4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o change default MAX_NO_THREADS from 32 to 4 ;
8      and stop cleanly when MAX_NO_THREADS is too small.
9    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
10    
11    checkpoint58m_post
12    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
13       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
14    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
15       keep global_ocean.90x40x15 (for AD testing) with former secondary test
16       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
17    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
18        add MITgcm_tutorials (= code + all the tutorials)
19    o ecco, option to compute cost for total ssh (mean+anom)
20    o consistent with addition of ptracer and ssh in pkg/profiles
21    o profiles: adding ptracer and ssh
22    o testreport: change multi-test output-file name
23      (from output.txt.{name} to output.{name}.txt)
24    o profiles: now ok for mutli-threaded case
25    o seaice: add 4 parameters for different advection schemes for area,
26      (effective) seaice thickness, enthalphy, and snow height. Their default
27      is the standard parameter SEAICEadvScheme
28    o calc_gw:
29     - add cosFacU in zonal viscous flux (harmonic.visc.).
30     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
31       of tutorial_plume_on_slope.
32    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
33    o calc_gw: true flux-form, account for horizontal grid spacing.
34      update rotating_tank results, but not plume_on_slope (affected at
35      truncation level, 11 digits).
36    
37    checkpoint58l_post
38    o calc_gw:
39     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
40     - remove side-drag for now (need to fix it); update plume_on_slope results.
41     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
42    o commit code to make SST/SSS weights spatially variable
43      (based on either variable in-situ or variable initial T/S weights)
44    o pkg/ecco:
45      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
46        now based on horizontally varying weights wthetaLev, wsaltLev
47      * cost_averagesflags now returns year indices in addition to day, month
48      * sflux balance is performed on annual basis
49        (sflxumm, sfluxmm2, bal_sfluxmm)
50      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
51        including separate counting and multipliers
52    o pkg/rbcs
53      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
54    
55    checkpoint58k_post
56    o testreport:
57     - always build in dir. "build" (if not there, mkdir build instead of building
58       & running in input)
59     - run in dir run (if it exists), in build otherwise.
60     - call prepare_run (if input/prepare_run exists)
61     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
62    o pkg/exf modifications to interpolation and rotation routines for more
63       reasonable treatment of North Pole singularity: for tracers North Pole
64       value is set to northernmost zonal-mean value, for zonal velocity it is
65       set to zero, and for meridional velocity it is set to northernmost value.
66    o pkg/exf/exf_check_range.F
67     - add tile index to diagnostics and move stop statement to the very
68       end of the routine.
69    o pkg/diagnostics: (diagnostics_main_init.F)
70      define title of isomorphic variables according to the current config.
71    o pkg/thsice with pkg/seaice dynamics:
72    - fix domain of computation (interior only, required for exf) and do exchanges
73    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
74    o towards a standard way of dealing with multi-threading in MONITOR
75      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
76    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
77       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
78    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
79    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
80    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
81       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
82    o tracer advection:
83     - clean-up and simplify calc_common_factors.F
84     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
85       advection subroutine (but still not used within DST advection S/R)
86    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
87    
88    checkpoint58j_post
89    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
90      from file (collects calls previously in FORWARD_STEP)
91    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
92    o adjoint store dir. adjusted accordingly
93    o genmake2
94      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
95    
96    checkpoint58i_post
97    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
98      on wind stress (SEAICEstressFactor defaults to 1.)
99    o Total number of Timers is finite (<=40): comment out 2 non-essential one
100      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
101    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
102      on CS-grid: no longer loosing mass.
103    o exf & curvilinear-grid: no longer modify longitude xC & xG.
104    o pkg/ggl90: fix sloppy output and fix a bug
105    o pkg/seaice: added SEAICEuseEVPpickup parameter
106      - Set to false in order to start EVP solver with
107        non-EVP pickup files when using SEAICEuseEVP
108      - fix sign error in diffusion in seaice_calc_rhs
109    
110    checkpoint58h_post
111    * Modifications for bottom topography control
112      o replace hFacC by _hFacC at various places
113      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
114      o add non-self-adjoint cg2d_nsa
115      o update autodiff support routines
116      o re-initialise hfac after ctrl_depth_ini
117      o works for 5x5 box, doesnt work for global_ocean.90x40x15
118    * Adding verification for 5x5 box (4-layer) bottom topography control
119    
120    checkpoint58g_post
121    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
122       used for mean seasonal cycle, mean diurnal cycle); add an example
123       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
124    o pkg/ggl90:
125      - add parameter (minimum surface kinetic energy)
126      - fix bug (avoiding division by zero)
127    o couple pkg/thsice to pkg/seaice:
128      - modify advection in seaice to accomodate new scalar fields to be advected
129      - only muliDimAdection scheme work with seaice/thsice
130      - mapping of thsice-variables to seaice-variables, back and forth
131      - does not break the verification experiments, but does not give the
132        desired results either
133    o pkg/seaice
134      - make (default) second order advection a bit less confusing?
135    
136    checkpoint58f_post
137    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
138      to pkg/seaice):
139      - new routines thsice_map_exf and thsice_get_exf provide the interface
140      - add an additional formal parameter to thsice_solve4temp
141    o pkg/exf:
142      - add new fields wspeed, snowprecip (to be able to couple to thsice)
143      - correct Stefan-Boltzmann constant
144      - new parameter for longwave surface emittance
145      - separate some stuff from exf_bulkformulae into new routines  
146        exf_radiation, exf_wind
147      - add new parameters and constants: longwave emissivity for ocean, ice
148        and snow, evaporation parameters over ice
149      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
150        either wind from stress or stress from wind
151    o pkg/thSIce:
152    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
153    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
154       and THSICE_CALC_THICKN
155    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
156    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
157      to make debugging easier.
158    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
159    o pkg/bulk_force:
160      - clean-up comments and parameters ;
161      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
162    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
163      generate new output for test-experiment: aim.5l_cs.thSI
164    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
165      testreport accordingly
166    
167    checkpoint58e_post
168    o SEAICE_CGRID adjoint done
169    o R_STAR adjoint implemented.
170      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
171      * need to sort out init. of h0facc, etc.
172    o Make pkg/profile fully independent of ecco,cost, etc. stuff
173      to be able to use it in pure forward.
174    
175    checkpoint58d_post
176    o upgrade simple test-experiment to tutorial example:
177     step.1: duplicate the experiment and (step.2) will remove the old copy.
178      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
179      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
180      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
181      tutorial_global_oce_biogeo    <- copy of dic_example
182      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
183      tutorial_plume_on_slope       <- copy of plume_on_slope
184      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
185      tutorial_global_oce_optim     <- empty for now (David ?)
186      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
187     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
188    o correct a sign problem in cost_scat.F
189    o obcs and ptracers: fix boundary conditions for advections schemes
190      with larger stencil
191    o thsice adjoint: start
192    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
193      completeness
194    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
195      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
196    o ptracers adjoint:
197      * avoid extensive recomputatations
198      * fix missing re-init. of gptr (missed by TAF)
199    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
200      me to turn off the excessive output to STDOUT that this package produces
201    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
202      and add those terms in Vector-Invariant formulation.
203    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
204      if the control period (xx_hfluxperiod etc) is 0
205    o in profiles pkg, clean routines and fix details
206    o in ecco pkg, reading ssh data:
207      fix problem in case the model does not start at iter0=0
208    o fix mnc-pickup/restart for ptracers
209    o new package prifiles:
210      code to compute profile-based cost by Gael Forget
211      (modifs in ecco, ctrl, autodiff)
212    o Benign bug fix in initialization (spotted by M. Mazloff) of
213      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
214    
215    checkpoint58c_post
216    o adjoint: finish NLFS adjoint and provide reference output in
217      verification/global_ocean.90x40x15/results_ad_nlfs
218    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
219      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
220      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
221      with SEAICE_CGRID defined.
222    o move calendarDumps from "data" to "data.cal" and clean-up the code
223      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
224    o add useEXF & useCAL flags (for now, set in hard-coded way)
225    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
226      (were missing in NH mode, and wrong in quasihydrostatic mode).
227      waiting for Chris updated version of calc_gw to add those CALLs.
228    o fix bug in quasihydrostatic S/R ;
229      add a test for this option: global_ocean.90x40x15.qshyd
230    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
231      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
232    o add on/off flag useOffLine for package OFFLINE
233    o seaice:
234      - modify advection so that it works also on the C-grid
235      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
236        problem in multi-tile runs with C-grid
237      - add flags for clipping ice velocities and/or masking solver forcing
238      - fix drag (ocean on ice) formulation and a bug that caused noise in the
239        C-grid solver
240      - added a few comments to seaice_diffusion.F
241      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
242        are now exclusive)
243      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
244        required re-ordering the code a little:
245       + make DAIRN global variable (defined in SEAICE)
246       + move computation of the viscosities eta and zeta into a new separate
247         routine (because I need to recompute them in seaice_ocean_stress.F)
248    
249    checkpoint58b_post
250    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
251      update output.txt of exp. aim.5l_cs.thSI
252    o various mnc cleanups and improvements:
253      + shrink lookup tables by factor of ~4
254      + better error reporting when running out of lookup space
255      + able to handle longer path/file names (up to 500 chars)
256    o adjoint:
257      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
258      - TBD: "hidden" mom_vecinv recomp. in dynamics
259    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
260     (allow to differentiate between forcing components using new integer flags:
261      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
262     and add new flag to put Dissipation tendency out of Adams-Bashforth.
