5      ==============================      ==============================
6    
7    o pkg/mdsio & rw:
8     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
9     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
10    o pkg/flt:
11     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
12       init_fixed & ini_varia.
13     - clean-up & simplify linear interpolation S/R:
14       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
15     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
16     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
17     - add vert. coordinate & horiz. indices to output files.
18     - change vertical position in initial condition, from index to depth [m].
19    o pkg/ggl90: a few modifications:
20     - fix bottom boundary condition, and interpolation of KappaE
21       near top and bottom
22     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
23     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
24     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
25    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
26      (maintain temporary backward compatibility, until next checkpoint)
27    
28    checkpoint61h
29    o pkg/diagnostics with "periodic averaging diagnostics":
30      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
31    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
32    o pkg/obcs: fix loop ranges for balancing code
33    o pkg/flt:
34     - improve criteria for finding which tile owns a float.
35     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
36    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
37      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
38      with ocean biogeo)
39    o pkg/flt:
40     - do some cleaning and fix the restart ;
41     - add output.txt in flt_example/results to get this pkg tested.
42    o genmake2: add an EXTENDED_SRC option and flag.
43       for now, cannot be turned on on command line (only through genmake_local)
44    o pkg/mdsio: read/write vector:
45     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
46     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
47       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
48     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
49      (drop to 4 digits matching for grad). But this test does not look very
50      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
51    
52    checkpoint61g
53    o pkg/flt:
54      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
55       + make OPTIONS file more standard.
56      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
57      - fix _BYTESWAPIO CPP-Flag
58      - standard reading of file-parameter "data.flt"
59      - fix argument list of S/R FLT_RESTART
60      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
61    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
62    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
63      a still unfixed compiler/optimization bug
64    
65    checkpoint61f
66    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
67      update results of global_ocean.cs32x15.icedyn test.
68    o move getcon.F from model/src to pkg/fizhi.
69    o pkg/exf: add parameter for extrapolation of temp up to the surface
70       and option to prevent negative evap (in bulk_largeyeager04 only).
71    o Prather Advection scheme: fix tracer conservation for divergent flow
72      (e.g., when using NonLin Free-Surface).
73    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
74    o gmredi (Visbeck-variable-K):
75     - add more parameters to Visbeck-variable-K.
76     - use a 5 points average for dSigmaR in Visbeck-K calculation
77       (more "homogenous": same stencil and same weights as in dSigmaH)
78     - update output of ideal_2D_oce experiment.
79    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
80      (#undef REAL4_IS_SLOW)
81     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
82       coordinate variable
83     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
84       (surface forcing fields), removes some of the functionality
85     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
86     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
87       probably not all: copy _RS surface flux fields to RL field before
88       calling DIAGNOSTICS_FILL
89     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
90       real*4 (CALL EXCH_*_RS) versions.
91     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
92       (generate new output).
93    
94    checkpoint61e
95    o gmredi (Visbeck-variable-K):
96      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
97      - change computation of Visbeck-K where Slope > Smax :        
98        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
99        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
100    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
101      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
102    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
103    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
104      does not become too large (to avoid precision problems in implicit-diffusion
105      solver); update ideal_2D_oce output.
106    o pkg ggl90:
107      - in ggl90_cal.F: compute only one set of visc/diff, used to
108        step forward TKE/T/S/momentum
109      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
110        have Prandlt =1)
111    o gmredi (fm07):
112      - add lower limit on Transition layer thickness + lower limit on 1/lambda
113      - allow to set few more params from data.gmredi
114    o pkg ggl90:
115          - add missing sqrt(2) factor in computation of mixing length
116            scale in ggl90_calc.F
117            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
118    
119    checkpoint61d
120    o adjoint modifs
121      - adapt to new field rhoInSitu
122      - allow to revert from StoreDynVars2D, StoreDynVars3D
123        to individual fields
124        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
125    o store 3-D (in-situ) density in commom block (DYNVARS.h)
126     - save 1 rho computation.
127     - no longer modify T & S inland when using down_slope pkg.
128    o gad_som : allow to switch to SOM advection for T & S without corresponding
129      pickup files (using new S/R: MDS_CHECK4FILE).
130    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
131      (for useSingleCpuIO to work in multi-threaded)
132    o pkg/shelfice:
133     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
134       with SHELFICEtopoFile in data.shelfice
135     - move code for reading ice shelf topography and modifying hFacC into separate
136       subroutines of the shelfice package
137     - separate initialisation of "fixed" and "variable" variables
138     - kTopC is not (yet) replaced by kSurfC, although this is possible
139    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
140    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
141      and rename:
142      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
143      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
144    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
145    
146    checkpoint61c
147    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
148      to add mass source/sink of fluid in the interior (3-D generalisation
149      of oceanic real-fresh water flux).
150    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
151    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
152    o new pkg: down_slope
153      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
154      - presently, modify T & S inland (dwnslp_calc_rho.F).
155        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
156      - implementation for ocean in P-coords not tested.
157      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
158    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
159      (to facilitate conversion of oceanic pkg to p-coordinate).
