4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/ctrl:
8      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
9    o non-hydrostatic (calc_gw.F):
10      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
11      update output of exp. global_ocean.cs32x15.viscA4
12    o remove backward compatibility for thetaMin,phiMin
13      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
14    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
15      interpolated wind field not only for curvilineargrid=.true., but also
16      for a rotated grid (rotateGrid=.true.)
17    o pkg/exf: add capability to bypass interpolation for runoff
18      by setting yet another CPP-flag
19    o eesupp/src, B-grid exchange:
20      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
21    o autodiff
22      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
23      allows to switch to single-prec common blocks;
24      corresponding switch occurs in tamc.h, integer isbyte
25      TAF store directivs "byte" and "kind" seem equivalent;
26      Most tamc.h have been updated correspondingly.
27    
28    checkpoint61i
29    o autodiff:
30      fix autodiff_sore/_restore indices for obcs
31      (spotted by I. Hoteit, M. Mazloff)
32    o pkg/autodiff, pkg/ctrl:
33      Add flag to reduce all tapelev I/O to single-prec.
34      In data.ctrl set
35        doSinglePrecTapelev = .TRUE.
36    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
37      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
38    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
39      real fresh water flux (not yet)
40    o pkg/mdsio & rw:
41     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
42     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
43    o pkg/flt:
44     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
45       init_fixed & ini_varia.
46     - clean-up & simplify linear interpolation S/R:
47       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
48     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
49     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
50     - add vert. coordinate & horiz. indices to output files.
51     - change vertical position in initial condition, from index to depth [m].
52     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
53       (easier to get to a curvilinear grid) ; delX,delY no longer used.
54    o pkg/ggl90: a few modifications:
55     - fix bottom boundary condition, and interpolation of KappaE
56       near top and bottom
57     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
58     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
59     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
60    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
61      (maintain temporary backward compatibility, until next checkpoint)
62    
63    checkpoint61h
64    o pkg/diagnostics with "periodic averaging diagnostics":
65      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
66    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
67    o pkg/obcs: fix loop ranges for balancing code
68    o pkg/flt:
69     - improve criteria for finding which tile owns a float.
70     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
71    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
72      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
73      with ocean biogeo)
74    o pkg/flt:
75     - do some cleaning and fix the restart ;
76     - add output.txt in flt_example/results to get this pkg tested.
77    o genmake2: add an EXTENDED_SRC option and flag.
78       for now, cannot be turned on on command line (only through genmake_local)
79    o pkg/mdsio: read/write vector:
80     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
81     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
82       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
83     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
84      (drop to 4 digits matching for grad). But this test does not look very
85      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
86    
87    checkpoint61g
88    o pkg/flt:
89      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
90       + make OPTIONS file more standard.
91      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
92      - fix _BYTESWAPIO CPP-Flag
93      - standard reading of file-parameter "data.flt"
94      - fix argument list of S/R FLT_RESTART
95      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
96    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
97    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
98      a still unfixed compiler/optimization bug
99    
100    checkpoint61f
101    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
102      update results of global_ocean.cs32x15.icedyn test.
103    o move getcon.F from model/src to pkg/fizhi.
104    o pkg/exf: add parameter for extrapolation of temp up to the surface
105       and option to prevent negative evap (in bulk_largeyeager04 only).
106    o Prather Advection scheme: fix tracer conservation for divergent flow
107      (e.g., when using NonLin Free-Surface).
108    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
109    o gmredi (Visbeck-variable-K):
110     - add more parameters to Visbeck-variable-K.
111     - use a 5 points average for dSigmaR in Visbeck-K calculation
112       (more "homogenous": same stencil and same weights as in dSigmaH)
113     - update output of ideal_2D_oce experiment.
114    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
115      (#undef REAL4_IS_SLOW)
116     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
117       coordinate variable
118     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
119       (surface forcing fields), removes some of the functionality
120     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
121     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
122       probably not all: copy _RS surface flux fields to RL field before
123       calling DIAGNOSTICS_FILL
124     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
125       real*4 (CALL EXCH_*_RS) versions.
126     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
127       (generate new output).
128    
129    checkpoint61e
130    o gmredi (Visbeck-variable-K):
131      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
132      - change computation of Visbeck-K where Slope > Smax :        
133        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
134        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
135    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
136      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
137    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
138    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
139      does not become too large (to avoid precision problems in implicit-diffusion
140      solver); update ideal_2D_oce output.
