4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
8      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
9    o verification/seaice_obcs: updated for restart test and latest options
10    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
11      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
12      for now this is only available for the C-grid code and also within
13      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
14    
15    checkpoint59m
16    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
17      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
18    o gad_som : fix flux output (& diagnostics) to have same units as other  
19      advection scheme fluxes (was previously multiplied by deltaT).  
20    o added verification/seaice_obcs both to test seaice open boundaries
21      and to provide an example matlab scrpt for generating them
22    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
23    o pkg/salt_plume: clean up salt_plume_frac.F to
24      remove redundancy in PlumeMethod 1 and 4
25    o pkg/kpp: added saltplume diagnostics
26    o pkg/obcs and pkg/seaice:
27      - do not set uice and vice to zero when OB*icefile are unspecified
28      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
29      - moved seaice tracer obcs after call to seaice_growth
30    o pkg/salt_plume: added various options for salt plume depth
31      criterion and for vertical distribution of the salt
32    
33    checkpoint59l
34    o pkg/ptracers: new version of ptracers pickup:
35      read meta file and write only fields which are needed to restart.
36      ( same logic as main pickup file ; also using pickupStrictlyMatch )
37    o pkg/seaice:
38      - add timescale for melting due to warm mixed layer as a means of
39        setting SEAICE_availHeatFrac more conveniently
40      - add a CPP-flag/runtime parameter check for flooding algorithm
41      - reformulated availHeat in seaice_growth.F to be independent of AREA
42    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
43      unit changes
44    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
45    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
46      SX vector computer.
47    o pkg/seaice:
48      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
49        seaice forcing fields can now be read only through pkg/exf
50      - removed some unused halos
51    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
52    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
53      or U/VICE from U/VWIND before computing U/VSTRESS
54    
55    checkpoint59k
56    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
57      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
58    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
59      all experiments pass when compile with un-initialised var. checking option.
60    o added pkg/salt_plume
61    o script to test restart (for now, in MITgcm_contrib/jmc_script)
62    o pkg/seaice: new read/write pickup version.
63      read meta file and write only fields which are needed to restart.
64      ( same logic as main pickup file ; also using pickupStrictlyMatch )
65    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
66    o lab_sea.hb87: modify the domain & update output.hb87.txt :
67      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
68      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
69      process. Fixed here by closing the domain at the Northern boundary.
70    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
71    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
72      a set of consecutive levels in/from a 3-D array.
73    o pkg/ptracers:
74      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
75      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
76    
77    checkpoint59j
78    o in pkgs: dic, obcs, offline, rbcs:
79      standard way to compute coeff. for time interpolation between 2 time reccords
80      which retains full precision (& make results less dependent on compiler).
81      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
82    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
83      packages instead of reading ice cover and wind speed separately
84    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
85     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
86      to allow to compile customized code before the update)
87    o cleaning-up:
88      - fix CPP instruction syntax in pkg/obcs
89      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
90        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
91      - fix some threads issue in IO parts.
92    o pkg/dic:
93      - add tons of "_d 0" (--> much better testreports !)
94       and then update outputs of tutorial_global_oce_biogeo
95    o pkg/mom_fluxform:
96      add a special version of momentum advection intended to conserve momentum
97      next to a bathymetry step or a coastline edge. (default = off = #undef)
98    o new read/write pickup version:
99      - for now, only implemented for main (mdsio) pickup file.
100      - write out only what is needed to restart; merge pickup_nh , pickup_ph
101        and main pickup together.
102      - read meta file; read only what is needed to restart; stop if a field
103        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
104        if it make sense (even if the restart is not perfect).
105      - if no meta file, assume that pickup to read corresponds exactly to
106        a pickup that would currently be written.
107      - read pickup written in the old format (until checkpoint59i) if it
108        recognizes an old meta file (no field-list).
109      - add a meta file in exp. which starts from a pickup: 2 cases:
110        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
111         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
112        b) a meta file describing the content of the associated pickup file
113         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
114    o pkg/mdsio & pkg/rw:
115      - new routine to read a meta file ; new set of routine to read
116        Multiple-fields file (with meta file).
117    o added open boundary conditions capability for seaice
118        HSNOW, HSALT, UICE, and VICE
119    
120    checkpoint59i
121    o adjoint:
122      * fix multiDimAdvection adjoint
123        (partial recomputation problem by TAF for fVerT(:,:,kDown)
124        and comlev1 size definition (maxpass vs. max. number of tracers)
125      * verification/global_ocean.90x45x15 adjoint now tests
126        NLFS and multiDimAdvection using DST3 (=30)
127      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
128    o pkg/kpp: add "_d 0" to real constant (if missing);
129      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
130      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
131    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
132      for internal parameters related to restart process (formerly from PARAMS.h)
133      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
134    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
135      as argument. (only atm2d & obcs write_pickup have not yet been updated)
136    o pkg/monitor:
137      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
138      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
139      - account for deep Atmosphere factor and density factor (anelastic)
140    o added open boundary conditions capability for seaice HEFF and AREA
141    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
142      thermodynamics
143      - requires a little reorganization, which affects the testreport results
144        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
145        so that now the conservative form is tested
146      - add a few comments
147    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
148    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
149    o add new diagnostics to seaice: advective, diffusive fluxes (only for
150      multidim-advection, for scheme 2 they are not filled) and transports,
151      thermodynamic growth rates
152    o change units of EmPmR (inside the code, + within coupling interface)
153      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
154      Affects results @ truncation level (cg2d match) and update output of
155       experiments: lab_sea(6), global_ocean.90x40x15(10),
156      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
157      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
158      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
159      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
160    
161    checkpoint59h
162    o pkg/exf:
163      - improve vectorization by moving if-statement out of loops in
164        exf_mapfields, exf_radiation
165      - exf_bulkformulae.F: introduce 2D fields and vectorize code
166    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
167    o testreport:
168      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
169        monitor & update offline_exf_seaice exp. output.
