5      ==============================      ==============================
6    
7    o seaice advection with pkg/thsice: a step toward the use of non-linear
8      advection scheme, but #ifdef or commented out for now (requires more EXCH).
9    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
10      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
11      in natl_box (affects results @ truncation level: update output.txt)
12    o multi-threading and IO:
13      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
14      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
15        (needed to work with SingleCpuIO): tested in all verif. exp.
16    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
17      affects the results (but none of the verification test uses this scheme).
18    o Adding some pkg/diagnostics capability to pkg/seaice
19      (will certainly be subject to changes)
20    o ctrl: adding new control variables:
21      lwflux, lwdown, evap, snowprecip, apressure, runoff
22    
23    checkpoint58q_post
24    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
25      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
26      high_res_cube configuration by 4% on Columbia.
27    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
28      add (in global_with_exf/code) a version of EXF_INTERP_READ without
29      dynamical allocation (seems to work in multi-threaded).
30    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
31      single CPU io) so that TAF does not have to see EESUPPORT.h
32    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
33    
34    checkpoint58p_post
35    o obcs: stop if obcs is used with useCDscheme = .true.
36    o shelfice:
37     - fix a sign error so that no slip at shelfice interface works
38     - remove stop for combination non-hydrostatic code and shelfice. That does
39       not mean, that the results are correct, but at least they are numerically
40       stable
41    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
42    o added adjoint exch routined for all exch*3d* routines
43      and updated flow directives
44    
45    checkpoint58o_post
46    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
47      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
48    o change controling S/R for writing pickup file (new S/R do_write_pickup)
49      and clean-up reading/writing of pickup files.
50    o fix local version of read/write pickup (NH part) in rotating_tank/code
51    o simplify EXCH interface:
52     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
53     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
54    o added the regrid package
55    o shelfice:
56     - add a simple boundary layer scheme to reduce noise
57     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
58    
59    checkpoint58n_post
60    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
61       local variable (not in common block).
62    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
63      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
64      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
65        to work with SingleCpuIO.
66    o add "_d 0" to real constant of pkg/cfc subroutines ;
67       update exp. cfc_exemple & tutorial_cfc_offline output files.
68    o multi-threading and IO:
69      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
70        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
71      - barrier before and after reading.
72      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
73      - avoid using MDS_WRITELOCAL for LAND pkg output.
74      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
75        common-block variables ; Allows multi-threading with master-thread IO.
76    o change default MAX_NO_THREADS from 32 to 4 ;
77      and stop cleanly when MAX_NO_THREADS is too small.
78    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
79    
80    checkpoint58m_post
81    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
82       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
83    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
84       keep global_ocean.90x40x15 (for AD testing) with former secondary test
85       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
86    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
87        add MITgcm_tutorials (= code + all the tutorials)
88    o ecco, option to compute cost for total ssh (mean+anom)
89    o consistent with addition of ptracer and ssh in pkg/profiles
90    o profiles: adding ptracer and ssh
91    o testreport: change multi-test output-file name
92      (from output.txt.{name} to output.{name}.txt)
93    o profiles: now ok for mutli-tiles case
94    o seaice: add 4 parameters for different advection schemes for area,
95      (effective) seaice thickness, enthalphy, and snow height. Their default
96      is the standard parameter SEAICEadvScheme
97    o calc_gw:
98     - add cosFacU in zonal viscous flux (harmonic.visc.).
99     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
100       of tutorial_plume_on_slope.
101    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
102    o calc_gw: true flux-form, account for horizontal grid spacing.
103      update rotating_tank results, but not plume_on_slope (affected at
104      truncation level, 11 digits).
105    
106    checkpoint58l_post
107    o calc_gw:
108     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
109     - remove side-drag for now (need to fix it); update plume_on_slope results.
110     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
111    o commit code to make SST/SSS weights spatially variable
112      (based on either variable in-situ or variable initial T/S weights)
113    o pkg/ecco:
114      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
115        now based on horizontally varying weights wthetaLev, wsaltLev
116      * cost_averagesflags now returns year indices in addition to day, month
117      * sflux balance is performed on annual basis
118        (sflxumm, sfluxmm2, bal_sfluxmm)
119      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
120        including separate counting and multipliers
121    o pkg/rbcs
122      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
123    
124    checkpoint58k_post
125    o testreport:
126     - always build in dir. "build" (if not there, mkdir build instead of building
127       & running in input)
128     - run in dir run (if it exists), in build otherwise.
129     - call prepare_run (if input/prepare_run exists)
130     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
131    o pkg/exf modifications to interpolation and rotation routines for more
132       reasonable treatment of North Pole singularity: for tracers North Pole
133       value is set to northernmost zonal-mean value, for zonal velocity it is
134       set to zero, and for meridional velocity it is set to northernmost value.
135    o pkg/exf/exf_check_range.F
136     - add tile index to diagnostics and move stop statement to the very
137       end of the routine.
138    o pkg/diagnostics: (diagnostics_main_init.F)
139      define title of isomorphic variables according to the current config.
140    o pkg/thsice with pkg/seaice dynamics:
141    - fix domain of computation (interior only, required for exf) and do exchanges
142    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
143    o towards a standard way of dealing with multi-threading in MONITOR
144      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
145    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
146       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
147    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
148    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
149    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
150       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
151    o tracer advection:
152     - clean-up and simplify calc_common_factors.F
153     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
154       advection subroutine (but still not used within DST advection S/R)
155    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
156    
157    checkpoint58j_post
158    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
159      from file (collects calls previously in FORWARD_STEP)
160    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
161    o adjoint store dir. adjusted accordingly
162    o genmake2
163      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
164    
165    checkpoint58i_post
166    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
167      on wind stress (SEAICEstressFactor defaults to 1.)
168    o Total number of Timers is finite (<=40): comment out 2 non-essential one
169      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
170    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
171      on CS-grid: no longer loosing mass.
172    o exf & curvilinear-grid: no longer modify longitude xC & xG.
173    o pkg/ggl90: fix sloppy output and fix a bug
174    o pkg/seaice: added SEAICEuseEVPpickup parameter
175      - Set to false in order to start EVP solver with
176        non-EVP pickup files when using SEAICEuseEVP
177      - fix sign error in diffusion in seaice_calc_rhs
178    
179    checkpoint58h_post
180    * Modifications for bottom topography control
181      o replace hFacC by _hFacC at various places
182      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
183      o add non-self-adjoint cg2d_nsa
184      o update autodiff support routines
185      o re-initialise hfac after ctrl_depth_ini
186      o works for 5x5 box, doesnt work for global_ocean.90x40x15
187    * Adding verification for 5x5 box (4-layer) bottom topography control
188    
189    checkpoint58g_post
190    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
191       used for mean seasonal cycle, mean diurnal cycle); add an example
192       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
193    o pkg/ggl90:
194      - add parameter (minimum surface kinetic energy)
195      - fix bug (avoiding division by zero)
196    o couple pkg/thsice to pkg/seaice:
197      - modify advection in seaice to accomodate new scalar fields to be advected
198      - only muliDimAdection scheme work with seaice/thsice
199      - mapping of thsice-variables to seaice-variables, back and forth
200      - does not break the verification experiments, but does not give the
201        desired results either
202    o pkg/seaice
203      - make (default) second order advection a bit less confusing?
