4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
7      changed exf_set_gen.F so that
8        genperiod=0 means input file is one time-constant field and
9        genperiod=-12 means input file contains 12 monthly means
10    o CG2D: use pre-computed solver main-diagonal (stored in common block);
11      this affects truncation error ; generate new output file for exp. which
12      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
13        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
14        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
15        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
16        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
17        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
18    o start implementation of deep-atmosphere and anelastic formulation
19    o verification: remove 2nd copy of input files and use script "prepare_run"
20      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
21    o mom_common/vecinv/fluxform: fix a few initialisation isssues
22    o profiles: fix for multithreaded case
23    
24  untagged  o diagnostics: rename few diags:
25      s/'PRESSURE'/'RCENTER '/g
26      s/'TICE    '/'oceFreez'/g
27      s/'TAUX    '/'oceTAUX '/g
28      s/'TAUY    '/'oceTAUY '/g
29      s/'SWFLUX  '/'oceQsw  '/g
30      s/DIFx/DFxE/g
31      s/DIFy/DFyE/g
32      and add few ocean-forcing diagnostics:
33      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
34    o modifications to pkg/seaice/growth.F and budget.F, which change results of
35      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
36      as actual snow thickness.  It now refers everywhere to effective snow
37      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
38    
39    checkpoint58r_post
40    o modifications to pkg/seaice/growth.F, which change results of
41      lab_sea experiment: fixes pertain to melting snow over open water, to
42      masking EVAP under sea ice, and to using the correct AREA variable for
43      computations of EVAP, PRECIP, HSNOW, and GHEFF
44    o add ability to read bathy, salt, and theta using MNC (off by def)
45    o add flooding algorithm and advection of HSNOW for pkg/seaice;
46      both are turned off by default and do no change any results
47    o seaice advection with pkg/thsice: a step toward the use of non-linear
48      advection scheme, but #ifdef or commented out for now (requires more EXCH).
49    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
50      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
51      in natl_box (affects results @ truncation level: update output.txt)
52    o multi-threading and IO:
53      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
54      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
55        (needed to work with SingleCpuIO): tested in all verif. exp.
56    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
57      affects the results (but none of the verification test uses this scheme).
58    o Adding some pkg/diagnostics capability to pkg/seaice
59      (will certainly be subject to changes)
60    o ctrl: adding new control variables:
61      lwflux, lwdown, evap, snowprecip, apressure, runoff
62    
63    checkpoint58q_post
64    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
65      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
66      high_res_cube configuration by 4% on Columbia.
67    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
68      add (in global_with_exf/code) a version of EXF_INTERP_READ without
69      dynamical allocation (seems to work in multi-threaded).
70    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
71      single CPU io) so that TAF does not have to see EESUPPORT.h
72    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
73    
74    checkpoint58p_post
75    o obcs: stop if obcs is used with useCDscheme = .true.
76    o shelfice:
77     - fix a sign error so that no slip at shelfice interface works
78     - remove stop for combination non-hydrostatic code and shelfice. That does
79       not mean, that the results are correct, but at least they are numerically
80       stable
81    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
82    o added adjoint exch routined for all exch*3d* routines
83      and updated flow directives
84    
85    checkpoint58o_post
86    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
87      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
88    o change controling S/R for writing pickup file (new S/R do_write_pickup)
89      and clean-up reading/writing of pickup files.
90    o fix local version of read/write pickup (NH part) in rotating_tank/code
91    o simplify EXCH interface:
92     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
93     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
94    o added the regrid package
95    o shelfice:
96     - add a simple boundary layer scheme to reduce noise
97     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
98    
99    checkpoint58n_post
100    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
101       local variable (not in common block).
102    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
103      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
104      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
105        to work with SingleCpuIO.
106    o add "_d 0" to real constant of pkg/cfc subroutines ;
107       update exp. cfc_exemple & tutorial_cfc_offline output files.
108    o multi-threading and IO:
109      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
110        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
111      - barrier before and after reading.
112      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
113      - avoid using MDS_WRITELOCAL for LAND pkg output.
114      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
115        common-block variables ; Allows multi-threading with master-thread IO.
116    o change default MAX_NO_THREADS from 32 to 4 ;
117      and stop cleanly when MAX_NO_THREADS is too small.
118    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
119    
120    checkpoint58m_post
121    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
122       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
123    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
124       keep global_ocean.90x40x15 (for AD testing) with former secondary test
125       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
126    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
127        add MITgcm_tutorials (= code + all the tutorials)
128    o ecco, option to compute cost for total ssh (mean+anom)
129    o consistent with addition of ptracer and ssh in pkg/profiles
130    o profiles: adding ptracer and ssh
131    o testreport: change multi-test output-file name
132      (from output.txt.{name} to output.{name}.txt)
133    o profiles: now ok for mutli-tiles case
134    o seaice: add 4 parameters for different advection schemes for area,
135      (effective) seaice thickness, enthalphy, and snow height. Their default
136      is the standard parameter SEAICEadvScheme
137    o calc_gw:
138     - add cosFacU in zonal viscous flux (harmonic.visc.).
139     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
140       of tutorial_plume_on_slope.
141    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
142    o calc_gw: true flux-form, account for horizontal grid spacing.
143      update rotating_tank results, but not plume_on_slope (affected at
144      truncation level, 11 digits).
145    
146    checkpoint58l_post
147    o calc_gw:
148     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
149     - remove side-drag for now (need to fix it); update plume_on_slope results.
150     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
151    o commit code to make SST/SSS weights spatially variable
152      (based on either variable in-situ or variable initial T/S weights)
153    o pkg/ecco:
154      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
155        now based on horizontally varying weights wthetaLev, wsaltLev
156      * cost_averagesflags now returns year indices in addition to day, month
157      * sflux balance is performed on annual basis
158        (sflxumm, sfluxmm2, bal_sfluxmm)
159      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
160        including separate counting and multipliers
161    o pkg/rbcs
162      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
163    
164    checkpoint58k_post
165    o testreport:
166     - always build in dir. "build" (if not there, mkdir build instead of building
167       & running in input)
168     - run in dir run (if it exists), in build otherwise.
169     - call prepare_run (if input/prepare_run exists)
170     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
171    o pkg/exf modifications to interpolation and rotation routines for more
172       reasonable treatment of North Pole singularity: for tracers North Pole
173       value is set to northernmost zonal-mean value, for zonal velocity it is
174       set to zero, and for meridional velocity it is set to northernmost value.
175    o pkg/exf/exf_check_range.F
176     - add tile index to diagnostics and move stop statement to the very
177       end of the routine.
178    o pkg/diagnostics: (diagnostics_main_init.F)
179      define title of isomorphic variables according to the current config.
180    o pkg/thsice with pkg/seaice dynamics:
181    - fix domain of computation (interior only, required for exf) and do exchanges
182    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
183    o towards a standard way of dealing with multi-threading in MONITOR
184      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
185    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
186       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
187    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
188    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
189    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
190       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
191    o tracer advection:
192     - clean-up and simplify calc_common_factors.F
193     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
194       advection subroutine (but still not used within DST advection S/R)
195    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
196    
197    checkpoint58j_post
198    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
199      from file (collects calls previously in FORWARD_STEP)
200    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
201    o adjoint store dir. adjusted accordingly
202    o genmake2
203      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
204    
205    checkpoint58i_post
206    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
207      on wind stress (SEAICEstressFactor defaults to 1.)
208    o Total number of Timers is finite (<=40): comment out 2 non-essential one
209      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
210    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
211      on CS-grid: no longer loosing mass.
212    o exf & curvilinear-grid: no longer modify longitude xC & xG.
213    o pkg/ggl90: fix sloppy output and fix a bug
214    o pkg/seaice: added SEAICEuseEVPpickup parameter
215      - Set to false in order to start EVP solver with
216        non-EVP pickup files when using SEAICEuseEVP
217      - fix sign error in diffusion in seaice_calc_rhs
218    
219    checkpoint58h_post
220    * Modifications for bottom topography control
221      o replace hFacC by _hFacC at various places
222      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
223      o add non-self-adjoint cg2d_nsa
224      o update autodiff support routines
225      o re-initialise hfac after ctrl_depth_ini
226      o works for 5x5 box, doesnt work for global_ocean.90x40x15
227    * Adding verification for 5x5 box (4-layer) bottom topography control
228    
229    checkpoint58g_post
230    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
231       used for mean seasonal cycle, mean diurnal cycle); add an example
232       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
233    o pkg/ggl90:
234      - add parameter (minimum surface kinetic energy)
235      - fix bug (avoiding division by zero)
236    o couple pkg/thsice to pkg/seaice:
237      - modify advection in seaice to accomodate new scalar fields to be advected
238      - only muliDimAdection scheme work with seaice/thsice
239      - mapping of thsice-variables to seaice-variables, back and forth
240      - does not break the verification experiments, but does not give the
241        desired results either
242    o pkg/seaice
243      - make (default) second order advection a bit less confusing?