170      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
171    o pkg/seaice:
172      - bug fix in the evp solver: boundary conditions were affected be
173        masking of zMax/zMin (changes results)
174      - minor bug fix in boundary conditions in seaice_calc_strainrates
175        (changes results for no_slip)
176      - seaice_lsr.F: make interpolation of eta dependent on boundaries
177      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
178      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
179        stress formulation and no-slip boundary conditions
180    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
181      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
182    o pkg/seaice: a first HSALT time stepping equation has been checked in
183    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
184      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
185      without requiring DO-IF statements
186    o pkg/thsice:
187      use continuous power-law function for partition of energy between lateral
188      melting/freezing and thinning/thickening ; old code using step function
189      still available with #undef THSICE_FRACEN_POWERLAW
190      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
191    o testreport: change AD testing : check against results/output_adm.txt
192      using same scripts as for forward test.
193    
194    checkpoint59g
195    o adjoint testing: in preparation for changing testreport:
196      - output format: cost and grad written on separated lines
197      - ad output results in directory "results" (instead of "results_ad")
198    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
199    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
200    o pkg/ecco: allow user defined cost function contributions
201    o testreport:
202      Allow to choose (per experiment) the list of tested output variables
203       and the main variable (used to issue a pass/FAIL ) ;
204      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
205      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
206      Also modify printing of summary:
207       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
208       b) echo the list of tested variables in the individual summary.txt of
209          each experiment.
210    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
211      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
212      (but still depend on the tile decompostion of the domain).
213    o pkg/seaice: change a discretization detail to make the B-grid code
214      "more symmetric". This change is likely to remove all "ridges/leads" that
215      where quasi-aligned with the grid in B-grid solutions. It may also be
216      the solution to the stress coupling issues with the B-grid.
217    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
218      remove .cvsignore from input dir. (since testreport no longer run here).
219    o pkg/thsice:
220     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
221     - fix reshaping of sea-ice just after advection:
222       melt all the ice only if ice-volume is too small.
223     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
224       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
225     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
226    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
227      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
228    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
229      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
230      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
231      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
232      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
233      -> update output.txt
234    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
235     this affects truncation error: -> update output.txt of exp:
236      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
237      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
238    
239    checkpoint59f
240    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
241    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
242      a bounded range (in forward mode)
243    o pkg/ecco, ctrl, autodiff and mom_common:
244     internal parameter controls, completements of implementations
245    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
246    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
247      (not seem any difference in testing results).
248    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
249       at face corners.
250    o pkg/generic_advdiff:
251     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
252      loop range indices for computing vertical advection tendency
253      and do the calculation in the interior only (no overlap) ;
254      for now, only implemented for SOM advection (to save CPU time).
255     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
256    o exch2 adjoint
257      First set of changes:
258      - add exch2 hand-written adjoint templates
259      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
260        This will require cleanup in pkg/autodiff/*.F
261        (changed routines currently kept separate in verif. code/)
262      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
263        that used to hide exch2 or cubed-sphere specific code
264        (commented via 'cph-exch2')
265    o pkg/seaice
266      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
267    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
268       output of global_ocean.cs32x15.thsice .
269    
270    checkpoint59e
271    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
272      for B-grid vector (not yet tested) and C-grid vector (<- only used
273      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
274    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
275      (#ifdef ALLOW_SALT_PLUME)
276    o gather_2d/scatter_2d: removed halo regions
277    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
278      scheme and the corresponding test case (under front_relax dir). For now,
279      only available with Skew-flux form and not yet tested in realistic set-up.
280      adjoint: store directives updated, but gradient checks deteriorated,
281      so maybe GM/Redi adjoint is now broken.
282    o seaice adjoint
283      * add AREA, HEFF, HSNOW as control variable
284        (should not change lab_sea results)
285      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
286    o pkg/seaice:
287      * added computation of saltFlux in seaice_growth;
288        For time being, sea ice salinity is assumed constant
289        contribution of snow flooding to freshening of sea ice is neglected.
290        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
291        defaults to 0.0 in order to maintain backward compatibility.
