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

609    
610    o pkg/diagnostics: prepare for Global/Regional statistics.
611      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
612    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
613      and rename it: DIFFERENT_MULTIPLE
614    
615    checkpoint57h_post
616    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
617    o pkg/diagnostics: change output frequency, now in seconds (instead
618      of Nb of iterations). This requires to change data.diagnostics.
619    checkpoint57h_pre
620    
621    o in mnc, let the user create the output dir if both mnc_outdir_date
622      and mnc_outdir_num are false
623    o add fflags() to pkg/diagnostics which allows one to specify, on a
624      per-file basis, the file precision [default behavior is unchanged]
625    o added diagnostics to pkg/kpp, including computation of mixed layer
626      depth based on a temperature/density criterion
627    o updated verification/natl_box to test the new pkg/kpp diagnostics
628    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
629    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
630    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
631      not mnc -- this mistake was found by JMC and is now corrected
632    
633    checkpoint57g_post
634    o add Adams-Bashforth 3rd Order time stepping:
635      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
636      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
637    checkpoint57g_pre
638    
639    o make lambda[Theta,Salt]ClimRelax spatially varying
640      (default remains spatially uniform constant based on tau)
641    o added new control variables
642      * init. uVel, vVel, etanN
643      * lambda[Theta,Salt]ClimRelax
644    o separate masks used for ctrl_pack/unpack 'from write_grid' output
645      (suggested by G. Forget)
646    
647    checkpoint57f_post

658    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
659      as well as grad(vort3).  Made it compatible with both approximate form
660      for the cubed sphere and full form of these gradients.  Added flag
661      useFullLeith to select between approximate and full form.  
662    o add "d0" in getcon.F to reduce differences between compilers/platforms
663      update output.txt of exp. fizhi-gridalt-hs
664    o change port_rand funtion to allow to set the seed.
665    o fix obscure MNC bug involving conversion between reals and integers
666      - it caused no problems with certain (eg. gcc, ifc) compilers but the
667        new version is now more standards-compliant
668    o adjoint-related modifications
669      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
670      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
671      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
672

678      update output.txt of exp. fizhi-gridalt-hs
679    o add more "Z" dimensions and associated coordinate vars to MNC
680    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
681    o parameter calendarDumps: when set, approximate months (30-31 days) and years
682      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
683      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
684      months and years.  Requires pkg/cal.
685    o diagnostics: add pickup functionality
686      - off by default for backwards compatibility
687      - current version only uses MDSIO -- MNC will be added
688    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
689    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
690    
691    checkpoint57d_post
692    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
693    o modify verification/ideal_2D_oce so that it tests the creation of mnc
694      output from the diagnostics package
695    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
696    o make genmake2 more portable by using ".$FS" instead of ".f" for more
697      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
698    o add coordinate variables to the MNC output from the diagnostics package
699    o change MNC-flags default value: true when useMNC=TRUE
700    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
701      the ability (off by default) to read the grid information using MNC
702    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
703    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
704    o do snap-shot diagnostics at the middle of the time-interval (instead of
705      at the end).
706    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
707      new test for AIM with thSIce + slab-ocean
708    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
709    o move state variable diagnostics to the beginning of the time step ;
710      (note: still needs some work specially for snap-shot diagnostics)
711      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
712    
713    checkpoint57c_post
714    o Change testing option (-ieee) to get closer agreement between g77 & ifort

719      update output.txt of exp. global_ocean.90x40x15
720    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
721      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
722    o add saltFlux(+File) forcing capability with periodicExternalForcing
723    o allow to use pkg diagnostics for GM-Redi & ThSIce output
724    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
725    o improvements for the MNC output from DIAGNOSTICS:
726      - correct handling of the unlimitied dimension
727      - all dims now have associated coordinate variables
728      - variables located at U, V, and Corner ("Z") points are now written
729        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
730        *all* data points are output
731    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
732    o added pkg/seaice/seaice_monitor.F
733    o mdsio_readfield.F can now read files visible only to master MPI process.
734    o pkg/seaice: some test code for ice-modified ocean stress
735    o exf_getffields interpolation defaults to bilinear for all scalar forcing
736      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
737      spurious negative numbers for precipitation and humidity.  Will cause
738      some small numerical differences for integrations using pkg/exf/exf_interp.F.
739    o pkg/ctrl/
740      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
741        May be enabled via doPackDiag
742      *  introduce z-scaling of
743         + gradient (doZscalePack) and
744         + control (doZscaleUnpack)
745    o pkg/mdsio/
746      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
747      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
748    
749    checkpoint57b_post
750    o simplify options in diagnostics_fill arguments (remove weird combinations)
751    o fix MNC coordinate variables so that they now contain per-face index
752      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
753      general, EXCH2 grids are only aligned to a "local" coordinate system
754    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
755    o Implement instantaneous output within pkg diagnostics:
756      setting a negative frequency in data.diagnostics produces
757     "snap-shot" output (as opposed to time-average if freq > 0)
758    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
759      NOTE: change ptracer diagnostics name: use 2 characters to work with
760            more than 9 tracers. Add also diagnostics of advect & diffus flux.
761    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
762      becomes the coordinate variable for the 'T' dimension
763    o add CF-style coordinate variables to MNC
764      - just a first cut:  numbers are meaningless on the cubesphere and
765        missing along the T axis but otherwise it works!
766    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
767    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
768    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
769      this is based directly on what the model compute, so that the content of
770      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
771    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
772    o clean up build options files for SunOS, in particular
773      - remove -traditional from xmakedepend
774      - change -xarch=v9 to -xarch=native for f77
775      - restore use of make (not gmake)
776      - add CC=gcc if using g77
777    o changes per discussion of AM, JMC, & EH3 today:
778      - move redundant "grid" variables out of "state" -- in preparation of
779        creating proper CF-style coordinate variables and in recognition
780        that any/all grid variables can be easily copied (eg. w/NCO) from
781        the grid files into any of the other NetCDF files
782      - *always* output grid variables with MDSIO (this will eventually be
783        changed)
784      - output MNC grid file if useMNC is true
785    o every instance of _END_MASTER() has been found and replaced with
786      _END_MASTER( myThid ) in order to satisfy certain picky Sun
787      preprocessors
788    o re-arrange diagnostics pkg initialisation:
789     - allow each package to extend the available diagnostics list
790     - add some checking and fix small problems (multi-threaded, ...)
791     - new S/R diagnostics_fill (replace fill_diagnostics):
792       look through the short list of active diag. (instead of the long list)
793       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
794    
795    checkpoint57a_post
796    o this set of changes restores TAMC compatibility
797      tested for global_ocean.90x40x15 adjoint on trough
798      (what a pain)
799    
800    checkpoint57a_pre
801    o some modifs in tools/build_options for sunos
802    o call ctrl_pack for ctrl at end for optimcycle=0
803    
804    checkpoint57
805    o add horizontal bi-harmonic viscosity for vertical velocity
806      - new parameter viscA4W (defaults to viscA4)
807      - affects only non-hydrostatic code
808      - to be done: no-slip lateral boundary conditions
809    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
810    o implement Implicit Vertical advection for pTracers
811    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
812      (implemented also for implicit vertical diffusion & advection)
813    o OBCS: extend application of tracer open boundary conditions
814      to a strip beyond the boundary of width Olx/Oly
815    o add call monitor to TAF set of required calls (flow directives)
816      and include in natl_box_adjoint
817    o untangle a few ifdefs related to cost, ctrl, autodiff
818      untangel a few ALLOW_ECCO_OPTIMIZATION
819    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
820      (theta2, salt2 in ecco_cost_weights)
821    
822    checkpoint56c_post
823    o OBCS as control variables
824      - update ctrl_ad_diff.list, obcs_ad_diff.list
825      - remove balance of obcs controls from default
826      - fix index bug nobcs in ctrl_init
827      - fix dummy fields filen in ctrl_pack
828      - add dummy weights for obcs
829    o lsopt: comment out fort.94 output
830    o optim:
831      - remove unnecessary header files
832      - adjusted namelists
833      - add xerbla.F to Makefile
834    o exf:
835      - multiple modifications of exf_check_range
836      - unit change in exf_init_runoff from [m/year] to [m/s]
837    o mdsio:
838      - i/o-vector change debugLevel from debLevA to debLevB
839    
840    checkpoint56b_post
841    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
842      is called from DO_THE_MODEL_IO
843      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
844      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
845      - clean up PTRACERS_WRITE_TIMEAVE a little
846    o add another verification experiment that tests both the cfc-pkg and
847      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
848      reactive tendencies treated inline with regular timestepping
849    o testreport previously did a lousy job of comparing small numbers, so
850      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
851      implemented in the little c-progam tmp_cmpnum.c which is embedded in
852      testreport.
