5      ==============================      ==============================
6    
7    o pkg/exf:
8      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
9      EXF_INTERPOLATION:
10      - merge global_with_exf/code version of exf_interp_read.F
11        to the main code ;
12      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
13        reading the file ; Important: This options needs to be defined to recover
14        previous code.
15        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
16      - no longer loose real*8 precision along the way when using exf_iprec=64.
17    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
18      - change discretisation of evp-solver in order to avoid another exchange
19        (changes lab_sea) and clean up a little
20      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
21        help the adjoint (this also changes the results slightly)
22      - add a few "_d 0" where they had been missing in seaice_evp.F
23      - cleaning up: remove unused seaice_calc_rhs.F
24    o pkg/exf: some cleaning-up:
25      - change various "constants" into runtime parameters
26      - cleaned-up Large&Yeager04 routine which should eventually
27        replace exf_bulkformulae.F (changed names of S/R and CPP)
28        and merged various ALLOW_ATM_WIND options
29     only used with thsice pkg (in thsice_get_exf.F):
30      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
31        which are used when useStabilityFct_overIce=TRUE (= the default)
32      - change default values of ice & snow emissivity and scale downward LW
33        by ice & snow emissivity.
34    o pkg/thsice:
35     fix few little problems, in thsice_calc_thickn.F:
36      - growth vertically (and not laterally) if iceFrac == iceMaskMax
37      - melt laterally only if hIce < hThinIce (as the comments say)
38      and in thsice_extend.F:
39      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
40      - start to form ice as soon as the minimum ice-volume is reachable.
41     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
42      and cpl_aim+ocn
43    o pkg/kpp
44     - move computation of surface related input fields to KPP into a new
45       subroutine kpp_forcing_surf.F
46     - remove wrong (within bi,bj loops) EXCH calls.
47     - little cleaning (add argument myThid in last position, cvs header ...)
48     - for now, fix conservation problem by exchanging KPPviscAz (may not
49       be the best fix)
50    o pkg/seaice
51     - check for inconsistent evp parameter/cpp-flag combination
52     - remove leftover errIO flat for obsolete name list error handling
53    o OpenAD
54     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
55    
56    checkpoint59a
57    o pkg/seaice: some parameter clarifications and a little bit of clean up
58    o pkg/thsice: rename run-time parameters:
59       himin       -> hIceMin
60       himin0      -> hThinIce
61       hihig       -> hThickIce
62       i0          -> i0swFrac
63       transCoef   -> bMeltCoef
64       frac_energy -> fracMelting
65      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
66       with default values (for now) that do not change the results.
67      remove old version of thsice vars advection in pkg/seaice.
68    o in FFIELDS.h:
69      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
70      - make pLoad & sIceLoad always available (but still only used if
71         ATMOSPHERIC_LOADING is #define).
72    o pkg/kpp: replaced _KPP_RL with _RL
73    o bug fixes for vertical diffusivity computations when both KPP and
74        3D diffusivity arrays are used.
75    o pkg/seaice: fix bug in evp solver, while doing that
76      - change (improve?) discretization of stress computations for both
77        cgrid-lsr and evp solver
78      - add a new routine to compute strain rates
79      - the above changes lab_sea results
80      - add no slip conditions for evp solver (off by default), lsr-version
81        may follow
82      - fix exchange for shear at Z-points (does not change lab_sea)
83      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
84        (to force the user to pick a time step since there is not "safe" way
85        of choosing it)
86      - add principal stress diagnostics
87      - rearrange fields for evp a little to avoid having to call a: too many
88        exchanges and b: exchanges for stress trensor components which we do
89        not have.
90      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
91        of evp, complete rewrite for lsr case (latter is does not yet work
92        in all cases)
93    o pkg/kpp: add code to have mixing in shelf ice caverns
94      - add myThid to all kpp routines (long overdue)
95    
96    checkpoint59
97    o pkg/exf:
98      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
99        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
100      - move exf header files from lower_case.h to UPPER_CASE.h ;
101        add missing cvs Header & Name
102      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
103      - add namelist param. selectStressGridPosition, exf_monFreq
104      - retire many _CLIM routines, and remove data.exf_clim
105        + params moved to data.exf
106        + climsst, climsss now handled by exf_set_gen, i.e.
107          climss?period=0 refers to constant field,
108          climss?period=-12 to monthly forcing
109      - split up namelists in data.exf
110    o pkg/seaice:
111      - remove seaice_exch and seaice_exch_uv
112      - remove superfluous exchange of theta
113      - add myThid to seaice_budget_ocean/ice
114      - add new interface for atmospheric wind forcing (C-grid only)
115        + new routine
116        + two new field (taux, tauy for stress over ice)
117        + removed one global field (DAIRN) for C-grid case only
118    o pkg/thsise
119      - 2nd set of modifs for thsice adjoint in conjunction with exf
120    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
121    
122    checkpoint58y_post
123    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
124      vertical diffusivity, similar to that in MOM4; turned on using
125      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
126      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
127    o Added capability for 3D specification of background vertical diffusion
128      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
129      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
130      "data" file that contains the 3D vertical diffusivity coefficients.
131    o ice dynamics (pkg/seaice) with thsice thermodynamics:
132      - add code within pkg thsice to advect & diffuse sea-ice fields
133      similar to (and will replace) what has been added in  seaice_advdiff.F,
134      but: - conserving Mass, Heat & Salt.
135           - better when using non-linear advection scheme (not yet fully tested)
136           - can also be used in atmospheric set-up (for now, only the diffusion).
137    
138    checkpoint58x_post
139    o IO option for global-file compact format:
140      - add options when generating topology (utils/exch2/matlab-topology-generator)
141      - add I/O capability (pkg/mdsio).
142      - adapt utils/matlab/rdmds.m to read this format.
143      for now long-line format not yet supported by pkg/mdsio (& exch2).
144    o shelfice: add a few diagnostics
145    
146    checkpoint58w_post
147    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
148      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
149      (and replace horiVertRatio in NH code).
150      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
151                         and tutorial_plume_on_slope (sensitive to truncation)
152    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
153      directly to drive seaice model (C-grid only)
154    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
155     - reintroduce computation of wind from stress,
156     - compute tau (in exf_bulkformulae.F) from windstress averaged to
157       mass points to avoid tau = 0
158     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
159    o rdmnc.m: make it work with "global" files created with gluemnc
160    o rdmnc.m : some improvements in dealing with singleton dimension
161      (tested on all testreport mnc output files).