292        Typical values for SEAICE_salinity are 4 to 10 g/kg.
293      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
294      * added SEAICE_availHeatFrac, which specifies fraction of surface level
295        heat content used to melt or grow ice
296      * commented out cap of HICE: it helps keep ice thinner
297      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
298      * applied OBCS T/S mask to HEFFM sea ice mask
299    
300    checkpoint59d
301    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
302     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
303     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
304    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
305     and change default value of parameter "GM_Small_Number";
306     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
307       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
308       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
309    o pkg/ecco: cost function when applying pkg/smooth to controls
310    o pkg/ctrl: add forcingPrecond run time parameter
311    o pkg/seaice:
312     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
313     - fix bug in metric terms of u-equation in LSR solver (implicit part),
314       changes verification/lab_sea
315     - rearrange implicit part of u-equation in LSR solver to make it easier to
316       read, understand, and debug. This causes changes at the truncation level.
317     - fix (serious) bug in the boundary conditions (sign error in the implicit
318       part) of the LSR solver. Changes all LSR results.
319     - fixed problem with HSNOW initialization to avoid thick snow when AREA
320       is initilized with small values - does not change lab_sea results.
321     - added HsnowFile initialization capability
322    o pkg/smooth: addition to model/src and pkg/ctrl so allow
323     initialization of pkg/smooth and application to control vector
324    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
325    o dependencies: pkg/profiles requires pkg/cal
326    o pkg/profiles:
327     - added option ALLOW_PROFILES_GENERICGRID
328         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
329         that interpolation information (grid points and coefficients) is provided
330         within the netcdf input files.
331         -> sample matlab scripts can be found in MITgcm_contrib/gael
332         that allow you to prepare netcdf input files.
333     - also modified: cleaner include statements, cleaner error print statements,
334       cleaner stops when error, and more tests of the netcdf input files consistency.
335    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
336    o pkg/seaice:
337     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
338       requires a new routine: seaice_diagnostics_fill.F
339     - make sure that seaice does not move if not forced (pressure replacement
340       method, Hibler and Ip, 1995), changes results
341     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
342     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
343       It is turned off by default (=-1.), because it changes the results.
344     - make it possible to read AREA from a file, too.
345    
346    checkpoint59c
347    o add S/R and diagnostics for oceanic mixed-layer depth
348    o move GMRedi call after all vertical mixing schemes (including KPP)
349    o pkg/thsice:
350     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
351      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
352    o pkg/obcs:
353     - bug fix for balance code
354    o pkg/seaice:
355      - allow values of SEAICE_elasticParm > 1
356      - add new parameter SEAICE_evpTauRelax as an alternative
357        to SEAICE_elasticParm
358      - make lsr boundary conditions free slip (by default), changes result
359      - add code for no slip boundary conditions for lsr
360      - set minimum of zeta to zero (and not 4e8) (changes results)
361      - add a cap on AREA after advecting AREA if seaice_growth is not called
362    o change calculation of Visbeck K:
363      - no longer depend on tapering scheme; instead, compute slope (limited
364        by GM_maxSlope). this is equivalent to what was comuted before with
365        clipping or linear tappering.
366      - fix vertical averaging (wrong by 1/2 level)
367      - leave the old version (but will not be maintained) within
368        #ifdef OLD_VISBECK_CALC / #endif
369      - update output of exp. ideal_2D_oce
370    o change error catch in calc_r_star to improve vectorization
371    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
372      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
373    o adjoint:
374      Re-organized adjoint checkpointing according to Matt Mazloff
375      (but with modifs/completions/cleanups)
376      Storing is now bundled into large arrays to optimized I/O
377      (and second step in cleanup of the_main_loop)
378    
379    checkpoint59b
380    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
381      - export/import (between ocean & coupler) fields needed for ocean DIC.
382    o pkg/seaice:
383      - get rid of three more exchanges seaice_calc_viscosities (required
384        different loop boundaries in seaice_lsr and seaice_ocean_stress)
385      - bug fix in seaice_ocean_stress (update of lab_sea required)
386      - reduce loop boundaries to necessary minimum also in seaice_evp
387      - go back to the old way of computing deltaC/Z as the adjoint likes that
388        better
389    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
390      passive tracer to an Age Tracer) + update output.txt
391    o pkg/exf:
392      - implement A-grid / C-grid selection for wind-stress input files.
393      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
394      for now, in exf_bulk_largeyeager04.F only :
395      - change implementation for case where windspeed + 2. components wind-stress
396        are read-in. AND use rhoConstFresh to convert evap.
397    o pkg/seaice:
398      - use correct EXCH_UV for wind-forcing (on A-grid).
399      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
400        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
401    o pkg/exf:
402      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
403      EXF_INTERPOLATION:
404      - merge global_with_exf/code version of exf_interp_read.F
405        to the main code ;
406      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
407        reading the file ; Important: This options needs to be defined to recover
408        previous code.
409        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
410      - no longer loose real*8 precision along the way when using exf_iprec=64.
411    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
412      - change discretisation of evp-solver in order to avoid another exchange
413        (changes lab_sea) and clean up a little
414      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
415        help the adjoint (this also changes the results slightly)
416      - add a few "_d 0" where they had been missing in seaice_evp.F
417      - cleaning up: remove unused seaice_calc_rhs.F
418    o pkg/exf: some cleaning-up:
419      - change various "constants" into runtime parameters
420      - cleaned-up Large&Yeager04 routine which should eventually
421        replace exf_bulkformulae.F (changed names of S/R and CPP)
422        and merged various ALLOW_ATM_WIND options
423     only used with thsice pkg (in thsice_get_exf.F):
424      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
425        which are used when useStabilityFct_overIce=TRUE (= the default)
426      - change default values of ice & snow emissivity and scale downward LW
427        by ice & snow emissivity.