204    
205    checkpoint58f_post
206    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
207      to pkg/seaice):
208      - new routines thsice_map_exf and thsice_get_exf provide the interface
209      - add an additional formal parameter to thsice_solve4temp
210    o pkg/exf:
211      - add new fields wspeed, snowprecip (to be able to couple to thsice)
212      - correct Stefan-Boltzmann constant
213      - new parameter for longwave surface emittance
214      - separate some stuff from exf_bulkformulae into new routines  
215        exf_radiation, exf_wind
216      - add new parameters and constants: longwave emissivity for ocean, ice
217        and snow, evaporation parameters over ice
218      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
219        either wind from stress or stress from wind
220    o pkg/thSIce:
221    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
222    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
223       and THSICE_CALC_THICKN
224    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
225    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
226      to make debugging easier.
227    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
228    o pkg/bulk_force:
229      - clean-up comments and parameters ;
230      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
231    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
232      generate new output for test-experiment: aim.5l_cs.thSI
233    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
234      testreport accordingly
235    
236    checkpoint58e_post
237    o SEAICE_CGRID adjoint done
238    o R_STAR adjoint implemented.
239      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
240      * need to sort out init. of h0facc, etc.
241    o Make pkg/profile fully independent of ecco,cost, etc. stuff
242      to be able to use it in pure forward.
243    
244    checkpoint58d_post
245    o upgrade simple test-experiment to tutorial example:
246     step.1: duplicate the experiment and (step.2) will remove the old copy.
247      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
248      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
249      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
250      tutorial_global_oce_biogeo    <- copy of dic_example
251      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
252      tutorial_plume_on_slope       <- copy of plume_on_slope
253      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
254      tutorial_global_oce_optim     <- empty for now (David ?)
255      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
256     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
257    o correct a sign problem in cost_scat.F
258    o obcs and ptracers: fix boundary conditions for advections schemes
259      with larger stencil
260    o thsice adjoint: start
261    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
262      completeness
263    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
264      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
265    o ptracers adjoint:
266      * avoid extensive recomputatations
267      * fix missing re-init. of gptr (missed by TAF)
268    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
269      me to turn off the excessive output to STDOUT that this package produces
270    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
271      and add those terms in Vector-Invariant formulation.
272    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
273      if the control period (xx_hfluxperiod etc) is 0
274    o in profiles pkg, clean routines and fix details
275    o in ecco pkg, reading ssh data:
276      fix problem in case the model does not start at iter0=0
277    o fix mnc-pickup/restart for ptracers
278    o new package prifiles:
279      code to compute profile-based cost by Gael Forget
280      (modifs in ecco, ctrl, autodiff)
281    o Benign bug fix in initialization (spotted by M. Mazloff) of
282      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
283    
284    checkpoint58c_post
285    o adjoint: finish NLFS adjoint and provide reference output in
286      verification/global_ocean.90x40x15/results_ad_nlfs
287    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
288      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
289      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
290      with SEAICE_CGRID defined.
291    o move calendarDumps from "data" to "data.cal" and clean-up the code
292      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
293    o add useEXF & useCAL flags (for now, set in hard-coded way)
294    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
295      (were missing in NH mode, and wrong in quasihydrostatic mode).
296      waiting for Chris updated version of calc_gw to add those CALLs.
297    o fix bug in quasihydrostatic S/R ;
298      add a test for this option: global_ocean.90x40x15.qshyd
299    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
300      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
301    o add on/off flag useOffLine for package OFFLINE
302    o seaice:
303      - modify advection so that it works also on the C-grid
304      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
305        problem in multi-tile runs with C-grid
306      - add flags for clipping ice velocities and/or masking solver forcing
307      - fix drag (ocean on ice) formulation and a bug that caused noise in the
308        C-grid solver
309      - added a few comments to seaice_diffusion.F
310      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
311        are now exclusive)
312      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
313        required re-ordering the code a little:
314       + make DAIRN global variable (defined in SEAICE)
315       + move computation of the viscosities eta and zeta into a new separate
316         routine (because I need to recompute them in seaice_ocean_stress.F)
317    
318    checkpoint58b_post
319    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
320      update output.txt of exp. aim.5l_cs.thSI
321    o various mnc cleanups and improvements:
322      + shrink lookup tables by factor of ~4
323      + better error reporting when running out of lookup space
324      + able to handle longer path/file names (up to 500 chars)
325    o adjoint:
326      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
327      - TBD: "hidden" mom_vecinv recomp. in dynamics
328    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
329     (allow to differentiate between forcing components using new integer flags:
330      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
331     and add new flag to put Dissipation tendency out of Adams-Bashforth.
332    o ecco
333      - enable trend removal from SSH anomaly obs.
334    o adjoint
335      - a fix for PmEpR when #undef EXACT_CONSERV
336      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
337      - try to fix "hidden" recomp. in forward_step for NLFS
338        (NLFS seems broken sometimes after I checked it in)
339    o seaice:
340     - add c-grid version of the dynamic solver:
341       + three new routines that are the c-grid substitute lsr, dynsolver
342         and ostres
343       + put a few fields that were local to dynsolver into global common
344         blocks, so that I can move the computation of stresses etc into
345         seaice_lsr (saves coding but may break the adjoint).
346     - replace more hardwired parameters by runtime parameters
347     - add ice masks that mask the rhs of the implicit solvers where there
348       is no ice (commented out in seaice_dynsolver, because i am not sure
349       if this works properly), eventually this should replace the clipping
350       of ice velocities in seaice_dynsolver to +/-40cm/s.
351    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
352      include it only where its needed
353    o move balancing of fluxes before the call of external_forcing_surf
354    o seaice:
355      - correct units of turning angles (now they are really in degrees)
356      - move computation of GWATX/Y out of main routine into dynsolver
357      - initialize GWATX/Y in seaice_init
358    o Apply mask on Fresh-Water flux (needed for SSH forcing).
359      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
360    o seaice: add runtime flags for turning angles (default to zero)
361    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
362      and trend from exf forcing and ctrl control adjustments
363    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
364      (since checkpoint57x_post)
365    o change the default rotation period to 86164.s = the Earth rotation
366    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
367      and based on a reference stratification. Tested within hs94.cs-32x32x5.
368    o seaice advection: add code for choosing between the default (2nd order
369      central differences) and multiDim advection schemes provided by
370      pkg/generic_advdiff
371    o seaice:
372      - removed all references to SEAICE_GRID.h fields from
373        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
374        (cubed-sphere configuration will change a little)
375      - grid computations in seaice_init are obsolete now.
376      - cleaned up code a little so that is easier to read (hopefully).
377      - added new (better?) discretizations of default advection and diffusion
378        (turn on with SEAICEuseFluxForm)
379      - replace 1 in 3d global fields by kSurface in growth.F
380      
381    checkpoint58a_post
382    o seaice:
383      - bug fix in advect.F
384    o shelfice:
385      - separate shelfice load anomaly from pload (breaks with time
386        dependent forcing), => introduce constant field shelficeLoadAnomaly.
387        Its default is 0., but it may be computed more cleverly from (unknown)
388        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
389        done offline. A good approximation of the pressure load anomaly is
390        necessary to avoid large initial adjustment processes underneath
391        deep-reaching shelfice.
392      - small fix in ISOMIP shelfice_thermodynamics
393      - add more sophisticated thermodynamics of Hellmer (1989), this is
394        now the default
395      - give a few constants more intuitive names
396    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
397      if bulk formulae are used in long integration (especially EmPmR). Turn
398      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
399      if balancePrintMean, the imbalance that is substracted is printed to
400      STDOUT.
401    o fix bug (typo) in obcs_apply_eta.F
402    o add a new package shelfice which enables us to model the circulation
403      underneath shelf-ice with draughts of hundreds of meters.