162    o genmake2: disable pkg/profiles if netcdf test fails.
163    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
164    o move call to cal_readparms up to make calendar parameters/variable available
165      to all packages
166    
167    checkpoint58v_post
168    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
169      useDynP_inEos_Zc tested.
170    o pkg/exf: changes to properly interpolate/mask/scale initial fields
171    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
172      and portions thereof.  See read_cs.txt for description and examples.
173    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
174      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
175      following the great-circle arc between those 2 points.
176    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
177      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
178    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
179     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
180     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
181     - still needs work (not working with some options ; efficiency to improve)
182       and serious testing.
183     - use this scheme for temperature & salinity in 2 advection test exp.:
184       advect_xy & advect_xz, respectively.
185    
186    checkpoint58u_post
187    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
188    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
189    o testreport: add option "-skipdir" to skip some test.
190    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
191      momentum calculation.
192    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
193    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
194      remove checkpoint.F and the_correction_step.F (no longer used);
195      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
196    o add option (linFSConserveTr) to correct for tracer source/sink due to
197      Linear Free surface
198    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
199    o pkg/thsice: fix reading mnc-pickups
200    
201    checkpoint58t_post
202    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
203    o pkg/mdsio:
204     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
205       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
206       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
207     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
208     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
209       either MDS_READ_FIELD or MDS_WRITE_FIELD )
210     - new S/R (to replace MDSWRITEMETA), which allows to write more
211       informations (variable names, time ...) to meta files.
212     - modify rdmds.m to give back the meta file content.
213    o pkg/diagnostics: change vertical interpolation to be safer, and more
214       flexible (define p-levels to interpolate to in data.diagnostics);
215      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
216       diagnostic pointer.
217    o pkg/seaice: more cleaning up of seaice_growth, added many comments
218    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
219    o fix multi-category seaice:
220     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
221       SEAICE_MULTICATEGORY
222     - fix short wave heat flux
223    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
224       and allow to use EVP solver. Change forward lab_sea: test both EVP
225       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
226    o Initial check-in of lab_sea adjoint
227      (very similar to natl_box_adjoint/code_seaice)
228      * used C-grid and EVP solver
229      * used KPP, GM/Redi
230      * uses inAdExact=.TRUE.
231      * gradient checks fail for both ADM and TLM
232        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
233        f.d. gradients actually seem more problematic than ADM, TLM gradients;
234        issue is related to forward mismatch between g77 an ifort
235    o pkg/seaice: overhaul of thermodynamics
236     - growth.F and groatb.F are replaced by new routine seaice_growth.F
237     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
238     - move a few global fields out of SEAICE.h into seaice_growth.F and
239       make them 2D (FICE/QNETO/ ...)
240     - remove FO (it is the same as QNETO)
241     - introduce a few local fields to avoid modifying external fields such
242       as atemp, etc.
243    
244    checkpoint58s_post
245    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
246      changed exf_set_gen.F so that
247        genperiod=0 means input file is one time-constant field and
248        genperiod=-12 means input file contains 12 monthly means
249    o CG2D: use pre-computed solver main-diagonal (stored in common block);
250      this affects truncation error ; generate new output file for exp. which
251      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
252        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
253        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
254        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
255        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
256        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
257    o start implementation of deep-atmosphere and anelastic formulation
258    o verification: remove 2nd copy of input files and use script "prepare_run"
259      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
260    o mom_common/vecinv/fluxform: fix a few initialisation isssues
261    o profiles: fix for multithreaded case
262    
263    o diagnostics: rename few diags:
264      s/'PRESSURE'/'RCENTER '/g
265      s/'TICE    '/'oceFreez'/g
266      s/'TAUX    '/'oceTAUX '/g
267      s/'TAUY    '/'oceTAUY '/g
268      s/'SWFLUX  '/'oceQsw  '/g
269      s/DIFx/DFxE/g
270      s/DIFy/DFyE/g
271      and add few ocean-forcing diagnostics:
272      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
273    o modifications to pkg/seaice/growth.F and budget.F, which change results of
274      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
275      as actual snow thickness.  It now refers everywhere to effective snow
276      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
277    
278    checkpoint58r_post
279    o modifications to pkg/seaice/growth.F, which change results of
280      lab_sea experiment: fixes pertain to melting snow over open water, to
281      masking EVAP under sea ice, and to using the correct AREA variable for
282      computations of EVAP, PRECIP, HSNOW, and GHEFF
283    o add ability to read bathy, salt, and theta using MNC (off by def)
284    o add flooding algorithm and advection of HSNOW for pkg/seaice;
285      both are turned off by default and do no change any results
286    o seaice advection with pkg/thsice: a step toward the use of non-linear
287      advection scheme, but #ifdef or commented out for now (requires more EXCH).
288    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
289      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
290      in natl_box (affects results @ truncation level: update output.txt)
291    o multi-threading and IO:
292      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
293      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
294        (needed to work with SingleCpuIO): tested in all verif. exp.
295    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
296      affects the results (but none of the verification test uses this scheme).
297    o Adding some pkg/diagnostics capability to pkg/seaice
298      (will certainly be subject to changes)
299    o ctrl: adding new control variables:
300      lwflux, lwdown, evap, snowprecip, apressure, runoff
301    
302    checkpoint58q_post
303    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
304      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
305      high_res_cube configuration by 4% on Columbia.
306    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
307      add (in global_with_exf/code) a version of EXF_INTERP_READ without
308      dynamical allocation (seems to work in multi-threaded).
309    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
310      single CPU io) so that TAF does not have to see EESUPPORT.h
311    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
312    
313    checkpoint58p_post
314    o obcs: stop if obcs is used with useCDscheme = .true.
315    o shelfice:
316     - fix a sign error so that no slip at shelfice interface works
317     - remove stop for combination non-hydrostatic code and shelfice. That does
318       not mean, that the results are correct, but at least they are numerically
319       stable
320    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
321    o added adjoint exch routined for all exch*3d* routines
322      and updated flow directives
323    
324    checkpoint58o_post
325    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
326      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
327    o change controling S/R for writing pickup file (new S/R do_write_pickup)
328      and clean-up reading/writing of pickup files.
