5      ==============================      ==============================
6    
7    checkpoint58j_post
8    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
9      from file (collects calls previously in FORWARD_STEP)
10    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
11    o adjoint store dir. adjusted accordingly
12    o genmake2
13      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
14    
15    checkpoint58i_post
16    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
17      on wind stress (SEAICEstressFactor defaults to 1.)
18    o Total number of Timers is finite (<=40): comment out 2 non-essential one
19      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
20    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
21      on CS-grid: no longer loosing mass.
22    o exf & curvilinear-grid: no longer modify longitude xC & xG.
23    o pkg/ggl90: fix sloppy output and fix a bug
24    o pkg/seaice: added SEAICEuseEVPpickup parameter
25      - Set to false in order to start EVP solver with
26        non-EVP pickup files when using SEAICEuseEVP
27      - fix sign error in diffusion in seaice_calc_rhs
28    
29    checkpoint58h_post
30    * Modifications for bottom topography control
31      o replace hFacC by _hFacC at various places
32      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
33      o add non-self-adjoint cg2d_nsa
34      o update autodiff support routines
35      o re-initialise hfac after ctrl_depth_ini
36      o works for 5x5 box, doesnt work for global_ocean.90x40x15
37    * Adding verification for 5x5 box (4-layer) bottom topography control
38    
39    checkpoint58g_post
40    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
41       used for mean seasonal cycle, mean diurnal cycle); add an example
42       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
43    o pkg/ggl90:
44      - add parameter (minimum surface kinetic energy)
45      - fix bug (avoiding division by zero)
46    o couple pkg/thsice to pkg/seaice:
47      - modify advection in seaice to accomodate new scalar fields to be advected
48      - only muliDimAdection scheme work with seaice/thsice
49      - mapping of thsice-variables to seaice-variables, back and forth
50      - does not break the verification experiments, but does not give the
51        desired results either
52    o pkg/seaice
53      - make (default) second order advection a bit less confusing?
54    
55    checkpoint58f_post
56    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
57      to pkg/seaice):
58      - new routines thsice_map_exf and thsice_get_exf provide the interface
59      - add an additional formal parameter to thsice_solve4temp
60    o pkg/exf:
61      - add new fields wspeed, snowprecip (to be able to couple to thsice)
62      - correct Stefan-Boltzmann constant
63      - new parameter for longwave surface emittance
64      - separate some stuff from exf_bulkformulae into new routines  
65        exf_radiation, exf_wind
66      - add new parameters and constants: longwave emissivity for ocean, ice
67        and snow, evaporation parameters over ice
68      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
69        either wind from stress or stress from wind
70    o pkg/thSIce:
71    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
72    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
73       and THSICE_CALC_THICKN
74    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
75    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
76      to make debugging easier.
77    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
78    o pkg/bulk_force:
79      - clean-up comments and parameters ;
80      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
81    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
82      generate new output for test-experiment: aim.5l_cs.thSI
83    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
84      testreport accordingly
85    
86    checkpoint58e_post
87    o SEAICE_CGRID adjoint done
88    o R_STAR adjoint implemented.
89      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
90      * need to sort out init. of h0facc, etc.
91    o Make pkg/profile fully independent of ecco,cost, etc. stuff
92      to be able to use it in pure forward.
93    
94    checkpoint58d_post
95    o upgrade simple test-experiment to tutorial example:
96     step.1: duplicate the experiment and (step.2) will remove the old copy.
97      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
98      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
99      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
100      tutorial_global_oce_biogeo    <- copy of dic_example
101      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
102      tutorial_plume_on_slope       <- copy of plume_on_slope
103      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
104      tutorial_global_oce_optim     <- empty for now (David ?)
105      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
106     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
107    o correct a sign problem in cost_scat.F
108    o obcs and ptracers: fix boundary conditions for advections schemes
109      with larger stencil
110    o thsice adjoint: start
111    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
112      completeness
113    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
114      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
115    o ptracers adjoint:
116      * avoid extensive recomputatations
117      * fix missing re-init. of gptr (missed by TAF)
118    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
119      me to turn off the excessive output to STDOUT that this package produces
120    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
121      and add those terms in Vector-Invariant formulation.
122    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
123      if the control period (xx_hfluxperiod etc) is 0
124    o in profiles pkg, clean routines and fix details
125    o in ecco pkg, reading ssh data:
126      fix problem in case the model does not start at iter0=0
127    o fix mnc-pickup/restart for ptracers
128    o new package prifiles:
129      code to compute profile-based cost by Gael Forget
130      (modifs in ecco, ctrl, autodiff)
131    o Benign bug fix in initialization (spotted by M. Mazloff) of
132      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
133    
134    checkpoint58c_post
135    o adjoint: finish NLFS adjoint and provide reference output in
136      verification/global_ocean.90x40x15/results_ad_nlfs
137    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
138      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
139      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
140      with SEAICE_CGRID defined.
141    o move calendarDumps from "data" to "data.cal" and clean-up the code
142      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
143    o add useEXF & useCAL flags (for now, set in hard-coded way)
144    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
145      (were missing in NH mode, and wrong in quasihydrostatic mode).
146      waiting for Chris updated version of calc_gw to add those CALLs.
147    o fix bug in quasihydrostatic S/R ;
148      add a test for this option: global_ocean.90x40x15.qshyd
149    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
150      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
151    o add on/off flag useOffLine for package OFFLINE
152    o seaice:
153      - modify advection so that it works also on the C-grid
154      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
155        problem in multi-tile runs with C-grid
156      - add flags for clipping ice velocities and/or masking solver forcing
157      - fix drag (ocean on ice) formulation and a bug that caused noise in the
158        C-grid solver
159      - added a few comments to seaice_diffusion.F
160      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
161        are now exclusive)
162      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
163        required re-ordering the code a little:
164       + make DAIRN global variable (defined in SEAICE)
165       + move computation of the viscosities eta and zeta into a new separate
166         routine (because I need to recompute them in seaice_ocean_stress.F)
167    
168    checkpoint58b_post
169    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
170      update output.txt of exp. aim.5l_cs.thSI
171    o various mnc cleanups and improvements:
172      + shrink lookup tables by factor of ~4
173      + better error reporting when running out of lookup space
174      + able to handle longer path/file names (up to 500 chars)
175    o adjoint:
176      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
177      - TBD: "hidden" mom_vecinv recomp. in dynamics
178    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
179     (allow to differentiate between forcing components using new integer flags:
180      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
181     and add new flag to put Dissipation tendency out of Adams-Bashforth.
182    o ecco
183      - enable trend removal from SSH anomaly obs.
184    o adjoint
185      - a fix for PmEpR when #undef EXACT_CONSERV
186      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
187      - try to fix "hidden" recomp. in forward_step for NLFS
188        (NLFS seems broken sometimes after I checked it in)
189    o seaice:
190     - add c-grid version of the dynamic solver:
191       + three new routines that are the c-grid substitute lsr, dynsolver
192         and ostres
193       + put a few fields that were local to dynsolver into global common
194         blocks, so that I can move the computation of stresses etc into
195         seaice_lsr (saves coding but may break the adjoint).
196     - replace more hardwired parameters by runtime parameters
197     - add ice masks that mask the rhs of the implicit solvers where there
198       is no ice (commented out in seaice_dynsolver, because i am not sure
199       if this works properly), eventually this should replace the clipping
200       of ice velocities in seaice_dynsolver to +/-40cm/s.
201    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
202      include it only where its needed
203    o move balancing of fluxes before the call of external_forcing_surf
204    o seaice:
205      - correct units of turning angles (now they are really in degrees)
206      - move computation of GWATX/Y out of main routine into dynsolver
207      - initialize GWATX/Y in seaice_init
208    o Apply mask on Fresh-Water flux (needed for SSH forcing).
209      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
210    o seaice: add runtime flags for turning angles (default to zero)
211    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
212      and trend from exf forcing and ctrl control adjustments
213    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
214      (since checkpoint57x_post)
215    o change the default rotation period to 86164.s = the Earth rotation
216    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
217      and based on a reference stratification. Tested within hs94.cs-32x32x5.
218    o seaice advection: add code for choosing between the default (2nd order
219      central differences) and multiDim advection schemes provided by
220      pkg/generic_advdiff
221    o seaice:
222      - removed all references to SEAICE_GRID.h fields from
223        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
224        (cubed-sphere configuration will change a little)
225      - grid computations in seaice_init are obsolete now.
226      - cleaned up code a little so that is easier to read (hopefully).
