4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
8      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
9      for now this is only available for the C-grid code and also within
10      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
11    
12    checkpoint59m
13    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
14      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
15    o gad_som : fix flux output (& diagnostics) to have same units as other  
16      advection scheme fluxes (was previously multiplied by deltaT).  
17    o added verification/seaice_obcs both to test seaice open boundaries
18      and to provide an example matlab scrpt for generating them
19    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
20    o pkg/salt_plume: clean up salt_plume_frac.F to
21      remove redundancy in PlumeMethod 1 and 4
22    o pkg/kpp: added saltplume diagnostics
23    o pkg/obcs and pkg/seaice:
24      - do not set uice and vice to zero when OB*icefile are unspecified
25      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
26      - moved seaice tracer obcs after call to seaice_growth
27    o pkg/salt_plume: added various options for salt plume depth
28      criterion and for vertical distribution of the salt
29    
30    checkpoint59l
31    o pkg/ptracers: new version of ptracers pickup:
32      read meta file and write only fields which are needed to restart.
33      ( same logic as main pickup file ; also using pickupStrictlyMatch )
34    o pkg/seaice:
35      - add timescale for melting due to warm mixed layer as a means of
36        setting SEAICE_availHeatFrac more conveniently
37      - add a CPP-flag/runtime parameter check for flooding algorithm
38      - reformulated availHeat in seaice_growth.F to be independent of AREA
39    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
40      unit changes
41    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
42    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
43      SX vector computer.
44    o pkg/seaice:
45      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
46        seaice forcing fields can now be read only through pkg/exf
47      - removed some unused halos
48    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
49    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
50      or U/VICE from U/VWIND before computing U/VSTRESS
51    
52    checkpoint59k
53    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
54      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
55    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
56      all experiments pass when compile with un-initialised var. checking option.
57    o added pkg/salt_plume
58    o script to test restart (for now, in MITgcm_contrib/jmc_script)
59    o pkg/seaice: new read/write pickup version.
60      read meta file and write only fields which are needed to restart.
61      ( same logic as main pickup file ; also using pickupStrictlyMatch )
62    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
63    o lab_sea.hb87: modify the domain & update output.hb87.txt :
64      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
65      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
66      process. Fixed here by closing the domain at the Northern boundary.
67    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
68    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
69      a set of consecutive levels in/from a 3-D array.
70    o pkg/ptracers:
71      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
72      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
73    
74    checkpoint59j
75    o in pkgs: dic, obcs, offline, rbcs:
76      standard way to compute coeff. for time interpolation between 2 time reccords
77      which retains full precision (& make results less dependent on compiler).
78      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
79    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
80      packages instead of reading ice cover and wind speed separately
81    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
82     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
83      to allow to compile customized code before the update)
84    o cleaning-up:
85      - fix CPP instruction syntax in pkg/obcs
86      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
87        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
88      - fix some threads issue in IO parts.
89    o pkg/dic:
90      - add tons of "_d 0" (--> much better testreports !)
91       and then update outputs of tutorial_global_oce_biogeo
92    o pkg/mom_fluxform:
93      add a special version of momentum advection intended to conserve momentum
94      next to a bathymetry step or a coastline edge. (default = off = #undef)
95    o new read/write pickup version:
96      - for now, only implemented for main (mdsio) pickup file.
97      - write out only what is needed to restart; merge pickup_nh , pickup_ph
98        and main pickup together.
99      - read meta file; read only what is needed to restart; stop if a field
100        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
101        if it make sense (even if the restart is not perfect).
102      - if no meta file, assume that pickup to read corresponds exactly to
103        a pickup that would currently be written.
104      - read pickup written in the old format (until checkpoint59i) if it
105        recognizes an old meta file (no field-list).
106      - add a meta file in exp. which starts from a pickup: 2 cases:
107        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
108         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
109        b) a meta file describing the content of the associated pickup file
110         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
111    o pkg/mdsio & pkg/rw:
112      - new routine to read a meta file ; new set of routine to read
113        Multiple-fields file (with meta file).
114    o added open boundary conditions capability for seaice
115        HSNOW, HSALT, UICE, and VICE
116    
117    checkpoint59i
118    o adjoint:
119      * fix multiDimAdvection adjoint
120        (partial recomputation problem by TAF for fVerT(:,:,kDown)
121        and comlev1 size definition (maxpass vs. max. number of tracers)
122      * verification/global_ocean.90x45x15 adjoint now tests
123        NLFS and multiDimAdvection using DST3 (=30)
124      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
125    o pkg/kpp: add "_d 0" to real constant (if missing);
126      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
127      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
128    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
129      for internal parameters related to restart process (formerly from PARAMS.h)
130      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
131    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
132      as argument. (only atm2d & obcs write_pickup have not yet been updated)
133    o pkg/monitor:
134      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
135      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
136      - account for deep Atmosphere factor and density factor (anelastic)
137    o added open boundary conditions capability for seaice HEFF and AREA
138    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
139      thermodynamics
140      - requires a little reorganization, which affects the testreport results
141        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
142        so that now the conservative form is tested
143      - add a few comments
144    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
145    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
146    o add new diagnostics to seaice: advective, diffusive fluxes (only for
147      multidim-advection, for scheme 2 they are not filled) and transports,
148      thermodynamic growth rates
149    o change units of EmPmR (inside the code, + within coupling interface)
150      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
151      Affects results @ truncation level (cg2d match) and update output of
152       experiments: lab_sea(6), global_ocean.90x40x15(10),
153      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
154      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
155      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
156      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
157    
158    checkpoint59h
159    o pkg/exf:
160      - improve vectorization by moving if-statement out of loops in
161        exf_mapfields, exf_radiation
162      - exf_bulkformulae.F: introduce 2D fields and vectorize code
163    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
164    o testreport:
165      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
166        monitor & update offline_exf_seaice exp. output.
167      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
168    o pkg/seaice:
169      - bug fix in the evp solver: boundary conditions were affected be
170        masking of zMax/zMin (changes results)
171      - minor bug fix in boundary conditions in seaice_calc_strainrates
172        (changes results for no_slip)
173      - seaice_lsr.F: make interpolation of eta dependent on boundaries
174      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
175      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
176        stress formulation and no-slip boundary conditions
177    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
178      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
179    o pkg/seaice: a first HSALT time stepping equation has been checked in
180    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
181      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
182      without requiring DO-IF statements
183    o pkg/thsice:
184      use continuous power-law function for partition of energy between lateral
185      melting/freezing and thinning/thickening ; old code using step function
186      still available with #undef THSICE_FRACEN_POWERLAW
187      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
188    o testreport: change AD testing : check against results/output_adm.txt
189      using same scripts as for forward test.
190    
191    checkpoint59g
192    o adjoint testing: in preparation for changing testreport:
193      - output format: cost and grad written on separated lines
194      - ad output results in directory "results" (instead of "results_ad")
195    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
196    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
197    o pkg/ecco: allow user defined cost function contributions
198    o testreport:
199      Allow to choose (per experiment) the list of tested output variables
200       and the main variable (used to issue a pass/FAIL ) ;
201      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
202      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
203      Also modify printing of summary:
204       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
205       b) echo the list of tested variables in the individual summary.txt of
206          each experiment.
207    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
208      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
209      (but still depend on the tile decompostion of the domain).
210    o pkg/seaice: change a discretization detail to make the B-grid code
211      "more symmetric". This change is likely to remove all "ridges/leads" that
212      where quasi-aligned with the grid in B-grid solutions. It may also be
213      the solution to the stress coupling issues with the B-grid.
214    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
215      remove .cvsignore from input dir. (since testreport no longer run here).
216    o pkg/thsice:
217     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
218     - fix reshaping of sea-ice just after advection:
219       melt all the ice only if ice-volume is too small.
220     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
221       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
222     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
223    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
224      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
225    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
226      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
227      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
228      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
229      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
230      -> update output.txt
231    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
232     this affects truncation error: -> update output.txt of exp:
233      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
234      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
235    
236    checkpoint59f
237    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
238    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
239      a bounded range (in forward mode)
240    o pkg/ecco, ctrl, autodiff and mom_common:
241     internal parameter controls, completements of implementations
242    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
243    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
244      (not seem any difference in testing results).
245    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
246       at face corners.
247    o pkg/generic_advdiff:
248     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
249      loop range indices for computing vertical advection tendency
250      and do the calculation in the interior only (no overlap) ;
251      for now, only implemented for SOM advection (to save CPU time).
252     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
253    o exch2 adjoint
254      First set of changes:
255      - add exch2 hand-written adjoint templates
256      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
257        This will require cleanup in pkg/autodiff/*.F
258        (changed routines currently kept separate in verif. code/)
259      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
260        that used to hide exch2 or cubed-sphere specific code
261        (commented via 'cph-exch2')
262    o pkg/seaice
263      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
264    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
265       output of global_ocean.cs32x15.thsice .
266    
267    checkpoint59e
268    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
269      for B-grid vector (not yet tested) and C-grid vector (<- only used
270      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
271    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
272      (#ifdef ALLOW_SALT_PLUME)
273    o gather_2d/scatter_2d: removed halo regions
274    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
275      scheme and the corresponding test case (under front_relax dir). For now,
276      only available with Skew-flux form and not yet tested in realistic set-up.
277      adjoint: store directives updated, but gradient checks deteriorated,
278      so maybe GM/Redi adjoint is now broken.
279    o seaice adjoint
280      * add AREA, HEFF, HSNOW as control variable
281        (should not change lab_sea results)
282      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
283    o pkg/seaice:
284      * added computation of saltFlux in seaice_growth;
285        For time being, sea ice salinity is assumed constant
286        contribution of snow flooding to freshening of sea ice is neglected.
287        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
288        defaults to 0.0 in order to maintain backward compatibility.
289        Typical values for SEAICE_salinity are 4 to 10 g/kg.
290      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
291      * added SEAICE_availHeatFrac, which specifies fraction of surface level
292        heat content used to melt or grow ice
293      * commented out cap of HICE: it helps keep ice thinner
294      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
295      * applied OBCS T/S mask to HEFFM sea ice mask
296    
297    checkpoint59d
298    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
299     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
300     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
301    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
302     and change default value of parameter "GM_Small_Number";
303     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
304       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
305       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
306    o pkg/ecco: cost function when applying pkg/smooth to controls
307    o pkg/ctrl: add forcingPrecond run time parameter
308    o pkg/seaice:
309     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
310     - fix bug in metric terms of u-equation in LSR solver (implicit part),
311       changes verification/lab_sea
312     - rearrange implicit part of u-equation in LSR solver to make it easier to
313       read, understand, and debug. This causes changes at the truncation level.
314     - fix (serious) bug in the boundary conditions (sign error in the implicit
315       part) of the LSR solver. Changes all LSR results.
316     - fixed problem with HSNOW initialization to avoid thick snow when AREA
317       is initilized with small values - does not change lab_sea results.
318     - added HsnowFile initialization capability
319    o pkg/smooth: addition to model/src and pkg/ctrl so allow
320     initialization of pkg/smooth and application to control vector
321    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
322    o dependencies: pkg/profiles requires pkg/cal
323    o pkg/profiles:
324     - added option ALLOW_PROFILES_GENERICGRID
325         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
326         that interpolation information (grid points and coefficients) is provided
327         within the netcdf input files.
328         -> sample matlab scripts can be found in MITgcm_contrib/gael
329         that allow you to prepare netcdf input files.
