4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
8      affects the results (but none of the verification test uses this scheme).
9    o Adding some pkg/diagnostics capability to pkg/seaice
10      (will certainly be subject to changes)
11    
12    checkpoint58q_post
13    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
14      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
15      high_res_cube configuration by 4% on Columbia.
16    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
17      add (in global_with_exf/code) a version of EXF_INTERP_READ without
18      dynamical allocation (seems to work in multi-threaded).
19    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
20      single CPU io) so that TAF does not have to see EESUPPORT.h
21    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
22    
23    checkpoint58p_post
24    o obcs: stop if obcs is used with useCDscheme = .true.
25    o shelfice:
26     - fix a sign error so that no slip at shelfice interface works
27     - remove stop for combination non-hydrostatic code and shelfice. That does
28       not mean, that the results are correct, but at least they are numerically
29       stable
30    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
31    o added adjoint exch routined for all exch*3d* routines
32      and updated flow directives
33    
34    checkpoint58o_post
35    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
36      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
37    o change controling S/R for writing pickup file (new S/R do_write_pickup)
38      and clean-up reading/writing of pickup files.
39    o fix local version of read/write pickup (NH part) in rotating_tank/code
40    o simplify EXCH interface:
41     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
42     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
43    o added the regrid package
44    o shelfice:
45     - add a simple boundary layer scheme to reduce noise
46     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
47    
48    checkpoint58n_post
49    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
50       local variable (not in common block).
51    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
52      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
53      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
54        to work with SingleCpuIO.
55    o add "_d 0" to real constant of pkg/cfc subroutines ;
56       update exp. cfc_exemple & tutorial_cfc_offline output files.
57    o multi-threading and IO:
58      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
59        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
60      - barrier before and after reading.
61      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
62      - avoid using MDS_WRITELOCAL for LAND pkg output.
63      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
64        common-block variables ; Allows multi-threading with master-thread IO.
65    o change default MAX_NO_THREADS from 32 to 4 ;
66      and stop cleanly when MAX_NO_THREADS is too small.
67    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
68    
69    checkpoint58m_post
70    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
71       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
72    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
73       keep global_ocean.90x40x15 (for AD testing) with former secondary test
74       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
75    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
76        add MITgcm_tutorials (= code + all the tutorials)
77    o ecco, option to compute cost for total ssh (mean+anom)
78    o consistent with addition of ptracer and ssh in pkg/profiles
79    o profiles: adding ptracer and ssh
80    o testreport: change multi-test output-file name
81      (from output.txt.{name} to output.{name}.txt)
82    o profiles: now ok for mutli-tiles case
83    o seaice: add 4 parameters for different advection schemes for area,
84      (effective) seaice thickness, enthalphy, and snow height. Their default
85      is the standard parameter SEAICEadvScheme
86    o calc_gw:
87     - add cosFacU in zonal viscous flux (harmonic.visc.).
88     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
89       of tutorial_plume_on_slope.
90    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
91    o calc_gw: true flux-form, account for horizontal grid spacing.
92      update rotating_tank results, but not plume_on_slope (affected at
93      truncation level, 11 digits).
94    
95    checkpoint58l_post
96    o calc_gw:
97     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
98     - remove side-drag for now (need to fix it); update plume_on_slope results.
99     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
100    o commit code to make SST/SSS weights spatially variable
101      (based on either variable in-situ or variable initial T/S weights)
102    o pkg/ecco:
103      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
104        now based on horizontally varying weights wthetaLev, wsaltLev
105      * cost_averagesflags now returns year indices in addition to day, month
106      * sflux balance is performed on annual basis
107        (sflxumm, sfluxmm2, bal_sfluxmm)
108      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
109        including separate counting and multipliers
110    o pkg/rbcs
111      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
112    
113    checkpoint58k_post
114    o testreport:
115     - always build in dir. "build" (if not there, mkdir build instead of building
116       & running in input)
117     - run in dir run (if it exists), in build otherwise.
118     - call prepare_run (if input/prepare_run exists)
119     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
120    o pkg/exf modifications to interpolation and rotation routines for more
121       reasonable treatment of North Pole singularity: for tracers North Pole
122       value is set to northernmost zonal-mean value, for zonal velocity it is
123       set to zero, and for meridional velocity it is set to northernmost value.
124    o pkg/exf/exf_check_range.F
125     - add tile index to diagnostics and move stop statement to the very
126       end of the routine.
127    o pkg/diagnostics: (diagnostics_main_init.F)
128      define title of isomorphic variables according to the current config.
129    o pkg/thsice with pkg/seaice dynamics:
130    - fix domain of computation (interior only, required for exf) and do exchanges
131    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
132    o towards a standard way of dealing with multi-threading in MONITOR
133      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
134    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
135       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
136    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
137    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
138    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
139       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
140    o tracer advection:
141     - clean-up and simplify calc_common_factors.F
142     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
143       advection subroutine (but still not used within DST advection S/R)
144    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
145    
146    checkpoint58j_post
147    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
148      from file (collects calls previously in FORWARD_STEP)
149    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
150    o adjoint store dir. adjusted accordingly
151    o genmake2
152      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
153    
154    checkpoint58i_post
155    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
156      on wind stress (SEAICEstressFactor defaults to 1.)
