4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
8      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
9      in natl_box (affects results @ truncation level: update output.txt)
10    o multi-threading and IO:
11      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
12      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
13        (needed to work with SingleCpuIO): tested in all verif. exp.
14    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
15      affects the results (but none of the verification test uses this scheme).
16    o Adding some pkg/diagnostics capability to pkg/seaice
17      (will certainly be subject to changes)
18    o ctrl: adding new control variables:
19      lwflux, lwdown, evap, snowprecip, apressure, runoff
20    
21    checkpoint58q_post
22    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
23      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
24      high_res_cube configuration by 4% on Columbia.
25    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
26      add (in global_with_exf/code) a version of EXF_INTERP_READ without
27      dynamical allocation (seems to work in multi-threaded).
28    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
29      single CPU io) so that TAF does not have to see EESUPPORT.h
30    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
31    
32    checkpoint58p_post
33    o obcs: stop if obcs is used with useCDscheme = .true.
34    o shelfice:
35     - fix a sign error so that no slip at shelfice interface works
36     - remove stop for combination non-hydrostatic code and shelfice. That does
37       not mean, that the results are correct, but at least they are numerically
38       stable
39    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
40    o added adjoint exch routined for all exch*3d* routines
41      and updated flow directives
42    
43    checkpoint58o_post
44    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
45      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
46    o change controling S/R for writing pickup file (new S/R do_write_pickup)
47      and clean-up reading/writing of pickup files.
48    o fix local version of read/write pickup (NH part) in rotating_tank/code
49    o simplify EXCH interface:
50     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
51     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
52    o added the regrid package
53    o shelfice:
54     - add a simple boundary layer scheme to reduce noise
55     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
56    
57    checkpoint58n_post
58    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
59       local variable (not in common block).
60    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
61      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
62      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
63        to work with SingleCpuIO.
64    o add "_d 0" to real constant of pkg/cfc subroutines ;
65       update exp. cfc_exemple & tutorial_cfc_offline output files.
66    o multi-threading and IO:
67      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
68        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
69      - barrier before and after reading.
70      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
71      - avoid using MDS_WRITELOCAL for LAND pkg output.
72      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
73        common-block variables ; Allows multi-threading with master-thread IO.
74    o change default MAX_NO_THREADS from 32 to 4 ;
75      and stop cleanly when MAX_NO_THREADS is too small.
76    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
77    
78    checkpoint58m_post
79    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
80       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
81    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
82       keep global_ocean.90x40x15 (for AD testing) with former secondary test
83       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
84    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
85        add MITgcm_tutorials (= code + all the tutorials)
86    o ecco, option to compute cost for total ssh (mean+anom)
87    o consistent with addition of ptracer and ssh in pkg/profiles
88    o profiles: adding ptracer and ssh
89    o testreport: change multi-test output-file name
90      (from output.txt.{name} to output.{name}.txt)
91    o profiles: now ok for mutli-tiles case
92    o seaice: add 4 parameters for different advection schemes for area,
93      (effective) seaice thickness, enthalphy, and snow height. Their default
94      is the standard parameter SEAICEadvScheme
95    o calc_gw:
96     - add cosFacU in zonal viscous flux (harmonic.visc.).
97     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
98       of tutorial_plume_on_slope.
99    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
100    o calc_gw: true flux-form, account for horizontal grid spacing.
101      update rotating_tank results, but not plume_on_slope (affected at
102      truncation level, 11 digits).
103    
104    checkpoint58l_post
105    o calc_gw:
106     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
107     - remove side-drag for now (need to fix it); update plume_on_slope results.
108     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
109    o commit code to make SST/SSS weights spatially variable
110      (based on either variable in-situ or variable initial T/S weights)
111    o pkg/ecco:
112      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
113        now based on horizontally varying weights wthetaLev, wsaltLev
114      * cost_averagesflags now returns year indices in addition to day, month
115      * sflux balance is performed on annual basis
116        (sflxumm, sfluxmm2, bal_sfluxmm)
117      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
118        including separate counting and multipliers
119    o pkg/rbcs
120      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
121    
122    checkpoint58k_post
123    o testreport:
124     - always build in dir. "build" (if not there, mkdir build instead of building
125       & running in input)
126     - run in dir run (if it exists), in build otherwise.
127     - call prepare_run (if input/prepare_run exists)
128     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
129    o pkg/exf modifications to interpolation and rotation routines for more
130       reasonable treatment of North Pole singularity: for tracers North Pole
131       value is set to northernmost zonal-mean value, for zonal velocity it is
132       set to zero, and for meridional velocity it is set to northernmost value.
133    o pkg/exf/exf_check_range.F
134     - add tile index to diagnostics and move stop statement to the very
135       end of the routine.
136    o pkg/diagnostics: (diagnostics_main_init.F)
137      define title of isomorphic variables according to the current config.
138    o pkg/thsice with pkg/seaice dynamics:
139    - fix domain of computation (interior only, required for exf) and do exchanges
140    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
141    o towards a standard way of dealing with multi-threading in MONITOR
142      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
143    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
144       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
145    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
146    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
147    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
148       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
149    o tracer advection:
150     - clean-up and simplify calc_common_factors.F
151     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
152       advection subroutine (but still not used within DST advection S/R)
153    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
154    
155    checkpoint58j_post
156    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
157      from file (collects calls previously in FORWARD_STEP)
158    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
159    o adjoint store dir. adjusted accordingly
160    o genmake2
161      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
162    
163    checkpoint58i_post
164    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
165      on wind stress (SEAICEstressFactor defaults to 1.)
166    o Total number of Timers is finite (<=40): comment out 2 non-essential one
167      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
168    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
169      on CS-grid: no longer loosing mass.
170    o exf & curvilinear-grid: no longer modify longitude xC & xG.
171    o pkg/ggl90: fix sloppy output and fix a bug
172    o pkg/seaice: added SEAICEuseEVPpickup parameter
173      - Set to false in order to start EVP solver with
174        non-EVP pickup files when using SEAICEuseEVP
175      - fix sign error in diffusion in seaice_calc_rhs
176    
177    checkpoint58h_post
178    * Modifications for bottom topography control
179      o replace hFacC by _hFacC at various places
180      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
181      o add non-self-adjoint cg2d_nsa
182      o update autodiff support routines
183      o re-initialise hfac after ctrl_depth_ini
184      o works for 5x5 box, doesnt work for global_ocean.90x40x15
185    * Adding verification for 5x5 box (4-layer) bottom topography control
186    
187    checkpoint58g_post
188    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
189       used for mean seasonal cycle, mean diurnal cycle); add an example
190       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
191    o pkg/ggl90:
192      - add parameter (minimum surface kinetic energy)
193      - fix bug (avoiding division by zero)
194    o couple pkg/thsice to pkg/seaice:
195      - modify advection in seaice to accomodate new scalar fields to be advected
196      - only muliDimAdection scheme work with seaice/thsice
197      - mapping of thsice-variables to seaice-variables, back and forth
198      - does not break the verification experiments, but does not give the
199        desired results either
200    o pkg/seaice
201      - make (default) second order advection a bit less confusing?
