4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o adding precip control xx_precip  o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
8  o moved ptracer ctrl index 17 -> 32    SX vector computer.
9    o pkg/seaice:
10      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
11        seaice forcing fields can now be read only through pkg/exf
12      - removed some unused halos
13    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
14    o pkg/exf: added CPP option EXF_SUBTRACT_UVVEL_FROM_UVWIND for subtracting
15      UVEL and VVEL from UWIND and VWIND prior to applying bulk formulae.
16    
17    checkpoint59k
18    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
19      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
20    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
21      all experiments pass when compile with un-initilised var. checking option.
22    o added pkg/salt_plume
23    o script to test restart (for now, in MITgcm_contrib/jmc_script)
24    o pkg/seaice: new read/write pickup version.
25      read meta file and write only fields which are needed to restart.
26      ( same logic as main pickup file ; also using pickupStrictlyMatch )
27    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
28    o lab_sea.hb87: modify the domain & update output.hb87.txt :
29      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
30      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
31      process. Fixed here by closing the domain at the Northern boundary.
32    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
33    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
34      a set of consecutive levels in/from a 3-D array.
35    o pkg/ptracers:
36      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
37      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
38    
39    checkpoint59j
40    o in pkgs: dic, obcs, offline, rbcs:
41      standard way to compute coeff. for time interpolation between 2 time reccords
42      which retains full precision (& make results less dependent on compiler).
43      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
44    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
45      packages instead of reading ice cover and wind speed separately
46    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
47     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
48      to allow to compile customized code before the update)
49    o cleaning-up:
50      - fix CPP instruction syntax in pkg/obcs
51      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
52        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
53      - fix some threads issue in IO parts.
54    o pkg/dic:
55      - add tons of "_d 0" (--> much better testreports !)
56       and then update outputs of tutorial_global_oce_biogeo
57    o pkg/mom_fluxform:
58      add a special version of momentum advection intended to conserve momentum
59      next to a bathymetry step or a coastline edge. (default = off = #undef)
60    o new read/write pickup version:
61      - for now, only implemented for main (mdsio) pickup file.
62      - write out only what is needed to restart; merge pickup_nh , pickup_ph
63        and main pickup together.
64      - read meta file; read only what is needed to restart; stop if a field
65        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
66        if it make sense (even if the restart is not perfect).
67      - if no meta file, assume that pickup to read corresponds exactly to
68        a pickup that would currently be written.
69      - read pickup written in the old format (until checkpoint59i) if it
70        recognizes an old meta file (no field-list).
71      - add a meta file in exp. which starts from a pickup: 2 cases:
72        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
73         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
74        b) a meta file describing the content of the associated pickup file
75         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
76    o pkg/mdsio & pkg/rw:
77      - new routine to read a meta file ; new set of routine to read
78        Multiple-fields file (with meta file).
79    o added open boundary conditions capability for seaice
80        HSNOW, HSALT, UICE, and VICE
81    
82    checkpoint59i
83    o adjoint:
84      * fix multiDimAdvection adjoint
85        (partial recomputation problem by TAF for fVerT(:,:,kDown)
86        and comlev1 size definition (maxpass vs. max. number of tracers)
87      * verification/global_ocean.90x45x15 adjoint now tests
88        NLFS and multiDimAdvection using DST3 (=30)
89      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
90    o pkg/kpp: add "_d 0" to real constant (if missing);
91      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
92      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
93    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
94      for internal parameters related to restart process (formerly from PARAMS.h)
95      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
96    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
97      as argument. (only atm2d & obcs write_pickup have not yet been updated)
98    o pkg/monitor:
99      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
100      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
101      - account for deep Atmosphere factor and density factor (anelastic)
102    o added open boundary conditions capability for seaice HEFF and AREA
103    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
104      thermodynamics
105      - requires a little reorganization, which affects the testreport results
106        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
107        so that now the conservative form is tested
108      - add a few comments
109    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
110    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
111    o add new diagnostics to seaice: advective, diffusive fluxes (only for
112      multidim-advection, for scheme 2 they are not filled) and transports,
113      thermodynamic growth rates
114    o change units of EmPmR (inside the code, + within coupling interface)
115      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
116      Affects results @ truncation level (cg2d match) and update output of
117       experiments: lab_sea(6), global_ocean.90x40x15(10),
118      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
119      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
120      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
121      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
122    
123    checkpoint59h
124    o pkg/exf:
125      - improve vectorization by moving if-statement out of loops in
126        exf_mapfields, exf_radiation
127      - exf_bulkformulae.F: introduce 2D fields and vectorize code
128    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
129    o testreport:
130      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
131        monitor & update offline_exf_seaice exp. output.
132      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
133    o pkg/seaice:
134      - bug fix in the evp solver: boundary conditions were affected be
135        masking of zMax/zMin (changes results)
136      - minor bug fix in boundary conditions in seaice_calc_strainrates
137        (changes results for no_slip)
138      - seaice_lsr.F: make interpolation of eta dependent on boundaries
139      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
140      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
141        stress formulation and no-slip boundary conditions
142    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
143      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
144    o pkg/seaice: a first HSALT time stepping equation has been checked in
145    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
146      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
147      without requiring DO-IF statements
148    o pkg/thsice:
149      use continuous power-law function for partition of energy between lateral
150      melting/freezing and thinning/thickening ; old code using step function
151      still available with #undef THSICE_FRACEN_POWERLAW
152      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
153    o testreport: change AD testing : check against results/output_adm.txt
154      using same scripts as for forward test.
155    
156    checkpoint59g
157    o adjoint testing: in preparation for changing testreport:
158      - output format: cost and grad written on separated lines
159      - ad output results in directory "results" (instead of "results_ad")
160    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
161    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
162    o pkg/ecco: allow user defined cost function contributions
163    o testreport:
164      Allow to choose (per experiment) the list of tested output variables
165       and the main variable (used to issue a pass/FAIL ) ;
166      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
167      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
168      Also modify printing of summary:
169       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
170       b) echo the list of tested variables in the individual summary.txt of
171          each experiment.
172    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
173      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
174      (but still depend on the tile decompostion of the domain).
175    o pkg/seaice: change a discretization detail to make the B-grid code
176      "more symmetric". This change is likely to remove all "ridges/leads" that
177      where quasi-aligned with the grid in B-grid solutions. It may also be
178      the solution to the stress coupling issues with the B-grid.
