5      ==============================      ==============================
6    
7    checkpoint58x_post
8    o IO option for global-file compact format:
9      - add options when generating topology (utils/exch2/matlab-topology-generator)
10      - add I/O capability (pkg/mdsio).
11      - adapt utils/matlab/rdmds.m to read this format.
12      for now long-line format not yet supported by pkg/mdsio (& exch2).
13    o shelfice: add a few diagnostics
14    
15    checkpoint58w_post
16    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
17      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
18      (and replace horiVertRatio in NH code).
19      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
20                         and tutorial_plume_on_slope (sensitive to truncation)
21    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
22      directly to drive seaice model (C-grid only)
23    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
24     - reintroduce computation of wind from stress,
25     - compute tau (in exf_bulkformulae.F) from windstress averaged to
26       mass points to avoid tau = 0
27     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
28    o rdmnc.m: make it work with "global" files created with gluemnc
29    o rdmnc.m : some improvements in dealing with singleton dimension
30      (tested on all testreport mnc output files).
31    o genmake2: disable pkg/profiles if netcdf test fails.
32    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
33    o move call to cal_readparms up to make calendar parameters/variable available
34      to all packages
35    
36    checkpoint58v_post
37    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
38      useDynP_inEos_Zc tested.
39    o pkg/exf: changes to properly interpolate/mask/scale initial fields
40    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
41      and portions thereof.  See read_cs.txt for description and examples.
42    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
43      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
44      following the great-circle arc between those 2 points.
45    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
46      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
47    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
48     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
49     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
50     - still needs work (not working with some options ; efficiency to improve)
51       and serious testing.
52     - use this scheme for temperature & salinity in 2 advection test exp.:
53       advect_xy & advect_xz, respectively.
54    
55    checkpoint58u_post
56    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
57    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
58    o testreport: add option "-skipdir" to skip some test.
59    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
60      momentum calculation.
61    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
62    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
63      remove checkpoint.F and the_correction_step.F (no longer used);
64      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
65    o add option (linFSConserveTr) to correct for tracer source/sink due to
66      Linear Free surface
67    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
68    o pkg/thsice: fix reading mnc-pickups
69    
70    checkpoint58t_post
71    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
72    o pkg/mdsio:
73     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
74       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
75       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
76     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
77     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
78       either MDS_READ_FIELD or MDS_WRITE_FIELD )
79     - new S/R (to replace MDSWRITEMETA), which allows to write more
80       informations (variable names, time ...) to meta files.
81     - modify rdmds.m to give back the meta file content.
82    o pkg/diagnostics: change vertical interpolation to be safer, and more
83       flexible (define p-levels to interpolate to in data.diagnostics);
84      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
85       diagnostic pointer.
86    o pkg/seaice: more cleaning up of seaice_growth, added many comments
87    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
88    o fix multi-category seaice:
89     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
90       SEAICE_MULTICATEGORY
91     - fix short wave heat flux
92    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
93       and allow to use EVP solver. Change forward lab_sea: test both EVP
94       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
95    o Initial check-in of lab_sea adjoint
96      (very similar to natl_box_adjoint/code_seaice)
97      * used C-grid and EVP solver
98      * used KPP, GM/Redi
99      * uses inAdExact=.TRUE.
100      * gradient checks fail for both ADM and TLM
101        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
102        f.d. gradients actually seem more problematic than ADM, TLM gradients;
103        issue is related to forward mismatch between g77 an ifort
104    o pkg/seaice: overhaul of thermodynamics
105     - growth.F and groatb.F are replaced by new routine seaice_growth.F
106     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
107     - move a few global fields out of SEAICE.h into seaice_growth.F and
108       make them 2D (FICE/QNETO/ ...)
109     - remove FO (it is the same as QNETO)
110     - introduce a few local fields to avoid modifying external fields such
111       as atemp, etc.
112    
113    checkpoint58s_post
114    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
115      changed exf_set_gen.F so that
116        genperiod=0 means input file is one time-constant field and
117        genperiod=-12 means input file contains 12 monthly means
118    o CG2D: use pre-computed solver main-diagonal (stored in common block);
119      this affects truncation error ; generate new output file for exp. which
120      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
121        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
122        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
123        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
124        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
125        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
126    o start implementation of deep-atmosphere and anelastic formulation
127    o verification: remove 2nd copy of input files and use script "prepare_run"
128      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
129    o mom_common/vecinv/fluxform: fix a few initialisation isssues
130    o profiles: fix for multithreaded case
131    
132    o diagnostics: rename few diags:
133      s/'PRESSURE'/'RCENTER '/g
134      s/'TICE    '/'oceFreez'/g
135      s/'TAUX    '/'oceTAUX '/g
136      s/'TAUY    '/'oceTAUY '/g
137      s/'SWFLUX  '/'oceQsw  '/g
138      s/DIFx/DFxE/g
139      s/DIFy/DFyE/g
140      and add few ocean-forcing diagnostics:
141      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
142    o modifications to pkg/seaice/growth.F and budget.F, which change results of
143      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
144      as actual snow thickness.  It now refers everywhere to effective snow
145      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
146    
147    checkpoint58r_post
148    o modifications to pkg/seaice/growth.F, which change results of
149      lab_sea experiment: fixes pertain to melting snow over open water, to
150      masking EVAP under sea ice, and to using the correct AREA variable for
151      computations of EVAP, PRECIP, HSNOW, and GHEFF
152    o add ability to read bathy, salt, and theta using MNC (off by def)
153    o add flooding algorithm and advection of HSNOW for pkg/seaice;
154      both are turned off by default and do no change any results
155    o seaice advection with pkg/thsice: a step toward the use of non-linear
156      advection scheme, but #ifdef or commented out for now (requires more EXCH).
157    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
158      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
159      in natl_box (affects results @ truncation level: update output.txt)
160    o multi-threading and IO:
161      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
162      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
163        (needed to work with SingleCpuIO): tested in all verif. exp.
164    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
165      affects the results (but none of the verification test uses this scheme).
166    o Adding some pkg/diagnostics capability to pkg/seaice
167      (will certainly be subject to changes)
168    o ctrl: adding new control variables:
169      lwflux, lwdown, evap, snowprecip, apressure, runoff
170    
171    checkpoint58q_post
172    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
173      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
174      high_res_cube configuration by 4% on Columbia.
175    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
176      add (in global_with_exf/code) a version of EXF_INTERP_READ without
177      dynamical allocation (seems to work in multi-threaded).
178    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
179      single CPU io) so that TAF does not have to see EESUPPORT.h
180    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
181    
182    checkpoint58p_post
183    o obcs: stop if obcs is used with useCDscheme = .true.
184    o shelfice:
185     - fix a sign error so that no slip at shelfice interface works
186     - remove stop for combination non-hydrostatic code and shelfice. That does
187       not mean, that the results are correct, but at least they are numerically
188       stable
189    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
190    o added adjoint exch routined for all exch*3d* routines
191      and updated flow directives
192    
193    checkpoint58o_post
194    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
195      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
196    o change controling S/R for writing pickup file (new S/R do_write_pickup)
197      and clean-up reading/writing of pickup files.
198    o fix local version of read/write pickup (NH part) in rotating_tank/code
199    o simplify EXCH interface:
200     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
201     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
202    o added the regrid package
203    o shelfice:
204     - add a simple boundary layer scheme to reduce noise
205     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
206    
207    checkpoint58n_post
208    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
209       local variable (not in common block).
210    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
211      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
212      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
213        to work with SingleCpuIO.
214    o add "_d 0" to real constant of pkg/cfc subroutines ;
215       update exp. cfc_exemple & tutorial_cfc_offline output files.
216    o multi-threading and IO:
217      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
218        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
219      - barrier before and after reading.
220      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
221      - avoid using MDS_WRITELOCAL for LAND pkg output.
222      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
223        common-block variables ; Allows multi-threading with master-thread IO.
224    o change default MAX_NO_THREADS from 32 to 4 ;
225      and stop cleanly when MAX_NO_THREADS is too small.
226    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
227    
228    checkpoint58m_post
229    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
230       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
231    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
232       keep global_ocean.90x40x15 (for AD testing) with former secondary test
233       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
234    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
235        add MITgcm_tutorials (= code + all the tutorials)
236    o ecco, option to compute cost for total ssh (mean+anom)
237    o consistent with addition of ptracer and ssh in pkg/profiles
238    o profiles: adding ptracer and ssh
239    o testreport: change multi-test output-file name
240      (from output.txt.{name} to output.{name}.txt)
241    o profiles: now ok for mutli-tiles case
242    o seaice: add 4 parameters for different advection schemes for area,
243      (effective) seaice thickness, enthalphy, and snow height. Their default
244      is the standard parameter SEAICEadvScheme
245    o calc_gw:
246     - add cosFacU in zonal viscous flux (harmonic.visc.).
247     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
248       of tutorial_plume_on_slope.
249    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
250    o calc_gw: true flux-form, account for horizontal grid spacing.
251      update rotating_tank results, but not plume_on_slope (affected at
252      truncation level, 11 digits).
253    
254    checkpoint58l_post
255    o calc_gw:
256     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
257     - remove side-drag for now (need to fix it); update plume_on_slope results.
258     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
259    o commit code to make SST/SSS weights spatially variable
260      (based on either variable in-situ or variable initial T/S weights)
261    o pkg/ecco:
262      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
263        now based on horizontally varying weights wthetaLev, wsaltLev
264      * cost_averagesflags now returns year indices in addition to day, month
265      * sflux balance is performed on annual basis
266        (sflxumm, sfluxmm2, bal_sfluxmm)
267      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
268        including separate counting and multipliers
269    o pkg/rbcs
270      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
271    
272    checkpoint58k_post
273    o testreport:
274     - always build in dir. "build" (if not there, mkdir build instead of building
275       & running in input)
276     - run in dir run (if it exists), in build otherwise.
