4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o remove backward compatibility for thetaMin,phiMin
8      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
9    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
10      interpolated wind field not only for curvilineargrid=.true., but also
11      for a rotated grid (rotateGrid=.true.)
12    o pkg/exf: add capability to bypass interpolation for runoff
13      by setting yet another CPP-flag
14    o eesupp/src, B-grid exchange:
15      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
16    o autodiff
17      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
18      allows to switch to single-prec common blocks;
19      corresponding switch occurs in tamc.h, integer isbyte
20      TAF store directivs "byte" and "kind" seem equivalent;
21      Most tamc.h have been updated correspondingly.
22    
23    checkpoint61i
24    o autodiff:
25      fix autodiff_sore/_restore indices for obcs
26      (spotted by I. Hoteit, M. Mazloff)
27    o pkg/autodiff, pkg/ctrl:
28      Add flag to reduce all tapelev I/O to single-prec.
29      In data.ctrl set
30        doSinglePrecTapelev = .TRUE.
31    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
32      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
33    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
34      real fresh water flux (not yet)
35    o pkg/mdsio & rw:
36     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
37     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
38    o pkg/flt:
39     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
40       init_fixed & ini_varia.
41     - clean-up & simplify linear interpolation S/R:
42       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
43     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
44     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
45     - add vert. coordinate & horiz. indices to output files.
46     - change vertical position in initial condition, from index to depth [m].
47     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
48       (easier to get to a curvilinear grid) ; delX,delY no longer used.
49    o pkg/ggl90: a few modifications:
50     - fix bottom boundary condition, and interpolation of KappaE
51       near top and bottom
52     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
53     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
54     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
55    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
56      (maintain temporary backward compatibility, until next checkpoint)
57    
58    checkpoint61h
59    o pkg/diagnostics with "periodic averaging diagnostics":
60      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
61    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
62    o pkg/obcs: fix loop ranges for balancing code
63    o pkg/flt:
64     - improve criteria for finding which tile owns a float.
65     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
66    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
67      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
68      with ocean biogeo)
69    o pkg/flt:
70     - do some cleaning and fix the restart ;
71     - add output.txt in flt_example/results to get this pkg tested.
72    o genmake2: add an EXTENDED_SRC option and flag.
73       for now, cannot be turned on on command line (only through genmake_local)
74    o pkg/mdsio: read/write vector:
75     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
76     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
77       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
78     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
79      (drop to 4 digits matching for grad). But this test does not look very
80      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
81    
82    checkpoint61g
83    o pkg/flt:
84      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
85       + make OPTIONS file more standard.
86      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
87      - fix _BYTESWAPIO CPP-Flag
88      - standard reading of file-parameter "data.flt"
89      - fix argument list of S/R FLT_RESTART
90      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
91    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
92    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
93      a still unfixed compiler/optimization bug
94    
95    checkpoint61f
96    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
97      update results of global_ocean.cs32x15.icedyn test.
98    o move getcon.F from model/src to pkg/fizhi.
99    o pkg/exf: add parameter for extrapolation of temp up to the surface
100       and option to prevent negative evap (in bulk_largeyeager04 only).
101    o Prather Advection scheme: fix tracer conservation for divergent flow
102      (e.g., when using NonLin Free-Surface).
103    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
104    o gmredi (Visbeck-variable-K):
105     - add more parameters to Visbeck-variable-K.
106     - use a 5 points average for dSigmaR in Visbeck-K calculation
107       (more "homogenous": same stencil and same weights as in dSigmaH)
108     - update output of ideal_2D_oce experiment.
109    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
110      (#undef REAL4_IS_SLOW)
111     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
112       coordinate variable
113     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
114       (surface forcing fields), removes some of the functionality
115     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
116     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
117       probably not all: copy _RS surface flux fields to RL field before
118       calling DIAGNOSTICS_FILL
119     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
120       real*4 (CALL EXCH_*_RS) versions.
121     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
122       (generate new output).
123    
124    checkpoint61e
125    o gmredi (Visbeck-variable-K):
126      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
127      - change computation of Visbeck-K where Slope > Smax :        
128        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
129        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
130    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
131      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
132    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
133    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
134      does not become too large (to avoid precision problems in implicit-diffusion
135      solver); update ideal_2D_oce output.
