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    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

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
