4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice:
8     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
9     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
10       It is turned off by default (=-1.), because it changes the results.
11    
12    checkpoint59c
13    o add S/R and diagnostics for oceanic mixed-layer depth
14    o move GMRedi call after all vertical mixing schemes (including KPP)
15    o pkg/thsice:
16     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
17      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
18    o pkg/obcs:
19     - bug fix for balance code
20    o pkg/seaice:
21      - allow values of SEAICE_elasticParm > 1
22      - add new parameter SEAICE_evpTauRelax as an alternative
23        to SEAICE_elasticParm
24      - make lsr boundary conditions free slip (by default), changes result
25      - add code for no slip boundary conditions for lsr
26      - set minimum of zeta to zero (and not 4e8) (changes results)
27      - add a cap on AREA after advecting AREA if seaice_growth is not called
28    o change calculation of Visbeck K:
29      - no longer depend on tapering scheme; instead, compute slope (limited
30        by GM_maxSlope). this is equivalent to what was comuted before with
31        clipping or linear tappering.
32      - fix vertical averaging (wrong by 1/2 level)
33      - leave the old version (but will not be maintained) within
34        #ifdef OLD_VISBECK_CALC / #endif
35      - update output of exp. ideal_2D_oce
36    o change error catch in calc_r_star to improve vectorization
37    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
38      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
39    o adjoint:
40      Re-organized adjoint checkpointing according to Matt Mazloff
41      (but with modifs/completions/cleanups)
42      Storing is now bundled into large arrays to optimized I/O
43      (and second step in cleanup of the_main_loop)
44    
45    checkpoint59b
46    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
47      - export/import (between ocean & coupler) fields needed for ocean DIC.
48    o pkg/seaice:
49      - get rid of three more exchanges seaice_calc_viscosities (required
50        different loop boundaries in seaice_lsr and seaice_ocean_stress)
51      - bug fix in seaice_ocean_stress (update of lab_sea required)
52      - reduce loop boundaries to necessary minimum also in seaice_evp
53      - go back to the old way of computing deltaC/Z as the adjoint likes that
54        better
55    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
56      passive tracer to an Age Tracer) + update output.txt
57    o pkg/exf:
58      - implement A-grid / C-grid selection for wind-stress input files.
59      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
60      for now, in exf_bulk_largeyeager04.F only :
61      - change implementation for case where windspeed + 2. components wind-stress
62        are read-in. AND use rhoConstFresh to convert evap.
63    o pkg/seaice:
64      - use correct EXCH_UV for wind-forcing (on A-grid).
65      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
66        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
67    o pkg/exf:
68      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
69      EXF_INTERPOLATION:
70      - merge global_with_exf/code version of exf_interp_read.F
71        to the main code ;
72      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
73        reading the file ; Important: This options needs to be defined to recover
74        previous code.
75        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
76      - no longer loose real*8 precision along the way when using exf_iprec=64.
77    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
78      - change discretisation of evp-solver in order to avoid another exchange
79        (changes lab_sea) and clean up a little
80      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
81        help the adjoint (this also changes the results slightly)
82      - add a few "_d 0" where they had been missing in seaice_evp.F
83      - cleaning up: remove unused seaice_calc_rhs.F
84    o pkg/exf: some cleaning-up:
85      - change various "constants" into runtime parameters
86      - cleaned-up Large&Yeager04 routine which should eventually
87        replace exf_bulkformulae.F (changed names of S/R and CPP)
88        and merged various ALLOW_ATM_WIND options
89     only used with thsice pkg (in thsice_get_exf.F):
90      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
91        which are used when useStabilityFct_overIce=TRUE (= the default)
92      - change default values of ice & snow emissivity and scale downward LW
93        by ice & snow emissivity.
94    o pkg/thsice:
95     fix few little problems, in thsice_calc_thickn.F:
96      - growth vertically (and not laterally) if iceFrac == iceMaskMax
97      - melt only laterally if hIce < hThinIce (as the comments say)
98      and in thsice_extend.F:
99      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
100      - start to form ice as soon as the minimum ice-volume is reachable.
101     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
102      and cpl_aim+ocn
103    o pkg/kpp
104     - move computation of surface related input fields to KPP into a new
105       subroutine kpp_forcing_surf.F
106     - remove wrong (within bi,bj loops) EXCH calls.
107     - little cleaning (add argument myThid in last position, cvs header ...)
108     - for now, fix conservation problem by exchanging KPPviscAz (may not
109       be the best fix)
110    o pkg/seaice
111     - check for inconsistent evp parameter/cpp-flag combination
112     - remove leftover errIO flat for obsolete name list error handling
113    o OpenAD
114     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
115    
116    checkpoint59a
117    o pkg/seaice: some parameter clarifications and a little bit of clean up
118    o pkg/thsice: rename run-time parameters:
119       himin       -> hIceMin
120       himin0      -> hThinIce
121       hihig       -> hThickIce
122       i0          -> i0swFrac
123       transCoef   -> bMeltCoef
124       frac_energy -> fracMelting
125      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
126       with default values (for now) that do not change the results.
127      remove old version of thsice vars advection in pkg/seaice.
128    o in FFIELDS.h:
129      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
130      - make pLoad & sIceLoad always available (but still only used if
131         ATMOSPHERIC_LOADING is #define).
132    o pkg/kpp: replaced _KPP_RL with _RL
133    o bug fixes for vertical diffusivity computations when both KPP and
134        3D diffusivity arrays are used.
135    o pkg/seaice: fix bug in evp solver, while doing that
136      - change (improve?) discretization of stress computations for both
137        cgrid-lsr and evp solver
138      - add a new routine to compute strain rates
139      - the above changes lab_sea results
140      - add no slip conditions for evp solver (off by default), lsr-version
141        may follow
142      - fix exchange for shear at Z-points (does not change lab_sea)
143      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
144        (to force the user to pick a time step since there is not "safe" way
145        of choosing it)
146      - add principal stress diagnostics
147      - rearrange fields for evp a little to avoid having to call a: too many
148        exchanges and b: exchanges for stress trensor components which we do
149        not have.
150      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
151        of evp, complete rewrite for lsr case (latter is does not yet work
152        in all cases)
153    o pkg/kpp: add code to have mixing in shelf ice caverns
154      - add myThid to all kpp routines (long overdue)
155    
156    checkpoint59
157    o pkg/exf:
158      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
159        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
160      - move exf header files from lower_case.h to UPPER_CASE.h ;
161        add missing cvs Header & Name
162      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
163      - add namelist param. selectStressGridPosition, exf_monFreq
164      - retire many _CLIM routines, and remove data.exf_clim
165        + params moved to data.exf
166        + climsst, climsss now handled by exf_set_gen, i.e.