853    o ptracers_monitor: bug fix for MPI
854    
855    checkpoint56a_post
856    o GCHEM: finish reorganizating the package
857      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
858        (introduces another 3D-array for each passive tracer, but only if
859        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
860        gchemTendency is not needed because the timestep is done separately)
861      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
862      - GCHEM is now---more or less cleanly---separate from PTRACERS
863      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
864        so clear to me how that should be done in a general way.
865    o CFC: improve formatting of output in CFC_ATMOS
866    o PTRACERS:
867      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
868        that ALL experiments with ptracers enable can be checked. This makes
869        GCHEM_MONITOR obsolete.
870      - include a runtime parameter PTRACERS_monitorFreq that defaults to
871        monitorFreq
872      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
873    o add PTRACERS (PTR0[1-5]) to testreport output
874    o exf_check_range:
875      * default changed to .TRUE.
876      * will check values for niter0 if debLevA, every timestep if debLevB
877      * STOP in exf_check_range if 'out of range'
878      * range chosen generous to allow for potential extema
879      TBD: a version with stricter range
880           permitted range would be runtime parameters
881    o GMredi:
882      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
883      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
884      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
885    o GCHEM:
886      - move call to GCHEM_FORCING_SEP, so that it is now called before
887        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
888      - introduced a useGCHEM runtime flag and applied it everywhere.
889      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
890        this flag is now only visible within GCHEM-pkg routines.
891      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
892        be replaced by a 3D array that is computed before thermodynamics; for
893        this, the tracer ID iTracer had to be included into the parameter list
894        of ptracers_forcing
895      - set up forward_step to call gchem_forcing, that will replace
896        gchem_forcing_int in ptracers_forcing
897      - cleaning up
898    o small cleaning of exch2: remove files that are also in eesupp/src
899    
900    checkpoint56
901    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
902    o mnc: cleanup "full" files--fixes out-of-memory problem
903    o ECCO-GODAE
904      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
905      * fully merged and updated from SIO code
906        windstress sign change affects
907        - exf_inscal_[u/v]stress
908        - sign of xx_tau[u/v] adjustments
909        - signs in cost_scat
910      * ctrl_get_gen: avoid update of tau[u/v] for first few days
911      * natl_box_adjoint updated and compressed
912      * 2-level checkpoint switch added
913        (tested in EXP. 1 of natl_box_adjoint)
914      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
915    o SVD
916      * first complete, non-hacked version for SVD calculations
917      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
918        performed via direct access files admtlm_vector.it????
919        (via ctrl_[un]pack)
920      * optimcycle is used for ARPACK iteration counter
921        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
922      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
923        and add linear transforms where necessary
924      * controls are initial/final SST, SSS (can be extended; need to check
925        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
926    o mdsio: filename info to both stderr, stdout
927    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
928      from sign change
929    
930    checkpoint55j_post
931    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
932      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
933    o add consistent build directories and .cvsignore files to verification
934    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
935    o make all subroutines 30 or less characters in length for certain older
936      compilers to work (a thorough search only turns up two routines in
937      pkg/ptracers)
938    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
939      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
940    
941    checkpoint55i_post
942    o change arrays for total vertical diffusivity (2.D if explicit,
943      3.D if implicit) ; each ptracer uses its own background value.
944    o added mnc/NetCDF output capability to ocn_compon_interf
945      - added bits to verification/cpl_aim+ocn so that it can run on
946        ITRDA and other clusters without the mpirun "-wd" option
947    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
948      configuration
949    o give MNC the ability to create additional files rather than
950      exceeding a specified file size limit "MNC_MAX_FILESIZE"
951      - the default is just less than 2GB which is a practical limit
952        on many systems
953    o Compute the non-local term using either KPP vertical diffusivity (=default)
954       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
955    
956    checkpoint55h_post
957    o add verification test "vermix"
958    o remove all the *_ioinc flags and replace with the single global
959      outputTypesInclusive flag
960    o allow to set a vertical profile of vertical diffusivity for T & S
961    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
962    o useMNC moved from data.mnc to data.pkg
963    
964    checkpoint55g_post
965    o Renaming carbon AD experiments to comply with testreport conventions
966    o Updating adjoint of Held-Suarez hs94.1x64x5
967    o Fixing directives for non-ECCO forward_step, after ECCO directives
968      have been fixed to avoid recomp. of do_oceanic_phys
969      Works well for global_ocean.90x40x15,
970      but recomp. issue remains for carbon
971    o Updating adjoint output for natl_box_adjoint after
972      pkg/ecco has been modified (see taga c55d_post)
973    
974    checkpoint55f_post
975    o rename to timeave_init_fixed
976    
977    checkpoint55e_post
978    o some delicate re-shuffle of store directives to avoid one
979      extra call of do_oceanic_physics
980      affects ecco_the_main_loop.F, do_oceanic_physics.F
981      checkpoint_lev1_directives.h
982    o NB: this may break global_ocean adjoint temporarily,
983      but it is clear how to fix it. Will do later, need this now.
984    
985    checkpoint55d_post
986    o ECCO specific cost function terms (up-to-date with 1x1 runs)
987    o ecco_cost_weights is modified to 1x1 runs
988    o modifs to allow observations to be read in as
989      single file or yearly files
990    o enable to read exf forcing fields as either
991      single file or yearly files (flag useExfYearlyFields)
992    checkpoint55d_pre
993    
994    o switch between 2-level and 3-level checkpointing
995    o add ability of MNC to write local and "partial" (eg. 2D slices where
996      the full 3D field is never actually stored) arrays to NetCDF files
997      with the correct (that is, the complete multi-dimensional) set of
998      array indicies
999      - used in mom_vecinv() to write the diagFreq output
1000      - tested (demonstrated) in verification/aim.5l_cs
1001    o further mnc-ification
1002      - add verification/lab_sea to the list with mnc setups
1003      - fix undefined mnc v-names in cd_code
1004      - add kpp to mnc output (both snapshot and timeave)
1005    o non-hydrostatic code
1006      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1007        in calc_gw.F
1008      - defaults to viscAh
1009      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1010        friction or Leith) in non-hydrostatic mode, as long as there is
1011        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1012    o pkg/cost
1013      extend simple cost functions to treat time mean quantities
1014      (T,U,V) via cost_accumulate_state from cost_tile
1015    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1016        be 2 times larger than the minimum size the advection scheme requires.
1017        now get a perfect conservation of salt in advect_cs test-exp (updated)
1018    o GGL90 (Gaspar's TKE mixed layer)
1019      - add horizontal diffusion of TKE, requires exchanges in
1020        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1021        default. In OPA there is no horizontal diffusion of TKE but the
1022        mixing coefficients are computed from a horizontal average of TKE of
1023        6 points or so. I think that diffusion has a little more physical
1024        justification.
1025      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1026        was in vain)
1027      - mask tke-variable in ggl90_init
1028    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1029    o fix biharmonic diffusion on CS-grid.
1030    o more obcs stuff
1031      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1032        for reading boundary values. This routine is called from
1033        obcs_prescribe_read
1034      - updated obcs_check
1035      - changed sponge layer relaxation parameter units for days to seconds
1036      - turned off sponge layer by default
1037      - changed argument list of OBCS_CALC to myTime+deltaTclock
1038      - fixed about 35 bugs in obcs_external_fields_load
1039    
1040    checkpoint55c_post
1041    o obcs stuff
1042      - new runtime flags useOBCSprescribe, useOBCSbalance
1043      - re-arranged obcs_calc
1044      - moved exf_getobcs to obcs_prescibe_read
1045        obcs_prescibe_read is called after ORLANSKI stuff
1046        and independent of it (executable can contain all).
1047      - updated obcs_check
1048      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1049        These may be necessary only if tangential velocities are
1050        prescribed at OB, not sure, needs testing.
1051    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1052      which simplifies the calls and passes the ifc check-bounds test
1053    
1054    checkpoint55b_post
1055    o add a 2D scalar, Z location, exchange_2 routine.
