5      ==============================      ==============================
6    
7    o pkg/diagnostics: (diagnostics_main_init.F)
8      define title of isomorphic variables according to the current config.
9    o pkg/thsice with pkg/seaice dynamics:
10    - fix domain of computation (interior only, required for exf) and do exchanges
11    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
12    o towards a standard way of dealing with multi-threading in MONITOR
13      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
14    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
15       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
16    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
17    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
18    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
19       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
20    o tracer advection:
21     - clean-up and simplify calc_common_factors.F
22     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
23       advection subroutine (but still not used within DST advection S/R)
24    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
25    
26    checkpoint58j_post
27    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
28      from file (collects calls previously in FORWARD_STEP)
29    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
30    o adjoint store dir. adjusted accordingly
31    o genmake2
32      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
33    
34    checkpoint58i_post
35    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
36      on wind stress (SEAICEstressFactor defaults to 1.)
37    o Total number of Timers is finite (<=40): comment out 2 non-essential one
38      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
39    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
40      on CS-grid: no longer loosing mass.
41    o exf & curvilinear-grid: no longer modify longitude xC & xG.
42    o pkg/ggl90: fix sloppy output and fix a bug
43    o pkg/seaice: added SEAICEuseEVPpickup parameter
44      - Set to false in order to start EVP solver with
45        non-EVP pickup files when using SEAICEuseEVP
46      - fix sign error in diffusion in seaice_calc_rhs
47    
48    checkpoint58h_post
49    * Modifications for bottom topography control
50      o replace hFacC by _hFacC at various places
51      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
52      o add non-self-adjoint cg2d_nsa
53      o update autodiff support routines
54      o re-initialise hfac after ctrl_depth_ini
55      o works for 5x5 box, doesnt work for global_ocean.90x40x15
56    * Adding verification for 5x5 box (4-layer) bottom topography control
57    
58    checkpoint58g_post
59    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
60       used for mean seasonal cycle, mean diurnal cycle); add an example
61       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
62    o pkg/ggl90:
63      - add parameter (minimum surface kinetic energy)
64      - fix bug (avoiding division by zero)
65    o couple pkg/thsice to pkg/seaice:
66      - modify advection in seaice to accomodate new scalar fields to be advected
67      - only muliDimAdection scheme work with seaice/thsice
68      - mapping of thsice-variables to seaice-variables, back and forth
69      - does not break the verification experiments, but does not give the
70        desired results either
71    o pkg/seaice
72      - make (default) second order advection a bit less confusing?
73    
74    checkpoint58f_post
75    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
76      to pkg/seaice):
77      - new routines thsice_map_exf and thsice_get_exf provide the interface
78      - add an additional formal parameter to thsice_solve4temp
79    o pkg/exf:
80      - add new fields wspeed, snowprecip (to be able to couple to thsice)
81      - correct Stefan-Boltzmann constant
82      - new parameter for longwave surface emittance
83      - separate some stuff from exf_bulkformulae into new routines  
84        exf_radiation, exf_wind
85      - add new parameters and constants: longwave emissivity for ocean, ice
86        and snow, evaporation parameters over ice
87      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
88        either wind from stress or stress from wind
89    o pkg/thSIce:
90    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
91    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
92       and THSICE_CALC_THICKN
93    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
94    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
95      to make debugging easier.
96    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
97    o pkg/bulk_force:
98      - clean-up comments and parameters ;
99      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
100    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
101      generate new output for test-experiment: aim.5l_cs.thSI
102    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
103      testreport accordingly
104    
105    checkpoint58e_post
106    o SEAICE_CGRID adjoint done
107    o R_STAR adjoint implemented.
108      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
109      * need to sort out init. of h0facc, etc.
110    o Make pkg/profile fully independent of ecco,cost, etc. stuff
111      to be able to use it in pure forward.
112    
113    checkpoint58d_post
114    o upgrade simple test-experiment to tutorial example:
115     step.1: duplicate the experiment and (step.2) will remove the old copy.
116      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
117      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
118      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
119      tutorial_global_oce_biogeo    <- copy of dic_example
120      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
121      tutorial_plume_on_slope       <- copy of plume_on_slope
122      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
123      tutorial_global_oce_optim     <- empty for now (David ?)
124      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
125     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
126    o correct a sign problem in cost_scat.F
127    o obcs and ptracers: fix boundary conditions for advections schemes
128      with larger stencil
129    o thsice adjoint: start
130    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
131      completeness
132    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
133      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
134    o ptracers adjoint:
135      * avoid extensive recomputatations
136      * fix missing re-init. of gptr (missed by TAF)
137    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
138      me to turn off the excessive output to STDOUT that this package produces
139    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
140      and add those terms in Vector-Invariant formulation.
141    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
142      if the control period (xx_hfluxperiod etc) is 0
143    o in profiles pkg, clean routines and fix details
144    o in ecco pkg, reading ssh data:
145      fix problem in case the model does not start at iter0=0
146    o fix mnc-pickup/restart for ptracers
147    o new package prifiles:
148      code to compute profile-based cost by Gael Forget
149      (modifs in ecco, ctrl, autodiff)
150    o Benign bug fix in initialization (spotted by M. Mazloff) of
151      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
152    
153    checkpoint58c_post
154    o adjoint: finish NLFS adjoint and provide reference output in
155      verification/global_ocean.90x40x15/results_ad_nlfs
156    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
157      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
158      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
159      with SEAICE_CGRID defined.
160    o move calendarDumps from "data" to "data.cal" and clean-up the code
161      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
162    o add useEXF & useCAL flags (for now, set in hard-coded way)
163    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
164      (were missing in NH mode, and wrong in quasihydrostatic mode).
165      waiting for Chris updated version of calc_gw to add those CALLs.
166    o fix bug in quasihydrostatic S/R ;
167      add a test for this option: global_ocean.90x40x15.qshyd
168    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
169      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
170    o add on/off flag useOffLine for package OFFLINE
171    o seaice:
172      - modify advection so that it works also on the C-grid
173      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
174        problem in multi-tile runs with C-grid
175      - add flags for clipping ice velocities and/or masking solver forcing
176      - fix drag (ocean on ice) formulation and a bug that caused noise in the
177        C-grid solver
178      - added a few comments to seaice_diffusion.F
179      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
180        are now exclusive)
181      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
182        required re-ordering the code a little:
183       + make DAIRN global variable (defined in SEAICE)
184       + move computation of the viscosities eta and zeta into a new separate
185         routine (because I need to recompute them in seaice_ocean_stress.F)
186    
187    checkpoint58b_post
188    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
189      update output.txt of exp. aim.5l_cs.thSI
190    o various mnc cleanups and improvements:
191      + shrink lookup tables by factor of ~4
192      + better error reporting when running out of lookup space
193      + able to handle longer path/file names (up to 500 chars)
194    o adjoint:
195      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
196      - TBD: "hidden" mom_vecinv recomp. in dynamics
197    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
198     (allow to differentiate between forcing components using new integer flags:
199      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
200     and add new flag to put Dissipation tendency out of Adams-Bashforth.
201    o ecco
202      - enable trend removal from SSH anomaly obs.
