifort
878    o generate new output.txt files on faulks with g77 & the new -ieee option
879    checkpoint57c_pre
880    
881    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
882      update output.txt of exp. global_ocean.90x40x15
883    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
884      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
885    o add saltFlux(+File) forcing capability with periodicExternalForcing
886    o allow to use pkg diagnostics for GM-Redi & ThSIce output
887    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
888    o improvements for the MNC output from DIAGNOSTICS:
889      - correct handling of the unlimitied dimension
890      - all dims now have associated coordinate variables
891      - variables located at U, V, and Corner ("Z") points are now written
892        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
893        *all* data points are output
894    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
895    o added pkg/seaice/seaice_monitor.F
896    o mdsio_readfield.F can now read files visible only to master MPI process.
897    o pkg/seaice: some test code for ice-modified ocean stress
898    o exf_getffields interpolation defaults to bilinear for all scalar forcing
899      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
900      spurious negative numbers for precipitation and humidity.  Will cause
901      some small numerical differences for integrations using pkg/exf/exf_interp.F.
902    o pkg/ctrl/
903      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
904        May be enabled via doPackDiag
905      *  introduce z-scaling of
906         + gradient (doZscalePack) and
907         + control (doZscaleUnpack)
908    o pkg/mdsio/
909      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
910      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
911    
912    checkpoint57b_post
913    o simplify options in diagnostics_fill arguments (remove weird combinations)
914    o fix MNC coordinate variables so that they now contain per-face index
915      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
916      general, EXCH2 grids are only aligned to a "local" coordinate system
917    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
918    o Implement instantaneous output within pkg diagnostics:
919      setting a negative frequency in data.diagnostics produces
920     "snap-shot" output (as opposed to time-average if freq > 0)
921    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
922      NOTE: change ptracer diagnostics name: use 2 characters to work with
923            more than 9 tracers. Add also diagnostics of advect & diffus flux.
924    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
925      becomes the coordinate variable for the 'T' dimension
926    o add CF-style coordinate variables to MNC
927      - just a first cut:  numbers are meaningless on the cubesphere and
928        missing along the T axis but otherwise it works!
929    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
930    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
931    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
932      this is based directly on what the model compute, so that the content of
933      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
934    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
935    o clean up build options files for SunOS, in particular
936      - remove -traditional from xmakedepend
937      - change -xarch=v9 to -xarch=native for f77
938      - restore use of make (not gmake)
939      - add CC=gcc if using g77
940    o changes per discussion of AM, JMC, & EH3 today:
941      - move redundant "grid" variables out of "state" -- in preparation of
942        creating proper CF-style coordinate variables and in recognition
943        that any/all grid variables can be easily copied (eg. w/NCO) from
944        the grid files into any of the other NetCDF files
945      - *always* output grid variables with MDSIO (this will eventually be
946        changed)
947      - output MNC grid file if useMNC is true
948    o every instance of _END_MASTER() has been found and replaced with
949      _END_MASTER( myThid ) in order to satisfy certain picky Sun
950      preprocessors
951    o re-arrange diagnostics pkg initialisation:
952     - allow each package to extend the available diagnostics list
953     - add some checking and fix small problems (multi-threaded, ...)
954     - new S/R diagnostics_fill (replace fill_diagnostics):
955       look through the short list of active diag. (instead of the long list)
956       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
957    
958    checkpoint57a_post
959    o this set of changes restores TAMC compatibility
960      tested for global_ocean.90x40x15 adjoint on trough
961      (what a pain)
962    
963    checkpoint57a_pre
964    o some modifs in tools/build_options for sunos
965    o call ctrl_pack for ctrl at end for optimcycle=0
966    
967    checkpoint57
968    o add horizontal bi-harmonic viscosity for vertical velocity
969      - new parameter viscA4W (defaults to viscA4)
970      - affects only non-hydrostatic code
971      - to be done: no-slip lateral boundary conditions
972    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
973    o implement Implicit Vertical advection for pTracers
974    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
975      (implemented also for implicit vertical diffusion & advection)
976    o OBCS: extend application of tracer open boundary conditions
977      to a strip beyond the boundary of width Olx/Oly
978    o add call monitor to TAF set of required calls (flow directives)
979      and include in natl_box_adjoint
980    o untangle a few ifdefs related to cost, ctrl, autodiff
981      untangel a few ALLOW_ECCO_OPTIMIZATION
982    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
983      (theta2, salt2 in ecco_cost_weights)
984    
985    checkpoint56c_post
986    o OBCS as control variables
987      - update ctrl_ad_diff.list, obcs_ad_diff.list
988      - remove balance of obcs controls from default
989      - fix index bug nobcs in ctrl_init
990      - fix dummy fields filen in ctrl_pack
991      - add dummy weights for obcs
992    o lsopt: comment out fort.94 output
993    o optim:
994      - remove unnecessary header files
995      - adjusted namelists
996      - add xerbla.F to Makefile
997    o exf:
998      - multiple modifications of exf_check_range
999      - unit change in exf_init_runoff from [m/year] to [m/s]
1000    o mdsio:
1001      - i/o-vector change debugLevel from debLevA to debLevB
1002    
1003    checkpoint56b_post
1004    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1005      is called from DO_THE_MODEL_IO
1006      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1007      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1008      - clean up PTRACERS_WRITE_TIMEAVE a little
1009    o add another verification experiment that tests both the cfc-pkg and
1010      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1011      reactive tendencies treated inline with regular timestepping
1012    o testreport previously did a lousy job of comparing small numbers, so
1013      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1014      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1015      testreport.