1056    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1057      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1058      affects advect_cs results (for the wrong reason): update output.txt
1059    o use a more standard discretization for biharmonic viscosity ;
1060     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1061      affects results of dome set-up: update output.txt
1062    o fix gad_advection.F (CubedSphere part), back to version 1.23
1063    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1064    
1065    checkpoint55a_post
1066    o merged code to
1067      * prescribe/read time-dependent open boundaries
1068        (works in conjunction with exf, cal)
1069      * sponge layer code for open boundaries
1070      * each boundary N/S/E/W now has its own CPP option
1071        (healthy for the adjoint)
1072    
1073    checkpoint55
1074    o up-to-date adjoint of previous breaks
1075      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1076      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1077      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1078      - carbon: * remove tr1-related adjoint verification
1079                * add ptracer as control variable
1080    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1081      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1082    
1083    checkpoint54f_post
1084    o in verification/carbin/ remove experiment related to
1085      ALLOW_PASSIVE_TRACER (array tr1 etc)
1086      code_ad/ input_ad/ results_ad
1087    
1088    o add two new packages
1089      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1090        + subject to optimization (memory)
1091      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1092        + subject to reordering (many GOTOs in the original code)
1093        + so far opps is called for every (i,j) point, and then operates in
1094          the vertical; one may want to reorder the scheme in order operate in
1095          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1096          fields)
1097    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1098      - all verification tests compile and run with linux_ia32_g77
1099      - defaults are compatible with current input files--nothing
1100        should change if you were not previously using MNC
1101      - MNC output has been added in numerous places (eg. timeave)
1102        but there are still a few writes not yet do-able with MNC
1103        (this is in progress)
1104      - flags now allow for either/or/both use of MDSIO and MNC and
1105        documentation will soon follow
1106      - numerous small formatting cleanups for ProTeX
1107    o add version info (via BUILD_INFO.h) to MNC and stdout
1108    
1109    checkpoint54e_post
1110    o add two new packages
1111      - pp81 (Packanowski and Philander, 1981), Richardson number and
1112        stratification dependent mixing
1113      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1114      - these scheme operate in a similar manner as KPP (without ghat, of
1115        course), however there is only one diffusivity that is used for both
1116        temperature and salinity (and passive tracers)ç
1117    o add offline package
1118    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1119      provided by Stephanie Dutkiewicz
1120    o genmake2: add ability to search for C compilers and cleanup test output
1121      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1122    
1123    checkpoint54d_post
1124    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1125    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1126      leading to additional shift by 5 days each year of integration
1127       (i.e. leading to considerable offset over the years)
1128    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1129    o start with no AB and no initial filtering (staggerTimeStep):
1130      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1131    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1132      (external loading & cpl import/export stay in forward_step.F)
1133    o update coupling interface to work with new staggerTimeStep
1134    o change MDSIO ptracers_pickup.
1135    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1136    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1137    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1138    
1139    checkpoint54c_post
1140    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1141      this affects (truncation error) output.txt of test-exp:
1142       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1143    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1144    o change Qnet to always be the net heat flux, (+upward).
1145      affects (truncation error) output of natl_box exp.: updated
1146    o define the max number of passive tracers in PTRACERS_SIZE.h
1147    o start to test mnc routinely in exp0
1148    o add sea-ice loading (sIceLoad) as a new forcing field.
1149    
1150    checkpoint54b_post
1151    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1152       impressive on Altix and Opteron systems)
1153    o diagnostics can now write NetCDF files through the mnc package
1154    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1155    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1156    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1157      affects (truncation error) output of lab_sea & natl_box exp.: updated
1158    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1159    
1160    checkpoint54a_post
1161    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1162    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1163    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1164    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1165      + internal_wave (shift in writing cg2d_ini_res)
1166    checkpoint54a_pre
1167    
1168    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1169      - modified verification/lab_sea and natl_box_adjoint accordingly
1170    
1171    checkpoint54
1172    checkpoint53g_post
1173    o prepare splitting of thermodynamics: store convect.counter in common block
1174    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1175      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1176    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1177    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1178    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1179    o restore adjointability
1180    
1181    checkpoint53f_post
1182    o modifications that affect AIM experiment results (update output.txt):
1183      - no advection of S at top interface Nr (pkg/generic_advdiff)
1184      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1185    o AIM pkg:
1186      - include stability function into surf.Flux derivative relative to Tsurf
1187      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1188    
1189    checkpoint53e_post
1190    o merged cylindrical coord configuration
1191    o added rotating_tank experiment
1192    checkpoint53e_pre
1193    
1194    checkpoint53d_post
1195    o faulks upgraded: re-generate output.txt that have changed:
1196       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1197    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1198    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1199    o added Sadourny discretization of Coriolis
1200      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1201      - re-enabled use of omega3 (useAbsVorticity)
1202    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1203      vector-invariant equations
1204      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1205    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1206      hopefully without new bugs
1207      - still to do: biharmonic friction for non-hydrostatic w
1208    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1209    o regenerated output for global_ocean_ebm (using -ieee)
1210    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1211      of mom_common/
1212      - simple re-arrangement of instructions within computing loop
1213    checkpoint53d_pre
1214    
1215    checkpoint53c_post
1216    o new version of coupler for AIM+thSIce and Ocean models
1217     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1218     - land: change Evaporation of snow
1219     - aim with thSIce: fix bug in snow-precip.
1220    o changes to calc_gw.F
1221     - bug fix for w^2 term near the bottom boundary
1222     - (hopefully) improve the lateral slip boundary condtions for use with
1223        partial/looped cells
1224      - because the bug fix changes two verification experiments anyway (exp5
1225        and plume on slope), change the lateral boundary condition from half slip
1226        to the value of no_slip_sides
1227    o ebm package wasnt quite up to the parallel task. Fixed that.
1228    o Adjoint of EBM package + verification
1229      * TLM OK
1230      * ADM not sufficient accuracy yet (needs further testing)
1231    
1232    checkpoint53b_post
1233    o Commiting new energy balance model to repository
1234      * package is pkg/ebm
1235      * verif. is verification/global_ocean_ebm
1236      * references are in ebm_driver.F
1237    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1238    C        Global thermohaline circulation. Part I:
1239    C        Sensitivity to atmospheric moisture transport.
1240    C        J. Climate 12(1), 71-82
1241    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1242    C        Global thermohaline circulation. Part II:
1243    C        Sensitivity with interactive transport.
1244    C        J. Climate 12(1), 83-91
1245    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1246    C        Destabilization of the thermohaline circulation
1247    C        by atmospheric eddy transports.
1248    C        J. Climate 7(12), 1870-1882
1249    o Will need long integration testing.
1250    checkpoint53b_pre
1251    
1252    o created pkg/mom_common in preparation for variable viscosity code
1253    o renamed and split ini_mnc_io
1254    o pkg/land: only liquid water can diffuse or run-off
1255    o AIM using land: soil wetness availability account for snow
1256    o added printMapIncludesZeros to EEPARMS namelist
1257    
1258    checkpoint53a_post
1259    o restore TAMC compatiility for exf_constants.h
1260      (no usage of _d in .h)
1261    o Additional storing in KPP in an attempt to fix
1262      TAMC problem with adjoint of KPP code.
1263      (no success...)
1264      Identical code works fine with TAF.
1265    o Fixed verification/natl_box_adjoint experiments.
1266      Initial conditions for Experiments 4 and 5 are now
1267      set to "SEAICE_initialHEFF=0", which is more reasonable,
1268      and hence gives results closer to that of Experiment 2.
1269      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1270    
1271    checkpoint53
1272    o stable checkpoint with up to date adjoint
1273      TLM tests only run for 1st grdchk at the moment. Its unclear if
1274      this is a code problem or a problem with resetting code for g_
1275      variables that is being autogenerated wrong.
1276      Otherwise:
1277       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1278       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1279         are both still in chaos following their security messes.
1280    
1281    checkpoint52n_post
1282    o various build (mostly genmake2) changes including:
1283      - ability to build/run more easily within Cygwin and MacOS X
1284      - more complicated Makefiles with a stronger dependence on Gnu Make
1285    o pkg/seaice modifications
1286      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1287        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1288        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1289      - changed proxy for geostrophic velocity and updated
1290        verification/lab_sea/results/* accordingly
1291      - removed ADI dynamic solver from pkg/seaice
1292      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1293        they caused a segmentation fault under certain circumstances
1294      - removed unused field WATR
1295    o bug fix in exf-package:
1296      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1297         now reflect that.
1298    o small fixes in the cal-package:
1299      - set reference date to first of January for the 'model'-calendar
1300      - failing of cal_CheckDate in cal_FullDate now actually results in a
1301        warning
1302    o small modifications in exf-package to increase flexibility:
1303      - change climtempfreeze from a constant to a runtime parameter that
1304        is specified in data.exf_clim (default = -1.9)
1305      - introduce runtime parameter windstressmax (default = 2.0) that is
1306        specified in data.exf
1307    o fix in pkg/thsice:
1308      - update Evap (Tsf changes) to be consistent with Latent heat flux
1309      - maintain snow precipitation unchanged (even if Tsf >=0).