157    o Total number of Timers is finite (<=40): comment out 2 non-essential one
158      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
159    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
160      on CS-grid: no longer loosing mass.
161    o exf & curvilinear-grid: no longer modify longitude xC & xG.
162    o pkg/ggl90: fix sloppy output and fix a bug
163    o pkg/seaice: added SEAICEuseEVPpickup parameter
164      - Set to false in order to start EVP solver with
165        non-EVP pickup files when using SEAICEuseEVP
166      - fix sign error in diffusion in seaice_calc_rhs
167    
168    checkpoint58h_post
169    * Modifications for bottom topography control
170      o replace hFacC by _hFacC at various places
171      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
172      o add non-self-adjoint cg2d_nsa
173      o update autodiff support routines
174      o re-initialise hfac after ctrl_depth_ini
175      o works for 5x5 box, doesnt work for global_ocean.90x40x15
176    * Adding verification for 5x5 box (4-layer) bottom topography control
177    
178    checkpoint58g_post
179    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
180       used for mean seasonal cycle, mean diurnal cycle); add an example
181       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
182    o pkg/ggl90:
183      - add parameter (minimum surface kinetic energy)
184      - fix bug (avoiding division by zero)
185    o couple pkg/thsice to pkg/seaice:
186      - modify advection in seaice to accomodate new scalar fields to be advected
187      - only muliDimAdection scheme work with seaice/thsice
188      - mapping of thsice-variables to seaice-variables, back and forth
189      - does not break the verification experiments, but does not give the
190        desired results either
191    o pkg/seaice
192      - make (default) second order advection a bit less confusing?
193    
194    checkpoint58f_post
195    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
196      to pkg/seaice):
197      - new routines thsice_map_exf and thsice_get_exf provide the interface
198      - add an additional formal parameter to thsice_solve4temp
199    o pkg/exf:
200      - add new fields wspeed, snowprecip (to be able to couple to thsice)
201      - correct Stefan-Boltzmann constant
202      - new parameter for longwave surface emittance
203      - separate some stuff from exf_bulkformulae into new routines  
204        exf_radiation, exf_wind
205      - add new parameters and constants: longwave emissivity for ocean, ice
206        and snow, evaporation parameters over ice
207      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
208        either wind from stress or stress from wind
209    o pkg/thSIce:
210    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
211    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
212       and THSICE_CALC_THICKN
213    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
214    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
215      to make debugging easier.
216    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
217    o pkg/bulk_force:
218      - clean-up comments and parameters ;
219      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
220    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
221      generate new output for test-experiment: aim.5l_cs.thSI
222    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
223      testreport accordingly
224    
225    checkpoint58e_post
226    o SEAICE_CGRID adjoint done
227    o R_STAR adjoint implemented.
228      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
229      * need to sort out init. of h0facc, etc.
230    o Make pkg/profile fully independent of ecco,cost, etc. stuff
231      to be able to use it in pure forward.
232    
233    checkpoint58d_post
234    o upgrade simple test-experiment to tutorial example:
235     step.1: duplicate the experiment and (step.2) will remove the old copy.
236      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
237      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
238      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
239      tutorial_global_oce_biogeo    <- copy of dic_example
240      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
241      tutorial_plume_on_slope       <- copy of plume_on_slope
242      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
243      tutorial_global_oce_optim     <- empty for now (David ?)
244      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
245     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
246    o correct a sign problem in cost_scat.F
247    o obcs and ptracers: fix boundary conditions for advections schemes
248      with larger stencil
249    o thsice adjoint: start
250    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
251      completeness
252    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
253      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
254    o ptracers adjoint:
255      * avoid extensive recomputatations
256      * fix missing re-init. of gptr (missed by TAF)
257    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
258      me to turn off the excessive output to STDOUT that this package produces
259    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
260      and add those terms in Vector-Invariant formulation.
261    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
262      if the control period (xx_hfluxperiod etc) is 0
263    o in profiles pkg, clean routines and fix details
264    o in ecco pkg, reading ssh data:
265      fix problem in case the model does not start at iter0=0
266    o fix mnc-pickup/restart for ptracers
267    o new package prifiles:
268      code to compute profile-based cost by Gael Forget
269      (modifs in ecco, ctrl, autodiff)
270    o Benign bug fix in initialization (spotted by M. Mazloff) of
271      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
272    
273    checkpoint58c_post
274    o adjoint: finish NLFS adjoint and provide reference output in
275      verification/global_ocean.90x40x15/results_ad_nlfs
276    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
277      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
278      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
279      with SEAICE_CGRID defined.
280    o move calendarDumps from "data" to "data.cal" and clean-up the code
281      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
282    o add useEXF & useCAL flags (for now, set in hard-coded way)
283    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
284      (were missing in NH mode, and wrong in quasihydrostatic mode).
