4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o profiles: adding ptracer and ssh
8    o testreport: change multi-test output-file name
9      (from output.txt.{name} to output.{name}.txt)
10    o profiles: now ok for mutli-threaded case
11    o seaice: add 4 parameters for different advection schemes for area,
12      (effective) seaice thickness, enthalphy, and snow height. Their default
13      is the standard parameter SEAICEadvScheme
14    o calc_gw:
15     - add cosFacU in zonal viscous flux (harmonic.visc.).
16     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
17       of tutorial_plume_on_slope.
18    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
19    o calc_gw: true flux-form, account for horizontal grid spacing.
20      update rotating_tank results, but not plume_on_slope (affected at
21      truncation level, 11 digits).
22    
23    checkpoint58l_post
24    o calc_gw:
25     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
26     - remove side-drag for now (need to fix it); update plume_on_slope results.
27     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
28    o commit code to make SST/SSS weights spatially variable
29      (based on either variable in-situ or variable initial T/S weights)
30    o pkg/ecco:
31      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
32        now based on horizontally varying weights wthetaLev, wsaltLev
33      * cost_averagesflags now returns year indices in addition to day, month
34      * sflux balance is performed on annual basis
35        (sflxumm, sfluxmm2, bal_sfluxmm)
36      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
37        including separate counting and multipliers
38    o pkg/rbcs
39      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
40    
41    checkpoint58k_post
42    o testreport:
43     - always build in dir. "build" (if not there, mkdir build instead of building
44       & running in input)
45     - run in dir run (if it exists), in build otherwise.
46     - call prepare_run (if input/prepare_run exists)
47     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
48    o pkg/exf modifications to interpolation and rotation routines for more
49       reasonable treatment of North Pole singularity: for tracers North Pole
50       value is set to northernmost zonal-mean value, for zonal velocity it is
51       set to zero, and for meridional velocity it is set to northernmost value.
52    o pkg/exf/exf_check_range.F
53     - add tile index to diagnostics and move stop statement to the very
54       end of the routine.
55    o pkg/diagnostics: (diagnostics_main_init.F)
56      define title of isomorphic variables according to the current config.
57    o pkg/thsice with pkg/seaice dynamics:
58    - fix domain of computation (interior only, required for exf) and do exchanges
59    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
60    o towards a standard way of dealing with multi-threading in MONITOR
61      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
62    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
63       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
64    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
65    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
66    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
67       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
68    o tracer advection:
69     - clean-up and simplify calc_common_factors.F
70     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
71       advection subroutine (but still not used within DST advection S/R)
72    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
73    
74    checkpoint58j_post
75    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
76      from file (collects calls previously in FORWARD_STEP)
77    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
78    o adjoint store dir. adjusted accordingly
79    o genmake2
80      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
81    
82    checkpoint58i_post
83    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
84      on wind stress (SEAICEstressFactor defaults to 1.)
85    o Total number of Timers is finite (<=40): comment out 2 non-essential one
86      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
87    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
88      on CS-grid: no longer loosing mass.
89    o exf & curvilinear-grid: no longer modify longitude xC & xG.
90    o pkg/ggl90: fix sloppy output and fix a bug
91    o pkg/seaice: added SEAICEuseEVPpickup parameter
92      - Set to false in order to start EVP solver with
93        non-EVP pickup files when using SEAICEuseEVP
94      - fix sign error in diffusion in seaice_calc_rhs
95    
96    checkpoint58h_post
97    * Modifications for bottom topography control
98      o replace hFacC by _hFacC at various places
99      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
100      o add non-self-adjoint cg2d_nsa
101      o update autodiff support routines
102      o re-initialise hfac after ctrl_depth_ini
103      o works for 5x5 box, doesnt work for global_ocean.90x40x15
104    * Adding verification for 5x5 box (4-layer) bottom topography control
105    
106    checkpoint58g_post
107    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
108       used for mean seasonal cycle, mean diurnal cycle); add an example
109       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
110    o pkg/ggl90:
111      - add parameter (minimum surface kinetic energy)
112      - fix bug (avoiding division by zero)
113    o couple pkg/thsice to pkg/seaice:
114      - modify advection in seaice to accomodate new scalar fields to be advected
115      - only muliDimAdection scheme work with seaice/thsice
116      - mapping of thsice-variables to seaice-variables, back and forth
117      - does not break the verification experiments, but does not give the
118        desired results either
119    o pkg/seaice
120      - make (default) second order advection a bit less confusing?
121    
122    checkpoint58f_post
123    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
124      to pkg/seaice):
125      - new routines thsice_map_exf and thsice_get_exf provide the interface
126      - add an additional formal parameter to thsice_solve4temp
127    o pkg/exf:
128      - add new fields wspeed, snowprecip (to be able to couple to thsice)
129      - correct Stefan-Boltzmann constant
130      - new parameter for longwave surface emittance
131      - separate some stuff from exf_bulkformulae into new routines  
132        exf_radiation, exf_wind
133      - add new parameters and constants: longwave emissivity for ocean, ice
134        and snow, evaporation parameters over ice
135      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
136        either wind from stress or stress from wind
137    o pkg/thSIce:
138    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
139    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
140       and THSICE_CALC_THICKN
141    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
142    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
143      to make debugging easier.
144    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
145    o pkg/bulk_force:
146      - clean-up comments and parameters ;
147      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
148    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
149      generate new output for test-experiment: aim.5l_cs.thSI
150    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
151      testreport accordingly
152    
153    checkpoint58e_post
154    o SEAICE_CGRID adjoint done
155    o R_STAR adjoint implemented.
156      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
157      * need to sort out init. of h0facc, etc.
158    o Make pkg/profile fully independent of ecco,cost, etc. stuff
159      to be able to use it in pure forward.
160    
161    checkpoint58d_post
162    o upgrade simple test-experiment to tutorial example:
163     step.1: duplicate the experiment and (step.2) will remove the old copy.
164      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
165      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
166      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
167      tutorial_global_oce_biogeo    <- copy of dic_example
168      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
169      tutorial_plume_on_slope       <- copy of plume_on_slope
170      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
171      tutorial_global_oce_optim     <- empty for now (David ?)
172      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
173     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
174    o correct a sign problem in cost_scat.F
175    o obcs and ptracers: fix boundary conditions for advections schemes
176      with larger stencil
177    o thsice adjoint: start
178    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
179      completeness
180    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
181      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
182    o ptracers adjoint:
183      * avoid extensive recomputatations
184      * fix missing re-init. of gptr (missed by TAF)
185    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
186      me to turn off the excessive output to STDOUT that this package produces
187    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
188      and add those terms in Vector-Invariant formulation.
189    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
190      if the control period (xx_hfluxperiod etc) is 0
191    o in profiles pkg, clean routines and fix details
192    o in ecco pkg, reading ssh data:
193      fix problem in case the model does not start at iter0=0
194    o fix mnc-pickup/restart for ptracers
195    o new package prifiles:
196      code to compute profile-based cost by Gael Forget
197      (modifs in ecco, ctrl, autodiff)
198    o Benign bug fix in initialization (spotted by M. Mazloff) of
199      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
200    
201    checkpoint58c_post
202    o adjoint: finish NLFS adjoint and provide reference output in
203      verification/global_ocean.90x40x15/results_ad_nlfs
204    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
205      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
206      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
207      with SEAICE_CGRID defined.
