5      ==============================      ==============================
6    
7    o Refresh tutorial_global_oce_biogeo, notably:
8      - change bathymetry (put back seamounts in ACC, use hFacs)
9      - change EOS (POLY3 --> JMD95Z)
10      - use Bryan-Lewis vertical diffusivity
11      - use multidimensional advection
12      - remove old virtual virtual in dic pkg, now done through ptracer pkg
13      - change a couple of parameters in dic pkg
14    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
15    o pkg/obcs: change default to OBCSfixTopo = .true.,
16      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
17      - replace "debugMode" with "debugLevel .GE. debLevB"
18    o implementation of TAF directives for gchem,cfc,dic
19    o remove "exp5" (replaced by tutorial_deep_convection).
20    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
21      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
22      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
23      --> changes results in exp4, seaice_obcs
24    o tutorial_deep_convection :
25      update the set-up and increase resolution and domain size ; start
26      from pseudo initial conditions = output at t=120mn in order to see
27      something happening when running testreport.
28    o pkg/seaice: add os7mp as an advection scheme
29                  add check for advection schemes
30                  add a flag for restoring T and S underneath sea ice
31    o pkg/my82: add netcdf-support and diagnostics
32    o thsice pkg:
33      - Now hsMax limits snow height by turning it into ice following
34        flooding scheme (and now conserving energy)
35      - Slight rewriting of the formula in thsice_calc_thick.F
36      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
37      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
38    
39    checkpoint59p
40    o gchem / dic / cfc :
41      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
42      - add new parameter files: "data.dic" & "data.cfc" ;
43      - various re-arrangement in initialisation & header file ;
44      - fix tutorial_global_oce_biogeo for multi-threaded test.
45    o pkg/dic: test for "pickup_dic" file when restarting ;
46      if no pickup-file, can restart with a re-initialised pH (same as it did
47      before) providing pickupStrictlyMatch is set to False.
48    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
49      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
50    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
51      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
52    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
53     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
54       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
55    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
56       scheme to use for vorticty-term ;
57     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
58       (with default selectVortScheme, return to original discretisation)
59     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
60    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
61    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
62      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
63      also fix diagnostics VISCAHW & VISCA4W.
64    
65    checkpoint59o
66    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
67    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
68      move a few statemens out the main loop into separate loops
69    o pkg/shelfice:
70      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
71        (kg/m^2/s), does not break tests, because in verification/isomip,
72        rhoConstFresh=rhoConst (by accident)
73      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
74      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
75        new file model/src/seawater.F, so that they are available for all pkgs.
76      - convert potential temperature into in-situ temperature. This changes the
77        isomip tests => update tests
78    o add a flag writePickupAtEnd (default=true) to be able to suppress
79      writing a pickup at the last timestep
80    o tools/mpack-1.6 :
81      - disable automake (not working) and autoconf (not needed).
82      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
83        also cleaner with much less compilation warnings.
84    o pkg/profiles:
85      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
86      (for "less than 32 characters name" compiler requirement)
87    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
88      conditions that have a different sampling frequency than S/T/U/V obcs
89    o pkg/diagnostics (stats-diags):
90      - fix global Min/Max in case 1 processor get only empty tiles
91    o genmake2: replace (4 times)
92         make genmake_tc_1.o >> genmake_warnings 2>&1
93      with
94         COMM="$CC $CFLAGS -c genmake_tc_1.c"
95         echo $COMM >> genmake_warnings
96         $COMM >> genmake_warnings 2>&1
97      to make genmake2 always see the value of CC as specified in the optfile.
98    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
99      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
100      - modify verification advect_cs test to test SOM-advection on CS-grid.
101    o pkg/ctrl:
102      - Rewrite of ctrl_map_ini_ecco.F,
103        introducing a generic routine (ctrl_map_ini_gen.F).
104      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
105    
106    checkpoint59n
107    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
108      number in dedicate array "hdiag":
109      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
110        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
111      - many small changes (integer format) for large number of diagnostics
112      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
113        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
114    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
115      usingSphericalGrid, this allows to define the rotated grid coordinates
116      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
117      geographical coordinates according to the inverse of the rotation defined
118      by the Euler angles, so that Coriolis parameter and online-interpolation by
119      exf works with the geographical coordinates on XC/YC/XG/YG.
120      Naturally, this feature does not work with all packages, so some
121      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
122      profiles), because there the coordinates are assumed to be regular
123      spherical grid coordinates.
124    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
125      - introduce isopycnal diffusion coefficient control.
126    o tools/adjoint_options:
127      - additional control vector components.
128    o pkg/mnc: have mnc create marginally meaning full coordinate variables
129      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
130    o pkg/mypackage:
131      - add example of read/write pickup for state-var ;
132      - add entry points to the main code for state-vars diags & write-pickup.
133    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
134      transitions for useExfYearlyFields
135      - add new subroutine that determines the file to read from for
136        use*YearlyFields = .TRUE. and .FALSE.
137      - add a verification experiment to global_with_exf that tests
138        useExfYearlyFields with USE_EXF_INTERPOLATION defined
139    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
140      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
141      subroutines (which could be generated from a template, because they are
142      almost identical), for now they are included in obcs_prescribe_read.F for
143      simplicity
144    o pkg/exf:
145      - add a little more diagnostic to exf_interp_read (in analogy to
146        mds_read_field, can be turned off with debugLevel < debugLevA=1)
147      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
148        ugly but fast by unrolling short inner loops, inserting a unroll=8
149        directive in routine lagran, and splitting a loop and making do while the
150        outermost loop (the latter requires the intoduction of index arrays)
151    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
152    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
153      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
154    o verification/seaice_obcs: updated for restart test and latest options
155    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
156      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
157      for now this is only available for the C-grid code and also within
158      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
159    
160    checkpoint59m
161    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
162      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
163    o gad_som : fix flux output (& diagnostics) to have same units as other  
164      advection scheme fluxes (was previously multiplied by deltaT).  
165    o added verification/seaice_obcs both to test seaice open boundaries
166      and to provide an example matlab scrpt for generating them
167    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
168    o pkg/salt_plume: clean up salt_plume_frac.F to
169      remove redundancy in PlumeMethod 1 and 4
170    o pkg/kpp: added saltplume diagnostics
171    o pkg/obcs and pkg/seaice:
172      - do not set uice and vice to zero when OB*icefile are unspecified
173      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
174      - moved seaice tracer obcs after call to seaice_growth
175    o pkg/salt_plume: added various options for salt plume depth
176      criterion and for vertical distribution of the salt
177    
178    checkpoint59l
179    o pkg/ptracers: new version of ptracers pickup:
180      read meta file and write only fields which are needed to restart.
181      ( same logic as main pickup file ; also using pickupStrictlyMatch )
182    o pkg/seaice:
183      - add timescale for melting due to warm mixed layer as a means of
184        setting SEAICE_availHeatFrac more conveniently
185      - add a CPP-flag/runtime parameter check for flooding algorithm
186      - reformulated availHeat in seaice_growth.F to be independent of AREA
187    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
188      unit changes
189    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
190    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
191      SX vector computer.
192    o pkg/seaice:
193      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
194        seaice forcing fields can now be read only through pkg/exf
195      - removed some unused halos
196    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
197    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
198      or U/VICE from U/VWIND before computing U/VSTRESS
199    
200    checkpoint59k
201    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
202      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
203    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
204      all experiments pass when compile with un-initialised var. checking option.
205    o added pkg/salt_plume
206    o script to test restart (for now, in MITgcm_contrib/jmc_script)
207    o pkg/seaice: new read/write pickup version.
208      read meta file and write only fields which are needed to restart.
209      ( same logic as main pickup file ; also using pickupStrictlyMatch )
210    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
211    o lab_sea.hb87: modify the domain & update output.hb87.txt :
212      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
213      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
214      process. Fixed here by closing the domain at the Northern boundary.
215    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
216    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
217      a set of consecutive levels in/from a 3-D array.
218    o pkg/ptracers:
219      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
220      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
221    
222    checkpoint59j
223    o in pkgs: dic, obcs, offline, rbcs:
224      standard way to compute coeff. for time interpolation between 2 time reccords
225      which retains full precision (& make results less dependent on compiler).
226      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
227    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
228      packages instead of reading ice cover and wind speed separately
229    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
230     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
231      to allow to compile customized code before the update)
232    o cleaning-up:
233      - fix CPP instruction syntax in pkg/obcs
234      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
235        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
236      - fix some threads issue in IO parts.
237    o pkg/dic:
238      - add tons of "_d 0" (--> much better testreports !)
239       and then update outputs of tutorial_global_oce_biogeo
240    o pkg/mom_fluxform:
241      add a special version of momentum advection intended to conserve momentum
242      next to a bathymetry step or a coastline edge. (default = off = #undef)
243    o new read/write pickup version:
244      - for now, only implemented for main (mdsio) pickup file.
245      - write out only what is needed to restart; merge pickup_nh , pickup_ph
246        and main pickup together.
247      - read meta file; read only what is needed to restart; stop if a field
248        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
249        if it make sense (even if the restart is not perfect).
250      - if no meta file, assume that pickup to read corresponds exactly to
251        a pickup that would currently be written.
252      - read pickup written in the old format (until checkpoint59i) if it
253        recognizes an old meta file (no field-list).
254      - add a meta file in exp. which starts from a pickup: 2 cases:
255        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
256         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
257        b) a meta file describing the content of the associated pickup file
258         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
259    o pkg/mdsio & pkg/rw:
260      - new routine to read a meta file ; new set of routine to read
261        Multiple-fields file (with meta file).
262    o added open boundary conditions capability for seaice
263        HSNOW, HSALT, UICE, and VICE
264    
265    checkpoint59i
266    o adjoint:
267      * fix multiDimAdvection adjoint
268        (partial recomputation problem by TAF for fVerT(:,:,kDown)
269        and comlev1 size definition (maxpass vs. max. number of tracers)
270      * verification/global_ocean.90x45x15 adjoint now tests
271        NLFS and multiDimAdvection using DST3 (=30)
272      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
273    o pkg/kpp: add "_d 0" to real constant (if missing);
274      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
275      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
276    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
277      for internal parameters related to restart process (formerly from PARAMS.h)
278      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
279    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
280      as argument. (only atm2d & obcs write_pickup have not yet been updated)
281    o pkg/monitor:
282      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
283      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
284      - account for deep Atmosphere factor and density factor (anelastic)
285    o added open boundary conditions capability for seaice HEFF and AREA
286    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
287      thermodynamics
288      - requires a little reorganization, which affects the testreport results
289        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
290        so that now the conservative form is tested
291      - add a few comments
292    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
293    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
294    o add new diagnostics to seaice: advective, diffusive fluxes (only for
295      multidim-advection, for scheme 2 they are not filled) and transports,
296      thermodynamic growth rates
297    o change units of EmPmR (inside the code, + within coupling interface)
298      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
299      Affects results @ truncation level (cg2d match) and update output of
300       experiments: lab_sea(6), global_ocean.90x40x15(10),
301      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
302      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
303      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
304      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
305    
306    checkpoint59h
307    o pkg/exf:
308      - improve vectorization by moving if-statement out of loops in
309        exf_mapfields, exf_radiation
310      - exf_bulkformulae.F: introduce 2D fields and vectorize code
311    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
312    o testreport:
313      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
314        monitor & update offline_exf_seaice exp. output.