244    
245    checkpoint58f_post
246    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
247      to pkg/seaice):
248      - new routines thsice_map_exf and thsice_get_exf provide the interface
249      - add an additional formal parameter to thsice_solve4temp
250    o pkg/exf:
251      - add new fields wspeed, snowprecip (to be able to couple to thsice)
252      - correct Stefan-Boltzmann constant
253      - new parameter for longwave surface emittance
254      - separate some stuff from exf_bulkformulae into new routines  
255        exf_radiation, exf_wind
256      - add new parameters and constants: longwave emissivity for ocean, ice
257        and snow, evaporation parameters over ice
258      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
259        either wind from stress or stress from wind
260    o pkg/thSIce:
261    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
262    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
263       and THSICE_CALC_THICKN
264    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
265    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
266      to make debugging easier.
267    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
268    o pkg/bulk_force:
269      - clean-up comments and parameters ;
270      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
271    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
272      generate new output for test-experiment: aim.5l_cs.thSI
273    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
274      testreport accordingly
275    
276    checkpoint58e_post
277    o SEAICE_CGRID adjoint done
278    o R_STAR adjoint implemented.
279      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
280      * need to sort out init. of h0facc, etc.
281    o Make pkg/profile fully independent of ecco,cost, etc. stuff
282      to be able to use it in pure forward.
283    
284    checkpoint58d_post
285    o upgrade simple test-experiment to tutorial example:
286     step.1: duplicate the experiment and (step.2) will remove the old copy.
287      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
288      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
289      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
290      tutorial_global_oce_biogeo    <- copy of dic_example
291      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
292      tutorial_plume_on_slope       <- copy of plume_on_slope
293      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
294      tutorial_global_oce_optim     <- empty for now (David ?)
295      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
296     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
297    o correct a sign problem in cost_scat.F
298    o obcs and ptracers: fix boundary conditions for advections schemes
299      with larger stencil
300    o thsice adjoint: start
301    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
302      completeness
303    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
304      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
305    o ptracers adjoint:
306      * avoid extensive recomputatations
307      * fix missing re-init. of gptr (missed by TAF)
308    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
309      me to turn off the excessive output to STDOUT that this package produces
310    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
311      and add those terms in Vector-Invariant formulation.
312    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
313      if the control period (xx_hfluxperiod etc) is 0
314    o in profiles pkg, clean routines and fix details
315    o in ecco pkg, reading ssh data:
316      fix problem in case the model does not start at iter0=0
317    o fix mnc-pickup/restart for ptracers
318    o new package prifiles:
319      code to compute profile-based cost by Gael Forget
320      (modifs in ecco, ctrl, autodiff)
321    o Benign bug fix in initialization (spotted by M. Mazloff) of
322      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
323    
324    checkpoint58c_post
325    o adjoint: finish NLFS adjoint and provide reference output in
326      verification/global_ocean.90x40x15/results_ad_nlfs
327    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
328      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
329      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
330      with SEAICE_CGRID defined.
331    o move calendarDumps from "data" to "data.cal" and clean-up the code
332      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
333    o add useEXF & useCAL flags (for now, set in hard-coded way)
334    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
335      (were missing in NH mode, and wrong in quasihydrostatic mode).
336      waiting for Chris updated version of calc_gw to add those CALLs.
337    o fix bug in quasihydrostatic S/R ;
338      add a test for this option: global_ocean.90x40x15.qshyd
339    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
340      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
341    o add on/off flag useOffLine for package OFFLINE
342    o seaice:
343      - modify advection so that it works also on the C-grid
344      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
345        problem in multi-tile runs with C-grid
346      - add flags for clipping ice velocities and/or masking solver forcing
347      - fix drag (ocean on ice) formulation and a bug that caused noise in the
348        C-grid solver
349      - added a few comments to seaice_diffusion.F
350      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
351        are now exclusive)
352      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
353        required re-ordering the code a little:
354       + make DAIRN global variable (defined in SEAICE)
355       + move computation of the viscosities eta and zeta into a new separate
356         routine (because I need to recompute them in seaice_ocean_stress.F)
357    
358    checkpoint58b_post
359    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
360      update output.txt of exp. aim.5l_cs.thSI
361    o various mnc cleanups and improvements:
362      + shrink lookup tables by factor of ~4
363      + better error reporting when running out of lookup space
364      + able to handle longer path/file names (up to 500 chars)
365    o adjoint:
366      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
367      - TBD: "hidden" mom_vecinv recomp. in dynamics
368    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
369     (allow to differentiate between forcing components using new integer flags:
370      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
371     and add new flag to put Dissipation tendency out of Adams-Bashforth.
372    o ecco
373      - enable trend removal from SSH anomaly obs.
374    o adjoint
375      - a fix for PmEpR when #undef EXACT_CONSERV
376      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
377      - try to fix "hidden" recomp. in forward_step for NLFS
378        (NLFS seems broken sometimes after I checked it in)
379    o seaice:
380     - add c-grid version of the dynamic solver:
381       + three new routines that are the c-grid substitute lsr, dynsolver
382         and ostres
383       + put a few fields that were local to dynsolver into global common
384         blocks, so that I can move the computation of stresses etc into
385         seaice_lsr (saves coding but may break the adjoint).
386     - replace more hardwired parameters by runtime parameters
387     - add ice masks that mask the rhs of the implicit solvers where there
388       is no ice (commented out in seaice_dynsolver, because i am not sure
389       if this works properly), eventually this should replace the clipping
390       of ice velocities in seaice_dynsolver to +/-40cm/s.
391    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
392      include it only where its needed
393    o move balancing of fluxes before the call of external_forcing_surf
394    o seaice:
395      - correct units of turning angles (now they are really in degrees)
396      - move computation of GWATX/Y out of main routine into dynsolver
397      - initialize GWATX/Y in seaice_init
398    o Apply mask on Fresh-Water flux (needed for SSH forcing).
399      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
400    o seaice: add runtime flags for turning angles (default to zero)
401    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
402      and trend from exf forcing and ctrl control adjustments
403    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
404      (since checkpoint57x_post)
405    o change the default rotation period to 86164.s = the Earth rotation
406    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
407      and based on a reference stratification. Tested within hs94.cs-32x32x5.
408    o seaice advection: add code for choosing between the default (2nd order
409      central differences) and multiDim advection schemes provided by
410      pkg/generic_advdiff
411    o seaice:
412      - removed all references to SEAICE_GRID.h fields from
413        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
414        (cubed-sphere configuration will change a little)
415      - grid computations in seaice_init are obsolete now.
416      - cleaned up code a little so that is easier to read (hopefully).
417      - added new (better?) discretizations of default advection and diffusion
418        (turn on with SEAICEuseFluxForm)
419      - replace 1 in 3d global fields by kSurface in growth.F
420      
421    checkpoint58a_post
422    o seaice:
423      - bug fix in advect.F
424    o shelfice:
425      - separate shelfice load anomaly from pload (breaks with time
426        dependent forcing), => introduce constant field shelficeLoadAnomaly.
427        Its default is 0., but it may be computed more cleverly from (unknown)
428        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
429        done offline. A good approximation of the pressure load anomaly is
430        necessary to avoid large initial adjustment processes underneath
431        deep-reaching shelfice.
432      - small fix in ISOMIP shelfice_thermodynamics
433      - add more sophisticated thermodynamics of Hellmer (1989), this is
434        now the default
435      - give a few constants more intuitive names
436    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
437      if bulk formulae are used in long integration (especially EmPmR). Turn
438      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
439      if balancePrintMean, the imbalance that is substracted is printed to
440      STDOUT.
441    o fix bug (typo) in obcs_apply_eta.F
442    o add a new package shelfice which enables us to model the circulation
443      underneath shelf-ice with draughts of hundreds of meters.
444     - works
445     - to do: + include improved thermodynamics
446              + check whether kSurfC (from model/inc/SURFACE.h) can be used
447                instead of new field kTopC
448              + can we use topoFile, Ro_surf and existing code in ini_depth.F
449                instead of new field R_shelfIce and new code in ini_depth.F
450                and ini_mask_etc.F?
451              + adjust vertical mixing schemes?
452    o seaice pkg:
453     - add a cpp-flag to include a simple formula for a salinity dependent
454       freezing point of sea water at the surface
455     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
456       meridional stresses are now different (and hopefully correct)
457    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
458       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
459       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
460    o pkg/diagnostics: add options and parameters for regional-statistics
461       diagnostics ; define regions by reading a region-mask from a file
462       (might add other options later)
463    o pkg/bulk_force:
464     - add option and parameters to use AIM surface-flux formulae.