285      waiting for Chris updated version of calc_gw to add those CALLs.
286    o fix bug in quasihydrostatic S/R ;
287      add a test for this option: global_ocean.90x40x15.qshyd
288    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
289      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
290    o add on/off flag useOffLine for package OFFLINE
291    o seaice:
292      - modify advection so that it works also on the C-grid
293      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
294        problem in multi-tile runs with C-grid
295      - add flags for clipping ice velocities and/or masking solver forcing
296      - fix drag (ocean on ice) formulation and a bug that caused noise in the
297        C-grid solver
298      - added a few comments to seaice_diffusion.F
299      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
300        are now exclusive)
301      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
302        required re-ordering the code a little:
303       + make DAIRN global variable (defined in SEAICE)
304       + move computation of the viscosities eta and zeta into a new separate
305         routine (because I need to recompute them in seaice_ocean_stress.F)
306    
307    checkpoint58b_post
308    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
309      update output.txt of exp. aim.5l_cs.thSI
310    o various mnc cleanups and improvements:
311      + shrink lookup tables by factor of ~4
312      + better error reporting when running out of lookup space
313      + able to handle longer path/file names (up to 500 chars)
314    o adjoint:
315      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
316      - TBD: "hidden" mom_vecinv recomp. in dynamics
317    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
318     (allow to differentiate between forcing components using new integer flags:
319      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
320     and add new flag to put Dissipation tendency out of Adams-Bashforth.
321    o ecco
322      - enable trend removal from SSH anomaly obs.
323    o adjoint
324      - a fix for PmEpR when #undef EXACT_CONSERV
325      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
326      - try to fix "hidden" recomp. in forward_step for NLFS
327        (NLFS seems broken sometimes after I checked it in)
328    o seaice:
329     - add c-grid version of the dynamic solver:
330       + three new routines that are the c-grid substitute lsr, dynsolver
331         and ostres
332       + put a few fields that were local to dynsolver into global common
333         blocks, so that I can move the computation of stresses etc into
334         seaice_lsr (saves coding but may break the adjoint).
335     - replace more hardwired parameters by runtime parameters
336     - add ice masks that mask the rhs of the implicit solvers where there
337       is no ice (commented out in seaice_dynsolver, because i am not sure
338       if this works properly), eventually this should replace the clipping
339       of ice velocities in seaice_dynsolver to +/-40cm/s.
340    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
341      include it only where its needed
342    o move balancing of fluxes before the call of external_forcing_surf
343    o seaice:
344      - correct units of turning angles (now they are really in degrees)
345      - move computation of GWATX/Y out of main routine into dynsolver
346      - initialize GWATX/Y in seaice_init
347    o Apply mask on Fresh-Water flux (needed for SSH forcing).
348      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
349    o seaice: add runtime flags for turning angles (default to zero)
350    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
351      and trend from exf forcing and ctrl control adjustments
352    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
353      (since checkpoint57x_post)
354    o change the default rotation period to 86164.s = the Earth rotation
355    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
356      and based on a reference stratification. Tested within hs94.cs-32x32x5.
357    o seaice advection: add code for choosing between the default (2nd order
358      central differences) and multiDim advection schemes provided by
359      pkg/generic_advdiff
360    o seaice:
361      - removed all references to SEAICE_GRID.h fields from
362        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
363        (cubed-sphere configuration will change a little)
364      - grid computations in seaice_init are obsolete now.
365      - cleaned up code a little so that is easier to read (hopefully).
366      - added new (better?) discretizations of default advection and diffusion
367        (turn on with SEAICEuseFluxForm)
368      - replace 1 in 3d global fields by kSurface in growth.F
369      
370    checkpoint58a_post
371    o seaice:
372      - bug fix in advect.F
373    o shelfice:
374      - separate shelfice load anomaly from pload (breaks with time
375        dependent forcing), => introduce constant field shelficeLoadAnomaly.
376        Its default is 0., but it may be computed more cleverly from (unknown)
377        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
378        done offline. A good approximation of the pressure load anomaly is
379        necessary to avoid large initial adjustment processes underneath
380        deep-reaching shelfice.
381      - small fix in ISOMIP shelfice_thermodynamics
382      - add more sophisticated thermodynamics of Hellmer (1989), this is
383        now the default
384      - give a few constants more intuitive names
385    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
386      if bulk formulae are used in long integration (especially EmPmR). Turn
387      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
388      if balancePrintMean, the imbalance that is substracted is printed to
389      STDOUT.
390    o fix bug (typo) in obcs_apply_eta.F
391    o add a new package shelfice which enables us to model the circulation
392      underneath shelf-ice with draughts of hundreds of meters.
393     - works
394     - to do: + include improved thermodynamics
395              + check whether kSurfC (from model/inc/SURFACE.h) can be used
396                instead of new field kTopC
397              + can we use topoFile, Ro_surf and existing code in ini_depth.F
398                instead of new field R_shelfIce and new code in ini_depth.F
399                and ini_mask_etc.F?