136    o pkg ggl90:
137      - in ggl90_cal.F: compute only one set of visc/diff, used to
138        step forward TKE/T/S/momentum
139      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
140        have Prandlt =1)
141    o gmredi (fm07):
142      - add lower limit on Transition layer thickness + lower limit on 1/lambda
143      - allow to set few more params from data.gmredi
144    o pkg ggl90:
145          - add missing sqrt(2) factor in computation of mixing length
146            scale in ggl90_calc.F
147            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
148    
149    checkpoint61d
150    o adjoint modifs
151      - adapt to new field rhoInSitu
152      - allow to revert from StoreDynVars2D, StoreDynVars3D
153        to individual fields
154        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
155    o store 3-D (in-situ) density in commom block (DYNVARS.h)
156     - save 1 rho computation.
157     - no longer modify T & S inland when using down_slope pkg.
158    o gad_som : allow to switch to SOM advection for T & S without corresponding
159      pickup files (using new S/R: MDS_CHECK4FILE).
160    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
161      (for useSingleCpuIO to work in multi-threaded)
162    o pkg/shelfice:
163     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
164       with SHELFICEtopoFile in data.shelfice
165     - move code for reading ice shelf topography and modifying hFacC into separate
166       subroutines of the shelfice package
167     - separate initialisation of "fixed" and "variable" variables
168     - kTopC is not (yet) replaced by kSurfC, although this is possible
169    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
170    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
171      and rename:
172      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
173      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
174    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
175    
176    checkpoint61c
177    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
178      to add mass source/sink of fluid in the interior (3-D generalisation
179      of oceanic real-fresh water flux).
180    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
181    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
182    o new pkg: down_slope
183      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
184      - presently, modify T & S inland (dwnslp_calc_rho.F).
185        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
186      - implementation for ocean in P-coords not tested.
187      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
188    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
189      (to facilitate conversion of oceanic pkg to p-coordinate).
190    o change FIND_RHO to FIND_RHO_2D :
191      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
192    o new pkg: cheapaml
193    
194    checkpoint61b
195    o exch2:
196      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
197      - no longer depend on the order sequence (N,S,E,W).
198      - 3rd exchange no longer needed (tested with 24 tiles).
199      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
200      - exch_UV_A-grid readily available (but not yet tested).
201      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
202      (both are no longer needed) in exch_uv: no effect in forward run; but
203       get truncation error differences with adjoint exch.
204    o exch2:
205     - change index-bounds storage (moved from target to local tile,
206       more intuitive this way) ; rename/remove some variables.
207     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
208    
209    checkpoint61a
210    o exch2/matlab-topology-generator:
211      fix bug in index bounds for N-S internal exchange (hard to tell if this
212      had any effect on the solution).
213    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
214      is exceeded
215    o testreport: modify syntax of awk, so that it works also with
216      awk, and not only with nawk and gawk
217    
218    checkpoint61
219    o autodiff
220      Change default for TAF usage by removing argument '-nonew_arg'
221      This changes TAF subroutine argument list (ordering of active var.)
222      Omission of this flag leads to incompatibility w.r.t. TAMC
223      To restore TAMC-compatibility, need following modifs:
224      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
225      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
226      Tested TAF version is 1.9.22
227      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
228    
229    checkpoint60
230    --->>> This is the last checkpoint for which generating the adjoint
231    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
232    --->>> by default.
233    --->>> Future checkpoints will ommit this flag by default.
234    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
235    o pkg/grdchk: Add gradient check to etan0 perturbations.
236    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
237    o pkg/autodiff: more flexibility in zeroadj.
238      model/src: modifying do_oceanic_phys.F accordingly.
239    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
240    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
241      special setup of gmredi for which the adjoint is stable
242      enough for parameter optimization.
243    o bridging the gap between eddy stress and GM.
244      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
245          along with a change in CPP option (now ALLOW_EDDYPSI).
246      -> when using GM w/ GM_AdvForm:
247          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
248          is applied either in the tracer Eq. or in momentum Eq.
249          depending on data.gmredi (intro. GM_InMomAsStress).
250      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
251      The key modifications are in model/src/taueddy_external_forcing.F
252      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
253    
254    checkpoint59r
255    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
256      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
257      fix option to read coriolis(@ cell-corner) from files with CS-grid.
258    o pkg/mnc: add some attributes to standard 1D-coordinate variables
259    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
260      mass points, when using mnc for output
261      - add runtime parameter (missing_value, missing_value_int) to override
262        default (which is the value of getcon('UNDEF'))
263    o pkg/mnc: prepare mnc for the actual use of missing values with the
264      diagnostics package: small fix in mnc_cw_readwrite.template and more
265      initialisation of never used fields
266      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
267      versions
268    o pkg/thsice/thsice_ini_vars.F added default initial values so that
269      thermodynamics sea ice solver does not blow up when some initial fields
270      are missing.
271    o move from external_forcing_surf.F to ini_forcing.F
272      the p-coord. hack consisting in using pLoad to set phi0surf ;
273      update output of tutorial_global_oce_in_p (affected @ truncation level).