404     - works
405     - to do: + include improved thermodynamics
406              + check whether kSurfC (from model/inc/SURFACE.h) can be used
407                instead of new field kTopC
408              + can we use topoFile, Ro_surf and existing code in ini_depth.F
409                instead of new field R_shelfIce and new code in ini_depth.F
410                and ini_mask_etc.F?
411              + adjust vertical mixing schemes?
412    o seaice pkg:
413     - add a cpp-flag to include a simple formula for a salinity dependent
414       freezing point of sea water at the surface
415     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
416       meridional stresses are now different (and hopefully correct)
417    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
418       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
419       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
420    o pkg/diagnostics: add options and parameters for regional-statistics
421       diagnostics ; define regions by reading a region-mask from a file
422       (might add other options later)
423    o pkg/bulk_force:
424     - add option and parameters to use AIM surface-flux formulae.
425     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
426       others forcing fields (defined in PARM05, parameter file "data") are loaded
427       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
428     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
429     - use the right EXCH call for uwind,vwind (to work on CS-grid).
430     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
431       and parameters (note: calcWindStress replaces .NOT.readwindstress).
432     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
433    
434    checkpoint58
435    o add "--embed-source" option to genmake2 which, when the supporting
436      tools can be compiled (as determined by genmake2) will turn on the
437      embed_files package which then embeds the entire MITgcm source code
438      (*.[fFhc] + Makefile) used for the build within the executable
439      - requested by CNH but off by default
440      - adds a paltry <9MB to the mitgcmuv executable in most cases
441      - only writes the output when useEMBEDSRC in eedata is true
442    o clean up 3-dim. relaxation codes:
443      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
444      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
445      * Thanks to Tom Haine for testing!
446    
447    checkpoint57z_post
448    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
449      affects output (@ truncation level) of exp. plume_on_slope ; updated.
450    o fix the pickup behavior for obcs in combination with ptracers
451    o fix a bug in ptracers_external_fields_load
452    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
453      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
454    o transfered surface NH pressure to eta field (if exactConserv).
455    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
456         and update lab_sea output.txt file.
457    o completing 3-dim. relaxation code: additional term
458         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
459      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
460      * At compile time, in "EXF_OPTIONS.h" set
461          #define  ALLOW_CLIMTEMP_RELAXATION
462          #define  ALLOW_CLIMSALT_RELAXATION
463      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
464          tauThetaClimRelax3Dim = 15552000.0,
465          tauSaltClimRelax3Dim  = 15552000.0,
466      * 3 cases:
467          1) Use a constant-in-time 3-dim. field
468          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
469          3) Real-time relax. to time-evolving prescribed field
470    o Adding Laplacian-type smoothness constraint on
471      initial and boundary (forcing) controls (ic, bc)
472      * enable at compile-time via
473        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
474      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
475      * Absolute scale somewhat unclear so far
476      * no area weighting was included since no other cost term does so far
477    
478    checkpoint57y_post
479    First step for a NLFS adjoint
480    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
481    o new init. routines for calc_r_star, calc_surf_dr
482    o still need to deal with ini_masks_etc
483    o testreport seemed happy
484    checkpoint57y_pre
485    
486    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
487    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
488    o add new offset feature to offline pkg (plus minor cleanup)
489    o cfc fixes for final year of integration
490    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
491      be in GCHEM_OPTIONS).
492    
493    checkpoint57x_post
494    o fix testreport Pb in multiple test experiment.
495    o cleanup our namelist syntax in verification:
496      - make it more F95 standards compliant (some work still needed)
497      - allows the vast majority of our tests to work with gfortran
498    o Non-Hydrostatic:
499     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
500     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
501    o Allow to apply AB on T,S rather than on AB(gT,gS):
502     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
503     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
504       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
505     - need a "clever" read_pickup to restart from the other AB formulation
506    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
507    o remove some unused variables (reduces number of compiler warnings)
508    o adjoint
509      * Disable useVariableViscosity for adjoint for time being
510        (there are a number of extensive recomputations)
511      * Initialize certain variables needed for adjoint
512    
513    checkpoint57w_post
514    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
515                 fix the singleCpuIO RS version of MDSWRITEFIELD
516       and add a WARNING if using globalFiles=T with multi-processors.
517    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
518      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
519    o tracer advection scheme:
520      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
521       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
522       was not very convenient).
523      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
524       (further tests needed for the implicit DST & Flux-Limiter schemes).
525    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
526      and sRef for convenience, handy, when you want to initialize
527      ptracers in a large domain with a constant non-zero value. Also,
528      untangle ptracers_init.F a little.
529    
530    checkpoint57v_post
531    o change dome exp. to use variable viscosity in side-drag terms.
532    o remove all the files from the cfc_offline test since they are now
533      incorporated into tutorial_cfc_offline which has been producing
534      identical results for a few days of testing
535    o add new parameter: sideDragFactor to enable half-slip-side BC
536      and change side-drag S/R to use viscosity from mom_calc_visc
537      (can switch back by setting sideDragFactor=0.); affects results at
538      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
539       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
540    o vorticity & strain are now computed without masking, to account for
541      no-slip-side BC in variable viscosity calculation ; mask is applied
542      anyway later on, before computing advection/coriolis terms.
543    o modify exp4 to test new obcs support for reading from external files
544      and for passive tracers
545    o fix behavior of ptracers_monitor when monitor output is written to a
546      netcdf-file; still not independent of monitor.F (writes in the same
547      file).
548    o change default value of tRef (put a uniform, meaningful value for ocean
549      & atmos) and initialize sRef (was missing, as Martin mentioned).
550    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
551      to be proportional to enstrophy dissipation length.  Thus,
552       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
553      This is now consistent with Smagorinsky and with the manual.
554    
555    checkpoint57u_post
556    o OBCS and PTRACERS: add open boundary support for passive tracers
557      - either use homogenous (pseudo) v.Neumann conditions or prescribe
558        OB-values from file; this is not different from the way theta and salinity
559        are treated
560      - however, Orlanski-radiation conditions are not supported, and the model
561        will stop if you use pTracers and Orlanski at the same time.
562      - beefed up the rountine obcs_external_fields_load: now only those open
563        boundary values are overwritten with values from files for which there
564        are really files, otherwise the OB-fields remain untouched. This makes
565        it possible to use different OBs at different ends of the domain (as
566        with EXF)
567    o reduce number of exch calls in shap_filt (s2).
568    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
569      truncation level) 4/5 MLAdjust test results (11&12 digits match).
570    
571    checkpoint57t_post
572    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
573    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
574      same truncation, independent of the face number: affects affects several
575      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
576    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
577      note that biharmonic viscosity + no-slip was not tested in any experiment.
578    o fix bug in non-linear free-surf side-drag ; generate new output for
579      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
580    o make mnc honor the writeBinaryPrec flag for most kinds of output
581    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
582    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
583      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
584    o add brackets in multi-terms sum to get same truncation, independent of
585      the face number (manage to get exactly same value of gU,gV at the cs-edge)
586      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
587    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
588      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
589      a maximum grid-scale Reynolds number.  Also, changes all length calculations
590      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
591      Suggested values of viscosity parameters found in mom_calc_visc.
592      Many new viscosity diagnostics available.
593    
594    checkpoint57s_post
595    o Add clearing-house for viscosity calculations, mom_calc_visc and
596      correct numerous bugs in LeithD and Smagorinsky discretizations.  
