5      ==============================      ==============================
6    
7    o pkg/exf:
8      - implement A-grid / C-grid selection for wind-stress input files.
9      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
10      for now, in exf_bulk_largeyeager04.F only :
11      - change implementation for case where windspeed + 2. components wind-stress
12        are read-in. AND use rhoConstFresh to convert evap.
13    o pkg/seaice:
14      - use correct EXCH_UV for wind-forcing (on A-grid).
15      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
16        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
17    o pkg/exf:
18      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
19      EXF_INTERPOLATION:
20      - merge global_with_exf/code version of exf_interp_read.F
21        to the main code ;
22      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
23        reading the file ; Important: This options needs to be defined to recover
24        previous code.
25        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
26      - no longer loose real*8 precision along the way when using exf_iprec=64.
27    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
28      - change discretisation of evp-solver in order to avoid another exchange
29        (changes lab_sea) and clean up a little
30      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
31        help the adjoint (this also changes the results slightly)
32      - add a few "_d 0" where they had been missing in seaice_evp.F
33      - cleaning up: remove unused seaice_calc_rhs.F
34    o pkg/exf: some cleaning-up:
35      - change various "constants" into runtime parameters
36      - cleaned-up Large&Yeager04 routine which should eventually
37        replace exf_bulkformulae.F (changed names of S/R and CPP)
38        and merged various ALLOW_ATM_WIND options
39     only used with thsice pkg (in thsice_get_exf.F):
40      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
41        which are used when useStabilityFct_overIce=TRUE (= the default)
42      - change default values of ice & snow emissivity and scale downward LW
43        by ice & snow emissivity.
44    o pkg/thsice:
45     fix few little problems, in thsice_calc_thickn.F:
46      - growth vertically (and not laterally) if iceFrac == iceMaskMax
47      - melt laterally only if hIce < hThinIce (as the comments say)
48      and in thsice_extend.F:
49      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
50      - start to form ice as soon as the minimum ice-volume is reachable.
51     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
52      and cpl_aim+ocn
53    o pkg/kpp
54     - move computation of surface related input fields to KPP into a new
55       subroutine kpp_forcing_surf.F
56     - remove wrong (within bi,bj loops) EXCH calls.
57     - little cleaning (add argument myThid in last position, cvs header ...)
58     - for now, fix conservation problem by exchanging KPPviscAz (may not
59       be the best fix)
60    o pkg/seaice
61     - check for inconsistent evp parameter/cpp-flag combination
62     - remove leftover errIO flat for obsolete name list error handling
63    o OpenAD
64     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
65    
66    checkpoint59a
67    o pkg/seaice: some parameter clarifications and a little bit of clean up
68    o pkg/thsice: rename run-time parameters:
69       himin       -> hIceMin
70       himin0      -> hThinIce
71       hihig       -> hThickIce
72       i0          -> i0swFrac
73       transCoef   -> bMeltCoef
74       frac_energy -> fracMelting
75      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
76       with default values (for now) that do not change the results.
77      remove old version of thsice vars advection in pkg/seaice.
78    o in FFIELDS.h:
79      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
80      - make pLoad & sIceLoad always available (but still only used if
81         ATMOSPHERIC_LOADING is #define).
82    o pkg/kpp: replaced _KPP_RL with _RL
83    o bug fixes for vertical diffusivity computations when both KPP and
84        3D diffusivity arrays are used.
85    o pkg/seaice: fix bug in evp solver, while doing that
86      - change (improve?) discretization of stress computations for both
87        cgrid-lsr and evp solver
88      - add a new routine to compute strain rates
89      - the above changes lab_sea results
90      - add no slip conditions for evp solver (off by default), lsr-version
91        may follow
92      - fix exchange for shear at Z-points (does not change lab_sea)
93      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
94        (to force the user to pick a time step since there is not "safe" way
95        of choosing it)
96      - add principal stress diagnostics
97      - rearrange fields for evp a little to avoid having to call a: too many
98        exchanges and b: exchanges for stress trensor components which we do
99        not have.
100      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
101        of evp, complete rewrite for lsr case (latter is does not yet work
102        in all cases)
103    o pkg/kpp: add code to have mixing in shelf ice caverns
104      - add myThid to all kpp routines (long overdue)
105    
106    checkpoint59
107    o pkg/exf:
108      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
109        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
110      - move exf header files from lower_case.h to UPPER_CASE.h ;
111        add missing cvs Header & Name
112      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
113      - add namelist param. selectStressGridPosition, exf_monFreq
114      - retire many _CLIM routines, and remove data.exf_clim
115        + params moved to data.exf
116        + climsst, climsss now handled by exf_set_gen, i.e.
117          climss?period=0 refers to constant field,
118          climss?period=-12 to monthly forcing
119      - split up namelists in data.exf
120    o pkg/seaice:
121      - remove seaice_exch and seaice_exch_uv
122      - remove superfluous exchange of theta
123      - add myThid to seaice_budget_ocean/ice
124      - add new interface for atmospheric wind forcing (C-grid only)
125        + new routine
126        + two new field (taux, tauy for stress over ice)
127        + removed one global field (DAIRN) for C-grid case only
128    o pkg/thsise
129      - 2nd set of modifs for thsice adjoint in conjunction with exf
130    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
131    
132    checkpoint58y_post
133    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
134      vertical diffusivity, similar to that in MOM4; turned on using
135      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
136      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
137    o Added capability for 3D specification of background vertical diffusion
138      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
139      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
140      "data" file that contains the 3D vertical diffusivity coefficients.
141    o ice dynamics (pkg/seaice) with thsice thermodynamics:
142      - add code within pkg thsice to advect & diffuse sea-ice fields
143      similar to (and will replace) what has been added in  seaice_advdiff.F,
144      but: - conserving Mass, Heat & Salt.
145           - better when using non-linear advection scheme (not yet fully tested)
146           - can also be used in atmospheric set-up (for now, only the diffusion).
147    
148    checkpoint58x_post
149    o IO option for global-file compact format:
150      - add options when generating topology (utils/exch2/matlab-topology-generator)
151      - add I/O capability (pkg/mdsio).
152      - adapt utils/matlab/rdmds.m to read this format.
153      for now long-line format not yet supported by pkg/mdsio (& exch2).
154    o shelfice: add a few diagnostics
155    
156    checkpoint58w_post
157    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
158      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
159      (and replace horiVertRatio in NH code).