1016    o ptracers_monitor: bug fix for MPI
1017    
1018    checkpoint56a_post
1019    o GCHEM: finish reorganizating the package
1020      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1021        (introduces another 3D-array for each passive tracer, but only if
1022        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1023        gchemTendency is not needed because the timestep is done separately)
1024      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1025      - GCHEM is now---more or less cleanly---separate from PTRACERS
1026      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1027        so clear to me how that should be done in a general way.
1028    o CFC: improve formatting of output in CFC_ATMOS
1029    o PTRACERS:
1030      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1031        that ALL experiments with ptracers enable can be checked. This makes
1032        GCHEM_MONITOR obsolete.
1033      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1034        monitorFreq
1035      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1036    o add PTRACERS (PTR0[1-5]) to testreport output
1037    o exf_check_range:
1038      * default changed to .TRUE.
1039      * will check values for niter0 if debLevA, every timestep if debLevB
1040      * STOP in exf_check_range if 'out of range'
1041      * range chosen generous to allow for potential extema
1042      TBD: a version with stricter range
1043           permitted range would be runtime parameters
1044    o GMredi:
1045      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1046      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
1047      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
1048    o GCHEM:
1049      - move call to GCHEM_FORCING_SEP, so that it is now called before
1050        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
1051      - introduced a useGCHEM runtime flag and applied it everywhere.
1052      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1053        this flag is now only visible within GCHEM-pkg routines.
1054      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1055        be replaced by a 3D array that is computed before thermodynamics; for
1056        this, the tracer ID iTracer had to be included into the parameter list
1057        of ptracers_forcing
1058      - set up forward_step to call gchem_forcing, that will replace
1059        gchem_forcing_int in ptracers_forcing
1060      - cleaning up
1061    o small cleaning of exch2: remove files that are also in eesupp/src
1062    
1063    checkpoint56
1064    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
1065    o mnc: cleanup "full" files--fixes out-of-memory problem
1066    o ECCO-GODAE
1067      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
1068      * fully merged and updated from SIO code
1069        windstress sign change affects
1070        - exf_inscal_[u/v]stress
1071        - sign of xx_tau[u/v] adjustments
1072        - signs in cost_scat
1073      * ctrl_get_gen: avoid update of tau[u/v] for first few days
1074      * natl_box_adjoint updated and compressed
1075      * 2-level checkpoint switch added
1076        (tested in EXP. 1 of natl_box_adjoint)
1077      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
1078    o SVD
1079      * first complete, non-hacked version for SVD calculations
1080      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
1081        performed via direct access files admtlm_vector.it????
1082        (via ctrl_[un]pack)
1083      * optimcycle is used for ARPACK iteration counter
1084        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
1085      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
1086        and add linear transforms where necessary
1087      * controls are initial/final SST, SSS (can be extended; need to check
1088        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
1089    o mdsio: filename info to both stderr, stdout
1090    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
1091      from sign change
1092    
1093    checkpoint55j_post
1094    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
1095      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1096    o add consistent build directories and .cvsignore files to verification
1097    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
1098    o make all subroutines 30 or less characters in length for certain older
1099      compilers to work (a thorough search only turns up two routines in
1100      pkg/ptracers)
1101    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
1102      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1103    
1104    checkpoint55i_post
1105    o change arrays for total vertical diffusivity (2.D if explicit,
1106      3.D if implicit) ; each ptracer uses its own background value.
