4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/ggl90: a few modifications:
8     - fix bottom boundary condition, and interpolation of KappaE
9       near top and bottom
10     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
11     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
12     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
13    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
14      (maintain temporary backward compatibility, until next checkpoint)
15    
16    checkpoint61h
17    o pkg/diagnostics with "periodic averaging diagnostics":
18      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
19    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
20    o pkg/obcs: fix loop ranges for balancing code
21    o pkg/flt:
22     - improve criteria for finding which tile owns a float.
23     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
24    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
25      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
26      with ocean biogeo)
27    o pkg/flt:
28     - do some cleaning and fix the restart ;
29     - add output.txt in flt_example/results to get this pkg tested.
30    o genmake2: add an EXTENDED_SRC option and flag.
31       for now, cannot be turned on on command line (only through genmake_local)
32    o pkg/mdsio: read/write vector:
33     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
34     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
35       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
36     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
37      (drop to 4 digits matching for grad). But this test does not look very
38      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
39    
40    checkpoint61g
41    o pkg/flt:
42      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
43       + make OPTIONS file more standard.
44      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
45      - fix _BYTESWAPIO CPP-Flag
46      - standard reading of file-parameter "data.flt"
47      - fix argument list of S/R FLT_RESTART
48      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
49    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
50    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
51      a still unfixed compiler/optimization bug
52    
53    checkpoint61f
54    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
55      update results of global_ocean.cs32x15.icedyn test.
56    o move getcon.F from model/src to pkg/fizhi.
57    o pkg/exf: add parameter for extrapolation of temp up to the surface
58       and option to prevent negative evap (in bulk_largeyeager04 only).
59    o Prather Advection scheme: fix tracer conservation for divergent flow
60      (e.g., when using NonLin Free-Surface).
61    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
62    o gmredi (Visbeck-variable-K):
63     - add more parameters to Visbeck-variable-K.
64     - use a 5 points average for dSigmaR in Visbeck-K calculation
65       (more "homogenous": same stencil and same weights as in dSigmaH)
66     - update output of ideal_2D_oce experiment.
67    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
68      (#undef REAL4_IS_SLOW)
69     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
70       coordinate variable
71     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
72       (surface forcing fields), removes some of the functionality
73     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
74     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
75       probably not all: copy _RS surface flux fields to RL field before
76       calling DIAGNOSTICS_FILL
77     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
78       real*4 (CALL EXCH_*_RS) versions.
79     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
80       (generate new output).
81    
82    checkpoint61e
83    o gmredi (Visbeck-variable-K):
84      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
85      - change computation of Visbeck-K where Slope > Smax :        
86        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
87        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
88    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
89      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
90    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
91    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
92      does not become too large (to avoid precision problems in implicit-diffusion
93      solver); update ideal_2D_oce output.
94    o pkg ggl90:
95      - in ggl90_cal.F: compute only one set of visc/diff, used to
96        step forward TKE/T/S/momentum
97      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
98        have Prandlt =1)
99    o gmredi (fm07):
100      - add lower limit on Transition layer thickness + lower limit on 1/lambda
101      - allow to set few more params from data.gmredi
102    o pkg ggl90:
103          - add missing sqrt(2) factor in computation of mixing length
104            scale in ggl90_calc.F
105            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
106    
107    checkpoint61d
108    o adjoint modifs
109      - adapt to new field rhoInSitu
110      - allow to revert from StoreDynVars2D, StoreDynVars3D
111        to individual fields
112        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
113    o store 3-D (in-situ) density in commom block (DYNVARS.h)
114     - save 1 rho computation.
115     - no longer modify T & S inland when using down_slope pkg.
116    o gad_som : allow to switch to SOM advection for T & S without corresponding
117      pickup files (using new S/R: MDS_CHECK4FILE).
118    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
119      (for useSingleCpuIO to work in multi-threaded)
120    o pkg/shelfice:
121     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
122       with SHELFICEtopoFile in data.shelfice
123     - move code for reading ice shelf topography and modifying hFacC into separate
124       subroutines of the shelfice package
125     - separate initialisation of "fixed" and "variable" variables
126     - kTopC is not (yet) replaced by kSurfC, although this is possible
127    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
128    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
129      and rename:
130      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
131      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
132    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
133    
134    checkpoint61c
135    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
136      to add mass source/sink of fluid in the interior (3-D generalisation
137      of oceanic real-fresh water flux).
138    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
139    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
140    o new pkg: down_slope
141      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
142      - presently, modify T & S inland (dwnslp_calc_rho.F).