263    o ecco
264      - enable trend removal from SSH anomaly obs.
265    o adjoint
266      - a fix for PmEpR when #undef EXACT_CONSERV
267      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
268      - try to fix "hidden" recomp. in forward_step for NLFS
269        (NLFS seems broken sometimes after I checked it in)
270    o seaice:
271     - add c-grid version of the dynamic solver:
272       + three new routines that are the c-grid substitute lsr, dynsolver
273         and ostres
274       + put a few fields that were local to dynsolver into global common
275         blocks, so that I can move the computation of stresses etc into
276         seaice_lsr (saves coding but may break the adjoint).
277     - replace more hardwired parameters by runtime parameters
278     - add ice masks that mask the rhs of the implicit solvers where there
279       is no ice (commented out in seaice_dynsolver, because i am not sure
280       if this works properly), eventually this should replace the clipping
281       of ice velocities in seaice_dynsolver to +/-40cm/s.
282    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
283      include it only where its needed
284    o move balancing of fluxes before the call of external_forcing_surf
285    o seaice:
286      - correct units of turning angles (now they are really in degrees)
287      - move computation of GWATX/Y out of main routine into dynsolver
288      - initialize GWATX/Y in seaice_init
289    o Apply mask on Fresh-Water flux (needed for SSH forcing).
290      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
291    o seaice: add runtime flags for turning angles (default to zero)
292    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
293      and trend from exf forcing and ctrl control adjustments
294    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
295      (since checkpoint57x_post)
296    o change the default rotation period to 86164.s = the Earth rotation
297    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
298      and based on a reference stratification. Tested within hs94.cs-32x32x5.
299    o seaice advection: add code for choosing between the default (2nd order
300      central differences) and multiDim advection schemes provided by
301      pkg/generic_advdiff
302    o seaice:
303      - removed all references to SEAICE_GRID.h fields from
304        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
305        (cubed-sphere configuration will change a little)
306      - grid computations in seaice_init are obsolete now.
307      - cleaned up code a little so that is easier to read (hopefully).
308      - added new (better?) discretizations of default advection and diffusion
309        (turn on with SEAICEuseFluxForm)
310      - replace 1 in 3d global fields by kSurface in growth.F
311      
312    checkpoint58a_post
313    o seaice:
314      - bug fix in advect.F
315    o shelfice:
316      - separate shelfice load anomaly from pload (breaks with time
317        dependent forcing), => introduce constant field shelficeLoadAnomaly.
318        Its default is 0., but it may be computed more cleverly from (unknown)
319        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
320        done offline. A good approximation of the pressure load anomaly is
321        necessary to avoid large initial adjustment processes underneath
322        deep-reaching shelfice.
323      - small fix in ISOMIP shelfice_thermodynamics
324      - add more sophisticated thermodynamics of Hellmer (1989), this is
325        now the default
326      - give a few constants more intuitive names
327    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
328      if bulk formulae are used in long integration (especially EmPmR). Turn
329      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
330      if balancePrintMean, the imbalance that is substracted is printed to
331      STDOUT.
332    o fix bug (typo) in obcs_apply_eta.F
333    o add a new package shelfice which enables us to model the circulation
334      underneath shelf-ice with draughts of hundreds of meters.
335     - works
336     - to do: + include improved thermodynamics
337              + check whether kSurfC (from model/inc/SURFACE.h) can be used
338                instead of new field kTopC
339              + can we use topoFile, Ro_surf and existing code in ini_depth.F
340                instead of new field R_shelfIce and new code in ini_depth.F
341                and ini_mask_etc.F?
342              + adjust vertical mixing schemes?
343    o seaice pkg:
344     - add a cpp-flag to include a simple formula for a salinity dependent
345       freezing point of sea water at the surface
346     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
347       meridional stresses are now different (and hopefully correct)
348    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
349       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
350       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
351    o pkg/diagnostics: add options and parameters for regional-statistics
352       diagnostics ; define regions by reading a region-mask from a file
353       (might add other options later)
354    o pkg/bulk_force:
355     - add option and parameters to use AIM surface-flux formulae.
356     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
357       others forcing fields (defined in PARM05, parameter file "data") are loaded
358       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
359     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
360     - use the right EXCH call for uwind,vwind (to work on CS-grid).
361     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
362       and parameters (note: calcWindStress replaces .NOT.readwindstress).
363     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
364    
365    checkpoint58
366    o add "--embed-source" option to genmake2 which, when the supporting
367      tools can be compiled (as determined by genmake2) will turn on the
368      embed_files package which then embeds the entire MITgcm source code
369      (*.[fFhc] + Makefile) used for the build within the executable
370      - requested by CNH but off by default
371      - adds a paltry <9MB to the mitgcmuv executable in most cases
372      - only writes the output when useEMBEDSRC in eedata is true
373    o clean up 3-dim. relaxation codes:
374      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
375      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
376      * Thanks to Tom Haine for testing!
377    
378    checkpoint57z_post
379    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
380      affects output (@ truncation level) of exp. plume_on_slope ; updated.
381    o fix the pickup behavior for obcs in combination with ptracers
382    o fix a bug in ptracers_external_fields_load
383    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
384      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
385    o transfered surface NH pressure to eta field (if exactConserv).
386    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
387         and update lab_sea output.txt file.
388    o completing 3-dim. relaxation code: additional term
389         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
390      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
391      * At compile time, in "EXF_OPTIONS.h" set
392          #define  ALLOW_CLIMTEMP_RELAXATION
393          #define  ALLOW_CLIMSALT_RELAXATION
394      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
395          tauThetaClimRelax3Dim = 15552000.0,
396          tauSaltClimRelax3Dim  = 15552000.0,
397      * 3 cases:
398          1) Use a constant-in-time 3-dim. field
399          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
400          3) Real-time relax. to time-evolving prescribed field
401    o Adding Laplacian-type smoothness constraint on
402      initial and boundary (forcing) controls (ic, bc)
403      * enable at compile-time via
404        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
405      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
406      * Absolute scale somewhat unclear so far
407      * no area weighting was included since no other cost term does so far
408    
409    checkpoint57y_post
410    First step for a NLFS adjoint
411    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
412    o new init. routines for calc_r_star, calc_surf_dr
413    o still need to deal with ini_masks_etc
414    o testreport seemed happy
415    checkpoint57y_pre
416    
417    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
418    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
419    o add new offset feature to offline pkg (plus minor cleanup)
420    o cfc fixes for final year of integration
421    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
422      be in GCHEM_OPTIONS).
423    
424    checkpoint57x_post
425    o fix testreport Pb in multiple test experiment.
426    o cleanup our namelist syntax in verification:
427      - make it more F95 standards compliant (some work still needed)
428      - allows the vast majority of our tests to work with gfortran
429    o Non-Hydrostatic:
430     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
431     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
432    o Allow to apply AB on T,S rather than on AB(gT,gS):
433     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
434     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
435       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
436     - need a "clever" read_pickup to restart from the other AB formulation
437    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
438    o remove some unused variables (reduces number of compiler warnings)
439    o adjoint
440      * Disable useVariableViscosity for adjoint for time being
441        (there are a number of extensive recomputations)
442      * Initialize certain variables needed for adjoint
443    
444    checkpoint57w_post
445    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
446                 fix the singleCpuIO RS version of MDSWRITEFIELD
447       and add a WARNING if using globalFiles=T with multi-processors.
448    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
449      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
450    o tracer advection scheme:
451      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
452       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
453       was not very convenient).
454      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
455       (further tests needed for the implicit DST & Flux-Limiter schemes).
456    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
457      and sRef for convenience, handy, when you want to initialize
458      ptracers in a large domain with a constant non-zero value. Also,
459      untangle ptracers_init.F a little.
460    
461    checkpoint57v_post
462    o change dome exp. to use variable viscosity in side-drag terms.
463    o remove all the files from the cfc_offline test since they are now
464      incorporated into tutorial_cfc_offline which has been producing
465      identical results for a few days of testing
466    o add new parameter: sideDragFactor to enable half-slip-side BC
467      and change side-drag S/R to use viscosity from mom_calc_visc
468      (can switch back by setting sideDragFactor=0.); affects results at
469      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
470       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
471    o vorticity & strain are now computed without masking, to account for
472      no-slip-side BC in variable viscosity calculation ; mask is applied
473      anyway later on, before computing advection/coriolis terms.