227      - added new (better?) discretizations of default advection and diffusion
228        (turn on with SEAICEuseFluxForm)
229      - replace 1 in 3d global fields by kSurface in growth.F
230      
231    checkpoint58a_post
232    o seaice:
233      - bug fix in advect.F
234    o shelfice:
235      - separate shelfice load anomaly from pload (breaks with time
236        dependent forcing), => introduce constant field shelficeLoadAnomaly.
237        Its default is 0., but it may be computed more cleverly from (unknown)
238        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
239        done offline. A good approximation of the pressure load anomaly is
240        necessary to avoid large initial adjustment processes underneath
241        deep-reaching shelfice.
242      - small fix in ISOMIP shelfice_thermodynamics
243      - add more sophisticated thermodynamics of Hellmer (1989), this is
244        now the default
245      - give a few constants more intuitive names
246    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
247      if bulk formulae are used in long integration (especially EmPmR). Turn
248      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
249      if balancePrintMean, the imbalance that is substracted is printed to
250      STDOUT.
251    o fix bug (typo) in obcs_apply_eta.F
252    o add a new package shelfice which enables us to model the circulation
253      underneath shelf-ice with draughts of hundreds of meters.
254     - works
255     - to do: + include improved thermodynamics
256              + check whether kSurfC (from model/inc/SURFACE.h) can be used
257                instead of new field kTopC
258              + can we use topoFile, Ro_surf and existing code in ini_depth.F
259                instead of new field R_shelfIce and new code in ini_depth.F
260                and ini_mask_etc.F?
261              + adjust vertical mixing schemes?
262    o seaice pkg:
263     - add a cpp-flag to include a simple formula for a salinity dependent
264       freezing point of sea water at the surface
265     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
266       meridional stresses are now different (and hopefully correct)
267    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
268       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
269       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
270    o pkg/diagnostics: add options and parameters for regional-statistics
271       diagnostics ; define regions by reading a region-mask from a file
272       (might add other options later)
273    o pkg/bulk_force:
274     - add option and parameters to use AIM surface-flux formulae.
275     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
276       others forcing fields (defined in PARM05, parameter file "data") are loaded
277       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
278     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
279     - use the right EXCH call for uwind,vwind (to work on CS-grid).
280     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
281       and parameters (note: calcWindStress replaces .NOT.readwindstress).
282     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
283    
284    checkpoint58
285    o add "--embed-source" option to genmake2 which, when the supporting
286      tools can be compiled (as determined by genmake2) will turn on the
287      embed_files package which then embeds the entire MITgcm source code
288      (*.[fFhc] + Makefile) used for the build within the executable
289      - requested by CNH but off by default
290      - adds a paltry <9MB to the mitgcmuv executable in most cases
291      - only writes the output when useEMBEDSRC in eedata is true
292    o clean up 3-dim. relaxation codes:
293      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
294      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
295      * Thanks to Tom Haine for testing!
296    
297    checkpoint57z_post
298    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
299      affects output (@ truncation level) of exp. plume_on_slope ; updated.
300    o fix the pickup behavior for obcs in combination with ptracers
301    o fix a bug in ptracers_external_fields_load
302    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
303      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
304    o transfered surface NH pressure to eta field (if exactConserv).
305    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
306         and update lab_sea output.txt file.
307    o completing 3-dim. relaxation code: additional term
308         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
309      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
310      * At compile time, in "EXF_OPTIONS.h" set
311          #define  ALLOW_CLIMTEMP_RELAXATION
312          #define  ALLOW_CLIMSALT_RELAXATION
313      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
314          tauThetaClimRelax3Dim = 15552000.0,
315          tauSaltClimRelax3Dim  = 15552000.0,
316      * 3 cases:
317          1) Use a constant-in-time 3-dim. field
318          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
319          3) Real-time relax. to time-evolving prescribed field
320    o Adding Laplacian-type smoothness constraint on
321      initial and boundary (forcing) controls (ic, bc)
322      * enable at compile-time via
323        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
324      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
325      * Absolute scale somewhat unclear so far
326      * no area weighting was included since no other cost term does so far
327    
328    checkpoint57y_post
329    First step for a NLFS adjoint
330    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
331    o new init. routines for calc_r_star, calc_surf_dr
332    o still need to deal with ini_masks_etc
333    o testreport seemed happy
334    checkpoint57y_pre
335    
336    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
337    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
338    o add new offset feature to offline pkg (plus minor cleanup)
339    o cfc fixes for final year of integration
340    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
341      be in GCHEM_OPTIONS).
342    
343    checkpoint57x_post
344    o fix testreport Pb in multiple test experiment.
345    o cleanup our namelist syntax in verification:
346      - make it more F95 standards compliant (some work still needed)
347      - allows the vast majority of our tests to work with gfortran
348    o Non-Hydrostatic:
349     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
350     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
351    o Allow to apply AB on T,S rather than on AB(gT,gS):
352     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
353     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
354       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
355     - need a "clever" read_pickup to restart from the other AB formulation
356    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
357    o remove some unused variables (reduces number of compiler warnings)
358    o adjoint
359      * Disable useVariableViscosity for adjoint for time being
360        (there are a number of extensive recomputations)
361      * Initialize certain variables needed for adjoint
362    
363    checkpoint57w_post
364    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
365                 fix the singleCpuIO RS version of MDSWRITEFIELD
366       and add a WARNING if using globalFiles=T with multi-processors.
367    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
368      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
369    o tracer advection scheme:
370      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
371       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
372       was not very convenient).
373      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
374       (further tests needed for the implicit DST & Flux-Limiter schemes).
375    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
376      and sRef for convenience, handy, when you want to initialize
377      ptracers in a large domain with a constant non-zero value. Also,
378      untangle ptracers_init.F a little.
379    
380    checkpoint57v_post
381    o change dome exp. to use variable viscosity in side-drag terms.
382    o remove all the files from the cfc_offline test since they are now
383      incorporated into tutorial_cfc_offline which has been producing
384      identical results for a few days of testing
385    o add new parameter: sideDragFactor to enable half-slip-side BC
386      and change side-drag S/R to use viscosity from mom_calc_visc
387      (can switch back by setting sideDragFactor=0.); affects results at
388      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
389       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
390    o vorticity & strain are now computed without masking, to account for
391      no-slip-side BC in variable viscosity calculation ; mask is applied
392      anyway later on, before computing advection/coriolis terms.
393    o modify exp4 to test new obcs support for reading from external files
394      and for passive tracers
395    o fix behavior of ptracers_monitor when monitor output is written to a
396      netcdf-file; still not independent of monitor.F (writes in the same
397      file).
398    o change default value of tRef (put a uniform, meaningful value for ocean
399      & atmos) and initialize sRef (was missing, as Martin mentioned).
400    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
401      to be proportional to enstrophy dissipation length.  Thus,
402       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
403      This is now consistent with Smagorinsky and with the manual.
404    
405    checkpoint57u_post
406    o OBCS and PTRACERS: add open boundary support for passive tracers
407      - either use homogenous (pseudo) v.Neumann conditions or prescribe
408        OB-values from file; this is not different from the way theta and salinity
409        are treated
410      - however, Orlanski-radiation conditions are not supported, and the model
411        will stop if you use pTracers and Orlanski at the same time.
412      - beefed up the rountine obcs_external_fields_load: now only those open
413        boundary values are overwritten with values from files for which there
414        are really files, otherwise the OB-fields remain untouched. This makes
415        it possible to use different OBs at different ends of the domain (as
416        with EXF)
417    o reduce number of exch calls in shap_filt (s2).
418    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
419      truncation level) 4/5 MLAdjust test results (11&12 digits match).
420    
421    checkpoint57t_post
422    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
423    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
424      same truncation, independent of the face number: affects affects several
425      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
426    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
427      note that biharmonic viscosity + no-slip was not tested in any experiment.
428    o fix bug in non-linear free-surf side-drag ; generate new output for
429      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
430    o make mnc honor the writeBinaryPrec flag for most kinds of output
431    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
432    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
433      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
434    o add brackets in multi-terms sum to get same truncation, independent of
435      the face number (manage to get exactly same value of gU,gV at the cs-edge)
436      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
437    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
438      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
439      a maximum grid-scale Reynolds number.  Also, changes all length calculations
440      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
441      Suggested values of viscosity parameters found in mom_calc_visc.
442      Many new viscosity diagnostics available.
443    
444    checkpoint57s_post
445    o Add clearing-house for viscosity calculations, mom_calc_visc and
446      correct numerous bugs in LeithD and Smagorinsky discretizations.  
