7    checkpoint61l
8    o Overlaps had been forgotten in calculating ijk keys : fixed
9    o fix cyrus makedepend for gcc 4.4
10    o experiment fizhi-cs-aqualev20:
11      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
12      and generate new output. Note: new output is much closer to the old
13      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
14      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
15    o pkg/fizhi:
16     - change to avoid indices going deliberately over array-bounds
17     - remove unnecessary MPI stuff
18     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
19     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
20       does not go over array-bounds and therefore returns reliable output.
21     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
22       this S/R has 4 output arguments, which are used inside "get_alarm";
23       when it is called with the same variable "ndum" in place of several
24       output arguments, this produces weird side effect inside "get_alarm"
25      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
26       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
27       address) and produces error.
28    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
29    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
30       update lab_sea.lsr & lab_sea.salt_plume results
31    o pkg/seaice:
32      Major overhaul of the LSOR solver: change discretization from original
33      finite differences to finite volume. The old routine is still in the
34      file seaice_lsr.F and can be turned on with the CPP-flag
35      SEAICE_OLD_AND_BAD_DISCRETIZATION
36      Along with this change, the discretization of the strain rates is changed.
37      The same flag turns on the old discretization in seaice_calc_strainrates.F
38      All verification experiments with seaice are affected (except for
39      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
40      results by setting the above flag.
41      Further changes involve changes in defaults:
42      - ALLOW_FLOODING is defined and turned on by default
43      - SEAICE_advSnow = .true. is now the default
44      - SEAICE_advSalt = .true. is now the default
45      - SEAICE_advAge  = .true. is now the default
46      - SEAICE_clipVelocities  = .false. is now the default
47                                         (as per J. Zhang's recommendation)
48      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
49        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
50      - seaice_growth: replace computation of UG by a simple copy from wspeed
51    
52    checkpoint61k
53    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
54      seaice_lsr: fixed a few metric terms,
55                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
56                  add more debugging diagnostics
57      seaice_evp: removed superfluous many metric terms of FV discretization
58                  of stress divergence
59                  affects lab_sea, lab_sea.hb87
60      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
61                  of stress divergence for non-evp solver
62                  (this part is not tested anywhere)
63      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
64                  they were effectively only half slip
65                  affects lab_sea.hb87
66      updated all relevant verification experiments (except lab_sea//output_adm.txt
67        which was left over, but fails at level 7 & 6)
68    
69    checkpoint61j
70    o pkg/seaice: turn a few hard wired parameters into run time parameters
71    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
72      time in seconds as promised by the usints in seaice_monitor and exf_monitor
73    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
74      that are not cubed-sphere grids
75    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
76    o pkg/ctrl:
77      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
78    o non-hydrostatic (calc_gw.F):
79      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
80      update output of exp. global_ocean.cs32x15.viscA4
81    o remove backward compatibility for thetaMin,phiMin
82      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
83    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
84      interpolated wind field not only for curvilineargrid=.true., but also
85      for a rotated grid (rotateGrid=.true.)
86    o pkg/exf: add capability to bypass interpolation for runoff
87      by setting yet another CPP-flag
88    o eesupp/src, B-grid exchange:
89      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
90    o autodiff
91      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
92      allows to switch to single-prec common blocks;
93      corresponding switch occurs in tamc.h, integer isbyte
94      TAF store directivs "byte" and "kind" seem equivalent;
95      Most tamc.h have been updated correspondingly.
96    
97    checkpoint61i
98    o autodiff:
99      fix autodiff_sore/_restore indices for obcs
100      (spotted by I. Hoteit, M. Mazloff)
101    o pkg/autodiff, pkg/ctrl:
102      Add flag to reduce all tapelev I/O to single-prec.
103      In data.ctrl set
104        doSinglePrecTapelev = .TRUE.
105    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
106      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
107    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
108      real fresh water flux (not yet)
109    o pkg/mdsio & rw:
110     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
111     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
112    o pkg/flt:
113     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
114       init_fixed & ini_varia.
115     - clean-up & simplify linear interpolation S/R:
116       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
117     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
118     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
119     - add vert. coordinate & horiz. indices to output files.
120     - change vertical position in initial condition, from index to depth [m].
121     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
122       (easier to get to a curvilinear grid) ; delX,delY no longer used.
123    o pkg/ggl90: a few modifications:
124     - fix bottom boundary condition, and interpolation of KappaE
125       near top and bottom
126     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
127     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
128     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
129    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
130      (maintain temporary backward compatibility, until next checkpoint)
131    
132    checkpoint61h
133    o pkg/diagnostics with "periodic averaging diagnostics":
134      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
135    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
136    o pkg/obcs: fix loop ranges for balancing code
137    o pkg/flt:
138     - improve criteria for finding which tile owns a float.
139     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
140    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
141      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
142      with ocean biogeo)
143    o pkg/flt:
144     - do some cleaning and fix the restart ;
145     - add output.txt in flt_example/results to get this pkg tested.
146    o genmake2: add an EXTENDED_SRC option and flag.
147       for now, cannot be turned on on command line (only through genmake_local)
148    o pkg/mdsio: read/write vector:
149     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
150     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
151       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
152     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
153      (drop to 4 digits matching for grad). But this test does not look very
154      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
155    
156    checkpoint61g
157    o pkg/flt:
158      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
159       + make OPTIONS file more standard.
160      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
161      - fix _BYTESWAPIO CPP-Flag
162      - standard reading of file-parameter "data.flt"
163      - fix argument list of S/R FLT_RESTART
164      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
165    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
166    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
167      a still unfixed compiler/optimization bug
168    
169    checkpoint61f
170    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
171      update results of global_ocean.cs32x15.icedyn test.
172    o move getcon.F from model/src to pkg/fizhi.
173    o pkg/exf: add parameter for extrapolation of temp up to the surface
174       and option to prevent negative evap (in bulk_largeyeager04 only).
175    o Prather Advection scheme: fix tracer conservation for divergent flow
176      (e.g., when using NonLin Free-Surface).
177    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
178    o gmredi (Visbeck-variable-K):
179     - add more parameters to Visbeck-variable-K.
180     - use a 5 points average for dSigmaR in Visbeck-K calculation
181       (more "homogenous": same stencil and same weights as in dSigmaH)
182     - update output of ideal_2D_oce experiment.
183    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
184      (#undef REAL4_IS_SLOW)
185     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
186       coordinate variable
187     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
188       (surface forcing fields), removes some of the functionality
189     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
190     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
191       probably not all: copy _RS surface flux fields to RL field before
192       calling DIAGNOSTICS_FILL
193     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
194       real*4 (CALL EXCH_*_RS) versions.
195     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
196       (generate new output).
197    
198    checkpoint61e
199    o gmredi (Visbeck-variable-K):
200      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
201      - change computation of Visbeck-K where Slope > Smax :        
202        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
203        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
204    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
205      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
206    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
207    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
208      does not become too large (to avoid precision problems in implicit-diffusion
209      solver); update ideal_2D_oce output.
210    o pkg ggl90:
211      - in ggl90_cal.F: compute only one set of visc/diff, used to
212        step forward TKE/T/S/momentum
213      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
214        have Prandlt =1)
215    o gmredi (fm07):
216      - add lower limit on Transition layer thickness + lower limit on 1/lambda
217      - allow to set few more params from data.gmredi
218    o pkg ggl90:
219          - add missing sqrt(2) factor in computation of mixing length
220            scale in ggl90_calc.F
221            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
222    
223    checkpoint61d
224    o adjoint modifs
225      - adapt to new field rhoInSitu
226      - allow to revert from StoreDynVars2D, StoreDynVars3D
227        to individual fields
228        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
229    o store 3-D (in-situ) density in commom block (DYNVARS.h)
230     - save 1 rho computation.
231     - no longer modify T & S inland when using down_slope pkg.
232    o gad_som : allow to switch to SOM advection for T & S without corresponding
233      pickup files (using new S/R: MDS_CHECK4FILE).
234    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
235      (for useSingleCpuIO to work in multi-threaded)
236    o pkg/shelfice:
237     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
238       with SHELFICEtopoFile in data.shelfice
239     - move code for reading ice shelf topography and modifying hFacC into separate
240       subroutines of the shelfice package
241     - separate initialisation of "fixed" and "variable" variables
242     - kTopC is not (yet) replaced by kSurfC, although this is possible
243    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
244    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
245      and rename:
246      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
247      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
248    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
249    
250    checkpoint61c
251    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
252      to add mass source/sink of fluid in the interior (3-D generalisation
253      of oceanic real-fresh water flux).
254    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
255    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
256    o new pkg: down_slope
257      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
258      - presently, modify T & S inland (dwnslp_calc_rho.F).
259        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
260      - implementation for ocean in P-coords not tested.
261      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
262    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
263      (to facilitate conversion of oceanic pkg to p-coordinate).
264    o change FIND_RHO to FIND_RHO_2D :
265      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
266    o new pkg: cheapaml
267    
268    checkpoint61b
269    o exch2:
270      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
271      - no longer depend on the order sequence (N,S,E,W).
272      - 3rd exchange no longer needed (tested with 24 tiles).
273      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
274      - exch_UV_A-grid readily available (but not yet tested).
275      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
276      (both are no longer needed) in exch_uv: no effect in forward run; but
277       get truncation error differences with adjoint exch.
278    o exch2:
279     - change index-bounds storage (moved from target to local tile,
280       more intuitive this way) ; rename/remove some variables.
281     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
282    
283    checkpoint61a
284    o exch2/matlab-topology-generator:
285      fix bug in index bounds for N-S internal exchange (hard to tell if this
286      had any effect on the solution).
287    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
288      is exceeded
289    o testreport: modify syntax of awk, so that it works also with
290      awk, and not only with nawk and gawk
291    
292    checkpoint61
293    o autodiff
294      Change default for TAF usage by removing argument '-nonew_arg'
295      This changes TAF subroutine argument list (ordering of active var.)
296      Omission of this flag leads to incompatibility w.r.t. TAMC
297      To restore TAMC-compatibility, need following modifs:
298      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
299      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
300      Tested TAF version is 1.9.22
301      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
302    
303    checkpoint60
304    --->>> This is the last checkpoint for which generating the adjoint
305    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
306    --->>> by default.
