4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    checkpoint61i
8    o autodiff:
9      fix autodiff_sore/_restore indices for obcs
10      (spotted by I. Hoteit, M. Mazloff)
11    o pkg/autodiff, pkg/ctrl:
12      Add flag to reduce all tapelev I/O to single-prec.
13      In data.ctrl set
14        doSinglePrecTapelev = .TRUE.
15    o model/src/ini_curvilinear_grid.F: check in hack for SX8 compiler
16      to make sure that recip_dxV and recip_dyU are never zero, until we
17      have a proper exchange for them. Most compilers do not seem
18      to mind divisions by zero in the overlaps, as long as the results are
19      not used anywhere, but sxf90 does.
20    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
21      real fresh water flux (not yet)
22    o pkg/mdsio & rw:
23     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
24     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
25    o pkg/flt:
26     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
27       init_fixed & ini_varia.
28     - clean-up & simplify linear interpolation S/R:
29       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
30     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
31     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
32     - add vert. coordinate & horiz. indices to output files.
33     - change vertical position in initial condition, from index to depth [m].
34     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
35       (easier to get to a curvilinear grid) ; delX,delY no longer used.
36    o pkg/ggl90: a few modifications:
37     - fix bottom boundary condition, and interpolation of KappaE
38       near top and bottom
39     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
40     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
41     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
42    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
43      (maintain temporary backward compatibility, until next checkpoint)
44    
45    checkpoint61h
46    o pkg/diagnostics with "periodic averaging diagnostics":
47      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
48    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
49    o pkg/obcs: fix loop ranges for balancing code
50    o pkg/flt:
51     - improve criteria for finding which tile owns a float.
52     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
53    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
54      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
55      with ocean biogeo)
56    o pkg/flt:
57     - do some cleaning and fix the restart ;
58     - add output.txt in flt_example/results to get this pkg tested.
59    o genmake2: add an EXTENDED_SRC option and flag.
60       for now, cannot be turned on on command line (only through genmake_local)
61    o pkg/mdsio: read/write vector:
62     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
63     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
64       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
65     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
66      (drop to 4 digits matching for grad). But this test does not look very
67      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
68    
69    checkpoint61g
70    o pkg/flt:
71      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
72       + make OPTIONS file more standard.
73      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
74      - fix _BYTESWAPIO CPP-Flag
75      - standard reading of file-parameter "data.flt"
76      - fix argument list of S/R FLT_RESTART
77      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
78    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
79    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
80      a still unfixed compiler/optimization bug
81    
82    checkpoint61f
83    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
84      update results of global_ocean.cs32x15.icedyn test.
85    o move getcon.F from model/src to pkg/fizhi.
86    o pkg/exf: add parameter for extrapolation of temp up to the surface
87       and option to prevent negative evap (in bulk_largeyeager04 only).
88    o Prather Advection scheme: fix tracer conservation for divergent flow
89      (e.g., when using NonLin Free-Surface).
90    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
91    o gmredi (Visbeck-variable-K):
92     - add more parameters to Visbeck-variable-K.
93     - use a 5 points average for dSigmaR in Visbeck-K calculation
94       (more "homogenous": same stencil and same weights as in dSigmaH)
95     - update output of ideal_2D_oce experiment.
96    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
97      (#undef REAL4_IS_SLOW)
98     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
99       coordinate variable
100     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
101       (surface forcing fields), removes some of the functionality
102     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
103     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
104       probably not all: copy _RS surface flux fields to RL field before
105       calling DIAGNOSTICS_FILL
106     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
107       real*4 (CALL EXCH_*_RS) versions.
108     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
109       (generate new output).
110    
111    checkpoint61e
112    o gmredi (Visbeck-variable-K):
113      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
114      - change computation of Visbeck-K where Slope > Smax :        
115        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
116        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
117    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
118      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
119    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
120    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
121      does not become too large (to avoid precision problems in implicit-diffusion
122      solver); update ideal_2D_oce output.
123    o pkg ggl90:
124      - in ggl90_cal.F: compute only one set of visc/diff, used to
125        step forward TKE/T/S/momentum
126      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
127        have Prandlt =1)
128    o gmredi (fm07):
129      - add lower limit on Transition layer thickness + lower limit on 1/lambda
130      - allow to set few more params from data.gmredi
131    o pkg ggl90:
132          - add missing sqrt(2) factor in computation of mixing length
133            scale in ggl90_calc.F
134            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
135    
136    checkpoint61d
137    o adjoint modifs
138      - adapt to new field rhoInSitu
139      - allow to revert from StoreDynVars2D, StoreDynVars3D
140        to individual fields
141        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
142    o store 3-D (in-situ) density in commom block (DYNVARS.h)
143     - save 1 rho computation.
144     - no longer modify T & S inland when using down_slope pkg.
145    o gad_som : allow to switch to SOM advection for T & S without corresponding
146      pickup files (using new S/R: MDS_CHECK4FILE).
147    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
148      (for useSingleCpuIO to work in multi-threaded)
149    o pkg/shelfice:
150     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
151       with SHELFICEtopoFile in data.shelfice
152     - move code for reading ice shelf topography and modifying hFacC into separate
153       subroutines of the shelfice package
154     - separate initialisation of "fixed" and "variable" variables
155     - kTopC is not (yet) replaced by kSurfC, although this is possible
156    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
157    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
158      and rename:
159      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
160      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
161    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
162    
163    checkpoint61c
164    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
165      to add mass source/sink of fluid in the interior (3-D generalisation
166      of oceanic real-fresh water flux).
167    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
168    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
169    o new pkg: down_slope
170      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
171      - presently, modify T & S inland (dwnslp_calc_rho.F).
172        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
173      - implementation for ocean in P-coords not tested.
174      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
175    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
176      (to facilitate conversion of oceanic pkg to p-coordinate).
177    o change FIND_RHO to FIND_RHO_2D :
178      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
179    o new pkg: cheapaml
180    
181    checkpoint61b
182    o exch2:
183      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
184      - no longer depend on the order sequence (N,S,E,W).
185      - 3rd exchange no longer needed (tested with 24 tiles).
186      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
187      - exch_UV_A-grid readily available (but not yet tested).