447      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
448      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
449      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
450      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
451      The Strain-Tension form is now called with useStrainTensonVisc=.true.
452      ViscAhStrain and viscAhTension are now retired.
453    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
454    o In response to JMC's bug report, genmake2 now ignores any soft-links
455      that it finds in the *current* directory when searching for files.
456      Soft-links found in any other source directories will still work as
457      they did before.
458    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
459      a C routine to unlimit the stack size
460    o mnc-ify pkg/aim snapshot vars
461    o mnc-ify pkg/land as requested by Daniel
462    o various changes to mnc including:
463      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
464      - output can now be grouped so that all files within a group
465          change the ITER portion of their names in lock-step together
466      - can now read ("global") PER-FACE (in addition to PER-TILE) files
467          and works with both EXCH1 and EXCH2 (but needs more testing)
468      - writing works for all verification test cases w/ g77 on Linux
469    
470    checkpoint57r_post
471    o make MNC variable initialization happen earlier
472    o add diagnostics for (almost) each term of the momentum Eq.
473    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
474    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
475    o remove MINIMAL_TAVE_OUTPUT option ;
476      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
477    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
478      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
479    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
480    o add time-dependent SST, SSS control
481    o cost terms in ecco/ modularized (new cost_generic.F)
482    o cost_averages routines are modularized (new cost_averagesgeneric.F)
483    o new infrastructure for seaice model vs. obs misfits in seaice/
484      * driver from the_main_loop.F is seaice_cost_driver.F
485      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
486      * gradient check in Exp. 6a of natl_box_adjoint/
487    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
488      (see README file)
489    
490    checkpoint57q_post
491    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
492    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
493      - bug was reported by Jean-Michel and Ian Fenty
494    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
495      update exp. cpl_aim+ocn output.
496    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
497      Needed for high-res. runs with large global files
498      to be able to limit tapelev size
499    o Changed some tests for adjoint:
500      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
501      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
502      * global_ocean.90x40x15/ back to default 3-level checkpointing
503    o Modifications to enable scripted COMMON to MODULE conversion
504      * verification/OpenAD/code/ has necessary scripts and description;
505      * converts, compiles and runs successfully;
506    
507    checkpoint57p_post
508    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
509    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
510      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
511    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
512    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
513      (was already the case for dissipation with mom_vecinv,
514       and also the case for grad.PhiHyd when staggered-timeStep)
515      This will allow to put dissipation out-off the AB time-stepping.
516     Unfortunately, affects truncation error. Update output of exp. that "fails"
517      (cg2d matching number) and leave the others for later: front_relax(10),
518      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
519      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
520    
521    checkpoint57o_post
522    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
523      (2) its ready to be documented during the 20050801 DocFest
524    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
525      for ideal_2D_oce and lab_sea on linux_ia32_g77
526    o set to #undef CTRL_SET_OLD_MAXCVARS_30
527      in global1x1_tot/code_seaice_adj to access indices 32, 33
528      (worth another tag)
529    
530    checkpoint57n_post
531    o adding precip control xx_precip 32
532    o adding swflux control xx_swflux 33
533    o Replacing 10 forcing penalty cost routines by 1 generic.
534    o Implementing partitioning in time-mean and variable adjustment
535      for atmos. state.
536    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
537    o in natl_box_adjoint:
538      * updated exp 1 to 10
539        (but does not have time-mean vs. variable split results yet)
540    o updated global1x1/*_seaice_adj/
541      to incorporate latest changes
542    o enable useSingleCpuIO for mdsio vector routines
543      (applies in particular to tapelev I/O)
544    o removed inefficient K-loop in all active_file*control*.F
545    
546    checkpoint57m_post
547    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
548      and advect_cs (use EXCH-2 and standard cs-32 grid files).
549    o pkg/exch2: filling of face-corner halo regions is optional
550      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
551    
552    checkpoint57l_post
553     tag before updating tutorials (pre-release-2)
554    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
555       for output and interpolation of input fields onto model grid)
556    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
557       Affects results of exp. rotating_tank ; update output.txt.
558    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
559          and taking the square quantity and/or using a fraction-weight field.
560    o fix aim_diagnostics_init.F mate numbers.
561    o add mnc output capability to diagnostics/diagstat and update
562      our cvsignore files for the ACSII output generated
563    
564    checkpoint57k_post
565    o lab_sea now uses diagnostics package and provides a suite of
566      new EXF diagnostics output.
567    
568    checkpoint57j_post
569    o exf
570      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
571        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
572        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
573      * extended diagnostics output
574        - now includes all EXF variables
575        - hs, hl moved to common block
576        - separate S/R for diagnostics, called after ctrl vector is added
577        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
578        - EXFqnet contains true Qnet (i.e. includes qsw)
579      * updated verif. lab_sea, global_with_exf
580      * Rearranging hflux (exf_mapfields -> exf_getforcing)
581        to ensure that diagnostics sees a true EXFqnet
582    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
583    o diagnostics pkg: change pointers so that 1 diagnostic can be used
584      several times with different frequencies.
585    o mnc-ify the thsice package as requested by Daniel Enderton
586      - the monitor--MNC output needs work
587      - many attributes need to be added (most are currently blank)
588    o mnc-ify theaim_v23 package as requested by Daniel Enderton
589      - many attributes need to be added (most are currently blank)
590    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
591    o add Sadourny like discretization to the 4th.O vorticity advection scheme
592    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
593      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
594         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
595    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
596     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
597    
598    checkpoint57i_post
599    o Diagnostics package was changed: diagnostic allocation is now deactivated
600      by setting an empty file name in the namelist (used to be by setting 0 frequency)
601    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
602      add 1rst Order upwind vertical Shear.
603    o add a quick fix for A/B checkpointing in OFFLINE mode
604    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
605      end-run around the C/Fortran linking horror in eesup/src/timers.F
606    o added pkg/runclock: allows user to terminate run based on wall clock
607    o added non-hydrostatic scaling parameter: nh_am2
608    o pkg/my82: futile attempt to make results compiler-independent by adding
609      some "_d 0", etc. no effect.
610    o for mnc output, fill the 'T' coordinate var with myTime and create a
611      separate 'iter' variable for iteration count
612    o pkg/diagnostics:
613      add new capability: output of Global/Regional & per-level statistics ;
614      tested against monitor output (including land & thSIce) on various exp.
615    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
616    
617    checkpoint57h_done

619      data.diagnostics, data.gchem, data.ptracers) is done.
620    
621    o pkg/diagnostics: prepare for Global/Regional statistics.
622      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
623    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
624      and rename it: DIFFERENT_MULTIPLE
625    
626    checkpoint57h_post
627    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
628    o pkg/diagnostics: change output frequency, now in seconds (instead
629      of Nb of iterations). This requires to change data.diagnostics.
630    checkpoint57h_pre
631    
632    o in mnc, let the user create the output dir if both mnc_outdir_date
633      and mnc_outdir_num are false
634    o add fflags() to pkg/diagnostics which allows one to specify, on a
635      per-file basis, the file precision [default behavior is unchanged]
636    o added diagnostics to pkg/kpp, including computation of mixed layer
637      depth based on a temperature/density criterion
638    o updated verification/natl_box to test the new pkg/kpp diagnostics
639    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
640    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
641    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
642      not mnc -- this mistake was found by JMC and is now corrected
643    
644    checkpoint57g_post
645    o add Adams-Bashforth 3rd Order time stepping:
646      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
647      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
648    checkpoint57g_pre
649    
650    o make lambda[Theta,Salt]ClimRelax spatially varying
651      (default remains spatially uniform constant based on tau)
652    o added new control variables
653      * init. uVel, vVel, etanN
654      * lambda[Theta,Salt]ClimRelax
655    o separate masks used for ctrl_pack/unpack 'from write_grid' output
656      (suggested by G. Forget)
657    
658    checkpoint57f_post
659    o add parameter "baseTime" = model base time = time at iteration zero
660      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
661      account for baseTime shift
662    o move Coriolis arrays from PARAMS.h to GRID.h
663    checkpoint57f_pre
664    
665    o mnc-ifying the seaice package

668    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
669    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
670      as well as grad(vort3).  Made it compatible with both approximate form
671      for the cubed sphere and full form of these gradients.  Added flag
672      useFullLeith to select between approximate and full form.  