307    --->>> Future checkpoints will ommit this flag by default.
308    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
309    o pkg/grdchk: Add gradient check to etan0 perturbations.
310    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
311    o pkg/autodiff: more flexibility in zeroadj.
312      model/src: modifying do_oceanic_phys.F accordingly.
313    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
314    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
315      special setup of gmredi for which the adjoint is stable
316      enough for parameter optimization.
317    o bridging the gap between eddy stress and GM.
318      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
319          along with a change in CPP option (now ALLOW_EDDYPSI).
320      -> when using GM w/ GM_AdvForm:
321          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
322          is applied either in the tracer Eq. or in momentum Eq.
323          depending on data.gmredi (intro. GM_InMomAsStress).
324      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
325      The key modifications are in model/src/taueddy_external_forcing.F
326      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
327    
328    checkpoint59r
329    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
330      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
331      fix option to read coriolis(@ cell-corner) from files with CS-grid.
332    o pkg/mnc: add some attributes to standard 1D-coordinate variables
333    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
334      mass points, when using mnc for output
335      - add runtime parameter (missing_value, missing_value_int) to override
336        default (which is the value of getcon('UNDEF'))
337    o pkg/mnc: prepare mnc for the actual use of missing values with the
338      diagnostics package: small fix in mnc_cw_readwrite.template and more
339      initialisation of never used fields
340      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
341      versions
342    o pkg/thsice/thsice_ini_vars.F added default initial values so that
343      thermodynamics sea ice solver does not blow up when some initial fields
344      are missing.
345    o move from external_forcing_surf.F to ini_forcing.F
346      the p-coord. hack consisting in using pLoad to set phi0surf ;
347      update output of tutorial_global_oce_in_p (affected @ truncation level).
348    o Freshen up a bit hs94.1x64x5, notably:
349      remove rotationPeriod and tRef=5*0. (adjoint only), and add
350      exactConserv=.TRUE.
351    o pkg/generic_advdiff:
352      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
353      applies to files where Temperature & Salinity 2nd Order moments are used.
354    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
355      this uses a dynamically allocated internal state data structure
356      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
357      and requires a fortran 90 compiler
358    
359    checkpoint59q
360    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
361       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
362    o Refresh tutorial_global_oce_biogeo, notably:
363      - change bathymetry (put back seamounts in ACC, use hFacs)
364      - change EOS (POLY3 --> JMD95Z)
365      - use Bryan-Lewis vertical diffusivity
366      - use multidimensional advection
367      - remove old virtual virtual in dic pkg, now done through ptracer pkg
368      - change a couple of parameters in dic pkg
369    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
370    o pkg/obcs: change default to OBCSfixTopo = .true.,
371      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
372      - replace "debugMode" with "debugLevel .GE. debLevB"
373    o implementation of TAF directives for gchem,cfc,dic
374    o remove "exp5" (replaced by tutorial_deep_convection).
375    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
376      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
377      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
378      --> changes results in exp4, seaice_obcs
379    o tutorial_deep_convection :
380      update the set-up and increase resolution and domain size ; start
381      from pseudo initial conditions = output at t=120mn in order to see
382      something happening when running testreport.
383    o pkg/seaice: add os7mp as an advection scheme
384                  add check for advection schemes
385                  add a flag for restoring T and S underneath sea ice
386    o pkg/my82: add netcdf-support and diagnostics
387    o thsice pkg:
388      - Now hsMax limits snow height by turning it into ice following
389        flooding scheme (and now conserving energy)
390      - Slight rewriting of the formula in thsice_calc_thick.F
391      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
392      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
393    
394    checkpoint59p
395    o gchem / dic / cfc :
396      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
397      - add new parameter files: "data.dic" & "data.cfc" ;
398      - various re-arrangement in initialisation & header file ;
399      - fix tutorial_global_oce_biogeo for multi-threaded test.
400    o pkg/dic: test for "pickup_dic" file when restarting ;
401      if no pickup-file, can restart with a re-initialised pH (same as it did
402      before) providing pickupStrictlyMatch is set to False.
403    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
404      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
405    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
406      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
407    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
408     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
409       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
410    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
411       scheme to use for vorticty-term ;
412     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
413       (with default selectVortScheme, return to original discretisation)
414     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
415    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
416    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
417      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
418      also fix diagnostics VISCAHW & VISCA4W.
419    
420    checkpoint59o
421    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
422    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
423      move a few statemens out the main loop into separate loops
424    o pkg/shelfice:
425      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
426        (kg/m^2/s), does not break tests, because in verification/isomip,
427        rhoConstFresh=rhoConst (by accident)
428      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
429      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
430        new file model/src/seawater.F, so that they are available for all pkgs.
431      - convert potential temperature into in-situ temperature. This changes the
432        isomip tests => update tests
433    o add a flag writePickupAtEnd (default=true) to be able to suppress
434      writing a pickup at the last timestep
435    o tools/mpack-1.6 :
436      - disable automake (not working) and autoconf (not needed).
437      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
438        also cleaner with much less compilation warnings.
439    o pkg/profiles:
440      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
441      (for "less than 32 characters name" compiler requirement)
442    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
443      conditions that have a different sampling frequency than S/T/U/V obcs
444    o pkg/diagnostics (stats-diags):
445      - fix global Min/Max in case 1 processor get only empty tiles
446    o genmake2: replace (4 times)
447         make genmake_tc_1.o >> genmake_warnings 2>&1
448      with
449         COMM="$CC $CFLAGS -c genmake_tc_1.c"
450         echo $COMM >> genmake_warnings
451         $COMM >> genmake_warnings 2>&1
452      to make genmake2 always see the value of CC as specified in the optfile.
453    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
454      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
455      - modify verification advect_cs test to test SOM-advection on CS-grid.
456    o pkg/ctrl:
457      - Rewrite of ctrl_map_ini_ecco.F,
458        introducing a generic routine (ctrl_map_ini_gen.F).
459      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
460    
461    checkpoint59n
462    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
463      number in dedicate array "hdiag":
464      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
465        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
466      - many small changes (integer format) for large number of diagnostics
467      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
468        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
469    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
470      usingSphericalGrid, this allows to define the rotated grid coordinates
471      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
472      geographical coordinates according to the inverse of the rotation defined
473      by the Euler angles, so that Coriolis parameter and online-interpolation by
474      exf works with the geographical coordinates on XC/YC/XG/YG.
475      Naturally, this feature does not work with all packages, so some
476      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
477      profiles), because there the coordinates are assumed to be regular
478      spherical grid coordinates.
479    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
480      - introduce isopycnal diffusion coefficient control.
481    o tools/adjoint_options:
482      - additional control vector components.
483    o pkg/mnc: have mnc create marginally meaning full coordinate variables
484      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
485    o pkg/mypackage:
486      - add example of read/write pickup for state-var ;
487      - add entry points to the main code for state-vars diags & write-pickup.
488    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
489      transitions for useExfYearlyFields
490      - add new subroutine that determines the file to read from for
491        use*YearlyFields = .TRUE. and .FALSE.
492      - add a verification experiment to global_with_exf that tests
493        useExfYearlyFields with USE_EXF_INTERPOLATION defined
494    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
495      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
496      subroutines (which could be generated from a template, because they are
497      almost identical), for now they are included in obcs_prescribe_read.F for
498      simplicity
499    o pkg/exf:
500      - add a little more diagnostic to exf_interp_read (in analogy to
501        mds_read_field, can be turned off with debugLevel < debugLevA=1)
502      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
503        ugly but fast by unrolling short inner loops, inserting a unroll=8
504        directive in routine lagran, and splitting a loop and making do while the
505        outermost loop (the latter requires the intoduction of index arrays)
506    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
507    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
508      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
509    o verification/seaice_obcs: updated for restart test and latest options
510    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
511      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
512      for now this is only available for the C-grid code and also within
513      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
514    
515    checkpoint59m
516    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
517      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
518    o gad_som : fix flux output (& diagnostics) to have same units as other  
519      advection scheme fluxes (was previously multiplied by deltaT).  
520    o added verification/seaice_obcs both to test seaice open boundaries
521      and to provide an example matlab scrpt for generating them
522    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
523    o pkg/salt_plume: clean up salt_plume_frac.F to
524      remove redundancy in PlumeMethod 1 and 4
525    o pkg/kpp: added saltplume diagnostics
526    o pkg/obcs and pkg/seaice:
527      - do not set uice and vice to zero when OB*icefile are unspecified
528      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
529      - moved seaice tracer obcs after call to seaice_growth
530    o pkg/salt_plume: added various options for salt plume depth
531      criterion and for vertical distribution of the salt
532    
533    checkpoint59l
534    o pkg/ptracers: new version of ptracers pickup:
535      read meta file and write only fields which are needed to restart.
536      ( same logic as main pickup file ; also using pickupStrictlyMatch )
537    o pkg/seaice:
538      - add timescale for melting due to warm mixed layer as a means of
539        setting SEAICE_availHeatFrac more conveniently
540      - add a CPP-flag/runtime parameter check for flooding algorithm
541      - reformulated availHeat in seaice_growth.F to be independent of AREA
542    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
543      unit changes
544    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
545    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
546      SX vector computer.
547    o pkg/seaice:
548      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
549        seaice forcing fields can now be read only through pkg/exf
550      - removed some unused halos
551    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
552    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
553      or U/VICE from U/VWIND before computing U/VSTRESS
554    
555    checkpoint59k
556    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
557      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
558    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
559      all experiments pass when compile with un-initialised var. checking option.
560    o added pkg/salt_plume
561    o script to test restart (for now, in MITgcm_contrib/jmc_script)
562    o pkg/seaice: new read/write pickup version.
563      read meta file and write only fields which are needed to restart.
564      ( same logic as main pickup file ; also using pickupStrictlyMatch )
565    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
566    o lab_sea.hb87: modify the domain & update output.hb87.txt :
567      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
568      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
569      process. Fixed here by closing the domain at the Northern boundary.
570    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
571    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
572      a set of consecutive levels in/from a 3-D array.
573    o pkg/ptracers:
574      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
575      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
576    
577    checkpoint59j
578    o in pkgs: dic, obcs, offline, rbcs:
579      standard way to compute coeff. for time interpolation between 2 time reccords
580      which retains full precision (& make results less dependent on compiler).