597      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
598      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
599      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
600      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
601      The Strain-Tension form is now called with useStrainTensonVisc=.true.
602      ViscAhStrain and viscAhTension are now retired.
603    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
604    o In response to JMC's bug report, genmake2 now ignores any soft-links
605      that it finds in the *current* directory when searching for files.
606      Soft-links found in any other source directories will still work as
607      they did before.
608    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
609      a C routine to unlimit the stack size
610    o mnc-ify pkg/aim snapshot vars
611    o mnc-ify pkg/land as requested by Daniel
612    o various changes to mnc including:
613      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
614      - output can now be grouped so that all files within a group
615          change the ITER portion of their names in lock-step together
616      - can now read ("global") PER-FACE (in addition to PER-TILE) files
617          and works with both EXCH1 and EXCH2 (but needs more testing)
618      - writing works for all verification test cases w/ g77 on Linux
619    
620    checkpoint57r_post
621    o make MNC variable initialization happen earlier
622    o add diagnostics for (almost) each term of the momentum Eq.
623    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
624    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
625    o remove MINIMAL_TAVE_OUTPUT option ;
626      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
627    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
628      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
629    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
630    o add time-dependent SST, SSS control
631    o cost terms in ecco/ modularized (new cost_generic.F)
632    o cost_averages routines are modularized (new cost_averagesgeneric.F)
633    o new infrastructure for seaice model vs. obs misfits in seaice/
634      * driver from the_main_loop.F is seaice_cost_driver.F
635      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
636      * gradient check in Exp. 6a of natl_box_adjoint/
637    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
638      (see README file)
639    
640    checkpoint57q_post
641    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
642    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
643      - bug was reported by Jean-Michel and Ian Fenty
644    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
645      update exp. cpl_aim+ocn output.
646    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
647      Needed for high-res. runs with large global files
648      to be able to limit tapelev size
649    o Changed some tests for adjoint:
650      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
651      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
652      * global_ocean.90x40x15/ back to default 3-level checkpointing
653    o Modifications to enable scripted COMMON to MODULE conversion
654      * verification/OpenAD/code/ has necessary scripts and description;
655      * converts, compiles and runs successfully;
656    
657    checkpoint57p_post
658    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
659    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
660      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
661    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
662    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
663      (was already the case for dissipation with mom_vecinv,
664       and also the case for grad.PhiHyd when staggered-timeStep)
665      This will allow to put dissipation out-off the AB time-stepping.
666     Unfortunately, affects truncation error. Update output of exp. that "fails"
667      (cg2d matching number) and leave the others for later: front_relax(10),
668      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
669      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
670    
671    checkpoint57o_post
672    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
673      (2) its ready to be documented during the 20050801 DocFest
674    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
675      for ideal_2D_oce and lab_sea on linux_ia32_g77
676    o set to #undef CTRL_SET_OLD_MAXCVARS_30
677      in global1x1_tot/code_seaice_adj to access indices 32, 33
678      (worth another tag)
679    
680    checkpoint57n_post
681    o adding precip control xx_precip 32
682    o adding swflux control xx_swflux 33
683    o Replacing 10 forcing penalty cost routines by 1 generic.
684    o Implementing partitioning in time-mean and variable adjustment
685      for atmos. state.
686    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
687    o in natl_box_adjoint:
688      * updated exp 1 to 10
689        (but does not have time-mean vs. variable split results yet)
690    o updated global1x1/*_seaice_adj/
691      to incorporate latest changes
692    o enable useSingleCpuIO for mdsio vector routines
693      (applies in particular to tapelev I/O)
694    o removed inefficient K-loop in all active_file*control*.F
695    
696    checkpoint57m_post
697    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
698      and advect_cs (use EXCH-2 and standard cs-32 grid files).
699    o pkg/exch2: filling of face-corner halo regions is optional
700      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
701    
702    checkpoint57l_post
703     tag before updating tutorials (pre-release-2)
704    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
705       for output and interpolation of input fields onto model grid)
706    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
707       Affects results of exp. rotating_tank ; update output.txt.
708    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
709          and taking the square quantity and/or using a fraction-weight field.
710    o fix aim_diagnostics_init.F mate numbers.
711    o add mnc output capability to diagnostics/diagstat and update
712      our cvsignore files for the ACSII output generated
713    
714    checkpoint57k_post
715    o lab_sea now uses diagnostics package and provides a suite of
716      new EXF diagnostics output.
717    
718    checkpoint57j_post
719    o exf
720      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
721        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
722        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
723      * extended diagnostics output
724        - now includes all EXF variables
725        - hs, hl moved to common block
726        - separate S/R for diagnostics, called after ctrl vector is added
727        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
728        - EXFqnet contains true Qnet (i.e. includes qsw)
729      * updated verif. lab_sea, global_with_exf
730      * Rearranging hflux (exf_mapfields -> exf_getforcing)
731        to ensure that diagnostics sees a true EXFqnet
732    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
733    o diagnostics pkg: change pointers so that 1 diagnostic can be used
734      several times with different frequencies.
735    o mnc-ify the thsice package as requested by Daniel Enderton
736      - the monitor--MNC output needs work
737      - many attributes need to be added (most are currently blank)
738    o mnc-ify theaim_v23 package as requested by Daniel Enderton
739      - many attributes need to be added (most are currently blank)
740    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
741    o add Sadourny like discretization to the 4th.O vorticity advection scheme
742    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
743      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
744         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
745    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
746     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
747    
748    checkpoint57i_post
749    o Diagnostics package was changed: diagnostic allocation is now deactivated
750      by setting an empty file name in the namelist (used to be by setting 0 frequency)
751    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
752      add 1rst Order upwind vertical Shear.
753    o add a quick fix for A/B checkpointing in OFFLINE mode
754    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
755      end-run around the C/Fortran linking horror in eesup/src/timers.F
756    o added pkg/runclock: allows user to terminate run based on wall clock
757    o added non-hydrostatic scaling parameter: nh_am2
758    o pkg/my82: futile attempt to make results compiler-independent by adding
759      some "_d 0", etc. no effect.
760    o for mnc output, fill the 'T' coordinate var with myTime and create a
761      separate 'iter' variable for iteration count
762    o pkg/diagnostics:
763      add new capability: output of Global/Regional & per-level statistics ;
764      tested against monitor output (including land & thSIce) on various exp.
765    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
766    
767    checkpoint57h_done
768      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
769      data.diagnostics, data.gchem, data.ptracers) is done.
770    
771    o pkg/diagnostics: prepare for Global/Regional statistics.
772      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
773    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
774      and rename it: DIFFERENT_MULTIPLE
775    
776    checkpoint57h_post
777    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
778    o pkg/diagnostics: change output frequency, now in seconds (instead
779      of Nb of iterations). This requires to change data.diagnostics.
780    checkpoint57h_pre
781    
782    o in mnc, let the user create the output dir if both mnc_outdir_date
783      and mnc_outdir_num are false
784    o add fflags() to pkg/diagnostics which allows one to specify, on a
785      per-file basis, the file precision [default behavior is unchanged]
786    o added diagnostics to pkg/kpp, including computation of mixed layer
787      depth based on a temperature/density criterion
788    o updated verification/natl_box to test the new pkg/kpp diagnostics
789    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
790    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
791    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
792      not mnc -- this mistake was found by JMC and is now corrected
793    
794    checkpoint57g_post
795    o add Adams-Bashforth 3rd Order time stepping:
796      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
797      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
798    checkpoint57g_pre
799    
800    o make lambda[Theta,Salt]ClimRelax spatially varying
801      (default remains spatially uniform constant based on tau)
802    o added new control variables
803      * init. uVel, vVel, etanN
804      * lambda[Theta,Salt]ClimRelax
805    o separate masks used for ctrl_pack/unpack 'from write_grid' output
806      (suggested by G. Forget)
807    
808    checkpoint57f_post
809    o add parameter "baseTime" = model base time = time at iteration zero
810      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
811      account for baseTime shift
812    o move Coriolis arrays from PARAMS.h to GRID.h
813    checkpoint57f_pre
814    
815    o mnc-ifying the seaice package
816    o introduced an alternative length scale calculation for use in the limiting
817      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
818    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
819    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
820      as well as grad(vort3).  Made it compatible with both approximate form
821      for the cubed sphere and full form of these gradients.  Added flag
822      useFullLeith to select between approximate and full form.  
