5      ==============================      ==============================
6    
7    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
8      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
9      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
10        to work with SingleCpuIO.
11    o add "_d 0" to real constant of pkg/cfc subroutines ;
12       update exp. cfc_exemple & tutorial_cfc_offline output files.
13    o multi-threading and IO:
14      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
15        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
16      - barrier before and after reading.
17      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
18      - avoid using MDS_WRITELOCAL for LAND pkg output.
19      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
20        common-block variables ; Allows multi-threading with master-thread IO.
21    o change default MAX_NO_THREADS from 32 to 4 ;
22      and stop cleanly when MAX_NO_THREADS is too small.
23    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
24    
25    checkpoint58m_post
26    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
27       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
28    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
29       keep global_ocean.90x40x15 (for AD testing) with former secondary test
30       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
31    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
32        add MITgcm_tutorials (= code + all the tutorials)
33    o ecco, option to compute cost for total ssh (mean+anom)
34    o consistent with addition of ptracer and ssh in pkg/profiles
35    o profiles: adding ptracer and ssh
36    o testreport: change multi-test output-file name
37      (from output.txt.{name} to output.{name}.txt)
38    o profiles: now ok for mutli-tiles case
39    o seaice: add 4 parameters for different advection schemes for area,
40      (effective) seaice thickness, enthalphy, and snow height. Their default
41      is the standard parameter SEAICEadvScheme
42    o calc_gw:
43     - add cosFacU in zonal viscous flux (harmonic.visc.).
44     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
45       of tutorial_plume_on_slope.
46    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
47    o calc_gw: true flux-form, account for horizontal grid spacing.
48      update rotating_tank results, but not plume_on_slope (affected at
49      truncation level, 11 digits).
50    
51    checkpoint58l_post
52    o calc_gw:
53     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
54     - remove side-drag for now (need to fix it); update plume_on_slope results.
55     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
56    o commit code to make SST/SSS weights spatially variable
57      (based on either variable in-situ or variable initial T/S weights)
58    o pkg/ecco:
59      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
60        now based on horizontally varying weights wthetaLev, wsaltLev
61      * cost_averagesflags now returns year indices in addition to day, month
62      * sflux balance is performed on annual basis
63        (sflxumm, sfluxmm2, bal_sfluxmm)
64      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
65        including separate counting and multipliers
66    o pkg/rbcs
67      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
68    
69    checkpoint58k_post
70    o testreport:
71     - always build in dir. "build" (if not there, mkdir build instead of building
72       & running in input)
73     - run in dir run (if it exists), in build otherwise.
74     - call prepare_run (if input/prepare_run exists)
75     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
76    o pkg/exf modifications to interpolation and rotation routines for more
77       reasonable treatment of North Pole singularity: for tracers North Pole
78       value is set to northernmost zonal-mean value, for zonal velocity it is
79       set to zero, and for meridional velocity it is set to northernmost value.
80    o pkg/exf/exf_check_range.F
81     - add tile index to diagnostics and move stop statement to the very
82       end of the routine.
83    o pkg/diagnostics: (diagnostics_main_init.F)
84      define title of isomorphic variables according to the current config.
85    o pkg/thsice with pkg/seaice dynamics:
86    - fix domain of computation (interior only, required for exf) and do exchanges
87    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
88    o towards a standard way of dealing with multi-threading in MONITOR
89      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
90    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
91       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
92    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
93    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
94    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
95       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
96    o tracer advection:
97     - clean-up and simplify calc_common_factors.F
98     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
99       advection subroutine (but still not used within DST advection S/R)
100    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
101    
102    checkpoint58j_post
103    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
104      from file (collects calls previously in FORWARD_STEP)
105    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
106    o adjoint store dir. adjusted accordingly
107    o genmake2
108      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
109    
110    checkpoint58i_post
111    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
112      on wind stress (SEAICEstressFactor defaults to 1.)
113    o Total number of Timers is finite (<=40): comment out 2 non-essential one
114      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
115    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
116      on CS-grid: no longer loosing mass.
117    o exf & curvilinear-grid: no longer modify longitude xC & xG.