581      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
582    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
583      packages instead of reading ice cover and wind speed separately
584    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
585     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
586      to allow to compile customized code before the update)
587    o cleaning-up:
588      - fix CPP instruction syntax in pkg/obcs
589      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
590        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
591      - fix some threads issue in IO parts.
592    o pkg/dic:
593      - add tons of "_d 0" (--> much better testreports !)
594       and then update outputs of tutorial_global_oce_biogeo
595    o pkg/mom_fluxform:
596      add a special version of momentum advection intended to conserve momentum
597      next to a bathymetry step or a coastline edge. (default = off = #undef)
598    o new read/write pickup version:
599      - for now, only implemented for main (mdsio) pickup file.
600      - write out only what is needed to restart; merge pickup_nh , pickup_ph
601        and main pickup together.
602      - read meta file; read only what is needed to restart; stop if a field
603        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
604        if it make sense (even if the restart is not perfect).
605      - if no meta file, assume that pickup to read corresponds exactly to
606        a pickup that would currently be written.
607      - read pickup written in the old format (until checkpoint59i) if it
608        recognizes an old meta file (no field-list).
609      - add a meta file in exp. which starts from a pickup: 2 cases:
610        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
611         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
612        b) a meta file describing the content of the associated pickup file
613         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
614    o pkg/mdsio & pkg/rw:
615      - new routine to read a meta file ; new set of routine to read
616        Multiple-fields file (with meta file).
617    o added open boundary conditions capability for seaice
618        HSNOW, HSALT, UICE, and VICE
619    
620    checkpoint59i
621    o adjoint:
622      * fix multiDimAdvection adjoint
623        (partial recomputation problem by TAF for fVerT(:,:,kDown)
624        and comlev1 size definition (maxpass vs. max. number of tracers)
625      * verification/global_ocean.90x45x15 adjoint now tests
626        NLFS and multiDimAdvection using DST3 (=30)
627      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
628    o pkg/kpp: add "_d 0" to real constant (if missing);
629      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
630      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
631    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
632      for internal parameters related to restart process (formerly from PARAMS.h)
633      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
634    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
635      as argument. (only atm2d & obcs write_pickup have not yet been updated)
636    o pkg/monitor:
637      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
638      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
639      - account for deep Atmosphere factor and density factor (anelastic)
640    o added open boundary conditions capability for seaice HEFF and AREA
641    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
642      thermodynamics
643      - requires a little reorganization, which affects the testreport results
644        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
645        so that now the conservative form is tested
646      - add a few comments
647    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
648    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
649    o add new diagnostics to seaice: advective, diffusive fluxes (only for
650      multidim-advection, for scheme 2 they are not filled) and transports,
651      thermodynamic growth rates
652    o change units of EmPmR (inside the code, + within coupling interface)
653      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
654      Affects results @ truncation level (cg2d match) and update output of
655       experiments: lab_sea(6), global_ocean.90x40x15(10),
656      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
657      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
658      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
659      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
660    
661    checkpoint59h
662    o pkg/exf:
663      - improve vectorization by moving if-statement out of loops in
664        exf_mapfields, exf_radiation
665      - exf_bulkformulae.F: introduce 2D fields and vectorize code
666    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
667    o testreport:
668      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
669        monitor & update offline_exf_seaice exp. output.
670      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
671    o pkg/seaice:
672      - bug fix in the evp solver: boundary conditions were affected be
673        masking of zMax/zMin (changes results)
674      - minor bug fix in boundary conditions in seaice_calc_strainrates
675        (changes results for no_slip)
676      - seaice_lsr.F: make interpolation of eta dependent on boundaries
677      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
678      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
679        stress formulation and no-slip boundary conditions
680    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
681      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
682    o pkg/seaice: a first HSALT time stepping equation has been checked in
683    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
684      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
685      without requiring DO-IF statements
686    o pkg/thsice:
687      use continuous power-law function for partition of energy between lateral
688      melting/freezing and thinning/thickening ; old code using step function
689      still available with #undef THSICE_FRACEN_POWERLAW
690      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
691    o testreport: change AD testing : check against results/output_adm.txt
692      using same scripts as for forward test.
693    
694    checkpoint59g
695    o adjoint testing: in preparation for changing testreport:
696      - output format: cost and grad written on separated lines
697      - ad output results in directory "results" (instead of "results_ad")
698    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
699    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
700    o pkg/ecco: allow user defined cost function contributions
701    o testreport:
702      Allow to choose (per experiment) the list of tested output variables
703       and the main variable (used to issue a pass/FAIL ) ;
704      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
705      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
706      Also modify printing of summary:
707       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
708       b) echo the list of tested variables in the individual summary.txt of
709          each experiment.
710    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
711      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
712      (but still depend on the tile decompostion of the domain).
713    o pkg/seaice: change a discretization detail to make the B-grid code
714      "more symmetric". This change is likely to remove all "ridges/leads" that
715      where quasi-aligned with the grid in B-grid solutions. It may also be
716      the solution to the stress coupling issues with the B-grid.
717    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
718      remove .cvsignore from input dir. (since testreport no longer run here).
719    o pkg/thsice:
720     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
721     - fix reshaping of sea-ice just after advection:
722       melt all the ice only if ice-volume is too small.
723     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
724       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
725     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
726    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
727      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
728    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
729      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
730      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
731      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
732      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
733      -> update output.txt
734    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
735     this affects truncation error: -> update output.txt of exp:
736      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
737      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
738    
739    checkpoint59f
740    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
741    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
742      a bounded range (in forward mode)
743    o pkg/ecco, ctrl, autodiff and mom_common:
744     internal parameter controls, completements of implementations
745    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
746    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
747      (not seem any difference in testing results).
748    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
749       at face corners.
750    o pkg/generic_advdiff:
751     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
752      loop range indices for computing vertical advection tendency
753      and do the calculation in the interior only (no overlap) ;
754      for now, only implemented for SOM advection (to save CPU time).
755     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
756    o exch2 adjoint
757      First set of changes:
758      - add exch2 hand-written adjoint templates
759      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
760        This will require cleanup in pkg/autodiff/*.F
761        (changed routines currently kept separate in verif. code/)
762      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
763        that used to hide exch2 or cubed-sphere specific code
764        (commented via 'cph-exch2')
765    o pkg/seaice
766      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
767    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
768       output of global_ocean.cs32x15.thsice .
769    
770    checkpoint59e
771    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
772      for B-grid vector (not yet tested) and C-grid vector (<- only used
773      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
774    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
775      (#ifdef ALLOW_SALT_PLUME)
776    o gather_2d/scatter_2d: removed halo regions
777    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
778      scheme and the corresponding test case (under front_relax dir). For now,
779      only available with Skew-flux form and not yet tested in realistic set-up.
780      adjoint: store directives updated, but gradient checks deteriorated,
781      so maybe GM/Redi adjoint is now broken.
782    o seaice adjoint
783      * add AREA, HEFF, HSNOW as control variable
784        (should not change lab_sea results)
785      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
786    o pkg/seaice:
787      * added computation of saltFlux in seaice_growth;
788        For time being, sea ice salinity is assumed constant
789        contribution of snow flooding to freshening of sea ice is neglected.
790        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
791        defaults to 0.0 in order to maintain backward compatibility.
792        Typical values for SEAICE_salinity are 4 to 10 g/kg.
793      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
794      * added SEAICE_availHeatFrac, which specifies fraction of surface level
795        heat content used to melt or grow ice
796      * commented out cap of HICE: it helps keep ice thinner
797      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
798      * applied OBCS T/S mask to HEFFM sea ice mask
799    
800    checkpoint59d
801    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
802     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
803     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
804    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
805     and change default value of parameter "GM_Small_Number";
806     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
807       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
808       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
809    o pkg/ecco: cost function when applying pkg/smooth to controls
810    o pkg/ctrl: add forcingPrecond run time parameter
811    o pkg/seaice:
812     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
813     - fix bug in metric terms of u-equation in LSR solver (implicit part),
814       changes verification/lab_sea
815     - rearrange implicit part of u-equation in LSR solver to make it easier to
816       read, understand, and debug. This causes changes at the truncation level.
817     - fix (serious) bug in the boundary conditions (sign error in the implicit
818       part) of the LSR solver. Changes all LSR results.
819     - fixed problem with HSNOW initialization to avoid thick snow when AREA
820       is initilized with small values - does not change lab_sea results.
821     - added HsnowFile initialization capability
822    o pkg/smooth: addition to model/src and pkg/ctrl so allow
823     initialization of pkg/smooth and application to control vector
824    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
825    o dependencies: pkg/profiles requires pkg/cal
826    o pkg/profiles:
827     - added option ALLOW_PROFILES_GENERICGRID
828         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
829         that interpolation information (grid points and coefficients) is provided
830         within the netcdf input files.
831         -> sample matlab scripts can be found in MITgcm_contrib/gael
832         that allow you to prepare netcdf input files.
833     - also modified: cleaner include statements, cleaner error print statements,
834       cleaner stops when error, and more tests of the netcdf input files consistency.
835    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
836    o pkg/seaice:
837     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
838       requires a new routine: seaice_diagnostics_fill.F
839     - make sure that seaice does not move if not forced (pressure replacement
840       method, Hibler and Ip, 1995), changes results
841     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
842     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
843       It is turned off by default (=-1.), because it changes the results.
844     - make it possible to read AREA from a file, too.
845    
846    checkpoint59c
847    o add S/R and diagnostics for oceanic mixed-layer depth
848    o move GMRedi call after all vertical mixing schemes (including KPP)
849    o pkg/thsice:
850     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
851      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
852    o pkg/obcs:
853     - bug fix for balance code
854    o pkg/seaice:
855      - allow values of SEAICE_elasticParm > 1
856      - add new parameter SEAICE_evpTauRelax as an alternative
857        to SEAICE_elasticParm
858      - make lsr boundary conditions free slip (by default), changes result
859      - add code for no slip boundary conditions for lsr
860      - set minimum of zeta to zero (and not 4e8) (changes results)
861      - add a cap on AREA after advecting AREA if seaice_growth is not called
862    o change calculation of Visbeck K:
863      - no longer depend on tapering scheme; instead, compute slope (limited
864        by GM_maxSlope). this is equivalent to what was comuted before with
865        clipping or linear tappering.
