# Line 4  $Name$ Line 4  $Name$
4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o adding precip control xx_precip  o pkg/exf: add capability to bypass interpolation for runoff
8  o moved ptracer ctrl index 17 -> 32    by setting yet another CPP-flag
9    o autodiff
10      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
11      allows to switch to single-prec common blocks;
12      corresponding switch occurs in tamc.h, integer isbyte
13      TAF store directivs "byte" and "kind" seem equivalent;
14      Most tamc.h have been updated correspondingly.
15    
16    checkpoint61i
17    o autodiff:
18      fix autodiff_sore/_restore indices for obcs
19      (spotted by I. Hoteit, M. Mazloff)
20    o pkg/autodiff, pkg/ctrl:
21      Add flag to reduce all tapelev I/O to single-prec.
22      In data.ctrl set
23        doSinglePrecTapelev = .TRUE.
24    o model/src/ini_curvilinear_grid.F: check in hack for SX8 compiler
25      to make sure that recip_dxV and recip_dyU are never zero, until we
26      have a proper exchange for them. Most compilers do not seem
27      to mind divisions by zero in the overlaps, as long as the results are
28      not used anywhere, but sxf90 does.
29    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
30      real fresh water flux (not yet)
31    o pkg/mdsio & rw:
32     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
33     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
34    o pkg/flt:
35     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
36       init_fixed & ini_varia.
37     - clean-up & simplify linear interpolation S/R:
38       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
39     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
40     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
41     - add vert. coordinate & horiz. indices to output files.
42     - change vertical position in initial condition, from index to depth [m].
43     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
44       (easier to get to a curvilinear grid) ; delX,delY no longer used.
45    o pkg/ggl90: a few modifications:
46     - fix bottom boundary condition, and interpolation of KappaE
47       near top and bottom
48     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
49     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
50     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
51    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
52      (maintain temporary backward compatibility, until next checkpoint)
53    
54    checkpoint61h
55    o pkg/diagnostics with "periodic averaging diagnostics":
56      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
57    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
58    o pkg/obcs: fix loop ranges for balancing code
59    o pkg/flt:
60     - improve criteria for finding which tile owns a float.
61     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
62    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
63      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
64      with ocean biogeo)
65    o pkg/flt:
66     - do some cleaning and fix the restart ;
67     - add output.txt in flt_example/results to get this pkg tested.
68    o genmake2: add an EXTENDED_SRC option and flag.
69       for now, cannot be turned on on command line (only through genmake_local)
70    o pkg/mdsio: read/write vector:
71     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
72     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
73       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
74     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
75      (drop to 4 digits matching for grad). But this test does not look very
76      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
77    
78    checkpoint61g
79    o pkg/flt:
80      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
81       + make OPTIONS file more standard.
82      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
83      - fix _BYTESWAPIO CPP-Flag
84      - standard reading of file-parameter "data.flt"
85      - fix argument list of S/R FLT_RESTART
86      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
87    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
88    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
89      a still unfixed compiler/optimization bug
90    
91    checkpoint61f
92    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
93      update results of global_ocean.cs32x15.icedyn test.
94    o move getcon.F from model/src to pkg/fizhi.
95    o pkg/exf: add parameter for extrapolation of temp up to the surface
96       and option to prevent negative evap (in bulk_largeyeager04 only).
97    o Prather Advection scheme: fix tracer conservation for divergent flow
98      (e.g., when using NonLin Free-Surface).
99    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
100    o gmredi (Visbeck-variable-K):
101     - add more parameters to Visbeck-variable-K.
102     - use a 5 points average for dSigmaR in Visbeck-K calculation
103       (more "homogenous": same stencil and same weights as in dSigmaH)
104     - update output of ideal_2D_oce experiment.
105    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
106      (#undef REAL4_IS_SLOW)
107     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
108       coordinate variable
109     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
110       (surface forcing fields), removes some of the functionality
111     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
112     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
113       probably not all: copy _RS surface flux fields to RL field before
114       calling DIAGNOSTICS_FILL
115     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
116       real*4 (CALL EXCH_*_RS) versions.
117     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
118       (generate new output).
119    
120    checkpoint61e
121    o gmredi (Visbeck-variable-K):
122      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
123      - change computation of Visbeck-K where Slope > Smax :        
124        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
125        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
126    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
127      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
128    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
129    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
130      does not become too large (to avoid precision problems in implicit-diffusion
131      solver); update ideal_2D_oce output.
132    o pkg ggl90:
133      - in ggl90_cal.F: compute only one set of visc/diff, used to
134        step forward TKE/T/S/momentum
135      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
136        have Prandlt =1)
137    o gmredi (fm07):
138      - add lower limit on Transition layer thickness + lower limit on 1/lambda
139      - allow to set few more params from data.gmredi
140    o pkg ggl90:
141          - add missing sqrt(2) factor in computation of mixing length
142            scale in ggl90_calc.F
143            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
144    
145    checkpoint61d
146    o adjoint modifs
147      - adapt to new field rhoInSitu
148      - allow to revert from StoreDynVars2D, StoreDynVars3D
149        to individual fields
150        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
151    o store 3-D (in-situ) density in commom block (DYNVARS.h)
152     - save 1 rho computation.
153     - no longer modify T & S inland when using down_slope pkg.
154    o gad_som : allow to switch to SOM advection for T & S without corresponding
155      pickup files (using new S/R: MDS_CHECK4FILE).
156    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
157      (for useSingleCpuIO to work in multi-threaded)
158    o pkg/shelfice:
159     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
160       with SHELFICEtopoFile in data.shelfice
161     - move code for reading ice shelf topography and modifying hFacC into separate
162       subroutines of the shelfice package
163     - separate initialisation of "fixed" and "variable" variables
164     - kTopC is not (yet) replaced by kSurfC, although this is possible
165    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
166    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
167      and rename:
168      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
169      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
170    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
171    
172    checkpoint61c
173    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
174      to add mass source/sink of fluid in the interior (3-D generalisation
175      of oceanic real-fresh water flux).
176    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
177    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
178    o new pkg: down_slope
179      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
180      - presently, modify T & S inland (dwnslp_calc_rho.F).
181        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
182      - implementation for ocean in P-coords not tested.
183      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
184    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
185      (to facilitate conversion of oceanic pkg to p-coordinate).
186    o change FIND_RHO to FIND_RHO_2D :
187      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
188    o new pkg: cheapaml
189    
190    checkpoint61b
191    o exch2:
192      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
193      - no longer depend on the order sequence (N,S,E,W).
194      - 3rd exchange no longer needed (tested with 24 tiles).
195      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
196      - exch_UV_A-grid readily available (but not yet tested).
197      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
198      (both are no longer needed) in exch_uv: no effect in forward run; but
199       get truncation error differences with adjoint exch.
200    o exch2:
201     - change index-bounds storage (moved from target to local tile,
202       more intuitive this way) ; rename/remove some variables.
203     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
204    
205    checkpoint61a
206    o exch2/matlab-topology-generator:
207      fix bug in index bounds for N-S internal exchange (hard to tell if this
208      had any effect on the solution).
209    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
210      is exceeded
211    o testreport: modify syntax of awk, so that it works also with
212      awk, and not only with nawk and gawk
213    
214    checkpoint61
215    o autodiff
216      Change default for TAF usage by removing argument '-nonew_arg'
217      This changes TAF subroutine argument list (ordering of active var.)
218      Omission of this flag leads to incompatibility w.r.t. TAMC
219      To restore TAMC-compatibility, need following modifs:
220      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
221      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
222      Tested TAF version is 1.9.22
223      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
224    
225    checkpoint60
226    --->>> This is the last checkpoint for which generating the adjoint
227    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
228    --->>> by default.
229    --->>> Future checkpoints will ommit this flag by default.
230    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
231    o pkg/grdchk: Add gradient check to etan0 perturbations.
232    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
233    o pkg/autodiff: more flexibility in zeroadj.
234      model/src: modifying do_oceanic_phys.F accordingly.
235    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
236    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
237      special setup of gmredi for which the adjoint is stable
238      enough for parameter optimization.
239    o bridging the gap between eddy stress and GM.
240      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
241          along with a change in CPP option (now ALLOW_EDDYPSI).
242      -> when using GM w/ GM_AdvForm:
243          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
244          is applied either in the tracer Eq. or in momentum Eq.