330     - also modified: cleaner include statements, cleaner error print statements,
331       cleaner stops when error, and more tests of the netcdf input files consistency.
332    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
333    o pkg/seaice:
334     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
335       requires a new routine: seaice_diagnostics_fill.F
336     - make sure that seaice does not move if not forced (pressure replacement
337       method, Hibler and Ip, 1995), changes results
338     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
339     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
340       It is turned off by default (=-1.), because it changes the results.
341     - make it possible to read AREA from a file, too.
342    
343    checkpoint59c
344    o add S/R and diagnostics for oceanic mixed-layer depth
345    o move GMRedi call after all vertical mixing schemes (including KPP)
346    o pkg/thsice:
347     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
348      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
349    o pkg/obcs:
350     - bug fix for balance code
351    o pkg/seaice:
352      - allow values of SEAICE_elasticParm > 1
353      - add new parameter SEAICE_evpTauRelax as an alternative
354        to SEAICE_elasticParm
355      - make lsr boundary conditions free slip (by default), changes result
356      - add code for no slip boundary conditions for lsr
357      - set minimum of zeta to zero (and not 4e8) (changes results)
358      - add a cap on AREA after advecting AREA if seaice_growth is not called
359    o change calculation of Visbeck K:
360      - no longer depend on tapering scheme; instead, compute slope (limited
361        by GM_maxSlope). this is equivalent to what was comuted before with
362        clipping or linear tappering.
363      - fix vertical averaging (wrong by 1/2 level)
364      - leave the old version (but will not be maintained) within
365        #ifdef OLD_VISBECK_CALC / #endif
366      - update output of exp. ideal_2D_oce
367    o change error catch in calc_r_star to improve vectorization
368    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
369      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
370    o adjoint:
371      Re-organized adjoint checkpointing according to Matt Mazloff
372      (but with modifs/completions/cleanups)
373      Storing is now bundled into large arrays to optimized I/O
374      (and second step in cleanup of the_main_loop)
375    
376    checkpoint59b
377    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
378      - export/import (between ocean & coupler) fields needed for ocean DIC.
379    o pkg/seaice:
380      - get rid of three more exchanges seaice_calc_viscosities (required
381        different loop boundaries in seaice_lsr and seaice_ocean_stress)
382      - bug fix in seaice_ocean_stress (update of lab_sea required)
383      - reduce loop boundaries to necessary minimum also in seaice_evp
384      - go back to the old way of computing deltaC/Z as the adjoint likes that
385        better
386    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
387      passive tracer to an Age Tracer) + update output.txt
388    o pkg/exf:
389      - implement A-grid / C-grid selection for wind-stress input files.
390      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
391      for now, in exf_bulk_largeyeager04.F only :
392      - change implementation for case where windspeed + 2. components wind-stress
393        are read-in. AND use rhoConstFresh to convert evap.
394    o pkg/seaice:
395      - use correct EXCH_UV for wind-forcing (on A-grid).
396      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
397        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
398    o pkg/exf:
399      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
400      EXF_INTERPOLATION:
401      - merge global_with_exf/code version of exf_interp_read.F
402        to the main code ;
403      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
404        reading the file ; Important: This options needs to be defined to recover
405        previous code.
406        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
407      - no longer loose real*8 precision along the way when using exf_iprec=64.
408    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
409      - change discretisation of evp-solver in order to avoid another exchange
410        (changes lab_sea) and clean up a little
411      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
412        help the adjoint (this also changes the results slightly)
413      - add a few "_d 0" where they had been missing in seaice_evp.F
414      - cleaning up: remove unused seaice_calc_rhs.F
415    o pkg/exf: some cleaning-up:
416      - change various "constants" into runtime parameters
417      - cleaned-up Large&Yeager04 routine which should eventually
418        replace exf_bulkformulae.F (changed names of S/R and CPP)
419        and merged various ALLOW_ATM_WIND options
420     only used with thsice pkg (in thsice_get_exf.F):
421      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
422        which are used when useStabilityFct_overIce=TRUE (= the default)
423      - change default values of ice & snow emissivity and scale downward LW
424        by ice & snow emissivity.
425    o pkg/thsice:
426     fix few little problems, in thsice_calc_thickn.F:
427      - growth vertically (and not laterally) if iceFrac == iceMaskMax
428      - melt only laterally if hIce < hThinIce (as the comments say)
429      and in thsice_extend.F:
430      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
431      - start to form ice as soon as the minimum ice-volume is reachable.
432     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
433      and cpl_aim+ocn
434    o pkg/kpp
435     - move computation of surface related input fields to KPP into a new
436       subroutine kpp_forcing_surf.F
437     - remove wrong (within bi,bj loops) EXCH calls.
438     - little cleaning (add argument myThid in last position, cvs header ...)
439     - for now, fix conservation problem by exchanging KPPviscAz (may not
440       be the best fix)
441    o pkg/seaice
442     - check for inconsistent evp parameter/cpp-flag combination
443     - remove leftover errIO flat for obsolete name list error handling
444    o OpenAD
445     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
446    
447    checkpoint59a
448    o pkg/seaice: some parameter clarifications and a little bit of clean up
449    o pkg/thsice: rename run-time parameters:
450       himin       -> hIceMin
451       himin0      -> hThinIce
452       hihig       -> hThickIce
453       i0          -> i0swFrac
454       transCoef   -> bMeltCoef
455       frac_energy -> fracMelting
456      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
457       with default values (for now) that do not change the results.
458      remove old version of thsice vars advection in pkg/seaice.
459    o in FFIELDS.h:
460      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
461      - make pLoad & sIceLoad always available (but still only used if
462         ATMOSPHERIC_LOADING is #define).
463    o pkg/kpp: replaced _KPP_RL with _RL
464    o bug fixes for vertical diffusivity computations when both KPP and
465        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
466        are no longer updating the vertical diffusivity array
467        (passed as argument) but are (re-) setting those arrays.
468    o pkg/seaice: fix bug in evp solver, while doing that
469      - change (improve?) discretization of stress computations for both
470        cgrid-lsr and evp solver
471      - add a new routine to compute strain rates
472      - the above changes lab_sea results
473      - add no slip conditions for evp solver (off by default), lsr-version
474        may follow
475      - fix exchange for shear at Z-points (does not change lab_sea)
476      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
477        (to force the user to pick a time step since there is not "safe" way
478        of choosing it)
479      - add principal stress diagnostics
480      - rearrange fields for evp a little to avoid having to call a: too many
481        exchanges and b: exchanges for stress trensor components which we do
482        not have.
483      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
484        of evp, complete rewrite for lsr case (latter is does not yet work
485        in all cases)
486    o pkg/kpp: add code to have mixing in shelf ice caverns
487      - add myThid to all kpp routines (long overdue)
488    
489    checkpoint59
490    o pkg/exf:
491      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
492        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
493      - move exf header files from lower_case.h to UPPER_CASE.h ;
494        add missing cvs Header & Name
495      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
496      - add namelist param. selectStressGridPosition, exf_monFreq
497      - retire many _CLIM routines, and remove data.exf_clim
498        + params moved to data.exf
499        + climsst, climsss now handled by exf_set_gen, i.e.
500          climss?period=0 refers to constant field,
501          climss?period=-12 to monthly forcing
502      - split up namelists in data.exf
503    o pkg/seaice:
504      - remove seaice_exch and seaice_exch_uv
505      - remove superfluous exchange of theta
506      - add myThid to seaice_budget_ocean/ice
507      - add new interface for atmospheric wind forcing (C-grid only)
508        + new routine
509        + two new field (taux, tauy for stress over ice)
510        + removed one global field (DAIRN) for C-grid case only
511    o pkg/thsise
512      - 2nd set of modifs for thsice adjoint in conjunction with exf
513    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
514    
515    checkpoint58y_post
516    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
517      vertical diffusivity, similar to that in MOM4; turned on using
518      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
519      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
520    o Added capability for 3D specification of background vertical diffusion
521      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
522      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
523      "data" file that contains the 3D vertical diffusivity coefficients.
524    o ice dynamics (pkg/seaice) with thsice thermodynamics:
525      - add code within pkg thsice to advect & diffuse sea-ice fields
526      similar to (and will replace) what has been added in  seaice_advdiff.F,
527      but: - conserving Mass, Heat & Salt.
528           - better when using non-linear advection scheme (not yet fully tested)
529           - can also be used in atmospheric set-up (for now, only the diffusion).
530    
531    checkpoint58x_post
532    o IO option for global-file compact format:
533      - add options when generating topology (utils/exch2/matlab-topology-generator)
534      - add I/O capability (pkg/mdsio).
535      - adapt utils/matlab/rdmds.m to read this format.
536      for now long-line format not yet supported by pkg/mdsio (& exch2).
537    o shelfice: add a few diagnostics
538    
539    checkpoint58w_post
540    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
541      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
542      (and replace horiVertRatio in NH code).
543      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
544                         and tutorial_plume_on_slope (sensitive to truncation)
545    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
546      directly to drive seaice model (C-grid only)
547    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
548     - reintroduce computation of wind from stress,
549     - compute tau (in exf_bulkformulae.F) from windstress averaged to
550       mass points to avoid tau = 0
551     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
552    o rdmnc.m: make it work with "global" files created with gluemnc
553    o rdmnc.m : some improvements in dealing with singleton dimension
554      (tested on all testreport mnc output files).
555    o genmake2: disable pkg/profiles if netcdf test fails.
556    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
557    o move call to cal_readparms up to make calendar parameters/variable available
558      to all packages
559    
560    checkpoint58v_post
561    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
562      useDynP_inEos_Zc tested.
563    o pkg/exf: changes to properly interpolate/mask/scale initial fields
564    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
565      and portions thereof.  See read_cs.txt for description and examples.
566    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
567      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
568      following the great-circle arc between those 2 points.
569    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
570      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
571    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
572     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
573     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
574     - still needs work (not working with some options ; efficiency to improve)
575       and serious testing.
576     - use this scheme for temperature & salinity in 2 advection test exp.:
577       advect_xy & advect_xz, respectively.
578    
579    checkpoint58u_post
580    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
581    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
582    o testreport: add option "-skipdir" to skip some test.
583    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
584      momentum calculation.
585    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
586    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
587      remove checkpoint.F and the_correction_step.F (no longer used);
588      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
589    o add option (linFSConserveTr) to correct for tracer source/sink due to
590      Linear Free surface
591    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
592    o pkg/thsice: fix reading mnc-pickups
593    
594    checkpoint58t_post
595    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
596    o pkg/mdsio:
597     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
598       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
599       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
600     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
601     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
602       either MDS_READ_FIELD or MDS_WRITE_FIELD )
603     - new S/R (to replace MDSWRITEMETA), which allows to write more
604       informations (variable names, time ...) to meta files.
605     - modify rdmds.m to give back the meta file content.
606    o pkg/diagnostics: change vertical interpolation to be safer, and more
607       flexible (define p-levels to interpolate to in data.diagnostics);
608      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
609       diagnostic pointer.
610    o pkg/seaice: more cleaning up of seaice_growth, added many comments
611    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
612    o fix multi-category seaice:
613     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
614       SEAICE_MULTICATEGORY
615     - fix short wave heat flux
616    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
617       and allow to use EVP solver. Change forward lab_sea: test both EVP
618       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
619    o Initial check-in of lab_sea adjoint
620      (very similar to natl_box_adjoint/code_seaice)
621      * used C-grid and EVP solver
622      * used KPP, GM/Redi
623      * uses inAdExact=.TRUE.