167          climss?period=0 refers to constant field,
168          climss?period=-12 to monthly forcing
169      - split up namelists in data.exf
170    o pkg/seaice:
171      - remove seaice_exch and seaice_exch_uv
172      - remove superfluous exchange of theta
173      - add myThid to seaice_budget_ocean/ice
174      - add new interface for atmospheric wind forcing (C-grid only)
175        + new routine
176        + two new field (taux, tauy for stress over ice)
177        + removed one global field (DAIRN) for C-grid case only
178    o pkg/thsise
179      - 2nd set of modifs for thsice adjoint in conjunction with exf
180    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
181    
182    checkpoint58y_post
183    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
184      vertical diffusivity, similar to that in MOM4; turned on using
185      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
186      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
187    o Added capability for 3D specification of background vertical diffusion
188      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
189      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
190      "data" file that contains the 3D vertical diffusivity coefficients.
191    o ice dynamics (pkg/seaice) with thsice thermodynamics:
192      - add code within pkg thsice to advect & diffuse sea-ice fields
193      similar to (and will replace) what has been added in  seaice_advdiff.F,
194      but: - conserving Mass, Heat & Salt.
195           - better when using non-linear advection scheme (not yet fully tested)
196           - can also be used in atmospheric set-up (for now, only the diffusion).
197    
198    checkpoint58x_post
199    o IO option for global-file compact format:
200      - add options when generating topology (utils/exch2/matlab-topology-generator)
201      - add I/O capability (pkg/mdsio).
202      - adapt utils/matlab/rdmds.m to read this format.
203      for now long-line format not yet supported by pkg/mdsio (& exch2).
204    o shelfice: add a few diagnostics
205    
206    checkpoint58w_post
207    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
208      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
209      (and replace horiVertRatio in NH code).
210      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
211                         and tutorial_plume_on_slope (sensitive to truncation)
212    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
213      directly to drive seaice model (C-grid only)
214    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
215     - reintroduce computation of wind from stress,
216     - compute tau (in exf_bulkformulae.F) from windstress averaged to
217       mass points to avoid tau = 0
218     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
219    o rdmnc.m: make it work with "global" files created with gluemnc
220    o rdmnc.m : some improvements in dealing with singleton dimension
221      (tested on all testreport mnc output files).
222    o genmake2: disable pkg/profiles if netcdf test fails.
223    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
224    o move call to cal_readparms up to make calendar parameters/variable available
225      to all packages
226    
227    checkpoint58v_post
228    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
229      useDynP_inEos_Zc tested.
230    o pkg/exf: changes to properly interpolate/mask/scale initial fields
231    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
232      and portions thereof.  See read_cs.txt for description and examples.
233    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
234      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
235      following the great-circle arc between those 2 points.
236    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
237      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
238    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
239     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
240     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
241     - still needs work (not working with some options ; efficiency to improve)
242       and serious testing.
243     - use this scheme for temperature & salinity in 2 advection test exp.:
244       advect_xy & advect_xz, respectively.
245    
246    checkpoint58u_post
247    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
248    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
249    o testreport: add option "-skipdir" to skip some test.
250    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
251      momentum calculation.
252    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
253    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
254      remove checkpoint.F and the_correction_step.F (no longer used);
255      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
256    o add option (linFSConserveTr) to correct for tracer source/sink due to
257      Linear Free surface
258    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
259    o pkg/thsice: fix reading mnc-pickups
260    
261    checkpoint58t_post
262    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
263    o pkg/mdsio:
264     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
265       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
266       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
267     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
268     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
269       either MDS_READ_FIELD or MDS_WRITE_FIELD )
270     - new S/R (to replace MDSWRITEMETA), which allows to write more
271       informations (variable names, time ...) to meta files.
272     - modify rdmds.m to give back the meta file content.
273    o pkg/diagnostics: change vertical interpolation to be safer, and more
274       flexible (define p-levels to interpolate to in data.diagnostics);
275      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
276       diagnostic pointer.
277    o pkg/seaice: more cleaning up of seaice_growth, added many comments
278    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
279    o fix multi-category seaice:
280     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
281       SEAICE_MULTICATEGORY
282     - fix short wave heat flux
283    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
284       and allow to use EVP solver. Change forward lab_sea: test both EVP
285       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
286    o Initial check-in of lab_sea adjoint
287      (very similar to natl_box_adjoint/code_seaice)
288      * used C-grid and EVP solver
289      * used KPP, GM/Redi
290      * uses inAdExact=.TRUE.
291      * gradient checks fail for both ADM and TLM
292        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
293        f.d. gradients actually seem more problematic than ADM, TLM gradients;
294        issue is related to forward mismatch between g77 an ifort
295    o pkg/seaice: overhaul of thermodynamics
296     - growth.F and groatb.F are replaced by new routine seaice_growth.F
297     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
298     - move a few global fields out of SEAICE.h into seaice_growth.F and
299       make them 2D (FICE/QNETO/ ...)
300     - remove FO (it is the same as QNETO)
301     - introduce a few local fields to avoid modifying external fields such
302       as atemp, etc.
303    
304    checkpoint58s_post
305    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
306      changed exf_set_gen.F so that
307        genperiod=0 means input file is one time-constant field and
308        genperiod=-12 means input file contains 12 monthly means
309    o CG2D: use pre-computed solver main-diagonal (stored in common block);
310      this affects truncation error ; generate new output file for exp. which
311      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
312        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
313        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
314        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
315        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
316        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
317    o start implementation of deep-atmosphere and anelastic formulation
318    o verification: remove 2nd copy of input files and use script "prepare_run"
319      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
320    o mom_common/vecinv/fluxform: fix a few initialisation isssues
321    o profiles: fix for multithreaded case
322    
323    o diagnostics: rename few diags:
324      s/'PRESSURE'/'RCENTER '/g
325      s/'TICE    '/'oceFreez'/g
326      s/'TAUX    '/'oceTAUX '/g
327      s/'TAUY    '/'oceTAUY '/g
328      s/'SWFLUX  '/'oceQsw  '/g
329      s/DIFx/DFxE/g
330      s/DIFy/DFyE/g
331      and add few ocean-forcing diagnostics:
332      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
333    o modifications to pkg/seaice/growth.F and budget.F, which change results of
334      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
335      as actual snow thickness.  It now refers everywhere to effective snow
336      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
337    
338    checkpoint58r_post
339    o modifications to pkg/seaice/growth.F, which change results of
340      lab_sea experiment: fixes pertain to melting snow over open water, to
341      masking EVAP under sea ice, and to using the correct AREA variable for
342      computations of EVAP, PRECIP, HSNOW, and GHEFF
343    o add ability to read bathy, salt, and theta using MNC (off by def)
344    o add flooding algorithm and advection of HSNOW for pkg/seaice;
345      both are turned off by default and do no change any results
346    o seaice advection with pkg/thsice: a step toward the use of non-linear
347      advection scheme, but #ifdef or commented out for now (requires more EXCH).