400              + adjust vertical mixing schemes?
401    o seaice pkg:
402     - add a cpp-flag to include a simple formula for a salinity dependent
403       freezing point of sea water at the surface
404     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
405       meridional stresses are now different (and hopefully correct)
406    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
407       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
408       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
409    o pkg/diagnostics: add options and parameters for regional-statistics
410       diagnostics ; define regions by reading a region-mask from a file
411       (might add other options later)
412    o pkg/bulk_force:
413     - add option and parameters to use AIM surface-flux formulae.
414     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
415       others forcing fields (defined in PARM05, parameter file "data") are loaded
416       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
417     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
418     - use the right EXCH call for uwind,vwind (to work on CS-grid).
419     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
420       and parameters (note: calcWindStress replaces .NOT.readwindstress).
421     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
422    
423    checkpoint58
424    o add "--embed-source" option to genmake2 which, when the supporting
425      tools can be compiled (as determined by genmake2) will turn on the
426      embed_files package which then embeds the entire MITgcm source code
427      (*.[fFhc] + Makefile) used for the build within the executable
428      - requested by CNH but off by default
429      - adds a paltry <9MB to the mitgcmuv executable in most cases
430      - only writes the output when useEMBEDSRC in eedata is true
431    o clean up 3-dim. relaxation codes:
432      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
433      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
434      * Thanks to Tom Haine for testing!
435    
436    checkpoint57z_post
437    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
438      affects output (@ truncation level) of exp. plume_on_slope ; updated.
439    o fix the pickup behavior for obcs in combination with ptracers
440    o fix a bug in ptracers_external_fields_load
441    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
442      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
443    o transfered surface NH pressure to eta field (if exactConserv).
444    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
445         and update lab_sea output.txt file.
446    o completing 3-dim. relaxation code: additional term
447         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
448      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
449      * At compile time, in "EXF_OPTIONS.h" set
450          #define  ALLOW_CLIMTEMP_RELAXATION
451          #define  ALLOW_CLIMSALT_RELAXATION
452      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
453          tauThetaClimRelax3Dim = 15552000.0,
454          tauSaltClimRelax3Dim  = 15552000.0,
455      * 3 cases:
456          1) Use a constant-in-time 3-dim. field
457          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
458          3) Real-time relax. to time-evolving prescribed field
459    o Adding Laplacian-type smoothness constraint on
460      initial and boundary (forcing) controls (ic, bc)
461      * enable at compile-time via
462        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
463      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
464      * Absolute scale somewhat unclear so far
465      * no area weighting was included since no other cost term does so far
466    
467    checkpoint57y_post
468    First step for a NLFS adjoint
469    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
470    o new init. routines for calc_r_star, calc_surf_dr
471    o still need to deal with ini_masks_etc
472    o testreport seemed happy
473    checkpoint57y_pre
474    
475    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
476    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
477    o add new offset feature to offline pkg (plus minor cleanup)
478    o cfc fixes for final year of integration
479    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
480      be in GCHEM_OPTIONS).
481    
482    checkpoint57x_post
483    o fix testreport Pb in multiple test experiment.
484    o cleanup our namelist syntax in verification:
485      - make it more F95 standards compliant (some work still needed)
486      - allows the vast majority of our tests to work with gfortran
487    o Non-Hydrostatic:
488     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
489     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
490    o Allow to apply AB on T,S rather than on AB(gT,gS):
491     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
492     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
493       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
494     - need a "clever" read_pickup to restart from the other AB formulation
495    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
496    o remove some unused variables (reduces number of compiler warnings)
497    o adjoint
498      * Disable useVariableViscosity for adjoint for time being
499        (there are a number of extensive recomputations)
500      * Initialize certain variables needed for adjoint
501    
502    checkpoint57w_post
503    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
504                 fix the singleCpuIO RS version of MDSWRITEFIELD
505       and add a WARNING if using globalFiles=T with multi-processors.
506    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
507      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
508    o tracer advection scheme:
509      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
510       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
511       was not very convenient).
512      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
513       (further tests needed for the implicit DST & Flux-Limiter schemes).
514    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
515      and sRef for convenience, handy, when you want to initialize
516      ptracers in a large domain with a constant non-zero value. Also,
517      untangle ptracers_init.F a little.
518    
519    checkpoint57v_post
520    o change dome exp. to use variable viscosity in side-drag terms.
521    o remove all the files from the cfc_offline test since they are now
522      incorporated into tutorial_cfc_offline which has been producing
523      identical results for a few days of testing
524    o add new parameter: sideDragFactor to enable half-slip-side BC
525      and change side-drag S/R to use viscosity from mom_calc_visc
526      (can switch back by setting sideDragFactor=0.); affects results at
527      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
528       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
529    o vorticity & strain are now computed without masking, to account for
530      no-slip-side BC in variable viscosity calculation ; mask is applied
531      anyway later on, before computing advection/coriolis terms.