245          depending on data.gmredi (intro. GM_InMomAsStress).
246      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
247      The key modifications are in model/src/taueddy_external_forcing.F
248      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
249    
250    checkpoint59r
251    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
252      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
253      fix option to read coriolis(@ cell-corner) from files with CS-grid.
254    o pkg/mnc: add some attributes to standard 1D-coordinate variables
255    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
256      mass points, when using mnc for output
257      - add runtime parameter (missing_value, missing_value_int) to override
258        default (which is the value of getcon('UNDEF'))
259    o pkg/mnc: prepare mnc for the actual use of missing values with the
260      diagnostics package: small fix in mnc_cw_readwrite.template and more
261      initialisation of never used fields
262      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
263      versions
264    o pkg/thsice/thsice_ini_vars.F added default initial values so that
265      thermodynamics sea ice solver does not blow up when some initial fields
266      are missing.
267    o move from external_forcing_surf.F to ini_forcing.F
268      the p-coord. hack consisting in using pLoad to set phi0surf ;
269      update output of tutorial_global_oce_in_p (affected @ truncation level).
270    o Freshen up a bit hs94.1x64x5, notably:
271      remove rotationPeriod and tRef=5*0. (adjoint only), and add
272      exactConserv=.TRUE.
273    o pkg/generic_advdiff:
274      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
275      applies to files where Temperature & Salinity 2nd Order moments are used.
276    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
277      this uses a dynamically allocated internal state data structure
278      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
279      and requires a fortran 90 compiler
280    
281    checkpoint59q
282    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
283       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
284    o Refresh tutorial_global_oce_biogeo, notably:
285      - change bathymetry (put back seamounts in ACC, use hFacs)
286      - change EOS (POLY3 --> JMD95Z)
287      - use Bryan-Lewis vertical diffusivity
288      - use multidimensional advection
289      - remove old virtual virtual in dic pkg, now done through ptracer pkg
290      - change a couple of parameters in dic pkg
291    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
292    o pkg/obcs: change default to OBCSfixTopo = .true.,
293      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
294      - replace "debugMode" with "debugLevel .GE. debLevB"
295    o implementation of TAF directives for gchem,cfc,dic
296    o remove "exp5" (replaced by tutorial_deep_convection).
297    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
298      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
299      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
300      --> changes results in exp4, seaice_obcs
301    o tutorial_deep_convection :
302      update the set-up and increase resolution and domain size ; start
303      from pseudo initial conditions = output at t=120mn in order to see
304      something happening when running testreport.
305    o pkg/seaice: add os7mp as an advection scheme
306                  add check for advection schemes
307                  add a flag for restoring T and S underneath sea ice
308    o pkg/my82: add netcdf-support and diagnostics
309    o thsice pkg:
310      - Now hsMax limits snow height by turning it into ice following
311        flooding scheme (and now conserving energy)
312      - Slight rewriting of the formula in thsice_calc_thick.F
313      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
314      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
315    
316    checkpoint59p
317    o gchem / dic / cfc :
318      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
319      - add new parameter files: "data.dic" & "data.cfc" ;
320      - various re-arrangement in initialisation & header file ;
321      - fix tutorial_global_oce_biogeo for multi-threaded test.
322    o pkg/dic: test for "pickup_dic" file when restarting ;
323      if no pickup-file, can restart with a re-initialised pH (same as it did
324      before) providing pickupStrictlyMatch is set to False.
325    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
326      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
327    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
328      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
329    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
330     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
331       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
332    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
333       scheme to use for vorticty-term ;
334     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
335       (with default selectVortScheme, return to original discretisation)
336     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
337    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
338    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
339      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
340      also fix diagnostics VISCAHW & VISCA4W.
341    
342    checkpoint59o
343    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
344    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
345      move a few statemens out the main loop into separate loops
346    o pkg/shelfice:
347      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
348        (kg/m^2/s), does not break tests, because in verification/isomip,
349        rhoConstFresh=rhoConst (by accident)
350      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
351      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
352        new file model/src/seawater.F, so that they are available for all pkgs.
353      - convert potential temperature into in-situ temperature. This changes the
354        isomip tests => update tests
355    o add a flag writePickupAtEnd (default=true) to be able to suppress
356      writing a pickup at the last timestep
357    o tools/mpack-1.6 :
358      - disable automake (not working) and autoconf (not needed).
359      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
360        also cleaner with much less compilation warnings.
361    o pkg/profiles:
362      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
363      (for "less than 32 characters name" compiler requirement)
364    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
365      conditions that have a different sampling frequency than S/T/U/V obcs
366    o pkg/diagnostics (stats-diags):
367      - fix global Min/Max in case 1 processor get only empty tiles
368    o genmake2: replace (4 times)
369         make genmake_tc_1.o >> genmake_warnings 2>&1
370      with
371         COMM="$CC $CFLAGS -c genmake_tc_1.c"
372         echo $COMM >> genmake_warnings
373         $COMM >> genmake_warnings 2>&1
374      to make genmake2 always see the value of CC as specified in the optfile.
375    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
376      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
377      - modify verification advect_cs test to test SOM-advection on CS-grid.
378    o pkg/ctrl:
379      - Rewrite of ctrl_map_ini_ecco.F,
380        introducing a generic routine (ctrl_map_ini_gen.F).
381      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
382    
383    checkpoint59n
384    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
385      number in dedicate array "hdiag":
386      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
387        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
388      - many small changes (integer format) for large number of diagnostics
389      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
390        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
391    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
392      usingSphericalGrid, this allows to define the rotated grid coordinates
393      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
394      geographical coordinates according to the inverse of the rotation defined
395      by the Euler angles, so that Coriolis parameter and online-interpolation by
396      exf works with the geographical coordinates on XC/YC/XG/YG.
397      Naturally, this feature does not work with all packages, so some
398      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
399      profiles), because there the coordinates are assumed to be regular
400      spherical grid coordinates.
401    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
402      - introduce isopycnal diffusion coefficient control.
403    o tools/adjoint_options:
404      - additional control vector components.
405    o pkg/mnc: have mnc create marginally meaning full coordinate variables
406      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
407    o pkg/mypackage:
408      - add example of read/write pickup for state-var ;
409      - add entry points to the main code for state-vars diags & write-pickup.
410    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
411      transitions for useExfYearlyFields
412      - add new subroutine that determines the file to read from for
413        use*YearlyFields = .TRUE. and .FALSE.
414      - add a verification experiment to global_with_exf that tests
415        useExfYearlyFields with USE_EXF_INTERPOLATION defined
416    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
417      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
418      subroutines (which could be generated from a template, because they are
419      almost identical), for now they are included in obcs_prescribe_read.F for
420      simplicity
421    o pkg/exf:
422      - add a little more diagnostic to exf_interp_read (in analogy to
423        mds_read_field, can be turned off with debugLevel < debugLevA=1)
424      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
425        ugly but fast by unrolling short inner loops, inserting a unroll=8
426        directive in routine lagran, and splitting a loop and making do while the
427        outermost loop (the latter requires the intoduction of index arrays)
428    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
429    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
430      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
431    o verification/seaice_obcs: updated for restart test and latest options
432    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
433      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
434      for now this is only available for the C-grid code and also within
435      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
436    
437    checkpoint59m
438    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
439      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
440    o gad_som : fix flux output (& diagnostics) to have same units as other  
441      advection scheme fluxes (was previously multiplied by deltaT).  
442    o added verification/seaice_obcs both to test seaice open boundaries
443      and to provide an example matlab scrpt for generating them
444    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
445    o pkg/salt_plume: clean up salt_plume_frac.F to
446      remove redundancy in PlumeMethod 1 and 4
447    o pkg/kpp: added saltplume diagnostics
448    o pkg/obcs and pkg/seaice:
449      - do not set uice and vice to zero when OB*icefile are unspecified
450      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
451      - moved seaice tracer obcs after call to seaice_growth
452    o pkg/salt_plume: added various options for salt plume depth
453      criterion and for vertical distribution of the salt
454    
455    checkpoint59l
456    o pkg/ptracers: new version of ptracers pickup:
457      read meta file and write only fields which are needed to restart.