1107    o added mnc/NetCDF output capability to ocn_compon_interf
1108      - added bits to verification/cpl_aim+ocn so that it can run on
1109        ITRDA and other clusters without the mpirun "-wd" option
1110    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
1111      configuration
1112    o give MNC the ability to create additional files rather than
1113      exceeding a specified file size limit "MNC_MAX_FILESIZE"
1114      - the default is just less than 2GB which is a practical limit
1115        on many systems
1116    o Compute the non-local term using either KPP vertical diffusivity (=default)
1117       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
1118    
1119    checkpoint55h_post
1120    o add verification test "vermix"
1121    o remove all the *_ioinc flags and replace with the single global
1122      outputTypesInclusive flag
1123    o allow to set a vertical profile of vertical diffusivity for T & S
1124    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
1125    o useMNC moved from data.mnc to data.pkg
1126    
1127    checkpoint55g_post
1128    o Renaming carbon AD experiments to comply with testreport conventions
1129    o Updating adjoint of Held-Suarez hs94.1x64x5
1130    o Fixing directives for non-ECCO forward_step, after ECCO directives
1131      have been fixed to avoid recomp. of do_oceanic_phys
1132      Works well for global_ocean.90x40x15,
1133      but recomp. issue remains for carbon
1134    o Updating adjoint output for natl_box_adjoint after
1135      pkg/ecco has been modified (see taga c55d_post)
1136    
1137    checkpoint55f_post
1138    o rename to timeave_init_fixed
1139    
1140    checkpoint55e_post
1141    o some delicate re-shuffle of store directives to avoid one
1142      extra call of do_oceanic_physics
1143      affects ecco_the_main_loop.F, do_oceanic_physics.F
1144      checkpoint_lev1_directives.h
1145    o NB: this may break global_ocean adjoint temporarily,
1146      but it is clear how to fix it. Will do later, need this now.
1147    
1148    checkpoint55d_post
1149    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1150    o ecco_cost_weights is modified to 1x1 runs
1151    o modifs to allow observations to be read in as
1152      single file or yearly files
1153    o enable to read exf forcing fields as either
1154      single file or yearly files (flag useExfYearlyFields)
1155    checkpoint55d_pre
1156    
1157    o switch between 2-level and 3-level checkpointing
1158    o add ability of MNC to write local and "partial" (eg. 2D slices where
1159      the full 3D field is never actually stored) arrays to NetCDF files
1160      with the correct (that is, the complete multi-dimensional) set of
1161      array indicies
1162      - used in mom_vecinv() to write the diagFreq output
1163      - tested (demonstrated) in verification/aim.5l_cs
1164    o further mnc-ification
1165      - add verification/lab_sea to the list with mnc setups
1166      - fix undefined mnc v-names in cd_code
1167      - add kpp to mnc output (both snapshot and timeave)
1168    o non-hydrostatic code
1169      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1170        in calc_gw.F
1171      - defaults to viscAh
1172      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1173        friction or Leith) in non-hydrostatic mode, as long as there is
1174        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1175    o pkg/cost
1176      extend simple cost functions to treat time mean quantities
1177      (T,U,V) via cost_accumulate_state from cost_tile
1178    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1179        be 2 times larger than the minimum size the advection scheme requires.
1180        now get a perfect conservation of salt in advect_cs test-exp (updated)
1181    o GGL90 (Gaspar's TKE mixed layer)
1182      - add horizontal diffusion of TKE, requires exchanges in
1183        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1184        default. In OPA there is no horizontal diffusion of TKE but the
1185        mixing coefficients are computed from a horizontal average of TKE of
1186        6 points or so. I think that diffusion has a little more physical
1187        justification.
1188      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1189        was in vain)
1190      - mask tke-variable in ggl90_init
1191    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1192    o fix biharmonic diffusion on CS-grid.
1193    o more obcs stuff
1194      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1195        for reading boundary values. This routine is called from
1196        obcs_prescribe_read
1197      - updated obcs_check
1198      - changed sponge layer relaxation parameter units for days to seconds
1199      - turned off sponge layer by default
1200      - changed argument list of OBCS_CALC to myTime+deltaTclock
1201      - fixed about 35 bugs in obcs_external_fields_load
1202    
1203    checkpoint55c_post
1204    o obcs stuff
1205      - new runtime flags useOBCSprescribe, useOBCSbalance
1206      - re-arranged obcs_calc
1207      - moved exf_getobcs to obcs_prescibe_read
1208        obcs_prescibe_read is called after ORLANSKI stuff
1209        and independent of it (executable can contain all).