277     - call prepare_run (if input/prepare_run exists)
278     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
279    o pkg/exf modifications to interpolation and rotation routines for more
280       reasonable treatment of North Pole singularity: for tracers North Pole
281       value is set to northernmost zonal-mean value, for zonal velocity it is
282       set to zero, and for meridional velocity it is set to northernmost value.
283    o pkg/exf/exf_check_range.F
284     - add tile index to diagnostics and move stop statement to the very
285       end of the routine.
286    o pkg/diagnostics: (diagnostics_main_init.F)
287      define title of isomorphic variables according to the current config.
288    o pkg/thsice with pkg/seaice dynamics:
289    - fix domain of computation (interior only, required for exf) and do exchanges
290    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
291    o towards a standard way of dealing with multi-threading in MONITOR
292      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
293    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
294       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
295    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
296    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
297    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
298       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
299    o tracer advection:
300     - clean-up and simplify calc_common_factors.F
301     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
302       advection subroutine (but still not used within DST advection S/R)
303    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
304    
305    checkpoint58j_post
306    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
307      from file (collects calls previously in FORWARD_STEP)
308    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
309    o adjoint store dir. adjusted accordingly
310    o genmake2
311      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
312    
313    checkpoint58i_post
314    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
315      on wind stress (SEAICEstressFactor defaults to 1.)
316    o Total number of Timers is finite (<=40): comment out 2 non-essential one
317      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
318    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
319      on CS-grid: no longer loosing mass.
320    o exf & curvilinear-grid: no longer modify longitude xC & xG.
321    o pkg/ggl90: fix sloppy output and fix a bug
322    o pkg/seaice: added SEAICEuseEVPpickup parameter
323      - Set to false in order to start EVP solver with
324        non-EVP pickup files when using SEAICEuseEVP
325      - fix sign error in diffusion in seaice_calc_rhs
326    
327    checkpoint58h_post
328    * Modifications for bottom topography control
329      o replace hFacC by _hFacC at various places
330      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
331      o add non-self-adjoint cg2d_nsa
332      o update autodiff support routines
333      o re-initialise hfac after ctrl_depth_ini
334      o works for 5x5 box, doesnt work for global_ocean.90x40x15
335    * Adding verification for 5x5 box (4-layer) bottom topography control
336    
337    checkpoint58g_post
338    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
339       used for mean seasonal cycle, mean diurnal cycle); add an example
340       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
341    o pkg/ggl90:
342      - add parameter (minimum surface kinetic energy)
343      - fix bug (avoiding division by zero)
344    o couple pkg/thsice to pkg/seaice:
345      - modify advection in seaice to accomodate new scalar fields to be advected
346      - only muliDimAdection scheme work with seaice/thsice
347      - mapping of thsice-variables to seaice-variables, back and forth
348      - does not break the verification experiments, but does not give the
349        desired results either
350    o pkg/seaice
351      - make (default) second order advection a bit less confusing?
352    
353    checkpoint58f_post
354    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
355      to pkg/seaice):
356      - new routines thsice_map_exf and thsice_get_exf provide the interface
357      - add an additional formal parameter to thsice_solve4temp
358    o pkg/exf:
359      - add new fields wspeed, snowprecip (to be able to couple to thsice)
360      - correct Stefan-Boltzmann constant
361      - new parameter for longwave surface emittance
362      - separate some stuff from exf_bulkformulae into new routines  
363        exf_radiation, exf_wind
364      - add new parameters and constants: longwave emissivity for ocean, ice
365        and snow, evaporation parameters over ice
366      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
367        either wind from stress or stress from wind
368    o pkg/thSIce:
369    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
370    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
371       and THSICE_CALC_THICKN
372    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
373    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
374      to make debugging easier.
375    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
376    o pkg/bulk_force:
377      - clean-up comments and parameters ;
378      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
379    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
380      generate new output for test-experiment: aim.5l_cs.thSI
381    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
382      testreport accordingly
383    
384    checkpoint58e_post
385    o SEAICE_CGRID adjoint done
386    o R_STAR adjoint implemented.
387      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
388      * need to sort out init. of h0facc, etc.
389    o Make pkg/profile fully independent of ecco,cost, etc. stuff
390      to be able to use it in pure forward.
391    
392    checkpoint58d_post
393    o upgrade simple test-experiment to tutorial example:
394     step.1: duplicate the experiment and (step.2) will remove the old copy.
395      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
396      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
397      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
398      tutorial_global_oce_biogeo    <- copy of dic_example
399      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
400      tutorial_plume_on_slope       <- copy of plume_on_slope
401      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
402      tutorial_global_oce_optim     <- empty for now (David ?)
403      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
404     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
405    o correct a sign problem in cost_scat.F
406    o obcs and ptracers: fix boundary conditions for advections schemes
407      with larger stencil
408    o thsice adjoint: start
409    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
410      completeness
411    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
412      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
413    o ptracers adjoint:
414      * avoid extensive recomputatations
415      * fix missing re-init. of gptr (missed by TAF)
416    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
417      me to turn off the excessive output to STDOUT that this package produces
418    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
419      and add those terms in Vector-Invariant formulation.
420    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
421      if the control period (xx_hfluxperiod etc) is 0
422    o in profiles pkg, clean routines and fix details
423    o in ecco pkg, reading ssh data:
424      fix problem in case the model does not start at iter0=0
425    o fix mnc-pickup/restart for ptracers
426    o new package prifiles:
427      code to compute profile-based cost by Gael Forget
428      (modifs in ecco, ctrl, autodiff)
429    o Benign bug fix in initialization (spotted by M. Mazloff) of
430      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
431    
432    checkpoint58c_post
433    o adjoint: finish NLFS adjoint and provide reference output in
434      verification/global_ocean.90x40x15/results_ad_nlfs
435    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
436      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
437      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
438      with SEAICE_CGRID defined.
439    o move calendarDumps from "data" to "data.cal" and clean-up the code
440      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
441    o add useEXF & useCAL flags (for now, set in hard-coded way)
442    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
443      (were missing in NH mode, and wrong in quasihydrostatic mode).
444      waiting for Chris updated version of calc_gw to add those CALLs.
445    o fix bug in quasihydrostatic S/R ;
446      add a test for this option: global_ocean.90x40x15.qshyd
447    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
448      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
449    o add on/off flag useOffLine for package OFFLINE
450    o seaice:
451      - modify advection so that it works also on the C-grid
452      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
453        problem in multi-tile runs with C-grid
454      - add flags for clipping ice velocities and/or masking solver forcing
455      - fix drag (ocean on ice) formulation and a bug that caused noise in the
456        C-grid solver
457      - added a few comments to seaice_diffusion.F
458      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
459        are now exclusive)
460      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
461        required re-ordering the code a little:
462       + make DAIRN global variable (defined in SEAICE)
463       + move computation of the viscosities eta and zeta into a new separate
464         routine (because I need to recompute them in seaice_ocean_stress.F)
465    
466    checkpoint58b_post
467    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
468      update output.txt of exp. aim.5l_cs.thSI
469    o various mnc cleanups and improvements:
470      + shrink lookup tables by factor of ~4
471      + better error reporting when running out of lookup space
472      + able to handle longer path/file names (up to 500 chars)
473    o adjoint:
474      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
475      - TBD: "hidden" mom_vecinv recomp. in dynamics
476    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
477     (allow to differentiate between forcing components using new integer flags:
478      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
479     and add new flag to put Dissipation tendency out of Adams-Bashforth.
480    o ecco
481      - enable trend removal from SSH anomaly obs.
482    o adjoint
483      - a fix for PmEpR when #undef EXACT_CONSERV
484      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
485      - try to fix "hidden" recomp. in forward_step for NLFS
486        (NLFS seems broken sometimes after I checked it in)
487    o seaice:
488     - add c-grid version of the dynamic solver:
489       + three new routines that are the c-grid substitute lsr, dynsolver
490         and ostres
491       + put a few fields that were local to dynsolver into global common
492         blocks, so that I can move the computation of stresses etc into
493         seaice_lsr (saves coding but may break the adjoint).
494     - replace more hardwired parameters by runtime parameters
495     - add ice masks that mask the rhs of the implicit solvers where there
496       is no ice (commented out in seaice_dynsolver, because i am not sure
497       if this works properly), eventually this should replace the clipping
498       of ice velocities in seaice_dynsolver to +/-40cm/s.
499    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
500      include it only where its needed
501    o move balancing of fluxes before the call of external_forcing_surf
502    o seaice:
503      - correct units of turning angles (now they are really in degrees)
504      - move computation of GWATX/Y out of main routine into dynsolver
505      - initialize GWATX/Y in seaice_init
506    o Apply mask on Fresh-Water flux (needed for SSH forcing).
507      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
508    o seaice: add runtime flags for turning angles (default to zero)
509    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
510      and trend from exf forcing and ctrl control adjustments
511    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
512      (since checkpoint57x_post)
513    o change the default rotation period to 86164.s = the Earth rotation
514    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
515      and based on a reference stratification. Tested within hs94.cs-32x32x5.
516    o seaice advection: add code for choosing between the default (2nd order
517      central differences) and multiDim advection schemes provided by
518      pkg/generic_advdiff
519    o seaice:
520      - removed all references to SEAICE_GRID.h fields from
521        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
522        (cubed-sphere configuration will change a little)
523      - grid computations in seaice_init are obsolete now.
524      - cleaned up code a little so that is easier to read (hopefully).