143        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
144      - implementation for ocean in P-coords not tested.
145      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
146    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
147      (to facilitate conversion of oceanic pkg to p-coordinate).
148    o change FIND_RHO to FIND_RHO_2D :
149      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
150    o new pkg: cheapaml
151    
152    checkpoint61b
153    o exch2:
154      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
155      - no longer depend on the order sequence (N,S,E,W).
156      - 3rd exchange no longer needed (tested with 24 tiles).
157      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
158      - exch_UV_A-grid readily available (but not yet tested).
159      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
160      (both are no longer needed) in exch_uv: no effect in forward run; but
161       get truncation error differences with adjoint exch.
162    o exch2:
163     - change index-bounds storage (moved from target to local tile,
164       more intuitive this way) ; rename/remove some variables.
165     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
166    
167    checkpoint61a
168    o exch2/matlab-topology-generator:
169      fix bug in index bounds for N-S internal exchange (hard to tell if this
170      had any effect on the solution).
171    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
172      is exceeded
173    o testreport: modify syntax of awk, so that it works also with
174      awk, and not only with nawk and gawk
175    
176    checkpoint61
177    o autodiff
178      Change default for TAF usage by removing argument '-nonew_arg'
179      This changes TAF subroutine argument list (ordering of active var.)
180      Omission of this flag leads to incompatibility w.r.t. TAMC
181      To restore TAMC-compatibility, need following modifs:
182      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
183      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
184      Tested TAF version is 1.9.22
185      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
186    
187    checkpoint60
188    --->>> This is the last checkpoint for which generating the adjoint
189    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
190    --->>> by default.
191    --->>> Future checkpoints will ommit this flag by default.
192    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
193    o pkg/grdchk: Add gradient check to etan0 perturbations.
194    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
195    o pkg/autodiff: more flexibility in zeroadj.
196      model/src: modifying do_oceanic_phys.F accordingly.
197    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
198    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
199      special setup of gmredi for which the adjoint is stable
200      enough for parameter optimization.
201    o bridging the gap between eddy stress and GM.
202      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
203          along with a change in CPP option (now ALLOW_EDDYPSI).
204      -> when using GM w/ GM_AdvForm:
205          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
206          is applied either in the tracer Eq. or in momentum Eq.
207          depending on data.gmredi (intro. GM_InMomAsStress).
208      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
209      The key modifications are in model/src/taueddy_external_forcing.F
210      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
211    
212    checkpoint59r
213    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
214      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
215      fix option to read coriolis(@ cell-corner) from files with CS-grid.
216    o pkg/mnc: add some attributes to standard 1D-coordinate variables
217    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
218      mass points, when using mnc for output
219      - add runtime parameter (missing_value, missing_value_int) to override
220        default (which is the value of getcon('UNDEF'))
221    o pkg/mnc: prepare mnc for the actual use of missing values with the
222      diagnostics package: small fix in mnc_cw_readwrite.template and more
223      initialisation of never used fields
224      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
225      versions
226    o pkg/thsice/thsice_ini_vars.F added default initial values so that
227      thermodynamics sea ice solver does not blow up when some initial fields
228      are missing.
229    o move from external_forcing_surf.F to ini_forcing.F
230      the p-coord. hack consisting in using pLoad to set phi0surf ;
231      update output of tutorial_global_oce_in_p (affected @ truncation level).
232    o Freshen up a bit hs94.1x64x5, notably:
233      remove rotationPeriod and tRef=5*0. (adjoint only), and add
234      exactConserv=.TRUE.
235    o pkg/generic_advdiff:
236      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
237      applies to files where Temperature & Salinity 2nd Order moments are used.
238    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
239      this uses a dynamically allocated internal state data structure
240      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
241      and requires a fortran 90 compiler
242    
243    checkpoint59q
244    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
245       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
246    o Refresh tutorial_global_oce_biogeo, notably:
247      - change bathymetry (put back seamounts in ACC, use hFacs)
248      - change EOS (POLY3 --> JMD95Z)
249      - use Bryan-Lewis vertical diffusivity
250      - use multidimensional advection
251      - remove old virtual virtual in dic pkg, now done through ptracer pkg
252      - change a couple of parameters in dic pkg
253    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
254    o pkg/obcs: change default to OBCSfixTopo = .true.,
255      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
256      - replace "debugMode" with "debugLevel .GE. debLevB"
257    o implementation of TAF directives for gchem,cfc,dic
258    o remove "exp5" (replaced by tutorial_deep_convection).