465     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
466       others forcing fields (defined in PARM05, parameter file "data") are loaded
467       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
468     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
469     - use the right EXCH call for uwind,vwind (to work on CS-grid).
470     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
471       and parameters (note: calcWindStress replaces .NOT.readwindstress).
472     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
473    
474    checkpoint58
475    o add "--embed-source" option to genmake2 which, when the supporting
476      tools can be compiled (as determined by genmake2) will turn on the
477      embed_files package which then embeds the entire MITgcm source code
478      (*.[fFhc] + Makefile) used for the build within the executable
479      - requested by CNH but off by default
480      - adds a paltry <9MB to the mitgcmuv executable in most cases
481      - only writes the output when useEMBEDSRC in eedata is true
482    o clean up 3-dim. relaxation codes:
483      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
484      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
485      * Thanks to Tom Haine for testing!
486    
487    checkpoint57z_post
488    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
489      affects output (@ truncation level) of exp. plume_on_slope ; updated.
490    o fix the pickup behavior for obcs in combination with ptracers
491    o fix a bug in ptracers_external_fields_load
492    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
493      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
494    o transfered surface NH pressure to eta field (if exactConserv).
495    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
496         and update lab_sea output.txt file.
497    o completing 3-dim. relaxation code: additional term
498         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
499      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
500      * At compile time, in "EXF_OPTIONS.h" set
501          #define  ALLOW_CLIMTEMP_RELAXATION
502          #define  ALLOW_CLIMSALT_RELAXATION
503      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
504          tauThetaClimRelax3Dim = 15552000.0,
505          tauSaltClimRelax3Dim  = 15552000.0,
506      * 3 cases:
507          1) Use a constant-in-time 3-dim. field
508          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
509          3) Real-time relax. to time-evolving prescribed field
510    o Adding Laplacian-type smoothness constraint on
511      initial and boundary (forcing) controls (ic, bc)
512      * enable at compile-time via
513        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
514      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
515      * Absolute scale somewhat unclear so far
516      * no area weighting was included since no other cost term does so far
517    
518    checkpoint57y_post
519    First step for a NLFS adjoint
520    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
521    o new init. routines for calc_r_star, calc_surf_dr
522    o still need to deal with ini_masks_etc
523    o testreport seemed happy
524    checkpoint57y_pre
525    
526    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
527    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
528    o add new offset feature to offline pkg (plus minor cleanup)
529    o cfc fixes for final year of integration
530    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
531      be in GCHEM_OPTIONS).
532    
533    checkpoint57x_post
534    o fix testreport Pb in multiple test experiment.
535    o cleanup our namelist syntax in verification:
536      - make it more F95 standards compliant (some work still needed)
537      - allows the vast majority of our tests to work with gfortran
538    o Non-Hydrostatic:
539     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
540     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
541    o Allow to apply AB on T,S rather than on AB(gT,gS):
542     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
543     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
544       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
545     - need a "clever" read_pickup to restart from the other AB formulation
546    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
547    o remove some unused variables (reduces number of compiler warnings)
548    o adjoint
549      * Disable useVariableViscosity for adjoint for time being
550        (there are a number of extensive recomputations)
551      * Initialize certain variables needed for adjoint
552    
553    checkpoint57w_post
554    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
555                 fix the singleCpuIO RS version of MDSWRITEFIELD
556       and add a WARNING if using globalFiles=T with multi-processors.
557    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
558      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
559    o tracer advection scheme:
560      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
561       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
562       was not very convenient).
563      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
564       (further tests needed for the implicit DST & Flux-Limiter schemes).
565    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
566      and sRef for convenience, handy, when you want to initialize
567      ptracers in a large domain with a constant non-zero value. Also,
568      untangle ptracers_init.F a little.
569    
570    checkpoint57v_post
571    o change dome exp. to use variable viscosity in side-drag terms.
572    o remove all the files from the cfc_offline test since they are now
573      incorporated into tutorial_cfc_offline which has been producing
574      identical results for a few days of testing
575    o add new parameter: sideDragFactor to enable half-slip-side BC
576      and change side-drag S/R to use viscosity from mom_calc_visc
577      (can switch back by setting sideDragFactor=0.); affects results at
578      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
579       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
580    o vorticity & strain are now computed without masking, to account for
581      no-slip-side BC in variable viscosity calculation ; mask is applied
582      anyway later on, before computing advection/coriolis terms.
583    o modify exp4 to test new obcs support for reading from external files
584      and for passive tracers
585    o fix behavior of ptracers_monitor when monitor output is written to a
586      netcdf-file; still not independent of monitor.F (writes in the same
587      file).
588    o change default value of tRef (put a uniform, meaningful value for ocean
589      & atmos) and initialize sRef (was missing, as Martin mentioned).
590    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
591      to be proportional to enstrophy dissipation length.  Thus,
592       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
593      This is now consistent with Smagorinsky and with the manual.
594    
595    checkpoint57u_post
596    o OBCS and PTRACERS: add open boundary support for passive tracers
597      - either use homogenous (pseudo) v.Neumann conditions or prescribe
598        OB-values from file; this is not different from the way theta and salinity
599        are treated
600      - however, Orlanski-radiation conditions are not supported, and the model
601        will stop if you use pTracers and Orlanski at the same time.
602      - beefed up the rountine obcs_external_fields_load: now only those open
603        boundary values are overwritten with values from files for which there
604        are really files, otherwise the OB-fields remain untouched. This makes
605        it possible to use different OBs at different ends of the domain (as
606        with EXF)
607    o reduce number of exch calls in shap_filt (s2).
608    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
609      truncation level) 4/5 MLAdjust test results (11&12 digits match).
610    
611    checkpoint57t_post
612    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
613    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
614      same truncation, independent of the face number: affects affects several
615      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
616    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
617      note that biharmonic viscosity + no-slip was not tested in any experiment.
618    o fix bug in non-linear free-surf side-drag ; generate new output for
619      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
620    o make mnc honor the writeBinaryPrec flag for most kinds of output
621    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
622    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
623      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
624    o add brackets in multi-terms sum to get same truncation, independent of
625      the face number (manage to get exactly same value of gU,gV at the cs-edge)
626      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
627    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
628      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
629      a maximum grid-scale Reynolds number.  Also, changes all length calculations
630      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
631      Suggested values of viscosity parameters found in mom_calc_visc.
632      Many new viscosity diagnostics available.
633    
634    checkpoint57s_post
635    o Add clearing-house for viscosity calculations, mom_calc_visc and
636      correct numerous bugs in LeithD and Smagorinsky discretizations.  
637      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
638      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
639      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
640      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
641      The Strain-Tension form is now called with useStrainTensonVisc=.true.
642      ViscAhStrain and viscAhTension are now retired.
643    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
644    o In response to JMC's bug report, genmake2 now ignores any soft-links
645      that it finds in the *current* directory when searching for files.
646      Soft-links found in any other source directories will still work as
647      they did before.
648    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
649      a C routine to unlimit the stack size
650    o mnc-ify pkg/aim snapshot vars
651    o mnc-ify pkg/land as requested by Daniel
652    o various changes to mnc including:
653      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
654      - output can now be grouped so that all files within a group
655          change the ITER portion of their names in lock-step together
656      - can now read ("global") PER-FACE (in addition to PER-TILE) files
657          and works with both EXCH1 and EXCH2 (but needs more testing)
658      - writing works for all verification test cases w/ g77 on Linux
659    
660    checkpoint57r_post
661    o make MNC variable initialization happen earlier
662    o add diagnostics for (almost) each term of the momentum Eq.
663    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
664    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
665    o remove MINIMAL_TAVE_OUTPUT option ;
666      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
667    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
668      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
669    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
670    o add time-dependent SST, SSS control
671    o cost terms in ecco/ modularized (new cost_generic.F)
672    o cost_averages routines are modularized (new cost_averagesgeneric.F)
673    o new infrastructure for seaice model vs. obs misfits in seaice/
674      * driver from the_main_loop.F is seaice_cost_driver.F
675      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
676      * gradient check in Exp. 6a of natl_box_adjoint/
677    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
678      (see README file)
679    
680    checkpoint57q_post
681    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
682    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
683      - bug was reported by Jean-Michel and Ian Fenty
684    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
685      update exp. cpl_aim+ocn output.