208    o move calendarDumps from "data" to "data.cal" and clean-up the code
209      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
210    o add useEXF & useCAL flags (for now, set in hard-coded way)
211    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
212      (were missing in NH mode, and wrong in quasihydrostatic mode).
213      waiting for Chris updated version of calc_gw to add those CALLs.
214    o fix bug in quasihydrostatic S/R ;
215      add a test for this option: global_ocean.90x40x15.qshyd
216    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
217      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
218    o add on/off flag useOffLine for package OFFLINE
219    o seaice:
220      - modify advection so that it works also on the C-grid
221      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
222        problem in multi-tile runs with C-grid
223      - add flags for clipping ice velocities and/or masking solver forcing
224      - fix drag (ocean on ice) formulation and a bug that caused noise in the
225        C-grid solver
226      - added a few comments to seaice_diffusion.F
227      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
228        are now exclusive)
229      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
230        required re-ordering the code a little:
231       + make DAIRN global variable (defined in SEAICE)
232       + move computation of the viscosities eta and zeta into a new separate
233         routine (because I need to recompute them in seaice_ocean_stress.F)
234    
235    checkpoint58b_post
236    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
237      update output.txt of exp. aim.5l_cs.thSI
238    o various mnc cleanups and improvements:
239      + shrink lookup tables by factor of ~4
240      + better error reporting when running out of lookup space
241      + able to handle longer path/file names (up to 500 chars)
242    o adjoint:
243      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
244      - TBD: "hidden" mom_vecinv recomp. in dynamics
245    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
246     (allow to differentiate between forcing components using new integer flags:
247      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
248     and add new flag to put Dissipation tendency out of Adams-Bashforth.
249    o ecco
250      - enable trend removal from SSH anomaly obs.
251    o adjoint
252      - a fix for PmEpR when #undef EXACT_CONSERV
253      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
254      - try to fix "hidden" recomp. in forward_step for NLFS
255        (NLFS seems broken sometimes after I checked it in)
256    o seaice:
257     - add c-grid version of the dynamic solver:
258       + three new routines that are the c-grid substitute lsr, dynsolver
259         and ostres
260       + put a few fields that were local to dynsolver into global common
261         blocks, so that I can move the computation of stresses etc into
262         seaice_lsr (saves coding but may break the adjoint).
263     - replace more hardwired parameters by runtime parameters
264     - add ice masks that mask the rhs of the implicit solvers where there
265       is no ice (commented out in seaice_dynsolver, because i am not sure
266       if this works properly), eventually this should replace the clipping
267       of ice velocities in seaice_dynsolver to +/-40cm/s.
268    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
269      include it only where its needed
270    o move balancing of fluxes before the call of external_forcing_surf
271    o seaice:
272      - correct units of turning angles (now they are really in degrees)
273      - move computation of GWATX/Y out of main routine into dynsolver
274      - initialize GWATX/Y in seaice_init
275    o Apply mask on Fresh-Water flux (needed for SSH forcing).
276      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
277    o seaice: add runtime flags for turning angles (default to zero)
278    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
279      and trend from exf forcing and ctrl control adjustments
280    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
281      (since checkpoint57x_post)
282    o change the default rotation period to 86164.s = the Earth rotation
283    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
284      and based on a reference stratification. Tested within hs94.cs-32x32x5.
285    o seaice advection: add code for choosing between the default (2nd order
286      central differences) and multiDim advection schemes provided by
287      pkg/generic_advdiff
288    o seaice:
289      - removed all references to SEAICE_GRID.h fields from
290        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
291        (cubed-sphere configuration will change a little)
292      - grid computations in seaice_init are obsolete now.
293      - cleaned up code a little so that is easier to read (hopefully).
294      - added new (better?) discretizations of default advection and diffusion
295        (turn on with SEAICEuseFluxForm)
296      - replace 1 in 3d global fields by kSurface in growth.F
297      
298    checkpoint58a_post
299    o seaice:
300      - bug fix in advect.F
301    o shelfice:
302      - separate shelfice load anomaly from pload (breaks with time
303        dependent forcing), => introduce constant field shelficeLoadAnomaly.
304        Its default is 0., but it may be computed more cleverly from (unknown)
305        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
306        done offline. A good approximation of the pressure load anomaly is
307        necessary to avoid large initial adjustment processes underneath
308        deep-reaching shelfice.
309      - small fix in ISOMIP shelfice_thermodynamics
310      - add more sophisticated thermodynamics of Hellmer (1989), this is
311        now the default
312      - give a few constants more intuitive names
313    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
314      if bulk formulae are used in long integration (especially EmPmR). Turn
315      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
316      if balancePrintMean, the imbalance that is substracted is printed to
317      STDOUT.
318    o fix bug (typo) in obcs_apply_eta.F
319    o add a new package shelfice which enables us to model the circulation
320      underneath shelf-ice with draughts of hundreds of meters.
321     - works
322     - to do: + include improved thermodynamics
323              + check whether kSurfC (from model/inc/SURFACE.h) can be used
324                instead of new field kTopC
325              + can we use topoFile, Ro_surf and existing code in ini_depth.F
326                instead of new field R_shelfIce and new code in ini_depth.F
327                and ini_mask_etc.F?
328              + adjust vertical mixing schemes?
329    o seaice pkg:
330     - add a cpp-flag to include a simple formula for a salinity dependent
331       freezing point of sea water at the surface
332     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
333       meridional stresses are now different (and hopefully correct)
334    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
335       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
336       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
337    o pkg/diagnostics: add options and parameters for regional-statistics
338       diagnostics ; define regions by reading a region-mask from a file
339       (might add other options later)
340    o pkg/bulk_force:
341     - add option and parameters to use AIM surface-flux formulae.
342     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
343       others forcing fields (defined in PARM05, parameter file "data") are loaded
344       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
345     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
346     - use the right EXCH call for uwind,vwind (to work on CS-grid).
347     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
348       and parameters (note: calcWindStress replaces .NOT.readwindstress).
349     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
350    
351    checkpoint58
352    o add "--embed-source" option to genmake2 which, when the supporting
353      tools can be compiled (as determined by genmake2) will turn on the
354      embed_files package which then embeds the entire MITgcm source code
355      (*.[fFhc] + Makefile) used for the build within the executable
356      - requested by CNH but off by default
357      - adds a paltry <9MB to the mitgcmuv executable in most cases
358      - only writes the output when useEMBEDSRC in eedata is true
359    o clean up 3-dim. relaxation codes:
360      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
361      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
362      * Thanks to Tom Haine for testing!
363    
364    checkpoint57z_post
365    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
366      affects output (@ truncation level) of exp. plume_on_slope ; updated.
367    o fix the pickup behavior for obcs in combination with ptracers
368    o fix a bug in ptracers_external_fields_load
369    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
370      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
371    o transfered surface NH pressure to eta field (if exactConserv).
372    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
373         and update lab_sea output.txt file.