458      ( same logic as main pickup file ; also using pickupStrictlyMatch )
459    o pkg/seaice:
460      - add timescale for melting due to warm mixed layer as a means of
461        setting SEAICE_availHeatFrac more conveniently
462      - add a CPP-flag/runtime parameter check for flooding algorithm
463      - reformulated availHeat in seaice_growth.F to be independent of AREA
464    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
465      unit changes
466    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
467    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
468      SX vector computer.
469    o pkg/seaice:
470      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
471        seaice forcing fields can now be read only through pkg/exf
472      - removed some unused halos
473    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
474    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
475      or U/VICE from U/VWIND before computing U/VSTRESS
476    
477    checkpoint59k
478    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
479      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
480    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
481      all experiments pass when compile with un-initialised var. checking option.
482    o added pkg/salt_plume
483    o script to test restart (for now, in MITgcm_contrib/jmc_script)
484    o pkg/seaice: new read/write pickup version.
485      read meta file and write only fields which are needed to restart.
486      ( same logic as main pickup file ; also using pickupStrictlyMatch )
487    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
488    o lab_sea.hb87: modify the domain & update output.hb87.txt :
489      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
490      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
491      process. Fixed here by closing the domain at the Northern boundary.
492    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
493    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
494      a set of consecutive levels in/from a 3-D array.
495    o pkg/ptracers:
496      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
497      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
498    
499    checkpoint59j
500    o in pkgs: dic, obcs, offline, rbcs:
501      standard way to compute coeff. for time interpolation between 2 time reccords
502      which retains full precision (& make results less dependent on compiler).
503      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
504    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
505      packages instead of reading ice cover and wind speed separately
506    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
507     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
508      to allow to compile customized code before the update)
509    o cleaning-up:
510      - fix CPP instruction syntax in pkg/obcs
511      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
512        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
513      - fix some threads issue in IO parts.
514    o pkg/dic:
515      - add tons of "_d 0" (--> much better testreports !)
516       and then update outputs of tutorial_global_oce_biogeo
517    o pkg/mom_fluxform:
518      add a special version of momentum advection intended to conserve momentum
519      next to a bathymetry step or a coastline edge. (default = off = #undef)
520    o new read/write pickup version:
521      - for now, only implemented for main (mdsio) pickup file.
522      - write out only what is needed to restart; merge pickup_nh , pickup_ph
523        and main pickup together.
524      - read meta file; read only what is needed to restart; stop if a field
525        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
526        if it make sense (even if the restart is not perfect).
527      - if no meta file, assume that pickup to read corresponds exactly to
528        a pickup that would currently be written.
529      - read pickup written in the old format (until checkpoint59i) if it
530        recognizes an old meta file (no field-list).
531      - add a meta file in exp. which starts from a pickup: 2 cases:
532        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
533         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
534        b) a meta file describing the content of the associated pickup file
535         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
536    o pkg/mdsio & pkg/rw:
537      - new routine to read a meta file ; new set of routine to read
538        Multiple-fields file (with meta file).
539    o added open boundary conditions capability for seaice
540        HSNOW, HSALT, UICE, and VICE
541    
542    checkpoint59i
543    o adjoint:
544      * fix multiDimAdvection adjoint
545        (partial recomputation problem by TAF for fVerT(:,:,kDown)
546        and comlev1 size definition (maxpass vs. max. number of tracers)
547      * verification/global_ocean.90x45x15 adjoint now tests
548        NLFS and multiDimAdvection using DST3 (=30)
549      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
550    o pkg/kpp: add "_d 0" to real constant (if missing);
551      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
552      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
553    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
554      for internal parameters related to restart process (formerly from PARAMS.h)
555      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
556    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
557      as argument. (only atm2d & obcs write_pickup have not yet been updated)
558    o pkg/monitor:
559      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
560      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
561      - account for deep Atmosphere factor and density factor (anelastic)
562    o added open boundary conditions capability for seaice HEFF and AREA
563    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
564      thermodynamics
565      - requires a little reorganization, which affects the testreport results
566        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
567        so that now the conservative form is tested
568      - add a few comments
569    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
570    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
571    o add new diagnostics to seaice: advective, diffusive fluxes (only for
572      multidim-advection, for scheme 2 they are not filled) and transports,
573      thermodynamic growth rates
574    o change units of EmPmR (inside the code, + within coupling interface)
575      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
576      Affects results @ truncation level (cg2d match) and update output of
577       experiments: lab_sea(6), global_ocean.90x40x15(10),
578      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
579      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
580      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
581      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
582    
583    checkpoint59h
584    o pkg/exf:
585      - improve vectorization by moving if-statement out of loops in
586        exf_mapfields, exf_radiation
587      - exf_bulkformulae.F: introduce 2D fields and vectorize code
588    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
589    o testreport:
590      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
591        monitor & update offline_exf_seaice exp. output.
592      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
593    o pkg/seaice:
594      - bug fix in the evp solver: boundary conditions were affected be
595        masking of zMax/zMin (changes results)
596      - minor bug fix in boundary conditions in seaice_calc_strainrates
597        (changes results for no_slip)
598      - seaice_lsr.F: make interpolation of eta dependent on boundaries
599      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
600      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
601        stress formulation and no-slip boundary conditions
602    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
603      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
604    o pkg/seaice: a first HSALT time stepping equation has been checked in
605    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
606      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
607      without requiring DO-IF statements
608    o pkg/thsice:
609      use continuous power-law function for partition of energy between lateral
610      melting/freezing and thinning/thickening ; old code using step function
611      still available with #undef THSICE_FRACEN_POWERLAW
612      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
613    o testreport: change AD testing : check against results/output_adm.txt
614      using same scripts as for forward test.
615    
616    checkpoint59g
617    o adjoint testing: in preparation for changing testreport:
618      - output format: cost and grad written on separated lines
619      - ad output results in directory "results" (instead of "results_ad")
620    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
621    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
622    o pkg/ecco: allow user defined cost function contributions
623    o testreport:
624      Allow to choose (per experiment) the list of tested output variables
625       and the main variable (used to issue a pass/FAIL ) ;
626      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
627      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
628      Also modify printing of summary:
629       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
630       b) echo the list of tested variables in the individual summary.txt of
631          each experiment.
632    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
633      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
634      (but still depend on the tile decompostion of the domain).
635    o pkg/seaice: change a discretization detail to make the B-grid code
636      "more symmetric". This change is likely to remove all "ridges/leads" that
637      where quasi-aligned with the grid in B-grid solutions. It may also be
638      the solution to the stress coupling issues with the B-grid.
639    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
640      remove .cvsignore from input dir. (since testreport no longer run here).
641    o pkg/thsice:
642     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
643     - fix reshaping of sea-ice just after advection:
644       melt all the ice only if ice-volume is too small.
645     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
646       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
647     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
648    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
649      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
650    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
651      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
652      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
653      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
654      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
655      -> update output.txt
656    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
657     this affects truncation error: -> update output.txt of exp:
658      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
659      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
660    
661    checkpoint59f
662    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
663    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
664      a bounded range (in forward mode)
665    o pkg/ecco, ctrl, autodiff and mom_common:
666     internal parameter controls, completements of implementations
667    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
668    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
669      (not seem any difference in testing results).
670    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
671       at face corners.
672    o pkg/generic_advdiff:
673     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
674      loop range indices for computing vertical advection tendency
675      and do the calculation in the interior only (no overlap) ;
676      for now, only implemented for SOM advection (to save CPU time).
677     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
678    o exch2 adjoint
679      First set of changes:
680      - add exch2 hand-written adjoint templates
681      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
682        This will require cleanup in pkg/autodiff/*.F
683        (changed routines currently kept separate in verif. code/)
684      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
685        that used to hide exch2 or cubed-sphere specific code
686        (commented via 'cph-exch2')
687    o pkg/seaice
688      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
689    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
690       output of global_ocean.cs32x15.thsice .
691    
692    checkpoint59e
693    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
694      for B-grid vector (not yet tested) and C-grid vector (<- only used
695      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
696    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
697      (#ifdef ALLOW_SALT_PLUME)
698    o gather_2d/scatter_2d: removed halo regions
699    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
700      scheme and the corresponding test case (under front_relax dir). For now,
701      only available with Skew-flux form and not yet tested in realistic set-up.
702      adjoint: store directives updated, but gradient checks deteriorated,
703      so maybe GM/Redi adjoint is now broken.