329    o fix local version of read/write pickup (NH part) in rotating_tank/code
330    o simplify EXCH interface:
331     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
332     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
333    o added the regrid package
334    o shelfice:
335     - add a simple boundary layer scheme to reduce noise
336     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
337    
338    checkpoint58n_post
339    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
340       local variable (not in common block).
341    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
342      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
343      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
344        to work with SingleCpuIO.
345    o add "_d 0" to real constant of pkg/cfc subroutines ;
346       update exp. cfc_exemple & tutorial_cfc_offline output files.
347    o multi-threading and IO:
348      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
349        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
350      - barrier before and after reading.
351      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
352      - avoid using MDS_WRITELOCAL for LAND pkg output.
353      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
354        common-block variables ; Allows multi-threading with master-thread IO.
355    o change default MAX_NO_THREADS from 32 to 4 ;
356      and stop cleanly when MAX_NO_THREADS is too small.
357    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
358    
359    checkpoint58m_post
360    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
361       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
362    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
363       keep global_ocean.90x40x15 (for AD testing) with former secondary test
364       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
365    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
366        add MITgcm_tutorials (= code + all the tutorials)
367    o ecco, option to compute cost for total ssh (mean+anom)
368    o consistent with addition of ptracer and ssh in pkg/profiles
369    o profiles: adding ptracer and ssh
370    o testreport: change multi-test output-file name
371      (from output.txt.{name} to output.{name}.txt)
372    o profiles: now ok for mutli-tiles case
373    o seaice: add 4 parameters for different advection schemes for area,
374      (effective) seaice thickness, enthalphy, and snow height. Their default
375      is the standard parameter SEAICEadvScheme
376    o calc_gw:
377     - add cosFacU in zonal viscous flux (harmonic.visc.).
378     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
379       of tutorial_plume_on_slope.
380    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
381    o calc_gw: true flux-form, account for horizontal grid spacing.
382      update rotating_tank results, but not plume_on_slope (affected at
383      truncation level, 11 digits).
384    
385    checkpoint58l_post
386    o calc_gw:
387     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
388     - remove side-drag for now (need to fix it); update plume_on_slope results.
389     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
390    o commit code to make SST/SSS weights spatially variable
391      (based on either variable in-situ or variable initial T/S weights)
392    o pkg/ecco:
393      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
394        now based on horizontally varying weights wthetaLev, wsaltLev
395      * cost_averagesflags now returns year indices in addition to day, month
396      * sflux balance is performed on annual basis
397        (sflxumm, sfluxmm2, bal_sfluxmm)
398      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
399        including separate counting and multipliers
400    o pkg/rbcs
401      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
402    
403    checkpoint58k_post
404    o testreport:
405     - always build in dir. "build" (if not there, mkdir build instead of building
406       & running in input)
407     - run in dir run (if it exists), in build otherwise.
408     - call prepare_run (if input/prepare_run exists)
409     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
410    o pkg/exf modifications to interpolation and rotation routines for more
411       reasonable treatment of North Pole singularity: for tracers North Pole
412       value is set to northernmost zonal-mean value, for zonal velocity it is
413       set to zero, and for meridional velocity it is set to northernmost value.
414    o pkg/exf/exf_check_range.F
415     - add tile index to diagnostics and move stop statement to the very
416       end of the routine.
417    o pkg/diagnostics: (diagnostics_main_init.F)
418      define title of isomorphic variables according to the current config.
419    o pkg/thsice with pkg/seaice dynamics:
420    - fix domain of computation (interior only, required for exf) and do exchanges
421    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
422    o towards a standard way of dealing with multi-threading in MONITOR
423      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
424    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
425       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
426    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
427    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
428    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
429       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
430    o tracer advection:
431     - clean-up and simplify calc_common_factors.F
432     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
433       advection subroutine (but still not used within DST advection S/R)
434    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
435    
436    checkpoint58j_post
437    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
438      from file (collects calls previously in FORWARD_STEP)
439    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
440    o adjoint store dir. adjusted accordingly
441    o genmake2
442      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
443    
444    checkpoint58i_post
445    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
446      on wind stress (SEAICEstressFactor defaults to 1.)
447    o Total number of Timers is finite (<=40): comment out 2 non-essential one
448      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
449    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
450      on CS-grid: no longer loosing mass.
451    o exf & curvilinear-grid: no longer modify longitude xC & xG.
452    o pkg/ggl90: fix sloppy output and fix a bug
453    o pkg/seaice: added SEAICEuseEVPpickup parameter
454      - Set to false in order to start EVP solver with
455        non-EVP pickup files when using SEAICEuseEVP
456      - fix sign error in diffusion in seaice_calc_rhs
457    
458    checkpoint58h_post
459    * Modifications for bottom topography control
460      o replace hFacC by _hFacC at various places
461      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
462      o add non-self-adjoint cg2d_nsa
463      o update autodiff support routines
464      o re-initialise hfac after ctrl_depth_ini
465      o works for 5x5 box, doesnt work for global_ocean.90x40x15
466    * Adding verification for 5x5 box (4-layer) bottom topography control
467    
468    checkpoint58g_post
469    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
470       used for mean seasonal cycle, mean diurnal cycle); add an example
471       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
472    o pkg/ggl90:
473      - add parameter (minimum surface kinetic energy)
474      - fix bug (avoiding division by zero)
475    o couple pkg/thsice to pkg/seaice:
476      - modify advection in seaice to accomodate new scalar fields to be advected
477      - only muliDimAdection scheme work with seaice/thsice
478      - mapping of thsice-variables to seaice-variables, back and forth
479      - does not break the verification experiments, but does not give the
480        desired results either
481    o pkg/seaice
482      - make (default) second order advection a bit less confusing?
483    
484    checkpoint58f_post
485    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
486      to pkg/seaice):
487      - new routines thsice_map_exf and thsice_get_exf provide the interface
488      - add an additional formal parameter to thsice_solve4temp
489    o pkg/exf:
490      - add new fields wspeed, snowprecip (to be able to couple to thsice)
491      - correct Stefan-Boltzmann constant
492      - new parameter for longwave surface emittance
493      - separate some stuff from exf_bulkformulae into new routines  
494        exf_radiation, exf_wind
495      - add new parameters and constants: longwave emissivity for ocean, ice
496        and snow, evaporation parameters over ice
497      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
498        either wind from stress or stress from wind
499    o pkg/thSIce:
500    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
501    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
502       and THSICE_CALC_THICKN
503    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
504    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
505      to make debugging easier.