259    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
260      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
261      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
262      --> changes results in exp4, seaice_obcs
263    o tutorial_deep_convection :
264      update the set-up and increase resolution and domain size ; start
265      from pseudo initial conditions = output at t=120mn in order to see
266      something happening when running testreport.
267    o pkg/seaice: add os7mp as an advection scheme
268                  add check for advection schemes
269                  add a flag for restoring T and S underneath sea ice
270    o pkg/my82: add netcdf-support and diagnostics
271    o thsice pkg:
272      - Now hsMax limits snow height by turning it into ice following
273        flooding scheme (and now conserving energy)
274      - Slight rewriting of the formula in thsice_calc_thick.F
275      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
276      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
277    
278    checkpoint59p
279    o gchem / dic / cfc :
280      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
281      - add new parameter files: "data.dic" & "data.cfc" ;
282      - various re-arrangement in initialisation & header file ;
283      - fix tutorial_global_oce_biogeo for multi-threaded test.
284    o pkg/dic: test for "pickup_dic" file when restarting ;
285      if no pickup-file, can restart with a re-initialised pH (same as it did
286      before) providing pickupStrictlyMatch is set to False.
287    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
288      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
289    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
290      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
291    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
292     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
293       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
294    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
295       scheme to use for vorticty-term ;
296     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
297       (with default selectVortScheme, return to original discretisation)
298     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
299    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
300    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
301      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
302      also fix diagnostics VISCAHW & VISCA4W.
303    
304    checkpoint59o
305    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
306    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
307      move a few statemens out the main loop into separate loops
308    o pkg/shelfice:
309      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
310        (kg/m^2/s), does not break tests, because in verification/isomip,
311        rhoConstFresh=rhoConst (by accident)
312      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
313      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
314        new file model/src/seawater.F, so that they are available for all pkgs.
315      - convert potential temperature into in-situ temperature. This changes the
316        isomip tests => update tests
317    o add a flag writePickupAtEnd (default=true) to be able to suppress
318      writing a pickup at the last timestep
319    o tools/mpack-1.6 :
320      - disable automake (not working) and autoconf (not needed).
321      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
322        also cleaner with much less compilation warnings.
323    o pkg/profiles:
324      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
325      (for "less than 32 characters name" compiler requirement)
326    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
327      conditions that have a different sampling frequency than S/T/U/V obcs
328    o pkg/diagnostics (stats-diags):
329      - fix global Min/Max in case 1 processor get only empty tiles
330    o genmake2: replace (4 times)
331         make genmake_tc_1.o >> genmake_warnings 2>&1
332      with
333         COMM="$CC $CFLAGS -c genmake_tc_1.c"
334         echo $COMM >> genmake_warnings
335         $COMM >> genmake_warnings 2>&1
336      to make genmake2 always see the value of CC as specified in the optfile.
337    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
338      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
339      - modify verification advect_cs test to test SOM-advection on CS-grid.
340    o pkg/ctrl:
341      - Rewrite of ctrl_map_ini_ecco.F,
342        introducing a generic routine (ctrl_map_ini_gen.F).
343      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
344    
345    checkpoint59n
346    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
347      number in dedicate array "hdiag":
348      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
349        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
350      - many small changes (integer format) for large number of diagnostics
351      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
352        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
353    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
354      usingSphericalGrid, this allows to define the rotated grid coordinates
355      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
356      geographical coordinates according to the inverse of the rotation defined
357      by the Euler angles, so that Coriolis parameter and online-interpolation by
358      exf works with the geographical coordinates on XC/YC/XG/YG.
359      Naturally, this feature does not work with all packages, so some
360      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
361      profiles), because there the coordinates are assumed to be regular
362      spherical grid coordinates.
363    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
364      - introduce isopycnal diffusion coefficient control.
365    o tools/adjoint_options:
366      - additional control vector components.
367    o pkg/mnc: have mnc create marginally meaning full coordinate variables
368      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
369    o pkg/mypackage:
370      - add example of read/write pickup for state-var ;
371      - add entry points to the main code for state-vars diags & write-pickup.
372    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
373      transitions for useExfYearlyFields
374      - add new subroutine that determines the file to read from for
375        use*YearlyFields = .TRUE. and .FALSE.