374    o completing 3-dim. relaxation code: additional term
375         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
376      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
377      * At compile time, in "EXF_OPTIONS.h" set
378          #define  ALLOW_CLIMTEMP_RELAXATION
379          #define  ALLOW_CLIMSALT_RELAXATION
380      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
381          tauThetaClimRelax3Dim = 15552000.0,
382          tauSaltClimRelax3Dim  = 15552000.0,
383      * 3 cases:
384          1) Use a constant-in-time 3-dim. field
385          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
386          3) Real-time relax. to time-evolving prescribed field
387    o Adding Laplacian-type smoothness constraint on
388      initial and boundary (forcing) controls (ic, bc)
389      * enable at compile-time via
390        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
391      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
392      * Absolute scale somewhat unclear so far
393      * no area weighting was included since no other cost term does so far
394    
395    checkpoint57y_post
396    First step for a NLFS adjoint
397    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
398    o new init. routines for calc_r_star, calc_surf_dr
399    o still need to deal with ini_masks_etc
400    o testreport seemed happy
401    checkpoint57y_pre
402    
403    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
404    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
405    o add new offset feature to offline pkg (plus minor cleanup)
406    o cfc fixes for final year of integration
407    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
408      be in GCHEM_OPTIONS).
409    
410    checkpoint57x_post
411    o fix testreport Pb in multiple test experiment.
412    o cleanup our namelist syntax in verification:
413      - make it more F95 standards compliant (some work still needed)
414      - allows the vast majority of our tests to work with gfortran
415    o Non-Hydrostatic:
416     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
417     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
418    o Allow to apply AB on T,S rather than on AB(gT,gS):
419     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
420     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
421       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
422     - need a "clever" read_pickup to restart from the other AB formulation
423    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
424    o remove some unused variables (reduces number of compiler warnings)
425    o adjoint
426      * Disable useVariableViscosity for adjoint for time being
427        (there are a number of extensive recomputations)
428      * Initialize certain variables needed for adjoint
429    
430    checkpoint57w_post
431    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
432                 fix the singleCpuIO RS version of MDSWRITEFIELD
433       and add a WARNING if using globalFiles=T with multi-processors.
434    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
435      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
436    o tracer advection scheme:
437      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
438       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
439       was not very convenient).
440      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
441       (further tests needed for the implicit DST & Flux-Limiter schemes).
442    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
443      and sRef for convenience, handy, when you want to initialize
444      ptracers in a large domain with a constant non-zero value. Also,
445      untangle ptracers_init.F a little.
446    
447    checkpoint57v_post
448    o change dome exp. to use variable viscosity in side-drag terms.
449    o remove all the files from the cfc_offline test since they are now
450      incorporated into tutorial_cfc_offline which has been producing
451      identical results for a few days of testing
452    o add new parameter: sideDragFactor to enable half-slip-side BC
453      and change side-drag S/R to use viscosity from mom_calc_visc
454      (can switch back by setting sideDragFactor=0.); affects results at
455      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
456       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
457    o vorticity & strain are now computed without masking, to account for
458      no-slip-side BC in variable viscosity calculation ; mask is applied
459      anyway later on, before computing advection/coriolis terms.
460    o modify exp4 to test new obcs support for reading from external files
461      and for passive tracers
462    o fix behavior of ptracers_monitor when monitor output is written to a
463      netcdf-file; still not independent of monitor.F (writes in the same
464      file).
465    o change default value of tRef (put a uniform, meaningful value for ocean
466      & atmos) and initialize sRef (was missing, as Martin mentioned).
467    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
468      to be proportional to enstrophy dissipation length.  Thus,
469       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
470      This is now consistent with Smagorinsky and with the manual.
471    
472    checkpoint57u_post
473    o OBCS and PTRACERS: add open boundary support for passive tracers
474      - either use homogenous (pseudo) v.Neumann conditions or prescribe
475        OB-values from file; this is not different from the way theta and salinity
476        are treated
477      - however, Orlanski-radiation conditions are not supported, and the model
478        will stop if you use pTracers and Orlanski at the same time.
479      - beefed up the rountine obcs_external_fields_load: now only those open
480        boundary values are overwritten with values from files for which there
481        are really files, otherwise the OB-fields remain untouched. This makes
482        it possible to use different OBs at different ends of the domain (as
483        with EXF)
484    o reduce number of exch calls in shap_filt (s2).
485    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
486      truncation level) 4/5 MLAdjust test results (11&12 digits match).
487    
488    checkpoint57t_post
489    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
490    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
491      same truncation, independent of the face number: affects affects several
492      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
493    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
494      note that biharmonic viscosity + no-slip was not tested in any experiment.
495    o fix bug in non-linear free-surf side-drag ; generate new output for
496      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
497    o make mnc honor the writeBinaryPrec flag for most kinds of output
498    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
499    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
500      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
501    o add brackets in multi-terms sum to get same truncation, independent of
502      the face number (manage to get exactly same value of gU,gV at the cs-edge)
503      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
504    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
505      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
506      a maximum grid-scale Reynolds number.  Also, changes all length calculations
507      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
508      Suggested values of viscosity parameters found in mom_calc_visc.
509      Many new viscosity diagnostics available.
510    
511    checkpoint57s_post
512    o Add clearing-house for viscosity calculations, mom_calc_visc and
513      correct numerous bugs in LeithD and Smagorinsky discretizations.  
514      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
515      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
516      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
517      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
518      The Strain-Tension form is now called with useStrainTensonVisc=.true.
519      ViscAhStrain and viscAhTension are now retired.
520    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
521    o In response to JMC's bug report, genmake2 now ignores any soft-links
522      that it finds in the *current* directory when searching for files.
523      Soft-links found in any other source directories will still work as
524      they did before.
525    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
526      a C routine to unlimit the stack size
527    o mnc-ify pkg/aim snapshot vars
528    o mnc-ify pkg/land as requested by Daniel
529    o various changes to mnc including:
530      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
531      - output can now be grouped so that all files within a group
532          change the ITER portion of their names in lock-step together
533      - can now read ("global") PER-FACE (in addition to PER-TILE) files
534          and works with both EXCH1 and EXCH2 (but needs more testing)
535      - writing works for all verification test cases w/ g77 on Linux
536    
537    checkpoint57r_post
538    o make MNC variable initialization happen earlier
539    o add diagnostics for (almost) each term of the momentum Eq.
540    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
541    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
542    o remove MINIMAL_TAVE_OUTPUT option ;
543      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
544    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
545      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
546    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
547    o add time-dependent SST, SSS control
548    o cost terms in ecco/ modularized (new cost_generic.F)
549    o cost_averages routines are modularized (new cost_averagesgeneric.F)
550    o new infrastructure for seaice model vs. obs misfits in seaice/
551      * driver from the_main_loop.F is seaice_cost_driver.F
552      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
553      * gradient check in Exp. 6a of natl_box_adjoint/
554    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
555      (see README file)
556    
557    checkpoint57q_post
558    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
559    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
560      - bug was reported by Jean-Michel and Ian Fenty
561    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
562      update exp. cpl_aim+ocn output.