118    o pkg/ggl90: fix sloppy output and fix a bug
119    o pkg/seaice: added SEAICEuseEVPpickup parameter
120      - Set to false in order to start EVP solver with
121        non-EVP pickup files when using SEAICEuseEVP
122      - fix sign error in diffusion in seaice_calc_rhs
123    
124    checkpoint58h_post
125    * Modifications for bottom topography control
126      o replace hFacC by _hFacC at various places
127      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
128      o add non-self-adjoint cg2d_nsa
129      o update autodiff support routines
130      o re-initialise hfac after ctrl_depth_ini
131      o works for 5x5 box, doesnt work for global_ocean.90x40x15
132    * Adding verification for 5x5 box (4-layer) bottom topography control
133    
134    checkpoint58g_post
135    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
136       used for mean seasonal cycle, mean diurnal cycle); add an example
137       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
138    o pkg/ggl90:
139      - add parameter (minimum surface kinetic energy)
140      - fix bug (avoiding division by zero)
141    o couple pkg/thsice to pkg/seaice:
142      - modify advection in seaice to accomodate new scalar fields to be advected
143      - only muliDimAdection scheme work with seaice/thsice
144      - mapping of thsice-variables to seaice-variables, back and forth
145      - does not break the verification experiments, but does not give the
146        desired results either
147    o pkg/seaice
148      - make (default) second order advection a bit less confusing?
149    
150    checkpoint58f_post
151    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
152      to pkg/seaice):
153      - new routines thsice_map_exf and thsice_get_exf provide the interface
154      - add an additional formal parameter to thsice_solve4temp
155    o pkg/exf:
156      - add new fields wspeed, snowprecip (to be able to couple to thsice)
157      - correct Stefan-Boltzmann constant
158      - new parameter for longwave surface emittance
159      - separate some stuff from exf_bulkformulae into new routines  
160        exf_radiation, exf_wind
161      - add new parameters and constants: longwave emissivity for ocean, ice
162        and snow, evaporation parameters over ice
163      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
164        either wind from stress or stress from wind
165    o pkg/thSIce:
166    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
167    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
168       and THSICE_CALC_THICKN
169    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
170    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
171      to make debugging easier.
172    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
173    o pkg/bulk_force:
174      - clean-up comments and parameters ;
175      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
176    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
177      generate new output for test-experiment: aim.5l_cs.thSI
178    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
179      testreport accordingly
180    
181    checkpoint58e_post
182    o SEAICE_CGRID adjoint done
183    o R_STAR adjoint implemented.
184      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
185      * need to sort out init. of h0facc, etc.
186    o Make pkg/profile fully independent of ecco,cost, etc. stuff
187      to be able to use it in pure forward.
188    
189    checkpoint58d_post
190    o upgrade simple test-experiment to tutorial example:
191     step.1: duplicate the experiment and (step.2) will remove the old copy.
192      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
193      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
194      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
195      tutorial_global_oce_biogeo    <- copy of dic_example
196      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
197      tutorial_plume_on_slope       <- copy of plume_on_slope
198      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
199      tutorial_global_oce_optim     <- empty for now (David ?)
200      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
201     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
202    o correct a sign problem in cost_scat.F
203    o obcs and ptracers: fix boundary conditions for advections schemes
204      with larger stencil
205    o thsice adjoint: start
206    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
207      completeness
208    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
209      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
210    o ptracers adjoint:
211      * avoid extensive recomputatations
212      * fix missing re-init. of gptr (missed by TAF)
213    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
214      me to turn off the excessive output to STDOUT that this package produces
215    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
216      and add those terms in Vector-Invariant formulation.
217    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
218      if the control period (xx_hfluxperiod etc) is 0
219    o in profiles pkg, clean routines and fix details
220    o in ecco pkg, reading ssh data:
221      fix problem in case the model does not start at iter0=0
222    o fix mnc-pickup/restart for ptracers
223    o new package prifiles:
224      code to compute profile-based cost by Gael Forget
225      (modifs in ecco, ctrl, autodiff)
226    o Benign bug fix in initialization (spotted by M. Mazloff) of
227      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
228    
229    checkpoint58c_post
230    o adjoint: finish NLFS adjoint and provide reference output in
231      verification/global_ocean.90x40x15/results_ad_nlfs
232    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
233      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
234      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
235      with SEAICE_CGRID defined.
236    o move calendarDumps from "data" to "data.cal" and clean-up the code
237      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
238    o add useEXF & useCAL flags (for now, set in hard-coded way)
239    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
240      (were missing in NH mode, and wrong in quasihydrostatic mode).
241      waiting for Chris updated version of calc_gw to add those CALLs.
242    o fix bug in quasihydrostatic S/R ;
243      add a test for this option: global_ocean.90x40x15.qshyd
244    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
245      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
246    o add on/off flag useOffLine for package OFFLINE
247    o seaice:
248      - modify advection so that it works also on the C-grid
249      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
250        problem in multi-tile runs with C-grid
251      - add flags for clipping ice velocities and/or masking solver forcing
252      - fix drag (ocean on ice) formulation and a bug that caused noise in the
253        C-grid solver
254      - added a few comments to seaice_diffusion.F
255      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
256        are now exclusive)
257      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
258        required re-ordering the code a little:
259       + make DAIRN global variable (defined in SEAICE)
260       + move computation of the viscosities eta and zeta into a new separate
261         routine (because I need to recompute them in seaice_ocean_stress.F)
262    
263    checkpoint58b_post
264    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
265      update output.txt of exp. aim.5l_cs.thSI
266    o various mnc cleanups and improvements:
267      + shrink lookup tables by factor of ~4
268      + better error reporting when running out of lookup space
269      + able to handle longer path/file names (up to 500 chars)
270    o adjoint:
271      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
272      - TBD: "hidden" mom_vecinv recomp. in dynamics
273    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
274     (allow to differentiate between forcing components using new integer flags:
275      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
276     and add new flag to put Dissipation tendency out of Adams-Bashforth.