203    o adjoint
204      - a fix for PmEpR when #undef EXACT_CONSERV
205      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
206      - try to fix "hidden" recomp. in forward_step for NLFS
207        (NLFS seems broken sometimes after I checked it in)
208    o seaice:
209     - add c-grid version of the dynamic solver:
210       + three new routines that are the c-grid substitute lsr, dynsolver
211         and ostres
212       + put a few fields that were local to dynsolver into global common
213         blocks, so that I can move the computation of stresses etc into
214         seaice_lsr (saves coding but may break the adjoint).
215     - replace more hardwired parameters by runtime parameters
216     - add ice masks that mask the rhs of the implicit solvers where there
217       is no ice (commented out in seaice_dynsolver, because i am not sure
218       if this works properly), eventually this should replace the clipping
219       of ice velocities in seaice_dynsolver to +/-40cm/s.
220    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
221      include it only where its needed
222    o move balancing of fluxes before the call of external_forcing_surf
223    o seaice:
224      - correct units of turning angles (now they are really in degrees)
225      - move computation of GWATX/Y out of main routine into dynsolver
226      - initialize GWATX/Y in seaice_init
227    o Apply mask on Fresh-Water flux (needed for SSH forcing).
228      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
229    o seaice: add runtime flags for turning angles (default to zero)
230    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
231      and trend from exf forcing and ctrl control adjustments
232    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
233      (since checkpoint57x_post)
234    o change the default rotation period to 86164.s = the Earth rotation
235    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
236      and based on a reference stratification. Tested within hs94.cs-32x32x5.
237    o seaice advection: add code for choosing between the default (2nd order
238      central differences) and multiDim advection schemes provided by
239      pkg/generic_advdiff
240    o seaice:
241      - removed all references to SEAICE_GRID.h fields from
242        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
243        (cubed-sphere configuration will change a little)
244      - grid computations in seaice_init are obsolete now.
245      - cleaned up code a little so that is easier to read (hopefully).
246      - added new (better?) discretizations of default advection and diffusion
247        (turn on with SEAICEuseFluxForm)
248      - replace 1 in 3d global fields by kSurface in growth.F
249      
250    checkpoint58a_post
251    o seaice:
252      - bug fix in advect.F
253    o shelfice:
254      - separate shelfice load anomaly from pload (breaks with time
255        dependent forcing), => introduce constant field shelficeLoadAnomaly.
256        Its default is 0., but it may be computed more cleverly from (unknown)
257        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
258        done offline. A good approximation of the pressure load anomaly is
259        necessary to avoid large initial adjustment processes underneath
260        deep-reaching shelfice.
261      - small fix in ISOMIP shelfice_thermodynamics
262      - add more sophisticated thermodynamics of Hellmer (1989), this is
263        now the default
264      - give a few constants more intuitive names
265    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
266      if bulk formulae are used in long integration (especially EmPmR). Turn
267      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
268      if balancePrintMean, the imbalance that is substracted is printed to
269      STDOUT.
270    o fix bug (typo) in obcs_apply_eta.F
271    o add a new package shelfice which enables us to model the circulation
272      underneath shelf-ice with draughts of hundreds of meters.
273     - works
274     - to do: + include improved thermodynamics
275              + check whether kSurfC (from model/inc/SURFACE.h) can be used
276                instead of new field kTopC
277              + can we use topoFile, Ro_surf and existing code in ini_depth.F
278                instead of new field R_shelfIce and new code in ini_depth.F
279                and ini_mask_etc.F?
280              + adjust vertical mixing schemes?
281    o seaice pkg:
282     - add a cpp-flag to include a simple formula for a salinity dependent
283       freezing point of sea water at the surface
284     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
285       meridional stresses are now different (and hopefully correct)
286    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
287       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
288       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
289    o pkg/diagnostics: add options and parameters for regional-statistics
290       diagnostics ; define regions by reading a region-mask from a file
291       (might add other options later)
292    o pkg/bulk_force:
293     - add option and parameters to use AIM surface-flux formulae.
294     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
295       others forcing fields (defined in PARM05, parameter file "data") are loaded
296       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
297     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
298     - use the right EXCH call for uwind,vwind (to work on CS-grid).
299     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
300       and parameters (note: calcWindStress replaces .NOT.readwindstress).
301     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
302    
303    checkpoint58
304    o add "--embed-source" option to genmake2 which, when the supporting
305      tools can be compiled (as determined by genmake2) will turn on the
306      embed_files package which then embeds the entire MITgcm source code
307      (*.[fFhc] + Makefile) used for the build within the executable
308      - requested by CNH but off by default
309      - adds a paltry <9MB to the mitgcmuv executable in most cases
310      - only writes the output when useEMBEDSRC in eedata is true
311    o clean up 3-dim. relaxation codes:
312      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
313      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
314      * Thanks to Tom Haine for testing!
315    
316    checkpoint57z_post
317    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
318      affects output (@ truncation level) of exp. plume_on_slope ; updated.
319    o fix the pickup behavior for obcs in combination with ptracers
320    o fix a bug in ptracers_external_fields_load
321    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
322      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
323    o transfered surface NH pressure to eta field (if exactConserv).
324    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
325         and update lab_sea output.txt file.
326    o completing 3-dim. relaxation code: additional term
327         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
328      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
329      * At compile time, in "EXF_OPTIONS.h" set
330          #define  ALLOW_CLIMTEMP_RELAXATION
331          #define  ALLOW_CLIMSALT_RELAXATION
332      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
333          tauThetaClimRelax3Dim = 15552000.0,
334          tauSaltClimRelax3Dim  = 15552000.0,
335      * 3 cases:
336          1) Use a constant-in-time 3-dim. field
337          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
338          3) Real-time relax. to time-evolving prescribed field
339    o Adding Laplacian-type smoothness constraint on
340      initial and boundary (forcing) controls (ic, bc)
341      * enable at compile-time via
342        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
343      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
344      * Absolute scale somewhat unclear so far
345      * no area weighting was included since no other cost term does so far
346    
347    checkpoint57y_post
348    First step for a NLFS adjoint
349    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
350    o new init. routines for calc_r_star, calc_surf_dr
351    o still need to deal with ini_masks_etc
352    o testreport seemed happy
353    checkpoint57y_pre
354    
355    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
356    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
357    o add new offset feature to offline pkg (plus minor cleanup)
358    o cfc fixes for final year of integration
359    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
360      be in GCHEM_OPTIONS).
361    
362    checkpoint57x_post
363    o fix testreport Pb in multiple test experiment.
364    o cleanup our namelist syntax in verification:
365      - make it more F95 standards compliant (some work still needed)
366      - allows the vast majority of our tests to work with gfortran
367    o Non-Hydrostatic:
368     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
369     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
370    o Allow to apply AB on T,S rather than on AB(gT,gS):
371     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
372     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
373       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
374     - need a "clever" read_pickup to restart from the other AB formulation
375    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
376    o remove some unused variables (reduces number of compiler warnings)
377    o adjoint
378      * Disable useVariableViscosity for adjoint for time being
379        (there are a number of extensive recomputations)
380      * Initialize certain variables needed for adjoint
381    
382    checkpoint57w_post
383    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
384                 fix the singleCpuIO RS version of MDSWRITEFIELD
385       and add a WARNING if using globalFiles=T with multi-processors.