673    o add "d0" in getcon.F to reduce differences between compilers/platforms
674      update output.txt of exp. fizhi-gridalt-hs
675    o change port_rand funtion to allow to set the seed.
676    o fix obscure MNC bug involving conversion between reals and integers
677      - it caused no problems with certain (eg. gcc, ifc) compilers but the
678        new version is now more standards-compliant
679    o adjoint-related modifications
680      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
681      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
682      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
683    
684    checkpoint57e_post

689      update output.txt of exp. fizhi-gridalt-hs
690    o add more "Z" dimensions and associated coordinate vars to MNC
691    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
692    o parameter calendarDumps: when set, approximate months (30-31 days) and years
693      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
694      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
695      months and years.  Requires pkg/cal.
696    o diagnostics: add pickup functionality
697      - off by default for backwards compatibility
698      - current version only uses MDSIO -- MNC will be added
699    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
700    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
701    
702    checkpoint57d_post
703    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
704    o modify verification/ideal_2D_oce so that it tests the creation of mnc
705      output from the diagnostics package
706    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
707    o make genmake2 more portable by using ".$FS" instead of ".f" for more
708      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
709    o add coordinate variables to the MNC output from the diagnostics package
710    o change MNC-flags default value: true when useMNC=TRUE
711    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
712      the ability (off by default) to read the grid information using MNC
713    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
714    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
715    o do snap-shot diagnostics at the middle of the time-interval (instead of
716      at the end).
717    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
718      new test for AIM with thSIce + slab-ocean
719    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
720    o move state variable diagnostics to the beginning of the time step ;
721      (note: still needs some work specially for snap-shot diagnostics)
722      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
723    
724    checkpoint57c_post
725    o Change testing option (-ieee) to get closer agreement between g77 & ifort
726    o generate new output.txt files on faulks with g77 & the new -ieee option
727    checkpoint57c_pre
728    
729    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
730      update output.txt of exp. global_ocean.90x40x15
731    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
732      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
733    o add saltFlux(+File) forcing capability with periodicExternalForcing
734    o allow to use pkg diagnostics for GM-Redi & ThSIce output
735    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
736    o improvements for the MNC output from DIAGNOSTICS:
737      - correct handling of the unlimitied dimension
738      - all dims now have associated coordinate variables
739      - variables located at U, V, and Corner ("Z") points are now written
740        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
741        *all* data points are output
742    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
743    o added pkg/seaice/seaice_monitor.F
744    o mdsio_readfield.F can now read files visible only to master MPI process.
745    o pkg/seaice: some test code for ice-modified ocean stress
746    o exf_getffields interpolation defaults to bilinear for all scalar forcing
747      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
748      spurious negative numbers for precipitation and humidity.  Will cause
749      some small numerical differences for integrations using pkg/exf/exf_interp.F.
750    o pkg/ctrl/
751      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
752        May be enabled via doPackDiag
753      *  introduce z-scaling of
754         + gradient (doZscalePack) and
755         + control (doZscaleUnpack)
756    o pkg/mdsio/
757      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
758      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
759    
760    checkpoint57b_post
761    o simplify options in diagnostics_fill arguments (remove weird combinations)
762    o fix MNC coordinate variables so that they now contain per-face index
763      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
764      general, EXCH2 grids are only aligned to a "local" coordinate system
765    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
766    o Implement instantaneous output within pkg diagnostics:
767      setting a negative frequency in data.diagnostics produces
768     "snap-shot" output (as opposed to time-average if freq > 0)
769    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
770      NOTE: change ptracer diagnostics name: use 2 characters to work with
771            more than 9 tracers. Add also diagnostics of advect & diffus flux.
772    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
773      becomes the coordinate variable for the 'T' dimension
774    o add CF-style coordinate variables to MNC
775      - just a first cut:  numbers are meaningless on the cubesphere and
776        missing along the T axis but otherwise it works!
777    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
778    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
779    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
780      this is based directly on what the model compute, so that the content of
781      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
782    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
783    o clean up build options files for SunOS, in particular
784      - remove -traditional from xmakedepend
785      - change -xarch=v9 to -xarch=native for f77
786      - restore use of make (not gmake)
787      - add CC=gcc if using g77
788    o changes per discussion of AM, JMC, & EH3 today:
789      - move redundant "grid" variables out of "state" -- in preparation of
790        creating proper CF-style coordinate variables and in recognition
791        that any/all grid variables can be easily copied (eg. w/NCO) from
792        the grid files into any of the other NetCDF files
793      - *always* output grid variables with MDSIO (this will eventually be
794        changed)
795      - output MNC grid file if useMNC is true
796    o every instance of _END_MASTER() has been found and replaced with
797      _END_MASTER( myThid ) in order to satisfy certain picky Sun
798      preprocessors
799    o re-arrange diagnostics pkg initialisation:
800     - allow each package to extend the available diagnostics list
801     - add some checking and fix small problems (multi-threaded, ...)
802     - new S/R diagnostics_fill (replace fill_diagnostics):
803       look through the short list of active diag. (instead of the long list)
804       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
805    
806    checkpoint57a_post
807    o this set of changes restores TAMC compatibility
808      tested for global_ocean.90x40x15 adjoint on trough
809      (what a pain)
810    
811    checkpoint57a_pre
812    o some modifs in tools/build_options for sunos
813    o call ctrl_pack for ctrl at end for optimcycle=0
814    
815    checkpoint57
816    o add horizontal bi-harmonic viscosity for vertical velocity
817      - new parameter viscA4W (defaults to viscA4)
818      - affects only non-hydrostatic code
819      - to be done: no-slip lateral boundary conditions
820    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
821    o implement Implicit Vertical advection for pTracers
822    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
823      (implemented also for implicit vertical diffusion & advection)
824    o OBCS: extend application of tracer open boundary conditions
825      to a strip beyond the boundary of width Olx/Oly
826    o add call monitor to TAF set of required calls (flow directives)
827      and include in natl_box_adjoint
828    o untangle a few ifdefs related to cost, ctrl, autodiff
829      untangel a few ALLOW_ECCO_OPTIMIZATION
830    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
831      (theta2, salt2 in ecco_cost_weights)
832    
833    checkpoint56c_post
834    o OBCS as control variables
835      - update ctrl_ad_diff.list, obcs_ad_diff.list
836      - remove balance of obcs controls from default
837      - fix index bug nobcs in ctrl_init
838      - fix dummy fields filen in ctrl_pack
839      - add dummy weights for obcs
840    o lsopt: comment out fort.94 output
841    o optim:
842      - remove unnecessary header files
843      - adjusted namelists
844      - add xerbla.F to Makefile
845    o exf:
846      - multiple modifications of exf_check_range
847      - unit change in exf_init_runoff from [m/year] to [m/s]
848    o mdsio:
849      - i/o-vector change debugLevel from debLevA to debLevB
850    
851    checkpoint56b_post
852    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
853      is called from DO_THE_MODEL_IO
854      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
855      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
856      - clean up PTRACERS_WRITE_TIMEAVE a little
857    o add another verification experiment that tests both the cfc-pkg and
858      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
859      reactive tendencies treated inline with regular timestepping
860    o testreport previously did a lousy job of comparing small numbers, so
861      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
862      implemented in the little c-progam tmp_cmpnum.c which is embedded in
863      testreport.
864    o ptracers_monitor: bug fix for MPI
865    
866    checkpoint56a_post
867    o GCHEM: finish reorganizating the package
868      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
869        (introduces another 3D-array for each passive tracer, but only if
870        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
871        gchemTendency is not needed because the timestep is done separately)
872      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
873      - GCHEM is now---more or less cleanly---separate from PTRACERS
874      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
875        so clear to me how that should be done in a general way.
876    o CFC: improve formatting of output in CFC_ATMOS
877    o PTRACERS:
878      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
879        that ALL experiments with ptracers enable can be checked. This makes
880        GCHEM_MONITOR obsolete.
881      - include a runtime parameter PTRACERS_monitorFreq that defaults to
882        monitorFreq
883      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
884    o add PTRACERS (PTR0[1-5]) to testreport output
885    o exf_check_range:
886      * default changed to .TRUE.
887      * will check values for niter0 if debLevA, every timestep if debLevB
888      * STOP in exf_check_range if 'out of range'
889      * range chosen generous to allow for potential extema
890      TBD: a version with stricter range
891           permitted range would be runtime parameters
892    o GMredi:
893      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
894      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
895      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
896    o GCHEM:
897      - move call to GCHEM_FORCING_SEP, so that it is now called before
898        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
899      - introduced a useGCHEM runtime flag and applied it everywhere.
