5      ==============================      ==============================
6    
7    o pkg/ctrl:
8      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
9    o non-hydrostatic (calc_gw.F):
10      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
11      update output of exp. global_ocean.cs32x15.viscA4
12    o remove backward compatibility for thetaMin,phiMin
13      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
14    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
15      interpolated wind field not only for curvilineargrid=.true., but also
16      for a rotated grid (rotateGrid=.true.)
17    o pkg/exf: add capability to bypass interpolation for runoff
18      by setting yet another CPP-flag
19    o eesupp/src, B-grid exchange:
20      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
21    o autodiff
22      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
23      allows to switch to single-prec common blocks;
24      corresponding switch occurs in tamc.h, integer isbyte
25      TAF store directivs "byte" and "kind" seem equivalent;
26      Most tamc.h have been updated correspondingly.
27    
28    checkpoint61i
29    o autodiff:
30      fix autodiff_sore/_restore indices for obcs
31      (spotted by I. Hoteit, M. Mazloff)
32    o pkg/autodiff, pkg/ctrl:
33      Add flag to reduce all tapelev I/O to single-prec.
34      In data.ctrl set
35        doSinglePrecTapelev = .TRUE.
36    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
37      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
38    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
39      real fresh water flux (not yet)
40    o pkg/mdsio & rw:
41     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
42     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
43    o pkg/flt:
44     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
45       init_fixed & ini_varia.
46     - clean-up & simplify linear interpolation S/R:
47       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
48     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
49     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
50     - add vert. coordinate & horiz. indices to output files.
51     - change vertical position in initial condition, from index to depth [m].
52     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
53       (easier to get to a curvilinear grid) ; delX,delY no longer used.
54    o pkg/ggl90: a few modifications:
55     - fix bottom boundary condition, and interpolation of KappaE
56       near top and bottom
57     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
58     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
59     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
60    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
61      (maintain temporary backward compatibility, until next checkpoint)
62    
63    checkpoint61h
64    o pkg/diagnostics with "periodic averaging diagnostics":
65      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
66    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
67    o pkg/obcs: fix loop ranges for balancing code
68    o pkg/flt:
69     - improve criteria for finding which tile owns a float.
70     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
71    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
72      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
73      with ocean biogeo)
74    o pkg/flt:
75     - do some cleaning and fix the restart ;
76     - add output.txt in flt_example/results to get this pkg tested.
77    o genmake2: add an EXTENDED_SRC option and flag.
78       for now, cannot be turned on on command line (only through genmake_local)
79    o pkg/mdsio: read/write vector:
80     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
81     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
82       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
83     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
84      (drop to 4 digits matching for grad). But this test does not look very
85      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
86    
87    checkpoint61g
88    o pkg/flt:
89      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
90       + make OPTIONS file more standard.
91      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
92      - fix _BYTESWAPIO CPP-Flag
93      - standard reading of file-parameter "data.flt"
94      - fix argument list of S/R FLT_RESTART
95      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
96    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
97    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
98      a still unfixed compiler/optimization bug
99    
100    checkpoint61f
101    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
102      update results of global_ocean.cs32x15.icedyn test.
103    o move getcon.F from model/src to pkg/fizhi.
104    o pkg/exf: add parameter for extrapolation of temp up to the surface
105       and option to prevent negative evap (in bulk_largeyeager04 only).
106    o Prather Advection scheme: fix tracer conservation for divergent flow
107      (e.g., when using NonLin Free-Surface).
108    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
109    o gmredi (Visbeck-variable-K):
110     - add more parameters to Visbeck-variable-K.
111     - use a 5 points average for dSigmaR in Visbeck-K calculation
112       (more "homogenous": same stencil and same weights as in dSigmaH)
113     - update output of ideal_2D_oce experiment.
114    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
115      (#undef REAL4_IS_SLOW)
116     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
117       coordinate variable
118     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
119       (surface forcing fields), removes some of the functionality
120     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
121     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
122       probably not all: copy _RS surface flux fields to RL field before
123       calling DIAGNOSTICS_FILL
124     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
125       real*4 (CALL EXCH_*_RS) versions.
126     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
127       (generate new output).
128    
129    checkpoint61e
130    o gmredi (Visbeck-variable-K):
131      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
132      - change computation of Visbeck-K where Slope > Smax :        
133        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
134        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
135    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
136      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
137    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
138    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
139      does not become too large (to avoid precision problems in implicit-diffusion
140      solver); update ideal_2D_oce output.
141    o pkg ggl90:
142      - in ggl90_cal.F: compute only one set of visc/diff, used to
143        step forward TKE/T/S/momentum
144      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
145        have Prandlt =1)
146    o gmredi (fm07):
147      - add lower limit on Transition layer thickness + lower limit on 1/lambda
148      - allow to set few more params from data.gmredi
149    o pkg ggl90:
150          - add missing sqrt(2) factor in computation of mixing length
151            scale in ggl90_calc.F
152            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
153    
154    checkpoint61d
155    o adjoint modifs
156      - adapt to new field rhoInSitu
157      - allow to revert from StoreDynVars2D, StoreDynVars3D
158        to individual fields
159        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
160    o store 3-D (in-situ) density in commom block (DYNVARS.h)
161     - save 1 rho computation.
162     - no longer modify T & S inland when using down_slope pkg.
163    o gad_som : allow to switch to SOM advection for T & S without corresponding
164      pickup files (using new S/R: MDS_CHECK4FILE).
165    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
166      (for useSingleCpuIO to work in multi-threaded)
167    o pkg/shelfice:
168     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
169       with SHELFICEtopoFile in data.shelfice
170     - move code for reading ice shelf topography and modifying hFacC into separate
171       subroutines of the shelfice package
172     - separate initialisation of "fixed" and "variable" variables
173     - kTopC is not (yet) replaced by kSurfC, although this is possible
174    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
175    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
176      and rename:
177      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
178      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
179    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
180    
181    checkpoint61c
182    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
183      to add mass source/sink of fluid in the interior (3-D generalisation
184      of oceanic real-fresh water flux).
185    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
186    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
187    o new pkg: down_slope
188      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
189      - presently, modify T & S inland (dwnslp_calc_rho.F).
190        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
191      - implementation for ocean in P-coords not tested.
192      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
193    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
194      (to facilitate conversion of oceanic pkg to p-coordinate).
195    o change FIND_RHO to FIND_RHO_2D :
196      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
197    o new pkg: cheapaml
198    
199    checkpoint61b
200    o exch2:
201      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
202      - no longer depend on the order sequence (N,S,E,W).
203      - 3rd exchange no longer needed (tested with 24 tiles).
204      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
205      - exch_UV_A-grid readily available (but not yet tested).
206      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
207      (both are no longer needed) in exch_uv: no effect in forward run; but
208       get truncation error differences with adjoint exch.
209    o exch2:
210     - change index-bounds storage (moved from target to local tile,
211       more intuitive this way) ; rename/remove some variables.
212     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
213    
214    checkpoint61a
215    o exch2/matlab-topology-generator:
216      fix bug in index bounds for N-S internal exchange (hard to tell if this
217      had any effect on the solution).
218    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
219      is exceeded
220    o testreport: modify syntax of awk, so that it works also with
221      awk, and not only with nawk and gawk
222    
223    checkpoint61
224    o autodiff
225      Change default for TAF usage by removing argument '-nonew_arg'
226      This changes TAF subroutine argument list (ordering of active var.)
227      Omission of this flag leads to incompatibility w.r.t. TAMC
228      To restore TAMC-compatibility, need following modifs:
229      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
230      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
231      Tested TAF version is 1.9.22
232      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
233    
234    checkpoint60
235    --->>> This is the last checkpoint for which generating the adjoint
236    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
237    --->>> by default.
238    --->>> Future checkpoints will ommit this flag by default.
239    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
240    o pkg/grdchk: Add gradient check to etan0 perturbations.
241    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
242    o pkg/autodiff: more flexibility in zeroadj.
243      model/src: modifying do_oceanic_phys.F accordingly.
244    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
245    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
246      special setup of gmredi for which the adjoint is stable
247      enough for parameter optimization.
248    o bridging the gap between eddy stress and GM.
249      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
250          along with a change in CPP option (now ALLOW_EDDYPSI).
251      -> when using GM w/ GM_AdvForm:
252          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
253          is applied either in the tracer Eq. or in momentum Eq.
254          depending on data.gmredi (intro. GM_InMomAsStress).
255      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
256      The key modifications are in model/src/taueddy_external_forcing.F
257      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
258    
259    checkpoint59r
260    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
261      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
262      fix option to read coriolis(@ cell-corner) from files with CS-grid.
263    o pkg/mnc: add some attributes to standard 1D-coordinate variables
264    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
265      mass points, when using mnc for output
266      - add runtime parameter (missing_value, missing_value_int) to override
267        default (which is the value of getcon('UNDEF'))
268    o pkg/mnc: prepare mnc for the actual use of missing values with the
269      diagnostics package: small fix in mnc_cw_readwrite.template and more
270      initialisation of never used fields
271      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
272      versions
273    o pkg/thsice/thsice_ini_vars.F added default initial values so that
274      thermodynamics sea ice solver does not blow up when some initial fields
275      are missing.
276    o move from external_forcing_surf.F to ini_forcing.F
277      the p-coord. hack consisting in using pLoad to set phi0surf ;
278      update output of tutorial_global_oce_in_p (affected @ truncation level).
279    o Freshen up a bit hs94.1x64x5, notably:
280      remove rotationPeriod and tRef=5*0. (adjoint only), and add
281      exactConserv=.TRUE.
282    o pkg/generic_advdiff:
283      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
284      applies to files where Temperature & Salinity 2nd Order moments are used.