866      - fix vertical averaging (wrong by 1/2 level)
867      - leave the old version (but will not be maintained) within
868        #ifdef OLD_VISBECK_CALC / #endif
869      - update output of exp. ideal_2D_oce
870    o change error catch in calc_r_star to improve vectorization
871    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
872      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
873    o adjoint:
874      Re-organized adjoint checkpointing according to Matt Mazloff
875      (but with modifs/completions/cleanups)
876      Storing is now bundled into large arrays to optimized I/O
877      (and second step in cleanup of the_main_loop)
878    
879    checkpoint59b
880    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
881      - export/import (between ocean & coupler) fields needed for ocean DIC.
882    o pkg/seaice:
883      - get rid of three more exchanges seaice_calc_viscosities (required
884        different loop boundaries in seaice_lsr and seaice_ocean_stress)
885      - bug fix in seaice_ocean_stress (update of lab_sea required)
886      - reduce loop boundaries to necessary minimum also in seaice_evp
887      - go back to the old way of computing deltaC/Z as the adjoint likes that
888        better
889    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
890      passive tracer to an Age Tracer) + update output.txt
891    o pkg/exf:
892      - implement A-grid / C-grid selection for wind-stress input files.
893      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
894      for now, in exf_bulk_largeyeager04.F only :
895      - change implementation for case where windspeed + 2. components wind-stress
896        are read-in. AND use rhoConstFresh to convert evap.
897    o pkg/seaice:
898      - use correct EXCH_UV for wind-forcing (on A-grid).
899      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
900        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
901    o pkg/exf:
902      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
903      EXF_INTERPOLATION:
904      - merge global_with_exf/code version of exf_interp_read.F
905        to the main code ;
906      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
907        reading the file ; Important: This options needs to be defined to recover
908        previous code.
909        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
910      - no longer loose real*8 precision along the way when using exf_iprec=64.
911    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
912      - change discretisation of evp-solver in order to avoid another exchange
913        (changes lab_sea) and clean up a little
914      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
915        help the adjoint (this also changes the results slightly)
916      - add a few "_d 0" where they had been missing in seaice_evp.F
917      - cleaning up: remove unused seaice_calc_rhs.F
918    o pkg/exf: some cleaning-up:
919      - change various "constants" into runtime parameters
920      - cleaned-up Large&Yeager04 routine which should eventually
921        replace exf_bulkformulae.F (changed names of S/R and CPP)
922        and merged various ALLOW_ATM_WIND options
923     only used with thsice pkg (in thsice_get_exf.F):
924      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
925        which are used when useStabilityFct_overIce=TRUE (= the default)
926      - change default values of ice & snow emissivity and scale downward LW
927        by ice & snow emissivity.
928    o pkg/thsice:
929     fix few little problems, in thsice_calc_thickn.F:
930      - growth vertically (and not laterally) if iceFrac == iceMaskMax
931      - melt only laterally if hIce < hThinIce (as the comments say)
932      and in thsice_extend.F:
933      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
934      - start to form ice as soon as the minimum ice-volume is reachable.
935     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
936      and cpl_aim+ocn
937    o pkg/kpp
938     - move computation of surface related input fields to KPP into a new
939       subroutine kpp_forcing_surf.F
940     - remove wrong (within bi,bj loops) EXCH calls.
941     - little cleaning (add argument myThid in last position, cvs header ...)
942     - for now, fix conservation problem by exchanging KPPviscAz (may not
943       be the best fix)
944    o pkg/seaice
945     - check for inconsistent evp parameter/cpp-flag combination
946     - remove leftover errIO flat for obsolete name list error handling
947    o OpenAD
948     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
949    
950    checkpoint59a
951    o pkg/seaice: some parameter clarifications and a little bit of clean up
952    o pkg/thsice: rename run-time parameters:
953       himin       -> hIceMin
954       himin0      -> hThinIce
955       hihig       -> hThickIce
956       i0          -> i0swFrac
957       transCoef   -> bMeltCoef
958       frac_energy -> fracMelting
959      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
960       with default values (for now) that do not change the results.
961      remove old version of thsice vars advection in pkg/seaice.
962    o in FFIELDS.h:
963      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
964      - make pLoad & sIceLoad always available (but still only used if
965         ATMOSPHERIC_LOADING is #define).
966    o pkg/kpp: replaced _KPP_RL with _RL
967    o bug fixes for vertical diffusivity computations when both KPP and
968        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
969        are no longer updating the vertical diffusivity array
970        (passed as argument) but are (re-) setting those arrays.
971    o pkg/seaice: fix bug in evp solver, while doing that
972      - change (improve?) discretization of stress computations for both
973        cgrid-lsr and evp solver
974      - add a new routine to compute strain rates
975      - the above changes lab_sea results
976      - add no slip conditions for evp solver (off by default), lsr-version
977        may follow
978      - fix exchange for shear at Z-points (does not change lab_sea)
979      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
980        (to force the user to pick a time step since there is not "safe" way
981        of choosing it)
982      - add principal stress diagnostics
983      - rearrange fields for evp a little to avoid having to call a: too many
984        exchanges and b: exchanges for stress trensor components which we do
985        not have.
986      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
987        of evp, complete rewrite for lsr case (latter is does not yet work
988        in all cases)
989    o pkg/kpp: add code to have mixing in shelf ice caverns
990      - add myThid to all kpp routines (long overdue)
991    
992    checkpoint59
993    o pkg/exf:
994      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
995        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
996      - move exf header files from lower_case.h to UPPER_CASE.h ;
997        add missing cvs Header & Name
998      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
999      - add namelist param. selectStressGridPosition, exf_monFreq
1000      - retire many _CLIM routines, and remove data.exf_clim
1001        + params moved to data.exf
1002        + climsst, climsss now handled by exf_set_gen, i.e.
1003          climss?period=0 refers to constant field,
1004          climss?period=-12 to monthly forcing
1005      - split up namelists in data.exf
1006    o pkg/seaice:
1007      - remove seaice_exch and seaice_exch_uv
1008      - remove superfluous exchange of theta
1009      - add myThid to seaice_budget_ocean/ice
1010      - add new interface for atmospheric wind forcing (C-grid only)
1011        + new routine
1012        + two new field (taux, tauy for stress over ice)
1013        + removed one global field (DAIRN) for C-grid case only
1014    o pkg/thsise
1015      - 2nd set of modifs for thsice adjoint in conjunction with exf
1016    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
1017    
1018    checkpoint58y_post
1019    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
1020      vertical diffusivity, similar to that in MOM4; turned on using
1021      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
1022      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
1023    o Added capability for 3D specification of background vertical diffusion
1024      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
1025      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
1026      "data" file that contains the 3D vertical diffusivity coefficients.
1027    o ice dynamics (pkg/seaice) with thsice thermodynamics:
1028      - add code within pkg thsice to advect & diffuse sea-ice fields
1029      similar to (and will replace) what has been added in  seaice_advdiff.F,
1030      but: - conserving Mass, Heat & Salt.
1031           - better when using non-linear advection scheme (not yet fully tested)
1032           - can also be used in atmospheric set-up (for now, only the diffusion).
1033    
1034    checkpoint58x_post
1035    o IO option for global-file compact format:
1036      - add options when generating topology (utils/exch2/matlab-topology-generator)
1037      - add I/O capability (pkg/mdsio).
1038      - adapt utils/matlab/rdmds.m to read this format.
1039      for now long-line format not yet supported by pkg/mdsio (& exch2).
1040    o shelfice: add a few diagnostics
1041    
1042    checkpoint58w_post
1043    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
1044      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
1045      (and replace horiVertRatio in NH code).
1046      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
1047                         and tutorial_plume_on_slope (sensitive to truncation)
1048    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
1049      directly to drive seaice model (C-grid only)
1050    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
1051     - reintroduce computation of wind from stress,
1052     - compute tau (in exf_bulkformulae.F) from windstress averaged to
1053       mass points to avoid tau = 0
1054     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
1055    o rdmnc.m: make it work with "global" files created with gluemnc
1056    o rdmnc.m : some improvements in dealing with singleton dimension
1057      (tested on all testreport mnc output files).
1058    o genmake2: disable pkg/profiles if netcdf test fails.
1059    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
1060    o move call to cal_readparms up to make calendar parameters/variable available
1061      to all packages
1062    
1063    checkpoint58v_post
1064    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
1065      useDynP_inEos_Zc tested.
1066    o pkg/exf: changes to properly interpolate/mask/scale initial fields
1067    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
1068      and portions thereof.  See read_cs.txt for description and examples.
1069    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
1070      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
1071      following the great-circle arc between those 2 points.
1072    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
1073      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
1074    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
1075     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
1076     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
1077     - still needs work (not working with some options ; efficiency to improve)
1078       and serious testing.
1079     - use this scheme for temperature & salinity in 2 advection test exp.:
1080       advect_xy & advect_xz, respectively.
1081    
1082    checkpoint58u_post
1083    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
1084    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
1085    o testreport: add option "-skipdir" to skip some test.
1086    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
1087      momentum calculation.
1088    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
1089    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
1090      remove checkpoint.F and the_correction_step.F (no longer used);
1091      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
1092    o add option (linFSConserveTr) to correct for tracer source/sink due to
1093      Linear Free surface
1094    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
1095    o pkg/thsice: fix reading mnc-pickups
1096    
1097    checkpoint58t_post
1098    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
1099    o pkg/mdsio:
1100     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
1101       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
1102       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
1103     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1104     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1105       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1106     - new S/R (to replace MDSWRITEMETA), which allows to write more
1107       informations (variable names, time ...) to meta files.
1108     - modify rdmds.m to give back the meta file content.
1109    o pkg/diagnostics: change vertical interpolation to be safer, and more
1110       flexible (define p-levels to interpolate to in data.diagnostics);
1111      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1112       diagnostic pointer.
1113    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1114    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1115    o fix multi-category seaice:
1116     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1117       SEAICE_MULTICATEGORY
1118     - fix short wave heat flux
1119    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1120       and allow to use EVP solver. Change forward lab_sea: test both EVP
1121       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1122    o Initial check-in of lab_sea adjoint
1123      (very similar to natl_box_adjoint/code_seaice)
1124      * used C-grid and EVP solver
1125      * used KPP, GM/Redi
1126      * uses inAdExact=.TRUE.