900      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
901        this flag is now only visible within GCHEM-pkg routines.
902      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
903        be replaced by a 3D array that is computed before thermodynamics; for
904        this, the tracer ID iTracer had to be included into the parameter list
905        of ptracers_forcing
906      - set up forward_step to call gchem_forcing, that will replace
907        gchem_forcing_int in ptracers_forcing
908      - cleaning up
909    o small cleaning of exch2: remove files that are also in eesupp/src
910    
911    checkpoint56
912    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
913    o mnc: cleanup "full" files--fixes out-of-memory problem
914    o ECCO-GODAE
915      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
916      * fully merged and updated from SIO code
917        windstress sign change affects
918        - exf_inscal_[u/v]stress
919        - sign of xx_tau[u/v] adjustments
920        - signs in cost_scat
921      * ctrl_get_gen: avoid update of tau[u/v] for first few days
922      * natl_box_adjoint updated and compressed
923      * 2-level checkpoint switch added
924        (tested in EXP. 1 of natl_box_adjoint)
925      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
926    o SVD
927      * first complete, non-hacked version for SVD calculations
928      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
929        performed via direct access files admtlm_vector.it????
930        (via ctrl_[un]pack)
931      * optimcycle is used for ARPACK iteration counter
932        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
933      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
934        and add linear transforms where necessary
935      * controls are initial/final SST, SSS (can be extended; need to check
936        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
937    o mdsio: filename info to both stderr, stdout
938    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
939      from sign change
940    
941    checkpoint55j_post
942    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
943      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
944    o add consistent build directories and .cvsignore files to verification
945    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
946    o make all subroutines 30 or less characters in length for certain older
947      compilers to work (a thorough search only turns up two routines in
948      pkg/ptracers)
949    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
950      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
951    
952    checkpoint55i_post
953    o change arrays for total vertical diffusivity (2.D if explicit,
954      3.D if implicit) ; each ptracer uses its own background value.
955    o added mnc/NetCDF output capability to ocn_compon_interf
956      - added bits to verification/cpl_aim+ocn so that it can run on
957        ITRDA and other clusters without the mpirun "-wd" option
958    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
959      configuration
960    o give MNC the ability to create additional files rather than
961      exceeding a specified file size limit "MNC_MAX_FILESIZE"
962      - the default is just less than 2GB which is a practical limit
963        on many systems
964    o Compute the non-local term using either KPP vertical diffusivity (=default)
965       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
966    
967    checkpoint55h_post
968    o add verification test "vermix"
969    o remove all the *_ioinc flags and replace with the single global
970      outputTypesInclusive flag
971    o allow to set a vertical profile of vertical diffusivity for T & S
972    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
973    o useMNC moved from data.mnc to data.pkg
974    
975    checkpoint55g_post
976    o Renaming carbon AD experiments to comply with testreport conventions
977    o Updating adjoint of Held-Suarez hs94.1x64x5
978    o Fixing directives for non-ECCO forward_step, after ECCO directives
979      have been fixed to avoid recomp. of do_oceanic_phys
980      Works well for global_ocean.90x40x15,
981      but recomp. issue remains for carbon
982    o Updating adjoint output for natl_box_adjoint after
983      pkg/ecco has been modified (see taga c55d_post)
984    
985    checkpoint55f_post
986    o rename to timeave_init_fixed
987    
988    checkpoint55e_post
989    o some delicate re-shuffle of store directives to avoid one
990      extra call of do_oceanic_physics
991      affects ecco_the_main_loop.F, do_oceanic_physics.F
992      checkpoint_lev1_directives.h
993    o NB: this may break global_ocean adjoint temporarily,
994      but it is clear how to fix it. Will do later, need this now.
995    
996    checkpoint55d_post
997    o ECCO specific cost function terms (up-to-date with 1x1 runs)
998    o ecco_cost_weights is modified to 1x1 runs
999    o modifs to allow observations to be read in as
1000      single file or yearly files
1001    o enable to read exf forcing fields as either
1002      single file or yearly files (flag useExfYearlyFields)
1003    checkpoint55d_pre
1004    
1005    o switch between 2-level and 3-level checkpointing
1006    o add ability of MNC to write local and "partial" (eg. 2D slices where
1007      the full 3D field is never actually stored) arrays to NetCDF files
1008      with the correct (that is, the complete multi-dimensional) set of
1009      array indicies
1010      - used in mom_vecinv() to write the diagFreq output
1011      - tested (demonstrated) in verification/aim.5l_cs
1012    o further mnc-ification
1013      - add verification/lab_sea to the list with mnc setups
1014      - fix undefined mnc v-names in cd_code
1015      - add kpp to mnc output (both snapshot and timeave)
1016    o non-hydrostatic code
1017      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1018        in calc_gw.F
1019      - defaults to viscAh
1020      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1021        friction or Leith) in non-hydrostatic mode, as long as there is
1022        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1023    o pkg/cost
1024      extend simple cost functions to treat time mean quantities
1025      (T,U,V) via cost_accumulate_state from cost_tile
1026    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1027        be 2 times larger than the minimum size the advection scheme requires.
1028        now get a perfect conservation of salt in advect_cs test-exp (updated)
1029    o GGL90 (Gaspar's TKE mixed layer)
1030      - add horizontal diffusion of TKE, requires exchanges in
1031        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1032        default. In OPA there is no horizontal diffusion of TKE but the
1033        mixing coefficients are computed from a horizontal average of TKE of
1034        6 points or so. I think that diffusion has a little more physical
1035        justification.
1036      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1037        was in vain)
1038      - mask tke-variable in ggl90_init
1039    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1040    o fix biharmonic diffusion on CS-grid.
1041    o more obcs stuff
1042      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1043        for reading boundary values. This routine is called from
1044        obcs_prescribe_read
1045      - updated obcs_check
1046      - changed sponge layer relaxation parameter units for days to seconds
1047      - turned off sponge layer by default
1048      - changed argument list of OBCS_CALC to myTime+deltaTclock
1049      - fixed about 35 bugs in obcs_external_fields_load
1050    
1051    checkpoint55c_post
1052    o obcs stuff
1053      - new runtime flags useOBCSprescribe, useOBCSbalance
1054      - re-arranged obcs_calc
1055      - moved exf_getobcs to obcs_prescibe_read
1056        obcs_prescibe_read is called after ORLANSKI stuff
1057        and independent of it (executable can contain all).
1058      - updated obcs_check
1059      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1060        These may be necessary only if tangential velocities are
1061        prescribed at OB, not sure, needs testing.
1062    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1063      which simplifies the calls and passes the ifc check-bounds test
1064    
1065    checkpoint55b_post
1066    o add a 2D scalar, Z location, exchange_2 routine.
1067    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1068      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1069      affects advect_cs results (for the wrong reason): update output.txt
1070    o use a more standard discretization for biharmonic viscosity ;
1071     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1072      affects results of dome set-up: update output.txt
1073    o fix gad_advection.F (CubedSphere part), back to version 1.23
1074    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1075    
1076    checkpoint55a_post
1077    o merged code to
1078      * prescribe/read time-dependent open boundaries
1079        (works in conjunction with exf, cal)
1080      * sponge layer code for open boundaries
1081      * each boundary N/S/E/W now has its own CPP option
1082        (healthy for the adjoint)
1083    
1084    checkpoint55
1085    o up-to-date adjoint of previous breaks
1086      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1087      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1088      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1089      - carbon: * remove tr1-related adjoint verification
1090                * add ptracer as control variable
1091    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1092      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1093    
1094    checkpoint54f_post
1095    o in verification/carbin/ remove experiment related to
1096      ALLOW_PASSIVE_TRACER (array tr1 etc)
1097      code_ad/ input_ad/ results_ad
1098    
1099    o add two new packages
1100      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1101        + subject to optimization (memory)
1102      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1103        + subject to reordering (many GOTOs in the original code)
1104        + so far opps is called for every (i,j) point, and then operates in
1105          the vertical; one may want to reorder the scheme in order operate in
1106          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1107          fields)
1108    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1109      - all verification tests compile and run with linux_ia32_g77
1110      - defaults are compatible with current input files--nothing
1111        should change if you were not previously using MNC
1112      - MNC output has been added in numerous places (eg. timeave)
1113        but there are still a few writes not yet do-able with MNC
1114        (this is in progress)
1115      - flags now allow for either/or/both use of MDSIO and MNC and
1116        documentation will soon follow
1117      - numerous small formatting cleanups for ProTeX
1118    o add version info (via BUILD_INFO.h) to MNC and stdout
1119    
1120    checkpoint54e_post
1121    o add two new packages
1122      - pp81 (Packanowski and Philander, 1981), Richardson number and
1123        stratification dependent mixing
1124      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1125      - these scheme operate in a similar manner as KPP (without ghat, of
1126        course), however there is only one diffusivity that is used for both
1127        temperature and salinity (and passive tracers)ç
1128    o add offline package
1129    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1130      provided by Stephanie Dutkiewicz
1131    o genmake2: add ability to search for C compilers and cleanup test output
1132      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1133    
1134    checkpoint54d_post
1135    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1136    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1137      leading to additional shift by 5 days each year of integration
1138       (i.e. leading to considerable offset over the years)
1139    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1140    o start with no AB and no initial filtering (staggerTimeStep):
1141      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1142    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1143      (external loading & cpl import/export stay in forward_step.F)
1144    o update coupling interface to work with new staggerTimeStep
1145    o change MDSIO ptracers_pickup.