376      - add a verification experiment to global_with_exf that tests
377        useExfYearlyFields with USE_EXF_INTERPOLATION defined
378    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
379      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
380      subroutines (which could be generated from a template, because they are
381      almost identical), for now they are included in obcs_prescribe_read.F for
382      simplicity
383    o pkg/exf:
384      - add a little more diagnostic to exf_interp_read (in analogy to
385        mds_read_field, can be turned off with debugLevel < debugLevA=1)
386      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
387        ugly but fast by unrolling short inner loops, inserting a unroll=8
388        directive in routine lagran, and splitting a loop and making do while the
389        outermost loop (the latter requires the intoduction of index arrays)
390    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
391    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
392      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
393    o verification/seaice_obcs: updated for restart test and latest options
394    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
395      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
396      for now this is only available for the C-grid code and also within
397      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
398    
399    checkpoint59m
400    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
401      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
402    o gad_som : fix flux output (& diagnostics) to have same units as other  
403      advection scheme fluxes (was previously multiplied by deltaT).  
404    o added verification/seaice_obcs both to test seaice open boundaries
405      and to provide an example matlab scrpt for generating them
406    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
407    o pkg/salt_plume: clean up salt_plume_frac.F to
408      remove redundancy in PlumeMethod 1 and 4
409    o pkg/kpp: added saltplume diagnostics
410    o pkg/obcs and pkg/seaice:
411      - do not set uice and vice to zero when OB*icefile are unspecified
412      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
413      - moved seaice tracer obcs after call to seaice_growth
414    o pkg/salt_plume: added various options for salt plume depth
415      criterion and for vertical distribution of the salt
416    
417    checkpoint59l
418    o pkg/ptracers: new version of ptracers pickup:
419      read meta file and write only fields which are needed to restart.
420      ( same logic as main pickup file ; also using pickupStrictlyMatch )
421    o pkg/seaice:
422      - add timescale for melting due to warm mixed layer as a means of
423        setting SEAICE_availHeatFrac more conveniently
424      - add a CPP-flag/runtime parameter check for flooding algorithm
425      - reformulated availHeat in seaice_growth.F to be independent of AREA
426    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
427      unit changes
428    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
429    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
430      SX vector computer.
431    o pkg/seaice:
432      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
433        seaice forcing fields can now be read only through pkg/exf
434      - removed some unused halos
435    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
436    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
437      or U/VICE from U/VWIND before computing U/VSTRESS
438    
439    checkpoint59k
440    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
441      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
442    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
443      all experiments pass when compile with un-initialised var. checking option.
444    o added pkg/salt_plume
445    o script to test restart (for now, in MITgcm_contrib/jmc_script)
446    o pkg/seaice: new read/write pickup version.
447      read meta file and write only fields which are needed to restart.
448      ( same logic as main pickup file ; also using pickupStrictlyMatch )
449    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
450    o lab_sea.hb87: modify the domain & update output.hb87.txt :
451      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
452      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
453      process. Fixed here by closing the domain at the Northern boundary.
454    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
455    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
456      a set of consecutive levels in/from a 3-D array.
457    o pkg/ptracers:
458      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
459      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
460    
461    checkpoint59j
462    o in pkgs: dic, obcs, offline, rbcs:
463      standard way to compute coeff. for time interpolation between 2 time reccords
464      which retains full precision (& make results less dependent on compiler).
465      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
466    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
467      packages instead of reading ice cover and wind speed separately
468    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
469     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
470      to allow to compile customized code before the update)
471    o cleaning-up:
472      - fix CPP instruction syntax in pkg/obcs
473      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
474        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
475      - fix some threads issue in IO parts.
476    o pkg/dic:
477      - add tons of "_d 0" (--> much better testreports !)
478       and then update outputs of tutorial_global_oce_biogeo
479    o pkg/mom_fluxform:
480      add a special version of momentum advection intended to conserve momentum
481      next to a bathymetry step or a coastline edge. (default = off = #undef)
482    o new read/write pickup version:
483      - for now, only implemented for main (mdsio) pickup file.
484      - write out only what is needed to restart; merge pickup_nh , pickup_ph
485        and main pickup together.
486      - read meta file; read only what is needed to restart; stop if a field
487        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
488        if it make sense (even if the restart is not perfect).
489      - if no meta file, assume that pickup to read corresponds exactly to
490        a pickup that would currently be written.
491      - read pickup written in the old format (until checkpoint59i) if it
492        recognizes an old meta file (no field-list).