160      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
161                         and tutorial_plume_on_slope (sensitive to truncation)
162    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
163      directly to drive seaice model (C-grid only)
164    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
165     - reintroduce computation of wind from stress,
166     - compute tau (in exf_bulkformulae.F) from windstress averaged to
167       mass points to avoid tau = 0
168     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
169    o rdmnc.m: make it work with "global" files created with gluemnc
170    o rdmnc.m : some improvements in dealing with singleton dimension
171      (tested on all testreport mnc output files).
172    o genmake2: disable pkg/profiles if netcdf test fails.
173    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
174    o move call to cal_readparms up to make calendar parameters/variable available
175      to all packages
176    
177    checkpoint58v_post
178    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
179      useDynP_inEos_Zc tested.
180    o pkg/exf: changes to properly interpolate/mask/scale initial fields
181    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
182      and portions thereof.  See read_cs.txt for description and examples.
183    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
184      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
185      following the great-circle arc between those 2 points.
186    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
187      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
188    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
189     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
190     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
191     - still needs work (not working with some options ; efficiency to improve)
192       and serious testing.
193     - use this scheme for temperature & salinity in 2 advection test exp.:
194       advect_xy & advect_xz, respectively.
195    
196    checkpoint58u_post
197    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
198    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
199    o testreport: add option "-skipdir" to skip some test.
200    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
201      momentum calculation.
202    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
203    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
204      remove checkpoint.F and the_correction_step.F (no longer used);
205      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
206    o add option (linFSConserveTr) to correct for tracer source/sink due to
207      Linear Free surface
208    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
209    o pkg/thsice: fix reading mnc-pickups
210    
211    checkpoint58t_post
212    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
213    o pkg/mdsio:
214     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
215       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
216       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
217     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
218     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
219       either MDS_READ_FIELD or MDS_WRITE_FIELD )
220     - new S/R (to replace MDSWRITEMETA), which allows to write more
221       informations (variable names, time ...) to meta files.
222     - modify rdmds.m to give back the meta file content.
223    o pkg/diagnostics: change vertical interpolation to be safer, and more
224       flexible (define p-levels to interpolate to in data.diagnostics);
225      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
226       diagnostic pointer.
227    o pkg/seaice: more cleaning up of seaice_growth, added many comments
228    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
229    o fix multi-category seaice:
230     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
231       SEAICE_MULTICATEGORY
232     - fix short wave heat flux
233    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
234       and allow to use EVP solver. Change forward lab_sea: test both EVP
235       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
236    o Initial check-in of lab_sea adjoint
237      (very similar to natl_box_adjoint/code_seaice)
238      * used C-grid and EVP solver
239      * used KPP, GM/Redi
240      * uses inAdExact=.TRUE.
241      * gradient checks fail for both ADM and TLM
242        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
243        f.d. gradients actually seem more problematic than ADM, TLM gradients;
244        issue is related to forward mismatch between g77 an ifort
245    o pkg/seaice: overhaul of thermodynamics
246     - growth.F and groatb.F are replaced by new routine seaice_growth.F
247     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
248     - move a few global fields out of SEAICE.h into seaice_growth.F and
249       make them 2D (FICE/QNETO/ ...)
250     - remove FO (it is the same as QNETO)
251     - introduce a few local fields to avoid modifying external fields such
252       as atemp, etc.
253    
254    checkpoint58s_post
255    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
256      changed exf_set_gen.F so that
257        genperiod=0 means input file is one time-constant field and
258        genperiod=-12 means input file contains 12 monthly means
259    o CG2D: use pre-computed solver main-diagonal (stored in common block);
260      this affects truncation error ; generate new output file for exp. which
261      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
262        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
263        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
264        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
265        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
266        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
267    o start implementation of deep-atmosphere and anelastic formulation
268    o verification: remove 2nd copy of input files and use script "prepare_run"
269      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
270    o mom_common/vecinv/fluxform: fix a few initialisation isssues
271    o profiles: fix for multithreaded case
272    
273    o diagnostics: rename few diags:
274      s/'PRESSURE'/'RCENTER '/g
275      s/'TICE    '/'oceFreez'/g
276      s/'TAUX    '/'oceTAUX '/g
277      s/'TAUY    '/'oceTAUY '/g
278      s/'SWFLUX  '/'oceQsw  '/g
279      s/DIFx/DFxE/g
280      s/DIFy/DFyE/g
281      and add few ocean-forcing diagnostics:
282      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
283    o modifications to pkg/seaice/growth.F and budget.F, which change results of
284      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
285      as actual snow thickness.  It now refers everywhere to effective snow
286      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
287    
288    checkpoint58r_post
289    o modifications to pkg/seaice/growth.F, which change results of
290      lab_sea experiment: fixes pertain to melting snow over open water, to
291      masking EVAP under sea ice, and to using the correct AREA variable for
292      computations of EVAP, PRECIP, HSNOW, and GHEFF
293    o add ability to read bathy, salt, and theta using MNC (off by def)
294    o add flooding algorithm and advection of HSNOW for pkg/seaice;
295      both are turned off by default and do no change any results
296    o seaice advection with pkg/thsice: a step toward the use of non-linear
297      advection scheme, but #ifdef or commented out for now (requires more EXCH).
298    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
299      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
300      in natl_box (affects results @ truncation level: update output.txt)
301    o multi-threading and IO:
302      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
303      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
304        (needed to work with SingleCpuIO): tested in all verif. exp.
305    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
306      affects the results (but none of the verification test uses this scheme).
307    o Adding some pkg/diagnostics capability to pkg/seaice
308      (will certainly be subject to changes)
309    o ctrl: adding new control variables:
310      lwflux, lwdown, evap, snowprecip, apressure, runoff
311    
312    checkpoint58q_post
313    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
314      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
315      high_res_cube configuration by 4% on Columbia.
316    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
317      add (in global_with_exf/code) a version of EXF_INTERP_READ without
318      dynamical allocation (seems to work in multi-threaded).
319    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
320      single CPU io) so that TAF does not have to see EESUPPORT.h
321    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
322    
323    checkpoint58p_post
324    o obcs: stop if obcs is used with useCDscheme = .true.