1210      - updated obcs_check
1211      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1212        These may be necessary only if tangential velocities are
1213        prescribed at OB, not sure, needs testing.
1214    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1215      which simplifies the calls and passes the ifc check-bounds test
1216    
1217    checkpoint55b_post
1218    o add a 2D scalar, Z location, exchange_2 routine.
1219    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1220      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1221      affects advect_cs results (for the wrong reason): update output.txt
1222    o use a more standard discretization for biharmonic viscosity ;
1223     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1224      affects results of dome set-up: update output.txt
1225    o fix gad_advection.F (CubedSphere part), back to version 1.23
1226    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1227    
1228    checkpoint55a_post
1229    o merged code to
1230      * prescribe/read time-dependent open boundaries
1231        (works in conjunction with exf, cal)
1232      * sponge layer code for open boundaries
1233      * each boundary N/S/E/W now has its own CPP option
1234        (healthy for the adjoint)
1235    
1236    checkpoint55
1237    o up-to-date adjoint of previous breaks
1238      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1239      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1240      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1241      - carbon: * remove tr1-related adjoint verification
1242                * add ptracer as control variable
1243    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1244      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1245    
1246    checkpoint54f_post
1247    o in verification/carbin/ remove experiment related to
1248      ALLOW_PASSIVE_TRACER (array tr1 etc)
1249      code_ad/ input_ad/ results_ad
1250    
1251    o add two new packages
1252      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1253        + subject to optimization (memory)
1254      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1255        + subject to reordering (many GOTOs in the original code)
1256        + so far opps is called for every (i,j) point, and then operates in
1257          the vertical; one may want to reorder the scheme in order operate in
1258          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1259          fields)
1260    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1261      - all verification tests compile and run with linux_ia32_g77
1262      - defaults are compatible with current input files--nothing
1263        should change if you were not previously using MNC
1264      - MNC output has been added in numerous places (eg. timeave)
1265        but there are still a few writes not yet do-able with MNC
1266        (this is in progress)
1267      - flags now allow for either/or/both use of MDSIO and MNC and
1268        documentation will soon follow
1269      - numerous small formatting cleanups for ProTeX
1270    o add version info (via BUILD_INFO.h) to MNC and stdout
1271    
1272    checkpoint54e_post
1273    o add two new packages
1274      - pp81 (Packanowski and Philander, 1981), Richardson number and
1275        stratification dependent mixing
1276      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1277      - these scheme operate in a similar manner as KPP (without ghat, of
1278        course), however there is only one diffusivity that is used for both
1279        temperature and salinity (and passive tracers)ç
1280    o add offline package
1281    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1282      provided by Stephanie Dutkiewicz
1283    o genmake2: add ability to search for C compilers and cleanup test output
1284      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1285    
1286    checkpoint54d_post
1287    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1288    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1289      leading to additional shift by 5 days each year of integration
1290       (i.e. leading to considerable offset over the years)
1291    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1292    o start with no AB and no initial filtering (staggerTimeStep):
1293      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1294    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1295      (external loading & cpl import/export stay in forward_step.F)
1296    o update coupling interface to work with new staggerTimeStep
1297    o change MDSIO ptracers_pickup.
1298    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1299    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1300    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1301    
1302    checkpoint54c_post
1303    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1304      this affects (truncation error) output.txt of test-exp:
1305       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1306    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1307    o change Qnet to always be the net heat flux, (+upward).
1308      affects (truncation error) output of natl_box exp.: updated
1309    o define the max number of passive tracers in PTRACERS_SIZE.h
1310    o start to test mnc routinely in exp0
1311    o add sea-ice loading (sIceLoad) as a new forcing field.