1146    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1147    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1148    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1149    
1150    checkpoint54c_post
1151    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1152      this affects (truncation error) output.txt of test-exp:
1153       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1154    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1155    o change Qnet to always be the net heat flux, (+upward).
1156      affects (truncation error) output of natl_box exp.: updated
1157    o define the max number of passive tracers in PTRACERS_SIZE.h
1158    o start to test mnc routinely in exp0
1159    o add sea-ice loading (sIceLoad) as a new forcing field.
1160    
1161    checkpoint54b_post
1162    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1163       impressive on Altix and Opteron systems)
1164    o diagnostics can now write NetCDF files through the mnc package
1165    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1166    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1167    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1168      affects (truncation error) output of lab_sea & natl_box exp.: updated
1169    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1170    
1171    checkpoint54a_post
1172    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1173    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1174    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1175    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1176      + internal_wave (shift in writing cg2d_ini_res)
1177    checkpoint54a_pre
1178    
1179    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1180      - modified verification/lab_sea and natl_box_adjoint accordingly
1181    
1182    checkpoint54
1183    checkpoint53g_post
1184    o prepare splitting of thermodynamics: store convect.counter in common block
1185    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1186      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1187    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1188    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1189    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1190    o restore adjointability
1191    
1192    checkpoint53f_post
1193    o modifications that affect AIM experiment results (update output.txt):
1194      - no advection of S at top interface Nr (pkg/generic_advdiff)
1195      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1196    o AIM pkg:
1197      - include stability function into surf.Flux derivative relative to Tsurf
1198      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1199    
1200    checkpoint53e_post
1201    o merged cylindrical coord configuration
1202    o added rotating_tank experiment
1203    checkpoint53e_pre
1204    
1205    checkpoint53d_post
1206    o faulks upgraded: re-generate output.txt that have changed:
1207       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1208    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1209    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1210    o added Sadourny discretization of Coriolis
1211      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1212      - re-enabled use of omega3 (useAbsVorticity)
1213    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1214      vector-invariant equations
1215      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1216    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1217      hopefully without new bugs
1218      - still to do: biharmonic friction for non-hydrostatic w
1219    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1220    o regenerated output for global_ocean_ebm (using -ieee)
1221    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1222      of mom_common/
1223      - simple re-arrangement of instructions within computing loop
1224    checkpoint53d_pre
1225    
1226    checkpoint53c_post
1227    o new version of coupler for AIM+thSIce and Ocean models
1228     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1229     - land: change Evaporation of snow
1230     - aim with thSIce: fix bug in snow-precip.
1231    o changes to calc_gw.F
1232     - bug fix for w^2 term near the bottom boundary
1233     - (hopefully) improve the lateral slip boundary condtions for use with
1234        partial/looped cells
1235      - because the bug fix changes two verification experiments anyway (exp5
1236        and plume on slope), change the lateral boundary condition from half slip
1237        to the value of no_slip_sides
1238    o ebm package wasnt quite up to the parallel task. Fixed that.
1239    o Adjoint of EBM package + verification
1240      * TLM OK
1241      * ADM not sufficient accuracy yet (needs further testing)
1242    
1243    checkpoint53b_post
1244    o Commiting new energy balance model to repository
1245      * package is pkg/ebm
1246      * verif. is verification/global_ocean_ebm
1247      * references are in ebm_driver.F
1248    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1249    C        Global thermohaline circulation. Part I:
1250    C        Sensitivity to atmospheric moisture transport.
1251    C        J. Climate 12(1), 71-82
1252    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1253    C        Global thermohaline circulation. Part II:
1254    C        Sensitivity with interactive transport.
1255    C        J. Climate 12(1), 83-91
1256    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1257    C        Destabilization of the thermohaline circulation
1258    C        by atmospheric eddy transports.
1259    C        J. Climate 7(12), 1870-1882
1260    o Will need long integration testing.
1261    checkpoint53b_pre
1262    
1263    o created pkg/mom_common in preparation for variable viscosity code
1264    o renamed and split ini_mnc_io
1265    o pkg/land: only liquid water can diffuse or run-off
1266    o AIM using land: soil wetness availability account for snow
1267    o added printMapIncludesZeros to EEPARMS namelist
1268    
1269    checkpoint53a_post
1270    o restore TAMC compatiility for exf_constants.h
1271      (no usage of _d in .h)
1272    o Additional storing in KPP in an attempt to fix
1273      TAMC problem with adjoint of KPP code.
1274      (no success...)
1275      Identical code works fine with TAF.
1276    o Fixed verification/natl_box_adjoint experiments.
1277      Initial conditions for Experiments 4 and 5 are now
1278      set to "SEAICE_initialHEFF=0", which is more reasonable,
1279      and hence gives results closer to that of Experiment 2.
1280      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1281    
1282    checkpoint53
1283    o stable checkpoint with up to date adjoint
1284      TLM tests only run for 1st grdchk at the moment. Its unclear if
1285      this is a code problem or a problem with resetting code for g_
1286      variables that is being autogenerated wrong.
1287      Otherwise:
1288       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1289       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1290         are both still in chaos following their security messes.
1291    
1292    checkpoint52n_post
1293    o various build (mostly genmake2) changes including:
1294      - ability to build/run more easily within Cygwin and MacOS X
1295      - more complicated Makefiles with a stronger dependence on Gnu Make
1296    o pkg/seaice modifications
1297      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1298        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1299        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1300      - changed proxy for geostrophic velocity and updated
1301        verification/lab_sea/results/* accordingly
1302      - removed ADI dynamic solver from pkg/seaice
1303      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1304        they caused a segmentation fault under certain circumstances
1305      - removed unused field WATR
1306    o bug fix in exf-package:
1307      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1308         now reflect that.
1309    o small fixes in the cal-package:
1310      - set reference date to first of January for the 'model'-calendar
1311      - failing of cal_CheckDate in cal_FullDate now actually results in a
1312        warning
1313    o small modifications in exf-package to increase flexibility:
1314      - change climtempfreeze from a constant to a runtime parameter that
1315        is specified in data.exf_clim (default = -1.9)
1316      - introduce runtime parameter windstressmax (default = 2.0) that is
1317        specified in data.exf
1318    o fix in pkg/thsice:
1319      - update Evap (Tsf changes) to be consistent with Latent heat flux
1320      - maintain snow precipitation unchanged (even if Tsf >=0).
1321     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1322    
1323    checkpoint52m_post
1324    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1325      this does not change any of the results, because myIter=0 in swfrac always
1326      lead to jwtype=2 (the default anyway), but the call makes little sense
1327      as a default
1328    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1329    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1330      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1331    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1332    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1333    o extending useSingleCpuIO option to work with new exch2 I/O format
1334      - old-style, missing-tile I/O is still accessible by defining CPP
1335        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1336    o monitor package can write to NetCDF files and/or STDOUT
1337    o fix re-definition bug in MNC_GRID_INIT_ALL()
1338    o doc/api_reference added
1339      - a framework for building an API Reference Manual using all
1340        the "protex" comments embedded in the code
1341      - see pkg/generic_advdiff, pkg/mnc for examples
1342    o MNC:
1343      - make myThid the last argument for all subroutines
1344      - new default for the grid files: NO halos
1345      - add useMNC and other run-time flags
1346      - separate per-file-group handling of the unlimited dimension
1347      - early initialization of MNC w/ flags read at the eeboot stage
1348        and lookup tables set in initialize_fixed
1349      - write all MNC output to a freshly-created directory
1350    o thermodynamics sea-ice (thsice) is now tested with testreport.