325    o shelfice:
326     - fix a sign error so that no slip at shelfice interface works
327     - remove stop for combination non-hydrostatic code and shelfice. That does
328       not mean, that the results are correct, but at least they are numerically
329       stable
330    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
331    o added adjoint exch routined for all exch*3d* routines
332      and updated flow directives
333    
334    checkpoint58o_post
335    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
336      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
337    o change controling S/R for writing pickup file (new S/R do_write_pickup)
338      and clean-up reading/writing of pickup files.
339    o fix local version of read/write pickup (NH part) in rotating_tank/code
340    o simplify EXCH interface:
341     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
342     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
343    o added the regrid package
344    o shelfice:
345     - add a simple boundary layer scheme to reduce noise
346     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
347    
348    checkpoint58n_post
349    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
350       local variable (not in common block).
351    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
352      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
353      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
354        to work with SingleCpuIO.
355    o add "_d 0" to real constant of pkg/cfc subroutines ;
356       update exp. cfc_exemple & tutorial_cfc_offline output files.
357    o multi-threading and IO:
358      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
359        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
360      - barrier before and after reading.
361      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
362      - avoid using MDS_WRITELOCAL for LAND pkg output.
363      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
364        common-block variables ; Allows multi-threading with master-thread IO.
365    o change default MAX_NO_THREADS from 32 to 4 ;
366      and stop cleanly when MAX_NO_THREADS is too small.
367    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
368    
369    checkpoint58m_post
370    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.

372    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
373       keep global_ocean.90x40x15 (for AD testing) with former secondary test
374       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
375    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
376        add MITgcm_tutorials (= code + all the tutorials)

378    o consistent with addition of ptracer and ssh in pkg/profiles
379    o profiles: adding ptracer and ssh
380    o testreport: change multi-test output-file name
381      (from output.txt.{name} to output.{name}.txt)
382    o profiles: now ok for mutli-tiles case
383    o seaice: add 4 parameters for different advection schemes for area,
384      (effective) seaice thickness, enthalphy, and snow height. Their default
385      is the standard parameter SEAICEadvScheme
386    o calc_gw:
387     - add cosFacU in zonal viscous flux (harmonic.visc.).
388     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
389       of tutorial_plume_on_slope.
390    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
391    o calc_gw: true flux-form, account for horizontal grid spacing.
392      update rotating_tank results, but not plume_on_slope (affected at
393      truncation level, 11 digits).
394    
395    checkpoint58l_post
396    o calc_gw:
397     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V

399     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
400    o commit code to make SST/SSS weights spatially variable
401      (based on either variable in-situ or variable initial T/S weights)
402    o pkg/ecco:
403      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
404        now based on horizontally varying weights wthetaLev, wsaltLev

411      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
412    
413    checkpoint58k_post
414    o testreport:
415     - always build in dir. "build" (if not there, mkdir build instead of building
416       & running in input)
417     - run in dir run (if it exists), in build otherwise.
418     - call prepare_run (if input/prepare_run exists)
419     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
420    o pkg/exf modifications to interpolation and rotation routines for more
421       reasonable treatment of North Pole singularity: for tracers North Pole
422       value is set to northernmost zonal-mean value, for zonal velocity it is
423       set to zero, and for meridional velocity it is set to northernmost value.
424    o pkg/exf/exf_check_range.F
425     - add tile index to diagnostics and move stop statement to the very
426       end of the routine.
427    o pkg/diagnostics: (diagnostics_main_init.F)
428      define title of isomorphic variables according to the current config.
429    o pkg/thsice with pkg/seaice dynamics:
430    - fix domain of computation (interior only, required for exf) and do exchanges
431    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
432    o towards a standard way of dealing with multi-threading in MONITOR
433      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
434    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
435       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
436    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
437    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
438    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
439       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
440    o tracer advection:
441     - clean-up and simplify calc_common_factors.F
442     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
443       advection subroutine (but still not used within DST advection S/R)
444    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
445    
446    checkpoint58j_post
447    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
448      from file (collects calls previously in FORWARD_STEP)
449    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
450    o adjoint store dir. adjusted accordingly
451    o genmake2
452      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
453    
454    checkpoint58i_post
455    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
456      on wind stress (SEAICEstressFactor defaults to 1.)
457    o Total number of Timers is finite (<=40): comment out 2 non-essential one
458      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
459    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
460      on CS-grid: no longer loosing mass.
461    o exf & curvilinear-grid: no longer modify longitude xC & xG.
462    o pkg/ggl90: fix sloppy output and fix a bug
463    o pkg/seaice: added SEAICEuseEVPpickup parameter
464      - Set to false in order to start EVP solver with
465        non-EVP pickup files when using SEAICEuseEVP
466      - fix sign error in diffusion in seaice_calc_rhs
467    
468    checkpoint58h_post

470      o replace hFacC by _hFacC at various places
471      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
472      o add non-self-adjoint cg2d_nsa
473      o update autodiff support routines
474      o re-initialise hfac after ctrl_depth_ini
475      o works for 5x5 box, doesnt work for global_ocean.90x40x15
476    * Adding verification for 5x5 box (4-layer) bottom topography control
477    
478    checkpoint58g_post
479    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
480       used for mean seasonal cycle, mean diurnal cycle); add an example
481       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
482    o pkg/ggl90:
483      - add parameter (minimum surface kinetic energy)
484      - fix bug (avoiding division by zero)
485    o couple pkg/thsice to pkg/seaice:
486      - modify advection in seaice to accomodate new scalar fields to be advected
487      - only muliDimAdection scheme work with seaice/thsice
488      - mapping of thsice-variables to seaice-variables, back and forth
489      - does not break the verification experiments, but does not give the
490        desired results either
491    o pkg/seaice
492      - make (default) second order advection a bit less confusing?
493    
494    checkpoint58f_post
495    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
496      to pkg/seaice):
497      - new routines thsice_map_exf and thsice_get_exf provide the interface
498      - add an additional formal parameter to thsice_solve4temp
499    o pkg/exf:
500      - add new fields wspeed, snowprecip (to be able to couple to thsice)
501      - correct Stefan-Boltzmann constant
502      - new parameter for longwave surface emittance
503      - separate some stuff from exf_bulkformulae into new routines  
504        exf_radiation, exf_wind
505      - add new parameters and constants: longwave emissivity for ocean, ice
506        and snow, evaporation parameters over ice
507      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
508        either wind from stress or stress from wind
509    o pkg/thSIce:
510    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
511    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
512       and THSICE_CALC_THICKN
513    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
514    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
515      to make debugging easier.