274    o Freshen up a bit hs94.1x64x5, notably:
275      remove rotationPeriod and tRef=5*0. (adjoint only), and add
276      exactConserv=.TRUE.
277    o pkg/generic_advdiff:
278      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
279      applies to files where Temperature & Salinity 2nd Order moments are used.
280    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
281      this uses a dynamically allocated internal state data structure
282      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
283      and requires a fortran 90 compiler
284    
285    checkpoint59q
286    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
287       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
288    o Refresh tutorial_global_oce_biogeo, notably:
289      - change bathymetry (put back seamounts in ACC, use hFacs)
290      - change EOS (POLY3 --> JMD95Z)
291      - use Bryan-Lewis vertical diffusivity
292      - use multidimensional advection
293      - remove old virtual virtual in dic pkg, now done through ptracer pkg
294      - change a couple of parameters in dic pkg
295    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
296    o pkg/obcs: change default to OBCSfixTopo = .true.,
297      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
298      - replace "debugMode" with "debugLevel .GE. debLevB"
299    o implementation of TAF directives for gchem,cfc,dic
300    o remove "exp5" (replaced by tutorial_deep_convection).
301    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
302      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
303      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
304      --> changes results in exp4, seaice_obcs
305    o tutorial_deep_convection :
306      update the set-up and increase resolution and domain size ; start
307      from pseudo initial conditions = output at t=120mn in order to see
308      something happening when running testreport.
309    o pkg/seaice: add os7mp as an advection scheme
310                  add check for advection schemes
311                  add a flag for restoring T and S underneath sea ice
312    o pkg/my82: add netcdf-support and diagnostics
313    o thsice pkg:
314      - Now hsMax limits snow height by turning it into ice following
315        flooding scheme (and now conserving energy)
316      - Slight rewriting of the formula in thsice_calc_thick.F
317      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
318      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
319    
320    checkpoint59p
321    o gchem / dic / cfc :
322      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
323      - add new parameter files: "data.dic" & "data.cfc" ;
324      - various re-arrangement in initialisation & header file ;
325      - fix tutorial_global_oce_biogeo for multi-threaded test.
326    o pkg/dic: test for "pickup_dic" file when restarting ;
327      if no pickup-file, can restart with a re-initialised pH (same as it did
328      before) providing pickupStrictlyMatch is set to False.
329    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
330      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
331    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
332      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
333    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
334     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
335       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
336    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
337       scheme to use for vorticty-term ;
338     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
339       (with default selectVortScheme, return to original discretisation)
340     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
341    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
342    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
343      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
344      also fix diagnostics VISCAHW & VISCA4W.
345    
346    checkpoint59o
347    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
348    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
349      move a few statemens out the main loop into separate loops
350    o pkg/shelfice:
351      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
352        (kg/m^2/s), does not break tests, because in verification/isomip,
353        rhoConstFresh=rhoConst (by accident)
354      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
355      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
356        new file model/src/seawater.F, so that they are available for all pkgs.
357      - convert potential temperature into in-situ temperature. This changes the
358        isomip tests => update tests
359    o add a flag writePickupAtEnd (default=true) to be able to suppress
360      writing a pickup at the last timestep
361    o tools/mpack-1.6 :
362      - disable automake (not working) and autoconf (not needed).
363      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
364        also cleaner with much less compilation warnings.
365    o pkg/profiles:
366      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
367      (for "less than 32 characters name" compiler requirement)
368    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
369      conditions that have a different sampling frequency than S/T/U/V obcs
370    o pkg/diagnostics (stats-diags):
371      - fix global Min/Max in case 1 processor get only empty tiles
372    o genmake2: replace (4 times)
373         make genmake_tc_1.o >> genmake_warnings 2>&1
374      with
375         COMM="$CC $CFLAGS -c genmake_tc_1.c"
376         echo $COMM >> genmake_warnings
377         $COMM >> genmake_warnings 2>&1
378      to make genmake2 always see the value of CC as specified in the optfile.
379    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
380      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
381      - modify verification advect_cs test to test SOM-advection on CS-grid.
382    o pkg/ctrl:
383      - Rewrite of ctrl_map_ini_ecco.F,
384        introducing a generic routine (ctrl_map_ini_gen.F).
385      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
386    
387    checkpoint59n
388    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
389      number in dedicate array "hdiag":
390      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
391        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
392      - many small changes (integer format) for large number of diagnostics
393      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
394        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
395    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
396      usingSphericalGrid, this allows to define the rotated grid coordinates
397      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
398      geographical coordinates according to the inverse of the rotation defined
399      by the Euler angles, so that Coriolis parameter and online-interpolation by
400      exf works with the geographical coordinates on XC/YC/XG/YG.