493      - add a meta file in exp. which starts from a pickup: 2 cases:
494        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
495         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
496        b) a meta file describing the content of the associated pickup file
497         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
498    o pkg/mdsio & pkg/rw:
499      - new routine to read a meta file ; new set of routine to read
500        Multiple-fields file (with meta file).
501    o added open boundary conditions capability for seaice
502        HSNOW, HSALT, UICE, and VICE
503    
504    checkpoint59i
505    o adjoint:
506      * fix multiDimAdvection adjoint
507        (partial recomputation problem by TAF for fVerT(:,:,kDown)
508        and comlev1 size definition (maxpass vs. max. number of tracers)
509      * verification/global_ocean.90x45x15 adjoint now tests
510        NLFS and multiDimAdvection using DST3 (=30)
511      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
512    o pkg/kpp: add "_d 0" to real constant (if missing);
513      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
514      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
515    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
516      for internal parameters related to restart process (formerly from PARAMS.h)
517      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
518    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
519      as argument. (only atm2d & obcs write_pickup have not yet been updated)
520    o pkg/monitor:
521      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
522      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
523      - account for deep Atmosphere factor and density factor (anelastic)
524    o added open boundary conditions capability for seaice HEFF and AREA
525    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
526      thermodynamics
527      - requires a little reorganization, which affects the testreport results
528        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
529        so that now the conservative form is tested
530      - add a few comments
531    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
532    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
533    o add new diagnostics to seaice: advective, diffusive fluxes (only for
534      multidim-advection, for scheme 2 they are not filled) and transports,
535      thermodynamic growth rates
536    o change units of EmPmR (inside the code, + within coupling interface)
537      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
538      Affects results @ truncation level (cg2d match) and update output of
539       experiments: lab_sea(6), global_ocean.90x40x15(10),
540      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
541      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
542      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
543      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
544    
545    checkpoint59h
546    o pkg/exf:
547      - improve vectorization by moving if-statement out of loops in
548        exf_mapfields, exf_radiation
549      - exf_bulkformulae.F: introduce 2D fields and vectorize code
550    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
551    o testreport:
552      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
553        monitor & update offline_exf_seaice exp. output.
554      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
555    o pkg/seaice:
556      - bug fix in the evp solver: boundary conditions were affected be
557        masking of zMax/zMin (changes results)
558      - minor bug fix in boundary conditions in seaice_calc_strainrates
559        (changes results for no_slip)
560      - seaice_lsr.F: make interpolation of eta dependent on boundaries
561      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
562      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
563        stress formulation and no-slip boundary conditions
564    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
565      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
566    o pkg/seaice: a first HSALT time stepping equation has been checked in
567    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
568      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
569      without requiring DO-IF statements
570    o pkg/thsice:
571      use continuous power-law function for partition of energy between lateral
572      melting/freezing and thinning/thickening ; old code using step function
573      still available with #undef THSICE_FRACEN_POWERLAW
574      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
575    o testreport: change AD testing : check against results/output_adm.txt
576      using same scripts as for forward test.
577    
578    checkpoint59g
579    o adjoint testing: in preparation for changing testreport:
580      - output format: cost and grad written on separated lines
581      - ad output results in directory "results" (instead of "results_ad")
582    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
583    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
584    o pkg/ecco: allow user defined cost function contributions
585    o testreport:
586      Allow to choose (per experiment) the list of tested output variables
587       and the main variable (used to issue a pass/FAIL ) ;
588      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
589      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
590      Also modify printing of summary:
591       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
592       b) echo the list of tested variables in the individual summary.txt of
593          each experiment.
594    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
595      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
596      (but still depend on the tile decompostion of the domain).
597    o pkg/seaice: change a discretization detail to make the B-grid code
598      "more symmetric". This change is likely to remove all "ridges/leads" that
599      where quasi-aligned with the grid in B-grid solutions. It may also be
600      the solution to the stress coupling issues with the B-grid.
601    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
602      remove .cvsignore from input dir. (since testreport no longer run here).
603    o pkg/thsice:
604     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
605     - fix reshaping of sea-ice just after advection:
606       melt all the ice only if ice-volume is too small.
607     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
608       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
609     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
610    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
611      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
612    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
613      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
614      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
615      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
616      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
617      -> update output.txt
618    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
619     this affects truncation error: -> update output.txt of exp:
620      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
621      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
622    
623    checkpoint59f
624    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
625    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
626      a bounded range (in forward mode)
627    o pkg/ecco, ctrl, autodiff and mom_common:
628     internal parameter controls, completements of implementations
629    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
630    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
631      (not seem any difference in testing results).
632    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
633       at face corners.
634    o pkg/generic_advdiff:
635     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
636      loop range indices for computing vertical advection tendency
637      and do the calculation in the interior only (no overlap) ;
638      for now, only implemented for SOM advection (to save CPU time).