686    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
687      Needed for high-res. runs with large global files
688      to be able to limit tapelev size
689    o Changed some tests for adjoint:
690      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
691      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
692      * global_ocean.90x40x15/ back to default 3-level checkpointing
693    o Modifications to enable scripted COMMON to MODULE conversion
694      * verification/OpenAD/code/ has necessary scripts and description;
695      * converts, compiles and runs successfully;
696    
697    checkpoint57p_post
698    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
699    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
700      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
701    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
702    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
703      (was already the case for dissipation with mom_vecinv,
704       and also the case for grad.PhiHyd when staggered-timeStep)
705      This will allow to put dissipation out-off the AB time-stepping.
706     Unfortunately, affects truncation error. Update output of exp. that "fails"
707      (cg2d matching number) and leave the others for later: front_relax(10),
708      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
709      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
710    
711    checkpoint57o_post
712    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
713      (2) its ready to be documented during the 20050801 DocFest
714    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
715      for ideal_2D_oce and lab_sea on linux_ia32_g77
716    o set to #undef CTRL_SET_OLD_MAXCVARS_30
717      in global1x1_tot/code_seaice_adj to access indices 32, 33
718      (worth another tag)
719    
720    checkpoint57n_post
721    o adding precip control xx_precip 32
722    o adding swflux control xx_swflux 33
723    o Replacing 10 forcing penalty cost routines by 1 generic.
724    o Implementing partitioning in time-mean and variable adjustment
725      for atmos. state.
726    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
727    o in natl_box_adjoint:
728      * updated exp 1 to 10
729        (but does not have time-mean vs. variable split results yet)
730    o updated global1x1/*_seaice_adj/
731      to incorporate latest changes
732    o enable useSingleCpuIO for mdsio vector routines
733      (applies in particular to tapelev I/O)
734    o removed inefficient K-loop in all active_file*control*.F
735    
736    checkpoint57m_post
737    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
738      and advect_cs (use EXCH-2 and standard cs-32 grid files).
739    o pkg/exch2: filling of face-corner halo regions is optional
740      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
741    
742    checkpoint57l_post
743     tag before updating tutorials (pre-release-2)
744    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
745       for output and interpolation of input fields onto model grid)
746    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
747       Affects results of exp. rotating_tank ; update output.txt.
748    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
749          and taking the square quantity and/or using a fraction-weight field.
750    o fix aim_diagnostics_init.F mate numbers.
751    o add mnc output capability to diagnostics/diagstat and update
752      our cvsignore files for the ACSII output generated
753    
754    checkpoint57k_post
755    o lab_sea now uses diagnostics package and provides a suite of
756      new EXF diagnostics output.
757    
758    checkpoint57j_post
759    o exf
760      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
761        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
762        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
763      * extended diagnostics output
764        - now includes all EXF variables
765        - hs, hl moved to common block
766        - separate S/R for diagnostics, called after ctrl vector is added
767        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
768        - EXFqnet contains true Qnet (i.e. includes qsw)
769      * updated verif. lab_sea, global_with_exf
770      * Rearranging hflux (exf_mapfields -> exf_getforcing)
771        to ensure that diagnostics sees a true EXFqnet
772    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
773    o diagnostics pkg: change pointers so that 1 diagnostic can be used
774      several times with different frequencies.
775    o mnc-ify the thsice package as requested by Daniel Enderton
776      - the monitor--MNC output needs work
777      - many attributes need to be added (most are currently blank)
778    o mnc-ify theaim_v23 package as requested by Daniel Enderton
779      - many attributes need to be added (most are currently blank)
780    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
781    o add Sadourny like discretization to the 4th.O vorticity advection scheme
782    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
783      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
784         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
785    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
786     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
787    
788    checkpoint57i_post
789    o Diagnostics package was changed: diagnostic allocation is now deactivated
790      by setting an empty file name in the namelist (used to be by setting 0 frequency)
791    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
792      add 1rst Order upwind vertical Shear.
793    o add a quick fix for A/B checkpointing in OFFLINE mode
794    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
795      end-run around the C/Fortran linking horror in eesup/src/timers.F
796    o added pkg/runclock: allows user to terminate run based on wall clock
797    o added non-hydrostatic scaling parameter: nh_am2
798    o pkg/my82: futile attempt to make results compiler-independent by adding
799      some "_d 0", etc. no effect.
800    o for mnc output, fill the 'T' coordinate var with myTime and create a
801      separate 'iter' variable for iteration count
802    o pkg/diagnostics:
803      add new capability: output of Global/Regional & per-level statistics ;
804      tested against monitor output (including land & thSIce) on various exp.
805    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
806    
807    checkpoint57h_done
808      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
809      data.diagnostics, data.gchem, data.ptracers) is done.
810    
811    o pkg/diagnostics: prepare for Global/Regional statistics.
812      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
813    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
814      and rename it: DIFFERENT_MULTIPLE
815    
816    checkpoint57h_post
817    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
818    o pkg/diagnostics: change output frequency, now in seconds (instead
819      of Nb of iterations). This requires to change data.diagnostics.
820    checkpoint57h_pre
821    
822    o in mnc, let the user create the output dir if both mnc_outdir_date
823      and mnc_outdir_num are false
824    o add fflags() to pkg/diagnostics which allows one to specify, on a
825      per-file basis, the file precision [default behavior is unchanged]
826    o added diagnostics to pkg/kpp, including computation of mixed layer
827      depth based on a temperature/density criterion
828    o updated verification/natl_box to test the new pkg/kpp diagnostics
829    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
830    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
831    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
832      not mnc -- this mistake was found by JMC and is now corrected
833    
834    checkpoint57g_post
835    o add Adams-Bashforth 3rd Order time stepping:
836      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
837      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
838    checkpoint57g_pre
839    
840    o make lambda[Theta,Salt]ClimRelax spatially varying
841      (default remains spatially uniform constant based on tau)
842    o added new control variables
843      * init. uVel, vVel, etanN
844      * lambda[Theta,Salt]ClimRelax
845    o separate masks used for ctrl_pack/unpack 'from write_grid' output
846      (suggested by G. Forget)
847    
848    checkpoint57f_post
849    o add parameter "baseTime" = model base time = time at iteration zero
850      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
851      account for baseTime shift
852    o move Coriolis arrays from PARAMS.h to GRID.h
853    checkpoint57f_pre
854    
855    o mnc-ifying the seaice package
856    o introduced an alternative length scale calculation for use in the limiting
857      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
858    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
859    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
860      as well as grad(vort3).  Made it compatible with both approximate form
861      for the cubed sphere and full form of these gradients.  Added flag
862      useFullLeith to select between approximate and full form.  
863    o add "d0" in getcon.F to reduce differences between compilers/platforms
864      update output.txt of exp. fizhi-gridalt-hs
865    o change port_rand funtion to allow to set the seed.
866    o fix obscure MNC bug involving conversion between reals and integers
867      - it caused no problems with certain (eg. gcc, ifc) compilers but the
868        new version is now more standards-compliant
869    o adjoint-related modifications
870      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
871      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
872      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
873    
874    checkpoint57e_post
875    o Adding eddy stress controls a la Ferreira et al.
876    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
877    
878    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
879      update output.txt of exp. fizhi-gridalt-hs
880    o add more "Z" dimensions and associated coordinate vars to MNC
881    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
882    o parameter calendarDumps: when set, approximate months (30-31 days) and years
883      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
884      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
885      months and years.  Requires pkg/cal.
886    o diagnostics: add pickup functionality
887      - off by default for backwards compatibility
888      - current version only uses MDSIO -- MNC will be added
889    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
890    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
891    
892    checkpoint57d_post
893    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
894    o modify verification/ideal_2D_oce so that it tests the creation of mnc
895      output from the diagnostics package
896    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
897    o make genmake2 more portable by using ".$FS" instead of ".f" for more
898      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
899    o add coordinate variables to the MNC output from the diagnostics package
900    o change MNC-flags default value: true when useMNC=TRUE
901    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
902      the ability (off by default) to read the grid information using MNC
903    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
904    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
905    o do snap-shot diagnostics at the middle of the time-interval (instead of
906      at the end).
907    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
908      new test for AIM with thSIce + slab-ocean
909    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
910    o move state variable diagnostics to the beginning of the time step ;
911      (note: still needs some work specially for snap-shot diagnostics)
912      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
913    
914    checkpoint57c_post
915    o Change testing option (-ieee) to get closer agreement between g77 & ifort
916    o generate new output.txt files on faulks with g77 & the new -ieee option
917    checkpoint57c_pre
918    
919    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
920      update output.txt of exp. global_ocean.90x40x15
921    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
922      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
923    o add saltFlux(+File) forcing capability with periodicExternalForcing
924    o allow to use pkg diagnostics for GM-Redi & ThSIce output
925    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
926    o improvements for the MNC output from DIAGNOSTICS:
927      - correct handling of the unlimitied dimension
928      - all dims now have associated coordinate variables
929      - variables located at U, V, and Corner ("Z") points are now written
930        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
931        *all* data points are output
932    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
933    o added pkg/seaice/seaice_monitor.F
934    o mdsio_readfield.F can now read files visible only to master MPI process.