401      Naturally, this feature does not work with all packages, so some
402      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
403      profiles), because there the coordinates are assumed to be regular
404      spherical grid coordinates.
405    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
406      - introduce isopycnal diffusion coefficient control.
407    o tools/adjoint_options:
408      - additional control vector components.
409    o pkg/mnc: have mnc create marginally meaning full coordinate variables
410      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
411    o pkg/mypackage:
412      - add example of read/write pickup for state-var ;
413      - add entry points to the main code for state-vars diags & write-pickup.
414    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
415      transitions for useExfYearlyFields
416      - add new subroutine that determines the file to read from for
417        use*YearlyFields = .TRUE. and .FALSE.
418      - add a verification experiment to global_with_exf that tests
419        useExfYearlyFields with USE_EXF_INTERPOLATION defined
420    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
421      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
422      subroutines (which could be generated from a template, because they are
423      almost identical), for now they are included in obcs_prescribe_read.F for
424      simplicity
425    o pkg/exf:
426      - add a little more diagnostic to exf_interp_read (in analogy to
427        mds_read_field, can be turned off with debugLevel < debugLevA=1)
428      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
429        ugly but fast by unrolling short inner loops, inserting a unroll=8
430        directive in routine lagran, and splitting a loop and making do while the
431        outermost loop (the latter requires the intoduction of index arrays)
432    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
433    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
434      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
435    o verification/seaice_obcs: updated for restart test and latest options
436    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
437      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
438      for now this is only available for the C-grid code and also within
439      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
440    
441    checkpoint59m
442    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
443      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
444    o gad_som : fix flux output (& diagnostics) to have same units as other  
445      advection scheme fluxes (was previously multiplied by deltaT).  
446    o added verification/seaice_obcs both to test seaice open boundaries
447      and to provide an example matlab scrpt for generating them
448    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
449    o pkg/salt_plume: clean up salt_plume_frac.F to
450      remove redundancy in PlumeMethod 1 and 4
451    o pkg/kpp: added saltplume diagnostics
452    o pkg/obcs and pkg/seaice:
453      - do not set uice and vice to zero when OB*icefile are unspecified
454      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
455      - moved seaice tracer obcs after call to seaice_growth
456    o pkg/salt_plume: added various options for salt plume depth
457      criterion and for vertical distribution of the salt
458    
459    checkpoint59l
460    o pkg/ptracers: new version of ptracers pickup:
461      read meta file and write only fields which are needed to restart.
462      ( same logic as main pickup file ; also using pickupStrictlyMatch )
463    o pkg/seaice:
464      - add timescale for melting due to warm mixed layer as a means of
465        setting SEAICE_availHeatFrac more conveniently
466      - add a CPP-flag/runtime parameter check for flooding algorithm
467      - reformulated availHeat in seaice_growth.F to be independent of AREA
468    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
469      unit changes
470    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
471    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
472      SX vector computer.
473    o pkg/seaice:
474      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
475        seaice forcing fields can now be read only through pkg/exf
476      - removed some unused halos
477    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
478    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
479      or U/VICE from U/VWIND before computing U/VSTRESS
480    
481    checkpoint59k
482    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
483      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
484    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
485      all experiments pass when compile with un-initialised var. checking option.
486    o added pkg/salt_plume
487    o script to test restart (for now, in MITgcm_contrib/jmc_script)
488    o pkg/seaice: new read/write pickup version.
489      read meta file and write only fields which are needed to restart.
490      ( same logic as main pickup file ; also using pickupStrictlyMatch )
491    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
492    o lab_sea.hb87: modify the domain & update output.hb87.txt :
493      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
494      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
495      process. Fixed here by closing the domain at the Northern boundary.
496    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
497    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
498      a set of consecutive levels in/from a 3-D array.
499    o pkg/ptracers:
500      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
501      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
502    
503    checkpoint59j
504    o in pkgs: dic, obcs, offline, rbcs:
505      standard way to compute coeff. for time interpolation between 2 time reccords
506      which retains full precision (& make results less dependent on compiler).
507      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
508    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
509      packages instead of reading ice cover and wind speed separately
510    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
511     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
512      to allow to compile customized code before the update)
513    o cleaning-up:
514      - fix CPP instruction syntax in pkg/obcs
515      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
516        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
517      - fix some threads issue in IO parts.
518    o pkg/dic:
519      - add tons of "_d 0" (--> much better testreports !)