386    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
387      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
388    o tracer advection scheme:
389      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
390       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
391       was not very convenient).
392      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
393       (further tests needed for the implicit DST & Flux-Limiter schemes).
394    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
395      and sRef for convenience, handy, when you want to initialize
396      ptracers in a large domain with a constant non-zero value. Also,
397      untangle ptracers_init.F a little.
398    
399    checkpoint57v_post
400    o change dome exp. to use variable viscosity in side-drag terms.
401    o remove all the files from the cfc_offline test since they are now
402      incorporated into tutorial_cfc_offline which has been producing
403      identical results for a few days of testing
404    o add new parameter: sideDragFactor to enable half-slip-side BC
405      and change side-drag S/R to use viscosity from mom_calc_visc
406      (can switch back by setting sideDragFactor=0.); affects results at
407      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
408       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
409    o vorticity & strain are now computed without masking, to account for
410      no-slip-side BC in variable viscosity calculation ; mask is applied
411      anyway later on, before computing advection/coriolis terms.
412    o modify exp4 to test new obcs support for reading from external files
413      and for passive tracers
414    o fix behavior of ptracers_monitor when monitor output is written to a
415      netcdf-file; still not independent of monitor.F (writes in the same
416      file).
417    o change default value of tRef (put a uniform, meaningful value for ocean
418      & atmos) and initialize sRef (was missing, as Martin mentioned).
419    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
420      to be proportional to enstrophy dissipation length.  Thus,
421       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
422      This is now consistent with Smagorinsky and with the manual.
423    
424    checkpoint57u_post
425    o OBCS and PTRACERS: add open boundary support for passive tracers
426      - either use homogenous (pseudo) v.Neumann conditions or prescribe
427        OB-values from file; this is not different from the way theta and salinity
428        are treated
429      - however, Orlanski-radiation conditions are not supported, and the model
430        will stop if you use pTracers and Orlanski at the same time.
431      - beefed up the rountine obcs_external_fields_load: now only those open
432        boundary values are overwritten with values from files for which there
433        are really files, otherwise the OB-fields remain untouched. This makes
434        it possible to use different OBs at different ends of the domain (as
435        with EXF)
436    o reduce number of exch calls in shap_filt (s2).
437    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
438      truncation level) 4/5 MLAdjust test results (11&12 digits match).
439    
440    checkpoint57t_post
441    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
442    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
443      same truncation, independent of the face number: affects affects several
444      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
445    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
446      note that biharmonic viscosity + no-slip was not tested in any experiment.
447    o fix bug in non-linear free-surf side-drag ; generate new output for
448      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
449    o make mnc honor the writeBinaryPrec flag for most kinds of output
450    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
451    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
452      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
453    o add brackets in multi-terms sum to get same truncation, independent of
454      the face number (manage to get exactly same value of gU,gV at the cs-edge)
455      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
456    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
457      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
458      a maximum grid-scale Reynolds number.  Also, changes all length calculations
459      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
460      Suggested values of viscosity parameters found in mom_calc_visc.
461      Many new viscosity diagnostics available.
462    
463    checkpoint57s_post
464    o Add clearing-house for viscosity calculations, mom_calc_visc and
465      correct numerous bugs in LeithD and Smagorinsky discretizations.  
466      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
467      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
468      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
469      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
470      The Strain-Tension form is now called with useStrainTensonVisc=.true.
471      ViscAhStrain and viscAhTension are now retired.
472    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
473    o In response to JMC's bug report, genmake2 now ignores any soft-links
474      that it finds in the *current* directory when searching for files.
475      Soft-links found in any other source directories will still work as
476      they did before.
477    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
478      a C routine to unlimit the stack size
479    o mnc-ify pkg/aim snapshot vars
480    o mnc-ify pkg/land as requested by Daniel
481    o various changes to mnc including:
482      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
483      - output can now be grouped so that all files within a group
484          change the ITER portion of their names in lock-step together
485      - can now read ("global") PER-FACE (in addition to PER-TILE) files
486          and works with both EXCH1 and EXCH2 (but needs more testing)
487      - writing works for all verification test cases w/ g77 on Linux
488    
489    checkpoint57r_post
490    o make MNC variable initialization happen earlier
491    o add diagnostics for (almost) each term of the momentum Eq.
492    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
493    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
494    o remove MINIMAL_TAVE_OUTPUT option ;
495      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
496    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
497      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
498    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
499    o add time-dependent SST, SSS control
500    o cost terms in ecco/ modularized (new cost_generic.F)
501    o cost_averages routines are modularized (new cost_averagesgeneric.F)
502    o new infrastructure for seaice model vs. obs misfits in seaice/
503      * driver from the_main_loop.F is seaice_cost_driver.F
504      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
505      * gradient check in Exp. 6a of natl_box_adjoint/
506    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
507      (see README file)
508    
509    checkpoint57q_post
510    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
511    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
512      - bug was reported by Jean-Michel and Ian Fenty
513    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
514      update exp. cpl_aim+ocn output.
515    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
516      Needed for high-res. runs with large global files
517      to be able to limit tapelev size
518    o Changed some tests for adjoint:
519      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
520      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
521      * global_ocean.90x40x15/ back to default 3-level checkpointing
522    o Modifications to enable scripted COMMON to MODULE conversion
523      * verification/OpenAD/code/ has necessary scripts and description;
524      * converts, compiles and runs successfully;
525    
526    checkpoint57p_post
527    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
528    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
529      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
530    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
531    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
532      (was already the case for dissipation with mom_vecinv,
533       and also the case for grad.PhiHyd when staggered-timeStep)
534      This will allow to put dissipation out-off the AB time-stepping.
535     Unfortunately, affects truncation error. Update output of exp. that "fails"
536      (cg2d matching number) and leave the others for later: front_relax(10),
537      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
538      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
539    
540    checkpoint57o_post
541    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
542      (2) its ready to be documented during the 20050801 DocFest
543    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
544      for ideal_2D_oce and lab_sea on linux_ia32_g77
545    o set to #undef CTRL_SET_OLD_MAXCVARS_30
546      in global1x1_tot/code_seaice_adj to access indices 32, 33
547      (worth another tag)
548    
549    checkpoint57n_post
550    o adding precip control xx_precip 32
551    o adding swflux control xx_swflux 33
552    o Replacing 10 forcing penalty cost routines by 1 generic.
553    o Implementing partitioning in time-mean and variable adjustment
554      for atmos. state.
555    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
556    o in natl_box_adjoint:
557      * updated exp 1 to 10
558        (but does not have time-mean vs. variable split results yet)
559    o updated global1x1/*_seaice_adj/
560      to incorporate latest changes
561    o enable useSingleCpuIO for mdsio vector routines
562      (applies in particular to tapelev I/O)
563    o removed inefficient K-loop in all active_file*control*.F
564    
565    checkpoint57m_post
566    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
567      and advect_cs (use EXCH-2 and standard cs-32 grid files).
568    o pkg/exch2: filling of face-corner halo regions is optional
569      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
570    
571    checkpoint57l_post
572     tag before updating tutorials (pre-release-2)
573    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
574       for output and interpolation of input fields onto model grid)
575    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
576       Affects results of exp. rotating_tank ; update output.txt.
577    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
578          and taking the square quantity and/or using a fraction-weight field.