348    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
349      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
350      in natl_box (affects results @ truncation level: update output.txt)
351    o multi-threading and IO:
352      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
353      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
354        (needed to work with SingleCpuIO): tested in all verif. exp.
355    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
356      affects the results (but none of the verification test uses this scheme).
357    o Adding some pkg/diagnostics capability to pkg/seaice
358      (will certainly be subject to changes)
359    o ctrl: adding new control variables:
360      lwflux, lwdown, evap, snowprecip, apressure, runoff
361    
362    checkpoint58q_post
363    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
364      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
365      high_res_cube configuration by 4% on Columbia.
366    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
367      add (in global_with_exf/code) a version of EXF_INTERP_READ without
368      dynamical allocation (seems to work in multi-threaded).
369    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
370      single CPU io) so that TAF does not have to see EESUPPORT.h
371    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
372    
373    checkpoint58p_post
374    o obcs: stop if obcs is used with useCDscheme = .true.
375    o shelfice:
376     - fix a sign error so that no slip at shelfice interface works
377     - remove stop for combination non-hydrostatic code and shelfice. That does
378       not mean, that the results are correct, but at least they are numerically
379       stable
380    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
381    o added adjoint exch routined for all exch*3d* routines
382      and updated flow directives
383    
384    checkpoint58o_post
385    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
386      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
387    o change controling S/R for writing pickup file (new S/R do_write_pickup)
388      and clean-up reading/writing of pickup files.
389    o fix local version of read/write pickup (NH part) in rotating_tank/code
390    o simplify EXCH interface:
391     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
392     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
393    o added the regrid package
394    o shelfice:
395     - add a simple boundary layer scheme to reduce noise
396     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
397    
398    checkpoint58n_post
399    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
400       local variable (not in common block).
401    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
402      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
403      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
404        to work with SingleCpuIO.
405    o add "_d 0" to real constant of pkg/cfc subroutines ;
406       update exp. cfc_exemple & tutorial_cfc_offline output files.
407    o multi-threading and IO:
408      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
409        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
410      - barrier before and after reading.
411      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
412      - avoid using MDS_WRITELOCAL for LAND pkg output.
413      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
414        common-block variables ; Allows multi-threading with master-thread IO.
415    o change default MAX_NO_THREADS from 32 to 4 ;
416      and stop cleanly when MAX_NO_THREADS is too small.
417    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
418    
419    checkpoint58m_post
420    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
421       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
422    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
423       keep global_ocean.90x40x15 (for AD testing) with former secondary test
424       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
425    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
426        add MITgcm_tutorials (= code + all the tutorials)
427    o ecco, option to compute cost for total ssh (mean+anom)
428    o consistent with addition of ptracer and ssh in pkg/profiles
429    o profiles: adding ptracer and ssh
430    o testreport: change multi-test output-file name
431      (from output.txt.{name} to output.{name}.txt)
432    o profiles: now ok for mutli-tiles case
433    o seaice: add 4 parameters for different advection schemes for area,
434      (effective) seaice thickness, enthalphy, and snow height. Their default
435      is the standard parameter SEAICEadvScheme
436    o calc_gw:
437     - add cosFacU in zonal viscous flux (harmonic.visc.).
438     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
439       of tutorial_plume_on_slope.
440    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
441    o calc_gw: true flux-form, account for horizontal grid spacing.
442      update rotating_tank results, but not plume_on_slope (affected at
443      truncation level, 11 digits).
444    
445    checkpoint58l_post
446    o calc_gw:
447     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
448     - remove side-drag for now (need to fix it); update plume_on_slope results.
449     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
450    o commit code to make SST/SSS weights spatially variable
451      (based on either variable in-situ or variable initial T/S weights)
452    o pkg/ecco:
453      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
454        now based on horizontally varying weights wthetaLev, wsaltLev
455      * cost_averagesflags now returns year indices in addition to day, month
456      * sflux balance is performed on annual basis
457        (sflxumm, sfluxmm2, bal_sfluxmm)
458      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
459        including separate counting and multipliers
460    o pkg/rbcs
461      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
462    
463    checkpoint58k_post
464    o testreport:
465     - always build in dir. "build" (if not there, mkdir build instead of building
466       & running in input)
467     - run in dir run (if it exists), in build otherwise.
468     - call prepare_run (if input/prepare_run exists)
469     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
470    o pkg/exf modifications to interpolation and rotation routines for more
471       reasonable treatment of North Pole singularity: for tracers North Pole
472       value is set to northernmost zonal-mean value, for zonal velocity it is
473       set to zero, and for meridional velocity it is set to northernmost value.
474    o pkg/exf/exf_check_range.F
475     - add tile index to diagnostics and move stop statement to the very
476       end of the routine.
477    o pkg/diagnostics: (diagnostics_main_init.F)
478      define title of isomorphic variables according to the current config.
479    o pkg/thsice with pkg/seaice dynamics:
480    - fix domain of computation (interior only, required for exf) and do exchanges
481    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
482    o towards a standard way of dealing with multi-threading in MONITOR
483      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
484    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
485       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
486    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
487    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
488    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
489       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
490    o tracer advection:
491     - clean-up and simplify calc_common_factors.F
492     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
493       advection subroutine (but still not used within DST advection S/R)
494    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
495    
496    checkpoint58j_post
497    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
498      from file (collects calls previously in FORWARD_STEP)
499    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
500    o adjoint store dir. adjusted accordingly
501    o genmake2
502      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
503    
504    checkpoint58i_post
505    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
506      on wind stress (SEAICEstressFactor defaults to 1.)
507    o Total number of Timers is finite (<=40): comment out 2 non-essential one
508      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
509    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
510      on CS-grid: no longer loosing mass.
511    o exf & curvilinear-grid: no longer modify longitude xC & xG.