520       and then update outputs of tutorial_global_oce_biogeo
521    o pkg/mom_fluxform:
522      add a special version of momentum advection intended to conserve momentum
523      next to a bathymetry step or a coastline edge. (default = off = #undef)
524    o new read/write pickup version:
525      - for now, only implemented for main (mdsio) pickup file.
526      - write out only what is needed to restart; merge pickup_nh , pickup_ph
527        and main pickup together.
528      - read meta file; read only what is needed to restart; stop if a field
529        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
530        if it make sense (even if the restart is not perfect).
531      - if no meta file, assume that pickup to read corresponds exactly to
532        a pickup that would currently be written.
533      - read pickup written in the old format (until checkpoint59i) if it
534        recognizes an old meta file (no field-list).
535      - add a meta file in exp. which starts from a pickup: 2 cases:
536        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
537         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
538        b) a meta file describing the content of the associated pickup file
539         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
540    o pkg/mdsio & pkg/rw:
541      - new routine to read a meta file ; new set of routine to read
542        Multiple-fields file (with meta file).
543    o added open boundary conditions capability for seaice
544        HSNOW, HSALT, UICE, and VICE
545    
546    checkpoint59i
547    o adjoint:
548      * fix multiDimAdvection adjoint
549        (partial recomputation problem by TAF for fVerT(:,:,kDown)
550        and comlev1 size definition (maxpass vs. max. number of tracers)
551      * verification/global_ocean.90x45x15 adjoint now tests
552        NLFS and multiDimAdvection using DST3 (=30)
553      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
554    o pkg/kpp: add "_d 0" to real constant (if missing);
555      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
556      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
557    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
558      for internal parameters related to restart process (formerly from PARAMS.h)
559      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
560    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
561      as argument. (only atm2d & obcs write_pickup have not yet been updated)
562    o pkg/monitor:
563      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
564      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
565      - account for deep Atmosphere factor and density factor (anelastic)
566    o added open boundary conditions capability for seaice HEFF and AREA
567    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
568      thermodynamics
569      - requires a little reorganization, which affects the testreport results
570        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
571        so that now the conservative form is tested
572      - add a few comments
573    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
574    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
575    o add new diagnostics to seaice: advective, diffusive fluxes (only for
576      multidim-advection, for scheme 2 they are not filled) and transports,
577      thermodynamic growth rates
578    o change units of EmPmR (inside the code, + within coupling interface)
579      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
580      Affects results @ truncation level (cg2d match) and update output of
581       experiments: lab_sea(6), global_ocean.90x40x15(10),
582      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
583      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
584      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
585      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
586    
587    checkpoint59h
588    o pkg/exf:
589      - improve vectorization by moving if-statement out of loops in
590        exf_mapfields, exf_radiation
591      - exf_bulkformulae.F: introduce 2D fields and vectorize code
592    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
593    o testreport:
594      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
595        monitor & update offline_exf_seaice exp. output.
596      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
597    o pkg/seaice:
598      - bug fix in the evp solver: boundary conditions were affected be
599        masking of zMax/zMin (changes results)
600      - minor bug fix in boundary conditions in seaice_calc_strainrates
601        (changes results for no_slip)
602      - seaice_lsr.F: make interpolation of eta dependent on boundaries
603      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
604      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
605        stress formulation and no-slip boundary conditions
606    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
607      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
608    o pkg/seaice: a first HSALT time stepping equation has been checked in
609    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
610      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
611      without requiring DO-IF statements
612    o pkg/thsice:
613      use continuous power-law function for partition of energy between lateral
614      melting/freezing and thinning/thickening ; old code using step function
615      still available with #undef THSICE_FRACEN_POWERLAW
616      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
617    o testreport: change AD testing : check against results/output_adm.txt
618      using same scripts as for forward test.
619    
620    checkpoint59g
621    o adjoint testing: in preparation for changing testreport:
622      - output format: cost and grad written on separated lines
623      - ad output results in directory "results" (instead of "results_ad")
624    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
625    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
626    o pkg/ecco: allow user defined cost function contributions
627    o testreport:
628      Allow to choose (per experiment) the list of tested output variables
629       and the main variable (used to issue a pass/FAIL ) ;
630      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
631      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
632      Also modify printing of summary:
633       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
634       b) echo the list of tested variables in the individual summary.txt of
635          each experiment.
636    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
637      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
638      (but still depend on the tile decompostion of the domain).
639    o pkg/seaice: change a discretization detail to make the B-grid code
640      "more symmetric". This change is likely to remove all "ridges/leads" that
641      where quasi-aligned with the grid in B-grid solutions. It may also be
642      the solution to the stress coupling issues with the B-grid.
643    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
644      remove .cvsignore from input dir. (since testreport no longer run here).