315      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
316    o pkg/seaice:
317      - bug fix in the evp solver: boundary conditions were affected be
318        masking of zMax/zMin (changes results)
319      - minor bug fix in boundary conditions in seaice_calc_strainrates
320        (changes results for no_slip)
321      - seaice_lsr.F: make interpolation of eta dependent on boundaries
322      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
323      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
324        stress formulation and no-slip boundary conditions
325    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
326      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
327    o pkg/seaice: a first HSALT time stepping equation has been checked in
328    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
329      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
330      without requiring DO-IF statements
331    o pkg/thsice:
332      use continuous power-law function for partition of energy between lateral
333      melting/freezing and thinning/thickening ; old code using step function
334      still available with #undef THSICE_FRACEN_POWERLAW
335      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
336    o testreport: change AD testing : check against results/output_adm.txt
337      using same scripts as for forward test.
338    
339    checkpoint59g
340    o adjoint testing: in preparation for changing testreport:
341      - output format: cost and grad written on separated lines
342      - ad output results in directory "results" (instead of "results_ad")
343    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
344    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
345    o pkg/ecco: allow user defined cost function contributions
346    o testreport:
347      Allow to choose (per experiment) the list of tested output variables
348       and the main variable (used to issue a pass/FAIL ) ;
349      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
350      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
351      Also modify printing of summary:
352       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
353       b) echo the list of tested variables in the individual summary.txt of
354          each experiment.
355    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
356      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
357      (but still depend on the tile decompostion of the domain).
358    o pkg/seaice: change a discretization detail to make the B-grid code
359      "more symmetric". This change is likely to remove all "ridges/leads" that
360      where quasi-aligned with the grid in B-grid solutions. It may also be
361      the solution to the stress coupling issues with the B-grid.
362    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
363      remove .cvsignore from input dir. (since testreport no longer run here).
364    o pkg/thsice:
365     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
366     - fix reshaping of sea-ice just after advection:
367       melt all the ice only if ice-volume is too small.
368     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
369       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
370     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
371    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
372      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
373    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
374      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
375      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
376      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
377      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
378      -> update output.txt
379    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
380     this affects truncation error: -> update output.txt of exp:
381      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
382      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
383    
384    checkpoint59f
385    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
386    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
387      a bounded range (in forward mode)
388    o pkg/ecco, ctrl, autodiff and mom_common:
389     internal parameter controls, completements of implementations
390    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
391    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
392      (not seem any difference in testing results).
393    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
394       at face corners.
395    o pkg/generic_advdiff:
396     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
397      loop range indices for computing vertical advection tendency
398      and do the calculation in the interior only (no overlap) ;
399      for now, only implemented for SOM advection (to save CPU time).
400     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
401    o exch2 adjoint
402      First set of changes:
403      - add exch2 hand-written adjoint templates
404      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
405        This will require cleanup in pkg/autodiff/*.F
406        (changed routines currently kept separate in verif. code/)
407      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
408        that used to hide exch2 or cubed-sphere specific code
409        (commented via 'cph-exch2')
410    o pkg/seaice
411      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
412    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
413       output of global_ocean.cs32x15.thsice .
414    
415    checkpoint59e
416    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
417      for B-grid vector (not yet tested) and C-grid vector (<- only used
418      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
419    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
420      (#ifdef ALLOW_SALT_PLUME)
421    o gather_2d/scatter_2d: removed halo regions
422    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
423      scheme and the corresponding test case (under front_relax dir). For now,
424      only available with Skew-flux form and not yet tested in realistic set-up.
425      adjoint: store directives updated, but gradient checks deteriorated,
426      so maybe GM/Redi adjoint is now broken.
427    o seaice adjoint
428      * add AREA, HEFF, HSNOW as control variable
429        (should not change lab_sea results)
430      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
431    o pkg/seaice:
432      * added computation of saltFlux in seaice_growth;
433        For time being, sea ice salinity is assumed constant
434        contribution of snow flooding to freshening of sea ice is neglected.
435        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
436        defaults to 0.0 in order to maintain backward compatibility.
437        Typical values for SEAICE_salinity are 4 to 10 g/kg.
438      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
439      * added SEAICE_availHeatFrac, which specifies fraction of surface level
440        heat content used to melt or grow ice
441      * commented out cap of HICE: it helps keep ice thinner
442      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
443      * applied OBCS T/S mask to HEFFM sea ice mask
444    
445    checkpoint59d
446    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
447     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
448     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
449    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
450     and change default value of parameter "GM_Small_Number";
451     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
452       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
453       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
454    o pkg/ecco: cost function when applying pkg/smooth to controls
455    o pkg/ctrl: add forcingPrecond run time parameter
456    o pkg/seaice:
457     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
458     - fix bug in metric terms of u-equation in LSR solver (implicit part),
459       changes verification/lab_sea
460     - rearrange implicit part of u-equation in LSR solver to make it easier to
461       read, understand, and debug. This causes changes at the truncation level.
462     - fix (serious) bug in the boundary conditions (sign error in the implicit
463       part) of the LSR solver. Changes all LSR results.
464     - fixed problem with HSNOW initialization to avoid thick snow when AREA
465       is initilized with small values - does not change lab_sea results.
466     - added HsnowFile initialization capability
467    o pkg/smooth: addition to model/src and pkg/ctrl so allow
468     initialization of pkg/smooth and application to control vector
469    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
470    o dependencies: pkg/profiles requires pkg/cal
471    o pkg/profiles:
472     - added option ALLOW_PROFILES_GENERICGRID
473         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
474         that interpolation information (grid points and coefficients) is provided
475         within the netcdf input files.
476         -> sample matlab scripts can be found in MITgcm_contrib/gael
477         that allow you to prepare netcdf input files.
478     - also modified: cleaner include statements, cleaner error print statements,
479       cleaner stops when error, and more tests of the netcdf input files consistency.
480    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
481    o pkg/seaice:
482     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
483       requires a new routine: seaice_diagnostics_fill.F
484     - make sure that seaice does not move if not forced (pressure replacement
485       method, Hibler and Ip, 1995), changes results
486     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
487     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
488       It is turned off by default (=-1.), because it changes the results.
489     - make it possible to read AREA from a file, too.
490    
491    checkpoint59c
492    o add S/R and diagnostics for oceanic mixed-layer depth
493    o move GMRedi call after all vertical mixing schemes (including KPP)
494    o pkg/thsice:
495     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
496      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
497    o pkg/obcs:
498     - bug fix for balance code
499    o pkg/seaice:
500      - allow values of SEAICE_elasticParm > 1
501      - add new parameter SEAICE_evpTauRelax as an alternative
502        to SEAICE_elasticParm
503      - make lsr boundary conditions free slip (by default), changes result
504      - add code for no slip boundary conditions for lsr
505      - set minimum of zeta to zero (and not 4e8) (changes results)
506      - add a cap on AREA after advecting AREA if seaice_growth is not called
507    o change calculation of Visbeck K:
508      - no longer depend on tapering scheme; instead, compute slope (limited
509        by GM_maxSlope). this is equivalent to what was comuted before with
510        clipping or linear tappering.
511      - fix vertical averaging (wrong by 1/2 level)
512      - leave the old version (but will not be maintained) within
513        #ifdef OLD_VISBECK_CALC / #endif
514      - update output of exp. ideal_2D_oce
515    o change error catch in calc_r_star to improve vectorization
516    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
517      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
518    o adjoint:
519      Re-organized adjoint checkpointing according to Matt Mazloff
520      (but with modifs/completions/cleanups)
521      Storing is now bundled into large arrays to optimized I/O
522      (and second step in cleanup of the_main_loop)
523    
524    checkpoint59b
525    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
526      - export/import (between ocean & coupler) fields needed for ocean DIC.
527    o pkg/seaice:
528      - get rid of three more exchanges seaice_calc_viscosities (required
529        different loop boundaries in seaice_lsr and seaice_ocean_stress)
530      - bug fix in seaice_ocean_stress (update of lab_sea required)
531      - reduce loop boundaries to necessary minimum also in seaice_evp
532      - go back to the old way of computing deltaC/Z as the adjoint likes that
533        better
534    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
535      passive tracer to an Age Tracer) + update output.txt
536    o pkg/exf:
537      - implement A-grid / C-grid selection for wind-stress input files.
538      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
539      for now, in exf_bulk_largeyeager04.F only :
540      - change implementation for case where windspeed + 2. components wind-stress
541        are read-in. AND use rhoConstFresh to convert evap.
542    o pkg/seaice:
543      - use correct EXCH_UV for wind-forcing (on A-grid).
544      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
545        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
546    o pkg/exf:
547      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
548      EXF_INTERPOLATION:
549      - merge global_with_exf/code version of exf_interp_read.F
550        to the main code ;
551      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
552        reading the file ; Important: This options needs to be defined to recover
553        previous code.
554        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
555      - no longer loose real*8 precision along the way when using exf_iprec=64.
556    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
557      - change discretisation of evp-solver in order to avoid another exchange
558        (changes lab_sea) and clean up a little
559      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
560        help the adjoint (this also changes the results slightly)
561      - add a few "_d 0" where they had been missing in seaice_evp.F
562      - cleaning up: remove unused seaice_calc_rhs.F
563    o pkg/exf: some cleaning-up:
564      - change various "constants" into runtime parameters
565      - cleaned-up Large&Yeager04 routine which should eventually
566        replace exf_bulkformulae.F (changed names of S/R and CPP)
567        and merged various ALLOW_ATM_WIND options
568     only used with thsice pkg (in thsice_get_exf.F):
569      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
570        which are used when useStabilityFct_overIce=TRUE (= the default)
571      - change default values of ice & snow emissivity and scale downward LW
572        by ice & snow emissivity.
573    o pkg/thsice:
574     fix few little problems, in thsice_calc_thickn.F:
575      - growth vertically (and not laterally) if iceFrac == iceMaskMax
576      - melt only laterally if hIce < hThinIce (as the comments say)
577      and in thsice_extend.F:
578      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
579      - start to form ice as soon as the minimum ice-volume is reachable.
580     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
581      and cpl_aim+ocn
582    o pkg/kpp
583     - move computation of surface related input fields to KPP into a new
584       subroutine kpp_forcing_surf.F
585     - remove wrong (within bi,bj loops) EXCH calls.
586     - little cleaning (add argument myThid in last position, cvs header ...)
587     - for now, fix conservation problem by exchanging KPPviscAz (may not
588       be the best fix)
589    o pkg/seaice
590     - check for inconsistent evp parameter/cpp-flag combination
591     - remove leftover errIO flat for obsolete name list error handling
592    o OpenAD
593     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
594    
595    checkpoint59a
596    o pkg/seaice: some parameter clarifications and a little bit of clean up
597    o pkg/thsice: rename run-time parameters:
598       himin       -> hIceMin
599       himin0      -> hThinIce
600       hihig       -> hThickIce
601       i0          -> i0swFrac
602       transCoef   -> bMeltCoef
603       frac_energy -> fracMelting
604      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
605       with default values (for now) that do not change the results.