525      - added new (better?) discretizations of default advection and diffusion
526        (turn on with SEAICEuseFluxForm)
527      - replace 1 in 3d global fields by kSurface in growth.F
528      
529    checkpoint58a_post
530    o seaice:
531      - bug fix in advect.F
532    o shelfice:
533      - separate shelfice load anomaly from pload (breaks with time
534        dependent forcing), => introduce constant field shelficeLoadAnomaly.
535        Its default is 0., but it may be computed more cleverly from (unknown)
536        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
537        done offline. A good approximation of the pressure load anomaly is
538        necessary to avoid large initial adjustment processes underneath
539        deep-reaching shelfice.
540      - small fix in ISOMIP shelfice_thermodynamics
541      - add more sophisticated thermodynamics of Hellmer (1989), this is
542        now the default
543      - give a few constants more intuitive names
544    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
545      if bulk formulae are used in long integration (especially EmPmR). Turn
546      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
547      if balancePrintMean, the imbalance that is substracted is printed to
548      STDOUT.
549    o fix bug (typo) in obcs_apply_eta.F
550    o add a new package shelfice which enables us to model the circulation
551      underneath shelf-ice with draughts of hundreds of meters.
552     - works
553     - to do: + include improved thermodynamics
554              + check whether kSurfC (from model/inc/SURFACE.h) can be used
555                instead of new field kTopC
556              + can we use topoFile, Ro_surf and existing code in ini_depth.F
557                instead of new field R_shelfIce and new code in ini_depth.F
558                and ini_mask_etc.F?
559              + adjust vertical mixing schemes?
560    o seaice pkg:
561     - add a cpp-flag to include a simple formula for a salinity dependent
562       freezing point of sea water at the surface
563     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
564       meridional stresses are now different (and hopefully correct)
565    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
566       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
567       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
568    o pkg/diagnostics: add options and parameters for regional-statistics
569       diagnostics ; define regions by reading a region-mask from a file
570       (might add other options later)
571    o pkg/bulk_force:
572     - add option and parameters to use AIM surface-flux formulae.
573     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
574       others forcing fields (defined in PARM05, parameter file "data") are loaded
575       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
576     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
577     - use the right EXCH call for uwind,vwind (to work on CS-grid).
578     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
579       and parameters (note: calcWindStress replaces .NOT.readwindstress).
580     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
581    
582    checkpoint58
583    o add "--embed-source" option to genmake2 which, when the supporting
584      tools can be compiled (as determined by genmake2) will turn on the
585      embed_files package which then embeds the entire MITgcm source code
586      (*.[fFhc] + Makefile) used for the build within the executable
587      - requested by CNH but off by default
588      - adds a paltry <9MB to the mitgcmuv executable in most cases
589      - only writes the output when useEMBEDSRC in eedata is true
590    o clean up 3-dim. relaxation codes:
591      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
592      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
593      * Thanks to Tom Haine for testing!
594    
595    checkpoint57z_post
596    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
597      affects output (@ truncation level) of exp. plume_on_slope ; updated.
598    o fix the pickup behavior for obcs in combination with ptracers
599    o fix a bug in ptracers_external_fields_load
600    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
601      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
602    o transfered surface NH pressure to eta field (if exactConserv).
603    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
604         and update lab_sea output.txt file.
605    o completing 3-dim. relaxation code: additional term
606         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
607      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
608      * At compile time, in "EXF_OPTIONS.h" set
609          #define  ALLOW_CLIMTEMP_RELAXATION
610          #define  ALLOW_CLIMSALT_RELAXATION
611      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
612          tauThetaClimRelax3Dim = 15552000.0,
613          tauSaltClimRelax3Dim  = 15552000.0,
614      * 3 cases:
615          1) Use a constant-in-time 3-dim. field
616          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
617          3) Real-time relax. to time-evolving prescribed field
618    o Adding Laplacian-type smoothness constraint on
619      initial and boundary (forcing) controls (ic, bc)
620      * enable at compile-time via
621        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
622      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
623      * Absolute scale somewhat unclear so far
624      * no area weighting was included since no other cost term does so far
625    
626    checkpoint57y_post
627    First step for a NLFS adjoint
628    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
629    o new init. routines for calc_r_star, calc_surf_dr
630    o still need to deal with ini_masks_etc
631    o testreport seemed happy
632    checkpoint57y_pre
633    
634    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
635    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
636    o add new offset feature to offline pkg (plus minor cleanup)
637    o cfc fixes for final year of integration
638    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
639      be in GCHEM_OPTIONS).
640    
641    checkpoint57x_post
642    o fix testreport Pb in multiple test experiment.
643    o cleanup our namelist syntax in verification:
644      - make it more F95 standards compliant (some work still needed)
645      - allows the vast majority of our tests to work with gfortran
646    o Non-Hydrostatic:
647     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
648     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
649    o Allow to apply AB on T,S rather than on AB(gT,gS):
650     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
651     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
652       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
653     - need a "clever" read_pickup to restart from the other AB formulation
654    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
655    o remove some unused variables (reduces number of compiler warnings)
656    o adjoint
657      * Disable useVariableViscosity for adjoint for time being
658        (there are a number of extensive recomputations)
659      * Initialize certain variables needed for adjoint
660    
661    checkpoint57w_post
662    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
663                 fix the singleCpuIO RS version of MDSWRITEFIELD
664       and add a WARNING if using globalFiles=T with multi-processors.
665    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
666      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
667    o tracer advection scheme:
668      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
669       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
670       was not very convenient).
671      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
672       (further tests needed for the implicit DST & Flux-Limiter schemes).
673    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
674      and sRef for convenience, handy, when you want to initialize
675      ptracers in a large domain with a constant non-zero value. Also,
676      untangle ptracers_init.F a little.
677    
678    checkpoint57v_post
679    o change dome exp. to use variable viscosity in side-drag terms.
680    o remove all the files from the cfc_offline test since they are now
681      incorporated into tutorial_cfc_offline which has been producing
682      identical results for a few days of testing
683    o add new parameter: sideDragFactor to enable half-slip-side BC
684      and change side-drag S/R to use viscosity from mom_calc_visc
685      (can switch back by setting sideDragFactor=0.); affects results at
686      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
687       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
688    o vorticity & strain are now computed without masking, to account for
689      no-slip-side BC in variable viscosity calculation ; mask is applied
690      anyway later on, before computing advection/coriolis terms.
691    o modify exp4 to test new obcs support for reading from external files
692      and for passive tracers
693    o fix behavior of ptracers_monitor when monitor output is written to a
694      netcdf-file; still not independent of monitor.F (writes in the same
695      file).
696    o change default value of tRef (put a uniform, meaningful value for ocean
697      & atmos) and initialize sRef (was missing, as Martin mentioned).
698    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
699      to be proportional to enstrophy dissipation length.  Thus,
700       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
701      This is now consistent with Smagorinsky and with the manual.
702    
703    checkpoint57u_post
704    o OBCS and PTRACERS: add open boundary support for passive tracers
705      - either use homogenous (pseudo) v.Neumann conditions or prescribe
706        OB-values from file; this is not different from the way theta and salinity
707        are treated
708      - however, Orlanski-radiation conditions are not supported, and the model
709        will stop if you use pTracers and Orlanski at the same time.
710      - beefed up the rountine obcs_external_fields_load: now only those open
711        boundary values are overwritten with values from files for which there
712        are really files, otherwise the OB-fields remain untouched. This makes
713        it possible to use different OBs at different ends of the domain (as
714        with EXF)
715    o reduce number of exch calls in shap_filt (s2).
716    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
717      truncation level) 4/5 MLAdjust test results (11&12 digits match).
718    
719    checkpoint57t_post
720    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
721    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
722      same truncation, independent of the face number: affects affects several
723      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
724    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
725      note that biharmonic viscosity + no-slip was not tested in any experiment.
726    o fix bug in non-linear free-surf side-drag ; generate new output for
727      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
728    o make mnc honor the writeBinaryPrec flag for most kinds of output
729    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
730    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
731      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
732    o add brackets in multi-terms sum to get same truncation, independent of
733      the face number (manage to get exactly same value of gU,gV at the cs-edge)
734      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
735    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
736      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
737      a maximum grid-scale Reynolds number.  Also, changes all length calculations
738      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
739      Suggested values of viscosity parameters found in mom_calc_visc.
740      Many new viscosity diagnostics available.
741    
742    checkpoint57s_post
743    o Add clearing-house for viscosity calculations, mom_calc_visc and
744      correct numerous bugs in LeithD and Smagorinsky discretizations.  
745      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
746      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
747      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
748      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
749      The Strain-Tension form is now called with useStrainTensonVisc=.true.
750      ViscAhStrain and viscAhTension are now retired.
751    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
752    o In response to JMC's bug report, genmake2 now ignores any soft-links
753      that it finds in the *current* directory when searching for files.
754      Soft-links found in any other source directories will still work as
755      they did before.
756    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
757      a C routine to unlimit the stack size
758    o mnc-ify pkg/aim snapshot vars
759    o mnc-ify pkg/land as requested by Daniel
760    o various changes to mnc including:
761      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
762      - output can now be grouped so that all files within a group
763          change the ITER portion of their names in lock-step together
764      - can now read ("global") PER-FACE (in addition to PER-TILE) files
765          and works with both EXCH1 and EXCH2 (but needs more testing)
766      - writing works for all verification test cases w/ g77 on Linux
767    
768    checkpoint57r_post
769    o make MNC variable initialization happen earlier
770    o add diagnostics for (almost) each term of the momentum Eq.