579    o fix aim_diagnostics_init.F mate numbers.
580    o add mnc output capability to diagnostics/diagstat and update
581      our cvsignore files for the ACSII output generated
582    
583    checkpoint57k_post
584    o lab_sea now uses diagnostics package and provides a suite of
585      new EXF diagnostics output.
586    
587    checkpoint57j_post
588    o exf
589      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
590        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
591        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
592      * extended diagnostics output
593        - now includes all EXF variables
594        - hs, hl moved to common block
595        - separate S/R for diagnostics, called after ctrl vector is added
596        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
597        - EXFqnet contains true Qnet (i.e. includes qsw)
598      * updated verif. lab_sea, global_with_exf
599      * Rearranging hflux (exf_mapfields -> exf_getforcing)
600        to ensure that diagnostics sees a true EXFqnet
601    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
602    o diagnostics pkg: change pointers so that 1 diagnostic can be used
603      several times with different frequencies.
604    o mnc-ify the thsice package as requested by Daniel Enderton
605      - the monitor--MNC output needs work
606      - many attributes need to be added (most are currently blank)
607    o mnc-ify theaim_v23 package as requested by Daniel Enderton
608      - many attributes need to be added (most are currently blank)
609    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
610    o add Sadourny like discretization to the 4th.O vorticity advection scheme
611    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
612      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
613         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
614    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
615     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
616    
617    checkpoint57i_post
618    o Diagnostics package was changed: diagnostic allocation is now deactivated
619      by setting an empty file name in the namelist (used to be by setting 0 frequency)
620    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
621      add 1rst Order upwind vertical Shear.
622    o add a quick fix for A/B checkpointing in OFFLINE mode
623    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
624      end-run around the C/Fortran linking horror in eesup/src/timers.F
625    o added pkg/runclock: allows user to terminate run based on wall clock
626    o added non-hydrostatic scaling parameter: nh_am2
627    o pkg/my82: futile attempt to make results compiler-independent by adding
628      some "_d 0", etc. no effect.
629    o for mnc output, fill the 'T' coordinate var with myTime and create a
630      separate 'iter' variable for iteration count
631    o pkg/diagnostics:
632      add new capability: output of Global/Regional & per-level statistics ;
633      tested against monitor output (including land & thSIce) on various exp.
634    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
635    
636    checkpoint57h_done
637      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
638      data.diagnostics, data.gchem, data.ptracers) is done.
639    
640    o pkg/diagnostics: prepare for Global/Regional statistics.
641      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
642    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
643      and rename it: DIFFERENT_MULTIPLE
644    
645    checkpoint57h_post
646    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
647    o pkg/diagnostics: change output frequency, now in seconds (instead
648      of Nb of iterations). This requires to change data.diagnostics.
649    checkpoint57h_pre
650    
651    o in mnc, let the user create the output dir if both mnc_outdir_date
652      and mnc_outdir_num are false
653    o add fflags() to pkg/diagnostics which allows one to specify, on a
654      per-file basis, the file precision [default behavior is unchanged]
655    o added diagnostics to pkg/kpp, including computation of mixed layer
656      depth based on a temperature/density criterion
657    o updated verification/natl_box to test the new pkg/kpp diagnostics
658    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
659    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
660    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
661      not mnc -- this mistake was found by JMC and is now corrected
662    
663    checkpoint57g_post
664    o add Adams-Bashforth 3rd Order time stepping:
665      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
666      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
667    checkpoint57g_pre
668    
669    o make lambda[Theta,Salt]ClimRelax spatially varying
670      (default remains spatially uniform constant based on tau)
671    o added new control variables
672      * init. uVel, vVel, etanN
673      * lambda[Theta,Salt]ClimRelax
674    o separate masks used for ctrl_pack/unpack 'from write_grid' output
675      (suggested by G. Forget)
676    
677    checkpoint57f_post
678    o add parameter "baseTime" = model base time = time at iteration zero
679      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
680      account for baseTime shift
681    o move Coriolis arrays from PARAMS.h to GRID.h
682    checkpoint57f_pre
683    
684    o mnc-ifying the seaice package
685    o introduced an alternative length scale calculation for use in the limiting
686      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
687    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
688    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
689      as well as grad(vort3).  Made it compatible with both approximate form
690      for the cubed sphere and full form of these gradients.  Added flag
691      useFullLeith to select between approximate and full form.  
692    o add "d0" in getcon.F to reduce differences between compilers/platforms
693      update output.txt of exp. fizhi-gridalt-hs
694    o change port_rand funtion to allow to set the seed.
695    o fix obscure MNC bug involving conversion between reals and integers
696      - it caused no problems with certain (eg. gcc, ifc) compilers but the
697        new version is now more standards-compliant
698    o adjoint-related modifications
699      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
700      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
701      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
702    
703    checkpoint57e_post
704    o Adding eddy stress controls a la Ferreira et al.
705    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
706    
707    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
708      update output.txt of exp. fizhi-gridalt-hs
709    o add more "Z" dimensions and associated coordinate vars to MNC
710    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
711    o parameter calendarDumps: when set, approximate months (30-31 days) and years
712      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
713      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
714      months and years.  Requires pkg/cal.
715    o diagnostics: add pickup functionality
716      - off by default for backwards compatibility
717      - current version only uses MDSIO -- MNC will be added
718    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
719    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
720    
721    checkpoint57d_post
722    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
723    o modify verification/ideal_2D_oce so that it tests the creation of mnc
724      output from the diagnostics package
725    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
726    o make genmake2 more portable by using ".$FS" instead of ".f" for more
727      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
728    o add coordinate variables to the MNC output from the diagnostics package
729    o change MNC-flags default value: true when useMNC=TRUE
730    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
731      the ability (off by default) to read the grid information using MNC
732    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
733    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
734    o do snap-shot diagnostics at the middle of the time-interval (instead of
735      at the end).
736    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
737      new test for AIM with thSIce + slab-ocean
738    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
739    o move state variable diagnostics to the beginning of the time step ;
740      (note: still needs some work specially for snap-shot diagnostics)
741      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
742    
743    checkpoint57c_post
744    o Change testing option (-ieee) to get closer agreement between g77 & ifort
745    o generate new output.txt files on faulks with g77 & the new -ieee option
746    checkpoint57c_pre
747    
748    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
749      update output.txt of exp. global_ocean.90x40x15
750    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
751      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
752    o add saltFlux(+File) forcing capability with periodicExternalForcing
753    o allow to use pkg diagnostics for GM-Redi & ThSIce output
754    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
755    o improvements for the MNC output from DIAGNOSTICS:
756      - correct handling of the unlimitied dimension
757      - all dims now have associated coordinate variables
758      - variables located at U, V, and Corner ("Z") points are now written
759        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
760        *all* data points are output
761    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
762    o added pkg/seaice/seaice_monitor.F
763    o mdsio_readfield.F can now read files visible only to master MPI process.
764    o pkg/seaice: some test code for ice-modified ocean stress
765    o exf_getffields interpolation defaults to bilinear for all scalar forcing
766      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
767      spurious negative numbers for precipitation and humidity.  Will cause
768      some small numerical differences for integrations using pkg/exf/exf_interp.F.