285    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
286      this uses a dynamically allocated internal state data structure
287      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
288      and requires a fortran 90 compiler
289    
290    checkpoint59q
291    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
292       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
293    o Refresh tutorial_global_oce_biogeo, notably:
294      - change bathymetry (put back seamounts in ACC, use hFacs)
295      - change EOS (POLY3 --> JMD95Z)
296      - use Bryan-Lewis vertical diffusivity
297      - use multidimensional advection
298      - remove old virtual virtual in dic pkg, now done through ptracer pkg
299      - change a couple of parameters in dic pkg
300    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
301    o pkg/obcs: change default to OBCSfixTopo = .true.,
302      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
303      - replace "debugMode" with "debugLevel .GE. debLevB"
304    o implementation of TAF directives for gchem,cfc,dic
305    o remove "exp5" (replaced by tutorial_deep_convection).
306    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
307      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
308      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
309      --> changes results in exp4, seaice_obcs
310    o tutorial_deep_convection :
311      update the set-up and increase resolution and domain size ; start
312      from pseudo initial conditions = output at t=120mn in order to see
313      something happening when running testreport.
314    o pkg/seaice: add os7mp as an advection scheme
315                  add check for advection schemes
316                  add a flag for restoring T and S underneath sea ice
317    o pkg/my82: add netcdf-support and diagnostics
318    o thsice pkg:
319      - Now hsMax limits snow height by turning it into ice following
320        flooding scheme (and now conserving energy)
321      - Slight rewriting of the formula in thsice_calc_thick.F
322      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
323      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
324    
325    checkpoint59p
326    o gchem / dic / cfc :
327      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
328      - add new parameter files: "data.dic" & "data.cfc" ;
329      - various re-arrangement in initialisation & header file ;
330      - fix tutorial_global_oce_biogeo for multi-threaded test.
331    o pkg/dic: test for "pickup_dic" file when restarting ;
332      if no pickup-file, can restart with a re-initialised pH (same as it did
333      before) providing pickupStrictlyMatch is set to False.
334    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
335      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
336    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
337      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
338    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
339     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
340       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
341    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
342       scheme to use for vorticty-term ;
343     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
344       (with default selectVortScheme, return to original discretisation)
345     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
346    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
347    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
348      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
349      also fix diagnostics VISCAHW & VISCA4W.
350    
351    checkpoint59o
352    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
353    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
354      move a few statemens out the main loop into separate loops
355    o pkg/shelfice:
356      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
357        (kg/m^2/s), does not break tests, because in verification/isomip,
358        rhoConstFresh=rhoConst (by accident)
359      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
360      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
361        new file model/src/seawater.F, so that they are available for all pkgs.
362      - convert potential temperature into in-situ temperature. This changes the
363        isomip tests => update tests
364    o add a flag writePickupAtEnd (default=true) to be able to suppress
365      writing a pickup at the last timestep
366    o tools/mpack-1.6 :
367      - disable automake (not working) and autoconf (not needed).
368      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
369        also cleaner with much less compilation warnings.
370    o pkg/profiles:
371      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
372      (for "less than 32 characters name" compiler requirement)
373    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
374      conditions that have a different sampling frequency than S/T/U/V obcs
375    o pkg/diagnostics (stats-diags):
376      - fix global Min/Max in case 1 processor get only empty tiles
377    o genmake2: replace (4 times)
378         make genmake_tc_1.o >> genmake_warnings 2>&1
379      with
380         COMM="$CC $CFLAGS -c genmake_tc_1.c"
381         echo $COMM >> genmake_warnings
382         $COMM >> genmake_warnings 2>&1
383      to make genmake2 always see the value of CC as specified in the optfile.
384    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
385      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
386      - modify verification advect_cs test to test SOM-advection on CS-grid.
387    o pkg/ctrl:
388      - Rewrite of ctrl_map_ini_ecco.F,
389        introducing a generic routine (ctrl_map_ini_gen.F).
390      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
391    
392    checkpoint59n
393    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
394      number in dedicate array "hdiag":
395      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
396        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
397      - many small changes (integer format) for large number of diagnostics
398      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
399        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
400    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
401      usingSphericalGrid, this allows to define the rotated grid coordinates
402      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
403      geographical coordinates according to the inverse of the rotation defined
404      by the Euler angles, so that Coriolis parameter and online-interpolation by
405      exf works with the geographical coordinates on XC/YC/XG/YG.
406      Naturally, this feature does not work with all packages, so some
407      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
408      profiles), because there the coordinates are assumed to be regular
409      spherical grid coordinates.
410    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
411      - introduce isopycnal diffusion coefficient control.
412    o tools/adjoint_options:
413      - additional control vector components.
414    o pkg/mnc: have mnc create marginally meaning full coordinate variables
415      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
416    o pkg/mypackage:
417      - add example of read/write pickup for state-var ;
418      - add entry points to the main code for state-vars diags & write-pickup.
419    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
420      transitions for useExfYearlyFields
421      - add new subroutine that determines the file to read from for
422        use*YearlyFields = .TRUE. and .FALSE.
423      - add a verification experiment to global_with_exf that tests
424        useExfYearlyFields with USE_EXF_INTERPOLATION defined
425    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
426      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
427      subroutines (which could be generated from a template, because they are
428      almost identical), for now they are included in obcs_prescribe_read.F for
429      simplicity
430    o pkg/exf:
431      - add a little more diagnostic to exf_interp_read (in analogy to
432        mds_read_field, can be turned off with debugLevel < debugLevA=1)
433      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
434        ugly but fast by unrolling short inner loops, inserting a unroll=8
435        directive in routine lagran, and splitting a loop and making do while the
436        outermost loop (the latter requires the intoduction of index arrays)
437    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
438    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
439      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
440    o verification/seaice_obcs: updated for restart test and latest options
441    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
442      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
443      for now this is only available for the C-grid code and also within
444      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
445    
446    checkpoint59m
447    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
448      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
449    o gad_som : fix flux output (& diagnostics) to have same units as other  
450      advection scheme fluxes (was previously multiplied by deltaT).  
451    o added verification/seaice_obcs both to test seaice open boundaries
452      and to provide an example matlab scrpt for generating them
453    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
454    o pkg/salt_plume: clean up salt_plume_frac.F to
455      remove redundancy in PlumeMethod 1 and 4
456    o pkg/kpp: added saltplume diagnostics
457    o pkg/obcs and pkg/seaice:
458      - do not set uice and vice to zero when OB*icefile are unspecified
459      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
460      - moved seaice tracer obcs after call to seaice_growth
461    o pkg/salt_plume: added various options for salt plume depth
462      criterion and for vertical distribution of the salt
463    
464    checkpoint59l
465    o pkg/ptracers: new version of ptracers pickup:
466      read meta file and write only fields which are needed to restart.
467      ( same logic as main pickup file ; also using pickupStrictlyMatch )
468    o pkg/seaice:
469      - add timescale for melting due to warm mixed layer as a means of
470        setting SEAICE_availHeatFrac more conveniently
471      - add a CPP-flag/runtime parameter check for flooding algorithm
472      - reformulated availHeat in seaice_growth.F to be independent of AREA
473    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
474      unit changes
475    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
476    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
477      SX vector computer.
478    o pkg/seaice:
479      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
480        seaice forcing fields can now be read only through pkg/exf
481      - removed some unused halos
482    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
483    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
484      or U/VICE from U/VWIND before computing U/VSTRESS
485    
486    checkpoint59k
487    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
488      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
489    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
490      all experiments pass when compile with un-initialised var. checking option.
491    o added pkg/salt_plume
492    o script to test restart (for now, in MITgcm_contrib/jmc_script)
493    o pkg/seaice: new read/write pickup version.
494      read meta file and write only fields which are needed to restart.
495      ( same logic as main pickup file ; also using pickupStrictlyMatch )
496    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
497    o lab_sea.hb87: modify the domain & update output.hb87.txt :
498      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
499      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
500      process. Fixed here by closing the domain at the Northern boundary.
501    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
502    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
503      a set of consecutive levels in/from a 3-D array.
504    o pkg/ptracers:
505      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
506      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
507    
508    checkpoint59j
509    o in pkgs: dic, obcs, offline, rbcs:
510      standard way to compute coeff. for time interpolation between 2 time reccords
511      which retains full precision (& make results less dependent on compiler).
512      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
513    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
514      packages instead of reading ice cover and wind speed separately
515    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
516     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
517      to allow to compile customized code before the update)
518    o cleaning-up:
519      - fix CPP instruction syntax in pkg/obcs
520      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
521        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
522      - fix some threads issue in IO parts.
523    o pkg/dic:
524      - add tons of "_d 0" (--> much better testreports !)
525       and then update outputs of tutorial_global_oce_biogeo
526    o pkg/mom_fluxform:
527      add a special version of momentum advection intended to conserve momentum
528      next to a bathymetry step or a coastline edge. (default = off = #undef)
529    o new read/write pickup version:
530      - for now, only implemented for main (mdsio) pickup file.
531      - write out only what is needed to restart; merge pickup_nh , pickup_ph
532        and main pickup together.
533      - read meta file; read only what is needed to restart; stop if a field
534        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
535        if it make sense (even if the restart is not perfect).
536      - if no meta file, assume that pickup to read corresponds exactly to
537        a pickup that would currently be written.
538      - read pickup written in the old format (until checkpoint59i) if it
539        recognizes an old meta file (no field-list).