606      remove old version of thsice vars advection in pkg/seaice.
607    o in FFIELDS.h:
608      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
609      - make pLoad & sIceLoad always available (but still only used if
610         ATMOSPHERIC_LOADING is #define).
611    o pkg/kpp: replaced _KPP_RL with _RL
612    o bug fixes for vertical diffusivity computations when both KPP and
613        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
614        are no longer updating the vertical diffusivity array
615        (passed as argument) but are (re-) setting those arrays.
616    o pkg/seaice: fix bug in evp solver, while doing that
617      - change (improve?) discretization of stress computations for both
618        cgrid-lsr and evp solver
619      - add a new routine to compute strain rates
620      - the above changes lab_sea results
621      - add no slip conditions for evp solver (off by default), lsr-version
622        may follow
623      - fix exchange for shear at Z-points (does not change lab_sea)
624      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
625        (to force the user to pick a time step since there is not "safe" way
626        of choosing it)
627      - add principal stress diagnostics
628      - rearrange fields for evp a little to avoid having to call a: too many
629        exchanges and b: exchanges for stress trensor components which we do
630        not have.
631      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
632        of evp, complete rewrite for lsr case (latter is does not yet work
633        in all cases)
634    o pkg/kpp: add code to have mixing in shelf ice caverns
635      - add myThid to all kpp routines (long overdue)
636    
637    checkpoint59
638    o pkg/exf:
639      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
640        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
641      - move exf header files from lower_case.h to UPPER_CASE.h ;
642        add missing cvs Header & Name
643      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
644      - add namelist param. selectStressGridPosition, exf_monFreq
645      - retire many _CLIM routines, and remove data.exf_clim
646        + params moved to data.exf
647        + climsst, climsss now handled by exf_set_gen, i.e.
648          climss?period=0 refers to constant field,
649          climss?period=-12 to monthly forcing
650      - split up namelists in data.exf
651    o pkg/seaice:
652      - remove seaice_exch and seaice_exch_uv
653      - remove superfluous exchange of theta
654      - add myThid to seaice_budget_ocean/ice
655      - add new interface for atmospheric wind forcing (C-grid only)
656        + new routine
657        + two new field (taux, tauy for stress over ice)
658        + removed one global field (DAIRN) for C-grid case only
659    o pkg/thsise
660      - 2nd set of modifs for thsice adjoint in conjunction with exf
661    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
662    
663    checkpoint58y_post
664    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
665      vertical diffusivity, similar to that in MOM4; turned on using
666      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
667      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
668    o Added capability for 3D specification of background vertical diffusion
669      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
670      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
671      "data" file that contains the 3D vertical diffusivity coefficients.
672    o ice dynamics (pkg/seaice) with thsice thermodynamics:
673      - add code within pkg thsice to advect & diffuse sea-ice fields
674      similar to (and will replace) what has been added in  seaice_advdiff.F,
675      but: - conserving Mass, Heat & Salt.
676           - better when using non-linear advection scheme (not yet fully tested)
677           - can also be used in atmospheric set-up (for now, only the diffusion).
678    
679    checkpoint58x_post
680    o IO option for global-file compact format:
681      - add options when generating topology (utils/exch2/matlab-topology-generator)
682      - add I/O capability (pkg/mdsio).
683      - adapt utils/matlab/rdmds.m to read this format.
684      for now long-line format not yet supported by pkg/mdsio (& exch2).
685    o shelfice: add a few diagnostics
686    
687    checkpoint58w_post
688    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
689      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
690      (and replace horiVertRatio in NH code).
691      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
692                         and tutorial_plume_on_slope (sensitive to truncation)
693    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
694      directly to drive seaice model (C-grid only)
695    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
696     - reintroduce computation of wind from stress,
697     - compute tau (in exf_bulkformulae.F) from windstress averaged to
698       mass points to avoid tau = 0
699     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
700    o rdmnc.m: make it work with "global" files created with gluemnc
701    o rdmnc.m : some improvements in dealing with singleton dimension
702      (tested on all testreport mnc output files).
703    o genmake2: disable pkg/profiles if netcdf test fails.
704    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
705    o move call to cal_readparms up to make calendar parameters/variable available
706      to all packages
707    
708    checkpoint58v_post
709    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
710      useDynP_inEos_Zc tested.
711    o pkg/exf: changes to properly interpolate/mask/scale initial fields
712    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
713      and portions thereof.  See read_cs.txt for description and examples.
714    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
715      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
716      following the great-circle arc between those 2 points.
717    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
718      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
719    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
720     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
721     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
722     - still needs work (not working with some options ; efficiency to improve)
723       and serious testing.
724     - use this scheme for temperature & salinity in 2 advection test exp.:
725       advect_xy & advect_xz, respectively.
726    
727    checkpoint58u_post
728    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
729    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
730    o testreport: add option "-skipdir" to skip some test.
731    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
732      momentum calculation.
733    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
734    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
735      remove checkpoint.F and the_correction_step.F (no longer used);
736      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
737    o add option (linFSConserveTr) to correct for tracer source/sink due to
738      Linear Free surface
739    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
740    o pkg/thsice: fix reading mnc-pickups
741    
742    checkpoint58t_post
743    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
744    o pkg/mdsio:
745     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
746       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
747       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
748     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
749     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
750       either MDS_READ_FIELD or MDS_WRITE_FIELD )
751     - new S/R (to replace MDSWRITEMETA), which allows to write more
752       informations (variable names, time ...) to meta files.
753     - modify rdmds.m to give back the meta file content.
754    o pkg/diagnostics: change vertical interpolation to be safer, and more
755       flexible (define p-levels to interpolate to in data.diagnostics);
756      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
757       diagnostic pointer.
758    o pkg/seaice: more cleaning up of seaice_growth, added many comments
759    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
760    o fix multi-category seaice:
761     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
762       SEAICE_MULTICATEGORY
763     - fix short wave heat flux
764    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
765       and allow to use EVP solver. Change forward lab_sea: test both EVP
766       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
767    o Initial check-in of lab_sea adjoint
768      (very similar to natl_box_adjoint/code_seaice)
769      * used C-grid and EVP solver
770      * used KPP, GM/Redi
771      * uses inAdExact=.TRUE.
772      * gradient checks fail for both ADM and TLM
773        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
774        f.d. gradients actually seem more problematic than ADM, TLM gradients;
775        issue is related to forward mismatch between g77 an ifort
776    o pkg/seaice: overhaul of thermodynamics
777     - growth.F and groatb.F are replaced by new routine seaice_growth.F
778     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
779     - move a few global fields out of SEAICE.h into seaice_growth.F and
780       make them 2D (FICE/QNETO/ ...)
781     - remove FO (it is the same as QNETO)
782     - introduce a few local fields to avoid modifying external fields such
783       as atemp, etc.
784    
785    checkpoint58s_post
786    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
787      changed exf_set_gen.F so that
788        genperiod=0 means input file is one time-constant field and
789        genperiod=-12 means input file contains 12 monthly means
790    o CG2D: use pre-computed solver main-diagonal (stored in common block);
791      this affects truncation error ; generate new output file for exp. which
792      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
793        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
794        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
795        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
796        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
797        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
798    o start implementation of deep-atmosphere and anelastic formulation
799    o verification: remove 2nd copy of input files and use script "prepare_run"
800      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
801    o mom_common/vecinv/fluxform: fix a few initialisation isssues
802    o profiles: fix for multithreaded case
803    
804    o diagnostics: rename few diags:
805      s/'PRESSURE'/'RCENTER '/g
806      s/'TICE    '/'oceFreez'/g
807      s/'TAUX    '/'oceTAUX '/g
808      s/'TAUY    '/'oceTAUY '/g
809      s/'SWFLUX  '/'oceQsw  '/g
810      s/DIFx/DFxE/g
811      s/DIFy/DFyE/g
812      and add few ocean-forcing diagnostics:
813      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
814    o modifications to pkg/seaice/growth.F and budget.F, which change results of
815      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
816      as actual snow thickness.  It now refers everywhere to effective snow
817      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
818    
819    checkpoint58r_post
820    o modifications to pkg/seaice/growth.F, which change results of
821      lab_sea experiment: fixes pertain to melting snow over open water, to
822      masking EVAP under sea ice, and to using the correct AREA variable for
823      computations of EVAP, PRECIP, HSNOW, and GHEFF
824    o add ability to read bathy, salt, and theta using MNC (off by def)
825    o add flooding algorithm and advection of HSNOW for pkg/seaice;
826      both are turned off by default and do no change any results
827    o seaice advection with pkg/thsice: a step toward the use of non-linear
828      advection scheme, but #ifdef or commented out for now (requires more EXCH).
829    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
830      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
831      in natl_box (affects results @ truncation level: update output.txt)
832    o multi-threading and IO:
833      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
834      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
835        (needed to work with SingleCpuIO): tested in all verif. exp.
836    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
837      affects the results (but none of the verification test uses this scheme).
838    o Adding some pkg/diagnostics capability to pkg/seaice
839      (will certainly be subject to changes)
840    o ctrl: adding new control variables:
841      lwflux, lwdown, evap, snowprecip, apressure, runoff
842    
843    checkpoint58q_post
844    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
845      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
846      high_res_cube configuration by 4% on Columbia.
847    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
848      add (in global_with_exf/code) a version of EXF_INTERP_READ without
849      dynamical allocation (seems to work in multi-threaded).
850    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
851      single CPU io) so that TAF does not have to see EESUPPORT.h
852    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
853    
854    checkpoint58p_post
855    o obcs: stop if obcs is used with useCDscheme = .true.
856    o shelfice:
857     - fix a sign error so that no slip at shelfice interface works
858     - remove stop for combination non-hydrostatic code and shelfice. That does
859       not mean, that the results are correct, but at least they are numerically
860       stable
861    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
862    o added adjoint exch routined for all exch*3d* routines
863      and updated flow directives
864    
865    checkpoint58o_post
866    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
867      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
868    o change controling S/R for writing pickup file (new S/R do_write_pickup)
869      and clean-up reading/writing of pickup files.
870    o fix local version of read/write pickup (NH part) in rotating_tank/code
871    o simplify EXCH interface:
872     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
873     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
874    o added the regrid package
875    o shelfice:
876     - add a simple boundary layer scheme to reduce noise
877     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
878    
879    checkpoint58n_post
880    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
881       local variable (not in common block).
882    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
883      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
884      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
885        to work with SingleCpuIO.
886    o add "_d 0" to real constant of pkg/cfc subroutines ;
887       update exp. cfc_exemple & tutorial_cfc_offline output files.
888    o multi-threading and IO:
889      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
890        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
891      - barrier before and after reading.
892      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
893      - avoid using MDS_WRITELOCAL for LAND pkg output.
894      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
895        common-block variables ; Allows multi-threading with master-thread IO.
896    o change default MAX_NO_THREADS from 32 to 4 ;
897      and stop cleanly when MAX_NO_THREADS is too small.