1312    
1313    checkpoint54b_post
1314    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1315       impressive on Altix and Opteron systems)
1316    o diagnostics can now write NetCDF files through the mnc package
1317    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1318    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1319    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1320      affects (truncation error) output of lab_sea & natl_box exp.: updated
1321    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1322    
1323    checkpoint54a_post
1324    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1325    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1326    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1327    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1328      + internal_wave (shift in writing cg2d_ini_res)
1329    checkpoint54a_pre
1330    
1331    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1332      - modified verification/lab_sea and natl_box_adjoint accordingly
1333    
1334    checkpoint54
1335    checkpoint53g_post
1336    o prepare splitting of thermodynamics: store convect.counter in common block
1337    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1338      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1339    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1340    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1341    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1342    o restore adjointability
1343    
1344    checkpoint53f_post
1345    o modifications that affect AIM experiment results (update output.txt):
1346      - no advection of S at top interface Nr (pkg/generic_advdiff)
1347      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1348    o AIM pkg:
1349      - include stability function into surf.Flux derivative relative to Tsurf
1350      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1351    
1352    checkpoint53e_post
1353    o merged cylindrical coord configuration
1354    o added rotating_tank experiment
1355    checkpoint53e_pre
1356    
1357    checkpoint53d_post
1358    o faulks upgraded: re-generate output.txt that have changed:
1359       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1360    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1361    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1362    o added Sadourny discretization of Coriolis
1363      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1364      - re-enabled use of omega3 (useAbsVorticity)
1365    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1366      vector-invariant equations
1367      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1368    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1369      hopefully without new bugs
1370      - still to do: biharmonic friction for non-hydrostatic w
1371    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1372    o regenerated output for global_ocean_ebm (using -ieee)
1373    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1374      of mom_common/
1375      - simple re-arrangement of instructions within computing loop
1376    checkpoint53d_pre
1377    
1378    checkpoint53c_post
1379    o new version of coupler for AIM+thSIce and Ocean models
1380     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1381     - land: change Evaporation of snow
1382     - aim with thSIce: fix bug in snow-precip.
1383    o changes to calc_gw.F
1384     - bug fix for w^2 term near the bottom boundary
1385     - (hopefully) improve the lateral slip boundary condtions for use with
1386        partial/looped cells
1387      - because the bug fix changes two verification experiments anyway (exp5
1388        and plume on slope), change the lateral boundary condition from half slip
1389        to the value of no_slip_sides
1390    o ebm package wasnt quite up to the parallel task. Fixed that.
1391    o Adjoint of EBM package + verification
1392      * TLM OK
1393      * ADM not sufficient accuracy yet (needs further testing)
1394    
1395    checkpoint53b_post
1396    o Commiting new energy balance model to repository
1397      * package is pkg/ebm
1398      * verif. is verification/global_ocean_ebm
1399      * references are in ebm_driver.F
1400    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1401    C        Global thermohaline circulation. Part I:
1402    C        Sensitivity to atmospheric moisture transport.
1403    C        J. Climate 12(1), 71-82
1404    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1405    C        Global thermohaline circulation. Part II:
1406    C        Sensitivity with interactive transport.
1407    C        J. Climate 12(1), 83-91
1408    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1409    C        Destabilization of the thermohaline circulation
1410    C        by atmospheric eddy transports.
1411    C        J. Climate 7(12), 1870-1882
1412    o Will need long integration testing.
1413    checkpoint53b_pre
1414    
1415    o created pkg/mom_common in preparation for variable viscosity code
1416    o renamed and split ini_mnc_io
1417    o pkg/land: only liquid water can diffuse or run-off
1418    o AIM using land: soil wetness availability account for snow
1419    o added printMapIncludesZeros to EEPARMS namelist
1420    
1421    checkpoint53a_post
1422    o restore TAMC compatiility for exf_constants.h
1423      (no usage of _d in .h)
1424    o Additional storing in KPP in an attempt to fix
1425      TAMC problem with adjoint of KPP code.
1426      (no success...)
1427      Identical code works fine with TAF.
1428    o Fixed verification/natl_box_adjoint experiments.
1429      Initial conditions for Experiments 4 and 5 are now
1430      set to "SEAICE_initialHEFF=0", which is more reasonable,
1431      and hence gives results closer to that of Experiment 2.
1432      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1433    
1434    checkpoint53
1435    o stable checkpoint with up to date adjoint
1436      TLM tests only run for 1st grdchk at the moment. Its unclear if
1437      this is a code problem or a problem with resetting code for g_
1438      variables that is being autogenerated wrong.
1439      Otherwise:
1440       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1441       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1442         are both still in chaos following their security messes.
1443    
1444    checkpoint52n_post
1445    o various build (mostly genmake2) changes including:
1446      - ability to build/run more easily within Cygwin and MacOS X
1447      - more complicated Makefiles with a stronger dependence on Gnu Make
1448    o pkg/seaice modifications
1449      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1450        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1451        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1452      - changed proxy for geostrophic velocity and updated
1453        verification/lab_sea/results/* accordingly
1454      - removed ADI dynamic solver from pkg/seaice
1455      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1456        they caused a segmentation fault under certain circumstances
1457      - removed unused field WATR
1458    o bug fix in exf-package:
1459      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1460         now reflect that.