512    o pkg/ggl90: fix sloppy output and fix a bug
513    o pkg/seaice: added SEAICEuseEVPpickup parameter
514      - Set to false in order to start EVP solver with
515        non-EVP pickup files when using SEAICEuseEVP
516      - fix sign error in diffusion in seaice_calc_rhs
517    
518    checkpoint58h_post
519    * Modifications for bottom topography control
520      o replace hFacC by _hFacC at various places
521      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
522      o add non-self-adjoint cg2d_nsa
523      o update autodiff support routines
524      o re-initialise hfac after ctrl_depth_ini
525      o works for 5x5 box, doesnt work for global_ocean.90x40x15
526    * Adding verification for 5x5 box (4-layer) bottom topography control
527    
528    checkpoint58g_post
529    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
530       used for mean seasonal cycle, mean diurnal cycle); add an example
531       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
532    o pkg/ggl90:
533      - add parameter (minimum surface kinetic energy)
534      - fix bug (avoiding division by zero)
535    o couple pkg/thsice to pkg/seaice:
536      - modify advection in seaice to accomodate new scalar fields to be advected
537      - only muliDimAdection scheme work with seaice/thsice
538      - mapping of thsice-variables to seaice-variables, back and forth
539      - does not break the verification experiments, but does not give the
540        desired results either
541    o pkg/seaice
542      - make (default) second order advection a bit less confusing?
543    
544    checkpoint58f_post
545    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
546      to pkg/seaice):
547      - new routines thsice_map_exf and thsice_get_exf provide the interface
548      - add an additional formal parameter to thsice_solve4temp
549    o pkg/exf:
550      - add new fields wspeed, snowprecip (to be able to couple to thsice)
551      - correct Stefan-Boltzmann constant
552      - new parameter for longwave surface emittance
553      - separate some stuff from exf_bulkformulae into new routines  
554        exf_radiation, exf_wind
555      - add new parameters and constants: longwave emissivity for ocean, ice
556        and snow, evaporation parameters over ice
557      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
558        either wind from stress or stress from wind
559    o pkg/thSIce:
560    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
561    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
562       and THSICE_CALC_THICKN
563    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
564    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
565      to make debugging easier.
566    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
567    o pkg/bulk_force:
568      - clean-up comments and parameters ;
569      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
570    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
571      generate new output for test-experiment: aim.5l_cs.thSI
572    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
573      testreport accordingly
574    
575    checkpoint58e_post
576    o SEAICE_CGRID adjoint done
577    o R_STAR adjoint implemented.
578      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
579      * need to sort out init. of h0facc, etc.
580    o Make pkg/profile fully independent of ecco,cost, etc. stuff
581      to be able to use it in pure forward.
582    
583    checkpoint58d_post
584    o upgrade simple test-experiment to tutorial example:
585     step.1: duplicate the experiment and (step.2) will remove the old copy.
586      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
587      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
588      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
589      tutorial_global_oce_biogeo    <- copy of dic_example
590      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
591      tutorial_plume_on_slope       <- copy of plume_on_slope
592      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
593      tutorial_global_oce_optim     <- empty for now (David ?)
594      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
595     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
596    o correct a sign problem in cost_scat.F
597    o obcs and ptracers: fix boundary conditions for advections schemes
598      with larger stencil
599    o thsice adjoint: start
600    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
601      completeness
602    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
603      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
604    o ptracers adjoint:
605      * avoid extensive recomputatations
606      * fix missing re-init. of gptr (missed by TAF)
607    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
608      me to turn off the excessive output to STDOUT that this package produces
609    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
610      and add those terms in Vector-Invariant formulation.
611    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
612      if the control period (xx_hfluxperiod etc) is 0
613    o in profiles pkg, clean routines and fix details
614    o in ecco pkg, reading ssh data:
615      fix problem in case the model does not start at iter0=0
616    o fix mnc-pickup/restart for ptracers
617    o new package prifiles:
618      code to compute profile-based cost by Gael Forget
619      (modifs in ecco, ctrl, autodiff)
620    o Benign bug fix in initialization (spotted by M. Mazloff) of
621      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
622    
623    checkpoint58c_post
624    o adjoint: finish NLFS adjoint and provide reference output in
625      verification/global_ocean.90x40x15/results_ad_nlfs
626    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
627      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
628      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
629      with SEAICE_CGRID defined.
630    o move calendarDumps from "data" to "data.cal" and clean-up the code
631      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
632    o add useEXF & useCAL flags (for now, set in hard-coded way)
633    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
634      (were missing in NH mode, and wrong in quasihydrostatic mode).
635      waiting for Chris updated version of calc_gw to add those CALLs.
636    o fix bug in quasihydrostatic S/R ;
637      add a test for this option: global_ocean.90x40x15.qshyd
638    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
639      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
640    o add on/off flag useOffLine for package OFFLINE
641    o seaice:
642      - modify advection so that it works also on the C-grid
643      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
644        problem in multi-tile runs with C-grid
645      - add flags for clipping ice velocities and/or masking solver forcing
646      - fix drag (ocean on ice) formulation and a bug that caused noise in the
647        C-grid solver
648      - added a few comments to seaice_diffusion.F
649      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
650        are now exclusive)
651      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
652        required re-ordering the code a little:
653       + make DAIRN global variable (defined in SEAICE)
654       + move computation of the viscosities eta and zeta into a new separate
655         routine (because I need to recompute them in seaice_ocean_stress.F)
656    
657    checkpoint58b_post
658    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
659      update output.txt of exp. aim.5l_cs.thSI
660    o various mnc cleanups and improvements:
661      + shrink lookup tables by factor of ~4
662      + better error reporting when running out of lookup space
663      + able to handle longer path/file names (up to 500 chars)
664    o adjoint:
665      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
666      - TBD: "hidden" mom_vecinv recomp. in dynamics
667    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
668     (allow to differentiate between forcing components using new integer flags:
669      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
670     and add new flag to put Dissipation tendency out of Adams-Bashforth.
671    o ecco
672      - enable trend removal from SSH anomaly obs.
673    o adjoint
674      - a fix for PmEpR when #undef EXACT_CONSERV
675      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
676      - try to fix "hidden" recomp. in forward_step for NLFS
677        (NLFS seems broken sometimes after I checked it in)
678    o seaice:
679     - add c-grid version of the dynamic solver:
680       + three new routines that are the c-grid substitute lsr, dynsolver
681         and ostres
682       + put a few fields that were local to dynsolver into global common
683         blocks, so that I can move the computation of stresses etc into
684         seaice_lsr (saves coding but may break the adjoint).
685     - replace more hardwired parameters by runtime parameters
686     - add ice masks that mask the rhs of the implicit solvers where there
687       is no ice (commented out in seaice_dynsolver, because i am not sure
688       if this works properly), eventually this should replace the clipping
689       of ice velocities in seaice_dynsolver to +/-40cm/s.
690    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
691      include it only where its needed
692    o move balancing of fluxes before the call of external_forcing_surf
693    o seaice:
694      - correct units of turning angles (now they are really in degrees)
695      - move computation of GWATX/Y out of main routine into dynsolver
696      - initialize GWATX/Y in seaice_init
697    o Apply mask on Fresh-Water flux (needed for SSH forcing).