141    o pkg ggl90:
142      - in ggl90_cal.F: compute only one set of visc/diff, used to
143        step forward TKE/T/S/momentum
144      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
145        have Prandlt =1)
146    o gmredi (fm07):
147      - add lower limit on Transition layer thickness + lower limit on 1/lambda
148      - allow to set few more params from data.gmredi
149    o pkg ggl90:
150          - add missing sqrt(2) factor in computation of mixing length
151            scale in ggl90_calc.F
152            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
153    
154    checkpoint61d
155    o adjoint modifs
156      - adapt to new field rhoInSitu
157      - allow to revert from StoreDynVars2D, StoreDynVars3D
158        to individual fields
159        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
160    o store 3-D (in-situ) density in commom block (DYNVARS.h)
161     - save 1 rho computation.
162     - no longer modify T & S inland when using down_slope pkg.
163    o gad_som : allow to switch to SOM advection for T & S without corresponding
164      pickup files (using new S/R: MDS_CHECK4FILE).
165    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
166      (for useSingleCpuIO to work in multi-threaded)
167    o pkg/shelfice:
168     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
169       with SHELFICEtopoFile in data.shelfice
170     - move code for reading ice shelf topography and modifying hFacC into separate
171       subroutines of the shelfice package
172     - separate initialisation of "fixed" and "variable" variables
173     - kTopC is not (yet) replaced by kSurfC, although this is possible
174    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
175    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
176      and rename:
177      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
178      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
179    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
180    
181    checkpoint61c
182    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
183      to add mass source/sink of fluid in the interior (3-D generalisation
184      of oceanic real-fresh water flux).
185    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
186    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
187    o new pkg: down_slope
188      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
189      - presently, modify T & S inland (dwnslp_calc_rho.F).
190        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
191      - implementation for ocean in P-coords not tested.
192      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
193    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
194      (to facilitate conversion of oceanic pkg to p-coordinate).
195    o change FIND_RHO to FIND_RHO_2D :
196      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
197    o new pkg: cheapaml
198    
199    checkpoint61b
200    o exch2:
201      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
202      - no longer depend on the order sequence (N,S,E,W).
203      - 3rd exchange no longer needed (tested with 24 tiles).
204      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
205      - exch_UV_A-grid readily available (but not yet tested).
206      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
207      (both are no longer needed) in exch_uv: no effect in forward run; but
208       get truncation error differences with adjoint exch.
209    o exch2:
210     - change index-bounds storage (moved from target to local tile,
211       more intuitive this way) ; rename/remove some variables.
212     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
213    
214    checkpoint61a
215    o exch2/matlab-topology-generator:
216      fix bug in index bounds for N-S internal exchange (hard to tell if this
217      had any effect on the solution).
218    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
219      is exceeded
220    o testreport: modify syntax of awk, so that it works also with
221      awk, and not only with nawk and gawk
222    
223    checkpoint61
224    o autodiff
225      Change default for TAF usage by removing argument '-nonew_arg'
226      This changes TAF subroutine argument list (ordering of active var.)
227      Omission of this flag leads to incompatibility w.r.t. TAMC
228      To restore TAMC-compatibility, need following modifs:
229      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
230      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
231      Tested TAF version is 1.9.22
232      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
233    
234    checkpoint60
235    --->>> This is the last checkpoint for which generating the adjoint
236    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
237    --->>> by default.
238    --->>> Future checkpoints will ommit this flag by default.
239    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
240    o pkg/grdchk: Add gradient check to etan0 perturbations.
241    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
242    o pkg/autodiff: more flexibility in zeroadj.
243      model/src: modifying do_oceanic_phys.F accordingly.
244    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
245    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
246      special setup of gmredi for which the adjoint is stable
247      enough for parameter optimization.
248    o bridging the gap between eddy stress and GM.
249      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
250          along with a change in CPP option (now ALLOW_EDDYPSI).
251      -> when using GM w/ GM_AdvForm:
252          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
253          is applied either in the tracer Eq. or in momentum Eq.
254          depending on data.gmredi (intro. GM_InMomAsStress).
255      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
256      The key modifications are in model/src/taueddy_external_forcing.F
257      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
258    
259    checkpoint59r
260    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
261      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
262      fix option to read coriolis(@ cell-corner) from files with CS-grid.
263    o pkg/mnc: add some attributes to standard 1D-coordinate variables
264    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
265      mass points, when using mnc for output
266      - add runtime parameter (missing_value, missing_value_int) to override
267        default (which is the value of getcon('UNDEF'))
268    o pkg/mnc: prepare mnc for the actual use of missing values with the
269      diagnostics package: small fix in mnc_cw_readwrite.template and more
270      initialisation of never used fields
271      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
272      versions
273    o pkg/thsice/thsice_ini_vars.F added default initial values so that
274      thermodynamics sea ice solver does not blow up when some initial fields
275      are missing.
