4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o add a flag writePickupAtEnd (default=true) to be able to suppress
8      writing a pickup at the last timestep
9    o pkg/profiles:
10      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
11      (for "less than 32 characters name" compiler requirement)
12    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
13      conditions that have a different sampling frequency than S/T/U/V obcs
14    o pkg/diagnostics (stats-diags):
15      - fix global Min/Max in case 1 processor get only empty tiles
16    o genmake2: replace (4 times)
17         make genmake_tc_1.o >> genmake_warnings 2>&1
18      with
19         COMM="$CC $CFLAGS -c genmake_tc_1.c"
20         echo $COMM >> genmake_warnings
21         $COMM >> genmake_warnings 2>&1
22      to make genmake2 always see the value of CC as specified in the optfile.
23    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
24      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
25      - modify verification advect_cs test to test SOM-advection on CS-grid.
26    o pkg/ctrl:
27      - Rewrite of ctrl_map_ini_ecco.F,
28        introducing a generic routine (ctrl_map_ini_gen.F).
29      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
30    
31    checkpoint59n
32    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
33      number in dedicate array "hdiag":
34      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
35        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
36      - many small changes (integer format) for large number of diagnostics
37      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
38        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
39    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
40      usingSphericalGrid, this allows to define the rotated grid coordinates
41      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
42      geographical coordinates according to the inverse of the rotation defined
43      by the Euler angles, so that Coriolis parameter and online-interpolation by
44      exf works with the geographical coordinates on XC/YC/XG/YG.
45      Naturally, this feature does not work with all packages, so some
46      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
47      profiles), because there the coordinates are assumed to be regular
48      spherical grid coordinates.
49    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
50      - introduce isopycnal diffusion coefficient control.
51    o tools/adjoint_options:
52      - additional control vector components.
53    o pkg/mnc: have mnc create marginally meaning full coordinate variables
54      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
55    o pkg/mypackage:
56      - add example of read/write pickup for state-var ;
57      - add entry points to the main code for state-vars diags & write-pickup.
58    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
59      transitions for useExfYearlyFields
60      - add new subroutine that determines the file to read from for
61        use*YearlyFields = .TRUE. and .FALSE.
62      - add a verification experiment to global_with_exf that tests
63        useExfYearlyFields with USE_EXF_INTERPOLATION defined
64    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
65      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
66      subroutines (which could be generated from a template, because they are
67      almost identical), for now they are included in obcs_prescribe_read.F for
68      simplicity
69    o pkg/exf:
70      - add a little more diagnostic to exf_interp_read (in analogy to
71        mds_read_field, can be turned off with debugLevel < debugLevA=1)
72      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
73        ugly but fast by unrolling short inner loops, inserting a unroll=8
74        directive in routine lagran, and splitting a loop and making do while the
75        outermost loop (the latter requires the intoduction of index arrays)
76    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
77    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
78      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
79    o verification/seaice_obcs: updated for restart test and latest options
80    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
81      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
82      for now this is only available for the C-grid code and also within
83      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
84    
85    checkpoint59m
86    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
87      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
88    o gad_som : fix flux output (& diagnostics) to have same units as other  
89      advection scheme fluxes (was previously multiplied by deltaT).  
90    o added verification/seaice_obcs both to test seaice open boundaries
91      and to provide an example matlab scrpt for generating them
92    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
93    o pkg/salt_plume: clean up salt_plume_frac.F to
94      remove redundancy in PlumeMethod 1 and 4
95    o pkg/kpp: added saltplume diagnostics
96    o pkg/obcs and pkg/seaice:
97      - do not set uice and vice to zero when OB*icefile are unspecified
98      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
99      - moved seaice tracer obcs after call to seaice_growth
100    o pkg/salt_plume: added various options for salt plume depth
101      criterion and for vertical distribution of the salt
102    
103    checkpoint59l
104    o pkg/ptracers: new version of ptracers pickup:
105      read meta file and write only fields which are needed to restart.