771    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
772    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
773    o remove MINIMAL_TAVE_OUTPUT option ;
774      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
775    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
776      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
777    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
778    o add time-dependent SST, SSS control
779    o cost terms in ecco/ modularized (new cost_generic.F)
780    o cost_averages routines are modularized (new cost_averagesgeneric.F)
781    o new infrastructure for seaice model vs. obs misfits in seaice/
782      * driver from the_main_loop.F is seaice_cost_driver.F
783      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
784      * gradient check in Exp. 6a of natl_box_adjoint/
785    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
786      (see README file)
787    
788    checkpoint57q_post
789    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
790    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
791      - bug was reported by Jean-Michel and Ian Fenty
792    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
793      update exp. cpl_aim+ocn output.
794    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
795      Needed for high-res. runs with large global files
796      to be able to limit tapelev size
797    o Changed some tests for adjoint:
798      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
799      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
800      * global_ocean.90x40x15/ back to default 3-level checkpointing
801    o Modifications to enable scripted COMMON to MODULE conversion
802      * verification/OpenAD/code/ has necessary scripts and description;
803      * converts, compiles and runs successfully;
804    
805    checkpoint57p_post
806    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
807    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
808      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
809    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
810    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
811      (was already the case for dissipation with mom_vecinv,
812       and also the case for grad.PhiHyd when staggered-timeStep)
813      This will allow to put dissipation out-off the AB time-stepping.
814     Unfortunately, affects truncation error. Update output of exp. that "fails"
815      (cg2d matching number) and leave the others for later: front_relax(10),
816      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
817      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
818    
819    checkpoint57o_post
820    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
821      (2) its ready to be documented during the 20050801 DocFest
822    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
823      for ideal_2D_oce and lab_sea on linux_ia32_g77
824    o set to #undef CTRL_SET_OLD_MAXCVARS_30
825      in global1x1_tot/code_seaice_adj to access indices 32, 33
826      (worth another tag)
827    
828    checkpoint57n_post
829    o adding precip control xx_precip 32
830    o adding swflux control xx_swflux 33
831    o Replacing 10 forcing penalty cost routines by 1 generic.
832    o Implementing partitioning in time-mean and variable adjustment
833      for atmos. state.
834    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
835    o in natl_box_adjoint:
836      * updated exp 1 to 10
837        (but does not have time-mean vs. variable split results yet)
838    o updated global1x1/*_seaice_adj/
839      to incorporate latest changes
840    o enable useSingleCpuIO for mdsio vector routines
841      (applies in particular to tapelev I/O)
842    o removed inefficient K-loop in all active_file*control*.F
843    
844    checkpoint57m_post
845    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
846      and advect_cs (use EXCH-2 and standard cs-32 grid files).
847    o pkg/exch2: filling of face-corner halo regions is optional
848      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
849    
850    checkpoint57l_post
851     tag before updating tutorials (pre-release-2)
852    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
853       for output and interpolation of input fields onto model grid)
854    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
855       Affects results of exp. rotating_tank ; update output.txt.
856    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
857          and taking the square quantity and/or using a fraction-weight field.
858    o fix aim_diagnostics_init.F mate numbers.
859    o add mnc output capability to diagnostics/diagstat and update
860      our cvsignore files for the ACSII output generated
861    
862    checkpoint57k_post
863    o lab_sea now uses diagnostics package and provides a suite of
864      new EXF diagnostics output.
865    
866    checkpoint57j_post
867    o exf
868      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
869        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
870        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
871      * extended diagnostics output
872        - now includes all EXF variables
873        - hs, hl moved to common block
874        - separate S/R for diagnostics, called after ctrl vector is added
875        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
876        - EXFqnet contains true Qnet (i.e. includes qsw)
877      * updated verif. lab_sea, global_with_exf
878      * Rearranging hflux (exf_mapfields -> exf_getforcing)
879        to ensure that diagnostics sees a true EXFqnet
880    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
881    o diagnostics pkg: change pointers so that 1 diagnostic can be used
882      several times with different frequencies.
883    o mnc-ify the thsice package as requested by Daniel Enderton
884      - the monitor--MNC output needs work
885      - many attributes need to be added (most are currently blank)
886    o mnc-ify theaim_v23 package as requested by Daniel Enderton
887      - many attributes need to be added (most are currently blank)
888    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
889    o add Sadourny like discretization to the 4th.O vorticity advection scheme
890    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
891      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
892         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
893    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
894     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
895    
896    checkpoint57i_post
897    o Diagnostics package was changed: diagnostic allocation is now deactivated
898      by setting an empty file name in the namelist (used to be by setting 0 frequency)
899    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
900      add 1rst Order upwind vertical Shear.
901    o add a quick fix for A/B checkpointing in OFFLINE mode
902    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
903      end-run around the C/Fortran linking horror in eesup/src/timers.F
904    o added pkg/runclock: allows user to terminate run based on wall clock
905    o added non-hydrostatic scaling parameter: nh_am2
906    o pkg/my82: futile attempt to make results compiler-independent by adding
907      some "_d 0", etc. no effect.
908    o for mnc output, fill the 'T' coordinate var with myTime and create a
909      separate 'iter' variable for iteration count
910    o pkg/diagnostics:
911      add new capability: output of Global/Regional & per-level statistics ;
912      tested against monitor output (including land & thSIce) on various exp.
913    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
914    
915    checkpoint57h_done
916      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
917      data.diagnostics, data.gchem, data.ptracers) is done.
918    
919    o pkg/diagnostics: prepare for Global/Regional statistics.
920      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
921    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
922      and rename it: DIFFERENT_MULTIPLE
923    
924    checkpoint57h_post
925    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
926    o pkg/diagnostics: change output frequency, now in seconds (instead
927      of Nb of iterations). This requires to change data.diagnostics.
928    checkpoint57h_pre
929    
930    o in mnc, let the user create the output dir if both mnc_outdir_date
931      and mnc_outdir_num are false
932    o add fflags() to pkg/diagnostics which allows one to specify, on a
933      per-file basis, the file precision [default behavior is unchanged]
934    o added diagnostics to pkg/kpp, including computation of mixed layer
935      depth based on a temperature/density criterion
936    o updated verification/natl_box to test the new pkg/kpp diagnostics
937    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
938    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
939    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
940      not mnc -- this mistake was found by JMC and is now corrected
941    
942    checkpoint57g_post
943    o add Adams-Bashforth 3rd Order time stepping:
944      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
945      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
946    checkpoint57g_pre
947    
948    o make lambda[Theta,Salt]ClimRelax spatially varying
949      (default remains spatially uniform constant based on tau)
950    o added new control variables
951      * init. uVel, vVel, etanN
952      * lambda[Theta,Salt]ClimRelax
953    o separate masks used for ctrl_pack/unpack 'from write_grid' output
954      (suggested by G. Forget)
955    
956    checkpoint57f_post
957    o add parameter "baseTime" = model base time = time at iteration zero
958      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
959      account for baseTime shift
960    o move Coriolis arrays from PARAMS.h to GRID.h
961    checkpoint57f_pre
962    
963    o mnc-ifying the seaice package
964    o introduced an alternative length scale calculation for use in the limiting
965      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
966    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
967    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
968      as well as grad(vort3).  Made it compatible with both approximate form
969      for the cubed sphere and full form of these gradients.  Added flag
970      useFullLeith to select between approximate and full form.  
971    o add "d0" in getcon.F to reduce differences between compilers/platforms
972      update output.txt of exp. fizhi-gridalt-hs
973    o change port_rand funtion to allow to set the seed.
974    o fix obscure MNC bug involving conversion between reals and integers
975      - it caused no problems with certain (eg. gcc, ifc) compilers but the
976        new version is now more standards-compliant
977    o adjoint-related modifications
978      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
979      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
980      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
981    
982    checkpoint57e_post
983    o Adding eddy stress controls a la Ferreira et al.
984    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
985    
986    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
987      update output.txt of exp. fizhi-gridalt-hs
988    o add more "Z" dimensions and associated coordinate vars to MNC
989    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
990    o parameter calendarDumps: when set, approximate months (30-31 days) and years
991      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
992      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
993      months and years.  Requires pkg/cal.
994    o diagnostics: add pickup functionality
995      - off by default for backwards compatibility
996      - current version only uses MDSIO -- MNC will be added
997    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
998    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
999    
1000    checkpoint57d_post
1001    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1002    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1003      output from the diagnostics package
1004    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1005    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1006      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1007    o add coordinate variables to the MNC output from the diagnostics package
1008    o change MNC-flags default value: true when useMNC=TRUE
1009    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1010      the ability (off by default) to read the grid information using MNC
1011    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1012    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1013    o do snap-shot diagnostics at the middle of the time-interval (instead of
1014      at the end).
1015    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1016      new test for AIM with thSIce + slab-ocean
1017    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1018    o move state variable diagnostics to the beginning of the time step ;
1019      (note: still needs some work specially for snap-shot diagnostics)
1020      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1021    
1022    checkpoint57c_post
1023    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1024    o generate new output.txt files on faulks with g77 & the new -ieee option
1025    checkpoint57c_pre
1026    
1027    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1028      update output.txt of exp. global_ocean.90x40x15
1029    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1030      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1031    o add saltFlux(+File) forcing capability with periodicExternalForcing
1032    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1033    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1034    o improvements for the MNC output from DIAGNOSTICS:
1035      - correct handling of the unlimitied dimension
1036      - all dims now have associated coordinate variables
1037      - variables located at U, V, and Corner ("Z") points are now written
1038        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1039        *all* data points are output
1040    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1041    o added pkg/seaice/seaice_monitor.F
1042    o mdsio_readfield.F can now read files visible only to master MPI process.