506    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
507    o pkg/bulk_force:
508      - clean-up comments and parameters ;
509      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
510    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
511      generate new output for test-experiment: aim.5l_cs.thSI
512    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
513      testreport accordingly
514    
515    checkpoint58e_post
516    o SEAICE_CGRID adjoint done
517    o R_STAR adjoint implemented.
518      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
519      * need to sort out init. of h0facc, etc.
520    o Make pkg/profile fully independent of ecco,cost, etc. stuff
521      to be able to use it in pure forward.
522    
523    checkpoint58d_post
524    o upgrade simple test-experiment to tutorial example:
525     step.1: duplicate the experiment and (step.2) will remove the old copy.
526      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
527      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
528      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
529      tutorial_global_oce_biogeo    <- copy of dic_example
530      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
531      tutorial_plume_on_slope       <- copy of plume_on_slope
532      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
533      tutorial_global_oce_optim     <- empty for now (David ?)
534      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
535     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
536    o correct a sign problem in cost_scat.F
537    o obcs and ptracers: fix boundary conditions for advections schemes
538      with larger stencil
539    o thsice adjoint: start
540    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
541      completeness
542    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
543      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
544    o ptracers adjoint:
545      * avoid extensive recomputatations
546      * fix missing re-init. of gptr (missed by TAF)
547    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
548      me to turn off the excessive output to STDOUT that this package produces
549    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
550      and add those terms in Vector-Invariant formulation.
551    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
552      if the control period (xx_hfluxperiod etc) is 0
553    o in profiles pkg, clean routines and fix details
554    o in ecco pkg, reading ssh data:
555      fix problem in case the model does not start at iter0=0
556    o fix mnc-pickup/restart for ptracers
557    o new package prifiles:
558      code to compute profile-based cost by Gael Forget
559      (modifs in ecco, ctrl, autodiff)
560    o Benign bug fix in initialization (spotted by M. Mazloff) of
561      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
562    
563    checkpoint58c_post
564    o adjoint: finish NLFS adjoint and provide reference output in
565      verification/global_ocean.90x40x15/results_ad_nlfs
566    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
567      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
568      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
569      with SEAICE_CGRID defined.
570    o move calendarDumps from "data" to "data.cal" and clean-up the code
571      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
572    o add useEXF & useCAL flags (for now, set in hard-coded way)
573    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
574      (were missing in NH mode, and wrong in quasihydrostatic mode).
575      waiting for Chris updated version of calc_gw to add those CALLs.
576    o fix bug in quasihydrostatic S/R ;
577      add a test for this option: global_ocean.90x40x15.qshyd
578    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
579      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
580    o add on/off flag useOffLine for package OFFLINE
581    o seaice:
582      - modify advection so that it works also on the C-grid
583      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
584        problem in multi-tile runs with C-grid
585      - add flags for clipping ice velocities and/or masking solver forcing
586      - fix drag (ocean on ice) formulation and a bug that caused noise in the
587        C-grid solver
588      - added a few comments to seaice_diffusion.F
589      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
590        are now exclusive)
591      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
592        required re-ordering the code a little:
593       + make DAIRN global variable (defined in SEAICE)
594       + move computation of the viscosities eta and zeta into a new separate
595         routine (because I need to recompute them in seaice_ocean_stress.F)
596    
597    checkpoint58b_post
598    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
599      update output.txt of exp. aim.5l_cs.thSI
600    o various mnc cleanups and improvements:
601      + shrink lookup tables by factor of ~4
602      + better error reporting when running out of lookup space
603      + able to handle longer path/file names (up to 500 chars)
604    o adjoint:
605      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
606      - TBD: "hidden" mom_vecinv recomp. in dynamics
607    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
608     (allow to differentiate between forcing components using new integer flags:
609      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
610     and add new flag to put Dissipation tendency out of Adams-Bashforth.
611    o ecco
612      - enable trend removal from SSH anomaly obs.
613    o adjoint
614      - a fix for PmEpR when #undef EXACT_CONSERV
615      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
616      - try to fix "hidden" recomp. in forward_step for NLFS
617        (NLFS seems broken sometimes after I checked it in)
618    o seaice:
619     - add c-grid version of the dynamic solver:
620       + three new routines that are the c-grid substitute lsr, dynsolver
621         and ostres
622       + put a few fields that were local to dynsolver into global common
623         blocks, so that I can move the computation of stresses etc into
624         seaice_lsr (saves coding but may break the adjoint).
625     - replace more hardwired parameters by runtime parameters
626     - add ice masks that mask the rhs of the implicit solvers where there
627       is no ice (commented out in seaice_dynsolver, because i am not sure
628       if this works properly), eventually this should replace the clipping
629       of ice velocities in seaice_dynsolver to +/-40cm/s.
630    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
631      include it only where its needed
632    o move balancing of fluxes before the call of external_forcing_surf
633    o seaice:
634      - correct units of turning angles (now they are really in degrees)
635      - move computation of GWATX/Y out of main routine into dynsolver
636      - initialize GWATX/Y in seaice_init
637    o Apply mask on Fresh-Water flux (needed for SSH forcing).
638      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
639    o seaice: add runtime flags for turning angles (default to zero)
640    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
641      and trend from exf forcing and ctrl control adjustments
642    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
643      (since checkpoint57x_post)
644    o change the default rotation period to 86164.s = the Earth rotation
645    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
646      and based on a reference stratification. Tested within hs94.cs-32x32x5.
647    o seaice advection: add code for choosing between the default (2nd order
648      central differences) and multiDim advection schemes provided by
649      pkg/generic_advdiff
650    o seaice:
651      - removed all references to SEAICE_GRID.h fields from
652        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
653        (cubed-sphere configuration will change a little)
654      - grid computations in seaice_init are obsolete now.
655      - cleaned up code a little so that is easier to read (hopefully).
656      - added new (better?) discretizations of default advection and diffusion
657        (turn on with SEAICEuseFluxForm)
658      - replace 1 in 3d global fields by kSurface in growth.F
659      
660    checkpoint58a_post
661    o seaice:
662      - bug fix in advect.F
663    o shelfice:
664      - separate shelfice load anomaly from pload (breaks with time
665        dependent forcing), => introduce constant field shelficeLoadAnomaly.
666        Its default is 0., but it may be computed more cleverly from (unknown)
667        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
668        done offline. A good approximation of the pressure load anomaly is
669        necessary to avoid large initial adjustment processes underneath
670        deep-reaching shelfice.