769    o pkg/ctrl/
770      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
771        May be enabled via doPackDiag
772      *  introduce z-scaling of
773         + gradient (doZscalePack) and
774         + control (doZscaleUnpack)
775    o pkg/mdsio/
776      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
777      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
778    
779    checkpoint57b_post
780    o simplify options in diagnostics_fill arguments (remove weird combinations)
781    o fix MNC coordinate variables so that they now contain per-face index
782      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
783      general, EXCH2 grids are only aligned to a "local" coordinate system
784    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
785    o Implement instantaneous output within pkg diagnostics:
786      setting a negative frequency in data.diagnostics produces
787     "snap-shot" output (as opposed to time-average if freq > 0)
788    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
789      NOTE: change ptracer diagnostics name: use 2 characters to work with
790            more than 9 tracers. Add also diagnostics of advect & diffus flux.
791    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
792      becomes the coordinate variable for the 'T' dimension
793    o add CF-style coordinate variables to MNC
794      - just a first cut:  numbers are meaningless on the cubesphere and
795        missing along the T axis but otherwise it works!
796    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
797    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
798    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
799      this is based directly on what the model compute, so that the content of
800      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
801    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
802    o clean up build options files for SunOS, in particular
803      - remove -traditional from xmakedepend
804      - change -xarch=v9 to -xarch=native for f77
805      - restore use of make (not gmake)
806      - add CC=gcc if using g77
807    o changes per discussion of AM, JMC, & EH3 today:
808      - move redundant "grid" variables out of "state" -- in preparation of
809        creating proper CF-style coordinate variables and in recognition
810        that any/all grid variables can be easily copied (eg. w/NCO) from
811        the grid files into any of the other NetCDF files
812      - *always* output grid variables with MDSIO (this will eventually be
813        changed)
814      - output MNC grid file if useMNC is true
815    o every instance of _END_MASTER() has been found and replaced with
816      _END_MASTER( myThid ) in order to satisfy certain picky Sun
817      preprocessors
818    o re-arrange diagnostics pkg initialisation:
819     - allow each package to extend the available diagnostics list
820     - add some checking and fix small problems (multi-threaded, ...)
821     - new S/R diagnostics_fill (replace fill_diagnostics):
822       look through the short list of active diag. (instead of the long list)
823       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
824    
825    checkpoint57a_post
826    o this set of changes restores TAMC compatibility
827      tested for global_ocean.90x40x15 adjoint on trough
828      (what a pain)
829    
830    checkpoint57a_pre
831    o some modifs in tools/build_options for sunos
832    o call ctrl_pack for ctrl at end for optimcycle=0
833    
834    checkpoint57
835    o add horizontal bi-harmonic viscosity for vertical velocity
836      - new parameter viscA4W (defaults to viscA4)
837      - affects only non-hydrostatic code
838      - to be done: no-slip lateral boundary conditions
839    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
840    o implement Implicit Vertical advection for pTracers
841    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
842      (implemented also for implicit vertical diffusion & advection)
843    o OBCS: extend application of tracer open boundary conditions
844      to a strip beyond the boundary of width Olx/Oly
845    o add call monitor to TAF set of required calls (flow directives)
846      and include in natl_box_adjoint
847    o untangle a few ifdefs related to cost, ctrl, autodiff
848      untangel a few ALLOW_ECCO_OPTIMIZATION
849    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
850      (theta2, salt2 in ecco_cost_weights)
851    
852    checkpoint56c_post
853    o OBCS as control variables
854      - update ctrl_ad_diff.list, obcs_ad_diff.list
855      - remove balance of obcs controls from default
856      - fix index bug nobcs in ctrl_init
857      - fix dummy fields filen in ctrl_pack
858      - add dummy weights for obcs
859    o lsopt: comment out fort.94 output
860    o optim:
861      - remove unnecessary header files
862      - adjusted namelists
863      - add xerbla.F to Makefile
864    o exf:
865      - multiple modifications of exf_check_range
866      - unit change in exf_init_runoff from [m/year] to [m/s]
867    o mdsio:
868      - i/o-vector change debugLevel from debLevA to debLevB
869    
870    checkpoint56b_post
871    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
872      is called from DO_THE_MODEL_IO
873      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
874      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
875      - clean up PTRACERS_WRITE_TIMEAVE a little
876    o add another verification experiment that tests both the cfc-pkg and
877      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
878      reactive tendencies treated inline with regular timestepping
879    o testreport previously did a lousy job of comparing small numbers, so
880      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
881      implemented in the little c-progam tmp_cmpnum.c which is embedded in
882      testreport.
883    o ptracers_monitor: bug fix for MPI
884    
885    checkpoint56a_post
886    o GCHEM: finish reorganizating the package
887      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
888        (introduces another 3D-array for each passive tracer, but only if
889        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
890        gchemTendency is not needed because the timestep is done separately)
891      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
892      - GCHEM is now---more or less cleanly---separate from PTRACERS
893      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
894        so clear to me how that should be done in a general way.
895    o CFC: improve formatting of output in CFC_ATMOS
896    o PTRACERS:
897      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
898        that ALL experiments with ptracers enable can be checked. This makes
899        GCHEM_MONITOR obsolete.
900      - include a runtime parameter PTRACERS_monitorFreq that defaults to
901        monitorFreq
902      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
903    o add PTRACERS (PTR0[1-5]) to testreport output
904    o exf_check_range:
905      * default changed to .TRUE.
906      * will check values for niter0 if debLevA, every timestep if debLevB
907      * STOP in exf_check_range if 'out of range'
908      * range chosen generous to allow for potential extema
909      TBD: a version with stricter range
910           permitted range would be runtime parameters
911    o GMredi:
912      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
913      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
914      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
915    o GCHEM:
916      - move call to GCHEM_FORCING_SEP, so that it is now called before
917        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
918      - introduced a useGCHEM runtime flag and applied it everywhere.
919      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
920        this flag is now only visible within GCHEM-pkg routines.
921      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
922        be replaced by a 3D array that is computed before thermodynamics; for
923        this, the tracer ID iTracer had to be included into the parameter list
924        of ptracers_forcing
925      - set up forward_step to call gchem_forcing, that will replace
926        gchem_forcing_int in ptracers_forcing
927      - cleaning up
928    o small cleaning of exch2: remove files that are also in eesupp/src
929    
930    checkpoint56
931    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
932    o mnc: cleanup "full" files--fixes out-of-memory problem
933    o ECCO-GODAE
934      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
935      * fully merged and updated from SIO code
936        windstress sign change affects
937        - exf_inscal_[u/v]stress
938        - sign of xx_tau[u/v] adjustments
939        - signs in cost_scat
940      * ctrl_get_gen: avoid update of tau[u/v] for first few days
941      * natl_box_adjoint updated and compressed
942      * 2-level checkpoint switch added
943        (tested in EXP. 1 of natl_box_adjoint)
944      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
945    o SVD
946      * first complete, non-hacked version for SVD calculations
947      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
948        performed via direct access files admtlm_vector.it????