1043    o pkg/seaice: some test code for ice-modified ocean stress
1044    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1045      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1046      spurious negative numbers for precipitation and humidity.  Will cause
1047      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1048    o pkg/ctrl/
1049      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1050        May be enabled via doPackDiag
1051      *  introduce z-scaling of
1052         + gradient (doZscalePack) and
1053         + control (doZscaleUnpack)
1054    o pkg/mdsio/
1055      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1056      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1057    
1058    checkpoint57b_post
1059    o simplify options in diagnostics_fill arguments (remove weird combinations)
1060    o fix MNC coordinate variables so that they now contain per-face index
1061      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1062      general, EXCH2 grids are only aligned to a "local" coordinate system
1063    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1064    o Implement instantaneous output within pkg diagnostics:
1065      setting a negative frequency in data.diagnostics produces
1066     "snap-shot" output (as opposed to time-average if freq > 0)
1067    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1068      NOTE: change ptracer diagnostics name: use 2 characters to work with
1069            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1070    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1071      becomes the coordinate variable for the 'T' dimension
1072    o add CF-style coordinate variables to MNC
1073      - just a first cut:  numbers are meaningless on the cubesphere and
1074        missing along the T axis but otherwise it works!
1075    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
1076    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
1077    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
1078      this is based directly on what the model compute, so that the content of
1079      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
1080    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
1081    o clean up build options files for SunOS, in particular
1082      - remove -traditional from xmakedepend
1083      - change -xarch=v9 to -xarch=native for f77
1084      - restore use of make (not gmake)
1085      - add CC=gcc if using g77
1086    o changes per discussion of AM, JMC, & EH3 today:
1087      - move redundant "grid" variables out of "state" -- in preparation of
1088        creating proper CF-style coordinate variables and in recognition
1089        that any/all grid variables can be easily copied (eg. w/NCO) from
1090        the grid files into any of the other NetCDF files
1091      - *always* output grid variables with MDSIO (this will eventually be
1092        changed)
1093      - output MNC grid file if useMNC is true
1094    o every instance of _END_MASTER() has been found and replaced with
1095      _END_MASTER( myThid ) in order to satisfy certain picky Sun
1096      preprocessors
1097    o re-arrange diagnostics pkg initialisation:
1098     - allow each package to extend the available diagnostics list
1099     - add some checking and fix small problems (multi-threaded, ...)
1100     - new S/R diagnostics_fill (replace fill_diagnostics):
1101       look through the short list of active diag. (instead of the long list)
1102       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
1103    
1104    checkpoint57a_post
1105    o this set of changes restores TAMC compatibility
1106      tested for global_ocean.90x40x15 adjoint on trough
1107      (what a pain)
1108    
1109    checkpoint57a_pre
1110    o some modifs in tools/build_options for sunos
1111    o call ctrl_pack for ctrl at end for optimcycle=0
1112    
1113    checkpoint57
1114    o add horizontal bi-harmonic viscosity for vertical velocity
1115      - new parameter viscA4W (defaults to viscA4)
1116      - affects only non-hydrostatic code
1117      - to be done: no-slip lateral boundary conditions
1118    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1119    o implement Implicit Vertical advection for pTracers
1120    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1121      (implemented also for implicit vertical diffusion & advection)
1122    o OBCS: extend application of tracer open boundary conditions
1123      to a strip beyond the boundary of width Olx/Oly
1124    o add call monitor to TAF set of required calls (flow directives)
1125      and include in natl_box_adjoint
1126    o untangle a few ifdefs related to cost, ctrl, autodiff
1127      untangel a few ALLOW_ECCO_OPTIMIZATION
1128    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1129      (theta2, salt2 in ecco_cost_weights)
1130    
1131    checkpoint56c_post
1132    o OBCS as control variables
1133      - update ctrl_ad_diff.list, obcs_ad_diff.list
1134      - remove balance of obcs controls from default
1135      - fix index bug nobcs in ctrl_init
1136      - fix dummy fields filen in ctrl_pack
1137      - add dummy weights for obcs
1138    o lsopt: comment out fort.94 output
1139    o optim:
1140      - remove unnecessary header files
1141      - adjusted namelists
1142      - add xerbla.F to Makefile
1143    o exf:
1144      - multiple modifications of exf_check_range
1145      - unit change in exf_init_runoff from [m/year] to [m/s]
1146    o mdsio:
1147      - i/o-vector change debugLevel from debLevA to debLevB
1148    
1149    checkpoint56b_post
1150    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1151      is called from DO_THE_MODEL_IO
1152      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1153      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1154      - clean up PTRACERS_WRITE_TIMEAVE a little
1155    o add another verification experiment that tests both the cfc-pkg and
1156      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1157      reactive tendencies treated inline with regular timestepping
1158    o testreport previously did a lousy job of comparing small numbers, so
1159      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1160      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1161      testreport.
1162    o ptracers_monitor: bug fix for MPI
1163    
1164    checkpoint56a_post
1165    o GCHEM: finish reorganizating the package
1166      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1167        (introduces another 3D-array for each passive tracer, but only if
1168        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1169        gchemTendency is not needed because the timestep is done separately)
1170      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1171      - GCHEM is now---more or less cleanly---separate from PTRACERS
1172      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1173        so clear to me how that should be done in a general way.
1174    o CFC: improve formatting of output in CFC_ATMOS
1175    o PTRACERS:
1176      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1177        that ALL experiments with ptracers enable can be checked. This makes
1178        GCHEM_MONITOR obsolete.
1179      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1180        monitorFreq
1181      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1182    o add PTRACERS (PTR0[1-5]) to testreport output
1183    o exf_check_range:
1184      * default changed to .TRUE.
1185      * will check values for niter0 if debLevA, every timestep if debLevB
1186      * STOP in exf_check_range if 'out of range'
1187      * range chosen generous to allow for potential extema
1188      TBD: a version with stricter range
1189           permitted range would be runtime parameters
1190    o GMredi:
1191      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1192      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
1193      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
1194    o GCHEM:
1195      - move call to GCHEM_FORCING_SEP, so that it is now called before
1196        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
1197      - introduced a useGCHEM runtime flag and applied it everywhere.
1198      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1199        this flag is now only visible within GCHEM-pkg routines.
1200      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1201        be replaced by a 3D array that is computed before thermodynamics; for
1202        this, the tracer ID iTracer had to be included into the parameter list
1203        of ptracers_forcing
1204      - set up forward_step to call gchem_forcing, that will replace
1205        gchem_forcing_int in ptracers_forcing
1206      - cleaning up
1207    o small cleaning of exch2: remove files that are also in eesupp/src
1208    
1209    checkpoint56
1210    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
1211    o mnc: cleanup "full" files--fixes out-of-memory problem
1212    o ECCO-GODAE
1213      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
1214      * fully merged and updated from SIO code
1215        windstress sign change affects
1216        - exf_inscal_[u/v]stress
1217        - sign of xx_tau[u/v] adjustments
1218        - signs in cost_scat
1219      * ctrl_get_gen: avoid update of tau[u/v] for first few days
1220      * natl_box_adjoint updated and compressed
1221      * 2-level checkpoint switch added
1222        (tested in EXP. 1 of natl_box_adjoint)
1223      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
1224    o SVD
1225      * first complete, non-hacked version for SVD calculations
1226      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
1227        performed via direct access files admtlm_vector.it????
1228        (via ctrl_[un]pack)
1229      * optimcycle is used for ARPACK iteration counter
1230        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
1231      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
1232        and add linear transforms where necessary
1233      * controls are initial/final SST, SSS (can be extended; need to check
1234        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
1235    o mdsio: filename info to both stderr, stdout
1236    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
1237      from sign change
1238    
1239    checkpoint55j_post
1240    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
1241      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1242    o add consistent build directories and .cvsignore files to verification
1243    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
1244    o make all subroutines 30 or less characters in length for certain older
1245      compilers to work (a thorough search only turns up two routines in
1246      pkg/ptracers)
1247    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
1248      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1249    
1250    checkpoint55i_post
1251    o change arrays for total vertical diffusivity (2.D if explicit,
1252      3.D if implicit) ; each ptracer uses its own background value.
1253    o added mnc/NetCDF output capability to ocn_compon_interf
1254      - added bits to verification/cpl_aim+ocn so that it can run on
1255        ITRDA and other clusters without the mpirun "-wd" option
1256    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
1257      configuration
1258    o give MNC the ability to create additional files rather than
1259      exceeding a specified file size limit "MNC_MAX_FILESIZE"
1260      - the default is just less than 2GB which is a practical limit
1261        on many systems
1262    o Compute the non-local term using either KPP vertical diffusivity (=default)
1263       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
1264    
1265    checkpoint55h_post
1266    o add verification test "vermix"
1267    o remove all the *_ioinc flags and replace with the single global
1268      outputTypesInclusive flag
1269    o allow to set a vertical profile of vertical diffusivity for T & S
1270    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
1271    o useMNC moved from data.mnc to data.pkg
1272    
1273    checkpoint55g_post
1274    o Renaming carbon AD experiments to comply with testreport conventions
1275    o Updating adjoint of Held-Suarez hs94.1x64x5
1276    o Fixing directives for non-ECCO forward_step, after ECCO directives
1277      have been fixed to avoid recomp. of do_oceanic_phys
1278      Works well for global_ocean.90x40x15,
1279      but recomp. issue remains for carbon
1280    o Updating adjoint output for natl_box_adjoint after
1281      pkg/ecco has been modified (see taga c55d_post)
1282    
1283    checkpoint55f_post
1284    o rename to timeave_init_fixed
1285    
1286    checkpoint55e_post
1287    o some delicate re-shuffle of store directives to avoid one
1288      extra call of do_oceanic_physics
1289      affects ecco_the_main_loop.F, do_oceanic_physics.F
1290      checkpoint_lev1_directives.h
1291    o NB: this may break global_ocean adjoint temporarily,
1292      but it is clear how to fix it. Will do later, need this now.