671      - small fix in ISOMIP shelfice_thermodynamics
672      - add more sophisticated thermodynamics of Hellmer (1989), this is
673        now the default
674      - give a few constants more intuitive names
675    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
676      if bulk formulae are used in long integration (especially EmPmR). Turn
677      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
678      if balancePrintMean, the imbalance that is substracted is printed to
679      STDOUT.
680    o fix bug (typo) in obcs_apply_eta.F
681    o add a new package shelfice which enables us to model the circulation
682      underneath shelf-ice with draughts of hundreds of meters.
683     - works
684     - to do: + include improved thermodynamics
685              + check whether kSurfC (from model/inc/SURFACE.h) can be used
686                instead of new field kTopC
687              + can we use topoFile, Ro_surf and existing code in ini_depth.F
688                instead of new field R_shelfIce and new code in ini_depth.F
689                and ini_mask_etc.F?
690              + adjust vertical mixing schemes?
691    o seaice pkg:
692     - add a cpp-flag to include a simple formula for a salinity dependent
693       freezing point of sea water at the surface
694     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
695       meridional stresses are now different (and hopefully correct)
696    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
697       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
698       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
699    o pkg/diagnostics: add options and parameters for regional-statistics
700       diagnostics ; define regions by reading a region-mask from a file
701       (might add other options later)
702    o pkg/bulk_force:
703     - add option and parameters to use AIM surface-flux formulae.
704     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
705       others forcing fields (defined in PARM05, parameter file "data") are loaded
706       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
707     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
708     - use the right EXCH call for uwind,vwind (to work on CS-grid).
709     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
710       and parameters (note: calcWindStress replaces .NOT.readwindstress).
711     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
712    
713    checkpoint58
714    o add "--embed-source" option to genmake2 which, when the supporting
715      tools can be compiled (as determined by genmake2) will turn on the
716      embed_files package which then embeds the entire MITgcm source code
717      (*.[fFhc] + Makefile) used for the build within the executable
718      - requested by CNH but off by default
719      - adds a paltry <9MB to the mitgcmuv executable in most cases
720      - only writes the output when useEMBEDSRC in eedata is true
721    o clean up 3-dim. relaxation codes:
722      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
723      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
724      * Thanks to Tom Haine for testing!
725    
726    checkpoint57z_post
727    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
728      affects output (@ truncation level) of exp. plume_on_slope ; updated.
729    o fix the pickup behavior for obcs in combination with ptracers
730    o fix a bug in ptracers_external_fields_load
731    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
732      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
733    o transfered surface NH pressure to eta field (if exactConserv).
734    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
735         and update lab_sea output.txt file.
736    o completing 3-dim. relaxation code: additional term
737         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
738      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
739      * At compile time, in "EXF_OPTIONS.h" set
740          #define  ALLOW_CLIMTEMP_RELAXATION
741          #define  ALLOW_CLIMSALT_RELAXATION
742      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
743          tauThetaClimRelax3Dim = 15552000.0,
744          tauSaltClimRelax3Dim  = 15552000.0,
745      * 3 cases:
746          1) Use a constant-in-time 3-dim. field
747          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
748          3) Real-time relax. to time-evolving prescribed field
749    o Adding Laplacian-type smoothness constraint on
750      initial and boundary (forcing) controls (ic, bc)
751      * enable at compile-time via
752        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
753      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
754      * Absolute scale somewhat unclear so far
755      * no area weighting was included since no other cost term does so far
756    
757    checkpoint57y_post
758    First step for a NLFS adjoint
759    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
760    o new init. routines for calc_r_star, calc_surf_dr
761    o still need to deal with ini_masks_etc
762    o testreport seemed happy
763    checkpoint57y_pre
764    
765    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
766    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
767    o add new offset feature to offline pkg (plus minor cleanup)
768    o cfc fixes for final year of integration
769    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
770      be in GCHEM_OPTIONS).
771    
772    checkpoint57x_post
773    o fix testreport Pb in multiple test experiment.
774    o cleanup our namelist syntax in verification:
775      - make it more F95 standards compliant (some work still needed)
776      - allows the vast majority of our tests to work with gfortran
777    o Non-Hydrostatic:
778     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
779     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
780    o Allow to apply AB on T,S rather than on AB(gT,gS):
781     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
782     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
783       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
784     - need a "clever" read_pickup to restart from the other AB formulation
785    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
786    o remove some unused variables (reduces number of compiler warnings)
787    o adjoint
788      * Disable useVariableViscosity for adjoint for time being
789        (there are a number of extensive recomputations)
790      * Initialize certain variables needed for adjoint
791    
792    checkpoint57w_post
793    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
794                 fix the singleCpuIO RS version of MDSWRITEFIELD
795       and add a WARNING if using globalFiles=T with multi-processors.
796    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
797      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
798    o tracer advection scheme:
799      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
800       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
801       was not very convenient).
802      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
803       (further tests needed for the implicit DST & Flux-Limiter schemes).
804    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
805      and sRef for convenience, handy, when you want to initialize
806      ptracers in a large domain with a constant non-zero value. Also,
807      untangle ptracers_init.F a little.
808    
809    checkpoint57v_post
810    o change dome exp. to use variable viscosity in side-drag terms.
811    o remove all the files from the cfc_offline test since they are now
812      incorporated into tutorial_cfc_offline which has been producing
813      identical results for a few days of testing
814    o add new parameter: sideDragFactor to enable half-slip-side BC
815      and change side-drag S/R to use viscosity from mom_calc_visc
816      (can switch back by setting sideDragFactor=0.); affects results at
817      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
818       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
819    o vorticity & strain are now computed without masking, to account for
820      no-slip-side BC in variable viscosity calculation ; mask is applied
821      anyway later on, before computing advection/coriolis terms.
822    o modify exp4 to test new obcs support for reading from external files
823      and for passive tracers
824    o fix behavior of ptracers_monitor when monitor output is written to a
825      netcdf-file; still not independent of monitor.F (writes in the same
826      file).
827    o change default value of tRef (put a uniform, meaningful value for ocean
828      & atmos) and initialize sRef (was missing, as Martin mentioned).