106      ( same logic as main pickup file ; also using pickupStrictlyMatch )
107    o pkg/seaice:
108      - add timescale for melting due to warm mixed layer as a means of
109        setting SEAICE_availHeatFrac more conveniently
110      - add a CPP-flag/runtime parameter check for flooding algorithm
111      - reformulated availHeat in seaice_growth.F to be independent of AREA
112    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
113      unit changes
114    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
115    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
116      SX vector computer.
117    o pkg/seaice:
118      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
119        seaice forcing fields can now be read only through pkg/exf
120      - removed some unused halos
121    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
122    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
123      or U/VICE from U/VWIND before computing U/VSTRESS
124    
125    checkpoint59k
126    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
127      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
128    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
129      all experiments pass when compile with un-initialised var. checking option.
130    o added pkg/salt_plume
131    o script to test restart (for now, in MITgcm_contrib/jmc_script)
132    o pkg/seaice: new read/write pickup version.
133      read meta file and write only fields which are needed to restart.
134      ( same logic as main pickup file ; also using pickupStrictlyMatch )
135    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
136    o lab_sea.hb87: modify the domain & update output.hb87.txt :
137      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
138      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
139      process. Fixed here by closing the domain at the Northern boundary.
140    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
141    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
142      a set of consecutive levels in/from a 3-D array.
143    o pkg/ptracers:
144      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
145      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
146    
147    checkpoint59j
148    o in pkgs: dic, obcs, offline, rbcs:
149      standard way to compute coeff. for time interpolation between 2 time reccords
150      which retains full precision (& make results less dependent on compiler).
151      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
152    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
153      packages instead of reading ice cover and wind speed separately
154    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
155     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
156      to allow to compile customized code before the update)
157    o cleaning-up:
158      - fix CPP instruction syntax in pkg/obcs
159      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
160        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
161      - fix some threads issue in IO parts.
162    o pkg/dic:
163      - add tons of "_d 0" (--> much better testreports !)
164       and then update outputs of tutorial_global_oce_biogeo
165    o pkg/mom_fluxform:
166      add a special version of momentum advection intended to conserve momentum
167      next to a bathymetry step or a coastline edge. (default = off = #undef)
168    o new read/write pickup version:
169      - for now, only implemented for main (mdsio) pickup file.
170      - write out only what is needed to restart; merge pickup_nh , pickup_ph
171        and main pickup together.
172      - read meta file; read only what is needed to restart; stop if a field
173        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
174        if it make sense (even if the restart is not perfect).
175      - if no meta file, assume that pickup to read corresponds exactly to
176        a pickup that would currently be written.
177      - read pickup written in the old format (until checkpoint59i) if it
178        recognizes an old meta file (no field-list).
179      - add a meta file in exp. which starts from a pickup: 2 cases:
180        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
181         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
182        b) a meta file describing the content of the associated pickup file
183         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
184    o pkg/mdsio & pkg/rw:
185      - new routine to read a meta file ; new set of routine to read
186        Multiple-fields file (with meta file).
187    o added open boundary conditions capability for seaice
188        HSNOW, HSALT, UICE, and VICE
189    
190    checkpoint59i
191    o adjoint:
192      * fix multiDimAdvection adjoint
193        (partial recomputation problem by TAF for fVerT(:,:,kDown)
194        and comlev1 size definition (maxpass vs. max. number of tracers)
195      * verification/global_ocean.90x45x15 adjoint now tests
196        NLFS and multiDimAdvection using DST3 (=30)
197      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
198    o pkg/kpp: add "_d 0" to real constant (if missing);
199      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
200      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
201    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
202      for internal parameters related to restart process (formerly from PARAMS.h)
203      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
204    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
205      as argument. (only atm2d & obcs write_pickup have not yet been updated)
206    o pkg/monitor:
207      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
208      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
209      - account for deep Atmosphere factor and density factor (anelastic)
210    o added open boundary conditions capability for seaice HEFF and AREA
211    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
212      thermodynamics
213      - requires a little reorganization, which affects the testreport results
214        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
215        so that now the conservative form is tested
216      - add a few comments
217    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
218    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
219    o add new diagnostics to seaice: advective, diffusive fluxes (only for
220      multidim-advection, for scheme 2 they are not filled) and transports,
221      thermodynamic growth rates
222    o change units of EmPmR (inside the code, + within coupling interface)
223      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
224      Affects results @ truncation level (cg2d match) and update output of
225       experiments: lab_sea(6), global_ocean.90x40x15(10),
226      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
227      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
228      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
229      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
230    
231    checkpoint59h
232    o pkg/exf:
233      - improve vectorization by moving if-statement out of loops in
234        exf_mapfields, exf_radiation
235      - exf_bulkformulae.F: introduce 2D fields and vectorize code
236    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
237    o testreport:
238      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
239        monitor & update offline_exf_seaice exp. output.