428    o pkg/thsice:
429     fix few little problems, in thsice_calc_thickn.F:
430      - growth vertically (and not laterally) if iceFrac == iceMaskMax
431      - melt only laterally if hIce < hThinIce (as the comments say)
432      and in thsice_extend.F:
433      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
434      - start to form ice as soon as the minimum ice-volume is reachable.
435     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
436      and cpl_aim+ocn
437    o pkg/kpp
438     - move computation of surface related input fields to KPP into a new
439       subroutine kpp_forcing_surf.F
440     - remove wrong (within bi,bj loops) EXCH calls.
441     - little cleaning (add argument myThid in last position, cvs header ...)
442     - for now, fix conservation problem by exchanging KPPviscAz (may not
443       be the best fix)
444    o pkg/seaice
445     - check for inconsistent evp parameter/cpp-flag combination
446     - remove leftover errIO flat for obsolete name list error handling
447    o OpenAD
448     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
449    
450    checkpoint59a
451    o pkg/seaice: some parameter clarifications and a little bit of clean up
452    o pkg/thsice: rename run-time parameters:
453       himin       -> hIceMin
454       himin0      -> hThinIce
455       hihig       -> hThickIce
456       i0          -> i0swFrac
457       transCoef   -> bMeltCoef
458       frac_energy -> fracMelting
459      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
460       with default values (for now) that do not change the results.
461      remove old version of thsice vars advection in pkg/seaice.
462    o in FFIELDS.h:
463      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
464      - make pLoad & sIceLoad always available (but still only used if
465         ATMOSPHERIC_LOADING is #define).
466    o pkg/kpp: replaced _KPP_RL with _RL
467    o bug fixes for vertical diffusivity computations when both KPP and
468        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
469        are no longer updating the vertical diffusivity array
470        (passed as argument) but are (re-) setting those arrays.
471    o pkg/seaice: fix bug in evp solver, while doing that
472      - change (improve?) discretization of stress computations for both
473        cgrid-lsr and evp solver
474      - add a new routine to compute strain rates
475      - the above changes lab_sea results
476      - add no slip conditions for evp solver (off by default), lsr-version
477        may follow
478      - fix exchange for shear at Z-points (does not change lab_sea)
479      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
480        (to force the user to pick a time step since there is not "safe" way
481        of choosing it)
482      - add principal stress diagnostics
483      - rearrange fields for evp a little to avoid having to call a: too many
484        exchanges and b: exchanges for stress trensor components which we do
485        not have.
486      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
487        of evp, complete rewrite for lsr case (latter is does not yet work
488        in all cases)
489    o pkg/kpp: add code to have mixing in shelf ice caverns
490      - add myThid to all kpp routines (long overdue)
491    
492    checkpoint59
493    o pkg/exf:
494      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
495        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
496      - move exf header files from lower_case.h to UPPER_CASE.h ;
497        add missing cvs Header & Name
498      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
499      - add namelist param. selectStressGridPosition, exf_monFreq
500      - retire many _CLIM routines, and remove data.exf_clim
501        + params moved to data.exf
502        + climsst, climsss now handled by exf_set_gen, i.e.
503          climss?period=0 refers to constant field,
504          climss?period=-12 to monthly forcing
505      - split up namelists in data.exf
506    o pkg/seaice:
507      - remove seaice_exch and seaice_exch_uv
508      - remove superfluous exchange of theta
509      - add myThid to seaice_budget_ocean/ice
510      - add new interface for atmospheric wind forcing (C-grid only)
511        + new routine
512        + two new field (taux, tauy for stress over ice)
513        + removed one global field (DAIRN) for C-grid case only
514    o pkg/thsise
515      - 2nd set of modifs for thsice adjoint in conjunction with exf
516    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
517    
518    checkpoint58y_post
519    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
520      vertical diffusivity, similar to that in MOM4; turned on using
521      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
522      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
523    o Added capability for 3D specification of background vertical diffusion
524      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
525      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
526      "data" file that contains the 3D vertical diffusivity coefficients.
527    o ice dynamics (pkg/seaice) with thsice thermodynamics:
528      - add code within pkg thsice to advect & diffuse sea-ice fields
529      similar to (and will replace) what has been added in  seaice_advdiff.F,
530      but: - conserving Mass, Heat & Salt.
531           - better when using non-linear advection scheme (not yet fully tested)
532           - can also be used in atmospheric set-up (for now, only the diffusion).
533    
534    checkpoint58x_post
535    o IO option for global-file compact format:
536      - add options when generating topology (utils/exch2/matlab-topology-generator)
537      - add I/O capability (pkg/mdsio).
538      - adapt utils/matlab/rdmds.m to read this format.
539      for now long-line format not yet supported by pkg/mdsio (& exch2).
540    o shelfice: add a few diagnostics
541    
542    checkpoint58w_post
543    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
544      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
545      (and replace horiVertRatio in NH code).