540      - add a meta file in exp. which starts from a pickup: 2 cases:
541        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
542         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
543        b) a meta file describing the content of the associated pickup file
544         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
545    o pkg/mdsio & pkg/rw:
546      - new routine to read a meta file ; new set of routine to read
547        Multiple-fields file (with meta file).
548    o added open boundary conditions capability for seaice
549        HSNOW, HSALT, UICE, and VICE
550    
551    checkpoint59i
552    o adjoint:
553      * fix multiDimAdvection adjoint
554        (partial recomputation problem by TAF for fVerT(:,:,kDown)
555        and comlev1 size definition (maxpass vs. max. number of tracers)
556      * verification/global_ocean.90x45x15 adjoint now tests
557        NLFS and multiDimAdvection using DST3 (=30)
558      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
559    o pkg/kpp: add "_d 0" to real constant (if missing);
560      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
561      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
562    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
563      for internal parameters related to restart process (formerly from PARAMS.h)
564      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
565    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
566      as argument. (only atm2d & obcs write_pickup have not yet been updated)
567    o pkg/monitor:
568      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
569      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
570      - account for deep Atmosphere factor and density factor (anelastic)
571    o added open boundary conditions capability for seaice HEFF and AREA
572    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
573      thermodynamics
574      - requires a little reorganization, which affects the testreport results
575        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
576        so that now the conservative form is tested
577      - add a few comments
578    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
579    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
580    o add new diagnostics to seaice: advective, diffusive fluxes (only for
581      multidim-advection, for scheme 2 they are not filled) and transports,
582      thermodynamic growth rates
583    o change units of EmPmR (inside the code, + within coupling interface)
584      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
585      Affects results @ truncation level (cg2d match) and update output of
586       experiments: lab_sea(6), global_ocean.90x40x15(10),
587      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
588      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
589      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
590      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
591    
592    checkpoint59h
593    o pkg/exf:
594      - improve vectorization by moving if-statement out of loops in
595        exf_mapfields, exf_radiation
596      - exf_bulkformulae.F: introduce 2D fields and vectorize code
597    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
598    o testreport:
599      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
600        monitor & update offline_exf_seaice exp. output.
601      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
602    o pkg/seaice:
603      - bug fix in the evp solver: boundary conditions were affected be
604        masking of zMax/zMin (changes results)
605      - minor bug fix in boundary conditions in seaice_calc_strainrates
606        (changes results for no_slip)
607      - seaice_lsr.F: make interpolation of eta dependent on boundaries
608      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
609      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
610        stress formulation and no-slip boundary conditions
611    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
612      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
613    o pkg/seaice: a first HSALT time stepping equation has been checked in
614    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
615      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
616      without requiring DO-IF statements
617    o pkg/thsice:
618      use continuous power-law function for partition of energy between lateral
619      melting/freezing and thinning/thickening ; old code using step function
620      still available with #undef THSICE_FRACEN_POWERLAW
621      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
622    o testreport: change AD testing : check against results/output_adm.txt
623      using same scripts as for forward test.
624    
625    checkpoint59g
626    o adjoint testing: in preparation for changing testreport:
627      - output format: cost and grad written on separated lines
628      - ad output results in directory "results" (instead of "results_ad")
629    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
630    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
631    o pkg/ecco: allow user defined cost function contributions
632    o testreport:
633      Allow to choose (per experiment) the list of tested output variables
634       and the main variable (used to issue a pass/FAIL ) ;
635      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
636      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
637      Also modify printing of summary:
638       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
639       b) echo the list of tested variables in the individual summary.txt of
640          each experiment.
641    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
642      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
643      (but still depend on the tile decompostion of the domain).
644    o pkg/seaice: change a discretization detail to make the B-grid code
645      "more symmetric". This change is likely to remove all "ridges/leads" that
646      where quasi-aligned with the grid in B-grid solutions. It may also be
647      the solution to the stress coupling issues with the B-grid.
648    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
649      remove .cvsignore from input dir. (since testreport no longer run here).
650    o pkg/thsice:
651     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
652     - fix reshaping of sea-ice just after advection:
653       melt all the ice only if ice-volume is too small.
654     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
655       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
656     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
657    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
658      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
659    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
660      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
661      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
662      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
663      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
664      -> update output.txt
665    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
666     this affects truncation error: -> update output.txt of exp:
667      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
668      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
669    
670    checkpoint59f
671    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
672    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
673      a bounded range (in forward mode)
674    o pkg/ecco, ctrl, autodiff and mom_common:
675     internal parameter controls, completements of implementations
676    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
677    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
678      (not seem any difference in testing results).
679    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
680       at face corners.
681    o pkg/generic_advdiff:
682     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
683      loop range indices for computing vertical advection tendency
684      and do the calculation in the interior only (no overlap) ;
685      for now, only implemented for SOM advection (to save CPU time).
686     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
687    o exch2 adjoint
688      First set of changes:
689      - add exch2 hand-written adjoint templates
690      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
691        This will require cleanup in pkg/autodiff/*.F
692        (changed routines currently kept separate in verif. code/)
693      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
694        that used to hide exch2 or cubed-sphere specific code
695        (commented via 'cph-exch2')
696    o pkg/seaice
697      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
698    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
699       output of global_ocean.cs32x15.thsice .
700    
701    checkpoint59e
702    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
703      for B-grid vector (not yet tested) and C-grid vector (<- only used
704      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
705    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
706      (#ifdef ALLOW_SALT_PLUME)
707    o gather_2d/scatter_2d: removed halo regions
708    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
709      scheme and the corresponding test case (under front_relax dir). For now,
710      only available with Skew-flux form and not yet tested in realistic set-up.
711      adjoint: store directives updated, but gradient checks deteriorated,
712      so maybe GM/Redi adjoint is now broken.
713    o seaice adjoint
714      * add AREA, HEFF, HSNOW as control variable
715        (should not change lab_sea results)
716      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
717    o pkg/seaice:
718      * added computation of saltFlux in seaice_growth;
719        For time being, sea ice salinity is assumed constant
720        contribution of snow flooding to freshening of sea ice is neglected.
721        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
722        defaults to 0.0 in order to maintain backward compatibility.
723        Typical values for SEAICE_salinity are 4 to 10 g/kg.
724      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
725      * added SEAICE_availHeatFrac, which specifies fraction of surface level
726        heat content used to melt or grow ice
727      * commented out cap of HICE: it helps keep ice thinner
728      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
729      * applied OBCS T/S mask to HEFFM sea ice mask
730    
731    checkpoint59d
732    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
733     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
734     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
735    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
736     and change default value of parameter "GM_Small_Number";
737     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
738       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
739       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
740    o pkg/ecco: cost function when applying pkg/smooth to controls
741    o pkg/ctrl: add forcingPrecond run time parameter
742    o pkg/seaice:
743     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
744     - fix bug in metric terms of u-equation in LSR solver (implicit part),
745       changes verification/lab_sea
746     - rearrange implicit part of u-equation in LSR solver to make it easier to
747       read, understand, and debug. This causes changes at the truncation level.
748     - fix (serious) bug in the boundary conditions (sign error in the implicit
749       part) of the LSR solver. Changes all LSR results.
750     - fixed problem with HSNOW initialization to avoid thick snow when AREA
751       is initilized with small values - does not change lab_sea results.
752     - added HsnowFile initialization capability
753    o pkg/smooth: addition to model/src and pkg/ctrl so allow
754     initialization of pkg/smooth and application to control vector
755    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
756    o dependencies: pkg/profiles requires pkg/cal
757    o pkg/profiles:
758     - added option ALLOW_PROFILES_GENERICGRID
759         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
760         that interpolation information (grid points and coefficients) is provided
761         within the netcdf input files.
762         -> sample matlab scripts can be found in MITgcm_contrib/gael
763         that allow you to prepare netcdf input files.
764     - also modified: cleaner include statements, cleaner error print statements,
765       cleaner stops when error, and more tests of the netcdf input files consistency.
766    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
767    o pkg/seaice:
768     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
769       requires a new routine: seaice_diagnostics_fill.F
770     - make sure that seaice does not move if not forced (pressure replacement
771       method, Hibler and Ip, 1995), changes results
772     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
773     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
774       It is turned off by default (=-1.), because it changes the results.
775     - make it possible to read AREA from a file, too.
776    
777    checkpoint59c
778    o add S/R and diagnostics for oceanic mixed-layer depth
779    o move GMRedi call after all vertical mixing schemes (including KPP)
780    o pkg/thsice:
781     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
782      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
783    o pkg/obcs:
784     - bug fix for balance code
785    o pkg/seaice:
786      - allow values of SEAICE_elasticParm > 1
787      - add new parameter SEAICE_evpTauRelax as an alternative
788        to SEAICE_elasticParm
789      - make lsr boundary conditions free slip (by default), changes result
790      - add code for no slip boundary conditions for lsr
791      - set minimum of zeta to zero (and not 4e8) (changes results)
792      - add a cap on AREA after advecting AREA if seaice_growth is not called
793    o change calculation of Visbeck K:
794      - no longer depend on tapering scheme; instead, compute slope (limited
795        by GM_maxSlope). this is equivalent to what was comuted before with
796        clipping or linear tappering.
797      - fix vertical averaging (wrong by 1/2 level)
798      - leave the old version (but will not be maintained) within
799        #ifdef OLD_VISBECK_CALC / #endif
800      - update output of exp. ideal_2D_oce
801    o change error catch in calc_r_star to improve vectorization
802    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
803      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
804    o adjoint:
805      Re-organized adjoint checkpointing according to Matt Mazloff
806      (but with modifs/completions/cleanups)
807      Storing is now bundled into large arrays to optimized I/O
808      (and second step in cleanup of the_main_loop)
809    
810    checkpoint59b
811    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
812      - export/import (between ocean & coupler) fields needed for ocean DIC.
813    o pkg/seaice:
814      - get rid of three more exchanges seaice_calc_viscosities (required
815        different loop boundaries in seaice_lsr and seaice_ocean_stress)
816      - bug fix in seaice_ocean_stress (update of lab_sea required)
817      - reduce loop boundaries to necessary minimum also in seaice_evp
818      - go back to the old way of computing deltaC/Z as the adjoint likes that
819        better
820    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
821      passive tracer to an Age Tracer) + update output.txt
822    o pkg/exf:
823      - implement A-grid / C-grid selection for wind-stress input files.
824      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
825      for now, in exf_bulk_largeyeager04.F only :
826      - change implementation for case where windspeed + 2. components wind-stress
827        are read-in. AND use rhoConstFresh to convert evap.
828    o pkg/seaice:
829      - use correct EXCH_UV for wind-forcing (on A-grid).