188      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
189      (both are no longer needed) in exch_uv: no effect in forward run; but
190       get truncation error differences with adjoint exch.
191    o exch2:
192     - change index-bounds storage (moved from target to local tile,
193       more intuitive this way) ; rename/remove some variables.
194     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
195    
196    checkpoint61a
197    o exch2/matlab-topology-generator:
198      fix bug in index bounds for N-S internal exchange (hard to tell if this
199      had any effect on the solution).
200    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
201      is exceeded
202    o testreport: modify syntax of awk, so that it works also with
203      awk, and not only with nawk and gawk
204    
205    checkpoint61
206    o autodiff
207      Change default for TAF usage by removing argument '-nonew_arg'
208      This changes TAF subroutine argument list (ordering of active var.)
209      Omission of this flag leads to incompatibility w.r.t. TAMC
210      To restore TAMC-compatibility, need following modifs:
211      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
212      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
213      Tested TAF version is 1.9.22
214      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
215    
216    checkpoint60
217    --->>> This is the last checkpoint for which generating the adjoint
218    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
219    --->>> by default.
220    --->>> Future checkpoints will ommit this flag by default.
221    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
222    o pkg/grdchk: Add gradient check to etan0 perturbations.
223    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
224    o pkg/autodiff: more flexibility in zeroadj.
225      model/src: modifying do_oceanic_phys.F accordingly.
226    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
227    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
228      special setup of gmredi for which the adjoint is stable
229      enough for parameter optimization.
230    o bridging the gap between eddy stress and GM.
231      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
232          along with a change in CPP option (now ALLOW_EDDYPSI).
233      -> when using GM w/ GM_AdvForm:
234          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
235          is applied either in the tracer Eq. or in momentum Eq.
236          depending on data.gmredi (intro. GM_InMomAsStress).
237      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
238      The key modifications are in model/src/taueddy_external_forcing.F
239      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
240    
241    checkpoint59r
242    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
243      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
244      fix option to read coriolis(@ cell-corner) from files with CS-grid.
245    o pkg/mnc: add some attributes to standard 1D-coordinate variables
246    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
247      mass points, when using mnc for output
248      - add runtime parameter (missing_value, missing_value_int) to override
249        default (which is the value of getcon('UNDEF'))
250    o pkg/mnc: prepare mnc for the actual use of missing values with the
251      diagnostics package: small fix in mnc_cw_readwrite.template and more
252      initialisation of never used fields
253      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
254      versions
255    o pkg/thsice/thsice_ini_vars.F added default initial values so that
256      thermodynamics sea ice solver does not blow up when some initial fields
257      are missing.
258    o move from external_forcing_surf.F to ini_forcing.F
259      the p-coord. hack consisting in using pLoad to set phi0surf ;
260      update output of tutorial_global_oce_in_p (affected @ truncation level).
261    o Freshen up a bit hs94.1x64x5, notably:
262      remove rotationPeriod and tRef=5*0. (adjoint only), and add
263      exactConserv=.TRUE.
264    o pkg/generic_advdiff:
265      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
266      applies to files where Temperature & Salinity 2nd Order moments are used.
267    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
268      this uses a dynamically allocated internal state data structure
269      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
270      and requires a fortran 90 compiler
271    
272    checkpoint59q
273    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
274       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
275    o Refresh tutorial_global_oce_biogeo, notably:
276      - change bathymetry (put back seamounts in ACC, use hFacs)
277      - change EOS (POLY3 --> JMD95Z)
278      - use Bryan-Lewis vertical diffusivity
279      - use multidimensional advection
280      - remove old virtual virtual in dic pkg, now done through ptracer pkg
281      - change a couple of parameters in dic pkg
282    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
283    o pkg/obcs: change default to OBCSfixTopo = .true.,
284      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
285      - replace "debugMode" with "debugLevel .GE. debLevB"
286    o implementation of TAF directives for gchem,cfc,dic
287    o remove "exp5" (replaced by tutorial_deep_convection).
288    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
289      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
290      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
291      --> changes results in exp4, seaice_obcs
292    o tutorial_deep_convection :
293      update the set-up and increase resolution and domain size ; start
294      from pseudo initial conditions = output at t=120mn in order to see
295      something happening when running testreport.
296    o pkg/seaice: add os7mp as an advection scheme
297                  add check for advection schemes
298                  add a flag for restoring T and S underneath sea ice
299    o pkg/my82: add netcdf-support and diagnostics
300    o thsice pkg:
301      - Now hsMax limits snow height by turning it into ice following
302        flooding scheme (and now conserving energy)
303      - Slight rewriting of the formula in thsice_calc_thick.F
304      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
305      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
306    
307    checkpoint59p
308    o gchem / dic / cfc :
309      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
310      - add new parameter files: "data.dic" & "data.cfc" ;
311      - various re-arrangement in initialisation & header file ;
312      - fix tutorial_global_oce_biogeo for multi-threaded test.
313    o pkg/dic: test for "pickup_dic" file when restarting ;
314      if no pickup-file, can restart with a re-initialised pH (same as it did
315      before) providing pickupStrictlyMatch is set to False.
316    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
317      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
318    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
319      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
320    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
321     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
322       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
323    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
324       scheme to use for vorticty-term ;
325     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
326       (with default selectVortScheme, return to original discretisation)
327     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
328    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
329    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
330      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
331      also fix diagnostics VISCAHW & VISCA4W.
332    
333    checkpoint59o
334    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
335    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
336      move a few statemens out the main loop into separate loops
337    o pkg/shelfice:
338      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
339        (kg/m^2/s), does not break tests, because in verification/isomip,
340        rhoConstFresh=rhoConst (by accident)
341      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
342      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
343        new file model/src/seawater.F, so that they are available for all pkgs.
344      - convert potential temperature into in-situ temperature. This changes the
345        isomip tests => update tests
346    o add a flag writePickupAtEnd (default=true) to be able to suppress
347      writing a pickup at the last timestep
348    o tools/mpack-1.6 :
349      - disable automake (not working) and autoconf (not needed).
350      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
351        also cleaner with much less compilation warnings.