704    o seaice adjoint
705      * add AREA, HEFF, HSNOW as control variable
706        (should not change lab_sea results)
707      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
708    o pkg/seaice:
709      * added computation of saltFlux in seaice_growth;
710        For time being, sea ice salinity is assumed constant
711        contribution of snow flooding to freshening of sea ice is neglected.
712        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
713        defaults to 0.0 in order to maintain backward compatibility.
714        Typical values for SEAICE_salinity are 4 to 10 g/kg.
715      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
716      * added SEAICE_availHeatFrac, which specifies fraction of surface level
717        heat content used to melt or grow ice
718      * commented out cap of HICE: it helps keep ice thinner
719      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
720      * applied OBCS T/S mask to HEFFM sea ice mask
721    
722    checkpoint59d
723    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
724     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
725     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
726    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
727     and change default value of parameter "GM_Small_Number";
728     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
729       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
730       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
731    o pkg/ecco: cost function when applying pkg/smooth to controls
732    o pkg/ctrl: add forcingPrecond run time parameter
733    o pkg/seaice:
734     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
735     - fix bug in metric terms of u-equation in LSR solver (implicit part),
736       changes verification/lab_sea
737     - rearrange implicit part of u-equation in LSR solver to make it easier to
738       read, understand, and debug. This causes changes at the truncation level.
739     - fix (serious) bug in the boundary conditions (sign error in the implicit
740       part) of the LSR solver. Changes all LSR results.
741     - fixed problem with HSNOW initialization to avoid thick snow when AREA
742       is initilized with small values - does not change lab_sea results.
743     - added HsnowFile initialization capability
744    o pkg/smooth: addition to model/src and pkg/ctrl so allow
745     initialization of pkg/smooth and application to control vector
746    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
747    o dependencies: pkg/profiles requires pkg/cal
748    o pkg/profiles:
749     - added option ALLOW_PROFILES_GENERICGRID
750         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
751         that interpolation information (grid points and coefficients) is provided
752         within the netcdf input files.
753         -> sample matlab scripts can be found in MITgcm_contrib/gael
754         that allow you to prepare netcdf input files.
755     - also modified: cleaner include statements, cleaner error print statements,
756       cleaner stops when error, and more tests of the netcdf input files consistency.
757    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
758    o pkg/seaice:
759     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
760       requires a new routine: seaice_diagnostics_fill.F
761     - make sure that seaice does not move if not forced (pressure replacement
762       method, Hibler and Ip, 1995), changes results
763     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
764     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
765       It is turned off by default (=-1.), because it changes the results.
766     - make it possible to read AREA from a file, too.
767    
768    checkpoint59c
769    o add S/R and diagnostics for oceanic mixed-layer depth
770    o move GMRedi call after all vertical mixing schemes (including KPP)
771    o pkg/thsice:
772     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
773      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
774    o pkg/obcs:
775     - bug fix for balance code
776    o pkg/seaice:
777      - allow values of SEAICE_elasticParm > 1
778      - add new parameter SEAICE_evpTauRelax as an alternative
779        to SEAICE_elasticParm
780      - make lsr boundary conditions free slip (by default), changes result
781      - add code for no slip boundary conditions for lsr
782      - set minimum of zeta to zero (and not 4e8) (changes results)
783      - add a cap on AREA after advecting AREA if seaice_growth is not called
784    o change calculation of Visbeck K:
785      - no longer depend on tapering scheme; instead, compute slope (limited
786        by GM_maxSlope). this is equivalent to what was comuted before with
787        clipping or linear tappering.
788      - fix vertical averaging (wrong by 1/2 level)
789      - leave the old version (but will not be maintained) within
790        #ifdef OLD_VISBECK_CALC / #endif
791      - update output of exp. ideal_2D_oce
792    o change error catch in calc_r_star to improve vectorization
793    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
794      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
795    o adjoint:
796      Re-organized adjoint checkpointing according to Matt Mazloff
797      (but with modifs/completions/cleanups)
798      Storing is now bundled into large arrays to optimized I/O
799      (and second step in cleanup of the_main_loop)
800    
801    checkpoint59b
802    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
803      - export/import (between ocean & coupler) fields needed for ocean DIC.
804    o pkg/seaice:
805      - get rid of three more exchanges seaice_calc_viscosities (required
806        different loop boundaries in seaice_lsr and seaice_ocean_stress)
807      - bug fix in seaice_ocean_stress (update of lab_sea required)
808      - reduce loop boundaries to necessary minimum also in seaice_evp
809      - go back to the old way of computing deltaC/Z as the adjoint likes that
810        better
811    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
812      passive tracer to an Age Tracer) + update output.txt
813    o pkg/exf:
814      - implement A-grid / C-grid selection for wind-stress input files.
815      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
816      for now, in exf_bulk_largeyeager04.F only :
817      - change implementation for case where windspeed + 2. components wind-stress
818        are read-in. AND use rhoConstFresh to convert evap.
819    o pkg/seaice:
820      - use correct EXCH_UV for wind-forcing (on A-grid).
821      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
822        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
823    o pkg/exf:
824      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
825      EXF_INTERPOLATION:
826      - merge global_with_exf/code version of exf_interp_read.F
827        to the main code ;
828      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
829        reading the file ; Important: This options needs to be defined to recover
830        previous code.
831        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
832      - no longer loose real*8 precision along the way when using exf_iprec=64.
833    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
834      - change discretisation of evp-solver in order to avoid another exchange
835        (changes lab_sea) and clean up a little
836      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
837        help the adjoint (this also changes the results slightly)
838      - add a few "_d 0" where they had been missing in seaice_evp.F
839      - cleaning up: remove unused seaice_calc_rhs.F
840    o pkg/exf: some cleaning-up:
841      - change various "constants" into runtime parameters
842      - cleaned-up Large&Yeager04 routine which should eventually
843        replace exf_bulkformulae.F (changed names of S/R and CPP)
844        and merged various ALLOW_ATM_WIND options
845     only used with thsice pkg (in thsice_get_exf.F):
846      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
847        which are used when useStabilityFct_overIce=TRUE (= the default)
848      - change default values of ice & snow emissivity and scale downward LW
849        by ice & snow emissivity.
850    o pkg/thsice:
851     fix few little problems, in thsice_calc_thickn.F:
852      - growth vertically (and not laterally) if iceFrac == iceMaskMax
853      - melt only laterally if hIce < hThinIce (as the comments say)
854      and in thsice_extend.F:
855      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
856      - start to form ice as soon as the minimum ice-volume is reachable.
857     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
858      and cpl_aim+ocn
859    o pkg/kpp
860     - move computation of surface related input fields to KPP into a new
861       subroutine kpp_forcing_surf.F
862     - remove wrong (within bi,bj loops) EXCH calls.
863     - little cleaning (add argument myThid in last position, cvs header ...)
864     - for now, fix conservation problem by exchanging KPPviscAz (may not
865       be the best fix)
866    o pkg/seaice
867     - check for inconsistent evp parameter/cpp-flag combination
868     - remove leftover errIO flat for obsolete name list error handling
869    o OpenAD
870     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
871    
872    checkpoint59a
873    o pkg/seaice: some parameter clarifications and a little bit of clean up
874    o pkg/thsice: rename run-time parameters:
875       himin       -> hIceMin
876       himin0      -> hThinIce
877       hihig       -> hThickIce
878       i0          -> i0swFrac
879       transCoef   -> bMeltCoef
880       frac_energy -> fracMelting
881      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
882       with default values (for now) that do not change the results.
883      remove old version of thsice vars advection in pkg/seaice.
884    o in FFIELDS.h:
885      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
886      - make pLoad & sIceLoad always available (but still only used if
887         ATMOSPHERIC_LOADING is #define).
888    o pkg/kpp: replaced _KPP_RL with _RL
889    o bug fixes for vertical diffusivity computations when both KPP and
890        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
891        are no longer updating the vertical diffusivity array
892        (passed as argument) but are (re-) setting those arrays.
893    o pkg/seaice: fix bug in evp solver, while doing that
894      - change (improve?) discretization of stress computations for both
895        cgrid-lsr and evp solver
896      - add a new routine to compute strain rates
897      - the above changes lab_sea results
898      - add no slip conditions for evp solver (off by default), lsr-version
899        may follow
900      - fix exchange for shear at Z-points (does not change lab_sea)
901      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
902        (to force the user to pick a time step since there is not "safe" way
903        of choosing it)
904      - add principal stress diagnostics
905      - rearrange fields for evp a little to avoid having to call a: too many
906        exchanges and b: exchanges for stress trensor components which we do
907        not have.