624      * gradient checks fail for both ADM and TLM
625        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
626        f.d. gradients actually seem more problematic than ADM, TLM gradients;
627        issue is related to forward mismatch between g77 an ifort
628    o pkg/seaice: overhaul of thermodynamics
629     - growth.F and groatb.F are replaced by new routine seaice_growth.F
630     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
631     - move a few global fields out of SEAICE.h into seaice_growth.F and
632       make them 2D (FICE/QNETO/ ...)
633     - remove FO (it is the same as QNETO)
634     - introduce a few local fields to avoid modifying external fields such
635       as atemp, etc.
636    
637    checkpoint58s_post
638    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
639      changed exf_set_gen.F so that
640        genperiod=0 means input file is one time-constant field and
641        genperiod=-12 means input file contains 12 monthly means
642    o CG2D: use pre-computed solver main-diagonal (stored in common block);
643      this affects truncation error ; generate new output file for exp. which
644      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
645        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
646        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
647        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
648        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
649        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
650    o start implementation of deep-atmosphere and anelastic formulation
651    o verification: remove 2nd copy of input files and use script "prepare_run"
652      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
653    o mom_common/vecinv/fluxform: fix a few initialisation isssues
654    o profiles: fix for multithreaded case
655    
656    o diagnostics: rename few diags:
657      s/'PRESSURE'/'RCENTER '/g
658      s/'TICE    '/'oceFreez'/g
659      s/'TAUX    '/'oceTAUX '/g
660      s/'TAUY    '/'oceTAUY '/g
661      s/'SWFLUX  '/'oceQsw  '/g
662      s/DIFx/DFxE/g
663      s/DIFy/DFyE/g
664      and add few ocean-forcing diagnostics:
665      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
666    o modifications to pkg/seaice/growth.F and budget.F, which change results of
667      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
668      as actual snow thickness.  It now refers everywhere to effective snow
669      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
670    
671    checkpoint58r_post
672    o modifications to pkg/seaice/growth.F, which change results of
673      lab_sea experiment: fixes pertain to melting snow over open water, to
674      masking EVAP under sea ice, and to using the correct AREA variable for
675      computations of EVAP, PRECIP, HSNOW, and GHEFF
676    o add ability to read bathy, salt, and theta using MNC (off by def)
677    o add flooding algorithm and advection of HSNOW for pkg/seaice;
678      both are turned off by default and do no change any results
679    o seaice advection with pkg/thsice: a step toward the use of non-linear
680      advection scheme, but #ifdef or commented out for now (requires more EXCH).
681    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
682      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
683      in natl_box (affects results @ truncation level: update output.txt)
684    o multi-threading and IO:
685      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
686      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
687        (needed to work with SingleCpuIO): tested in all verif. exp.
688    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
689      affects the results (but none of the verification test uses this scheme).
690    o Adding some pkg/diagnostics capability to pkg/seaice
691      (will certainly be subject to changes)
692    o ctrl: adding new control variables:
693      lwflux, lwdown, evap, snowprecip, apressure, runoff
694    
695    checkpoint58q_post
696    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
697      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
698      high_res_cube configuration by 4% on Columbia.
699    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
700      add (in global_with_exf/code) a version of EXF_INTERP_READ without
701      dynamical allocation (seems to work in multi-threaded).
702    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
703      single CPU io) so that TAF does not have to see EESUPPORT.h
704    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
705    
706    checkpoint58p_post
707    o obcs: stop if obcs is used with useCDscheme = .true.
708    o shelfice:
709     - fix a sign error so that no slip at shelfice interface works
710     - remove stop for combination non-hydrostatic code and shelfice. That does
711       not mean, that the results are correct, but at least they are numerically
712       stable
713    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
714    o added adjoint exch routined for all exch*3d* routines
715      and updated flow directives
716    
717    checkpoint58o_post
718    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
719      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
720    o change controling S/R for writing pickup file (new S/R do_write_pickup)
721      and clean-up reading/writing of pickup files.
722    o fix local version of read/write pickup (NH part) in rotating_tank/code
723    o simplify EXCH interface:
724     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
725     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
726    o added the regrid package
727    o shelfice:
728     - add a simple boundary layer scheme to reduce noise
729     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
730    
731    checkpoint58n_post
732    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
733       local variable (not in common block).
734    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
735      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
736      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
737        to work with SingleCpuIO.
738    o add "_d 0" to real constant of pkg/cfc subroutines ;
739       update exp. cfc_exemple & tutorial_cfc_offline output files.
740    o multi-threading and IO:
741      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
742        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
743      - barrier before and after reading.
744      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
745      - avoid using MDS_WRITELOCAL for LAND pkg output.
746      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
747        common-block variables ; Allows multi-threading with master-thread IO.
748    o change default MAX_NO_THREADS from 32 to 4 ;
749      and stop cleanly when MAX_NO_THREADS is too small.
750    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
751    
752    checkpoint58m_post
753    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
754       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
755    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
756       keep global_ocean.90x40x15 (for AD testing) with former secondary test
757       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
758    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
759        add MITgcm_tutorials (= code + all the tutorials)
760    o ecco, option to compute cost for total ssh (mean+anom)
761    o consistent with addition of ptracer and ssh in pkg/profiles
762    o profiles: adding ptracer and ssh
763    o testreport: change multi-test output-file name
764      (from output.txt.{name} to output.{name}.txt)
765    o profiles: now ok for mutli-tiles case
766    o seaice: add 4 parameters for different advection schemes for area,
767      (effective) seaice thickness, enthalphy, and snow height. Their default
768      is the standard parameter SEAICEadvScheme
769    o calc_gw:
770     - add cosFacU in zonal viscous flux (harmonic.visc.).
771     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
772       of tutorial_plume_on_slope.
773    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
774    o calc_gw: true flux-form, account for horizontal grid spacing.
775      update rotating_tank results, but not plume_on_slope (affected at
776      truncation level, 11 digits).
777    
778    checkpoint58l_post
779    o calc_gw:
780     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
781     - remove side-drag for now (need to fix it); update plume_on_slope results.
782     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
783    o commit code to make SST/SSS weights spatially variable
784      (based on either variable in-situ or variable initial T/S weights)
785    o pkg/ecco:
786      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
787        now based on horizontally varying weights wthetaLev, wsaltLev
788      * cost_averagesflags now returns year indices in addition to day, month
789      * sflux balance is performed on annual basis
790        (sflxumm, sfluxmm2, bal_sfluxmm)
791      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
792        including separate counting and multipliers
793    o pkg/rbcs
794      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
795    
796    checkpoint58k_post
797    o testreport:
798     - always build in dir. "build" (if not there, mkdir build instead of building
799       & running in input)
800     - run in dir run (if it exists), in build otherwise.
801     - call prepare_run (if input/prepare_run exists)
802     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
803    o pkg/exf modifications to interpolation and rotation routines for more
804       reasonable treatment of North Pole singularity: for tracers North Pole
805       value is set to northernmost zonal-mean value, for zonal velocity it is
806       set to zero, and for meridional velocity it is set to northernmost value.
807    o pkg/exf/exf_check_range.F
808     - add tile index to diagnostics and move stop statement to the very
809       end of the routine.
810    o pkg/diagnostics: (diagnostics_main_init.F)
811      define title of isomorphic variables according to the current config.
812    o pkg/thsice with pkg/seaice dynamics:
813    - fix domain of computation (interior only, required for exf) and do exchanges
814    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
815    o towards a standard way of dealing with multi-threading in MONITOR
816      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
817    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
818       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
819    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
820    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
821    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
822       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
823    o tracer advection:
824     - clean-up and simplify calc_common_factors.F
825     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
826       advection subroutine (but still not used within DST advection S/R)
827    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
828    
829    checkpoint58j_post
830    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
831      from file (collects calls previously in FORWARD_STEP)
832    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
833    o adjoint store dir. adjusted accordingly
834    o genmake2
835      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
836    
837    checkpoint58i_post
838    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
839      on wind stress (SEAICEstressFactor defaults to 1.)
840    o Total number of Timers is finite (<=40): comment out 2 non-essential one
841      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
842    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
843      on CS-grid: no longer loosing mass.
844    o exf & curvilinear-grid: no longer modify longitude xC & xG.
845    o pkg/ggl90: fix sloppy output and fix a bug
846    o pkg/seaice: added SEAICEuseEVPpickup parameter
847      - Set to false in order to start EVP solver with
848        non-EVP pickup files when using SEAICEuseEVP
849      - fix sign error in diffusion in seaice_calc_rhs
850    
851    checkpoint58h_post
852    * Modifications for bottom topography control
853      o replace hFacC by _hFacC at various places
854      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
855      o add non-self-adjoint cg2d_nsa
856      o update autodiff support routines
857      o re-initialise hfac after ctrl_depth_ini
858      o works for 5x5 box, doesnt work for global_ocean.90x40x15
859    * Adding verification for 5x5 box (4-layer) bottom topography control
860    
861    checkpoint58g_post
862    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
863       used for mean seasonal cycle, mean diurnal cycle); add an example
864       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
865    o pkg/ggl90:
866      - add parameter (minimum surface kinetic energy)
867      - fix bug (avoiding division by zero)
868    o couple pkg/thsice to pkg/seaice:
869      - modify advection in seaice to accomodate new scalar fields to be advected
870      - only muliDimAdection scheme work with seaice/thsice
871      - mapping of thsice-variables to seaice-variables, back and forth
872      - does not break the verification experiments, but does not give the
873        desired results either
874    o pkg/seaice
875      - make (default) second order advection a bit less confusing?
876    
877    checkpoint58f_post
878    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
879      to pkg/seaice):
880      - new routines thsice_map_exf and thsice_get_exf provide the interface
881      - add an additional formal parameter to thsice_solve4temp
882    o pkg/exf:
883      - add new fields wspeed, snowprecip (to be able to couple to thsice)
884      - correct Stefan-Boltzmann constant
885      - new parameter for longwave surface emittance
886      - separate some stuff from exf_bulkformulae into new routines  
887        exf_radiation, exf_wind
888      - add new parameters and constants: longwave emissivity for ocean, ice
889        and snow, evaporation parameters over ice
890      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
891        either wind from stress or stress from wind
892    o pkg/thSIce:
893    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
894    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
895       and THSICE_CALC_THICKN
896    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
897    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
898      to make debugging easier.
899    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
900    o pkg/bulk_force:
901      - clean-up comments and parameters ;
902      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
903    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
904      generate new output for test-experiment: aim.5l_cs.thSI
905    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
906      testreport accordingly
907    
908    checkpoint58e_post
909    o SEAICE_CGRID adjoint done
910    o R_STAR adjoint implemented.
911      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
912      * need to sort out init. of h0facc, etc.
913    o Make pkg/profile fully independent of ecco,cost, etc. stuff
914      to be able to use it in pure forward.
915    
916    checkpoint58d_post
917    o upgrade simple test-experiment to tutorial example:
918     step.1: duplicate the experiment and (step.2) will remove the old copy.
919      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
920      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
921      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
922      tutorial_global_oce_biogeo    <- copy of dic_example
923      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
924      tutorial_plume_on_slope       <- copy of plume_on_slope
925      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
926      tutorial_global_oce_optim     <- empty for now (David ?)
927      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
928     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
929    o correct a sign problem in cost_scat.F
930    o obcs and ptracers: fix boundary conditions for advections schemes
931      with larger stencil
932    o thsice adjoint: start
933    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
934      completeness
935    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
936      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
937    o ptracers adjoint:
938      * avoid extensive recomputatations
939      * fix missing re-init. of gptr (missed by TAF)
940    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
941      me to turn off the excessive output to STDOUT that this package produces
942    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
943      and add those terms in Vector-Invariant formulation.