532    o modify exp4 to test new obcs support for reading from external files
533      and for passive tracers
534    o fix behavior of ptracers_monitor when monitor output is written to a
535      netcdf-file; still not independent of monitor.F (writes in the same
536      file).
537    o change default value of tRef (put a uniform, meaningful value for ocean
538      & atmos) and initialize sRef (was missing, as Martin mentioned).
539    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
540      to be proportional to enstrophy dissipation length.  Thus,
541       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
542      This is now consistent with Smagorinsky and with the manual.
543    
544    checkpoint57u_post
545    o OBCS and PTRACERS: add open boundary support for passive tracers
546      - either use homogenous (pseudo) v.Neumann conditions or prescribe
547        OB-values from file; this is not different from the way theta and salinity
548        are treated
549      - however, Orlanski-radiation conditions are not supported, and the model
550        will stop if you use pTracers and Orlanski at the same time.
551      - beefed up the rountine obcs_external_fields_load: now only those open
552        boundary values are overwritten with values from files for which there
553        are really files, otherwise the OB-fields remain untouched. This makes
554        it possible to use different OBs at different ends of the domain (as
555        with EXF)
556    o reduce number of exch calls in shap_filt (s2).
557    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
558      truncation level) 4/5 MLAdjust test results (11&12 digits match).
559    
560    checkpoint57t_post
561    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
562    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
563      same truncation, independent of the face number: affects affects several
564      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
565    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
566      note that biharmonic viscosity + no-slip was not tested in any experiment.
567    o fix bug in non-linear free-surf side-drag ; generate new output for
568      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
569    o make mnc honor the writeBinaryPrec flag for most kinds of output
570    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
571    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
572      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
573    o add brackets in multi-terms sum to get same truncation, independent of
574      the face number (manage to get exactly same value of gU,gV at the cs-edge)
575      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
576    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
577      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
578      a maximum grid-scale Reynolds number.  Also, changes all length calculations
579      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
580      Suggested values of viscosity parameters found in mom_calc_visc.
581      Many new viscosity diagnostics available.
582    
583    checkpoint57s_post
584    o Add clearing-house for viscosity calculations, mom_calc_visc and
585      correct numerous bugs in LeithD and Smagorinsky discretizations.  
586      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
587      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
588      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
589      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
590      The Strain-Tension form is now called with useStrainTensonVisc=.true.
591      ViscAhStrain and viscAhTension are now retired.
592    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
593    o In response to JMC's bug report, genmake2 now ignores any soft-links
594      that it finds in the *current* directory when searching for files.
595      Soft-links found in any other source directories will still work as
596      they did before.
597    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
598      a C routine to unlimit the stack size
599    o mnc-ify pkg/aim snapshot vars
600    o mnc-ify pkg/land as requested by Daniel
601    o various changes to mnc including:
602      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
603      - output can now be grouped so that all files within a group
604          change the ITER portion of their names in lock-step together
605      - can now read ("global") PER-FACE (in addition to PER-TILE) files
606          and works with both EXCH1 and EXCH2 (but needs more testing)
607      - writing works for all verification test cases w/ g77 on Linux
608    
609    checkpoint57r_post
610    o make MNC variable initialization happen earlier
611    o add diagnostics for (almost) each term of the momentum Eq.
612    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
613    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
614    o remove MINIMAL_TAVE_OUTPUT option ;
615      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
616    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
617      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
618    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
619    o add time-dependent SST, SSS control
620    o cost terms in ecco/ modularized (new cost_generic.F)
621    o cost_averages routines are modularized (new cost_averagesgeneric.F)
622    o new infrastructure for seaice model vs. obs misfits in seaice/
623      * driver from the_main_loop.F is seaice_cost_driver.F
624      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
625      * gradient check in Exp. 6a of natl_box_adjoint/
626    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
627      (see README file)
628    
629    checkpoint57q_post
630    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
631    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
632      - bug was reported by Jean-Michel and Ian Fenty
633    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
634      update exp. cpl_aim+ocn output.
635    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
636      Needed for high-res. runs with large global files
637      to be able to limit tapelev size
638    o Changed some tests for adjoint:
639      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
640      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
641      * global_ocean.90x40x15/ back to default 3-level checkpointing
642    o Modifications to enable scripted COMMON to MODULE conversion
643      * verification/OpenAD/code/ has necessary scripts and description;
644      * converts, compiles and runs successfully;
645    
646    checkpoint57p_post
647    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
648    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
649      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
650    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
651    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
652      (was already the case for dissipation with mom_vecinv,
653       and also the case for grad.PhiHyd when staggered-timeStep)
654      This will allow to put dissipation out-off the AB time-stepping.
655     Unfortunately, affects truncation error. Update output of exp. that "fails"
656      (cg2d matching number) and leave the others for later: front_relax(10),
657      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
658      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
659    
660    checkpoint57o_post
661    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
662      (2) its ready to be documented during the 20050801 DocFest
663    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
664      for ideal_2D_oce and lab_sea on linux_ia32_g77
665    o set to #undef CTRL_SET_OLD_MAXCVARS_30
666      in global1x1_tot/code_seaice_adj to access indices 32, 33
667      (worth another tag)
668    
669    checkpoint57n_post
670    o adding precip control xx_precip 32
671    o adding swflux control xx_swflux 33
672    o Replacing 10 forcing penalty cost routines by 1 generic.