908      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
909        of evp, complete rewrite for lsr case (latter is does not yet work
910        in all cases)
911    o pkg/kpp: add code to have mixing in shelf ice caverns
912      - add myThid to all kpp routines (long overdue)
913    
914    checkpoint59
915    o pkg/exf:
916      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
917        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
918      - move exf header files from lower_case.h to UPPER_CASE.h ;
919        add missing cvs Header & Name
920      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
921      - add namelist param. selectStressGridPosition, exf_monFreq
922      - retire many _CLIM routines, and remove data.exf_clim
923        + params moved to data.exf
924        + climsst, climsss now handled by exf_set_gen, i.e.
925          climss?period=0 refers to constant field,
926          climss?period=-12 to monthly forcing
927      - split up namelists in data.exf
928    o pkg/seaice:
929      - remove seaice_exch and seaice_exch_uv
930      - remove superfluous exchange of theta
931      - add myThid to seaice_budget_ocean/ice
932      - add new interface for atmospheric wind forcing (C-grid only)
933        + new routine
934        + two new field (taux, tauy for stress over ice)
935        + removed one global field (DAIRN) for C-grid case only
936    o pkg/thsise
937      - 2nd set of modifs for thsice adjoint in conjunction with exf
938    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
939    
940    checkpoint58y_post
941    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
942      vertical diffusivity, similar to that in MOM4; turned on using
943      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
944      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
945    o Added capability for 3D specification of background vertical diffusion
946      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
947      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
948      "data" file that contains the 3D vertical diffusivity coefficients.
949    o ice dynamics (pkg/seaice) with thsice thermodynamics:
950      - add code within pkg thsice to advect & diffuse sea-ice fields
951      similar to (and will replace) what has been added in  seaice_advdiff.F,
952      but: - conserving Mass, Heat & Salt.
953           - better when using non-linear advection scheme (not yet fully tested)
954           - can also be used in atmospheric set-up (for now, only the diffusion).
955    
956    checkpoint58x_post
957    o IO option for global-file compact format:
958      - add options when generating topology (utils/exch2/matlab-topology-generator)
959      - add I/O capability (pkg/mdsio).
960      - adapt utils/matlab/rdmds.m to read this format.
961      for now long-line format not yet supported by pkg/mdsio (& exch2).
962    o shelfice: add a few diagnostics
963    
964    checkpoint58w_post
965    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
966      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
967      (and replace horiVertRatio in NH code).
968      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
969                         and tutorial_plume_on_slope (sensitive to truncation)
970    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
971      directly to drive seaice model (C-grid only)
972    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
973     - reintroduce computation of wind from stress,
974     - compute tau (in exf_bulkformulae.F) from windstress averaged to
975       mass points to avoid tau = 0
976     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
977    o rdmnc.m: make it work with "global" files created with gluemnc
978    o rdmnc.m : some improvements in dealing with singleton dimension
979      (tested on all testreport mnc output files).
980    o genmake2: disable pkg/profiles if netcdf test fails.
981    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
982    o move call to cal_readparms up to make calendar parameters/variable available
983      to all packages
984    
985    checkpoint58v_post
986    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
987      useDynP_inEos_Zc tested.
988    o pkg/exf: changes to properly interpolate/mask/scale initial fields
989    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
990      and portions thereof.  See read_cs.txt for description and examples.
991    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
992      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
993      following the great-circle arc between those 2 points.
994    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
995      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
996    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
997     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
998     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
999     - still needs work (not working with some options ; efficiency to improve)
1000       and serious testing.
1001     - use this scheme for temperature & salinity in 2 advection test exp.:
1002       advect_xy & advect_xz, respectively.
1003    
1004    checkpoint58u_post
1005    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
1006    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
1007    o testreport: add option "-skipdir" to skip some test.
1008    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
1009      momentum calculation.
1010    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
1011    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
1012      remove checkpoint.F and the_correction_step.F (no longer used);
1013      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
1014    o add option (linFSConserveTr) to correct for tracer source/sink due to
1015      Linear Free surface
1016    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
1017    o pkg/thsice: fix reading mnc-pickups
1018    
1019    checkpoint58t_post
1020    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
1021    o pkg/mdsio:
1022     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
1023       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
1024       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
1025     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1026     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1027       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1028     - new S/R (to replace MDSWRITEMETA), which allows to write more
1029       informations (variable names, time ...) to meta files.
1030     - modify rdmds.m to give back the meta file content.
1031    o pkg/diagnostics: change vertical interpolation to be safer, and more
1032       flexible (define p-levels to interpolate to in data.diagnostics);
1033      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1034       diagnostic pointer.
1035    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1036    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1037    o fix multi-category seaice:
1038     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1039       SEAICE_MULTICATEGORY
1040     - fix short wave heat flux
1041    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1042       and allow to use EVP solver. Change forward lab_sea: test both EVP
1043       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1044    o Initial check-in of lab_sea adjoint
1045      (very similar to natl_box_adjoint/code_seaice)
1046      * used C-grid and EVP solver
1047      * used KPP, GM/Redi
1048      * uses inAdExact=.TRUE.
1049      * gradient checks fail for both ADM and TLM
1050        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1051        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1052        issue is related to forward mismatch between g77 an ifort
1053    o pkg/seaice: overhaul of thermodynamics
1054     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1055     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1056     - move a few global fields out of SEAICE.h into seaice_growth.F and
1057       make them 2D (FICE/QNETO/ ...)
1058     - remove FO (it is the same as QNETO)
1059     - introduce a few local fields to avoid modifying external fields such
1060       as atemp, etc.
1061    
1062    checkpoint58s_post
1063    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1064      changed exf_set_gen.F so that
1065        genperiod=0 means input file is one time-constant field and
1066        genperiod=-12 means input file contains 12 monthly means
1067    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1068      this affects truncation error ; generate new output file for exp. which
1069      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1070        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1071        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1072        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1073        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1074        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1075    o start implementation of deep-atmosphere and anelastic formulation
1076    o verification: remove 2nd copy of input files and use script "prepare_run"
1077      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1078    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1079    o profiles: fix for multithreaded case
1080    
1081    o diagnostics: rename few diags:
1082      s/'PRESSURE'/'RCENTER '/g
1083      s/'TICE    '/'oceFreez'/g
1084      s/'TAUX    '/'oceTAUX '/g
1085      s/'TAUY    '/'oceTAUY '/g
1086      s/'SWFLUX  '/'oceQsw  '/g
1087      s/DIFx/DFxE/g
1088      s/DIFy/DFyE/g
1089      and add few ocean-forcing diagnostics:
1090      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
1091    o modifications to pkg/seaice/growth.F and budget.F, which change results of
1092      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
1093      as actual snow thickness.  It now refers everywhere to effective snow
1094      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
1095    
1096    checkpoint58r_post
1097    o modifications to pkg/seaice/growth.F, which change results of
1098      lab_sea experiment: fixes pertain to melting snow over open water, to
1099      masking EVAP under sea ice, and to using the correct AREA variable for
1100      computations of EVAP, PRECIP, HSNOW, and GHEFF
1101    o add ability to read bathy, salt, and theta using MNC (off by def)
1102    o add flooding algorithm and advection of HSNOW for pkg/seaice;
1103      both are turned off by default and do no change any results
1104    o seaice advection with pkg/thsice: a step toward the use of non-linear
1105      advection scheme, but #ifdef or commented out for now (requires more EXCH).
1106    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
1107      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
1108      in natl_box (affects results @ truncation level: update output.txt)
1109    o multi-threading and IO:
1110      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
1111      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
1112        (needed to work with SingleCpuIO): tested in all verif. exp.
1113    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
1114      affects the results (but none of the verification test uses this scheme).
1115    o Adding some pkg/diagnostics capability to pkg/seaice
1116      (will certainly be subject to changes)
1117    o ctrl: adding new control variables:
1118      lwflux, lwdown, evap, snowprecip, apressure, runoff
1119    
1120    checkpoint58q_post
1121    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
1122      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
1123      high_res_cube configuration by 4% on Columbia.