179    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
180      remove .cvsignore from input dir. (since testreport no longer run here).
181    o pkg/thsice:
182     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
183     - fix reshaping of sea-ice just after advection:
184       melt all the ice only if ice-volume is too small.
185     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
186       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
187     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
188    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
189      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
190    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
191      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
192      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
193      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
194      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
195      -> update output.txt
196    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
197     this affects truncation error: -> update output.txt of exp:
198      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
199      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
200    
201    checkpoint59f
202    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
203    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
204      a bounded range (in forward mode)
205    o pkg/ecco, ctrl, autodiff and mom_common:
206     internal parameter controls, completements of implementations
207    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
208    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
209      (not seem any difference in testing results).
210    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
211       at face corners.
212    o pkg/generic_advdiff:
213     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
214      loop range indices for computing vertical advection tendency
215      and do the calculation in the interior only (no overlap) ;
216      for now, only implemented for SOM advection (to save CPU time).
217     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
218    o exch2 adjoint
219      First set of changes:
220      - add exch2 hand-written adjoint templates
221      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
222        This will require cleanup in pkg/autodiff/*.F
223        (changed routines currently kept separate in verif. code/)
224      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
225        that used to hide exch2 or cubed-sphere specific code
226        (commented via 'cph-exch2')
227    o pkg/seaice
228      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
229    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
230       output of global_ocean.cs32x15.thsice .
231    
232    checkpoint59e
233    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
234      for B-grid vector (not yet tested) and C-grid vector (<- only used
235      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
236    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
237      (#ifdef ALLOW_SALT_PLUME)
238    o gather_2d/scatter_2d: removed halo regions
239    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
240      scheme and the corresponding test case (under front_relax dir). For now,
241      only available with Skew-flux form and not yet tested in realistic set-up.
242      adjoint: store directives updated, but gradient checks deteriorated,
243      so maybe GM/Redi adjoint is now broken.
244    o seaice adjoint
245      * add AREA, HEFF, HSNOW as control variable
246        (should not change lab_sea results)
247      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
248    o pkg/seaice:
249      * added computation of saltFlux in seaice_growth;
250        For time being, sea ice salinity is assumed constant
251        contribution of snow flooding to freshening of sea ice is neglected.
252        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
253        defaults to 0.0 in order to maintain backward compatibility.
254        Typical values for SEAICE_salinity are 4 to 10 g/kg.
255      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
256      * added SEAICE_availHeatFrac, which specifies fraction of surface level
257        heat content used to melt or grow ice
258      * commented out cap of HICE: it helps keep ice thinner
259      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
260      * applied OBCS T/S mask to HEFFM sea ice mask
261    
262    checkpoint59d
263    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
264     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
265     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
266    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
267     and change default value of parameter "GM_Small_Number";
268     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
269       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
270       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
271    o pkg/ecco: cost function when applying pkg/smooth to controls
272    o pkg/ctrl: add forcingPrecond run time parameter
273    o pkg/seaice:
274     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
275     - fix bug in metric terms of u-equation in LSR solver (implicit part),
276       changes verification/lab_sea
277     - rearrange implicit part of u-equation in LSR solver to make it easier to
278       read, understand, and debug. This causes changes at the truncation level.
279     - fix (serious) bug in the boundary conditions (sign error in the implicit
280       part) of the LSR solver. Changes all LSR results.
281     - fixed problem with HSNOW initialization to avoid thick snow when AREA
282       is initilized with small values - does not change lab_sea results.
283     - added HsnowFile initialization capability
284    o pkg/smooth: addition to model/src and pkg/ctrl so allow
285     initialization of pkg/smooth and application to control vector
286    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
287    o dependencies: pkg/profiles requires pkg/cal
288    o pkg/profiles:
289     - added option ALLOW_PROFILES_GENERICGRID
290         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
291         that interpolation information (grid points and coefficients) is provided
292         within the netcdf input files.
293         -> sample matlab scripts can be found in MITgcm_contrib/gael
294         that allow you to prepare netcdf input files.
295     - also modified: cleaner include statements, cleaner error print statements,
296       cleaner stops when error, and more tests of the netcdf input files consistency.
297    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
298    o pkg/seaice:
299     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
300       requires a new routine: seaice_diagnostics_fill.F
301     - make sure that seaice does not move if not forced (pressure replacement
302       method, Hibler and Ip, 1995), changes results
303     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
304     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
305       It is turned off by default (=-1.), because it changes the results.
306     - make it possible to read AREA from a file, too.
307    
308    checkpoint59c
309    o add S/R and diagnostics for oceanic mixed-layer depth
310    o move GMRedi call after all vertical mixing schemes (including KPP)
311    o pkg/thsice:
312     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
313      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
314    o pkg/obcs:
315     - bug fix for balance code
316    o pkg/seaice:
317      - allow values of SEAICE_elasticParm > 1
318      - add new parameter SEAICE_evpTauRelax as an alternative
319        to SEAICE_elasticParm
320      - make lsr boundary conditions free slip (by default), changes result
321      - add code for no slip boundary conditions for lsr
322      - set minimum of zeta to zero (and not 4e8) (changes results)
323      - add a cap on AREA after advecting AREA if seaice_growth is not called
324    o change calculation of Visbeck K:
325      - no longer depend on tapering scheme; instead, compute slope (limited
326        by GM_maxSlope). this is equivalent to what was comuted before with
327        clipping or linear tappering.
328      - fix vertical averaging (wrong by 1/2 level)
329      - leave the old version (but will not be maintained) within
330        #ifdef OLD_VISBECK_CALC / #endif
331      - update output of exp. ideal_2D_oce
332    o change error catch in calc_r_star to improve vectorization
333    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
334      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
335    o adjoint:
336      Re-organized adjoint checkpointing according to Matt Mazloff
337      (but with modifs/completions/cleanups)
338      Storing is now bundled into large arrays to optimized I/O
339      (and second step in cleanup of the_main_loop)
340    
341    checkpoint59b
342    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
343      - export/import (between ocean & coupler) fields needed for ocean DIC.