516    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
517    o pkg/bulk_force:
518      - clean-up comments and parameters ;
519      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
520    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
521      generate new output for test-experiment: aim.5l_cs.thSI
522    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
523      testreport accordingly
524    
525    checkpoint58e_post
526    o SEAICE_CGRID adjoint done
527    o R_STAR adjoint implemented.
528      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
529      * need to sort out init. of h0facc, etc.
530    o Make pkg/profile fully independent of ecco,cost, etc. stuff
531      to be able to use it in pure forward.
532    
533    checkpoint58d_post
534    o upgrade simple test-experiment to tutorial example:
535     step.1: duplicate the experiment and (step.2) will remove the old copy.
536      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
537      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
538      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
539      tutorial_global_oce_biogeo    <- copy of dic_example
540      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
541      tutorial_plume_on_slope       <- copy of plume_on_slope
542      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
543      tutorial_global_oce_optim     <- empty for now (David ?)
544      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
545     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
546    o correct a sign problem in cost_scat.F
547    o obcs and ptracers: fix boundary conditions for advections schemes
548      with larger stencil
549    o thsice adjoint: start
550    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
551      completeness
552    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
553      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
554    o ptracers adjoint:
555      * avoid extensive recomputatations
556      * fix missing re-init. of gptr (missed by TAF)
557    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
558      me to turn off the excessive output to STDOUT that this package produces
559    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
560      and add those terms in Vector-Invariant formulation.
561    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
562      if the control period (xx_hfluxperiod etc) is 0
563    o in profiles pkg, clean routines and fix details
564    o in ecco pkg, reading ssh data:
565      fix problem in case the model does not start at iter0=0
566    o fix mnc-pickup/restart for ptracers
567    o new package prifiles:
568      code to compute profile-based cost by Gael Forget
569      (modifs in ecco, ctrl, autodiff)
570    o Benign bug fix in initialization (spotted by M. Mazloff) of
571      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
572    
573    checkpoint58c_post
574    o adjoint: finish NLFS adjoint and provide reference output in
575      verification/global_ocean.90x40x15/results_ad_nlfs
576    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
577      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
578      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
579      with SEAICE_CGRID defined.
580    o move calendarDumps from "data" to "data.cal" and clean-up the code
581      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
582    o add useEXF & useCAL flags (for now, set in hard-coded way)
583    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
584      (were missing in NH mode, and wrong in quasihydrostatic mode).
585      waiting for Chris updated version of calc_gw to add those CALLs.
586    o fix bug in quasihydrostatic S/R ;
587      add a test for this option: global_ocean.90x40x15.qshyd
588    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
589      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
590    o add on/off flag useOffLine for package OFFLINE
591    o seaice:
592      - modify advection so that it works also on the C-grid
593      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
594        problem in multi-tile runs with C-grid
595      - add flags for clipping ice velocities and/or masking solver forcing
596      - fix drag (ocean on ice) formulation and a bug that caused noise in the
597        C-grid solver
598      - added a few comments to seaice_diffusion.F
599      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
600        are now exclusive)
601      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
602        required re-ordering the code a little:
603       + make DAIRN global variable (defined in SEAICE)
604       + move computation of the viscosities eta and zeta into a new separate
605         routine (because I need to recompute them in seaice_ocean_stress.F)
606    
607    checkpoint58b_post
608    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
609      update output.txt of exp. aim.5l_cs.thSI
610    o various mnc cleanups and improvements:
611      + shrink lookup tables by factor of ~4
612      + better error reporting when running out of lookup space
613      + able to handle longer path/file names (up to 500 chars)
614    o adjoint:
615      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
616      - TBD: "hidden" mom_vecinv recomp. in dynamics
617    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
618     (allow to differentiate between forcing components using new integer flags:
619      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
620     and add new flag to put Dissipation tendency out of Adams-Bashforth.
621    o ecco
622      - enable trend removal from SSH anomaly obs.
623    o adjoint
624      - a fix for PmEpR when #undef EXACT_CONSERV
625      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
626      - try to fix "hidden" recomp. in forward_step for NLFS
627        (NLFS seems broken sometimes after I checked it in)
628    o seaice:
629     - add c-grid version of the dynamic solver:
630       + three new routines that are the c-grid substitute lsr, dynsolver
631         and ostres
632       + put a few fields that were local to dynsolver into global common
633         blocks, so that I can move the computation of stresses etc into
634         seaice_lsr (saves coding but may break the adjoint).
635     - replace more hardwired parameters by runtime parameters
636     - add ice masks that mask the rhs of the implicit solvers where there
637       is no ice (commented out in seaice_dynsolver, because i am not sure
638       if this works properly), eventually this should replace the clipping
639       of ice velocities in seaice_dynsolver to +/-40cm/s.
640    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
641      include it only where its needed
642    o move balancing of fluxes before the call of external_forcing_surf
643    o seaice:
644      - correct units of turning angles (now they are really in degrees)
645      - move computation of GWATX/Y out of main routine into dynsolver
646      - initialize GWATX/Y in seaice_init
647    o Apply mask on Fresh-Water flux (needed for SSH forcing).
648      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
649    o seaice: add runtime flags for turning angles (default to zero)
650    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
651      and trend from exf forcing and ctrl control adjustments
652    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
653      (since checkpoint57x_post)
654    o change the default rotation period to 86164.s = the Earth rotation
655    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
656      and based on a reference stratification. Tested within hs94.cs-32x32x5.
657    o seaice advection: add code for choosing between the default (2nd order
658      central differences) and multiDim advection schemes provided by
659      pkg/generic_advdiff
660    o seaice:
661      - removed all references to SEAICE_GRID.h fields from
662        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
663        (cubed-sphere configuration will change a little)
664      - grid computations in seaice_init are obsolete now.
665      - cleaned up code a little so that is easier to read (hopefully).
666      - added new (better?) discretizations of default advection and diffusion
667        (turn on with SEAICEuseFluxForm)
668      - replace 1 in 3d global fields by kSurface in growth.F
669      
670    checkpoint58a_post
671    o seaice:
672      - bug fix in advect.F
673    o shelfice:
674      - separate shelfice load anomaly from pload (breaks with time
675        dependent forcing), => introduce constant field shelficeLoadAnomaly.