1461    o small fixes in the cal-package:
1462      - set reference date to first of January for the 'model'-calendar
1463      - failing of cal_CheckDate in cal_FullDate now actually results in a
1464        warning
1465    o small modifications in exf-package to increase flexibility:
1466      - change climtempfreeze from a constant to a runtime parameter that
1467        is specified in data.exf_clim (default = -1.9)
1468      - introduce runtime parameter windstressmax (default = 2.0) that is
1469        specified in data.exf
1470    o fix in pkg/thsice:
1471      - update Evap (Tsf changes) to be consistent with Latent heat flux
1472      - maintain snow precipitation unchanged (even if Tsf >=0).
1473     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1474    
1475    checkpoint52m_post
1476    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1477      this does not change any of the results, because myIter=0 in swfrac always
1478      lead to jwtype=2 (the default anyway), but the call makes little sense
1479      as a default
1480    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1481    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1482      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1483    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1484    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1485    o extending useSingleCpuIO option to work with new exch2 I/O format
1486      - old-style, missing-tile I/O is still accessible by defining CPP
1487        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1488    o monitor package can write to NetCDF files and/or STDOUT
1489    o fix re-definition bug in MNC_GRID_INIT_ALL()
1490    o doc/api_reference added
1491      - a framework for building an API Reference Manual using all
1492        the "protex" comments embedded in the code
1493      - see pkg/generic_advdiff, pkg/mnc for examples
1494    o MNC:
1495      - make myThid the last argument for all subroutines
1496      - new default for the grid files: NO halos
1497      - add useMNC and other run-time flags
1498      - separate per-file-group handling of the unlimited dimension
1499      - early initialization of MNC w/ flags read at the eeboot stage
1500        and lookup tables set in initialize_fixed
1501      - write all MNC output to a freshly-created directory
1502    o thermodynamics sea-ice (thsice) is now tested with testreport.
1503    o test exp. advect_cs: use the standard cs32 grid ; update output.
1504    o Added functionality to grdchk:
1505      pick global i,j,k position (or nearest wet) where to perform check.
1506    
1507    checkpoint52l_post
1508    o new land formulation:
1509      a) use ground enthalpy as prognostic variable to ensure exact
1510         energy conservation.
1511      b) account for water temperature and for latent heat of freezing
1512         in all processes (rain, run-off, ground storage)
1513      c) compute surface and ground temperature implicitly.
1514    o aim_v23 modification for new land model:
1515      a) Treat separately land / ocean / sea-ice surface fluxes
1516         to allow implicit computation of land & sea-ice surface temp.
1517      b) add snow precipitation.
1518    checkpoint52l_pre
1519    
1520    o fix problem (when 1 tile is empty) in min/max monitor.
1521    o fix bug in timeAve (u,vZetatave in common block)
1522    o no restoring terms under ice for pkg/seaice
1523    o moved SEAICE_DO_DIAGS to S/R do_the_model_io

1525    o change MNC call locations and add coordinate attributes
1526    o mask vorticity at the corner ; affects global_ocean.cs output
1527    o fix ini_curvilinear_grid ; test CS experiments with mpi
1528    o aim.5l_cs: modify sea-ice fraction input file ; update output
1529    o exf: Adding simple range check routine for exf fields after read
1530    
1531    checkpoint52k_post
1532    o removed top-level directory "diags"
1533      - we migrated these functions to pkg/timeave a long time ago
1534    o fixed bug introduced in pkg/monitor
1535    o accuracy ctrlprec = 32 insuffient for gradient checks using
1536      averaged fields (I/O via cost_averages)
1537      -> use ctrl.h in active_file*.F to control I/O precision.
1538    o paramter list of CALL ADTHE_MAIN_LOOP
1539    o added initial do_the_model_io to ecco
1540    o set all ...Freq to zero after cost_final
1541      taveFreq, dumpFreq, pChkptFreq
1542    o MAIN and ECCO differentiability restored
1543    
1544    checkpoint52j_post
1545    o fix nchklev in tamc.h for global_ocean...
1546    o Bringing flow and store directives up-to-date
1547    o Really weird thing!
1548      call do_the_model_io from the_main_loop with parameters
1549      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1550      TAF places a faulty re-call of initialise_varia
1551      after cost_final call which should not be there!
1552    checkpoint52j_pre
1553    
1554    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1555      error messages
1556    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1557    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1558      debug output
1559    o modfied mdsio_writefield.F to handle non-global files under exch2
1560    o update AIM Cubed-Sphere exp (aim.5l_cs):
1561      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1562    o update AIM Equatorial Channel exp:
1563      use standard aim_v23 pkg and change the SST fields to be more realistic.