276    o move from external_forcing_surf.F to ini_forcing.F
277      the p-coord. hack consisting in using pLoad to set phi0surf ;
278      update output of tutorial_global_oce_in_p (affected @ truncation level).
279    o Freshen up a bit hs94.1x64x5, notably:
280      remove rotationPeriod and tRef=5*0. (adjoint only), and add
281      exactConserv=.TRUE.
282    o pkg/generic_advdiff:
283      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
284      applies to files where Temperature & Salinity 2nd Order moments are used.
285    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
286      this uses a dynamically allocated internal state data structure
287      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
288      and requires a fortran 90 compiler
289    
290    checkpoint59q
291    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
292       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
293    o Refresh tutorial_global_oce_biogeo, notably:
294      - change bathymetry (put back seamounts in ACC, use hFacs)
295      - change EOS (POLY3 --> JMD95Z)
296      - use Bryan-Lewis vertical diffusivity
297      - use multidimensional advection
298      - remove old virtual virtual in dic pkg, now done through ptracer pkg
299      - change a couple of parameters in dic pkg
300    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
301    o pkg/obcs: change default to OBCSfixTopo = .true.,
302      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
303      - replace "debugMode" with "debugLevel .GE. debLevB"
304    o implementation of TAF directives for gchem,cfc,dic
305    o remove "exp5" (replaced by tutorial_deep_convection).
306    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
307      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
308      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
309      --> changes results in exp4, seaice_obcs
310    o tutorial_deep_convection :
311      update the set-up and increase resolution and domain size ; start
312      from pseudo initial conditions = output at t=120mn in order to see
313      something happening when running testreport.
314    o pkg/seaice: add os7mp as an advection scheme
315                  add check for advection schemes
316                  add a flag for restoring T and S underneath sea ice
317    o pkg/my82: add netcdf-support and diagnostics
318    o thsice pkg:
319      - Now hsMax limits snow height by turning it into ice following
320        flooding scheme (and now conserving energy)
321      - Slight rewriting of the formula in thsice_calc_thick.F
322      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
323      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
324    
325    checkpoint59p
326    o gchem / dic / cfc :
327      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
328      - add new parameter files: "data.dic" & "data.cfc" ;
329      - various re-arrangement in initialisation & header file ;
330      - fix tutorial_global_oce_biogeo for multi-threaded test.
331    o pkg/dic: test for "pickup_dic" file when restarting ;
332      if no pickup-file, can restart with a re-initialised pH (same as it did
333      before) providing pickupStrictlyMatch is set to False.
334    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
335      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
336    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
337      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
338    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
339     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
340       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
341    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
342       scheme to use for vorticty-term ;
343     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
344       (with default selectVortScheme, return to original discretisation)
345     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
346    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
347    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
348      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
349      also fix diagnostics VISCAHW & VISCA4W.
350    
351    checkpoint59o
352    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
353    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
354      move a few statemens out the main loop into separate loops
355    o pkg/shelfice:
356      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
357        (kg/m^2/s), does not break tests, because in verification/isomip,
358        rhoConstFresh=rhoConst (by accident)
359      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
360      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
361        new file model/src/seawater.F, so that they are available for all pkgs.
362      - convert potential temperature into in-situ temperature. This changes the
363        isomip tests => update tests
364    o add a flag writePickupAtEnd (default=true) to be able to suppress
365      writing a pickup at the last timestep
366    o tools/mpack-1.6 :
367      - disable automake (not working) and autoconf (not needed).
368      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
369        also cleaner with much less compilation warnings.
370    o pkg/profiles:
371      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
372      (for "less than 32 characters name" compiler requirement)
373    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
374      conditions that have a different sampling frequency than S/T/U/V obcs
375    o pkg/diagnostics (stats-diags):
376      - fix global Min/Max in case 1 processor get only empty tiles
377    o genmake2: replace (4 times)
378         make genmake_tc_1.o >> genmake_warnings 2>&1
379      with
380         COMM="$CC $CFLAGS -c genmake_tc_1.c"
381         echo $COMM >> genmake_warnings
382         $COMM >> genmake_warnings 2>&1
383      to make genmake2 always see the value of CC as specified in the optfile.
384    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
385      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
386      - modify verification advect_cs test to test SOM-advection on CS-grid.