823    o add "d0" in getcon.F to reduce differences between compilers/platforms
824      update output.txt of exp. fizhi-gridalt-hs
825    o change port_rand funtion to allow to set the seed.
826    o fix obscure MNC bug involving conversion between reals and integers
827      - it caused no problems with certain (eg. gcc, ifc) compilers but the
828        new version is now more standards-compliant
829    o adjoint-related modifications
830      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
831      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
832      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
833    
834    checkpoint57e_post
835    o Adding eddy stress controls a la Ferreira et al.
836    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
837    
838    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
839      update output.txt of exp. fizhi-gridalt-hs
840    o add more "Z" dimensions and associated coordinate vars to MNC
841    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
842    o parameter calendarDumps: when set, approximate months (30-31 days) and years
843      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
844      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
845      months and years.  Requires pkg/cal.
846    o diagnostics: add pickup functionality
847      - off by default for backwards compatibility
848      - current version only uses MDSIO -- MNC will be added
849    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
850    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
851    
852    checkpoint57d_post
853    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
854    o modify verification/ideal_2D_oce so that it tests the creation of mnc
855      output from the diagnostics package
856    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
857    o make genmake2 more portable by using ".$FS" instead of ".f" for more
858      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
859    o add coordinate variables to the MNC output from the diagnostics package
860    o change MNC-flags default value: true when useMNC=TRUE
861    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
862      the ability (off by default) to read the grid information using MNC
863    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
864    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
865    o do snap-shot diagnostics at the middle of the time-interval (instead of
866      at the end).
867    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
868      new test for AIM with thSIce + slab-ocean
869    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
870    o move state variable diagnostics to the beginning of the time step ;
871      (note: still needs some work specially for snap-shot diagnostics)
872      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
873    
874    checkpoint57c_post
875    o Change testing option (-ieee) to get closer agreement between g77 & ifort
876    o generate new output.txt files on faulks with g77 & the new -ieee option
877    checkpoint57c_pre
878    
879    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
880      update output.txt of exp. global_ocean.90x40x15
881    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
882      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
883    o add saltFlux(+File) forcing capability with periodicExternalForcing
884    o allow to use pkg diagnostics for GM-Redi & ThSIce output
885    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
886    o improvements for the MNC output from DIAGNOSTICS:
887      - correct handling of the unlimitied dimension
888      - all dims now have associated coordinate variables
889      - variables located at U, V, and Corner ("Z") points are now written
890        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
891        *all* data points are output
892    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
893    o added pkg/seaice/seaice_monitor.F
894    o mdsio_readfield.F can now read files visible only to master MPI process.
895    o pkg/seaice: some test code for ice-modified ocean stress
896    o exf_getffields interpolation defaults to bilinear for all scalar forcing
897      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
898      spurious negative numbers for precipitation and humidity.  Will cause
899      some small numerical differences for integrations using pkg/exf/exf_interp.F.
900    o pkg/ctrl/
901      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
902        May be enabled via doPackDiag
903      *  introduce z-scaling of
904         + gradient (doZscalePack) and
905         + control (doZscaleUnpack)
906    o pkg/mdsio/
907      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
908      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
909    
910    checkpoint57b_post
911    o simplify options in diagnostics_fill arguments (remove weird combinations)
912    o fix MNC coordinate variables so that they now contain per-face index
913      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
914      general, EXCH2 grids are only aligned to a "local" coordinate system
915    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
916    o Implement instantaneous output within pkg diagnostics:
917      setting a negative frequency in data.diagnostics produces
918     "snap-shot" output (as opposed to time-average if freq > 0)
919    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
920      NOTE: change ptracer diagnostics name: use 2 characters to work with
921            more than 9 tracers. Add also diagnostics of advect & diffus flux.
922    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
923      becomes the coordinate variable for the 'T' dimension
924    o add CF-style coordinate variables to MNC
925      - just a first cut:  numbers are meaningless on the cubesphere and
926        missing along the T axis but otherwise it works!
927    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
928    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
929    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
930      this is based directly on what the model compute, so that the content of
931      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
932    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
933    o clean up build options files for SunOS, in particular
934      - remove -traditional from xmakedepend
935      - change -xarch=v9 to -xarch=native for f77
936      - restore use of make (not gmake)
937      - add CC=gcc if using g77
938    o changes per discussion of AM, JMC, & EH3 today:
939      - move redundant "grid" variables out of "state" -- in preparation of
940        creating proper CF-style coordinate variables and in recognition
941        that any/all grid variables can be easily copied (eg. w/NCO) from
942        the grid files into any of the other NetCDF files
943      - *always* output grid variables with MDSIO (this will eventually be
944        changed)
945      - output MNC grid file if useMNC is true
946    o every instance of _END_MASTER() has been found and replaced with
947      _END_MASTER( myThid ) in order to satisfy certain picky Sun
948      preprocessors
949    o re-arrange diagnostics pkg initialisation:
950     - allow each package to extend the available diagnostics list
951     - add some checking and fix small problems (multi-threaded, ...)
952     - new S/R diagnostics_fill (replace fill_diagnostics):
953       look through the short list of active diag. (instead of the long list)
954       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
955    
956    checkpoint57a_post
957    o this set of changes restores TAMC compatibility
958      tested for global_ocean.90x40x15 adjoint on trough
959      (what a pain)
960    
961    checkpoint57a_pre
962    o some modifs in tools/build_options for sunos
963    o call ctrl_pack for ctrl at end for optimcycle=0
964    
965    checkpoint57
966    o add horizontal bi-harmonic viscosity for vertical velocity
967      - new parameter viscA4W (defaults to viscA4)
968      - affects only non-hydrostatic code
969      - to be done: no-slip lateral boundary conditions
970    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
971    o implement Implicit Vertical advection for pTracers
972    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
973      (implemented also for implicit vertical diffusion & advection)
974    o OBCS: extend application of tracer open boundary conditions
975      to a strip beyond the boundary of width Olx/Oly
976    o add call monitor to TAF set of required calls (flow directives)
977      and include in natl_box_adjoint
978    o untangle a few ifdefs related to cost, ctrl, autodiff
979      untangel a few ALLOW_ECCO_OPTIMIZATION
980    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
981      (theta2, salt2 in ecco_cost_weights)
982    
983    checkpoint56c_post
984    o OBCS as control variables
985      - update ctrl_ad_diff.list, obcs_ad_diff.list
986      - remove balance of obcs controls from default
987      - fix index bug nobcs in ctrl_init
988      - fix dummy fields filen in ctrl_pack
989      - add dummy weights for obcs
990    o lsopt: comment out fort.94 output
991    o optim:
992      - remove unnecessary header files
993      - adjusted namelists
994      - add xerbla.F to Makefile
995    o exf:
996      - multiple modifications of exf_check_range
997      - unit change in exf_init_runoff from [m/year] to [m/s]
998    o mdsio:
999      - i/o-vector change debugLevel from debLevA to debLevB
1000    
1001    checkpoint56b_post
1002    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1003      is called from DO_THE_MODEL_IO
1004      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1005      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1006      - clean up PTRACERS_WRITE_TIMEAVE a little
1007    o add another verification experiment that tests both the cfc-pkg and
1008      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1009      reactive tendencies treated inline with regular timestepping
1010    o testreport previously did a lousy job of comparing small numbers, so
1011      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1012      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1013      testreport.