1124    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
1125      add (in global_with_exf/code) a version of EXF_INTERP_READ without
1126      dynamical allocation (seems to work in multi-threaded).
1127    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
1128      single CPU io) so that TAF does not have to see EESUPPORT.h
1129    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
1130    
1131    checkpoint58p_post
1132    o obcs: stop if obcs is used with useCDscheme = .true.
1133    o shelfice:
1134     - fix a sign error so that no slip at shelfice interface works
1135     - remove stop for combination non-hydrostatic code and shelfice. That does
1136       not mean, that the results are correct, but at least they are numerically
1137       stable
1138    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
1139    o added adjoint exch routined for all exch*3d* routines
1140      and updated flow directives
1141    
1142    checkpoint58o_post
1143    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
1144      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
1145    o change controling S/R for writing pickup file (new S/R do_write_pickup)
1146      and clean-up reading/writing of pickup files.
1147    o fix local version of read/write pickup (NH part) in rotating_tank/code
1148    o simplify EXCH interface:
1149     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1150     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1151    o added the regrid package
1152    o shelfice:
1153     - add a simple boundary layer scheme to reduce noise
1154     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1155    
1156    checkpoint58n_post
1157    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1158       local variable (not in common block).
1159    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1160      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1161      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1162        to work with SingleCpuIO.
1163    o add "_d 0" to real constant of pkg/cfc subroutines ;
1164       update exp. cfc_exemple & tutorial_cfc_offline output files.
1165    o multi-threading and IO:
1166      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1167        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1168      - barrier before and after reading.
1169      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1170      - avoid using MDS_WRITELOCAL for LAND pkg output.
1171      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1172        common-block variables ; Allows multi-threading with master-thread IO.
1173    o change default MAX_NO_THREADS from 32 to 4 ;
1174      and stop cleanly when MAX_NO_THREADS is too small.
1175    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1176    
1177    checkpoint58m_post
1178    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1179       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1180    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1181       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1182       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1183    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1184        add MITgcm_tutorials (= code + all the tutorials)
1185    o ecco, option to compute cost for total ssh (mean+anom)
1186    o consistent with addition of ptracer and ssh in pkg/profiles
1187    o profiles: adding ptracer and ssh
1188    o testreport: change multi-test output-file name
1189      (from output.txt.{name} to output.{name}.txt)
1190    o profiles: now ok for mutli-tiles case
1191    o seaice: add 4 parameters for different advection schemes for area,
1192      (effective) seaice thickness, enthalphy, and snow height. Their default
1193      is the standard parameter SEAICEadvScheme
1194    o calc_gw:
1195     - add cosFacU in zonal viscous flux (harmonic.visc.).
1196     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1197       of tutorial_plume_on_slope.
1198    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1199    o calc_gw: true flux-form, account for horizontal grid spacing.
1200      update rotating_tank results, but not plume_on_slope (affected at
1201      truncation level, 11 digits).
1202    
1203    checkpoint58l_post
1204    o calc_gw:
1205     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1206     - remove side-drag for now (need to fix it); update plume_on_slope results.
1207     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
1208    o commit code to make SST/SSS weights spatially variable
1209      (based on either variable in-situ or variable initial T/S weights)
1210    o pkg/ecco:
1211      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
1212        now based on horizontally varying weights wthetaLev, wsaltLev
1213      * cost_averagesflags now returns year indices in addition to day, month
1214      * sflux balance is performed on annual basis
1215        (sflxumm, sfluxmm2, bal_sfluxmm)
1216      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
1217        including separate counting and multipliers
1218    o pkg/rbcs
1219      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
1220    
1221    checkpoint58k_post
1222    o testreport:
1223     - always build in dir. "build" (if not there, mkdir build instead of building
1224       & running in input)
1225     - run in dir run (if it exists), in build otherwise.
1226     - call prepare_run (if input/prepare_run exists)
1227     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1228    o pkg/exf modifications to interpolation and rotation routines for more
1229       reasonable treatment of North Pole singularity: for tracers North Pole
1230       value is set to northernmost zonal-mean value, for zonal velocity it is
1231       set to zero, and for meridional velocity it is set to northernmost value.
1232    o pkg/exf/exf_check_range.F
1233     - add tile index to diagnostics and move stop statement to the very
1234       end of the routine.
1235    o pkg/diagnostics: (diagnostics_main_init.F)
1236      define title of isomorphic variables according to the current config.
1237    o pkg/thsice with pkg/seaice dynamics:
1238    - fix domain of computation (interior only, required for exf) and do exchanges
1239    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1240    o towards a standard way of dealing with multi-threading in MONITOR
1241      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1242    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1243       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1244    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1245    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1246    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1247       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1248    o tracer advection:
1249     - clean-up and simplify calc_common_factors.F
1250     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1251       advection subroutine (but still not used within DST advection S/R)
1252    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1253    
1254    checkpoint58j_post
1255    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1256      from file (collects calls previously in FORWARD_STEP)
1257    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1258    o adjoint store dir. adjusted accordingly
1259    o genmake2
1260      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1261    
1262    checkpoint58i_post
1263    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1264      on wind stress (SEAICEstressFactor defaults to 1.)
1265    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1266      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1267    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1268      on CS-grid: no longer loosing mass.
1269    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1270    o pkg/ggl90: fix sloppy output and fix a bug
1271    o pkg/seaice: added SEAICEuseEVPpickup parameter
1272      - Set to false in order to start EVP solver with
1273        non-EVP pickup files when using SEAICEuseEVP
1274      - fix sign error in diffusion in seaice_calc_rhs
1275    
1276    checkpoint58h_post
1277    * Modifications for bottom topography control
1278      o replace hFacC by _hFacC at various places
1279      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1280      o add non-self-adjoint cg2d_nsa
1281      o update autodiff support routines
1282      o re-initialise hfac after ctrl_depth_ini
1283      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1284    * Adding verification for 5x5 box (4-layer) bottom topography control
1285    
1286    checkpoint58g_post
1287    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1288       used for mean seasonal cycle, mean diurnal cycle); add an example
1289       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1290    o pkg/ggl90:
1291      - add parameter (minimum surface kinetic energy)
1292      - fix bug (avoiding division by zero)
1293    o couple pkg/thsice to pkg/seaice:
1294      - modify advection in seaice to accomodate new scalar fields to be advected
1295      - only muliDimAdection scheme work with seaice/thsice
1296      - mapping of thsice-variables to seaice-variables, back and forth
1297      - does not break the verification experiments, but does not give the
1298        desired results either
1299    o pkg/seaice
1300      - make (default) second order advection a bit less confusing?
1301    
1302    checkpoint58f_post
1303    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1304      to pkg/seaice):
1305      - new routines thsice_map_exf and thsice_get_exf provide the interface
1306      - add an additional formal parameter to thsice_solve4temp
1307    o pkg/exf:
1308      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1309      - correct Stefan-Boltzmann constant
1310      - new parameter for longwave surface emittance
1311      - separate some stuff from exf_bulkformulae into new routines  
1312        exf_radiation, exf_wind
1313      - add new parameters and constants: longwave emissivity for ocean, ice
1314        and snow, evaporation parameters over ice
1315      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1316        either wind from stress or stress from wind
1317    o pkg/thSIce:
1318    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1319    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1320       and THSICE_CALC_THICKN
1321    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1322    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1323      to make debugging easier.
1324    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1325    o pkg/bulk_force:
1326      - clean-up comments and parameters ;
1327      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1328    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1329      generate new output for test-experiment: aim.5l_cs.thSI
1330    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1331      testreport accordingly
1332    
1333    checkpoint58e_post
1334    o SEAICE_CGRID adjoint done
1335    o R_STAR adjoint implemented.
1336      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1337      * need to sort out init. of h0facc, etc.
1338    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1339      to be able to use it in pure forward.
1340    
1341    checkpoint58d_post
1342    o upgrade simple test-experiment to tutorial example:
1343     step.1: duplicate the experiment and (step.2) will remove the old copy.
1344      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1345      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1346      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1347      tutorial_global_oce_biogeo    <- copy of dic_example
1348      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1349      tutorial_plume_on_slope       <- copy of plume_on_slope
1350      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1351      tutorial_global_oce_optim     <- empty for now (David ?)