387    o pkg/ctrl:
388      - Rewrite of ctrl_map_ini_ecco.F,
389        introducing a generic routine (ctrl_map_ini_gen.F).
390      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
391    
392    checkpoint59n
393    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
394      number in dedicate array "hdiag":
395      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
396        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
397      - many small changes (integer format) for large number of diagnostics
398      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
399        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
400    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
401      usingSphericalGrid, this allows to define the rotated grid coordinates
402      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
403      geographical coordinates according to the inverse of the rotation defined
404      by the Euler angles, so that Coriolis parameter and online-interpolation by
405      exf works with the geographical coordinates on XC/YC/XG/YG.
406      Naturally, this feature does not work with all packages, so some
407      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
408      profiles), because there the coordinates are assumed to be regular
409      spherical grid coordinates.
410    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
411      - introduce isopycnal diffusion coefficient control.
412    o tools/adjoint_options:
413      - additional control vector components.
414    o pkg/mnc: have mnc create marginally meaning full coordinate variables
415      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
416    o pkg/mypackage:
417      - add example of read/write pickup for state-var ;
418      - add entry points to the main code for state-vars diags & write-pickup.
419    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
420      transitions for useExfYearlyFields
421      - add new subroutine that determines the file to read from for
422        use*YearlyFields = .TRUE. and .FALSE.
423      - add a verification experiment to global_with_exf that tests
424        useExfYearlyFields with USE_EXF_INTERPOLATION defined
425    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
426      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
427      subroutines (which could be generated from a template, because they are
428      almost identical), for now they are included in obcs_prescribe_read.F for
429      simplicity
430    o pkg/exf:
431      - add a little more diagnostic to exf_interp_read (in analogy to
432        mds_read_field, can be turned off with debugLevel < debugLevA=1)
433      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
434        ugly but fast by unrolling short inner loops, inserting a unroll=8
435        directive in routine lagran, and splitting a loop and making do while the
436        outermost loop (the latter requires the intoduction of index arrays)
437    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
438    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
439      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
440    o verification/seaice_obcs: updated for restart test and latest options
441    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
442      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
443      for now this is only available for the C-grid code and also within
444      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
445    
446    checkpoint59m
447    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
448      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
449    o gad_som : fix flux output (& diagnostics) to have same units as other  
450      advection scheme fluxes (was previously multiplied by deltaT).  
451    o added verification/seaice_obcs both to test seaice open boundaries
452      and to provide an example matlab scrpt for generating them
453    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
454    o pkg/salt_plume: clean up salt_plume_frac.F to
455      remove redundancy in PlumeMethod 1 and 4
456    o pkg/kpp: added saltplume diagnostics
457    o pkg/obcs and pkg/seaice:
458      - do not set uice and vice to zero when OB*icefile are unspecified
459      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
460      - moved seaice tracer obcs after call to seaice_growth
461    o pkg/salt_plume: added various options for salt plume depth
462      criterion and for vertical distribution of the salt
463    
464    checkpoint59l
465    o pkg/ptracers: new version of ptracers pickup:
466      read meta file and write only fields which are needed to restart.
467      ( same logic as main pickup file ; also using pickupStrictlyMatch )
468    o pkg/seaice:
469      - add timescale for melting due to warm mixed layer as a means of
470        setting SEAICE_availHeatFrac more conveniently
471      - add a CPP-flag/runtime parameter check for flooding algorithm
472      - reformulated availHeat in seaice_growth.F to be independent of AREA
473    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
474      unit changes
475    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
476    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
477      SX vector computer.
478    o pkg/seaice:
479      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
480        seaice forcing fields can now be read only through pkg/exf
481      - removed some unused halos
482    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
483    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
484      or U/VICE from U/VWIND before computing U/VSTRESS
485    
486    checkpoint59k
487    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
488      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
489    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
490      all experiments pass when compile with un-initialised var. checking option.
491    o added pkg/salt_plume
492    o script to test restart (for now, in MITgcm_contrib/jmc_script)
493    o pkg/seaice: new read/write pickup version.
494      read meta file and write only fields which are needed to restart.
495      ( same logic as main pickup file ; also using pickupStrictlyMatch )
496    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
497    o lab_sea.hb87: modify the domain & update output.hb87.txt :
498      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
499      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
500      process. Fixed here by closing the domain at the Northern boundary.
501    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
502    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
503      a set of consecutive levels in/from a 3-D array.
504    o pkg/ptracers:
505      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
506      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
507    
508    checkpoint59j
509    o in pkgs: dic, obcs, offline, rbcs:
510      standard way to compute coeff. for time interpolation between 2 time reccords
511      which retains full precision (& make results less dependent on compiler).