829    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
830      to be proportional to enstrophy dissipation length.  Thus,
831       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
832      This is now consistent with Smagorinsky and with the manual.
833    
834    checkpoint57u_post
835    o OBCS and PTRACERS: add open boundary support for passive tracers
836      - either use homogenous (pseudo) v.Neumann conditions or prescribe
837        OB-values from file; this is not different from the way theta and salinity
838        are treated
839      - however, Orlanski-radiation conditions are not supported, and the model
840        will stop if you use pTracers and Orlanski at the same time.
841      - beefed up the rountine obcs_external_fields_load: now only those open
842        boundary values are overwritten with values from files for which there
843        are really files, otherwise the OB-fields remain untouched. This makes
844        it possible to use different OBs at different ends of the domain (as
845        with EXF)
846    o reduce number of exch calls in shap_filt (s2).
847    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
848      truncation level) 4/5 MLAdjust test results (11&12 digits match).
849    
850    checkpoint57t_post
851    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
852    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
853      same truncation, independent of the face number: affects affects several
854      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
855    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
856      note that biharmonic viscosity + no-slip was not tested in any experiment.
857    o fix bug in non-linear free-surf side-drag ; generate new output for
858      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
859    o make mnc honor the writeBinaryPrec flag for most kinds of output
860    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
861    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
862      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
863    o add brackets in multi-terms sum to get same truncation, independent of
864      the face number (manage to get exactly same value of gU,gV at the cs-edge)
865      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
866    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
867      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
868      a maximum grid-scale Reynolds number.  Also, changes all length calculations
869      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
870      Suggested values of viscosity parameters found in mom_calc_visc.
871      Many new viscosity diagnostics available.
872    
873    checkpoint57s_post
874    o Add clearing-house for viscosity calculations, mom_calc_visc and
875      correct numerous bugs in LeithD and Smagorinsky discretizations.  
876      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
877      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
878      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
879      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
880      The Strain-Tension form is now called with useStrainTensonVisc=.true.
881      ViscAhStrain and viscAhTension are now retired.
882    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
883    o In response to JMC's bug report, genmake2 now ignores any soft-links
884      that it finds in the *current* directory when searching for files.
885      Soft-links found in any other source directories will still work as
886      they did before.
887    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
888      a C routine to unlimit the stack size
889    o mnc-ify pkg/aim snapshot vars
890    o mnc-ify pkg/land as requested by Daniel
891    o various changes to mnc including:
892      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
893      - output can now be grouped so that all files within a group
894          change the ITER portion of their names in lock-step together
895      - can now read ("global") PER-FACE (in addition to PER-TILE) files
896          and works with both EXCH1 and EXCH2 (but needs more testing)
897      - writing works for all verification test cases w/ g77 on Linux
898    
899    checkpoint57r_post
900    o make MNC variable initialization happen earlier
901    o add diagnostics for (almost) each term of the momentum Eq.
902    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
903    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
904    o remove MINIMAL_TAVE_OUTPUT option ;
905      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
906    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
907      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
908    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
909    o add time-dependent SST, SSS control
910    o cost terms in ecco/ modularized (new cost_generic.F)
911    o cost_averages routines are modularized (new cost_averagesgeneric.F)
912    o new infrastructure for seaice model vs. obs misfits in seaice/
913      * driver from the_main_loop.F is seaice_cost_driver.F
914      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
915      * gradient check in Exp. 6a of natl_box_adjoint/
916    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
917      (see README file)
918    
919    checkpoint57q_post
920    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
921    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
922      - bug was reported by Jean-Michel and Ian Fenty
923    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
924      update exp. cpl_aim+ocn output.
925    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
926      Needed for high-res. runs with large global files
927      to be able to limit tapelev size
928    o Changed some tests for adjoint:
929      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
930      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
931      * global_ocean.90x40x15/ back to default 3-level checkpointing
932    o Modifications to enable scripted COMMON to MODULE conversion
933      * verification/OpenAD/code/ has necessary scripts and description;
934      * converts, compiles and runs successfully;
935    
936    checkpoint57p_post
937    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
938    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
939      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
940    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
941    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
942      (was already the case for dissipation with mom_vecinv,
943       and also the case for grad.PhiHyd when staggered-timeStep)
944      This will allow to put dissipation out-off the AB time-stepping.
945     Unfortunately, affects truncation error. Update output of exp. that "fails"
946      (cg2d matching number) and leave the others for later: front_relax(10),
947      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
948      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
949    
950    checkpoint57o_post
951    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
952      (2) its ready to be documented during the 20050801 DocFest
953    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
954      for ideal_2D_oce and lab_sea on linux_ia32_g77
955    o set to #undef CTRL_SET_OLD_MAXCVARS_30
956      in global1x1_tot/code_seaice_adj to access indices 32, 33
957      (worth another tag)
958    
959    checkpoint57n_post
960    o adding precip control xx_precip 32
961    o adding swflux control xx_swflux 33
962    o Replacing 10 forcing penalty cost routines by 1 generic.
963    o Implementing partitioning in time-mean and variable adjustment
964      for atmos. state.
965    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
966    o in natl_box_adjoint:
967      * updated exp 1 to 10
968        (but does not have time-mean vs. variable split results yet)
969    o updated global1x1/*_seaice_adj/
970      to incorporate latest changes
971    o enable useSingleCpuIO for mdsio vector routines
972      (applies in particular to tapelev I/O)
973    o removed inefficient K-loop in all active_file*control*.F
974    
975    checkpoint57m_post
976    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
977      and advect_cs (use EXCH-2 and standard cs-32 grid files).
978    o pkg/exch2: filling of face-corner halo regions is optional
979      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
980    
981    checkpoint57l_post
982     tag before updating tutorials (pre-release-2)
983    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
984       for output and interpolation of input fields onto model grid)
985    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
986       Affects results of exp. rotating_tank ; update output.txt.
987    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
988          and taking the square quantity and/or using a fraction-weight field.
989    o fix aim_diagnostics_init.F mate numbers.
990    o add mnc output capability to diagnostics/diagstat and update
991      our cvsignore files for the ACSII output generated
992    
993    checkpoint57k_post
994    o lab_sea now uses diagnostics package and provides a suite of
995      new EXF diagnostics output.
996    
997    checkpoint57j_post
998    o exf
999      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1000        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1001        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1002      * extended diagnostics output
1003        - now includes all EXF variables
1004        - hs, hl moved to common block
1005        - separate S/R for diagnostics, called after ctrl vector is added
1006        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1007        - EXFqnet contains true Qnet (i.e. includes qsw)
1008      * updated verif. lab_sea, global_with_exf
1009      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1010        to ensure that diagnostics sees a true EXFqnet
1011    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1012    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1013      several times with different frequencies.