698      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
699    o seaice: add runtime flags for turning angles (default to zero)
700    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
701      and trend from exf forcing and ctrl control adjustments
702    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
703      (since checkpoint57x_post)
704    o change the default rotation period to 86164.s = the Earth rotation
705    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
706      and based on a reference stratification. Tested within hs94.cs-32x32x5.
707    o seaice advection: add code for choosing between the default (2nd order
708      central differences) and multiDim advection schemes provided by
709      pkg/generic_advdiff
710    o seaice:
711      - removed all references to SEAICE_GRID.h fields from
712        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
713        (cubed-sphere configuration will change a little)
714      - grid computations in seaice_init are obsolete now.
715      - cleaned up code a little so that is easier to read (hopefully).
716      - added new (better?) discretizations of default advection and diffusion
717        (turn on with SEAICEuseFluxForm)
718      - replace 1 in 3d global fields by kSurface in growth.F
719      
720    checkpoint58a_post
721    o seaice:
722      - bug fix in advect.F
723    o shelfice:
724      - separate shelfice load anomaly from pload (breaks with time
725        dependent forcing), => introduce constant field shelficeLoadAnomaly.
726        Its default is 0., but it may be computed more cleverly from (unknown)
727        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
728        done offline. A good approximation of the pressure load anomaly is
729        necessary to avoid large initial adjustment processes underneath
730        deep-reaching shelfice.
731      - small fix in ISOMIP shelfice_thermodynamics
732      - add more sophisticated thermodynamics of Hellmer (1989), this is
733        now the default
734      - give a few constants more intuitive names
735    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
736      if bulk formulae are used in long integration (especially EmPmR). Turn
737      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
738      if balancePrintMean, the imbalance that is substracted is printed to
739      STDOUT.
740    o fix bug (typo) in obcs_apply_eta.F
741    o add a new package shelfice which enables us to model the circulation
742      underneath shelf-ice with draughts of hundreds of meters.
743     - works
744     - to do: + include improved thermodynamics
745              + check whether kSurfC (from model/inc/SURFACE.h) can be used
746                instead of new field kTopC
747              + can we use topoFile, Ro_surf and existing code in ini_depth.F
748                instead of new field R_shelfIce and new code in ini_depth.F
749                and ini_mask_etc.F?
750              + adjust vertical mixing schemes?
751    o seaice pkg:
752     - add a cpp-flag to include a simple formula for a salinity dependent
753       freezing point of sea water at the surface
754     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
755       meridional stresses are now different (and hopefully correct)
756    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
757       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
758       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
759    o pkg/diagnostics: add options and parameters for regional-statistics
760       diagnostics ; define regions by reading a region-mask from a file
761       (might add other options later)
762    o pkg/bulk_force:
763     - add option and parameters to use AIM surface-flux formulae.
764     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
765       others forcing fields (defined in PARM05, parameter file "data") are loaded
766       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
767     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
768     - use the right EXCH call for uwind,vwind (to work on CS-grid).
769     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
770       and parameters (note: calcWindStress replaces .NOT.readwindstress).
771     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
772    
773    checkpoint58
774    o add "--embed-source" option to genmake2 which, when the supporting
775      tools can be compiled (as determined by genmake2) will turn on the
776      embed_files package which then embeds the entire MITgcm source code
777      (*.[fFhc] + Makefile) used for the build within the executable
778      - requested by CNH but off by default
779      - adds a paltry <9MB to the mitgcmuv executable in most cases
780      - only writes the output when useEMBEDSRC in eedata is true
781    o clean up 3-dim. relaxation codes:
782      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
783      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
784      * Thanks to Tom Haine for testing!
785    
786    checkpoint57z_post
787    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
788      affects output (@ truncation level) of exp. plume_on_slope ; updated.
789    o fix the pickup behavior for obcs in combination with ptracers
790    o fix a bug in ptracers_external_fields_load
791    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
792      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
793    o transfered surface NH pressure to eta field (if exactConserv).
794    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
795         and update lab_sea output.txt file.
796    o completing 3-dim. relaxation code: additional term
797         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
798      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
799      * At compile time, in "EXF_OPTIONS.h" set
800          #define  ALLOW_CLIMTEMP_RELAXATION
801          #define  ALLOW_CLIMSALT_RELAXATION
802      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
803          tauThetaClimRelax3Dim = 15552000.0,
804          tauSaltClimRelax3Dim  = 15552000.0,
805      * 3 cases:
806          1) Use a constant-in-time 3-dim. field
807          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
808          3) Real-time relax. to time-evolving prescribed field
809    o Adding Laplacian-type smoothness constraint on
810      initial and boundary (forcing) controls (ic, bc)
811      * enable at compile-time via
812        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
813      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
814      * Absolute scale somewhat unclear so far
815      * no area weighting was included since no other cost term does so far
816    
817    checkpoint57y_post
818    First step for a NLFS adjoint
819    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
820    o new init. routines for calc_r_star, calc_surf_dr
821    o still need to deal with ini_masks_etc
822    o testreport seemed happy
823    checkpoint57y_pre
824    
825    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
826    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
827    o add new offset feature to offline pkg (plus minor cleanup)
828    o cfc fixes for final year of integration
829    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
830      be in GCHEM_OPTIONS).
831    
832    checkpoint57x_post
833    o fix testreport Pb in multiple test experiment.
834    o cleanup our namelist syntax in verification:
835      - make it more F95 standards compliant (some work still needed)
836      - allows the vast majority of our tests to work with gfortran
837    o Non-Hydrostatic:
838     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
839     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
840    o Allow to apply AB on T,S rather than on AB(gT,gS):
841     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
842     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
843       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
844     - need a "clever" read_pickup to restart from the other AB formulation
845    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
846    o remove some unused variables (reduces number of compiler warnings)
847    o adjoint
848      * Disable useVariableViscosity for adjoint for time being
849        (there are a number of extensive recomputations)
850      * Initialize certain variables needed for adjoint
851    
852    checkpoint57w_post
853    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
854                 fix the singleCpuIO RS version of MDSWRITEFIELD
855       and add a WARNING if using globalFiles=T with multi-processors.
856    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
857      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
858    o tracer advection scheme:
859      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
860       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
861       was not very convenient).
862      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
863       (further tests needed for the implicit DST & Flux-Limiter schemes).
864    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
865      and sRef for convenience, handy, when you want to initialize
866      ptracers in a large domain with a constant non-zero value. Also,
867      untangle ptracers_init.F a little.
868    
869    checkpoint57v_post
870    o change dome exp. to use variable viscosity in side-drag terms.