645    o pkg/thsice:
646     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
647     - fix reshaping of sea-ice just after advection:
648       melt all the ice only if ice-volume is too small.
649     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
650       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
651     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
652    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
653      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
654    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
655      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
656      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
657      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
658      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
659      -> update output.txt
660    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
661     this affects truncation error: -> update output.txt of exp:
662      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
663      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
664    
665    checkpoint59f
666    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
667    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
668      a bounded range (in forward mode)
669    o pkg/ecco, ctrl, autodiff and mom_common:
670     internal parameter controls, completements of implementations
671    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
672    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
673      (not seem any difference in testing results).
674    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
675       at face corners.
676    o pkg/generic_advdiff:
677     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
678      loop range indices for computing vertical advection tendency
679      and do the calculation in the interior only (no overlap) ;
680      for now, only implemented for SOM advection (to save CPU time).
681     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
682    o exch2 adjoint
683      First set of changes:
684      - add exch2 hand-written adjoint templates
685      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
686        This will require cleanup in pkg/autodiff/*.F
687        (changed routines currently kept separate in verif. code/)
688      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
689        that used to hide exch2 or cubed-sphere specific code
690        (commented via 'cph-exch2')
691    o pkg/seaice
692      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
693    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
694       output of global_ocean.cs32x15.thsice .
695    
696    checkpoint59e
697    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
698      for B-grid vector (not yet tested) and C-grid vector (<- only used
699      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
700    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
701      (#ifdef ALLOW_SALT_PLUME)
702    o gather_2d/scatter_2d: removed halo regions
703    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
704      scheme and the corresponding test case (under front_relax dir). For now,
705      only available with Skew-flux form and not yet tested in realistic set-up.
706      adjoint: store directives updated, but gradient checks deteriorated,
707      so maybe GM/Redi adjoint is now broken.
708    o seaice adjoint
709      * add AREA, HEFF, HSNOW as control variable
710        (should not change lab_sea results)
711      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
712    o pkg/seaice:
713      * added computation of saltFlux in seaice_growth;
714        For time being, sea ice salinity is assumed constant
715        contribution of snow flooding to freshening of sea ice is neglected.
716        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
717        defaults to 0.0 in order to maintain backward compatibility.
718        Typical values for SEAICE_salinity are 4 to 10 g/kg.
719      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
720      * added SEAICE_availHeatFrac, which specifies fraction of surface level
721        heat content used to melt or grow ice
722      * commented out cap of HICE: it helps keep ice thinner
723      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
724      * applied OBCS T/S mask to HEFFM sea ice mask
725    
726    checkpoint59d
727    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
728     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
729     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
730    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
731     and change default value of parameter "GM_Small_Number";
732     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
733       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
734       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
735    o pkg/ecco: cost function when applying pkg/smooth to controls
736    o pkg/ctrl: add forcingPrecond run time parameter
737    o pkg/seaice:
738     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
739     - fix bug in metric terms of u-equation in LSR solver (implicit part),
740       changes verification/lab_sea
741     - rearrange implicit part of u-equation in LSR solver to make it easier to
742       read, understand, and debug. This causes changes at the truncation level.
743     - fix (serious) bug in the boundary conditions (sign error in the implicit
744       part) of the LSR solver. Changes all LSR results.
745     - fixed problem with HSNOW initialization to avoid thick snow when AREA
746       is initilized with small values - does not change lab_sea results.
747     - added HsnowFile initialization capability
748    o pkg/smooth: addition to model/src and pkg/ctrl so allow
749     initialization of pkg/smooth and application to control vector
750    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
751    o dependencies: pkg/profiles requires pkg/cal
752    o pkg/profiles:
753     - added option ALLOW_PROFILES_GENERICGRID
754         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
755         that interpolation information (grid points and coefficients) is provided
756         within the netcdf input files.
757         -> sample matlab scripts can be found in MITgcm_contrib/gael
758         that allow you to prepare netcdf input files.
759     - also modified: cleaner include statements, cleaner error print statements,
760       cleaner stops when error, and more tests of the netcdf input files consistency.
761    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
762    o pkg/seaice:
763     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
764       requires a new routine: seaice_diagnostics_fill.F
765     - make sure that seaice does not move if not forced (pressure replacement
766       method, Hibler and Ip, 1995), changes results
767     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
768     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
769       It is turned off by default (=-1.), because it changes the results.
770     - make it possible to read AREA from a file, too.