676        Its default is 0., but it may be computed more cleverly from (unknown)
677        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
678        done offline. A good approximation of the pressure load anomaly is
679        necessary to avoid large initial adjustment processes underneath
680        deep-reaching shelfice.
681      - small fix in ISOMIP shelfice_thermodynamics
682      - add more sophisticated thermodynamics of Hellmer (1989), this is
683        now the default
684      - give a few constants more intuitive names
685    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
686      if bulk formulae are used in long integration (especially EmPmR). Turn
687      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
688      if balancePrintMean, the imbalance that is substracted is printed to
689      STDOUT.
690    o fix bug (typo) in obcs_apply_eta.F
691    o add a new package shelfice which enables us to model the circulation
692      underneath shelf-ice with draughts of hundreds of meters.
693     - works
694     - to do: + include improved thermodynamics
695              + check whether kSurfC (from model/inc/SURFACE.h) can be used
696                instead of new field kTopC
697              + can we use topoFile, Ro_surf and existing code in ini_depth.F
698                instead of new field R_shelfIce and new code in ini_depth.F
699                and ini_mask_etc.F?
700              + adjust vertical mixing schemes?
701    o seaice pkg:
702     - add a cpp-flag to include a simple formula for a salinity dependent
703       freezing point of sea water at the surface
704     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
705       meridional stresses are now different (and hopefully correct)
706    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
707       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
708       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
709    o pkg/diagnostics: add options and parameters for regional-statistics
710       diagnostics ; define regions by reading a region-mask from a file
711       (might add other options later)
712    o pkg/bulk_force:
713     - add option and parameters to use AIM surface-flux formulae.
714     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
715       others forcing fields (defined in PARM05, parameter file "data") are loaded
716       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
717     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
718     - use the right EXCH call for uwind,vwind (to work on CS-grid).
719     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
720       and parameters (note: calcWindStress replaces .NOT.readwindstress).
721     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).

724    o add "--embed-source" option to genmake2 which, when the supporting
725      tools can be compiled (as determined by genmake2) will turn on the
726      embed_files package which then embeds the entire MITgcm source code
727      (*.[fFhc] + Makefile) used for the build within the executable
728      - requested by CNH but off by default
729      - adds a paltry <9MB to the mitgcmuv executable in most cases
730      - only writes the output when useEMBEDSRC in eedata is true
731    o clean up 3-dim. relaxation codes:
732      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
733      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
734      * Thanks to Tom Haine for testing!
735    
736    checkpoint57z_post
737    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
738      affects output (@ truncation level) of exp. plume_on_slope ; updated.
739    o fix the pickup behavior for obcs in combination with ptracers
740    o fix a bug in ptracers_external_fields_load
741    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
742      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
743    o transfered surface NH pressure to eta field (if exactConserv).
744    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
745         and update lab_sea output.txt file.
746    o completing 3-dim. relaxation code: additional term
747         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
748      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
749      * At compile time, in "EXF_OPTIONS.h" set
750          #define  ALLOW_CLIMTEMP_RELAXATION
751          #define  ALLOW_CLIMSALT_RELAXATION
752      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
753          tauThetaClimRelax3Dim = 15552000.0,
754          tauSaltClimRelax3Dim  = 15552000.0,
755      * 3 cases:
756          1) Use a constant-in-time 3-dim. field
757          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
758          3) Real-time relax. to time-evolving prescribed field
759    o Adding Laplacian-type smoothness constraint on
760      initial and boundary (forcing) controls (ic, bc)
761      * enable at compile-time via
762        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
763      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
764      * Absolute scale somewhat unclear so far
765      * no area weighting was included since no other cost term does so far
766    
767    checkpoint57y_post
768    First step for a NLFS adjoint
769    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
770    o new init. routines for calc_r_star, calc_surf_dr
771    o still need to deal with ini_masks_etc
772    o testreport seemed happy
773    checkpoint57y_pre
774    
775    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
776    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
777    o add new offset feature to offline pkg (plus minor cleanup)
778    o cfc fixes for final year of integration
779    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
780      be in GCHEM_OPTIONS).
781    
782    checkpoint57x_post
783    o fix testreport Pb in multiple test experiment.
784    o cleanup our namelist syntax in verification:
785      - make it more F95 standards compliant (some work still needed)
786      - allows the vast majority of our tests to work with gfortran
787    o Non-Hydrostatic:
788     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
789     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
790    o Allow to apply AB on T,S rather than on AB(gT,gS):
791     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
792     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
793       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
794     - need a "clever" read_pickup to restart from the other AB formulation
795    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
796    o remove some unused variables (reduces number of compiler warnings)
797    o adjoint
798      * Disable useVariableViscosity for adjoint for time being
799        (there are a number of extensive recomputations)
800      * Initialize certain variables needed for adjoint
801    
802    checkpoint57w_post
803    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
804                 fix the singleCpuIO RS version of MDSWRITEFIELD
805       and add a WARNING if using globalFiles=T with multi-processors.
806    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
807      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
808    o tracer advection scheme:
809      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
810       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
811       was not very convenient).
812      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
813       (further tests needed for the implicit DST & Flux-Limiter schemes).
814    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
815      and sRef for convenience, handy, when you want to initialize
816      ptracers in a large domain with a constant non-zero value. Also,
817      untangle ptracers_init.F a little.
818    
819    checkpoint57v_post
820    o change dome exp. to use variable viscosity in side-drag terms.
821    o remove all the files from the cfc_offline test since they are now
822      incorporated into tutorial_cfc_offline which has been producing
823      identical results for a few days of testing
824    o add new parameter: sideDragFactor to enable half-slip-side BC
825      and change side-drag S/R to use viscosity from mom_calc_visc
826      (can switch back by setting sideDragFactor=0.); affects results at
827      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
828       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
829    o vorticity & strain are now computed without masking, to account for
830      no-slip-side BC in variable viscosity calculation ; mask is applied
831      anyway later on, before computing advection/coriolis terms.
832    o modify exp4 to test new obcs support for reading from external files
833      and for passive tracers
834    o fix behavior of ptracers_monitor when monitor output is written to a
835      netcdf-file; still not independent of monitor.F (writes in the same
836      file).
837    o change default value of tRef (put a uniform, meaningful value for ocean
838      & atmos) and initialize sRef (was missing, as Martin mentioned).