949        (via ctrl_[un]pack)
950      * optimcycle is used for ARPACK iteration counter
951        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
952      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
953        and add linear transforms where necessary
954      * controls are initial/final SST, SSS (can be extended; need to check
955        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
956    o mdsio: filename info to both stderr, stdout
957    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
958      from sign change
959    
960    checkpoint55j_post
961    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
962      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
963    o add consistent build directories and .cvsignore files to verification
964    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
965    o make all subroutines 30 or less characters in length for certain older
966      compilers to work (a thorough search only turns up two routines in
967      pkg/ptracers)
968    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
969      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
970    
971    checkpoint55i_post
972    o change arrays for total vertical diffusivity (2.D if explicit,
973      3.D if implicit) ; each ptracer uses its own background value.
974    o added mnc/NetCDF output capability to ocn_compon_interf
975      - added bits to verification/cpl_aim+ocn so that it can run on
976        ITRDA and other clusters without the mpirun "-wd" option
977    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
978      configuration
979    o give MNC the ability to create additional files rather than
980      exceeding a specified file size limit "MNC_MAX_FILESIZE"
981      - the default is just less than 2GB which is a practical limit
982        on many systems
983    o Compute the non-local term using either KPP vertical diffusivity (=default)
984       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
985    
986    checkpoint55h_post
987    o add verification test "vermix"
988    o remove all the *_ioinc flags and replace with the single global
989      outputTypesInclusive flag
990    o allow to set a vertical profile of vertical diffusivity for T & S
991    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
992    o useMNC moved from data.mnc to data.pkg
993    
994    checkpoint55g_post
995    o Renaming carbon AD experiments to comply with testreport conventions
996    o Updating adjoint of Held-Suarez hs94.1x64x5
997    o Fixing directives for non-ECCO forward_step, after ECCO directives
998      have been fixed to avoid recomp. of do_oceanic_phys
999      Works well for global_ocean.90x40x15,
1000      but recomp. issue remains for carbon
1001    o Updating adjoint output for natl_box_adjoint after
1002      pkg/ecco has been modified (see taga c55d_post)
1003    
1004    checkpoint55f_post
1005    o rename to timeave_init_fixed
1006    
1007    checkpoint55e_post
1008    o some delicate re-shuffle of store directives to avoid one
1009      extra call of do_oceanic_physics
1010      affects ecco_the_main_loop.F, do_oceanic_physics.F
1011      checkpoint_lev1_directives.h
1012    o NB: this may break global_ocean adjoint temporarily,
1013      but it is clear how to fix it. Will do later, need this now.
1014    
1015    checkpoint55d_post
1016    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1017    o ecco_cost_weights is modified to 1x1 runs
1018    o modifs to allow observations to be read in as
1019      single file or yearly files
1020    o enable to read exf forcing fields as either
1021      single file or yearly files (flag useExfYearlyFields)
1022    checkpoint55d_pre
1023    
1024    o switch between 2-level and 3-level checkpointing
1025    o add ability of MNC to write local and "partial" (eg. 2D slices where
1026      the full 3D field is never actually stored) arrays to NetCDF files
1027      with the correct (that is, the complete multi-dimensional) set of
1028      array indicies
1029      - used in mom_vecinv() to write the diagFreq output
1030      - tested (demonstrated) in verification/aim.5l_cs
1031    o further mnc-ification
1032      - add verification/lab_sea to the list with mnc setups
1033      - fix undefined mnc v-names in cd_code
1034      - add kpp to mnc output (both snapshot and timeave)
1035    o non-hydrostatic code
1036      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1037        in calc_gw.F
1038      - defaults to viscAh
1039      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1040        friction or Leith) in non-hydrostatic mode, as long as there is
1041        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1042    o pkg/cost
1043      extend simple cost functions to treat time mean quantities
1044      (T,U,V) via cost_accumulate_state from cost_tile
1045    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1046        be 2 times larger than the minimum size the advection scheme requires.
1047        now get a perfect conservation of salt in advect_cs test-exp (updated)
1048    o GGL90 (Gaspar's TKE mixed layer)
1049      - add horizontal diffusion of TKE, requires exchanges in
1050        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1051        default. In OPA there is no horizontal diffusion of TKE but the
1052        mixing coefficients are computed from a horizontal average of TKE of
1053        6 points or so. I think that diffusion has a little more physical
1054        justification.
1055      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1056        was in vain)
1057      - mask tke-variable in ggl90_init
1058    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1059    o fix biharmonic diffusion on CS-grid.
1060    o more obcs stuff
1061      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1062        for reading boundary values. This routine is called from
1063        obcs_prescribe_read
1064      - updated obcs_check
1065      - changed sponge layer relaxation parameter units for days to seconds
1066      - turned off sponge layer by default
1067      - changed argument list of OBCS_CALC to myTime+deltaTclock
1068      - fixed about 35 bugs in obcs_external_fields_load
1069    
1070    checkpoint55c_post
1071    o obcs stuff
1072      - new runtime flags useOBCSprescribe, useOBCSbalance
1073      - re-arranged obcs_calc
1074      - moved exf_getobcs to obcs_prescibe_read
1075        obcs_prescibe_read is called after ORLANSKI stuff
1076        and independent of it (executable can contain all).
1077      - updated obcs_check
1078      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1079        These may be necessary only if tangential velocities are
1080        prescribed at OB, not sure, needs testing.
1081    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1082      which simplifies the calls and passes the ifc check-bounds test
1083    
1084    checkpoint55b_post
1085    o add a 2D scalar, Z location, exchange_2 routine.
1086    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1087      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1088      affects advect_cs results (for the wrong reason): update output.txt
1089    o use a more standard discretization for biharmonic viscosity ;
1090     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1091      affects results of dome set-up: update output.txt
1092    o fix gad_advection.F (CubedSphere part), back to version 1.23
1093    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1094    
1095    checkpoint55a_post
1096    o merged code to
1097      * prescribe/read time-dependent open boundaries
1098        (works in conjunction with exf, cal)
1099      * sponge layer code for open boundaries
1100      * each boundary N/S/E/W now has its own CPP option
1101        (healthy for the adjoint)
1102    
1103    checkpoint55
1104    o up-to-date adjoint of previous breaks
1105      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1106      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1107      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1108      - carbon: * remove tr1-related adjoint verification
1109                * add ptracer as control variable
1110    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1111      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1112    
1113    checkpoint54f_post
1114    o in verification/carbin/ remove experiment related to
1115      ALLOW_PASSIVE_TRACER (array tr1 etc)
1116      code_ad/ input_ad/ results_ad
1117    
1118    o add two new packages
1119      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1120        + subject to optimization (memory)
1121      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1122        + subject to reordering (many GOTOs in the original code)
1123        + so far opps is called for every (i,j) point, and then operates in
1124          the vertical; one may want to reorder the scheme in order operate in
1125          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1126          fields)
1127    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1128      - all verification tests compile and run with linux_ia32_g77
1129      - defaults are compatible with current input files--nothing
1130        should change if you were not previously using MNC
1131      - MNC output has been added in numerous places (eg. timeave)
1132        but there are still a few writes not yet do-able with MNC
1133        (this is in progress)
1134      - flags now allow for either/or/both use of MDSIO and MNC and
1135        documentation will soon follow
1136      - numerous small formatting cleanups for ProTeX
1137    o add version info (via BUILD_INFO.h) to MNC and stdout
1138    
1139    checkpoint54e_post
1140    o add two new packages
1141      - pp81 (Packanowski and Philander, 1981), Richardson number and
1142        stratification dependent mixing
1143      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1144      - these scheme operate in a similar manner as KPP (without ghat, of
1145        course), however there is only one diffusivity that is used for both
1146        temperature and salinity (and passive tracers)ç
1147    o add offline package
1148    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1149      provided by Stephanie Dutkiewicz
1150    o genmake2: add ability to search for C compilers and cleanup test output
1151      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1152    
1153    checkpoint54d_post
1154    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1155    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1156      leading to additional shift by 5 days each year of integration
1157       (i.e. leading to considerable offset over the years)
1158    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1159    o start with no AB and no initial filtering (staggerTimeStep):
1160      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1161    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1162      (external loading & cpl import/export stay in forward_step.F)
1163    o update coupling interface to work with new staggerTimeStep
1164    o change MDSIO ptracers_pickup.