352    o pkg/profiles:
353      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
354      (for "less than 32 characters name" compiler requirement)
355    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
356      conditions that have a different sampling frequency than S/T/U/V obcs
357    o pkg/diagnostics (stats-diags):
358      - fix global Min/Max in case 1 processor get only empty tiles
359    o genmake2: replace (4 times)
360         make genmake_tc_1.o >> genmake_warnings 2>&1
361      with
362         COMM="$CC $CFLAGS -c genmake_tc_1.c"
363         echo $COMM >> genmake_warnings
364         $COMM >> genmake_warnings 2>&1
365      to make genmake2 always see the value of CC as specified in the optfile.
366    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
367      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
368      - modify verification advect_cs test to test SOM-advection on CS-grid.
369    o pkg/ctrl:
370      - Rewrite of ctrl_map_ini_ecco.F,
371        introducing a generic routine (ctrl_map_ini_gen.F).
372      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
373    
374    checkpoint59n
375    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
376      number in dedicate array "hdiag":
377      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
378        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
379      - many small changes (integer format) for large number of diagnostics
380      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
381        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
382    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
383      usingSphericalGrid, this allows to define the rotated grid coordinates
384      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
385      geographical coordinates according to the inverse of the rotation defined
386      by the Euler angles, so that Coriolis parameter and online-interpolation by
387      exf works with the geographical coordinates on XC/YC/XG/YG.
388      Naturally, this feature does not work with all packages, so some
389      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
390      profiles), because there the coordinates are assumed to be regular
391      spherical grid coordinates.
392    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
393      - introduce isopycnal diffusion coefficient control.
394    o tools/adjoint_options:
395      - additional control vector components.
396    o pkg/mnc: have mnc create marginally meaning full coordinate variables
397      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
398    o pkg/mypackage:
399      - add example of read/write pickup for state-var ;
400      - add entry points to the main code for state-vars diags & write-pickup.
401    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
402      transitions for useExfYearlyFields
403      - add new subroutine that determines the file to read from for
404        use*YearlyFields = .TRUE. and .FALSE.
405      - add a verification experiment to global_with_exf that tests
406        useExfYearlyFields with USE_EXF_INTERPOLATION defined
407    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
408      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
409      subroutines (which could be generated from a template, because they are
410      almost identical), for now they are included in obcs_prescribe_read.F for
411      simplicity
412    o pkg/exf:
413      - add a little more diagnostic to exf_interp_read (in analogy to
414        mds_read_field, can be turned off with debugLevel < debugLevA=1)
415      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
416        ugly but fast by unrolling short inner loops, inserting a unroll=8
417        directive in routine lagran, and splitting a loop and making do while the
418        outermost loop (the latter requires the intoduction of index arrays)
419    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
420    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
421      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
422    o verification/seaice_obcs: updated for restart test and latest options
423    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
424      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
425      for now this is only available for the C-grid code and also within
426      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
427    
428    checkpoint59m
429    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
430      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
431    o gad_som : fix flux output (& diagnostics) to have same units as other  
432      advection scheme fluxes (was previously multiplied by deltaT).  
433    o added verification/seaice_obcs both to test seaice open boundaries
434      and to provide an example matlab scrpt for generating them
435    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
436    o pkg/salt_plume: clean up salt_plume_frac.F to
437      remove redundancy in PlumeMethod 1 and 4
438    o pkg/kpp: added saltplume diagnostics
439    o pkg/obcs and pkg/seaice:
440      - do not set uice and vice to zero when OB*icefile are unspecified
441      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
442      - moved seaice tracer obcs after call to seaice_growth
443    o pkg/salt_plume: added various options for salt plume depth
444      criterion and for vertical distribution of the salt
445    
446    checkpoint59l
447    o pkg/ptracers: new version of ptracers pickup:
448      read meta file and write only fields which are needed to restart.
449      ( same logic as main pickup file ; also using pickupStrictlyMatch )
450    o pkg/seaice:
451      - add timescale for melting due to warm mixed layer as a means of
452        setting SEAICE_availHeatFrac more conveniently
453      - add a CPP-flag/runtime parameter check for flooding algorithm
454      - reformulated availHeat in seaice_growth.F to be independent of AREA
455    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
456      unit changes
457    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
458    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
459      SX vector computer.
460    o pkg/seaice:
461      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
462        seaice forcing fields can now be read only through pkg/exf
463      - removed some unused halos
464    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
465    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
466      or U/VICE from U/VWIND before computing U/VSTRESS
467    
468    checkpoint59k
469    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
470      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
471    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
472      all experiments pass when compile with un-initialised var. checking option.
473    o added pkg/salt_plume
474    o script to test restart (for now, in MITgcm_contrib/jmc_script)
475    o pkg/seaice: new read/write pickup version.
476      read meta file and write only fields which are needed to restart.
477      ( same logic as main pickup file ; also using pickupStrictlyMatch )
478    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
479    o lab_sea.hb87: modify the domain & update output.hb87.txt :
480      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
481      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
482      process. Fixed here by closing the domain at the Northern boundary.
483    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
484    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
485      a set of consecutive levels in/from a 3-D array.
486    o pkg/ptracers:
487      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
488      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
489    
490    checkpoint59j
491    o in pkgs: dic, obcs, offline, rbcs:
492      standard way to compute coeff. for time interpolation between 2 time reccords
493      which retains full precision (& make results less dependent on compiler).
494      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
495    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
496      packages instead of reading ice cover and wind speed separately
497    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
498     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
499      to allow to compile customized code before the update)
500    o cleaning-up:
501      - fix CPP instruction syntax in pkg/obcs
502      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
503        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
504      - fix some threads issue in IO parts.
505    o pkg/dic:
506      - add tons of "_d 0" (--> much better testreports !)
507       and then update outputs of tutorial_global_oce_biogeo
508    o pkg/mom_fluxform:
509      add a special version of momentum advection intended to conserve momentum
510      next to a bathymetry step or a coastline edge. (default = off = #undef)
511    o new read/write pickup version:
512      - for now, only implemented for main (mdsio) pickup file.
513      - write out only what is needed to restart; merge pickup_nh , pickup_ph
514        and main pickup together.
515      - read meta file; read only what is needed to restart; stop if a field
516        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
517        if it make sense (even if the restart is not perfect).