474    o modify exp4 to test new obcs support for reading from external files
475      and for passive tracers
476    o fix behavior of ptracers_monitor when monitor output is written to a
477      netcdf-file; still not independent of monitor.F (writes in the same
478      file).
479    o change default value of tRef (put a uniform, meaningful value for ocean
480      & atmos) and initialize sRef (was missing, as Martin mentioned).
481    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
482      to be proportional to enstrophy dissipation length.  Thus,
483       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
484      This is now consistent with Smagorinsky and with the manual.
485    
486    checkpoint57u_post
487    o OBCS and PTRACERS: add open boundary support for passive tracers
488      - either use homogenous (pseudo) v.Neumann conditions or prescribe
489        OB-values from file; this is not different from the way theta and salinity
490        are treated
491      - however, Orlanski-radiation conditions are not supported, and the model
492        will stop if you use pTracers and Orlanski at the same time.
493      - beefed up the rountine obcs_external_fields_load: now only those open
494        boundary values are overwritten with values from files for which there
495        are really files, otherwise the OB-fields remain untouched. This makes
496        it possible to use different OBs at different ends of the domain (as
497        with EXF)
498    o reduce number of exch calls in shap_filt (s2).
499    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
500      truncation level) 4/5 MLAdjust test results (11&12 digits match).
501    
502    checkpoint57t_post
503    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
504    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
505      same truncation, independent of the face number: affects affects several
506      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
507    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
508      note that biharmonic viscosity + no-slip was not tested in any experiment.
509    o fix bug in non-linear free-surf side-drag ; generate new output for
510      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
511    o make mnc honor the writeBinaryPrec flag for most kinds of output
512    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
513    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
514      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
515    o add brackets in multi-terms sum to get same truncation, independent of
516      the face number (manage to get exactly same value of gU,gV at the cs-edge)
517      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
518    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
519      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
520      a maximum grid-scale Reynolds number.  Also, changes all length calculations
521      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
522      Suggested values of viscosity parameters found in mom_calc_visc.
523      Many new viscosity diagnostics available.
524    
525    checkpoint57s_post
526    o Add clearing-house for viscosity calculations, mom_calc_visc and
527      correct numerous bugs in LeithD and Smagorinsky discretizations.  
528      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
529      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
530      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
531      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
532      The Strain-Tension form is now called with useStrainTensonVisc=.true.
533      ViscAhStrain and viscAhTension are now retired.
534    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
535    o In response to JMC's bug report, genmake2 now ignores any soft-links
536      that it finds in the *current* directory when searching for files.
537      Soft-links found in any other source directories will still work as
538      they did before.
539    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
540      a C routine to unlimit the stack size
541    o mnc-ify pkg/aim snapshot vars
542    o mnc-ify pkg/land as requested by Daniel
543    o various changes to mnc including:
544      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
545      - output can now be grouped so that all files within a group
546          change the ITER portion of their names in lock-step together
547      - can now read ("global") PER-FACE (in addition to PER-TILE) files
548          and works with both EXCH1 and EXCH2 (but needs more testing)
549      - writing works for all verification test cases w/ g77 on Linux
550    
551    checkpoint57r_post
552    o make MNC variable initialization happen earlier
553    o add diagnostics for (almost) each term of the momentum Eq.
554    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
555    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
556    o remove MINIMAL_TAVE_OUTPUT option ;
557      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
558    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
559      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
560    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
561    o add time-dependent SST, SSS control
562    o cost terms in ecco/ modularized (new cost_generic.F)
563    o cost_averages routines are modularized (new cost_averagesgeneric.F)
564    o new infrastructure for seaice model vs. obs misfits in seaice/
565      * driver from the_main_loop.F is seaice_cost_driver.F
566      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
567      * gradient check in Exp. 6a of natl_box_adjoint/
568    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
569      (see README file)
570    
571    checkpoint57q_post
572    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
573    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
574      - bug was reported by Jean-Michel and Ian Fenty
575    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
576      update exp. cpl_aim+ocn output.
577    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
578      Needed for high-res. runs with large global files
579      to be able to limit tapelev size
580    o Changed some tests for adjoint:
581      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
582      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
583      * global_ocean.90x40x15/ back to default 3-level checkpointing
584    o Modifications to enable scripted COMMON to MODULE conversion
585      * verification/OpenAD/code/ has necessary scripts and description;
586      * converts, compiles and runs successfully;
587    
588    checkpoint57p_post
589    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
590    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
591      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
592    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
593    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
594      (was already the case for dissipation with mom_vecinv,
595       and also the case for grad.PhiHyd when staggered-timeStep)
596      This will allow to put dissipation out-off the AB time-stepping.
597     Unfortunately, affects truncation error. Update output of exp. that "fails"
598      (cg2d matching number) and leave the others for later: front_relax(10),
599      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
600      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
601    
602    checkpoint57o_post
603    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
604      (2) its ready to be documented during the 20050801 DocFest
605    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
606      for ideal_2D_oce and lab_sea on linux_ia32_g77
607    o set to #undef CTRL_SET_OLD_MAXCVARS_30
608      in global1x1_tot/code_seaice_adj to access indices 32, 33
609      (worth another tag)
610    
611    checkpoint57n_post
612    o adding precip control xx_precip 32
613    o adding swflux control xx_swflux 33
614    o Replacing 10 forcing penalty cost routines by 1 generic.
615    o Implementing partitioning in time-mean and variable adjustment
616      for atmos. state.
617    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
618    o in natl_box_adjoint:
619      * updated exp 1 to 10
620        (but does not have time-mean vs. variable split results yet)
621    o updated global1x1/*_seaice_adj/
622      to incorporate latest changes
623    o enable useSingleCpuIO for mdsio vector routines
624      (applies in particular to tapelev I/O)
625    o removed inefficient K-loop in all active_file*control*.F
626    
627    checkpoint57m_post
628    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
629      and advect_cs (use EXCH-2 and standard cs-32 grid files).
630    o pkg/exch2: filling of face-corner halo regions is optional
631      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
632    
633    checkpoint57l_post
634     tag before updating tutorials (pre-release-2)
635    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
636       for output and interpolation of input fields onto model grid)
637    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
638       Affects results of exp. rotating_tank ; update output.txt.
639    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
640          and taking the square quantity and/or using a fraction-weight field.
641    o fix aim_diagnostics_init.F mate numbers.
642    o add mnc output capability to diagnostics/diagstat and update
643      our cvsignore files for the ACSII output generated
644    
645    checkpoint57k_post
646    o lab_sea now uses diagnostics package and provides a suite of
647      new EXF diagnostics output.
648    
649    checkpoint57j_post
650    o exf
651      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
652        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
653        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
654      * extended diagnostics output
655        - now includes all EXF variables
656        - hs, hl moved to common block
657        - separate S/R for diagnostics, called after ctrl vector is added
658        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
659        - EXFqnet contains true Qnet (i.e. includes qsw)
660      * updated verif. lab_sea, global_with_exf
661      * Rearranging hflux (exf_mapfields -> exf_getforcing)
662        to ensure that diagnostics sees a true EXFqnet
663    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
664    o diagnostics pkg: change pointers so that 1 diagnostic can be used
665      several times with different frequencies.
666    o mnc-ify the thsice package as requested by Daniel Enderton
667      - the monitor--MNC output needs work
668      - many attributes need to be added (most are currently blank)
669    o mnc-ify theaim_v23 package as requested by Daniel Enderton
670      - many attributes need to be added (most are currently blank)
671    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
672    o add Sadourny like discretization to the 4th.O vorticity advection scheme
673    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
674      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
675         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
676    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
677     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
678    
679    checkpoint57i_post
680    o Diagnostics package was changed: diagnostic allocation is now deactivated
681      by setting an empty file name in the namelist (used to be by setting 0 frequency)
682    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
683      add 1rst Order upwind vertical Shear.
684    o add a quick fix for A/B checkpointing in OFFLINE mode
685    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
686      end-run around the C/Fortran linking horror in eesup/src/timers.F
687    o added pkg/runclock: allows user to terminate run based on wall clock
688    o added non-hydrostatic scaling parameter: nh_am2
689    o pkg/my82: futile attempt to make results compiler-independent by adding
690      some "_d 0", etc. no effect.
691    o for mnc output, fill the 'T' coordinate var with myTime and create a
692      separate 'iter' variable for iteration count
693    o pkg/diagnostics:
694      add new capability: output of Global/Regional & per-level statistics ;
695      tested against monitor output (including land & thSIce) on various exp.
696    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
697    
698    checkpoint57h_done
699      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
700      data.diagnostics, data.gchem, data.ptracers) is done.
701    
702    o pkg/diagnostics: prepare for Global/Regional statistics.