202    
203    checkpoint58f_post
204    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
205      to pkg/seaice):
206      - new routines thsice_map_exf and thsice_get_exf provide the interface
207      - add an additional formal parameter to thsice_solve4temp
208    o pkg/exf:
209      - add new fields wspeed, snowprecip (to be able to couple to thsice)
210      - correct Stefan-Boltzmann constant
211      - new parameter for longwave surface emittance
212      - separate some stuff from exf_bulkformulae into new routines  
213        exf_radiation, exf_wind
214      - add new parameters and constants: longwave emissivity for ocean, ice
215        and snow, evaporation parameters over ice
216      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
217        either wind from stress or stress from wind
218    o pkg/thSIce:
219    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
220    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
221       and THSICE_CALC_THICKN
222    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
223    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
224      to make debugging easier.
225    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
226    o pkg/bulk_force:
227      - clean-up comments and parameters ;
228      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
229    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
230      generate new output for test-experiment: aim.5l_cs.thSI
231    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
232      testreport accordingly
233    
234    checkpoint58e_post
235    o SEAICE_CGRID adjoint done
236    o R_STAR adjoint implemented.
237      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
238      * need to sort out init. of h0facc, etc.
239    o Make pkg/profile fully independent of ecco,cost, etc. stuff
240      to be able to use it in pure forward.
241    
242    checkpoint58d_post
243    o upgrade simple test-experiment to tutorial example:
244     step.1: duplicate the experiment and (step.2) will remove the old copy.
245      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
246      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
247      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
248      tutorial_global_oce_biogeo    <- copy of dic_example
249      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
250      tutorial_plume_on_slope       <- copy of plume_on_slope
251      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
252      tutorial_global_oce_optim     <- empty for now (David ?)
253      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
254     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
255    o correct a sign problem in cost_scat.F
256    o obcs and ptracers: fix boundary conditions for advections schemes
257      with larger stencil
258    o thsice adjoint: start
259    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
260      completeness
261    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
262      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
263    o ptracers adjoint:
264      * avoid extensive recomputatations
265      * fix missing re-init. of gptr (missed by TAF)
266    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
267      me to turn off the excessive output to STDOUT that this package produces
268    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
269      and add those terms in Vector-Invariant formulation.
270    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
271      if the control period (xx_hfluxperiod etc) is 0
272    o in profiles pkg, clean routines and fix details
273    o in ecco pkg, reading ssh data:
274      fix problem in case the model does not start at iter0=0
275    o fix mnc-pickup/restart for ptracers
276    o new package prifiles:
277      code to compute profile-based cost by Gael Forget
278      (modifs in ecco, ctrl, autodiff)
279    o Benign bug fix in initialization (spotted by M. Mazloff) of
280      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
281    
282    checkpoint58c_post
283    o adjoint: finish NLFS adjoint and provide reference output in
284      verification/global_ocean.90x40x15/results_ad_nlfs
285    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
286      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
287      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
288      with SEAICE_CGRID defined.
289    o move calendarDumps from "data" to "data.cal" and clean-up the code
290      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
291    o add useEXF & useCAL flags (for now, set in hard-coded way)
292    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
293      (were missing in NH mode, and wrong in quasihydrostatic mode).
294      waiting for Chris updated version of calc_gw to add those CALLs.
295    o fix bug in quasihydrostatic S/R ;
296      add a test for this option: global_ocean.90x40x15.qshyd
297    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
298      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
299    o add on/off flag useOffLine for package OFFLINE
300    o seaice:
301      - modify advection so that it works also on the C-grid
302      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
303        problem in multi-tile runs with C-grid
304      - add flags for clipping ice velocities and/or masking solver forcing
305      - fix drag (ocean on ice) formulation and a bug that caused noise in the
306        C-grid solver
307      - added a few comments to seaice_diffusion.F
308      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
309        are now exclusive)
310      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
311        required re-ordering the code a little:
312       + make DAIRN global variable (defined in SEAICE)
313       + move computation of the viscosities eta and zeta into a new separate
314         routine (because I need to recompute them in seaice_ocean_stress.F)
315    
316    checkpoint58b_post
317    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
318      update output.txt of exp. aim.5l_cs.thSI
319    o various mnc cleanups and improvements:
320      + shrink lookup tables by factor of ~4
321      + better error reporting when running out of lookup space
322      + able to handle longer path/file names (up to 500 chars)
323    o adjoint:
324      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
325      - TBD: "hidden" mom_vecinv recomp. in dynamics
326    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
327     (allow to differentiate between forcing components using new integer flags:
328      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
329     and add new flag to put Dissipation tendency out of Adams-Bashforth.
330    o ecco
331      - enable trend removal from SSH anomaly obs.
332    o adjoint
333      - a fix for PmEpR when #undef EXACT_CONSERV
334      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
335      - try to fix "hidden" recomp. in forward_step for NLFS
336        (NLFS seems broken sometimes after I checked it in)
337    o seaice:
338     - add c-grid version of the dynamic solver:
339       + three new routines that are the c-grid substitute lsr, dynsolver
340         and ostres
341       + put a few fields that were local to dynsolver into global common
342         blocks, so that I can move the computation of stresses etc into
343         seaice_lsr (saves coding but may break the adjoint).
344     - replace more hardwired parameters by runtime parameters
345     - add ice masks that mask the rhs of the implicit solvers where there
346       is no ice (commented out in seaice_dynsolver, because i am not sure
347       if this works properly), eventually this should replace the clipping
348       of ice velocities in seaice_dynsolver to +/-40cm/s.
349    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
350      include it only where its needed
351    o move balancing of fluxes before the call of external_forcing_surf
352    o seaice:
353      - correct units of turning angles (now they are really in degrees)
354      - move computation of GWATX/Y out of main routine into dynsolver
355      - initialize GWATX/Y in seaice_init
356    o Apply mask on Fresh-Water flux (needed for SSH forcing).
357      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
358    o seaice: add runtime flags for turning angles (default to zero)
359    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
360      and trend from exf forcing and ctrl control adjustments
361    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
362      (since checkpoint57x_post)
363    o change the default rotation period to 86164.s = the Earth rotation
364    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
365      and based on a reference stratification. Tested within hs94.cs-32x32x5.
366    o seaice advection: add code for choosing between the default (2nd order
367      central differences) and multiDim advection schemes provided by
368      pkg/generic_advdiff
369    o seaice:
370      - removed all references to SEAICE_GRID.h fields from
371        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
372        (cubed-sphere configuration will change a little)
373      - grid computations in seaice_init are obsolete now.
374      - cleaned up code a little so that is easier to read (hopefully).
375      - added new (better?) discretizations of default advection and diffusion
376        (turn on with SEAICEuseFluxForm)
377      - replace 1 in 3d global fields by kSurface in growth.F
378      
379    checkpoint58a_post
380    o seaice:
381      - bug fix in advect.F
382    o shelfice:
383      - separate shelfice load anomaly from pload (breaks with time
384        dependent forcing), => introduce constant field shelficeLoadAnomaly.
385        Its default is 0., but it may be computed more cleverly from (unknown)
386        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
387        done offline. A good approximation of the pressure load anomaly is
388        necessary to avoid large initial adjustment processes underneath
389        deep-reaching shelfice.
390      - small fix in ISOMIP shelfice_thermodynamics
391      - add more sophisticated thermodynamics of Hellmer (1989), this is
392        now the default
393      - give a few constants more intuitive names
394    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
395      if bulk formulae are used in long integration (especially EmPmR). Turn
396      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
397      if balancePrintMean, the imbalance that is substracted is printed to
398      STDOUT.
399    o fix bug (typo) in obcs_apply_eta.F
400    o add a new package shelfice which enables us to model the circulation
401      underneath shelf-ice with draughts of hundreds of meters.