1165    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1166    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1167    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1168    
1169    checkpoint54c_post
1170    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1171      this affects (truncation error) output.txt of test-exp:
1172       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1173    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1174    o change Qnet to always be the net heat flux, (+upward).
1175      affects (truncation error) output of natl_box exp.: updated
1176    o define the max number of passive tracers in PTRACERS_SIZE.h
1177    o start to test mnc routinely in exp0
1178    o add sea-ice loading (sIceLoad) as a new forcing field.
1179    
1180    checkpoint54b_post
1181    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1182       impressive on Altix and Opteron systems)
1183    o diagnostics can now write NetCDF files through the mnc package
1184    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1185    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1186    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1187      affects (truncation error) output of lab_sea & natl_box exp.: updated
1188    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1189    
1190    checkpoint54a_post
1191    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1192    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1193    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1194    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1195      + internal_wave (shift in writing cg2d_ini_res)
1196    checkpoint54a_pre
1197    
1198    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1199      - modified verification/lab_sea and natl_box_adjoint accordingly
1200    
1201    checkpoint54
1202    checkpoint53g_post
1203    o prepare splitting of thermodynamics: store convect.counter in common block
1204    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1205      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1206    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1207    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1208    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1209    o restore adjointability
1210    
1211    checkpoint53f_post
1212    o modifications that affect AIM experiment results (update output.txt):
1213      - no advection of S at top interface Nr (pkg/generic_advdiff)
1214      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1215    o AIM pkg:
1216      - include stability function into surf.Flux derivative relative to Tsurf
1217      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1218    
1219    checkpoint53e_post
1220    o merged cylindrical coord configuration
1221    o added rotating_tank experiment
1222    checkpoint53e_pre
1223    
1224    checkpoint53d_post
1225    o faulks upgraded: re-generate output.txt that have changed:
1226       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1227    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1228    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1229    o added Sadourny discretization of Coriolis
1230      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1231      - re-enabled use of omega3 (useAbsVorticity)
1232    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1233      vector-invariant equations
1234      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1235    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1236      hopefully without new bugs
1237      - still to do: biharmonic friction for non-hydrostatic w
1238    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1239    o regenerated output for global_ocean_ebm (using -ieee)
1240    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1241      of mom_common/
1242      - simple re-arrangement of instructions within computing loop
1243    checkpoint53d_pre
1244    
1245    checkpoint53c_post
1246    o new version of coupler for AIM+thSIce and Ocean models
1247     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1248     - land: change Evaporation of snow
1249     - aim with thSIce: fix bug in snow-precip.
1250    o changes to calc_gw.F
1251     - bug fix for w^2 term near the bottom boundary
1252     - (hopefully) improve the lateral slip boundary condtions for use with
1253        partial/looped cells
1254      - because the bug fix changes two verification experiments anyway (exp5
1255        and plume on slope), change the lateral boundary condition from half slip
1256        to the value of no_slip_sides
1257    o ebm package wasnt quite up to the parallel task. Fixed that.
1258    o Adjoint of EBM package + verification
1259      * TLM OK
1260      * ADM not sufficient accuracy yet (needs further testing)
1261    
1262    checkpoint53b_post
1263    o Commiting new energy balance model to repository
1264      * package is pkg/ebm
1265      * verif. is verification/global_ocean_ebm
1266      * references are in ebm_driver.F
1267    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1268    C        Global thermohaline circulation. Part I:
1269    C        Sensitivity to atmospheric moisture transport.
1270    C        J. Climate 12(1), 71-82
1271    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1272    C        Global thermohaline circulation. Part II:
1273    C        Sensitivity with interactive transport.
1274    C        J. Climate 12(1), 83-91
1275    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1276    C        Destabilization of the thermohaline circulation
1277    C        by atmospheric eddy transports.
1278    C        J. Climate 7(12), 1870-1882
1279    o Will need long integration testing.
1280    checkpoint53b_pre
1281    
1282    o created pkg/mom_common in preparation for variable viscosity code
1283    o renamed and split ini_mnc_io
1284    o pkg/land: only liquid water can diffuse or run-off
1285    o AIM using land: soil wetness availability account for snow
1286    o added printMapIncludesZeros to EEPARMS namelist
1287    
1288    checkpoint53a_post
1289    o restore TAMC compatiility for exf_constants.h
1290      (no usage of _d in .h)
1291    o Additional storing in KPP in an attempt to fix
1292      TAMC problem with adjoint of KPP code.
1293      (no success...)
1294      Identical code works fine with TAF.
1295    o Fixed verification/natl_box_adjoint experiments.
1296      Initial conditions for Experiments 4 and 5 are now
1297      set to "SEAICE_initialHEFF=0", which is more reasonable,
1298      and hence gives results closer to that of Experiment 2.
1299      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1300    
1301    checkpoint53
1302    o stable checkpoint with up to date adjoint
1303      TLM tests only run for 1st grdchk at the moment. Its unclear if
1304      this is a code problem or a problem with resetting code for g_
1305      variables that is being autogenerated wrong.
1306      Otherwise:
1307       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1308       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1309         are both still in chaos following their security messes.
1310    
1311    checkpoint52n_post
1312    o various build (mostly genmake2) changes including:
1313      - ability to build/run more easily within Cygwin and MacOS X
1314      - more complicated Makefiles with a stronger dependence on Gnu Make
1315    o pkg/seaice modifications
1316      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1317        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1318        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1319      - changed proxy for geostrophic velocity and updated
1320        verification/lab_sea/results/* accordingly
1321      - removed ADI dynamic solver from pkg/seaice
1322      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1323        they caused a segmentation fault under certain circumstances
1324      - removed unused field WATR
1325    o bug fix in exf-package:
1326      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1327         now reflect that.
1328    o small fixes in the cal-package:
1329      - set reference date to first of January for the 'model'-calendar
1330      - failing of cal_CheckDate in cal_FullDate now actually results in a
1331        warning
1332    o small modifications in exf-package to increase flexibility:
1333      - change climtempfreeze from a constant to a runtime parameter that
1334        is specified in data.exf_clim (default = -1.9)
1335      - introduce runtime parameter windstressmax (default = 2.0) that is
1336        specified in data.exf
1337    o fix in pkg/thsice:
1338      - update Evap (Tsf changes) to be consistent with Latent heat flux
1339      - maintain snow precipitation unchanged (even if Tsf >=0).