546      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
547                         and tutorial_plume_on_slope (sensitive to truncation)
548    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
549      directly to drive seaice model (C-grid only)
550    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
551     - reintroduce computation of wind from stress,
552     - compute tau (in exf_bulkformulae.F) from windstress averaged to
553       mass points to avoid tau = 0
554     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
555    o rdmnc.m: make it work with "global" files created with gluemnc
556    o rdmnc.m : some improvements in dealing with singleton dimension
557      (tested on all testreport mnc output files).
558    o genmake2: disable pkg/profiles if netcdf test fails.
559    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
560    o move call to cal_readparms up to make calendar parameters/variable available
561      to all packages
562    
563    checkpoint58v_post
564    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
565      useDynP_inEos_Zc tested.
566    o pkg/exf: changes to properly interpolate/mask/scale initial fields
567    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
568      and portions thereof.  See read_cs.txt for description and examples.
569    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
570      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
571      following the great-circle arc between those 2 points.
572    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
573      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
574    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
575     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
576     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
577     - still needs work (not working with some options ; efficiency to improve)
578       and serious testing.
579     - use this scheme for temperature & salinity in 2 advection test exp.:
580       advect_xy & advect_xz, respectively.
581    
582    checkpoint58u_post
583    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
584    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
585    o testreport: add option "-skipdir" to skip some test.
586    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
587      momentum calculation.
588    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
589    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
590      remove checkpoint.F and the_correction_step.F (no longer used);
591      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
592    o add option (linFSConserveTr) to correct for tracer source/sink due to
593      Linear Free surface
594    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
595    o pkg/thsice: fix reading mnc-pickups
596    
597    checkpoint58t_post
598    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
599    o pkg/mdsio:
600     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
601       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
602       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
603     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
604     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
605       either MDS_READ_FIELD or MDS_WRITE_FIELD )
606     - new S/R (to replace MDSWRITEMETA), which allows to write more
607       informations (variable names, time ...) to meta files.
608     - modify rdmds.m to give back the meta file content.
609    o pkg/diagnostics: change vertical interpolation to be safer, and more
610       flexible (define p-levels to interpolate to in data.diagnostics);
611      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
612       diagnostic pointer.
613    o pkg/seaice: more cleaning up of seaice_growth, added many comments
614    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
615    o fix multi-category seaice:
616     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
617       SEAICE_MULTICATEGORY
618     - fix short wave heat flux
619    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
620       and allow to use EVP solver. Change forward lab_sea: test both EVP
621       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
622    o Initial check-in of lab_sea adjoint
623      (very similar to natl_box_adjoint/code_seaice)
624      * used C-grid and EVP solver
625      * used KPP, GM/Redi
626      * uses inAdExact=.TRUE.
627      * gradient checks fail for both ADM and TLM
628        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
629        f.d. gradients actually seem more problematic than ADM, TLM gradients;
630        issue is related to forward mismatch between g77 an ifort
631    o pkg/seaice: overhaul of thermodynamics
632     - growth.F and groatb.F are replaced by new routine seaice_growth.F
633     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
634     - move a few global fields out of SEAICE.h into seaice_growth.F and
635       make them 2D (FICE/QNETO/ ...)
636     - remove FO (it is the same as QNETO)
637     - introduce a few local fields to avoid modifying external fields such
638       as atemp, etc.
639    
640    checkpoint58s_post
641    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
642      changed exf_set_gen.F so that
643        genperiod=0 means input file is one time-constant field and
644        genperiod=-12 means input file contains 12 monthly means
645    o CG2D: use pre-computed solver main-diagonal (stored in common block);
646      this affects truncation error ; generate new output file for exp. which
647      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
648        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
649        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
650        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
651        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
652        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
653    o start implementation of deep-atmosphere and anelastic formulation
654    o verification: remove 2nd copy of input files and use script "prepare_run"
655      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
656    o mom_common/vecinv/fluxform: fix a few initialisation isssues
657    o profiles: fix for multithreaded case
658    
659    o diagnostics: rename few diags:
660      s/'PRESSURE'/'RCENTER '/g
661      s/'TICE    '/'oceFreez'/g
662      s/'TAUX    '/'oceTAUX '/g
663      s/'TAUY    '/'oceTAUY '/g
664      s/'SWFLUX  '/'oceQsw  '/g
665      s/DIFx/DFxE/g
666      s/DIFy/DFyE/g
667      and add few ocean-forcing diagnostics:
668      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
669    o modifications to pkg/seaice/growth.F and budget.F, which change results of
670      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
671      as actual snow thickness.  It now refers everywhere to effective snow
672      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
673    
674    checkpoint58r_post
675    o modifications to pkg/seaice/growth.F, which change results of
676      lab_sea experiment: fixes pertain to melting snow over open water, to
677      masking EVAP under sea ice, and to using the correct AREA variable for
678      computations of EVAP, PRECIP, HSNOW, and GHEFF
679    o add ability to read bathy, salt, and theta using MNC (off by def)
680    o add flooding algorithm and advection of HSNOW for pkg/seaice;
681      both are turned off by default and do no change any results
682    o seaice advection with pkg/thsice: a step toward the use of non-linear
683      advection scheme, but #ifdef or commented out for now (requires more EXCH).
684    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
685      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
686      in natl_box (affects results @ truncation level: update output.txt)
687    o multi-threading and IO:
688      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
689      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
690        (needed to work with SingleCpuIO): tested in all verif. exp.