240      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
241    o pkg/seaice:
242      - bug fix in the evp solver: boundary conditions were affected be
243        masking of zMax/zMin (changes results)
244      - minor bug fix in boundary conditions in seaice_calc_strainrates
245        (changes results for no_slip)
246      - seaice_lsr.F: make interpolation of eta dependent on boundaries
247      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
248      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
249        stress formulation and no-slip boundary conditions
250    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
251      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
252    o pkg/seaice: a first HSALT time stepping equation has been checked in
253    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
254      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
255      without requiring DO-IF statements
256    o pkg/thsice:
257      use continuous power-law function for partition of energy between lateral
258      melting/freezing and thinning/thickening ; old code using step function
259      still available with #undef THSICE_FRACEN_POWERLAW
260      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
261    o testreport: change AD testing : check against results/output_adm.txt
262      using same scripts as for forward test.
263    
264    checkpoint59g
265    o adjoint testing: in preparation for changing testreport:
266      - output format: cost and grad written on separated lines
267      - ad output results in directory "results" (instead of "results_ad")
268    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
269    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
270    o pkg/ecco: allow user defined cost function contributions
271    o testreport:
272      Allow to choose (per experiment) the list of tested output variables
273       and the main variable (used to issue a pass/FAIL ) ;
274      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
275      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
276      Also modify printing of summary:
277       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
278       b) echo the list of tested variables in the individual summary.txt of
279          each experiment.
280    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
281      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
282      (but still depend on the tile decompostion of the domain).
283    o pkg/seaice: change a discretization detail to make the B-grid code
284      "more symmetric". This change is likely to remove all "ridges/leads" that
285      where quasi-aligned with the grid in B-grid solutions. It may also be
286      the solution to the stress coupling issues with the B-grid.
287    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
288      remove .cvsignore from input dir. (since testreport no longer run here).
289    o pkg/thsice:
290     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
291     - fix reshaping of sea-ice just after advection:
292       melt all the ice only if ice-volume is too small.
293     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
294       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
295     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
296    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
297      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
298    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
299      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
300      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
301      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
302      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
303      -> update output.txt
304    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
305     this affects truncation error: -> update output.txt of exp:
306      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
307      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
308    
309    checkpoint59f
310    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
311    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
312      a bounded range (in forward mode)
313    o pkg/ecco, ctrl, autodiff and mom_common:
314     internal parameter controls, completements of implementations
315    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
316    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
317      (not seem any difference in testing results).
318    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
319       at face corners.
320    o pkg/generic_advdiff:
321     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
322      loop range indices for computing vertical advection tendency
323      and do the calculation in the interior only (no overlap) ;
324      for now, only implemented for SOM advection (to save CPU time).
325     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
326    o exch2 adjoint
327      First set of changes:
328      - add exch2 hand-written adjoint templates
329      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
330        This will require cleanup in pkg/autodiff/*.F
331        (changed routines currently kept separate in verif. code/)
332      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
333        that used to hide exch2 or cubed-sphere specific code
334        (commented via 'cph-exch2')
335    o pkg/seaice
336      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
337    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
338       output of global_ocean.cs32x15.thsice .
339    
340    checkpoint59e
341    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
342      for B-grid vector (not yet tested) and C-grid vector (<- only used
343      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
344    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
345      (#ifdef ALLOW_SALT_PLUME)
346    o gather_2d/scatter_2d: removed halo regions
347    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
348      scheme and the corresponding test case (under front_relax dir). For now,
349      only available with Skew-flux form and not yet tested in realistic set-up.
350      adjoint: store directives updated, but gradient checks deteriorated,
351      so maybe GM/Redi adjoint is now broken.
352    o seaice adjoint
353      * add AREA, HEFF, HSNOW as control variable
354        (should not change lab_sea results)
355      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
356    o pkg/seaice:
357      * added computation of saltFlux in seaice_growth;
358        For time being, sea ice salinity is assumed constant
359        contribution of snow flooding to freshening of sea ice is neglected.