703      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
704    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
705      and rename it: DIFFERENT_MULTIPLE
706    
707    checkpoint57h_post
708    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
709    o pkg/diagnostics: change output frequency, now in seconds (instead
710      of Nb of iterations). This requires to change data.diagnostics.
711    checkpoint57h_pre
712    
713    o in mnc, let the user create the output dir if both mnc_outdir_date
714      and mnc_outdir_num are false
715    o add fflags() to pkg/diagnostics which allows one to specify, on a
716      per-file basis, the file precision [default behavior is unchanged]
717    o added diagnostics to pkg/kpp, including computation of mixed layer
718      depth based on a temperature/density criterion
719    o updated verification/natl_box to test the new pkg/kpp diagnostics
720    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
721    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
722    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
723      not mnc -- this mistake was found by JMC and is now corrected
724    
725    checkpoint57g_post
726    o add Adams-Bashforth 3rd Order time stepping:
727      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
728      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
729    checkpoint57g_pre
730    
731    o make lambda[Theta,Salt]ClimRelax spatially varying
732      (default remains spatially uniform constant based on tau)
733    o added new control variables
734      * init. uVel, vVel, etanN
735      * lambda[Theta,Salt]ClimRelax
736    o separate masks used for ctrl_pack/unpack 'from write_grid' output
737      (suggested by G. Forget)
738    
739    checkpoint57f_post
740    o add parameter "baseTime" = model base time = time at iteration zero
741      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
742      account for baseTime shift
743    o move Coriolis arrays from PARAMS.h to GRID.h
744    checkpoint57f_pre
745    
746    o mnc-ifying the seaice package
747    o introduced an alternative length scale calculation for use in the limiting
748      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
749    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
750    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
751      as well as grad(vort3).  Made it compatible with both approximate form
752      for the cubed sphere and full form of these gradients.  Added flag
753      useFullLeith to select between approximate and full form.  
754    o add "d0" in getcon.F to reduce differences between compilers/platforms
755      update output.txt of exp. fizhi-gridalt-hs
756    o change port_rand funtion to allow to set the seed.
757    o fix obscure MNC bug involving conversion between reals and integers
758      - it caused no problems with certain (eg. gcc, ifc) compilers but the
759        new version is now more standards-compliant
760    o adjoint-related modifications
761      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
762      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
763      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
764    
765    checkpoint57e_post
766    o Adding eddy stress controls a la Ferreira et al.
767    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
768    
769    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
770      update output.txt of exp. fizhi-gridalt-hs
771    o add more "Z" dimensions and associated coordinate vars to MNC
772    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
773    o parameter calendarDumps: when set, approximate months (30-31 days) and years
774      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
775      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
776      months and years.  Requires pkg/cal.
777    o diagnostics: add pickup functionality
778      - off by default for backwards compatibility
779      - current version only uses MDSIO -- MNC will be added
780    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
781    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
782    
783    checkpoint57d_post
784    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
785    o modify verification/ideal_2D_oce so that it tests the creation of mnc
786      output from the diagnostics package
787    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
788    o make genmake2 more portable by using ".$FS" instead of ".f" for more
789      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
790    o add coordinate variables to the MNC output from the diagnostics package
791    o change MNC-flags default value: true when useMNC=TRUE
792    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
793      the ability (off by default) to read the grid information using MNC
794    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
795    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
796    o do snap-shot diagnostics at the middle of the time-interval (instead of
797      at the end).
798    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
799      new test for AIM with thSIce + slab-ocean
800    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
801    o move state variable diagnostics to the beginning of the time step ;
802      (note: still needs some work specially for snap-shot diagnostics)
803      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
804    
805    checkpoint57c_post
806    o Change testing option (-ieee) to get closer agreement between g77 & ifort
807    o generate new output.txt files on faulks with g77 & the new -ieee option
808    checkpoint57c_pre
809    
810    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
811      update output.txt of exp. global_ocean.90x40x15
812    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
813      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
814    o add saltFlux(+File) forcing capability with periodicExternalForcing
815    o allow to use pkg diagnostics for GM-Redi & ThSIce output
816    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
817    o improvements for the MNC output from DIAGNOSTICS:
818      - correct handling of the unlimitied dimension
819      - all dims now have associated coordinate variables
820      - variables located at U, V, and Corner ("Z") points are now written
821        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
822        *all* data points are output
823    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
824    o added pkg/seaice/seaice_monitor.F
825    o mdsio_readfield.F can now read files visible only to master MPI process.
826    o pkg/seaice: some test code for ice-modified ocean stress
827    o exf_getffields interpolation defaults to bilinear for all scalar forcing
828      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
829      spurious negative numbers for precipitation and humidity.  Will cause
830      some small numerical differences for integrations using pkg/exf/exf_interp.F.
831    o pkg/ctrl/
832      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
833        May be enabled via doPackDiag
834      *  introduce z-scaling of
835         + gradient (doZscalePack) and
836         + control (doZscaleUnpack)
837    o pkg/mdsio/
838      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
839      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
840    
841    checkpoint57b_post
842    o simplify options in diagnostics_fill arguments (remove weird combinations)
843    o fix MNC coordinate variables so that they now contain per-face index
844      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
845      general, EXCH2 grids are only aligned to a "local" coordinate system
846    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
847    o Implement instantaneous output within pkg diagnostics:
848      setting a negative frequency in data.diagnostics produces
849     "snap-shot" output (as opposed to time-average if freq > 0)
850    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
851      NOTE: change ptracer diagnostics name: use 2 characters to work with
852            more than 9 tracers. Add also diagnostics of advect & diffus flux.
853    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
854      becomes the coordinate variable for the 'T' dimension
855    o add CF-style coordinate variables to MNC
856      - just a first cut:  numbers are meaningless on the cubesphere and
857        missing along the T axis but otherwise it works!
858    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
859    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
860    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
861      this is based directly on what the model compute, so that the content of
862      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
863    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
864    o clean up build options files for SunOS, in particular
865      - remove -traditional from xmakedepend
866      - change -xarch=v9 to -xarch=native for f77
867      - restore use of make (not gmake)
868      - add CC=gcc if using g77
869    o changes per discussion of AM, JMC, & EH3 today:
870      - move redundant "grid" variables out of "state" -- in preparation of
871        creating proper CF-style coordinate variables and in recognition
872        that any/all grid variables can be easily copied (eg. w/NCO) from
873        the grid files into any of the other NetCDF files
874      - *always* output grid variables with MDSIO (this will eventually be
875        changed)
876      - output MNC grid file if useMNC is true
877    o every instance of _END_MASTER() has been found and replaced with
878      _END_MASTER( myThid ) in order to satisfy certain picky Sun
879      preprocessors
880    o re-arrange diagnostics pkg initialisation:
881     - allow each package to extend the available diagnostics list
882     - add some checking and fix small problems (multi-threaded, ...)
883     - new S/R diagnostics_fill (replace fill_diagnostics):
884       look through the short list of active diag. (instead of the long list)
885       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
886    
887    checkpoint57a_post
888    o this set of changes restores TAMC compatibility
889      tested for global_ocean.90x40x15 adjoint on trough
890      (what a pain)
891    
892    checkpoint57a_pre
893    o some modifs in tools/build_options for sunos
894    o call ctrl_pack for ctrl at end for optimcycle=0
895    
896    checkpoint57
897    o add horizontal bi-harmonic viscosity for vertical velocity
898      - new parameter viscA4W (defaults to viscA4)
899      - affects only non-hydrostatic code
900      - to be done: no-slip lateral boundary conditions
901    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
902    o implement Implicit Vertical advection for pTracers
903    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
904      (implemented also for implicit vertical diffusion & advection)
905    o OBCS: extend application of tracer open boundary conditions
906      to a strip beyond the boundary of width Olx/Oly
907    o add call monitor to TAF set of required calls (flow directives)
908      and include in natl_box_adjoint
909    o untangle a few ifdefs related to cost, ctrl, autodiff
910      untangel a few ALLOW_ECCO_OPTIMIZATION
911    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
912      (theta2, salt2 in ecco_cost_weights)
913    
914    checkpoint56c_post
915    o OBCS as control variables
916      - update ctrl_ad_diff.list, obcs_ad_diff.list
917      - remove balance of obcs controls from default
918      - fix index bug nobcs in ctrl_init
919      - fix dummy fields filen in ctrl_pack
920      - add dummy weights for obcs
921    o lsopt: comment out fort.94 output
922    o optim:
923      - remove unnecessary header files
924      - adjusted namelists
925      - add xerbla.F to Makefile
926    o exf:
927      - multiple modifications of exf_check_range
928      - unit change in exf_init_runoff from [m/year] to [m/s]
929    o mdsio:
930      - i/o-vector change debugLevel from debLevA to debLevB
931    
932    checkpoint56b_post
933    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
934      is called from DO_THE_MODEL_IO
935      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
936      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
937      - clean up PTRACERS_WRITE_TIMEAVE a little
938    o add another verification experiment that tests both the cfc-pkg and
939      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
940      reactive tendencies treated inline with regular timestepping
941    o testreport previously did a lousy job of comparing small numbers, so
942      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
943      implemented in the little c-progam tmp_cmpnum.c which is embedded in
944      testreport.