830      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
831        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
832    o pkg/exf:
833      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
834      EXF_INTERPOLATION:
835      - merge global_with_exf/code version of exf_interp_read.F
836        to the main code ;
837      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
838        reading the file ; Important: This options needs to be defined to recover
839        previous code.
840        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
841      - no longer loose real*8 precision along the way when using exf_iprec=64.
842    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
843      - change discretisation of evp-solver in order to avoid another exchange
844        (changes lab_sea) and clean up a little
845      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
846        help the adjoint (this also changes the results slightly)
847      - add a few "_d 0" where they had been missing in seaice_evp.F
848      - cleaning up: remove unused seaice_calc_rhs.F
849    o pkg/exf: some cleaning-up:
850      - change various "constants" into runtime parameters
851      - cleaned-up Large&Yeager04 routine which should eventually
852        replace exf_bulkformulae.F (changed names of S/R and CPP)
853        and merged various ALLOW_ATM_WIND options
854     only used with thsice pkg (in thsice_get_exf.F):
855      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
856        which are used when useStabilityFct_overIce=TRUE (= the default)
857      - change default values of ice & snow emissivity and scale downward LW
858        by ice & snow emissivity.
859    o pkg/thsice:
860     fix few little problems, in thsice_calc_thickn.F:
861      - growth vertically (and not laterally) if iceFrac == iceMaskMax
862      - melt only laterally if hIce < hThinIce (as the comments say)
863      and in thsice_extend.F:
864      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
865      - start to form ice as soon as the minimum ice-volume is reachable.
866     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
867      and cpl_aim+ocn
868    o pkg/kpp
869     - move computation of surface related input fields to KPP into a new
870       subroutine kpp_forcing_surf.F
871     - remove wrong (within bi,bj loops) EXCH calls.
872     - little cleaning (add argument myThid in last position, cvs header ...)
873     - for now, fix conservation problem by exchanging KPPviscAz (may not
874       be the best fix)
875    o pkg/seaice
876     - check for inconsistent evp parameter/cpp-flag combination
877     - remove leftover errIO flat for obsolete name list error handling
878    o OpenAD
879     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
880    
881    checkpoint59a
882    o pkg/seaice: some parameter clarifications and a little bit of clean up
883    o pkg/thsice: rename run-time parameters:
884       himin       -> hIceMin
885       himin0      -> hThinIce
886       hihig       -> hThickIce
887       i0          -> i0swFrac
888       transCoef   -> bMeltCoef
889       frac_energy -> fracMelting
890      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
891       with default values (for now) that do not change the results.
892      remove old version of thsice vars advection in pkg/seaice.
893    o in FFIELDS.h:
894      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
895      - make pLoad & sIceLoad always available (but still only used if
896         ATMOSPHERIC_LOADING is #define).
897    o pkg/kpp: replaced _KPP_RL with _RL
898    o bug fixes for vertical diffusivity computations when both KPP and
899        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
900        are no longer updating the vertical diffusivity array
901        (passed as argument) but are (re-) setting those arrays.
902    o pkg/seaice: fix bug in evp solver, while doing that
903      - change (improve?) discretization of stress computations for both
904        cgrid-lsr and evp solver
905      - add a new routine to compute strain rates
906      - the above changes lab_sea results
907      - add no slip conditions for evp solver (off by default), lsr-version
908        may follow
909      - fix exchange for shear at Z-points (does not change lab_sea)
910      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
911        (to force the user to pick a time step since there is not "safe" way
912        of choosing it)
913      - add principal stress diagnostics
914      - rearrange fields for evp a little to avoid having to call a: too many
915        exchanges and b: exchanges for stress trensor components which we do
916        not have.
917      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
918        of evp, complete rewrite for lsr case (latter is does not yet work
919        in all cases)
920    o pkg/kpp: add code to have mixing in shelf ice caverns
921      - add myThid to all kpp routines (long overdue)
922    
923    checkpoint59
924    o pkg/exf:
925      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
926        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
927      - move exf header files from lower_case.h to UPPER_CASE.h ;
928        add missing cvs Header & Name
929      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
930      - add namelist param. selectStressGridPosition, exf_monFreq
931      - retire many _CLIM routines, and remove data.exf_clim
932        + params moved to data.exf
933        + climsst, climsss now handled by exf_set_gen, i.e.
934          climss?period=0 refers to constant field,
935          climss?period=-12 to monthly forcing
936      - split up namelists in data.exf
937    o pkg/seaice:
938      - remove seaice_exch and seaice_exch_uv
939      - remove superfluous exchange of theta
940      - add myThid to seaice_budget_ocean/ice
941      - add new interface for atmospheric wind forcing (C-grid only)
942        + new routine
943        + two new field (taux, tauy for stress over ice)
944        + removed one global field (DAIRN) for C-grid case only
945    o pkg/thsise
946      - 2nd set of modifs for thsice adjoint in conjunction with exf
947    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
948    
949    checkpoint58y_post
950    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
951      vertical diffusivity, similar to that in MOM4; turned on using
952      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
953      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
954    o Added capability for 3D specification of background vertical diffusion
955      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
956      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
957      "data" file that contains the 3D vertical diffusivity coefficients.
958    o ice dynamics (pkg/seaice) with thsice thermodynamics:
959      - add code within pkg thsice to advect & diffuse sea-ice fields
960      similar to (and will replace) what has been added in  seaice_advdiff.F,
961      but: - conserving Mass, Heat & Salt.
962           - better when using non-linear advection scheme (not yet fully tested)
963           - can also be used in atmospheric set-up (for now, only the diffusion).
964    
965    checkpoint58x_post
966    o IO option for global-file compact format:
967      - add options when generating topology (utils/exch2/matlab-topology-generator)
968      - add I/O capability (pkg/mdsio).
969      - adapt utils/matlab/rdmds.m to read this format.
970      for now long-line format not yet supported by pkg/mdsio (& exch2).
971    o shelfice: add a few diagnostics
972    
973    checkpoint58w_post
974    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
975      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
976      (and replace horiVertRatio in NH code).
977      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
978                         and tutorial_plume_on_slope (sensitive to truncation)
979    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
980      directly to drive seaice model (C-grid only)
981    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
982     - reintroduce computation of wind from stress,
983     - compute tau (in exf_bulkformulae.F) from windstress averaged to
984       mass points to avoid tau = 0
985     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
986    o rdmnc.m: make it work with "global" files created with gluemnc
987    o rdmnc.m : some improvements in dealing with singleton dimension
988      (tested on all testreport mnc output files).
989    o genmake2: disable pkg/profiles if netcdf test fails.
990    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
991    o move call to cal_readparms up to make calendar parameters/variable available
992      to all packages
993    
994    checkpoint58v_post
995    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
996      useDynP_inEos_Zc tested.
997    o pkg/exf: changes to properly interpolate/mask/scale initial fields
998    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
999      and portions thereof.  See read_cs.txt for description and examples.
1000    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
1001      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
1002      following the great-circle arc between those 2 points.
1003    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
1004      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
1005    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
1006     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
1007     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
1008     - still needs work (not working with some options ; efficiency to improve)
1009       and serious testing.
1010     - use this scheme for temperature & salinity in 2 advection test exp.:
1011       advect_xy & advect_xz, respectively.
1012    
1013    checkpoint58u_post
1014    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
1015    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
1016    o testreport: add option "-skipdir" to skip some test.
1017    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
1018      momentum calculation.
1019    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
1020    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
1021      remove checkpoint.F and the_correction_step.F (no longer used);
1022      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
1023    o add option (linFSConserveTr) to correct for tracer source/sink due to
1024      Linear Free surface
1025    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
1026    o pkg/thsice: fix reading mnc-pickups
1027    
1028    checkpoint58t_post
1029    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
1030    o pkg/mdsio:
1031     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
1032       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
1033       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
1034     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1035     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1036       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1037     - new S/R (to replace MDSWRITEMETA), which allows to write more
1038       informations (variable names, time ...) to meta files.
1039     - modify rdmds.m to give back the meta file content.
1040    o pkg/diagnostics: change vertical interpolation to be safer, and more
1041       flexible (define p-levels to interpolate to in data.diagnostics);
1042      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1043       diagnostic pointer.
1044    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1045    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1046    o fix multi-category seaice:
1047     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1048       SEAICE_MULTICATEGORY
1049     - fix short wave heat flux
1050    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1051       and allow to use EVP solver. Change forward lab_sea: test both EVP
1052       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1053    o Initial check-in of lab_sea adjoint
1054      (very similar to natl_box_adjoint/code_seaice)
1055      * used C-grid and EVP solver
1056      * used KPP, GM/Redi
1057      * uses inAdExact=.TRUE.
1058      * gradient checks fail for both ADM and TLM
1059        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1060        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1061        issue is related to forward mismatch between g77 an ifort
1062    o pkg/seaice: overhaul of thermodynamics
1063     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1064     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1065     - move a few global fields out of SEAICE.h into seaice_growth.F and
1066       make them 2D (FICE/QNETO/ ...)
1067     - remove FO (it is the same as QNETO)
1068     - introduce a few local fields to avoid modifying external fields such
1069       as atemp, etc.