518      - if no meta file, assume that pickup to read corresponds exactly to
519        a pickup that would currently be written.
520      - read pickup written in the old format (until checkpoint59i) if it
521        recognizes an old meta file (no field-list).
522      - add a meta file in exp. which starts from a pickup: 2 cases:
523        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
524         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
525        b) a meta file describing the content of the associated pickup file
526         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
527    o pkg/mdsio & pkg/rw:
528      - new routine to read a meta file ; new set of routine to read
529        Multiple-fields file (with meta file).
530    o added open boundary conditions capability for seaice
531        HSNOW, HSALT, UICE, and VICE
532    
533    checkpoint59i
534    o adjoint:
535      * fix multiDimAdvection adjoint
536        (partial recomputation problem by TAF for fVerT(:,:,kDown)
537        and comlev1 size definition (maxpass vs. max. number of tracers)
538      * verification/global_ocean.90x45x15 adjoint now tests
539        NLFS and multiDimAdvection using DST3 (=30)
540      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
541    o pkg/kpp: add "_d 0" to real constant (if missing);
542      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
543      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
544    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
545      for internal parameters related to restart process (formerly from PARAMS.h)
546      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
547    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
548      as argument. (only atm2d & obcs write_pickup have not yet been updated)
549    o pkg/monitor:
550      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
551      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
552      - account for deep Atmosphere factor and density factor (anelastic)
553    o added open boundary conditions capability for seaice HEFF and AREA
554    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
555      thermodynamics
556      - requires a little reorganization, which affects the testreport results
557        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
558        so that now the conservative form is tested
559      - add a few comments
560    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
561    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
562    o add new diagnostics to seaice: advective, diffusive fluxes (only for
563      multidim-advection, for scheme 2 they are not filled) and transports,
564      thermodynamic growth rates
565    o change units of EmPmR (inside the code, + within coupling interface)
566      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
567      Affects results @ truncation level (cg2d match) and update output of
568       experiments: lab_sea(6), global_ocean.90x40x15(10),
569      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
570      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
571      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
572      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
573    
574    checkpoint59h
575    o pkg/exf:
576      - improve vectorization by moving if-statement out of loops in
577        exf_mapfields, exf_radiation
578      - exf_bulkformulae.F: introduce 2D fields and vectorize code
579    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
580    o testreport:
581      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
582        monitor & update offline_exf_seaice exp. output.
583      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
584    o pkg/seaice:
585      - bug fix in the evp solver: boundary conditions were affected be
586        masking of zMax/zMin (changes results)
587      - minor bug fix in boundary conditions in seaice_calc_strainrates
588        (changes results for no_slip)
589      - seaice_lsr.F: make interpolation of eta dependent on boundaries
590      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
591      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
592        stress formulation and no-slip boundary conditions
593    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
594      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
595    o pkg/seaice: a first HSALT time stepping equation has been checked in
596    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
597      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
598      without requiring DO-IF statements
599    o pkg/thsice:
600      use continuous power-law function for partition of energy between lateral
601      melting/freezing and thinning/thickening ; old code using step function
602      still available with #undef THSICE_FRACEN_POWERLAW
603      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
604    o testreport: change AD testing : check against results/output_adm.txt
605      using same scripts as for forward test.
606    
607    checkpoint59g
608    o adjoint testing: in preparation for changing testreport:
609      - output format: cost and grad written on separated lines
610      - ad output results in directory "results" (instead of "results_ad")
611    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
612    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
613    o pkg/ecco: allow user defined cost function contributions
614    o testreport:
615      Allow to choose (per experiment) the list of tested output variables
616       and the main variable (used to issue a pass/FAIL ) ;
617      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
618      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
619      Also modify printing of summary:
620       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
621       b) echo the list of tested variables in the individual summary.txt of
622          each experiment.
623    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
624      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
625      (but still depend on the tile decompostion of the domain).
626    o pkg/seaice: change a discretization detail to make the B-grid code
627      "more symmetric". This change is likely to remove all "ridges/leads" that
628      where quasi-aligned with the grid in B-grid solutions. It may also be
629      the solution to the stress coupling issues with the B-grid.
630    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
631      remove .cvsignore from input dir. (since testreport no longer run here).
632    o pkg/thsice:
633     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
634     - fix reshaping of sea-ice just after advection:
635       melt all the ice only if ice-volume is too small.
636     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
637       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
638     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
639    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
640      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
641    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
642      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
643      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
644      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
645      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
646      -> update output.txt
647    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
648     this affects truncation error: -> update output.txt of exp:
649      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
650      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
651    
652    checkpoint59f
653    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
654    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
655      a bounded range (in forward mode)
656    o pkg/ecco, ctrl, autodiff and mom_common:
657     internal parameter controls, completements of implementations
658    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
659    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
660      (not seem any difference in testing results).
661    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
662       at face corners.
663    o pkg/generic_advdiff:
664     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
665      loop range indices for computing vertical advection tendency
666      and do the calculation in the interior only (no overlap) ;
667      for now, only implemented for SOM advection (to save CPU time).
668     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
669    o exch2 adjoint
670      First set of changes:
671      - add exch2 hand-written adjoint templates
672      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
673        This will require cleanup in pkg/autodiff/*.F
674        (changed routines currently kept separate in verif. code/)
675      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
676        that used to hide exch2 or cubed-sphere specific code
677        (commented via 'cph-exch2')
678    o pkg/seaice
679      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
680    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
681       output of global_ocean.cs32x15.thsice .
682    
683    checkpoint59e
684    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
685      for B-grid vector (not yet tested) and C-grid vector (<- only used
686      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
687    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
688      (#ifdef ALLOW_SALT_PLUME)
689    o gather_2d/scatter_2d: removed halo regions
690    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
691      scheme and the corresponding test case (under front_relax dir). For now,
692      only available with Skew-flux form and not yet tested in realistic set-up.
693      adjoint: store directives updated, but gradient checks deteriorated,
694      so maybe GM/Redi adjoint is now broken.
695    o seaice adjoint
696      * add AREA, HEFF, HSNOW as control variable
697        (should not change lab_sea results)
698      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
699    o pkg/seaice:
700      * added computation of saltFlux in seaice_growth;
701        For time being, sea ice salinity is assumed constant
702        contribution of snow flooding to freshening of sea ice is neglected.