1014    o mnc-ify the thsice package as requested by Daniel Enderton
1015      - the monitor--MNC output needs work
1016      - many attributes need to be added (most are currently blank)
1017    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1018      - many attributes need to be added (most are currently blank)
1019    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
1020    o add Sadourny like discretization to the 4th.O vorticity advection scheme
1021    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
1022      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
1023         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
1024    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
1025     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
1026    
1027    checkpoint57i_post
1028    o Diagnostics package was changed: diagnostic allocation is now deactivated
1029      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1030    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1031      add 1rst Order upwind vertical Shear.
1032    o add a quick fix for A/B checkpointing in OFFLINE mode
1033    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1034      end-run around the C/Fortran linking horror in eesup/src/timers.F
1035    o added pkg/runclock: allows user to terminate run based on wall clock
1036    o added non-hydrostatic scaling parameter: nh_am2
1037    o pkg/my82: futile attempt to make results compiler-independent by adding
1038      some "_d 0", etc. no effect.
1039    o for mnc output, fill the 'T' coordinate var with myTime and create a
1040      separate 'iter' variable for iteration count
1041    o pkg/diagnostics:
1042      add new capability: output of Global/Regional & per-level statistics ;
1043      tested against monitor output (including land & thSIce) on various exp.
1044    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1045    
1046    checkpoint57h_done
1047      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1048      data.diagnostics, data.gchem, data.ptracers) is done.
1049    
1050    o pkg/diagnostics: prepare for Global/Regional statistics.
1051      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1052    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1053      and rename it: DIFFERENT_MULTIPLE
1054    
1055    checkpoint57h_post
1056    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1057    o pkg/diagnostics: change output frequency, now in seconds (instead
1058      of Nb of iterations). This requires to change data.diagnostics.
1059    checkpoint57h_pre
1060    
1061    o in mnc, let the user create the output dir if both mnc_outdir_date
1062      and mnc_outdir_num are false
1063    o add fflags() to pkg/diagnostics which allows one to specify, on a
1064      per-file basis, the file precision [default behavior is unchanged]
1065    o added diagnostics to pkg/kpp, including computation of mixed layer
1066      depth based on a temperature/density criterion
1067    o updated verification/natl_box to test the new pkg/kpp diagnostics
1068    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1069    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1070    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1071      not mnc -- this mistake was found by JMC and is now corrected
1072    
1073    checkpoint57g_post
1074    o add Adams-Bashforth 3rd Order time stepping:
1075      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1076      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1077    checkpoint57g_pre
1078    
1079    o make lambda[Theta,Salt]ClimRelax spatially varying
1080      (default remains spatially uniform constant based on tau)
1081    o added new control variables
1082      * init. uVel, vVel, etanN
1083      * lambda[Theta,Salt]ClimRelax
1084    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1085      (suggested by G. Forget)
1086    
1087    checkpoint57f_post
1088    o add parameter "baseTime" = model base time = time at iteration zero
1089      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1090      account for baseTime shift
1091    o move Coriolis arrays from PARAMS.h to GRID.h
1092    checkpoint57f_pre
1093    
1094    o mnc-ifying the seaice package
1095    o introduced an alternative length scale calculation for use in the limiting
1096      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1097    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1098    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1099      as well as grad(vort3).  Made it compatible with both approximate form
1100      for the cubed sphere and full form of these gradients.  Added flag
1101      useFullLeith to select between approximate and full form.  
1102    o add "d0" in getcon.F to reduce differences between compilers/platforms
1103      update output.txt of exp. fizhi-gridalt-hs
1104    o change port_rand funtion to allow to set the seed.
1105    o fix obscure MNC bug involving conversion between reals and integers
1106      - it caused no problems with certain (eg. gcc, ifc) compilers but the
1107        new version is now more standards-compliant
1108    o adjoint-related modifications
1109      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
1110      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
1111      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
1112    
1113    checkpoint57e_post
1114    o Adding eddy stress controls a la Ferreira et al.
1115    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
1116    
1117    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
1118      update output.txt of exp. fizhi-gridalt-hs
1119    o add more "Z" dimensions and associated coordinate vars to MNC
1120    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
1121    o parameter calendarDumps: when set, approximate months (30-31 days) and years
1122      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
1123      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
1124      months and years.  Requires pkg/cal.
1125    o diagnostics: add pickup functionality
1126      - off by default for backwards compatibility
1127      - current version only uses MDSIO -- MNC will be added
1128    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
1129    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
1130    
1131    checkpoint57d_post
1132    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1133    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1134      output from the diagnostics package
1135    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1136    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1137      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1138    o add coordinate variables to the MNC output from the diagnostics package
1139    o change MNC-flags default value: true when useMNC=TRUE
1140    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1141      the ability (off by default) to read the grid information using MNC
1142    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1143    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1144    o do snap-shot diagnostics at the middle of the time-interval (instead of
1145      at the end).
1146    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1147      new test for AIM with thSIce + slab-ocean
1148    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1149    o move state variable diagnostics to the beginning of the time step ;
1150      (note: still needs some work specially for snap-shot diagnostics)
1151      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1152    
1153    checkpoint57c_post
1154    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1155    o generate new output.txt files on faulks with g77 & the new -ieee option
1156    checkpoint57c_pre
1157    
1158    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1159      update output.txt of exp. global_ocean.90x40x15
1160    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1161      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1162    o add saltFlux(+File) forcing capability with periodicExternalForcing
1163    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1164    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1165    o improvements for the MNC output from DIAGNOSTICS:
1166      - correct handling of the unlimitied dimension
1167      - all dims now have associated coordinate variables
1168      - variables located at U, V, and Corner ("Z") points are now written
1169        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1170        *all* data points are output
1171    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1172    o added pkg/seaice/seaice_monitor.F
1173    o mdsio_readfield.F can now read files visible only to master MPI process.