944    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
945      if the control period (xx_hfluxperiod etc) is 0
946    o in profiles pkg, clean routines and fix details
947    o in ecco pkg, reading ssh data:
948      fix problem in case the model does not start at iter0=0
949    o fix mnc-pickup/restart for ptracers
950    o new package prifiles:
951      code to compute profile-based cost by Gael Forget
952      (modifs in ecco, ctrl, autodiff)
953    o Benign bug fix in initialization (spotted by M. Mazloff) of
954      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
955    
956    checkpoint58c_post
957    o adjoint: finish NLFS adjoint and provide reference output in
958      verification/global_ocean.90x40x15/results_ad_nlfs
959    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
960      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
961      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
962      with SEAICE_CGRID defined.
963    o move calendarDumps from "data" to "data.cal" and clean-up the code
964      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
965    o add useEXF & useCAL flags (for now, set in hard-coded way)
966    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
967      (were missing in NH mode, and wrong in quasihydrostatic mode).
968      waiting for Chris updated version of calc_gw to add those CALLs.
969    o fix bug in quasihydrostatic S/R ;
970      add a test for this option: global_ocean.90x40x15.qshyd
971    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
972      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
973    o add on/off flag useOffLine for package OFFLINE
974    o seaice:
975      - modify advection so that it works also on the C-grid
976      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
977        problem in multi-tile runs with C-grid
978      - add flags for clipping ice velocities and/or masking solver forcing
979      - fix drag (ocean on ice) formulation and a bug that caused noise in the
980        C-grid solver
981      - added a few comments to seaice_diffusion.F
982      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
983        are now exclusive)
984      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
985        required re-ordering the code a little:
986       + make DAIRN global variable (defined in SEAICE)
987       + move computation of the viscosities eta and zeta into a new separate
988         routine (because I need to recompute them in seaice_ocean_stress.F)
989    
990    checkpoint58b_post
991    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
992      update output.txt of exp. aim.5l_cs.thSI
993    o various mnc cleanups and improvements:
994      + shrink lookup tables by factor of ~4
995      + better error reporting when running out of lookup space
996      + able to handle longer path/file names (up to 500 chars)
997    o adjoint:
998      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
999      - TBD: "hidden" mom_vecinv recomp. in dynamics
1000    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1001     (allow to differentiate between forcing components using new integer flags:
1002      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1003     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1004    o ecco
1005      - enable trend removal from SSH anomaly obs.
1006    o adjoint
1007      - a fix for PmEpR when #undef EXACT_CONSERV
1008      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1009      - try to fix "hidden" recomp. in forward_step for NLFS
1010        (NLFS seems broken sometimes after I checked it in)
1011    o seaice:
1012     - add c-grid version of the dynamic solver:
1013       + three new routines that are the c-grid substitute lsr, dynsolver
1014         and ostres
1015       + put a few fields that were local to dynsolver into global common
1016         blocks, so that I can move the computation of stresses etc into
1017         seaice_lsr (saves coding but may break the adjoint).
1018     - replace more hardwired parameters by runtime parameters
1019     - add ice masks that mask the rhs of the implicit solvers where there
1020       is no ice (commented out in seaice_dynsolver, because i am not sure
1021       if this works properly), eventually this should replace the clipping
1022       of ice velocities in seaice_dynsolver to +/-40cm/s.
1023    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1024      include it only where its needed
1025    o move balancing of fluxes before the call of external_forcing_surf
1026    o seaice:
1027      - correct units of turning angles (now they are really in degrees)
1028      - move computation of GWATX/Y out of main routine into dynsolver
1029      - initialize GWATX/Y in seaice_init
1030    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1031      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1032    o seaice: add runtime flags for turning angles (default to zero)
1033    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1034      and trend from exf forcing and ctrl control adjustments
1035    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1036      (since checkpoint57x_post)
1037    o change the default rotation period to 86164.s = the Earth rotation
1038    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1039      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1040    o seaice advection: add code for choosing between the default (2nd order
1041      central differences) and multiDim advection schemes provided by
1042      pkg/generic_advdiff
1043    o seaice:
1044      - removed all references to SEAICE_GRID.h fields from
1045        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1046        (cubed-sphere configuration will change a little)
1047      - grid computations in seaice_init are obsolete now.
1048      - cleaned up code a little so that is easier to read (hopefully).
1049      - added new (better?) discretizations of default advection and diffusion
1050        (turn on with SEAICEuseFluxForm)
1051      - replace 1 in 3d global fields by kSurface in growth.F
1052      
1053    checkpoint58a_post
1054    o seaice:
1055      - bug fix in advect.F
1056    o shelfice:
1057      - separate shelfice load anomaly from pload (breaks with time
1058        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1059        Its default is 0., but it may be computed more cleverly from (unknown)
1060        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1061        done offline. A good approximation of the pressure load anomaly is
1062        necessary to avoid large initial adjustment processes underneath
1063        deep-reaching shelfice.
1064      - small fix in ISOMIP shelfice_thermodynamics
1065      - add more sophisticated thermodynamics of Hellmer (1989), this is
1066        now the default
1067      - give a few constants more intuitive names
1068    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1069      if bulk formulae are used in long integration (especially EmPmR). Turn
1070      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1071      if balancePrintMean, the imbalance that is substracted is printed to
1072      STDOUT.
1073    o fix bug (typo) in obcs_apply_eta.F
1074    o add a new package shelfice which enables us to model the circulation
1075      underneath shelf-ice with draughts of hundreds of meters.
1076     - works
1077     - to do: + include improved thermodynamics
1078              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1079                instead of new field kTopC
1080              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1081                instead of new field R_shelfIce and new code in ini_depth.F
1082                and ini_mask_etc.F?
1083              + adjust vertical mixing schemes?
1084    o seaice pkg:
1085     - add a cpp-flag to include a simple formula for a salinity dependent
1086       freezing point of sea water at the surface
1087     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1088       meridional stresses are now different (and hopefully correct)
1089    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1090       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1091       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1092    o pkg/diagnostics: add options and parameters for regional-statistics
1093       diagnostics ; define regions by reading a region-mask from a file
1094       (might add other options later)
1095    o pkg/bulk_force:
1096     - add option and parameters to use AIM surface-flux formulae.
1097     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1098       others forcing fields (defined in PARM05, parameter file "data") are loaded
1099       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1100     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1101     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1102     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1103       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1104     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1105    
1106    checkpoint58
1107    o add "--embed-source" option to genmake2 which, when the supporting
1108      tools can be compiled (as determined by genmake2) will turn on the
1109      embed_files package which then embeds the entire MITgcm source code
1110      (*.[fFhc] + Makefile) used for the build within the executable
1111      - requested by CNH but off by default
1112      - adds a paltry <9MB to the mitgcmuv executable in most cases
1113      - only writes the output when useEMBEDSRC in eedata is true
1114    o clean up 3-dim. relaxation codes:
1115      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1116      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1117      * Thanks to Tom Haine for testing!
1118    
1119    checkpoint57z_post
1120    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1121      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1122    o fix the pickup behavior for obcs in combination with ptracers
1123    o fix a bug in ptracers_external_fields_load
1124    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1125      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1126    o transfered surface NH pressure to eta field (if exactConserv).
1127    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1128         and update lab_sea output.txt file.
1129    o completing 3-dim. relaxation code: additional term
1130         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1131      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1132      * At compile time, in "EXF_OPTIONS.h" set
1133          #define  ALLOW_CLIMTEMP_RELAXATION
1134          #define  ALLOW_CLIMSALT_RELAXATION
1135      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1136          tauThetaClimRelax3Dim = 15552000.0,
1137          tauSaltClimRelax3Dim  = 15552000.0,
1138      * 3 cases:
1139          1) Use a constant-in-time 3-dim. field
1140          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1141          3) Real-time relax. to time-evolving prescribed field
1142    o Adding Laplacian-type smoothness constraint on
1143      initial and boundary (forcing) controls (ic, bc)
1144      * enable at compile-time via
1145        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1146      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1147      * Absolute scale somewhat unclear so far
1148      * no area weighting was included since no other cost term does so far
1149    
1150    checkpoint57y_post
1151    First step for a NLFS adjoint
1152    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1153    o new init. routines for calc_r_star, calc_surf_dr
1154    o still need to deal with ini_masks_etc
1155    o testreport seemed happy
1156    checkpoint57y_pre
1157    
1158    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1159    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1160    o add new offset feature to offline pkg (plus minor cleanup)
1161    o cfc fixes for final year of integration
1162    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1163      be in GCHEM_OPTIONS).
1164    
1165    checkpoint57x_post
1166    o fix testreport Pb in multiple test experiment.
1167    o cleanup our namelist syntax in verification:
1168      - make it more F95 standards compliant (some work still needed)
1169      - allows the vast majority of our tests to work with gfortran
1170    o Non-Hydrostatic:
1171     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1172     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1173    o Allow to apply AB on T,S rather than on AB(gT,gS):
1174     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1175     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1176       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1177     - need a "clever" read_pickup to restart from the other AB formulation
1178    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1179    o remove some unused variables (reduces number of compiler warnings)
1180    o adjoint
1181      * Disable useVariableViscosity for adjoint for time being
1182        (there are a number of extensive recomputations)
1183      * Initialize certain variables needed for adjoint
1184    
1185    checkpoint57w_post
1186    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1187                 fix the singleCpuIO RS version of MDSWRITEFIELD
1188       and add a WARNING if using globalFiles=T with multi-processors.
1189    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1190      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1191    o tracer advection scheme:
1192      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1193       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1194       was not very convenient).
1195      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1196       (further tests needed for the implicit DST & Flux-Limiter schemes).
1197    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1198      and sRef for convenience, handy, when you want to initialize
1199      ptracers in a large domain with a constant non-zero value. Also,
1200      untangle ptracers_init.F a little.
1201    
1202    checkpoint57v_post
1203    o change dome exp. to use variable viscosity in side-drag terms.
1204    o remove all the files from the cfc_offline test since they are now
1205      incorporated into tutorial_cfc_offline which has been producing
1206      identical results for a few days of testing
1207    o add new parameter: sideDragFactor to enable half-slip-side BC
1208      and change side-drag S/R to use viscosity from mom_calc_visc
1209      (can switch back by setting sideDragFactor=0.); affects results at
1210      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1211       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1212    o vorticity & strain are now computed without masking, to account for
1213      no-slip-side BC in variable viscosity calculation ; mask is applied
1214      anyway later on, before computing advection/coriolis terms.
1215    o modify exp4 to test new obcs support for reading from external files
1216      and for passive tracers
1217    o fix behavior of ptracers_monitor when monitor output is written to a
1218      netcdf-file; still not independent of monitor.F (writes in the same
1219      file).
1220    o change default value of tRef (put a uniform, meaningful value for ocean
1221      & atmos) and initialize sRef (was missing, as Martin mentioned).
1222    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1223      to be proportional to enstrophy dissipation length.  Thus,
1224       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1225      This is now consistent with Smagorinsky and with the manual.
1226    
1227    checkpoint57u_post
1228    o OBCS and PTRACERS: add open boundary support for passive tracers
1229      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1230        OB-values from file; this is not different from the way theta and salinity
1231        are treated
1232      - however, Orlanski-radiation conditions are not supported, and the model
1233        will stop if you use pTracers and Orlanski at the same time.