703        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
704        defaults to 0.0 in order to maintain backward compatibility.
705        Typical values for SEAICE_salinity are 4 to 10 g/kg.
706      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
707      * added SEAICE_availHeatFrac, which specifies fraction of surface level
708        heat content used to melt or grow ice
709      * commented out cap of HICE: it helps keep ice thinner
710      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
711      * applied OBCS T/S mask to HEFFM sea ice mask
712    
713    checkpoint59d
714    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
715     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
716     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
717    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
718     and change default value of parameter "GM_Small_Number";
719     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
720       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
721       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
722    o pkg/ecco: cost function when applying pkg/smooth to controls
723    o pkg/ctrl: add forcingPrecond run time parameter
724    o pkg/seaice:
725     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
726     - fix bug in metric terms of u-equation in LSR solver (implicit part),
727       changes verification/lab_sea
728     - rearrange implicit part of u-equation in LSR solver to make it easier to
729       read, understand, and debug. This causes changes at the truncation level.
730     - fix (serious) bug in the boundary conditions (sign error in the implicit
731       part) of the LSR solver. Changes all LSR results.
732     - fixed problem with HSNOW initialization to avoid thick snow when AREA
733       is initilized with small values - does not change lab_sea results.
734     - added HsnowFile initialization capability
735    o pkg/smooth: addition to model/src and pkg/ctrl so allow
736     initialization of pkg/smooth and application to control vector
737    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
738    o dependencies: pkg/profiles requires pkg/cal
739    o pkg/profiles:
740     - added option ALLOW_PROFILES_GENERICGRID
741         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
742         that interpolation information (grid points and coefficients) is provided
743         within the netcdf input files.
744         -> sample matlab scripts can be found in MITgcm_contrib/gael
745         that allow you to prepare netcdf input files.
746     - also modified: cleaner include statements, cleaner error print statements,
747       cleaner stops when error, and more tests of the netcdf input files consistency.
748    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
749    o pkg/seaice:
750     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
751       requires a new routine: seaice_diagnostics_fill.F
752     - make sure that seaice does not move if not forced (pressure replacement
753       method, Hibler and Ip, 1995), changes results
754     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
755     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
756       It is turned off by default (=-1.), because it changes the results.
757     - make it possible to read AREA from a file, too.
758    
759    checkpoint59c
760    o add S/R and diagnostics for oceanic mixed-layer depth
761    o move GMRedi call after all vertical mixing schemes (including KPP)
762    o pkg/thsice:
763     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
764      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
765    o pkg/obcs:
766     - bug fix for balance code
767    o pkg/seaice:
768      - allow values of SEAICE_elasticParm > 1
769      - add new parameter SEAICE_evpTauRelax as an alternative
770        to SEAICE_elasticParm
771      - make lsr boundary conditions free slip (by default), changes result
772      - add code for no slip boundary conditions for lsr
773      - set minimum of zeta to zero (and not 4e8) (changes results)
774      - add a cap on AREA after advecting AREA if seaice_growth is not called
775    o change calculation of Visbeck K:
776      - no longer depend on tapering scheme; instead, compute slope (limited
777        by GM_maxSlope). this is equivalent to what was comuted before with
778        clipping or linear tappering.
779      - fix vertical averaging (wrong by 1/2 level)
780      - leave the old version (but will not be maintained) within
781        #ifdef OLD_VISBECK_CALC / #endif
782      - update output of exp. ideal_2D_oce
783    o change error catch in calc_r_star to improve vectorization
784    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
785      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
786    o adjoint:
787      Re-organized adjoint checkpointing according to Matt Mazloff
788      (but with modifs/completions/cleanups)
789      Storing is now bundled into large arrays to optimized I/O
790      (and second step in cleanup of the_main_loop)
791    
792    checkpoint59b
793    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
794      - export/import (between ocean & coupler) fields needed for ocean DIC.
795    o pkg/seaice:
796      - get rid of three more exchanges seaice_calc_viscosities (required
797        different loop boundaries in seaice_lsr and seaice_ocean_stress)
798      - bug fix in seaice_ocean_stress (update of lab_sea required)
799      - reduce loop boundaries to necessary minimum also in seaice_evp
800      - go back to the old way of computing deltaC/Z as the adjoint likes that
801        better
802    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
803      passive tracer to an Age Tracer) + update output.txt
804    o pkg/exf:
805      - implement A-grid / C-grid selection for wind-stress input files.
806      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
807      for now, in exf_bulk_largeyeager04.F only :
808      - change implementation for case where windspeed + 2. components wind-stress
809        are read-in. AND use rhoConstFresh to convert evap.
810    o pkg/seaice:
811      - use correct EXCH_UV for wind-forcing (on A-grid).
812      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
813        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
814    o pkg/exf:
815      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
816      EXF_INTERPOLATION:
817      - merge global_with_exf/code version of exf_interp_read.F
818        to the main code ;
819      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
820        reading the file ; Important: This options needs to be defined to recover
821        previous code.
822        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
823      - no longer loose real*8 precision along the way when using exf_iprec=64.
824    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
825      - change discretisation of evp-solver in order to avoid another exchange
826        (changes lab_sea) and clean up a little
827      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
828        help the adjoint (this also changes the results slightly)
829      - add a few "_d 0" where they had been missing in seaice_evp.F
830      - cleaning up: remove unused seaice_calc_rhs.F
831    o pkg/exf: some cleaning-up:
832      - change various "constants" into runtime parameters
833      - cleaned-up Large&Yeager04 routine which should eventually
834        replace exf_bulkformulae.F (changed names of S/R and CPP)
835        and merged various ALLOW_ATM_WIND options
836     only used with thsice pkg (in thsice_get_exf.F):
837      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
838        which are used when useStabilityFct_overIce=TRUE (= the default)
839      - change default values of ice & snow emissivity and scale downward LW
840        by ice & snow emissivity.