402     - works
403     - to do: + include improved thermodynamics
404              + check whether kSurfC (from model/inc/SURFACE.h) can be used
405                instead of new field kTopC
406              + can we use topoFile, Ro_surf and existing code in ini_depth.F
407                instead of new field R_shelfIce and new code in ini_depth.F
408                and ini_mask_etc.F?
409              + adjust vertical mixing schemes?
410    o seaice pkg:
411     - add a cpp-flag to include a simple formula for a salinity dependent
412       freezing point of sea water at the surface
413     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
414       meridional stresses are now different (and hopefully correct)
415    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
416       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
417       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
418    o pkg/diagnostics: add options and parameters for regional-statistics
419       diagnostics ; define regions by reading a region-mask from a file
420       (might add other options later)
421    o pkg/bulk_force:
422     - add option and parameters to use AIM surface-flux formulae.
423     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
424       others forcing fields (defined in PARM05, parameter file "data") are loaded
425       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
426     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
427     - use the right EXCH call for uwind,vwind (to work on CS-grid).
428     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
429       and parameters (note: calcWindStress replaces .NOT.readwindstress).
430     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
431    
432    checkpoint58
433    o add "--embed-source" option to genmake2 which, when the supporting
434      tools can be compiled (as determined by genmake2) will turn on the
435      embed_files package which then embeds the entire MITgcm source code
436      (*.[fFhc] + Makefile) used for the build within the executable
437      - requested by CNH but off by default
438      - adds a paltry <9MB to the mitgcmuv executable in most cases
439      - only writes the output when useEMBEDSRC in eedata is true
440    o clean up 3-dim. relaxation codes:
441      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
442      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
443      * Thanks to Tom Haine for testing!
444    
445    checkpoint57z_post
446    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
447      affects output (@ truncation level) of exp. plume_on_slope ; updated.
448    o fix the pickup behavior for obcs in combination with ptracers
449    o fix a bug in ptracers_external_fields_load
450    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
451      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
452    o transfered surface NH pressure to eta field (if exactConserv).
453    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
454         and update lab_sea output.txt file.
455    o completing 3-dim. relaxation code: additional term
456         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
457      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
458      * At compile time, in "EXF_OPTIONS.h" set
459          #define  ALLOW_CLIMTEMP_RELAXATION
460          #define  ALLOW_CLIMSALT_RELAXATION
461      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
462          tauThetaClimRelax3Dim = 15552000.0,
463          tauSaltClimRelax3Dim  = 15552000.0,
464      * 3 cases:
465          1) Use a constant-in-time 3-dim. field
466          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
467          3) Real-time relax. to time-evolving prescribed field
468    o Adding Laplacian-type smoothness constraint on
469      initial and boundary (forcing) controls (ic, bc)
470      * enable at compile-time via
471        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
472      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
473      * Absolute scale somewhat unclear so far
474      * no area weighting was included since no other cost term does so far
475    
476    checkpoint57y_post
477    First step for a NLFS adjoint
478    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
479    o new init. routines for calc_r_star, calc_surf_dr
480    o still need to deal with ini_masks_etc
481    o testreport seemed happy
482    checkpoint57y_pre
483    
484    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
485    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
486    o add new offset feature to offline pkg (plus minor cleanup)
487    o cfc fixes for final year of integration
488    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
489      be in GCHEM_OPTIONS).
490    
491    checkpoint57x_post
492    o fix testreport Pb in multiple test experiment.
493    o cleanup our namelist syntax in verification:
494      - make it more F95 standards compliant (some work still needed)
495      - allows the vast majority of our tests to work with gfortran
496    o Non-Hydrostatic:
497     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
498     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
499    o Allow to apply AB on T,S rather than on AB(gT,gS):
500     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
501     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
502       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
503     - need a "clever" read_pickup to restart from the other AB formulation
504    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
505    o remove some unused variables (reduces number of compiler warnings)
506    o adjoint
507      * Disable useVariableViscosity for adjoint for time being
508        (there are a number of extensive recomputations)
509      * Initialize certain variables needed for adjoint
510    
511    checkpoint57w_post
512    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
513                 fix the singleCpuIO RS version of MDSWRITEFIELD
514       and add a WARNING if using globalFiles=T with multi-processors.
515    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
516      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
517    o tracer advection scheme:
518      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
519       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
520       was not very convenient).
521      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
522       (further tests needed for the implicit DST & Flux-Limiter schemes).
523    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
524      and sRef for convenience, handy, when you want to initialize
525      ptracers in a large domain with a constant non-zero value. Also,
526      untangle ptracers_init.F a little.
527    
528    checkpoint57v_post
529    o change dome exp. to use variable viscosity in side-drag terms.
530    o remove all the files from the cfc_offline test since they are now
531      incorporated into tutorial_cfc_offline which has been producing
532      identical results for a few days of testing
533    o add new parameter: sideDragFactor to enable half-slip-side BC
534      and change side-drag S/R to use viscosity from mom_calc_visc
535      (can switch back by setting sideDragFactor=0.); affects results at
536      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
537       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
538    o vorticity & strain are now computed without masking, to account for
539      no-slip-side BC in variable viscosity calculation ; mask is applied
540      anyway later on, before computing advection/coriolis terms.
541    o modify exp4 to test new obcs support for reading from external files
542      and for passive tracers
543    o fix behavior of ptracers_monitor when monitor output is written to a
544      netcdf-file; still not independent of monitor.F (writes in the same
545      file).
546    o change default value of tRef (put a uniform, meaningful value for ocean
547      & atmos) and initialize sRef (was missing, as Martin mentioned).
548    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
549      to be proportional to enstrophy dissipation length.  Thus,
550       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
551      This is now consistent with Smagorinsky and with the manual.
552    
553    checkpoint57u_post
554    o OBCS and PTRACERS: add open boundary support for passive tracers
555      - either use homogenous (pseudo) v.Neumann conditions or prescribe
556        OB-values from file; this is not different from the way theta and salinity
557        are treated
558      - however, Orlanski-radiation conditions are not supported, and the model
559        will stop if you use pTracers and Orlanski at the same time.
560      - beefed up the rountine obcs_external_fields_load: now only those open
561        boundary values are overwritten with values from files for which there
562        are really files, otherwise the OB-fields remain untouched. This makes
563        it possible to use different OBs at different ends of the domain (as
564        with EXF)
565    o reduce number of exch calls in shap_filt (s2).
566    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
567      truncation level) 4/5 MLAdjust test results (11&12 digits match).
568    
569    checkpoint57t_post
570    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
571    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
572      same truncation, independent of the face number: affects affects several
573      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
574    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
575      note that biharmonic viscosity + no-slip was not tested in any experiment.
576    o fix bug in non-linear free-surf side-drag ; generate new output for
577      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
578    o make mnc honor the writeBinaryPrec flag for most kinds of output
579    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
580    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
581      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
582    o add brackets in multi-terms sum to get same truncation, independent of
583      the face number (manage to get exactly same value of gU,gV at the cs-edge)
584      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
585    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
586      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
587      a maximum grid-scale Reynolds number.  Also, changes all length calculations
588      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
589      Suggested values of viscosity parameters found in mom_calc_visc.
590      Many new viscosity diagnostics available.
591    
592    checkpoint57s_post
593    o Add clearing-house for viscosity calculations, mom_calc_visc and
594      correct numerous bugs in LeithD and Smagorinsky discretizations.  