898    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
899    
900    checkpoint58m_post
901    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
902       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
903    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
904       keep global_ocean.90x40x15 (for AD testing) with former secondary test
905       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
906    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
907        add MITgcm_tutorials (= code + all the tutorials)
908    o ecco, option to compute cost for total ssh (mean+anom)
909    o consistent with addition of ptracer and ssh in pkg/profiles
910    o profiles: adding ptracer and ssh
911    o testreport: change multi-test output-file name
912      (from output.txt.{name} to output.{name}.txt)
913    o profiles: now ok for mutli-tiles case
914    o seaice: add 4 parameters for different advection schemes for area,
915      (effective) seaice thickness, enthalphy, and snow height. Their default
916      is the standard parameter SEAICEadvScheme
917    o calc_gw:
918     - add cosFacU in zonal viscous flux (harmonic.visc.).
919     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
920       of tutorial_plume_on_slope.
921    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
922    o calc_gw: true flux-form, account for horizontal grid spacing.
923      update rotating_tank results, but not plume_on_slope (affected at
924      truncation level, 11 digits).
925    
926    checkpoint58l_post
927    o calc_gw:
928     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
929     - remove side-drag for now (need to fix it); update plume_on_slope results.
930     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
931    o commit code to make SST/SSS weights spatially variable
932      (based on either variable in-situ or variable initial T/S weights)
933    o pkg/ecco:
934      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
935        now based on horizontally varying weights wthetaLev, wsaltLev
936      * cost_averagesflags now returns year indices in addition to day, month
937      * sflux balance is performed on annual basis
938        (sflxumm, sfluxmm2, bal_sfluxmm)
939      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
940        including separate counting and multipliers
941    o pkg/rbcs
942      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
943    
944    checkpoint58k_post
945    o testreport:
946     - always build in dir. "build" (if not there, mkdir build instead of building
947       & running in input)
948     - run in dir run (if it exists), in build otherwise.
949     - call prepare_run (if input/prepare_run exists)
950     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
951    o pkg/exf modifications to interpolation and rotation routines for more
952       reasonable treatment of North Pole singularity: for tracers North Pole
953       value is set to northernmost zonal-mean value, for zonal velocity it is
954       set to zero, and for meridional velocity it is set to northernmost value.
955    o pkg/exf/exf_check_range.F
956     - add tile index to diagnostics and move stop statement to the very
957       end of the routine.
958    o pkg/diagnostics: (diagnostics_main_init.F)
959      define title of isomorphic variables according to the current config.
960    o pkg/thsice with pkg/seaice dynamics:
961    - fix domain of computation (interior only, required for exf) and do exchanges
962    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
963    o towards a standard way of dealing with multi-threading in MONITOR
964      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
965    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
966       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
967    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
968    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
969    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
970       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
971    o tracer advection:
972     - clean-up and simplify calc_common_factors.F
973     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
974       advection subroutine (but still not used within DST advection S/R)
975    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
976    
977    checkpoint58j_post
978    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
979      from file (collects calls previously in FORWARD_STEP)
980    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
981    o adjoint store dir. adjusted accordingly
982    o genmake2
983      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
984    
985    checkpoint58i_post
986    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
987      on wind stress (SEAICEstressFactor defaults to 1.)
988    o Total number of Timers is finite (<=40): comment out 2 non-essential one
989      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
990    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
991      on CS-grid: no longer loosing mass.
992    o exf & curvilinear-grid: no longer modify longitude xC & xG.
993    o pkg/ggl90: fix sloppy output and fix a bug
994    o pkg/seaice: added SEAICEuseEVPpickup parameter
995      - Set to false in order to start EVP solver with
996        non-EVP pickup files when using SEAICEuseEVP
997      - fix sign error in diffusion in seaice_calc_rhs
998    
999    checkpoint58h_post
1000    * Modifications for bottom topography control
1001      o replace hFacC by _hFacC at various places
1002      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1003      o add non-self-adjoint cg2d_nsa
1004      o update autodiff support routines
1005      o re-initialise hfac after ctrl_depth_ini
1006      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1007    * Adding verification for 5x5 box (4-layer) bottom topography control
1008    
1009    checkpoint58g_post
1010    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1011       used for mean seasonal cycle, mean diurnal cycle); add an example
1012       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1013    o pkg/ggl90:
1014      - add parameter (minimum surface kinetic energy)
1015      - fix bug (avoiding division by zero)
1016    o couple pkg/thsice to pkg/seaice:
1017      - modify advection in seaice to accomodate new scalar fields to be advected
1018      - only muliDimAdection scheme work with seaice/thsice
1019      - mapping of thsice-variables to seaice-variables, back and forth
1020      - does not break the verification experiments, but does not give the
1021        desired results either
1022    o pkg/seaice
1023      - make (default) second order advection a bit less confusing?
1024    
1025    checkpoint58f_post
1026    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1027      to pkg/seaice):
1028      - new routines thsice_map_exf and thsice_get_exf provide the interface
1029      - add an additional formal parameter to thsice_solve4temp
1030    o pkg/exf:
1031      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1032      - correct Stefan-Boltzmann constant
1033      - new parameter for longwave surface emittance
1034      - separate some stuff from exf_bulkformulae into new routines  
1035        exf_radiation, exf_wind
1036      - add new parameters and constants: longwave emissivity for ocean, ice
1037        and snow, evaporation parameters over ice
1038      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1039        either wind from stress or stress from wind
1040    o pkg/thSIce:
1041    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1042    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1043       and THSICE_CALC_THICKN
1044    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1045    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1046      to make debugging easier.
1047    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1048    o pkg/bulk_force:
1049      - clean-up comments and parameters ;
1050      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1051    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1052      generate new output for test-experiment: aim.5l_cs.thSI
1053    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1054      testreport accordingly
1055    
1056    checkpoint58e_post
1057    o SEAICE_CGRID adjoint done
1058    o R_STAR adjoint implemented.
1059      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1060      * need to sort out init. of h0facc, etc.
1061    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1062      to be able to use it in pure forward.
1063    
1064    checkpoint58d_post
1065    o upgrade simple test-experiment to tutorial example:
1066     step.1: duplicate the experiment and (step.2) will remove the old copy.
1067      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1068      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1069      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1070      tutorial_global_oce_biogeo    <- copy of dic_example
1071      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1072      tutorial_plume_on_slope       <- copy of plume_on_slope
1073      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1074      tutorial_global_oce_optim     <- empty for now (David ?)
1075      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1076     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1077    o correct a sign problem in cost_scat.F
1078    o obcs and ptracers: fix boundary conditions for advections schemes
1079      with larger stencil
1080    o thsice adjoint: start
1081    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1082      completeness
1083    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1084      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1085    o ptracers adjoint:
1086      * avoid extensive recomputatations
1087      * fix missing re-init. of gptr (missed by TAF)
1088    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
1089      me to turn off the excessive output to STDOUT that this package produces
1090    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1091      and add those terms in Vector-Invariant formulation.
1092    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1093      if the control period (xx_hfluxperiod etc) is 0
1094    o in profiles pkg, clean routines and fix details
1095    o in ecco pkg, reading ssh data:
1096      fix problem in case the model does not start at iter0=0
1097    o fix mnc-pickup/restart for ptracers
1098    o new package prifiles:
1099      code to compute profile-based cost by Gael Forget
1100      (modifs in ecco, ctrl, autodiff)
1101    o Benign bug fix in initialization (spotted by M. Mazloff) of
1102      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1103    
1104    checkpoint58c_post
1105    o adjoint: finish NLFS adjoint and provide reference output in
1106      verification/global_ocean.90x40x15/results_ad_nlfs
1107    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1108      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1109      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1110      with SEAICE_CGRID defined.
1111    o move calendarDumps from "data" to "data.cal" and clean-up the code
1112      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1113    o add useEXF & useCAL flags (for now, set in hard-coded way)
1114    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1115      (were missing in NH mode, and wrong in quasihydrostatic mode).
1116      waiting for Chris updated version of calc_gw to add those CALLs.
1117    o fix bug in quasihydrostatic S/R ;
1118      add a test for this option: global_ocean.90x40x15.qshyd
1119    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1120      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1121    o add on/off flag useOffLine for package OFFLINE
1122    o seaice:
1123      - modify advection so that it works also on the C-grid
1124      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1125        problem in multi-tile runs with C-grid
1126      - add flags for clipping ice velocities and/or masking solver forcing
1127      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1128        C-grid solver
1129      - added a few comments to seaice_diffusion.F
1130      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1131        are now exclusive)
1132      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1133        required re-ordering the code a little:
1134       + make DAIRN global variable (defined in SEAICE)
1135       + move computation of the viscosities eta and zeta into a new separate
1136         routine (because I need to recompute them in seaice_ocean_stress.F)
1137    
1138    checkpoint58b_post
1139    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1140      update output.txt of exp. aim.5l_cs.thSI
1141    o various mnc cleanups and improvements:
1142      + shrink lookup tables by factor of ~4
1143      + better error reporting when running out of lookup space
1144      + able to handle longer path/file names (up to 500 chars)
1145    o adjoint:
1146      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1147      - TBD: "hidden" mom_vecinv recomp. in dynamics
1148    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1149     (allow to differentiate between forcing components using new integer flags:
1150      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1151     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1152    o ecco
1153      - enable trend removal from SSH anomaly obs.
1154    o adjoint
1155      - a fix for PmEpR when #undef EXACT_CONSERV
1156      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1157      - try to fix "hidden" recomp. in forward_step for NLFS
1158        (NLFS seems broken sometimes after I checked it in)
1159    o seaice:
1160     - add c-grid version of the dynamic solver:
1161       + three new routines that are the c-grid substitute lsr, dynsolver
1162         and ostres
1163       + put a few fields that were local to dynsolver into global common
1164         blocks, so that I can move the computation of stresses etc into
1165         seaice_lsr (saves coding but may break the adjoint).
1166     - replace more hardwired parameters by runtime parameters
1167     - add ice masks that mask the rhs of the implicit solvers where there
1168       is no ice (commented out in seaice_dynsolver, because i am not sure
1169       if this works properly), eventually this should replace the clipping
1170       of ice velocities in seaice_dynsolver to +/-40cm/s.
1171    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1172      include it only where its needed
1173    o move balancing of fluxes before the call of external_forcing_surf
1174    o seaice:
1175      - correct units of turning angles (now they are really in degrees)
1176      - move computation of GWATX/Y out of main routine into dynsolver
1177      - initialize GWATX/Y in seaice_init
1178    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1179      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1180    o seaice: add runtime flags for turning angles (default to zero)
1181    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1182      and trend from exf forcing and ctrl control adjustments
1183    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1184      (since checkpoint57x_post)
1185    o change the default rotation period to 86164.s = the Earth rotation
1186    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1187      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1188    o seaice advection: add code for choosing between the default (2nd order
1189      central differences) and multiDim advection schemes provided by
1190      pkg/generic_advdiff
1191    o seaice:
1192      - removed all references to SEAICE_GRID.h fields from
1193        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1194        (cubed-sphere configuration will change a little)
1195      - grid computations in seaice_init are obsolete now.
1196      - cleaned up code a little so that is easier to read (hopefully).
