5      ==============================      ==============================
6    
7    o pkg/kpp: added saltplume diagnostics
8    o pkg/obcs and pkg/seaice:
9      - do not set uice and vice to zero when OB*icefile are unspecified
10      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
11      - moved seaice tracer obcs after call to seaice_growth
12    o pkg/salt_plume: added various options for salt plume depth
13      criterion and for vertical distribution of the salt
14    
15    checkpoint59l
16    o pkg/ptracers: new version of ptracers pickup:
17      read meta file and write only fields which are needed to restart.
18      ( same logic as main pickup file ; also using pickupStrictlyMatch )
19    o pkg/seaice:
20      - add timescale for melting due to warm mixed layer as a means of
21        setting SEAICE_availHeatFrac more conveniently
22      - add a CPP-flag/runtime parameter check for flooding algorithm
23      - reformulated availHeat in seaice_growth.F to be independent of AREA
24    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
25      unit changes
26    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
27    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
28      SX vector computer.
29    o pkg/seaice:
30      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
31        seaice forcing fields can now be read only through pkg/exf
32      - removed some unused halos
33    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
34    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
35      or U/VICE from U/VWIND before computing U/VSTRESS
36    
37    checkpoint59k
38    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
39      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
40    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
41      all experiments pass when compile with un-initialised var. checking option.
42    o added pkg/salt_plume
43    o script to test restart (for now, in MITgcm_contrib/jmc_script)
44    o pkg/seaice: new read/write pickup version.
45      read meta file and write only fields which are needed to restart.
46      ( same logic as main pickup file ; also using pickupStrictlyMatch )
47    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
48    o lab_sea.hb87: modify the domain & update output.hb87.txt :
49      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
50      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
51      process. Fixed here by closing the domain at the Northern boundary.
52    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
53    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
54      a set of consecutive levels in/from a 3-D array.
55    o pkg/ptracers:
56      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
57      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
58    
59    checkpoint59j
60    o in pkgs: dic, obcs, offline, rbcs:
61      standard way to compute coeff. for time interpolation between 2 time reccords
62      which retains full precision (& make results less dependent on compiler).
63      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
64    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
65      packages instead of reading ice cover and wind speed separately
66    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
67     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
68      to allow to compile customized code before the update)
69    o cleaning-up:
70      - fix CPP instruction syntax in pkg/obcs
71      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
72        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
73      - fix some threads issue in IO parts.
74    o pkg/dic:
75      - add tons of "_d 0" (--> much better testreports !)
76       and then update outputs of tutorial_global_oce_biogeo
77    o pkg/mom_fluxform:
78      add a special version of momentum advection intended to conserve momentum
79      next to a bathymetry step or a coastline edge. (default = off = #undef)
80    o new read/write pickup version:
81      - for now, only implemented for main (mdsio) pickup file.
82      - write out only what is needed to restart; merge pickup_nh , pickup_ph
83        and main pickup together.
84      - read meta file; read only what is needed to restart; stop if a field
85        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
86        if it make sense (even if the restart is not perfect).
87      - if no meta file, assume that pickup to read corresponds exactly to
88        a pickup that would currently be written.
89      - read pickup written in the old format (until checkpoint59i) if it
90        recognizes an old meta file (no field-list).
91      - add a meta file in exp. which starts from a pickup: 2 cases:
92        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
93         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
94        b) a meta file describing the content of the associated pickup file
95         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
96    o pkg/mdsio & pkg/rw:
97      - new routine to read a meta file ; new set of routine to read
98        Multiple-fields file (with meta file).
99    o added open boundary conditions capability for seaice
100        HSNOW, HSALT, UICE, and VICE
101    
102    checkpoint59i
103    o adjoint:
104      * fix multiDimAdvection adjoint
105        (partial recomputation problem by TAF for fVerT(:,:,kDown)
106        and comlev1 size definition (maxpass vs. max. number of tracers)
107      * verification/global_ocean.90x45x15 adjoint now tests
108        NLFS and multiDimAdvection using DST3 (=30)
109      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
110    o pkg/kpp: add "_d 0" to real constant (if missing);
111      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
112      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
113    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
114      for internal parameters related to restart process (formerly from PARAMS.h)
115      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
116    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
117      as argument. (only atm2d & obcs write_pickup have not yet been updated)
118    o pkg/monitor:
119      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
120      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
121      - account for deep Atmosphere factor and density factor (anelastic)
122    o added open boundary conditions capability for seaice HEFF and AREA
123    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
124      thermodynamics
125      - requires a little reorganization, which affects the testreport results
126        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
127        so that now the conservative form is tested
128      - add a few comments
129    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
130    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
131    o add new diagnostics to seaice: advective, diffusive fluxes (only for
132      multidim-advection, for scheme 2 they are not filled) and transports,
133      thermodynamic growth rates
134    o change units of EmPmR (inside the code, + within coupling interface)
135      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
136      Affects results @ truncation level (cg2d match) and update output of
137       experiments: lab_sea(6), global_ocean.90x40x15(10),
138      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
139      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
140      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
141      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
142    
143    checkpoint59h
144    o pkg/exf:
145      - improve vectorization by moving if-statement out of loops in
146        exf_mapfields, exf_radiation
147      - exf_bulkformulae.F: introduce 2D fields and vectorize code
148    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
149    o testreport:
150      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
151        monitor & update offline_exf_seaice exp. output.
152      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
153    o pkg/seaice:
154      - bug fix in the evp solver: boundary conditions were affected be
155        masking of zMax/zMin (changes results)
156      - minor bug fix in boundary conditions in seaice_calc_strainrates
157        (changes results for no_slip)
158      - seaice_lsr.F: make interpolation of eta dependent on boundaries
159      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
160      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
161        stress formulation and no-slip boundary conditions
162    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
163      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
164    o pkg/seaice: a first HSALT time stepping equation has been checked in
165    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
166      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
167      without requiring DO-IF statements
168    o pkg/thsice:
169      use continuous power-law function for partition of energy between lateral
170      melting/freezing and thinning/thickening ; old code using step function
171      still available with #undef THSICE_FRACEN_POWERLAW
172      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
173    o testreport: change AD testing : check against results/output_adm.txt
174      using same scripts as for forward test.
175    
176    checkpoint59g
177    o adjoint testing: in preparation for changing testreport:
178      - output format: cost and grad written on separated lines
179      - ad output results in directory "results" (instead of "results_ad")
180    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
181    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
182    o pkg/ecco: allow user defined cost function contributions
183    o testreport:
184      Allow to choose (per experiment) the list of tested output variables
185       and the main variable (used to issue a pass/FAIL ) ;
186      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
187      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
188      Also modify printing of summary:
189       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
190       b) echo the list of tested variables in the individual summary.txt of
191          each experiment.
192    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
193      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
194      (but still depend on the tile decompostion of the domain).
195    o pkg/seaice: change a discretization detail to make the B-grid code
196      "more symmetric". This change is likely to remove all "ridges/leads" that
197      where quasi-aligned with the grid in B-grid solutions. It may also be
198      the solution to the stress coupling issues with the B-grid.
199    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
200      remove .cvsignore from input dir. (since testreport no longer run here).
201    o pkg/thsice:
202     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
203     - fix reshaping of sea-ice just after advection:
204       melt all the ice only if ice-volume is too small.
205     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
206       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
207     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
208    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
209      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
210    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
211      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
212      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
213      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
214      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
215      -> update output.txt
216    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
217     this affects truncation error: -> update output.txt of exp:
218      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
219      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
220    
221    checkpoint59f
222    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
223    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
224      a bounded range (in forward mode)
225    o pkg/ecco, ctrl, autodiff and mom_common:
226     internal parameter controls, completements of implementations
227    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
228    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
229      (not seem any difference in testing results).
230    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
231       at face corners.
232    o pkg/generic_advdiff:
233     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
234      loop range indices for computing vertical advection tendency
235      and do the calculation in the interior only (no overlap) ;
236      for now, only implemented for SOM advection (to save CPU time).
237     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
238    o exch2 adjoint
239      First set of changes:
240      - add exch2 hand-written adjoint templates
241      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
242        This will require cleanup in pkg/autodiff/*.F
243        (changed routines currently kept separate in verif. code/)
244      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
245        that used to hide exch2 or cubed-sphere specific code
246        (commented via 'cph-exch2')
247    o pkg/seaice
248      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
249    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
250       output of global_ocean.cs32x15.thsice .
251    
252    checkpoint59e
253    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
254      for B-grid vector (not yet tested) and C-grid vector (<- only used
255      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
256    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
257      (#ifdef ALLOW_SALT_PLUME)
258    o gather_2d/scatter_2d: removed halo regions
259    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
260      scheme and the corresponding test case (under front_relax dir). For now,
261      only available with Skew-flux form and not yet tested in realistic set-up.
262      adjoint: store directives updated, but gradient checks deteriorated,
263      so maybe GM/Redi adjoint is now broken.
264    o seaice adjoint
265      * add AREA, HEFF, HSNOW as control variable
266        (should not change lab_sea results)
267      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
268    o pkg/seaice:
269      * added computation of saltFlux in seaice_growth;
270        For time being, sea ice salinity is assumed constant
271        contribution of snow flooding to freshening of sea ice is neglected.
272        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
273        defaults to 0.0 in order to maintain backward compatibility.
274        Typical values for SEAICE_salinity are 4 to 10 g/kg.
275      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
276      * added SEAICE_availHeatFrac, which specifies fraction of surface level
277        heat content used to melt or grow ice
278      * commented out cap of HICE: it helps keep ice thinner
279      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
280      * applied OBCS T/S mask to HEFFM sea ice mask
281    
282    checkpoint59d
283    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
284     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
285     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
286    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
287     and change default value of parameter "GM_Small_Number";
288     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
289       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
290       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
291    o pkg/ecco: cost function when applying pkg/smooth to controls
292    o pkg/ctrl: add forcingPrecond run time parameter
293    o pkg/seaice:
294     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
295     - fix bug in metric terms of u-equation in LSR solver (implicit part),
296       changes verification/lab_sea
297     - rearrange implicit part of u-equation in LSR solver to make it easier to
298       read, understand, and debug. This causes changes at the truncation level.
299     - fix (serious) bug in the boundary conditions (sign error in the implicit
300       part) of the LSR solver. Changes all LSR results.
301     - fixed problem with HSNOW initialization to avoid thick snow when AREA
302       is initilized with small values - does not change lab_sea results.