1070    
1071    checkpoint58s_post
1072    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1073      changed exf_set_gen.F so that
1074        genperiod=0 means input file is one time-constant field and
1075        genperiod=-12 means input file contains 12 monthly means
1076    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1077      this affects truncation error ; generate new output file for exp. which
1078      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1079        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1080        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1081        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1082        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1083        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1084    o start implementation of deep-atmosphere and anelastic formulation
1085    o verification: remove 2nd copy of input files and use script "prepare_run"
1086      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1087    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1088    o profiles: fix for multithreaded case
1089    
1090    o diagnostics: rename few diags:
1091      s/'PRESSURE'/'RCENTER '/g
1092      s/'TICE    '/'oceFreez'/g
1093      s/'TAUX    '/'oceTAUX '/g
1094      s/'TAUY    '/'oceTAUY '/g
1095      s/'SWFLUX  '/'oceQsw  '/g
1096      s/DIFx/DFxE/g
1097      s/DIFy/DFyE/g
1098      and add few ocean-forcing diagnostics:
1099      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
1100    o modifications to pkg/seaice/growth.F and budget.F, which change results of
1101      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
1102      as actual snow thickness.  It now refers everywhere to effective snow
1103      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
1104    
1105    checkpoint58r_post
1106    o modifications to pkg/seaice/growth.F, which change results of
1107      lab_sea experiment: fixes pertain to melting snow over open water, to
1108      masking EVAP under sea ice, and to using the correct AREA variable for
1109      computations of EVAP, PRECIP, HSNOW, and GHEFF
1110    o add ability to read bathy, salt, and theta using MNC (off by def)
1111    o add flooding algorithm and advection of HSNOW for pkg/seaice;
1112      both are turned off by default and do no change any results
1113    o seaice advection with pkg/thsice: a step toward the use of non-linear
1114      advection scheme, but #ifdef or commented out for now (requires more EXCH).
1115    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
1116      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
1117      in natl_box (affects results @ truncation level: update output.txt)
1118    o multi-threading and IO:
1119      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
1120      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
1121        (needed to work with SingleCpuIO): tested in all verif. exp.
1122    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
1123      affects the results (but none of the verification test uses this scheme).
1124    o Adding some pkg/diagnostics capability to pkg/seaice
1125      (will certainly be subject to changes)
1126    o ctrl: adding new control variables:
1127      lwflux, lwdown, evap, snowprecip, apressure, runoff
1128    
1129    checkpoint58q_post
1130    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
1131      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
1132      high_res_cube configuration by 4% on Columbia.
1133    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
1134      add (in global_with_exf/code) a version of EXF_INTERP_READ without
1135      dynamical allocation (seems to work in multi-threaded).
1136    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
1137      single CPU io) so that TAF does not have to see EESUPPORT.h
1138    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
1139    
1140    checkpoint58p_post
1141    o obcs: stop if obcs is used with useCDscheme = .true.
1142    o shelfice:
1143     - fix a sign error so that no slip at shelfice interface works
1144     - remove stop for combination non-hydrostatic code and shelfice. That does
1145       not mean, that the results are correct, but at least they are numerically
1146       stable
1147    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
1148    o added adjoint exch routined for all exch*3d* routines
1149      and updated flow directives
1150    
1151    checkpoint58o_post
1152    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
1153      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
1154    o change controling S/R for writing pickup file (new S/R do_write_pickup)
1155      and clean-up reading/writing of pickup files.
1156    o fix local version of read/write pickup (NH part) in rotating_tank/code
1157    o simplify EXCH interface:
1158     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1159     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1160    o added the regrid package
1161    o shelfice:
1162     - add a simple boundary layer scheme to reduce noise
1163     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1164    
1165    checkpoint58n_post
1166    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1167       local variable (not in common block).
1168    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1169      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1170      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1171        to work with SingleCpuIO.
1172    o add "_d 0" to real constant of pkg/cfc subroutines ;
1173       update exp. cfc_exemple & tutorial_cfc_offline output files.
1174    o multi-threading and IO:
1175      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1176        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1177      - barrier before and after reading.
1178      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1179      - avoid using MDS_WRITELOCAL for LAND pkg output.
1180      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1181        common-block variables ; Allows multi-threading with master-thread IO.
1182    o change default MAX_NO_THREADS from 32 to 4 ;
1183      and stop cleanly when MAX_NO_THREADS is too small.
1184    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1185    
1186    checkpoint58m_post
1187    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1188       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1189    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1190       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1191       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1192    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1193        add MITgcm_tutorials (= code + all the tutorials)
1194    o ecco, option to compute cost for total ssh (mean+anom)
1195    o consistent with addition of ptracer and ssh in pkg/profiles
1196    o profiles: adding ptracer and ssh
1197    o testreport: change multi-test output-file name
1198      (from output.txt.{name} to output.{name}.txt)
1199    o profiles: now ok for mutli-tiles case
1200    o seaice: add 4 parameters for different advection schemes for area,
1201      (effective) seaice thickness, enthalphy, and snow height. Their default
1202      is the standard parameter SEAICEadvScheme
1203    o calc_gw:
1204     - add cosFacU in zonal viscous flux (harmonic.visc.).
1205     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1206       of tutorial_plume_on_slope.
1207    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1208    o calc_gw: true flux-form, account for horizontal grid spacing.
1209      update rotating_tank results, but not plume_on_slope (affected at
1210      truncation level, 11 digits).
1211    
1212    checkpoint58l_post
1213    o calc_gw:
1214     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1215     - remove side-drag for now (need to fix it); update plume_on_slope results.
1216     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
1217    o commit code to make SST/SSS weights spatially variable
1218      (based on either variable in-situ or variable initial T/S weights)
1219    o pkg/ecco:
1220      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
1221        now based on horizontally varying weights wthetaLev, wsaltLev
1222      * cost_averagesflags now returns year indices in addition to day, month
1223      * sflux balance is performed on annual basis
1224        (sflxumm, sfluxmm2, bal_sfluxmm)
1225      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
1226        including separate counting and multipliers
1227    o pkg/rbcs
1228      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
1229    
1230    checkpoint58k_post
1231    o testreport:
1232     - always build in dir. "build" (if not there, mkdir build instead of building
1233       & running in input)
1234     - run in dir run (if it exists), in build otherwise.
1235     - call prepare_run (if input/prepare_run exists)
1236     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1237    o pkg/exf modifications to interpolation and rotation routines for more
1238       reasonable treatment of North Pole singularity: for tracers North Pole
1239       value is set to northernmost zonal-mean value, for zonal velocity it is
1240       set to zero, and for meridional velocity it is set to northernmost value.
1241    o pkg/exf/exf_check_range.F
1242     - add tile index to diagnostics and move stop statement to the very
1243       end of the routine.
1244    o pkg/diagnostics: (diagnostics_main_init.F)
1245      define title of isomorphic variables according to the current config.
1246    o pkg/thsice with pkg/seaice dynamics:
1247    - fix domain of computation (interior only, required for exf) and do exchanges
1248    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1249    o towards a standard way of dealing with multi-threading in MONITOR
1250      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1251    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1252       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1253    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1254    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1255    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1256       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1257    o tracer advection:
1258     - clean-up and simplify calc_common_factors.F
1259     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1260       advection subroutine (but still not used within DST advection S/R)
1261    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1262    
1263    checkpoint58j_post
1264    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1265      from file (collects calls previously in FORWARD_STEP)
1266    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1267    o adjoint store dir. adjusted accordingly
1268    o genmake2
1269      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1270    
1271    checkpoint58i_post
1272    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1273      on wind stress (SEAICEstressFactor defaults to 1.)
1274    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1275      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1276    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1277      on CS-grid: no longer loosing mass.
1278    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1279    o pkg/ggl90: fix sloppy output and fix a bug
1280    o pkg/seaice: added SEAICEuseEVPpickup parameter
1281      - Set to false in order to start EVP solver with
1282        non-EVP pickup files when using SEAICEuseEVP
1283      - fix sign error in diffusion in seaice_calc_rhs
1284    
1285    checkpoint58h_post
1286    * Modifications for bottom topography control
1287      o replace hFacC by _hFacC at various places
1288      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1289      o add non-self-adjoint cg2d_nsa
1290      o update autodiff support routines
1291      o re-initialise hfac after ctrl_depth_ini
1292      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1293    * Adding verification for 5x5 box (4-layer) bottom topography control
1294    
1295    checkpoint58g_post
1296    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1297       used for mean seasonal cycle, mean diurnal cycle); add an example
1298       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1299    o pkg/ggl90:
1300      - add parameter (minimum surface kinetic energy)
1301      - fix bug (avoiding division by zero)
1302    o couple pkg/thsice to pkg/seaice:
1303      - modify advection in seaice to accomodate new scalar fields to be advected
1304      - only muliDimAdection scheme work with seaice/thsice
1305      - mapping of thsice-variables to seaice-variables, back and forth
1306      - does not break the verification experiments, but does not give the
1307        desired results either
1308    o pkg/seaice
1309      - make (default) second order advection a bit less confusing?
1310    
1311    checkpoint58f_post
1312    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1313      to pkg/seaice):
1314      - new routines thsice_map_exf and thsice_get_exf provide the interface
1315      - add an additional formal parameter to thsice_solve4temp
1316    o pkg/exf:
1317      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1318      - correct Stefan-Boltzmann constant
1319      - new parameter for longwave surface emittance
1320      - separate some stuff from exf_bulkformulae into new routines  
1321        exf_radiation, exf_wind
1322      - add new parameters and constants: longwave emissivity for ocean, ice
1323        and snow, evaporation parameters over ice
1324      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1325        either wind from stress or stress from wind
1326    o pkg/thSIce:
1327    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1328    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1329       and THSICE_CALC_THICKN
1330    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1331    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1332      to make debugging easier.
1333    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1334    o pkg/bulk_force:
1335      - clean-up comments and parameters ;
1336      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1337    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1338      generate new output for test-experiment: aim.5l_cs.thSI
1339    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1340      testreport accordingly
1341    
1342    checkpoint58e_post
1343    o SEAICE_CGRID adjoint done
1344    o R_STAR adjoint implemented.
1345      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1346      * need to sort out init. of h0facc, etc.
1347    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1348      to be able to use it in pure forward.
1349    
1350    checkpoint58d_post
1351    o upgrade simple test-experiment to tutorial example:
1352     step.1: duplicate the experiment and (step.2) will remove the old copy.
1353      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1354      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1355      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1356      tutorial_global_oce_biogeo    <- copy of dic_example
1357      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1358      tutorial_plume_on_slope       <- copy of plume_on_slope
1359      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1360      tutorial_global_oce_optim     <- empty for now (David ?)