935    o pkg/seaice: some test code for ice-modified ocean stress
936    o exf_getffields interpolation defaults to bilinear for all scalar forcing
937      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
938      spurious negative numbers for precipitation and humidity.  Will cause
939      some small numerical differences for integrations using pkg/exf/exf_interp.F.
940    o pkg/ctrl/
941      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
942        May be enabled via doPackDiag
943      *  introduce z-scaling of
944         + gradient (doZscalePack) and
945         + control (doZscaleUnpack)
946    o pkg/mdsio/
947      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
948      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
949    
950    checkpoint57b_post
951    o simplify options in diagnostics_fill arguments (remove weird combinations)
952    o fix MNC coordinate variables so that they now contain per-face index
953      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
954      general, EXCH2 grids are only aligned to a "local" coordinate system
955    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
956    o Implement instantaneous output within pkg diagnostics:
957      setting a negative frequency in data.diagnostics produces
958     "snap-shot" output (as opposed to time-average if freq > 0)
959    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
960      NOTE: change ptracer diagnostics name: use 2 characters to work with
961            more than 9 tracers. Add also diagnostics of advect & diffus flux.
962    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
963      becomes the coordinate variable for the 'T' dimension
964    o add CF-style coordinate variables to MNC
965      - just a first cut:  numbers are meaningless on the cubesphere and
966        missing along the T axis but otherwise it works!
967    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
968    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
969    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
970      this is based directly on what the model compute, so that the content of
971      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
972    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
973    o clean up build options files for SunOS, in particular
974      - remove -traditional from xmakedepend
975      - change -xarch=v9 to -xarch=native for f77
976      - restore use of make (not gmake)
977      - add CC=gcc if using g77
978    o changes per discussion of AM, JMC, & EH3 today:
979      - move redundant "grid" variables out of "state" -- in preparation of
980        creating proper CF-style coordinate variables and in recognition
981        that any/all grid variables can be easily copied (eg. w/NCO) from
982        the grid files into any of the other NetCDF files
983      - *always* output grid variables with MDSIO (this will eventually be
984        changed)
985      - output MNC grid file if useMNC is true
986    o every instance of _END_MASTER() has been found and replaced with
987      _END_MASTER( myThid ) in order to satisfy certain picky Sun
988      preprocessors
989    o re-arrange diagnostics pkg initialisation:
990     - allow each package to extend the available diagnostics list
991     - add some checking and fix small problems (multi-threaded, ...)
992     - new S/R diagnostics_fill (replace fill_diagnostics):
993       look through the short list of active diag. (instead of the long list)
994       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
995    
996    checkpoint57a_post
997    o this set of changes restores TAMC compatibility
998      tested for global_ocean.90x40x15 adjoint on trough
999      (what a pain)
1000    
1001    checkpoint57a_pre
1002    o some modifs in tools/build_options for sunos
1003    o call ctrl_pack for ctrl at end for optimcycle=0
1004    
1005    checkpoint57
1006    o add horizontal bi-harmonic viscosity for vertical velocity
1007      - new parameter viscA4W (defaults to viscA4)
1008      - affects only non-hydrostatic code
1009      - to be done: no-slip lateral boundary conditions
1010    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1011    o implement Implicit Vertical advection for pTracers
1012    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1013      (implemented also for implicit vertical diffusion & advection)
1014    o OBCS: extend application of tracer open boundary conditions
1015      to a strip beyond the boundary of width Olx/Oly
1016    o add call monitor to TAF set of required calls (flow directives)
1017      and include in natl_box_adjoint
1018    o untangle a few ifdefs related to cost, ctrl, autodiff
1019      untangel a few ALLOW_ECCO_OPTIMIZATION
1020    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1021      (theta2, salt2 in ecco_cost_weights)
1022    
1023    checkpoint56c_post
1024    o OBCS as control variables
1025      - update ctrl_ad_diff.list, obcs_ad_diff.list
1026      - remove balance of obcs controls from default
1027      - fix index bug nobcs in ctrl_init
1028      - fix dummy fields filen in ctrl_pack
1029      - add dummy weights for obcs
1030    o lsopt: comment out fort.94 output
1031    o optim:
1032      - remove unnecessary header files
1033      - adjusted namelists
1034      - add xerbla.F to Makefile
1035    o exf:
1036      - multiple modifications of exf_check_range
1037      - unit change in exf_init_runoff from [m/year] to [m/s]
1038    o mdsio:
1039      - i/o-vector change debugLevel from debLevA to debLevB
1040    
1041    checkpoint56b_post
1042    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1043      is called from DO_THE_MODEL_IO
1044      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1045      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1046      - clean up PTRACERS_WRITE_TIMEAVE a little
1047    o add another verification experiment that tests both the cfc-pkg and
1048      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1049      reactive tendencies treated inline with regular timestepping
1050    o testreport previously did a lousy job of comparing small numbers, so
1051      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1052      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1053      testreport.
1054    o ptracers_monitor: bug fix for MPI
1055    
1056    checkpoint56a_post
1057    o GCHEM: finish reorganizating the package
1058      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1059        (introduces another 3D-array for each passive tracer, but only if
1060        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1061        gchemTendency is not needed because the timestep is done separately)
1062      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1063      - GCHEM is now---more or less cleanly---separate from PTRACERS
1064      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1065        so clear to me how that should be done in a general way.
1066    o CFC: improve formatting of output in CFC_ATMOS
1067    o PTRACERS:
1068      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1069        that ALL experiments with ptracers enable can be checked. This makes
1070        GCHEM_MONITOR obsolete.
1071      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1072        monitorFreq
1073      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1074    o add PTRACERS (PTR0[1-5]) to testreport output
1075    o exf_check_range:
1076      * default changed to .TRUE.
1077      * will check values for niter0 if debLevA, every timestep if debLevB
1078      * STOP in exf_check_range if 'out of range'
1079      * range chosen generous to allow for potential extema
1080      TBD: a version with stricter range
1081           permitted range would be runtime parameters
1082    o GMredi:
1083      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1084      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
1085      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
1086    o GCHEM:
1087      - move call to GCHEM_FORCING_SEP, so that it is now called before
1088        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
1089      - introduced a useGCHEM runtime flag and applied it everywhere.
1090      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1091        this flag is now only visible within GCHEM-pkg routines.
1092      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1093        be replaced by a 3D array that is computed before thermodynamics; for
1094        this, the tracer ID iTracer had to be included into the parameter list
1095        of ptracers_forcing
1096      - set up forward_step to call gchem_forcing, that will replace
1097        gchem_forcing_int in ptracers_forcing
1098      - cleaning up
1099    o small cleaning of exch2: remove files that are also in eesupp/src
1100    
1101    checkpoint56
1102    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
1103    o mnc: cleanup "full" files--fixes out-of-memory problem
1104    o ECCO-GODAE
1105      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
1106      * fully merged and updated from SIO code
1107        windstress sign change affects
1108        - exf_inscal_[u/v]stress
1109        - sign of xx_tau[u/v] adjustments
1110        - signs in cost_scat
1111      * ctrl_get_gen: avoid update of tau[u/v] for first few days
1112      * natl_box_adjoint updated and compressed
1113      * 2-level checkpoint switch added
1114        (tested in EXP. 1 of natl_box_adjoint)
1115      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
1116    o SVD
1117      * first complete, non-hacked version for SVD calculations
1118      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
1119        performed via direct access files admtlm_vector.it????
1120        (via ctrl_[un]pack)
1121      * optimcycle is used for ARPACK iteration counter
1122        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
1123      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
1124        and add linear transforms where necessary
1125      * controls are initial/final SST, SSS (can be extended; need to check
1126        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
1127    o mdsio: filename info to both stderr, stdout
1128    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
1129      from sign change
1130    
1131    checkpoint55j_post
1132    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
1133      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1134    o add consistent build directories and .cvsignore files to verification
1135    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
1136    o make all subroutines 30 or less characters in length for certain older
1137      compilers to work (a thorough search only turns up two routines in
1138      pkg/ptracers)
1139    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
1140      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1141    
1142    checkpoint55i_post
1143    o change arrays for total vertical diffusivity (2.D if explicit,
1144      3.D if implicit) ; each ptracer uses its own background value.