639     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
640    o exch2 adjoint
641      First set of changes:
642      - add exch2 hand-written adjoint templates
643      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
644        This will require cleanup in pkg/autodiff/*.F
645        (changed routines currently kept separate in verif. code/)
646      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
647        that used to hide exch2 or cubed-sphere specific code
648        (commented via 'cph-exch2')
649    o pkg/seaice
650      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
651    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
652       output of global_ocean.cs32x15.thsice .
653    
654    checkpoint59e
655    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
656      for B-grid vector (not yet tested) and C-grid vector (<- only used
657      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
658    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
659      (#ifdef ALLOW_SALT_PLUME)
660    o gather_2d/scatter_2d: removed halo regions
661    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
662      scheme and the corresponding test case (under front_relax dir). For now,
663      only available with Skew-flux form and not yet tested in realistic set-up.
664      adjoint: store directives updated, but gradient checks deteriorated,
665      so maybe GM/Redi adjoint is now broken.
666    o seaice adjoint
667      * add AREA, HEFF, HSNOW as control variable
668        (should not change lab_sea results)
669      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
670    o pkg/seaice:
671      * added computation of saltFlux in seaice_growth;
672        For time being, sea ice salinity is assumed constant
673        contribution of snow flooding to freshening of sea ice is neglected.
674        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
675        defaults to 0.0 in order to maintain backward compatibility.
676        Typical values for SEAICE_salinity are 4 to 10 g/kg.
677      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
678      * added SEAICE_availHeatFrac, which specifies fraction of surface level
679        heat content used to melt or grow ice
680      * commented out cap of HICE: it helps keep ice thinner
681      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
682      * applied OBCS T/S mask to HEFFM sea ice mask
683    
684    checkpoint59d
685    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
686     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
687     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
688    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
689     and change default value of parameter "GM_Small_Number";
690     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
691       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
692       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
693    o pkg/ecco: cost function when applying pkg/smooth to controls
694    o pkg/ctrl: add forcingPrecond run time parameter
695    o pkg/seaice:
696     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
697     - fix bug in metric terms of u-equation in LSR solver (implicit part),
698       changes verification/lab_sea
699     - rearrange implicit part of u-equation in LSR solver to make it easier to
700       read, understand, and debug. This causes changes at the truncation level.
701     - fix (serious) bug in the boundary conditions (sign error in the implicit
702       part) of the LSR solver. Changes all LSR results.
703     - fixed problem with HSNOW initialization to avoid thick snow when AREA
704       is initilized with small values - does not change lab_sea results.
705     - added HsnowFile initialization capability
706    o pkg/smooth: addition to model/src and pkg/ctrl so allow
707     initialization of pkg/smooth and application to control vector
708    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
709    o dependencies: pkg/profiles requires pkg/cal
710    o pkg/profiles:
711     - added option ALLOW_PROFILES_GENERICGRID
712         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
713         that interpolation information (grid points and coefficients) is provided
714         within the netcdf input files.
715         -> sample matlab scripts can be found in MITgcm_contrib/gael
716         that allow you to prepare netcdf input files.
717     - also modified: cleaner include statements, cleaner error print statements,
718       cleaner stops when error, and more tests of the netcdf input files consistency.
719    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
720    o pkg/seaice:
721     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
722       requires a new routine: seaice_diagnostics_fill.F
723     - make sure that seaice does not move if not forced (pressure replacement
724       method, Hibler and Ip, 1995), changes results
725     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
726     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
727       It is turned off by default (=-1.), because it changes the results.
728     - make it possible to read AREA from a file, too.
729    
730    checkpoint59c
731    o add S/R and diagnostics for oceanic mixed-layer depth
732    o move GMRedi call after all vertical mixing schemes (including KPP)
733    o pkg/thsice:
734     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
735      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
736    o pkg/obcs:
737     - bug fix for balance code
738    o pkg/seaice:
739      - allow values of SEAICE_elasticParm > 1
740      - add new parameter SEAICE_evpTauRelax as an alternative
741        to SEAICE_elasticParm
742      - make lsr boundary conditions free slip (by default), changes result
743      - add code for no slip boundary conditions for lsr
744      - set minimum of zeta to zero (and not 4e8) (changes results)
745      - add a cap on AREA after advecting AREA if seaice_growth is not called
746    o change calculation of Visbeck K:
747      - no longer depend on tapering scheme; instead, compute slope (limited
748        by GM_maxSlope). this is equivalent to what was comuted before with
749        clipping or linear tappering.