303     - added HsnowFile initialization capability
304    o pkg/smooth: addition to model/src and pkg/ctrl so allow
305     initialization of pkg/smooth and application to control vector
306    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
307    o dependencies: pkg/profiles requires pkg/cal
308    o pkg/profiles:
309     - added option ALLOW_PROFILES_GENERICGRID
310         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
311         that interpolation information (grid points and coefficients) is provided
312         within the netcdf input files.
313         -> sample matlab scripts can be found in MITgcm_contrib/gael
314         that allow you to prepare netcdf input files.
315     - also modified: cleaner include statements, cleaner error print statements,
316       cleaner stops when error, and more tests of the netcdf input files consistency.
317    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
318    o pkg/seaice:
319     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
320       requires a new routine: seaice_diagnostics_fill.F
321     - make sure that seaice does not move if not forced (pressure replacement
322       method, Hibler and Ip, 1995), changes results
323     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
324     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
325       It is turned off by default (=-1.), because it changes the results.
326     - make it possible to read AREA from a file, too.
327    
328    checkpoint59c
329    o add S/R and diagnostics for oceanic mixed-layer depth
330    o move GMRedi call after all vertical mixing schemes (including KPP)
331    o pkg/thsice:
332     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
333      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
334    o pkg/obcs:
335     - bug fix for balance code
336    o pkg/seaice:
337      - allow values of SEAICE_elasticParm > 1
338      - add new parameter SEAICE_evpTauRelax as an alternative
339        to SEAICE_elasticParm
340      - make lsr boundary conditions free slip (by default), changes result
341      - add code for no slip boundary conditions for lsr
342      - set minimum of zeta to zero (and not 4e8) (changes results)
343      - add a cap on AREA after advecting AREA if seaice_growth is not called
344    o change calculation of Visbeck K:
345      - no longer depend on tapering scheme; instead, compute slope (limited
346        by GM_maxSlope). this is equivalent to what was comuted before with
347        clipping or linear tappering.
348      - fix vertical averaging (wrong by 1/2 level)
349      - leave the old version (but will not be maintained) within
350        #ifdef OLD_VISBECK_CALC / #endif
351      - update output of exp. ideal_2D_oce
352    o change error catch in calc_r_star to improve vectorization
353    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
354      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
355    o adjoint:
356      Re-organized adjoint checkpointing according to Matt Mazloff
357      (but with modifs/completions/cleanups)
358      Storing is now bundled into large arrays to optimized I/O
359      (and second step in cleanup of the_main_loop)
360    
361    checkpoint59b
362    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
363      - export/import (between ocean & coupler) fields needed for ocean DIC.
364    o pkg/seaice:
365      - get rid of three more exchanges seaice_calc_viscosities (required
366        different loop boundaries in seaice_lsr and seaice_ocean_stress)
367      - bug fix in seaice_ocean_stress (update of lab_sea required)
368      - reduce loop boundaries to necessary minimum also in seaice_evp
369      - go back to the old way of computing deltaC/Z as the adjoint likes that
370        better
371    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
372      passive tracer to an Age Tracer) + update output.txt
373    o pkg/exf:
374      - implement A-grid / C-grid selection for wind-stress input files.
375      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
376      for now, in exf_bulk_largeyeager04.F only :
377      - change implementation for case where windspeed + 2. components wind-stress
378        are read-in. AND use rhoConstFresh to convert evap.
379    o pkg/seaice:
380      - use correct EXCH_UV for wind-forcing (on A-grid).
381      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
382        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
383    o pkg/exf:
384      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
385      EXF_INTERPOLATION:
386      - merge global_with_exf/code version of exf_interp_read.F
387        to the main code ;
388      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
389        reading the file ; Important: This options needs to be defined to recover
390        previous code.
391        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
392      - no longer loose real*8 precision along the way when using exf_iprec=64.
393    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
394      - change discretisation of evp-solver in order to avoid another exchange
395        (changes lab_sea) and clean up a little
396      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
397        help the adjoint (this also changes the results slightly)
398      - add a few "_d 0" where they had been missing in seaice_evp.F
399      - cleaning up: remove unused seaice_calc_rhs.F
400    o pkg/exf: some cleaning-up:
401      - change various "constants" into runtime parameters
402      - cleaned-up Large&Yeager04 routine which should eventually
403        replace exf_bulkformulae.F (changed names of S/R and CPP)
404        and merged various ALLOW_ATM_WIND options
405     only used with thsice pkg (in thsice_get_exf.F):
406      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
407        which are used when useStabilityFct_overIce=TRUE (= the default)
408      - change default values of ice & snow emissivity and scale downward LW
409        by ice & snow emissivity.
410    o pkg/thsice:
411     fix few little problems, in thsice_calc_thickn.F:
412      - growth vertically (and not laterally) if iceFrac == iceMaskMax
413      - melt only laterally if hIce < hThinIce (as the comments say)
414      and in thsice_extend.F:
415      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
416      - start to form ice as soon as the minimum ice-volume is reachable.
417     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
418      and cpl_aim+ocn
419    o pkg/kpp
420     - move computation of surface related input fields to KPP into a new
421       subroutine kpp_forcing_surf.F
422     - remove wrong (within bi,bj loops) EXCH calls.
423     - little cleaning (add argument myThid in last position, cvs header ...)
424     - for now, fix conservation problem by exchanging KPPviscAz (may not
425       be the best fix)
426    o pkg/seaice
427     - check for inconsistent evp parameter/cpp-flag combination
428     - remove leftover errIO flat for obsolete name list error handling
429    o OpenAD
430     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
431    
432    checkpoint59a
433    o pkg/seaice: some parameter clarifications and a little bit of clean up
434    o pkg/thsice: rename run-time parameters:
435       himin       -> hIceMin
436       himin0      -> hThinIce
437       hihig       -> hThickIce
438       i0          -> i0swFrac
439       transCoef   -> bMeltCoef
440       frac_energy -> fracMelting
441      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
442       with default values (for now) that do not change the results.
443      remove old version of thsice vars advection in pkg/seaice.
444    o in FFIELDS.h:
445      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
446      - make pLoad & sIceLoad always available (but still only used if
447         ATMOSPHERIC_LOADING is #define).
448    o pkg/kpp: replaced _KPP_RL with _RL
449    o bug fixes for vertical diffusivity computations when both KPP and
450        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
451        are no longer updating the vertical diffusivity array
452        (passed as argument) but are (re-) setting those arrays.
453    o pkg/seaice: fix bug in evp solver, while doing that
454      - change (improve?) discretization of stress computations for both
455        cgrid-lsr and evp solver
456      - add a new routine to compute strain rates
457      - the above changes lab_sea results
458      - add no slip conditions for evp solver (off by default), lsr-version
459        may follow
460      - fix exchange for shear at Z-points (does not change lab_sea)
461      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
462        (to force the user to pick a time step since there is not "safe" way
463        of choosing it)
464      - add principal stress diagnostics
465      - rearrange fields for evp a little to avoid having to call a: too many
466        exchanges and b: exchanges for stress trensor components which we do
467        not have.
468      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
469        of evp, complete rewrite for lsr case (latter is does not yet work
470        in all cases)
471    o pkg/kpp: add code to have mixing in shelf ice caverns
472      - add myThid to all kpp routines (long overdue)
473    
474    checkpoint59
475    o pkg/exf:
476      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
477        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
478      - move exf header files from lower_case.h to UPPER_CASE.h ;
479        add missing cvs Header & Name
480      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
481      - add namelist param. selectStressGridPosition, exf_monFreq
482      - retire many _CLIM routines, and remove data.exf_clim
483        + params moved to data.exf
484        + climsst, climsss now handled by exf_set_gen, i.e.
485          climss?period=0 refers to constant field,
486          climss?period=-12 to monthly forcing
487      - split up namelists in data.exf
488    o pkg/seaice:
489      - remove seaice_exch and seaice_exch_uv
490      - remove superfluous exchange of theta
491      - add myThid to seaice_budget_ocean/ice
492      - add new interface for atmospheric wind forcing (C-grid only)
493        + new routine
494        + two new field (taux, tauy for stress over ice)
495        + removed one global field (DAIRN) for C-grid case only
496    o pkg/thsise
497      - 2nd set of modifs for thsice adjoint in conjunction with exf
498    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
499    
500    checkpoint58y_post
501    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
502      vertical diffusivity, similar to that in MOM4; turned on using
503      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
504      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
505    o Added capability for 3D specification of background vertical diffusion
506      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
507      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
508      "data" file that contains the 3D vertical diffusivity coefficients.
509    o ice dynamics (pkg/seaice) with thsice thermodynamics:
510      - add code within pkg thsice to advect & diffuse sea-ice fields
511      similar to (and will replace) what has been added in  seaice_advdiff.F,
512      but: - conserving Mass, Heat & Salt.
513           - better when using non-linear advection scheme (not yet fully tested)
514           - can also be used in atmospheric set-up (for now, only the diffusion).
515    
516    checkpoint58x_post
517    o IO option for global-file compact format:
518      - add options when generating topology (utils/exch2/matlab-topology-generator)
519      - add I/O capability (pkg/mdsio).
520      - adapt utils/matlab/rdmds.m to read this format.
521      for now long-line format not yet supported by pkg/mdsio (& exch2).
522    o shelfice: add a few diagnostics
523    
524    checkpoint58w_post
525    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
526      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
527      (and replace horiVertRatio in NH code).
528      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
529                         and tutorial_plume_on_slope (sensitive to truncation)
530    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
531      directly to drive seaice model (C-grid only)
532    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
533     - reintroduce computation of wind from stress,
534     - compute tau (in exf_bulkformulae.F) from windstress averaged to
535       mass points to avoid tau = 0
536     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
537    o rdmnc.m: make it work with "global" files created with gluemnc
538    o rdmnc.m : some improvements in dealing with singleton dimension
539      (tested on all testreport mnc output files).
540    o genmake2: disable pkg/profiles if netcdf test fails.
541    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
542    o move call to cal_readparms up to make calendar parameters/variable available
543      to all packages
544    
545    checkpoint58v_post
546    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
547      useDynP_inEos_Zc tested.
548    o pkg/exf: changes to properly interpolate/mask/scale initial fields
549    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
550      and portions thereof.  See read_cs.txt for description and examples.
551    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
552      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
553      following the great-circle arc between those 2 points.
554    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
555      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
556    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
557     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
558     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
559     - still needs work (not working with some options ; efficiency to improve)
560       and serious testing.
561     - use this scheme for temperature & salinity in 2 advection test exp.:
562       advect_xy & advect_xz, respectively.
563    
564    checkpoint58u_post
565    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
566    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
567    o testreport: add option "-skipdir" to skip some test.