945    o ptracers_monitor: bug fix for MPI
946    
947    checkpoint56a_post
948    o GCHEM: finish reorganizating the package
949      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
950        (introduces another 3D-array for each passive tracer, but only if
951        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
952        gchemTendency is not needed because the timestep is done separately)
953      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
954      - GCHEM is now---more or less cleanly---separate from PTRACERS
955      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
956        so clear to me how that should be done in a general way.
957    o CFC: improve formatting of output in CFC_ATMOS
958    o PTRACERS:
959      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
960        that ALL experiments with ptracers enable can be checked. This makes
961        GCHEM_MONITOR obsolete.
962      - include a runtime parameter PTRACERS_monitorFreq that defaults to
963        monitorFreq
964      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
965    o add PTRACERS (PTR0[1-5]) to testreport output
966    o exf_check_range:
967      * default changed to .TRUE.
968      * will check values for niter0 if debLevA, every timestep if debLevB
969      * STOP in exf_check_range if 'out of range'
970      * range chosen generous to allow for potential extema
971      TBD: a version with stricter range
972           permitted range would be runtime parameters
973    o GMredi:
974      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
975      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
976      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
977    o GCHEM:
978      - move call to GCHEM_FORCING_SEP, so that it is now called before
979        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
980      - introduced a useGCHEM runtime flag and applied it everywhere.
981      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
982        this flag is now only visible within GCHEM-pkg routines.
983      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
984        be replaced by a 3D array that is computed before thermodynamics; for
985        this, the tracer ID iTracer had to be included into the parameter list
986        of ptracers_forcing
987      - set up forward_step to call gchem_forcing, that will replace
988        gchem_forcing_int in ptracers_forcing
989      - cleaning up
990    o small cleaning of exch2: remove files that are also in eesupp/src
991    
992    checkpoint56
993    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
994    o mnc: cleanup "full" files--fixes out-of-memory problem
995    o ECCO-GODAE
996      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
997      * fully merged and updated from SIO code
998        windstress sign change affects
999        - exf_inscal_[u/v]stress
1000        - sign of xx_tau[u/v] adjustments
1001        - signs in cost_scat
1002      * ctrl_get_gen: avoid update of tau[u/v] for first few days
1003      * natl_box_adjoint updated and compressed
1004      * 2-level checkpoint switch added
1005        (tested in EXP. 1 of natl_box_adjoint)
1006      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
1007    o SVD
1008      * first complete, non-hacked version for SVD calculations
1009      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
1010        performed via direct access files admtlm_vector.it????
1011        (via ctrl_[un]pack)
1012      * optimcycle is used for ARPACK iteration counter
1013        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
1014      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
1015        and add linear transforms where necessary
1016      * controls are initial/final SST, SSS (can be extended; need to check
1017        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
1018    o mdsio: filename info to both stderr, stdout
1019    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
1020      from sign change
1021    
1022    checkpoint55j_post
1023    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
1024      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1025    o add consistent build directories and .cvsignore files to verification
1026    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
1027    o make all subroutines 30 or less characters in length for certain older
1028      compilers to work (a thorough search only turns up two routines in
1029      pkg/ptracers)
1030    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
1031      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1032    
1033    checkpoint55i_post
1034    o change arrays for total vertical diffusivity (2.D if explicit,
1035      3.D if implicit) ; each ptracer uses its own background value.
1036    o added mnc/NetCDF output capability to ocn_compon_interf
1037      - added bits to verification/cpl_aim+ocn so that it can run on
1038        ITRDA and other clusters without the mpirun "-wd" option
1039    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
1040      configuration
1041    o give MNC the ability to create additional files rather than
1042      exceeding a specified file size limit "MNC_MAX_FILESIZE"
1043      - the default is just less than 2GB which is a practical limit
1044        on many systems
1045    o Compute the non-local term using either KPP vertical diffusivity (=default)
1046       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
1047    
1048    checkpoint55h_post
1049    o add verification test "vermix"
1050    o remove all the *_ioinc flags and replace with the single global
1051      outputTypesInclusive flag
1052    o allow to set a vertical profile of vertical diffusivity for T & S
1053    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
1054    o useMNC moved from data.mnc to data.pkg
1055    
1056    checkpoint55g_post
1057    o Renaming carbon AD experiments to comply with testreport conventions
1058    o Updating adjoint of Held-Suarez hs94.1x64x5
1059    o Fixing directives for non-ECCO forward_step, after ECCO directives
1060      have been fixed to avoid recomp. of do_oceanic_phys
1061      Works well for global_ocean.90x40x15,
1062      but recomp. issue remains for carbon
1063    o Updating adjoint output for natl_box_adjoint after
1064      pkg/ecco has been modified (see taga c55d_post)
1065    
1066    checkpoint55f_post
1067    o rename to timeave_init_fixed
1068    
1069    checkpoint55e_post
1070    o some delicate re-shuffle of store directives to avoid one
1071      extra call of do_oceanic_physics
1072      affects ecco_the_main_loop.F, do_oceanic_physics.F
1073      checkpoint_lev1_directives.h
1074    o NB: this may break global_ocean adjoint temporarily,
1075      but it is clear how to fix it. Will do later, need this now.
1076    
1077    checkpoint55d_post
1078    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1079    o ecco_cost_weights is modified to 1x1 runs
1080    o modifs to allow observations to be read in as
1081      single file or yearly files
1082    o enable to read exf forcing fields as either
1083      single file or yearly files (flag useExfYearlyFields)
1084    checkpoint55d_pre
1085    
1086    o switch between 2-level and 3-level checkpointing
1087    o add ability of MNC to write local and "partial" (eg. 2D slices where
1088      the full 3D field is never actually stored) arrays to NetCDF files
1089      with the correct (that is, the complete multi-dimensional) set of
1090      array indicies
1091      - used in mom_vecinv() to write the diagFreq output
1092      - tested (demonstrated) in verification/aim.5l_cs
1093    o further mnc-ification
1094      - add verification/lab_sea to the list with mnc setups
1095      - fix undefined mnc v-names in cd_code
1096      - add kpp to mnc output (both snapshot and timeave)
1097    o non-hydrostatic code
1098      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1099        in calc_gw.F
1100      - defaults to viscAh
1101      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1102        friction or Leith) in non-hydrostatic mode, as long as there is
1103        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1104    o pkg/cost
1105      extend simple cost functions to treat time mean quantities
1106      (T,U,V) via cost_accumulate_state from cost_tile
1107    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1108        be 2 times larger than the minimum size the advection scheme requires.
1109        now get a perfect conservation of salt in advect_cs test-exp (updated)
1110    o GGL90 (Gaspar's TKE mixed layer)
1111      - add horizontal diffusion of TKE, requires exchanges in
1112        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1113        default. In OPA there is no horizontal diffusion of TKE but the
1114        mixing coefficients are computed from a horizontal average of TKE of
1115        6 points or so. I think that diffusion has a little more physical
1116        justification.
1117      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1118        was in vain)
1119      - mask tke-variable in ggl90_init
1120    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1121    o fix biharmonic diffusion on CS-grid.
1122    o more obcs stuff
1123      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1124        for reading boundary values. This routine is called from
1125        obcs_prescribe_read
1126      - updated obcs_check
1127      - changed sponge layer relaxation parameter units for days to seconds
1128      - turned off sponge layer by default
1129      - changed argument list of OBCS_CALC to myTime+deltaTclock
1130      - fixed about 35 bugs in obcs_external_fields_load
1131    
1132    checkpoint55c_post
1133    o obcs stuff
1134      - new runtime flags useOBCSprescribe, useOBCSbalance
1135      - re-arranged obcs_calc
1136      - moved exf_getobcs to obcs_prescibe_read
1137        obcs_prescibe_read is called after ORLANSKI stuff
1138        and independent of it (executable can contain all).
1139      - updated obcs_check
1140      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1141        These may be necessary only if tangential velocities are
1142        prescribed at OB, not sure, needs testing.
1143    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1144      which simplifies the calls and passes the ifc check-bounds test
1145    
1146    checkpoint55b_post
1147    o add a 2D scalar, Z location, exchange_2 routine.