1234      - beefed up the rountine obcs_external_fields_load: now only those open
1235        boundary values are overwritten with values from files for which there
1236        are really files, otherwise the OB-fields remain untouched. This makes
1237        it possible to use different OBs at different ends of the domain (as
1238        with EXF)
1239    o reduce number of exch calls in shap_filt (s2).
1240    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1241      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1242    
1243    checkpoint57t_post
1244    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1245    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1246      same truncation, independent of the face number: affects affects several
1247      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1248    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1249      note that biharmonic viscosity + no-slip was not tested in any experiment.
1250    o fix bug in non-linear free-surf side-drag ; generate new output for
1251      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1252    o make mnc honor the writeBinaryPrec flag for most kinds of output
1253    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1254    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1255      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1256    o add brackets in multi-terms sum to get same truncation, independent of
1257      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1258      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1259    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1260      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1261      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1262      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1263      Suggested values of viscosity parameters found in mom_calc_visc.
1264      Many new viscosity diagnostics available.
1265    
1266    checkpoint57s_post
1267    o Add clearing-house for viscosity calculations, mom_calc_visc and
1268      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1269      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1270      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1271      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1272      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1273      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1274      ViscAhStrain and viscAhTension are now retired.
1275    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1276    o In response to JMC's bug report, genmake2 now ignores any soft-links
1277      that it finds in the *current* directory when searching for files.
1278      Soft-links found in any other source directories will still work as
1279      they did before.
1280    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1281      a C routine to unlimit the stack size
1282    o mnc-ify pkg/aim snapshot vars
1283    o mnc-ify pkg/land as requested by Daniel
1284    o various changes to mnc including:
1285      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1286      - output can now be grouped so that all files within a group
1287          change the ITER portion of their names in lock-step together
1288      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1289          and works with both EXCH1 and EXCH2 (but needs more testing)
1290      - writing works for all verification test cases w/ g77 on Linux
1291    
1292    checkpoint57r_post
1293    o make MNC variable initialization happen earlier
1294    o add diagnostics for (almost) each term of the momentum Eq.
1295    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1296    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1297    o remove MINIMAL_TAVE_OUTPUT option ;
1298      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1299    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1300      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1301    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1302    o add time-dependent SST, SSS control
1303    o cost terms in ecco/ modularized (new cost_generic.F)
1304    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1305    o new infrastructure for seaice model vs. obs misfits in seaice/
1306      * driver from the_main_loop.F is seaice_cost_driver.F
1307      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1308      * gradient check in Exp. 6a of natl_box_adjoint/
1309    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1310      (see README file)
1311    
1312    checkpoint57q_post
1313    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1314    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1315      - bug was reported by Jean-Michel and Ian Fenty
1316    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1317      update exp. cpl_aim+ocn output.
1318    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1319      Needed for high-res. runs with large global files
1320      to be able to limit tapelev size
1321    o Changed some tests for adjoint:
1322      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1323      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1324      * global_ocean.90x40x15/ back to default 3-level checkpointing
1325    o Modifications to enable scripted COMMON to MODULE conversion
1326      * verification/OpenAD/code/ has necessary scripts and description;
1327      * converts, compiles and runs successfully;
1328    
1329    checkpoint57p_post
1330    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1331    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1332      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1333    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1334    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1335      (was already the case for dissipation with mom_vecinv,
1336       and also the case for grad.PhiHyd when staggered-timeStep)
1337      This will allow to put dissipation out-off the AB time-stepping.
1338     Unfortunately, affects truncation error. Update output of exp. that "fails"
1339      (cg2d matching number) and leave the others for later: front_relax(10),
1340      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1341      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1342    
1343    checkpoint57o_post
1344    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1345      (2) its ready to be documented during the 20050801 DocFest
1346    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1347      for ideal_2D_oce and lab_sea on linux_ia32_g77
1348    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1349      in global1x1_tot/code_seaice_adj to access indices 32, 33
1350      (worth another tag)
1351    
1352    checkpoint57n_post
1353    o adding precip control xx_precip 32
1354    o adding swflux control xx_swflux 33
1355    o Replacing 10 forcing penalty cost routines by 1 generic.
1356    o Implementing partitioning in time-mean and variable adjustment
1357      for atmos. state.
1358    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1359    o in natl_box_adjoint:
1360      * updated exp 1 to 10
1361        (but does not have time-mean vs. variable split results yet)
1362    o updated global1x1/*_seaice_adj/
1363      to incorporate latest changes
1364    o enable useSingleCpuIO for mdsio vector routines
1365      (applies in particular to tapelev I/O)
1366    o removed inefficient K-loop in all active_file*control*.F
1367    
1368    checkpoint57m_post
1369    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
1370      and advect_cs (use EXCH-2 and standard cs-32 grid files).
1371    o pkg/exch2: filling of face-corner halo regions is optional
1372      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
1373    
1374    checkpoint57l_post
1375     tag before updating tutorials (pre-release-2)
1376    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
1377       for output and interpolation of input fields onto model grid)
1378    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
1379       Affects results of exp. rotating_tank ; update output.txt.
1380    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
1381          and taking the square quantity and/or using a fraction-weight field.
1382    o fix aim_diagnostics_init.F mate numbers.
1383    o add mnc output capability to diagnostics/diagstat and update
1384      our cvsignore files for the ACSII output generated
1385    
1386    checkpoint57k_post
1387    o lab_sea now uses diagnostics package and provides a suite of
1388      new EXF diagnostics output.
1389    
1390    checkpoint57j_post
1391    o exf
1392      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1393        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1394        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1395      * extended diagnostics output
1396        - now includes all EXF variables
1397        - hs, hl moved to common block
1398        - separate S/R for diagnostics, called after ctrl vector is added
1399        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1400        - EXFqnet contains true Qnet (i.e. includes qsw)
1401      * updated verif. lab_sea, global_with_exf
1402      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1403        to ensure that diagnostics sees a true EXFqnet
1404    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1405    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1406      several times with different frequencies.
1407    o mnc-ify the thsice package as requested by Daniel Enderton
1408      - the monitor--MNC output needs work
1409      - many attributes need to be added (most are currently blank)
1410    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1411      - many attributes need to be added (most are currently blank)
1412    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
1413    o add Sadourny like discretization to the 4th.O vorticity advection scheme
1414    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
1415      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
1416         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
1417    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
1418     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
1419    
1420    checkpoint57i_post
1421    o Diagnostics package was changed: diagnostic allocation is now deactivated
1422      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1423    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1424      add 1rst Order upwind vertical Shear.
1425    o add a quick fix for A/B checkpointing in OFFLINE mode
1426    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1427      end-run around the C/Fortran linking horror in eesup/src/timers.F
1428    o added pkg/runclock: allows user to terminate run based on wall clock
1429    o added non-hydrostatic scaling parameter: nh_am2
1430    o pkg/my82: futile attempt to make results compiler-independent by adding
1431      some "_d 0", etc. no effect.
1432    o for mnc output, fill the 'T' coordinate var with myTime and create a
1433      separate 'iter' variable for iteration count
1434    o pkg/diagnostics:
1435      add new capability: output of Global/Regional & per-level statistics ;
1436      tested against monitor output (including land & thSIce) on various exp.
1437    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1438    
1439    checkpoint57h_done
1440      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1441      data.diagnostics, data.gchem, data.ptracers) is done.
1442    
1443    o pkg/diagnostics: prepare for Global/Regional statistics.
1444      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1445    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1446      and rename it: DIFFERENT_MULTIPLE
1447    
1448    checkpoint57h_post
1449    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1450    o pkg/diagnostics: change output frequency, now in seconds (instead
1451      of Nb of iterations). This requires to change data.diagnostics.
1452    checkpoint57h_pre
1453    
1454    o in mnc, let the user create the output dir if both mnc_outdir_date
1455      and mnc_outdir_num are false
1456    o add fflags() to pkg/diagnostics which allows one to specify, on a
1457      per-file basis, the file precision [default behavior is unchanged]
1458    o added diagnostics to pkg/kpp, including computation of mixed layer
1459      depth based on a temperature/density criterion
1460    o updated verification/natl_box to test the new pkg/kpp diagnostics
1461    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1462    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1463    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1464      not mnc -- this mistake was found by JMC and is now corrected
1465    
1466    checkpoint57g_post
1467    o add Adams-Bashforth 3rd Order time stepping:
1468      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1469      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1470    checkpoint57g_pre
1471    
1472    o make lambda[Theta,Salt]ClimRelax spatially varying
1473      (default remains spatially uniform constant based on tau)
1474    o added new control variables
1475      * init. uVel, vVel, etanN
1476      * lambda[Theta,Salt]ClimRelax
1477    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1478      (suggested by G. Forget)
1479    
1480    checkpoint57f_post
1481    o add parameter "baseTime" = model base time = time at iteration zero
1482      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1483      account for baseTime shift
1484    o move Coriolis arrays from PARAMS.h to GRID.h
1485    checkpoint57f_pre
1486    
1487    o mnc-ifying the seaice package
1488    o introduced an alternative length scale calculation for use in the limiting
1489      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1490    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1491    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1492      as well as grad(vort3).  Made it compatible with both approximate form
1493      for the cubed sphere and full form of these gradients.  Added flag
1494      useFullLeith to select between approximate and full form.  
1495    o add "d0" in getcon.F to reduce differences between compilers/platforms
1496      update output.txt of exp. fizhi-gridalt-hs
1497    o change port_rand funtion to allow to set the seed.
1498    o fix obscure MNC bug involving conversion between reals and integers
1499      - it caused no problems with certain (eg. gcc, ifc) compilers but the
1500        new version is now more standards-compliant
1501    o adjoint-related modifications
1502      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
1503      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
1504      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
1505    
1506    checkpoint57e_post
1507    o Adding eddy stress controls a la Ferreira et al.
1508    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
1509    
1510    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
1511      update output.txt of exp. fizhi-gridalt-hs
1512    o add more "Z" dimensions and associated coordinate vars to MNC
1513    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
1514    o parameter calendarDumps: when set, approximate months (30-31 days) and years
1515      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
1516      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
1517      months and years.  Requires pkg/cal.
1518    o diagnostics: add pickup functionality
1519      - off by default for backwards compatibility
1520      - current version only uses MDSIO -- MNC will be added
1521    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
1522    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
1523    
1524    checkpoint57d_post
1525    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1526    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1527      output from the diagnostics package
1528    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1529    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1530      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1531    o add coordinate variables to the MNC output from the diagnostics package
1532    o change MNC-flags default value: true when useMNC=TRUE
1533    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1534      the ability (off by default) to read the grid information using MNC
1535    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1536    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1537    o do snap-shot diagnostics at the middle of the time-interval (instead of
1538      at the end).
1539    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1540      new test for AIM with thSIce + slab-ocean
1541    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1542    o move state variable diagnostics to the beginning of the time step ;
1543      (note: still needs some work specially for snap-shot diagnostics)
1544      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1545    
1546    checkpoint57c_post
1547    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1548    o generate new output.txt files on faulks with g77 & the new -ieee option
1549    checkpoint57c_pre
1550    
1551    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1552      update output.txt of exp. global_ocean.90x40x15
1553    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1554      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1555    o add saltFlux(+File) forcing capability with periodicExternalForcing
1556    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1557    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1558    o improvements for the MNC output from DIAGNOSTICS:
1559      - correct handling of the unlimitied dimension
1560      - all dims now have associated coordinate variables
1561      - variables located at U, V, and Corner ("Z") points are now written
1562        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1563        *all* data points are output
1564    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1565    o added pkg/seaice/seaice_monitor.F
1566    o mdsio_readfield.F can now read files visible only to master MPI process.