1340     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1341    
1342    checkpoint52m_post
1343    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1344      this does not change any of the results, because myIter=0 in swfrac always
1345      lead to jwtype=2 (the default anyway), but the call makes little sense
1346      as a default
1347    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1348    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1349      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1350    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1351    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1352    o extending useSingleCpuIO option to work with new exch2 I/O format
1353      - old-style, missing-tile I/O is still accessible by defining CPP
1354        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1355    o monitor package can write to NetCDF files and/or STDOUT
1356    o fix re-definition bug in MNC_GRID_INIT_ALL()
1357    o doc/api_reference added
1358      - a framework for building an API Reference Manual using all
1359        the "protex" comments embedded in the code
1360      - see pkg/generic_advdiff, pkg/mnc for examples
1361    o MNC:
1362      - make myThid the last argument for all subroutines
1363      - new default for the grid files: NO halos
1364      - add useMNC and other run-time flags
1365      - separate per-file-group handling of the unlimited dimension
1366      - early initialization of MNC w/ flags read at the eeboot stage
1367        and lookup tables set in initialize_fixed
1368      - write all MNC output to a freshly-created directory
1369    o thermodynamics sea-ice (thsice) is now tested with testreport.
1370    o test exp. advect_cs: use the standard cs32 grid ; update output.
1371    o Added functionality to grdchk:
1372      pick global i,j,k position (or nearest wet) where to perform check.
1373    
1374    checkpoint52l_post
1375    o new land formulation:
1376      a) use ground enthalpy as prognostic variable to ensure exact
1377         energy conservation.
1378      b) account for water temperature and for latent heat of freezing
1379         in all processes (rain, run-off, ground storage)
1380      c) compute surface and ground temperature implicitly.
1381    o aim_v23 modification for new land model:
1382      a) Treat separately land / ocean / sea-ice surface fluxes
1383         to allow implicit computation of land & sea-ice surface temp.
1384      b) add snow precipitation.
1385    checkpoint52l_pre
1386    
1387    o fix problem (when 1 tile is empty) in min/max monitor.
1388    o fix bug in timeAve (u,vZetatave in common block)
1389    o no restoring terms under ice for pkg/seaice
1390    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1391    o bug fix for pkg/seaice pickups
1392    o change MNC call locations and add coordinate attributes
1393    o mask vorticity at the corner ; affects global_ocean.cs output
1394    o fix ini_curvilinear_grid ; test CS experiments with mpi
1395    o aim.5l_cs: modify sea-ice fraction input file ; update output
1396    o exf: Adding simple range check routine for exf fields after read
1397    
1398    checkpoint52k_post
1399    o removed top-level directory "diags"
1400      - we migrated these functions to pkg/timeave a long time ago
1401    o fixed bug introduced in pkg/monitor
1402    o accuracy ctrlprec = 32 insuffient for gradient checks using
1403      averaged fields (I/O via cost_averages)
1404      -> use ctrl.h in active_file*.F to control I/O precision.
1405    o paramter list of CALL ADTHE_MAIN_LOOP
1406    o added initial do_the_model_io to ecco
1407    o set all ...Freq to zero after cost_final
1408      taveFreq, dumpFreq, pChkptFreq
1409    o MAIN and ECCO differentiability restored
1410    
1411    checkpoint52j_post
1412    o fix nchklev in tamc.h for global_ocean...
1413    o Bringing flow and store directives up-to-date
1414    o Really weird thing!
1415      call do_the_model_io from the_main_loop with parameters
1416      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1417      TAF places a faulty re-call of initialise_varia
1418      after cost_final call which should not be there!
1419    checkpoint52j_pre
1420    
1421    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1422      error messages
1423    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1424    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1425      debug output
1426    o modfied mdsio_writefield.F to handle non-global files under exch2
1427    o update AIM Cubed-Sphere exp (aim.5l_cs):
1428      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1429    o update AIM Equatorial Channel exp:
1430      use standard aim_v23 pkg and change the SST fields to be more realistic.
1431    o globalFile now works with exch2
1432    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1433      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1434    o limit timeave output for hi-res integrations
1435    
1436    checkpoint52i_post
1437    o removed CPP_EEOPTIONS.h from verification/*/code
1438    o updated the tiling for global_ocean_pressure
1439    checkpoint52i_pre
1440    
1441    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1442      the old pkg/aim).
1443    
1444    checkpoint52h_pre
1445    o shortened offending lines in exch2_send_rx?.template
1446    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1447    o genmake2: add build & execute test for NetCDF code
1448    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1449      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1450    o added useSingleCPUIO flag to monitor.F and mon_out.F
1451    o added temporary hack for sea-ice dynamics on the cube:
1452      metric terms are ignored and it is assumed that
1453      there is no sea-ice on cube faces 1, 2, 4, and 5.
1454    
1455    checkpoint52f_post
1456    o added exch2 cube routines to pkg/exch2
1457    o modified hs94.cs-32x32x5 to use it
1458    o added new grid files to hs94.cs-32x32x5
1459    checkpoint52f_pre
1460    
1461    checkpoint52e_post
1462    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1463      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1464    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1465      to work with implicit vertical advection and AB ;
1466    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1467    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1468     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1469    checkpoint52e_pre
1470    
1471    o fix bug in impldiff when Nr=1 or Nr=2.
1472    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1473    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1474    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1475      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1476    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1477    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1478    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1479    
1480    checkpoint52d_post
1481    o re-tiled many expts to allow comparison in multi-processor mode
1482      - updated output accordingly
1483      - changed hs94.128x64x5 to use intial T from file rather than use the
1484        random number generator
1485    o add infrastructure in model routines for fizhi and gridalt packages
1486    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1487    o changes to permit hi-res, cubed-sphere, configuration
1488      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1489      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1490      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1491        of surface winds for the cube
1492      (A verification experiment, based on global_ocean.cs32x15, but with
1493       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1494       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1495       complete with example surface forcing files and matlab scripts to look
1496       at the output and compare it with that of global_ocean.cs32x15.)
1497    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1498       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1499       to conform to the common rule.
1500    o check-in the first version of the coupler + interfaces for multi-components
1501       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1502       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1503       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1504       - ocean and atmos. share the same horizontal grid (no interpolation).
1505       - exchanges between component and coupler is done in forward_step
1506    o new verification experiment, cpl_aim+ocn:
1507       coupled ocean - AIM atmosphere on cs32 grid.
1508    
1509    checkpoint52d_pre
1510    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1511    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1512    
1513    checkpoint52c_post
1514    o Fixing OPTIONS files for use of exf:
1515      - ALLOW_ECCO not needed
1516      - ECCO_CPPOPTIONS.h should not be included from
1517        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1518        as has been the case in the past
1519      - All cal/exf related options are currently set in
1520        single header file. Should remain so until we
1521        agree on a consistent new policy.
1522    o Removed all CPP options for cal package.
1523      cal has no more CPP options.
1524    o modified STOREs in GAD_ADVECTION
1525    o corrected key comp. for passkey
1526    
1527  checkpoint52b_post  checkpoint52b_post
1528  o new version: "thsice" of thermodynamic sea-ice pkg:  o new version: "thsice" of thermodynamic sea-ice pkg:
1529   - only 1 call from "forward_step"; conserve energy, fresh-water & salt.   - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