1127      * gradient checks fail for both ADM and TLM
1128        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1129        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1130        issue is related to forward mismatch between g77 an ifort
1131    o pkg/seaice: overhaul of thermodynamics
1132     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1133     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1134     - move a few global fields out of SEAICE.h into seaice_growth.F and
1135       make them 2D (FICE/QNETO/ ...)
1136     - remove FO (it is the same as QNETO)
1137     - introduce a few local fields to avoid modifying external fields such
1138       as atemp, etc.
1139    
1140    checkpoint58s_post
1141    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1142      changed exf_set_gen.F so that
1143        genperiod=0 means input file is one time-constant field and
1144        genperiod=-12 means input file contains 12 monthly means
1145    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1146      this affects truncation error ; generate new output file for exp. which
1147      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1148        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1149        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1150        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1151        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1152        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1153    o start implementation of deep-atmosphere and anelastic formulation
1154    o verification: remove 2nd copy of input files and use script "prepare_run"
1155      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1156    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1157    o profiles: fix for multithreaded case
1158    
1159    o diagnostics: rename few diags:
1160      s/'PRESSURE'/'RCENTER '/g
1161      s/'TICE    '/'oceFreez'/g
1162      s/'TAUX    '/'oceTAUX '/g
1163      s/'TAUY    '/'oceTAUY '/g
1164      s/'SWFLUX  '/'oceQsw  '/g
1165      s/DIFx/DFxE/g
1166      s/DIFy/DFyE/g
1167      and add few ocean-forcing diagnostics:
1168      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
1169    o modifications to pkg/seaice/growth.F and budget.F, which change results of
1170      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
1171      as actual snow thickness.  It now refers everywhere to effective snow
1172      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
1173    
1174    checkpoint58r_post
1175    o modifications to pkg/seaice/growth.F, which change results of
1176      lab_sea experiment: fixes pertain to melting snow over open water, to
1177      masking EVAP under sea ice, and to using the correct AREA variable for
1178      computations of EVAP, PRECIP, HSNOW, and GHEFF
1179    o add ability to read bathy, salt, and theta using MNC (off by def)
1180    o add flooding algorithm and advection of HSNOW for pkg/seaice;
1181      both are turned off by default and do no change any results
1182    o seaice advection with pkg/thsice: a step toward the use of non-linear
1183      advection scheme, but #ifdef or commented out for now (requires more EXCH).
1184    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
1185      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
1186      in natl_box (affects results @ truncation level: update output.txt)
1187    o multi-threading and IO:
1188      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
1189      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
1190        (needed to work with SingleCpuIO): tested in all verif. exp.
1191    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
1192      affects the results (but none of the verification test uses this scheme).
1193    o Adding some pkg/diagnostics capability to pkg/seaice
1194      (will certainly be subject to changes)
1195    o ctrl: adding new control variables:
1196      lwflux, lwdown, evap, snowprecip, apressure, runoff
1197    
1198    checkpoint58q_post
1199    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
1200      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
1201      high_res_cube configuration by 4% on Columbia.
1202    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
1203      add (in global_with_exf/code) a version of EXF_INTERP_READ without
1204      dynamical allocation (seems to work in multi-threaded).
1205    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
1206      single CPU io) so that TAF does not have to see EESUPPORT.h
1207    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
1208    
1209    checkpoint58p_post
1210    o obcs: stop if obcs is used with useCDscheme = .true.
1211    o shelfice:
1212     - fix a sign error so that no slip at shelfice interface works
1213     - remove stop for combination non-hydrostatic code and shelfice. That does
1214       not mean, that the results are correct, but at least they are numerically
1215       stable
1216    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
1217    o added adjoint exch routined for all exch*3d* routines
1218      and updated flow directives
1219    
1220    checkpoint58o_post
1221    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
1222      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
1223    o change controling S/R for writing pickup file (new S/R do_write_pickup)
1224      and clean-up reading/writing of pickup files.
1225    o fix local version of read/write pickup (NH part) in rotating_tank/code
1226    o simplify EXCH interface:
1227     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1228     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1229    o added the regrid package
1230    o shelfice:
1231     - add a simple boundary layer scheme to reduce noise
1232     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1233    
1234    checkpoint58n_post
1235    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1236       local variable (not in common block).
1237    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1238      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1239      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1240        to work with SingleCpuIO.
1241    o add "_d 0" to real constant of pkg/cfc subroutines ;
1242       update exp. cfc_exemple & tutorial_cfc_offline output files.
1243    o multi-threading and IO:
1244      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1245        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1246      - barrier before and after reading.
1247      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1248      - avoid using MDS_WRITELOCAL for LAND pkg output.
1249      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1250        common-block variables ; Allows multi-threading with master-thread IO.
1251    o change default MAX_NO_THREADS from 32 to 4 ;
1252      and stop cleanly when MAX_NO_THREADS is too small.
1253    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1254    
1255    checkpoint58m_post
1256    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1257       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1258    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1259       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1260       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1261    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1262        add MITgcm_tutorials (= code + all the tutorials)
1263    o ecco, option to compute cost for total ssh (mean+anom)
1264    o consistent with addition of ptracer and ssh in pkg/profiles
1265    o profiles: adding ptracer and ssh
1266    o testreport: change multi-test output-file name
1267      (from output.txt.{name} to output.{name}.txt)
1268    o profiles: now ok for mutli-tiles case
1269    o seaice: add 4 parameters for different advection schemes for area,
1270      (effective) seaice thickness, enthalphy, and snow height. Their default
1271      is the standard parameter SEAICEadvScheme
1272    o calc_gw:
1273     - add cosFacU in zonal viscous flux (harmonic.visc.).
1274     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1275       of tutorial_plume_on_slope.
1276    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1277    o calc_gw: true flux-form, account for horizontal grid spacing.
1278      update rotating_tank results, but not plume_on_slope (affected at
1279      truncation level, 11 digits).
1280    
1281    checkpoint58l_post
1282    o calc_gw:
1283     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1284     - remove side-drag for now (need to fix it); update plume_on_slope results.
1285     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
1286    o commit code to make SST/SSS weights spatially variable
1287      (based on either variable in-situ or variable initial T/S weights)
1288    o pkg/ecco:
1289      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
1290        now based on horizontally varying weights wthetaLev, wsaltLev
1291      * cost_averagesflags now returns year indices in addition to day, month
1292      * sflux balance is performed on annual basis
1293        (sflxumm, sfluxmm2, bal_sfluxmm)
1294      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
1295        including separate counting and multipliers
1296    o pkg/rbcs
1297      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
1298    
1299    checkpoint58k_post
1300    o testreport:
1301     - always build in dir. "build" (if not there, mkdir build instead of building
1302       & running in input)
1303     - run in dir run (if it exists), in build otherwise.
1304     - call prepare_run (if input/prepare_run exists)
1305     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1306    o pkg/exf modifications to interpolation and rotation routines for more
1307       reasonable treatment of North Pole singularity: for tracers North Pole
1308       value is set to northernmost zonal-mean value, for zonal velocity it is
1309       set to zero, and for meridional velocity it is set to northernmost value.
1310    o pkg/exf/exf_check_range.F
1311     - add tile index to diagnostics and move stop statement to the very
1312       end of the routine.
1313    o pkg/diagnostics: (diagnostics_main_init.F)
1314      define title of isomorphic variables according to the current config.
1315    o pkg/thsice with pkg/seaice dynamics:
1316    - fix domain of computation (interior only, required for exf) and do exchanges
1317    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1318    o towards a standard way of dealing with multi-threading in MONITOR
1319      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1320    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1321       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1322    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1323    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1324    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1325       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1326    o tracer advection:
1327     - clean-up and simplify calc_common_factors.F
1328     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1329       advection subroutine (but still not used within DST advection S/R)
1330    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1331    
1332    checkpoint58j_post
1333    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1334      from file (collects calls previously in FORWARD_STEP)
1335    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1336    o adjoint store dir. adjusted accordingly
1337    o genmake2
1338      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1339    
1340    checkpoint58i_post
1341    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1342      on wind stress (SEAICEstressFactor defaults to 1.)
1343    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1344      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1345    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1346      on CS-grid: no longer loosing mass.
1347    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1348    o pkg/ggl90: fix sloppy output and fix a bug
1349    o pkg/seaice: added SEAICEuseEVPpickup parameter
1350      - Set to false in order to start EVP solver with
1351        non-EVP pickup files when using SEAICEuseEVP
1352      - fix sign error in diffusion in seaice_calc_rhs
1353    
1354    checkpoint58h_post
1355    * Modifications for bottom topography control
1356      o replace hFacC by _hFacC at various places
1357      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1358      o add non-self-adjoint cg2d_nsa
1359      o update autodiff support routines
1360      o re-initialise hfac after ctrl_depth_ini
1361      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1362    * Adding verification for 5x5 box (4-layer) bottom topography control
1363    
1364    checkpoint58g_post
1365    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1366       used for mean seasonal cycle, mean diurnal cycle); add an example
1367       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1368    o pkg/ggl90:
1369      - add parameter (minimum surface kinetic energy)
1370      - fix bug (avoiding division by zero)
1371    o couple pkg/thsice to pkg/seaice:
1372      - modify advection in seaice to accomodate new scalar fields to be advected
1373      - only muliDimAdection scheme work with seaice/thsice
1374      - mapping of thsice-variables to seaice-variables, back and forth
1375      - does not break the verification experiments, but does not give the
1376        desired results either
1377    o pkg/seaice
1378      - make (default) second order advection a bit less confusing?
1379    
1380    checkpoint58f_post
1381    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1382      to pkg/seaice):
1383      - new routines thsice_map_exf and thsice_get_exf provide the interface
1384      - add an additional formal parameter to thsice_solve4temp
1385    o pkg/exf:
1386      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1387      - correct Stefan-Boltzmann constant
1388      - new parameter for longwave surface emittance
1389      - separate some stuff from exf_bulkformulae into new routines  
1390        exf_radiation, exf_wind
1391      - add new parameters and constants: longwave emissivity for ocean, ice
1392        and snow, evaporation parameters over ice
1393      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1394        either wind from stress or stress from wind
1395    o pkg/thSIce:
1396    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1397    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1398       and THSICE_CALC_THICKN
1399    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1400    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1401      to make debugging easier.