277    o ecco
278      - enable trend removal from SSH anomaly obs.
279    o adjoint
280      - a fix for PmEpR when #undef EXACT_CONSERV
281      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
282      - try to fix "hidden" recomp. in forward_step for NLFS
283        (NLFS seems broken sometimes after I checked it in)
284    o seaice:
285     - add c-grid version of the dynamic solver:
286       + three new routines that are the c-grid substitute lsr, dynsolver
287         and ostres
288       + put a few fields that were local to dynsolver into global common
289         blocks, so that I can move the computation of stresses etc into
290         seaice_lsr (saves coding but may break the adjoint).
291     - replace more hardwired parameters by runtime parameters
292     - add ice masks that mask the rhs of the implicit solvers where there
293       is no ice (commented out in seaice_dynsolver, because i am not sure
294       if this works properly), eventually this should replace the clipping
295       of ice velocities in seaice_dynsolver to +/-40cm/s.
296    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
297      include it only where its needed
298    o move balancing of fluxes before the call of external_forcing_surf
299    o seaice:
300      - correct units of turning angles (now they are really in degrees)
301      - move computation of GWATX/Y out of main routine into dynsolver
302      - initialize GWATX/Y in seaice_init
303    o Apply mask on Fresh-Water flux (needed for SSH forcing).
304      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
305    o seaice: add runtime flags for turning angles (default to zero)
306    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
307      and trend from exf forcing and ctrl control adjustments
308    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
309      (since checkpoint57x_post)
310    o change the default rotation period to 86164.s = the Earth rotation
311    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
312      and based on a reference stratification. Tested within hs94.cs-32x32x5.
313    o seaice advection: add code for choosing between the default (2nd order
314      central differences) and multiDim advection schemes provided by
315      pkg/generic_advdiff
316    o seaice:
317      - removed all references to SEAICE_GRID.h fields from
318        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
319        (cubed-sphere configuration will change a little)
320      - grid computations in seaice_init are obsolete now.
321      - cleaned up code a little so that is easier to read (hopefully).
322      - added new (better?) discretizations of default advection and diffusion
323        (turn on with SEAICEuseFluxForm)
324      - replace 1 in 3d global fields by kSurface in growth.F
325      
326    checkpoint58a_post
327    o seaice:
328      - bug fix in advect.F
329    o shelfice:
330      - separate shelfice load anomaly from pload (breaks with time
331        dependent forcing), => introduce constant field shelficeLoadAnomaly.
332        Its default is 0., but it may be computed more cleverly from (unknown)
333        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
334        done offline. A good approximation of the pressure load anomaly is
335        necessary to avoid large initial adjustment processes underneath
336        deep-reaching shelfice.
337      - small fix in ISOMIP shelfice_thermodynamics
338      - add more sophisticated thermodynamics of Hellmer (1989), this is
339        now the default
340      - give a few constants more intuitive names
341    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
342      if bulk formulae are used in long integration (especially EmPmR). Turn
343      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
344      if balancePrintMean, the imbalance that is substracted is printed to
345      STDOUT.
346    o fix bug (typo) in obcs_apply_eta.F
347    o add a new package shelfice which enables us to model the circulation
348      underneath shelf-ice with draughts of hundreds of meters.
349     - works
350     - to do: + include improved thermodynamics
351              + check whether kSurfC (from model/inc/SURFACE.h) can be used
352                instead of new field kTopC
353              + can we use topoFile, Ro_surf and existing code in ini_depth.F
354                instead of new field R_shelfIce and new code in ini_depth.F
355                and ini_mask_etc.F?
356              + adjust vertical mixing schemes?
357    o seaice pkg:
358     - add a cpp-flag to include a simple formula for a salinity dependent
359       freezing point of sea water at the surface
360     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
361       meridional stresses are now different (and hopefully correct)
362    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
363       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
364       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
365    o pkg/diagnostics: add options and parameters for regional-statistics
366       diagnostics ; define regions by reading a region-mask from a file
367       (might add other options later)
368    o pkg/bulk_force:
369     - add option and parameters to use AIM surface-flux formulae.
370     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
371       others forcing fields (defined in PARM05, parameter file "data") are loaded
372       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
373     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
374     - use the right EXCH call for uwind,vwind (to work on CS-grid).