1293    
1294    checkpoint55d_post
1295    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1296    o ecco_cost_weights is modified to 1x1 runs
1297    o modifs to allow observations to be read in as
1298      single file or yearly files
1299    o enable to read exf forcing fields as either
1300      single file or yearly files (flag useExfYearlyFields)
1301    checkpoint55d_pre
1302    
1303    o switch between 2-level and 3-level checkpointing
1304    o add ability of MNC to write local and "partial" (eg. 2D slices where
1305      the full 3D field is never actually stored) arrays to NetCDF files
1306      with the correct (that is, the complete multi-dimensional) set of
1307      array indicies
1308      - used in mom_vecinv() to write the diagFreq output
1309      - tested (demonstrated) in verification/aim.5l_cs
1310    o further mnc-ification
1311      - add verification/lab_sea to the list with mnc setups
1312      - fix undefined mnc v-names in cd_code
1313      - add kpp to mnc output (both snapshot and timeave)
1314    o non-hydrostatic code
1315      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1316        in calc_gw.F
1317      - defaults to viscAh
1318      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1319        friction or Leith) in non-hydrostatic mode, as long as there is
1320        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1321    o pkg/cost
1322      extend simple cost functions to treat time mean quantities
1323      (T,U,V) via cost_accumulate_state from cost_tile
1324    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1325        be 2 times larger than the minimum size the advection scheme requires.
1326        now get a perfect conservation of salt in advect_cs test-exp (updated)
1327    o GGL90 (Gaspar's TKE mixed layer)
1328      - add horizontal diffusion of TKE, requires exchanges in
1329        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1330        default. In OPA there is no horizontal diffusion of TKE but the
1331        mixing coefficients are computed from a horizontal average of TKE of
1332        6 points or so. I think that diffusion has a little more physical
1333        justification.
1334      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1335        was in vain)
1336      - mask tke-variable in ggl90_init
1337    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1338    o fix biharmonic diffusion on CS-grid.
1339    o more obcs stuff
1340      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1341        for reading boundary values. This routine is called from
1342        obcs_prescribe_read
1343      - updated obcs_check
1344      - changed sponge layer relaxation parameter units for days to seconds
1345      - turned off sponge layer by default
1346      - changed argument list of OBCS_CALC to myTime+deltaTclock
1347      - fixed about 35 bugs in obcs_external_fields_load
1348    
1349    checkpoint55c_post
1350    o obcs stuff
1351      - new runtime flags useOBCSprescribe, useOBCSbalance
1352      - re-arranged obcs_calc
1353      - moved exf_getobcs to obcs_prescibe_read
1354        obcs_prescibe_read is called after ORLANSKI stuff
1355        and independent of it (executable can contain all).
1356      - updated obcs_check
1357      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1358        These may be necessary only if tangential velocities are
1359        prescribed at OB, not sure, needs testing.
1360    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1361      which simplifies the calls and passes the ifc check-bounds test
1362    
1363    checkpoint55b_post
1364    o add a 2D scalar, Z location, exchange_2 routine.
1365    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1366      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1367      affects advect_cs results (for the wrong reason): update output.txt
1368    o use a more standard discretization for biharmonic viscosity ;
1369     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1370      affects results of dome set-up: update output.txt
1371    o fix gad_advection.F (CubedSphere part), back to version 1.23
1372    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1373    
1374    checkpoint55a_post
1375    o merged code to
1376      * prescribe/read time-dependent open boundaries
1377        (works in conjunction with exf, cal)
1378      * sponge layer code for open boundaries
1379      * each boundary N/S/E/W now has its own CPP option
1380        (healthy for the adjoint)
1381    
1382    checkpoint55
1383    o up-to-date adjoint of previous breaks
1384      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1385      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1386      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1387      - carbon: * remove tr1-related adjoint verification
1388                * add ptracer as control variable
1389    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1390      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1391    
1392    checkpoint54f_post
1393    o in verification/carbin/ remove experiment related to
1394      ALLOW_PASSIVE_TRACER (array tr1 etc)
1395      code_ad/ input_ad/ results_ad
1396    
1397    o add two new packages
1398      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1399        + subject to optimization (memory)
1400      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1401        + subject to reordering (many GOTOs in the original code)
1402        + so far opps is called for every (i,j) point, and then operates in
1403          the vertical; one may want to reorder the scheme in order operate in
1404          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1405          fields)
1406    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1407      - all verification tests compile and run with linux_ia32_g77
1408      - defaults are compatible with current input files--nothing
1409        should change if you were not previously using MNC
1410      - MNC output has been added in numerous places (eg. timeave)
1411        but there are still a few writes not yet do-able with MNC
1412        (this is in progress)
1413      - flags now allow for either/or/both use of MDSIO and MNC and
1414        documentation will soon follow
1415      - numerous small formatting cleanups for ProTeX
1416    o add version info (via BUILD_INFO.h) to MNC and stdout
1417    
1418    checkpoint54e_post
1419    o add two new packages
1420      - pp81 (Packanowski and Philander, 1981), Richardson number and
1421        stratification dependent mixing
1422      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1423      - these scheme operate in a similar manner as KPP (without ghat, of
1424        course), however there is only one diffusivity that is used for both
1425        temperature and salinity (and passive tracers)ç
1426    o add offline package
1427    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1428      provided by Stephanie Dutkiewicz
1429    o genmake2: add ability to search for C compilers and cleanup test output
1430      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1431    
1432    checkpoint54d_post
1433    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1434    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1435      leading to additional shift by 5 days each year of integration
1436       (i.e. leading to considerable offset over the years)
1437    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1438    o start with no AB and no initial filtering (staggerTimeStep):
1439      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1440    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1441      (external loading & cpl import/export stay in forward_step.F)
1442    o update coupling interface to work with new staggerTimeStep
1443    o change MDSIO ptracers_pickup.
1444    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1445    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1446    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1447    
1448    checkpoint54c_post
1449    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1450      this affects (truncation error) output.txt of test-exp:
1451       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1452    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1453    o change Qnet to always be the net heat flux, (+upward).
1454      affects (truncation error) output of natl_box exp.: updated
1455    o define the max number of passive tracers in PTRACERS_SIZE.h
1456    o start to test mnc routinely in exp0
1457    o add sea-ice loading (sIceLoad) as a new forcing field.
1458    
1459    checkpoint54b_post
1460    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1461       impressive on Altix and Opteron systems)
1462    o diagnostics can now write NetCDF files through the mnc package
1463    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1464    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1465    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1466      affects (truncation error) output of lab_sea & natl_box exp.: updated
1467    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1468    
1469    checkpoint54a_post
1470    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1471    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1472    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1473    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1474      + internal_wave (shift in writing cg2d_ini_res)
1475    checkpoint54a_pre
1476    
1477    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1478      - modified verification/lab_sea and natl_box_adjoint accordingly
1479    
1480    checkpoint54
1481    checkpoint53g_post
1482    o prepare splitting of thermodynamics: store convect.counter in common block
1483    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1484      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1485    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1486    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1487    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1488    o restore adjointability
1489    
1490    checkpoint53f_post
1491    o modifications that affect AIM experiment results (update output.txt):
1492      - no advection of S at top interface Nr (pkg/generic_advdiff)
1493      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1494    o AIM pkg:
1495      - include stability function into surf.Flux derivative relative to Tsurf
1496      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1497    
1498    checkpoint53e_post
1499    o merged cylindrical coord configuration
1500    o added rotating_tank experiment
1501    checkpoint53e_pre
1502    
1503    checkpoint53d_post
1504    o faulks upgraded: re-generate output.txt that have changed:
1505       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1506    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1507    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1508    o added Sadourny discretization of Coriolis
1509      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1510      - re-enabled use of omega3 (useAbsVorticity)
1511    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1512      vector-invariant equations
1513      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1514    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1515      hopefully without new bugs
1516      - still to do: biharmonic friction for non-hydrostatic w
1517    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1518    o regenerated output for global_ocean_ebm (using -ieee)
1519    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1520      of mom_common/
1521      - simple re-arrangement of instructions within computing loop
1522    checkpoint53d_pre
1523    
1524    checkpoint53c_post
1525    o new version of coupler for AIM+thSIce and Ocean models
1526     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1527     - land: change Evaporation of snow
1528     - aim with thSIce: fix bug in snow-precip.
1529    o changes to calc_gw.F
1530     - bug fix for w^2 term near the bottom boundary
1531     - (hopefully) improve the lateral slip boundary condtions for use with
1532        partial/looped cells
1533      - because the bug fix changes two verification experiments anyway (exp5
1534        and plume on slope), change the lateral boundary condition from half slip
1535        to the value of no_slip_sides
1536    o ebm package wasnt quite up to the parallel task. Fixed that.
1537    o Adjoint of EBM package + verification
1538      * TLM OK
1539      * ADM not sufficient accuracy yet (needs further testing)
1540    
1541    checkpoint53b_post
1542    o Commiting new energy balance model to repository
1543      * package is pkg/ebm
1544      * verif. is verification/global_ocean_ebm
1545      * references are in ebm_driver.F
1546    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1547    C        Global thermohaline circulation. Part I:
1548    C        Sensitivity to atmospheric moisture transport.
1549    C        J. Climate 12(1), 71-82
1550    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1551    C        Global thermohaline circulation. Part II:
1552    C        Sensitivity with interactive transport.
1553    C        J. Climate 12(1), 83-91
1554    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1555    C        Destabilization of the thermohaline circulation
1556    C        by atmospheric eddy transports.
1557    C        J. Climate 7(12), 1870-1882
1558    o Will need long integration testing.