1564    o globalFile now works with exch2
1565    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1566      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1567    o limit timeave output for hi-res integrations
1568    
1569    checkpoint52i_post
1570    o removed CPP_EEOPTIONS.h from verification/*/code
1571    o updated the tiling for global_ocean_pressure
1572    checkpoint52i_pre
1573    
1574    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1575      the old pkg/aim).
1576    
1577    checkpoint52h_pre
1578    o shortened offending lines in exch2_send_rx?.template
1579    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1580    o genmake2: add build & execute test for NetCDF code
1581    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1582      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1583    o added useSingleCPUIO flag to monitor.F and mon_out.F
1584    o added temporary hack for sea-ice dynamics on the cube:
1585      metric terms are ignored and it is assumed that
1586      there is no sea-ice on cube faces 1, 2, 4, and 5.
1587    
1588    checkpoint52f_post
1589    o added exch2 cube routines to pkg/exch2
1590    o modified hs94.cs-32x32x5 to use it
1591    o added new grid files to hs94.cs-32x32x5
1592    checkpoint52f_pre
1593    
1594    checkpoint52e_post
1595    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1596      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1597    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1598      to work with implicit vertical advection and AB ;
1599    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1600    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1601     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1602    checkpoint52e_pre
1603    
1604    o fix bug in impldiff when Nr=1 or Nr=2.
1605    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1606    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1607    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1608      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1609    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1610    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1611    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1612    
1613    checkpoint52d_post
1614    o re-tiled many expts to allow comparison in multi-processor mode
1615      - updated output accordingly
1616      - changed hs94.128x64x5 to use intial T from file rather than use the
1617        random number generator
1618    o add infrastructure in model routines for fizhi and gridalt packages
1619    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1620    o changes to permit hi-res, cubed-sphere, configuration
1621      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1622      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1623      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1624        of surface winds for the cube
1625      (A verification experiment, based on global_ocean.cs32x15, but with
1626       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1627       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1628       complete with example surface forcing files and matlab scripts to look
1629       at the output and compare it with that of global_ocean.cs32x15.)
1630    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1631       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1632       to conform to the common rule.
1633    o check-in the first version of the coupler + interfaces for multi-components
1634       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1635       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1636       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1637       - ocean and atmos. share the same horizontal grid (no interpolation).
1638       - exchanges between component and coupler is done in forward_step
1639    o new verification experiment, cpl_aim+ocn:
1640       coupled ocean - AIM atmosphere on cs32 grid.
1641    
1642    checkpoint52d_pre
1643    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1644    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1645    
1646    checkpoint52c_post
1647    o Fixing OPTIONS files for use of exf:
1648      - ALLOW_ECCO not needed
1649      - ECCO_CPPOPTIONS.h should not be included from
1650        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1651        as has been the case in the past
1652      - All cal/exf related options are currently set in
1653        single header file. Should remain so until we
1654        agree on a consistent new policy.
1655    o Removed all CPP options for cal package.
1656      cal has no more CPP options.
1657    o modified STOREs in GAD_ADVECTION
1658    o corrected key comp. for passkey
1659    
1660    checkpoint52b_post
1661    o new version: "thsice" of thermodynamic sea-ice pkg:
1662     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1663     - modify fluxes but do not change theta directly;
1664     - light cleaning of bulk_force pkg (still needed with thsice).
1665     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1666       + output_thsice.txt to test thsice & bulk_force pkgs.
1667    o put back grid & coriolis monitor output.
1668    checkpoint52b_pre
1669    
1670    o call "do_the_model_io" at the beginning (=> dump initial state)
1671    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1672    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1673      (need info on NUMBER_OF_PTRACERS)
1674    o missing PTRACERS headers in some routines
1675    o default tamc.h in pkg/autodiff supposed to crash
1676      to ensure proper customization
1677    
1678    checkpoint52a_post
1679    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1680      - moved surfaceTendencyTice from pkg/seaice to main code
1681      - subroutine FREEZE_SURFACE now limits only surface temperature
1682        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1683        => new output.txt for global_ocean.cs32x15 & global_with_exf
1684      - keep the old version of FREEZE for backward compatibility;
1685        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1686      - corresponding modifs for TAF directives
1687    o added surface flux output variables to TIMEAVE_STATVARS
1688    o time-averaged output for pkg/ptracers
1689    o fix problem with ECCO-related divided adjoint
1690      snapshot file was missing some ad-variables,
1691      but no warning issued by TAF
1692    
1693    checkpoint52a_pre
1694    o some bug fixes for #undef REAL4_IS_SLOW
1695    
1696    checkpoint52 = ecco_c52_e35
1697    o after testing adjoints of checkpoint51u_post
1698    
1699    checkpoint51u_post
1700    o this is the post-merge tag of the ecco-branch
1701      (needs another clean checkout and re-testing)
1702    o various natl_box_adjoint configs and results
1703      but no input fields
1704    o obcs adjoint not yet merged!