1351    o test exp. advect_cs: use the standard cs32 grid ; update output.
1352    o Added functionality to grdchk:
1353      pick global i,j,k position (or nearest wet) where to perform check.
1354    
1355    checkpoint52l_post
1356    o new land formulation:
1357      a) use ground enthalpy as prognostic variable to ensure exact
1358         energy conservation.
1359      b) account for water temperature and for latent heat of freezing
1360         in all processes (rain, run-off, ground storage)
1361      c) compute surface and ground temperature implicitly.
1362    o aim_v23 modification for new land model:
1363      a) Treat separately land / ocean / sea-ice surface fluxes
1364         to allow implicit computation of land & sea-ice surface temp.
1365      b) add snow precipitation.
1366    checkpoint52l_pre
1367    
1368    o fix problem (when 1 tile is empty) in min/max monitor.
1369    o fix bug in timeAve (u,vZetatave in common block)
1370    o no restoring terms under ice for pkg/seaice
1371    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1372    o bug fix for pkg/seaice pickups
1373    o change MNC call locations and add coordinate attributes
1374    o mask vorticity at the corner ; affects global_ocean.cs output
1375    o fix ini_curvilinear_grid ; test CS experiments with mpi
1376    o aim.5l_cs: modify sea-ice fraction input file ; update output
1377    o exf: Adding simple range check routine for exf fields after read
1378    
1379    checkpoint52k_post
1380    o removed top-level directory "diags"
1381      - we migrated these functions to pkg/timeave a long time ago
1382    o fixed bug introduced in pkg/monitor
1383    o accuracy ctrlprec = 32 insuffient for gradient checks using
1384      averaged fields (I/O via cost_averages)
1385      -> use ctrl.h in active_file*.F to control I/O precision.
1386    o paramter list of CALL ADTHE_MAIN_LOOP
1387    o added initial do_the_model_io to ecco
1388    o set all ...Freq to zero after cost_final
1389      taveFreq, dumpFreq, pChkptFreq
1390    o MAIN and ECCO differentiability restored
1391    
1392    checkpoint52j_post
1393    o fix nchklev in tamc.h for global_ocean...
1394    o Bringing flow and store directives up-to-date
1395    o Really weird thing!
1396      call do_the_model_io from the_main_loop with parameters
1397      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1398      TAF places a faulty re-call of initialise_varia
1399      after cost_final call which should not be there!
1400    checkpoint52j_pre
1401    
1402    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1403      error messages
1404    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1405    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1406      debug output
1407    o modfied mdsio_writefield.F to handle non-global files under exch2
1408    o update AIM Cubed-Sphere exp (aim.5l_cs):
1409      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1410    o update AIM Equatorial Channel exp:
1411      use standard aim_v23 pkg and change the SST fields to be more realistic.
1412    o globalFile now works with exch2
1413    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1414      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1415    o limit timeave output for hi-res integrations
1416    
1417    checkpoint52i_post
1418    o removed CPP_EEOPTIONS.h from verification/*/code
1419    o updated the tiling for global_ocean_pressure
1420    checkpoint52i_pre
1421    
1422    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1423      the old pkg/aim).
1424    
1425    checkpoint52h_pre
1426    o shortened offending lines in exch2_send_rx?.template
1427    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1428    o genmake2: add build & execute test for NetCDF code
1429    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1430      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1431    o added useSingleCPUIO flag to monitor.F and mon_out.F
1432    o added temporary hack for sea-ice dynamics on the cube:
1433      metric terms are ignored and it is assumed that
1434      there is no sea-ice on cube faces 1, 2, 4, and 5.
1435    
1436    checkpoint52f_post
1437    o added exch2 cube routines to pkg/exch2
1438    o modified hs94.cs-32x32x5 to use it
1439    o added new grid files to hs94.cs-32x32x5
1440    checkpoint52f_pre
1441    
1442    checkpoint52e_post
1443    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1444      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1445    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1446      to work with implicit vertical advection and AB ;
1447    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1448    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1449     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1450    checkpoint52e_pre
1451    
1452    o fix bug in impldiff when Nr=1 or Nr=2.
1453    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1454    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1455    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1456      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1457    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1458    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1459    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1460    
1461    checkpoint52d_post
1462    o re-tiled many expts to allow comparison in multi-processor mode
1463      - updated output accordingly
1464      - changed hs94.128x64x5 to use intial T from file rather than use the
1465        random number generator
1466    o add infrastructure in model routines for fizhi and gridalt packages
1467    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1468    o changes to permit hi-res, cubed-sphere, configuration

1470      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1471      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1472        of surface winds for the cube
1473      (A verification experiment, based on global_ocean.cs32x15, but with
1474       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1475       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1476       complete with example surface forcing files and matlab scripts to look
1477       at the output and compare it with that of global_ocean.cs32x15.)
1478    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1479       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1480       to conform to the common rule.
1481    o check-in the first version of the coupler + interfaces for multi-components
1482       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1483       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1484       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1485       - ocean and atmos. share the same horizontal grid (no interpolation).
1486       - exchanges between component and coupler is done in forward_step
1487    o new verification experiment, cpl_aim+ocn:
1488       coupled ocean - AIM atmosphere on cs32 grid.
1489    
1490    checkpoint52d_pre
1491    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1492    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1493    
1494    checkpoint52c_post
1495    o Fixing OPTIONS files for use of exf:
1496      - ALLOW_ECCO not needed
1497      - ECCO_CPPOPTIONS.h should not be included from
1498        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1499        as has been the case in the past
1500      - All cal/exf related options are currently set in
1501        single header file. Should remain so until we
1502        agree on a consistent new policy.
1503    o Removed all CPP options for cal package.
1504      cal has no more CPP options.
1505    o modified STOREs in GAD_ADVECTION
1506    o corrected key comp. for passkey
1507    
1508    checkpoint52b_post
1509    o new version: "thsice" of thermodynamic sea-ice pkg:
1510     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1511     - modify fluxes but do not change theta directly;
1512     - light cleaning of bulk_force pkg (still needed with thsice).
1513     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1514       + output_thsice.txt to test thsice & bulk_force pkgs.
1515    o put back grid & coriolis monitor output.
1516    checkpoint52b_pre
1517    
1518    o call "do_the_model_io" at the beginning (=> dump initial state)
1519    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1520    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1521      (need info on NUMBER_OF_PTRACERS)
1522    o missing PTRACERS headers in some routines
1523    o default tamc.h in pkg/autodiff supposed to crash
1524      to ensure proper customization
1525    
1526    checkpoint52a_post
1527    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1528      - moved surfaceTendencyTice from pkg/seaice to main code
1529      - subroutine FREEZE_SURFACE now limits only surface temperature
1530        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1531        => new output.txt for global_ocean.cs32x15 & global_with_exf
1532      - keep the old version of FREEZE for backward compatibility;
1533        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1534      - corresponding modifs for TAF directives
1535    o added surface flux output variables to TIMEAVE_STATVARS

1539      but no warning issued by TAF
1540    
1541    checkpoint52a_pre
1542    o some bug fixes for #undef REAL4_IS_SLOW
1543    
1544    checkpoint52 = ecco_c52_e35
1545    o after testing adjoints of checkpoint51u_post
1546    
1547    checkpoint51u_post
1548    o this is the post-merge tag of the ecco-branch
1549      (needs another clean checkout and re-testing)
1550    o various natl_box_adjoint configs and results
1551      but no input fields
1552    o obcs adjoint not yet merged!
1553    o adding ECCO global 1x1 and 2x2 degree configs
1554    o updated/extended some store directives for seaice
1555    o pkg/ecco now containes ecco-specific part of cost function
1556    o top level routines the_main_loop, forward_step
1557      supersede those in model/src/
1558      previous input data.cost now in data.ecco
1559      (new namelist ecco_cost_nml)
1560    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1561    
1562    checkpoint51t_post
1563    o this is the pre-merge tag of the ecco-branch
1564    
1565    checkpoint51s_post
1566    o cleanup: removed various obsolete #define-s
1567    o pkg/grdchk
1568      - renamed 'ph-grd 3' to 'grad-res'
1569      - merged from ecco-branch
1570        (remaining bug fixes for obcs gradient checks)
1571      - additional high-precision output for testreport
1572        (grep for 'precision_grdchk_result')
1573    
1574    checkpoint51r_post
1575    o cleaned up or removed CPP_OPTIONS.h files
1576    o updated results for some of the tests to reflect the new
1577      optfiles (-ieee: -O0 instead of -O3)
1578    
1579    checkpoint51q_post
1580    o cd_code:
1581      - moved cd_scheme.F -> cd_code_scheme.F
1582      - separate read_checkpoint from cd_code_ini_vars.F
1583      - separated cd_code part from write_checkpoint
1584      - updated AD_SOURCE, generated .flow
1585      - added CD_CODE_VARS.h to the_main_loop

1587    o ctrl package totally restructured
1588      - pack/unpack now optional and decoupled from
1589        xx_/adxx_ I/O
1590      - ctrl_pack/unpack cleaned
1591        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1592      - confined inclusion of AD_CONFIG.h to where necessary.