360        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
361        defaults to 0.0 in order to maintain backward compatibility.
362        Typical values for SEAICE_salinity are 4 to 10 g/kg.
363      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
364      * added SEAICE_availHeatFrac, which specifies fraction of surface level
365        heat content used to melt or grow ice
366      * commented out cap of HICE: it helps keep ice thinner
367      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
368      * applied OBCS T/S mask to HEFFM sea ice mask
369    
370    checkpoint59d
371    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
372     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
373     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
374    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
375     and change default value of parameter "GM_Small_Number";
376     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
377       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
378       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
379    o pkg/ecco: cost function when applying pkg/smooth to controls
380    o pkg/ctrl: add forcingPrecond run time parameter
381    o pkg/seaice:
382     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
383     - fix bug in metric terms of u-equation in LSR solver (implicit part),
384       changes verification/lab_sea
385     - rearrange implicit part of u-equation in LSR solver to make it easier to
386       read, understand, and debug. This causes changes at the truncation level.
387     - fix (serious) bug in the boundary conditions (sign error in the implicit
388       part) of the LSR solver. Changes all LSR results.
389     - fixed problem with HSNOW initialization to avoid thick snow when AREA
390       is initilized with small values - does not change lab_sea results.
391     - added HsnowFile initialization capability
392    o pkg/smooth: addition to model/src and pkg/ctrl so allow
393     initialization of pkg/smooth and application to control vector
394    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
395    o dependencies: pkg/profiles requires pkg/cal
396    o pkg/profiles:
397     - added option ALLOW_PROFILES_GENERICGRID
398         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
399         that interpolation information (grid points and coefficients) is provided
400         within the netcdf input files.
401         -> sample matlab scripts can be found in MITgcm_contrib/gael
402         that allow you to prepare netcdf input files.
403     - also modified: cleaner include statements, cleaner error print statements,
404       cleaner stops when error, and more tests of the netcdf input files consistency.
405    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
406    o pkg/seaice:
407     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
408       requires a new routine: seaice_diagnostics_fill.F
409     - make sure that seaice does not move if not forced (pressure replacement
410       method, Hibler and Ip, 1995), changes results
411     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
412     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
413       It is turned off by default (=-1.), because it changes the results.
414     - make it possible to read AREA from a file, too.
415    
416    checkpoint59c
417    o add S/R and diagnostics for oceanic mixed-layer depth
418    o move GMRedi call after all vertical mixing schemes (including KPP)
419    o pkg/thsice:
420     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
421      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
422    o pkg/obcs:
423     - bug fix for balance code
424    o pkg/seaice:
425      - allow values of SEAICE_elasticParm > 1
426      - add new parameter SEAICE_evpTauRelax as an alternative
427        to SEAICE_elasticParm
428      - make lsr boundary conditions free slip (by default), changes result
429      - add code for no slip boundary conditions for lsr
430      - set minimum of zeta to zero (and not 4e8) (changes results)
431      - add a cap on AREA after advecting AREA if seaice_growth is not called
432    o change calculation of Visbeck K:
433      - no longer depend on tapering scheme; instead, compute slope (limited
434        by GM_maxSlope). this is equivalent to what was comuted before with
435        clipping or linear tappering.
436      - fix vertical averaging (wrong by 1/2 level)
437      - leave the old version (but will not be maintained) within
438        #ifdef OLD_VISBECK_CALC / #endif
439      - update output of exp. ideal_2D_oce
440    o change error catch in calc_r_star to improve vectorization
441    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
442      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
443    o adjoint:
444      Re-organized adjoint checkpointing according to Matt Mazloff
445      (but with modifs/completions/cleanups)
446      Storing is now bundled into large arrays to optimized I/O
447      (and second step in cleanup of the_main_loop)
448    
449    checkpoint59b
450    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
451      - export/import (between ocean & coupler) fields needed for ocean DIC.