750      - fix vertical averaging (wrong by 1/2 level)
751      - leave the old version (but will not be maintained) within
752        #ifdef OLD_VISBECK_CALC / #endif
753      - update output of exp. ideal_2D_oce
754    o change error catch in calc_r_star to improve vectorization
755    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
756      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
757    o adjoint:
758      Re-organized adjoint checkpointing according to Matt Mazloff
759      (but with modifs/completions/cleanups)
760      Storing is now bundled into large arrays to optimized I/O
761      (and second step in cleanup of the_main_loop)
762    
763    checkpoint59b
764    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
765      - export/import (between ocean & coupler) fields needed for ocean DIC.
766    o pkg/seaice:
767      - get rid of three more exchanges seaice_calc_viscosities (required
768        different loop boundaries in seaice_lsr and seaice_ocean_stress)
769      - bug fix in seaice_ocean_stress (update of lab_sea required)
770      - reduce loop boundaries to necessary minimum also in seaice_evp
771      - go back to the old way of computing deltaC/Z as the adjoint likes that
772        better
773    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
774      passive tracer to an Age Tracer) + update output.txt
775    o pkg/exf:
776      - implement A-grid / C-grid selection for wind-stress input files.
777      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
778      for now, in exf_bulk_largeyeager04.F only :
779      - change implementation for case where windspeed + 2. components wind-stress
780        are read-in. AND use rhoConstFresh to convert evap.
781    o pkg/seaice:
782      - use correct EXCH_UV for wind-forcing (on A-grid).
783      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
784        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
785    o pkg/exf:
786      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
787      EXF_INTERPOLATION:
788      - merge global_with_exf/code version of exf_interp_read.F
789        to the main code ;
790      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
791        reading the file ; Important: This options needs to be defined to recover
792        previous code.
793        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
794      - no longer loose real*8 precision along the way when using exf_iprec=64.
795    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
796      - change discretisation of evp-solver in order to avoid another exchange
797        (changes lab_sea) and clean up a little
798      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
799        help the adjoint (this also changes the results slightly)
800      - add a few "_d 0" where they had been missing in seaice_evp.F
801      - cleaning up: remove unused seaice_calc_rhs.F
802    o pkg/exf: some cleaning-up:
803      - change various "constants" into runtime parameters
804      - cleaned-up Large&Yeager04 routine which should eventually
805        replace exf_bulkformulae.F (changed names of S/R and CPP)
806        and merged various ALLOW_ATM_WIND options
807     only used with thsice pkg (in thsice_get_exf.F):
808      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
809        which are used when useStabilityFct_overIce=TRUE (= the default)
810      - change default values of ice & snow emissivity and scale downward LW
811        by ice & snow emissivity.
812    o pkg/thsice:
813     fix few little problems, in thsice_calc_thickn.F:
814      - growth vertically (and not laterally) if iceFrac == iceMaskMax
815      - melt only laterally if hIce < hThinIce (as the comments say)
816      and in thsice_extend.F:
817      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
818      - start to form ice as soon as the minimum ice-volume is reachable.
819     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
820      and cpl_aim+ocn
821    o pkg/kpp
822     - move computation of surface related input fields to KPP into a new
823       subroutine kpp_forcing_surf.F
824     - remove wrong (within bi,bj loops) EXCH calls.
825     - little cleaning (add argument myThid in last position, cvs header ...)
826     - for now, fix conservation problem by exchanging KPPviscAz (may not
827       be the best fix)
828    o pkg/seaice
829     - check for inconsistent evp parameter/cpp-flag combination
830     - remove leftover errIO flat for obsolete name list error handling
831    o OpenAD
832     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
833    
834    checkpoint59a
835    o pkg/seaice: some parameter clarifications and a little bit of clean up
836    o pkg/thsice: rename run-time parameters:
837       himin       -> hIceMin
838       himin0      -> hThinIce
839       hihig       -> hThickIce
840       i0          -> i0swFrac
841       transCoef   -> bMeltCoef
842       frac_energy -> fracMelting
843      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
844       with default values (for now) that do not change the results.
845      remove old version of thsice vars advection in pkg/seaice.
846    o in FFIELDS.h:
847      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
848      - make pLoad & sIceLoad always available (but still only used if
849         ATMOSPHERIC_LOADING is #define).
850    o pkg/kpp: replaced _KPP_RL with _RL
851    o bug fixes for vertical diffusivity computations when both KPP and
852        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
853        are no longer updating the vertical diffusivity array
854        (passed as argument) but are (re-) setting those arrays.