1361      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1362     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1363    o correct a sign problem in cost_scat.F
1364    o obcs and ptracers: fix boundary conditions for advections schemes
1365      with larger stencil
1366    o thsice adjoint: start
1367    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1368      completeness
1369    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1370      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1371    o ptracers adjoint:
1372      * avoid extensive recomputatations
1373      * fix missing re-init. of gptr (missed by TAF)
1374    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
1375      me to turn off the excessive output to STDOUT that this package produces
1376    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1377      and add those terms in Vector-Invariant formulation.
1378    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1379      if the control period (xx_hfluxperiod etc) is 0
1380    o in profiles pkg, clean routines and fix details
1381    o in ecco pkg, reading ssh data:
1382      fix problem in case the model does not start at iter0=0
1383    o fix mnc-pickup/restart for ptracers
1384    o new package prifiles:
1385      code to compute profile-based cost by Gael Forget
1386      (modifs in ecco, ctrl, autodiff)
1387    o Benign bug fix in initialization (spotted by M. Mazloff) of
1388      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1389    
1390    checkpoint58c_post
1391    o adjoint: finish NLFS adjoint and provide reference output in
1392      verification/global_ocean.90x40x15/results_ad_nlfs
1393    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1394      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1395      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1396      with SEAICE_CGRID defined.
1397    o move calendarDumps from "data" to "data.cal" and clean-up the code
1398      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1399    o add useEXF & useCAL flags (for now, set in hard-coded way)
1400    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1401      (were missing in NH mode, and wrong in quasihydrostatic mode).
1402      waiting for Chris updated version of calc_gw to add those CALLs.
1403    o fix bug in quasihydrostatic S/R ;
1404      add a test for this option: global_ocean.90x40x15.qshyd
1405    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1406      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1407    o add on/off flag useOffLine for package OFFLINE
1408    o seaice:
1409      - modify advection so that it works also on the C-grid
1410      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1411        problem in multi-tile runs with C-grid
1412      - add flags for clipping ice velocities and/or masking solver forcing
1413      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1414        C-grid solver
1415      - added a few comments to seaice_diffusion.F
1416      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1417        are now exclusive)
1418      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1419        required re-ordering the code a little:
1420       + make DAIRN global variable (defined in SEAICE)
1421       + move computation of the viscosities eta and zeta into a new separate
1422         routine (because I need to recompute them in seaice_ocean_stress.F)
1423    
1424    checkpoint58b_post
1425    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1426      update output.txt of exp. aim.5l_cs.thSI
1427    o various mnc cleanups and improvements:
1428      + shrink lookup tables by factor of ~4
1429      + better error reporting when running out of lookup space
1430      + able to handle longer path/file names (up to 500 chars)
1431    o adjoint:
1432      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1433      - TBD: "hidden" mom_vecinv recomp. in dynamics
1434    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1435     (allow to differentiate between forcing components using new integer flags:
1436      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1437     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1438    o ecco
1439      - enable trend removal from SSH anomaly obs.
1440    o adjoint
1441      - a fix for PmEpR when #undef EXACT_CONSERV
1442      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1443      - try to fix "hidden" recomp. in forward_step for NLFS
1444        (NLFS seems broken sometimes after I checked it in)
1445    o seaice:
1446     - add c-grid version of the dynamic solver:
1447       + three new routines that are the c-grid substitute lsr, dynsolver
1448         and ostres
1449       + put a few fields that were local to dynsolver into global common
1450         blocks, so that I can move the computation of stresses etc into
1451         seaice_lsr (saves coding but may break the adjoint).
1452     - replace more hardwired parameters by runtime parameters
1453     - add ice masks that mask the rhs of the implicit solvers where there
1454       is no ice (commented out in seaice_dynsolver, because i am not sure
1455       if this works properly), eventually this should replace the clipping
1456       of ice velocities in seaice_dynsolver to +/-40cm/s.
1457    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1458      include it only where its needed
1459    o move balancing of fluxes before the call of external_forcing_surf
1460    o seaice:
1461      - correct units of turning angles (now they are really in degrees)
1462      - move computation of GWATX/Y out of main routine into dynsolver
1463      - initialize GWATX/Y in seaice_init
1464    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1465      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1466    o seaice: add runtime flags for turning angles (default to zero)
1467    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1468      and trend from exf forcing and ctrl control adjustments
1469    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1470      (since checkpoint57x_post)
1471    o change the default rotation period to 86164.s = the Earth rotation
1472    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1473      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1474    o seaice advection: add code for choosing between the default (2nd order
1475      central differences) and multiDim advection schemes provided by
1476      pkg/generic_advdiff
1477    o seaice:
1478      - removed all references to SEAICE_GRID.h fields from
1479        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1480        (cubed-sphere configuration will change a little)
1481      - grid computations in seaice_init are obsolete now.
1482      - cleaned up code a little so that is easier to read (hopefully).
1483      - added new (better?) discretizations of default advection and diffusion
1484        (turn on with SEAICEuseFluxForm)
1485      - replace 1 in 3d global fields by kSurface in growth.F
1486      
1487    checkpoint58a_post
1488    o seaice:
1489      - bug fix in advect.F
1490    o shelfice:
1491      - separate shelfice load anomaly from pload (breaks with time
1492        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1493        Its default is 0., but it may be computed more cleverly from (unknown)
1494        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1495        done offline. A good approximation of the pressure load anomaly is
1496        necessary to avoid large initial adjustment processes underneath
1497        deep-reaching shelfice.
1498      - small fix in ISOMIP shelfice_thermodynamics
1499      - add more sophisticated thermodynamics of Hellmer (1989), this is
1500        now the default
1501      - give a few constants more intuitive names
1502    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1503      if bulk formulae are used in long integration (especially EmPmR). Turn
1504      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1505      if balancePrintMean, the imbalance that is substracted is printed to
1506      STDOUT.
1507    o fix bug (typo) in obcs_apply_eta.F
1508    o add a new package shelfice which enables us to model the circulation
1509      underneath shelf-ice with draughts of hundreds of meters.
1510     - works
1511     - to do: + include improved thermodynamics
1512              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1513                instead of new field kTopC
1514              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1515                instead of new field R_shelfIce and new code in ini_depth.F
1516                and ini_mask_etc.F?
1517              + adjust vertical mixing schemes?
1518    o seaice pkg:
1519     - add a cpp-flag to include a simple formula for a salinity dependent
1520       freezing point of sea water at the surface
1521     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1522       meridional stresses are now different (and hopefully correct)
1523    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1524       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1525       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1526    o pkg/diagnostics: add options and parameters for regional-statistics
1527       diagnostics ; define regions by reading a region-mask from a file
1528       (might add other options later)
1529    o pkg/bulk_force:
1530     - add option and parameters to use AIM surface-flux formulae.
1531     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1532       others forcing fields (defined in PARM05, parameter file "data") are loaded
1533       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1534     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1535     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1536     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1537       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1538     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1539    
1540    checkpoint58
1541    o add "--embed-source" option to genmake2 which, when the supporting
1542      tools can be compiled (as determined by genmake2) will turn on the
1543      embed_files package which then embeds the entire MITgcm source code
1544      (*.[fFhc] + Makefile) used for the build within the executable
1545      - requested by CNH but off by default
1546      - adds a paltry <9MB to the mitgcmuv executable in most cases
1547      - only writes the output when useEMBEDSRC in eedata is true
1548    o clean up 3-dim. relaxation codes:
1549      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1550      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1551      * Thanks to Tom Haine for testing!
1552    
1553    checkpoint57z_post
1554    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1555      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1556    o fix the pickup behavior for obcs in combination with ptracers
1557    o fix a bug in ptracers_external_fields_load
1558    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1559      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1560    o transfered surface NH pressure to eta field (if exactConserv).
1561    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1562         and update lab_sea output.txt file.
1563    o completing 3-dim. relaxation code: additional term
1564         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1565      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1566      * At compile time, in "EXF_OPTIONS.h" set
1567          #define  ALLOW_CLIMTEMP_RELAXATION
1568          #define  ALLOW_CLIMSALT_RELAXATION
1569      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1570          tauThetaClimRelax3Dim = 15552000.0,
1571          tauSaltClimRelax3Dim  = 15552000.0,
1572      * 3 cases:
1573          1) Use a constant-in-time 3-dim. field
1574          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1575          3) Real-time relax. to time-evolving prescribed field
1576    o Adding Laplacian-type smoothness constraint on
1577      initial and boundary (forcing) controls (ic, bc)
1578      * enable at compile-time via
1579        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1580      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1581      * Absolute scale somewhat unclear so far
1582      * no area weighting was included since no other cost term does so far
1583    
1584    checkpoint57y_post
1585    First step for a NLFS adjoint
1586    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1587    o new init. routines for calc_r_star, calc_surf_dr
1588    o still need to deal with ini_masks_etc
1589    o testreport seemed happy
1590    checkpoint57y_pre
1591    
1592    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1593    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1594    o add new offset feature to offline pkg (plus minor cleanup)
1595    o cfc fixes for final year of integration
1596    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1597      be in GCHEM_OPTIONS).
1598    
1599    checkpoint57x_post
1600    o fix testreport Pb in multiple test experiment.
1601    o cleanup our namelist syntax in verification:
1602      - make it more F95 standards compliant (some work still needed)
1603      - allows the vast majority of our tests to work with gfortran
1604    o Non-Hydrostatic:
1605     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1606     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1607    o Allow to apply AB on T,S rather than on AB(gT,gS):
1608     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1609     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1610       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1611     - need a "clever" read_pickup to restart from the other AB formulation
1612    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1613    o remove some unused variables (reduces number of compiler warnings)
1614    o adjoint
1615      * Disable useVariableViscosity for adjoint for time being
1616        (there are a number of extensive recomputations)
1617      * Initialize certain variables needed for adjoint
1618    
1619    checkpoint57w_post
1620    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1621                 fix the singleCpuIO RS version of MDSWRITEFIELD
1622       and add a WARNING if using globalFiles=T with multi-processors.
1623    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1624      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1625    o tracer advection scheme:
1626      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1627       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1628       was not very convenient).