1148    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1149      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1150      affects advect_cs results (for the wrong reason): update output.txt
1151    o use a more standard discretization for biharmonic viscosity ;
1152     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1153      affects results of dome set-up: update output.txt
1154    o fix gad_advection.F (CubedSphere part), back to version 1.23
1155    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1156    
1157    checkpoint55a_post
1158    o merged code to
1159      * prescribe/read time-dependent open boundaries
1160        (works in conjunction with exf, cal)
1161      * sponge layer code for open boundaries
1162      * each boundary N/S/E/W now has its own CPP option
1163        (healthy for the adjoint)
1164    
1165    checkpoint55
1166    o up-to-date adjoint of previous breaks
1167      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1168      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1169      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1170      - carbon: * remove tr1-related adjoint verification
1171                * add ptracer as control variable
1172    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1173      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1174    
1175    checkpoint54f_post
1176    o in verification/carbin/ remove experiment related to
1177      ALLOW_PASSIVE_TRACER (array tr1 etc)
1178      code_ad/ input_ad/ results_ad
1179    
1180    o add two new packages
1181      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1182        + subject to optimization (memory)
1183      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1184        + subject to reordering (many GOTOs in the original code)
1185        + so far opps is called for every (i,j) point, and then operates in
1186          the vertical; one may want to reorder the scheme in order operate in
1187          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1188          fields)
1189    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1190      - all verification tests compile and run with linux_ia32_g77
1191      - defaults are compatible with current input files--nothing
1192        should change if you were not previously using MNC
1193      - MNC output has been added in numerous places (eg. timeave)
1194        but there are still a few writes not yet do-able with MNC
1195        (this is in progress)
1196      - flags now allow for either/or/both use of MDSIO and MNC and
1197        documentation will soon follow
1198      - numerous small formatting cleanups for ProTeX
1199    o add version info (via BUILD_INFO.h) to MNC and stdout
1200    
1201    checkpoint54e_post
1202    o add two new packages
1203      - pp81 (Packanowski and Philander, 1981), Richardson number and
1204        stratification dependent mixing
1205      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1206      - these scheme operate in a similar manner as KPP (without ghat, of
1207        course), however there is only one diffusivity that is used for both
1208        temperature and salinity (and passive tracers)ç
1209    o add offline package
1210    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1211      provided by Stephanie Dutkiewicz
1212    o genmake2: add ability to search for C compilers and cleanup test output
1213      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1214    
1215    checkpoint54d_post
1216    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1217    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1218      leading to additional shift by 5 days each year of integration
1219       (i.e. leading to considerable offset over the years)
1220    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1221    o start with no AB and no initial filtering (staggerTimeStep):
1222      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1223    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1224      (external loading & cpl import/export stay in forward_step.F)
1225    o update coupling interface to work with new staggerTimeStep
1226    o change MDSIO ptracers_pickup.
1227    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1228    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1229    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1230    
1231    checkpoint54c_post
1232    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1233      this affects (truncation error) output.txt of test-exp:
1234       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1235    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1236    o change Qnet to always be the net heat flux, (+upward).
1237      affects (truncation error) output of natl_box exp.: updated
1238    o define the max number of passive tracers in PTRACERS_SIZE.h
1239    o start to test mnc routinely in exp0
1240    o add sea-ice loading (sIceLoad) as a new forcing field.
1241    
1242    checkpoint54b_post
1243    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1244       impressive on Altix and Opteron systems)
1245    o diagnostics can now write NetCDF files through the mnc package
1246    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1247    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1248    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1249      affects (truncation error) output of lab_sea & natl_box exp.: updated
1250    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1251    
1252    checkpoint54a_post
1253    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1254    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1255    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1256    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1257      + internal_wave (shift in writing cg2d_ini_res)
1258    checkpoint54a_pre
1259    
1260    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1261      - modified verification/lab_sea and natl_box_adjoint accordingly
1262    
1263    checkpoint54
1264    checkpoint53g_post
1265    o prepare splitting of thermodynamics: store convect.counter in common block
1266    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1267      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1268    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1269    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1270    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1271    o restore adjointability
1272    
1273    checkpoint53f_post
1274    o modifications that affect AIM experiment results (update output.txt):
1275      - no advection of S at top interface Nr (pkg/generic_advdiff)
1276      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1277    o AIM pkg:
1278      - include stability function into surf.Flux derivative relative to Tsurf
1279      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1280    
1281    checkpoint53e_post
1282    o merged cylindrical coord configuration
1283    o added rotating_tank experiment
1284    checkpoint53e_pre
1285    
1286    checkpoint53d_post
1287    o faulks upgraded: re-generate output.txt that have changed:
1288       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1289    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1290    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1291    o added Sadourny discretization of Coriolis
1292      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1293      - re-enabled use of omega3 (useAbsVorticity)
1294    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1295      vector-invariant equations
1296      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1297    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1298      hopefully without new bugs
1299      - still to do: biharmonic friction for non-hydrostatic w
1300    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1301    o regenerated output for global_ocean_ebm (using -ieee)
1302    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1303      of mom_common/
1304      - simple re-arrangement of instructions within computing loop
1305    checkpoint53d_pre
1306    
1307    checkpoint53c_post
1308    o new version of coupler for AIM+thSIce and Ocean models
1309     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1310     - land: change Evaporation of snow
1311     - aim with thSIce: fix bug in snow-precip.
1312    o changes to calc_gw.F
1313     - bug fix for w^2 term near the bottom boundary
1314     - (hopefully) improve the lateral slip boundary condtions for use with
1315        partial/looped cells
1316      - because the bug fix changes two verification experiments anyway (exp5
1317        and plume on slope), change the lateral boundary condition from half slip
1318        to the value of no_slip_sides
1319    o ebm package wasnt quite up to the parallel task. Fixed that.
1320    o Adjoint of EBM package + verification
1321      * TLM OK
1322      * ADM not sufficient accuracy yet (needs further testing)
1323    
1324    checkpoint53b_post
1325    o Commiting new energy balance model to repository
1326      * package is pkg/ebm
1327      * verif. is verification/global_ocean_ebm
1328      * references are in ebm_driver.F
1329    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1330    C        Global thermohaline circulation. Part I:
1331    C        Sensitivity to atmospheric moisture transport.
1332    C        J. Climate 12(1), 71-82
1333    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1334    C        Global thermohaline circulation. Part II:
1335    C        Sensitivity with interactive transport.
1336    C        J. Climate 12(1), 83-91
1337    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1338    C        Destabilization of the thermohaline circulation
1339    C        by atmospheric eddy transports.
1340    C        J. Climate 7(12), 1870-1882
1341    o Will need long integration testing.
1342    checkpoint53b_pre
1343    
1344    o created pkg/mom_common in preparation for variable viscosity code
1345    o renamed and split ini_mnc_io
1346    o pkg/land: only liquid water can diffuse or run-off
1347    o AIM using land: soil wetness availability account for snow
1348    o added printMapIncludesZeros to EEPARMS namelist
1349    
1350    checkpoint53a_post
1351    o restore TAMC compatiility for exf_constants.h
1352      (no usage of _d in .h)
1353    o Additional storing in KPP in an attempt to fix
1354      TAMC problem with adjoint of KPP code.
1355      (no success...)
1356      Identical code works fine with TAF.
1357    o Fixed verification/natl_box_adjoint experiments.
1358      Initial conditions for Experiments 4 and 5 are now
1359      set to "SEAICE_initialHEFF=0", which is more reasonable,
1360      and hence gives results closer to that of Experiment 2.
1361      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1362    
1363    checkpoint53
1364    o stable checkpoint with up to date adjoint
1365      TLM tests only run for 1st grdchk at the moment. Its unclear if
1366      this is a code problem or a problem with resetting code for g_
1367      variables that is being autogenerated wrong.
1368      Otherwise:
1369       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1370       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1371         are both still in chaos following their security messes.
1372    
1373    checkpoint52n_post
1374    o various build (mostly genmake2) changes including:
1375      - ability to build/run more easily within Cygwin and MacOS X
1376      - more complicated Makefiles with a stronger dependence on Gnu Make
1377    o pkg/seaice modifications
1378      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1379        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1380        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1381      - changed proxy for geostrophic velocity and updated
1382        verification/lab_sea/results/* accordingly
1383      - removed ADI dynamic solver from pkg/seaice
1384      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1385        they caused a segmentation fault under certain circumstances
1386      - removed unused field WATR
1387    o bug fix in exf-package:
1388      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1389         now reflect that.
1390    o small fixes in the cal-package:
1391      - set reference date to first of January for the 'model'-calendar
1392      - failing of cal_CheckDate in cal_FullDate now actually results in a
1393        warning
1394    o small modifications in exf-package to increase flexibility:
1395      - change climtempfreeze from a constant to a runtime parameter that
1396        is specified in data.exf_clim (default = -1.9)
1397      - introduce runtime parameter windstressmax (default = 2.0) that is
1398        specified in data.exf
1399    o fix in pkg/thsice:
1400      - update Evap (Tsf changes) to be consistent with Latent heat flux
1401      - maintain snow precipitation unchanged (even if Tsf >=0).