871    o remove all the files from the cfc_offline test since they are now
872      incorporated into tutorial_cfc_offline which has been producing
873      identical results for a few days of testing
874    o add new parameter: sideDragFactor to enable half-slip-side BC
875      and change side-drag S/R to use viscosity from mom_calc_visc
876      (can switch back by setting sideDragFactor=0.); affects results at
877      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
878       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
879    o vorticity & strain are now computed without masking, to account for
880      no-slip-side BC in variable viscosity calculation ; mask is applied
881      anyway later on, before computing advection/coriolis terms.
882    o modify exp4 to test new obcs support for reading from external files
883      and for passive tracers
884    o fix behavior of ptracers_monitor when monitor output is written to a
885      netcdf-file; still not independent of monitor.F (writes in the same
886      file).
887    o change default value of tRef (put a uniform, meaningful value for ocean
888      & atmos) and initialize sRef (was missing, as Martin mentioned).
889    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
890      to be proportional to enstrophy dissipation length.  Thus,
891       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
892      This is now consistent with Smagorinsky and with the manual.
893    
894    checkpoint57u_post
895    o OBCS and PTRACERS: add open boundary support for passive tracers
896      - either use homogenous (pseudo) v.Neumann conditions or prescribe
897        OB-values from file; this is not different from the way theta and salinity
898        are treated
899      - however, Orlanski-radiation conditions are not supported, and the model
900        will stop if you use pTracers and Orlanski at the same time.
901      - beefed up the rountine obcs_external_fields_load: now only those open
902        boundary values are overwritten with values from files for which there
903        are really files, otherwise the OB-fields remain untouched. This makes
904        it possible to use different OBs at different ends of the domain (as
905        with EXF)
906    o reduce number of exch calls in shap_filt (s2).
907    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
908      truncation level) 4/5 MLAdjust test results (11&12 digits match).
909    
910    checkpoint57t_post
911    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
912    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
913      same truncation, independent of the face number: affects affects several
914      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
915    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
916      note that biharmonic viscosity + no-slip was not tested in any experiment.
917    o fix bug in non-linear free-surf side-drag ; generate new output for
918      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
919    o make mnc honor the writeBinaryPrec flag for most kinds of output
920    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
921    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
922      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
923    o add brackets in multi-terms sum to get same truncation, independent of
924      the face number (manage to get exactly same value of gU,gV at the cs-edge)
925      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
926    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
927      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
928      a maximum grid-scale Reynolds number.  Also, changes all length calculations
929      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
930      Suggested values of viscosity parameters found in mom_calc_visc.
931      Many new viscosity diagnostics available.
932    
933    checkpoint57s_post
934    o Add clearing-house for viscosity calculations, mom_calc_visc and
935      correct numerous bugs in LeithD and Smagorinsky discretizations.  
936      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
937      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
938      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
939      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
940      The Strain-Tension form is now called with useStrainTensonVisc=.true.
941      ViscAhStrain and viscAhTension are now retired.
942    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
943    o In response to JMC's bug report, genmake2 now ignores any soft-links
944      that it finds in the *current* directory when searching for files.
945      Soft-links found in any other source directories will still work as
946      they did before.
947    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
948      a C routine to unlimit the stack size
949    o mnc-ify pkg/aim snapshot vars
950    o mnc-ify pkg/land as requested by Daniel
951    o various changes to mnc including:
952      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
953      - output can now be grouped so that all files within a group
954          change the ITER portion of their names in lock-step together
955      - can now read ("global") PER-FACE (in addition to PER-TILE) files
956          and works with both EXCH1 and EXCH2 (but needs more testing)
957      - writing works for all verification test cases w/ g77 on Linux
958    
959    checkpoint57r_post
960    o make MNC variable initialization happen earlier
961    o add diagnostics for (almost) each term of the momentum Eq.
962    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
963    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
964    o remove MINIMAL_TAVE_OUTPUT option ;
965      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
966    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
967      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
968    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
969    o add time-dependent SST, SSS control
970    o cost terms in ecco/ modularized (new cost_generic.F)
971    o cost_averages routines are modularized (new cost_averagesgeneric.F)
972    o new infrastructure for seaice model vs. obs misfits in seaice/
973      * driver from the_main_loop.F is seaice_cost_driver.F
974      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
975      * gradient check in Exp. 6a of natl_box_adjoint/
976    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
977      (see README file)
978    
979    checkpoint57q_post
980    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
981    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
982      - bug was reported by Jean-Michel and Ian Fenty
983    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
984      update exp. cpl_aim+ocn output.
985    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
986      Needed for high-res. runs with large global files
987      to be able to limit tapelev size
988    o Changed some tests for adjoint:
989      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
990      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
991      * global_ocean.90x40x15/ back to default 3-level checkpointing
992    o Modifications to enable scripted COMMON to MODULE conversion
993      * verification/OpenAD/code/ has necessary scripts and description;
994      * converts, compiles and runs successfully;
995    
996    checkpoint57p_post
997    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
998    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
999      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1000    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1001    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1002      (was already the case for dissipation with mom_vecinv,
1003       and also the case for grad.PhiHyd when staggered-timeStep)
1004      This will allow to put dissipation out-off the AB time-stepping.
1005     Unfortunately, affects truncation error. Update output of exp. that "fails"
1006      (cg2d matching number) and leave the others for later: front_relax(10),
1007      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1008      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1009    
1010    checkpoint57o_post
1011    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1012      (2) its ready to be documented during the 20050801 DocFest
1013    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1014      for ideal_2D_oce and lab_sea on linux_ia32_g77
1015    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1016      in global1x1_tot/code_seaice_adj to access indices 32, 33
1017      (worth another tag)
1018    
1019    checkpoint57n_post
1020    o adding precip control xx_precip 32
1021    o adding swflux control xx_swflux 33
1022    o Replacing 10 forcing penalty cost routines by 1 generic.
1023    o Implementing partitioning in time-mean and variable adjustment
1024      for atmos. state.
1025    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1026    o in natl_box_adjoint:
1027      * updated exp 1 to 10
1028        (but does not have time-mean vs. variable split results yet)
1029    o updated global1x1/*_seaice_adj/
1030      to incorporate latest changes
1031    o enable useSingleCpuIO for mdsio vector routines
1032      (applies in particular to tapelev I/O)
1033    o removed inefficient K-loop in all active_file*control*.F
1034    
1035    checkpoint57m_post
1036    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
1037      and advect_cs (use EXCH-2 and standard cs-32 grid files).
1038    o pkg/exch2: filling of face-corner halo regions is optional
1039      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
1040    
1041    checkpoint57l_post
1042     tag before updating tutorials (pre-release-2)
1043    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
1044       for output and interpolation of input fields onto model grid)
1045    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
1046       Affects results of exp. rotating_tank ; update output.txt.
1047    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
1048          and taking the square quantity and/or using a fraction-weight field.