1629      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1630       (further tests needed for the implicit DST & Flux-Limiter schemes).
1631    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1632      and sRef for convenience, handy, when you want to initialize
1633      ptracers in a large domain with a constant non-zero value. Also,
1634      untangle ptracers_init.F a little.
1635    
1636    checkpoint57v_post
1637    o change dome exp. to use variable viscosity in side-drag terms.
1638    o remove all the files from the cfc_offline test since they are now
1639      incorporated into tutorial_cfc_offline which has been producing
1640      identical results for a few days of testing
1641    o add new parameter: sideDragFactor to enable half-slip-side BC
1642      and change side-drag S/R to use viscosity from mom_calc_visc
1643      (can switch back by setting sideDragFactor=0.); affects results at
1644      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1645       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1646    o vorticity & strain are now computed without masking, to account for
1647      no-slip-side BC in variable viscosity calculation ; mask is applied
1648      anyway later on, before computing advection/coriolis terms.
1649    o modify exp4 to test new obcs support for reading from external files
1650      and for passive tracers
1651    o fix behavior of ptracers_monitor when monitor output is written to a
1652      netcdf-file; still not independent of monitor.F (writes in the same
1653      file).
1654    o change default value of tRef (put a uniform, meaningful value for ocean
1655      & atmos) and initialize sRef (was missing, as Martin mentioned).
1656    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1657      to be proportional to enstrophy dissipation length.  Thus,
1658       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1659      This is now consistent with Smagorinsky and with the manual.
1660    
1661    checkpoint57u_post
1662    o OBCS and PTRACERS: add open boundary support for passive tracers
1663      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1664        OB-values from file; this is not different from the way theta and salinity
1665        are treated
1666      - however, Orlanski-radiation conditions are not supported, and the model
1667        will stop if you use pTracers and Orlanski at the same time.
1668      - beefed up the rountine obcs_external_fields_load: now only those open
1669        boundary values are overwritten with values from files for which there
1670        are really files, otherwise the OB-fields remain untouched. This makes
1671        it possible to use different OBs at different ends of the domain (as
1672        with EXF)
1673    o reduce number of exch calls in shap_filt (s2).
1674    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1675      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1676    
1677    checkpoint57t_post
1678    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1679    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1680      same truncation, independent of the face number: affects affects several
1681      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1682    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1683      note that biharmonic viscosity + no-slip was not tested in any experiment.
1684    o fix bug in non-linear free-surf side-drag ; generate new output for
1685      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1686    o make mnc honor the writeBinaryPrec flag for most kinds of output
1687    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1688    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1689      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1690    o add brackets in multi-terms sum to get same truncation, independent of
1691      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1692      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1693    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1694      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1695      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1696      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1697      Suggested values of viscosity parameters found in mom_calc_visc.
1698      Many new viscosity diagnostics available.
1699    
1700    checkpoint57s_post
1701    o Add clearing-house for viscosity calculations, mom_calc_visc and
1702      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1703      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1704      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1705      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1706      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1707      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1708      ViscAhStrain and viscAhTension are now retired.
1709    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1710    o In response to JMC's bug report, genmake2 now ignores any soft-links
1711      that it finds in the *current* directory when searching for files.
1712      Soft-links found in any other source directories will still work as
1713      they did before.
1714    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1715      a C routine to unlimit the stack size
1716    o mnc-ify pkg/aim snapshot vars
1717    o mnc-ify pkg/land as requested by Daniel
1718    o various changes to mnc including:
1719      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1720      - output can now be grouped so that all files within a group
1721          change the ITER portion of their names in lock-step together
1722      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1723          and works with both EXCH1 and EXCH2 (but needs more testing)
1724      - writing works for all verification test cases w/ g77 on Linux
1725    
1726    checkpoint57r_post
1727    o make MNC variable initialization happen earlier
1728    o add diagnostics for (almost) each term of the momentum Eq.
1729    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1730    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1731    o remove MINIMAL_TAVE_OUTPUT option ;
1732      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1733    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1734      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1735    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1736    o add time-dependent SST, SSS control
1737    o cost terms in ecco/ modularized (new cost_generic.F)
1738    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1739    o new infrastructure for seaice model vs. obs misfits in seaice/
1740      * driver from the_main_loop.F is seaice_cost_driver.F
1741      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1742      * gradient check in Exp. 6a of natl_box_adjoint/
1743    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1744      (see README file)
1745    
1746    checkpoint57q_post
1747    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1748    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1749      - bug was reported by Jean-Michel and Ian Fenty
1750    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1751      update exp. cpl_aim+ocn output.
1752    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1753      Needed for high-res. runs with large global files
1754      to be able to limit tapelev size
1755    o Changed some tests for adjoint:
1756      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1757      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1758      * global_ocean.90x40x15/ back to default 3-level checkpointing
1759    o Modifications to enable scripted COMMON to MODULE conversion
1760      * verification/OpenAD/code/ has necessary scripts and description;
1761      * converts, compiles and runs successfully;
1762    
1763    checkpoint57p_post
1764    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1765    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1766      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1767    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1768    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1769      (was already the case for dissipation with mom_vecinv,
1770       and also the case for grad.PhiHyd when staggered-timeStep)
1771      This will allow to put dissipation out-off the AB time-stepping.
1772     Unfortunately, affects truncation error. Update output of exp. that "fails"
1773      (cg2d matching number) and leave the others for later: front_relax(10),
1774      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1775      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1776    
1777    checkpoint57o_post
1778    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1779      (2) its ready to be documented during the 20050801 DocFest
1780    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1781      for ideal_2D_oce and lab_sea on linux_ia32_g77
1782    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1783      in global1x1_tot/code_seaice_adj to access indices 32, 33
1784      (worth another tag)
1785    
1786    checkpoint57n_post
1787    o adding precip control xx_precip 32
1788    o adding swflux control xx_swflux 33
1789    o Replacing 10 forcing penalty cost routines by 1 generic.
1790    o Implementing partitioning in time-mean and variable adjustment
1791      for atmos. state.
1792    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1793    o in natl_box_adjoint:
1794      * updated exp 1 to 10
1795        (but does not have time-mean vs. variable split results yet)
1796    o updated global1x1/*_seaice_adj/
1797      to incorporate latest changes
1798    o enable useSingleCpuIO for mdsio vector routines
1799      (applies in particular to tapelev I/O)
1800    o removed inefficient K-loop in all active_file*control*.F
1801    
1802    checkpoint57m_post
1803    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
1804      and advect_cs (use EXCH-2 and standard cs-32 grid files).
1805    o pkg/exch2: filling of face-corner halo regions is optional
1806      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
1807    
1808    checkpoint57l_post
1809     tag before updating tutorials (pre-release-2)
1810    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
1811       for output and interpolation of input fields onto model grid)
1812    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
1813       Affects results of exp. rotating_tank ; update output.txt.
1814    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
1815          and taking the square quantity and/or using a fraction-weight field.
1816    o fix aim_diagnostics_init.F mate numbers.
1817    o add mnc output capability to diagnostics/diagstat and update
1818      our cvsignore files for the ACSII output generated
1819    
1820    checkpoint57k_post
1821    o lab_sea now uses diagnostics package and provides a suite of
1822      new EXF diagnostics output.
1823    
1824    checkpoint57j_post
1825    o exf
1826      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1827        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1828        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1829      * extended diagnostics output
1830        - now includes all EXF variables
1831        - hs, hl moved to common block
1832        - separate S/R for diagnostics, called after ctrl vector is added
1833        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1834        - EXFqnet contains true Qnet (i.e. includes qsw)
1835      * updated verif. lab_sea, global_with_exf
1836      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1837        to ensure that diagnostics sees a true EXFqnet
1838    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1839    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1840      several times with different frequencies.
1841    o mnc-ify the thsice package as requested by Daniel Enderton
1842      - the monitor--MNC output needs work
1843      - many attributes need to be added (most are currently blank)
1844    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1845      - many attributes need to be added (most are currently blank)
1846    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
1847    o add Sadourny like discretization to the 4th.O vorticity advection scheme
1848    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
1849      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
1850         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
1851    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
1852     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
1853    
1854    checkpoint57i_post
1855    o Diagnostics package was changed: diagnostic allocation is now deactivated
1856      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1857    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1858      add 1rst Order upwind vertical Shear.
1859    o add a quick fix for A/B checkpointing in OFFLINE mode
1860    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1861      end-run around the C/Fortran linking horror in eesup/src/timers.F
1862    o added pkg/runclock: allows user to terminate run based on wall clock
1863    o added non-hydrostatic scaling parameter: nh_am2
1864    o pkg/my82: futile attempt to make results compiler-independent by adding
1865      some "_d 0", etc. no effect.
1866    o for mnc output, fill the 'T' coordinate var with myTime and create a
1867      separate 'iter' variable for iteration count
1868    o pkg/diagnostics:
1869      add new capability: output of Global/Regional & per-level statistics ;
1870      tested against monitor output (including land & thSIce) on various exp.
1871    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1872    
1873    checkpoint57h_done
1874      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1875      data.diagnostics, data.gchem, data.ptracers) is done.
1876    
1877    o pkg/diagnostics: prepare for Global/Regional statistics.
1878      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1879    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1880      and rename it: DIFFERENT_MULTIPLE
1881    
1882    checkpoint57h_post
1883    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1884    o pkg/diagnostics: change output frequency, now in seconds (instead
1885      of Nb of iterations). This requires to change data.diagnostics.