344    o pkg/seaice:
345      - get rid of three more exchanges seaice_calc_viscosities (required
346        different loop boundaries in seaice_lsr and seaice_ocean_stress)
347      - bug fix in seaice_ocean_stress (update of lab_sea required)
348      - reduce loop boundaries to necessary minimum also in seaice_evp
349      - go back to the old way of computing deltaC/Z as the adjoint likes that
350        better
351    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
352      passive tracer to an Age Tracer) + update output.txt
353    o pkg/exf:
354      - implement A-grid / C-grid selection for wind-stress input files.
355      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
356      for now, in exf_bulk_largeyeager04.F only :
357      - change implementation for case where windspeed + 2. components wind-stress
358        are read-in. AND use rhoConstFresh to convert evap.
359    o pkg/seaice:
360      - use correct EXCH_UV for wind-forcing (on A-grid).
361      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
362        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
363    o pkg/exf:
364      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
365      EXF_INTERPOLATION:
366      - merge global_with_exf/code version of exf_interp_read.F
367        to the main code ;
368      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
369        reading the file ; Important: This options needs to be defined to recover
370        previous code.
371        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
372      - no longer loose real*8 precision along the way when using exf_iprec=64.
373    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
374      - change discretisation of evp-solver in order to avoid another exchange
375        (changes lab_sea) and clean up a little
376      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
377        help the adjoint (this also changes the results slightly)
378      - add a few "_d 0" where they had been missing in seaice_evp.F
379      - cleaning up: remove unused seaice_calc_rhs.F
380    o pkg/exf: some cleaning-up:
381      - change various "constants" into runtime parameters
382      - cleaned-up Large&Yeager04 routine which should eventually
383        replace exf_bulkformulae.F (changed names of S/R and CPP)
384        and merged various ALLOW_ATM_WIND options
385     only used with thsice pkg (in thsice_get_exf.F):
386      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
387        which are used when useStabilityFct_overIce=TRUE (= the default)
388      - change default values of ice & snow emissivity and scale downward LW
389        by ice & snow emissivity.
390    o pkg/thsice:
391     fix few little problems, in thsice_calc_thickn.F:
392      - growth vertically (and not laterally) if iceFrac == iceMaskMax
393      - melt only laterally if hIce < hThinIce (as the comments say)
394      and in thsice_extend.F:
395      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
396      - start to form ice as soon as the minimum ice-volume is reachable.
397     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
398      and cpl_aim+ocn
399    o pkg/kpp
400     - move computation of surface related input fields to KPP into a new
401       subroutine kpp_forcing_surf.F
402     - remove wrong (within bi,bj loops) EXCH calls.
403     - little cleaning (add argument myThid in last position, cvs header ...)
404     - for now, fix conservation problem by exchanging KPPviscAz (may not
405       be the best fix)
406    o pkg/seaice
407     - check for inconsistent evp parameter/cpp-flag combination
408     - remove leftover errIO flat for obsolete name list error handling
409    o OpenAD
410     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
411    
412    checkpoint59a
413    o pkg/seaice: some parameter clarifications and a little bit of clean up
414    o pkg/thsice: rename run-time parameters:
415       himin       -> hIceMin
416       himin0      -> hThinIce
417       hihig       -> hThickIce
418       i0          -> i0swFrac
419       transCoef   -> bMeltCoef
420       frac_energy -> fracMelting
421      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
422       with default values (for now) that do not change the results.
423      remove old version of thsice vars advection in pkg/seaice.
424    o in FFIELDS.h:
425      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
426      - make pLoad & sIceLoad always available (but still only used if
427         ATMOSPHERIC_LOADING is #define).
428    o pkg/kpp: replaced _KPP_RL with _RL
429    o bug fixes for vertical diffusivity computations when both KPP and
430        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
431        are no longer updating the vertical diffusivity array
432        (passed as argument) but are (re-) setting those arrays.
433    o pkg/seaice: fix bug in evp solver, while doing that
434      - change (improve?) discretization of stress computations for both
435        cgrid-lsr and evp solver
436      - add a new routine to compute strain rates
437      - the above changes lab_sea results
438      - add no slip conditions for evp solver (off by default), lsr-version
439        may follow
440      - fix exchange for shear at Z-points (does not change lab_sea)
441      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
442        (to force the user to pick a time step since there is not "safe" way
443        of choosing it)
444      - add principal stress diagnostics
445      - rearrange fields for evp a little to avoid having to call a: too many
446        exchanges and b: exchanges for stress trensor components which we do
447        not have.
448      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
449        of evp, complete rewrite for lsr case (latter is does not yet work
450        in all cases)
451    o pkg/kpp: add code to have mixing in shelf ice caverns
452      - add myThid to all kpp routines (long overdue)
453    
454    checkpoint59
455    o pkg/exf:
456      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
457        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
458      - move exf header files from lower_case.h to UPPER_CASE.h ;
459        add missing cvs Header & Name
460      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
461      - add namelist param. selectStressGridPosition, exf_monFreq
462      - retire many _CLIM routines, and remove data.exf_clim
463        + params moved to data.exf
464        + climsst, climsss now handled by exf_set_gen, i.e.
465          climss?period=0 refers to constant field,
466          climss?period=-12 to monthly forcing
467      - split up namelists in data.exf
468    o pkg/seaice:
469      - remove seaice_exch and seaice_exch_uv
470      - remove superfluous exchange of theta
471      - add myThid to seaice_budget_ocean/ice
472      - add new interface for atmospheric wind forcing (C-grid only)
473        + new routine
474        + two new field (taux, tauy for stress over ice)
475        + removed one global field (DAIRN) for C-grid case only
476    o pkg/thsise
477      - 2nd set of modifs for thsice adjoint in conjunction with exf
478    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
479    
480    checkpoint58y_post
481    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
482      vertical diffusivity, similar to that in MOM4; turned on using
483      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
484      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
485    o Added capability for 3D specification of background vertical diffusion
486      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
487      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
488      "data" file that contains the 3D vertical diffusivity coefficients.
489    o ice dynamics (pkg/seaice) with thsice thermodynamics:
490      - add code within pkg thsice to advect & diffuse sea-ice fields
491      similar to (and will replace) what has been added in  seaice_advdiff.F,
492      but: - conserving Mass, Heat & Salt.
493           - better when using non-linear advection scheme (not yet fully tested)
494           - can also be used in atmospheric set-up (for now, only the diffusion).