563    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
564      Needed for high-res. runs with large global files
565      to be able to limit tapelev size
566    o Changed some tests for adjoint:
567      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
568      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
569      * global_ocean.90x40x15/ back to default 3-level checkpointing
570    o Modifications to enable scripted COMMON to MODULE conversion
571      * verification/OpenAD/code/ has necessary scripts and description;
572      * converts, compiles and runs successfully;
573    
574    checkpoint57p_post
575    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
576    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
577      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
578    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
579    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
580      (was already the case for dissipation with mom_vecinv,
581       and also the case for grad.PhiHyd when staggered-timeStep)
582      This will allow to put dissipation out-off the AB time-stepping.
583     Unfortunately, affects truncation error. Update output of exp. that "fails"
584      (cg2d matching number) and leave the others for later: front_relax(10),
585      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
586      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
587    
588    checkpoint57o_post
589    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
590      (2) its ready to be documented during the 20050801 DocFest
591    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
592      for ideal_2D_oce and lab_sea on linux_ia32_g77
593    o set to #undef CTRL_SET_OLD_MAXCVARS_30
594      in global1x1_tot/code_seaice_adj to access indices 32, 33
595      (worth another tag)
596    
597    checkpoint57n_post
598    o adding precip control xx_precip 32
599    o adding swflux control xx_swflux 33
600    o Replacing 10 forcing penalty cost routines by 1 generic.
601    o Implementing partitioning in time-mean and variable adjustment
602      for atmos. state.
603    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
604    o in natl_box_adjoint:
605      * updated exp 1 to 10
606        (but does not have time-mean vs. variable split results yet)
607    o updated global1x1/*_seaice_adj/
608      to incorporate latest changes
609    o enable useSingleCpuIO for mdsio vector routines
610      (applies in particular to tapelev I/O)
611    o removed inefficient K-loop in all active_file*control*.F
612    
613    checkpoint57m_post
614    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
615      and advect_cs (use EXCH-2 and standard cs-32 grid files).
616    o pkg/exch2: filling of face-corner halo regions is optional
617      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
618    
619    checkpoint57l_post
620     tag before updating tutorials (pre-release-2)
621    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
622       for output and interpolation of input fields onto model grid)
623    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
624       Affects results of exp. rotating_tank ; update output.txt.
625    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
626          and taking the square quantity and/or using a fraction-weight field.
627    o fix aim_diagnostics_init.F mate numbers.
628    o add mnc output capability to diagnostics/diagstat and update
629      our cvsignore files for the ACSII output generated
630    
631    checkpoint57k_post
632    o lab_sea now uses diagnostics package and provides a suite of
633      new EXF diagnostics output.
634    
635    checkpoint57j_post
636    o exf
637      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
638        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
639        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
640      * extended diagnostics output
641        - now includes all EXF variables
642        - hs, hl moved to common block
643        - separate S/R for diagnostics, called after ctrl vector is added
644        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
645        - EXFqnet contains true Qnet (i.e. includes qsw)
646      * updated verif. lab_sea, global_with_exf
647      * Rearranging hflux (exf_mapfields -> exf_getforcing)
648        to ensure that diagnostics sees a true EXFqnet
649    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
650    o diagnostics pkg: change pointers so that 1 diagnostic can be used
651      several times with different frequencies.
652    o mnc-ify the thsice package as requested by Daniel Enderton
653      - the monitor--MNC output needs work
654      - many attributes need to be added (most are currently blank)
655    o mnc-ify theaim_v23 package as requested by Daniel Enderton
656      - many attributes need to be added (most are currently blank)
657    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
658    o add Sadourny like discretization to the 4th.O vorticity advection scheme
659    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
660      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
661         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
662    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
663     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
664    
665    checkpoint57i_post
666    o Diagnostics package was changed: diagnostic allocation is now deactivated
667      by setting an empty file name in the namelist (used to be by setting 0 frequency)
668    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
669      add 1rst Order upwind vertical Shear.
670    o add a quick fix for A/B checkpointing in OFFLINE mode
671    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
672      end-run around the C/Fortran linking horror in eesup/src/timers.F
673    o added pkg/runclock: allows user to terminate run based on wall clock
674    o added non-hydrostatic scaling parameter: nh_am2
675    o pkg/my82: futile attempt to make results compiler-independent by adding
676      some "_d 0", etc. no effect.
677    o for mnc output, fill the 'T' coordinate var with myTime and create a
678      separate 'iter' variable for iteration count
679    o pkg/diagnostics:
680      add new capability: output of Global/Regional & per-level statistics ;
681      tested against monitor output (including land & thSIce) on various exp.
682    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
683    
684    checkpoint57h_done
685      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
686      data.diagnostics, data.gchem, data.ptracers) is done.
687    
688    o pkg/diagnostics: prepare for Global/Regional statistics.
689      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
690    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
691      and rename it: DIFFERENT_MULTIPLE
692    
693    checkpoint57h_post
694    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
695    o pkg/diagnostics: change output frequency, now in seconds (instead
696      of Nb of iterations). This requires to change data.diagnostics.
697    checkpoint57h_pre
698    
699    o in mnc, let the user create the output dir if both mnc_outdir_date
700      and mnc_outdir_num are false
701    o add fflags() to pkg/diagnostics which allows one to specify, on a
702      per-file basis, the file precision [default behavior is unchanged]
703    o added diagnostics to pkg/kpp, including computation of mixed layer
704      depth based on a temperature/density criterion
705    o updated verification/natl_box to test the new pkg/kpp diagnostics
706    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
707    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
708    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
709      not mnc -- this mistake was found by JMC and is now corrected
710    
711    checkpoint57g_post
712    o add Adams-Bashforth 3rd Order time stepping:
713      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
714      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
715    checkpoint57g_pre
716    
717    o make lambda[Theta,Salt]ClimRelax spatially varying
718      (default remains spatially uniform constant based on tau)
719    o added new control variables
720      * init. uVel, vVel, etanN
721      * lambda[Theta,Salt]ClimRelax
722    o separate masks used for ctrl_pack/unpack 'from write_grid' output
723      (suggested by G. Forget)
724    
725    checkpoint57f_post
726    o add parameter "baseTime" = model base time = time at iteration zero
727      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
728      account for baseTime shift
729    o move Coriolis arrays from PARAMS.h to GRID.h
730    checkpoint57f_pre
731    
732    o mnc-ifying the seaice package
733    o introduced an alternative length scale calculation for use in the limiting
734      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
735    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
736    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
737      as well as grad(vort3).  Made it compatible with both approximate form
738      for the cubed sphere and full form of these gradients.  Added flag
739      useFullLeith to select between approximate and full form.  
740    o add "d0" in getcon.F to reduce differences between compilers/platforms
741      update output.txt of exp. fizhi-gridalt-hs
742    o change port_rand funtion to allow to set the seed.
743    o fix obscure MNC bug involving conversion between reals and integers
744      - it caused no problems with certain (eg. gcc, ifc) compilers but the
745        new version is now more standards-compliant
746    o adjoint-related modifications
747      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
748      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
749      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
750    
751    checkpoint57e_post
752    o Adding eddy stress controls a la Ferreira et al.
753    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
754    
755    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
756      update output.txt of exp. fizhi-gridalt-hs
757    o add more "Z" dimensions and associated coordinate vars to MNC
758    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
759    o parameter calendarDumps: when set, approximate months (30-31 days) and years
760      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
761      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
762      months and years.  Requires pkg/cal.
763    o diagnostics: add pickup functionality
764      - off by default for backwards compatibility
765      - current version only uses MDSIO -- MNC will be added
766    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
767    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
768    
769    checkpoint57d_post
770    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
771    o modify verification/ideal_2D_oce so that it tests the creation of mnc
772      output from the diagnostics package
773    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
774    o make genmake2 more portable by using ".$FS" instead of ".f" for more
775      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
776    o add coordinate variables to the MNC output from the diagnostics package
777    o change MNC-flags default value: true when useMNC=TRUE
778    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
779      the ability (off by default) to read the grid information using MNC
780    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
781    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
782    o do snap-shot diagnostics at the middle of the time-interval (instead of
783      at the end).