673    o Implementing partitioning in time-mean and variable adjustment
674      for atmos. state.
675    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
676    o in natl_box_adjoint:
677      * updated exp 1 to 10
678        (but does not have time-mean vs. variable split results yet)
679    o updated global1x1/*_seaice_adj/
680      to incorporate latest changes
681    o enable useSingleCpuIO for mdsio vector routines
682      (applies in particular to tapelev I/O)
683    o removed inefficient K-loop in all active_file*control*.F
684    
685    checkpoint57m_post
686    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
687      and advect_cs (use EXCH-2 and standard cs-32 grid files).
688    o pkg/exch2: filling of face-corner halo regions is optional
689      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
690    
691    checkpoint57l_post
692     tag before updating tutorials (pre-release-2)
693    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
694       for output and interpolation of input fields onto model grid)
695    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
696       Affects results of exp. rotating_tank ; update output.txt.
697    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
698          and taking the square quantity and/or using a fraction-weight field.
699    o fix aim_diagnostics_init.F mate numbers.
700    o add mnc output capability to diagnostics/diagstat and update
701      our cvsignore files for the ACSII output generated
702    
703    checkpoint57k_post
704    o lab_sea now uses diagnostics package and provides a suite of
705      new EXF diagnostics output.
706    
707    checkpoint57j_post
708    o exf
709      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
710        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
711        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
712      * extended diagnostics output
713        - now includes all EXF variables
714        - hs, hl moved to common block
715        - separate S/R for diagnostics, called after ctrl vector is added
716        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
717        - EXFqnet contains true Qnet (i.e. includes qsw)
718      * updated verif. lab_sea, global_with_exf
719      * Rearranging hflux (exf_mapfields -> exf_getforcing)
720        to ensure that diagnostics sees a true EXFqnet
721    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
722    o diagnostics pkg: change pointers so that 1 diagnostic can be used
723      several times with different frequencies.
724    o mnc-ify the thsice package as requested by Daniel Enderton
725      - the monitor--MNC output needs work
726      - many attributes need to be added (most are currently blank)
727    o mnc-ify theaim_v23 package as requested by Daniel Enderton
728      - many attributes need to be added (most are currently blank)
729    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
730    o add Sadourny like discretization to the 4th.O vorticity advection scheme
731    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
732      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
733         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
734    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
735     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
736    
737    checkpoint57i_post
738    o Diagnostics package was changed: diagnostic allocation is now deactivated
739      by setting an empty file name in the namelist (used to be by setting 0 frequency)
740    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
741      add 1rst Order upwind vertical Shear.
742    o add a quick fix for A/B checkpointing in OFFLINE mode
743    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
744      end-run around the C/Fortran linking horror in eesup/src/timers.F
745    o added pkg/runclock: allows user to terminate run based on wall clock
746    o added non-hydrostatic scaling parameter: nh_am2
747    o pkg/my82: futile attempt to make results compiler-independent by adding
748      some "_d 0", etc. no effect.
749    o for mnc output, fill the 'T' coordinate var with myTime and create a
750      separate 'iter' variable for iteration count
751    o pkg/diagnostics:
752      add new capability: output of Global/Regional & per-level statistics ;
753      tested against monitor output (including land & thSIce) on various exp.
754    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
755    
756    checkpoint57h_done
757      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
758      data.diagnostics, data.gchem, data.ptracers) is done.
759    
760    o pkg/diagnostics: prepare for Global/Regional statistics.
761      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
762    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
763      and rename it: DIFFERENT_MULTIPLE
764    
765    checkpoint57h_post
766    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
767    o pkg/diagnostics: change output frequency, now in seconds (instead
768      of Nb of iterations). This requires to change data.diagnostics.
769    checkpoint57h_pre
770    
771    o in mnc, let the user create the output dir if both mnc_outdir_date
772      and mnc_outdir_num are false
773    o add fflags() to pkg/diagnostics which allows one to specify, on a
774      per-file basis, the file precision [default behavior is unchanged]
775    o added diagnostics to pkg/kpp, including computation of mixed layer
776      depth based on a temperature/density criterion
777    o updated verification/natl_box to test the new pkg/kpp diagnostics
778    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
779    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
780    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
781      not mnc -- this mistake was found by JMC and is now corrected
782    
783    checkpoint57g_post
784    o add Adams-Bashforth 3rd Order time stepping:
785      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
786      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
787    checkpoint57g_pre
788    
789    o make lambda[Theta,Salt]ClimRelax spatially varying
790      (default remains spatially uniform constant based on tau)
791    o added new control variables
792      * init. uVel, vVel, etanN
793      * lambda[Theta,Salt]ClimRelax
794    o separate masks used for ctrl_pack/unpack 'from write_grid' output
795      (suggested by G. Forget)
796    
797    checkpoint57f_post
798    o add parameter "baseTime" = model base time = time at iteration zero
799      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
800      account for baseTime shift
801    o move Coriolis arrays from PARAMS.h to GRID.h
802    checkpoint57f_pre
803    
804    o mnc-ifying the seaice package
805    o introduced an alternative length scale calculation for use in the limiting
806      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
807    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
808    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
809      as well as grad(vort3).  Made it compatible with both approximate form
810      for the cubed sphere and full form of these gradients.  Added flag
811      useFullLeith to select between approximate and full form.  