1014    o ptracers_monitor: bug fix for MPI
1015    
1016    checkpoint56a_post
1017    o GCHEM: finish reorganizating the package
1018      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1019        (introduces another 3D-array for each passive tracer, but only if
1020        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1021        gchemTendency is not needed because the timestep is done separately)
1022      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1023      - GCHEM is now---more or less cleanly---separate from PTRACERS
1024      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1025        so clear to me how that should be done in a general way.
1026    o CFC: improve formatting of output in CFC_ATMOS
1027    o PTRACERS:
1028      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1029        that ALL experiments with ptracers enable can be checked. This makes
1030        GCHEM_MONITOR obsolete.
1031      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1032        monitorFreq
1033      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1034    o add PTRACERS (PTR0[1-5]) to testreport output
1035    o exf_check_range:
1036      * default changed to .TRUE.
1037      * will check values for niter0 if debLevA, every timestep if debLevB
1038      * STOP in exf_check_range if 'out of range'
1039      * range chosen generous to allow for potential extema
1040      TBD: a version with stricter range
1041           permitted range would be runtime parameters
1042    o GMredi:
1043      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1044      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
1045      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
1046    o GCHEM:
1047      - move call to GCHEM_FORCING_SEP, so that it is now called before
1048        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
1049      - introduced a useGCHEM runtime flag and applied it everywhere.
1050      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1051        this flag is now only visible within GCHEM-pkg routines.
1052      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1053        be replaced by a 3D array that is computed before thermodynamics; for
1054        this, the tracer ID iTracer had to be included into the parameter list
1055        of ptracers_forcing
1056      - set up forward_step to call gchem_forcing, that will replace
1057        gchem_forcing_int in ptracers_forcing
1058      - cleaning up
1059    o small cleaning of exch2: remove files that are also in eesupp/src
1060    
1061    checkpoint56
1062    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
1063    o mnc: cleanup "full" files--fixes out-of-memory problem
1064    o ECCO-GODAE
1065      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
1066      * fully merged and updated from SIO code
1067        windstress sign change affects
1068        - exf_inscal_[u/v]stress
1069        - sign of xx_tau[u/v] adjustments
1070        - signs in cost_scat
1071      * ctrl_get_gen: avoid update of tau[u/v] for first few days
1072      * natl_box_adjoint updated and compressed
1073      * 2-level checkpoint switch added
1074        (tested in EXP. 1 of natl_box_adjoint)
1075      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
1076    o SVD
1077      * first complete, non-hacked version for SVD calculations
1078      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
1079        performed via direct access files admtlm_vector.it????
1080        (via ctrl_[un]pack)
1081      * optimcycle is used for ARPACK iteration counter
1082        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
1083      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
1084        and add linear transforms where necessary
1085      * controls are initial/final SST, SSS (can be extended; need to check
1086        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
1087    o mdsio: filename info to both stderr, stdout
1088    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
1089      from sign change
1090    
1091    checkpoint55j_post
1092    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
1093      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1094    o add consistent build directories and .cvsignore files to verification
1095    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
1096    o make all subroutines 30 or less characters in length for certain older
1097      compilers to work (a thorough search only turns up two routines in
1098      pkg/ptracers)
1099    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
1100      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1101    
1102    checkpoint55i_post
1103    o change arrays for total vertical diffusivity (2.D if explicit,
1104      3.D if implicit) ; each ptracer uses its own background value.
1105    o added mnc/NetCDF output capability to ocn_compon_interf
1106      - added bits to verification/cpl_aim+ocn so that it can run on
1107        ITRDA and other clusters without the mpirun "-wd" option
1108    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
1109      configuration
1110    o give MNC the ability to create additional files rather than
1111      exceeding a specified file size limit "MNC_MAX_FILESIZE"
1112      - the default is just less than 2GB which is a practical limit
1113        on many systems
1114    o Compute the non-local term using either KPP vertical diffusivity (=default)
1115       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
1116    
1117    checkpoint55h_post
1118    o add verification test "vermix"
1119    o remove all the *_ioinc flags and replace with the single global
1120      outputTypesInclusive flag
1121    o allow to set a vertical profile of vertical diffusivity for T & S
1122    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
1123    o useMNC moved from data.mnc to data.pkg
1124    
1125    checkpoint55g_post
1126    o Renaming carbon AD experiments to comply with testreport conventions
1127    o Updating adjoint of Held-Suarez hs94.1x64x5
1128    o Fixing directives for non-ECCO forward_step, after ECCO directives
1129      have been fixed to avoid recomp. of do_oceanic_phys
1130      Works well for global_ocean.90x40x15,
1131      but recomp. issue remains for carbon
1132    o Updating adjoint output for natl_box_adjoint after
1133      pkg/ecco has been modified (see taga c55d_post)
1134    
1135    checkpoint55f_post
1136    o rename to timeave_init_fixed
1137    
1138    checkpoint55e_post
1139    o some delicate re-shuffle of store directives to avoid one
1140      extra call of do_oceanic_physics
1141      affects ecco_the_main_loop.F, do_oceanic_physics.F
1142      checkpoint_lev1_directives.h
1143    o NB: this may break global_ocean adjoint temporarily,
1144      but it is clear how to fix it. Will do later, need this now.
1145    
1146    checkpoint55d_post
1147    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1148    o ecco_cost_weights is modified to 1x1 runs
1149    o modifs to allow observations to be read in as
1150      single file or yearly files
1151    o enable to read exf forcing fields as either
1152      single file or yearly files (flag useExfYearlyFields)
1153    checkpoint55d_pre
1154    
1155    o switch between 2-level and 3-level checkpointing
1156    o add ability of MNC to write local and "partial" (eg. 2D slices where
1157      the full 3D field is never actually stored) arrays to NetCDF files
1158      with the correct (that is, the complete multi-dimensional) set of
1159      array indicies
1160      - used in mom_vecinv() to write the diagFreq output
1161      - tested (demonstrated) in verification/aim.5l_cs
1162    o further mnc-ification
1163      - add verification/lab_sea to the list with mnc setups
1164      - fix undefined mnc v-names in cd_code
1165      - add kpp to mnc output (both snapshot and timeave)
1166    o non-hydrostatic code
1167      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1168        in calc_gw.F
1169      - defaults to viscAh
1170      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1171        friction or Leith) in non-hydrostatic mode, as long as there is
1172        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1173    o pkg/cost
1174      extend simple cost functions to treat time mean quantities
1175      (T,U,V) via cost_accumulate_state from cost_tile
1176    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1177        be 2 times larger than the minimum size the advection scheme requires.
1178        now get a perfect conservation of salt in advect_cs test-exp (updated)
1179    o GGL90 (Gaspar's TKE mixed layer)
1180      - add horizontal diffusion of TKE, requires exchanges in
1181        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1182        default. In OPA there is no horizontal diffusion of TKE but the
1183        mixing coefficients are computed from a horizontal average of TKE of
1184        6 points or so. I think that diffusion has a little more physical
1185        justification.