1402    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1403    o pkg/bulk_force:
1404      - clean-up comments and parameters ;
1405      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1406    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1407      generate new output for test-experiment: aim.5l_cs.thSI
1408    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1409      testreport accordingly
1410    
1411    checkpoint58e_post
1412    o SEAICE_CGRID adjoint done
1413    o R_STAR adjoint implemented.
1414      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1415      * need to sort out init. of h0facc, etc.
1416    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1417      to be able to use it in pure forward.
1418    
1419    checkpoint58d_post
1420    o upgrade simple test-experiment to tutorial example:
1421     step.1: duplicate the experiment and (step.2) will remove the old copy.
1422      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1423      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1424      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1425      tutorial_global_oce_biogeo    <- copy of dic_example
1426      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1427      tutorial_plume_on_slope       <- copy of plume_on_slope
1428      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1429      tutorial_global_oce_optim     <- empty for now (David ?)
1430      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1431     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1432    o correct a sign problem in cost_scat.F
1433    o obcs and ptracers: fix boundary conditions for advections schemes
1434      with larger stencil
1435    o thsice adjoint: start
1436    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1437      completeness
1438    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1439      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1440    o ptracers adjoint:
1441      * avoid extensive recomputatations
1442      * fix missing re-init. of gptr (missed by TAF)
1443    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
1444      me to turn off the excessive output to STDOUT that this package produces
1445    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1446      and add those terms in Vector-Invariant formulation.
1447    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1448      if the control period (xx_hfluxperiod etc) is 0
1449    o in profiles pkg, clean routines and fix details
1450    o in ecco pkg, reading ssh data:
1451      fix problem in case the model does not start at iter0=0
1452    o fix mnc-pickup/restart for ptracers
1453    o new package prifiles:
1454      code to compute profile-based cost by Gael Forget
1455      (modifs in ecco, ctrl, autodiff)
1456    o Benign bug fix in initialization (spotted by M. Mazloff) of
1457      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1458    
1459    checkpoint58c_post
1460    o adjoint: finish NLFS adjoint and provide reference output in
1461      verification/global_ocean.90x40x15/results_ad_nlfs
1462    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1463      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1464      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1465      with SEAICE_CGRID defined.
1466    o move calendarDumps from "data" to "data.cal" and clean-up the code
1467      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1468    o add useEXF & useCAL flags (for now, set in hard-coded way)
1469    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1470      (were missing in NH mode, and wrong in quasihydrostatic mode).
1471      waiting for Chris updated version of calc_gw to add those CALLs.
1472    o fix bug in quasihydrostatic S/R ;
1473      add a test for this option: global_ocean.90x40x15.qshyd
1474    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1475      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1476    o add on/off flag useOffLine for package OFFLINE
1477    o seaice:
1478      - modify advection so that it works also on the C-grid
1479      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1480        problem in multi-tile runs with C-grid
1481      - add flags for clipping ice velocities and/or masking solver forcing
1482      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1483        C-grid solver
1484      - added a few comments to seaice_diffusion.F
1485      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1486        are now exclusive)
1487      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1488        required re-ordering the code a little:
1489       + make DAIRN global variable (defined in SEAICE)
1490       + move computation of the viscosities eta and zeta into a new separate
1491         routine (because I need to recompute them in seaice_ocean_stress.F)
1492    
1493    checkpoint58b_post
1494    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1495      update output.txt of exp. aim.5l_cs.thSI
1496    o various mnc cleanups and improvements:
1497      + shrink lookup tables by factor of ~4
1498      + better error reporting when running out of lookup space
1499      + able to handle longer path/file names (up to 500 chars)
1500    o adjoint:
1501      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1502      - TBD: "hidden" mom_vecinv recomp. in dynamics
1503    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1504     (allow to differentiate between forcing components using new integer flags:
1505      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1506     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1507    o ecco
1508      - enable trend removal from SSH anomaly obs.
1509    o adjoint
1510      - a fix for PmEpR when #undef EXACT_CONSERV
1511      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1512      - try to fix "hidden" recomp. in forward_step for NLFS
1513        (NLFS seems broken sometimes after I checked it in)
1514    o seaice:
1515     - add c-grid version of the dynamic solver:
1516       + three new routines that are the c-grid substitute lsr, dynsolver
1517         and ostres
1518       + put a few fields that were local to dynsolver into global common
1519         blocks, so that I can move the computation of stresses etc into
1520         seaice_lsr (saves coding but may break the adjoint).
1521     - replace more hardwired parameters by runtime parameters
1522     - add ice masks that mask the rhs of the implicit solvers where there
1523       is no ice (commented out in seaice_dynsolver, because i am not sure
1524       if this works properly), eventually this should replace the clipping
1525       of ice velocities in seaice_dynsolver to +/-40cm/s.
1526    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1527      include it only where its needed
1528    o move balancing of fluxes before the call of external_forcing_surf
1529    o seaice:
1530      - correct units of turning angles (now they are really in degrees)
1531      - move computation of GWATX/Y out of main routine into dynsolver
1532      - initialize GWATX/Y in seaice_init
1533    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1534      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1535    o seaice: add runtime flags for turning angles (default to zero)
1536    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1537      and trend from exf forcing and ctrl control adjustments
1538    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1539      (since checkpoint57x_post)
1540    o change the default rotation period to 86164.s = the Earth rotation
1541    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1542      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1543    o seaice advection: add code for choosing between the default (2nd order
1544      central differences) and multiDim advection schemes provided by
1545      pkg/generic_advdiff
1546    o seaice:
1547      - removed all references to SEAICE_GRID.h fields from
1548        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1549        (cubed-sphere configuration will change a little)
1550      - grid computations in seaice_init are obsolete now.
1551      - cleaned up code a little so that is easier to read (hopefully).
1552      - added new (better?) discretizations of default advection and diffusion
1553        (turn on with SEAICEuseFluxForm)
1554      - replace 1 in 3d global fields by kSurface in growth.F
1555      
1556    checkpoint58a_post
1557    o seaice:
1558      - bug fix in advect.F
1559    o shelfice:
1560      - separate shelfice load anomaly from pload (breaks with time
1561        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1562        Its default is 0., but it may be computed more cleverly from (unknown)
1563        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1564        done offline. A good approximation of the pressure load anomaly is
1565        necessary to avoid large initial adjustment processes underneath
1566        deep-reaching shelfice.
1567      - small fix in ISOMIP shelfice_thermodynamics
1568      - add more sophisticated thermodynamics of Hellmer (1989), this is
1569        now the default
1570      - give a few constants more intuitive names
1571    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1572      if bulk formulae are used in long integration (especially EmPmR). Turn
1573      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1574      if balancePrintMean, the imbalance that is substracted is printed to
1575      STDOUT.
1576    o fix bug (typo) in obcs_apply_eta.F
1577    o add a new package shelfice which enables us to model the circulation
1578      underneath shelf-ice with draughts of hundreds of meters.
1579     - works
1580     - to do: + include improved thermodynamics
1581              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1582                instead of new field kTopC
1583              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1584                instead of new field R_shelfIce and new code in ini_depth.F
1585                and ini_mask_etc.F?
1586              + adjust vertical mixing schemes?
1587    o seaice pkg:
1588     - add a cpp-flag to include a simple formula for a salinity dependent
1589       freezing point of sea water at the surface
1590     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1591       meridional stresses are now different (and hopefully correct)
1592    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1593       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1594       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1595    o pkg/diagnostics: add options and parameters for regional-statistics
1596       diagnostics ; define regions by reading a region-mask from a file
1597       (might add other options later)
1598    o pkg/bulk_force:
1599     - add option and parameters to use AIM surface-flux formulae.
1600     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1601       others forcing fields (defined in PARM05, parameter file "data") are loaded
1602       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1603     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1604     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1605     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1606       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1607     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1608    
1609    checkpoint58
1610    o add "--embed-source" option to genmake2 which, when the supporting
1611      tools can be compiled (as determined by genmake2) will turn on the
1612      embed_files package which then embeds the entire MITgcm source code
1613      (*.[fFhc] + Makefile) used for the build within the executable
1614      - requested by CNH but off by default
1615      - adds a paltry <9MB to the mitgcmuv executable in most cases
1616      - only writes the output when useEMBEDSRC in eedata is true
1617    o clean up 3-dim. relaxation codes:
1618      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1619      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1620      * Thanks to Tom Haine for testing!
1621    
1622    checkpoint57z_post
1623    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1624      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1625    o fix the pickup behavior for obcs in combination with ptracers
1626    o fix a bug in ptracers_external_fields_load
1627    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1628      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1629    o transfered surface NH pressure to eta field (if exactConserv).
1630    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1631         and update lab_sea output.txt file.
1632    o completing 3-dim. relaxation code: additional term
1633         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1634      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1635      * At compile time, in "EXF_OPTIONS.h" set
1636          #define  ALLOW_CLIMTEMP_RELAXATION
1637          #define  ALLOW_CLIMSALT_RELAXATION
1638      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1639          tauThetaClimRelax3Dim = 15552000.0,
1640          tauSaltClimRelax3Dim  = 15552000.0,
1641      * 3 cases:
1642          1) Use a constant-in-time 3-dim. field
1643          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1644          3) Real-time relax. to time-evolving prescribed field
1645    o Adding Laplacian-type smoothness constraint on
1646      initial and boundary (forcing) controls (ic, bc)
1647      * enable at compile-time via
1648        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1649      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1650      * Absolute scale somewhat unclear so far
1651      * no area weighting was included since no other cost term does so far
1652    
1653    checkpoint57y_post
1654    First step for a NLFS adjoint
1655    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1656    o new init. routines for calc_r_star, calc_surf_dr
1657    o still need to deal with ini_masks_etc
1658    o testreport seemed happy
1659    checkpoint57y_pre
1660    
1661    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1662    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1663    o add new offset feature to offline pkg (plus minor cleanup)
1664    o cfc fixes for final year of integration
1665    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1666      be in GCHEM_OPTIONS).
1667    
1668    checkpoint57x_post
1669    o fix testreport Pb in multiple test experiment.