568    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
569      momentum calculation.
570    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
571    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
572      remove checkpoint.F and the_correction_step.F (no longer used);
573      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
574    o add option (linFSConserveTr) to correct for tracer source/sink due to
575      Linear Free surface
576    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
577    o pkg/thsice: fix reading mnc-pickups
578    
579    checkpoint58t_post
580    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
581    o pkg/mdsio:
582     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
583       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
584       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
585     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
586     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
587       either MDS_READ_FIELD or MDS_WRITE_FIELD )
588     - new S/R (to replace MDSWRITEMETA), which allows to write more
589       informations (variable names, time ...) to meta files.
590     - modify rdmds.m to give back the meta file content.
591    o pkg/diagnostics: change vertical interpolation to be safer, and more
592       flexible (define p-levels to interpolate to in data.diagnostics);
593      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
594       diagnostic pointer.
595    o pkg/seaice: more cleaning up of seaice_growth, added many comments
596    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
597    o fix multi-category seaice:
598     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
599       SEAICE_MULTICATEGORY
600     - fix short wave heat flux
601    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
602       and allow to use EVP solver. Change forward lab_sea: test both EVP
603       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
604    o Initial check-in of lab_sea adjoint
605      (very similar to natl_box_adjoint/code_seaice)
606      * used C-grid and EVP solver
607      * used KPP, GM/Redi
608      * uses inAdExact=.TRUE.
609      * gradient checks fail for both ADM and TLM
610        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
611        f.d. gradients actually seem more problematic than ADM, TLM gradients;
612        issue is related to forward mismatch between g77 an ifort
613    o pkg/seaice: overhaul of thermodynamics
614     - growth.F and groatb.F are replaced by new routine seaice_growth.F
615     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
616     - move a few global fields out of SEAICE.h into seaice_growth.F and
617       make them 2D (FICE/QNETO/ ...)
618     - remove FO (it is the same as QNETO)
619     - introduce a few local fields to avoid modifying external fields such
620       as atemp, etc.
621    
622    checkpoint58s_post
623    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
624      changed exf_set_gen.F so that
625        genperiod=0 means input file is one time-constant field and
626        genperiod=-12 means input file contains 12 monthly means
627    o CG2D: use pre-computed solver main-diagonal (stored in common block);
628      this affects truncation error ; generate new output file for exp. which
629      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
630        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
631        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
632        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
633        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
634        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
635    o start implementation of deep-atmosphere and anelastic formulation
636    o verification: remove 2nd copy of input files and use script "prepare_run"
637      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
638    o mom_common/vecinv/fluxform: fix a few initialisation isssues
639    o profiles: fix for multithreaded case
640    
641    o diagnostics: rename few diags:
642      s/'PRESSURE'/'RCENTER '/g
643      s/'TICE    '/'oceFreez'/g
644      s/'TAUX    '/'oceTAUX '/g
645      s/'TAUY    '/'oceTAUY '/g
646      s/'SWFLUX  '/'oceQsw  '/g
647      s/DIFx/DFxE/g
648      s/DIFy/DFyE/g
649      and add few ocean-forcing diagnostics:
650      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
651    o modifications to pkg/seaice/growth.F and budget.F, which change results of
652      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
653      as actual snow thickness.  It now refers everywhere to effective snow
654      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
655    
656    checkpoint58r_post
657    o modifications to pkg/seaice/growth.F, which change results of
658      lab_sea experiment: fixes pertain to melting snow over open water, to
659      masking EVAP under sea ice, and to using the correct AREA variable for
660      computations of EVAP, PRECIP, HSNOW, and GHEFF
661    o add ability to read bathy, salt, and theta using MNC (off by def)
662    o add flooding algorithm and advection of HSNOW for pkg/seaice;
663      both are turned off by default and do no change any results
664    o seaice advection with pkg/thsice: a step toward the use of non-linear
665      advection scheme, but #ifdef or commented out for now (requires more EXCH).
666    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
667      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
668      in natl_box (affects results @ truncation level: update output.txt)
669    o multi-threading and IO:
670      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
671      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
672        (needed to work with SingleCpuIO): tested in all verif. exp.
673    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
674      affects the results (but none of the verification test uses this scheme).
675    o Adding some pkg/diagnostics capability to pkg/seaice
676      (will certainly be subject to changes)
677    o ctrl: adding new control variables:
678      lwflux, lwdown, evap, snowprecip, apressure, runoff
679    
680    checkpoint58q_post
681    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
682      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
683      high_res_cube configuration by 4% on Columbia.
684    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
685      add (in global_with_exf/code) a version of EXF_INTERP_READ without
686      dynamical allocation (seems to work in multi-threaded).
687    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
688      single CPU io) so that TAF does not have to see EESUPPORT.h
689    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
690    
691    checkpoint58p_post
692    o obcs: stop if obcs is used with useCDscheme = .true.
693    o shelfice:
694     - fix a sign error so that no slip at shelfice interface works
695     - remove stop for combination non-hydrostatic code and shelfice. That does
696       not mean, that the results are correct, but at least they are numerically
697       stable
698    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
699    o added adjoint exch routined for all exch*3d* routines
700      and updated flow directives
701    
702    checkpoint58o_post
703    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
704      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
705    o change controling S/R for writing pickup file (new S/R do_write_pickup)
706      and clean-up reading/writing of pickup files.
707    o fix local version of read/write pickup (NH part) in rotating_tank/code
708    o simplify EXCH interface:
709     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
710     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
711    o added the regrid package
712    o shelfice:
713     - add a simple boundary layer scheme to reduce noise
714     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
715    
716    checkpoint58n_post
717    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
718       local variable (not in common block).
719    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
720      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
721      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
722        to work with SingleCpuIO.
723    o add "_d 0" to real constant of pkg/cfc subroutines ;
724       update exp. cfc_exemple & tutorial_cfc_offline output files.
725    o multi-threading and IO:
726      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
727        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
728      - barrier before and after reading.
729      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
730      - avoid using MDS_WRITELOCAL for LAND pkg output.
731      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
732        common-block variables ; Allows multi-threading with master-thread IO.
733    o change default MAX_NO_THREADS from 32 to 4 ;
734      and stop cleanly when MAX_NO_THREADS is too small.
735    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
736    
737    checkpoint58m_post
738    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
739       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
740    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
741       keep global_ocean.90x40x15 (for AD testing) with former secondary test
742       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
743    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
744        add MITgcm_tutorials (= code + all the tutorials)
745    o ecco, option to compute cost for total ssh (mean+anom)
746    o consistent with addition of ptracer and ssh in pkg/profiles
747    o profiles: adding ptracer and ssh
748    o testreport: change multi-test output-file name
749      (from output.txt.{name} to output.{name}.txt)
750    o profiles: now ok for mutli-tiles case
751    o seaice: add 4 parameters for different advection schemes for area,
752      (effective) seaice thickness, enthalphy, and snow height. Their default
753      is the standard parameter SEAICEadvScheme
754    o calc_gw:
755     - add cosFacU in zonal viscous flux (harmonic.visc.).
756     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
757       of tutorial_plume_on_slope.
758    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
759    o calc_gw: true flux-form, account for horizontal grid spacing.
760      update rotating_tank results, but not plume_on_slope (affected at
761      truncation level, 11 digits).
762    
763    checkpoint58l_post
764    o calc_gw:
765     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
766     - remove side-drag for now (need to fix it); update plume_on_slope results.
767     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
768    o commit code to make SST/SSS weights spatially variable
769      (based on either variable in-situ or variable initial T/S weights)
770    o pkg/ecco:
771      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
772        now based on horizontally varying weights wthetaLev, wsaltLev
773      * cost_averagesflags now returns year indices in addition to day, month
774      * sflux balance is performed on annual basis
775        (sflxumm, sfluxmm2, bal_sfluxmm)
776      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
777        including separate counting and multipliers
778    o pkg/rbcs
779      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
780    
781    checkpoint58k_post
782    o testreport:
783     - always build in dir. "build" (if not there, mkdir build instead of building
784       & running in input)
785     - run in dir run (if it exists), in build otherwise.
786     - call prepare_run (if input/prepare_run exists)
787     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
788    o pkg/exf modifications to interpolation and rotation routines for more
789       reasonable treatment of North Pole singularity: for tracers North Pole
790       value is set to northernmost zonal-mean value, for zonal velocity it is
791       set to zero, and for meridional velocity it is set to northernmost value.
792    o pkg/exf/exf_check_range.F
793     - add tile index to diagnostics and move stop statement to the very
794       end of the routine.
795    o pkg/diagnostics: (diagnostics_main_init.F)
796      define title of isomorphic variables according to the current config.
797    o pkg/thsice with pkg/seaice dynamics:
798    - fix domain of computation (interior only, required for exf) and do exchanges
799    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
800    o towards a standard way of dealing with multi-threading in MONITOR
801      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
802    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
803       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
804    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
805    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
806    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
807       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
808    o tracer advection:
809     - clean-up and simplify calc_common_factors.F
810     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
811       advection subroutine (but still not used within DST advection S/R)
812    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
813    
814    checkpoint58j_post
815    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
816      from file (collects calls previously in FORWARD_STEP)
817    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
818    o adjoint store dir. adjusted accordingly
819    o genmake2
820      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
821    
822    checkpoint58i_post
823    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
824      on wind stress (SEAICEstressFactor defaults to 1.)
825    o Total number of Timers is finite (<=40): comment out 2 non-essential one
826      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
827    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
828      on CS-grid: no longer loosing mass.
829    o exf & curvilinear-grid: no longer modify longitude xC & xG.
830    o pkg/ggl90: fix sloppy output and fix a bug
831    o pkg/seaice: added SEAICEuseEVPpickup parameter
832      - Set to false in order to start EVP solver with
833        non-EVP pickup files when using SEAICEuseEVP
834      - fix sign error in diffusion in seaice_calc_rhs
835    
836    checkpoint58h_post
837    * Modifications for bottom topography control
838      o replace hFacC by _hFacC at various places
839      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
840      o add non-self-adjoint cg2d_nsa
841      o update autodiff support routines
842      o re-initialise hfac after ctrl_depth_ini
843      o works for 5x5 box, doesnt work for global_ocean.90x40x15
844    * Adding verification for 5x5 box (4-layer) bottom topography control
845    
846    checkpoint58g_post
847    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
848       used for mean seasonal cycle, mean diurnal cycle); add an example
849       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
850    o pkg/ggl90:
851      - add parameter (minimum surface kinetic energy)
852      - fix bug (avoiding division by zero)
853    o couple pkg/thsice to pkg/seaice:
854      - modify advection in seaice to accomodate new scalar fields to be advected
855      - only muliDimAdection scheme work with seaice/thsice
856      - mapping of thsice-variables to seaice-variables, back and forth
857      - does not break the verification experiments, but does not give the
858        desired results either
859    o pkg/seaice
860      - make (default) second order advection a bit less confusing?