452    o pkg/seaice:
453      - get rid of three more exchanges seaice_calc_viscosities (required
454        different loop boundaries in seaice_lsr and seaice_ocean_stress)
455      - bug fix in seaice_ocean_stress (update of lab_sea required)
456      - reduce loop boundaries to necessary minimum also in seaice_evp
457      - go back to the old way of computing deltaC/Z as the adjoint likes that
458        better
459    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
460      passive tracer to an Age Tracer) + update output.txt
461    o pkg/exf:
462      - implement A-grid / C-grid selection for wind-stress input files.
463      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
464      for now, in exf_bulk_largeyeager04.F only :
465      - change implementation for case where windspeed + 2. components wind-stress
466        are read-in. AND use rhoConstFresh to convert evap.
467    o pkg/seaice:
468      - use correct EXCH_UV for wind-forcing (on A-grid).
469      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
470        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
471    o pkg/exf:
472      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
473      EXF_INTERPOLATION:
474      - merge global_with_exf/code version of exf_interp_read.F
475        to the main code ;
476      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
477        reading the file ; Important: This options needs to be defined to recover
478        previous code.
479        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
480      - no longer loose real*8 precision along the way when using exf_iprec=64.
481    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
482      - change discretisation of evp-solver in order to avoid another exchange
483        (changes lab_sea) and clean up a little
484      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
485        help the adjoint (this also changes the results slightly)
486      - add a few "_d 0" where they had been missing in seaice_evp.F
487      - cleaning up: remove unused seaice_calc_rhs.F
488    o pkg/exf: some cleaning-up:
489      - change various "constants" into runtime parameters
490      - cleaned-up Large&Yeager04 routine which should eventually
491        replace exf_bulkformulae.F (changed names of S/R and CPP)
492        and merged various ALLOW_ATM_WIND options
493     only used with thsice pkg (in thsice_get_exf.F):
494      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
495        which are used when useStabilityFct_overIce=TRUE (= the default)
496      - change default values of ice & snow emissivity and scale downward LW
497        by ice & snow emissivity.
498    o pkg/thsice:
499     fix few little problems, in thsice_calc_thickn.F:
500      - growth vertically (and not laterally) if iceFrac == iceMaskMax
501      - melt only laterally if hIce < hThinIce (as the comments say)
502      and in thsice_extend.F:
503      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
504      - start to form ice as soon as the minimum ice-volume is reachable.
505     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
506      and cpl_aim+ocn
507    o pkg/kpp
508     - move computation of surface related input fields to KPP into a new
509       subroutine kpp_forcing_surf.F
510     - remove wrong (within bi,bj loops) EXCH calls.
511     - little cleaning (add argument myThid in last position, cvs header ...)
512     - for now, fix conservation problem by exchanging KPPviscAz (may not
513       be the best fix)
514    o pkg/seaice
515     - check for inconsistent evp parameter/cpp-flag combination
516     - remove leftover errIO flat for obsolete name list error handling
517    o OpenAD
518     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
519    
520    checkpoint59a
521    o pkg/seaice: some parameter clarifications and a little bit of clean up
522    o pkg/thsice: rename run-time parameters:
523       himin       -> hIceMin
524       himin0      -> hThinIce
525       hihig       -> hThickIce
526       i0          -> i0swFrac
527       transCoef   -> bMeltCoef
528       frac_energy -> fracMelting
529      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
530       with default values (for now) that do not change the results.
531      remove old version of thsice vars advection in pkg/seaice.
532    o in FFIELDS.h:
533      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
534      - make pLoad & sIceLoad always available (but still only used if
535         ATMOSPHERIC_LOADING is #define).
536    o pkg/kpp: replaced _KPP_RL with _RL
537    o bug fixes for vertical diffusivity computations when both KPP and
538        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
539        are no longer updating the vertical diffusivity array
540        (passed as argument) but are (re-) setting those arrays.
541    o pkg/seaice: fix bug in evp solver, while doing that
542      - change (improve?) discretization of stress computations for both
543        cgrid-lsr and evp solver
544      - add a new routine to compute strain rates
545      - the above changes lab_sea results
546      - add no slip conditions for evp solver (off by default), lsr-version
547        may follow
548      - fix exchange for shear at Z-points (does not change lab_sea)
549      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
550        (to force the user to pick a time step since there is not "safe" way
551        of choosing it)
552      - add principal stress diagnostics
553      - rearrange fields for evp a little to avoid having to call a: too many
554        exchanges and b: exchanges for stress trensor components which we do
555        not have.