784    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
785      new test for AIM with thSIce + slab-ocean
786    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
787    o move state variable diagnostics to the beginning of the time step ;
788      (note: still needs some work specially for snap-shot diagnostics)
789      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
790    
791    checkpoint57c_post
792    o Change testing option (-ieee) to get closer agreement between g77 & ifort
793    o generate new output.txt files on faulks with g77 & the new -ieee option
794    checkpoint57c_pre
795    
796    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
797      update output.txt of exp. global_ocean.90x40x15
798    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
799      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
800    o add saltFlux(+File) forcing capability with periodicExternalForcing
801    o allow to use pkg diagnostics for GM-Redi & ThSIce output
802    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
803    o improvements for the MNC output from DIAGNOSTICS:
804      - correct handling of the unlimitied dimension
805      - all dims now have associated coordinate variables
806      - variables located at U, V, and Corner ("Z") points are now written
807        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
808        *all* data points are output
809    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
810    o added pkg/seaice/seaice_monitor.F
811    o mdsio_readfield.F can now read files visible only to master MPI process.
812    o pkg/seaice: some test code for ice-modified ocean stress
813    o exf_getffields interpolation defaults to bilinear for all scalar forcing
814      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
815      spurious negative numbers for precipitation and humidity.  Will cause
816      some small numerical differences for integrations using pkg/exf/exf_interp.F.
817    o pkg/ctrl/
818      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
819        May be enabled via doPackDiag
820      *  introduce z-scaling of
821         + gradient (doZscalePack) and
822         + control (doZscaleUnpack)
823    o pkg/mdsio/
824      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
825      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
826    
827    checkpoint57b_post
828    o simplify options in diagnostics_fill arguments (remove weird combinations)
829    o fix MNC coordinate variables so that they now contain per-face index
830      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
831      general, EXCH2 grids are only aligned to a "local" coordinate system
832    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
833    o Implement instantaneous output within pkg diagnostics:
834      setting a negative frequency in data.diagnostics produces
835     "snap-shot" output (as opposed to time-average if freq > 0)
836    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
837      NOTE: change ptracer diagnostics name: use 2 characters to work with
838            more than 9 tracers. Add also diagnostics of advect & diffus flux.
839    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
840      becomes the coordinate variable for the 'T' dimension
841    o add CF-style coordinate variables to MNC
842      - just a first cut:  numbers are meaningless on the cubesphere and
843        missing along the T axis but otherwise it works!
844    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
845    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
846    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
847      this is based directly on what the model compute, so that the content of
848      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
849    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
850    o clean up build options files for SunOS, in particular
851      - remove -traditional from xmakedepend
852      - change -xarch=v9 to -xarch=native for f77
853      - restore use of make (not gmake)
854      - add CC=gcc if using g77
855    o changes per discussion of AM, JMC, & EH3 today:
856      - move redundant "grid" variables out of "state" -- in preparation of
857        creating proper CF-style coordinate variables and in recognition
858        that any/all grid variables can be easily copied (eg. w/NCO) from
859        the grid files into any of the other NetCDF files
860      - *always* output grid variables with MDSIO (this will eventually be
861        changed)
862      - output MNC grid file if useMNC is true
863    o every instance of _END_MASTER() has been found and replaced with
864      _END_MASTER( myThid ) in order to satisfy certain picky Sun
865      preprocessors
866    o re-arrange diagnostics pkg initialisation:
867     - allow each package to extend the available diagnostics list
868     - add some checking and fix small problems (multi-threaded, ...)
869     - new S/R diagnostics_fill (replace fill_diagnostics):
870       look through the short list of active diag. (instead of the long list)
871       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
872    
873    checkpoint57a_post
874    o this set of changes restores TAMC compatibility
875      tested for global_ocean.90x40x15 adjoint on trough
876      (what a pain)
877    
878    checkpoint57a_pre
879    o some modifs in tools/build_options for sunos
880    o call ctrl_pack for ctrl at end for optimcycle=0
881    
882    checkpoint57
883    o add horizontal bi-harmonic viscosity for vertical velocity
884      - new parameter viscA4W (defaults to viscA4)
885      - affects only non-hydrostatic code
886      - to be done: no-slip lateral boundary conditions
887    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
888    o implement Implicit Vertical advection for pTracers
889    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
890      (implemented also for implicit vertical diffusion & advection)
891    o OBCS: extend application of tracer open boundary conditions
892      to a strip beyond the boundary of width Olx/Oly
893    o add call monitor to TAF set of required calls (flow directives)
894      and include in natl_box_adjoint
895    o untangle a few ifdefs related to cost, ctrl, autodiff
896      untangel a few ALLOW_ECCO_OPTIMIZATION
897    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
898      (theta2, salt2 in ecco_cost_weights)
899    
900    checkpoint56c_post
901    o OBCS as control variables
902      - update ctrl_ad_diff.list, obcs_ad_diff.list
903      - remove balance of obcs controls from default
904      - fix index bug nobcs in ctrl_init
905      - fix dummy fields filen in ctrl_pack
906      - add dummy weights for obcs
907    o lsopt: comment out fort.94 output
908    o optim:
909      - remove unnecessary header files
910      - adjusted namelists
911      - add xerbla.F to Makefile
912    o exf:
913      - multiple modifications of exf_check_range
914      - unit change in exf_init_runoff from [m/year] to [m/s]
915    o mdsio:
916      - i/o-vector change debugLevel from debLevA to debLevB
917    
918    checkpoint56b_post
919    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
920      is called from DO_THE_MODEL_IO
921      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
922      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
923      - clean up PTRACERS_WRITE_TIMEAVE a little
924    o add another verification experiment that tests both the cfc-pkg and
925      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
926      reactive tendencies treated inline with regular timestepping
927    o testreport previously did a lousy job of comparing small numbers, so
928      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
929      implemented in the little c-progam tmp_cmpnum.c which is embedded in
930      testreport.
931    o ptracers_monitor: bug fix for MPI
932    
933    checkpoint56a_post
934    o GCHEM: finish reorganizating the package
935      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
936        (introduces another 3D-array for each passive tracer, but only if
937        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
938        gchemTendency is not needed because the timestep is done separately)
939      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
940      - GCHEM is now---more or less cleanly---separate from PTRACERS
941      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
942        so clear to me how that should be done in a general way.
943    o CFC: improve formatting of output in CFC_ATMOS
944    o PTRACERS:
945      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
946        that ALL experiments with ptracers enable can be checked. This makes
947        GCHEM_MONITOR obsolete.
948      - include a runtime parameter PTRACERS_monitorFreq that defaults to
949        monitorFreq
950      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
951    o add PTRACERS (PTR0[1-5]) to testreport output
952    o exf_check_range:
953      * default changed to .TRUE.
954      * will check values for niter0 if debLevA, every timestep if debLevB
955      * STOP in exf_check_range if 'out of range'
956      * range chosen generous to allow for potential extema
957      TBD: a version with stricter range
958           permitted range would be runtime parameters
959    o GMredi:
960      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
961      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
962      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
963    o GCHEM:
964      - move call to GCHEM_FORCING_SEP, so that it is now called before
965        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
966      - introduced a useGCHEM runtime flag and applied it everywhere.