861    
862    checkpoint58f_post
863    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
864      to pkg/seaice):
865      - new routines thsice_map_exf and thsice_get_exf provide the interface
866      - add an additional formal parameter to thsice_solve4temp
867    o pkg/exf:
868      - add new fields wspeed, snowprecip (to be able to couple to thsice)
869      - correct Stefan-Boltzmann constant
870      - new parameter for longwave surface emittance
871      - separate some stuff from exf_bulkformulae into new routines  
872        exf_radiation, exf_wind
873      - add new parameters and constants: longwave emissivity for ocean, ice
874        and snow, evaporation parameters over ice
875      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
876        either wind from stress or stress from wind
877    o pkg/thSIce:
878    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
879    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
880       and THSICE_CALC_THICKN
881    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
882    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
883      to make debugging easier.
884    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
885    o pkg/bulk_force:
886      - clean-up comments and parameters ;
887      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
888    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
889      generate new output for test-experiment: aim.5l_cs.thSI
890    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
891      testreport accordingly
892    
893    checkpoint58e_post
894    o SEAICE_CGRID adjoint done
895    o R_STAR adjoint implemented.
896      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
897      * need to sort out init. of h0facc, etc.
898    o Make pkg/profile fully independent of ecco,cost, etc. stuff
899      to be able to use it in pure forward.
900    
901    checkpoint58d_post
902    o upgrade simple test-experiment to tutorial example:
903     step.1: duplicate the experiment and (step.2) will remove the old copy.
904      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
905      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
906      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
907      tutorial_global_oce_biogeo    <- copy of dic_example
908      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
909      tutorial_plume_on_slope       <- copy of plume_on_slope
910      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
911      tutorial_global_oce_optim     <- empty for now (David ?)
912      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
913     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
914    o correct a sign problem in cost_scat.F
915    o obcs and ptracers: fix boundary conditions for advections schemes
916      with larger stencil
917    o thsice adjoint: start
918    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
919      completeness
920    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
921      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
922    o ptracers adjoint:
923      * avoid extensive recomputatations
924      * fix missing re-init. of gptr (missed by TAF)
925    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
926      me to turn off the excessive output to STDOUT that this package produces
927    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
928      and add those terms in Vector-Invariant formulation.
929    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
930      if the control period (xx_hfluxperiod etc) is 0
931    o in profiles pkg, clean routines and fix details
932    o in ecco pkg, reading ssh data:
933      fix problem in case the model does not start at iter0=0
934    o fix mnc-pickup/restart for ptracers
935    o new package prifiles:
936      code to compute profile-based cost by Gael Forget
937      (modifs in ecco, ctrl, autodiff)
938    o Benign bug fix in initialization (spotted by M. Mazloff) of
939      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
940    
941    checkpoint58c_post
942    o adjoint: finish NLFS adjoint and provide reference output in
943      verification/global_ocean.90x40x15/results_ad_nlfs
944    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
945      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
946      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
947      with SEAICE_CGRID defined.
948    o move calendarDumps from "data" to "data.cal" and clean-up the code
949      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
950    o add useEXF & useCAL flags (for now, set in hard-coded way)
951    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
952      (were missing in NH mode, and wrong in quasihydrostatic mode).
953      waiting for Chris updated version of calc_gw to add those CALLs.
954    o fix bug in quasihydrostatic S/R ;
955      add a test for this option: global_ocean.90x40x15.qshyd
956    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
957      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
958    o add on/off flag useOffLine for package OFFLINE
959    o seaice:
960      - modify advection so that it works also on the C-grid
961      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
962        problem in multi-tile runs with C-grid
963      - add flags for clipping ice velocities and/or masking solver forcing
964      - fix drag (ocean on ice) formulation and a bug that caused noise in the
965        C-grid solver
966      - added a few comments to seaice_diffusion.F
967      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
968        are now exclusive)
969      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
970        required re-ordering the code a little:
971       + make DAIRN global variable (defined in SEAICE)
972       + move computation of the viscosities eta and zeta into a new separate
973         routine (because I need to recompute them in seaice_ocean_stress.F)
974    
975    checkpoint58b_post
976    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
977      update output.txt of exp. aim.5l_cs.thSI
978    o various mnc cleanups and improvements:
979      + shrink lookup tables by factor of ~4
980      + better error reporting when running out of lookup space
981      + able to handle longer path/file names (up to 500 chars)
982    o adjoint:
983      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
984      - TBD: "hidden" mom_vecinv recomp. in dynamics
985    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
986     (allow to differentiate between forcing components using new integer flags:
987      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
988     and add new flag to put Dissipation tendency out of Adams-Bashforth.
989    o ecco
990      - enable trend removal from SSH anomaly obs.
991    o adjoint
992      - a fix for PmEpR when #undef EXACT_CONSERV
993      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
994      - try to fix "hidden" recomp. in forward_step for NLFS
995        (NLFS seems broken sometimes after I checked it in)
996    o seaice:
997     - add c-grid version of the dynamic solver:
998       + three new routines that are the c-grid substitute lsr, dynsolver
999         and ostres
1000       + put a few fields that were local to dynsolver into global common
1001         blocks, so that I can move the computation of stresses etc into
1002         seaice_lsr (saves coding but may break the adjoint).
1003     - replace more hardwired parameters by runtime parameters
1004     - add ice masks that mask the rhs of the implicit solvers where there
1005       is no ice (commented out in seaice_dynsolver, because i am not sure
1006       if this works properly), eventually this should replace the clipping
1007       of ice velocities in seaice_dynsolver to +/-40cm/s.
1008    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1009      include it only where its needed
1010    o move balancing of fluxes before the call of external_forcing_surf
1011    o seaice:
1012      - correct units of turning angles (now they are really in degrees)
1013      - move computation of GWATX/Y out of main routine into dynsolver
1014      - initialize GWATX/Y in seaice_init
1015    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1016      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1017    o seaice: add runtime flags for turning angles (default to zero)
1018    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1019      and trend from exf forcing and ctrl control adjustments
1020    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1021      (since checkpoint57x_post)
1022    o change the default rotation period to 86164.s = the Earth rotation
1023    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1024      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1025    o seaice advection: add code for choosing between the default (2nd order
1026      central differences) and multiDim advection schemes provided by
1027      pkg/generic_advdiff
1028    o seaice:
1029      - removed all references to SEAICE_GRID.h fields from
1030        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1031        (cubed-sphere configuration will change a little)
1032      - grid computations in seaice_init are obsolete now.
1033      - cleaned up code a little so that is easier to read (hopefully).
1034      - added new (better?) discretizations of default advection and diffusion
1035        (turn on with SEAICEuseFluxForm)
1036      - replace 1 in 3d global fields by kSurface in growth.F
1037      
1038    checkpoint58a_post
1039    o seaice:
1040      - bug fix in advect.F
1041    o shelfice:
1042      - separate shelfice load anomaly from pload (breaks with time
1043        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1044        Its default is 0., but it may be computed more cleverly from (unknown)
1045        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1046        done offline. A good approximation of the pressure load anomaly is
1047        necessary to avoid large initial adjustment processes underneath
1048        deep-reaching shelfice.
1049      - small fix in ISOMIP shelfice_thermodynamics
1050      - add more sophisticated thermodynamics of Hellmer (1989), this is
1051        now the default
1052      - give a few constants more intuitive names
1053    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1054      if bulk formulae are used in long integration (especially EmPmR). Turn
1055      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1056      if balancePrintMean, the imbalance that is substracted is printed to
1057      STDOUT.
1058    o fix bug (typo) in obcs_apply_eta.F
1059    o add a new package shelfice which enables us to model the circulation
1060      underneath shelf-ice with draughts of hundreds of meters.
1061     - works
1062     - to do: + include improved thermodynamics
1063              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1064                instead of new field kTopC
1065              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1066                instead of new field R_shelfIce and new code in ini_depth.F
1067                and ini_mask_etc.F?
1068              + adjust vertical mixing schemes?
1069    o seaice pkg:
1070     - add a cpp-flag to include a simple formula for a salinity dependent
1071       freezing point of sea water at the surface
1072     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1073       meridional stresses are now different (and hopefully correct)
1074    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1075       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1076       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1077    o pkg/diagnostics: add options and parameters for regional-statistics
1078       diagnostics ; define regions by reading a region-mask from a file
1079       (might add other options later)
1080    o pkg/bulk_force:
1081     - add option and parameters to use AIM surface-flux formulae.
1082     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1083       others forcing fields (defined in PARM05, parameter file "data") are loaded
1084       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1085     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1086     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1087     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1088       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1089     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1090    
1091    checkpoint58
1092    o add "--embed-source" option to genmake2 which, when the supporting
1093      tools can be compiled (as determined by genmake2) will turn on the
1094      embed_files package which then embeds the entire MITgcm source code
1095      (*.[fFhc] + Makefile) used for the build within the executable
1096      - requested by CNH but off by default
1097      - adds a paltry <9MB to the mitgcmuv executable in most cases
1098      - only writes the output when useEMBEDSRC in eedata is true
1099    o clean up 3-dim. relaxation codes:
1100      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1101      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1102      * Thanks to Tom Haine for testing!
1103    
1104    checkpoint57z_post
1105    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1106      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1107    o fix the pickup behavior for obcs in combination with ptracers
1108    o fix a bug in ptracers_external_fields_load
1109    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1110      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1111    o transfered surface NH pressure to eta field (if exactConserv).
1112    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1113         and update lab_sea output.txt file.
1114    o completing 3-dim. relaxation code: additional term
1115         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1116      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1117      * At compile time, in "EXF_OPTIONS.h" set
1118          #define  ALLOW_CLIMTEMP_RELAXATION
1119          #define  ALLOW_CLIMSALT_RELAXATION
1120      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1121          tauThetaClimRelax3Dim = 15552000.0,
1122          tauSaltClimRelax3Dim  = 15552000.0,
1123      * 3 cases:
1124          1) Use a constant-in-time 3-dim. field
1125          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1126          3) Real-time relax. to time-evolving prescribed field
1127    o Adding Laplacian-type smoothness constraint on
1128      initial and boundary (forcing) controls (ic, bc)
1129      * enable at compile-time via
1130        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1131      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1132      * Absolute scale somewhat unclear so far
1133      * no area weighting was included since no other cost term does so far
1134    
1135    checkpoint57y_post
1136    First step for a NLFS adjoint
1137    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1138    o new init. routines for calc_r_star, calc_surf_dr
1139    o still need to deal with ini_masks_etc
1140    o testreport seemed happy
1141    checkpoint57y_pre
1142    
1143    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1144    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1145    o add new offset feature to offline pkg (plus minor cleanup)
1146    o cfc fixes for final year of integration
1147    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1148      be in GCHEM_OPTIONS).
