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

1509    o exf: Adding simple range check routine for exf fields after read
1510    
1511    checkpoint52k_post
1512    o removed top-level directory "diags"
1513      - we migrated these functions to pkg/timeave a long time ago
1514    o fixed bug introduced in pkg/monitor
1515    o accuracy ctrlprec = 32 insuffient for gradient checks using
1516      averaged fields (I/O via cost_averages)
1517      -> use ctrl.h in active_file*.F to control I/O precision.
1518    o paramter list of CALL ADTHE_MAIN_LOOP
1519    o added initial do_the_model_io to ecco
1520    o set all ...Freq to zero after cost_final
1521      taveFreq, dumpFreq, pChkptFreq
1522    o MAIN and ECCO differentiability restored
1523    
1524    checkpoint52j_post
1525    o fix nchklev in tamc.h for global_ocean...
1526    o Bringing flow and store directives up-to-date
1527    o Really weird thing!
1528      call do_the_model_io from the_main_loop with parameters
1529      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1530      TAF places a faulty re-call of initialise_varia
1531      after cost_final call which should not be there!
1532    checkpoint52j_pre
1533    
1534    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1535      error messages
1536    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1537    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1538      debug output
1539    o modfied mdsio_writefield.F to handle non-global files under exch2
1540    o update AIM Cubed-Sphere exp (aim.5l_cs):
1541      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1542    o update AIM Equatorial Channel exp:
1543      use standard aim_v23 pkg and change the SST fields to be more realistic.
1544    o globalFile now works with exch2
1545    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1546      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1547    o limit timeave output for hi-res integrations
1548    
1549    checkpoint52i_post
1550    o removed CPP_EEOPTIONS.h from verification/*/code

1552    checkpoint52i_pre
1553    
1554    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1555      the old pkg/aim).
1556    
1557    checkpoint52h_pre
1558    o shortened offending lines in exch2_send_rx?.template
1559    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1560    o genmake2: add build & execute test for NetCDF code
1561    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1562      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1563    o added useSingleCPUIO flag to monitor.F and mon_out.F
1564    o added temporary hack for sea-ice dynamics on the cube:
1565      metric terms are ignored and it is assumed that
1566      there is no sea-ice on cube faces 1, 2, 4, and 5.
1567    
1568    checkpoint52f_post
1569    o added exch2 cube routines to pkg/exch2
1570    o modified hs94.cs-32x32x5 to use it
1571    o added new grid files to hs94.cs-32x32x5
1572    checkpoint52f_pre
1573    
1574    checkpoint52e_post
1575    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1576      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1577    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1578      to work with implicit vertical advection and AB ;
1579    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1580    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1581     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1582    checkpoint52e_pre
1583    
1584    o fix bug in impldiff when Nr=1 or Nr=2.
1585    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1586    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1587    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1588      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1589    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1590    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1591    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1592    
1593    checkpoint52d_post
1594    o re-tiled many expts to allow comparison in multi-processor mode
1595      - updated output accordingly
1596      - changed hs94.128x64x5 to use intial T from file rather than use the
1597        random number generator
1598    o add infrastructure in model routines for fizhi and gridalt packages
1599    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1600    o changes to permit hi-res, cubed-sphere, configuration
1601      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1602      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1603      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1604        of surface winds for the cube
1605      (A verification experiment, based on global_ocean.cs32x15, but with
1606       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1607       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1608       complete with example surface forcing files and matlab scripts to look
1609       at the output and compare it with that of global_ocean.cs32x15.)
1610    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1611       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1612       to conform to the common rule.
1613    o check-in the first version of the coupler + interfaces for multi-components
1614       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1615       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1616       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1617       - ocean and atmos. share the same horizontal grid (no interpolation).
1618       - exchanges between component and coupler is done in forward_step
1619    o new verification experiment, cpl_aim+ocn:
1620       coupled ocean - AIM atmosphere on cs32 grid.
1621    
1622    checkpoint52d_pre
1623    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1624    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1625    
1626    checkpoint52c_post
1627    o Fixing OPTIONS files for use of exf:
1628      - ALLOW_ECCO not needed
1629      - ECCO_CPPOPTIONS.h should not be included from
1630        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1631        as has been the case in the past
1632      - All cal/exf related options are currently set in
1633        single header file. Should remain so until we
1634        agree on a consistent new policy.
1635    o Removed all CPP options for cal package.
1636      cal has no more CPP options.
1637    o modified STOREs in GAD_ADVECTION
1638    o corrected key comp. for passkey
1639    
1640    checkpoint52b_post
1641    o new version: "thsice" of thermodynamic sea-ice pkg:
1642     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1643     - modify fluxes but do not change theta directly;
1644     - light cleaning of bulk_force pkg (still needed with thsice).
1645     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1646       + output_thsice.txt to test thsice & bulk_force pkgs.
1647    o put back grid & coriolis monitor output.