1886    checkpoint57h_pre
1887    
1888    o in mnc, let the user create the output dir if both mnc_outdir_date
1889      and mnc_outdir_num are false
1890    o add fflags() to pkg/diagnostics which allows one to specify, on a
1891      per-file basis, the file precision [default behavior is unchanged]
1892    o added diagnostics to pkg/kpp, including computation of mixed layer
1893      depth based on a temperature/density criterion
1894    o updated verification/natl_box to test the new pkg/kpp diagnostics
1895    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1896    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1897    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1898      not mnc -- this mistake was found by JMC and is now corrected
1899    
1900    checkpoint57g_post
1901    o add Adams-Bashforth 3rd Order time stepping:
1902      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1903      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1904    checkpoint57g_pre
1905    
1906    o make lambda[Theta,Salt]ClimRelax spatially varying
1907      (default remains spatially uniform constant based on tau)
1908    o added new control variables
1909      * init. uVel, vVel, etanN
1910      * lambda[Theta,Salt]ClimRelax
1911    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1912      (suggested by G. Forget)
1913    
1914    checkpoint57f_post
1915    o add parameter "baseTime" = model base time = time at iteration zero
1916      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1917      account for baseTime shift
1918    o move Coriolis arrays from PARAMS.h to GRID.h
1919    checkpoint57f_pre
1920    
1921    o mnc-ifying the seaice package
1922    o introduced an alternative length scale calculation for use in the limiting
1923      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1924    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1925    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1926      as well as grad(vort3).  Made it compatible with both approximate form
1927      for the cubed sphere and full form of these gradients.  Added flag
1928      useFullLeith to select between approximate and full form.  
1929    o add "d0" in getcon.F to reduce differences between compilers/platforms
1930      update output.txt of exp. fizhi-gridalt-hs
1931    o change port_rand funtion to allow to set the seed.
1932    o fix obscure MNC bug involving conversion between reals and integers
1933      - it caused no problems with certain (eg. gcc, ifc) compilers but the
1934        new version is now more standards-compliant
1935    o adjoint-related modifications
1936      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
1937      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
1938      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
1939    
1940    checkpoint57e_post
1941    o Adding eddy stress controls a la Ferreira et al.
1942    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
1943    
1944    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
1945      update output.txt of exp. fizhi-gridalt-hs
1946    o add more "Z" dimensions and associated coordinate vars to MNC
1947    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
1948    o parameter calendarDumps: when set, approximate months (30-31 days) and years
1949      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
1950      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
1951      months and years.  Requires pkg/cal.
1952    o diagnostics: add pickup functionality
1953      - off by default for backwards compatibility
1954      - current version only uses MDSIO -- MNC will be added
1955    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
1956    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
1957    
1958    checkpoint57d_post
1959    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1960    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1961      output from the diagnostics package
1962    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1963    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1964      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1965    o add coordinate variables to the MNC output from the diagnostics package
1966    o change MNC-flags default value: true when useMNC=TRUE
1967    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1968      the ability (off by default) to read the grid information using MNC
1969    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1970    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1971    o do snap-shot diagnostics at the middle of the time-interval (instead of
1972      at the end).
1973    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1974      new test for AIM with thSIce + slab-ocean
1975    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1976    o move state variable diagnostics to the beginning of the time step ;
1977      (note: still needs some work specially for snap-shot diagnostics)
1978      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1979    
1980    checkpoint57c_post
1981    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1982    o generate new output.txt files on faulks with g77 & the new -ieee option
1983    checkpoint57c_pre
1984    
1985    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1986      update output.txt of exp. global_ocean.90x40x15
1987    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1988      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1989    o add saltFlux(+File) forcing capability with periodicExternalForcing
1990    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1991    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1992    o improvements for the MNC output from DIAGNOSTICS:
1993      - correct handling of the unlimitied dimension
1994      - all dims now have associated coordinate variables
1995      - variables located at U, V, and Corner ("Z") points are now written
1996        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1997        *all* data points are output
1998    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1999    o added pkg/seaice/seaice_monitor.F
2000    o mdsio_readfield.F can now read files visible only to master MPI process.
2001    o pkg/seaice: some test code for ice-modified ocean stress
2002    o exf_getffields interpolation defaults to bilinear for all scalar forcing
2003      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
2004      spurious negative numbers for precipitation and humidity.  Will cause
2005      some small numerical differences for integrations using pkg/exf/exf_interp.F.
2006    o pkg/ctrl/
2007      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
2008        May be enabled via doPackDiag
2009      *  introduce z-scaling of
2010         + gradient (doZscalePack) and
2011         + control (doZscaleUnpack)
2012    o pkg/mdsio/
2013      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
2014      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
2015    
2016    checkpoint57b_post
2017    o simplify options in diagnostics_fill arguments (remove weird combinations)
2018    o fix MNC coordinate variables so that they now contain per-face index
2019      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
2020      general, EXCH2 grids are only aligned to a "local" coordinate system
2021    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
2022    o Implement instantaneous output within pkg diagnostics:
2023      setting a negative frequency in data.diagnostics produces
2024     "snap-shot" output (as opposed to time-average if freq > 0)
2025    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
2026      NOTE: change ptracer diagnostics name: use 2 characters to work with
2027            more than 9 tracers. Add also diagnostics of advect & diffus flux.
2028    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
2029      becomes the coordinate variable for the 'T' dimension
2030    o add CF-style coordinate variables to MNC
2031      - just a first cut:  numbers are meaningless on the cubesphere and
2032        missing along the T axis but otherwise it works!
2033    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
2034    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
2035    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
2036      this is based directly on what the model compute, so that the content of
2037      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
2038    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
2039    o clean up build options files for SunOS, in particular
2040      - remove -traditional from xmakedepend
2041      - change -xarch=v9 to -xarch=native for f77
2042      - restore use of make (not gmake)
2043      - add CC=gcc if using g77
2044    o changes per discussion of AM, JMC, & EH3 today:
2045      - move redundant "grid" variables out of "state" -- in preparation of
2046        creating proper CF-style coordinate variables and in recognition
2047        that any/all grid variables can be easily copied (eg. w/NCO) from
2048        the grid files into any of the other NetCDF files
2049      - *always* output grid variables with MDSIO (this will eventually be
2050        changed)
2051      - output MNC grid file if useMNC is true
2052    o every instance of _END_MASTER() has been found and replaced with
2053      _END_MASTER( myThid ) in order to satisfy certain picky Sun
2054      preprocessors
2055    o re-arrange diagnostics pkg initialisation:
2056     - allow each package to extend the available diagnostics list
2057     - add some checking and fix small problems (multi-threaded, ...)
2058     - new S/R diagnostics_fill (replace fill_diagnostics):
2059       look through the short list of active diag. (instead of the long list)
2060       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
2061    
2062    checkpoint57a_post
2063    o this set of changes restores TAMC compatibility
2064      tested for global_ocean.90x40x15 adjoint on trough
2065      (what a pain)
2066    
2067    checkpoint57a_pre
2068    o some modifs in tools/build_options for sunos
2069    o call ctrl_pack for ctrl at end for optimcycle=0
2070    
2071    checkpoint57
2072    o add horizontal bi-harmonic viscosity for vertical velocity
2073      - new parameter viscA4W (defaults to viscA4)
2074      - affects only non-hydrostatic code
2075      - to be done: no-slip lateral boundary conditions
2076    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
2077    o implement Implicit Vertical advection for pTracers
2078    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
2079      (implemented also for implicit vertical diffusion & advection)
2080    o OBCS: extend application of tracer open boundary conditions
2081      to a strip beyond the boundary of width Olx/Oly
2082    o add call monitor to TAF set of required calls (flow directives)
2083      and include in natl_box_adjoint
2084    o untangle a few ifdefs related to cost, ctrl, autodiff
2085      untangel a few ALLOW_ECCO_OPTIMIZATION
2086    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
2087      (theta2, salt2 in ecco_cost_weights)
2088    
2089    checkpoint56c_post
2090    o OBCS as control variables
2091      - update ctrl_ad_diff.list, obcs_ad_diff.list
2092      - remove balance of obcs controls from default
2093      - fix index bug nobcs in ctrl_init
2094      - fix dummy fields filen in ctrl_pack
2095      - add dummy weights for obcs
2096    o lsopt: comment out fort.94 output
2097    o optim:
2098      - remove unnecessary header files
2099      - adjusted namelists
2100      - add xerbla.F to Makefile
2101    o exf:
2102      - multiple modifications of exf_check_range
2103      - unit change in exf_init_runoff from [m/year] to [m/s]
2104    o mdsio:
2105      - i/o-vector change debugLevel from debLevA to debLevB
2106    
2107    checkpoint56b_post
2108    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
2109      is called from DO_THE_MODEL_IO
2110      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
2111      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
2112      - clean up PTRACERS_WRITE_TIMEAVE a little
2113    o add another verification experiment that tests both the cfc-pkg and
2114      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
2115      reactive tendencies treated inline with regular timestepping
2116    o testreport previously did a lousy job of comparing small numbers, so
2117      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
2118      implemented in the little c-progam tmp_cmpnum.c which is embedded in
2119      testreport.
2120    o ptracers_monitor: bug fix for MPI
2121    
2122    checkpoint56a_post
2123    o GCHEM: finish reorganizating the package
2124      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
2125        (introduces another 3D-array for each passive tracer, but only if
2126        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
2127        gchemTendency is not needed because the timestep is done separately)
2128      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
2129      - GCHEM is now---more or less cleanly---separate from PTRACERS
2130      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
2131        so clear to me how that should be done in a general way.
2132    o CFC: improve formatting of output in CFC_ATMOS
2133    o PTRACERS:
2134      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
2135        that ALL experiments with ptracers enable can be checked. This makes
2136        GCHEM_MONITOR obsolete.
2137      - include a runtime parameter PTRACERS_monitorFreq that defaults to
2138        monitorFreq
2139      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
2140    o add PTRACERS (PTR0[1-5]) to testreport output
2141    o exf_check_range:
2142      * default changed to .TRUE.
2143      * will check values for niter0 if debLevA, every timestep if debLevB
2144      * STOP in exf_check_range if 'out of range'
2145      * range chosen generous to allow for potential extema
2146      TBD: a version with stricter range
2147           permitted range would be runtime parameters

2158      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
2159        be replaced by a 3D array that is computed before thermodynamics; for
2160        this, the tracer ID iTracer had to be included into the parameter list
2161        of ptracers_forcing