1149    
1150    checkpoint57x_post
1151    o fix testreport Pb in multiple test experiment.
1152    o cleanup our namelist syntax in verification:
1153      - make it more F95 standards compliant (some work still needed)
1154      - allows the vast majority of our tests to work with gfortran
1155    o Non-Hydrostatic:
1156     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1157     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1158    o Allow to apply AB on T,S rather than on AB(gT,gS):
1159     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1160     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1161       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1162     - need a "clever" read_pickup to restart from the other AB formulation
1163    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1164    o remove some unused variables (reduces number of compiler warnings)
1165    o adjoint
1166      * Disable useVariableViscosity for adjoint for time being
1167        (there are a number of extensive recomputations)
1168      * Initialize certain variables needed for adjoint
1169    
1170    checkpoint57w_post
1171    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1172                 fix the singleCpuIO RS version of MDSWRITEFIELD
1173       and add a WARNING if using globalFiles=T with multi-processors.
1174    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1175      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1176    o tracer advection scheme:
1177      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1178       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1179       was not very convenient).
1180      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1181       (further tests needed for the implicit DST & Flux-Limiter schemes).
1182    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1183      and sRef for convenience, handy, when you want to initialize
1184      ptracers in a large domain with a constant non-zero value. Also,
1185      untangle ptracers_init.F a little.
1186    
1187    checkpoint57v_post
1188    o change dome exp. to use variable viscosity in side-drag terms.
1189    o remove all the files from the cfc_offline test since they are now
1190      incorporated into tutorial_cfc_offline which has been producing
1191      identical results for a few days of testing
1192    o add new parameter: sideDragFactor to enable half-slip-side BC
1193      and change side-drag S/R to use viscosity from mom_calc_visc
1194      (can switch back by setting sideDragFactor=0.); affects results at
1195      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1196       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1197    o vorticity & strain are now computed without masking, to account for
1198      no-slip-side BC in variable viscosity calculation ; mask is applied
1199      anyway later on, before computing advection/coriolis terms.
1200    o modify exp4 to test new obcs support for reading from external files
1201      and for passive tracers
1202    o fix behavior of ptracers_monitor when monitor output is written to a
1203      netcdf-file; still not independent of monitor.F (writes in the same
1204      file).
1205    o change default value of tRef (put a uniform, meaningful value for ocean
1206      & atmos) and initialize sRef (was missing, as Martin mentioned).
1207    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1208      to be proportional to enstrophy dissipation length.  Thus,
1209       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1210      This is now consistent with Smagorinsky and with the manual.
1211    
1212    checkpoint57u_post
1213    o OBCS and PTRACERS: add open boundary support for passive tracers
1214      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1215        OB-values from file; this is not different from the way theta and salinity
1216        are treated
1217      - however, Orlanski-radiation conditions are not supported, and the model
1218        will stop if you use pTracers and Orlanski at the same time.
1219      - beefed up the rountine obcs_external_fields_load: now only those open
1220        boundary values are overwritten with values from files for which there
1221        are really files, otherwise the OB-fields remain untouched. This makes
1222        it possible to use different OBs at different ends of the domain (as
1223        with EXF)
1224    o reduce number of exch calls in shap_filt (s2).
1225    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1226      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1227    
1228    checkpoint57t_post
1229    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1230    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1231      same truncation, independent of the face number: affects affects several
1232      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1233    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1234      note that biharmonic viscosity + no-slip was not tested in any experiment.
1235    o fix bug in non-linear free-surf side-drag ; generate new output for
1236      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1237    o make mnc honor the writeBinaryPrec flag for most kinds of output
1238    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1239    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1240      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1241    o add brackets in multi-terms sum to get same truncation, independent of
1242      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1243      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1244    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1245      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1246      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1247      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1248      Suggested values of viscosity parameters found in mom_calc_visc.
1249      Many new viscosity diagnostics available.
1250    
1251    checkpoint57s_post
1252    o Add clearing-house for viscosity calculations, mom_calc_visc and
1253      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1254      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1255      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1256      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1257      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1258      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1259      ViscAhStrain and viscAhTension are now retired.
1260    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1261    o In response to JMC's bug report, genmake2 now ignores any soft-links
1262      that it finds in the *current* directory when searching for files.
1263      Soft-links found in any other source directories will still work as
1264      they did before.
1265    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1266      a C routine to unlimit the stack size
1267    o mnc-ify pkg/aim snapshot vars
1268    o mnc-ify pkg/land as requested by Daniel
1269    o various changes to mnc including:
1270      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1271      - output can now be grouped so that all files within a group
1272          change the ITER portion of their names in lock-step together
1273      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1274          and works with both EXCH1 and EXCH2 (but needs more testing)
1275      - writing works for all verification test cases w/ g77 on Linux
1276    
1277    checkpoint57r_post
1278    o make MNC variable initialization happen earlier
1279    o add diagnostics for (almost) each term of the momentum Eq.
1280    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1281    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1282    o remove MINIMAL_TAVE_OUTPUT option ;
1283      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1284    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1285      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1286    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1287    o add time-dependent SST, SSS control
1288    o cost terms in ecco/ modularized (new cost_generic.F)
1289    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1290    o new infrastructure for seaice model vs. obs misfits in seaice/
1291      * driver from the_main_loop.F is seaice_cost_driver.F
1292      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1293      * gradient check in Exp. 6a of natl_box_adjoint/
1294    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1295      (see README file)
1296    
1297    checkpoint57q_post
1298    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1299    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1300      - bug was reported by Jean-Michel and Ian Fenty
1301    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1302      update exp. cpl_aim+ocn output.
1303    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1304      Needed for high-res. runs with large global files
1305      to be able to limit tapelev size
1306    o Changed some tests for adjoint:
1307      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1308      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1309      * global_ocean.90x40x15/ back to default 3-level checkpointing
1310    o Modifications to enable scripted COMMON to MODULE conversion
1311      * verification/OpenAD/code/ has necessary scripts and description;
1312      * converts, compiles and runs successfully;
1313    
1314    checkpoint57p_post
1315    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1316    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1317      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1318    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1319    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1320      (was already the case for dissipation with mom_vecinv,
1321       and also the case for grad.PhiHyd when staggered-timeStep)
1322      This will allow to put dissipation out-off the AB time-stepping.
1323     Unfortunately, affects truncation error. Update output of exp. that "fails"
1324      (cg2d matching number) and leave the others for later: front_relax(10),
1325      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1326      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1327    
1328    checkpoint57o_post
1329    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1330      (2) its ready to be documented during the 20050801 DocFest
1331    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1332      for ideal_2D_oce and lab_sea on linux_ia32_g77
1333    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1334      in global1x1_tot/code_seaice_adj to access indices 32, 33
1335      (worth another tag)
1336    
1337    checkpoint57n_post
1338    o adding precip control xx_precip 32
1339    o adding swflux control xx_swflux 33
1340    o Replacing 10 forcing penalty cost routines by 1 generic.
1341    o Implementing partitioning in time-mean and variable adjustment
1342      for atmos. state.
1343    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1344    o in natl_box_adjoint:
1345      * updated exp 1 to 10
1346        (but does not have time-mean vs. variable split results yet)
1347    o updated global1x1/*_seaice_adj/
1348      to incorporate latest changes
1349    o enable useSingleCpuIO for mdsio vector routines
1350      (applies in particular to tapelev I/O)
1351    o removed inefficient K-loop in all active_file*control*.F
1352    
1353    checkpoint57m_post
1354    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
1355      and advect_cs (use EXCH-2 and standard cs-32 grid files).
1356    o pkg/exch2: filling of face-corner halo regions is optional
1357      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
1358    
1359    checkpoint57l_post
1360     tag before updating tutorials (pre-release-2)
1361    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
1362       for output and interpolation of input fields onto model grid)
1363    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
1364       Affects results of exp. rotating_tank ; update output.txt.
1365    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
1366          and taking the square quantity and/or using a fraction-weight field.
1367    o fix aim_diagnostics_init.F mate numbers.
1368    o add mnc output capability to diagnostics/diagstat and update
1369      our cvsignore files for the ACSII output generated
1370    
1371    checkpoint57k_post
1372    o lab_sea now uses diagnostics package and provides a suite of
1373      new EXF diagnostics output.
1374    
1375    checkpoint57j_post
1376    o exf
1377      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1378        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1379        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1380      * extended diagnostics output
1381        - now includes all EXF variables
1382        - hs, hl moved to common block
1383        - separate S/R for diagnostics, called after ctrl vector is added
1384        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1385        - EXFqnet contains true Qnet (i.e. includes qsw)
1386      * updated verif. lab_sea, global_with_exf
1387      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1388        to ensure that diagnostics sees a true EXFqnet
1389    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1390    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1391      several times with different frequencies.
1392    o mnc-ify the thsice package as requested by Daniel Enderton
1393      - the monitor--MNC output needs work
1394      - many attributes need to be added (most are currently blank)
1395    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1396      - many attributes need to be added (most are currently blank)
1397    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
1398    o add Sadourny like discretization to the 4th.O vorticity advection scheme
1399    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
1400      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
1401         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
1402    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
1403     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
1404    
1405    checkpoint57i_post
1406    o Diagnostics package was changed: diagnostic allocation is now deactivated
1407      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1408    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1409      add 1rst Order upwind vertical Shear.
1410    o add a quick fix for A/B checkpointing in OFFLINE mode
1411    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1412      end-run around the C/Fortran linking horror in eesup/src/timers.F
1413    o added pkg/runclock: allows user to terminate run based on wall clock
1414    o added non-hydrostatic scaling parameter: nh_am2
1415    o pkg/my82: futile attempt to make results compiler-independent by adding
1416      some "_d 0", etc. no effect.
1417    o for mnc output, fill the 'T' coordinate var with myTime and create a
1418      separate 'iter' variable for iteration count
1419    o pkg/diagnostics:
1420      add new capability: output of Global/Regional & per-level statistics ;
1421      tested against monitor output (including land & thSIce) on various exp.