1567    o pkg/seaice: some test code for ice-modified ocean stress
1568    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1569      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1570      spurious negative numbers for precipitation and humidity.  Will cause
1571      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1572    o pkg/ctrl/
1573      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1574        May be enabled via doPackDiag
1575      *  introduce z-scaling of
1576         + gradient (doZscalePack) and
1577         + control (doZscaleUnpack)
1578    o pkg/mdsio/
1579      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1580      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1581    
1582    checkpoint57b_post
1583    o simplify options in diagnostics_fill arguments (remove weird combinations)
1584    o fix MNC coordinate variables so that they now contain per-face index
1585      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1586      general, EXCH2 grids are only aligned to a "local" coordinate system
1587    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1588    o Implement instantaneous output within pkg diagnostics:
1589      setting a negative frequency in data.diagnostics produces
1590     "snap-shot" output (as opposed to time-average if freq > 0)
1591    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1592      NOTE: change ptracer diagnostics name: use 2 characters to work with
1593            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1594    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1595      becomes the coordinate variable for the 'T' dimension
1596    o add CF-style coordinate variables to MNC
1597      - just a first cut:  numbers are meaningless on the cubesphere and
1598        missing along the T axis but otherwise it works!
1599    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
1600    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
1601    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
1602      this is based directly on what the model compute, so that the content of
1603      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
1604    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
1605    o clean up build options files for SunOS, in particular
1606      - remove -traditional from xmakedepend
1607      - change -xarch=v9 to -xarch=native for f77
1608      - restore use of make (not gmake)
1609      - add CC=gcc if using g77
1610    o changes per discussion of AM, JMC, & EH3 today:
1611      - move redundant "grid" variables out of "state" -- in preparation of
1612        creating proper CF-style coordinate variables and in recognition
1613        that any/all grid variables can be easily copied (eg. w/NCO) from
1614        the grid files into any of the other NetCDF files
1615      - *always* output grid variables with MDSIO (this will eventually be
1616        changed)
1617      - output MNC grid file if useMNC is true
1618    o every instance of _END_MASTER() has been found and replaced with
1619      _END_MASTER( myThid ) in order to satisfy certain picky Sun
1620      preprocessors
1621    o re-arrange diagnostics pkg initialisation:
1622     - allow each package to extend the available diagnostics list
1623     - add some checking and fix small problems (multi-threaded, ...)
1624     - new S/R diagnostics_fill (replace fill_diagnostics):
1625       look through the short list of active diag. (instead of the long list)
1626       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
1627    
1628    checkpoint57a_post
1629    o this set of changes restores TAMC compatibility
1630      tested for global_ocean.90x40x15 adjoint on trough
1631      (what a pain)
1632    
1633    checkpoint57a_pre
1634    o some modifs in tools/build_options for sunos
1635    o call ctrl_pack for ctrl at end for optimcycle=0
1636    
1637    checkpoint57
1638    o add horizontal bi-harmonic viscosity for vertical velocity
1639      - new parameter viscA4W (defaults to viscA4)
1640      - affects only non-hydrostatic code
1641      - to be done: no-slip lateral boundary conditions
1642    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1643    o implement Implicit Vertical advection for pTracers
1644    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1645      (implemented also for implicit vertical diffusion & advection)
1646    o OBCS: extend application of tracer open boundary conditions
1647      to a strip beyond the boundary of width Olx/Oly
1648    o add call monitor to TAF set of required calls (flow directives)
1649      and include in natl_box_adjoint
1650    o untangle a few ifdefs related to cost, ctrl, autodiff
1651      untangel a few ALLOW_ECCO_OPTIMIZATION
1652    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1653      (theta2, salt2 in ecco_cost_weights)
1654    
1655    checkpoint56c_post
1656    o OBCS as control variables
1657      - update ctrl_ad_diff.list, obcs_ad_diff.list
1658      - remove balance of obcs controls from default
1659      - fix index bug nobcs in ctrl_init
1660      - fix dummy fields filen in ctrl_pack
1661      - add dummy weights for obcs
1662    o lsopt: comment out fort.94 output
1663    o optim:
1664      - remove unnecessary header files
1665      - adjusted namelists
1666      - add xerbla.F to Makefile
1667    o exf:
1668      - multiple modifications of exf_check_range
1669      - unit change in exf_init_runoff from [m/year] to [m/s]
1670    o mdsio:
1671      - i/o-vector change debugLevel from debLevA to debLevB
1672    
1673    checkpoint56b_post
1674    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1675      is called from DO_THE_MODEL_IO
1676      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1677      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1678      - clean up PTRACERS_WRITE_TIMEAVE a little
1679    o add another verification experiment that tests both the cfc-pkg and
1680      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1681      reactive tendencies treated inline with regular timestepping
1682    o testreport previously did a lousy job of comparing small numbers, so
1683      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1684      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1685      testreport.
1686    o ptracers_monitor: bug fix for MPI
1687    
1688    checkpoint56a_post
1689    o GCHEM: finish reorganizating the package
1690      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1691        (introduces another 3D-array for each passive tracer, but only if
1692        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1693        gchemTendency is not needed because the timestep is done separately)
1694      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1695      - GCHEM is now---more or less cleanly---separate from PTRACERS
1696      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1697        so clear to me how that should be done in a general way.
1698    o CFC: improve formatting of output in CFC_ATMOS
1699    o PTRACERS:
1700      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1701        that ALL experiments with ptracers enable can be checked. This makes
1702        GCHEM_MONITOR obsolete.
1703      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1704        monitorFreq
1705      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1706    o add PTRACERS (PTR0[1-5]) to testreport output
1707    o exf_check_range:
1708      * default changed to .TRUE.
1709      * will check values for niter0 if debLevA, every timestep if debLevB
1710      * STOP in exf_check_range if 'out of range'
1711      * range chosen generous to allow for potential extema
1712      TBD: a version with stricter range
1713           permitted range would be runtime parameters
1714    o GMredi:
1715      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1716      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
1717      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
1718    o GCHEM:
1719      - move call to GCHEM_FORCING_SEP, so that it is now called before
1720        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
1721      - introduced a useGCHEM runtime flag and applied it everywhere.
1722      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1723        this flag is now only visible within GCHEM-pkg routines.
1724      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1725        be replaced by a 3D array that is computed before thermodynamics; for
1726        this, the tracer ID iTracer had to be included into the parameter list
1727        of ptracers_forcing
1728      - set up forward_step to call gchem_forcing, that will replace
1729        gchem_forcing_int in ptracers_forcing
1730      - cleaning up
1731    o small cleaning of exch2: remove files that are also in eesupp/src
1732    
1733    checkpoint56
1734    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
1735    o mnc: cleanup "full" files--fixes out-of-memory problem
1736    o ECCO-GODAE
1737      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
1738      * fully merged and updated from SIO code
1739        windstress sign change affects
1740        - exf_inscal_[u/v]stress
1741        - sign of xx_tau[u/v] adjustments
1742        - signs in cost_scat
1743      * ctrl_get_gen: avoid update of tau[u/v] for first few days
1744      * natl_box_adjoint updated and compressed
1745      * 2-level checkpoint switch added
1746        (tested in EXP. 1 of natl_box_adjoint)
1747      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
1748    o SVD
1749      * first complete, non-hacked version for SVD calculations
1750      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
1751        performed via direct access files admtlm_vector.it????
1752        (via ctrl_[un]pack)
1753      * optimcycle is used for ARPACK iteration counter
1754        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
1755      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
1756        and add linear transforms where necessary
1757      * controls are initial/final SST, SSS (can be extended; need to check
1758        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
1759    o mdsio: filename info to both stderr, stdout
1760    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
1761      from sign change
1762    
1763    checkpoint55j_post
1764    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
1765      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1766    o add consistent build directories and .cvsignore files to verification
1767    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
1768    o make all subroutines 30 or less characters in length for certain older
1769      compilers to work (a thorough search only turns up two routines in
1770      pkg/ptracers)
1771    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
1772      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1773    
1774    checkpoint55i_post
1775    o change arrays for total vertical diffusivity (2.D if explicit,
1776      3.D if implicit) ; each ptracer uses its own background value.
1777    o added mnc/NetCDF output capability to ocn_compon_interf
1778      - added bits to verification/cpl_aim+ocn so that it can run on
1779        ITRDA and other clusters without the mpirun "-wd" option
1780    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
1781      configuration
1782    o give MNC the ability to create additional files rather than
1783      exceeding a specified file size limit "MNC_MAX_FILESIZE"
1784      - the default is just less than 2GB which is a practical limit
1785        on many systems
1786    o Compute the non-local term using either KPP vertical diffusivity (=default)
1787       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
1788    
1789    checkpoint55h_post
1790    o add verification test "vermix"
1791    o remove all the *_ioinc flags and replace with the single global
1792      outputTypesInclusive flag
1793    o allow to set a vertical profile of vertical diffusivity for T & S
1794    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
1795    o useMNC moved from data.mnc to data.pkg
1796    
1797    checkpoint55g_post
1798    o Renaming carbon AD experiments to comply with testreport conventions
1799    o Updating adjoint of Held-Suarez hs94.1x64x5
1800    o Fixing directives for non-ECCO forward_step, after ECCO directives
1801      have been fixed to avoid recomp. of do_oceanic_phys
1802      Works well for global_ocean.90x40x15,
1803      but recomp. issue remains for carbon
1804    o Updating adjoint output for natl_box_adjoint after
1805      pkg/ecco has been modified (see taga c55d_post)
1806    
1807    checkpoint55f_post
1808    o rename to timeave_init_fixed
1809    
1810    checkpoint55e_post
1811    o some delicate re-shuffle of store directives to avoid one
1812      extra call of do_oceanic_physics
1813      affects ecco_the_main_loop.F, do_oceanic_physics.F
1814      checkpoint_lev1_directives.h
1815    o NB: this may break global_ocean adjoint temporarily,
1816      but it is clear how to fix it. Will do later, need this now.
1817    
1818    checkpoint55d_post
1819    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1820    o ecco_cost_weights is modified to 1x1 runs
1821    o modifs to allow observations to be read in as
1822      single file or yearly files
1823    o enable to read exf forcing fields as either
1824      single file or yearly files (flag useExfYearlyFields)
1825    checkpoint55d_pre
1826    
1827    o switch between 2-level and 3-level checkpointing
1828    o add ability of MNC to write local and "partial" (eg. 2D slices where
1829      the full 3D field is never actually stored) arrays to NetCDF files
1830      with the correct (that is, the complete multi-dimensional) set of
1831      array indicies
1832      - used in mom_vecinv() to write the diagFreq output
1833      - tested (demonstrated) in verification/aim.5l_cs
1834    o further mnc-ification
1835      - add verification/lab_sea to the list with mnc setups
1836      - fix undefined mnc v-names in cd_code
1837      - add kpp to mnc output (both snapshot and timeave)
1838    o non-hydrostatic code
1839      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1840        in calc_gw.F
1841      - defaults to viscAh
1842      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1843        friction or Leith) in non-hydrostatic mode, as long as there is
1844        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1845    o pkg/cost
1846      extend simple cost functions to treat time mean quantities
1847      (T,U,V) via cost_accumulate_state from cost_tile
1848    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1849        be 2 times larger than the minimum size the advection scheme requires.