771    
772    checkpoint59c
773    o add S/R and diagnostics for oceanic mixed-layer depth
774    o move GMRedi call after all vertical mixing schemes (including KPP)
775    o pkg/thsice:
776     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
777      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
778    o pkg/obcs:
779     - bug fix for balance code
780    o pkg/seaice:
781      - allow values of SEAICE_elasticParm > 1
782      - add new parameter SEAICE_evpTauRelax as an alternative
783        to SEAICE_elasticParm
784      - make lsr boundary conditions free slip (by default), changes result
785      - add code for no slip boundary conditions for lsr
786      - set minimum of zeta to zero (and not 4e8) (changes results)
787      - add a cap on AREA after advecting AREA if seaice_growth is not called
788    o change calculation of Visbeck K:
789      - no longer depend on tapering scheme; instead, compute slope (limited
790        by GM_maxSlope). this is equivalent to what was comuted before with
791        clipping or linear tappering.
792      - fix vertical averaging (wrong by 1/2 level)
793      - leave the old version (but will not be maintained) within
794        #ifdef OLD_VISBECK_CALC / #endif
795      - update output of exp. ideal_2D_oce
796    o change error catch in calc_r_star to improve vectorization
797    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
798      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
799    o adjoint:
800      Re-organized adjoint checkpointing according to Matt Mazloff
801      (but with modifs/completions/cleanups)
802      Storing is now bundled into large arrays to optimized I/O
803      (and second step in cleanup of the_main_loop)
804    
805    checkpoint59b
806    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
807      - export/import (between ocean & coupler) fields needed for ocean DIC.
808    o pkg/seaice:
809      - get rid of three more exchanges seaice_calc_viscosities (required
810        different loop boundaries in seaice_lsr and seaice_ocean_stress)
811      - bug fix in seaice_ocean_stress (update of lab_sea required)
812      - reduce loop boundaries to necessary minimum also in seaice_evp
813      - go back to the old way of computing deltaC/Z as the adjoint likes that
814        better
815    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
816      passive tracer to an Age Tracer) + update output.txt
817    o pkg/exf:
818      - implement A-grid / C-grid selection for wind-stress input files.
819      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
820      for now, in exf_bulk_largeyeager04.F only :
821      - change implementation for case where windspeed + 2. components wind-stress
822        are read-in. AND use rhoConstFresh to convert evap.
823    o pkg/seaice:
824      - use correct EXCH_UV for wind-forcing (on A-grid).
825      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
826        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
827    o pkg/exf:
828      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
829      EXF_INTERPOLATION:
830      - merge global_with_exf/code version of exf_interp_read.F
831        to the main code ;
832      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
833        reading the file ; Important: This options needs to be defined to recover
834        previous code.
835        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
836      - no longer loose real*8 precision along the way when using exf_iprec=64.
837    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
838      - change discretisation of evp-solver in order to avoid another exchange
839        (changes lab_sea) and clean up a little
840      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
841        help the adjoint (this also changes the results slightly)
842      - add a few "_d 0" where they had been missing in seaice_evp.F
843      - cleaning up: remove unused seaice_calc_rhs.F
844    o pkg/exf: some cleaning-up:
845      - change various "constants" into runtime parameters
846      - cleaned-up Large&Yeager04 routine which should eventually
847        replace exf_bulkformulae.F (changed names of S/R and CPP)
848        and merged various ALLOW_ATM_WIND options
849     only used with thsice pkg (in thsice_get_exf.F):
850      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
851        which are used when useStabilityFct_overIce=TRUE (= the default)
852      - change default values of ice & snow emissivity and scale downward LW
853        by ice & snow emissivity.
854    o pkg/thsice:
855     fix few little problems, in thsice_calc_thickn.F:
856      - growth vertically (and not laterally) if iceFrac == iceMaskMax
857      - melt only laterally if hIce < hThinIce (as the comments say)
858      and in thsice_extend.F:
859      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
860      - start to form ice as soon as the minimum ice-volume is reachable.
861     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
862      and cpl_aim+ocn
863    o pkg/kpp
864     - move computation of surface related input fields to KPP into a new
865       subroutine kpp_forcing_surf.F
866     - remove wrong (within bi,bj loops) EXCH calls.
867     - little cleaning (add argument myThid in last position, cvs header ...)
868     - for now, fix conservation problem by exchanging KPPviscAz (may not
869       be the best fix)
870    o pkg/seaice
871     - check for inconsistent evp parameter/cpp-flag combination
872     - remove leftover errIO flat for obsolete name list error handling
873    o OpenAD
874     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
875    
876    checkpoint59a
877    o pkg/seaice: some parameter clarifications and a little bit of clean up
878    o pkg/thsice: rename run-time parameters:
879       himin       -> hIceMin
880       himin0      -> hThinIce
881       hihig       -> hThickIce
882       i0          -> i0swFrac
883       transCoef   -> bMeltCoef
884       frac_energy -> fracMelting
885      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
886       with default values (for now) that do not change the results.