691    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
692      affects the results (but none of the verification test uses this scheme).
693    o Adding some pkg/diagnostics capability to pkg/seaice
694      (will certainly be subject to changes)
695    o ctrl: adding new control variables:
696      lwflux, lwdown, evap, snowprecip, apressure, runoff
697    
698    checkpoint58q_post
699    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
700      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
701      high_res_cube configuration by 4% on Columbia.
702    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
703      add (in global_with_exf/code) a version of EXF_INTERP_READ without
704      dynamical allocation (seems to work in multi-threaded).
705    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
706      single CPU io) so that TAF does not have to see EESUPPORT.h
707    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
708    
709    checkpoint58p_post
710    o obcs: stop if obcs is used with useCDscheme = .true.
711    o shelfice:
712     - fix a sign error so that no slip at shelfice interface works
713     - remove stop for combination non-hydrostatic code and shelfice. That does
714       not mean, that the results are correct, but at least they are numerically
715       stable
716    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
717    o added adjoint exch routined for all exch*3d* routines
718      and updated flow directives
719    
720    checkpoint58o_post
721    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
722      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
723    o change controling S/R for writing pickup file (new S/R do_write_pickup)
724      and clean-up reading/writing of pickup files.
725    o fix local version of read/write pickup (NH part) in rotating_tank/code
726    o simplify EXCH interface:
727     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
728     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
729    o added the regrid package
730    o shelfice:
731     - add a simple boundary layer scheme to reduce noise
732     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
733    
734    checkpoint58n_post
735    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
736       local variable (not in common block).
737    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
738      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
739      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
740        to work with SingleCpuIO.
741    o add "_d 0" to real constant of pkg/cfc subroutines ;
742       update exp. cfc_exemple & tutorial_cfc_offline output files.
743    o multi-threading and IO:
744      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
745        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
746      - barrier before and after reading.
747      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
748      - avoid using MDS_WRITELOCAL for LAND pkg output.
749      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
750        common-block variables ; Allows multi-threading with master-thread IO.
751    o change default MAX_NO_THREADS from 32 to 4 ;
752      and stop cleanly when MAX_NO_THREADS is too small.
753    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
754    
755    checkpoint58m_post
756    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
757       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
758    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
759       keep global_ocean.90x40x15 (for AD testing) with former secondary test
760       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
761    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
762        add MITgcm_tutorials (= code + all the tutorials)
763    o ecco, option to compute cost for total ssh (mean+anom)
764    o consistent with addition of ptracer and ssh in pkg/profiles
765    o profiles: adding ptracer and ssh
766    o testreport: change multi-test output-file name
767      (from output.txt.{name} to output.{name}.txt)
768    o profiles: now ok for mutli-tiles case
769    o seaice: add 4 parameters for different advection schemes for area,
770      (effective) seaice thickness, enthalphy, and snow height. Their default
771      is the standard parameter SEAICEadvScheme
772    o calc_gw:
773     - add cosFacU in zonal viscous flux (harmonic.visc.).
774     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
775       of tutorial_plume_on_slope.
776    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
777    o calc_gw: true flux-form, account for horizontal grid spacing.
778      update rotating_tank results, but not plume_on_slope (affected at
779      truncation level, 11 digits).
780    
781    checkpoint58l_post
782    o calc_gw:
783     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
784     - remove side-drag for now (need to fix it); update plume_on_slope results.
785     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
786    o commit code to make SST/SSS weights spatially variable
787      (based on either variable in-situ or variable initial T/S weights)
788    o pkg/ecco:
789      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
790        now based on horizontally varying weights wthetaLev, wsaltLev
791      * cost_averagesflags now returns year indices in addition to day, month
792      * sflux balance is performed on annual basis
793        (sflxumm, sfluxmm2, bal_sfluxmm)
794      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
795        including separate counting and multipliers
796    o pkg/rbcs
797      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
798    
799    checkpoint58k_post
800    o testreport:
801     - always build in dir. "build" (if not there, mkdir build instead of building
802       & running in input)
803     - run in dir run (if it exists), in build otherwise.
804     - call prepare_run (if input/prepare_run exists)
805     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
806    o pkg/exf modifications to interpolation and rotation routines for more
807       reasonable treatment of North Pole singularity: for tracers North Pole
808       value is set to northernmost zonal-mean value, for zonal velocity it is
809       set to zero, and for meridional velocity it is set to northernmost value.
810    o pkg/exf/exf_check_range.F
811     - add tile index to diagnostics and move stop statement to the very
812       end of the routine.
813    o pkg/diagnostics: (diagnostics_main_init.F)
814      define title of isomorphic variables according to the current config.
815    o pkg/thsice with pkg/seaice dynamics:
816    - fix domain of computation (interior only, required for exf) and do exchanges
817    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
818    o towards a standard way of dealing with multi-threading in MONITOR
819      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
820    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
821       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
822    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
823    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
824    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
825       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
826    o tracer advection:
827     - clean-up and simplify calc_common_factors.F
828     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
829       advection subroutine (but still not used within DST advection S/R)
830    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
831    
832    checkpoint58j_post
833    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
834      from file (collects calls previously in FORWARD_STEP)
835    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
836    o adjoint store dir. adjusted accordingly
837    o genmake2
838      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
839    
840    checkpoint58i_post
841    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
842      on wind stress (SEAICEstressFactor defaults to 1.)