595      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
596      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
597      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
598      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
599      The Strain-Tension form is now called with useStrainTensonVisc=.true.
600      ViscAhStrain and viscAhTension are now retired.
601    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
602    o In response to JMC's bug report, genmake2 now ignores any soft-links
603      that it finds in the *current* directory when searching for files.
604      Soft-links found in any other source directories will still work as
605      they did before.
606    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
607      a C routine to unlimit the stack size
608    o mnc-ify pkg/aim snapshot vars
609    o mnc-ify pkg/land as requested by Daniel
610    o various changes to mnc including:
611      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
612      - output can now be grouped so that all files within a group
613          change the ITER portion of their names in lock-step together
614      - can now read ("global") PER-FACE (in addition to PER-TILE) files
615          and works with both EXCH1 and EXCH2 (but needs more testing)
616      - writing works for all verification test cases w/ g77 on Linux
617    
618    checkpoint57r_post
619    o make MNC variable initialization happen earlier
620    o add diagnostics for (almost) each term of the momentum Eq.
621    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
622    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
623    o remove MINIMAL_TAVE_OUTPUT option ;
624      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
625    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
626      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
627    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
628    o add time-dependent SST, SSS control
629    o cost terms in ecco/ modularized (new cost_generic.F)
630    o cost_averages routines are modularized (new cost_averagesgeneric.F)
631    o new infrastructure for seaice model vs. obs misfits in seaice/
632      * driver from the_main_loop.F is seaice_cost_driver.F
633      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
634      * gradient check in Exp. 6a of natl_box_adjoint/
635    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
636      (see README file)
637    
638    checkpoint57q_post
639    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
640    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
641      - bug was reported by Jean-Michel and Ian Fenty
642    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
643      update exp. cpl_aim+ocn output.
644    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
645      Needed for high-res. runs with large global files
646      to be able to limit tapelev size
647    o Changed some tests for adjoint:
648      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
649      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
650      * global_ocean.90x40x15/ back to default 3-level checkpointing
651    o Modifications to enable scripted COMMON to MODULE conversion
652      * verification/OpenAD/code/ has necessary scripts and description;
653      * converts, compiles and runs successfully;
654    
655    checkpoint57p_post
656    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
657    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
658      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
659    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
660    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
661      (was already the case for dissipation with mom_vecinv,
662       and also the case for grad.PhiHyd when staggered-timeStep)
663      This will allow to put dissipation out-off the AB time-stepping.
664     Unfortunately, affects truncation error. Update output of exp. that "fails"
665      (cg2d matching number) and leave the others for later: front_relax(10),
666      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
667      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
668    
669    checkpoint57o_post
670    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
671      (2) its ready to be documented during the 20050801 DocFest
672    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
673      for ideal_2D_oce and lab_sea on linux_ia32_g77
674    o set to #undef CTRL_SET_OLD_MAXCVARS_30
675      in global1x1_tot/code_seaice_adj to access indices 32, 33
676      (worth another tag)
677    
678    checkpoint57n_post
679    o adding precip control xx_precip 32
680    o adding swflux control xx_swflux 33
681    o Replacing 10 forcing penalty cost routines by 1 generic.
682    o Implementing partitioning in time-mean and variable adjustment
683      for atmos. state.
684    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
685    o in natl_box_adjoint:
686      * updated exp 1 to 10
687        (but does not have time-mean vs. variable split results yet)
688    o updated global1x1/*_seaice_adj/
689      to incorporate latest changes
690    o enable useSingleCpuIO for mdsio vector routines
691      (applies in particular to tapelev I/O)
692    o removed inefficient K-loop in all active_file*control*.F
693    
694    checkpoint57m_post
695    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
696      and advect_cs (use EXCH-2 and standard cs-32 grid files).
697    o pkg/exch2: filling of face-corner halo regions is optional
698      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
699    
700    checkpoint57l_post
701     tag before updating tutorials (pre-release-2)
702    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
703       for output and interpolation of input fields onto model grid)
704    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
705       Affects results of exp. rotating_tank ; update output.txt.
706    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
707          and taking the square quantity and/or using a fraction-weight field.
708    o fix aim_diagnostics_init.F mate numbers.
709    o add mnc output capability to diagnostics/diagstat and update
710      our cvsignore files for the ACSII output generated
711    
712    checkpoint57k_post
713    o lab_sea now uses diagnostics package and provides a suite of
714      new EXF diagnostics output.
715    
716    checkpoint57j_post
717    o exf
718      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
719        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
720        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
721      * extended diagnostics output
722        - now includes all EXF variables
723        - hs, hl moved to common block
724        - separate S/R for diagnostics, called after ctrl vector is added
725        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
726        - EXFqnet contains true Qnet (i.e. includes qsw)
727      * updated verif. lab_sea, global_with_exf
728      * Rearranging hflux (exf_mapfields -> exf_getforcing)
729        to ensure that diagnostics sees a true EXFqnet
730    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
731    o diagnostics pkg: change pointers so that 1 diagnostic can be used
732      several times with different frequencies.
733    o mnc-ify the thsice package as requested by Daniel Enderton
734      - the monitor--MNC output needs work
735      - many attributes need to be added (most are currently blank)
736    o mnc-ify theaim_v23 package as requested by Daniel Enderton
737      - many attributes need to be added (most are currently blank)
738    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
739    o add Sadourny like discretization to the 4th.O vorticity advection scheme
740    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
741      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
742         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
743    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
744     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
745    
746    checkpoint57i_post
747    o Diagnostics package was changed: diagnostic allocation is now deactivated
748      by setting an empty file name in the namelist (used to be by setting 0 frequency)
749    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
750      add 1rst Order upwind vertical Shear.
751    o add a quick fix for A/B checkpointing in OFFLINE mode
752    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
753      end-run around the C/Fortran linking horror in eesup/src/timers.F
754    o added pkg/runclock: allows user to terminate run based on wall clock
755    o added non-hydrostatic scaling parameter: nh_am2
756    o pkg/my82: futile attempt to make results compiler-independent by adding
757      some "_d 0", etc. no effect.
758    o for mnc output, fill the 'T' coordinate var with myTime and create a
759      separate 'iter' variable for iteration count
760    o pkg/diagnostics:
761      add new capability: output of Global/Regional & per-level statistics ;
762      tested against monitor output (including land & thSIce) on various exp.
763    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
764    
765    checkpoint57h_done
766      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
767      data.diagnostics, data.gchem, data.ptracers) is done.
768    
769    o pkg/diagnostics: prepare for Global/Regional statistics.
770      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
771    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
772      and rename it: DIFFERENT_MULTIPLE
773    
774    checkpoint57h_post
775    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
776    o pkg/diagnostics: change output frequency, now in seconds (instead
777      of Nb of iterations). This requires to change data.diagnostics.