839    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
840      to be proportional to enstrophy dissipation length.  Thus,
841       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
842      This is now consistent with Smagorinsky and with the manual.
843    
844    checkpoint57u_post
845    o OBCS and PTRACERS: add open boundary support for passive tracers
846      - either use homogenous (pseudo) v.Neumann conditions or prescribe
847        OB-values from file; this is not different from the way theta and salinity
848        are treated
849      - however, Orlanski-radiation conditions are not supported, and the model
850        will stop if you use pTracers and Orlanski at the same time.
851      - beefed up the rountine obcs_external_fields_load: now only those open
852        boundary values are overwritten with values from files for which there
853        are really files, otherwise the OB-fields remain untouched. This makes
854        it possible to use different OBs at different ends of the domain (as
855        with EXF)
856    o reduce number of exch calls in shap_filt (s2).
857    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
858      truncation level) 4/5 MLAdjust test results (11&12 digits match).
859    
860    checkpoint57t_post
861    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
862    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
863      same truncation, independent of the face number: affects affects several
864      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
865    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
866      note that biharmonic viscosity + no-slip was not tested in any experiment.
867    o fix bug in non-linear free-surf side-drag ; generate new output for
868      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
869    o make mnc honor the writeBinaryPrec flag for most kinds of output
870    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
871    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
872      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
873    o add brackets in multi-terms sum to get same truncation, independent of
874      the face number (manage to get exactly same value of gU,gV at the cs-edge)
875      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
876    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
877      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
878      a maximum grid-scale Reynolds number.  Also, changes all length calculations
879      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
880      Suggested values of viscosity parameters found in mom_calc_visc.
881      Many new viscosity diagnostics available.
882    
883    checkpoint57s_post
884    o Add clearing-house for viscosity calculations, mom_calc_visc and
885      correct numerous bugs in LeithD and Smagorinsky discretizations.  
886      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
887      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
888      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
889      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
890      The Strain-Tension form is now called with useStrainTensonVisc=.true.
891      ViscAhStrain and viscAhTension are now retired.
892    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
893    o In response to JMC's bug report, genmake2 now ignores any soft-links
894      that it finds in the *current* directory when searching for files.
895      Soft-links found in any other source directories will still work as
896      they did before.
897    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
898      a C routine to unlimit the stack size
899    o mnc-ify pkg/aim snapshot vars
900    o mnc-ify pkg/land as requested by Daniel
901    o various changes to mnc including:
902      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
903      - output can now be grouped so that all files within a group
904          change the ITER portion of their names in lock-step together
905      - can now read ("global") PER-FACE (in addition to PER-TILE) files
906          and works with both EXCH1 and EXCH2 (but needs more testing)
907      - writing works for all verification test cases w/ g77 on Linux
908    
909    checkpoint57r_post
910    o make MNC variable initialization happen earlier
911    o add diagnostics for (almost) each term of the momentum Eq.
912    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
913    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
914    o remove MINIMAL_TAVE_OUTPUT option ;
915      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
916    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
917      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
918    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
919    o add time-dependent SST, SSS control
920    o cost terms in ecco/ modularized (new cost_generic.F)
921    o cost_averages routines are modularized (new cost_averagesgeneric.F)
922    o new infrastructure for seaice model vs. obs misfits in seaice/
923      * driver from the_main_loop.F is seaice_cost_driver.F
924      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
925      * gradient check in Exp. 6a of natl_box_adjoint/
926    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
927      (see README file)
928    
929    checkpoint57q_post
930    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
931    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
932      - bug was reported by Jean-Michel and Ian Fenty
933    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
934      update exp. cpl_aim+ocn output.
935    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
936      Needed for high-res. runs with large global files
937      to be able to limit tapelev size
938    o Changed some tests for adjoint:
939      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
940      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
941      * global_ocean.90x40x15/ back to default 3-level checkpointing
942    o Modifications to enable scripted COMMON to MODULE conversion
943      * verification/OpenAD/code/ has necessary scripts and description;
944      * converts, compiles and runs successfully;
945    
946    checkpoint57p_post
947    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
948    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
949      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
950    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
951    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
952      (was already the case for dissipation with mom_vecinv,
953       and also the case for grad.PhiHyd when staggered-timeStep)
954      This will allow to put dissipation out-off the AB time-stepping.
955     Unfortunately, affects truncation error. Update output of exp. that "fails"
956      (cg2d matching number) and leave the others for later: front_relax(10),
957      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
958      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
959    
960    checkpoint57o_post
961    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
962      (2) its ready to be documented during the 20050801 DocFest
963    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
964      for ideal_2D_oce and lab_sea on linux_ia32_g77
965    o set to #undef CTRL_SET_OLD_MAXCVARS_30
966      in global1x1_tot/code_seaice_adj to access indices 32, 33
967      (worth another tag)
968    
969    checkpoint57n_post
970    o adding precip control xx_precip 32
971    o adding swflux control xx_swflux 33
972    o Replacing 10 forcing penalty cost routines by 1 generic.
973    o Implementing partitioning in time-mean and variable adjustment
974      for atmos. state.
975    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
976    o in natl_box_adjoint:
977      * updated exp 1 to 10
978        (but does not have time-mean vs. variable split results yet)
979    o updated global1x1/*_seaice_adj/
980      to incorporate latest changes
981    o enable useSingleCpuIO for mdsio vector routines
982      (applies in particular to tapelev I/O)
983    o removed inefficient K-loop in all active_file*control*.F
984    
985    checkpoint57m_post
986    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
987      and advect_cs (use EXCH-2 and standard cs-32 grid files).
988    o pkg/exch2: filling of face-corner halo regions is optional
989      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
990    
991    checkpoint57l_post
992     tag before updating tutorials (pre-release-2)
993    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
994       for output and interpolation of input fields onto model grid)
995    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
996       Affects results of exp. rotating_tank ; update output.txt.
997    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
998          and taking the square quantity and/or using a fraction-weight field.
999    o fix aim_diagnostics_init.F mate numbers.
1000    o add mnc output capability to diagnostics/diagstat and update
1001      our cvsignore files for the ACSII output generated
1002    
1003    checkpoint57k_post
1004    o lab_sea now uses diagnostics package and provides a suite of
1005      new EXF diagnostics output.