1310     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1311    
1312    checkpoint52m_post
1313    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1314      this does not change any of the results, because myIter=0 in swfrac always
1315      lead to jwtype=2 (the default anyway), but the call makes little sense
1316      as a default
1317    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1318    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1319      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1320    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1321    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1322    o extending useSingleCpuIO option to work with new exch2 I/O format
1323      - old-style, missing-tile I/O is still accessible by defining CPP
1324        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1325    o monitor package can write to NetCDF files and/or STDOUT
1326    o fix re-definition bug in MNC_GRID_INIT_ALL()
1327    o doc/api_reference added
1328      - a framework for building an API Reference Manual using all
1329        the "protex" comments embedded in the code
1330      - see pkg/generic_advdiff, pkg/mnc for examples
1331    o MNC:
1332      - make myThid the last argument for all subroutines
1333      - new default for the grid files: NO halos
1334      - add useMNC and other run-time flags
1335      - separate per-file-group handling of the unlimited dimension
1336      - early initialization of MNC w/ flags read at the eeboot stage
1337        and lookup tables set in initialize_fixed
1338      - write all MNC output to a freshly-created directory
1339    o thermodynamics sea-ice (thsice) is now tested with testreport.
1340    o test exp. advect_cs: use the standard cs32 grid ; update output.
1341    o Added functionality to grdchk:
1342      pick global i,j,k position (or nearest wet) where to perform check.
1343    
1344    checkpoint52l_post
1345    o new land formulation:
1346      a) use ground enthalpy as prognostic variable to ensure exact
1347         energy conservation.
1348      b) account for water temperature and for latent heat of freezing
1349         in all processes (rain, run-off, ground storage)
1350      c) compute surface and ground temperature implicitly.
1351    o aim_v23 modification for new land model:
1352      a) Treat separately land / ocean / sea-ice surface fluxes
1353         to allow implicit computation of land & sea-ice surface temp.
1354      b) add snow precipitation.
1355    checkpoint52l_pre
1356    
1357    o fix problem (when 1 tile is empty) in min/max monitor.
1358    o fix bug in timeAve (u,vZetatave in common block)
1359    o no restoring terms under ice for pkg/seaice
1360    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1361    o bug fix for pkg/seaice pickups
1362    o change MNC call locations and add coordinate attributes
1363    o mask vorticity at the corner ; affects global_ocean.cs output
1364    o fix ini_curvilinear_grid ; test CS experiments with mpi
1365    o aim.5l_cs: modify sea-ice fraction input file ; update output
1366    o exf: Adding simple range check routine for exf fields after read
1367    
1368    checkpoint52k_post
1369    o removed top-level directory "diags"
1370      - we migrated these functions to pkg/timeave a long time ago
1371    o fixed bug introduced in pkg/monitor
1372    o accuracy ctrlprec = 32 insuffient for gradient checks using
1373      averaged fields (I/O via cost_averages)
1374      -> use ctrl.h in active_file*.F to control I/O precision.
1375    o paramter list of CALL ADTHE_MAIN_LOOP
1376    o added initial do_the_model_io to ecco
1377    o set all ...Freq to zero after cost_final
1378      taveFreq, dumpFreq, pChkptFreq
1379    o MAIN and ECCO differentiability restored
1380    
1381    checkpoint52j_post
1382    o fix nchklev in tamc.h for global_ocean...
1383    o Bringing flow and store directives up-to-date
1384    o Really weird thing!
1385      call do_the_model_io from the_main_loop with parameters
1386      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1387      TAF places a faulty re-call of initialise_varia
1388      after cost_final call which should not be there!
1389    checkpoint52j_pre
1390    
1391    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1392      error messages
1393    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1394    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1395      debug output
1396    o modfied mdsio_writefield.F to handle non-global files under exch2
1397    o update AIM Cubed-Sphere exp (aim.5l_cs):
1398      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1399    o update AIM Equatorial Channel exp:
1400      use standard aim_v23 pkg and change the SST fields to be more realistic.
1401    o globalFile now works with exch2
1402    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1403      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1404    o limit timeave output for hi-res integrations
1405    
1406    checkpoint52i_post
1407    o removed CPP_EEOPTIONS.h from verification/*/code
1408    o updated the tiling for global_ocean_pressure
1409    checkpoint52i_pre
1410    
1411    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1412      the old pkg/aim).
1413    
1414    checkpoint52h_pre
1415    o shortened offending lines in exch2_send_rx?.template
1416    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1417    o genmake2: add build & execute test for NetCDF code
1418    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1419      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1420    o added useSingleCPUIO flag to monitor.F and mon_out.F
1421    o added temporary hack for sea-ice dynamics on the cube:
1422      metric terms are ignored and it is assumed that
1423      there is no sea-ice on cube faces 1, 2, 4, and 5.
1424    
1425    checkpoint52f_post
1426    o added exch2 cube routines to pkg/exch2
1427    o modified hs94.cs-32x32x5 to use it
1428    o added new grid files to hs94.cs-32x32x5
1429    checkpoint52f_pre
1430    
1431    checkpoint52e_post
1432    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1433      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1434    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1435      to work with implicit vertical advection and AB ;
1436    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1437    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1438     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1439    checkpoint52e_pre
1440    
1441    o fix bug in impldiff when Nr=1 or Nr=2.
1442    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1443    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1444    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1445      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1446    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1447    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1448    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1449    
1450    checkpoint52d_post
1451    o re-tiled many expts to allow comparison in multi-processor mode
1452      - updated output accordingly
1453      - changed hs94.128x64x5 to use intial T from file rather than use the
1454        random number generator
1455    o add infrastructure in model routines for fizhi and gridalt packages
1456    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1457    o changes to permit hi-res, cubed-sphere, configuration
1458      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1459      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1460      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1461        of surface winds for the cube
1462      (A verification experiment, based on global_ocean.cs32x15, but with
1463       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1464       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1465       complete with example surface forcing files and matlab scripts to look
1466       at the output and compare it with that of global_ocean.cs32x15.)
1467    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1468       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1469       to conform to the common rule.
1470    o check-in the first version of the coupler + interfaces for multi-components
1471       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1472       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1473       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1474       - ocean and atmos. share the same horizontal grid (no interpolation).
1475       - exchanges between component and coupler is done in forward_step
1476    o new verification experiment, cpl_aim+ocn:
1477       coupled ocean - AIM atmosphere on cs32 grid.
1478    
1479    checkpoint52d_pre
1480    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1481    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1482    
1483    checkpoint52c_post
1484    o Fixing OPTIONS files for use of exf:
1485      - ALLOW_ECCO not needed
1486      - ECCO_CPPOPTIONS.h should not be included from
1487        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1488        as has been the case in the past
1489      - All cal/exf related options are currently set in
1490        single header file. Should remain so until we
1491        agree on a consistent new policy.
1492    o Removed all CPP options for cal package.
1493      cal has no more CPP options.
1494    o modified STOREs in GAD_ADVECTION
1495    o corrected key comp. for passkey
1496    
1497    checkpoint52b_post
1498    o new version: "thsice" of thermodynamic sea-ice pkg:
1499     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1500     - modify fluxes but do not change theta directly;
1501     - light cleaning of bulk_force pkg (still needed with thsice).
1502     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1503       + output_thsice.txt to test thsice & bulk_force pkgs.
1504    o put back grid & coriolis monitor output.
1505    checkpoint52b_pre
1506

1508    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1509    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1510      (need info on NUMBER_OF_PTRACERS)
1511    o missing PTRACERS headers in some routines
1512    o default tamc.h in pkg/autodiff supposed to crash
1513      to ensure proper customization
1514    
1515    checkpoint52a_post
1516    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1517      - moved surfaceTendencyTice from pkg/seaice to main code
1518      - subroutine FREEZE_SURFACE now limits only surface temperature
1519        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1520        => new output.txt for global_ocean.cs32x15 & global_with_exf
1521      - keep the old version of FREEZE for backward compatibility;
1522        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1523      - corresponding modifs for TAF directives
1524    o added surface flux output variables to TIMEAVE_STATVARS

1531    o some bug fixes for #undef REAL4_IS_SLOW
1532    
1533    checkpoint52 = ecco_c52_e35
1534    o after testing adjoints of checkpoint51u_post
1535    
1536    checkpoint51u_post
1537    o this is the post-merge tag of the ecco-branch
1538      (needs another clean checkout and re-testing)
1539    o various natl_box_adjoint configs and results
1540      but no input fields
1541    o obcs adjoint not yet merged!