1352      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1353     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1354    o correct a sign problem in cost_scat.F
1355    o obcs and ptracers: fix boundary conditions for advections schemes
1356      with larger stencil
1357    o thsice adjoint: start
1358    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1359      completeness
1360    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1361      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1362    o ptracers adjoint:
1363      * avoid extensive recomputatations
1364      * fix missing re-init. of gptr (missed by TAF)
1365    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
1366      me to turn off the excessive output to STDOUT that this package produces
1367    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1368      and add those terms in Vector-Invariant formulation.
1369    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1370      if the control period (xx_hfluxperiod etc) is 0
1371    o in profiles pkg, clean routines and fix details
1372    o in ecco pkg, reading ssh data:
1373      fix problem in case the model does not start at iter0=0
1374    o fix mnc-pickup/restart for ptracers
1375    o new package prifiles:
1376      code to compute profile-based cost by Gael Forget
1377      (modifs in ecco, ctrl, autodiff)
1378    o Benign bug fix in initialization (spotted by M. Mazloff) of
1379      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1380    
1381    checkpoint58c_post
1382    o adjoint: finish NLFS adjoint and provide reference output in
1383      verification/global_ocean.90x40x15/results_ad_nlfs
1384    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1385      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1386      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1387      with SEAICE_CGRID defined.
1388    o move calendarDumps from "data" to "data.cal" and clean-up the code
1389      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1390    o add useEXF & useCAL flags (for now, set in hard-coded way)
1391    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1392      (were missing in NH mode, and wrong in quasihydrostatic mode).
1393      waiting for Chris updated version of calc_gw to add those CALLs.
1394    o fix bug in quasihydrostatic S/R ;
1395      add a test for this option: global_ocean.90x40x15.qshyd
1396    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1397      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1398    o add on/off flag useOffLine for package OFFLINE
1399    o seaice:
1400      - modify advection so that it works also on the C-grid
1401      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1402        problem in multi-tile runs with C-grid
1403      - add flags for clipping ice velocities and/or masking solver forcing
1404      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1405        C-grid solver
1406      - added a few comments to seaice_diffusion.F
1407      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1408        are now exclusive)
1409      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1410        required re-ordering the code a little:
1411       + make DAIRN global variable (defined in SEAICE)
1412       + move computation of the viscosities eta and zeta into a new separate
1413         routine (because I need to recompute them in seaice_ocean_stress.F)
1414    
1415    checkpoint58b_post
1416    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1417      update output.txt of exp. aim.5l_cs.thSI
1418    o various mnc cleanups and improvements:
1419      + shrink lookup tables by factor of ~4
1420      + better error reporting when running out of lookup space
1421      + able to handle longer path/file names (up to 500 chars)
1422    o adjoint:
1423      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1424      - TBD: "hidden" mom_vecinv recomp. in dynamics
1425    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1426     (allow to differentiate between forcing components using new integer flags:
1427      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1428     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1429    o ecco
1430      - enable trend removal from SSH anomaly obs.
1431    o adjoint
1432      - a fix for PmEpR when #undef EXACT_CONSERV
1433      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1434      - try to fix "hidden" recomp. in forward_step for NLFS
1435        (NLFS seems broken sometimes after I checked it in)
1436    o seaice:
1437     - add c-grid version of the dynamic solver:
1438       + three new routines that are the c-grid substitute lsr, dynsolver
1439         and ostres
1440       + put a few fields that were local to dynsolver into global common
1441         blocks, so that I can move the computation of stresses etc into
1442         seaice_lsr (saves coding but may break the adjoint).
1443     - replace more hardwired parameters by runtime parameters
1444     - add ice masks that mask the rhs of the implicit solvers where there
1445       is no ice (commented out in seaice_dynsolver, because i am not sure
1446       if this works properly), eventually this should replace the clipping
1447       of ice velocities in seaice_dynsolver to +/-40cm/s.
1448    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1449      include it only where its needed
1450    o move balancing of fluxes before the call of external_forcing_surf
1451    o seaice:
1452      - correct units of turning angles (now they are really in degrees)
1453      - move computation of GWATX/Y out of main routine into dynsolver
1454      - initialize GWATX/Y in seaice_init
1455    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1456      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1457    o seaice: add runtime flags for turning angles (default to zero)
1458    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1459      and trend from exf forcing and ctrl control adjustments
1460    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1461      (since checkpoint57x_post)
1462    o change the default rotation period to 86164.s = the Earth rotation
1463    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1464      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1465    o seaice advection: add code for choosing between the default (2nd order
1466      central differences) and multiDim advection schemes provided by
1467      pkg/generic_advdiff
1468    o seaice:
1469      - removed all references to SEAICE_GRID.h fields from
1470        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1471        (cubed-sphere configuration will change a little)
1472      - grid computations in seaice_init are obsolete now.
1473      - cleaned up code a little so that is easier to read (hopefully).
1474      - added new (better?) discretizations of default advection and diffusion
1475        (turn on with SEAICEuseFluxForm)
1476      - replace 1 in 3d global fields by kSurface in growth.F
1477      
1478    checkpoint58a_post
1479    o seaice:
1480      - bug fix in advect.F
1481    o shelfice:
1482      - separate shelfice load anomaly from pload (breaks with time
1483        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1484        Its default is 0., but it may be computed more cleverly from (unknown)
1485        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1486        done offline. A good approximation of the pressure load anomaly is
1487        necessary to avoid large initial adjustment processes underneath
1488        deep-reaching shelfice.
1489      - small fix in ISOMIP shelfice_thermodynamics
1490      - add more sophisticated thermodynamics of Hellmer (1989), this is
1491        now the default
1492      - give a few constants more intuitive names
1493    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1494      if bulk formulae are used in long integration (especially EmPmR). Turn
1495      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1496      if balancePrintMean, the imbalance that is substracted is printed to
1497      STDOUT.
1498    o fix bug (typo) in obcs_apply_eta.F
1499    o add a new package shelfice which enables us to model the circulation
1500      underneath shelf-ice with draughts of hundreds of meters.
1501     - works
1502     - to do: + include improved thermodynamics
1503              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1504                instead of new field kTopC
1505              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1506                instead of new field R_shelfIce and new code in ini_depth.F
1507                and ini_mask_etc.F?
1508              + adjust vertical mixing schemes?
1509    o seaice pkg:
1510     - add a cpp-flag to include a simple formula for a salinity dependent
1511       freezing point of sea water at the surface
1512     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1513       meridional stresses are now different (and hopefully correct)
1514    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1515       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1516       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1517    o pkg/diagnostics: add options and parameters for regional-statistics
1518       diagnostics ; define regions by reading a region-mask from a file
1519       (might add other options later)
1520    o pkg/bulk_force:
1521     - add option and parameters to use AIM surface-flux formulae.
1522     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1523       others forcing fields (defined in PARM05, parameter file "data") are loaded
1524       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1525     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1526     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1527     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1528       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1529     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1530    
1531    checkpoint58
1532    o add "--embed-source" option to genmake2 which, when the supporting
1533      tools can be compiled (as determined by genmake2) will turn on the
1534      embed_files package which then embeds the entire MITgcm source code
1535      (*.[fFhc] + Makefile) used for the build within the executable
1536      - requested by CNH but off by default
1537      - adds a paltry <9MB to the mitgcmuv executable in most cases
1538      - only writes the output when useEMBEDSRC in eedata is true
1539    o clean up 3-dim. relaxation codes:
1540      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1541      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1542      * Thanks to Tom Haine for testing!
1543    
1544    checkpoint57z_post
1545    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1546      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1547    o fix the pickup behavior for obcs in combination with ptracers
1548    o fix a bug in ptracers_external_fields_load
1549    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1550      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1551    o transfered surface NH pressure to eta field (if exactConserv).
1552    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1553         and update lab_sea output.txt file.