375     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
376       and parameters (note: calcWindStress replaces .NOT.readwindstress).
377     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
378    
379    checkpoint58
380    o add "--embed-source" option to genmake2 which, when the supporting
381      tools can be compiled (as determined by genmake2) will turn on the
382      embed_files package which then embeds the entire MITgcm source code
383      (*.[fFhc] + Makefile) used for the build within the executable
384      - requested by CNH but off by default
385      - adds a paltry <9MB to the mitgcmuv executable in most cases
386      - only writes the output when useEMBEDSRC in eedata is true
387    o clean up 3-dim. relaxation codes:
388      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
389      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
390      * Thanks to Tom Haine for testing!
391    
392    checkpoint57z_post
393    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
394      affects output (@ truncation level) of exp. plume_on_slope ; updated.
395    o fix the pickup behavior for obcs in combination with ptracers
396    o fix a bug in ptracers_external_fields_load
397    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
398      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
399    o transfered surface NH pressure to eta field (if exactConserv).
400    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
401         and update lab_sea output.txt file.
402    o completing 3-dim. relaxation code: additional term
403         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
404      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
405      * At compile time, in "EXF_OPTIONS.h" set
406          #define  ALLOW_CLIMTEMP_RELAXATION
407          #define  ALLOW_CLIMSALT_RELAXATION
408      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
409          tauThetaClimRelax3Dim = 15552000.0,
410          tauSaltClimRelax3Dim  = 15552000.0,
411      * 3 cases:
412          1) Use a constant-in-time 3-dim. field
413          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
414          3) Real-time relax. to time-evolving prescribed field
415    o Adding Laplacian-type smoothness constraint on
416      initial and boundary (forcing) controls (ic, bc)
417      * enable at compile-time via
418        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
419      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
420      * Absolute scale somewhat unclear so far
421      * no area weighting was included since no other cost term does so far
422    
423    checkpoint57y_post
424    First step for a NLFS adjoint
425    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
426    o new init. routines for calc_r_star, calc_surf_dr
427    o still need to deal with ini_masks_etc
428    o testreport seemed happy
429    checkpoint57y_pre
430    
431    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
432    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
433    o add new offset feature to offline pkg (plus minor cleanup)
434    o cfc fixes for final year of integration
435    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
436      be in GCHEM_OPTIONS).
437    
438    checkpoint57x_post
439    o fix testreport Pb in multiple test experiment.
440    o cleanup our namelist syntax in verification:
441      - make it more F95 standards compliant (some work still needed)
442      - allows the vast majority of our tests to work with gfortran
443    o Non-Hydrostatic:
444     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
445     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
446    o Allow to apply AB on T,S rather than on AB(gT,gS):
447     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
448     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
449       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
450     - need a "clever" read_pickup to restart from the other AB formulation
451    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
452    o remove some unused variables (reduces number of compiler warnings)
453    o adjoint
454      * Disable useVariableViscosity for adjoint for time being
455        (there are a number of extensive recomputations)
456      * Initialize certain variables needed for adjoint
457    
458    checkpoint57w_post
459    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
460                 fix the singleCpuIO RS version of MDSWRITEFIELD
461       and add a WARNING if using globalFiles=T with multi-processors.
462    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
463      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
464    o tracer advection scheme:
465      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
466       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
467       was not very convenient).
468      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
469       (further tests needed for the implicit DST & Flux-Limiter schemes).
470    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
471      and sRef for convenience, handy, when you want to initialize
472      ptracers in a large domain with a constant non-zero value. Also,
473      untangle ptracers_init.F a little.
474    
475    checkpoint57v_post
476    o change dome exp. to use variable viscosity in side-drag terms.
477    o remove all the files from the cfc_offline test since they are now
478      incorporated into tutorial_cfc_offline which has been producing
479      identical results for a few days of testing
480    o add new parameter: sideDragFactor to enable half-slip-side BC
481      and change side-drag S/R to use viscosity from mom_calc_visc
482      (can switch back by setting sideDragFactor=0.); affects results at
483      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
484       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
485    o vorticity & strain are now computed without masking, to account for
486      no-slip-side BC in variable viscosity calculation ; mask is applied
487      anyway later on, before computing advection/coriolis terms.
488    o modify exp4 to test new obcs support for reading from external files
489      and for passive tracers
490    o fix behavior of ptracers_monitor when monitor output is written to a
491      netcdf-file; still not independent of monitor.F (writes in the same
492      file).
493    o change default value of tRef (put a uniform, meaningful value for ocean
494      & atmos) and initialize sRef (was missing, as Martin mentioned).