495    
496    checkpoint58x_post
497    o IO option for global-file compact format:
498      - add options when generating topology (utils/exch2/matlab-topology-generator)
499      - add I/O capability (pkg/mdsio).
500      - adapt utils/matlab/rdmds.m to read this format.
501      for now long-line format not yet supported by pkg/mdsio (& exch2).
502    o shelfice: add a few diagnostics
503    
504    checkpoint58w_post
505    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
506      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
507      (and replace horiVertRatio in NH code).
508      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
509                         and tutorial_plume_on_slope (sensitive to truncation)
510    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
511      directly to drive seaice model (C-grid only)
512    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
513     - reintroduce computation of wind from stress,
514     - compute tau (in exf_bulkformulae.F) from windstress averaged to
515       mass points to avoid tau = 0
516     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
517    o rdmnc.m: make it work with "global" files created with gluemnc
518    o rdmnc.m : some improvements in dealing with singleton dimension
519      (tested on all testreport mnc output files).
520    o genmake2: disable pkg/profiles if netcdf test fails.
521    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
522    o move call to cal_readparms up to make calendar parameters/variable available
523      to all packages
524    
525    checkpoint58v_post
526    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
527      useDynP_inEos_Zc tested.
528    o pkg/exf: changes to properly interpolate/mask/scale initial fields
529    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
530      and portions thereof.  See read_cs.txt for description and examples.
531    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
532      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
533      following the great-circle arc between those 2 points.
534    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
535      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
536    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
537     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
538     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
539     - still needs work (not working with some options ; efficiency to improve)
540       and serious testing.
541     - use this scheme for temperature & salinity in 2 advection test exp.:
542       advect_xy & advect_xz, respectively.
543    
544    checkpoint58u_post
545    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
546    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
547    o testreport: add option "-skipdir" to skip some test.
548    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
549      momentum calculation.
550    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
551    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
552      remove checkpoint.F and the_correction_step.F (no longer used);
553      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
554    o add option (linFSConserveTr) to correct for tracer source/sink due to
555      Linear Free surface
556    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
557    o pkg/thsice: fix reading mnc-pickups
558    
559    checkpoint58t_post
560    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
561    o pkg/mdsio:
562     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
563       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
564       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
565     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
566     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
567       either MDS_READ_FIELD or MDS_WRITE_FIELD )
568     - new S/R (to replace MDSWRITEMETA), which allows to write more
569       informations (variable names, time ...) to meta files.
570     - modify rdmds.m to give back the meta file content.
571    o pkg/diagnostics: change vertical interpolation to be safer, and more
572       flexible (define p-levels to interpolate to in data.diagnostics);
573      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
574       diagnostic pointer.
575    o pkg/seaice: more cleaning up of seaice_growth, added many comments
576    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
577    o fix multi-category seaice:
578     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
579       SEAICE_MULTICATEGORY
580     - fix short wave heat flux
581    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
582       and allow to use EVP solver. Change forward lab_sea: test both EVP
583       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
584    o Initial check-in of lab_sea adjoint
585      (very similar to natl_box_adjoint/code_seaice)
586      * used C-grid and EVP solver
587      * used KPP, GM/Redi
588      * uses inAdExact=.TRUE.
589      * gradient checks fail for both ADM and TLM
590        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
591        f.d. gradients actually seem more problematic than ADM, TLM gradients;
592        issue is related to forward mismatch between g77 an ifort
593    o pkg/seaice: overhaul of thermodynamics
594     - growth.F and groatb.F are replaced by new routine seaice_growth.F
595     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
596     - move a few global fields out of SEAICE.h into seaice_growth.F and
597       make them 2D (FICE/QNETO/ ...)
598     - remove FO (it is the same as QNETO)
599     - introduce a few local fields to avoid modifying external fields such
600       as atemp, etc.
601    
602    checkpoint58s_post
603    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
604      changed exf_set_gen.F so that
605        genperiod=0 means input file is one time-constant field and
606        genperiod=-12 means input file contains 12 monthly means
607    o CG2D: use pre-computed solver main-diagonal (stored in common block);
608      this affects truncation error ; generate new output file for exp. which
609      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
610        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
611        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
612        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
613        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
614        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
615    o start implementation of deep-atmosphere and anelastic formulation
616    o verification: remove 2nd copy of input files and use script "prepare_run"
617      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
618    o mom_common/vecinv/fluxform: fix a few initialisation isssues
619    o profiles: fix for multithreaded case
620    
621    o diagnostics: rename few diags:
622      s/'PRESSURE'/'RCENTER '/g
623      s/'TICE    '/'oceFreez'/g
624      s/'TAUX    '/'oceTAUX '/g
625      s/'TAUY    '/'oceTAUY '/g
626      s/'SWFLUX  '/'oceQsw  '/g
627      s/DIFx/DFxE/g
628      s/DIFy/DFyE/g
629      and add few ocean-forcing diagnostics:
630      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
631    o modifications to pkg/seaice/growth.F and budget.F, which change results of
632      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
633      as actual snow thickness.  It now refers everywhere to effective snow
634      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
635    
636    checkpoint58r_post
637    o modifications to pkg/seaice/growth.F, which change results of
638      lab_sea experiment: fixes pertain to melting snow over open water, to
639      masking EVAP under sea ice, and to using the correct AREA variable for
640      computations of EVAP, PRECIP, HSNOW, and GHEFF
641    o add ability to read bathy, salt, and theta using MNC (off by def)
642    o add flooding algorithm and advection of HSNOW for pkg/seaice;
643      both are turned off by default and do no change any results
644    o seaice advection with pkg/thsice: a step toward the use of non-linear
645      advection scheme, but #ifdef or commented out for now (requires more EXCH).
646    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
647      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
648      in natl_box (affects results @ truncation level: update output.txt)
649    o multi-threading and IO:
650      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
651      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
652        (needed to work with SingleCpuIO): tested in all verif. exp.
653    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
654      affects the results (but none of the verification test uses this scheme).
655    o Adding some pkg/diagnostics capability to pkg/seaice
656      (will certainly be subject to changes)
657    o ctrl: adding new control variables:
658      lwflux, lwdown, evap, snowprecip, apressure, runoff
659    
660    checkpoint58q_post
661    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
662      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
663      high_res_cube configuration by 4% on Columbia.