1006    
1007    checkpoint57j_post
1008    o exf
1009      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1010        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1011        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1012      * extended diagnostics output
1013        - now includes all EXF variables
1014        - hs, hl moved to common block
1015        - separate S/R for diagnostics, called after ctrl vector is added
1016        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1017        - EXFqnet contains true Qnet (i.e. includes qsw)
1018      * updated verif. lab_sea, global_with_exf
1019      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1020        to ensure that diagnostics sees a true EXFqnet
1021    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1022    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1023      several times with different frequencies.
1024    o mnc-ify the thsice package as requested by Daniel Enderton
1025      - the monitor--MNC output needs work
1026      - many attributes need to be added (most are currently blank)
1027    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1028      - many attributes need to be added (most are currently blank)
1029    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
1030    o add Sadourny like discretization to the 4th.O vorticity advection scheme
1031    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
1032      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
1033         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
1034    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
1035     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
1036    
1037    checkpoint57i_post
1038    o Diagnostics package was changed: diagnostic allocation is now deactivated
1039      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1040    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1041      add 1rst Order upwind vertical Shear.
1042    o add a quick fix for A/B checkpointing in OFFLINE mode
1043    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1044      end-run around the C/Fortran linking horror in eesup/src/timers.F
1045    o added pkg/runclock: allows user to terminate run based on wall clock
1046    o added non-hydrostatic scaling parameter: nh_am2
1047    o pkg/my82: futile attempt to make results compiler-independent by adding
1048      some "_d 0", etc. no effect.
1049    o for mnc output, fill the 'T' coordinate var with myTime and create a
1050      separate 'iter' variable for iteration count
1051    o pkg/diagnostics:
1052      add new capability: output of Global/Regional & per-level statistics ;
1053      tested against monitor output (including land & thSIce) on various exp.
1054    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1055    
1056    checkpoint57h_done
1057      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1058      data.diagnostics, data.gchem, data.ptracers) is done.
1059    
1060    o pkg/diagnostics: prepare for Global/Regional statistics.
1061      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1062    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1063      and rename it: DIFFERENT_MULTIPLE
1064    
1065    checkpoint57h_post
1066    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1067    o pkg/diagnostics: change output frequency, now in seconds (instead
1068      of Nb of iterations). This requires to change data.diagnostics.
1069    checkpoint57h_pre
1070    
1071    o in mnc, let the user create the output dir if both mnc_outdir_date
1072      and mnc_outdir_num are false
1073    o add fflags() to pkg/diagnostics which allows one to specify, on a
1074      per-file basis, the file precision [default behavior is unchanged]
1075    o added diagnostics to pkg/kpp, including computation of mixed layer
1076      depth based on a temperature/density criterion
1077    o updated verification/natl_box to test the new pkg/kpp diagnostics
1078    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1079    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1080    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1081      not mnc -- this mistake was found by JMC and is now corrected
1082    
1083    checkpoint57g_post
1084    o add Adams-Bashforth 3rd Order time stepping:
1085      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1086      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1087    checkpoint57g_pre
1088    
1089    o make lambda[Theta,Salt]ClimRelax spatially varying
1090      (default remains spatially uniform constant based on tau)
1091    o added new control variables
1092      * init. uVel, vVel, etanN
1093      * lambda[Theta,Salt]ClimRelax
1094    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1095      (suggested by G. Forget)
1096    
1097    checkpoint57f_post
1098    o add parameter "baseTime" = model base time = time at iteration zero
1099      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1100      account for baseTime shift
1101    o move Coriolis arrays from PARAMS.h to GRID.h
1102    checkpoint57f_pre
1103    
1104    o mnc-ifying the seaice package
1105    o introduced an alternative length scale calculation for use in the limiting
1106      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1107    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1108    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1109      as well as grad(vort3).  Made it compatible with both approximate form
1110      for the cubed sphere and full form of these gradients.  Added flag
1111      useFullLeith to select between approximate and full form.  
1112    o add "d0" in getcon.F to reduce differences between compilers/platforms
1113      update output.txt of exp. fizhi-gridalt-hs
1114    o change port_rand funtion to allow to set the seed.
1115    o fix obscure MNC bug involving conversion between reals and integers
1116      - it caused no problems with certain (eg. gcc, ifc) compilers but the
1117        new version is now more standards-compliant
1118    o adjoint-related modifications
1119      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
1120      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
1121      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
1122    
1123    checkpoint57e_post
1124    o Adding eddy stress controls a la Ferreira et al.
1125    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
1126    
1127    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
1128      update output.txt of exp. fizhi-gridalt-hs
1129    o add more "Z" dimensions and associated coordinate vars to MNC
1130    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
1131    o parameter calendarDumps: when set, approximate months (30-31 days) and years
1132      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
1133      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
1134      months and years.  Requires pkg/cal.
1135    o diagnostics: add pickup functionality
1136      - off by default for backwards compatibility
1137      - current version only uses MDSIO -- MNC will be added
1138    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
1139    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
1140    
1141    checkpoint57d_post
1142    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1143    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1144      output from the diagnostics package
1145    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1146    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1147      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1148    o add coordinate variables to the MNC output from the diagnostics package
1149    o change MNC-flags default value: true when useMNC=TRUE
1150    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1151      the ability (off by default) to read the grid information using MNC
1152    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1153    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1154    o do snap-shot diagnostics at the middle of the time-interval (instead of
1155      at the end).
1156    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1157      new test for AIM with thSIce + slab-ocean
1158    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1159    o move state variable diagnostics to the beginning of the time step ;
1160      (note: still needs some work specially for snap-shot diagnostics)
1161      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1162    
1163    checkpoint57c_post
1164    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1165    o generate new output.txt files on faulks with g77 & the new -ieee option
1166    checkpoint57c_pre
1167    
1168    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1169      update output.txt of exp. global_ocean.90x40x15
1170    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1171      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1172    o add saltFlux(+File) forcing capability with periodicExternalForcing
1173    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1174    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1175    o improvements for the MNC output from DIAGNOSTICS:
1176      - correct handling of the unlimitied dimension
1177      - all dims now have associated coordinate variables
1178      - variables located at U, V, and Corner ("Z") points are now written
1179        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1180        *all* data points are output
1181    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1182    o added pkg/seaice/seaice_monitor.F
1183    o mdsio_readfield.F can now read files visible only to master MPI process.