1559    checkpoint53b_pre
1560    
1561    o created pkg/mom_common in preparation for variable viscosity code
1562    o renamed and split ini_mnc_io
1563    o pkg/land: only liquid water can diffuse or run-off
1564    o AIM using land: soil wetness availability account for snow
1565    o added printMapIncludesZeros to EEPARMS namelist
1566    
1567    checkpoint53a_post
1568    o restore TAMC compatiility for exf_constants.h
1569      (no usage of _d in .h)
1570    o Additional storing in KPP in an attempt to fix
1571      TAMC problem with adjoint of KPP code.
1572      (no success...)
1573      Identical code works fine with TAF.
1574    o Fixed verification/natl_box_adjoint experiments.
1575      Initial conditions for Experiments 4 and 5 are now
1576      set to "SEAICE_initialHEFF=0", which is more reasonable,
1577      and hence gives results closer to that of Experiment 2.
1578      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1579    
1580    checkpoint53
1581    o stable checkpoint with up to date adjoint
1582      TLM tests only run for 1st grdchk at the moment. Its unclear if
1583      this is a code problem or a problem with resetting code for g_
1584      variables that is being autogenerated wrong.
1585      Otherwise:
1586       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1587       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1588         are both still in chaos following their security messes.
1589    
1590    checkpoint52n_post
1591    o various build (mostly genmake2) changes including:
1592      - ability to build/run more easily within Cygwin and MacOS X
1593      - more complicated Makefiles with a stronger dependence on Gnu Make
1594    o pkg/seaice modifications
1595      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1596        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1597        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1598      - changed proxy for geostrophic velocity and updated
1599        verification/lab_sea/results/* accordingly
1600      - removed ADI dynamic solver from pkg/seaice
1601      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1602        they caused a segmentation fault under certain circumstances
1603      - removed unused field WATR
1604    o bug fix in exf-package:
1605      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1606         now reflect that.
1607    o small fixes in the cal-package:
1608      - set reference date to first of January for the 'model'-calendar
1609      - failing of cal_CheckDate in cal_FullDate now actually results in a
1610        warning
1611    o small modifications in exf-package to increase flexibility:
1612      - change climtempfreeze from a constant to a runtime parameter that
1613        is specified in data.exf_clim (default = -1.9)
1614      - introduce runtime parameter windstressmax (default = 2.0) that is
1615        specified in data.exf
1616    o fix in pkg/thsice:
1617      - update Evap (Tsf changes) to be consistent with Latent heat flux
1618      - maintain snow precipitation unchanged (even if Tsf >=0).
1619     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1620    
1621    checkpoint52m_post
1622    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1623      this does not change any of the results, because myIter=0 in swfrac always
1624      lead to jwtype=2 (the default anyway), but the call makes little sense
1625      as a default
1626    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1627    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1628      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1629    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1630    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1631    o extending useSingleCpuIO option to work with new exch2 I/O format
1632      - old-style, missing-tile I/O is still accessible by defining CPP
1633        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1634    o monitor package can write to NetCDF files and/or STDOUT
1635    o fix re-definition bug in MNC_GRID_INIT_ALL()
1636    o doc/api_reference added
1637      - a framework for building an API Reference Manual using all
1638        the "protex" comments embedded in the code
1639      - see pkg/generic_advdiff, pkg/mnc for examples
1640    o MNC:
1641      - make myThid the last argument for all subroutines
1642      - new default for the grid files: NO halos
1643      - add useMNC and other run-time flags
1644      - separate per-file-group handling of the unlimited dimension
1645      - early initialization of MNC w/ flags read at the eeboot stage
1646        and lookup tables set in initialize_fixed
1647      - write all MNC output to a freshly-created directory
1648    o thermodynamics sea-ice (thsice) is now tested with testreport.
1649    o test exp. advect_cs: use the standard cs32 grid ; update output.
1650    o Added functionality to grdchk:
1651      pick global i,j,k position (or nearest wet) where to perform check.
1652    
1653    checkpoint52l_post
1654    o new land formulation:
1655      a) use ground enthalpy as prognostic variable to ensure exact
1656         energy conservation.
1657      b) account for water temperature and for latent heat of freezing
1658         in all processes (rain, run-off, ground storage)
1659      c) compute surface and ground temperature implicitly.
1660    o aim_v23 modification for new land model:
1661      a) Treat separately land / ocean / sea-ice surface fluxes
1662         to allow implicit computation of land & sea-ice surface temp.
1663      b) add snow precipitation.
1664    checkpoint52l_pre
1665    
1666    o fix problem (when 1 tile is empty) in min/max monitor.
1667    o fix bug in timeAve (u,vZetatave in common block)
1668    o no restoring terms under ice for pkg/seaice
1669    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1670    o bug fix for pkg/seaice pickups
1671    o change MNC call locations and add coordinate attributes
1672    o mask vorticity at the corner ; affects global_ocean.cs output
1673    o fix ini_curvilinear_grid ; test CS experiments with mpi
1674    o aim.5l_cs: modify sea-ice fraction input file ; update output
1675    o exf: Adding simple range check routine for exf fields after read
1676    
1677    checkpoint52k_post
1678    o removed top-level directory "diags"
1679      - we migrated these functions to pkg/timeave a long time ago
1680    o fixed bug introduced in pkg/monitor
1681    o accuracy ctrlprec = 32 insuffient for gradient checks using
1682      averaged fields (I/O via cost_averages)
1683      -> use ctrl.h in active_file*.F to control I/O precision.
1684    o paramter list of CALL ADTHE_MAIN_LOOP
1685    o added initial do_the_model_io to ecco
1686    o set all ...Freq to zero after cost_final
1687      taveFreq, dumpFreq, pChkptFreq
1688    o MAIN and ECCO differentiability restored
1689    
1690    checkpoint52j_post
1691    o fix nchklev in tamc.h for global_ocean...
1692    o Bringing flow and store directives up-to-date
1693    o Really weird thing!
1694      call do_the_model_io from the_main_loop with parameters
1695      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1696      TAF places a faulty re-call of initialise_varia
1697      after cost_final call which should not be there!
1698    checkpoint52j_pre
1699    
1700    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1701      error messages
1702    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1703    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1704      debug output
1705    o modfied mdsio_writefield.F to handle non-global files under exch2
1706    o update AIM Cubed-Sphere exp (aim.5l_cs):
1707      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1708    o update AIM Equatorial Channel exp:
1709      use standard aim_v23 pkg and change the SST fields to be more realistic.
1710    o globalFile now works with exch2
1711    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1712      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1713    o limit timeave output for hi-res integrations
1714    
1715    checkpoint52i_post
1716    o removed CPP_EEOPTIONS.h from verification/*/code
1717    o updated the tiling for global_ocean_pressure
1718    checkpoint52i_pre
1719    
1720    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1721      the old pkg/aim).
1722    
1723    checkpoint52h_pre
1724    o shortened offending lines in exch2_send_rx?.template
1725    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1726    o genmake2: add build & execute test for NetCDF code
1727    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1728      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1729    o added useSingleCPUIO flag to monitor.F and mon_out.F
1730    o added temporary hack for sea-ice dynamics on the cube:
1731      metric terms are ignored and it is assumed that
1732      there is no sea-ice on cube faces 1, 2, 4, and 5.
1733    
1734    checkpoint52f_post
1735    o added exch2 cube routines to pkg/exch2
1736    o modified hs94.cs-32x32x5 to use it
1737    o added new grid files to hs94.cs-32x32x5
1738    checkpoint52f_pre
1739    
1740    checkpoint52e_post
1741    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1742      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1743    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1744      to work with implicit vertical advection and AB ;
1745    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1746    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1747     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1748    checkpoint52e_pre
1749    
1750    o fix bug in impldiff when Nr=1 or Nr=2.
1751    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1752    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1753    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1754      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1755    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1756    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1757    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1758    
1759    checkpoint52d_post
1760    o re-tiled many expts to allow comparison in multi-processor mode
1761      - updated output accordingly
1762      - changed hs94.128x64x5 to use intial T from file rather than use the
1763        random number generator
1764    o add infrastructure in model routines for fizhi and gridalt packages
1765    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1766    o changes to permit hi-res, cubed-sphere, configuration
1767      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1768      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1769      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1770        of surface winds for the cube
1771      (A verification experiment, based on global_ocean.cs32x15, but with
1772       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1773       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1774       complete with example surface forcing files and matlab scripts to look
1775       at the output and compare it with that of global_ocean.cs32x15.)
1776    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1777       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1778       to conform to the common rule.
1779    o check-in the first version of the coupler + interfaces for multi-components
1780       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1781       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1782       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1783       - ocean and atmos. share the same horizontal grid (no interpolation).
1784       - exchanges between component and coupler is done in forward_step
1785    o new verification experiment, cpl_aim+ocn:
1786       coupled ocean - AIM atmosphere on cs32 grid.
1787    
1788    checkpoint52d_pre
1789    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1790    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1791    
1792    checkpoint52c_post
1793    o Fixing OPTIONS files for use of exf:
1794      - ALLOW_ECCO not needed
1795      - ECCO_CPPOPTIONS.h should not be included from
1796        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1797        as has been the case in the past
1798      - All cal/exf related options are currently set in
1799        single header file. Should remain so until we
1800        agree on a consistent new policy.
1801    o Removed all CPP options for cal package.
1802      cal has no more CPP options.
1803    o modified STOREs in GAD_ADVECTION
1804    o corrected key comp. for passkey
1805    
1806    checkpoint52b_post
1807    o new version: "thsice" of thermodynamic sea-ice pkg:
1808     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1809     - modify fluxes but do not change theta directly;
1810     - light cleaning of bulk_force pkg (still needed with thsice).