1670    o cleanup our namelist syntax in verification:
1671      - make it more F95 standards compliant (some work still needed)
1672      - allows the vast majority of our tests to work with gfortran
1673    o Non-Hydrostatic:
1674     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1675     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1676    o Allow to apply AB on T,S rather than on AB(gT,gS):
1677     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1678     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1679       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1680     - need a "clever" read_pickup to restart from the other AB formulation
1681    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1682    o remove some unused variables (reduces number of compiler warnings)
1683    o adjoint
1684      * Disable useVariableViscosity for adjoint for time being
1685        (there are a number of extensive recomputations)
1686      * Initialize certain variables needed for adjoint
1687    
1688    checkpoint57w_post
1689    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1690                 fix the singleCpuIO RS version of MDSWRITEFIELD
1691       and add a WARNING if using globalFiles=T with multi-processors.
1692    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1693      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1694    o tracer advection scheme:
1695      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1696       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1697       was not very convenient).
1698      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1699       (further tests needed for the implicit DST & Flux-Limiter schemes).
1700    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1701      and sRef for convenience, handy, when you want to initialize
1702      ptracers in a large domain with a constant non-zero value. Also,
1703      untangle ptracers_init.F a little.
1704    
1705    checkpoint57v_post
1706    o change dome exp. to use variable viscosity in side-drag terms.
1707    o remove all the files from the cfc_offline test since they are now
1708      incorporated into tutorial_cfc_offline which has been producing
1709      identical results for a few days of testing
1710    o add new parameter: sideDragFactor to enable half-slip-side BC
1711      and change side-drag S/R to use viscosity from mom_calc_visc
1712      (can switch back by setting sideDragFactor=0.); affects results at
1713      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1714       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1715    o vorticity & strain are now computed without masking, to account for
1716      no-slip-side BC in variable viscosity calculation ; mask is applied
1717      anyway later on, before computing advection/coriolis terms.
1718    o modify exp4 to test new obcs support for reading from external files
1719      and for passive tracers
1720    o fix behavior of ptracers_monitor when monitor output is written to a
1721      netcdf-file; still not independent of monitor.F (writes in the same
1722      file).
1723    o change default value of tRef (put a uniform, meaningful value for ocean
1724      & atmos) and initialize sRef (was missing, as Martin mentioned).
1725    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1726      to be proportional to enstrophy dissipation length.  Thus,
1727       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1728      This is now consistent with Smagorinsky and with the manual.
1729    
1730    checkpoint57u_post
1731    o OBCS and PTRACERS: add open boundary support for passive tracers
1732      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1733        OB-values from file; this is not different from the way theta and salinity
1734        are treated
1735      - however, Orlanski-radiation conditions are not supported, and the model
1736        will stop if you use pTracers and Orlanski at the same time.
1737      - beefed up the rountine obcs_external_fields_load: now only those open
1738        boundary values are overwritten with values from files for which there
1739        are really files, otherwise the OB-fields remain untouched. This makes
1740        it possible to use different OBs at different ends of the domain (as
1741        with EXF)
1742    o reduce number of exch calls in shap_filt (s2).
1743    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1744      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1745    
1746    checkpoint57t_post
1747    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1748    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1749      same truncation, independent of the face number: affects affects several
1750      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1751    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1752      note that biharmonic viscosity + no-slip was not tested in any experiment.
1753    o fix bug in non-linear free-surf side-drag ; generate new output for
1754      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1755    o make mnc honor the writeBinaryPrec flag for most kinds of output
1756    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1757    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1758      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1759    o add brackets in multi-terms sum to get same truncation, independent of
1760      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1761      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1762    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1763      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1764      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1765      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1766      Suggested values of viscosity parameters found in mom_calc_visc.
1767      Many new viscosity diagnostics available.
1768    
1769    checkpoint57s_post
1770    o Add clearing-house for viscosity calculations, mom_calc_visc and
1771      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1772      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1773      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1774      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1775      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1776      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1777      ViscAhStrain and viscAhTension are now retired.
1778    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1779    o In response to JMC's bug report, genmake2 now ignores any soft-links
1780      that it finds in the *current* directory when searching for files.
1781      Soft-links found in any other source directories will still work as
1782      they did before.
1783    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1784      a C routine to unlimit the stack size
1785    o mnc-ify pkg/aim snapshot vars
1786    o mnc-ify pkg/land as requested by Daniel
1787    o various changes to mnc including:
1788      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1789      - output can now be grouped so that all files within a group
1790          change the ITER portion of their names in lock-step together
1791      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1792          and works with both EXCH1 and EXCH2 (but needs more testing)
1793      - writing works for all verification test cases w/ g77 on Linux
1794    
1795    checkpoint57r_post
1796    o make MNC variable initialization happen earlier
1797    o add diagnostics for (almost) each term of the momentum Eq.
1798    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1799    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1800    o remove MINIMAL_TAVE_OUTPUT option ;
1801      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1802    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1803      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1804    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1805    o add time-dependent SST, SSS control
1806    o cost terms in ecco/ modularized (new cost_generic.F)
1807    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1808    o new infrastructure for seaice model vs. obs misfits in seaice/
1809      * driver from the_main_loop.F is seaice_cost_driver.F
1810      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1811      * gradient check in Exp. 6a of natl_box_adjoint/
1812    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1813      (see README file)
1814    
1815    checkpoint57q_post
1816    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1817    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1818      - bug was reported by Jean-Michel and Ian Fenty
1819    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1820      update exp. cpl_aim+ocn output.
1821    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1822      Needed for high-res. runs with large global files
1823      to be able to limit tapelev size
1824    o Changed some tests for adjoint:
1825      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1826      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1827      * global_ocean.90x40x15/ back to default 3-level checkpointing
1828    o Modifications to enable scripted COMMON to MODULE conversion
1829      * verification/OpenAD/code/ has necessary scripts and description;
1830      * converts, compiles and runs successfully;
1831    
1832    checkpoint57p_post
1833    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1834    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1835      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1836    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1837    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1838      (was already the case for dissipation with mom_vecinv,
1839       and also the case for grad.PhiHyd when staggered-timeStep)
1840      This will allow to put dissipation out-off the AB time-stepping.
1841     Unfortunately, affects truncation error. Update output of exp. that "fails"
1842      (cg2d matching number) and leave the others for later: front_relax(10),
1843      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1844      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1845    
1846    checkpoint57o_post
1847    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1848      (2) its ready to be documented during the 20050801 DocFest
1849    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1850      for ideal_2D_oce and lab_sea on linux_ia32_g77
1851    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1852      in global1x1_tot/code_seaice_adj to access indices 32, 33
1853      (worth another tag)
1854    
1855    checkpoint57n_post
1856    o adding precip control xx_precip 32
1857    o adding swflux control xx_swflux 33
1858    o Replacing 10 forcing penalty cost routines by 1 generic.
1859    o Implementing partitioning in time-mean and variable adjustment
1860      for atmos. state.
1861    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1862    o in natl_box_adjoint:
1863      * updated exp 1 to 10
1864        (but does not have time-mean vs. variable split results yet)
1865    o updated global1x1/*_seaice_adj/
1866      to incorporate latest changes
1867    o enable useSingleCpuIO for mdsio vector routines
1868      (applies in particular to tapelev I/O)

1870    
1871    checkpoint57m_post
1872    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
1873      and advect_cs (use EXCH-2 and standard cs-32 grid files).
1874    o pkg/exch2: filling of face-corner halo regions is optional
1875      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
1876    
1877    checkpoint57l_post
1878     tag before updating tutorials (pre-release-2)
1879    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
1880       for output and interpolation of input fields onto model grid)
1881    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
1882       Affects results of exp. rotating_tank ; update output.txt.
1883    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
1884          and taking the square quantity and/or using a fraction-weight field.
1885    o fix aim_diagnostics_init.F mate numbers.
1886    o add mnc output capability to diagnostics/diagstat and update
1887      our cvsignore files for the ACSII output generated
1888    
1889    checkpoint57k_post

1891      new EXF diagnostics output.
1892    
1893    checkpoint57j_post
1894    o exf
1895      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1896        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1897        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1898      * extended diagnostics output
1899        - now includes all EXF variables
1900        - hs, hl moved to common block
1901        - separate S/R for diagnostics, called after ctrl vector is added
1902        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1903        - EXFqnet contains true Qnet (i.e. includes qsw)
1904      * updated verif. lab_sea, global_with_exf
1905      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1906        to ensure that diagnostics sees a true EXFqnet
1907    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1908    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1909      several times with different frequencies.
1910    o mnc-ify the thsice package as requested by Daniel Enderton
1911      - the monitor--MNC output needs work
1912      - many attributes need to be added (most are currently blank)
1913    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1914      - many attributes need to be added (most are currently blank)
1915    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)

1922    
1923    checkpoint57i_post
1924    o Diagnostics package was changed: diagnostic allocation is now deactivated
1925      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1926    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1927      add 1rst Order upwind vertical Shear.
1928    o add a quick fix for A/B checkpointing in OFFLINE mode
1929    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1930      end-run around the C/Fortran linking horror in eesup/src/timers.F
1931    o added pkg/runclock: allows user to terminate run based on wall clock
1932    o added non-hydrostatic scaling parameter: nh_am2
1933    o pkg/my82: futile attempt to make results compiler-independent by adding
1934      some "_d 0", etc. no effect.
1935    o for mnc output, fill the 'T' coordinate var with myTime and create a
1936      separate 'iter' variable for iteration count
1937    o pkg/diagnostics:
1938      add new capability: output of Global/Regional & per-level statistics ;
1939      tested against monitor output (including land & thSIce) on various exp.
1940    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1941    
1942    checkpoint57h_done
1943      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1944      data.diagnostics, data.gchem, data.ptracers) is done.
1945    
1946    o pkg/diagnostics: prepare for Global/Regional statistics.
1947      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1948    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1949      and rename it: DIFFERENT_MULTIPLE
1950    
1951    checkpoint57h_post
1952    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1953    o pkg/diagnostics: change output frequency, now in seconds (instead
1954      of Nb of iterations). This requires to change data.diagnostics.