664    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
665      add (in global_with_exf/code) a version of EXF_INTERP_READ without
666      dynamical allocation (seems to work in multi-threaded).
667    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
668      single CPU io) so that TAF does not have to see EESUPPORT.h
669    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
670    
671    checkpoint58p_post
672    o obcs: stop if obcs is used with useCDscheme = .true.
673    o shelfice:
674     - fix a sign error so that no slip at shelfice interface works
675     - remove stop for combination non-hydrostatic code and shelfice. That does
676       not mean, that the results are correct, but at least they are numerically
677       stable
678    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
679    o added adjoint exch routined for all exch*3d* routines
680      and updated flow directives
681    
682    checkpoint58o_post
683    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
684      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
685    o change controling S/R for writing pickup file (new S/R do_write_pickup)
686      and clean-up reading/writing of pickup files.
687    o fix local version of read/write pickup (NH part) in rotating_tank/code
688    o simplify EXCH interface:
689     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
690     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
691    o added the regrid package
692    o shelfice:
693     - add a simple boundary layer scheme to reduce noise
694     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
695    
696    checkpoint58n_post
697    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
698       local variable (not in common block).
699    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
700      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
701      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
702        to work with SingleCpuIO.
703    o add "_d 0" to real constant of pkg/cfc subroutines ;
704       update exp. cfc_exemple & tutorial_cfc_offline output files.
705    o multi-threading and IO:
706      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
707        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
708      - barrier before and after reading.
709      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
710      - avoid using MDS_WRITELOCAL for LAND pkg output.
711      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
712        common-block variables ; Allows multi-threading with master-thread IO.
713    o change default MAX_NO_THREADS from 32 to 4 ;
714      and stop cleanly when MAX_NO_THREADS is too small.
715    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
716    
717    checkpoint58m_post
718    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
719       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
720    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
721       keep global_ocean.90x40x15 (for AD testing) with former secondary test
722       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
723    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
724        add MITgcm_tutorials (= code + all the tutorials)
725    o ecco, option to compute cost for total ssh (mean+anom)
726    o consistent with addition of ptracer and ssh in pkg/profiles
727    o profiles: adding ptracer and ssh
728    o testreport: change multi-test output-file name
729      (from output.txt.{name} to output.{name}.txt)
730    o profiles: now ok for mutli-tiles case
731    o seaice: add 4 parameters for different advection schemes for area,
732      (effective) seaice thickness, enthalphy, and snow height. Their default
733      is the standard parameter SEAICEadvScheme
734    o calc_gw:
735     - add cosFacU in zonal viscous flux (harmonic.visc.).
736     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
737       of tutorial_plume_on_slope.
738    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
739    o calc_gw: true flux-form, account for horizontal grid spacing.
740      update rotating_tank results, but not plume_on_slope (affected at
741      truncation level, 11 digits).
742    
743    checkpoint58l_post
744    o calc_gw:
745     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
746     - remove side-drag for now (need to fix it); update plume_on_slope results.
747     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
748    o commit code to make SST/SSS weights spatially variable
749      (based on either variable in-situ or variable initial T/S weights)
750    o pkg/ecco:
751      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
752        now based on horizontally varying weights wthetaLev, wsaltLev
753      * cost_averagesflags now returns year indices in addition to day, month
754      * sflux balance is performed on annual basis
755        (sflxumm, sfluxmm2, bal_sfluxmm)
756      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
757        including separate counting and multipliers
758    o pkg/rbcs
759      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
760    
761    checkpoint58k_post
762    o testreport:
763     - always build in dir. "build" (if not there, mkdir build instead of building
764       & running in input)
765     - run in dir run (if it exists), in build otherwise.
766     - call prepare_run (if input/prepare_run exists)
767     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
768    o pkg/exf modifications to interpolation and rotation routines for more
769       reasonable treatment of North Pole singularity: for tracers North Pole
770       value is set to northernmost zonal-mean value, for zonal velocity it is
771       set to zero, and for meridional velocity it is set to northernmost value.
772    o pkg/exf/exf_check_range.F
773     - add tile index to diagnostics and move stop statement to the very
774       end of the routine.
775    o pkg/diagnostics: (diagnostics_main_init.F)
776      define title of isomorphic variables according to the current config.
777    o pkg/thsice with pkg/seaice dynamics:
778    - fix domain of computation (interior only, required for exf) and do exchanges
779    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
780    o towards a standard way of dealing with multi-threading in MONITOR
781      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
782    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
783       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
784    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
785    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
786    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
787       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
788    o tracer advection:
789     - clean-up and simplify calc_common_factors.F
790     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
791       advection subroutine (but still not used within DST advection S/R)
792    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
793    
794    checkpoint58j_post
795    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
796      from file (collects calls previously in FORWARD_STEP)
797    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
798    o adjoint store dir. adjusted accordingly
799    o genmake2
800      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
801    
802    checkpoint58i_post
803    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
804      on wind stress (SEAICEstressFactor defaults to 1.)
805    o Total number of Timers is finite (<=40): comment out 2 non-essential one
806      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
807    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
808      on CS-grid: no longer loosing mass.
809    o exf & curvilinear-grid: no longer modify longitude xC & xG.
810    o pkg/ggl90: fix sloppy output and fix a bug
811    o pkg/seaice: added SEAICEuseEVPpickup parameter
812      - Set to false in order to start EVP solver with
813        non-EVP pickup files when using SEAICEuseEVP
814      - fix sign error in diffusion in seaice_calc_rhs
815    
816    checkpoint58h_post
817    * Modifications for bottom topography control
818      o replace hFacC by _hFacC at various places
819      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
820      o add non-self-adjoint cg2d_nsa
821      o update autodiff support routines
822      o re-initialise hfac after ctrl_depth_ini
823      o works for 5x5 box, doesnt work for global_ocean.90x40x15
824    * Adding verification for 5x5 box (4-layer) bottom topography control
825    
826    checkpoint58g_post
827    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
828       used for mean seasonal cycle, mean diurnal cycle); add an example
829       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
830    o pkg/ggl90:
831      - add parameter (minimum surface kinetic energy)
832      - fix bug (avoiding division by zero)
833    o couple pkg/thsice to pkg/seaice:
834      - modify advection in seaice to accomodate new scalar fields to be advected
835      - only muliDimAdection scheme work with seaice/thsice
836      - mapping of thsice-variables to seaice-variables, back and forth
837      - does not break the verification experiments, but does not give the
838        desired results either
839    o pkg/seaice
840      - make (default) second order advection a bit less confusing?