1197      - added new (better?) discretizations of default advection and diffusion
1198        (turn on with SEAICEuseFluxForm)
1199      - replace 1 in 3d global fields by kSurface in growth.F
1200      
1201    checkpoint58a_post
1202    o seaice:
1203      - bug fix in advect.F
1204    o shelfice:
1205      - separate shelfice load anomaly from pload (breaks with time
1206        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1207        Its default is 0., but it may be computed more cleverly from (unknown)
1208        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1209        done offline. A good approximation of the pressure load anomaly is
1210        necessary to avoid large initial adjustment processes underneath
1211        deep-reaching shelfice.
1212      - small fix in ISOMIP shelfice_thermodynamics
1213      - add more sophisticated thermodynamics of Hellmer (1989), this is
1214        now the default
1215      - give a few constants more intuitive names
1216    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1217      if bulk formulae are used in long integration (especially EmPmR). Turn
1218      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1219      if balancePrintMean, the imbalance that is substracted is printed to
1220      STDOUT.
1221    o fix bug (typo) in obcs_apply_eta.F
1222    o add a new package shelfice which enables us to model the circulation
1223      underneath shelf-ice with draughts of hundreds of meters.
1224     - works
1225     - to do: + include improved thermodynamics
1226              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1227                instead of new field kTopC
1228              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1229                instead of new field R_shelfIce and new code in ini_depth.F
1230                and ini_mask_etc.F?
1231              + adjust vertical mixing schemes?
1232    o seaice pkg:
1233     - add a cpp-flag to include a simple formula for a salinity dependent
1234       freezing point of sea water at the surface
1235     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1236       meridional stresses are now different (and hopefully correct)
1237    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1238       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1239       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1240    o pkg/diagnostics: add options and parameters for regional-statistics
1241       diagnostics ; define regions by reading a region-mask from a file
1242       (might add other options later)
1243    o pkg/bulk_force:
1244     - add option and parameters to use AIM surface-flux formulae.
1245     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1246       others forcing fields (defined in PARM05, parameter file "data") are loaded
1247       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1248     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1249     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1250     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1251       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1252     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1253    
1254    checkpoint58
1255    o add "--embed-source" option to genmake2 which, when the supporting
1256      tools can be compiled (as determined by genmake2) will turn on the
1257      embed_files package which then embeds the entire MITgcm source code
1258      (*.[fFhc] + Makefile) used for the build within the executable
1259      - requested by CNH but off by default
1260      - adds a paltry <9MB to the mitgcmuv executable in most cases
1261      - only writes the output when useEMBEDSRC in eedata is true
1262    o clean up 3-dim. relaxation codes:
1263      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1264      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1265      * Thanks to Tom Haine for testing!
1266    
1267    checkpoint57z_post
1268    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1269      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1270    o fix the pickup behavior for obcs in combination with ptracers
1271    o fix a bug in ptracers_external_fields_load
1272    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1273      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1274    o transfered surface NH pressure to eta field (if exactConserv).
1275    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1276         and update lab_sea output.txt file.
1277    o completing 3-dim. relaxation code: additional term
1278         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1279      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1280      * At compile time, in "EXF_OPTIONS.h" set
1281          #define  ALLOW_CLIMTEMP_RELAXATION
1282          #define  ALLOW_CLIMSALT_RELAXATION
1283      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1284          tauThetaClimRelax3Dim = 15552000.0,
1285          tauSaltClimRelax3Dim  = 15552000.0,
1286      * 3 cases:
1287          1) Use a constant-in-time 3-dim. field
1288          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1289          3) Real-time relax. to time-evolving prescribed field
1290    o Adding Laplacian-type smoothness constraint on
1291      initial and boundary (forcing) controls (ic, bc)
1292      * enable at compile-time via
1293        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1294      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1295      * Absolute scale somewhat unclear so far
1296      * no area weighting was included since no other cost term does so far
1297    
1298    checkpoint57y_post
1299    First step for a NLFS adjoint
1300    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1301    o new init. routines for calc_r_star, calc_surf_dr
1302    o still need to deal with ini_masks_etc
1303    o testreport seemed happy
1304    checkpoint57y_pre
1305    
1306    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1307    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1308    o add new offset feature to offline pkg (plus minor cleanup)
1309    o cfc fixes for final year of integration
1310    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1311      be in GCHEM_OPTIONS).
1312    
1313    checkpoint57x_post
1314    o fix testreport Pb in multiple test experiment.
1315    o cleanup our namelist syntax in verification:
1316      - make it more F95 standards compliant (some work still needed)
1317      - allows the vast majority of our tests to work with gfortran
1318    o Non-Hydrostatic:
1319     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1320     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1321    o Allow to apply AB on T,S rather than on AB(gT,gS):
1322     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1323     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1324       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1325     - need a "clever" read_pickup to restart from the other AB formulation
1326    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1327    o remove some unused variables (reduces number of compiler warnings)
1328    o adjoint
1329      * Disable useVariableViscosity for adjoint for time being
1330        (there are a number of extensive recomputations)
1331      * Initialize certain variables needed for adjoint
1332    
1333    checkpoint57w_post
1334    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1335                 fix the singleCpuIO RS version of MDSWRITEFIELD
1336       and add a WARNING if using globalFiles=T with multi-processors.
1337    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1338      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1339    o tracer advection scheme:
1340      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1341       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1342       was not very convenient).
1343      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1344       (further tests needed for the implicit DST & Flux-Limiter schemes).
1345    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1346      and sRef for convenience, handy, when you want to initialize
1347      ptracers in a large domain with a constant non-zero value. Also,
1348      untangle ptracers_init.F a little.
1349    
1350    checkpoint57v_post
1351    o change dome exp. to use variable viscosity in side-drag terms.
1352    o remove all the files from the cfc_offline test since they are now
1353      incorporated into tutorial_cfc_offline which has been producing
1354      identical results for a few days of testing
1355    o add new parameter: sideDragFactor to enable half-slip-side BC
1356      and change side-drag S/R to use viscosity from mom_calc_visc
1357      (can switch back by setting sideDragFactor=0.); affects results at
1358      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1359       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1360    o vorticity & strain are now computed without masking, to account for
1361      no-slip-side BC in variable viscosity calculation ; mask is applied
1362      anyway later on, before computing advection/coriolis terms.
1363    o modify exp4 to test new obcs support for reading from external files
1364      and for passive tracers
1365    o fix behavior of ptracers_monitor when monitor output is written to a
1366      netcdf-file; still not independent of monitor.F (writes in the same
1367      file).
1368    o change default value of tRef (put a uniform, meaningful value for ocean
1369      & atmos) and initialize sRef (was missing, as Martin mentioned).
1370    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1371      to be proportional to enstrophy dissipation length.  Thus,
1372       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1373      This is now consistent with Smagorinsky and with the manual.
1374    
1375    checkpoint57u_post
1376    o OBCS and PTRACERS: add open boundary support for passive tracers
1377      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1378        OB-values from file; this is not different from the way theta and salinity
1379        are treated
1380      - however, Orlanski-radiation conditions are not supported, and the model
1381        will stop if you use pTracers and Orlanski at the same time.
1382      - beefed up the rountine obcs_external_fields_load: now only those open
1383        boundary values are overwritten with values from files for which there
1384        are really files, otherwise the OB-fields remain untouched. This makes
1385        it possible to use different OBs at different ends of the domain (as
1386        with EXF)
1387    o reduce number of exch calls in shap_filt (s2).
1388    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1389      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1390    
1391    checkpoint57t_post
1392    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1393    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1394      same truncation, independent of the face number: affects affects several
1395      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1396    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1397      note that biharmonic viscosity + no-slip was not tested in any experiment.
1398    o fix bug in non-linear free-surf side-drag ; generate new output for
1399      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1400    o make mnc honor the writeBinaryPrec flag for most kinds of output
1401    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1402    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1403      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1404    o add brackets in multi-terms sum to get same truncation, independent of
1405      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1406      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1407    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1408      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1409      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1410      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1411      Suggested values of viscosity parameters found in mom_calc_visc.
1412      Many new viscosity diagnostics available.
1413    
1414    checkpoint57s_post
1415    o Add clearing-house for viscosity calculations, mom_calc_visc and
1416      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1417      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1418      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1419      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1420      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1421      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1422      ViscAhStrain and viscAhTension are now retired.
1423    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1424    o In response to JMC's bug report, genmake2 now ignores any soft-links
1425      that it finds in the *current* directory when searching for files.
1426      Soft-links found in any other source directories will still work as
1427      they did before.
1428    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1429      a C routine to unlimit the stack size
1430    o mnc-ify pkg/aim snapshot vars
1431    o mnc-ify pkg/land as requested by Daniel
1432    o various changes to mnc including:
1433      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1434      - output can now be grouped so that all files within a group
1435          change the ITER portion of their names in lock-step together
1436      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1437          and works with both EXCH1 and EXCH2 (but needs more testing)
1438      - writing works for all verification test cases w/ g77 on Linux
1439    
1440    checkpoint57r_post
1441    o make MNC variable initialization happen earlier
1442    o add diagnostics for (almost) each term of the momentum Eq.
1443    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1444    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1445    o remove MINIMAL_TAVE_OUTPUT option ;
1446      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1447    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1448      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1449    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1450    o add time-dependent SST, SSS control
1451    o cost terms in ecco/ modularized (new cost_generic.F)
1452    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1453    o new infrastructure for seaice model vs. obs misfits in seaice/
1454      * driver from the_main_loop.F is seaice_cost_driver.F
1455      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1456      * gradient check in Exp. 6a of natl_box_adjoint/
1457    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1458      (see README file)
1459    
1460    checkpoint57q_post
1461    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1462    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1463      - bug was reported by Jean-Michel and Ian Fenty
1464    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1465      update exp. cpl_aim+ocn output.
1466    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1467      Needed for high-res. runs with large global files
1468      to be able to limit tapelev size
1469    o Changed some tests for adjoint:
1470      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1471      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1472      * global_ocean.90x40x15/ back to default 3-level checkpointing
1473    o Modifications to enable scripted COMMON to MODULE conversion
1474      * verification/OpenAD/code/ has necessary scripts and description;
1475      * converts, compiles and runs successfully;
1476    
1477    checkpoint57p_post
1478    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1479    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1480      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1481    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1482    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1483      (was already the case for dissipation with mom_vecinv,
1484       and also the case for grad.PhiHyd when staggered-timeStep)
1485      This will allow to put dissipation out-off the AB time-stepping.
1486     Unfortunately, affects truncation error. Update output of exp. that "fails"
1487      (cg2d matching number) and leave the others for later: front_relax(10),
1488      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1489      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1490    
1491    checkpoint57o_post
1492    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1493      (2) its ready to be documented during the 20050801 DocFest
1494    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1495      for ideal_2D_oce and lab_sea on linux_ia32_g77
1496    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1497      in global1x1_tot/code_seaice_adj to access indices 32, 33
1498      (worth another tag)
1499    
1500    checkpoint57n_post
1501    o adding precip control xx_precip 32
1502    o adding swflux control xx_swflux 33
1503    o Replacing 10 forcing penalty cost routines by 1 generic.
1504    o Implementing partitioning in time-mean and variable adjustment
1505      for atmos. state.