1422    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1423    
1424    checkpoint57h_done
1425      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1426      data.diagnostics, data.gchem, data.ptracers) is done.
1427    
1428    o pkg/diagnostics: prepare for Global/Regional statistics.
1429      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1430    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1431      and rename it: DIFFERENT_MULTIPLE
1432    
1433    checkpoint57h_post
1434    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1435    o pkg/diagnostics: change output frequency, now in seconds (instead
1436      of Nb of iterations). This requires to change data.diagnostics.
1437    checkpoint57h_pre
1438    
1439    o in mnc, let the user create the output dir if both mnc_outdir_date
1440      and mnc_outdir_num are false
1441    o add fflags() to pkg/diagnostics which allows one to specify, on a
1442      per-file basis, the file precision [default behavior is unchanged]
1443    o added diagnostics to pkg/kpp, including computation of mixed layer
1444      depth based on a temperature/density criterion
1445    o updated verification/natl_box to test the new pkg/kpp diagnostics
1446    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1447    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1448    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1449      not mnc -- this mistake was found by JMC and is now corrected
1450    
1451    checkpoint57g_post
1452    o add Adams-Bashforth 3rd Order time stepping:
1453      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1454      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1455    checkpoint57g_pre
1456    
1457    o make lambda[Theta,Salt]ClimRelax spatially varying
1458      (default remains spatially uniform constant based on tau)
1459    o added new control variables
1460      * init. uVel, vVel, etanN
1461      * lambda[Theta,Salt]ClimRelax
1462    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1463      (suggested by G. Forget)
1464    
1465    checkpoint57f_post
1466    o add parameter "baseTime" = model base time = time at iteration zero
1467      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1468      account for baseTime shift
1469    o move Coriolis arrays from PARAMS.h to GRID.h
1470    checkpoint57f_pre
1471    
1472    o mnc-ifying the seaice package
1473    o introduced an alternative length scale calculation for use in the limiting
1474      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1475    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1476    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1477      as well as grad(vort3).  Made it compatible with both approximate form
1478      for the cubed sphere and full form of these gradients.  Added flag
1479      useFullLeith to select between approximate and full form.  
1480    o add "d0" in getcon.F to reduce differences between compilers/platforms
1481      update output.txt of exp. fizhi-gridalt-hs
1482    o change port_rand funtion to allow to set the seed.
1483    o fix obscure MNC bug involving conversion between reals and integers
1484      - it caused no problems with certain (eg. gcc, ifc) compilers but the
1485        new version is now more standards-compliant
1486    o adjoint-related modifications
1487      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
1488      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
1489      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
1490    
1491    checkpoint57e_post
1492    o Adding eddy stress controls a la Ferreira et al.
1493    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
1494    
1495    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
1496      update output.txt of exp. fizhi-gridalt-hs
1497    o add more "Z" dimensions and associated coordinate vars to MNC
1498    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
1499    o parameter calendarDumps: when set, approximate months (30-31 days) and years
1500      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
1501      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
1502      months and years.  Requires pkg/cal.
1503    o diagnostics: add pickup functionality
1504      - off by default for backwards compatibility
1505      - current version only uses MDSIO -- MNC will be added
1506    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
1507    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
1508    
1509    checkpoint57d_post
1510    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1511    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1512      output from the diagnostics package
1513    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1514    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1515      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1516    o add coordinate variables to the MNC output from the diagnostics package
1517    o change MNC-flags default value: true when useMNC=TRUE
1518    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1519      the ability (off by default) to read the grid information using MNC
1520    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1521    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1522    o do snap-shot diagnostics at the middle of the time-interval (instead of
1523      at the end).
1524    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1525      new test for AIM with thSIce + slab-ocean
1526    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1527    o move state variable diagnostics to the beginning of the time step ;
1528      (note: still needs some work specially for snap-shot diagnostics)
1529      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1530    
1531    checkpoint57c_post
1532    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1533    o generate new output.txt files on faulks with g77 & the new -ieee option
1534    checkpoint57c_pre
1535    
1536    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1537      update output.txt of exp. global_ocean.90x40x15
1538    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1539      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1540    o add saltFlux(+File) forcing capability with periodicExternalForcing
1541    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1542    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1543    o improvements for the MNC output from DIAGNOSTICS:
1544      - correct handling of the unlimitied dimension
1545      - all dims now have associated coordinate variables
1546      - variables located at U, V, and Corner ("Z") points are now written
1547        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1548        *all* data points are output
1549    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1550    o added pkg/seaice/seaice_monitor.F
1551    o mdsio_readfield.F can now read files visible only to master MPI process.
1552    o pkg/seaice: some test code for ice-modified ocean stress
1553    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1554      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1555      spurious negative numbers for precipitation and humidity.  Will cause
1556      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1557    o pkg/ctrl/
1558      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1559        May be enabled via doPackDiag
1560      *  introduce z-scaling of
1561         + gradient (doZscalePack) and
1562         + control (doZscaleUnpack)
1563    o pkg/mdsio/
1564      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1565      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1566    
1567    checkpoint57b_post
1568    o simplify options in diagnostics_fill arguments (remove weird combinations)
1569    o fix MNC coordinate variables so that they now contain per-face index
1570      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1571      general, EXCH2 grids are only aligned to a "local" coordinate system
1572    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1573    o Implement instantaneous output within pkg diagnostics:
1574      setting a negative frequency in data.diagnostics produces
1575     "snap-shot" output (as opposed to time-average if freq > 0)
1576    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1577      NOTE: change ptracer diagnostics name: use 2 characters to work with
1578            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1579    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1580      becomes the coordinate variable for the 'T' dimension
1581    o add CF-style coordinate variables to MNC
1582      - just a first cut:  numbers are meaningless on the cubesphere and
1583        missing along the T axis but otherwise it works!
1584    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
1585    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
1586    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
1587      this is based directly on what the model compute, so that the content of
1588      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
1589    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
1590    o clean up build options files for SunOS, in particular
1591      - remove -traditional from xmakedepend
1592      - change -xarch=v9 to -xarch=native for f77
1593      - restore use of make (not gmake)
1594      - add CC=gcc if using g77
1595    o changes per discussion of AM, JMC, & EH3 today:
1596      - move redundant "grid" variables out of "state" -- in preparation of
1597        creating proper CF-style coordinate variables and in recognition
1598        that any/all grid variables can be easily copied (eg. w/NCO) from
1599        the grid files into any of the other NetCDF files
1600      - *always* output grid variables with MDSIO (this will eventually be
1601        changed)
1602      - output MNC grid file if useMNC is true
1603    o every instance of _END_MASTER() has been found and replaced with
1604      _END_MASTER( myThid ) in order to satisfy certain picky Sun
1605      preprocessors
1606    o re-arrange diagnostics pkg initialisation:
1607     - allow each package to extend the available diagnostics list
1608     - add some checking and fix small problems (multi-threaded, ...)
1609     - new S/R diagnostics_fill (replace fill_diagnostics):
1610       look through the short list of active diag. (instead of the long list)
1611       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
1612    
1613    checkpoint57a_post
1614    o this set of changes restores TAMC compatibility
1615      tested for global_ocean.90x40x15 adjoint on trough
1616      (what a pain)
1617    
1618    checkpoint57a_pre
1619    o some modifs in tools/build_options for sunos
1620    o call ctrl_pack for ctrl at end for optimcycle=0
1621    
1622    checkpoint57
1623    o add horizontal bi-harmonic viscosity for vertical velocity
1624      - new parameter viscA4W (defaults to viscA4)
1625      - affects only non-hydrostatic code
1626      - to be done: no-slip lateral boundary conditions
1627    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1628    o implement Implicit Vertical advection for pTracers
1629    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1630      (implemented also for implicit vertical diffusion & advection)
1631    o OBCS: extend application of tracer open boundary conditions
1632      to a strip beyond the boundary of width Olx/Oly
1633    o add call monitor to TAF set of required calls (flow directives)
1634      and include in natl_box_adjoint
1635    o untangle a few ifdefs related to cost, ctrl, autodiff
1636      untangel a few ALLOW_ECCO_OPTIMIZATION
1637    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1638      (theta2, salt2 in ecco_cost_weights)
1639    
1640    checkpoint56c_post
1641    o OBCS as control variables
1642      - update ctrl_ad_diff.list, obcs_ad_diff.list
1643      - remove balance of obcs controls from default
1644      - fix index bug nobcs in ctrl_init
1645      - fix dummy fields filen in ctrl_pack
1646      - add dummy weights for obcs
1647    o lsopt: comment out fort.94 output
1648    o optim:
1649      - remove unnecessary header files
1650      - adjusted namelists
1651      - add xerbla.F to Makefile
1652    o exf:
1653      - multiple modifications of exf_check_range
1654      - unit change in exf_init_runoff from [m/year] to [m/s]
1655    o mdsio:
1656      - i/o-vector change debugLevel from debLevA to debLevB
1657    
1658    checkpoint56b_post
1659    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1660      is called from DO_THE_MODEL_IO
1661      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1662      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1663      - clean up PTRACERS_WRITE_TIMEAVE a little
1664    o add another verification experiment that tests both the cfc-pkg and
1665      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1666      reactive tendencies treated inline with regular timestepping
1667    o testreport previously did a lousy job of comparing small numbers, so
1668      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1669      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1670      testreport.
1671    o ptracers_monitor: bug fix for MPI
1672    
1673    checkpoint56a_post
1674    o GCHEM: finish reorganizating the package
1675      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1676        (introduces another 3D-array for each passive tracer, but only if
1677        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1678        gchemTendency is not needed because the timestep is done separately)
1679      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1680      - GCHEM is now---more or less cleanly---separate from PTRACERS
1681      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1682        so clear to me how that should be done in a general way.
1683    o CFC: improve formatting of output in CFC_ATMOS
1684    o PTRACERS:
1685      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1686        that ALL experiments with ptracers enable can be checked. This makes
1687        GCHEM_MONITOR obsolete.
1688      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1689        monitorFreq
1690      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1691    o add PTRACERS (PTR0[1-5]) to testreport output
1692    o exf_check_range:
1693      * default changed to .TRUE.
1694      * will check values for niter0 if debLevA, every timestep if debLevB
1695      * STOP in exf_check_range if 'out of range'
1696      * range chosen generous to allow for potential extema
1697      TBD: a version with stricter range
1698           permitted range would be runtime parameters
1699    o GMredi:
1700      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1701      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
1702      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
1703    o GCHEM:
1704      - move call to GCHEM_FORCING_SEP, so that it is now called before
1705        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
1706      - introduced a useGCHEM runtime flag and applied it everywhere.