1850        now get a perfect conservation of salt in advect_cs test-exp (updated)
1851    o GGL90 (Gaspar's TKE mixed layer)
1852      - add horizontal diffusion of TKE, requires exchanges in
1853        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1854        default. In OPA there is no horizontal diffusion of TKE but the
1855        mixing coefficients are computed from a horizontal average of TKE of
1856        6 points or so. I think that diffusion has a little more physical
1857        justification.
1858      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1859        was in vain)
1860      - mask tke-variable in ggl90_init
1861    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1862    o fix biharmonic diffusion on CS-grid.
1863    o more obcs stuff
1864      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1865        for reading boundary values. This routine is called from
1866        obcs_prescribe_read
1867      - updated obcs_check
1868      - changed sponge layer relaxation parameter units for days to seconds
1869      - turned off sponge layer by default
1870      - changed argument list of OBCS_CALC to myTime+deltaTclock
1871      - fixed about 35 bugs in obcs_external_fields_load
1872    
1873    checkpoint55c_post
1874    o obcs stuff
1875      - new runtime flags useOBCSprescribe, useOBCSbalance
1876      - re-arranged obcs_calc
1877      - moved exf_getobcs to obcs_prescibe_read
1878        obcs_prescibe_read is called after ORLANSKI stuff
1879        and independent of it (executable can contain all).
1880      - updated obcs_check
1881      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1882        These may be necessary only if tangential velocities are
1883        prescribed at OB, not sure, needs testing.
1884    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1885      which simplifies the calls and passes the ifc check-bounds test
1886    
1887    checkpoint55b_post
1888    o add a 2D scalar, Z location, exchange_2 routine.
1889    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1890      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1891      affects advect_cs results (for the wrong reason): update output.txt
1892    o use a more standard discretization for biharmonic viscosity ;
1893     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1894      affects results of dome set-up: update output.txt
1895    o fix gad_advection.F (CubedSphere part), back to version 1.23
1896    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1897    
1898    checkpoint55a_post
1899    o merged code to
1900      * prescribe/read time-dependent open boundaries
1901        (works in conjunction with exf, cal)
1902      * sponge layer code for open boundaries
1903      * each boundary N/S/E/W now has its own CPP option
1904        (healthy for the adjoint)
1905    
1906    checkpoint55
1907    o up-to-date adjoint of previous breaks
1908      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1909      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1910      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1911      - carbon: * remove tr1-related adjoint verification
1912                * add ptracer as control variable
1913    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1914      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1915    
1916    checkpoint54f_post
1917    o in verification/carbin/ remove experiment related to
1918      ALLOW_PASSIVE_TRACER (array tr1 etc)
1919      code_ad/ input_ad/ results_ad
1920    
1921    o add two new packages
1922      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1923        + subject to optimization (memory)
1924      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1925        + subject to reordering (many GOTOs in the original code)
1926        + so far opps is called for every (i,j) point, and then operates in
1927          the vertical; one may want to reorder the scheme in order operate in
1928          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1929          fields)
1930    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1931      - all verification tests compile and run with linux_ia32_g77
1932      - defaults are compatible with current input files--nothing
1933        should change if you were not previously using MNC
1934      - MNC output has been added in numerous places (eg. timeave)
1935        but there are still a few writes not yet do-able with MNC
1936        (this is in progress)
1937      - flags now allow for either/or/both use of MDSIO and MNC and
1938        documentation will soon follow
1939      - numerous small formatting cleanups for ProTeX
1940    o add version info (via BUILD_INFO.h) to MNC and stdout
1941    
1942    checkpoint54e_post
1943    o add two new packages
1944      - pp81 (Packanowski and Philander, 1981), Richardson number and
1945        stratification dependent mixing
1946      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1947      - these scheme operate in a similar manner as KPP (without ghat, of
1948        course), however there is only one diffusivity that is used for both
1949        temperature and salinity (and passive tracers)ç
1950    o add offline package
1951    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1952      provided by Stephanie Dutkiewicz
1953    o genmake2: add ability to search for C compilers and cleanup test output
1954      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1955    
1956    checkpoint54d_post
1957    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1958    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1959      leading to additional shift by 5 days each year of integration
1960       (i.e. leading to considerable offset over the years)
1961    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1962    o start with no AB and no initial filtering (staggerTimeStep):
1963      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1964    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1965      (external loading & cpl import/export stay in forward_step.F)
1966    o update coupling interface to work with new staggerTimeStep
1967    o change MDSIO ptracers_pickup.
1968    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1969    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1970    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1971    
1972    checkpoint54c_post
1973    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1974      this affects (truncation error) output.txt of test-exp:
1975       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1976    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1977    o change Qnet to always be the net heat flux, (+upward).
1978      affects (truncation error) output of natl_box exp.: updated
1979    o define the max number of passive tracers in PTRACERS_SIZE.h
1980    o start to test mnc routinely in exp0
1981    o add sea-ice loading (sIceLoad) as a new forcing field.
1982    
1983    checkpoint54b_post
1984    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1985       impressive on Altix and Opteron systems)
1986    o diagnostics can now write NetCDF files through the mnc package
1987    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1988    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1989    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1990      affects (truncation error) output of lab_sea & natl_box exp.: updated
1991    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1992    
1993    checkpoint54a_post
1994    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1995    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1996    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1997    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1998      + internal_wave (shift in writing cg2d_ini_res)
1999    checkpoint54a_pre
2000    
2001    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
2002      - modified verification/lab_sea and natl_box_adjoint accordingly
2003    
2004    checkpoint54
2005    checkpoint53g_post
2006    o prepare splitting of thermodynamics: store convect.counter in common block
2007    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
2008      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
2009    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
2010    o new parameter "nShapS": allow to treat differently S from T (nShapT)
2011    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
2012    o restore adjointability
2013    
2014    checkpoint53f_post
2015    o modifications that affect AIM experiment results (update output.txt):
2016      - no advection of S at top interface Nr (pkg/generic_advdiff)
2017      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
2018    o AIM pkg:
2019      - include stability function into surf.Flux derivative relative to Tsurf
2020      - calculate clear-sky radiation & surface temp. change (for diagnostics)
2021    
2022    checkpoint53e_post
2023    o merged cylindrical coord configuration
2024    o added rotating_tank experiment
2025    checkpoint53e_pre
2026    
2027    checkpoint53d_post
2028    o faulks upgraded: re-generate output.txt that have changed:
2029       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
2030    o Added Bryan and Lewis, 1979, vertical diffusivity profile
2031    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
2032    o added Sadourny discretization of Coriolis
2033      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
2034      - re-enabled use of omega3 (useAbsVorticity)
2035    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
2036      vector-invariant equations
2037      - note: does *NOT* yet use same variable visc. for no-slip BC's.
2038    o recoded the lateral boundary conditions for non-hydrostatic w, this time
2039      hopefully without new bugs
2040      - still to do: biharmonic friction for non-hydrostatic w
2041    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
2042    o regenerated output for global_ocean_ebm (using -ieee)
2043    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
2044      of mom_common/
2045      - simple re-arrangement of instructions within computing loop
2046    checkpoint53d_pre
2047    
2048    checkpoint53c_post
2049    o new version of coupler for AIM+thSIce and Ocean models
2050     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
2051     - land: change Evaporation of snow
2052     - aim with thSIce: fix bug in snow-precip.
2053    o changes to calc_gw.F
2054     - bug fix for w^2 term near the bottom boundary
2055     - (hopefully) improve the lateral slip boundary condtions for use with
2056        partial/looped cells
2057      - because the bug fix changes two verification experiments anyway (exp5
2058        and plume on slope), change the lateral boundary condition from half slip
2059        to the value of no_slip_sides
2060    o ebm package wasnt quite up to the parallel task. Fixed that.
2061    o Adjoint of EBM package + verification
2062      * TLM OK
2063      * ADM not sufficient accuracy yet (needs further testing)
2064    
2065    checkpoint53b_post
2066    o Commiting new energy balance model to repository
2067      * package is pkg/ebm
2068      * verif. is verification/global_ocean_ebm
2069      * references are in ebm_driver.F
2070    C      * X. Wang, P. Stone and J. Marotzke, 1999:
2071    C        Global thermohaline circulation. Part I:
2072    C        Sensitivity to atmospheric moisture transport.
2073    C        J. Climate 12(1), 71-82
2074    C      * X. Wang, P. Stone and J. Marotzke, 1999:
2075    C        Global thermohaline circulation. Part II:
2076    C        Sensitivity with interactive transport.
2077    C        J. Climate 12(1), 83-91
2078    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
2079    C        Destabilization of the thermohaline circulation
2080    C        by atmospheric eddy transports.
2081    C        J. Climate 7(12), 1870-1882
2082    o Will need long integration testing.
2083    checkpoint53b_pre
2084    
2085    o created pkg/mom_common in preparation for variable viscosity code
2086    o renamed and split ini_mnc_io
2087    o pkg/land: only liquid water can diffuse or run-off
2088    o AIM using land: soil wetness availability account for snow
2089    o added printMapIncludesZeros to EEPARMS namelist
2090    
2091    checkpoint53a_post
2092    o restore TAMC compatiility for exf_constants.h
2093      (no usage of _d in .h)
2094    o Additional storing in KPP in an attempt to fix
2095      TAMC problem with adjoint of KPP code.
2096      (no success...)
2097      Identical code works fine with TAF.
2098    o Fixed verification/natl_box_adjoint experiments.
2099      Initial conditions for Experiments 4 and 5 are now
2100      set to "SEAICE_initialHEFF=0", which is more reasonable,
2101      and hence gives results closer to that of Experiment 2.
2102      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
2103    
2104    checkpoint53
2105    o stable checkpoint with up to date adjoint
2106      TLM tests only run for 1st grdchk at the moment. Its unclear if
2107      this is a code problem or a problem with resetting code for g_
2108      variables that is being autogenerated wrong.
2109      Otherwise:
2110       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
2111       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
2112         are both still in chaos following their security messes.
2113    
2114    checkpoint52n_post
2115    o various build (mostly genmake2) changes including:
2116      - ability to build/run more easily within Cygwin and MacOS X
2117      - more complicated Makefiles with a stronger dependence on Gnu Make
2118    o pkg/seaice modifications
2119      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
2120        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
2121        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
2122      - changed proxy for geostrophic velocity and updated
2123        verification/lab_sea/results/* accordingly
2124      - removed ADI dynamic solver from pkg/seaice
2125      - replaced all occurrences of 1/CSTICE or 1/CSUICE
2126        they caused a segmentation fault under certain circumstances
2127      - removed unused field WATR
2128    o bug fix in exf-package:
2129      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
2130         now reflect that.
2131    o small fixes in the cal-package:
2132      - set reference date to first of January for the 'model'-calendar
2133      - failing of cal_CheckDate in cal_FullDate now actually results in a
2134        warning
2135    o small modifications in exf-package to increase flexibility:
2136      - change climtempfreeze from a constant to a runtime parameter that
2137        is specified in data.exf_clim (default = -1.9)
2138      - introduce runtime parameter windstressmax (default = 2.0) that is
2139        specified in data.exf
2140    o fix in pkg/thsice:
2141      - update Evap (Tsf changes) to be consistent with Latent heat flux
2142      - maintain snow precipitation unchanged (even if Tsf >=0).