843    o Total number of Timers is finite (<=40): comment out 2 non-essential one
844      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
845    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
846      on CS-grid: no longer loosing mass.
847    o exf & curvilinear-grid: no longer modify longitude xC & xG.
848    o pkg/ggl90: fix sloppy output and fix a bug
849    o pkg/seaice: added SEAICEuseEVPpickup parameter
850      - Set to false in order to start EVP solver with
851        non-EVP pickup files when using SEAICEuseEVP
852      - fix sign error in diffusion in seaice_calc_rhs
853    
854    checkpoint58h_post
855    * Modifications for bottom topography control
856      o replace hFacC by _hFacC at various places
857      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
858      o add non-self-adjoint cg2d_nsa
859      o update autodiff support routines
860      o re-initialise hfac after ctrl_depth_ini
861      o works for 5x5 box, doesnt work for global_ocean.90x40x15
862    * Adding verification for 5x5 box (4-layer) bottom topography control
863    
864    checkpoint58g_post
865    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
866       used for mean seasonal cycle, mean diurnal cycle); add an example
867       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
868    o pkg/ggl90:
869      - add parameter (minimum surface kinetic energy)
870      - fix bug (avoiding division by zero)
871    o couple pkg/thsice to pkg/seaice:
872      - modify advection in seaice to accomodate new scalar fields to be advected
873      - only muliDimAdection scheme work with seaice/thsice
874      - mapping of thsice-variables to seaice-variables, back and forth
875      - does not break the verification experiments, but does not give the
876        desired results either
877    o pkg/seaice
878      - make (default) second order advection a bit less confusing?
879    
880    checkpoint58f_post
881    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
882      to pkg/seaice):
883      - new routines thsice_map_exf and thsice_get_exf provide the interface
884      - add an additional formal parameter to thsice_solve4temp
885    o pkg/exf:
886      - add new fields wspeed, snowprecip (to be able to couple to thsice)
887      - correct Stefan-Boltzmann constant
888      - new parameter for longwave surface emittance
889      - separate some stuff from exf_bulkformulae into new routines  
890        exf_radiation, exf_wind
891      - add new parameters and constants: longwave emissivity for ocean, ice
892        and snow, evaporation parameters over ice
893      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
894        either wind from stress or stress from wind
895    o pkg/thSIce:
896    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
897    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
898       and THSICE_CALC_THICKN
899    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
900    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
901      to make debugging easier.
902    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
903    o pkg/bulk_force:
904      - clean-up comments and parameters ;
905      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
906    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
907      generate new output for test-experiment: aim.5l_cs.thSI
908    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
909      testreport accordingly
910    
911    checkpoint58e_post
912    o SEAICE_CGRID adjoint done
913    o R_STAR adjoint implemented.
914      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
915      * need to sort out init. of h0facc, etc.
916    o Make pkg/profile fully independent of ecco,cost, etc. stuff
917      to be able to use it in pure forward.
918    
919    checkpoint58d_post
920    o upgrade simple test-experiment to tutorial example:
921     step.1: duplicate the experiment and (step.2) will remove the old copy.
922      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
923      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
924      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
925      tutorial_global_oce_biogeo    <- copy of dic_example
926      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
927      tutorial_plume_on_slope       <- copy of plume_on_slope
928      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
929      tutorial_global_oce_optim     <- empty for now (David ?)
930      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
931     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
932    o correct a sign problem in cost_scat.F
933    o obcs and ptracers: fix boundary conditions for advections schemes
934      with larger stencil
935    o thsice adjoint: start
936    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
937      completeness
938    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
939      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
940    o ptracers adjoint:
941      * avoid extensive recomputatations
942      * fix missing re-init. of gptr (missed by TAF)
943    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
944      me to turn off the excessive output to STDOUT that this package produces
945    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
946      and add those terms in Vector-Invariant formulation.
947    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
948      if the control period (xx_hfluxperiod etc) is 0
949    o in profiles pkg, clean routines and fix details
950    o in ecco pkg, reading ssh data:
951      fix problem in case the model does not start at iter0=0
952    o fix mnc-pickup/restart for ptracers
953    o new package prifiles:
954      code to compute profile-based cost by Gael Forget
955      (modifs in ecco, ctrl, autodiff)
956    o Benign bug fix in initialization (spotted by M. Mazloff) of
957      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
958    
959    checkpoint58c_post
960    o adjoint: finish NLFS adjoint and provide reference output in
961      verification/global_ocean.90x40x15/results_ad_nlfs
962    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
963      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
964      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
965      with SEAICE_CGRID defined.
966    o move calendarDumps from "data" to "data.cal" and clean-up the code
967      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
968    o add useEXF & useCAL flags (for now, set in hard-coded way)
969    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
970      (were missing in NH mode, and wrong in quasihydrostatic mode).
971      waiting for Chris updated version of calc_gw to add those CALLs.