841    o pkg/thsice:
842     fix few little problems, in thsice_calc_thickn.F:
843      - growth vertically (and not laterally) if iceFrac == iceMaskMax
844      - melt only laterally if hIce < hThinIce (as the comments say)
845      and in thsice_extend.F:
846      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
847      - start to form ice as soon as the minimum ice-volume is reachable.
848     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
849      and cpl_aim+ocn
850    o pkg/kpp
851     - move computation of surface related input fields to KPP into a new
852       subroutine kpp_forcing_surf.F
853     - remove wrong (within bi,bj loops) EXCH calls.
854     - little cleaning (add argument myThid in last position, cvs header ...)
855     - for now, fix conservation problem by exchanging KPPviscAz (may not
856       be the best fix)
857    o pkg/seaice
858     - check for inconsistent evp parameter/cpp-flag combination
859     - remove leftover errIO flat for obsolete name list error handling
860    o OpenAD
861     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
862    
863    checkpoint59a
864    o pkg/seaice: some parameter clarifications and a little bit of clean up
865    o pkg/thsice: rename run-time parameters:
866       himin       -> hIceMin
867       himin0      -> hThinIce
868       hihig       -> hThickIce
869       i0          -> i0swFrac
870       transCoef   -> bMeltCoef
871       frac_energy -> fracMelting
872      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
873       with default values (for now) that do not change the results.
874      remove old version of thsice vars advection in pkg/seaice.
875    o in FFIELDS.h:
876      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
877      - make pLoad & sIceLoad always available (but still only used if
878         ATMOSPHERIC_LOADING is #define).
879    o pkg/kpp: replaced _KPP_RL with _RL
880    o bug fixes for vertical diffusivity computations when both KPP and
881        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
882        are no longer updating the vertical diffusivity array
883        (passed as argument) but are (re-) setting those arrays.
884    o pkg/seaice: fix bug in evp solver, while doing that
885      - change (improve?) discretization of stress computations for both
886        cgrid-lsr and evp solver
887      - add a new routine to compute strain rates
888      - the above changes lab_sea results
889      - add no slip conditions for evp solver (off by default), lsr-version
890        may follow
891      - fix exchange for shear at Z-points (does not change lab_sea)
892      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
893        (to force the user to pick a time step since there is not "safe" way
894        of choosing it)
895      - add principal stress diagnostics
896      - rearrange fields for evp a little to avoid having to call a: too many
897        exchanges and b: exchanges for stress trensor components which we do
898        not have.
899      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
900        of evp, complete rewrite for lsr case (latter is does not yet work
901        in all cases)
902    o pkg/kpp: add code to have mixing in shelf ice caverns
903      - add myThid to all kpp routines (long overdue)
904    
905    checkpoint59
906    o pkg/exf:
907      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
908        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
909      - move exf header files from lower_case.h to UPPER_CASE.h ;
910        add missing cvs Header & Name
911      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
912      - add namelist param. selectStressGridPosition, exf_monFreq
913      - retire many _CLIM routines, and remove data.exf_clim
914        + params moved to data.exf
915        + climsst, climsss now handled by exf_set_gen, i.e.
916          climss?period=0 refers to constant field,
917          climss?period=-12 to monthly forcing
918      - split up namelists in data.exf
919    o pkg/seaice:
920      - remove seaice_exch and seaice_exch_uv
921      - remove superfluous exchange of theta
922      - add myThid to seaice_budget_ocean/ice
923      - add new interface for atmospheric wind forcing (C-grid only)
924        + new routine
925        + two new field (taux, tauy for stress over ice)
926        + removed one global field (DAIRN) for C-grid case only
927    o pkg/thsise
928      - 2nd set of modifs for thsice adjoint in conjunction with exf
929    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
930    
931    checkpoint58y_post
932    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
933      vertical diffusivity, similar to that in MOM4; turned on using
934      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
935      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
936    o Added capability for 3D specification of background vertical diffusion
937      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
938      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
939      "data" file that contains the 3D vertical diffusivity coefficients.
940    o ice dynamics (pkg/seaice) with thsice thermodynamics:
941      - add code within pkg thsice to advect & diffuse sea-ice fields
942      similar to (and will replace) what has been added in  seaice_advdiff.F,
943      but: - conserving Mass, Heat & Salt.
944           - better when using non-linear advection scheme (not yet fully tested)
945           - can also be used in atmospheric set-up (for now, only the diffusion).
946    
947    checkpoint58x_post
948    o IO option for global-file compact format:
949      - add options when generating topology (utils/exch2/matlab-topology-generator)
950      - add I/O capability (pkg/mdsio).
951      - adapt utils/matlab/rdmds.m to read this format.
952      for now long-line format not yet supported by pkg/mdsio (& exch2).
953    o shelfice: add a few diagnostics
954    
955    checkpoint58w_post
956    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
957      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
958      (and replace horiVertRatio in NH code).
959      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
960                         and tutorial_plume_on_slope (sensitive to truncation)
961    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
962      directly to drive seaice model (C-grid only)
963    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
964     - reintroduce computation of wind from stress,
965     - compute tau (in exf_bulkformulae.F) from windstress averaged to
966       mass points to avoid tau = 0
967     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
968    o rdmnc.m: make it work with "global" files created with gluemnc
969    o rdmnc.m : some improvements in dealing with singleton dimension
970      (tested on all testreport mnc output files).
971    o genmake2: disable pkg/profiles if netcdf test fails.
972    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
973    o move call to cal_readparms up to make calendar parameters/variable available
974      to all packages
975    
976    checkpoint58v_post
977    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
978      useDynP_inEos_Zc tested.
979    o pkg/exf: changes to properly interpolate/mask/scale initial fields
980    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
981      and portions thereof.  See read_cs.txt for description and examples.
982    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
983      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
984      following the great-circle arc between those 2 points.
985    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
986      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
987    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
988     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
989     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
990     - still needs work (not working with some options ; efficiency to improve)
991       and serious testing.
992     - use this scheme for temperature & salinity in 2 advection test exp.:
993       advect_xy & advect_xz, respectively.
994    
995    checkpoint58u_post
996    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
997    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
998    o testreport: add option "-skipdir" to skip some test.
999    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
1000      momentum calculation.