841    
842    checkpoint58f_post
843    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
844      to pkg/seaice):
845      - new routines thsice_map_exf and thsice_get_exf provide the interface
846      - add an additional formal parameter to thsice_solve4temp
847    o pkg/exf:
848      - add new fields wspeed, snowprecip (to be able to couple to thsice)
849      - correct Stefan-Boltzmann constant
850      - new parameter for longwave surface emittance
851      - separate some stuff from exf_bulkformulae into new routines  
852        exf_radiation, exf_wind
853      - add new parameters and constants: longwave emissivity for ocean, ice
854        and snow, evaporation parameters over ice
855      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
856        either wind from stress or stress from wind
857    o pkg/thSIce:
858    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
859    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
860       and THSICE_CALC_THICKN
861    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
862    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
863      to make debugging easier.
864    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
865    o pkg/bulk_force:
866      - clean-up comments and parameters ;
867      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
868    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
869      generate new output for test-experiment: aim.5l_cs.thSI
870    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
871      testreport accordingly
872    
873    checkpoint58e_post
874    o SEAICE_CGRID adjoint done
875    o R_STAR adjoint implemented.
876      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
877      * need to sort out init. of h0facc, etc.
878    o Make pkg/profile fully independent of ecco,cost, etc. stuff
879      to be able to use it in pure forward.
880    
881    checkpoint58d_post
882    o upgrade simple test-experiment to tutorial example:
883     step.1: duplicate the experiment and (step.2) will remove the old copy.
884      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
885      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
886      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
887      tutorial_global_oce_biogeo    <- copy of dic_example
888      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
889      tutorial_plume_on_slope       <- copy of plume_on_slope
890      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
891      tutorial_global_oce_optim     <- empty for now (David ?)
892      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
893     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
894    o correct a sign problem in cost_scat.F
895    o obcs and ptracers: fix boundary conditions for advections schemes
896      with larger stencil
897    o thsice adjoint: start
898    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
899      completeness
900    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
901      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
902    o ptracers adjoint:
903      * avoid extensive recomputatations
904      * fix missing re-init. of gptr (missed by TAF)
905    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
906      me to turn off the excessive output to STDOUT that this package produces
907    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
908      and add those terms in Vector-Invariant formulation.
909    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
910      if the control period (xx_hfluxperiod etc) is 0
911    o in profiles pkg, clean routines and fix details
912    o in ecco pkg, reading ssh data:
913      fix problem in case the model does not start at iter0=0
914    o fix mnc-pickup/restart for ptracers
915    o new package prifiles:
916      code to compute profile-based cost by Gael Forget
917      (modifs in ecco, ctrl, autodiff)
918    o Benign bug fix in initialization (spotted by M. Mazloff) of
919      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
920    
921    checkpoint58c_post
922    o adjoint: finish NLFS adjoint and provide reference output in
923      verification/global_ocean.90x40x15/results_ad_nlfs
924    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
925      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
926      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
927      with SEAICE_CGRID defined.
928    o move calendarDumps from "data" to "data.cal" and clean-up the code
929      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
930    o add useEXF & useCAL flags (for now, set in hard-coded way)
931    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
932      (were missing in NH mode, and wrong in quasihydrostatic mode).
933      waiting for Chris updated version of calc_gw to add those CALLs.
934    o fix bug in quasihydrostatic S/R ;
935      add a test for this option: global_ocean.90x40x15.qshyd
936    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
937      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
938    o add on/off flag useOffLine for package OFFLINE
939    o seaice:
940      - modify advection so that it works also on the C-grid
941      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
942        problem in multi-tile runs with C-grid
943      - add flags for clipping ice velocities and/or masking solver forcing
944      - fix drag (ocean on ice) formulation and a bug that caused noise in the
945        C-grid solver
946      - added a few comments to seaice_diffusion.F
947      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
948        are now exclusive)
949      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
950        required re-ordering the code a little:
951       + make DAIRN global variable (defined in SEAICE)
952       + move computation of the viscosities eta and zeta into a new separate
953         routine (because I need to recompute them in seaice_ocean_stress.F)
954    
955    checkpoint58b_post
956    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
957      update output.txt of exp. aim.5l_cs.thSI
958    o various mnc cleanups and improvements:
959      + shrink lookup tables by factor of ~4
960      + better error reporting when running out of lookup space
961      + able to handle longer path/file names (up to 500 chars)
962    o adjoint:
963      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
964      - TBD: "hidden" mom_vecinv recomp. in dynamics
965    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
966     (allow to differentiate between forcing components using new integer flags:
967      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
968     and add new flag to put Dissipation tendency out of Adams-Bashforth.
969    o ecco
970      - enable trend removal from SSH anomaly obs.
971    o adjoint
972      - a fix for PmEpR when #undef EXACT_CONSERV
973      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
974      - try to fix "hidden" recomp. in forward_step for NLFS
975        (NLFS seems broken sometimes after I checked it in)
976    o seaice:
977     - add c-grid version of the dynamic solver:
978       + three new routines that are the c-grid substitute lsr, dynsolver
979         and ostres
980       + put a few fields that were local to dynsolver into global common
981         blocks, so that I can move the computation of stresses etc into
982         seaice_lsr (saves coding but may break the adjoint).
983     - replace more hardwired parameters by runtime parameters
984     - add ice masks that mask the rhs of the implicit solvers where there
985       is no ice (commented out in seaice_dynsolver, because i am not sure
986       if this works properly), eventually this should replace the clipping
987       of ice velocities in seaice_dynsolver to +/-40cm/s.
988    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
989      include it only where its needed
990    o move balancing of fluxes before the call of external_forcing_surf
991    o seaice:
992      - correct units of turning angles (now they are really in degrees)
993      - move computation of GWATX/Y out of main routine into dynsolver
994      - initialize GWATX/Y in seaice_init
995    o Apply mask on Fresh-Water flux (needed for SSH forcing).