1648    checkpoint52b_pre
1649    
1650    o call "do_the_model_io" at the beginning (=> dump initial state)
1651    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1652    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1653      (need info on NUMBER_OF_PTRACERS)
1654    o missing PTRACERS headers in some routines
1655    o default tamc.h in pkg/autodiff supposed to crash
1656      to ensure proper customization
1657    
1658    checkpoint52a_post
1659    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1660      - moved surfaceTendencyTice from pkg/seaice to main code
1661      - subroutine FREEZE_SURFACE now limits only surface temperature
1662        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1663        => new output.txt for global_ocean.cs32x15 & global_with_exf
1664      - keep the old version of FREEZE for backward compatibility;
1665        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1666      - corresponding modifs for TAF directives
1667    o added surface flux output variables to TIMEAVE_STATVARS
1668    o time-averaged output for pkg/ptracers
1669    o fix problem with ECCO-related divided adjoint
1670      snapshot file was missing some ad-variables,
1671      but no warning issued by TAF
1672    
1673    checkpoint52a_pre
1674    o some bug fixes for #undef REAL4_IS_SLOW
1675    
1676    checkpoint52 = ecco_c52_e35
1677    o after testing adjoints of checkpoint51u_post
1678    
1679    checkpoint51u_post
1680    o this is the post-merge tag of the ecco-branch
1681      (needs another clean checkout and re-testing)
1682    o various natl_box_adjoint configs and results
1683      but no input fields
1684    o obcs adjoint not yet merged!
1685    o adding ECCO global 1x1 and 2x2 degree configs
1686    o updated/extended some store directives for seaice
1687    o pkg/ecco now containes ecco-specific part of cost function
1688    o top level routines the_main_loop, forward_step
1689      supersede those in model/src/
1690      previous input data.cost now in data.ecco
1691      (new namelist ecco_cost_nml)
1692    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1693    
1694    checkpoint51t_post
1695    o this is the pre-merge tag of the ecco-branch
1696    
1697    checkpoint51s_post
1698    o cleanup: removed various obsolete #define-s
1699    o pkg/grdchk
1700      - renamed 'ph-grd 3' to 'grad-res'
1701      - merged from ecco-branch
1702        (remaining bug fixes for obcs gradient checks)
1703      - additional high-precision output for testreport
1704        (grep for 'precision_grdchk_result')
1705    
1706    checkpoint51r_post
1707    o cleaned up or removed CPP_OPTIONS.h files
1708    o updated results for some of the tests to reflect the new
1709      optfiles (-ieee: -O0 instead of -O3)
1710    
1711    checkpoint51q_post
1712    o cd_code:
1713      - moved cd_scheme.F -> cd_code_scheme.F
1714      - separate read_checkpoint from cd_code_ini_vars.F
1715      - separated cd_code part from write_checkpoint
1716      - updated AD_SOURCE, generated .flow
1717      - added CD_CODE_VARS.h to the_main_loop
1718      - Moving cd_code specific store dir.s to pkg/cd_code
1719    o ctrl package totally restructured
1720      - pack/unpack now optional and decoupled from
1721        xx_/adxx_ I/O
1722      - ctrl_pack/unpack cleaned
1723        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1724      - confined inclusion of AD_CONFIG.h to where necessary.
1725    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1726    
1727    checkpoint51p_post
1728    o create initial cd_code package
1729      - WARNING: the initialization of fields within packages
1730        is broken because INI_FIELDS (where READ_CHECKPOINT is
1731        called) is called *before* PACKAGES_INIT_VARIABLES.
1732        This seems to be backwards since
1733        1) its important to initially zero the entire field including
1734           the "halo" region
1735        2) zeroing needs to be done *before* reading pickup info
1736           and the pickup call might or might not happen in any
1737           particular run
1738      - this needs an overhaul for R2
1739    o cleanup verification/*/code/GMREDI_OPTIONS.h
1740    o cleanup testreport
1741    
1742    checkpoint51o_post
1743    o bringing AD-related verif's up to date with genmake2
1744      - carbon/
1745      - global_ocean.90x40x15/
1746      - hs.94.1x64x5/
1747      - (front_relax/ )
1748    o (more) consistent directory structure for AD-related verif.'s
1749    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
1750    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1751    o bug fix in find_alpha.F for MDJWF:
1752      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1753        change rho -> rho-rhoConst
1754      - replace call find_rho to find_rhonum
1755    o initialisation of rFlx extended to full array (required by TAF)
1756      and shifted to thermodynamics
1757    o removed PTRACERS.h in ptracers routine
1758    o added surfacetendencyPtr to S/R parameter list pracers_forcing
1759    o Correcting initialisations for fVerU, fVerV.
1760    o helping TAF to recognize dependency on kUp for
1761      fVerU, fVerV
1762    o Replacing delZ by delR in pkg/ctrl/
1763    checkpoint51o_pre
1764    
1765    o undid all of cp51 pending some cleanups and discussion
1766    o added the [#include "AD_CONFIG.h"] statement to all files that need
1767       it for adjoint/tl #defines
1768     o re-worked the build logic in genmake2 to support AD_CONFIG.h
1769     o removed tools/genmake since it no longer works
1770    
1771  checkpoint51n_post  checkpoint51n_post