1506    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1507    o in natl_box_adjoint:
1508      * updated exp 1 to 10
1509        (but does not have time-mean vs. variable split results yet)
1510    o updated global1x1/*_seaice_adj/
1511      to incorporate latest changes
1512    o enable useSingleCpuIO for mdsio vector routines
1513      (applies in particular to tapelev I/O)
1514    o removed inefficient K-loop in all active_file*control*.F
1515    
1516    checkpoint57m_post
1517    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
1518      and advect_cs (use EXCH-2 and standard cs-32 grid files).
1519    o pkg/exch2: filling of face-corner halo regions is optional
1520      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
1521    
1522    checkpoint57l_post
1523     tag before updating tutorials (pre-release-2)
1524    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
1525       for output and interpolation of input fields onto model grid)
1526    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
1527       Affects results of exp. rotating_tank ; update output.txt.
1528    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
1529          and taking the square quantity and/or using a fraction-weight field.
1530    o fix aim_diagnostics_init.F mate numbers.
1531    o add mnc output capability to diagnostics/diagstat and update
1532      our cvsignore files for the ACSII output generated
1533    
1534    checkpoint57k_post
1535    o lab_sea now uses diagnostics package and provides a suite of
1536      new EXF diagnostics output.
1537    
1538    checkpoint57j_post
1539    o exf
1540      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1541        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1542        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1543      * extended diagnostics output
1544        - now includes all EXF variables
1545        - hs, hl moved to common block
1546        - separate S/R for diagnostics, called after ctrl vector is added
1547        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1548        - EXFqnet contains true Qnet (i.e. includes qsw)
1549      * updated verif. lab_sea, global_with_exf
1550      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1551        to ensure that diagnostics sees a true EXFqnet
1552    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1553    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1554      several times with different frequencies.
1555    o mnc-ify the thsice package as requested by Daniel Enderton
1556      - the monitor--MNC output needs work
1557      - many attributes need to be added (most are currently blank)
1558    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1559      - many attributes need to be added (most are currently blank)
1560    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
1561    o add Sadourny like discretization to the 4th.O vorticity advection scheme
1562    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
1563      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
1564         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
1565    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
1566     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
1567    
1568    checkpoint57i_post
1569    o Diagnostics package was changed: diagnostic allocation is now deactivated
1570      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1571    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1572      add 1rst Order upwind vertical Shear.
1573    o add a quick fix for A/B checkpointing in OFFLINE mode
1574    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1575      end-run around the C/Fortran linking horror in eesup/src/timers.F
1576    o added pkg/runclock: allows user to terminate run based on wall clock
1577    o added non-hydrostatic scaling parameter: nh_am2
1578    o pkg/my82: futile attempt to make results compiler-independent by adding
1579      some "_d 0", etc. no effect.
1580    o for mnc output, fill the 'T' coordinate var with myTime and create a
1581      separate 'iter' variable for iteration count
1582    o pkg/diagnostics:
1583      add new capability: output of Global/Regional & per-level statistics ;
1584      tested against monitor output (including land & thSIce) on various exp.
1585    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1586    
1587    checkpoint57h_done
1588      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1589      data.diagnostics, data.gchem, data.ptracers) is done.
1590    
1591    o pkg/diagnostics: prepare for Global/Regional statistics.
1592      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1593    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1594      and rename it: DIFFERENT_MULTIPLE
1595    
1596    checkpoint57h_post
1597    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1598    o pkg/diagnostics: change output frequency, now in seconds (instead
1599      of Nb of iterations). This requires to change data.diagnostics.
1600    checkpoint57h_pre
1601    
1602    o in mnc, let the user create the output dir if both mnc_outdir_date
1603      and mnc_outdir_num are false
1604    o add fflags() to pkg/diagnostics which allows one to specify, on a
1605      per-file basis, the file precision [default behavior is unchanged]
1606    o added diagnostics to pkg/kpp, including computation of mixed layer
1607      depth based on a temperature/density criterion
1608    o updated verification/natl_box to test the new pkg/kpp diagnostics
1609    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1610    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1611    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1612      not mnc -- this mistake was found by JMC and is now corrected
1613    
1614    checkpoint57g_post
1615    o add Adams-Bashforth 3rd Order time stepping:
1616      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1617      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1618    checkpoint57g_pre
1619    
1620    o make lambda[Theta,Salt]ClimRelax spatially varying
1621      (default remains spatially uniform constant based on tau)
1622    o added new control variables
1623      * init. uVel, vVel, etanN
1624      * lambda[Theta,Salt]ClimRelax
1625    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1626      (suggested by G. Forget)
1627    
1628    checkpoint57f_post
1629    o add parameter "baseTime" = model base time = time at iteration zero
1630      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1631      account for baseTime shift
1632    o move Coriolis arrays from PARAMS.h to GRID.h
1633    checkpoint57f_pre
1634    
1635    o mnc-ifying the seaice package
1636    o introduced an alternative length scale calculation for use in the limiting
1637      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1638    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1639    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1640      as well as grad(vort3).  Made it compatible with both approximate form
1641      for the cubed sphere and full form of these gradients.  Added flag
1642      useFullLeith to select between approximate and full form.  
1643    o add "d0" in getcon.F to reduce differences between compilers/platforms
1644      update output.txt of exp. fizhi-gridalt-hs
1645    o change port_rand funtion to allow to set the seed.
1646    o fix obscure MNC bug involving conversion between reals and integers
1647      - it caused no problems with certain (eg. gcc, ifc) compilers but the
1648        new version is now more standards-compliant
1649    o adjoint-related modifications
1650      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
1651      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
1652      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
1653    
1654    checkpoint57e_post
1655    o Adding eddy stress controls a la Ferreira et al.
1656    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
1657    
1658    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
1659      update output.txt of exp. fizhi-gridalt-hs
1660    o add more "Z" dimensions and associated coordinate vars to MNC
1661    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
1662    o parameter calendarDumps: when set, approximate months (30-31 days) and years
1663      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
1664      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
1665      months and years.  Requires pkg/cal.
1666    o diagnostics: add pickup functionality
1667      - off by default for backwards compatibility
1668      - current version only uses MDSIO -- MNC will be added
1669    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
1670    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
1671    
1672    checkpoint57d_post
1673    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1674    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1675      output from the diagnostics package
1676    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1677    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1678      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1679    o add coordinate variables to the MNC output from the diagnostics package
1680    o change MNC-flags default value: true when useMNC=TRUE
1681    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1682      the ability (off by default) to read the grid information using MNC
1683    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1684    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1685    o do snap-shot diagnostics at the middle of the time-interval (instead of
1686      at the end).
1687    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1688      new test for AIM with thSIce + slab-ocean
1689    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1690    o move state variable diagnostics to the beginning of the time step ;
1691      (note: still needs some work specially for snap-shot diagnostics)
1692      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1693    
1694    checkpoint57c_post
1695    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1696    o generate new output.txt files on faulks with g77 & the new -ieee option
1697    checkpoint57c_pre
1698    
1699    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1700      update output.txt of exp. global_ocean.90x40x15
1701    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1702      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1703    o add saltFlux(+File) forcing capability with periodicExternalForcing
1704    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1705    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1706    o improvements for the MNC output from DIAGNOSTICS:
1707      - correct handling of the unlimitied dimension
1708      - all dims now have associated coordinate variables
1709      - variables located at U, V, and Corner ("Z") points are now written
1710        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1711        *all* data points are output
1712    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1713    o added pkg/seaice/seaice_monitor.F
1714    o mdsio_readfield.F can now read files visible only to master MPI process.
1715    o pkg/seaice: some test code for ice-modified ocean stress
1716    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1717      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1718      spurious negative numbers for precipitation and humidity.  Will cause
1719      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1720    o pkg/ctrl/
1721      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1722        May be enabled via doPackDiag
1723      *  introduce z-scaling of
1724         + gradient (doZscalePack) and
1725         + control (doZscaleUnpack)
1726    o pkg/mdsio/
1727      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1728      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1729    
1730    checkpoint57b_post
1731    o simplify options in diagnostics_fill arguments (remove weird combinations)
1732    o fix MNC coordinate variables so that they now contain per-face index
1733      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1734      general, EXCH2 grids are only aligned to a "local" coordinate system
1735    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1736    o Implement instantaneous output within pkg diagnostics:
1737      setting a negative frequency in data.diagnostics produces
1738     "snap-shot" output (as opposed to time-average if freq > 0)
1739    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1740      NOTE: change ptracer diagnostics name: use 2 characters to work with
1741            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1742    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1743      becomes the coordinate variable for the 'T' dimension
1744    o add CF-style coordinate variables to MNC
1745      - just a first cut:  numbers are meaningless on the cubesphere and
1746        missing along the T axis but otherwise it works!
1747    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
1748    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
1749    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
1750      this is based directly on what the model compute, so that the content of
1751      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
1752    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
1753    o clean up build options files for SunOS, in particular
1754      - remove -traditional from xmakedepend
1755      - change -xarch=v9 to -xarch=native for f77
1756      - restore use of make (not gmake)
1757      - add CC=gcc if using g77
1758    o changes per discussion of AM, JMC, & EH3 today:
1759      - move redundant "grid" variables out of "state" -- in preparation of
1760        creating proper CF-style coordinate variables and in recognition
1761        that any/all grid variables can be easily copied (eg. w/NCO) from
1762        the grid files into any of the other NetCDF files
1763      - *always* output grid variables with MDSIO (this will eventually be
1764        changed)
1765      - output MNC grid file if useMNC is true
1766    o every instance of _END_MASTER() has been found and replaced with
1767      _END_MASTER( myThid ) in order to satisfy certain picky Sun
1768      preprocessors
1769    o re-arrange diagnostics pkg initialisation:
1770     - allow each package to extend the available diagnostics list
1771     - add some checking and fix small problems (multi-threaded, ...)
1772     - new S/R diagnostics_fill (replace fill_diagnostics):
1773       look through the short list of active diag. (instead of the long list)
1774       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
1775    
1776    checkpoint57a_post
1777    o this set of changes restores TAMC compatibility
1778      tested for global_ocean.90x40x15 adjoint on trough
1779      (what a pain)
1780    
1781    checkpoint57a_pre
1782    o some modifs in tools/build_options for sunos
1783    o call ctrl_pack for ctrl at end for optimcycle=0
1784    
1785    checkpoint57
1786    o add horizontal bi-harmonic viscosity for vertical velocity
1787      - new parameter viscA4W (defaults to viscA4)
1788      - affects only non-hydrostatic code
1789      - to be done: no-slip lateral boundary conditions
1790    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1791    o implement Implicit Vertical advection for pTracers
1792    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1793      (implemented also for implicit vertical diffusion & advection)
1794    o OBCS: extend application of tracer open boundary conditions
1795      to a strip beyond the boundary of width Olx/Oly
1796    o add call monitor to TAF set of required calls (flow directives)
1797      and include in natl_box_adjoint
1798    o untangle a few ifdefs related to cost, ctrl, autodiff
1799      untangel a few ALLOW_ECCO_OPTIMIZATION
1800    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1801      (theta2, salt2 in ecco_cost_weights)
1802    
1803    checkpoint56c_post
1804    o OBCS as control variables
1805      - update ctrl_ad_diff.list, obcs_ad_diff.list
1806      - remove balance of obcs controls from default
1807      - fix index bug nobcs in ctrl_init
1808      - fix dummy fields filen in ctrl_pack
1809      - add dummy weights for obcs
1810    o lsopt: comment out fort.94 output
1811    o optim:
1812      - remove unnecessary header files
1813      - adjusted namelists
1814      - add xerbla.F to Makefile
1815    o exf:
1816      - multiple modifications of exf_check_range
1817      - unit change in exf_init_runoff from [m/year] to [m/s]
1818    o mdsio:
1819      - i/o-vector change debugLevel from debLevA to debLevB
1820    
1821    checkpoint56b_post
1822    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1823      is called from DO_THE_MODEL_IO
1824      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1825      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1826      - clean up PTRACERS_WRITE_TIMEAVE a little
1827    o add another verification experiment that tests both the cfc-pkg and
1828      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1829      reactive tendencies treated inline with regular timestepping
1830    o testreport previously did a lousy job of comparing small numbers, so
1831      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1832      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1833      testreport.