1542    o adding ECCO global 1x1 and 2x2 degree configs
1543    o updated/extended some store directives for seaice
1544    o pkg/ecco now containes ecco-specific part of cost function
1545    o top level routines the_main_loop, forward_step
1546      supersede those in model/src/
1547      previous input data.cost now in data.ecco
1548      (new namelist ecco_cost_nml)
1549    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1550    
1551    checkpoint51t_post
1552    o this is the pre-merge tag of the ecco-branch
1553    
1554    checkpoint51s_post
1555    o cleanup: removed various obsolete #define-s
1556    o pkg/grdchk
1557      - renamed 'ph-grd 3' to 'grad-res'
1558      - merged from ecco-branch
1559        (remaining bug fixes for obcs gradient checks)
1560      - additional high-precision output for testreport
1561        (grep for 'precision_grdchk_result')
1562    
1563    checkpoint51r_post
1564    o cleaned up or removed CPP_OPTIONS.h files
1565    o updated results for some of the tests to reflect the new
1566      optfiles (-ieee: -O0 instead of -O3)
1567    
1568    checkpoint51q_post
1569    o cd_code:
1570      - moved cd_scheme.F -> cd_code_scheme.F
1571      - separate read_checkpoint from cd_code_ini_vars.F
1572      - separated cd_code part from write_checkpoint
1573      - updated AD_SOURCE, generated .flow
1574      - added CD_CODE_VARS.h to the_main_loop

1577      - pack/unpack now optional and decoupled from
1578        xx_/adxx_ I/O
1579      - ctrl_pack/unpack cleaned
1580        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1581      - confined inclusion of AD_CONFIG.h to where necessary.
1582    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1583    
1584    checkpoint51p_post
1585    o create initial cd_code package
1586      - WARNING: the initialization of fields within packages
1587        is broken because INI_FIELDS (where READ_CHECKPOINT is
1588        called) is called *before* PACKAGES_INIT_VARIABLES.
1589        This seems to be backwards since
1590        1) its important to initially zero the entire field including
1591           the "halo" region
1592        2) zeroing needs to be done *before* reading pickup info
1593           and the pickup call might or might not happen in any
1594           particular run
1595      - this needs an overhaul for R2
1596    o cleanup verification/*/code/GMREDI_OPTIONS.h

1630      - moved surfaceTendencyTice from pkg/seaice to main code
1631      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1632      - subroutine FREEZE now limits only surface temperature
1633        (this means new output.txt for global_ocean.90x40x15,
1634         global_ocean.cs32x15, and global_with_exf)
1635    o added surface flux output variables to TIMEAVE_STATVARS

1876    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1877    o corrected CPP option mismatch in exf_Bulk... functions for case
1878      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1879    
1880    checkpoint50a_post
1881    o Bug fix for merging between c50 and KPP.
1882      ikey was passed from thermodynamics to kpp_calc via
1883      common block rather than being recomputed in kpp_calc,
1884      in contradiction with new key itdkey.
1885      New key ikppkey created, and tamc.h headers updated.
1886    
1887    checkpoint50
1888    - 2nd step of merge with ecco-branch:
1889      merge changes in ecco-branch back into main trunk
1890    - bug fix in find_alpha
1891    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1892    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1893    - merged some sliced AD support routines
1894    
1895    checkpoint49
1896    merged from ecco-branch:
1897    o exf:
1898      - Enable initialisation of forcing fields to constant
1899        (runtime) values.
1900      - in exf_getffields.F
1901        Reduce i-/j-loop to interior domain, discarding overlaps.
1902        That also fixes wrong TAF-key computations for key_1, key_2
1903        with bulf formulae.
1904      - exf_init.F modify #ifdef for exf_init_evap
1905      - exf_getffieldrec.F, ctrl_getrec.F
1906        The following INT-usages are not safe:
1907          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1908          fldcount = int(fldsecs/fldperiod) + 1
1909        and were modified.
1910    o autodiff: checkpoint_lev...
1911      - updated storing for bulk formulae (some arrays were missing)
1912      - added state for seaice package
1913      - synchronized with main branch
1914    o DIVA:
1915      Modif.s in
1916      - the_main_loop.F
1917      - the_model_main.F
1918      and added cost_final_restore.F cost_final_store.F
1919      o With these changes, it is possible to fully separate
1920        the first forward run to compute the cost function (mdthe_main_loop)
1921        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1922        into separate model executions.
1923        This enables better tuning of DIVA to given queue sizes.
1924      o Loss of cost function value in consecutive DIVA runs is
1925        fixed by storing to 'costfinal' file.
1926      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1927        beginning/end of adjoint integration is accounted for.
1928      The current changes apply to TAF-1.4.26.
1929      TAF has one remaining bug, requiring one manual change
1930      (see MITgcm manual).
1931    o cal: synchronized between MAIN and ecco-branch
1932    
1933    checkpoint48i_post
1934    o Changes to restore differentiability of code w.r.t. previous tag
1935      (mostly adding new routines to make list and replacing
1936      pressure by totPhiHyd).
1937    o Updated and merged grdchk package
1938      - has both ADM and TLM checks
1939      - works for single- and multi-proc.
1940      - output cleaned
1941      - worked successfully for parallel DIVA
1942    o genmake:
1943      - Adding -platform=SP4
1944      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1945    o Modif. for DIVA:
1946      ctrl_unpack should not be called in intermediate DIVA interval.
1947      (similar thing would apply for active files such as
1948      tbar, sbar, psbar, which should not be reinitialised;
1949      only relevant for ecco-branch)
1950    
1951    checkpoint48h_post
1952    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1953    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1954    o Added SEAICE_initialHEFF to pkg/seaice
1955    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1956    
1957    checkpoint48g_post
1958    --- EOS:
1959    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1960      store total Potential in totPhyHyd for diagnostics & EOS.
1961    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1962    --- Pressure/geopotential gradient:
1963    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1964    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1965      ( changes results of global_ocean_pressure )
1966    o NLFS + z-coord.: add eta*Rho' contribution.
1967    o accurate phiHyd when using interface-W at the middle between 2 centers
1968     ( changes results of ideal_2D_oce )
1969    o includes r* 2nd term in potential gradient.
1970    
1971    checkpoint48f_post
1972    Merging from release1_p12:
1973    o Modifications for using pkg/exf with pkg/seaice
1974      - improved description of the various forcing configurations
1975      - added basic radiation bulk formulae to pkg/exf
1976      - units/sign fix for evap computation in exf_getffields.F
1977      - updated verification/global_with_exf/results/output.txt
1978    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1979      (SBO) core products, including oceanic mass, center-of-mass,
1980      angular, and bottom pressure (see pkg/sbo/README.sbo).
1981    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1982      to avoid negative values in shallow regions.
1983      - updated verification/natl_box/results/output.txt
1984      - updated verification/lab_sea/results/output.txt
1985    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1986    o Added useSingleCpuIO option (see PARAMS.h).
1987    o Updated useSingleCpuIO option in mdsio_writefield.F to
1988      work with multi-field files, e.g., for single-file pickup.
1989    o pkg/seaice:
1990      - bug fix in growth.F: QNET for no shortwave case
1991      - added HeffFile for specifying initial sea-ice thickness
1992      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1993    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1994      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1995    o pkg/seaice:
1996      - adjoint-friendly modifications
1997      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1998    
1999    checkpoint48e_post
2000    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
2001    o dynamics: change definition of computational domain & adapt mom_fluxform
2002      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
2003    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
2004        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
2005        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
2006        global_ocean.90x40x15 global_with_exf global_ocean_pressure
2007        inverted_barometer solid-body.cs-32x32x1
2008      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
2009    
2010    checkpoint48d_post
2011    o in preparation for r*:
2012     a) use pre-computed gradient of hydrostatic potential:
2013        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
2014     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
2015        => affects results of glob_oce_pressure (different truncation error)  
2016      update output.txt of ideal_2D_oce & global_ocean_pressure
2017    
2018    checkpoint48d_pre
2019    o in preparation for r*:
2020      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
2021      pass the 2 comp. of the grad. as arguments to momentum S/R.
2022      but for the moment, only used if it does not change the results.
2023    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
2024    
2025    checkpoint48c_post
2026    Modifications in treatment of initial flux forcing controls
2027    to avoid extra storing of flux fields.
2028    
2029    checkpoint48c_pre
2030    o Added tidal_basin_2d experiment (currently 1D!)
2031    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
2032    
2033    checkpoint48b_post
2034    o r* coordinate added in #ifdef NONLIN_FRSURF block.
2035     (modification to pressure gradient not yet implemented)
2036    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
2037      (for U & V) that are used for vertical advection of momentum.
2038    
2039    checkpoint48a_post
2040    o In preparation for r*, use temp. array to compute vertical transport
2041       in flux-form momentum pkg. => change results of few test-exp.