778    checkpoint57h_pre
779    
780    o in mnc, let the user create the output dir if both mnc_outdir_date
781      and mnc_outdir_num are false
782    o add fflags() to pkg/diagnostics which allows one to specify, on a
783      per-file basis, the file precision [default behavior is unchanged]
784    o added diagnostics to pkg/kpp, including computation of mixed layer
785      depth based on a temperature/density criterion
786    o updated verification/natl_box to test the new pkg/kpp diagnostics
787    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
788    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
789    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
790      not mnc -- this mistake was found by JMC and is now corrected
791    
792    checkpoint57g_post
793    o add Adams-Bashforth 3rd Order time stepping:
794      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
795      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
796    checkpoint57g_pre
797    
798    o make lambda[Theta,Salt]ClimRelax spatially varying
799      (default remains spatially uniform constant based on tau)
800    o added new control variables
801      * init. uVel, vVel, etanN
802      * lambda[Theta,Salt]ClimRelax
803    o separate masks used for ctrl_pack/unpack 'from write_grid' output
804      (suggested by G. Forget)
805    
806    checkpoint57f_post
807    o add parameter "baseTime" = model base time = time at iteration zero
808      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
809      account for baseTime shift
810    o move Coriolis arrays from PARAMS.h to GRID.h
811    checkpoint57f_pre
812    
813    o mnc-ifying the seaice package
814    o introduced an alternative length scale calculation for use in the limiting
815      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
816    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
817    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
818      as well as grad(vort3).  Made it compatible with both approximate form
819      for the cubed sphere and full form of these gradients.  Added flag
820      useFullLeith to select between approximate and full form.  
821    o add "d0" in getcon.F to reduce differences between compilers/platforms
822      update output.txt of exp. fizhi-gridalt-hs
823    o change port_rand funtion to allow to set the seed.
824    o fix obscure MNC bug involving conversion between reals and integers
825      - it caused no problems with certain (eg. gcc, ifc) compilers but the
826        new version is now more standards-compliant
827    o adjoint-related modifications
828      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
829      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
830      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
831    
832    checkpoint57e_post
833    o Adding eddy stress controls a la Ferreira et al.
834    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
835    
836    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
837      update output.txt of exp. fizhi-gridalt-hs
838    o add more "Z" dimensions and associated coordinate vars to MNC
839    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
840    o parameter calendarDumps: when set, approximate months (30-31 days) and years
841      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
842      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
843      months and years.  Requires pkg/cal.
844    o diagnostics: add pickup functionality
845      - off by default for backwards compatibility
846      - current version only uses MDSIO -- MNC will be added
847    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
848    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
849    
850    checkpoint57d_post
851    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
852    o modify verification/ideal_2D_oce so that it tests the creation of mnc
853      output from the diagnostics package
854    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
855    o make genmake2 more portable by using ".$FS" instead of ".f" for more
856      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
857    o add coordinate variables to the MNC output from the diagnostics package
858    o change MNC-flags default value: true when useMNC=TRUE
859    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
860      the ability (off by default) to read the grid information using MNC
861    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
862    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
863    o do snap-shot diagnostics at the middle of the time-interval (instead of
864      at the end).
865    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
866      new test for AIM with thSIce + slab-ocean
867    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
868    o move state variable diagnostics to the beginning of the time step ;
869      (note: still needs some work specially for snap-shot diagnostics)
870      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
871    
872    checkpoint57c_post
873    o Change testing option (-ieee) to get closer agreement between g77 & ifort
874    o generate new output.txt files on faulks with g77 & the new -ieee option
875    checkpoint57c_pre
876    
877    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
878      update output.txt of exp. global_ocean.90x40x15
879    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
880      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
881    o add saltFlux(+File) forcing capability with periodicExternalForcing
882    o allow to use pkg diagnostics for GM-Redi & ThSIce output
883    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
884    o improvements for the MNC output from DIAGNOSTICS:
885      - correct handling of the unlimitied dimension
886      - all dims now have associated coordinate variables
887      - variables located at U, V, and Corner ("Z") points are now written
888        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
889        *all* data points are output
890    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
891    o added pkg/seaice/seaice_monitor.F
892    o mdsio_readfield.F can now read files visible only to master MPI process.
893    o pkg/seaice: some test code for ice-modified ocean stress
894    o exf_getffields interpolation defaults to bilinear for all scalar forcing
895      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
896      spurious negative numbers for precipitation and humidity.  Will cause
897      some small numerical differences for integrations using pkg/exf/exf_interp.F.
898    o pkg/ctrl/
899      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
900        May be enabled via doPackDiag
901      *  introduce z-scaling of
902         + gradient (doZscalePack) and
903         + control (doZscaleUnpack)
904    o pkg/mdsio/
905      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
906      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
907    
908    checkpoint57b_post
909    o simplify options in diagnostics_fill arguments (remove weird combinations)
910    o fix MNC coordinate variables so that they now contain per-face index
911      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
912      general, EXCH2 grids are only aligned to a "local" coordinate system
913    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
914    o Implement instantaneous output within pkg diagnostics:
915      setting a negative frequency in data.diagnostics produces
916     "snap-shot" output (as opposed to time-average if freq > 0)
917    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
918      NOTE: change ptracer diagnostics name: use 2 characters to work with
919            more than 9 tracers. Add also diagnostics of advect & diffus flux.
920    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
921      becomes the coordinate variable for the 'T' dimension
922    o add CF-style coordinate variables to MNC
923      - just a first cut:  numbers are meaningless on the cubesphere and
924        missing along the T axis but otherwise it works!
925    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
926    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
927    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
928      this is based directly on what the model compute, so that the content of
929      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
930    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
931    o clean up build options files for SunOS, in particular
932      - remove -traditional from xmakedepend
933      - change -xarch=v9 to -xarch=native for f77
934      - restore use of make (not gmake)
935      - add CC=gcc if using g77
936    o changes per discussion of AM, JMC, & EH3 today:
937      - move redundant "grid" variables out of "state" -- in preparation of
938        creating proper CF-style coordinate variables and in recognition
939        that any/all grid variables can be easily copied (eg. w/NCO) from
940        the grid files into any of the other NetCDF files
941      - *always* output grid variables with MDSIO (this will eventually be
942        changed)
943      - output MNC grid file if useMNC is true
944    o every instance of _END_MASTER() has been found and replaced with
945      _END_MASTER( myThid ) in order to satisfy certain picky Sun
946      preprocessors
947    o re-arrange diagnostics pkg initialisation:
948     - allow each package to extend the available diagnostics list
949     - add some checking and fix small problems (multi-threaded, ...)
950     - new S/R diagnostics_fill (replace fill_diagnostics):
951       look through the short list of active diag. (instead of the long list)
952       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
953    
954    checkpoint57a_post
955    o this set of changes restores TAMC compatibility
956      tested for global_ocean.90x40x15 adjoint on trough
957      (what a pain)
958    
959    checkpoint57a_pre
960    o some modifs in tools/build_options for sunos
961    o call ctrl_pack for ctrl at end for optimcycle=0
962    
963    checkpoint57
964    o add horizontal bi-harmonic viscosity for vertical velocity
965      - new parameter viscA4W (defaults to viscA4)
966      - affects only non-hydrostatic code
967      - to be done: no-slip lateral boundary conditions
968    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
969    o implement Implicit Vertical advection for pTracers
970    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
971      (implemented also for implicit vertical diffusion & advection)
972    o OBCS: extend application of tracer open boundary conditions
973      to a strip beyond the boundary of width Olx/Oly
974    o add call monitor to TAF set of required calls (flow directives)
975      and include in natl_box_adjoint
976    o untangle a few ifdefs related to cost, ctrl, autodiff
977      untangel a few ALLOW_ECCO_OPTIMIZATION
978    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
979      (theta2, salt2 in ecco_cost_weights)
980    
981    checkpoint56c_post
982    o OBCS as control variables
983      - update ctrl_ad_diff.list, obcs_ad_diff.list
984      - remove balance of obcs controls from default
985      - fix index bug nobcs in ctrl_init
986      - fix dummy fields filen in ctrl_pack
987      - add dummy weights for obcs
988    o lsopt: comment out fort.94 output
989    o optim:
990      - remove unnecessary header files
991      - adjusted namelists
992      - add xerbla.F to Makefile
993    o exf:
994      - multiple modifications of exf_check_range
995      - unit change in exf_init_runoff from [m/year] to [m/s]
996    o mdsio:
997      - i/o-vector change debugLevel from debLevA to debLevB
998    
999    checkpoint56b_post
1000    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1001      is called from DO_THE_MODEL_IO
1002      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1003      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1004      - clean up PTRACERS_WRITE_TIMEAVE a little
1005    o add another verification experiment that tests both the cfc-pkg and
1006      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1007      reactive tendencies treated inline with regular timestepping
1008    o testreport previously did a lousy job of comparing small numbers, so
1009      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1010      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1011      testreport.