1834    o ptracers_monitor: bug fix for MPI
1835    
1836    checkpoint56a_post
1837    o GCHEM: finish reorganizating the package
1838      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1839        (introduces another 3D-array for each passive tracer, but only if
1840        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1841        gchemTendency is not needed because the timestep is done separately)
1842      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1843      - GCHEM is now---more or less cleanly---separate from PTRACERS
1844      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1845        so clear to me how that should be done in a general way.
1846    o CFC: improve formatting of output in CFC_ATMOS
1847    o PTRACERS:
1848      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1849        that ALL experiments with ptracers enable can be checked. This makes
1850        GCHEM_MONITOR obsolete.
1851      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1852        monitorFreq
1853      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1854    o add PTRACERS (PTR0[1-5]) to testreport output
1855    o exf_check_range:
1856      * default changed to .TRUE.
1857      * will check values for niter0 if debLevA, every timestep if debLevB
1858      * STOP in exf_check_range if 'out of range'
1859      * range chosen generous to allow for potential extema
1860      TBD: a version with stricter range
1861           permitted range would be runtime parameters
1862    o GMredi:
1863      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1864      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
1865      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
1866    o GCHEM:
1867      - move call to GCHEM_FORCING_SEP, so that it is now called before
1868        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
1869      - introduced a useGCHEM runtime flag and applied it everywhere.
1870      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1871        this flag is now only visible within GCHEM-pkg routines.
1872      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1873        be replaced by a 3D array that is computed before thermodynamics; for
1874        this, the tracer ID iTracer had to be included into the parameter list
1875        of ptracers_forcing
1876      - set up forward_step to call gchem_forcing, that will replace
1877        gchem_forcing_int in ptracers_forcing
1878      - cleaning up
1879    o small cleaning of exch2: remove files that are also in eesupp/src
1880    
1881    checkpoint56
1882    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
1883    o mnc: cleanup "full" files--fixes out-of-memory problem
1884    o ECCO-GODAE
1885      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
1886      * fully merged and updated from SIO code
1887        windstress sign change affects
1888        - exf_inscal_[u/v]stress
1889        - sign of xx_tau[u/v] adjustments
1890        - signs in cost_scat
1891      * ctrl_get_gen: avoid update of tau[u/v] for first few days
1892      * natl_box_adjoint updated and compressed
1893      * 2-level checkpoint switch added
1894        (tested in EXP. 1 of natl_box_adjoint)
1895      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
1896    o SVD
1897      * first complete, non-hacked version for SVD calculations
1898      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
1899        performed via direct access files admtlm_vector.it????
1900        (via ctrl_[un]pack)
1901      * optimcycle is used for ARPACK iteration counter
1902        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
1903      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
1904        and add linear transforms where necessary
1905      * controls are initial/final SST, SSS (can be extended; need to check
1906        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
1907    o mdsio: filename info to both stderr, stdout
1908    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
1909      from sign change
1910    
1911    checkpoint55j_post
1912    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
1913      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1914    o add consistent build directories and .cvsignore files to verification
1915    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
1916    o make all subroutines 30 or less characters in length for certain older
1917      compilers to work (a thorough search only turns up two routines in
1918      pkg/ptracers)
1919    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
1920      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1921    
1922    checkpoint55i_post
1923    o change arrays for total vertical diffusivity (2.D if explicit,
1924      3.D if implicit) ; each ptracer uses its own background value.
1925    o added mnc/NetCDF output capability to ocn_compon_interf
1926      - added bits to verification/cpl_aim+ocn so that it can run on
1927        ITRDA and other clusters without the mpirun "-wd" option
1928    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
1929      configuration
1930    o give MNC the ability to create additional files rather than
1931      exceeding a specified file size limit "MNC_MAX_FILESIZE"
1932      - the default is just less than 2GB which is a practical limit
1933        on many systems
1934    o Compute the non-local term using either KPP vertical diffusivity (=default)
1935       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
1936    
1937    checkpoint55h_post
1938    o add verification test "vermix"
1939    o remove all the *_ioinc flags and replace with the single global
1940      outputTypesInclusive flag
1941    o allow to set a vertical profile of vertical diffusivity for T & S
1942    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
1943    o useMNC moved from data.mnc to data.pkg
1944    
1945    checkpoint55g_post
1946    o Renaming carbon AD experiments to comply with testreport conventions
1947    o Updating adjoint of Held-Suarez hs94.1x64x5
1948    o Fixing directives for non-ECCO forward_step, after ECCO directives
1949      have been fixed to avoid recomp. of do_oceanic_phys
1950      Works well for global_ocean.90x40x15,
1951      but recomp. issue remains for carbon
1952    o Updating adjoint output for natl_box_adjoint after
1953      pkg/ecco has been modified (see taga c55d_post)
1954    
1955    checkpoint55f_post
1956    o rename to timeave_init_fixed
1957    
1958    checkpoint55e_post
1959    o some delicate re-shuffle of store directives to avoid one
1960      extra call of do_oceanic_physics
1961      affects ecco_the_main_loop.F, do_oceanic_physics.F
1962      checkpoint_lev1_directives.h
1963    o NB: this may break global_ocean adjoint temporarily,
1964      but it is clear how to fix it. Will do later, need this now.
1965    
1966    checkpoint55d_post
1967    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1968    o ecco_cost_weights is modified to 1x1 runs
1969    o modifs to allow observations to be read in as
1970      single file or yearly files
1971    o enable to read exf forcing fields as either
1972      single file or yearly files (flag useExfYearlyFields)
1973    checkpoint55d_pre
1974    
1975    o switch between 2-level and 3-level checkpointing
1976    o add ability of MNC to write local and "partial" (eg. 2D slices where
1977      the full 3D field is never actually stored) arrays to NetCDF files
1978      with the correct (that is, the complete multi-dimensional) set of
1979      array indicies
1980      - used in mom_vecinv() to write the diagFreq output
1981      - tested (demonstrated) in verification/aim.5l_cs
1982    o further mnc-ification
1983      - add verification/lab_sea to the list with mnc setups
1984      - fix undefined mnc v-names in cd_code
1985      - add kpp to mnc output (both snapshot and timeave)
1986    o non-hydrostatic code
1987      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1988        in calc_gw.F
1989      - defaults to viscAh
1990      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1991        friction or Leith) in non-hydrostatic mode, as long as there is
1992        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1993    o pkg/cost
1994      extend simple cost functions to treat time mean quantities
1995      (T,U,V) via cost_accumulate_state from cost_tile
1996    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1997        be 2 times larger than the minimum size the advection scheme requires.
1998        now get a perfect conservation of salt in advect_cs test-exp (updated)
1999    o GGL90 (Gaspar's TKE mixed layer)
2000      - add horizontal diffusion of TKE, requires exchanges in
2001        do_fields_blocking_exchanges, horizontal diffusivity is zero by
2002        default. In OPA there is no horizontal diffusion of TKE but the
2003        mixing coefficients are computed from a horizontal average of TKE of
2004        6 points or so. I think that diffusion has a little more physical
2005        justification.
2006      - clean up ggl90_calc in the hope of reducing memory usage (this hope
2007        was in vain)
2008      - mask tke-variable in ggl90_init
2009    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
2010    o fix biharmonic diffusion on CS-grid.
2011    o more obcs stuff
2012      - added obcs_external_fields_load as an alternative to the EXF-pkg option
2013        for reading boundary values. This routine is called from
2014        obcs_prescribe_read
2015      - updated obcs_check
2016      - changed sponge layer relaxation parameter units for days to seconds
2017      - turned off sponge layer by default
2018      - changed argument list of OBCS_CALC to myTime+deltaTclock
2019      - fixed about 35 bugs in obcs_external_fields_load
2020    
2021    checkpoint55c_post
2022    o obcs stuff
2023      - new runtime flags useOBCSprescribe, useOBCSbalance
2024      - re-arranged obcs_calc
2025      - moved exf_getobcs to obcs_prescibe_read
2026        obcs_prescibe_read is called after ORLANSKI stuff
2027        and independent of it (executable can contain all).
2028      - updated obcs_check
2029      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
2030        These may be necessary only if tangential velocities are
2031        prescribed at OB, not sure, needs testing.
2032    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
2033      which simplifies the calls and passes the ifc check-bounds test
2034    
2035    checkpoint55b_post
2036    o add a 2D scalar, Z location, exchange_2 routine.
2037    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
2038      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
2039      affects advect_cs results (for the wrong reason): update output.txt
2040    o use a more standard discretization for biharmonic viscosity ;
2041     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
2042      affects results of dome set-up: update output.txt
2043    o fix gad_advection.F (CubedSphere part), back to version 1.23
2044    o fix bug in mom_vi_del2uv.F (CubedSphere part).
2045    
2046    checkpoint55a_post
2047    o merged code to
2048      * prescribe/read time-dependent open boundaries
2049        (works in conjunction with exf, cal)
2050      * sponge layer code for open boundaries
2051      * each boundary N/S/E/W now has its own CPP option
2052        (healthy for the adjoint)
2053    
2054    checkpoint55
2055    o up-to-date adjoint of previous breaks
2056      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
2057      - global_ocean_ebm: adjoint still needs fix (TLM ok)
2058      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
2059      - carbon: * remove tr1-related adjoint verification
2060                * add ptracer as control variable
2061    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
2062      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
2063    
2064    checkpoint54f_post
2065    o in verification/carbin/ remove experiment related to
2066      ALLOW_PASSIVE_TRACER (array tr1 etc)
2067      code_ad/ input_ad/ results_ad
2068    
2069    o add two new packages
2070      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
2071        + subject to optimization (memory)
2072      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
2073        + subject to reordering (many GOTOs in the original code)
2074        + so far opps is called for every (i,j) point, and then operates in
2075          the vertical; one may want to reorder the scheme in order operate in
2076          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
2077          fields)
2078    o overhaul of IO so that we now have flags for MDSIO and/or MNC
2079      - all verification tests compile and run with linux_ia32_g77
2080      - defaults are compatible with current input files--nothing
2081        should change if you were not previously using MNC
2082      - MNC output has been added in numerous places (eg. timeave)
2083        but there are still a few writes not yet do-able with MNC
2084        (this is in progress)
2085      - flags now allow for either/or/both use of MDSIO and MNC and
2086        documentation will soon follow
2087      - numerous small formatting cleanups for ProTeX
2088    o add version info (via BUILD_INFO.h) to MNC and stdout
2089    
2090    checkpoint54e_post
2091    o add two new packages
2092      - pp81 (Packanowski and Philander, 1981), Richardson number and
2093        stratification dependent mixing
2094      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
2095      - these scheme operate in a similar manner as KPP (without ghat, of
2096        course), however there is only one diffusivity that is used for both
2097        temperature and salinity (and passive tracers)ç
2098    o add offline package
2099    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
2100      provided by Stephanie Dutkiewicz
2101    o genmake2: add ability to search for C compilers and cleanup test output
2102      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
2103    
2104    checkpoint54d_post
2105    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
2106    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
2107      leading to additional shift by 5 days each year of integration
2108       (i.e. leading to considerable offset over the years)
2109    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
2110    o start with no AB and no initial filtering (staggerTimeStep):
2111      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
2112    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
2113      (external loading & cpl import/export stay in forward_step.F)
2114    o update coupling interface to work with new staggerTimeStep
2115    o change MDSIO ptracers_pickup.