1955    checkpoint57h_pre
1956    
1957    o in mnc, let the user create the output dir if both mnc_outdir_date
1958      and mnc_outdir_num are false
1959    o add fflags() to pkg/diagnostics which allows one to specify, on a
1960      per-file basis, the file precision [default behavior is unchanged]
1961    o added diagnostics to pkg/kpp, including computation of mixed layer
1962      depth based on a temperature/density criterion
1963    o updated verification/natl_box to test the new pkg/kpp diagnostics
1964    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1965    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1966    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1967      not mnc -- this mistake was found by JMC and is now corrected
1968    
1969    checkpoint57g_post
1970    o add Adams-Bashforth 3rd Order time stepping:
1971      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1972      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1973    checkpoint57g_pre
1974    
1975    o make lambda[Theta,Salt]ClimRelax spatially varying
1976      (default remains spatially uniform constant based on tau)
1977    o added new control variables
1978      * init. uVel, vVel, etanN
1979      * lambda[Theta,Salt]ClimRelax
1980    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1981      (suggested by G. Forget)
1982    
1983    checkpoint57f_post
1984    o add parameter "baseTime" = model base time = time at iteration zero
1985      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1986      account for baseTime shift
1987    o move Coriolis arrays from PARAMS.h to GRID.h
1988    checkpoint57f_pre
1989    
1990    o mnc-ifying the seaice package
1991    o introduced an alternative length scale calculation for use in the limiting
1992      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1993    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1994    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1995      as well as grad(vort3).  Made it compatible with both approximate form
1996      for the cubed sphere and full form of these gradients.  Added flag
1997      useFullLeith to select between approximate and full form.  
1998    o add "d0" in getcon.F to reduce differences between compilers/platforms

2000    o change port_rand funtion to allow to set the seed.
2001    o fix obscure MNC bug involving conversion between reals and integers
2002      - it caused no problems with certain (eg. gcc, ifc) compilers but the
2003        new version is now more standards-compliant
2004    o adjoint-related modifications
2005      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint

2014      update output.txt of exp. fizhi-gridalt-hs
2015    o add more "Z" dimensions and associated coordinate vars to MNC
2016    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
2017    o parameter calendarDumps: when set, approximate months (30-31 days) and years
2018      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
2019      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
2020      months and years.  Requires pkg/cal.
2021    o diagnostics: add pickup functionality
2022      - off by default for backwards compatibility
2023      - current version only uses MDSIO -- MNC will be added
2024    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
2025    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
2026    
2027    checkpoint57d_post
2028    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
2029    o modify verification/ideal_2D_oce so that it tests the creation of mnc
2030      output from the diagnostics package
2031    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
2032    o make genmake2 more portable by using ".$FS" instead of ".f" for more
2033      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
2034    o add coordinate variables to the MNC output from the diagnostics package
2035    o change MNC-flags default value: true when useMNC=TRUE
2036    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
2037      the ability (off by default) to read the grid information using MNC
2038    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
2039    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
2040    o do snap-shot diagnostics at the middle of the time-interval (instead of
2041      at the end).
2042    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
2043      new test for AIM with thSIce + slab-ocean
2044    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
2045    o move state variable diagnostics to the beginning of the time step ;
2046      (note: still needs some work specially for snap-shot diagnostics)
2047      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
2048    
2049    checkpoint57c_post
2050    o Change testing option (-ieee) to get closer agreement between g77 & ifort
2051    o generate new output.txt files on faulks with g77 & the new -ieee option
2052    checkpoint57c_pre
2053    
2054    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
2055      update output.txt of exp. global_ocean.90x40x15
2056    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
2057      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
2058    o add saltFlux(+File) forcing capability with periodicExternalForcing
2059    o allow to use pkg diagnostics for GM-Redi & ThSIce output
2060    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
2061    o improvements for the MNC output from DIAGNOSTICS:
2062      - correct handling of the unlimitied dimension
2063      - all dims now have associated coordinate variables
2064      - variables located at U, V, and Corner ("Z") points are now written
2065        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
2066        *all* data points are output
2067    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
2068    o added pkg/seaice/seaice_monitor.F
2069    o mdsio_readfield.F can now read files visible only to master MPI process.
2070    o pkg/seaice: some test code for ice-modified ocean stress
2071    o exf_getffields interpolation defaults to bilinear for all scalar forcing
2072      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
2073      spurious negative numbers for precipitation and humidity.  Will cause
2074      some small numerical differences for integrations using pkg/exf/exf_interp.F.
2075    o pkg/ctrl/
2076      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
2077        May be enabled via doPackDiag
2078      *  introduce z-scaling of
2079         + gradient (doZscalePack) and
2080         + control (doZscaleUnpack)
2081    o pkg/mdsio/
2082      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
2083      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
2084    
2085    checkpoint57b_post
2086    o simplify options in diagnostics_fill arguments (remove weird combinations)
2087    o fix MNC coordinate variables so that they now contain per-face index
2088      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
2089      general, EXCH2 grids are only aligned to a "local" coordinate system
2090    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
2091    o Implement instantaneous output within pkg diagnostics:
2092      setting a negative frequency in data.diagnostics produces
2093     "snap-shot" output (as opposed to time-average if freq > 0)
2094    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
2095      NOTE: change ptracer diagnostics name: use 2 characters to work with
2096            more than 9 tracers. Add also diagnostics of advect & diffus flux.
2097    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
2098      becomes the coordinate variable for the 'T' dimension
2099    o add CF-style coordinate variables to MNC
2100      - just a first cut:  numbers are meaningless on the cubesphere and
2101        missing along the T axis but otherwise it works!
2102    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
2103    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
2104    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
2105      this is based directly on what the model compute, so that the content of
2106      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
2107    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
2108    o clean up build options files for SunOS, in particular
2109      - remove -traditional from xmakedepend
2110      - change -xarch=v9 to -xarch=native for f77
2111      - restore use of make (not gmake)
2112      - add CC=gcc if using g77
2113    o changes per discussion of AM, JMC, & EH3 today:
2114      - move redundant "grid" variables out of "state" -- in preparation of
2115        creating proper CF-style coordinate variables and in recognition
2116        that any/all grid variables can be easily copied (eg. w/NCO) from
2117        the grid files into any of the other NetCDF files
2118      - *always* output grid variables with MDSIO (this will eventually be
2119        changed)
2120      - output MNC grid file if useMNC is true
2121    o every instance of _END_MASTER() has been found and replaced with
2122      _END_MASTER( myThid ) in order to satisfy certain picky Sun
2123      preprocessors
2124    o re-arrange diagnostics pkg initialisation:
2125     - allow each package to extend the available diagnostics list
2126     - add some checking and fix small problems (multi-threaded, ...)
2127     - new S/R diagnostics_fill (replace fill_diagnostics):
2128       look through the short list of active diag. (instead of the long list)
2129       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
2130    
2131    checkpoint57a_post
2132    o this set of changes restores TAMC compatibility
2133      tested for global_ocean.90x40x15 adjoint on trough
2134      (what a pain)
2135    
2136    checkpoint57a_pre
2137    o some modifs in tools/build_options for sunos
2138    o call ctrl_pack for ctrl at end for optimcycle=0
2139    
2140    checkpoint57
2141    o add horizontal bi-harmonic viscosity for vertical velocity
2142      - new parameter viscA4W (defaults to viscA4)
2143      - affects only non-hydrostatic code
2144      - to be done: no-slip lateral boundary conditions
2145    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
2146    o implement Implicit Vertical advection for pTracers
2147    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
2148      (implemented also for implicit vertical diffusion & advection)
2149    o OBCS: extend application of tracer open boundary conditions
2150      to a strip beyond the boundary of width Olx/Oly
2151    o add call monitor to TAF set of required calls (flow directives)
2152      and include in natl_box_adjoint
2153    o untangle a few ifdefs related to cost, ctrl, autodiff
2154      untangel a few ALLOW_ECCO_OPTIMIZATION
2155    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
2156      (theta2, salt2 in ecco_cost_weights)
2157    
2158    checkpoint56c_post
2159    o OBCS as control variables
2160      - update ctrl_ad_diff.list, obcs_ad_diff.list
2161      - remove balance of obcs controls from default
2162      - fix index bug nobcs in ctrl_init
2163      - fix dummy fields filen in ctrl_pack
2164      - add dummy weights for obcs
2165    o lsopt: comment out fort.94 output
2166    o optim:
2167      - remove unnecessary header files
2168      - adjusted namelists
2169      - add xerbla.F to Makefile
2170    o exf:
2171      - multiple modifications of exf_check_range
2172      - unit change in exf_init_runoff from [m/year] to [m/s]
2173    o mdsio:
2174      - i/o-vector change debugLevel from debLevA to debLevB
2175    
2176    checkpoint56b_post
2177    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
2178      is called from DO_THE_MODEL_IO
2179      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
2180      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
2181      - clean up PTRACERS_WRITE_TIMEAVE a little
2182    o add another verification experiment that tests both the cfc-pkg and
2183      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
2184      reactive tendencies treated inline with regular timestepping
2185    o testreport previously did a lousy job of comparing small numbers, so
2186      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
2187      implemented in the little c-progam tmp_cmpnum.c which is embedded in
2188      testreport.
2189    o ptracers_monitor: bug fix for MPI
2190    
2191    checkpoint56a_post
2192    o GCHEM: finish reorganizating the package
2193      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
2194        (introduces another 3D-array for each passive tracer, but only if
2195        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
2196        gchemTendency is not needed because the timestep is done separately)
2197      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
2198      - GCHEM is now---more or less cleanly---separate from PTRACERS
2199      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
2200        so clear to me how that should be done in a general way.
2201    o CFC: improve formatting of output in CFC_ATMOS
2202    o PTRACERS:
2203      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
2204        that ALL experiments with ptracers enable can be checked. This makes
2205        GCHEM_MONITOR obsolete.
2206      - include a runtime parameter PTRACERS_monitorFreq that defaults to
2207        monitorFreq
2208      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
2209    o add PTRACERS (PTR0[1-5]) to testreport output
2210    o exf_check_range:
2211      * default changed to .TRUE.
2212      * will check values for niter0 if debLevA, every timestep if debLevB
2213      * STOP in exf_check_range if 'out of range'
2214      * range chosen generous to allow for potential extema
2215      TBD: a version with stricter range
2216           permitted range would be runtime parameters