1145    o added mnc/NetCDF output capability to ocn_compon_interf
1146      - added bits to verification/cpl_aim+ocn so that it can run on
1147        ITRDA and other clusters without the mpirun "-wd" option
1148    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
1149      configuration
1150    o give MNC the ability to create additional files rather than
1151      exceeding a specified file size limit "MNC_MAX_FILESIZE"
1152      - the default is just less than 2GB which is a practical limit
1153        on many systems
1154    o Compute the non-local term using either KPP vertical diffusivity (=default)
1155       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
1156    
1157    checkpoint55h_post
1158    o add verification test "vermix"
1159    o remove all the *_ioinc flags and replace with the single global
1160      outputTypesInclusive flag
1161    o allow to set a vertical profile of vertical diffusivity for T & S
1162    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
1163    o useMNC moved from data.mnc to data.pkg
1164    
1165    checkpoint55g_post
1166    o Renaming carbon AD experiments to comply with testreport conventions
1167    o Updating adjoint of Held-Suarez hs94.1x64x5
1168    o Fixing directives for non-ECCO forward_step, after ECCO directives
1169      have been fixed to avoid recomp. of do_oceanic_phys
1170      Works well for global_ocean.90x40x15,
1171      but recomp. issue remains for carbon
1172    o Updating adjoint output for natl_box_adjoint after
1173      pkg/ecco has been modified (see taga c55d_post)
1174    
1175    checkpoint55f_post
1176    o rename to timeave_init_fixed
1177    
1178    checkpoint55e_post
1179    o some delicate re-shuffle of store directives to avoid one
1180      extra call of do_oceanic_physics
1181      affects ecco_the_main_loop.F, do_oceanic_physics.F
1182      checkpoint_lev1_directives.h
1183    o NB: this may break global_ocean adjoint temporarily,
1184      but it is clear how to fix it. Will do later, need this now.
1185    
1186    checkpoint55d_post
1187    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1188    o ecco_cost_weights is modified to 1x1 runs
1189    o modifs to allow observations to be read in as
1190      single file or yearly files
1191    o enable to read exf forcing fields as either
1192      single file or yearly files (flag useExfYearlyFields)
1193    checkpoint55d_pre
1194    
1195    o switch between 2-level and 3-level checkpointing
1196    o add ability of MNC to write local and "partial" (eg. 2D slices where
1197      the full 3D field is never actually stored) arrays to NetCDF files
1198      with the correct (that is, the complete multi-dimensional) set of
1199      array indicies
1200      - used in mom_vecinv() to write the diagFreq output
1201      - tested (demonstrated) in verification/aim.5l_cs
1202    o further mnc-ification
1203      - add verification/lab_sea to the list with mnc setups
1204      - fix undefined mnc v-names in cd_code
1205      - add kpp to mnc output (both snapshot and timeave)
1206    o non-hydrostatic code
1207      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1208        in calc_gw.F
1209      - defaults to viscAh
1210      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1211        friction or Leith) in non-hydrostatic mode, as long as there is
1212        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1213    o pkg/cost
1214      extend simple cost functions to treat time mean quantities
1215      (T,U,V) via cost_accumulate_state from cost_tile
1216    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1217        be 2 times larger than the minimum size the advection scheme requires.
1218        now get a perfect conservation of salt in advect_cs test-exp (updated)
1219    o GGL90 (Gaspar's TKE mixed layer)
1220      - add horizontal diffusion of TKE, requires exchanges in
1221        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1222        default. In OPA there is no horizontal diffusion of TKE but the
1223        mixing coefficients are computed from a horizontal average of TKE of
1224        6 points or so. I think that diffusion has a little more physical
1225        justification.
1226      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1227        was in vain)
1228      - mask tke-variable in ggl90_init
1229    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1230    o fix biharmonic diffusion on CS-grid.
1231    o more obcs stuff
1232      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1233        for reading boundary values. This routine is called from
1234        obcs_prescribe_read
1235      - updated obcs_check
1236      - changed sponge layer relaxation parameter units for days to seconds
1237      - turned off sponge layer by default
1238      - changed argument list of OBCS_CALC to myTime+deltaTclock
1239      - fixed about 35 bugs in obcs_external_fields_load
1240    
1241    checkpoint55c_post
1242    o obcs stuff
1243      - new runtime flags useOBCSprescribe, useOBCSbalance
1244      - re-arranged obcs_calc
1245      - moved exf_getobcs to obcs_prescibe_read
1246        obcs_prescibe_read is called after ORLANSKI stuff
1247        and independent of it (executable can contain all).
1248      - updated obcs_check
1249      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1250        These may be necessary only if tangential velocities are
1251        prescribed at OB, not sure, needs testing.
1252    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1253      which simplifies the calls and passes the ifc check-bounds test
1254    
1255    checkpoint55b_post
1256    o add a 2D scalar, Z location, exchange_2 routine.
1257    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1258      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1259      affects advect_cs results (for the wrong reason): update output.txt
1260    o use a more standard discretization for biharmonic viscosity ;
1261     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1262      affects results of dome set-up: update output.txt
1263    o fix gad_advection.F (CubedSphere part), back to version 1.23
1264    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1265    
1266    checkpoint55a_post
1267    o merged code to
1268      * prescribe/read time-dependent open boundaries
1269        (works in conjunction with exf, cal)
1270      * sponge layer code for open boundaries
1271      * each boundary N/S/E/W now has its own CPP option
1272        (healthy for the adjoint)
1273    
1274    checkpoint55
1275    o up-to-date adjoint of previous breaks
1276      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1277      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1278      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1279      - carbon: * remove tr1-related adjoint verification
1280                * add ptracer as control variable
1281    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1282      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1283    
1284    checkpoint54f_post
1285    o in verification/carbin/ remove experiment related to
1286      ALLOW_PASSIVE_TRACER (array tr1 etc)
1287      code_ad/ input_ad/ results_ad
1288    
1289    o add two new packages
1290      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1291        + subject to optimization (memory)
1292      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1293        + subject to reordering (many GOTOs in the original code)
1294        + so far opps is called for every (i,j) point, and then operates in
1295          the vertical; one may want to reorder the scheme in order operate in
1296          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1297          fields)
1298    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1299      - all verification tests compile and run with linux_ia32_g77
1300      - defaults are compatible with current input files--nothing
1301        should change if you were not previously using MNC
1302      - MNC output has been added in numerous places (eg. timeave)
1303        but there are still a few writes not yet do-able with MNC
1304        (this is in progress)
1305      - flags now allow for either/or/both use of MDSIO and MNC and
1306        documentation will soon follow
1307      - numerous small formatting cleanups for ProTeX
1308    o add version info (via BUILD_INFO.h) to MNC and stdout
1309    
1310    checkpoint54e_post
1311    o add two new packages
1312      - pp81 (Packanowski and Philander, 1981), Richardson number and
1313        stratification dependent mixing
1314      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1315      - these scheme operate in a similar manner as KPP (without ghat, of
1316        course), however there is only one diffusivity that is used for both
1317        temperature and salinity (and passive tracers)ç
1318    o add offline package
1319    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1320      provided by Stephanie Dutkiewicz
1321    o genmake2: add ability to search for C compilers and cleanup test output
1322      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1323    
1324    checkpoint54d_post
1325    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1326    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1327      leading to additional shift by 5 days each year of integration
1328       (i.e. leading to considerable offset over the years)
1329    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1330    o start with no AB and no initial filtering (staggerTimeStep):
1331      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1332    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1333      (external loading & cpl import/export stay in forward_step.F)
1334    o update coupling interface to work with new staggerTimeStep
1335    o change MDSIO ptracers_pickup.
1336    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1337    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1338    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1339    
1340    checkpoint54c_post
1341    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1342      this affects (truncation error) output.txt of test-exp:
1343       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1344    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1345    o change Qnet to always be the net heat flux, (+upward).
1346      affects (truncation error) output of natl_box exp.: updated
1347    o define the max number of passive tracers in PTRACERS_SIZE.h
1348    o start to test mnc routinely in exp0
1349    o add sea-ice loading (sIceLoad) as a new forcing field.