967      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
968        this flag is now only visible within GCHEM-pkg routines.
969      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
970        be replaced by a 3D array that is computed before thermodynamics; for
971        this, the tracer ID iTracer had to be included into the parameter list
972        of ptracers_forcing
973      - set up forward_step to call gchem_forcing, that will replace
974        gchem_forcing_int in ptracers_forcing
975      - cleaning up
976    o small cleaning of exch2: remove files that are also in eesupp/src
977    
978    checkpoint56
979    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
980    o mnc: cleanup "full" files--fixes out-of-memory problem
981    o ECCO-GODAE
982      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
983      * fully merged and updated from SIO code
984        windstress sign change affects
985        - exf_inscal_[u/v]stress
986        - sign of xx_tau[u/v] adjustments
987        - signs in cost_scat
988      * ctrl_get_gen: avoid update of tau[u/v] for first few days
989      * natl_box_adjoint updated and compressed
990      * 2-level checkpoint switch added
991        (tested in EXP. 1 of natl_box_adjoint)
992      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
993    o SVD
994      * first complete, non-hacked version for SVD calculations
995      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
996        performed via direct access files admtlm_vector.it????
997        (via ctrl_[un]pack)
998      * optimcycle is used for ARPACK iteration counter
999        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
1000      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
1001        and add linear transforms where necessary
1002      * controls are initial/final SST, SSS (can be extended; need to check
1003        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
1004    o mdsio: filename info to both stderr, stdout
1005    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
1006      from sign change
1007    
1008    checkpoint55j_post
1009    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
1010      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1011    o add consistent build directories and .cvsignore files to verification
1012    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
1013    o make all subroutines 30 or less characters in length for certain older
1014      compilers to work (a thorough search only turns up two routines in
1015      pkg/ptracers)
1016    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
1017      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1018    
1019    checkpoint55i_post
1020    o change arrays for total vertical diffusivity (2.D if explicit,
1021      3.D if implicit) ; each ptracer uses its own background value.
1022    o added mnc/NetCDF output capability to ocn_compon_interf
1023      - added bits to verification/cpl_aim+ocn so that it can run on
1024        ITRDA and other clusters without the mpirun "-wd" option
1025    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
1026      configuration
1027    o give MNC the ability to create additional files rather than
1028      exceeding a specified file size limit "MNC_MAX_FILESIZE"
1029      - the default is just less than 2GB which is a practical limit
1030        on many systems
1031    o Compute the non-local term using either KPP vertical diffusivity (=default)
1032       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
1033    
1034    checkpoint55h_post
1035    o add verification test "vermix"
1036    o remove all the *_ioinc flags and replace with the single global
1037      outputTypesInclusive flag
1038    o allow to set a vertical profile of vertical diffusivity for T & S
1039    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
1040    o useMNC moved from data.mnc to data.pkg
1041    
1042    checkpoint55g_post
1043    o Renaming carbon AD experiments to comply with testreport conventions
1044    o Updating adjoint of Held-Suarez hs94.1x64x5
1045    o Fixing directives for non-ECCO forward_step, after ECCO directives
1046      have been fixed to avoid recomp. of do_oceanic_phys
1047      Works well for global_ocean.90x40x15,
1048      but recomp. issue remains for carbon
1049    o Updating adjoint output for natl_box_adjoint after
1050      pkg/ecco has been modified (see taga c55d_post)
1051    
1052    checkpoint55f_post
1053    o rename to timeave_init_fixed
1054    
1055    checkpoint55e_post
1056    o some delicate re-shuffle of store directives to avoid one
1057      extra call of do_oceanic_physics
1058      affects ecco_the_main_loop.F, do_oceanic_physics.F
1059      checkpoint_lev1_directives.h
1060    o NB: this may break global_ocean adjoint temporarily,
1061      but it is clear how to fix it. Will do later, need this now.
1062    
1063    checkpoint55d_post
1064    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1065    o ecco_cost_weights is modified to 1x1 runs
1066    o modifs to allow observations to be read in as
1067      single file or yearly files
1068    o enable to read exf forcing fields as either
1069      single file or yearly files (flag useExfYearlyFields)
1070    checkpoint55d_pre
1071    
1072    o switch between 2-level and 3-level checkpointing
1073    o add ability of MNC to write local and "partial" (eg. 2D slices where
1074      the full 3D field is never actually stored) arrays to NetCDF files
1075      with the correct (that is, the complete multi-dimensional) set of
1076      array indicies
1077      - used in mom_vecinv() to write the diagFreq output
1078      - tested (demonstrated) in verification/aim.5l_cs
1079    o further mnc-ification
1080      - add verification/lab_sea to the list with mnc setups
1081      - fix undefined mnc v-names in cd_code
1082      - add kpp to mnc output (both snapshot and timeave)
1083    o non-hydrostatic code
1084      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1085        in calc_gw.F
1086      - defaults to viscAh
1087      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1088        friction or Leith) in non-hydrostatic mode, as long as there is
1089        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1090    o pkg/cost
1091      extend simple cost functions to treat time mean quantities
1092      (T,U,V) via cost_accumulate_state from cost_tile
1093    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1094        be 2 times larger than the minimum size the advection scheme requires.
1095        now get a perfect conservation of salt in advect_cs test-exp (updated)
1096    o GGL90 (Gaspar's TKE mixed layer)
1097      - add horizontal diffusion of TKE, requires exchanges in
1098        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1099        default. In OPA there is no horizontal diffusion of TKE but the
1100        mixing coefficients are computed from a horizontal average of TKE of
1101        6 points or so. I think that diffusion has a little more physical
1102        justification.
1103      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1104        was in vain)
1105      - mask tke-variable in ggl90_init
1106    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1107    o fix biharmonic diffusion on CS-grid.
1108    o more obcs stuff
1109      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1110        for reading boundary values. This routine is called from
1111        obcs_prescribe_read
1112      - updated obcs_check
1113      - changed sponge layer relaxation parameter units for days to seconds
1114      - turned off sponge layer by default
1115      - changed argument list of OBCS_CALC to myTime+deltaTclock
1116      - fixed about 35 bugs in obcs_external_fields_load
1117    
1118    checkpoint55c_post
1119    o obcs stuff
1120      - new runtime flags useOBCSprescribe, useOBCSbalance
1121      - re-arranged obcs_calc
1122      - moved exf_getobcs to obcs_prescibe_read
1123        obcs_prescibe_read is called after ORLANSKI stuff
1124        and independent of it (executable can contain all).
1125      - updated obcs_check
1126      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1127        These may be necessary only if tangential velocities are
1128        prescribed at OB, not sure, needs testing.
1129    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1130      which simplifies the calls and passes the ifc check-bounds test
1131    
1132    checkpoint55b_post
1133    o add a 2D scalar, Z location, exchange_2 routine.