1186      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1187        was in vain)
1188      - mask tke-variable in ggl90_init
1189    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1190    o fix biharmonic diffusion on CS-grid.
1191    o more obcs stuff
1192      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1193        for reading boundary values. This routine is called from
1194        obcs_prescribe_read
1195      - updated obcs_check
1196      - changed sponge layer relaxation parameter units for days to seconds
1197      - turned off sponge layer by default
1198      - changed argument list of OBCS_CALC to myTime+deltaTclock
1199      - fixed about 35 bugs in obcs_external_fields_load
1200    
1201    checkpoint55c_post
1202    o obcs stuff
1203      - new runtime flags useOBCSprescribe, useOBCSbalance
1204      - re-arranged obcs_calc
1205      - moved exf_getobcs to obcs_prescibe_read
1206        obcs_prescibe_read is called after ORLANSKI stuff
1207        and independent of it (executable can contain all).
1208      - updated obcs_check
1209      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1210        These may be necessary only if tangential velocities are
1211        prescribed at OB, not sure, needs testing.
1212    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1213      which simplifies the calls and passes the ifc check-bounds test
1214    
1215    checkpoint55b_post
1216    o add a 2D scalar, Z location, exchange_2 routine.
1217    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1218      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1219      affects advect_cs results (for the wrong reason): update output.txt
1220    o use a more standard discretization for biharmonic viscosity ;
1221     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1222      affects results of dome set-up: update output.txt
1223    o fix gad_advection.F (CubedSphere part), back to version 1.23
1224    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1225    
1226    checkpoint55a_post
1227    o merged code to
1228      * prescribe/read time-dependent open boundaries
1229        (works in conjunction with exf, cal)
1230      * sponge layer code for open boundaries
1231      * each boundary N/S/E/W now has its own CPP option
1232        (healthy for the adjoint)
1233    
1234    checkpoint55
1235    o up-to-date adjoint of previous breaks
1236      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1237      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1238      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1239      - carbon: * remove tr1-related adjoint verification
1240                * add ptracer as control variable
1241    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1242      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1243    
1244    checkpoint54f_post
1245    o in verification/carbin/ remove experiment related to
1246      ALLOW_PASSIVE_TRACER (array tr1 etc)
1247      code_ad/ input_ad/ results_ad
1248    
1249    o add two new packages
1250      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1251        + subject to optimization (memory)
1252      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1253        + subject to reordering (many GOTOs in the original code)
1254        + so far opps is called for every (i,j) point, and then operates in
1255          the vertical; one may want to reorder the scheme in order operate in
1256          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1257          fields)
1258    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1259      - all verification tests compile and run with linux_ia32_g77
1260      - defaults are compatible with current input files--nothing
1261        should change if you were not previously using MNC
1262      - MNC output has been added in numerous places (eg. timeave)
1263        but there are still a few writes not yet do-able with MNC
1264        (this is in progress)
1265      - flags now allow for either/or/both use of MDSIO and MNC and
1266        documentation will soon follow
1267      - numerous small formatting cleanups for ProTeX
1268    o add version info (via BUILD_INFO.h) to MNC and stdout
1269    
1270    checkpoint54e_post
1271    o add two new packages
1272      - pp81 (Packanowski and Philander, 1981), Richardson number and
1273        stratification dependent mixing
1274      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1275      - these scheme operate in a similar manner as KPP (without ghat, of
1276        course), however there is only one diffusivity that is used for both
1277        temperature and salinity (and passive tracers)ç
1278    o add offline package
1279    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1280      provided by Stephanie Dutkiewicz
1281    o genmake2: add ability to search for C compilers and cleanup test output
1282      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1283    
1284    checkpoint54d_post
1285    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1286    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1287      leading to additional shift by 5 days each year of integration
1288       (i.e. leading to considerable offset over the years)
1289    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1290    o start with no AB and no initial filtering (staggerTimeStep):
1291      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1292    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1293      (external loading & cpl import/export stay in forward_step.F)
1294    o update coupling interface to work with new staggerTimeStep
1295    o change MDSIO ptracers_pickup.
1296    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1297    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1298    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1299    
1300    checkpoint54c_post
1301    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1302      this affects (truncation error) output.txt of test-exp:
1303       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1304    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1305    o change Qnet to always be the net heat flux, (+upward).
1306      affects (truncation error) output of natl_box exp.: updated
1307    o define the max number of passive tracers in PTRACERS_SIZE.h
1308    o start to test mnc routinely in exp0
1309    o add sea-ice loading (sIceLoad) as a new forcing field.
1310    
1311    checkpoint54b_post
1312    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1313       impressive on Altix and Opteron systems)
1314    o diagnostics can now write NetCDF files through the mnc package
1315    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1316    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1317    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1318      affects (truncation error) output of lab_sea & natl_box exp.: updated
1319    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1320    
1321    checkpoint54a_post
1322    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1323    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1324    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1325    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1326      + internal_wave (shift in writing cg2d_ini_res)
1327    checkpoint54a_pre
1328    
1329    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1330      - modified verification/lab_sea and natl_box_adjoint accordingly
1331    
1332    checkpoint54
1333    checkpoint53g_post
1334    o prepare splitting of thermodynamics: store convect.counter in common block
1335    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1336      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1337    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1338    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1339    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1340    o restore adjointability
1341    
1342    checkpoint53f_post
1343    o modifications that affect AIM experiment results (update output.txt):
1344      - no advection of S at top interface Nr (pkg/generic_advdiff)
1345      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1346    o AIM pkg:
1347      - include stability function into surf.Flux derivative relative to Tsurf
1348      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1349    
1350    checkpoint53e_post
1351    o merged cylindrical coord configuration
1352    o added rotating_tank experiment
1353    checkpoint53e_pre
1354    
1355    checkpoint53d_post
1356    o faulks upgraded: re-generate output.txt that have changed:
1357       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1358    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1359    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1360    o added Sadourny discretization of Coriolis
1361      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1362      - re-enabled use of omega3 (useAbsVorticity)
1363    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1364      vector-invariant equations
1365      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1366    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1367      hopefully without new bugs
1368      - still to do: biharmonic friction for non-hydrostatic w
1369    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1370    o regenerated output for global_ocean_ebm (using -ieee)
1371    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1372      of mom_common/
1373      - simple re-arrangement of instructions within computing loop
1374    checkpoint53d_pre
1375    
1376    checkpoint53c_post
1377    o new version of coupler for AIM+thSIce and Ocean models
1378     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1379     - land: change Evaporation of snow
1380     - aim with thSIce: fix bug in snow-precip.
1381    o changes to calc_gw.F
1382     - bug fix for w^2 term near the bottom boundary
1383     - (hopefully) improve the lateral slip boundary condtions for use with
1384        partial/looped cells
1385      - because the bug fix changes two verification experiments anyway (exp5
1386        and plume on slope), change the lateral boundary condition from half slip
1387        to the value of no_slip_sides
1388    o ebm package wasnt quite up to the parallel task. Fixed that.
1389    o Adjoint of EBM package + verification
1390      * TLM OK
1391      * ADM not sufficient accuracy yet (needs further testing)
1392    
1393    checkpoint53b_post
1394    o Commiting new energy balance model to repository
1395      * package is pkg/ebm
1396      * verif. is verification/global_ocean_ebm
1397      * references are in ebm_driver.F
1398    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1399    C        Global thermohaline circulation. Part I:
1400    C        Sensitivity to atmospheric moisture transport.
1401    C        J. Climate 12(1), 71-82
1402    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1403    C        Global thermohaline circulation. Part II:
1404    C        Sensitivity with interactive transport.
1405    C        J. Climate 12(1), 83-91
1406    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1407    C        Destabilization of the thermohaline circulation
1408    C        by atmospheric eddy transports.
1409    C        J. Climate 7(12), 1870-1882
1410    o Will need long integration testing.