1350    
1351    checkpoint54b_post
1352    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1353       impressive on Altix and Opteron systems)
1354    o diagnostics can now write NetCDF files through the mnc package
1355    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1356    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1357    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1358      affects (truncation error) output of lab_sea & natl_box exp.: updated
1359    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1360    
1361    checkpoint54a_post
1362    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1363    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1364    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1365    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1366      + internal_wave (shift in writing cg2d_ini_res)
1367    checkpoint54a_pre
1368    
1369    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1370      - modified verification/lab_sea and natl_box_adjoint accordingly
1371    
1372    checkpoint54
1373    checkpoint53g_post
1374    o prepare splitting of thermodynamics: store convect.counter in common block
1375    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1376      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1377    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1378    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1379    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1380    o restore adjointability
1381    
1382    checkpoint53f_post
1383    o modifications that affect AIM experiment results (update output.txt):
1384      - no advection of S at top interface Nr (pkg/generic_advdiff)
1385      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1386    o AIM pkg:
1387      - include stability function into surf.Flux derivative relative to Tsurf
1388      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1389    
1390    checkpoint53e_post
1391    o merged cylindrical coord configuration
1392    o added rotating_tank experiment
1393    checkpoint53e_pre
1394    
1395    checkpoint53d_post
1396    o faulks upgraded: re-generate output.txt that have changed:
1397       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1398    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1399    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1400    o added Sadourny discretization of Coriolis
1401      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1402      - re-enabled use of omega3 (useAbsVorticity)
1403    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1404      vector-invariant equations
1405      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1406    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1407      hopefully without new bugs
1408      - still to do: biharmonic friction for non-hydrostatic w
1409    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1410    o regenerated output for global_ocean_ebm (using -ieee)
1411    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1412      of mom_common/
1413      - simple re-arrangement of instructions within computing loop
1414    checkpoint53d_pre
1415    
1416    checkpoint53c_post
1417    o new version of coupler for AIM+thSIce and Ocean models
1418     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1419     - land: change Evaporation of snow
1420     - aim with thSIce: fix bug in snow-precip.
1421    o changes to calc_gw.F
1422     - bug fix for w^2 term near the bottom boundary
1423     - (hopefully) improve the lateral slip boundary condtions for use with
1424        partial/looped cells
1425      - because the bug fix changes two verification experiments anyway (exp5
1426        and plume on slope), change the lateral boundary condition from half slip
1427        to the value of no_slip_sides
1428    o ebm package wasnt quite up to the parallel task. Fixed that.
1429    o Adjoint of EBM package + verification
1430      * TLM OK
1431      * ADM not sufficient accuracy yet (needs further testing)
1432    
1433    checkpoint53b_post
1434    o Commiting new energy balance model to repository
1435      * package is pkg/ebm
1436      * verif. is verification/global_ocean_ebm
1437      * references are in ebm_driver.F
1438    C      * X. Wang, P. Stone and J. Marotzke, 1999:

1449    C        J. Climate 7(12), 1870-1882
1450    o Will need long integration testing.
1451    checkpoint53b_pre
1452    
1453    o created pkg/mom_common in preparation for variable viscosity code
1454    o renamed and split ini_mnc_io
1455    o pkg/land: only liquid water can diffuse or run-off
1456    o AIM using land: soil wetness availability account for snow
1457    o added printMapIncludesZeros to EEPARMS namelist
1458    
1459    checkpoint53a_post
1460    o restore TAMC compatiility for exf_constants.h
1461      (no usage of _d in .h)
1462    o Additional storing in KPP in an attempt to fix
1463      TAMC problem with adjoint of KPP code.
1464      (no success...)
1465      Identical code works fine with TAF.
1466    o Fixed verification/natl_box_adjoint experiments.
1467      Initial conditions for Experiments 4 and 5 are now
1468      set to "SEAICE_initialHEFF=0", which is more reasonable,
1469      and hence gives results closer to that of Experiment 2.
1470      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1471    
1472    checkpoint53
1473    o stable checkpoint with up to date adjoint
1474      TLM tests only run for 1st grdchk at the moment. Its unclear if
1475      this is a code problem or a problem with resetting code for g_
1476      variables that is being autogenerated wrong.
1477      Otherwise:
1478       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1479       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1480         are both still in chaos following their security messes.
1481    
1482    checkpoint52n_post
1483    o various build (mostly genmake2) changes including:
1484      - ability to build/run more easily within Cygwin and MacOS X
1485      - more complicated Makefiles with a stronger dependence on Gnu Make
1486    o pkg/seaice modifications
1487      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1488        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1489        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1490      - changed proxy for geostrophic velocity and updated
1491        verification/lab_sea/results/* accordingly
1492      - removed ADI dynamic solver from pkg/seaice
1493      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1494        they caused a segmentation fault under certain circumstances
1495      - removed unused field WATR
1496    o bug fix in exf-package:
1497      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1498         now reflect that.
1499    o small fixes in the cal-package:
1500      - set reference date to first of January for the 'model'-calendar
1501      - failing of cal_CheckDate in cal_FullDate now actually results in a
1502        warning
1503    o small modifications in exf-package to increase flexibility:
1504      - change climtempfreeze from a constant to a runtime parameter that
1505        is specified in data.exf_clim (default = -1.9)
1506      - introduce runtime parameter windstressmax (default = 2.0) that is
1507        specified in data.exf
1508    o fix in pkg/thsice:
1509      - update Evap (Tsf changes) to be consistent with Latent heat flux
1510      - maintain snow precipitation unchanged (even if Tsf >=0).
1511     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1512    
1513    checkpoint52m_post
1514    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1515      this does not change any of the results, because myIter=0 in swfrac always
1516      lead to jwtype=2 (the default anyway), but the call makes little sense
1517      as a default
1518    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1519    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1520      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1521    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1522    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1523    o extending useSingleCpuIO option to work with new exch2 I/O format
1524      - old-style, missing-tile I/O is still accessible by defining CPP
1525        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1526    o monitor package can write to NetCDF files and/or STDOUT
1527    o fix re-definition bug in MNC_GRID_INIT_ALL()
1528    o doc/api_reference added
1529      - a framework for building an API Reference Manual using all
1530        the "protex" comments embedded in the code
1531      - see pkg/generic_advdiff, pkg/mnc for examples
1532    o MNC:
1533      - make myThid the last argument for all subroutines
1534      - new default for the grid files: NO halos
1535      - add useMNC and other run-time flags
1536      - separate per-file-group handling of the unlimited dimension
1537      - early initialization of MNC w/ flags read at the eeboot stage
1538        and lookup tables set in initialize_fixed
1539      - write all MNC output to a freshly-created directory
1540    o thermodynamics sea-ice (thsice) is now tested with testreport.
1541    o test exp. advect_cs: use the standard cs32 grid ; update output.
1542    o Added functionality to grdchk:
1543      pick global i,j,k position (or nearest wet) where to perform check.
1544    
1545    checkpoint52l_post
1546    o new land formulation:
1547      a) use ground enthalpy as prognostic variable to ensure exact
1548         energy conservation.
1549      b) account for water temperature and for latent heat of freezing
1550         in all processes (rain, run-off, ground storage)
1551      c) compute surface and ground temperature implicitly.
1552    o aim_v23 modification for new land model:
1553      a) Treat separately land / ocean / sea-ice surface fluxes
1554         to allow implicit computation of land & sea-ice surface temp.
1555      b) add snow precipitation.
1556    checkpoint52l_pre
1557    
1558    o fix problem (when 1 tile is empty) in min/max monitor.
1559    o fix bug in timeAve (u,vZetatave in common block)
1560    o no restoring terms under ice for pkg/seaice
1561    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1562    o bug fix for pkg/seaice pickups
1563    o change MNC call locations and add coordinate attributes
1564    o mask vorticity at the corner ; affects global_ocean.cs output
1565    o fix ini_curvilinear_grid ; test CS experiments with mpi
1566    o aim.5l_cs: modify sea-ice fraction input file ; update output
1567    o exf: Adding simple range check routine for exf fields after read
1568    
1569    checkpoint52k_post
1570    o removed top-level directory "diags"
1571      - we migrated these functions to pkg/timeave a long time ago
1572    o fixed bug introduced in pkg/monitor
1573    o accuracy ctrlprec = 32 insuffient for gradient checks using
1574      averaged fields (I/O via cost_averages)
1575      -> use ctrl.h in active_file*.F to control I/O precision.
1576    o paramter list of CALL ADTHE_MAIN_LOOP
1577    o added initial do_the_model_io to ecco
1578    o set all ...Freq to zero after cost_final
1579      taveFreq, dumpFreq, pChkptFreq
1580    o MAIN and ECCO differentiability restored
1581    
1582    checkpoint52j_post
1583    o fix nchklev in tamc.h for global_ocean...
1584    o Bringing flow and store directives up-to-date
1585    o Really weird thing!
1586      call do_the_model_io from the_main_loop with parameters
1587      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1588      TAF places a faulty re-call of initialise_varia
1589      after cost_final call which should not be there!
1590    checkpoint52j_pre
1591    
1592    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1593      error messages
1594    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1595    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1596      debug output
1597    o modfied mdsio_writefield.F to handle non-global files under exch2
1598    o update AIM Cubed-Sphere exp (aim.5l_cs):
1599      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1600    o update AIM Equatorial Channel exp:
1601      use standard aim_v23 pkg and change the SST fields to be more realistic.