1012    o ptracers_monitor: bug fix for MPI
1013    
1014    checkpoint56a_post
1015    o GCHEM: finish reorganizating the package
1016      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1017        (introduces another 3D-array for each passive tracer, but only if
1018        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1019        gchemTendency is not needed because the timestep is done separately)
1020      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1021      - GCHEM is now---more or less cleanly---separate from PTRACERS
1022      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1023        so clear to me how that should be done in a general way.
1024    o CFC: improve formatting of output in CFC_ATMOS
1025    o PTRACERS:
1026      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1027        that ALL experiments with ptracers enable can be checked. This makes
1028        GCHEM_MONITOR obsolete.
1029      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1030        monitorFreq
1031      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1032    o add PTRACERS (PTR0[1-5]) to testreport output
1033    o exf_check_range:
1034      * default changed to .TRUE.
1035      * will check values for niter0 if debLevA, every timestep if debLevB
1036      * STOP in exf_check_range if 'out of range'
1037      * range chosen generous to allow for potential extema
1038      TBD: a version with stricter range
1039           permitted range would be runtime parameters
1040    o GMredi:
1041      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1042      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
1043      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
1044    o GCHEM:
1045      - move call to GCHEM_FORCING_SEP, so that it is now called before
1046        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
1047      - introduced a useGCHEM runtime flag and applied it everywhere.
1048      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1049        this flag is now only visible within GCHEM-pkg routines.
1050      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1051        be replaced by a 3D array that is computed before thermodynamics; for
1052        this, the tracer ID iTracer had to be included into the parameter list
1053        of ptracers_forcing
1054      - set up forward_step to call gchem_forcing, that will replace
1055        gchem_forcing_int in ptracers_forcing
1056      - cleaning up
1057    o small cleaning of exch2: remove files that are also in eesupp/src
1058    
1059    checkpoint56
1060    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
1061    o mnc: cleanup "full" files--fixes out-of-memory problem
1062    o ECCO-GODAE
1063      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
1064      * fully merged and updated from SIO code
1065        windstress sign change affects
1066        - exf_inscal_[u/v]stress
1067        - sign of xx_tau[u/v] adjustments
1068        - signs in cost_scat
1069      * ctrl_get_gen: avoid update of tau[u/v] for first few days
1070      * natl_box_adjoint updated and compressed
1071      * 2-level checkpoint switch added
1072        (tested in EXP. 1 of natl_box_adjoint)
1073      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
1074    o SVD
1075      * first complete, non-hacked version for SVD calculations
1076      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
1077        performed via direct access files admtlm_vector.it????
1078        (via ctrl_[un]pack)
1079      * optimcycle is used for ARPACK iteration counter
1080        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
1081      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
1082        and add linear transforms where necessary
1083      * controls are initial/final SST, SSS (can be extended; need to check
1084        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
1085    o mdsio: filename info to both stderr, stdout
1086    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
1087      from sign change
1088    
1089    checkpoint55j_post
1090    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
1091      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1092    o add consistent build directories and .cvsignore files to verification
1093    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
1094    o make all subroutines 30 or less characters in length for certain older
1095      compilers to work (a thorough search only turns up two routines in
1096      pkg/ptracers)
1097    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
1098      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1099    
1100    checkpoint55i_post
1101    o change arrays for total vertical diffusivity (2.D if explicit,
1102      3.D if implicit) ; each ptracer uses its own background value.
1103    o added mnc/NetCDF output capability to ocn_compon_interf
1104      - added bits to verification/cpl_aim+ocn so that it can run on
1105        ITRDA and other clusters without the mpirun "-wd" option
1106    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
1107      configuration
1108    o give MNC the ability to create additional files rather than
1109      exceeding a specified file size limit "MNC_MAX_FILESIZE"
1110      - the default is just less than 2GB which is a practical limit
1111        on many systems
1112    o Compute the non-local term using either KPP vertical diffusivity (=default)
1113       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
1114    
1115    checkpoint55h_post
1116    o add verification test "vermix"
1117    o remove all the *_ioinc flags and replace with the single global
1118      outputTypesInclusive flag
1119    o allow to set a vertical profile of vertical diffusivity for T & S
1120    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
1121    o useMNC moved from data.mnc to data.pkg
1122    
1123    checkpoint55g_post
1124    o Renaming carbon AD experiments to comply with testreport conventions
1125    o Updating adjoint of Held-Suarez hs94.1x64x5
1126    o Fixing directives for non-ECCO forward_step, after ECCO directives
1127      have been fixed to avoid recomp. of do_oceanic_phys
1128      Works well for global_ocean.90x40x15,
1129      but recomp. issue remains for carbon
1130    o Updating adjoint output for natl_box_adjoint after
1131      pkg/ecco has been modified (see taga c55d_post)
1132    
1133    checkpoint55f_post
1134    o rename to timeave_init_fixed
1135    
1136    checkpoint55e_post
1137    o some delicate re-shuffle of store directives to avoid one
1138      extra call of do_oceanic_physics
1139      affects ecco_the_main_loop.F, do_oceanic_physics.F
1140      checkpoint_lev1_directives.h
1141    o NB: this may break global_ocean adjoint temporarily,
1142      but it is clear how to fix it. Will do later, need this now.
1143    
1144    checkpoint55d_post
1145    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1146    o ecco_cost_weights is modified to 1x1 runs
1147    o modifs to allow observations to be read in as
1148      single file or yearly files
1149    o enable to read exf forcing fields as either
1150      single file or yearly files (flag useExfYearlyFields)
1151    checkpoint55d_pre
1152    
1153    o switch between 2-level and 3-level checkpointing
1154    o add ability of MNC to write local and "partial" (eg. 2D slices where
1155      the full 3D field is never actually stored) arrays to NetCDF files
1156      with the correct (that is, the complete multi-dimensional) set of
1157      array indicies
1158      - used in mom_vecinv() to write the diagFreq output
1159      - tested (demonstrated) in verification/aim.5l_cs
1160    o further mnc-ification
1161      - add verification/lab_sea to the list with mnc setups
1162      - fix undefined mnc v-names in cd_code
1163      - add kpp to mnc output (both snapshot and timeave)
1164    o non-hydrostatic code
1165      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1166        in calc_gw.F
1167      - defaults to viscAh
1168      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1169        friction or Leith) in non-hydrostatic mode, as long as there is
1170        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1171    o pkg/cost
1172      extend simple cost functions to treat time mean quantities
1173      (T,U,V) via cost_accumulate_state from cost_tile
1174    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1175        be 2 times larger than the minimum size the advection scheme requires.