1184    o pkg/seaice: some test code for ice-modified ocean stress
1185    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1186      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1187      spurious negative numbers for precipitation and humidity.  Will cause
1188      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1189    o pkg/ctrl/
1190      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1191        May be enabled via doPackDiag
1192      *  introduce z-scaling of
1193         + gradient (doZscalePack) and
1194         + control (doZscaleUnpack)
1195    o pkg/mdsio/
1196      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1197      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1198    
1199    checkpoint57b_post
1200    o simplify options in diagnostics_fill arguments (remove weird combinations)
1201    o fix MNC coordinate variables so that they now contain per-face index
1202      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1203      general, EXCH2 grids are only aligned to a "local" coordinate system
1204    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1205    o Implement instantaneous output within pkg diagnostics:
1206      setting a negative frequency in data.diagnostics produces
1207     "snap-shot" output (as opposed to time-average if freq > 0)
1208    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1209      NOTE: change ptracer diagnostics name: use 2 characters to work with
1210            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1211    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1212      becomes the coordinate variable for the 'T' dimension
1213    o add CF-style coordinate variables to MNC
1214      - just a first cut:  numbers are meaningless on the cubesphere and
1215        missing along the T axis but otherwise it works!
1216    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
1217    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
1218    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
1219      this is based directly on what the model compute, so that the content of
1220      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
1221    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
1222    o clean up build options files for SunOS, in particular
1223      - remove -traditional from xmakedepend
1224      - change -xarch=v9 to -xarch=native for f77
1225      - restore use of make (not gmake)
1226      - add CC=gcc if using g77
1227    o changes per discussion of AM, JMC, & EH3 today:
1228      - move redundant "grid" variables out of "state" -- in preparation of
1229        creating proper CF-style coordinate variables and in recognition
1230        that any/all grid variables can be easily copied (eg. w/NCO) from
1231        the grid files into any of the other NetCDF files
1232      - *always* output grid variables with MDSIO (this will eventually be
1233        changed)
1234      - output MNC grid file if useMNC is true
1235    o every instance of _END_MASTER() has been found and replaced with
1236      _END_MASTER( myThid ) in order to satisfy certain picky Sun
1237      preprocessors
1238    o re-arrange diagnostics pkg initialisation:
1239     - allow each package to extend the available diagnostics list
1240     - add some checking and fix small problems (multi-threaded, ...)
1241     - new S/R diagnostics_fill (replace fill_diagnostics):
1242       look through the short list of active diag. (instead of the long list)
1243       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
1244    
1245    checkpoint57a_post
1246    o this set of changes restores TAMC compatibility
1247      tested for global_ocean.90x40x15 adjoint on trough
1248      (what a pain)
1249    
1250    checkpoint57a_pre
1251    o some modifs in tools/build_options for sunos
1252    o call ctrl_pack for ctrl at end for optimcycle=0
1253    
1254    checkpoint57
1255    o add horizontal bi-harmonic viscosity for vertical velocity
1256      - new parameter viscA4W (defaults to viscA4)
1257      - affects only non-hydrostatic code
1258      - to be done: no-slip lateral boundary conditions
1259    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1260    o implement Implicit Vertical advection for pTracers
1261    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1262      (implemented also for implicit vertical diffusion & advection)
1263    o OBCS: extend application of tracer open boundary conditions
1264      to a strip beyond the boundary of width Olx/Oly
1265    o add call monitor to TAF set of required calls (flow directives)
1266      and include in natl_box_adjoint
1267    o untangle a few ifdefs related to cost, ctrl, autodiff
1268      untangel a few ALLOW_ECCO_OPTIMIZATION
1269    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1270      (theta2, salt2 in ecco_cost_weights)
1271    
1272    checkpoint56c_post
1273    o OBCS as control variables
1274      - update ctrl_ad_diff.list, obcs_ad_diff.list
1275      - remove balance of obcs controls from default
1276      - fix index bug nobcs in ctrl_init
1277      - fix dummy fields filen in ctrl_pack
1278      - add dummy weights for obcs
1279    o lsopt: comment out fort.94 output
1280    o optim:
1281      - remove unnecessary header files
1282      - adjusted namelists
1283      - add xerbla.F to Makefile
1284    o exf:
1285      - multiple modifications of exf_check_range
1286      - unit change in exf_init_runoff from [m/year] to [m/s]
1287    o mdsio:
1288      - i/o-vector change debugLevel from debLevA to debLevB
1289    
1290    checkpoint56b_post
1291    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1292      is called from DO_THE_MODEL_IO
1293      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1294      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1295      - clean up PTRACERS_WRITE_TIMEAVE a little
1296    o add another verification experiment that tests both the cfc-pkg and
1297      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1298      reactive tendencies treated inline with regular timestepping
1299    o testreport previously did a lousy job of comparing small numbers, so
1300      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1301      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1302      testreport.
1303    o ptracers_monitor: bug fix for MPI
1304    
1305    checkpoint56a_post
1306    o GCHEM: finish reorganizating the package
1307      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1308        (introduces another 3D-array for each passive tracer, but only if
1309        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1310        gchemTendency is not needed because the timestep is done separately)
1311      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1312      - GCHEM is now---more or less cleanly---separate from PTRACERS
1313      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1314        so clear to me how that should be done in a general way.
1315    o CFC: improve formatting of output in CFC_ATMOS
1316    o PTRACERS:
1317      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1318        that ALL experiments with ptracers enable can be checked. This makes
1319        GCHEM_MONITOR obsolete.
1320      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1321        monitorFreq
1322      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1323    o add PTRACERS (PTR0[1-5]) to testreport output
1324    o exf_check_range:
1325      * default changed to .TRUE.
1326      * will check values for niter0 if debLevA, every timestep if debLevB
1327      * STOP in exf_check_range if 'out of range'
1328      * range chosen generous to allow for potential extema
1329      TBD: a version with stricter range
1330           permitted range would be runtime parameters
1331  o GMredi:  o GMredi:
1332    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1333    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
# Line 11  o GCHEM: Line 1336  o GCHEM:

1338    - introduced a useGCHEM runtime flag and applied it everywhere.    - introduced a useGCHEM runtime flag and applied it everywhere.
1339      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1340        this flag is now only visible within GCHEM-pkg routines.
1341      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1342        be replaced by a 3D array that is computed before thermodynamics; for
1343        this, the tracer ID iTracer had to be included into the parameter list
1344        of ptracers_forcing
1345      - set up forward_step to call gchem_forcing, that will replace
1346        gchem_forcing_int in ptracers_forcing
1347      - cleaning up