1602    o globalFile now works with exch2
1603    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1604      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1605    o limit timeave output for hi-res integrations
1606    
1607    checkpoint52i_post
1608    o removed CPP_EEOPTIONS.h from verification/*/code
1609    o updated the tiling for global_ocean_pressure
1610    checkpoint52i_pre
1611    
1612    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1613      the old pkg/aim).
1614    
1615    checkpoint52h_pre
1616    o shortened offending lines in exch2_send_rx?.template
1617    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1618    o genmake2: add build & execute test for NetCDF code
1619    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1620      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1621    o added useSingleCPUIO flag to monitor.F and mon_out.F
1622    o added temporary hack for sea-ice dynamics on the cube:
1623      metric terms are ignored and it is assumed that
1624      there is no sea-ice on cube faces 1, 2, 4, and 5.
1625    
1626    checkpoint52f_post
1627    o added exch2 cube routines to pkg/exch2
1628    o modified hs94.cs-32x32x5 to use it
1629    o added new grid files to hs94.cs-32x32x5
1630    checkpoint52f_pre
1631    
1632    checkpoint52e_post
1633    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1634      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1635    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1636      to work with implicit vertical advection and AB ;
1637    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1638    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1639     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1640    checkpoint52e_pre
1641    
1642    o fix bug in impldiff when Nr=1 or Nr=2.
1643    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1644    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1645    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1646      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1647    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1648    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1649    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1650    
1651    checkpoint52d_post
1652    o re-tiled many expts to allow comparison in multi-processor mode
1653      - updated output accordingly
1654      - changed hs94.128x64x5 to use intial T from file rather than use the
1655        random number generator
1656    o add infrastructure in model routines for fizhi and gridalt packages
1657    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1658    o changes to permit hi-res, cubed-sphere, configuration
1659      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1660      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1661      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1662        of surface winds for the cube
1663      (A verification experiment, based on global_ocean.cs32x15, but with
1664       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1665       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1666       complete with example surface forcing files and matlab scripts to look
1667       at the output and compare it with that of global_ocean.cs32x15.)
1668    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1669       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1670       to conform to the common rule.
1671    o check-in the first version of the coupler + interfaces for multi-components
1672       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1673       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1674       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1675       - ocean and atmos. share the same horizontal grid (no interpolation).
1676       - exchanges between component and coupler is done in forward_step
1677    o new verification experiment, cpl_aim+ocn:
1678       coupled ocean - AIM atmosphere on cs32 grid.
1679    
1680    checkpoint52d_pre
1681    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1682    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1683    
1684    checkpoint52c_post
1685    o Fixing OPTIONS files for use of exf:
1686      - ALLOW_ECCO not needed
1687      - ECCO_CPPOPTIONS.h should not be included from
1688        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1689        as has been the case in the past
1690      - All cal/exf related options are currently set in
1691        single header file. Should remain so until we
1692        agree on a consistent new policy.
1693    o Removed all CPP options for cal package.
1694      cal has no more CPP options.
1695    o modified STOREs in GAD_ADVECTION
1696    o corrected key comp. for passkey
1697    
1698    checkpoint52b_post
1699    o new version: "thsice" of thermodynamic sea-ice pkg:
1700     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1701     - modify fluxes but do not change theta directly;
1702     - light cleaning of bulk_force pkg (still needed with thsice).
1703     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1704       + output_thsice.txt to test thsice & bulk_force pkgs.
1705    o put back grid & coriolis monitor output.
1706    checkpoint52b_pre
1707    
1708    o call "do_the_model_io" at the beginning (=> dump initial state)
1709    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1710    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1711      (need info on NUMBER_OF_PTRACERS)
1712    o missing PTRACERS headers in some routines
1713    o default tamc.h in pkg/autodiff supposed to crash
1714      to ensure proper customization
1715    
1716    checkpoint52a_post
1717    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1718      - moved surfaceTendencyTice from pkg/seaice to main code
1719      - subroutine FREEZE_SURFACE now limits only surface temperature
1720        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1721        => new output.txt for global_ocean.cs32x15 & global_with_exf
1722      - keep the old version of FREEZE for backward compatibility;
1723        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1724      - corresponding modifs for TAF directives
1725    o added surface flux output variables to TIMEAVE_STATVARS
1726    o time-averaged output for pkg/ptracers
1727    o fix problem with ECCO-related divided adjoint
1728      snapshot file was missing some ad-variables,
1729      but no warning issued by TAF
1730    
1731    checkpoint52a_pre
1732    o some bug fixes for #undef REAL4_IS_SLOW
1733    
1734    checkpoint52 = ecco_c52_e35
1735    o after testing adjoints of checkpoint51u_post
1736    
1737    checkpoint51u_post
1738    o this is the post-merge tag of the ecco-branch
1739      (needs another clean checkout and re-testing)
1740    o various natl_box_adjoint configs and results
1741      but no input fields
1742    o obcs adjoint not yet merged!
1743    o adding ECCO global 1x1 and 2x2 degree configs
1744    o updated/extended some store directives for seaice
1745    o pkg/ecco now containes ecco-specific part of cost function
1746    o top level routines the_main_loop, forward_step
1747      supersede those in model/src/
1748      previous input data.cost now in data.ecco
1749      (new namelist ecco_cost_nml)
1750    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1751    
1752    checkpoint51t_post
1753    o this is the pre-merge tag of the ecco-branch
1754    
1755    checkpoint51s_post
1756    o cleanup: removed various obsolete #define-s
1757    o pkg/grdchk
1758      - renamed 'ph-grd 3' to 'grad-res'
1759      - merged from ecco-branch
1760        (remaining bug fixes for obcs gradient checks)
1761      - additional high-precision output for testreport
1762        (grep for 'precision_grdchk_result')
1763    
1764    checkpoint51r_post
1765    o cleaned up or removed CPP_OPTIONS.h files
1766    o updated results for some of the tests to reflect the new
1767      optfiles (-ieee: -O0 instead of -O3)
1768    
1769    checkpoint51q_post
1770    o cd_code:
1771      - moved cd_scheme.F -> cd_code_scheme.F
1772      - separate read_checkpoint from cd_code_ini_vars.F
1773      - separated cd_code part from write_checkpoint
1774      - updated AD_SOURCE, generated .flow
1775      - added CD_CODE_VARS.h to the_main_loop
1776      - Moving cd_code specific store dir.s to pkg/cd_code
1777    o ctrl package totally restructured
1778      - pack/unpack now optional and decoupled from
1779        xx_/adxx_ I/O
1780      - ctrl_pack/unpack cleaned
1781        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1782      - confined inclusion of AD_CONFIG.h to where necessary.
1783    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1784    
1785    checkpoint51p_post
1786    o create initial cd_code package
1787      - WARNING: the initialization of fields within packages
1788        is broken because INI_FIELDS (where READ_CHECKPOINT is
1789        called) is called *before* PACKAGES_INIT_VARIABLES.
1790        This seems to be backwards since
1791        1) its important to initially zero the entire field including
1792           the "halo" region
1793        2) zeroing needs to be done *before* reading pickup info
1794           and the pickup call might or might not happen in any
1795           particular run
1796      - this needs an overhaul for R2
1797    o cleanup verification/*/code/GMREDI_OPTIONS.h
1798    o cleanup testreport
1799    
1800    checkpoint51o_post
1801    o bringing AD-related verif's up to date with genmake2
1802      - carbon/
1803      - global_ocean.90x40x15/
1804      - hs.94.1x64x5/
1805      - (front_relax/ )
1806    o (more) consistent directory structure for AD-related verif.'s
1807    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
1808    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1809    o bug fix in find_alpha.F for MDJWF:
1810      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1811        change rho -> rho-rhoConst
1812      - replace call find_rho to find_rhonum
1813    o initialisation of rFlx extended to full array (required by TAF)
1814      and shifted to thermodynamics
1815    o removed PTRACERS.h in ptracers routine
1816    o added surfacetendencyPtr to S/R parameter list pracers_forcing
1817    o Correcting initialisations for fVerU, fVerV.
1818    o helping TAF to recognize dependency on kUp for
1819      fVerU, fVerV
1820    o Replacing delZ by delR in pkg/ctrl/
1821    checkpoint51o_pre
1822    
1823    o undid all of cp51 pending some cleanups and discussion
1824    o added the [#include "AD_CONFIG.h"] statement to all files that need
1825       it for adjoint/tl #defines
1826     o re-worked the build logic in genmake2 to support AD_CONFIG.h
1827     o removed tools/genmake since it no longer works
1828    
1829    checkpoint51n_post
1830    o modifications to make FREEZE flux visible to pkg/kpp
1831      - moved surfaceTendencyTice from pkg/seaice to main code