1707      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1708        this flag is now only visible within GCHEM-pkg routines.
1709      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1710        be replaced by a 3D array that is computed before thermodynamics; for
1711        this, the tracer ID iTracer had to be included into the parameter list
1712        of ptracers_forcing
1713      - set up forward_step to call gchem_forcing, that will replace
1714        gchem_forcing_int in ptracers_forcing
1715      - cleaning up
1716    o small cleaning of exch2: remove files that are also in eesupp/src
1717    
1718    checkpoint56
1719    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
1720    o mnc: cleanup "full" files--fixes out-of-memory problem
1721    o ECCO-GODAE
1722      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
1723      * fully merged and updated from SIO code
1724        windstress sign change affects
1725        - exf_inscal_[u/v]stress
1726        - sign of xx_tau[u/v] adjustments
1727        - signs in cost_scat
1728      * ctrl_get_gen: avoid update of tau[u/v] for first few days
1729      * natl_box_adjoint updated and compressed
1730      * 2-level checkpoint switch added
1731        (tested in EXP. 1 of natl_box_adjoint)
1732      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
1733    o SVD
1734      * first complete, non-hacked version for SVD calculations
1735      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
1736        performed via direct access files admtlm_vector.it????
1737        (via ctrl_[un]pack)
1738      * optimcycle is used for ARPACK iteration counter
1739        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
1740      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
1741        and add linear transforms where necessary
1742      * controls are initial/final SST, SSS (can be extended; need to check
1743        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
1744    o mdsio: filename info to both stderr, stdout
1745    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
1746      from sign change
1747    
1748    checkpoint55j_post
1749    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
1750      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1751    o add consistent build directories and .cvsignore files to verification
1752    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
1753    o make all subroutines 30 or less characters in length for certain older
1754      compilers to work (a thorough search only turns up two routines in
1755      pkg/ptracers)
1756    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
1757      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1758    
1759    checkpoint55i_post
1760    o change arrays for total vertical diffusivity (2.D if explicit,
1761      3.D if implicit) ; each ptracer uses its own background value.
1762    o added mnc/NetCDF output capability to ocn_compon_interf
1763      - added bits to verification/cpl_aim+ocn so that it can run on
1764        ITRDA and other clusters without the mpirun "-wd" option
1765    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
1766      configuration
1767    o give MNC the ability to create additional files rather than
1768      exceeding a specified file size limit "MNC_MAX_FILESIZE"
1769      - the default is just less than 2GB which is a practical limit
1770        on many systems
1771    o Compute the non-local term using either KPP vertical diffusivity (=default)
1772       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
1773    
1774    checkpoint55h_post
1775    o add verification test "vermix"
1776    o remove all the *_ioinc flags and replace with the single global
1777      outputTypesInclusive flag
1778    o allow to set a vertical profile of vertical diffusivity for T & S
1779    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
1780    o useMNC moved from data.mnc to data.pkg
1781    
1782    checkpoint55g_post
1783    o Renaming carbon AD experiments to comply with testreport conventions
1784    o Updating adjoint of Held-Suarez hs94.1x64x5
1785    o Fixing directives for non-ECCO forward_step, after ECCO directives
1786      have been fixed to avoid recomp. of do_oceanic_phys
1787      Works well for global_ocean.90x40x15,
1788      but recomp. issue remains for carbon
1789    o Updating adjoint output for natl_box_adjoint after
1790      pkg/ecco has been modified (see taga c55d_post)
1791    
1792    checkpoint55f_post
1793    o rename to timeave_init_fixed
1794    
1795    checkpoint55e_post
1796    o some delicate re-shuffle of store directives to avoid one
1797      extra call of do_oceanic_physics
1798      affects ecco_the_main_loop.F, do_oceanic_physics.F
1799      checkpoint_lev1_directives.h
1800    o NB: this may break global_ocean adjoint temporarily,
1801      but it is clear how to fix it. Will do later, need this now.
1802    
1803    checkpoint55d_post
1804    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1805    o ecco_cost_weights is modified to 1x1 runs
1806    o modifs to allow observations to be read in as
1807      single file or yearly files
1808    o enable to read exf forcing fields as either
1809      single file or yearly files (flag useExfYearlyFields)
1810    checkpoint55d_pre
1811    
1812    o switch between 2-level and 3-level checkpointing
1813    o add ability of MNC to write local and "partial" (eg. 2D slices where
1814      the full 3D field is never actually stored) arrays to NetCDF files
1815      with the correct (that is, the complete multi-dimensional) set of
1816      array indicies
1817      - used in mom_vecinv() to write the diagFreq output
1818      - tested (demonstrated) in verification/aim.5l_cs
1819    o further mnc-ification
1820      - add verification/lab_sea to the list with mnc setups
1821      - fix undefined mnc v-names in cd_code
1822      - add kpp to mnc output (both snapshot and timeave)
1823    o non-hydrostatic code
1824      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1825        in calc_gw.F
1826      - defaults to viscAh
1827      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1828        friction or Leith) in non-hydrostatic mode, as long as there is
1829        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1830    o pkg/cost
1831      extend simple cost functions to treat time mean quantities
1832      (T,U,V) via cost_accumulate_state from cost_tile
1833    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1834        be 2 times larger than the minimum size the advection scheme requires.
1835        now get a perfect conservation of salt in advect_cs test-exp (updated)
1836    o GGL90 (Gaspar's TKE mixed layer)
1837      - add horizontal diffusion of TKE, requires exchanges in
1838        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1839        default. In OPA there is no horizontal diffusion of TKE but the
1840        mixing coefficients are computed from a horizontal average of TKE of
1841        6 points or so. I think that diffusion has a little more physical
1842        justification.
1843      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1844        was in vain)
1845      - mask tke-variable in ggl90_init
1846    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1847    o fix biharmonic diffusion on CS-grid.
1848    o more obcs stuff
1849      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1850        for reading boundary values. This routine is called from
1851        obcs_prescribe_read
1852      - updated obcs_check
1853      - changed sponge layer relaxation parameter units for days to seconds
1854      - turned off sponge layer by default
1855      - changed argument list of OBCS_CALC to myTime+deltaTclock
1856      - fixed about 35 bugs in obcs_external_fields_load
1857    
1858    checkpoint55c_post
1859    o obcs stuff
1860      - new runtime flags useOBCSprescribe, useOBCSbalance
1861      - re-arranged obcs_calc
1862      - moved exf_getobcs to obcs_prescibe_read
1863        obcs_prescibe_read is called after ORLANSKI stuff
1864        and independent of it (executable can contain all).
1865      - updated obcs_check
1866      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1867        These may be necessary only if tangential velocities are
1868        prescribed at OB, not sure, needs testing.
1869    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1870      which simplifies the calls and passes the ifc check-bounds test
1871    
1872    checkpoint55b_post
1873    o add a 2D scalar, Z location, exchange_2 routine.
1874    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1875      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1876      affects advect_cs results (for the wrong reason): update output.txt
1877    o use a more standard discretization for biharmonic viscosity ;
1878     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1879      affects results of dome set-up: update output.txt
1880    o fix gad_advection.F (CubedSphere part), back to version 1.23
1881    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1882    
1883    checkpoint55a_post
1884    o merged code to
1885      * prescribe/read time-dependent open boundaries
1886        (works in conjunction with exf, cal)
1887      * sponge layer code for open boundaries
1888      * each boundary N/S/E/W now has its own CPP option
1889        (healthy for the adjoint)
1890    
1891    checkpoint55
1892    o up-to-date adjoint of previous breaks
1893      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1894      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1895      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1896      - carbon: * remove tr1-related adjoint verification
1897                * add ptracer as control variable
1898    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1899      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1900    
1901    checkpoint54f_post
1902    o in verification/carbin/ remove experiment related to
1903      ALLOW_PASSIVE_TRACER (array tr1 etc)
1904      code_ad/ input_ad/ results_ad
1905    
1906    o add two new packages
1907      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1908        + subject to optimization (memory)
1909      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1910        + subject to reordering (many GOTOs in the original code)
1911        + so far opps is called for every (i,j) point, and then operates in
1912          the vertical; one may want to reorder the scheme in order operate in
1913          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1914          fields)
1915    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1916      - all verification tests compile and run with linux_ia32_g77
1917      - defaults are compatible with current input files--nothing
1918        should change if you were not previously using MNC
1919      - MNC output has been added in numerous places (eg. timeave)
1920        but there are still a few writes not yet do-able with MNC
1921        (this is in progress)
1922      - flags now allow for either/or/both use of MDSIO and MNC and
1923        documentation will soon follow
1924      - numerous small formatting cleanups for ProTeX
1925    o add version info (via BUILD_INFO.h) to MNC and stdout
1926    
1927    checkpoint54e_post
1928    o add two new packages
1929      - pp81 (Packanowski and Philander, 1981), Richardson number and
1930        stratification dependent mixing
1931      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1932      - these scheme operate in a similar manner as KPP (without ghat, of
1933        course), however there is only one diffusivity that is used for both
1934        temperature and salinity (and passive tracers)ç
1935    o add offline package
1936    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1937      provided by Stephanie Dutkiewicz
1938    o genmake2: add ability to search for C compilers and cleanup test output
1939      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1940    
1941    checkpoint54d_post
1942    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1943    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1944      leading to additional shift by 5 days each year of integration
1945       (i.e. leading to considerable offset over the years)
1946    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1947    o start with no AB and no initial filtering (staggerTimeStep):
1948      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1949    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1950      (external loading & cpl import/export stay in forward_step.F)
1951    o update coupling interface to work with new staggerTimeStep
1952    o change MDSIO ptracers_pickup.
1953    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1954    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1955    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1956    
1957    checkpoint54c_post
1958    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1959      this affects (truncation error) output.txt of test-exp:
1960       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1961    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1962    o change Qnet to always be the net heat flux, (+upward).
1963      affects (truncation error) output of natl_box exp.: updated
1964    o define the max number of passive tracers in PTRACERS_SIZE.h
1965    o start to test mnc routinely in exp0
1966    o add sea-ice loading (sIceLoad) as a new forcing field.