1001    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
1002    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
1003      remove checkpoint.F and the_correction_step.F (no longer used);
1004      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
1005    o add option (linFSConserveTr) to correct for tracer source/sink due to
1006      Linear Free surface
1007    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
1008    o pkg/thsice: fix reading mnc-pickups
1009    
1010    checkpoint58t_post
1011    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
1012    o pkg/mdsio:
1013     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
1014       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
1015       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
1016     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1017     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1018       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1019     - new S/R (to replace MDSWRITEMETA), which allows to write more
1020       informations (variable names, time ...) to meta files.
1021     - modify rdmds.m to give back the meta file content.
1022    o pkg/diagnostics: change vertical interpolation to be safer, and more
1023       flexible (define p-levels to interpolate to in data.diagnostics);
1024      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1025       diagnostic pointer.
1026    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1027    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1028    o fix multi-category seaice:
1029     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1030       SEAICE_MULTICATEGORY
1031     - fix short wave heat flux
1032    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1033       and allow to use EVP solver. Change forward lab_sea: test both EVP
1034       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1035    o Initial check-in of lab_sea adjoint
1036      (very similar to natl_box_adjoint/code_seaice)
1037      * used C-grid and EVP solver
1038      * used KPP, GM/Redi
1039      * uses inAdExact=.TRUE.
1040      * gradient checks fail for both ADM and TLM
1041        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1042        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1043        issue is related to forward mismatch between g77 an ifort
1044    o pkg/seaice: overhaul of thermodynamics
1045     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1046     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1047     - move a few global fields out of SEAICE.h into seaice_growth.F and
1048       make them 2D (FICE/QNETO/ ...)
1049     - remove FO (it is the same as QNETO)
1050     - introduce a few local fields to avoid modifying external fields such
1051       as atemp, etc.
1052    
1053    checkpoint58s_post
1054    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1055      changed exf_set_gen.F so that
1056        genperiod=0 means input file is one time-constant field and
1057        genperiod=-12 means input file contains 12 monthly means
1058    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1059      this affects truncation error ; generate new output file for exp. which
1060      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1061        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1062        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1063        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1064        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1065        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1066    o start implementation of deep-atmosphere and anelastic formulation
1067    o verification: remove 2nd copy of input files and use script "prepare_run"
1068      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1069    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1070    o profiles: fix for multithreaded case
1071    
1072    o diagnostics: rename few diags:
1073      s/'PRESSURE'/'RCENTER '/g
1074      s/'TICE    '/'oceFreez'/g
1075      s/'TAUX    '/'oceTAUX '/g
1076      s/'TAUY    '/'oceTAUY '/g
1077      s/'SWFLUX  '/'oceQsw  '/g
1078      s/DIFx/DFxE/g
1079      s/DIFy/DFyE/g
1080      and add few ocean-forcing diagnostics:
1081      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
1082    o modifications to pkg/seaice/growth.F and budget.F, which change results of
1083      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
1084      as actual snow thickness.  It now refers everywhere to effective snow
1085      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
1086    
1087    checkpoint58r_post
1088    o modifications to pkg/seaice/growth.F, which change results of
1089      lab_sea experiment: fixes pertain to melting snow over open water, to
1090      masking EVAP under sea ice, and to using the correct AREA variable for
1091      computations of EVAP, PRECIP, HSNOW, and GHEFF
1092    o add ability to read bathy, salt, and theta using MNC (off by def)
1093    o add flooding algorithm and advection of HSNOW for pkg/seaice;
1094      both are turned off by default and do no change any results
1095    o seaice advection with pkg/thsice: a step toward the use of non-linear
1096      advection scheme, but #ifdef or commented out for now (requires more EXCH).
1097    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
1098      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
1099      in natl_box (affects results @ truncation level: update output.txt)
1100    o multi-threading and IO:
1101      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
1102      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
1103        (needed to work with SingleCpuIO): tested in all verif. exp.
1104    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
1105      affects the results (but none of the verification test uses this scheme).
1106    o Adding some pkg/diagnostics capability to pkg/seaice
1107      (will certainly be subject to changes)
1108    o ctrl: adding new control variables:
1109      lwflux, lwdown, evap, snowprecip, apressure, runoff
1110    
1111    checkpoint58q_post
1112    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
1113      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
1114      high_res_cube configuration by 4% on Columbia.
1115    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
1116      add (in global_with_exf/code) a version of EXF_INTERP_READ without
1117      dynamical allocation (seems to work in multi-threaded).
1118    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
1119      single CPU io) so that TAF does not have to see EESUPPORT.h
1120    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
1121    
1122    checkpoint58p_post
1123    o obcs: stop if obcs is used with useCDscheme = .true.
1124    o shelfice:
1125     - fix a sign error so that no slip at shelfice interface works
1126     - remove stop for combination non-hydrostatic code and shelfice. That does
1127       not mean, that the results are correct, but at least they are numerically
1128       stable
1129    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
1130    o added adjoint exch routined for all exch*3d* routines
1131      and updated flow directives
1132    
1133    checkpoint58o_post
1134    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
1135      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
1136    o change controling S/R for writing pickup file (new S/R do_write_pickup)
1137      and clean-up reading/writing of pickup files.
1138    o fix local version of read/write pickup (NH part) in rotating_tank/code
1139    o simplify EXCH interface:
1140     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1141     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1142    o added the regrid package
1143    o shelfice:
1144     - add a simple boundary layer scheme to reduce noise
1145     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1146    
1147    checkpoint58n_post
1148    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1149       local variable (not in common block).
1150    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1151      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1152      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1153        to work with SingleCpuIO.
1154    o add "_d 0" to real constant of pkg/cfc subroutines ;
1155       update exp. cfc_exemple & tutorial_cfc_offline output files.
1156    o multi-threading and IO:
1157      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1158        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1159      - barrier before and after reading.
1160      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1161      - avoid using MDS_WRITELOCAL for LAND pkg output.
1162      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1163        common-block variables ; Allows multi-threading with master-thread IO.
1164    o change default MAX_NO_THREADS from 32 to 4 ;
1165      and stop cleanly when MAX_NO_THREADS is too small.