2143     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
2144    
2145    checkpoint52m_post
2146    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
2147      this does not change any of the results, because myIter=0 in swfrac always
2148      lead to jwtype=2 (the default anyway), but the call makes little sense
2149      as a default
2150    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
2151    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
2152      atmospheric model (AIM) to use it ; add a "slab ocean" component.
2153    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
2154    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
2155    o extending useSingleCpuIO option to work with new exch2 I/O format
2156      - old-style, missing-tile I/O is still accessible by defining CPP
2157        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
2158    o monitor package can write to NetCDF files and/or STDOUT
2159    o fix re-definition bug in MNC_GRID_INIT_ALL()
2160    o doc/api_reference added
2161      - a framework for building an API Reference Manual using all
2162        the "protex" comments embedded in the code
2163      - see pkg/generic_advdiff, pkg/mnc for examples
2164    o MNC:
2165      - make myThid the last argument for all subroutines
2166      - new default for the grid files: NO halos
2167      - add useMNC and other run-time flags
2168      - separate per-file-group handling of the unlimited dimension
2169      - early initialization of MNC w/ flags read at the eeboot stage
2170        and lookup tables set in initialize_fixed
2171      - write all MNC output to a freshly-created directory
2172    o thermodynamics sea-ice (thsice) is now tested with testreport.
2173    o test exp. advect_cs: use the standard cs32 grid ; update output.
2174    o Added functionality to grdchk:
2175      pick global i,j,k position (or nearest wet) where to perform check.
2176    
2177    checkpoint52l_post
2178    o new land formulation:
2179      a) use ground enthalpy as prognostic variable to ensure exact
2180         energy conservation.
2181      b) account for water temperature and for latent heat of freezing
2182         in all processes (rain, run-off, ground storage)
2183      c) compute surface and ground temperature implicitly.
2184    o aim_v23 modification for new land model:
2185      a) Treat separately land / ocean / sea-ice surface fluxes
2186         to allow implicit computation of land & sea-ice surface temp.
2187      b) add snow precipitation.
2188    checkpoint52l_pre
2189    
2190    o fix problem (when 1 tile is empty) in min/max monitor.
2191    o fix bug in timeAve (u,vZetatave in common block)
2192    o no restoring terms under ice for pkg/seaice
2193    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
2194    o bug fix for pkg/seaice pickups
2195    o change MNC call locations and add coordinate attributes
2196    o mask vorticity at the corner ; affects global_ocean.cs output
2197    o fix ini_curvilinear_grid ; test CS experiments with mpi
2198    o aim.5l_cs: modify sea-ice fraction input file ; update output
2199    o exf: Adding simple range check routine for exf fields after read
2200    
2201    checkpoint52k_post
2202    o removed top-level directory "diags"
2203      - we migrated these functions to pkg/timeave a long time ago
2204    o fixed bug introduced in pkg/monitor
2205    o accuracy ctrlprec = 32 insuffient for gradient checks using
2206      averaged fields (I/O via cost_averages)
2207      -> use ctrl.h in active_file*.F to control I/O precision.
2208    o paramter list of CALL ADTHE_MAIN_LOOP
2209    o added initial do_the_model_io to ecco
2210    o set all ...Freq to zero after cost_final
2211      taveFreq, dumpFreq, pChkptFreq
2212    o MAIN and ECCO differentiability restored
2213    
2214    checkpoint52j_post
2215    o fix nchklev in tamc.h for global_ocean...
2216    o Bringing flow and store directives up-to-date
2217    o Really weird thing!
2218      call do_the_model_io from the_main_loop with parameters
2219      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
2220      TAF places a faulty re-call of initialise_varia
2221      after cost_final call which should not be there!
2222    checkpoint52j_pre
2223    
2224    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
2225      error messages
2226    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
2227    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
2228      debug output
2229    o modfied mdsio_writefield.F to handle non-global files under exch2
2230    o update AIM Cubed-Sphere exp (aim.5l_cs):
2231      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
2232    o update AIM Equatorial Channel exp:
2233      use standard aim_v23 pkg and change the SST fields to be more realistic.
2234    o globalFile now works with exch2
2235    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
2236      mon_vort3.F to make exch2 friendly with >1 tile per cube face
2237    o limit timeave output for hi-res integrations
2238    
2239    checkpoint52i_post
2240    o removed CPP_EEOPTIONS.h from verification/*/code
2241    o updated the tiling for global_ocean_pressure
2242    checkpoint52i_pre
2243    
2244    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
2245      the old pkg/aim).
2246    
2247    checkpoint52h_pre
2248    o shortened offending lines in exch2_send_rx?.template
2249    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
2250    o genmake2: add build & execute test for NetCDF code
2251    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
2252      old grid files, moved CPP_EEMACROS.h to pkg/exch2
2253    o added useSingleCPUIO flag to monitor.F and mon_out.F
2254    o added temporary hack for sea-ice dynamics on the cube:
2255      metric terms are ignored and it is assumed that
2256      there is no sea-ice on cube faces 1, 2, 4, and 5.
2257    
2258    checkpoint52f_post
2259    o added exch2 cube routines to pkg/exch2
2260    o modified hs94.cs-32x32x5 to use it
2261    o added new grid files to hs94.cs-32x32x5
2262    checkpoint52f_pre
2263    
2264    checkpoint52e_post
2265    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
2266      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
2267    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
2268      to work with implicit vertical advection and AB ;
2269    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
2270    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
2271     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
2272    checkpoint52e_pre
2273    
2274    o fix bug in impldiff when Nr=1 or Nr=2.
2275    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
2276    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
2277    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
2278      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
2279    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
2280    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
2281    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
2282    
2283    checkpoint52d_post
2284    o re-tiled many expts to allow comparison in multi-processor mode
2285      - updated output accordingly
2286      - changed hs94.128x64x5 to use intial T from file rather than use the
2287        random number generator
2288    o add infrastructure in model routines for fizhi and gridalt packages
2289    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
2290    o changes to permit hi-res, cubed-sphere, configuration
2291      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
2292      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
2293      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
2294        of surface winds for the cube
2295      (A verification experiment, based on global_ocean.cs32x15, but with
2296       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
2297       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
2298       complete with example surface forcing files and matlab scripts to look
2299       at the output and compare it with that of global_ocean.cs32x15.)
2300    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
2301       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
2302       to conform to the common rule.
2303    o check-in the first version of the coupler + interfaces for multi-components
2304       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
2305       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
2306       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
2307       - ocean and atmos. share the same horizontal grid (no interpolation).
2308       - exchanges between component and coupler is done in forward_step
2309    o new verification experiment, cpl_aim+ocn:
2310       coupled ocean - AIM atmosphere on cs32 grid.
2311    
2312    checkpoint52d_pre
2313    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
2314    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
2315    
2316    checkpoint52c_post
2317    o Fixing OPTIONS files for use of exf:
2318      - ALLOW_ECCO not needed
2319      - ECCO_CPPOPTIONS.h should not be included from
2320        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
2321        as has been the case in the past
2322      - All cal/exf related options are currently set in
2323        single header file. Should remain so until we
2324        agree on a consistent new policy.
2325    o Removed all CPP options for cal package.
2326      cal has no more CPP options.
2327    o modified STOREs in GAD_ADVECTION
2328    o corrected key comp. for passkey
2329    
2330    checkpoint52b_post
2331    o new version: "thsice" of thermodynamic sea-ice pkg:
2332     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
2333     - modify fluxes but do not change theta directly;
2334     - light cleaning of bulk_force pkg (still needed with thsice).
2335     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
2336       + output_thsice.txt to test thsice & bulk_force pkgs.
2337    o put back grid & coriolis monitor output.
2338    checkpoint52b_pre
2339    
2340    o call "do_the_model_io" at the beginning (=> dump initial state)
2341    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
2342    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
2343      (need info on NUMBER_OF_PTRACERS)
2344    o missing PTRACERS headers in some routines
2345    o default tamc.h in pkg/autodiff supposed to crash
2346      to ensure proper customization
2347    
2348    checkpoint52a_post
2349    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
2350      - moved surfaceTendencyTice from pkg/seaice to main code
2351      - subroutine FREEZE_SURFACE now limits only surface temperature
2352        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
2353        => new output.txt for global_ocean.cs32x15 & global_with_exf
2354      - keep the old version of FREEZE for backward compatibility;
2355        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
2356      - corresponding modifs for TAF directives
2357    o added surface flux output variables to TIMEAVE_STATVARS
2358    o time-averaged output for pkg/ptracers
2359    o fix problem with ECCO-related divided adjoint
2360      snapshot file was missing some ad-variables,
2361      but no warning issued by TAF
2362    
2363    checkpoint52a_pre
2364    o some bug fixes for #undef REAL4_IS_SLOW
2365    
2366    checkpoint52 = ecco_c52_e35
2367    o after testing adjoints of checkpoint51u_post
2368    
2369    checkpoint51u_post
2370    o this is the post-merge tag of the ecco-branch
2371      (needs another clean checkout and re-testing)
2372    o various natl_box_adjoint configs and results
2373      but no input fields
2374    o obcs adjoint not yet merged!
2375    o adding ECCO global 1x1 and 2x2 degree configs
2376    o updated/extended some store directives for seaice
2377    o pkg/ecco now containes ecco-specific part of cost function
2378    o top level routines the_main_loop, forward_step
2379      supersede those in model/src/
2380      previous input data.cost now in data.ecco
2381      (new namelist ecco_cost_nml)
2382    o in ctrl/ cleaned some cross-dependencies and updated CPP options
2383    
2384    checkpoint51t_post
2385    o this is the pre-merge tag of the ecco-branch
2386    
2387    checkpoint51s_post
2388    o cleanup: removed various obsolete #define-s
2389    o pkg/grdchk
2390      - renamed 'ph-grd 3' to 'grad-res'
2391      - merged from ecco-branch
2392        (remaining bug fixes for obcs gradient checks)
2393      - additional high-precision output for testreport
2394        (grep for 'precision_grdchk_result')
2395    
2396    checkpoint51r_post
2397    o cleaned up or removed CPP_OPTIONS.h files
2398    o updated results for some of the tests to reflect the new
2399      optfiles (-ieee: -O0 instead of -O3)
2400    
2401    checkpoint51q_post
2402    o cd_code:
2403      - moved cd_scheme.F -> cd_code_scheme.F
2404      - separate read_checkpoint from cd_code_ini_vars.F
2405      - separated cd_code part from write_checkpoint
2406      - updated AD_SOURCE, generated .flow
2407      - added CD_CODE_VARS.h to the_main_loop
2408      - Moving cd_code specific store dir.s to pkg/cd_code
2409    o ctrl package totally restructured
2410      - pack/unpack now optional and decoupled from
2411        xx_/adxx_ I/O
2412      - ctrl_pack/unpack cleaned
2413        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
2414      - confined inclusion of AD_CONFIG.h to where necessary.
2415    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
2416    
2417    checkpoint51p_post
2418  o create initial cd_code package  o create initial cd_code package
2419      - WARNING: the initialization of fields within packages
2420        is broken because INI_FIELDS (where READ_CHECKPOINT is
2421        called) is called *before* PACKAGES_INIT_VARIABLES.
2422        This seems to be backwards since
2423        1) its important to initially zero the entire field including
2424           the "halo" region
2425        2) zeroing needs to be done *before* reading pickup info
2426           and the pickup call might or might not happen in any
2427           particular run
2428      - this needs an overhaul for R2
2429  o cleanup verification/*/code/GMREDI_OPTIONS.h  o cleanup verification/*/code/GMREDI_OPTIONS.h
2430  o cleanup testreport  o cleanup testreport