1134    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1135      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1136      affects advect_cs results (for the wrong reason): update output.txt
1137    o use a more standard discretization for biharmonic viscosity ;
1138     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1139      affects results of dome set-up: update output.txt
1140    o fix gad_advection.F (CubedSphere part), back to version 1.23
1141    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1142    
1143    checkpoint55a_post
1144    o merged code to
1145      * prescribe/read time-dependent open boundaries
1146        (works in conjunction with exf, cal)
1147      * sponge layer code for open boundaries
1148      * each boundary N/S/E/W now has its own CPP option
1149        (healthy for the adjoint)
1150    
1151    checkpoint55
1152    o up-to-date adjoint of previous breaks
1153      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1154      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1155      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1156      - carbon: * remove tr1-related adjoint verification
1157                * add ptracer as control variable
1158    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1159      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1160    
1161    checkpoint54f_post
1162    o in verification/carbin/ remove experiment related to
1163      ALLOW_PASSIVE_TRACER (array tr1 etc)
1164      code_ad/ input_ad/ results_ad
1165    
1166    o add two new packages
1167      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1168        + subject to optimization (memory)
1169      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1170        + subject to reordering (many GOTOs in the original code)
1171        + so far opps is called for every (i,j) point, and then operates in
1172          the vertical; one may want to reorder the scheme in order operate in
1173          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1174          fields)
1175    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1176      - all verification tests compile and run with linux_ia32_g77
1177      - defaults are compatible with current input files--nothing
1178        should change if you were not previously using MNC
1179      - MNC output has been added in numerous places (eg. timeave)
1180        but there are still a few writes not yet do-able with MNC
1181        (this is in progress)
1182      - flags now allow for either/or/both use of MDSIO and MNC and
1183        documentation will soon follow
1184      - numerous small formatting cleanups for ProTeX
1185    o add version info (via BUILD_INFO.h) to MNC and stdout
1186    
1187    checkpoint54e_post
1188    o add two new packages
1189      - pp81 (Packanowski and Philander, 1981), Richardson number and
1190        stratification dependent mixing
1191      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1192      - these scheme operate in a similar manner as KPP (without ghat, of
1193        course), however there is only one diffusivity that is used for both
1194        temperature and salinity (and passive tracers)ç
1195    o add offline package
1196    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1197      provided by Stephanie Dutkiewicz
1198    o genmake2: add ability to search for C compilers and cleanup test output
1199      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1200    
1201    checkpoint54d_post
1202    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1203    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1204      leading to additional shift by 5 days each year of integration
1205       (i.e. leading to considerable offset over the years)
1206    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1207    o start with no AB and no initial filtering (staggerTimeStep):
1208      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1209    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1210      (external loading & cpl import/export stay in forward_step.F)
1211    o update coupling interface to work with new staggerTimeStep
1212    o change MDSIO ptracers_pickup.
1213    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1214    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1215    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1216    
1217    checkpoint54c_post
1218    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1219      this affects (truncation error) output.txt of test-exp:
1220       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1221    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1222    o change Qnet to always be the net heat flux, (+upward).
1223      affects (truncation error) output of natl_box exp.: updated
1224    o define the max number of passive tracers in PTRACERS_SIZE.h
1225    o start to test mnc routinely in exp0
1226    o add sea-ice loading (sIceLoad) as a new forcing field.
1227    
1228    checkpoint54b_post
1229    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1230       impressive on Altix and Opteron systems)
1231    o diagnostics can now write NetCDF files through the mnc package
1232    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1233    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1234    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1235      affects (truncation error) output of lab_sea & natl_box exp.: updated
1236    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1237    
1238    checkpoint54a_post
1239    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1240    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1241    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1242    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1243      + internal_wave (shift in writing cg2d_ini_res)
1244    checkpoint54a_pre
1245    
1246    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1247      - modified verification/lab_sea and natl_box_adjoint accordingly
1248    
1249    checkpoint54
1250    checkpoint53g_post
1251    o prepare splitting of thermodynamics: store convect.counter in common block
1252    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1253      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1254    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1255    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1256    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1257    o restore adjointability
1258    
1259    checkpoint53f_post
1260    o modifications that affect AIM experiment results (update output.txt):
1261      - no advection of S at top interface Nr (pkg/generic_advdiff)
1262      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1263    o AIM pkg:
1264      - include stability function into surf.Flux derivative relative to Tsurf
1265      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1266    
1267    checkpoint53e_post
1268    o merged cylindrical coord configuration
1269    o added rotating_tank experiment
1270    checkpoint53e_pre
1271    
1272    checkpoint53d_post
1273    o faulks upgraded: re-generate output.txt that have changed:
1274       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1275    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1276    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1277    o added Sadourny discretization of Coriolis
1278      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1279      - re-enabled use of omega3 (useAbsVorticity)
1280    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1281      vector-invariant equations
1282      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1283    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1284      hopefully without new bugs
1285      - still to do: biharmonic friction for non-hydrostatic w
1286    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1287    o regenerated output for global_ocean_ebm (using -ieee)
1288    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1289      of mom_common/
1290      - simple re-arrangement of instructions within computing loop
1291    checkpoint53d_pre
1292    
1293    checkpoint53c_post
1294    o new version of coupler for AIM+thSIce and Ocean models
1295     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1296     - land: change Evaporation of snow
1297     - aim with thSIce: fix bug in snow-precip.
1298    o changes to calc_gw.F
1299     - bug fix for w^2 term near the bottom boundary
1300     - (hopefully) improve the lateral slip boundary condtions for use with
1301        partial/looped cells
1302      - because the bug fix changes two verification experiments anyway (exp5
1303        and plume on slope), change the lateral boundary condition from half slip
1304        to the value of no_slip_sides
1305    o ebm package wasnt quite up to the parallel task. Fixed that.
1306    o Adjoint of EBM package + verification
1307      * TLM OK
1308      * ADM not sufficient accuracy yet (needs further testing)
1309    
1310    checkpoint53b_post
1311    o Commiting new energy balance model to repository
1312      * package is pkg/ebm
1313      * verif. is verification/global_ocean_ebm
1314      * references are in ebm_driver.F
1315    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1316    C        Global thermohaline circulation. Part I:
1317    C        Sensitivity to atmospheric moisture transport.
1318    C        J. Climate 12(1), 71-82
1319    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1320    C        Global thermohaline circulation. Part II:
1321    C        Sensitivity with interactive transport.
1322    C        J. Climate 12(1), 83-91
1323    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1324    C        Destabilization of the thermohaline circulation
1325    C        by atmospheric eddy transports.
1326    C        J. Climate 7(12), 1870-1882
1327    o Will need long integration testing.
1328    checkpoint53b_pre
1329    
1330    o created pkg/mom_common in preparation for variable viscosity code
1331    o renamed and split ini_mnc_io
1332    o pkg/land: only liquid water can diffuse or run-off
1333    o AIM using land: soil wetness availability account for snow
1334    o added printMapIncludesZeros to EEPARMS namelist
1335    
1336    checkpoint53a_post
1337    o restore TAMC compatiility for exf_constants.h
1338      (no usage of _d in .h)
1339    o Additional storing in KPP in an attempt to fix
1340      TAMC problem with adjoint of KPP code.
1341      (no success...)
1342      Identical code works fine with TAF.
1343    o Fixed verification/natl_box_adjoint experiments.
1344      Initial conditions for Experiments 4 and 5 are now
1345      set to "SEAICE_initialHEFF=0", which is more reasonable,
1346      and hence gives results closer to that of Experiment 2.
1347      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1348    
1349    checkpoint53
1350    o stable checkpoint with up to date adjoint
1351      TLM tests only run for 1st grdchk at the moment. Its unclear if
1352      this is a code problem or a problem with resetting code for g_
1353      variables that is being autogenerated wrong.