1174    o pkg/seaice: some test code for ice-modified ocean stress
1175    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1176      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1177      spurious negative numbers for precipitation and humidity.  Will cause
1178      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1179    o pkg/ctrl/
1180      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1181        May be enabled via doPackDiag
1182      *  introduce z-scaling of
1183         + gradient (doZscalePack) and
1184         + control (doZscaleUnpack)
1185    o pkg/mdsio/
1186      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1187      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1188    
1189    checkpoint57b_post
1190    o simplify options in diagnostics_fill arguments (remove weird combinations)
1191    o fix MNC coordinate variables so that they now contain per-face index
1192      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1193      general, EXCH2 grids are only aligned to a "local" coordinate system
1194    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1195    o Implement instantaneous output within pkg diagnostics:
1196      setting a negative frequency in data.diagnostics produces
1197     "snap-shot" output (as opposed to time-average if freq > 0)
1198    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1199      NOTE: change ptracer diagnostics name: use 2 characters to work with
1200            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1201    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1202      becomes the coordinate variable for the 'T' dimension
1203    o add CF-style coordinate variables to MNC
1204      - just a first cut:  numbers are meaningless on the cubesphere and
1205        missing along the T axis but otherwise it works!
1206    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
1207    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
1208    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
1209      this is based directly on what the model compute, so that the content of
1210      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
1211    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
1212    o clean up build options files for SunOS, in particular
1213      - remove -traditional from xmakedepend
1214      - change -xarch=v9 to -xarch=native for f77
1215      - restore use of make (not gmake)
1216      - add CC=gcc if using g77
1217    o changes per discussion of AM, JMC, & EH3 today:
1218      - move redundant "grid" variables out of "state" -- in preparation of
1219        creating proper CF-style coordinate variables and in recognition
1220        that any/all grid variables can be easily copied (eg. w/NCO) from
1221        the grid files into any of the other NetCDF files
1222      - *always* output grid variables with MDSIO (this will eventually be
1223        changed)
1224      - output MNC grid file if useMNC is true
1225    o every instance of _END_MASTER() has been found and replaced with
1226      _END_MASTER( myThid ) in order to satisfy certain picky Sun
1227      preprocessors
1228    o re-arrange diagnostics pkg initialisation:
1229     - allow each package to extend the available diagnostics list
1230     - add some checking and fix small problems (multi-threaded, ...)
1231     - new S/R diagnostics_fill (replace fill_diagnostics):
1232       look through the short list of active diag. (instead of the long list)
1233       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
1234    
1235    checkpoint57a_post
1236    o this set of changes restores TAMC compatibility
1237      tested for global_ocean.90x40x15 adjoint on trough
1238      (what a pain)
1239    
1240    checkpoint57a_pre
1241    o some modifs in tools/build_options for sunos
1242    o call ctrl_pack for ctrl at end for optimcycle=0
1243    
1244    checkpoint57
1245    o add horizontal bi-harmonic viscosity for vertical velocity
1246      - new parameter viscA4W (defaults to viscA4)
1247      - affects only non-hydrostatic code
1248      - to be done: no-slip lateral boundary conditions
1249    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1250    o implement Implicit Vertical advection for pTracers
1251    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1252      (implemented also for implicit vertical diffusion & advection)
1253    o OBCS: extend application of tracer open boundary conditions
1254      to a strip beyond the boundary of width Olx/Oly
1255    o add call monitor to TAF set of required calls (flow directives)
1256      and include in natl_box_adjoint
1257    o untangle a few ifdefs related to cost, ctrl, autodiff
1258      untangel a few ALLOW_ECCO_OPTIMIZATION
1259    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1260      (theta2, salt2 in ecco_cost_weights)
1261    
1262    checkpoint56c_post
1263    o OBCS as control variables
1264      - update ctrl_ad_diff.list, obcs_ad_diff.list
1265      - remove balance of obcs controls from default
1266      - fix index bug nobcs in ctrl_init
1267      - fix dummy fields filen in ctrl_pack
1268      - add dummy weights for obcs
1269    o lsopt: comment out fort.94 output
1270    o optim:
1271      - remove unnecessary header files
1272      - adjusted namelists
1273      - add xerbla.F to Makefile
1274    o exf:
1275      - multiple modifications of exf_check_range
1276      - unit change in exf_init_runoff from [m/year] to [m/s]
1277    o mdsio:
1278      - i/o-vector change debugLevel from debLevA to debLevB
1279    
1280    checkpoint56b_post
1281    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1282      is called from DO_THE_MODEL_IO
1283      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1284      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1285      - clean up PTRACERS_WRITE_TIMEAVE a little
1286    o add another verification experiment that tests both the cfc-pkg and
1287      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1288      reactive tendencies treated inline with regular timestepping
1289    o testreport previously did a lousy job of comparing small numbers, so
1290      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1291      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1292      testreport.
1293    o ptracers_monitor: bug fix for MPI
1294    
1295    checkpoint56a_post
1296    o GCHEM: finish reorganizating the package
1297      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1298        (introduces another 3D-array for each passive tracer, but only if
1299        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1300        gchemTendency is not needed because the timestep is done separately)
1301      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1302      - GCHEM is now---more or less cleanly---separate from PTRACERS
1303      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1304        so clear to me how that should be done in a general way.
1305    o CFC: improve formatting of output in CFC_ATMOS
1306    o PTRACERS:
1307      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1308        that ALL experiments with ptracers enable can be checked. This makes
1309        GCHEM_MONITOR obsolete.
1310      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1311        monitorFreq
1312      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1313    o add PTRACERS (PTR0[1-5]) to testreport output
1314    o exf_check_range:
1315      * default changed to .TRUE.
1316      * will check values for niter0 if debLevA, every timestep if debLevB
1317      * STOP in exf_check_range if 'out of range'
1318      * range chosen generous to allow for potential extema
1319      TBD: a version with stricter range
1320           permitted range would be runtime parameters
1321  o GMredi:  o GMredi:
1322    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1323    - 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 1326  o GCHEM:
1326    - move call to GCHEM_FORCING_SEP, so that it is now called before    - move call to GCHEM_FORCING_SEP, so that it is now called before

1328    - introduced a useGCHEM runtime flag and applied it everywhere.    - introduced a useGCHEM runtime flag and applied it everywhere.
1329      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1330        this flag is now only visible within GCHEM-pkg routines.
1331      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1332        be replaced by a 3D array that is computed before thermodynamics; for
1333        this, the tracer ID iTracer had to be included into the parameter list
1334        of ptracers_forcing
1335      - set up forward_step to call gchem_forcing, that will replace
1336        gchem_forcing_int in ptracers_forcing
1337      - cleaning up
1338  o small cleaning of exch2: remove files that are also in eesupp/src  o small cleaning of exch2: remove files that are also in eesupp/src