1554    o completing 3-dim. relaxation code: additional term
1555         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1556      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1557      * At compile time, in "EXF_OPTIONS.h" set
1558          #define  ALLOW_CLIMTEMP_RELAXATION
1559          #define  ALLOW_CLIMSALT_RELAXATION
1560      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1561          tauThetaClimRelax3Dim = 15552000.0,
1562          tauSaltClimRelax3Dim  = 15552000.0,
1563      * 3 cases:
1564          1) Use a constant-in-time 3-dim. field
1565          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1566          3) Real-time relax. to time-evolving prescribed field
1567    o Adding Laplacian-type smoothness constraint on
1568      initial and boundary (forcing) controls (ic, bc)
1569      * enable at compile-time via
1570        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1571      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1572      * Absolute scale somewhat unclear so far
1573      * no area weighting was included since no other cost term does so far
1574    
1575    checkpoint57y_post
1576    First step for a NLFS adjoint
1577    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1578    o new init. routines for calc_r_star, calc_surf_dr
1579    o still need to deal with ini_masks_etc
1580    o testreport seemed happy
1581    checkpoint57y_pre
1582    
1583    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1584    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1585    o add new offset feature to offline pkg (plus minor cleanup)
1586    o cfc fixes for final year of integration
1587    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1588      be in GCHEM_OPTIONS).
1589    
1590    checkpoint57x_post
1591    o fix testreport Pb in multiple test experiment.
1592    o cleanup our namelist syntax in verification:
1593      - make it more F95 standards compliant (some work still needed)
1594      - allows the vast majority of our tests to work with gfortran
1595    o Non-Hydrostatic:
1596     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1597     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1598    o Allow to apply AB on T,S rather than on AB(gT,gS):
1599     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1600     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1601       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1602     - need a "clever" read_pickup to restart from the other AB formulation
1603    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1604    o remove some unused variables (reduces number of compiler warnings)
1605    o adjoint
1606      * Disable useVariableViscosity for adjoint for time being
1607        (there are a number of extensive recomputations)
1608      * Initialize certain variables needed for adjoint
1609    
1610    checkpoint57w_post
1611    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1612                 fix the singleCpuIO RS version of MDSWRITEFIELD
1613       and add a WARNING if using globalFiles=T with multi-processors.
1614    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1615      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1616    o tracer advection scheme:
1617      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1618       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1619       was not very convenient).
1620      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1621       (further tests needed for the implicit DST & Flux-Limiter schemes).
1622    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1623      and sRef for convenience, handy, when you want to initialize
1624      ptracers in a large domain with a constant non-zero value. Also,
1625      untangle ptracers_init.F a little.
1626    
1627    checkpoint57v_post
1628    o change dome exp. to use variable viscosity in side-drag terms.
1629    o remove all the files from the cfc_offline test since they are now
1630      incorporated into tutorial_cfc_offline which has been producing
1631      identical results for a few days of testing
1632    o add new parameter: sideDragFactor to enable half-slip-side BC
1633      and change side-drag S/R to use viscosity from mom_calc_visc
1634      (can switch back by setting sideDragFactor=0.); affects results at
1635      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1636       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1637    o vorticity & strain are now computed without masking, to account for
1638      no-slip-side BC in variable viscosity calculation ; mask is applied
1639      anyway later on, before computing advection/coriolis terms.
1640    o modify exp4 to test new obcs support for reading from external files
1641      and for passive tracers
1642    o fix behavior of ptracers_monitor when monitor output is written to a
1643      netcdf-file; still not independent of monitor.F (writes in the same
1644      file).
1645    o change default value of tRef (put a uniform, meaningful value for ocean
1646      & atmos) and initialize sRef (was missing, as Martin mentioned).
1647    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1648      to be proportional to enstrophy dissipation length.  Thus,
1649       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1650      This is now consistent with Smagorinsky and with the manual.
1651    
1652    checkpoint57u_post
1653    o OBCS and PTRACERS: add open boundary support for passive tracers
1654      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1655        OB-values from file; this is not different from the way theta and salinity
1656        are treated
1657      - however, Orlanski-radiation conditions are not supported, and the model
1658        will stop if you use pTracers and Orlanski at the same time.
1659      - beefed up the rountine obcs_external_fields_load: now only those open
1660        boundary values are overwritten with values from files for which there
1661        are really files, otherwise the OB-fields remain untouched. This makes
1662        it possible to use different OBs at different ends of the domain (as
1663        with EXF)
1664    o reduce number of exch calls in shap_filt (s2).
1665    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1666      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1667    
1668    checkpoint57t_post
1669    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1670    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1671      same truncation, independent of the face number: affects affects several
1672      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1673    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1674      note that biharmonic viscosity + no-slip was not tested in any experiment.
1675    o fix bug in non-linear free-surf side-drag ; generate new output for
1676      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1677    o make mnc honor the writeBinaryPrec flag for most kinds of output
1678    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1679    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1680      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1681    o add brackets in multi-terms sum to get same truncation, independent of
1682      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1683      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1684    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1685      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1686      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1687      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1688      Suggested values of viscosity parameters found in mom_calc_visc.
1689      Many new viscosity diagnostics available.
1690    
1691    checkpoint57s_post
1692    o Add clearing-house for viscosity calculations, mom_calc_visc and
1693      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1694      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1695      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1696      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1697      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1698      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1699      ViscAhStrain and viscAhTension are now retired.
1700    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1701    o In response to JMC's bug report, genmake2 now ignores any soft-links
1702      that it finds in the *current* directory when searching for files.
1703      Soft-links found in any other source directories will still work as
1704      they did before.
1705    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1706      a C routine to unlimit the stack size
1707    o mnc-ify pkg/aim snapshot vars
1708    o mnc-ify pkg/land as requested by Daniel
1709    o various changes to mnc including:
1710      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1711      - output can now be grouped so that all files within a group
1712          change the ITER portion of their names in lock-step together
1713      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1714          and works with both EXCH1 and EXCH2 (but needs more testing)
1715      - writing works for all verification test cases w/ g77 on Linux
1716    
1717    checkpoint57r_post
1718    o make MNC variable initialization happen earlier
1719    o add diagnostics for (almost) each term of the momentum Eq.
1720    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1721    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1722    o remove MINIMAL_TAVE_OUTPUT option ;
1723      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1724    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1725      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1726    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1727    o add time-dependent SST, SSS control
1728    o cost terms in ecco/ modularized (new cost_generic.F)
1729    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1730    o new infrastructure for seaice model vs. obs misfits in seaice/
1731      * driver from the_main_loop.F is seaice_cost_driver.F
1732      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1733      * gradient check in Exp. 6a of natl_box_adjoint/
1734    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1735      (see README file)
1736    
1737    checkpoint57q_post
1738    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1739    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1740      - bug was reported by Jean-Michel and Ian Fenty
1741    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1742      update exp. cpl_aim+ocn output.
1743    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1744      Needed for high-res. runs with large global files
1745      to be able to limit tapelev size
1746    o Changed some tests for adjoint:
1747      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1748      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1749      * global_ocean.90x40x15/ back to default 3-level checkpointing
1750    o Modifications to enable scripted COMMON to MODULE conversion
1751      * verification/OpenAD/code/ has necessary scripts and description;
1752      * converts, compiles and runs successfully;
1753    
1754    checkpoint57p_post
1755    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1756    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1757      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1758    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1759    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1760      (was already the case for dissipation with mom_vecinv,
1761       and also the case for grad.PhiHyd when staggered-timeStep)
1762      This will allow to put dissipation out-off the AB time-stepping.
1763     Unfortunately, affects truncation error. Update output of exp. that "fails"
1764      (cg2d matching number) and leave the others for later: front_relax(10),
1765      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1766      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1767    
1768    checkpoint57o_post
1769    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1770      (2) its ready to be documented during the 20050801 DocFest
1771    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1772      for ideal_2D_oce and lab_sea on linux_ia32_g77
1773    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1774      in global1x1_tot/code_seaice_adj to access indices 32, 33
1775      (worth another tag)
1776    
1777    checkpoint57n_post
1778    o adding precip control xx_precip 32
1779    o adding swflux control xx_swflux 33
1780    o Replacing 10 forcing penalty cost routines by 1 generic.
1781    o Implementing partitioning in time-mean and variable adjustment
1782      for atmos. state.
1783    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1784  o in natl_box_adjoint:  o in natl_box_adjoint:
1785    * updated: results_bulk/    * updated exp 1 to 10
1786    * not yet updated: results/, results_seaice/      (but does not have time-mean vs. variable split results yet)
1787    o updated global1x1/*_seaice_adj/
1788      to incorporate latest changes
1789    o enable useSingleCpuIO for mdsio vector routines
1790      (applies in particular to tapelev I/O)
1791    o removed inefficient K-loop in all active_file*control*.F
1792    
1793  checkpoint57m_post  checkpoint57m_post
1794  o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)  o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