556      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
557        of evp, complete rewrite for lsr case (latter is does not yet work
558        in all cases)
559    o pkg/kpp: add code to have mixing in shelf ice caverns
560      - add myThid to all kpp routines (long overdue)
561    
562    checkpoint59
563    o pkg/exf:
564      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
565        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
566      - move exf header files from lower_case.h to UPPER_CASE.h ;
567        add missing cvs Header & Name
568      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
569      - add namelist param. selectStressGridPosition, exf_monFreq
570      - retire many _CLIM routines, and remove data.exf_clim
571        + params moved to data.exf
572        + climsst, climsss now handled by exf_set_gen, i.e.
573          climss?period=0 refers to constant field,
574          climss?period=-12 to monthly forcing
575      - split up namelists in data.exf
576    o pkg/seaice:
577      - remove seaice_exch and seaice_exch_uv
578      - remove superfluous exchange of theta
579      - add myThid to seaice_budget_ocean/ice
580      - add new interface for atmospheric wind forcing (C-grid only)
581        + new routine
582        + two new field (taux, tauy for stress over ice)
583        + removed one global field (DAIRN) for C-grid case only
584    o pkg/thsise
585      - 2nd set of modifs for thsice adjoint in conjunction with exf
586    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
587    
588    checkpoint58y_post
589    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
590      vertical diffusivity, similar to that in MOM4; turned on using
591      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
592      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
593    o Added capability for 3D specification of background vertical diffusion
594      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
595      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
596      "data" file that contains the 3D vertical diffusivity coefficients.
597    o ice dynamics (pkg/seaice) with thsice thermodynamics:
598      - add code within pkg thsice to advect & diffuse sea-ice fields
599      similar to (and will replace) what has been added in  seaice_advdiff.F,
600      but: - conserving Mass, Heat & Salt.
601           - better when using non-linear advection scheme (not yet fully tested)
602           - can also be used in atmospheric set-up (for now, only the diffusion).
603    
604    checkpoint58x_post
605    o IO option for global-file compact format:
606      - add options when generating topology (utils/exch2/matlab-topology-generator)
607      - add I/O capability (pkg/mdsio).
608      - adapt utils/matlab/rdmds.m to read this format.
609      for now long-line format not yet supported by pkg/mdsio (& exch2).
610    o shelfice: add a few diagnostics
611    
612    checkpoint58w_post
613    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
614      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
615      (and replace horiVertRatio in NH code).
616      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
617                         and tutorial_plume_on_slope (sensitive to truncation)
618    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
619      directly to drive seaice model (C-grid only)
620    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
621     - reintroduce computation of wind from stress,
622     - compute tau (in exf_bulkformulae.F) from windstress averaged to
623       mass points to avoid tau = 0
624     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
625    o rdmnc.m: make it work with "global" files created with gluemnc
626    o rdmnc.m : some improvements in dealing with singleton dimension
627      (tested on all testreport mnc output files).
628    o genmake2: disable pkg/profiles if netcdf test fails.
629    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
630    o move call to cal_readparms up to make calendar parameters/variable available
631      to all packages
632    
633    checkpoint58v_post
634    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
635      useDynP_inEos_Zc tested.
636    o pkg/exf: changes to properly interpolate/mask/scale initial fields
637    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
638      and portions thereof.  See read_cs.txt for description and examples.
639    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
640      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
641      following the great-circle arc between those 2 points.
642    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
643      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
644    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
645     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
646     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
647     - still needs work (not working with some options ; efficiency to improve)
648       and serious testing.
649     - use this scheme for temperature & salinity in 2 advection test exp.:
650       advect_xy & advect_xz, respectively.
651    
652    checkpoint58u_post
653    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
654    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
655    o testreport: add option "-skipdir" to skip some test.
656    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
657      momentum calculation.
658    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
659    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
660      remove checkpoint.F and the_correction_step.F (no longer used);
661      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
662    o add option (linFSConserveTr) to correct for tracer source/sink due to
663      Linear Free surface
664    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
665    o pkg/thsice: fix reading mnc-pickups
666    
667    checkpoint58t_post
668    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
669    o pkg/mdsio:
670     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
671       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
672       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
673     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
674     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
675       either MDS_READ_FIELD or MDS_WRITE_FIELD )
676     - new S/R (to replace MDSWRITEMETA), which allows to write more
677       informations (variable names, time ...) to meta files.