1354      Otherwise:
1355       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1356       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1357         are both still in chaos following their security messes.
1358    
1359    checkpoint52n_post
1360    o various build (mostly genmake2) changes including:
1361      - ability to build/run more easily within Cygwin and MacOS X
1362      - more complicated Makefiles with a stronger dependence on Gnu Make
1363    o pkg/seaice modifications
1364      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1365        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1366        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1367      - changed proxy for geostrophic velocity and updated
1368        verification/lab_sea/results/* accordingly
1369      - removed ADI dynamic solver from pkg/seaice
1370      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1371        they caused a segmentation fault under certain circumstances
1372      - removed unused field WATR
1373    o bug fix in exf-package:
1374      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1375         now reflect that.
1376    o small fixes in the cal-package:
1377      - set reference date to first of January for the 'model'-calendar
1378      - failing of cal_CheckDate in cal_FullDate now actually results in a
1379        warning
1380    o small modifications in exf-package to increase flexibility:
1381      - change climtempfreeze from a constant to a runtime parameter that
1382        is specified in data.exf_clim (default = -1.9)
1383      - introduce runtime parameter windstressmax (default = 2.0) that is
1384        specified in data.exf
1385    o fix in pkg/thsice:
1386      - update Evap (Tsf changes) to be consistent with Latent heat flux
1387      - maintain snow precipitation unchanged (even if Tsf >=0).
1388     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1389    
1390    checkpoint52m_post
1391    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1392      this does not change any of the results, because myIter=0 in swfrac always
1393      lead to jwtype=2 (the default anyway), but the call makes little sense
1394      as a default
1395    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1396    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1397      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1398    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1399    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1400    o extending useSingleCpuIO option to work with new exch2 I/O format
1401      - old-style, missing-tile I/O is still accessible by defining CPP
1402        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1403    o monitor package can write to NetCDF files and/or STDOUT
1404    o fix re-definition bug in MNC_GRID_INIT_ALL()
1405    o doc/api_reference added
1406      - a framework for building an API Reference Manual using all
1407        the "protex" comments embedded in the code
1408      - see pkg/generic_advdiff, pkg/mnc for examples
1409    o MNC:
1410      - make myThid the last argument for all subroutines
1411      - new default for the grid files: NO halos
1412      - add useMNC and other run-time flags
1413      - separate per-file-group handling of the unlimited dimension
1414      - early initialization of MNC w/ flags read at the eeboot stage
1415        and lookup tables set in initialize_fixed
1416      - write all MNC output to a freshly-created directory
1417    o thermodynamics sea-ice (thsice) is now tested with testreport.
1418    o test exp. advect_cs: use the standard cs32 grid ; update output.
1419    o Added functionality to grdchk:
1420      pick global i,j,k position (or nearest wet) where to perform check.
1421    
1422    checkpoint52l_post
1423    o new land formulation:
1424      a) use ground enthalpy as prognostic variable to ensure exact
1425         energy conservation.
1426      b) account for water temperature and for latent heat of freezing
1427         in all processes (rain, run-off, ground storage)
1428      c) compute surface and ground temperature implicitly.
1429    o aim_v23 modification for new land model:
1430      a) Treat separately land / ocean / sea-ice surface fluxes
1431         to allow implicit computation of land & sea-ice surface temp.
1432      b) add snow precipitation.
1433    checkpoint52l_pre
1434    
1435    o fix problem (when 1 tile is empty) in min/max monitor.
1436    o fix bug in timeAve (u,vZetatave in common block)
1437    o no restoring terms under ice for pkg/seaice
1438    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1439    o bug fix for pkg/seaice pickups
1440    o change MNC call locations and add coordinate attributes
1441    o mask vorticity at the corner ; affects global_ocean.cs output
1442    o fix ini_curvilinear_grid ; test CS experiments with mpi
1443    o aim.5l_cs: modify sea-ice fraction input file ; update output
1444    o exf: Adding simple range check routine for exf fields after read
1445    
1446    checkpoint52k_post
1447    o removed top-level directory "diags"
1448      - we migrated these functions to pkg/timeave a long time ago
1449    o fixed bug introduced in pkg/monitor
1450    o accuracy ctrlprec = 32 insuffient for gradient checks using
1451      averaged fields (I/O via cost_averages)
1452      -> use ctrl.h in active_file*.F to control I/O precision.
1453    o paramter list of CALL ADTHE_MAIN_LOOP
1454    o added initial do_the_model_io to ecco
1455    o set all ...Freq to zero after cost_final
1456      taveFreq, dumpFreq, pChkptFreq
1457    o MAIN and ECCO differentiability restored
1458    
1459    checkpoint52j_post
1460    o fix nchklev in tamc.h for global_ocean...
1461    o Bringing flow and store directives up-to-date
1462    o Really weird thing!
1463      call do_the_model_io from the_main_loop with parameters
1464      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1465      TAF places a faulty re-call of initialise_varia
1466      after cost_final call which should not be there!
1467    checkpoint52j_pre
1468    
1469    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1470      error messages
1471    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1472    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1473      debug output
1474    o modfied mdsio_writefield.F to handle non-global files under exch2
1475    o update AIM Cubed-Sphere exp (aim.5l_cs):
1476      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1477    o update AIM Equatorial Channel exp:
1478      use standard aim_v23 pkg and change the SST fields to be more realistic.
1479    o globalFile now works with exch2
1480    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1481      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1482    o limit timeave output for hi-res integrations
1483    
1484    checkpoint52i_post
1485    o removed CPP_EEOPTIONS.h from verification/*/code
1486    o updated the tiling for global_ocean_pressure
1487    checkpoint52i_pre
1488    
1489    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1490      the old pkg/aim).
1491    
1492    checkpoint52h_pre
1493    o shortened offending lines in exch2_send_rx?.template
1494    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1495    o genmake2: add build & execute test for NetCDF code
1496    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1497      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1498    o added useSingleCPUIO flag to monitor.F and mon_out.F
1499    o added temporary hack for sea-ice dynamics on the cube:
1500      metric terms are ignored and it is assumed that
1501      there is no sea-ice on cube faces 1, 2, 4, and 5.
1502    
1503    checkpoint52f_post
1504    o added exch2 cube routines to pkg/exch2
1505    o modified hs94.cs-32x32x5 to use it
1506    o added new grid files to hs94.cs-32x32x5
1507    checkpoint52f_pre
1508    
1509    checkpoint52e_post
1510    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1511      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1512    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1513      to work with implicit vertical advection and AB ;
1514    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1515    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1516     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1517    checkpoint52e_pre
1518    
1519    o fix bug in impldiff when Nr=1 or Nr=2.
1520    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1521    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1522    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1523      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1524  o added exf_offset_atemp for Celsius to Kelvin conversion of atemp  o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1525    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1526    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1527    
1528  checkpoint52d_post  checkpoint52d_post
1529    o re-tiled many expts to allow comparison in multi-processor mode
1530      - updated output accordingly
1531      - changed hs94.128x64x5 to use intial T from file rather than use the
1532        random number generator
1533  o add infrastructure in model routines for fizhi and gridalt packages  o add infrastructure in model routines for fizhi and gridalt packages
1534  o change global_ocean.cs32x15 because of Pb with GM on CS-grid.  o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1535  o changes to permit hi-res, cubed-sphere, configuration  o changes to permit hi-res, cubed-sphere, configuration