1166    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1167    
1168    checkpoint58m_post
1169    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1170       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1171    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1172       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1173       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1174    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1175        add MITgcm_tutorials (= code + all the tutorials)
1176    o ecco, option to compute cost for total ssh (mean+anom)
1177    o consistent with addition of ptracer and ssh in pkg/profiles
1178    o profiles: adding ptracer and ssh
1179    o testreport: change multi-test output-file name
1180      (from output.txt.{name} to output.{name}.txt)
1181    o profiles: now ok for mutli-tiles case
1182    o seaice: add 4 parameters for different advection schemes for area,
1183      (effective) seaice thickness, enthalphy, and snow height. Their default
1184      is the standard parameter SEAICEadvScheme
1185    o calc_gw:
1186     - add cosFacU in zonal viscous flux (harmonic.visc.).
1187     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1188       of tutorial_plume_on_slope.
1189    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1190    o calc_gw: true flux-form, account for horizontal grid spacing.
1191      update rotating_tank results, but not plume_on_slope (affected at
1192      truncation level, 11 digits).
1193    
1194    checkpoint58l_post
1195    o calc_gw:
1196     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1197     - remove side-drag for now (need to fix it); update plume_on_slope results.
1198     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
1199    o commit code to make SST/SSS weights spatially variable
1200      (based on either variable in-situ or variable initial T/S weights)
1201    o pkg/ecco:
1202      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
1203        now based on horizontally varying weights wthetaLev, wsaltLev
1204      * cost_averagesflags now returns year indices in addition to day, month
1205      * sflux balance is performed on annual basis
1206        (sflxumm, sfluxmm2, bal_sfluxmm)
1207      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
1208        including separate counting and multipliers
1209    o pkg/rbcs
1210      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
1211    
1212    checkpoint58k_post
1213    o testreport:
1214     - always build in dir. "build" (if not there, mkdir build instead of building
1215       & running in input)
1216     - run in dir run (if it exists), in build otherwise.
1217     - call prepare_run (if input/prepare_run exists)
1218     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1219    o pkg/exf modifications to interpolation and rotation routines for more
1220       reasonable treatment of North Pole singularity: for tracers North Pole
1221       value is set to northernmost zonal-mean value, for zonal velocity it is
1222       set to zero, and for meridional velocity it is set to northernmost value.
1223    o pkg/exf/exf_check_range.F
1224     - add tile index to diagnostics and move stop statement to the very
1225       end of the routine.
1226    o pkg/diagnostics: (diagnostics_main_init.F)
1227      define title of isomorphic variables according to the current config.
1228    o pkg/thsice with pkg/seaice dynamics:
1229    - fix domain of computation (interior only, required for exf) and do exchanges
1230    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1231    o towards a standard way of dealing with multi-threading in MONITOR
1232      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1233    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1234       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1235    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1236    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1237    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1238       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1239    o tracer advection:
1240     - clean-up and simplify calc_common_factors.F
1241     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1242       advection subroutine (but still not used within DST advection S/R)
1243    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1244    
1245    checkpoint58j_post
1246    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1247      from file (collects calls previously in FORWARD_STEP)
1248    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1249    o adjoint store dir. adjusted accordingly
1250    o genmake2
1251      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1252    
1253    checkpoint58i_post
1254    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1255      on wind stress (SEAICEstressFactor defaults to 1.)
1256    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1257      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1258    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1259      on CS-grid: no longer loosing mass.
1260    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1261    o pkg/ggl90: fix sloppy output and fix a bug
1262    o pkg/seaice: added SEAICEuseEVPpickup parameter
1263      - Set to false in order to start EVP solver with
1264        non-EVP pickup files when using SEAICEuseEVP
1265      - fix sign error in diffusion in seaice_calc_rhs
1266    
1267    checkpoint58h_post
1268    * Modifications for bottom topography control
1269      o replace hFacC by _hFacC at various places
1270      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1271      o add non-self-adjoint cg2d_nsa
1272      o update autodiff support routines
1273      o re-initialise hfac after ctrl_depth_ini
1274      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1275    * Adding verification for 5x5 box (4-layer) bottom topography control
1276    
1277    checkpoint58g_post
1278    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1279       used for mean seasonal cycle, mean diurnal cycle); add an example
1280       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1281    o pkg/ggl90:
1282      - add parameter (minimum surface kinetic energy)
1283      - fix bug (avoiding division by zero)
1284    o couple pkg/thsice to pkg/seaice:
1285      - modify advection in seaice to accomodate new scalar fields to be advected
1286      - only muliDimAdection scheme work with seaice/thsice
1287      - mapping of thsice-variables to seaice-variables, back and forth
1288      - does not break the verification experiments, but does not give the
1289        desired results either
1290    o pkg/seaice
1291      - make (default) second order advection a bit less confusing?
1292    
1293    checkpoint58f_post
1294    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1295      to pkg/seaice):
1296      - new routines thsice_map_exf and thsice_get_exf provide the interface
1297      - add an additional formal parameter to thsice_solve4temp
1298    o pkg/exf:
1299      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1300      - correct Stefan-Boltzmann constant
1301      - new parameter for longwave surface emittance
1302      - separate some stuff from exf_bulkformulae into new routines  
1303        exf_radiation, exf_wind
1304      - add new parameters and constants: longwave emissivity for ocean, ice
1305        and snow, evaporation parameters over ice
1306      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1307        either wind from stress or stress from wind
1308    o pkg/thSIce:
1309    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1310    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1311       and THSICE_CALC_THICKN
1312    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1313    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1314      to make debugging easier.
1315    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1316    o pkg/bulk_force:
1317      - clean-up comments and parameters ;
1318      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1319    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1320      generate new output for test-experiment: aim.5l_cs.thSI
1321    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1322      testreport accordingly
1323    
1324    checkpoint58e_post
1325    o SEAICE_CGRID adjoint done
1326    o R_STAR adjoint implemented.
1327      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1328      * need to sort out init. of h0facc, etc.
1329    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1330      to be able to use it in pure forward.
1331    
1332    checkpoint58d_post
1333    o upgrade simple test-experiment to tutorial example:
1334     step.1: duplicate the experiment and (step.2) will remove the old copy.

1357      me to turn off the excessive output to STDOUT that this package produces
1358    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1359      and add those terms in Vector-Invariant formulation.