2042      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
2043                        lab_sea, natl_box & plume_on_slope
2044    
2045    checkpoint48
2046    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
2047    
2048    checkpoint47j_post
2049    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
2050    o moved adexch from forward_step to addummy_in_stepping
2051    o added exch in ctrl_map_...
2052    o aveFreq.=0. at end of cost_final to avoid overwrite in
2053      reverse checkpointing loop
2054    o Yet more changes in gmredi:
2055      * adgmredi_calc_tensor
2056        avoiding all recomputation of gmredi_slope_limit
2057      * adgmredi_x/y/rtransport
2058        added flag for excessive storing to avoid recomp. of
2059        u/v/rtans, dTdx/y/z
2060        -> this is not really necessary and very memory-consuming
2061      * adgmredi_slope_psi:
2062        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
2063      * gmredi_slope_limit
2064        re-activated full calculation of taperfct for case 'ac02'
2065    o updating verification/ adjoints of carbon, global_ocean.90x40x15
2066    
2067    checkpoint47i_post
2068    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
2069    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
2070      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
2071    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
2072    o gmredi: fix few bugs.
2073    
2074    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
2075    This will be a good checkpoint to plug into the ecco-branch.
2076    o few modif.'s to get latest version adjointed
2077      (mainly kick out code in ini_linear_phisurf)
2078    o modif's to run adjoint with exactConserv
2079    o case GM_BOLUS_ADVEC should be cleaned
2080      S/R gmredi_slope_psi should be cleaned
2081    o verification/carbon now has exactConserv=.TRUE.
2082    
2083    checkpoint47g_post
2084    o time-average AIM output: becomes independent from statvars time-average
2085      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
2086    o After TAF bug fix:
2087      Tested adjoint of gmredi package.
2088      Tests were done with checkpoint47 rather than with latest
2089      checkpoint47f_post since the latter is broken for the adjoint
2090      verification/carbon/ contains both ADM and TLM gradient checks.
2091    Here they are, before they get changed/lost/stolen.
2092    Mostly modif.'s to fix numerical sensitivities.
2093    Gradient checks OK for
2094    - GM_taper_scheme:
2095      * clipping
2096      * ac02
2097      * linear
2098      * glw91
2099      * dm95
2100      * ldd97
2101    - GMREDI_OPTIONS:
2102      * GM_VISBECK_VARIABLE_K
2103      * GM_NON_UNITY_DIAGONAL
2104      * GM_EXTRA_DIAGONAL
2105      * GM_BOLUS_ADVEC
2106    in conjunction with data.gmredi parameters to be checked in
2107    in a few minutes under verification/carbon/code/
2108    
2109    checkpoint47f_post
2110    Merging from release1_p10:
2111    o modifications for using pkg/exf with pkg/seaice
2112      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
2113        and SEAICE_EXTERNAL_FLUXES
2114      - pkg/exf CPP options EXF_READ_EVAP and
2115        EXF_NO_BULK_COMPUTATIONS
2116      - usage examples are Experiments 8 and 9 in
2117        verification/lab_sea/README
2118      - verification/lab_sea default experiment now uses
2119        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
2120    
2121    checkpoint47e_post
2122    o created a tag prior to creating a branch
2123    
2124    checkpoint47d_post
2125    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
2126      at the bottom boundary had an erroneous half slip boundary condition
2127    o added bottom drag and no slip boundary condition capabilities to
2128      oceanic pressure coordinates code
2129    o added new verification experiment global_ocean_pressure, this experiment is
2130      also described in the tutorial section of the manual
2131    checkpoint47d_pre
2132    
2133    checkpoint47c_post
2134    o Added a verification experiment for a global cubed-sphere ocean run
2135      -  verification/global_ocean.cubed32x32x30
2136      -  uses pkg/therm_seaice and pkg/bulk_forcing
2137    
2138    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
2139    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
2140      when using P-coordinate; only implemented for atmospheric config.
2141    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
2142      NOTES: requires option NONLIN_FRSURF to be "#define".
2143    o update advect_xz/results/output.txt (left from checkpoint44g_post)
2144    
2145    checkpoint47b_post
2146    Merging from release1_p9:
2147    o pkg/seaice
2148      - removed GOTO's and added taf directives
2149      - double precision constants to reduce the g77 (Linux)
2150        to F77 (SGI) differences reported in release1_p8
2151    o tools/genmake
2152      - added SGI options
2153    o verification/testscript
2154      - updated to that of checkpoint47a_post
2155    o verification/global_ocean.90x40x15/input/eedata
2156      - modified for SGI f77 compatibility
2157    o verification/lab_sea
2158      - added description of sea-ice model
2159      - added missing matlab routines
2160      - added test of thermodynamics parallelization
2161    
2162    checkpoint47a_post
2163    o new pkg: aim_v23
2164     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
2165       for now, keep the same surface forcing as before.
2166     - Part-Cell implemented into AIM; check that Heat & Water are conserved
2167     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
2168     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
2169    o add diagnostic of surface correction term in monitor output
2170    
2171    o bulk_force and therm_seaice
2172    - Two packages:  bulk_force (Bulk forcing)
2173      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
2174    - Earlier integration from Stephaine Dutkiewicz
2175      and Patrick Heimbach.
2176    - Two ifdef statements for compile time,
2177       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
2178    
2179    checkpoint47
2180    differentiable version of checkpoint46n_post
2181    o bug fix in quasihydrostaticterms
2182    o * "clean" adjoint code (in terms of extensive recomputations)
2183        can now be obtained for all GMREDI options (i.e. for
2184        - GM_VISBECK_VARIABLE_K
2185        - GM_NON_UNITY_DIAGONAL
2186        - GM_EXTRA_DIAGONAL
2187        - GM_BOLUS_ADVEC )
2188      * However, wrong gradient check problem remains unsolved.
2189      * New CPP options have been introduced for different
2190        tapering schemes
2191    o external_fields_load now part of differentiation list
2192    o pressure needs multiple storing;
2193      would be nice to have store_pressure at beginning or
2194      end of forward_step, e.g. by having phiHyd global (5-dim.)
2195      (NB: pressure is needed for certain cases in find_rho,
2196      which is also invoked through convective_adjustment).
2197    o recomputations in find_rho for cases
2198     'JMD95'/'UNESCO' or 'MDJWF' are OK.
2199    o #define ATMOSPHERIC_LOADING should be differentiable
2200    o ini_forcing shifted to begining of initialise_varia
2201    o Incorporating QNVS line search routines into MITgcm
2202      (this is separate code, and therefore not under pkg)
2203      lsopt/, optim/
2204    o Updated verification/carbon/
2205      - #define GM_VISBECK_VARIABLE_K
2206      - GM_taper_scheme    = 'ldd97'    
2207    
2208    checkpoint46n_post
2209    Merging from release1_p8:
2210    o verification/natl_box:
2211      updating new external_fields_load routine
2212    o New package: pkg/seaice
2213      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
2214      The sea-ice code is based on Hibler (1979-1980).
2215      Two sea-ice dynamic solvers, ADI and LSR, are included.
2216      In addition to computing prognostic sea-ice variables and diagnosing
2217      the forcing/external data fields that drive the ocean model,
2218      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
2219      The implied surface heat flux is then stored in variable
2220      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
2221      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
2222      non-local transport term.  Because this call precedes model
2223      thermodynamics, temperature under sea-ice may not be "exactly" at
2224      the freezing point by the time theta is dumped or time-averaged.
2225      N.B.: fairly large differences in accuracy occur across
2226            different platforms/compilers; comparison between
2227            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
2228            generated output gives:
2229       T           S           U           V
2230      C D M    c        m  s        m  s        m  s        m  s
2231      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
2232      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d
2233      g d e n  d  n  x  n  .  n  x  n  .  n  x  n  .  n  x  n  .
2234    
2235      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
2236    o GAD:
2237      - generated new common blocks to account for call of
2238        same gad routines with differing traceridentities
2239        (needed to modify tracerIdentity indices in GAD.h)
2240      - generated separate common blocks for case useCubedSphereExchange
2241        (Department of Futurology)
2242      - parameter lists to gmredi_?transport: added tracerIdentity
2243      - added new key indices to tamc.h
2244    o external_fields_load:
2245      - added this routine to TAF list
2246      - needed to make some common blocks global and additional storing
2247        along the same lines as exf package (checkpoint_lev?_directives.h)
2248    o exf:
2249      updated external forcing package
2250      - bug fixes carried over from ecco-branch
2251        (missing OBCS_OPTIONS.h in two routines)
2252      - enable easy to use "no forcing".
2253      - added exf I/O for atmospheric loading
2254      - added exf I/O for runoff data
2255      - transfered scaling between exf <-> MITgcm to exf namelist
2256    o Adding new verification experiment global_with_exf.