1176        now get a perfect conservation of salt in advect_cs test-exp (updated)
1177    o GGL90 (Gaspar's TKE mixed layer)
1178      - add horizontal diffusion of TKE, requires exchanges in
1179        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1180        default. In OPA there is no horizontal diffusion of TKE but the
1181        mixing coefficients are computed from a horizontal average of TKE of
1182        6 points or so. I think that diffusion has a little more physical
1183        justification.
1184      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1185        was in vain)
1186      - mask tke-variable in ggl90_init
1187    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1188    o fix biharmonic diffusion on CS-grid.
1189    o more obcs stuff
1190      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1191        for reading boundary values. This routine is called from
1192        obcs_prescribe_read
1193      - updated obcs_check
1194      - changed sponge layer relaxation parameter units for days to seconds
1195      - turned off sponge layer by default
1196      - changed argument list of OBCS_CALC to myTime+deltaTclock
1197      - fixed about 35 bugs in obcs_external_fields_load
1198    
1199    checkpoint55c_post
1200    o obcs stuff
1201      - new runtime flags useOBCSprescribe, useOBCSbalance
1202      - re-arranged obcs_calc
1203      - moved exf_getobcs to obcs_prescibe_read
1204        obcs_prescibe_read is called after ORLANSKI stuff
1205        and independent of it (executable can contain all).
1206      - updated obcs_check
1207      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1208        These may be necessary only if tangential velocities are
1209        prescribed at OB, not sure, needs testing.
1210    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1211      which simplifies the calls and passes the ifc check-bounds test
1212    
1213    checkpoint55b_post
1214    o add a 2D scalar, Z location, exchange_2 routine.
1215    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1216      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1217      affects advect_cs results (for the wrong reason): update output.txt
1218    o use a more standard discretization for biharmonic viscosity ;
1219     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1220      affects results of dome set-up: update output.txt
1221    o fix gad_advection.F (CubedSphere part), back to version 1.23
1222    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1223    
1224    checkpoint55a_post
1225    o merged code to
1226      * prescribe/read time-dependent open boundaries
1227        (works in conjunction with exf, cal)
1228      * sponge layer code for open boundaries
1229      * each boundary N/S/E/W now has its own CPP option
1230        (healthy for the adjoint)
1231    
1232    checkpoint55
1233    o up-to-date adjoint of previous breaks
1234      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1235      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1236      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1237      - carbon: * remove tr1-related adjoint verification
1238                * add ptracer as control variable
1239    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1240      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1241    
1242    checkpoint54f_post
1243    o in verification/carbin/ remove experiment related to
1244      ALLOW_PASSIVE_TRACER (array tr1 etc)
1245      code_ad/ input_ad/ results_ad
1246    
1247    o add two new packages
1248      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1249        + subject to optimization (memory)
1250      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1251        + subject to reordering (many GOTOs in the original code)
1252        + so far opps is called for every (i,j) point, and then operates in
1253          the vertical; one may want to reorder the scheme in order operate in
1254          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1255          fields)
1256    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1257      - all verification tests compile and run with linux_ia32_g77
1258      - defaults are compatible with current input files--nothing
1259        should change if you were not previously using MNC
1260      - MNC output has been added in numerous places (eg. timeave)
1261        but there are still a few writes not yet do-able with MNC
1262        (this is in progress)
1263      - flags now allow for either/or/both use of MDSIO and MNC and
1264        documentation will soon follow
1265      - numerous small formatting cleanups for ProTeX
1266    o add version info (via BUILD_INFO.h) to MNC and stdout
1267    
1268    checkpoint54e_post
1269    o add two new packages
1270      - pp81 (Packanowski and Philander, 1981), Richardson number and
1271        stratification dependent mixing
1272      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1273      - these scheme operate in a similar manner as KPP (without ghat, of
1274        course), however there is only one diffusivity that is used for both
1275        temperature and salinity (and passive tracers)ç
1276    o add offline package
1277    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1278      provided by Stephanie Dutkiewicz
1279    o genmake2: add ability to search for C compilers and cleanup test output
1280      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1281    
1282    checkpoint54d_post
1283    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1284    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1285      leading to additional shift by 5 days each year of integration
1286       (i.e. leading to considerable offset over the years)
1287    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1288    o start with no AB and no initial filtering (staggerTimeStep):
1289      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1290    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1291      (external loading & cpl import/export stay in forward_step.F)
1292    o update coupling interface to work with new staggerTimeStep
1293    o change MDSIO ptracers_pickup.
1294    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1295    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1296    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1297    
1298    checkpoint54c_post
1299    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1300      this affects (truncation error) output.txt of test-exp:
1301       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1302    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1303    o change Qnet to always be the net heat flux, (+upward).
1304      affects (truncation error) output of natl_box exp.: updated
1305    o define the max number of passive tracers in PTRACERS_SIZE.h
1306    o start to test mnc routinely in exp0
1307    o add sea-ice loading (sIceLoad) as a new forcing field.
1308    
1309    checkpoint54b_post
1310    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1311       impressive on Altix and Opteron systems)
1312    o diagnostics can now write NetCDF files through the mnc package
1313    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1314    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1315    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1316      affects (truncation error) output of lab_sea & natl_box exp.: updated
1317    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1318    
1319    checkpoint54a_post
1320    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1321    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1322    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1323    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1324      + internal_wave (shift in writing cg2d_ini_res)
1325    checkpoint54a_pre
1326    
1327    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1328      - modified verification/lab_sea and natl_box_adjoint accordingly
1329    
1330    checkpoint54
1331    checkpoint53g_post
1332    o prepare splitting of thermodynamics: store convect.counter in common block
1333    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1334      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1335    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1336    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1337    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1338    o restore adjointability
1339    
1340    checkpoint53f_post
1341    o modifications that affect AIM experiment results (update output.txt):
1342      - no advection of S at top interface Nr (pkg/generic_advdiff)
1343      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1344    o AIM pkg:
1345      - include stability function into surf.Flux derivative relative to Tsurf
1346      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1347    
1348    checkpoint53e_post
1349    o merged cylindrical coord configuration
1350    o added rotating_tank experiment
1351    checkpoint53e_pre
1352    
1353    checkpoint53d_post
1354    o faulks upgraded: re-generate output.txt that have changed:
1355       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1356    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1357    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1358    o added Sadourny discretization of Coriolis
1359      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1360      - re-enabled use of omega3 (useAbsVorticity)
1361    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1362      vector-invariant equations
1363      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1364    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1365      hopefully without new bugs
1366      - still to do: biharmonic friction for non-hydrostatic w
1367    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1368    o regenerated output for global_ocean_ebm (using -ieee)
1369    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1370      of mom_common/
1371      - simple re-arrangement of instructions within computing loop
1372    checkpoint53d_pre
1373    
1374    checkpoint53c_post
1375    o new version of coupler for AIM+thSIce and Ocean models
1376     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1377     - land: change Evaporation of snow
1378     - aim with thSIce: fix bug in snow-precip.