2116    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
2117    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
2118    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
2119    
2120    checkpoint54c_post
2121    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
2122      this affects (truncation error) output.txt of test-exp:
2123       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
2124    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
2125    o change Qnet to always be the net heat flux, (+upward).
2126      affects (truncation error) output of natl_box exp.: updated
2127    o define the max number of passive tracers in PTRACERS_SIZE.h
2128    o start to test mnc routinely in exp0
2129    o add sea-ice loading (sIceLoad) as a new forcing field.
2130    
2131    checkpoint54b_post
2132    o add testreport "-j JOBS" option for parallel builds (tested and pretty
2133       impressive on Altix and Opteron systems)
2134    o diagnostics can now write NetCDF files through the mnc package
2135    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
2136    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
2137    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
2138      affects (truncation error) output of lab_sea & natl_box exp.: updated
2139    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
2140    
2141    checkpoint54a_post
2142    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
2143    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
2144    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
2145    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
2146      + internal_wave (shift in writing cg2d_ini_res)
2147    checkpoint54a_pre
2148    
2149    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
2150      - modified verification/lab_sea and natl_box_adjoint accordingly
2151    
2152    checkpoint54
2153    checkpoint53g_post
2154    o prepare splitting of thermodynamics: store convect.counter in common block
2155    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
2156      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
2157    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
2158    o new parameter "nShapS": allow to treat differently S from T (nShapT)
2159    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
2160    o restore adjointability
2161    
2162    checkpoint53f_post
2163    o modifications that affect AIM experiment results (update output.txt):
2164      - no advection of S at top interface Nr (pkg/generic_advdiff)
2165      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
2166    o AIM pkg:
2167      - include stability function into surf.Flux derivative relative to Tsurf
2168      - calculate clear-sky radiation & surface temp. change (for diagnostics)
2169    
2170    checkpoint53e_post
2171    o merged cylindrical coord configuration
2172    o added rotating_tank experiment
2173    checkpoint53e_pre
2174    
2175    checkpoint53d_post
2176    o faulks upgraded: re-generate output.txt that have changed:
2177       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
2178    o Added Bryan and Lewis, 1979, vertical diffusivity profile
2179    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
2180    o added Sadourny discretization of Coriolis
2181      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
2182      - re-enabled use of omega3 (useAbsVorticity)
2183    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
2184      vector-invariant equations
2185      - note: does *NOT* yet use same variable visc. for no-slip BC's.
2186    o recoded the lateral boundary conditions for non-hydrostatic w, this time
2187      hopefully without new bugs
2188      - still to do: biharmonic friction for non-hydrostatic w
2189    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
2190    o regenerated output for global_ocean_ebm (using -ieee)
2191    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
2192      of mom_common/
2193      - simple re-arrangement of instructions within computing loop
2194    checkpoint53d_pre
2195    
2196    checkpoint53c_post
2197    o new version of coupler for AIM+thSIce and Ocean models
2198     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
2199     - land: change Evaporation of snow
2200     - aim with thSIce: fix bug in snow-precip.
2201    o changes to calc_gw.F
2202     - bug fix for w^2 term near the bottom boundary
2203     - (hopefully) improve the lateral slip boundary condtions for use with
2204        partial/looped cells
2205      - because the bug fix changes two verification experiments anyway (exp5
2206        and plume on slope), change the lateral boundary condition from half slip
2207        to the value of no_slip_sides
2208    o ebm package wasnt quite up to the parallel task. Fixed that.
2209    o Adjoint of EBM package + verification
2210      * TLM OK
2211      * ADM not sufficient accuracy yet (needs further testing)
2212    
2213    checkpoint53b_post
2214    o Commiting new energy balance model to repository
2215      * package is pkg/ebm
2216      * verif. is verification/global_ocean_ebm
2217      * references are in ebm_driver.F
2218    C      * X. Wang, P. Stone and J. Marotzke, 1999:
2219    C        Global thermohaline circulation. Part I:
2220    C        Sensitivity to atmospheric moisture transport.
2221    C        J. Climate 12(1), 71-82
2222    C      * X. Wang, P. Stone and J. Marotzke, 1999:
2223    C        Global thermohaline circulation. Part II:
2224    C        Sensitivity with interactive transport.
2225    C        J. Climate 12(1), 83-91
2226    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
2227    C        Destabilization of the thermohaline circulation
2228    C        by atmospheric eddy transports.
2229    C        J. Climate 7(12), 1870-1882
2230    o Will need long integration testing.
2231    checkpoint53b_pre
2232    
2233    o created pkg/mom_common in preparation for variable viscosity code
2234    o renamed and split ini_mnc_io
2235    o pkg/land: only liquid water can diffuse or run-off
2236    o AIM using land: soil wetness availability account for snow
2237    o added printMapIncludesZeros to EEPARMS namelist
2238    
2239    checkpoint53a_post
2240    o restore TAMC compatiility for exf_constants.h
2241      (no usage of _d in .h)
2242    o Additional storing in KPP in an attempt to fix
2243      TAMC problem with adjoint of KPP code.
2244      (no success...)
2245      Identical code works fine with TAF.
2246    o Fixed verification/natl_box_adjoint experiments.
2247      Initial conditions for Experiments 4 and 5 are now
2248      set to "SEAICE_initialHEFF=0", which is more reasonable,
2249      and hence gives results closer to that of Experiment 2.
2250      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
2251    
2252    checkpoint53
2253    o stable checkpoint with up to date adjoint
2254      TLM tests only run for 1st grdchk at the moment. Its unclear if
2255      this is a code problem or a problem with resetting code for g_
2256      variables that is being autogenerated wrong.
2257      Otherwise:
2258       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
2259       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
2260         are both still in chaos following their security messes.
2261    
2262    checkpoint52n_post
2263    o various build (mostly genmake2) changes including:
2264      - ability to build/run more easily within Cygwin and MacOS X
2265      - more complicated Makefiles with a stronger dependence on Gnu Make
2266    o pkg/seaice modifications
2267      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
2268        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
2269        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
2270      - changed proxy for geostrophic velocity and updated
2271        verification/lab_sea/results/* accordingly
2272      - removed ADI dynamic solver from pkg/seaice
2273      - replaced all occurrences of 1/CSTICE or 1/CSUICE
2274        they caused a segmentation fault under certain circumstances
2275      - removed unused field WATR
2276    o bug fix in exf-package:
2277      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
2278         now reflect that.
2279    o small fixes in the cal-package:
2280      - set reference date to first of January for the 'model'-calendar
2281      - failing of cal_CheckDate in cal_FullDate now actually results in a
2282        warning
2283    o small modifications in exf-package to increase flexibility:
2284      - change climtempfreeze from a constant to a runtime parameter that
2285        is specified in data.exf_clim (default = -1.9)
2286      - introduce runtime parameter windstressmax (default = 2.0) that is
2287        specified in data.exf
2288    o fix in pkg/thsice:
2289      - update Evap (Tsf changes) to be consistent with Latent heat flux
2290      - maintain snow precipitation unchanged (even if Tsf >=0).
2291     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
2292    
2293    checkpoint52m_post
2294    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
2295      this does not change any of the results, because myIter=0 in swfrac always
2296      lead to jwtype=2 (the default anyway), but the call makes little sense
2297      as a default
2298    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
2299    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
2300      atmospheric model (AIM) to use it ; add a "slab ocean" component.
2301    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
2302    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
2303    o extending useSingleCpuIO option to work with new exch2 I/O format
2304      - old-style, missing-tile I/O is still accessible by defining CPP
2305        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
2306    o monitor package can write to NetCDF files and/or STDOUT
2307    o fix re-definition bug in MNC_GRID_INIT_ALL()
2308    o doc/api_reference added
2309      - a framework for building an API Reference Manual using all
2310        the "protex" comments embedded in the code
2311      - see pkg/generic_advdiff, pkg/mnc for examples
2312    o MNC:
2313      - make myThid the last argument for all subroutines
2314      - new default for the grid files: NO halos
2315      - add useMNC and other run-time flags
2316      - separate per-file-group handling of the unlimited dimension
2317      - early initialization of MNC w/ flags read at the eeboot stage
2318        and lookup tables set in initialize_fixed
2319      - write all MNC output to a freshly-created directory
2320    o thermodynamics sea-ice (thsice) is now tested with testreport.
2321    o test exp. advect_cs: use the standard cs32 grid ; update output.
2322    o Added functionality to grdchk:
2323      pick global i,j,k position (or nearest wet) where to perform check.
2324    
2325    checkpoint52l_post
2326    o new land formulation:
2327      a) use ground enthalpy as prognostic variable to ensure exact
2328         energy conservation.
2329      b) account for water temperature and for latent heat of freezing
2330         in all processes (rain, run-off, ground storage)
2331      c) compute surface and ground temperature implicitly.
2332    o aim_v23 modification for new land model:
2333      a) Treat separately land / ocean / sea-ice surface fluxes
2334         to allow implicit computation of land & sea-ice surface temp.
2335      b) add snow precipitation.
2336    checkpoint52l_pre
2337    
2338    o fix problem (when 1 tile is empty) in min/max monitor.
2339    o fix bug in timeAve (u,vZetatave in common block)
2340    o no restoring terms under ice for pkg/seaice
2341    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
2342    o bug fix for pkg/seaice pickups
2343    o change MNC call locations and add coordinate attributes
2344    o mask vorticity at the corner ; affects global_ocean.cs output
2345    o fix ini_curvilinear_grid ; test CS experiments with mpi
2346    o aim.5l_cs: modify sea-ice fraction input file ; update output
2347    o exf: Adding simple range check routine for exf fields after read
2348    
2349  checkpoint52k_post  checkpoint52k_post
2350  o removed top-level directory "diags"  o removed top-level directory "diags"
2351    - we migrated these functions to pkg/timeave a long time ago    - we migrated these functions to pkg/timeave a long time ago