1402     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1403    
1404    checkpoint52m_post
1405    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1406      this does not change any of the results, because myIter=0 in swfrac always
1407      lead to jwtype=2 (the default anyway), but the call makes little sense
1408      as a default
1409    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1410    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1411      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1412    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1413    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1414    o extending useSingleCpuIO option to work with new exch2 I/O format
1415      - old-style, missing-tile I/O is still accessible by defining CPP
1416        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1417    o monitor package can write to NetCDF files and/or STDOUT
1418    o fix re-definition bug in MNC_GRID_INIT_ALL()
1419    o doc/api_reference added
1420      - a framework for building an API Reference Manual using all
1421        the "protex" comments embedded in the code
1422      - see pkg/generic_advdiff, pkg/mnc for examples
1423    o MNC:
1424      - make myThid the last argument for all subroutines
1425      - new default for the grid files: NO halos
1426      - add useMNC and other run-time flags
1427      - separate per-file-group handling of the unlimited dimension
1428      - early initialization of MNC w/ flags read at the eeboot stage
1429        and lookup tables set in initialize_fixed
1430      - write all MNC output to a freshly-created directory
1431    o thermodynamics sea-ice (thsice) is now tested with testreport.
1432    o test exp. advect_cs: use the standard cs32 grid ; update output.
1433    o Added functionality to grdchk:
1434      pick global i,j,k position (or nearest wet) where to perform check.
1435    
1436    checkpoint52l_post
1437    o new land formulation:
1438      a) use ground enthalpy as prognostic variable to ensure exact
1439         energy conservation.
1440      b) account for water temperature and for latent heat of freezing
1441         in all processes (rain, run-off, ground storage)
1442      c) compute surface and ground temperature implicitly.
1443    o aim_v23 modification for new land model:
1444      a) Treat separately land / ocean / sea-ice surface fluxes
1445         to allow implicit computation of land & sea-ice surface temp.
1446      b) add snow precipitation.
1447    checkpoint52l_pre
1448    
1449    o fix problem (when 1 tile is empty) in min/max monitor.
1450    o fix bug in timeAve (u,vZetatave in common block)
1451    o no restoring terms under ice for pkg/seaice
1452    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1453    o bug fix for pkg/seaice pickups
1454    o change MNC call locations and add coordinate attributes
1455    o mask vorticity at the corner ; affects global_ocean.cs output
1456    o fix ini_curvilinear_grid ; test CS experiments with mpi
1457    o aim.5l_cs: modify sea-ice fraction input file ; update output
1458    o exf: Adding simple range check routine for exf fields after read
1459    
1460    checkpoint52k_post
1461    o removed top-level directory "diags"
1462      - we migrated these functions to pkg/timeave a long time ago
1463    o fixed bug introduced in pkg/monitor
1464    o accuracy ctrlprec = 32 insuffient for gradient checks using
1465      averaged fields (I/O via cost_averages)
1466      -> use ctrl.h in active_file*.F to control I/O precision.
1467    o paramter list of CALL ADTHE_MAIN_LOOP
1468    o added initial do_the_model_io to ecco

1473    checkpoint52j_post
1474    o fix nchklev in tamc.h for global_ocean...
1475    o Bringing flow and store directives up-to-date
1476    o Really weird thing!
1477      call do_the_model_io from the_main_loop with parameters
1478      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1479      TAF places a faulty re-call of initialise_varia
1480      after cost_final call which should not be there!
1481    checkpoint52j_pre
1482    
1483    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1484      error messages
1485    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1486    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating

1515      there is no sea-ice on cube faces 1, 2, 4, and 5.
1516    
1517    checkpoint52f_post
1518    o added exch2 cube routines to pkg/exch2

1521    checkpoint52f_pre
1522    
1523    checkpoint52e_post
1524    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1525      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1526    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1527      to work with implicit vertical advection and AB ;
1528    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1529    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1530     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1531    checkpoint52e_pre
1532    
1533    o fix bug in impldiff when Nr=1 or Nr=2.
1534    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1535    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1536    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1537      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1538    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1539    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1540    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1541    
1542    checkpoint52d_post
1543    o re-tiled many expts to allow comparison in multi-processor mode
1544      - updated output accordingly
1545      - changed hs94.128x64x5 to use intial T from file rather than use the
1546        random number generator
1547    o add infrastructure in model routines for fizhi and gridalt packages
1548    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.

1551      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1552      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1553        of surface winds for the cube
1554      (A verification experiment, based on global_ocean.cs32x15, but with
1555       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1556       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1557       complete with example surface forcing files and matlab scripts to look
1558       at the output and compare it with that of global_ocean.cs32x15.)
1559    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1560       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1561       to conform to the common rule.
1562    o check-in the first version of the coupler + interfaces for multi-components
1563       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1564       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1565       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1566       - ocean and atmos. share the same horizontal grid (no interpolation).
1567       - exchanges between component and coupler is done in forward_step
1568    o new verification experiment, cpl_aim+ocn:
1569       coupled ocean - AIM atmosphere on cs32 grid.
1570    
1571    checkpoint52d_pre
1572    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1573    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1574    
1575    checkpoint52c_post
1576    o Fixing OPTIONS files for use of exf:
1577      - ALLOW_ECCO not needed
1578      - ECCO_CPPOPTIONS.h should not be included from
1579        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1580        as has been the case in the past
1581      - All cal/exf related options are currently set in
1582        single header file. Should remain so until we
1583        agree on a consistent new policy.
1584    o Removed all CPP options for cal package.
1585      cal has no more CPP options.
1586    o modified STOREs in GAD_ADVECTION
1587    o corrected key comp. for passkey
1588    
1589    checkpoint52b_post
1590    o new version: "thsice" of thermodynamic sea-ice pkg:
1591     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1592     - modify fluxes but do not change theta directly;
1593     - light cleaning of bulk_force pkg (still needed with thsice).
1594     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1595       + output_thsice.txt to test thsice & bulk_force pkgs.
1596    o put back grid & coriolis monitor output.
1597    checkpoint52b_pre
1598    
1599    o call "do_the_model_io" at the beginning (=> dump initial state)
1600    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1601    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1602      (need info on NUMBER_OF_PTRACERS)
1603    o missing PTRACERS headers in some routines
1604    o default tamc.h in pkg/autodiff supposed to crash
1605      to ensure proper customization
1606    
1607    checkpoint52a_post
1608    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1609      - moved surfaceTendencyTice from pkg/seaice to main code
1610      - subroutine FREEZE_SURFACE now limits only surface temperature
1611        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1612        => new output.txt for global_ocean.cs32x15 & global_with_exf
1613      - keep the old version of FREEZE for backward compatibility;
1614        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1615      - corresponding modifs for TAF directives
1616    o added surface flux output variables to TIMEAVE_STATVARS

1620      but no warning issued by TAF
1621    
1622    checkpoint52a_pre
1623    o some bug fixes for #undef REAL4_IS_SLOW
1624    
1625    checkpoint52 = ecco_c52_e35
1626    o after testing adjoints of checkpoint51u_post
1627    
1628    checkpoint51u_post
1629    o this is the post-merge tag of the ecco-branch
1630      (needs another clean checkout and re-testing)
1631    o various natl_box_adjoint configs and results
1632      but no input fields
1633    o obcs adjoint not yet merged!
1634    o adding ECCO global 1x1 and 2x2 degree configs
1635    o updated/extended some store directives for seaice
1636    o pkg/ecco now containes ecco-specific part of cost function

1640      (new namelist ecco_cost_nml)
1641    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1642    
1643    checkpoint51t_post
1644    o this is the pre-merge tag of the ecco-branch
1645    
1646    checkpoint51s_post
1647    o cleanup: removed various obsolete #define-s
1648    o pkg/grdchk
1649      - renamed 'ph-grd 3' to 'grad-res'
1650      - merged from ecco-branch
1651        (remaining bug fixes for obcs gradient checks)
1652      - additional high-precision output for testreport
1653        (grep for 'precision_grdchk_result')
1654    
1655    checkpoint51r_post
1656    o cleaned up or removed CPP_OPTIONS.h files
1657    o updated results for some of the tests to reflect the new
1658      optfiles (-ieee: -O0 instead of -O3)
1659    
1660    checkpoint51q_post
1661    o cd_code:
1662      - moved cd_scheme.F -> cd_code_scheme.F
1663      - separate read_checkpoint from cd_code_ini_vars.F
1664      - separated cd_code part from write_checkpoint

1670        xx_/adxx_ I/O
1671      - ctrl_pack/unpack cleaned
1672        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1673      - confined inclusion of AD_CONFIG.h to where necessary.
1674    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1675    
1676    checkpoint51p_post
1677    o create initial cd_code package
1678      - WARNING: the initialization of fields within packages
1679        is broken because INI_FIELDS (where READ_CHECKPOINT is
1680        called) is called *before* PACKAGES_INIT_VARIABLES.