495    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
496      to be proportional to enstrophy dissipation length.  Thus,
497       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
498      This is now consistent with Smagorinsky and with the manual.
499    
500    checkpoint57u_post
501    o OBCS and PTRACERS: add open boundary support for passive tracers
502      - either use homogenous (pseudo) v.Neumann conditions or prescribe
503        OB-values from file; this is not different from the way theta and salinity
504        are treated
505      - however, Orlanski-radiation conditions are not supported, and the model
506        will stop if you use pTracers and Orlanski at the same time.
507      - beefed up the rountine obcs_external_fields_load: now only those open
508        boundary values are overwritten with values from files for which there
509        are really files, otherwise the OB-fields remain untouched. This makes
510        it possible to use different OBs at different ends of the domain (as
511        with EXF)
512    o reduce number of exch calls in shap_filt (s2).
513    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
514      truncation level) 4/5 MLAdjust test results (11&12 digits match).
515    
516    checkpoint57t_post
517    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
518    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
519      same truncation, independent of the face number: affects affects several
520      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
521    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
522      note that biharmonic viscosity + no-slip was not tested in any experiment.
523    o fix bug in non-linear free-surf side-drag ; generate new output for
524      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
525    o make mnc honor the writeBinaryPrec flag for most kinds of output
526    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
527    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
528      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
529    o add brackets in multi-terms sum to get same truncation, independent of
530      the face number (manage to get exactly same value of gU,gV at the cs-edge)
531      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
532    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
533      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
534      a maximum grid-scale Reynolds number.  Also, changes all length calculations
535      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
536      Suggested values of viscosity parameters found in mom_calc_visc.
537      Many new viscosity diagnostics available.
538    
539    checkpoint57s_post
540    o Add clearing-house for viscosity calculations, mom_calc_visc and
541      correct numerous bugs in LeithD and Smagorinsky discretizations.  
542      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
543      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
544      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
545      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
546      The Strain-Tension form is now called with useStrainTensonVisc=.true.
547      ViscAhStrain and viscAhTension are now retired.
548    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
549    o In response to JMC's bug report, genmake2 now ignores any soft-links
550      that it finds in the *current* directory when searching for files.
551      Soft-links found in any other source directories will still work as
552      they did before.
553    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
554      a C routine to unlimit the stack size
555    o mnc-ify pkg/aim snapshot vars
556    o mnc-ify pkg/land as requested by Daniel
557    o various changes to mnc including:
558      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
559      - output can now be grouped so that all files within a group
560          change the ITER portion of their names in lock-step together
561      - can now read ("global") PER-FACE (in addition to PER-TILE) files
562          and works with both EXCH1 and EXCH2 (but needs more testing)
563      - writing works for all verification test cases w/ g77 on Linux
564    
565    checkpoint57r_post
566    o make MNC variable initialization happen earlier
567    o add diagnostics for (almost) each term of the momentum Eq.
568    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
569    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
570    o remove MINIMAL_TAVE_OUTPUT option ;
571      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
572    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
573      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
574    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
575    o add time-dependent SST, SSS control
576    o cost terms in ecco/ modularized (new cost_generic.F)
577    o cost_averages routines are modularized (new cost_averagesgeneric.F)
578    o new infrastructure for seaice model vs. obs misfits in seaice/
579      * driver from the_main_loop.F is seaice_cost_driver.F
580      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
581      * gradient check in Exp. 6a of natl_box_adjoint/
582    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
583      (see README file)
584    
585    checkpoint57q_post
586    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
587    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
588      - bug was reported by Jean-Michel and Ian Fenty
589    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
590      update exp. cpl_aim+ocn output.
591    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
592      Needed for high-res. runs with large global files
593      to be able to limit tapelev size
594    o Changed some tests for adjoint:
595      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
596      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
597      * global_ocean.90x40x15/ back to default 3-level checkpointing
598    o Modifications to enable scripted COMMON to MODULE conversion
599      * verification/OpenAD/code/ has necessary scripts and description;
600      * converts, compiles and runs successfully;
601    
602    checkpoint57p_post
603    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
604    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
605      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
606    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
607    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
608      (was already the case for dissipation with mom_vecinv,
609       and also the case for grad.PhiHyd when staggered-timeStep)
610      This will allow to put dissipation out-off the AB time-stepping.
611     Unfortunately, affects truncation error. Update output of exp. that "fails"
612      (cg2d matching number) and leave the others for later: front_relax(10),
613      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
614      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
615    
616    checkpoint57o_post
617    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
618      (2) its ready to be documented during the 20050801 DocFest
619    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
620      for ideal_2D_oce and lab_sea on linux_ia32_g77
621    o set to #undef CTRL_SET_OLD_MAXCVARS_30
622      in global1x1_tot/code_seaice_adj to access indices 32, 33
623      (worth another tag)
624    
625    checkpoint57n_post
626    o adding precip control xx_precip 32
627    o adding swflux control xx_swflux 33
628    o Replacing 10 forcing penalty cost routines by 1 generic.