996      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
997    o seaice: add runtime flags for turning angles (default to zero)
998    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
999      and trend from exf forcing and ctrl control adjustments
1000    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1001      (since checkpoint57x_post)
1002    o change the default rotation period to 86164.s = the Earth rotation
1003    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1004      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1005    o seaice advection: add code for choosing between the default (2nd order
1006      central differences) and multiDim advection schemes provided by
1007      pkg/generic_advdiff
1008    o seaice:
1009      - removed all references to SEAICE_GRID.h fields from
1010        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1011        (cubed-sphere configuration will change a little)
1012      - grid computations in seaice_init are obsolete now.
1013      - cleaned up code a little so that is easier to read (hopefully).
1014      - added new (better?) discretizations of default advection and diffusion
1015        (turn on with SEAICEuseFluxForm)
1016      - replace 1 in 3d global fields by kSurface in growth.F
1017      
1018    checkpoint58a_post
1019    o seaice:
1020      - bug fix in advect.F
1021    o shelfice:
1022      - separate shelfice load anomaly from pload (breaks with time
1023        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1024        Its default is 0., but it may be computed more cleverly from (unknown)
1025        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1026        done offline. A good approximation of the pressure load anomaly is
1027        necessary to avoid large initial adjustment processes underneath
1028        deep-reaching shelfice.
1029      - small fix in ISOMIP shelfice_thermodynamics
1030      - add more sophisticated thermodynamics of Hellmer (1989), this is
1031        now the default
1032      - give a few constants more intuitive names
1033    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1034      if bulk formulae are used in long integration (especially EmPmR). Turn
1035      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1036      if balancePrintMean, the imbalance that is substracted is printed to
1037      STDOUT.
1038    o fix bug (typo) in obcs_apply_eta.F
1039    o add a new package shelfice which enables us to model the circulation
1040      underneath shelf-ice with draughts of hundreds of meters.
1041     - works
1042     - to do: + include improved thermodynamics
1043              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1044                instead of new field kTopC
1045              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1046                instead of new field R_shelfIce and new code in ini_depth.F
1047                and ini_mask_etc.F?
1048              + adjust vertical mixing schemes?
1049    o seaice pkg:
1050     - add a cpp-flag to include a simple formula for a salinity dependent
1051       freezing point of sea water at the surface
1052     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1053       meridional stresses are now different (and hopefully correct)
1054    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1055       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1056       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1057    o pkg/diagnostics: add options and parameters for regional-statistics
1058       diagnostics ; define regions by reading a region-mask from a file
1059       (might add other options later)
1060    o pkg/bulk_force:
1061     - add option and parameters to use AIM surface-flux formulae.
1062     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1063       others forcing fields (defined in PARM05, parameter file "data") are loaded
1064       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1065     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1066     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1067     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1068       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1069     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1070    
1071    checkpoint58
1072    o add "--embed-source" option to genmake2 which, when the supporting
1073      tools can be compiled (as determined by genmake2) will turn on the
1074      embed_files package which then embeds the entire MITgcm source code
1075      (*.[fFhc] + Makefile) used for the build within the executable
1076      - requested by CNH but off by default
1077      - adds a paltry <9MB to the mitgcmuv executable in most cases
1078      - only writes the output when useEMBEDSRC in eedata is true
1079    o clean up 3-dim. relaxation codes:
1080      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1081      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1082      * Thanks to Tom Haine for testing!
1083    
1084    checkpoint57z_post
1085    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1086      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1087    o fix the pickup behavior for obcs in combination with ptracers
1088    o fix a bug in ptracers_external_fields_load
1089    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1090      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1091    o transfered surface NH pressure to eta field (if exactConserv).
1092    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1093         and update lab_sea output.txt file.
1094    o completing 3-dim. relaxation code: additional term
1095         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1096      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1097      * At compile time, in "EXF_OPTIONS.h" set
1098          #define  ALLOW_CLIMTEMP_RELAXATION
1099          #define  ALLOW_CLIMSALT_RELAXATION
1100      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1101          tauThetaClimRelax3Dim = 15552000.0,
1102          tauSaltClimRelax3Dim  = 15552000.0,
1103      * 3 cases:
1104          1) Use a constant-in-time 3-dim. field
1105          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1106          3) Real-time relax. to time-evolving prescribed field
1107    o Adding Laplacian-type smoothness constraint on
1108      initial and boundary (forcing) controls (ic, bc)
1109      * enable at compile-time via
1110        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1111      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1112      * Absolute scale somewhat unclear so far
1113      * no area weighting was included since no other cost term does so far
1114    
1115    checkpoint57y_post
1116    First step for a NLFS adjoint
1117    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1118    o new init. routines for calc_r_star, calc_surf_dr
1119    o still need to deal with ini_masks_etc
1120    o testreport seemed happy
1121    checkpoint57y_pre
1122    
1123    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1124    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1125    o add new offset feature to offline pkg (plus minor cleanup)
1126    o cfc fixes for final year of integration
1127    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1128      be in GCHEM_OPTIONS).
1129    
1130    checkpoint57x_post
1131    o fix testreport Pb in multiple test experiment.
1132    o cleanup our namelist syntax in verification:
1133      - make it more F95 standards compliant (some work still needed)
1134      - allows the vast majority of our tests to work with gfortran
1135    o Non-Hydrostatic:
1136     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1137     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1138    o Allow to apply AB on T,S rather than on AB(gT,gS):
1139     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1140     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1141       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1142     - need a "clever" read_pickup to restart from the other AB formulation
1143    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1144    o remove some unused variables (reduces number of compiler warnings)
1145    o adjoint
1146      * Disable useVariableViscosity for adjoint for time being
1147        (there are a number of extensive recomputations)
1148      * Initialize certain variables needed for adjoint
1149    
1150    checkpoint57w_post
1151    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1152                 fix the singleCpuIO RS version of MDSWRITEFIELD
1153       and add a WARNING if using globalFiles=T with multi-processors.
1154    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1155      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1156    o tracer advection scheme:
1157      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1158       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1159       was not very convenient).
1160      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1161       (further tests needed for the implicit DST & Flux-Limiter schemes).
1162    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1163      and sRef for convenience, handy, when you want to initialize
1164      ptracers in a large domain with a constant non-zero value. Also,
1165      untangle ptracers_init.F a little.
1166    
1167    checkpoint57v_post
1168    o change dome exp. to use variable viscosity in side-drag terms.