1681        This seems to be backwards since
1682        1) its important to initially zero the entire field including
1683           the "halo" region
1684        2) zeroing needs to be done *before* reading pickup info
1685           and the pickup call might or might not happen in any
1686           particular run
1687      - this needs an overhaul for R2
1688    o cleanup verification/*/code/GMREDI_OPTIONS.h
1689    o cleanup testreport

1722      - moved surfaceTendencyTice from pkg/seaice to main code
1723      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1724      - subroutine FREEZE now limits only surface temperature
1725        (this means new output.txt for global_ocean.90x40x15,
1726         global_ocean.cs32x15, and global_with_exf)
1727    o added surface flux output variables to TIMEAVE_STATVARS

1881    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1882      - autodiff, ctrl, exf, grdchk, seaice
1883      kept separate packages
1884      - cost, ecco, obcs
1885    o updating verification/internal_wave, verification/lab_sea
1886      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1887    
1888    checkpoint50i_post
1889    o Preparing next differentiable checkpoint and sync
1890      of MAIN vs. ecco-branch
1891      - 1st step: this one is differentiable
1892      - 2nd step: next(! not this) checkpoint will have updated packages
1893                  from ecco-branch)
1894    
1895    checkpoint50h_post
1896    o new package "land": provide surface BC for AIM.
1897    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1898    o AIM: use true log-P extrapolation for near surface temp (= as in
1899        F.Molteni paper) ; update aim.5l_cs output.
1900    o New variable in PARM03 for more flexible pickups
1901    o somewhat cleaned package initialisation sequence for
1902      ctrl/ cost/ ecco/ in packages_... routines
1903    
1904    checkpoint50g_post
1905    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1906      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1907      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1908        made the default because of faster convergence than ADI
1909    
1910    checkpoint50f_post
1911    o exf totally restructured
1912      - replaced all exf_set_ routines by one generic exf_set_gen.F
1913        and made sure it's still differentiable
1914      - split exf_getffields.F into new exf_bulkformulae.F
1915      - exf_inscal_/exf_outscal_ suffixes consistent with field names

1927    
1928    checkpoint50e_post
1929    o make KPP work with PTRACERS
1930     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1931       nearly a copy of kpp_transport_s
1932     - there is no analogue to SurfaceTendencyS, so I have to use
1933       gPtr(of the surface layer) instead
1934    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1935    checkpoint50e_pre
1936    
1937    checkpoint50d_post
1938    o change kpp output from multiple-record state files to single-record state
1939      files analogous to write_state.F
1940    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1941      analogous to the cg2d-related output.
1942    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1943      so that writing to internal file fn (with length 512) fails.
1944    checkpoint50d_pre
1945    
1946    checkpoint50c_post
1947    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1948    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1949    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1950    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1951    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1952    
1953    checkpoint50c_pre
1954    Merging from release1_p13:
1955    o bug fix for pkg/seaice dynamic solver
1956    o Added SEAICE_initialHEFF to pkg/seaice
1957    
1958    checkpoint50b_post
1959    o store u*,v* in gU,V instead of in guNm1,gvNm1
1960    o in order to put the momForcing out of the Adams-Bashforth:
1961      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1962      to timestep.F
1963    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1964    o re-generate output for highly sensitive test-exp:
1965       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1966    
1967    checkpoint50b_pre
1968    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1969    o corrected CPP option mismatch in exf_Bulk... functions for case
1970      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1971    
1972    checkpoint50a_post
1973    o Bug fix for merging between c50 and KPP.
1974      ikey was passed from thermodynamics to kpp_calc via
1975      common block rather than being recomputed in kpp_calc,
1976      in contradiction with new key itdkey.
1977      New key ikppkey created, and tamc.h headers updated.
1978    
1979    checkpoint50
1980    - 2nd step of merge with ecco-branch:
1981      merge changes in ecco-branch back into main trunk
1982    - bug fix in find_alpha
1983    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1984    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1985    - merged some sliced AD support routines
1986    
1987    checkpoint49
1988    merged from ecco-branch:
1989    o exf:
1990      - Enable initialisation of forcing fields to constant
1991        (runtime) values.
1992      - in exf_getffields.F
1993        Reduce i-/j-loop to interior domain, discarding overlaps.
1994        That also fixes wrong TAF-key computations for key_1, key_2
1995        with bulf formulae.
1996      - exf_init.F modify #ifdef for exf_init_evap
1997      - exf_getffieldrec.F, ctrl_getrec.F
1998        The following INT-usages are not safe:
1999          fldsecs  = int(fldsecs/fldperiod)*fldperiod
2000          fldcount = int(fldsecs/fldperiod) + 1
2001        and were modified.
2002    o autodiff: checkpoint_lev...
2003      - updated storing for bulk formulae (some arrays were missing)
2004      - added state for seaice package
2005      - synchronized with main branch
2006    o DIVA:
2007      Modif.s in
2008      - the_main_loop.F
2009      - the_model_main.F
2010      and added cost_final_restore.F cost_final_store.F
2011      o With these changes, it is possible to fully separate
2012        the first forward run to compute the cost function (mdthe_main_loop)
2013        and adjoint runs over individual DIVA intervals (adthe_main_loop)
2014        into separate model executions.
2015        This enables better tuning of DIVA to given queue sizes.
2016      o Loss of cost function value in consecutive DIVA runs is
2017        fixed by storing to 'costfinal' file.
2018      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
2019        beginning/end of adjoint integration is accounted for.
2020      The current changes apply to TAF-1.4.26.
2021      TAF has one remaining bug, requiring one manual change
2022      (see MITgcm manual).
2023    o cal: synchronized between MAIN and ecco-branch
2024    
2025    checkpoint48i_post
2026    o Changes to restore differentiability of code w.r.t. previous tag
2027      (mostly adding new routines to make list and replacing
2028      pressure by totPhiHyd).
2029    o Updated and merged grdchk package
2030      - has both ADM and TLM checks
2031      - works for single- and multi-proc.
2032      - output cleaned
2033      - worked successfully for parallel DIVA
2034    o genmake:
2035      - Adding -platform=SP4
2036      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
2037    o Modif. for DIVA:
2038      ctrl_unpack should not be called in intermediate DIVA interval.
2039      (similar thing would apply for active files such as
2040      tbar, sbar, psbar, which should not be reinitialised;
2041      only relevant for ecco-branch)
2042    
2043    checkpoint48h_post
2044    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
2045    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
2046    o Added SEAICE_initialHEFF to pkg/seaice
2047    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
2048    
2049    checkpoint48g_post
2050    --- EOS:
2051    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
2052      store total Potential in totPhyHyd for diagnostics & EOS.
2053    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
2054    --- Pressure/geopotential gradient:
2055    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
2056    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
2057      ( changes results of global_ocean_pressure )
2058    o NLFS + z-coord.: add eta*Rho' contribution.
2059    o accurate phiHyd when using interface-W at the middle between 2 centers
2060     ( changes results of ideal_2D_oce )
2061    o includes r* 2nd term in potential gradient.
2062    
2063    checkpoint48f_post
2064    Merging from release1_p12:

2071      (SBO) core products, including oceanic mass, center-of-mass,
2072      angular, and bottom pressure (see pkg/sbo/README.sbo).
2073    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
2074      to avoid negative values in shallow regions.
2075      - updated verification/natl_box/results/output.txt
2076      - updated verification/lab_sea/results/output.txt
2077    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
2078    o Added useSingleCpuIO option (see PARAMS.h).
2079    o Updated useSingleCpuIO option in mdsio_writefield.F to
2080      work with multi-field files, e.g., for single-file pickup.
2081    o pkg/seaice:
2082      - bug fix in growth.F: QNET for no shortwave case
2083      - added HeffFile for specifying initial sea-ice thickness
2084      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation

2087    o pkg/seaice:
2088      - adjoint-friendly modifications
2089      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
2090    
2091    checkpoint48e_post
2092    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
2093    o dynamics: change definition of computational domain & adapt mom_fluxform
2094      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
2095    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
2096        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
2097        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
2098        global_ocean.90x40x15 global_with_exf global_ocean_pressure
2099        inverted_barometer solid-body.cs-32x32x1
2100      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
2101    
2102    checkpoint48d_post
2103    o in preparation for r*:
2104     a) use pre-computed gradient of hydrostatic potential:
2105        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
2106     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
2107        => affects results of glob_oce_pressure (different truncation error)  
2108      update output.txt of ideal_2D_oce & global_ocean_pressure
2109    
2110    checkpoint48d_pre
2111    o in preparation for r*:
2112      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
2113      pass the 2 comp. of the grad. as arguments to momentum S/R.
2114      but for the moment, only used if it does not change the results.
2115    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
2116    
2117    checkpoint48c_post
2118    Modifications in treatment of initial flux forcing controls
2119    to avoid extra storing of flux fields.
2120    
2121    checkpoint48c_pre
2122    o Added tidal_basin_2d experiment (currently 1D!)

2130    
2131    checkpoint48a_post
2132    o In preparation for r*, use temp. array to compute vertical transport
2133       in flux-form momentum pkg. => change results of few test-exp.
2134      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