1967    
1968    checkpoint54b_post
1969    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1970       impressive on Altix and Opteron systems)
1971    o diagnostics can now write NetCDF files through the mnc package
1972    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1973    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1974    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1975      affects (truncation error) output of lab_sea & natl_box exp.: updated
1976    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1977    
1978    checkpoint54a_post
1979    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1980    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1981    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1982    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1983      + internal_wave (shift in writing cg2d_ini_res)
1984    checkpoint54a_pre
1985    
1986    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1987      - modified verification/lab_sea and natl_box_adjoint accordingly
1988    
1989    checkpoint54
1990    checkpoint53g_post
1991    o prepare splitting of thermodynamics: store convect.counter in common block
1992    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1993      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1994    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1995    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1996    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1997    o restore adjointability
1998    
1999    checkpoint53f_post
2000    o modifications that affect AIM experiment results (update output.txt):
2001      - no advection of S at top interface Nr (pkg/generic_advdiff)
2002      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
2003    o AIM pkg:
2004      - include stability function into surf.Flux derivative relative to Tsurf
2005      - calculate clear-sky radiation & surface temp. change (for diagnostics)
2006    
2007    checkpoint53e_post
2008    o merged cylindrical coord configuration
2009    o added rotating_tank experiment
2010    checkpoint53e_pre
2011    
2012    checkpoint53d_post
2013    o faulks upgraded: re-generate output.txt that have changed:
2014       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
2015    o Added Bryan and Lewis, 1979, vertical diffusivity profile
2016    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
2017    o added Sadourny discretization of Coriolis
2018      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
2019      - re-enabled use of omega3 (useAbsVorticity)
2020    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
2021      vector-invariant equations
2022      - note: does *NOT* yet use same variable visc. for no-slip BC's.
2023    o recoded the lateral boundary conditions for non-hydrostatic w, this time
2024      hopefully without new bugs
2025      - still to do: biharmonic friction for non-hydrostatic w
2026    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
2027    o regenerated output for global_ocean_ebm (using -ieee)
2028    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
2029      of mom_common/
2030      - simple re-arrangement of instructions within computing loop
2031    checkpoint53d_pre
2032    
2033    checkpoint53c_post
2034    o new version of coupler for AIM+thSIce and Ocean models
2035     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
2036     - land: change Evaporation of snow
2037     - aim with thSIce: fix bug in snow-precip.
2038    o changes to calc_gw.F
2039     - bug fix for w^2 term near the bottom boundary
2040     - (hopefully) improve the lateral slip boundary condtions for use with
2041        partial/looped cells
2042      - because the bug fix changes two verification experiments anyway (exp5
2043        and plume on slope), change the lateral boundary condition from half slip
2044        to the value of no_slip_sides
2045    o ebm package wasnt quite up to the parallel task. Fixed that.
2046    o Adjoint of EBM package + verification
2047      * TLM OK
2048      * ADM not sufficient accuracy yet (needs further testing)
2049    
2050    checkpoint53b_post
2051    o Commiting new energy balance model to repository
2052      * package is pkg/ebm
2053      * verif. is verification/global_ocean_ebm
2054      * references are in ebm_driver.F
2055    C      * X. Wang, P. Stone and J. Marotzke, 1999:
2056    C        Global thermohaline circulation. Part I:
2057    C        Sensitivity to atmospheric moisture transport.
2058    C        J. Climate 12(1), 71-82
2059    C      * X. Wang, P. Stone and J. Marotzke, 1999:
2060    C        Global thermohaline circulation. Part II:
2061    C        Sensitivity with interactive transport.
2062    C        J. Climate 12(1), 83-91
2063    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
2064    C        Destabilization of the thermohaline circulation
2065    C        by atmospheric eddy transports.
2066    C        J. Climate 7(12), 1870-1882
2067    o Will need long integration testing.
2068    checkpoint53b_pre
2069    
2070    o created pkg/mom_common in preparation for variable viscosity code
2071    o renamed and split ini_mnc_io
2072    o pkg/land: only liquid water can diffuse or run-off
2073    o AIM using land: soil wetness availability account for snow
2074    o added printMapIncludesZeros to EEPARMS namelist
2075    
2076    checkpoint53a_post
2077    o restore TAMC compatiility for exf_constants.h
2078      (no usage of _d in .h)
2079    o Additional storing in KPP in an attempt to fix
2080      TAMC problem with adjoint of KPP code.
2081      (no success...)
2082      Identical code works fine with TAF.
2083    o Fixed verification/natl_box_adjoint experiments.
2084      Initial conditions for Experiments 4 and 5 are now
2085      set to "SEAICE_initialHEFF=0", which is more reasonable,
2086      and hence gives results closer to that of Experiment 2.
2087      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
2088    
2089    checkpoint53
2090    o stable checkpoint with up to date adjoint
2091      TLM tests only run for 1st grdchk at the moment. Its unclear if
2092      this is a code problem or a problem with resetting code for g_
2093      variables that is being autogenerated wrong.
2094      Otherwise:
2095       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
2096       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
2097         are both still in chaos following their security messes.
2098    
2099    checkpoint52n_post
2100    o various build (mostly genmake2) changes including:
2101      - ability to build/run more easily within Cygwin and MacOS X
2102      - more complicated Makefiles with a stronger dependence on Gnu Make
2103    o pkg/seaice modifications
2104      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
2105        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
2106        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
2107      - changed proxy for geostrophic velocity and updated
2108        verification/lab_sea/results/* accordingly
2109      - removed ADI dynamic solver from pkg/seaice
2110      - replaced all occurrences of 1/CSTICE or 1/CSUICE
2111        they caused a segmentation fault under certain circumstances
2112      - removed unused field WATR
2113    o bug fix in exf-package:
2114      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
2115         now reflect that.
2116    o small fixes in the cal-package:
2117      - set reference date to first of January for the 'model'-calendar
2118      - failing of cal_CheckDate in cal_FullDate now actually results in a
2119        warning
2120    o small modifications in exf-package to increase flexibility:
2121      - change climtempfreeze from a constant to a runtime parameter that
2122        is specified in data.exf_clim (default = -1.9)
2123      - introduce runtime parameter windstressmax (default = 2.0) that is
2124        specified in data.exf
2125    o fix in pkg/thsice:
2126      - update Evap (Tsf changes) to be consistent with Latent heat flux
2127      - maintain snow precipitation unchanged (even if Tsf >=0).
2128     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
2129    
2130    checkpoint52m_post
2131    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
2132      this does not change any of the results, because myIter=0 in swfrac always
2133      lead to jwtype=2 (the default anyway), but the call makes little sense
2134      as a default
2135    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated

2143    o monitor package can write to NetCDF files and/or STDOUT
2144    o fix re-definition bug in MNC_GRID_INIT_ALL()
2145    o doc/api_reference added
2146      - a framework for building an API Reference Manual using all
2147        the "protex" comments embedded in the code
2148      - see pkg/generic_advdiff, pkg/mnc for examples
2149    o MNC:
2150      - make myThid the last argument for all subroutines
2151      - new default for the grid files: NO halos
2152      - add useMNC and other run-time flags
2153      - separate per-file-group handling of the unlimited dimension
2154      - early initialization of MNC w/ flags read at the eeboot stage
2155        and lookup tables set in initialize_fixed
2156      - write all MNC output to a freshly-created directory
2157    o thermodynamics sea-ice (thsice) is now tested with testreport.
2158    o test exp. advect_cs: use the standard cs32 grid ; update output.
2159    o Added functionality to grdchk:
2160      pick global i,j,k position (or nearest wet) where to perform check.
2161    
2162    checkpoint52l_post
2163    o new land formulation:
2164      a) use ground enthalpy as prognostic variable to ensure exact
2165         energy conservation.
2166      b) account for water temperature and for latent heat of freezing
2167         in all processes (rain, run-off, ground storage)
2168      c) compute surface and ground temperature implicitly.
2169    o aim_v23 modification for new land model:
2170      a) Treat separately land / ocean / sea-ice surface fluxes
2171         to allow implicit computation of land & sea-ice surface temp.
2172      b) add snow precipitation.
2173    checkpoint52l_pre
2174    
2175    o fix problem (when 1 tile is empty) in min/max monitor.
2176    o fix bug in timeAve (u,vZetatave in common block)

2183    o aim.5l_cs: modify sea-ice fraction input file ; update output
2184    o exf: Adding simple range check routine for exf fields after read
2185    
2186    checkpoint52k_post
2187    o removed top-level directory "diags"
2188      - we migrated these functions to pkg/timeave a long time ago
2189    o fixed bug introduced in pkg/monitor
2190    o accuracy ctrlprec = 32 insuffient for gradient checks using
2191      averaged fields (I/O via cost_averages)
2192      -> use ctrl.h in active_file*.F to control I/O precision.
2193    o paramter list of CALL ADTHE_MAIN_LOOP
2194    o added initial do_the_model_io to ecco
2195    o set all ...Freq to zero after cost_final
2196      taveFreq, dumpFreq, pChkptFreq
2197    o MAIN and ECCO differentiability restored
2198    
2199    checkpoint52j_post
2200    o fix nchklev in tamc.h for global_ocean...
2201    o Bringing flow and store directives up-to-date
2202    o Really weird thing!
2203      call do_the_model_io from the_main_loop with parameters
2204      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
2205      TAF places a faulty re-call of initialise_varia
2206      after cost_final call which should not be there!
2207    checkpoint52j_pre
2208    
2209    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
2210      error messages
2211    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
2212    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
2213      debug output
2214    o modfied mdsio_writefield.F to handle non-global files under exch2
2215    o update AIM Cubed-Sphere exp (aim.5l_cs):
2216      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
2217    o update AIM Equatorial Channel exp:
2218      use standard aim_v23 pkg and change the SST fields to be more realistic.
2219    o globalFile now works with exch2
2220    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
2221      mon_vort3.F to make exch2 friendly with >1 tile per cube face
2222    o limit timeave output for hi-res integrations
2223    
2224    checkpoint52i_post
2225    o removed CPP_EEOPTIONS.h from verification/*/code

2227    checkpoint52i_pre
2228    
2229    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
2230      the old pkg/aim).
2231    
2232    checkpoint52h_pre
2233    o shortened offending lines in exch2_send_rx?.template
2234    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
2235  o genmake2: add build & execute test for NetCDF code  o genmake2: add build & execute test for NetCDF code
2236  o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed  o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
2237    old grid files, moved CPP_EEMACROS.h to pkg/exch2    old grid files, moved CPP_EEMACROS.h to pkg/exch2
2238  o added useSingleCPUIO flag to monitor.F and mon_out.F  o added useSingleCPUIO flag to monitor.F and mon_out.F
2239    o added temporary hack for sea-ice dynamics on the cube:
2240      metric terms are ignored and it is assumed that
2241      there is no sea-ice on cube faces 1, 2, 4, and 5.
2242    
2243  checkpoint52f_post  checkpoint52f_post
2244  o added exch2 cube routines to pkg/exch2  o added exch2 cube routines to pkg/exch2