1705    o adding ECCO global 1x1 and 2x2 degree configs
1706    o updated/extended some store directives for seaice
1707    o pkg/ecco now containes ecco-specific part of cost function
1708    o top level routines the_main_loop, forward_step
1709      supersede those in model/src/
1710      previous input data.cost now in data.ecco
1711      (new namelist ecco_cost_nml)
1712    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1713    
1714    checkpoint51t_post
1715    o this is the pre-merge tag of the ecco-branch
1716    
1717    checkpoint51s_post
1718    o cleanup: removed various obsolete #define-s
1719    o pkg/grdchk
1720      - renamed 'ph-grd 3' to 'grad-res'
1721      - merged from ecco-branch
1722        (remaining bug fixes for obcs gradient checks)
1723      - additional high-precision output for testreport
1724        (grep for 'precision_grdchk_result')
1725    
1726    checkpoint51r_post
1727    o cleaned up or removed CPP_OPTIONS.h files
1728    o updated results for some of the tests to reflect the new
1729      optfiles (-ieee: -O0 instead of -O3)
1730    
1731    checkpoint51q_post
1732    o cd_code:
1733      - moved cd_scheme.F -> cd_code_scheme.F
1734      - separate read_checkpoint from cd_code_ini_vars.F
1735      - separated cd_code part from write_checkpoint
1736      - updated AD_SOURCE, generated .flow
1737      - added CD_CODE_VARS.h to the_main_loop
1738      - Moving cd_code specific store dir.s to pkg/cd_code
1739    o ctrl package totally restructured
1740      - pack/unpack now optional and decoupled from
1741        xx_/adxx_ I/O
1742      - ctrl_pack/unpack cleaned
1743        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1744      - confined inclusion of AD_CONFIG.h to where necessary.
1745    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1746    
1747    checkpoint51p_post
1748    o create initial cd_code package
1749      - WARNING: the initialization of fields within packages
1750        is broken because INI_FIELDS (where READ_CHECKPOINT is
1751        called) is called *before* PACKAGES_INIT_VARIABLES.
1752        This seems to be backwards since
1753        1) its important to initially zero the entire field including
1754           the "halo" region
1755        2) zeroing needs to be done *before* reading pickup info
1756           and the pickup call might or might not happen in any
1757           particular run
1758      - this needs an overhaul for R2
1759    o cleanup verification/*/code/GMREDI_OPTIONS.h
1760    o cleanup testreport
1761    
1762    checkpoint51o_post
1763    o bringing AD-related verif's up to date with genmake2
1764      - carbon/
1765      - global_ocean.90x40x15/
1766      - hs.94.1x64x5/
1767      - (front_relax/ )
1768    o (more) consistent directory structure for AD-related verif.'s
1769    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
1770    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1771    o bug fix in find_alpha.F for MDJWF:
1772      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1773        change rho -> rho-rhoConst
1774      - replace call find_rho to find_rhonum
1775    o initialisation of rFlx extended to full array (required by TAF)
1776      and shifted to thermodynamics
1777    o removed PTRACERS.h in ptracers routine
1778    o added surfacetendencyPtr to S/R parameter list pracers_forcing
1779    o Correcting initialisations for fVerU, fVerV.
1780    o helping TAF to recognize dependency on kUp for
1781      fVerU, fVerV
1782    o Replacing delZ by delR in pkg/ctrl/
1783    checkpoint51o_pre
1784    
1785    o undid all of cp51 pending some cleanups and discussion
1786    o added the [#include "AD_CONFIG.h"] statement to all files that need
1787       it for adjoint/tl #defines
1788     o re-worked the build logic in genmake2 to support AD_CONFIG.h
1789     o removed tools/genmake since it no longer works
1790    
1791    checkpoint51n_post
1792    o modifications to make FREEZE flux visible to pkg/kpp
1793      - moved surfaceTendencyTice from pkg/seaice to main code
1794      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1795      - subroutine FREEZE now limits only surface temperature
1796        (this means new output.txt for global_ocean.90x40x15,
1797         global_ocean.cs32x15, and global_with_exf)
1798    o added surface flux output variables to TIMEAVE_STATVARS
1799    
1800    checkpoint51n_pre
1801  o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F  o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