855    o pkg/seaice: fix bug in evp solver, while doing that
856      - change (improve?) discretization of stress computations for both
857        cgrid-lsr and evp solver
858      - add a new routine to compute strain rates
859      - the above changes lab_sea results
860      - add no slip conditions for evp solver (off by default), lsr-version
861        may follow
862      - fix exchange for shear at Z-points (does not change lab_sea)
863      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
864        (to force the user to pick a time step since there is not "safe" way
865        of choosing it)
866      - add principal stress diagnostics
867      - rearrange fields for evp a little to avoid having to call a: too many
868        exchanges and b: exchanges for stress trensor components which we do
869        not have.
870      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
871        of evp, complete rewrite for lsr case (latter is does not yet work
872        in all cases)
873    o pkg/kpp: add code to have mixing in shelf ice caverns
874      - add myThid to all kpp routines (long overdue)
875    
876    checkpoint59
877    o pkg/exf:
878      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
879        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
880      - move exf header files from lower_case.h to UPPER_CASE.h ;
881        add missing cvs Header & Name
882      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
883      - add namelist param. selectStressGridPosition, exf_monFreq
884      - retire many _CLIM routines, and remove data.exf_clim
885        + params moved to data.exf
886        + climsst, climsss now handled by exf_set_gen, i.e.
887          climss?period=0 refers to constant field,
888          climss?period=-12 to monthly forcing
889      - split up namelists in data.exf
890    o pkg/seaice:
891      - remove seaice_exch and seaice_exch_uv
892      - remove superfluous exchange of theta
893      - add myThid to seaice_budget_ocean/ice
894      - add new interface for atmospheric wind forcing (C-grid only)
895        + new routine
896        + two new field (taux, tauy for stress over ice)
897        + removed one global field (DAIRN) for C-grid case only
898    o pkg/thsise
899      - 2nd set of modifs for thsice adjoint in conjunction with exf
900    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
901    
902    checkpoint58y_post
903    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
904      vertical diffusivity, similar to that in MOM4; turned on using
905      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
906      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
907    o Added capability for 3D specification of background vertical diffusion
908      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
909      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
910      "data" file that contains the 3D vertical diffusivity coefficients.
911    o ice dynamics (pkg/seaice) with thsice thermodynamics:
912      - add code within pkg thsice to advect & diffuse sea-ice fields
913      similar to (and will replace) what has been added in  seaice_advdiff.F,
914      but: - conserving Mass, Heat & Salt.
915           - better when using non-linear advection scheme (not yet fully tested)
916           - can also be used in atmospheric set-up (for now, only the diffusion).
917    
918    checkpoint58x_post
919    o IO option for global-file compact format:
920      - add options when generating topology (utils/exch2/matlab-topology-generator)
921      - add I/O capability (pkg/mdsio).
922      - adapt utils/matlab/rdmds.m to read this format.
923      for now long-line format not yet supported by pkg/mdsio (& exch2).
924    o shelfice: add a few diagnostics
925    
926    checkpoint58w_post
927    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
928      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
929      (and replace horiVertRatio in NH code).
930      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
931                         and tutorial_plume_on_slope (sensitive to truncation)
932    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
933      directly to drive seaice model (C-grid only)
934    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
935     - reintroduce computation of wind from stress,
936     - compute tau (in exf_bulkformulae.F) from windstress averaged to
937       mass points to avoid tau = 0
938     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
939    o rdmnc.m: make it work with "global" files created with gluemnc
940    o rdmnc.m : some improvements in dealing with singleton dimension
941      (tested on all testreport mnc output files).
942    o genmake2: disable pkg/profiles if netcdf test fails.
943    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
944    o move call to cal_readparms up to make calendar parameters/variable available
945      to all packages
946    
947    checkpoint58v_post
948    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
949      useDynP_inEos_Zc tested.
950    o pkg/exf: changes to properly interpolate/mask/scale initial fields
951    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
952      and portions thereof.  See read_cs.txt for description and examples.
953    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
954      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
955      following the great-circle arc between those 2 points.
956    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
957      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
958    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
959     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
960     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
961     - still needs work (not working with some options ; efficiency to improve)
962       and serious testing.
963     - use this scheme for temperature & salinity in 2 advection test exp.:
964       advect_xy & advect_xz, respectively.
965    
966    checkpoint58u_post
967    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
968    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
969    o testreport: add option "-skipdir" to skip some test.
970    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
971      momentum calculation.
972    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
973    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
974      remove checkpoint.F and the_correction_step.F (no longer used);
975      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
976    o add option (linFSConserveTr) to correct for tracer source/sink due to
977      Linear Free surface
978  o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine  o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
979  o pkg/thsice: fix reading mnc-pickups  o pkg/thsice: fix reading mnc-pickups