1811     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice

1819      (need info on NUMBER_OF_PTRACERS)
1820    o missing PTRACERS headers in some routines
1821    o default tamc.h in pkg/autodiff supposed to crash
1822      to ensure proper customization
1823    
1824    checkpoint52a_post
1825    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1826      - moved surfaceTendencyTice from pkg/seaice to main code
1827      - subroutine FREEZE_SURFACE now limits only surface temperature
1828        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1829        => new output.txt for global_ocean.cs32x15 & global_with_exf
1830      - keep the old version of FREEZE for backward compatibility;

1846    o this is the post-merge tag of the ecco-branch
1847      (needs another clean checkout and re-testing)
1848    o various natl_box_adjoint configs and results
1849      but no input fields

1858    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1859    
1860    checkpoint51t_post
1861    o this is the pre-merge tag of the ecco-branch
1862    
1863    checkpoint51s_post
1864    o cleanup: removed various obsolete #define-s
1865    o pkg/grdchk
1866      - renamed 'ph-grd 3' to 'grad-res'
1867      - merged from ecco-branch
1868        (remaining bug fixes for obcs gradient checks)
1869      - additional high-precision output for testreport
1870        (grep for 'precision_grdchk_result')

1891    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1892    
1893    checkpoint51p_post
1894    o create initial cd_code package
1895      - WARNING: the initialization of fields within packages
1896        is broken because INI_FIELDS (where READ_CHECKPOINT is
1897        called) is called *before* PACKAGES_INIT_VARIABLES.
1898        This seems to be backwards since
1899        1) its important to initially zero the entire field including
1900           the "halo" region
1901        2) zeroing needs to be done *before* reading pickup info
1902           and the pickup call might or might not happen in any
1903           particular run
1904      - this needs an overhaul for R2
1905    o cleanup verification/*/code/GMREDI_OPTIONS.h

1940      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1941      - subroutine FREEZE now limits only surface temperature
1942        (this means new output.txt for global_ocean.90x40x15,
1943         global_ocean.cs32x15, and global_with_exf)
1944    o added surface flux output variables to TIMEAVE_STATVARS

2037      - See verification/global_with_exf/README for usage example.
2038      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
2039        flags and modified pkg/seaice accordingly.
2040    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
2041        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
2042        non-local transport term.
2043    
2044    checkpoint51e_post

2118    o somewhat cleaned package initialisation sequence for
2119      ctrl/ cost/ ecco/ in packages_... routines
2120    
2121    checkpoint50g_post

2123      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
2124      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
2125        made the default because of faster convergence than ADI
2126    
2127    checkpoint50f_post
2128    o exf totally restructured

2147     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
2148       nearly a copy of kpp_transport_s
2149     - there is no analogue to SurfaceTendencyS, so I have to use
2150       gPtr(of the surface layer) instead
2151    o add a new platform SunFire+mpi (SunFire 15000) to genmake
2152    checkpoint50e_pre

2157    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
2158      analogous to the cg2d-related output.
2159    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
2160      so that writing to internal file fn (with length 512) fails.
2161    checkpoint50d_pre
2162    
2163    checkpoint50c_post
2164    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)

2174    
2175    checkpoint50b_post
2176    o store u*,v* in gU,V instead of in guNm1,gvNm1
2177    o in order to put the momForcing out of the Adams-Bashforth:
2178      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
2179      to timestep.F
2180    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays

2188    
2189    checkpoint50a_post
2190    o Bug fix for merging between c50 and KPP.
2191      ikey was passed from thermodynamics to kpp_calc via
2192      common block rather than being recomputed in kpp_calc,
2193      in contradiction with new key itdkey.
2194      New key ikppkey created, and tamc.h headers updated.
2195    
2196    checkpoint50
2197    - 2nd step of merge with ecco-branch:
2198      merge changes in ecco-branch back into main trunk

2208        (runtime) values.
2209      - in exf_getffields.F
2210        Reduce i-/j-loop to interior domain, discarding overlaps.
2211        That also fixes wrong TAF-key computations for key_1, key_2
2212        with bulf formulae.
2213      - exf_init.F modify #ifdef for exf_init_evap
2214      - exf_getffieldrec.F, ctrl_getrec.F
2215        The following INT-usages are not safe:
2216          fldsecs  = int(fldsecs/fldperiod)*fldperiod
2217          fldcount = int(fldsecs/fldperiod) + 1
2218        and were modified.
2219    o autodiff: checkpoint_lev...
2220      - updated storing for bulk formulae (some arrays were missing)
2221      - added state for seaice package
2222      - synchronized with main branch
2223    o DIVA:
2224      Modif.s in
2225      - the_main_loop.F
2226      - the_model_main.F
2227      and added cost_final_restore.F cost_final_store.F
2228      o With these changes, it is possible to fully separate
2229        the first forward run to compute the cost function (mdthe_main_loop)
2230        and adjoint runs over individual DIVA intervals (adthe_main_loop)
2231        into separate model executions.
2232        This enables better tuning of DIVA to given queue sizes.
2233      o Loss of cost function value in consecutive DIVA runs is
2234        fixed by storing to 'costfinal' file.
2235      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
2236        beginning/end of adjoint integration is accounted for.
2237      The current changes apply to TAF-1.4.26.
2238      TAF has one remaining bug, requiring one manual change
2239      (see MITgcm manual).
2240    o cal: synchronized between MAIN and ecco-branch
2241    
2242    checkpoint48i_post
2243    o Changes to restore differentiability of code w.r.t. previous tag
2244      (mostly adding new routines to make list and replacing
2245      pressure by totPhiHyd).
2246    o Updated and merged grdchk package
2247      - has both ADM and TLM checks
2248      - works for single- and multi-proc.
2249      - output cleaned
2250      - worked successfully for parallel DIVA
2251    o genmake:
2252      - Adding -platform=SP4
2253      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
2254    o Modif. for DIVA:
2255      ctrl_unpack should not be called in intermediate DIVA interval.
2256      (similar thing would apply for active files such as
2257      tbar, sbar, psbar, which should not be reinitialised;
2258      only relevant for ecco-branch)
2259    
2260    checkpoint48h_post
2261    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
2262    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
2263    o Added SEAICE_initialHEFF to pkg/seaice
2264    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
2265    
2266    checkpoint48g_post
2267    --- EOS:
2268    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
2269      store total Potential in totPhyHyd for diagnostics & EOS.
2270    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
2271    --- Pressure/geopotential gradient:
2272    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
2273    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
2274      ( changes results of global_ocean_pressure )
2275    o NLFS + z-coord.: add eta*Rho' contribution.
2276    o accurate phiHyd when using interface-W at the middle between 2 centers
2277     ( changes results of ideal_2D_oce )
2278    o includes r* 2nd term in potential gradient.
2279    
2280    checkpoint48f_post
2281    Merging from release1_p12:
2282    o Modifications for using pkg/exf with pkg/seaice
2283      - improved description of the various forcing configurations
2284      - added basic radiation bulk formulae to pkg/exf
2285      - units/sign fix for evap computation in exf_getffields.F
2286      - updated verification/global_with_exf/results/output.txt
2287    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
2288      (SBO) core products, including oceanic mass, center-of-mass,
2289      angular, and bottom pressure (see pkg/sbo/README.sbo).
2290    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
2291      to avoid negative values in shallow regions.
2292      - updated verification/natl_box/results/output.txt
2293      - updated verification/lab_sea/results/output.txt
2294    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
2295    o Added useSingleCpuIO option (see PARAMS.h).
2296    o Updated useSingleCpuIO option in mdsio_writefield.F to
2297      work with multi-field files, e.g., for single-file pickup.
2298    o pkg/seaice:
2299      - bug fix in growth.F: QNET for no shortwave case
2300      - added HeffFile for specifying initial sea-ice thickness
2301      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
2302    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
2303      kpp_transport_t.F, forward_step.F, and the_main_loop.F
2304    o pkg/seaice:
2305      - adjoint-friendly modifications
2306      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
2307    
2308    checkpoint48e_post
2309    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
2310    o dynamics: change definition of computational domain & adapt mom_fluxform
2311      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
2312    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
2313        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
2314        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
2315        global_ocean.90x40x15 global_with_exf global_ocean_pressure
2316        inverted_barometer solid-body.cs-32x32x1
2317      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
2318    
2319    checkpoint48d_post
2320    o in preparation for r*:
2321     a) use pre-computed gradient of hydrostatic potential:
2322        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
2323     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
2324        => affects results of glob_oce_pressure (different truncation error)  
2325      update output.txt of ideal_2D_oce & global_ocean_pressure
2326    
2327    checkpoint48d_pre
2328    o in preparation for r*:
2329      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
2330      pass the 2 comp. of the grad. as arguments to momentum S/R.
2331      but for the moment, only used if it does not change the results.
2332    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
2333    
2334    checkpoint48c_post
2335    Modifications in treatment of initial flux forcing controls
2336    to avoid extra storing of flux fields.
2337    
2338    checkpoint48c_pre
2339    o Added tidal_basin_2d experiment (currently 1D!)
2340    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
2341    
2342    checkpoint48b_post
2343    o r* coordinate added in #ifdef NONLIN_FRSURF block.
2344     (modification to pressure gradient not yet implemented)
2345    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
2346      (for U & V) that are used for vertical advection of momentum.
2347    
2348    checkpoint48a_post
2349    o In preparation for r*, use temp. array to compute vertical transport
2350       in flux-form momentum pkg. => change results of few test-exp.
2351      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
2352                        lab_sea, natl_box & plume_on_slope
2353    
2354    checkpoint48
2355    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
2356    
2357  checkpoint47j_post  checkpoint47j_post