629    o Implementing partitioning in time-mean and variable adjustment
630      for atmos. state.
631    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
632    o in natl_box_adjoint:
633      * updated exp 1 to 10
634        (but does not have time-mean vs. variable split results yet)
635    o updated global1x1/*_seaice_adj/
636      to incorporate latest changes
637    o enable useSingleCpuIO for mdsio vector routines
638      (applies in particular to tapelev I/O)
639    o removed inefficient K-loop in all active_file*control*.F
640    
641    checkpoint57m_post
642    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
643      and advect_cs (use EXCH-2 and standard cs-32 grid files).
644    o pkg/exch2: filling of face-corner halo regions is optional
645      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
646    
647    checkpoint57l_post
648     tag before updating tutorials (pre-release-2)
649    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
650       for output and interpolation of input fields onto model grid)
651    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
652       Affects results of exp. rotating_tank ; update output.txt.
653    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
654          and taking the square quantity and/or using a fraction-weight field.
655    o fix aim_diagnostics_init.F mate numbers.
656    o add mnc output capability to diagnostics/diagstat and update
657      our cvsignore files for the ACSII output generated
658    
659    checkpoint57k_post
660    o lab_sea now uses diagnostics package and provides a suite of
661      new EXF diagnostics output.
662    
663    checkpoint57j_post
664    o exf
665      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
666        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
667        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
668      * extended diagnostics output
669        - now includes all EXF variables
670        - hs, hl moved to common block
671        - separate S/R for diagnostics, called after ctrl vector is added
672        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
673        - EXFqnet contains true Qnet (i.e. includes qsw)
674      * updated verif. lab_sea, global_with_exf
675      * Rearranging hflux (exf_mapfields -> exf_getforcing)
676        to ensure that diagnostics sees a true EXFqnet
677    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
678    o diagnostics pkg: change pointers so that 1 diagnostic can be used
679      several times with different frequencies.
680    o mnc-ify the thsice package as requested by Daniel Enderton
681      - the monitor--MNC output needs work
682      - many attributes need to be added (most are currently blank)
683    o mnc-ify theaim_v23 package as requested by Daniel Enderton
684      - many attributes need to be added (most are currently blank)
685    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
686    o add Sadourny like discretization to the 4th.O vorticity advection scheme
687    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
688      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
689         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
690    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
691     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
692    
693    checkpoint57i_post
694    o Diagnostics package was changed: diagnostic allocation is now deactivated
695      by setting an empty file name in the namelist (used to be by setting 0 frequency)
696    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
697      add 1rst Order upwind vertical Shear.
698    o add a quick fix for A/B checkpointing in OFFLINE mode
699    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
700      end-run around the C/Fortran linking horror in eesup/src/timers.F
701    o added pkg/runclock: allows user to terminate run based on wall clock
702    o added non-hydrostatic scaling parameter: nh_am2
703    o pkg/my82: futile attempt to make results compiler-independent by adding
704      some "_d 0", etc. no effect.
705    o for mnc output, fill the 'T' coordinate var with myTime and create a
706      separate 'iter' variable for iteration count
707    o pkg/diagnostics:
708      add new capability: output of Global/Regional & per-level statistics ;
709      tested against monitor output (including land & thSIce) on various exp.
710    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
711    
712    checkpoint57h_done
713      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
714      data.diagnostics, data.gchem, data.ptracers) is done.
715    
716    o pkg/diagnostics: prepare for Global/Regional statistics.
717      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
718    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
719      and rename it: DIFFERENT_MULTIPLE
720    
721    checkpoint57h_post
722    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
723    o pkg/diagnostics: change output frequency, now in seconds (instead
724      of Nb of iterations). This requires to change data.diagnostics.
725    checkpoint57h_pre
726    
727    o in mnc, let the user create the output dir if both mnc_outdir_date
728      and mnc_outdir_num are false
729    o add fflags() to pkg/diagnostics which allows one to specify, on a
730      per-file basis, the file precision [default behavior is unchanged]
731    o added diagnostics to pkg/kpp, including computation of mixed layer
732      depth based on a temperature/density criterion
733    o updated verification/natl_box to test the new pkg/kpp diagnostics
734    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
735    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
736    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
737      not mnc -- this mistake was found by JMC and is now corrected
738    
739    checkpoint57g_post
740    o add Adams-Bashforth 3rd Order time stepping:
741      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
742      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
743    checkpoint57g_pre
744    
745    o make lambda[Theta,Salt]ClimRelax spatially varying
746      (default remains spatially uniform constant based on tau)
747    o added new control variables
748      * init. uVel, vVel, etanN
749      * lambda[Theta,Salt]ClimRelax
750    o separate masks used for ctrl_pack/unpack 'from write_grid' output
751      (suggested by G. Forget)
752    
753    checkpoint57f_post
754    o add parameter "baseTime" = model base time = time at iteration zero
755      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
756      account for baseTime shift
757    o move Coriolis arrays from PARAMS.h to GRID.h
758    checkpoint57f_pre
759    
760    o mnc-ifying the seaice package
761    o introduced an alternative length scale calculation for use in the limiting
762      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
763    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
764    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
765      as well as grad(vort3).  Made it compatible with both approximate form
766      for the cubed sphere and full form of these gradients.  Added flag
767      useFullLeith to select between approximate and full form.  