1593    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1594    
1595    checkpoint51p_post
1596    o create initial cd_code package
1597      - WARNING: the initialization of fields within packages
1598        is broken because INI_FIELDS (where READ_CHECKPOINT is
1599        called) is called *before* PACKAGES_INIT_VARIABLES.
1600        This seems to be backwards since
1601        1) its important to initially zero the entire field including
1602           the "halo" region
1603        2) zeroing needs to be done *before* reading pickup info
1604           and the pickup call might or might not happen in any
1605           particular run
1606      - this needs an overhaul for R2
1607    o cleanup verification/*/code/GMREDI_OPTIONS.h

1641      - moved surfaceTendencyTice from pkg/seaice to main code
1642      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1643      - subroutine FREEZE now limits only surface temperature
1644        (this means new output.txt for global_ocean.90x40x15,
1645         global_ocean.cs32x15, and global_with_exf)
1646    o added surface flux output variables to TIMEAVE_STATVARS

1816    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1817    o AIM: use true log-P extrapolation for near surface temp (= as in
1818        F.Molteni paper) ; update aim.5l_cs output.
1819    o New variable in PARM03 for more flexible pickups
1820    o somewhat cleaned package initialisation sequence for
1821      ctrl/ cost/ ecco/ in packages_... routines
1822    
1823    checkpoint50g_post

1851     - there is no analogue to SurfaceTendencyS, so I have to use
1852       gPtr(of the surface layer) instead
1853    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1854    checkpoint50e_pre

1876    
1877    checkpoint50b_post
1878    o store u*,v* in gU,V instead of in guNm1,gvNm1
1879    o in order to put the momForcing out of the Adams-Bashforth:
1880      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1881      to timestep.F
1882    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1883    o re-generate output for highly sensitive test-exp:
1884       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1885    
1886    checkpoint50b_pre
1887    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1888    o corrected CPP option mismatch in exf_Bulk... functions for case
1889      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1890    
1891    checkpoint50a_post
1892    o Bug fix for merging between c50 and KPP.
1893      ikey was passed from thermodynamics to kpp_calc via
1894      common block rather than being recomputed in kpp_calc,
1895      in contradiction with new key itdkey.
1896      New key ikppkey created, and tamc.h headers updated.
1897    
1898    checkpoint50
1899    - 2nd step of merge with ecco-branch:
1900      merge changes in ecco-branch back into main trunk
1901    - bug fix in find_alpha
1902    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1903    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1904    - merged some sliced AD support routines
1905    
1906    checkpoint49
1907    merged from ecco-branch:
1908    o exf:
1909      - Enable initialisation of forcing fields to constant
1910        (runtime) values.
1911      - in exf_getffields.F
1912        Reduce i-/j-loop to interior domain, discarding overlaps.
1913        That also fixes wrong TAF-key computations for key_1, key_2
1914        with bulf formulae.
1915      - exf_init.F modify #ifdef for exf_init_evap
1916      - exf_getffieldrec.F, ctrl_getrec.F
1917        The following INT-usages are not safe:
1918          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1919          fldcount = int(fldsecs/fldperiod) + 1
1920        and were modified.
1921    o autodiff: checkpoint_lev...
1922      - updated storing for bulk formulae (some arrays were missing)
1923      - added state for seaice package
1924      - synchronized with main branch
1925    o DIVA:
1926      Modif.s in
1927      - the_main_loop.F
1928      - the_model_main.F
1929      and added cost_final_restore.F cost_final_store.F
1930      o With these changes, it is possible to fully separate
1931        the first forward run to compute the cost function (mdthe_main_loop)
1932        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1933        into separate model executions.
1934        This enables better tuning of DIVA to given queue sizes.
1935      o Loss of cost function value in consecutive DIVA runs is
1936        fixed by storing to 'costfinal' file.
1937      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1938        beginning/end of adjoint integration is accounted for.
1939      The current changes apply to TAF-1.4.26.
1940      TAF has one remaining bug, requiring one manual change
1941      (see MITgcm manual).
1942    o cal: synchronized between MAIN and ecco-branch
1943    
1944    checkpoint48i_post
1945    o Changes to restore differentiability of code w.r.t. previous tag
1946      (mostly adding new routines to make list and replacing
1947      pressure by totPhiHyd).
1948    o Updated and merged grdchk package
1949      - has both ADM and TLM checks
1950      - works for single- and multi-proc.
1951      - output cleaned
1952      - worked successfully for parallel DIVA
1953    o genmake:
1954      - Adding -platform=SP4
1955      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1956    o Modif. for DIVA:
1957      ctrl_unpack should not be called in intermediate DIVA interval.
1958      (similar thing would apply for active files such as
1959      tbar, sbar, psbar, which should not be reinitialised;
1960      only relevant for ecco-branch)
1961    
1962    checkpoint48h_post
1963    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1964    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1965    o Added SEAICE_initialHEFF to pkg/seaice
1966    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1967    
1968    checkpoint48g_post
1969    --- EOS:
1970    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1971      store total Potential in totPhyHyd for diagnostics & EOS.
1972    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1973    --- Pressure/geopotential gradient:
1974    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1975    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1976      ( changes results of global_ocean_pressure )
1977    o NLFS + z-coord.: add eta*Rho' contribution.
1978    o accurate phiHyd when using interface-W at the middle between 2 centers
1979     ( changes results of ideal_2D_oce )
1980    o includes r* 2nd term in potential gradient.
1981    
1982    checkpoint48f_post
1983    Merging from release1_p12:
1984    o Modifications for using pkg/exf with pkg/seaice
1985      - improved description of the various forcing configurations

1987      - units/sign fix for evap computation in exf_getffields.F
1988      - updated verification/global_with_exf/results/output.txt
1989    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1990      (SBO) core products, including oceanic mass, center-of-mass,
1991      angular, and bottom pressure (see pkg/sbo/README.sbo).
1992    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1993      to avoid negative values in shallow regions.
1994      - updated verification/natl_box/results/output.txt
1995      - updated verification/lab_sea/results/output.txt
1996    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1997    o Added useSingleCpuIO option (see PARAMS.h).
1998    o Updated useSingleCpuIO option in mdsio_writefield.F to
1999      work with multi-field files, e.g., for single-file pickup.
2000    o pkg/seaice:
2001      - bug fix in growth.F: QNET for no shortwave case
2002      - added HeffFile for specifying initial sea-ice thickness
2003      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
2004    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
2005      kpp_transport_t.F, forward_step.F, and the_main_loop.F
2006    o pkg/seaice:
2007      - adjoint-friendly modifications
2008      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
2009    
2010    checkpoint48e_post
2011    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
2012    o dynamics: change definition of computational domain & adapt mom_fluxform
2013      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
2014    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
2015        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
2016        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
2017        global_ocean.90x40x15 global_with_exf global_ocean_pressure
2018        inverted_barometer solid-body.cs-32x32x1
2019      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
2020    
2021    checkpoint48d_post
2022    o in preparation for r*:
2023     a) use pre-computed gradient of hydrostatic potential:
2024        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
2025     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
2026        => affects results of glob_oce_pressure (different truncation error)  
2027      update output.txt of ideal_2D_oce & global_ocean_pressure
2028    
2029    checkpoint48d_pre
2030    o in preparation for r*:
2031      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
2032      pass the 2 comp. of the grad. as arguments to momentum S/R.
2033      but for the moment, only used if it does not change the results.
2034    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
2035    
2036    checkpoint48c_post
2037    Modifications in treatment of initial flux forcing controls
2038    to avoid extra storing of flux fields.
2039    
2040    checkpoint48c_pre
2041    o Added tidal_basin_2d experiment (currently 1D!)
2042    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