887      remove old version of thsice vars advection in pkg/seaice.
888    o in FFIELDS.h:
889      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
890      - make pLoad & sIceLoad always available (but still only used if
891         ATMOSPHERIC_LOADING is #define).
892    o pkg/kpp: replaced _KPP_RL with _RL
893    o bug fixes for vertical diffusivity computations when both KPP and
894        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
895        are no longer updating the vertical diffusivity array
896        (passed as argument) but are (re-) setting those arrays.
897    o pkg/seaice: fix bug in evp solver, while doing that
898      - change (improve?) discretization of stress computations for both
899        cgrid-lsr and evp solver
900      - add a new routine to compute strain rates
901      - the above changes lab_sea results
902      - add no slip conditions for evp solver (off by default), lsr-version
903        may follow
904      - fix exchange for shear at Z-points (does not change lab_sea)
905      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
906        (to force the user to pick a time step since there is not "safe" way
907        of choosing it)
908      - add principal stress diagnostics
909      - rearrange fields for evp a little to avoid having to call a: too many
910        exchanges and b: exchanges for stress trensor components which we do
911        not have.
912      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
913        of evp, complete rewrite for lsr case (latter is does not yet work
914        in all cases)
915    o pkg/kpp: add code to have mixing in shelf ice caverns
916      - add myThid to all kpp routines (long overdue)
917    
918    checkpoint59
919    o pkg/exf:
920      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
921        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
922      - move exf header files from lower_case.h to UPPER_CASE.h ;
923        add missing cvs Header & Name
924      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
925      - add namelist param. selectStressGridPosition, exf_monFreq
926      - retire many _CLIM routines, and remove data.exf_clim
927        + params moved to data.exf
928        + climsst, climsss now handled by exf_set_gen, i.e.
929          climss?period=0 refers to constant field,
930          climss?period=-12 to monthly forcing
931      - split up namelists in data.exf
932    o pkg/seaice:
933      - remove seaice_exch and seaice_exch_uv
934      - remove superfluous exchange of theta
935      - add myThid to seaice_budget_ocean/ice
936      - add new interface for atmospheric wind forcing (C-grid only)
937        + new routine
938        + two new field (taux, tauy for stress over ice)
939        + removed one global field (DAIRN) for C-grid case only
940    o pkg/thsise
941      - 2nd set of modifs for thsice adjoint in conjunction with exf
942    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
943    
944    checkpoint58y_post
945    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
946      vertical diffusivity, similar to that in MOM4; turned on using
947      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
948      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
949    o Added capability for 3D specification of background vertical diffusion
950      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
951      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
952      "data" file that contains the 3D vertical diffusivity coefficients.
953    o ice dynamics (pkg/seaice) with thsice thermodynamics:
954      - add code within pkg thsice to advect & diffuse sea-ice fields
955      similar to (and will replace) what has been added in  seaice_advdiff.F,
956      but: - conserving Mass, Heat & Salt.
957           - better when using non-linear advection scheme (not yet fully tested)
958           - can also be used in atmospheric set-up (for now, only the diffusion).
959    
960    checkpoint58x_post
961    o IO option for global-file compact format:
962      - add options when generating topology (utils/exch2/matlab-topology-generator)
963      - add I/O capability (pkg/mdsio).
964      - adapt utils/matlab/rdmds.m to read this format.
965      for now long-line format not yet supported by pkg/mdsio (& exch2).
966    o shelfice: add a few diagnostics
967    
968    checkpoint58w_post
969    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
970      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
971      (and replace horiVertRatio in NH code).
972      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
973                         and tutorial_plume_on_slope (sensitive to truncation)
974    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
975      directly to drive seaice model (C-grid only)
976    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
977     - reintroduce computation of wind from stress,
978     - compute tau (in exf_bulkformulae.F) from windstress averaged to
979       mass points to avoid tau = 0
980     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
981    o rdmnc.m: make it work with "global" files created with gluemnc
982    o rdmnc.m : some improvements in dealing with singleton dimension
983      (tested on all testreport mnc output files).
984    o genmake2: disable pkg/profiles if netcdf test fails.
985    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
986    o move call to cal_readparms up to make calendar parameters/variable available
987      to all packages
988    
989    checkpoint58v_post
990    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
991      useDynP_inEos_Zc tested.
992  o pkg/exf: changes to properly interpolate/mask/scale initial fields  o pkg/exf: changes to properly interpolate/mask/scale initial fields
993  o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields  o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
994    and portions thereof.  See read_cs.txt for description and examples.    and portions thereof.  See read_cs.txt for description and examples.