812    o add "d0" in getcon.F to reduce differences between compilers/platforms
813      update output.txt of exp. fizhi-gridalt-hs
814    o change port_rand funtion to allow to set the seed.
815    o fix obscure MNC bug involving conversion between reals and integers
816      - it caused no problems with certain (eg. gcc, ifc) compilers but the
817        new version is now more standards-compliant
818    o adjoint-related modifications
819      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
820      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
821      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
822    
823    checkpoint57e_post
824    o Adding eddy stress controls a la Ferreira et al.
825    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
826    
827    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
828      update output.txt of exp. fizhi-gridalt-hs
829    o add more "Z" dimensions and associated coordinate vars to MNC
830    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
831    o parameter calendarDumps: when set, approximate months (30-31 days) and years
832      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
833      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
834      months and years.  Requires pkg/cal.
835    o diagnostics: add pickup functionality
836      - off by default for backwards compatibility
837      - current version only uses MDSIO -- MNC will be added
838    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
839    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
840    
841    checkpoint57d_post
842    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
843    o modify verification/ideal_2D_oce so that it tests the creation of mnc
844      output from the diagnostics package
845    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
846    o make genmake2 more portable by using ".$FS" instead of ".f" for more
847      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
848    o add coordinate variables to the MNC output from the diagnostics package
849    o change MNC-flags default value: true when useMNC=TRUE
850    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
851      the ability (off by default) to read the grid information using MNC
852    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
853    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
854    o do snap-shot diagnostics at the middle of the time-interval (instead of
855      at the end).
856    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
857      new test for AIM with thSIce + slab-ocean
858    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
859    o move state variable diagnostics to the beginning of the time step ;
860      (note: still needs some work specially for snap-shot diagnostics)
861      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
862    
863    checkpoint57c_post
864    o Change testing option (-ieee) to get closer agreement between g77 & ifort
865    o generate new output.txt files on faulks with g77 & the new -ieee option
866    checkpoint57c_pre
867    
868    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
869      update output.txt of exp. global_ocean.90x40x15
870    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
871      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
872    o add saltFlux(+File) forcing capability with periodicExternalForcing
873    o allow to use pkg diagnostics for GM-Redi & ThSIce output
874    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
875    o improvements for the MNC output from DIAGNOSTICS:
876      - correct handling of the unlimitied dimension
877      - all dims now have associated coordinate variables
878      - variables located at U, V, and Corner ("Z") points are now written
879        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
880        *all* data points are output
881    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
882    o added pkg/seaice/seaice_monitor.F
883    o mdsio_readfield.F can now read files visible only to master MPI process.
884    o pkg/seaice: some test code for ice-modified ocean stress
885    o exf_getffields interpolation defaults to bilinear for all scalar forcing
886      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
887      spurious negative numbers for precipitation and humidity.  Will cause
888      some small numerical differences for integrations using pkg/exf/exf_interp.F.
889    o pkg/ctrl/
890      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
891        May be enabled via doPackDiag
892      *  introduce z-scaling of
893         + gradient (doZscalePack) and
894         + control (doZscaleUnpack)
895    o pkg/mdsio/
896      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
897      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
898    
899    checkpoint57b_post
900    o simplify options in diagnostics_fill arguments (remove weird combinations)
901    o fix MNC coordinate variables so that they now contain per-face index
902      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
903      general, EXCH2 grids are only aligned to a "local" coordinate system
904    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
905    o Implement instantaneous output within pkg diagnostics:
906      setting a negative frequency in data.diagnostics produces
907     "snap-shot" output (as opposed to time-average if freq > 0)
908    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
909      NOTE: change ptracer diagnostics name: use 2 characters to work with
910            more than 9 tracers. Add also diagnostics of advect & diffus flux.
911    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
912      becomes the coordinate variable for the 'T' dimension
913    o add CF-style coordinate variables to MNC
914      - just a first cut:  numbers are meaningless on the cubesphere and
915        missing along the T axis but otherwise it works!