1049    o fix aim_diagnostics_init.F mate numbers.
1050    o add mnc output capability to diagnostics/diagstat and update
1051      our cvsignore files for the ACSII output generated
1052    
1053    checkpoint57k_post
1054    o lab_sea now uses diagnostics package and provides a suite of
1055      new EXF diagnostics output.
1056    
1057    checkpoint57j_post
1058    o exf
1059      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1060        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1061        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1062      * extended diagnostics output
1063        - now includes all EXF variables
1064        - hs, hl moved to common block
1065        - separate S/R for diagnostics, called after ctrl vector is added
1066        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1067        - EXFqnet contains true Qnet (i.e. includes qsw)
1068      * updated verif. lab_sea, global_with_exf
1069      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1070        to ensure that diagnostics sees a true EXFqnet
1071    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1072    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1073      several times with different frequencies.
1074    o mnc-ify the thsice package as requested by Daniel Enderton
1075      - the monitor--MNC output needs work
1076      - many attributes need to be added (most are currently blank)
1077    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1078      - many attributes need to be added (most are currently blank)
1079    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
1080    o add Sadourny like discretization to the 4th.O vorticity advection scheme
1081    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
1082      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
1083         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
1084    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
1085     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
1086    
1087    checkpoint57i_post
1088    o Diagnostics package was changed: diagnostic allocation is now deactivated
1089      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1090    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1091      add 1rst Order upwind vertical Shear.
1092    o add a quick fix for A/B checkpointing in OFFLINE mode
1093    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1094      end-run around the C/Fortran linking horror in eesup/src/timers.F
1095    o added pkg/runclock: allows user to terminate run based on wall clock
1096    o added non-hydrostatic scaling parameter: nh_am2
1097    o pkg/my82: futile attempt to make results compiler-independent by adding
1098      some "_d 0", etc. no effect.
1099    o for mnc output, fill the 'T' coordinate var with myTime and create a
1100      separate 'iter' variable for iteration count
1101    o pkg/diagnostics:
1102      add new capability: output of Global/Regional & per-level statistics ;
1103      tested against monitor output (including land & thSIce) on various exp.
1104    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1105    
1106    checkpoint57h_done
1107      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1108      data.diagnostics, data.gchem, data.ptracers) is done.
1109    
1110    o pkg/diagnostics: prepare for Global/Regional statistics.
1111      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1112    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1113      and rename it: DIFFERENT_MULTIPLE
1114    
1115    checkpoint57h_post
1116    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1117    o pkg/diagnostics: change output frequency, now in seconds (instead
1118      of Nb of iterations). This requires to change data.diagnostics.
1119    checkpoint57h_pre
1120    
1121    o in mnc, let the user create the output dir if both mnc_outdir_date
1122      and mnc_outdir_num are false
1123    o add fflags() to pkg/diagnostics which allows one to specify, on a
1124      per-file basis, the file precision [default behavior is unchanged]
1125    o added diagnostics to pkg/kpp, including computation of mixed layer
1126      depth based on a temperature/density criterion
1127    o updated verification/natl_box to test the new pkg/kpp diagnostics
1128    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1129    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1130    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1131      not mnc -- this mistake was found by JMC and is now corrected
1132    
1133    checkpoint57g_post
1134    o add Adams-Bashforth 3rd Order time stepping:
1135      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1136      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1137    checkpoint57g_pre
1138    
1139    o make lambda[Theta,Salt]ClimRelax spatially varying
1140      (default remains spatially uniform constant based on tau)
1141    o added new control variables
1142      * init. uVel, vVel, etanN
1143      * lambda[Theta,Salt]ClimRelax
1144    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1145      (suggested by G. Forget)
1146    
1147    checkpoint57f_post
1148    o add parameter "baseTime" = model base time = time at iteration zero
1149      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1150      account for baseTime shift
1151    o move Coriolis arrays from PARAMS.h to GRID.h
1152    checkpoint57f_pre
1153    
1154    o mnc-ifying the seaice package
1155    o introduced an alternative length scale calculation for use in the limiting
1156      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1157    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1158    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1159      as well as grad(vort3).  Made it compatible with both approximate form
1160      for the cubed sphere and full form of these gradients.  Added flag
1161      useFullLeith to select between approximate and full form.  
1162    o add "d0" in getcon.F to reduce differences between compilers/platforms
1163      update output.txt of exp. fizhi-gridalt-hs
1164    o change port_rand funtion to allow to set the seed.
1165    o fix obscure MNC bug involving conversion between reals and integers
1166      - it caused no problems with certain (eg. gcc, ifc) compilers but the
1167        new version is now more standards-compliant
1168    o adjoint-related modifications
1169      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
1170      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
1171      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
1172    
1173    checkpoint57e_post
1174    o Adding eddy stress controls a la Ferreira et al.
1175    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
1176    
1177    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
1178      update output.txt of exp. fizhi-gridalt-hs
1179    o add more "Z" dimensions and associated coordinate vars to MNC
1180    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
1181    o parameter calendarDumps: when set, approximate months (30-31 days) and years
1182      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
1183      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
1184      months and years.  Requires pkg/cal.
1185    o diagnostics: add pickup functionality
1186      - off by default for backwards compatibility
1187      - current version only uses MDSIO -- MNC will be added
1188    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
1189    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
1190    
1191    checkpoint57d_post
1192    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1193    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1194      output from the diagnostics package
1195    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1196    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1197      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1198    o add coordinate variables to the MNC output from the diagnostics package
1199    o change MNC-flags default value: true when useMNC=TRUE
1200    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1201      the ability (off by default) to read the grid information using MNC
1202    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1203    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1204    o do snap-shot diagnostics at the middle of the time-interval (instead of
1205      at the end).
1206    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1207      new test for AIM with thSIce + slab-ocean
1208    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1209    o move state variable diagnostics to the beginning of the time step ;
1210      (note: still needs some work specially for snap-shot diagnostics)
1211      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1212    
1213    checkpoint57c_post
1214    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1215    o generate new output.txt files on faulks with g77 & the new -ieee option
1216    checkpoint57c_pre
1217    
1218    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1219      update output.txt of exp. global_ocean.90x40x15
1220    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1221      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1222    o add saltFlux(+File) forcing capability with periodicExternalForcing
1223    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1224    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1225    o improvements for the MNC output from DIAGNOSTICS:
1226      - correct handling of the unlimitied dimension
1227      - all dims now have associated coordinate variables
1228      - variables located at U, V, and Corner ("Z") points are now written
1229        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1230        *all* data points are output
1231    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1232    o added pkg/seaice/seaice_monitor.F
1233    o mdsio_readfield.F can now read files visible only to master MPI process.