1169    o remove all the files from the cfc_offline test since they are now
1170      incorporated into tutorial_cfc_offline which has been producing
1171      identical results for a few days of testing
1172    o add new parameter: sideDragFactor to enable half-slip-side BC
1173      and change side-drag S/R to use viscosity from mom_calc_visc
1174      (can switch back by setting sideDragFactor=0.); affects results at
1175      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1176       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1177    o vorticity & strain are now computed without masking, to account for
1178      no-slip-side BC in variable viscosity calculation ; mask is applied
1179      anyway later on, before computing advection/coriolis terms.
1180    o modify exp4 to test new obcs support for reading from external files
1181      and for passive tracers
1182    o fix behavior of ptracers_monitor when monitor output is written to a
1183      netcdf-file; still not independent of monitor.F (writes in the same
1184      file).
1185    o change default value of tRef (put a uniform, meaningful value for ocean
1186      & atmos) and initialize sRef (was missing, as Martin mentioned).
1187    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1188      to be proportional to enstrophy dissipation length.  Thus,
1189       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1190      This is now consistent with Smagorinsky and with the manual.
1191    
1192    checkpoint57u_post
1193    o OBCS and PTRACERS: add open boundary support for passive tracers
1194      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1195        OB-values from file; this is not different from the way theta and salinity
1196        are treated
1197      - however, Orlanski-radiation conditions are not supported, and the model
1198        will stop if you use pTracers and Orlanski at the same time.
1199      - beefed up the rountine obcs_external_fields_load: now only those open
1200        boundary values are overwritten with values from files for which there
1201        are really files, otherwise the OB-fields remain untouched. This makes
1202        it possible to use different OBs at different ends of the domain (as
1203        with EXF)
1204    o reduce number of exch calls in shap_filt (s2).
1205    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1206      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1207    
1208    checkpoint57t_post
1209    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1210    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1211      same truncation, independent of the face number: affects affects several
1212      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1213    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1214      note that biharmonic viscosity + no-slip was not tested in any experiment.
1215    o fix bug in non-linear free-surf side-drag ; generate new output for
1216      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1217    o make mnc honor the writeBinaryPrec flag for most kinds of output
1218    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1219    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1220      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1221    o add brackets in multi-terms sum to get same truncation, independent of
1222      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1223      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1224    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1225      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1226      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1227      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1228      Suggested values of viscosity parameters found in mom_calc_visc.
1229      Many new viscosity diagnostics available.
1230    
1231    checkpoint57s_post
1232    o Add clearing-house for viscosity calculations, mom_calc_visc and
1233      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1234      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1235      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1236      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1237      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1238      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1239      ViscAhStrain and viscAhTension are now retired.
1240    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1241    o In response to JMC's bug report, genmake2 now ignores any soft-links
1242      that it finds in the *current* directory when searching for files.
1243      Soft-links found in any other source directories will still work as
1244      they did before.
1245    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1246      a C routine to unlimit the stack size
1247    o mnc-ify pkg/aim snapshot vars
1248    o mnc-ify pkg/land as requested by Daniel
1249    o various changes to mnc including:
1250      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1251      - output can now be grouped so that all files within a group
1252          change the ITER portion of their names in lock-step together
1253      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1254          and works with both EXCH1 and EXCH2 (but needs more testing)
1255      - writing works for all verification test cases w/ g77 on Linux
1256    
1257    checkpoint57r_post
1258    o make MNC variable initialization happen earlier
1259    o add diagnostics for (almost) each term of the momentum Eq.
1260    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1261    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1262    o remove MINIMAL_TAVE_OUTPUT option ;
1263      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1264    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1265      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1266    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1267    o add time-dependent SST, SSS control
1268    o cost terms in ecco/ modularized (new cost_generic.F)
1269    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1270    o new infrastructure for seaice model vs. obs misfits in seaice/
1271      * driver from the_main_loop.F is seaice_cost_driver.F
1272      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1273      * gradient check in Exp. 6a of natl_box_adjoint/
1274    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1275      (see README file)
1276    
1277    checkpoint57q_post
1278    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1279    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1280      - bug was reported by Jean-Michel and Ian Fenty
1281    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1282      update exp. cpl_aim+ocn output.
1283    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1284      Needed for high-res. runs with large global files
1285      to be able to limit tapelev size
1286    o Changed some tests for adjoint:
1287      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1288      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1289      * global_ocean.90x40x15/ back to default 3-level checkpointing
1290    o Modifications to enable scripted COMMON to MODULE conversion
1291      * verification/OpenAD/code/ has necessary scripts and description;
1292      * converts, compiles and runs successfully;
1293    
1294    checkpoint57p_post
1295    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1296    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1297      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1298    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1299    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1300      (was already the case for dissipation with mom_vecinv,
1301       and also the case for grad.PhiHyd when staggered-timeStep)
1302      This will allow to put dissipation out-off the AB time-stepping.
1303     Unfortunately, affects truncation error. Update output of exp. that "fails"
1304      (cg2d matching number) and leave the others for later: front_relax(10),
1305      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1306      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1307    
1308    checkpoint57o_post
1309    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1310      (2) its ready to be documented during the 20050801 DocFest
1311    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1312      for ideal_2D_oce and lab_sea on linux_ia32_g77
1313    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1314      in global1x1_tot/code_seaice_adj to access indices 32, 33
1315      (worth another tag)
1316    
1317    checkpoint57n_post
1318    o adding precip control xx_precip 32
1319    o adding swflux control xx_swflux 33
1320    o Replacing 10 forcing penalty cost routines by 1 generic.
1321    o Implementing partitioning in time-mean and variable adjustment
1322      for atmos. state.
1323    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1324  o in natl_box_adjoint:  o in natl_box_adjoint:
1325    * updated: results_bulk/    * updated exp 1 to 10
1326    * not yet updated: results/, results_seaice/      (but does not have time-mean vs. variable split results yet)
1327    o updated global1x1/*_seaice_adj/
1328      to incorporate latest changes
1329    o enable useSingleCpuIO for mdsio vector routines
1330      (applies in particular to tapelev I/O)
1331    o removed inefficient K-loop in all active_file*control*.F
1332    
1333  checkpoint57m_post  checkpoint57m_post
1334  o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)  o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