512      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
513    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
514      packages instead of reading ice cover and wind speed separately
515    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
516     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
517      to allow to compile customized code before the update)
518    o cleaning-up:
519      - fix CPP instruction syntax in pkg/obcs
520      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
521        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
522      - fix some threads issue in IO parts.
523    o pkg/dic:
524      - add tons of "_d 0" (--> much better testreports !)
525       and then update outputs of tutorial_global_oce_biogeo
526    o pkg/mom_fluxform:
527      add a special version of momentum advection intended to conserve momentum
528      next to a bathymetry step or a coastline edge. (default = off = #undef)
529    o new read/write pickup version:
530      - for now, only implemented for main (mdsio) pickup file.
531      - write out only what is needed to restart; merge pickup_nh , pickup_ph
532        and main pickup together.
533      - read meta file; read only what is needed to restart; stop if a field
534        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
535        if it make sense (even if the restart is not perfect).
536      - if no meta file, assume that pickup to read corresponds exactly to
537        a pickup that would currently be written.
538      - read pickup written in the old format (until checkpoint59i) if it
539        recognizes an old meta file (no field-list).
540      - add a meta file in exp. which starts from a pickup: 2 cases:
541        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
542         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
543        b) a meta file describing the content of the associated pickup file
544         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
545    o pkg/mdsio & pkg/rw:
546      - new routine to read a meta file ; new set of routine to read
547        Multiple-fields file (with meta file).
548    o added open boundary conditions capability for seaice
549        HSNOW, HSALT, UICE, and VICE
550    
551    checkpoint59i
552    o adjoint:
553      * fix multiDimAdvection adjoint
554        (partial recomputation problem by TAF for fVerT(:,:,kDown)
555        and comlev1 size definition (maxpass vs. max. number of tracers)
556      * verification/global_ocean.90x45x15 adjoint now tests
557        NLFS and multiDimAdvection using DST3 (=30)
558      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
559    o pkg/kpp: add "_d 0" to real constant (if missing);
560      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
561      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
562    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
563      for internal parameters related to restart process (formerly from PARAMS.h)
564      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
565    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
566      as argument. (only atm2d & obcs write_pickup have not yet been updated)
567    o pkg/monitor:
568      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
569      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
570      - account for deep Atmosphere factor and density factor (anelastic)
571    o added open boundary conditions capability for seaice HEFF and AREA
572    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
573      thermodynamics
574      - requires a little reorganization, which affects the testreport results
575        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
576        so that now the conservative form is tested
577      - add a few comments
578    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
579    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
580    o add new diagnostics to seaice: advective, diffusive fluxes (only for
581      multidim-advection, for scheme 2 they are not filled) and transports,
582      thermodynamic growth rates
583    o change units of EmPmR (inside the code, + within coupling interface)
584      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
585      Affects results @ truncation level (cg2d match) and update output of
586       experiments: lab_sea(6), global_ocean.90x40x15(10),
587      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
588      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
589      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
590      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
591    
592    checkpoint59h
593    o pkg/exf:
594      - improve vectorization by moving if-statement out of loops in
595        exf_mapfields, exf_radiation
596      - exf_bulkformulae.F: introduce 2D fields and vectorize code
597    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
598    o testreport:
599      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
600        monitor & update offline_exf_seaice exp. output.
601      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
602    o pkg/seaice:
603      - bug fix in the evp solver: boundary conditions were affected be
604        masking of zMax/zMin (changes results)
605      - minor bug fix in boundary conditions in seaice_calc_strainrates
606        (changes results for no_slip)
607      - seaice_lsr.F: make interpolation of eta dependent on boundaries
608      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
609      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
610        stress formulation and no-slip boundary conditions
611    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
612      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
613    o pkg/seaice: a first HSALT time stepping equation has been checked in
614    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
615      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
616      without requiring DO-IF statements
617    o pkg/thsice:
618      use continuous power-law function for partition of energy between lateral
619      melting/freezing and thinning/thickening ; old code using step function
620      still available with #undef THSICE_FRACEN_POWERLAW
621      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
622    o testreport: change AD testing : check against results/output_adm.txt
623      using same scripts as for forward test.
624    
625    checkpoint59g
626    o adjoint testing: in preparation for changing testreport:
627      - output format: cost and grad written on separated lines
628      - ad output results in directory "results" (instead of "results_ad")
629  o pkg/seaice: adding ice salinity HSALT as a prognostic variable  o pkg/seaice: adding ice salinity HSALT as a prognostic variable