1234    o pkg/seaice: some test code for ice-modified ocean stress
1235    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1236      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1237      spurious negative numbers for precipitation and humidity.  Will cause
1238      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1239    o pkg/ctrl/
1240      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1241        May be enabled via doPackDiag
1242      *  introduce z-scaling of
1243         + gradient (doZscalePack) and
1244         + control (doZscaleUnpack)
1245    o pkg/mdsio/
1246      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1247      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1248    
1249    checkpoint57b_post
1250    o simplify options in diagnostics_fill arguments (remove weird combinations)
1251    o fix MNC coordinate variables so that they now contain per-face index
1252      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1253      general, EXCH2 grids are only aligned to a "local" coordinate system
1254    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1255    o Implement instantaneous output within pkg diagnostics:
1256      setting a negative frequency in data.diagnostics produces
1257     "snap-shot" output (as opposed to time-average if freq > 0)
1258    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1259      NOTE: change ptracer diagnostics name: use 2 characters to work with
1260            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1261    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1262      becomes the coordinate variable for the 'T' dimension
1263    o add CF-style coordinate variables to MNC
1264      - just a first cut:  numbers are meaningless on the cubesphere and
1265        missing along the T axis but otherwise it works!
1266    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
1267    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
1268    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
1269      this is based directly on what the model compute, so that the content of
1270      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
1271    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
1272    o clean up build options files for SunOS, in particular
1273      - remove -traditional from xmakedepend
1274      - change -xarch=v9 to -xarch=native for f77
1275      - restore use of make (not gmake)
1276      - add CC=gcc if using g77
1277    o changes per discussion of AM, JMC, & EH3 today:
1278      - move redundant "grid" variables out of "state" -- in preparation of
1279        creating proper CF-style coordinate variables and in recognition
1280        that any/all grid variables can be easily copied (eg. w/NCO) from
1281        the grid files into any of the other NetCDF files
1282      - *always* output grid variables with MDSIO (this will eventually be
1283        changed)
1284      - output MNC grid file if useMNC is true
1285    o every instance of _END_MASTER() has been found and replaced with
1286      _END_MASTER( myThid ) in order to satisfy certain picky Sun
1287      preprocessors
1288    o re-arrange diagnostics pkg initialisation:
1289     - allow each package to extend the available diagnostics list
1290     - add some checking and fix small problems (multi-threaded, ...)
1291     - new S/R diagnostics_fill (replace fill_diagnostics):
1292       look through the short list of active diag. (instead of the long list)
1293       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
1294    
1295    checkpoint57a_post
1296    o this set of changes restores TAMC compatibility
1297      tested for global_ocean.90x40x15 adjoint on trough
1298      (what a pain)
1299    
1300    checkpoint57a_pre
1301    o some modifs in tools/build_options for sunos
1302    o call ctrl_pack for ctrl at end for optimcycle=0
1303    
1304    checkpoint57
1305    o add horizontal bi-harmonic viscosity for vertical velocity
1306      - new parameter viscA4W (defaults to viscA4)
1307      - affects only non-hydrostatic code
1308      - to be done: no-slip lateral boundary conditions
1309    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1310    o implement Implicit Vertical advection for pTracers
1311    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1312      (implemented also for implicit vertical diffusion & advection)
1313    o OBCS: extend application of tracer open boundary conditions
1314      to a strip beyond the boundary of width Olx/Oly
1315    o add call monitor to TAF set of required calls (flow directives)
1316      and include in natl_box_adjoint
1317    o untangle a few ifdefs related to cost, ctrl, autodiff
1318      untangel a few ALLOW_ECCO_OPTIMIZATION
1319    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1320      (theta2, salt2 in ecco_cost_weights)
1321    
1322    checkpoint56c_post
1323    o OBCS as control variables
1324      - update ctrl_ad_diff.list, obcs_ad_diff.list
1325      - remove balance of obcs controls from default
1326      - fix index bug nobcs in ctrl_init
1327      - fix dummy fields filen in ctrl_pack
1328      - add dummy weights for obcs
1329    o lsopt: comment out fort.94 output
1330    o optim:
1331      - remove unnecessary header files
1332      - adjusted namelists
1333      - add xerbla.F to Makefile
1334    o exf:
1335      - multiple modifications of exf_check_range
1336      - unit change in exf_init_runoff from [m/year] to [m/s]
1337    o mdsio:
1338      - i/o-vector change debugLevel from debLevA to debLevB
1339    
1340    checkpoint56b_post
1341    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1342      is called from DO_THE_MODEL_IO
1343      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1344      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1345      - clean up PTRACERS_WRITE_TIMEAVE a little
1346    o add another verification experiment that tests both the cfc-pkg and
1347      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1348      reactive tendencies treated inline with regular timestepping
1349    o testreport previously did a lousy job of comparing small numbers, so
1350      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1351      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1352      testreport.
1353    o ptracers_monitor: bug fix for MPI
1354    
1355    checkpoint56a_post
1356    o GCHEM: finish reorganizating the package
1357      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1358        (introduces another 3D-array for each passive tracer, but only if
1359        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1360        gchemTendency is not needed because the timestep is done separately)
1361      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1362      - GCHEM is now---more or less cleanly---separate from PTRACERS
1363      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1364        so clear to me how that should be done in a general way.
1365    o CFC: improve formatting of output in CFC_ATMOS
1366    o PTRACERS:
1367      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1368        that ALL experiments with ptracers enable can be checked. This makes
1369        GCHEM_MONITOR obsolete.
1370      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1371        monitorFreq
1372      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1373    o add PTRACERS (PTR0[1-5]) to testreport output
1374    o exf_check_range:
1375      * default changed to .TRUE.
1376      * will check values for niter0 if debLevA, every timestep if debLevB
1377      * STOP in exf_check_range if 'out of range'
1378      * range chosen generous to allow for potential extema
1379      TBD: a version with stricter range
1380           permitted range would be runtime parameters
1381  o GMredi:  o GMredi:
1382    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1383    - 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 1386  o GCHEM:

1388    - introduced a useGCHEM runtime flag and applied it everywhere.    - introduced a useGCHEM runtime flag and applied it everywhere.
1389      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1390        this flag is now only visible within GCHEM-pkg routines.
1391      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1392        be replaced by a 3D array that is computed before thermodynamics; for
1393        this, the tracer ID iTracer had to be included into the parameter list
1394        of ptracers_forcing
1395      - set up forward_step to call gchem_forcing, that will replace
1396        gchem_forcing_int in ptracers_forcing
1397      - cleaning up
1398  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