2257      This verification experiment is almost identical to the
2258      global_ocean.90x40x15 experiment, except that it uses
2259      the exf (and cal) package instead of the
2260      external_fields_load routine (cf README file).
2261    
2262    checkpoint46m_post
2263    o modified testscript to return -- when there are no lines of "%MON" output
2264    o added new flag "quasiHydrostatic" for QH mode
2265      and new routine quasihydrostaticterms()
2266    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
2267      New routine: mom_u_coriolis_nh()
2268    o fixed sign of non-hydrostatic metric terms in u and v equations.
2269      Depend on correct sign of gravitySign.
2270    o added work.pc* to .cvsignore in aim directories using ifc
2271    o introduced flag for controllin non-hydrostatic metric terms
2272    o removed gravitySign from PARM04
2273    o switched to g77/ifc from pgf77 in aim experiments
2274    
2275    checkpoint46l_post
2276    o made convective adjustment work with pressure coordinates:
2277     - changed the direction of k-loop in convective_adjustment.F for the
2278       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
2279     - adjusted the reference pressure k-index in convective_adjustment.F
2280     - adjusted the convection condition in convect.F (in analogy to
2281       calc_ivdc.F)
2282     - convective_adjustment no longer computes anything on the halos
2283     - removed the warnings about negative salinity from find_rho.F and
2284       find_alpha.F; instead the new routine look_for_neg_salinity, called
2285       at the beginning of find_rho, find_alpha, and find_beta, does a
2286       check of the entire slice, if CPP-option
2287       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
2288    checkpoint46l_pre
2289    
2290    checkpoint46k_post
2291    o fixed the verification/global_ocean.90x40x15 experiment:
2292     - new bathymetry (the world according to A., JMC, and M.)
2293     - new initial fields and forcing fields (*.bin files)
2294     - new POLY3.COEFFS (for the next release one should switch to a full
2295       equation of state: JMD95P or MDJWF)
2296     - fixed several errors and redundancies in the data file
2297     - experiment uses looped cells
2298     - added matlab directory with diagnostic scripts for plotting of output
2299    
2300    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
2301     - read AIM physics parameters from a file (data.aimphys)
2302     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
2303    
2304    checkpoint46j_post
2305    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
2306    o move wVel computation at the end of the time step, in S/R integr_continuity
2307    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
2308    o update timeave pkg for wVel diagnostic.
2309    checkpoint46j_pre
2310    
2311    checkpoint46i_post
2312    o Clean up AIM package (and keep the results unchanged):
2313      include CPP_OPTION and use IMPLICT NONE in all routines ;
2314      declare all the variables _RL ; use _d 0 for all numerical constants.
2315      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
2316    
2317    checkpoint46h_post
2318    o cleaned up the use of rhoNil and rhoConst.
2319      - rhoNil should only appear in the LINEAR equation of state, everywhere
2320        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
2321        and the dynamical equations are all divided by rhoConst
2322    o introduced new parameter rhoConstFresh, a reference density of fresh
2323      water, to remove the fresh water flux's dependence on rhoNil. The default
2324      value is 999.8 kg/m^3
2325    o cleanup up external_forcing.F and external_forcing_surf.F
2326      - can now be used by both OCEANIC and OCEANICP
2327    checkpoint46h_pre
2328    
2329     Added code to convert surface volume flux (fresh water) into
2330     a mass flux when using P coordinates in the ocean (OCEANICP).
2331     Note: It assumes you have set rho0=rhoConst=density of fresh water.
2332    
2333    checkpoint46g_post
2334    o Include a new diagnostic variable phiHydLow for the ocean model
2335      - in z-coordinates, it is the bottom pressure anomaly
2336      - in p-coordinates, it is the sea surface elevation
2337      - in both cases, these variable have global drift, reflecting the mass
2338        drift in z-coordinates and the volume drift in p-coordinates
2339      - included time averaging for phiHydLow, be aware of the drift!
2340    o depth-dependent computation of Bo_surf for pressure coordinates
2341      in the ocean (buoyancyRelation='OCEANICP')
2342      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
2343        Theta, Salinity, and Pressure in the parameter list. This routine is
2344        presently contained in find_rho.F. This routine does not give the
2345        correct density for 'POLY3', which would be a z-dependent reference
2346        density.
2347    o cleaned up find_rho
2348      - removed obsolete 'eqn' from the parameter list.
2349    o added two new verification experiments: gop and goz
2350      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
2351    checkpoint46g_pre
2352    
2353    checkpoint46f_post
2354    o Enable tangent linear (forward mode) gradient checks:
2355      - extended active file handling to g_... files
2356      - added TANGENT_SIMULATION to theSimulationMode
2357      - extended grdchk package accordingly
2358    o added tangent linear setup in verification/carbon/code_ftl
2359    o added adjoint setup in verification/front_relax/code_ad
2360    
2361    checkpoint46e_post
2362    o Added new equation of state -> MDJWF
2363      - EOS of McDougall et al., 2002, JAOT, submitted
2364      - caveat: the equation of state is only valid for a smaller (more
2365        realistic?) range of values than JMD95P/Z and UNESCO
2366      - added masks to the calculation of pressure in store_pressure
2367      - added more check values for density in check_eos (ini_eos.F), some of
2368        the old check values are out of the range of the MDJWF-eos, so don't
2369        expect perfect matches for those
2370    checkpoint46e_pre
2371    
2372    checkpoint46d_post
2373    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
2374      'OCEANICP', also initialised field pressure correctly in ini_eos in the
2375      case of pressure coordinates. eosType='JMD95Z' in
2376      combination with buoyancyRelation='OCEANICP' now causes an error.
2377    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
2378      in find_alpha/beta.
2379    checkpoint46d_pre
2380    
2381    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
2382      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
2383    
2384    checkpoint46c_post
2385    o Changes necessary for ocean in p-coordinates
2386     -  Added new buoyancy relation = 'OCEANICP'
2387     -  Added new parameters = gravitySign (this used to be contained inside
2388        the factor dRdZ which I added when we first switched to R coordinates).
2389     X GM/Redi is not compatible (yet)
2390     X bottom drag and no-slip need to be debugged.
2391    checkpoint46c_pre
2392    
2393    checkpoint46b_post
2394    o Added new equation of state -> JMD95Z and JMD95P
2395      - EOS of Jackett and McDougall, 1995, JAOT
2396      - moved all EOS parameters into EOS.h
2397      - new routines ini_eos.F, store_pressure.F
2398    o Added UNESCO EOS, but not recommended because it requires
2399      in-situ temperature (see JMD95)
2400    o Modified formatting for knudsen2.f in utils/knudsen2 and added
2401      unesco.f to be used with POLY3
2402    checkpoint46b_pre
2403    
2404    checkpoint46a_post
2405    o Added (atmospheric) pressure loading
2406      - new field in FFIELDS.h, etc...
2407      - new cpp flag ATMOSPHERIC_LOADING
2408    o Changed hFacC to _hFacC in calc_phi_hyd.F
2409    o Added SHORTWAVE_HEATING to some files for consistency
2410    checkpoint46a_pre
2411    
2412    checkpoint46
2413    further merges from release1_p5
2414    o new ctrl package
2415      - adopted from ECCO environment to enable optimization
2416      - added Eliassen Palm fluxes to controls
2417    o added Eliassen Palm flux controls to gradient check package
2418    o cost package
2419      - Compatible with new ctrl package
2420      - added Eliassen Palm cost hooks
2421      - modif's of existing cost functions
2422    o Adjoint-related bug fixes in kpp:
2423      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
2424      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
2425    o autodiff package
2426      - flow directives:
2427        + new for S/R do_the_model_io
2428        + enhanced for S/R checkpoint
2429        + new gmredi.flow
2430      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
2431        disable adcommon.h/g_common.h by default.
2432      - fixed problem for adjoint of global_max
2433    o modified verification/carbon/
2434    o New setup for adjoint of global_ocean
2435    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
2436    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
2437    o incorporated hooks for sponge layer code (external_forcing.F)
2438    
2439    checkpoint45d_post
2440    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
2441    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
2442      (affects plume_on_slope "cg2d" output)
2443    o add new parameter deltaTfreesurf for free-surface time stepping
2444    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
2445    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
2446    o change phiMin in exp1 (to agree with documentation)
2447    o add new flags:
2448     - T,S forcing inside/outside Adams-Bashforth
2449     - turn off temp,salt advection and/or forcing
2450     - for each tracer, define internal flag for multiDimAdvection & A-B
2451    o monitor: change definition of KE to check conservation of Energy
2452    
2453    checkpoint45c_post
2454    o Removed f90 comments ("!")