768    o add "d0" in getcon.F to reduce differences between compilers/platforms
769      update output.txt of exp. fizhi-gridalt-hs
770    o change port_rand funtion to allow to set the seed.
771    o fix obscure MNC bug involving conversion between reals and integers
772      - it caused no problems with certain (eg. gcc, ifc) compilers but the
773        new version is now more standards-compliant
774    o adjoint-related modifications
775      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
776      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
777      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
778    
779    checkpoint57e_post
780    o Adding eddy stress controls a la Ferreira et al.
781    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
782    
783    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
784      update output.txt of exp. fizhi-gridalt-hs
785    o add more "Z" dimensions and associated coordinate vars to MNC
786    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
787    o parameter calendarDumps: when set, approximate months (30-31 days) and years
788      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
789      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
790      months and years.  Requires pkg/cal.
791    o diagnostics: add pickup functionality
792      - off by default for backwards compatibility
793      - current version only uses MDSIO -- MNC will be added
794    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
795    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
796    
797    checkpoint57d_post
798    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
799    o modify verification/ideal_2D_oce so that it tests the creation of mnc
800      output from the diagnostics package
801    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
802    o make genmake2 more portable by using ".$FS" instead of ".f" for more
803      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
804    o add coordinate variables to the MNC output from the diagnostics package
805    o change MNC-flags default value: true when useMNC=TRUE
806    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
807      the ability (off by default) to read the grid information using MNC
808    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
809    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
810    o do snap-shot diagnostics at the middle of the time-interval (instead of
811      at the end).
812    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
813      new test for AIM with thSIce + slab-ocean
814    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
815    o move state variable diagnostics to the beginning of the time step ;
816      (note: still needs some work specially for snap-shot diagnostics)
817      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
818    
819    checkpoint57c_post
820    o Change testing option (-ieee) to get closer agreement between g77 & ifort
821    o generate new output.txt files on faulks with g77 & the new -ieee option
822    checkpoint57c_pre
823    
824    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
825      update output.txt of exp. global_ocean.90x40x15
826    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
827      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
828    o add saltFlux(+File) forcing capability with periodicExternalForcing
829    o allow to use pkg diagnostics for GM-Redi & ThSIce output
830    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
831    o improvements for the MNC output from DIAGNOSTICS:
832      - correct handling of the unlimitied dimension
833      - all dims now have associated coordinate variables
834      - variables located at U, V, and Corner ("Z") points are now written
835        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
836        *all* data points are output
837    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
838    o added pkg/seaice/seaice_monitor.F
839    o mdsio_readfield.F can now read files visible only to master MPI process.
840    o pkg/seaice: some test code for ice-modified ocean stress
841    o exf_getffields interpolation defaults to bilinear for all scalar forcing
842      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
843      spurious negative numbers for precipitation and humidity.  Will cause
844      some small numerical differences for integrations using pkg/exf/exf_interp.F.
845    o pkg/ctrl/
846      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
847        May be enabled via doPackDiag
848      *  introduce z-scaling of
849         + gradient (doZscalePack) and
850         + control (doZscaleUnpack)
851    o pkg/mdsio/
852      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
853      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
854    
855    checkpoint57b_post
856    o simplify options in diagnostics_fill arguments (remove weird combinations)
857    o fix MNC coordinate variables so that they now contain per-face index
858      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
859      general, EXCH2 grids are only aligned to a "local" coordinate system
860    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
861    o Implement instantaneous output within pkg diagnostics:
862      setting a negative frequency in data.diagnostics produces
863     "snap-shot" output (as opposed to time-average if freq > 0)
864    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
865      NOTE: change ptracer diagnostics name: use 2 characters to work with
866            more than 9 tracers. Add also diagnostics of advect & diffus flux.
867    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
868      becomes the coordinate variable for the 'T' dimension
869    o add CF-style coordinate variables to MNC
870      - just a first cut:  numbers are meaningless on the cubesphere and
871        missing along the T axis but otherwise it works!