972    o fix bug in quasihydrostatic S/R ;
973      add a test for this option: global_ocean.90x40x15.qshyd
974    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
975      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
976    o add on/off flag useOffLine for package OFFLINE
977    o seaice:
978      - modify advection so that it works also on the C-grid
979      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
980        problem in multi-tile runs with C-grid
981      - add flags for clipping ice velocities and/or masking solver forcing
982      - fix drag (ocean on ice) formulation and a bug that caused noise in the
983        C-grid solver
984      - added a few comments to seaice_diffusion.F
985      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
986        are now exclusive)
987      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
988        required re-ordering the code a little:
989       + make DAIRN global variable (defined in SEAICE)
990       + move computation of the viscosities eta and zeta into a new separate
991         routine (because I need to recompute them in seaice_ocean_stress.F)
992    
993    checkpoint58b_post
994    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
995      update output.txt of exp. aim.5l_cs.thSI
996    o various mnc cleanups and improvements:
997      + shrink lookup tables by factor of ~4
998      + better error reporting when running out of lookup space
999      + able to handle longer path/file names (up to 500 chars)
1000    o adjoint:
1001      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1002      - TBD: "hidden" mom_vecinv recomp. in dynamics
1003    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1004     (allow to differentiate between forcing components using new integer flags:
1005      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1006     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1007    o ecco
1008      - enable trend removal from SSH anomaly obs.
1009    o adjoint
1010      - a fix for PmEpR when #undef EXACT_CONSERV
1011      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1012      - try to fix "hidden" recomp. in forward_step for NLFS
1013        (NLFS seems broken sometimes after I checked it in)
1014    o seaice:
1015     - add c-grid version of the dynamic solver:
1016       + three new routines that are the c-grid substitute lsr, dynsolver
1017         and ostres
1018       + put a few fields that were local to dynsolver into global common
1019         blocks, so that I can move the computation of stresses etc into
1020         seaice_lsr (saves coding but may break the adjoint).
1021     - replace more hardwired parameters by runtime parameters
1022     - add ice masks that mask the rhs of the implicit solvers where there
1023       is no ice (commented out in seaice_dynsolver, because i am not sure
1024       if this works properly), eventually this should replace the clipping
1025       of ice velocities in seaice_dynsolver to +/-40cm/s.
1026    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1027      include it only where its needed
1028    o move balancing of fluxes before the call of external_forcing_surf
1029    o seaice:
1030      - correct units of turning angles (now they are really in degrees)
1031      - move computation of GWATX/Y out of main routine into dynsolver
1032      - initialize GWATX/Y in seaice_init
1033    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1034      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1035    o seaice: add runtime flags for turning angles (default to zero)
1036    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1037      and trend from exf forcing and ctrl control adjustments
1038    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1039      (since checkpoint57x_post)
1040    o change the default rotation period to 86164.s = the Earth rotation
1041    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1042      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1043    o seaice advection: add code for choosing between the default (2nd order
1044      central differences) and multiDim advection schemes provided by
1045      pkg/generic_advdiff
1046    o seaice:
1047      - removed all references to SEAICE_GRID.h fields from
1048        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1049        (cubed-sphere configuration will change a little)
1050      - grid computations in seaice_init are obsolete now.
1051      - cleaned up code a little so that is easier to read (hopefully).
1052      - added new (better?) discretizations of default advection and diffusion
1053        (turn on with SEAICEuseFluxForm)
1054      - replace 1 in 3d global fields by kSurface in growth.F
1055      
1056    checkpoint58a_post
1057    o seaice:
1058      - bug fix in advect.F
1059    o shelfice:
1060      - separate shelfice load anomaly from pload (breaks with time
1061        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1062        Its default is 0., but it may be computed more cleverly from (unknown)
1063        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1064        done offline. A good approximation of the pressure load anomaly is
1065        necessary to avoid large initial adjustment processes underneath
1066        deep-reaching shelfice.
1067      - small fix in ISOMIP shelfice_thermodynamics
1068      - add more sophisticated thermodynamics of Hellmer (1989), this is
1069        now the default
1070      - give a few constants more intuitive names
1071    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1072      if bulk formulae are used in long integration (especially EmPmR). Turn
1073      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1074      if balancePrintMean, the imbalance that is substracted is printed to
1075      STDOUT.
1076    o fix bug (typo) in obcs_apply_eta.F
1077    o add a new package shelfice which enables us to model the circulation
1078      underneath shelf-ice with draughts of hundreds of meters.
1079     - works
1080     - to do: + include improved thermodynamics
1081              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1082                instead of new field kTopC
1083              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1084                instead of new field R_shelfIce and new code in ini_depth.F
1085                and ini_mask_etc.F?
1086              + adjust vertical mixing schemes?
1087    o seaice pkg:
1088     - add a cpp-flag to include a simple formula for a salinity dependent
1089       freezing point of sea water at the surface
1090     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1091       meridional stresses are now different (and hopefully correct)
1092    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1093       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1094       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1095    o pkg/diagnostics: add options and parameters for regional-statistics
1096       diagnostics ; define regions by reading a region-mask from a file
1097       (might add other options later)
1098    o pkg/bulk_force:
1099     - add option and parameters to use AIM surface-flux formulae.
1100     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1101       others forcing fields (defined in PARM05, parameter file "data") are loaded
1102       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1103     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1104     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1105     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1106       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1107     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