1379    o changes to calc_gw.F
1380     - bug fix for w^2 term near the bottom boundary
1381     - (hopefully) improve the lateral slip boundary condtions for use with
1382        partial/looped cells
1383      - because the bug fix changes two verification experiments anyway (exp5
1384        and plume on slope), change the lateral boundary condition from half slip
1385        to the value of no_slip_sides
1386    o ebm package wasnt quite up to the parallel task. Fixed that.
1387    o Adjoint of EBM package + verification
1388      * TLM OK
1389      * ADM not sufficient accuracy yet (needs further testing)
1390    
1391    checkpoint53b_post
1392    o Commiting new energy balance model to repository
1393      * package is pkg/ebm
1394      * verif. is verification/global_ocean_ebm
1395      * references are in ebm_driver.F
1396    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1397    C        Global thermohaline circulation. Part I:
1398    C        Sensitivity to atmospheric moisture transport.
1399    C        J. Climate 12(1), 71-82
1400    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1401    C        Global thermohaline circulation. Part II:
1402    C        Sensitivity with interactive transport.
1403    C        J. Climate 12(1), 83-91
1404    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1405    C        Destabilization of the thermohaline circulation
1406    C        by atmospheric eddy transports.
1407    C        J. Climate 7(12), 1870-1882
1408    o Will need long integration testing.
1409    checkpoint53b_pre
1410    
1411    o created pkg/mom_common in preparation for variable viscosity code
1412    o renamed and split ini_mnc_io
1413    o pkg/land: only liquid water can diffuse or run-off
1414    o AIM using land: soil wetness availability account for snow
1415    o added printMapIncludesZeros to EEPARMS namelist
1416    
1417    checkpoint53a_post
1418    o restore TAMC compatiility for exf_constants.h
1419      (no usage of _d in .h)
1420    o Additional storing in KPP in an attempt to fix
1421      TAMC problem with adjoint of KPP code.
1422      (no success...)
1423      Identical code works fine with TAF.
1424    o Fixed verification/natl_box_adjoint experiments.
1425      Initial conditions for Experiments 4 and 5 are now
1426      set to "SEAICE_initialHEFF=0", which is more reasonable,
1427      and hence gives results closer to that of Experiment 2.
1428      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1429    
1430    checkpoint53
1431    o stable checkpoint with up to date adjoint
1432      TLM tests only run for 1st grdchk at the moment. Its unclear if
1433      this is a code problem or a problem with resetting code for g_
1434      variables that is being autogenerated wrong.
1435      Otherwise:
1436       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1437       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1438         are both still in chaos following their security messes.
1439    
1440    checkpoint52n_post
1441    o various build (mostly genmake2) changes including:
1442      - ability to build/run more easily within Cygwin and MacOS X
1443      - more complicated Makefiles with a stronger dependence on Gnu Make
1444    o pkg/seaice modifications
1445      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1446        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1447        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1448      - changed proxy for geostrophic velocity and updated
1449        verification/lab_sea/results/* accordingly
1450      - removed ADI dynamic solver from pkg/seaice
1451      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1452        they caused a segmentation fault under certain circumstances
1453      - removed unused field WATR
1454    o bug fix in exf-package:
1455      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1456         now reflect that.
1457    o small fixes in the cal-package:
1458      - set reference date to first of January for the 'model'-calendar
1459      - failing of cal_CheckDate in cal_FullDate now actually results in a
1460        warning
1461    o small modifications in exf-package to increase flexibility:
1462      - change climtempfreeze from a constant to a runtime parameter that
1463        is specified in data.exf_clim (default = -1.9)
1464      - introduce runtime parameter windstressmax (default = 2.0) that is
1465        specified in data.exf
1466    o fix in pkg/thsice:
1467      - update Evap (Tsf changes) to be consistent with Latent heat flux
1468      - maintain snow precipitation unchanged (even if Tsf >=0).
1469     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1470    
1471    checkpoint52m_post
1472    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1473      this does not change any of the results, because myIter=0 in swfrac always
1474      lead to jwtype=2 (the default anyway), but the call makes little sense
1475      as a default
1476    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1477    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1478      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1479    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1480    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1481    o extending useSingleCpuIO option to work with new exch2 I/O format
1482      - old-style, missing-tile I/O is still accessible by defining CPP
1483        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1484    o monitor package can write to NetCDF files and/or STDOUT
1485    o fix re-definition bug in MNC_GRID_INIT_ALL()
1486    o doc/api_reference added
1487      - a framework for building an API Reference Manual using all
1488        the "protex" comments embedded in the code
1489      - see pkg/generic_advdiff, pkg/mnc for examples
1490    o MNC:
1491      - make myThid the last argument for all subroutines
1492      - new default for the grid files: NO halos
1493      - add useMNC and other run-time flags
1494      - separate per-file-group handling of the unlimited dimension
1495      - early initialization of MNC w/ flags read at the eeboot stage
1496        and lookup tables set in initialize_fixed
1497      - write all MNC output to a freshly-created directory
1498    o thermodynamics sea-ice (thsice) is now tested with testreport.
1499    o test exp. advect_cs: use the standard cs32 grid ; update output.
1500    o Added functionality to grdchk:
1501      pick global i,j,k position (or nearest wet) where to perform check.
1502    
1503    checkpoint52l_post
1504    o new land formulation:
1505      a) use ground enthalpy as prognostic variable to ensure exact
1506         energy conservation.
1507      b) account for water temperature and for latent heat of freezing
1508         in all processes (rain, run-off, ground storage)
1509      c) compute surface and ground temperature implicitly.
1510    o aim_v23 modification for new land model:
1511      a) Treat separately land / ocean / sea-ice surface fluxes
1512         to allow implicit computation of land & sea-ice surface temp.
1513      b) add snow precipitation.
1514    checkpoint52l_pre
1515    
1516    o fix problem (when 1 tile is empty) in min/max monitor.
1517    o fix bug in timeAve (u,vZetatave in common block)
1518    o no restoring terms under ice for pkg/seaice

1525    o exf: Adding simple range check routine for exf fields after read
1526    
1527    checkpoint52k_post
1528    o removed top-level directory "diags"
1529      - we migrated these functions to pkg/timeave a long time ago
1530    o fixed bug introduced in pkg/monitor
1531    o accuracy ctrlprec = 32 insuffient for gradient checks using
1532      averaged fields (I/O via cost_averages)
1533      -> use ctrl.h in active_file*.F to control I/O precision.
1534    o paramter list of CALL ADTHE_MAIN_LOOP
1535    o added initial do_the_model_io to ecco
1536    o set all ...Freq to zero after cost_final
1537      taveFreq, dumpFreq, pChkptFreq
1538    o MAIN and ECCO differentiability restored
1539    
1540    checkpoint52j_post
1541    o fix nchklev in tamc.h for global_ocean...
1542    o Bringing flow and store directives up-to-date
1543    o Really weird thing!
1544      call do_the_model_io from the_main_loop with parameters
1545      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1546      TAF places a faulty re-call of initialise_varia
1547      after cost_final call which should not be there!
1548    checkpoint52j_pre
1549    
1550    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1551      error messages
1552    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1553    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating

1558    o update AIM Equatorial Channel exp:
1559      use standard aim_v23 pkg and change the SST fields to be more realistic.
1560    o globalFile now works with exch2
1561    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1562      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1563    o limit timeave output for hi-res integrations
1564    
1565    checkpoint52i_post

1568    checkpoint52i_pre
1569    
1570    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of

1589    
1590    checkpoint52e_post
1591    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1592      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1593    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