872    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
873    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
874    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
875      this is based directly on what the model compute, so that the content of
876      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
877    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
878    o clean up build options files for SunOS, in particular
879      - remove -traditional from xmakedepend
880      - change -xarch=v9 to -xarch=native for f77
881      - restore use of make (not gmake)
882      - add CC=gcc if using g77
883    o changes per discussion of AM, JMC, & EH3 today:
884      - move redundant "grid" variables out of "state" -- in preparation of
885        creating proper CF-style coordinate variables and in recognition
886        that any/all grid variables can be easily copied (eg. w/NCO) from
887        the grid files into any of the other NetCDF files
888      - *always* output grid variables with MDSIO (this will eventually be
889        changed)
890      - output MNC grid file if useMNC is true
891    o every instance of _END_MASTER() has been found and replaced with
892      _END_MASTER( myThid ) in order to satisfy certain picky Sun
893      preprocessors
894    o re-arrange diagnostics pkg initialisation:
895     - allow each package to extend the available diagnostics list
896     - add some checking and fix small problems (multi-threaded, ...)
897     - new S/R diagnostics_fill (replace fill_diagnostics):
898       look through the short list of active diag. (instead of the long list)
899       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
900    
901    checkpoint57a_post
902    o this set of changes restores TAMC compatibility
903      tested for global_ocean.90x40x15 adjoint on trough
904      (what a pain)
905    
906    checkpoint57a_pre
907    o some modifs in tools/build_options for sunos
908    o call ctrl_pack for ctrl at end for optimcycle=0
909    
910    checkpoint57
911    o add horizontal bi-harmonic viscosity for vertical velocity
912      - new parameter viscA4W (defaults to viscA4)
913      - affects only non-hydrostatic code
914      - to be done: no-slip lateral boundary conditions
915    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
916    o implement Implicit Vertical advection for pTracers
917    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
918      (implemented also for implicit vertical diffusion & advection)
919    o OBCS: extend application of tracer open boundary conditions
920      to a strip beyond the boundary of width Olx/Oly
921    o add call monitor to TAF set of required calls (flow directives)
922      and include in natl_box_adjoint
923    o untangle a few ifdefs related to cost, ctrl, autodiff
924      untangel a few ALLOW_ECCO_OPTIMIZATION
925    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
926      (theta2, salt2 in ecco_cost_weights)
927    
928    checkpoint56c_post
929    o OBCS as control variables
930      - update ctrl_ad_diff.list, obcs_ad_diff.list
931      - remove balance of obcs controls from default
932      - fix index bug nobcs in ctrl_init
933      - fix dummy fields filen in ctrl_pack
934      - add dummy weights for obcs
935    o lsopt: comment out fort.94 output
936    o optim:
937      - remove unnecessary header files
938      - adjusted namelists
939      - add xerbla.F to Makefile
940    o exf:
941      - multiple modifications of exf_check_range
942      - unit change in exf_init_runoff from [m/year] to [m/s]
943    o mdsio:
944      - i/o-vector change debugLevel from debLevA to debLevB
945    
946    checkpoint56b_post
947    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
948      is called from DO_THE_MODEL_IO
949      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
950      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
951      - clean up PTRACERS_WRITE_TIMEAVE a little
952    o add another verification experiment that tests both the cfc-pkg and
953      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
954      reactive tendencies treated inline with regular timestepping
955    o testreport previously did a lousy job of comparing small numbers, so
956      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
957      implemented in the little c-progam tmp_cmpnum.c which is embedded in
958      testreport.
959    o ptracers_monitor: bug fix for MPI
960    
961    checkpoint56a_post
962    o GCHEM: finish reorganizating the package
963      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
964        (introduces another 3D-array for each passive tracer, but only if
965        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
966        gchemTendency is not needed because the timestep is done separately)
967      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
968      - GCHEM is now---more or less cleanly---separate from PTRACERS
969      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
970        so clear to me how that should be done in a general way.
971    o CFC: improve formatting of output in CFC_ATMOS
972    o PTRACERS:
973      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
974        that ALL experiments with ptracers enable can be checked. This makes
975        GCHEM_MONITOR obsolete.
976      - include a runtime parameter PTRACERS_monitorFreq that defaults to
977        monitorFreq
978      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
979    o add PTRACERS (PTR0[1-5]) to testreport output
980    o exf_check_range:
981      * default changed to .TRUE.
982      * will check values for niter0 if debLevA, every timestep if debLevB
983      * STOP in exf_check_range if 'out of range'
984      * range chosen generous to allow for potential extema
985      TBD: a version with stricter range
986           permitted range would be runtime parameters
987  o GMredi:  o GMredi:
988    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
989    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.

996        this flag is now only visible within GCHEM-pkg routines.
997      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
998        be replaced by a 3D array that is computed before thermodynamics; for
999        this, the tracer ID iTracer had to be included into the parameter list