2455    o Modified initialisations to enable exf package for MITgcm
2456      (without invoking ECCO_PACKAGE).
2457    o modifications to gradient check package (Martin Losch)
2458      - enable centered differences
2459      - modified format of standard output
2460    
2461    checkpoint45b_post
2462    o cleaned exchange calls in cg2d
2463    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
2464    o included CPP option SINGLE_LAYER_MODE in thermodynamics
2465      to configure barotropic setup (Martin Losch)
2466    o moved some initialisations within bi,bj loop in dynamics
2467      (TAF flow dependency)
2468    o in initialise_varia, moved call packages_init_variables
2469      before convective_adjustment_init
2470      (corresponding adjustment of TAF tape initialisation).
2471    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
2472    
2473    checkpoint45a_post
2474    o compute Rho over the whole domain (extend iMin,jMin indices)
2475    o specific exchange for X-slice domain (case Ny=1)
2476    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
2477    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
2478    
2479    checkpoint44h_post = checkpoint45
2480    o Fix to restore differentiability:
2481      place at which packages_init_variables is called in
2482      initialise_varia is crucial for reverse control flow.
2483    o modifications in GMRedi to enable stable adjoint
2484      (corresponding modif's in thermodynamics, dynamics)
2485    o added missing hook for sponge layer code in external_forcing
2486    o modified test cost functions
2487    o storing in gad_advection (plus removal of write(0,*)!
2488    o missing headers TR1.h added in convective_adjustment routines
2489    o errorMessageUnit set non-equal zero in eeboot
2490      (conflict on some platforms, e.g. IBM SP3)
2491    o modified carbon verif.
2492    
2493    checkpoint44h_pre
2494    o vertical grid option: allow to put the Interface at the middle between
2495      2 cell-centers ; replace delZ in pkg/kpp by drF.
2496    o GM Advective form: Tracers are advected using the residual transport (=
2497      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
2498    
2499    checkpoint44g_post
2500    o fix surface correction term in multiDimAdvection (affects plume_on_slope
2501      results) ; ifdef missing in thermodynamics.F
2502    
2503    checkpoint44f_pre,checkpoint44f_post
2504    o added PTRACERS package
2505      This allows an arbitrary number of passive tracers to be integrated
2506      forward simultaneously with the dynamicaly model.
2507      + Implemented so far:
2508        - basic forward algorithm (time-stepping, advection, diffusion, convection)
2509        - I/O and checkpointing
2510        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
2511      + Not implemented so far:
2512        - KPP
2513        - OBCS
2514      + No specific example supplied (yet) but global_ocean.90x40x15 has the
2515        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
2516        line in data.pkg.
2517      + This package is disabled by default since it increases storage.
2518    
2519    
2520    o testscript: added -cleanup option
2521    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
2522                 b) enable to filter 2D fields.
2523    
2524    checkpoint44e_pre,post
2525    o re-wrote convective adjustment to use pre-calculated weights
2526      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
2527      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
2528      Original calls to convect() still in place.
2529    
2530    chkpt44d_pre,post
2531    o added missing EXCLUDE_MONITOR flags
2532    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
2533      (incompatible typ in MIN/MAX expressions caused problems
2534      on IBM SP3)
2535    o in genmake added variable MAKEDEPEND
2536      plus resetting for case SunOS
2537    o added timer_stats.c routine for IBM SP3
2538    o removed variables in dynamics
2539    !!! I forgot to create tag chkpt44d_pre !!!
2540    !!! But chkpt44d_pre = chkpt44c_post    !!!
2541    
2542    o real fresh water flux implemented with non-linear free-surface.
2543    
2544    chkpt44c_pre,post
2545    o few fix (mask in shap_s2, EmPmR in external_field_load,
2546      USE_NATURAL_BCS in solve_for_P);
2547    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
2548    
2549    checkpoint44b_pre/_post
2550    o merge of relevant stuff from the ecco-branch:
2551      - genmake: removed $S64 overwrite for case SunOS
2552      - pkg/exf: update and corrections for field swapping and obcs
2553      - pkg/ecco: parameter lists for the_model_main, the_main_loop
2554                  harmonized between ECCO and MITgcm
2555      - pkg/autodiff: added flow directives for obcs, mdsio_gl_slice
2556                      updated checkpointing_lev... lists for obcs
2557      - model/src: minor changes in forward_step, plot_field
2558                   added directive for divided adjoint in the_main_loop
2559      - pkg/mdsio: added mdsio_gl_slice
2560    
2561    o check parameters & config (chkpt44a_pre,post)

2569    o improve and extend diagnostics (Monitor, TimeAve with NonLin-FrSurf)
2570    o added some stuff for AD
2571    
2572    checkpoint43
2573    o added two new advection tests
2574    o added global 4x4 degree ocean test
2575    o added test of H&S94 with free surface on cube
2576    o some final mods for gradient check, adjoint,...
2577    
2578    checkpoint42
2579      Fixed AD-related problems:
2580    o Store directives up-to-date with re-arranged Adams-Bashforth
2581      (mainly thermodynamics.F)
2582    o New store directives for multi-dim. advection schemes
2583      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
2584      * new common block and key passkey
2585      (mainly gad_advection.F)
2586    o Modified store directives for split of dynamics/thermodynamics
2587      for the case ALLOW_KPP
2588    o Cleaned argument list for timestep_tracer.F
2589    
2590    checkpoint41
2591    o re-formatted/added comments in prologues of key subroutines
2592      to work with protex
2593    
2594    checkpoint40
2595    o moved calc_gs, calc_gt and calc_tr1 back to model/src
2596    o added FLT (floats) package from Arne along with demo. experiment
2597    o re-arranged Adams-Bashforth scheme for tracers to allow easier
2598      implementation of forward-in-time forcing terms
2599    o more mods for non-linear free-surface including new variable
2600    o modified multi-dim method to work on cube
2601    o bug fix in KPP (from DM)
2602    
2603    checkpoint40pre9
2604    o added DST advection schemes
2605    o fix MPI bug on SGI's
2606    o modifications for non-linear free-surface
2607    o fixed conditionals for fixed flow/passive tracer only mode
2608    o added tension/strain form of stress tensor
2609    o changes to commenting of arguments for TAF/TAMC
2610    o added/updated many matlab scripts
2611    o added multi-dimensional advection method for tracers
2612      
2613    checkpoint40pre8
2614    o new package rw/
2615      Added method for dumping intermediate local arrays:
2616      mdsio_writetile - same as mdsio_writefield except works from inside
2617                        bi,bj loop
2618      mdsio_writelocal - same as mdsio_writetile except works for local
2619                         arrays
2620      write_local_r? - higher-level wrapper for mdsio_writelocal
2621      Controlled by diagFreq. Defaults to zero (ie. no dumps)
2622      Example given at end of mom_vecinv.F that dumps some local arrays.
2623    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
2624      control flux-form versus vector invariant code.
2625      Switch is runtime flag vectorInvariantMomentum (defaults to false)
2626      or genmake -DISABLE ...
2627    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
2628      (additional storing is now needed for case vecinv;
2629      currently nothing implemented to switch this storing off
2630      in case fluxform is used since no CPP flag available).
2631    
2632    checkpoint40pre7
2633    o bug fix in dynamics.F
2634      calc_viscosity called before k=1,Nr loop.
2635    o added some #ifdef's ALLOW_PASSIVE_TRACER
2636    o cleaned initialisations in ctrl_map_ini
2637      related to TAF
2638    
2639    checkpoint40pre6
2640    o split dynamics into thermodynamics & dynamics
2641    o corresponding split of calc_diffusivity into
2642      calc_diffusivity, calc_viscosity
2643      (kpp_calc_diff, kpp_calc_visc).
2644    o Added diffkr, kapgm to control variables
2645    o bug fix in gmredi_slope_limit for ldd97
2646    
2647    checkpoint40pre5
2648    o proper initialization of Adams-Bashforth time stepping
2649      + uses forward step for very first step of model (iter=0)
2650    o re-generated *all* output since almost all output is modified by this
2651      change (sorry but we've been putting this one off for about 2 years)
2652      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
2653        *not* regenerated since they are already out of date and I don't
2654        want to create the impression that they are suddenly working.
2655    o removed KAP stuff for DEC's
2656    o modified/added many .cvsignore files in */code and */input
2657    o added new expt "solid-body.cs-32x32x1"
2658      + this uses an alternative form of ini_curvilinear_grid.F which
2659        is not necessarily any better than the current one...
2660    
2661    checkpoint40pre4
2662    o added re-initialisations of utrans,vtrans,rtrans in