916    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
917    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
918    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
919      this is based directly on what the model compute, so that the content of
920      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
921    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
922    o clean up build options files for SunOS, in particular
923      - remove -traditional from xmakedepend
924      - change -xarch=v9 to -xarch=native for f77
925      - restore use of make (not gmake)
926      - add CC=gcc if using g77
927    o changes per discussion of AM, JMC, & EH3 today:
928      - move redundant "grid" variables out of "state" -- in preparation of
929        creating proper CF-style coordinate variables and in recognition
930        that any/all grid variables can be easily copied (eg. w/NCO) from
931        the grid files into any of the other NetCDF files
932      - *always* output grid variables with MDSIO (this will eventually be
933        changed)
934      - output MNC grid file if useMNC is true
935    o every instance of _END_MASTER() has been found and replaced with
936      _END_MASTER( myThid ) in order to satisfy certain picky Sun
937      preprocessors
938    o re-arrange diagnostics pkg initialisation:
939     - allow each package to extend the available diagnostics list
940     - add some checking and fix small problems (multi-threaded, ...)
941     - new S/R diagnostics_fill (replace fill_diagnostics):
942       look through the short list of active diag. (instead of the long list)
943       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
944    
945    checkpoint57a_post
946    o this set of changes restores TAMC compatibility
947      tested for global_ocean.90x40x15 adjoint on trough
948      (what a pain)
949    
950    checkpoint57a_pre
951    o some modifs in tools/build_options for sunos
952    o call ctrl_pack for ctrl at end for optimcycle=0
953    
954    checkpoint57
955    o add horizontal bi-harmonic viscosity for vertical velocity
956      - new parameter viscA4W (defaults to viscA4)
957      - affects only non-hydrostatic code
958      - to be done: no-slip lateral boundary conditions
959    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
960    o implement Implicit Vertical advection for pTracers
961    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
962      (implemented also for implicit vertical diffusion & advection)
963    o OBCS: extend application of tracer open boundary conditions
964      to a strip beyond the boundary of width Olx/Oly
965    o add call monitor to TAF set of required calls (flow directives)
966      and include in natl_box_adjoint
967    o untangle a few ifdefs related to cost, ctrl, autodiff
968      untangel a few ALLOW_ECCO_OPTIMIZATION
969    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
970      (theta2, salt2 in ecco_cost_weights)
971    
972    checkpoint56c_post
973    o OBCS as control variables
974      - update ctrl_ad_diff.list, obcs_ad_diff.list
975      - remove balance of obcs controls from default
976      - fix index bug nobcs in ctrl_init
977      - fix dummy fields filen in ctrl_pack
978      - add dummy weights for obcs
979    o lsopt: comment out fort.94 output
980    o optim:
981      - remove unnecessary header files
982      - adjusted namelists
983      - add xerbla.F to Makefile
984    o exf:
985      - multiple modifications of exf_check_range
986      - unit change in exf_init_runoff from [m/year] to [m/s]
987    o mdsio:
988      - i/o-vector change debugLevel from debLevA to debLevB
989    
990    checkpoint56b_post
991    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
992      is called from DO_THE_MODEL_IO
993      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
994      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
995      - clean up PTRACERS_WRITE_TIMEAVE a little
996    o add another verification experiment that tests both the cfc-pkg and
997      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
998      reactive tendencies treated inline with regular timestepping
999    o testreport previously did a lousy job of comparing small numbers, so
1000      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1001      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1002      testreport.
1003    o ptracers_monitor: bug fix for MPI
1004    
1005    checkpoint56a_post
1006    o GCHEM: finish reorganizating the package
1007      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1008        (introduces another 3D-array for each passive tracer, but only if
1009        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1010        gchemTendency is not needed because the timestep is done separately)
1011      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1012      - GCHEM is now---more or less cleanly---separate from PTRACERS
1013      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1014        so clear to me how that should be done in a general way.
1015    o CFC: improve formatting of output in CFC_ATMOS
1016    o PTRACERS:
1017      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1018        that ALL experiments with ptracers enable can be checked. This makes
1019        GCHEM_MONITOR obsolete.
1020      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1021        monitorFreq
1022      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1023    o add PTRACERS (PTR0[1-5]) to testreport output
1024    o exf_check_range:
1025      * default changed to .TRUE.
1026      * will check values for niter0 if debLevA, every timestep if debLevB
1027      * STOP in exf_check_range if 'out of range'
1028      * range chosen generous to allow for potential extema
1029      TBD: a version with stricter range
1030           permitted range would be runtime parameters
1031  o GMredi:  o GMredi:
1032    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1033    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
# Line 11  o GCHEM: Line 1036  o GCHEM:

1038    - introduced a useGCHEM runtime flag and applied it everywhere.    - introduced a useGCHEM runtime flag and applied it everywhere.
1039      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1040        this flag is now only visible within GCHEM-pkg routines.
1041      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1042        be replaced by a 3D array that is computed before thermodynamics; for
1043        this, the tracer ID iTracer had to be included into the parameter list
1044        of ptracers_forcing
1045      - set up forward_step to call gchem_forcing, that will replace
1046        gchem_forcing_int in ptracers_forcing
1047      - cleaning up
1048  o small cleaning of exch2: remove files that are also in eesupp/src  o small cleaning of exch2: remove files that are also in eesupp/src