678     - modify rdmds.m to give back the meta file content.
679    o pkg/diagnostics: change vertical interpolation to be safer, and more
680       flexible (define p-levels to interpolate to in data.diagnostics);
681      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
682       diagnostic pointer.
683    o pkg/seaice: more cleaning up of seaice_growth, added many comments
684    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
685    o fix multi-category seaice:
686     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
687       SEAICE_MULTICATEGORY
688     - fix short wave heat flux
689    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
690       and allow to use EVP solver. Change forward lab_sea: test both EVP
691       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
692    o Initial check-in of lab_sea adjoint
693      (very similar to natl_box_adjoint/code_seaice)
694      * used C-grid and EVP solver
695      * used KPP, GM/Redi
696      * uses inAdExact=.TRUE.
697      * gradient checks fail for both ADM and TLM
698        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
699        f.d. gradients actually seem more problematic than ADM, TLM gradients;
700        issue is related to forward mismatch between g77 an ifort
701    o pkg/seaice: overhaul of thermodynamics
702     - growth.F and groatb.F are replaced by new routine seaice_growth.F
703     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
704     - move a few global fields out of SEAICE.h into seaice_growth.F and
705       make them 2D (FICE/QNETO/ ...)
706     - remove FO (it is the same as QNETO)
707     - introduce a few local fields to avoid modifying external fields such
708       as atemp, etc.

710    checkpoint58s_post
711    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
712      changed exf_set_gen.F so that
713        genperiod=0 means input file is one time-constant field and
714        genperiod=-12 means input file contains 12 monthly means
715    o CG2D: use pre-computed solver main-diagonal (stored in common block);
716      this affects truncation error ; generate new output file for exp. which
717      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
718        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
719        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
720        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
721        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
722        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
723    o start implementation of deep-atmosphere and anelastic formulation
724    o verification: remove 2nd copy of input files and use script "prepare_run"
725      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
726    o mom_common/vecinv/fluxform: fix a few initialisation isssues
727    o profiles: fix for multithreaded case
728    
729    o diagnostics: rename few diags:
730      s/'PRESSURE'/'RCENTER '/g
731      s/'TICE    '/'oceFreez'/g
732      s/'TAUX    '/'oceTAUX '/g
733      s/'TAUY    '/'oceTAUY '/g
734      s/'SWFLUX  '/'oceQsw  '/g
735      s/DIFx/DFxE/g
736      s/DIFy/DFyE/g
737      and add few ocean-forcing diagnostics:
738      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
739    o modifications to pkg/seaice/growth.F and budget.F, which change results of
740      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
741      as actual snow thickness.  It now refers everywhere to effective snow
742      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
743    
744    checkpoint58r_post
745    o modifications to pkg/seaice/growth.F, which change results of
746      lab_sea experiment: fixes pertain to melting snow over open water, to
747      masking EVAP under sea ice, and to using the correct AREA variable for
748      computations of EVAP, PRECIP, HSNOW, and GHEFF
749    o add ability to read bathy, salt, and theta using MNC (off by def)
750    o add flooding algorithm and advection of HSNOW for pkg/seaice;
751      both are turned off by default and do no change any results
752    o seaice advection with pkg/thsice: a step toward the use of non-linear
753      advection scheme, but #ifdef or commented out for now (requires more EXCH).
754    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
755      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
756      in natl_box (affects results @ truncation level: update output.txt)
757    o multi-threading and IO:
758      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
759      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
760        (needed to work with SingleCpuIO): tested in all verif. exp.
761    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
762      affects the results (but none of the verification test uses this scheme).
763    o Adding some pkg/diagnostics capability to pkg/seaice
764      (will certainly be subject to changes)
765    o ctrl: adding new control variables:
766      lwflux, lwdown, evap, snowprecip, apressure, runoff
767    
768  checkpoint58q_post  checkpoint58q_post
769  o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up  o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
770    1/6-deg Southern Ocean configuration by 8% on IBM Datastar and    1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