1411    checkpoint53b_pre
1412    
1413    o created pkg/mom_common in preparation for variable viscosity code
1414    o renamed and split ini_mnc_io
1415    o pkg/land: only liquid water can diffuse or run-off
1416    o AIM using land: soil wetness availability account for snow
1417    o added printMapIncludesZeros to EEPARMS namelist
1418    
1419    checkpoint53a_post
1420    o restore TAMC compatiility for exf_constants.h
1421      (no usage of _d in .h)
1422    o Additional storing in KPP in an attempt to fix
1423      TAMC problem with adjoint of KPP code.
1424      (no success...)
1425      Identical code works fine with TAF.
1426    o Fixed verification/natl_box_adjoint experiments.
1427      Initial conditions for Experiments 4 and 5 are now
1428      set to "SEAICE_initialHEFF=0", which is more reasonable,
1429      and hence gives results closer to that of Experiment 2.
1430      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1431    
1432    checkpoint53
1433    o stable checkpoint with up to date adjoint
1434      TLM tests only run for 1st grdchk at the moment. Its unclear if
1435      this is a code problem or a problem with resetting code for g_
1436      variables that is being autogenerated wrong.
1437      Otherwise:
1438       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1439       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1440         are both still in chaos following their security messes.
1441    
1442    checkpoint52n_post
1443    o various build (mostly genmake2) changes including:
1444      - ability to build/run more easily within Cygwin and MacOS X
1445      - more complicated Makefiles with a stronger dependence on Gnu Make
1446    o pkg/seaice modifications
1447      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1448        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1449        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1450      - changed proxy for geostrophic velocity and updated
1451        verification/lab_sea/results/* accordingly
1452      - removed ADI dynamic solver from pkg/seaice
1453      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1454        they caused a segmentation fault under certain circumstances
1455      - removed unused field WATR
1456    o bug fix in exf-package:
1457      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1458         now reflect that.
1459    o small fixes in the cal-package:
1460      - set reference date to first of January for the 'model'-calendar
1461      - failing of cal_CheckDate in cal_FullDate now actually results in a
1462        warning
1463    o small modifications in exf-package to increase flexibility:
1464      - change climtempfreeze from a constant to a runtime parameter that
1465        is specified in data.exf_clim (default = -1.9)
1466      - introduce runtime parameter windstressmax (default = 2.0) that is
1467        specified in data.exf
1468    o fix in pkg/thsice:
1469      - update Evap (Tsf changes) to be consistent with Latent heat flux
1470      - maintain snow precipitation unchanged (even if Tsf >=0).
1471     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1472    
1473    checkpoint52m_post
1474    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1475      this does not change any of the results, because myIter=0 in swfrac always
1476      lead to jwtype=2 (the default anyway), but the call makes little sense
1477      as a default
1478    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1479    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1480      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1481    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1482    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1483    o extending useSingleCpuIO option to work with new exch2 I/O format
1484      - old-style, missing-tile I/O is still accessible by defining CPP
1485        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1486    o monitor package can write to NetCDF files and/or STDOUT
1487    o fix re-definition bug in MNC_GRID_INIT_ALL()
1488    o doc/api_reference added
1489      - a framework for building an API Reference Manual using all
1490        the "protex" comments embedded in the code
1491      - see pkg/generic_advdiff, pkg/mnc for examples
1492    o MNC:
1493      - make myThid the last argument for all subroutines
1494      - new default for the grid files: NO halos
1495      - add useMNC and other run-time flags
1496      - separate per-file-group handling of the unlimited dimension
1497      - early initialization of MNC w/ flags read at the eeboot stage
1498        and lookup tables set in initialize_fixed
1499      - write all MNC output to a freshly-created directory
1500    o thermodynamics sea-ice (thsice) is now tested with testreport.
1501    o test exp. advect_cs: use the standard cs32 grid ; update output.
1502    o Added functionality to grdchk:
1503      pick global i,j,k position (or nearest wet) where to perform check.
1504    
1505    checkpoint52l_post
1506    o new land formulation:
1507      a) use ground enthalpy as prognostic variable to ensure exact
1508         energy conservation.
1509      b) account for water temperature and for latent heat of freezing
1510         in all processes (rain, run-off, ground storage)
1511      c) compute surface and ground temperature implicitly.
1512    o aim_v23 modification for new land model:
1513      a) Treat separately land / ocean / sea-ice surface fluxes
1514         to allow implicit computation of land & sea-ice surface temp.
1515      b) add snow precipitation.
1516    checkpoint52l_pre
1517    
1518    o fix problem (when 1 tile is empty) in min/max monitor.
1519    o fix bug in timeAve (u,vZetatave in common block)
1520    o no restoring terms under ice for pkg/seaice
1521    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1522    o bug fix for pkg/seaice pickups
1523    o change MNC call locations and add coordinate attributes
1524    o mask vorticity at the corner ; affects global_ocean.cs output
1525    o fix ini_curvilinear_grid ; test CS experiments with mpi
1526    o aim.5l_cs: modify sea-ice fraction input file ; update output
1527    o exf: Adding simple range check routine for exf fields after read
1528    
1529    checkpoint52k_post
1530    o removed top-level directory "diags"
1531      - we migrated these functions to pkg/timeave a long time ago
1532    o fixed bug introduced in pkg/monitor
1533    o accuracy ctrlprec = 32 insuffient for gradient checks using
1534      averaged fields (I/O via cost_averages)
1535      -> use ctrl.h in active_file*.F to control I/O precision.
1536    o paramter list of CALL ADTHE_MAIN_LOOP
1537    o added initial do_the_model_io to ecco
1538    o set all ...Freq to zero after cost_final
1539      taveFreq, dumpFreq, pChkptFreq
1540    o MAIN and ECCO differentiability restored
1541    
1542    checkpoint52j_post
1543    o fix nchklev in tamc.h for global_ocean...
1544    o Bringing flow and store directives up-to-date
1545    o Really weird thing!
1546      call do_the_model_io from the_main_loop with parameters
1547      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1548      TAF places a faulty re-call of initialise_varia
1549      after cost_final call which should not be there!
1550    checkpoint52j_pre
1551    
1552    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1553      error messages
1554    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1555    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1556      debug output
1557    o modfied mdsio_writefield.F to handle non-global files under exch2
1558    o update AIM Cubed-Sphere exp (aim.5l_cs):
1559      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1560    o update AIM Equatorial Channel exp:
1561      use standard aim_v23 pkg and change the SST fields to be more realistic.
1562    o globalFile now works with exch2
1563    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1564      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1565    o limit timeave output for hi-res integrations
1566    
1567    checkpoint52i_post
1568    o removed CPP_EEOPTIONS.h from verification/*/code
1569    o updated the tiling for global_ocean_pressure
1570    checkpoint52i_pre
1571    
1572    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1573      the old pkg/aim).
1574    
1575    checkpoint52h_pre
1576    o shortened offending lines in exch2_send_rx?.template
1577    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1578  o genmake2: add build & execute test for NetCDF code  o genmake2: add build & execute test for NetCDF code
1579  o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed  o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1580    old grid files, moved CPP_EEMACROS.h to pkg/exch2    old grid files, moved CPP_EEMACROS.h to pkg/exch2