160    o change FIND_RHO to FIND_RHO_2D :
161      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
162    o new pkg: cheapaml
163    
164    checkpoint61b
165    o exch2:
166      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
167      - no longer depend on the order sequence (N,S,E,W).
168      - 3rd exchange no longer needed (tested with 24 tiles).
169      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
170      - exch_UV_A-grid readily available (but not yet tested).
171      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
172      (both are no longer needed) in exch_uv: no effect in forward run; but
173       get truncation error differences with adjoint exch.
174    o exch2:
175     - change index-bounds storage (moved from target to local tile,
176       more intuitive this way) ; rename/remove some variables.
177     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
178    
179    checkpoint61a
180    o exch2/matlab-topology-generator:
181      fix bug in index bounds for N-S internal exchange (hard to tell if this
182      had any effect on the solution).
183    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
184      is exceeded
185    o testreport: modify syntax of awk, so that it works also with
186      awk, and not only with nawk and gawk
187    
188    checkpoint61
189    o autodiff
190      Change default for TAF usage by removing argument '-nonew_arg'
191      This changes TAF subroutine argument list (ordering of active var.)
192      Omission of this flag leads to incompatibility w.r.t. TAMC
193      To restore TAMC-compatibility, need following modifs:
194      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
195      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
196      Tested TAF version is 1.9.22
197      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
198    
199    checkpoint60
200    --->>> This is the last checkpoint for which generating the adjoint
201    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
202    --->>> by default.
203    --->>> Future checkpoints will ommit this flag by default.
204    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
205    o pkg/grdchk: Add gradient check to etan0 perturbations.
206    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
207    o pkg/autodiff: more flexibility in zeroadj.
208      model/src: modifying do_oceanic_phys.F accordingly.
209    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
210    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
211      special setup of gmredi for which the adjoint is stable
212      enough for parameter optimization.
213    o bridging the gap between eddy stress and GM.
214      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
215          along with a change in CPP option (now ALLOW_EDDYPSI).
216      -> when using GM w/ GM_AdvForm:
217          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
218          is applied either in the tracer Eq. or in momentum Eq.
219          depending on data.gmredi (intro. GM_InMomAsStress).
220      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
221      The key modifications are in model/src/taueddy_external_forcing.F
222      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
223    
224    checkpoint59r
225    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
226      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
227      fix option to read coriolis(@ cell-corner) from files with CS-grid.
228    o pkg/mnc: add some attributes to standard 1D-coordinate variables
229    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
230      mass points, when using mnc for output
231      - add runtime parameter (missing_value, missing_value_int) to override
232        default (which is the value of getcon('UNDEF'))
233    o pkg/mnc: prepare mnc for the actual use of missing values with the
234      diagnostics package: small fix in mnc_cw_readwrite.template and more
235      initialisation of never used fields
236      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
237      versions
238    o pkg/thsice/thsice_ini_vars.F added default initial values so that
239      thermodynamics sea ice solver does not blow up when some initial fields
240      are missing.
241    o move from external_forcing_surf.F to ini_forcing.F
242      the p-coord. hack consisting in using pLoad to set phi0surf ;
243      update output of tutorial_global_oce_in_p (affected @ truncation level).
244    o Freshen up a bit hs94.1x64x5, notably:
245      remove rotationPeriod and tRef=5*0. (adjoint only), and add
246      exactConserv=.TRUE.
247    o pkg/generic_advdiff:
248      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
249      applies to files where Temperature & Salinity 2nd Order moments are used.
250    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
251      this uses a dynamically allocated internal state data structure
252      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
253      and requires a fortran 90 compiler
254    
255    checkpoint59q
256    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
257       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
258    o Refresh tutorial_global_oce_biogeo, notably:
259      - change bathymetry (put back seamounts in ACC, use hFacs)
260      - change EOS (POLY3 --> JMD95Z)
261      - use Bryan-Lewis vertical diffusivity
262      - use multidimensional advection
263      - remove old virtual virtual in dic pkg, now done through ptracer pkg
264      - change a couple of parameters in dic pkg
265    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
266    o pkg/obcs: change default to OBCSfixTopo = .true.,
267      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
268      - replace "debugMode" with "debugLevel .GE. debLevB"
269    o implementation of TAF directives for gchem,cfc,dic
270    o remove "exp5" (replaced by tutorial_deep_convection).
271    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
272      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
273      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
274      --> changes results in exp4, seaice_obcs
275    o tutorial_deep_convection :
276      update the set-up and increase resolution and domain size ; start
277      from pseudo initial conditions = output at t=120mn in order to see
278      something happening when running testreport.
279    o pkg/seaice: add os7mp as an advection scheme
280                  add check for advection schemes
281                  add a flag for restoring T and S underneath sea ice
282    o pkg/my82: add netcdf-support and diagnostics
283    o thsice pkg:
284      - Now hsMax limits snow height by turning it into ice following
285        flooding scheme (and now conserving energy)
286      - Slight rewriting of the formula in thsice_calc_thick.F
287      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
288      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
289    
290    checkpoint59p
291    o gchem / dic / cfc :
292      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
293      - add new parameter files: "data.dic" & "data.cfc" ;
294      - various re-arrangement in initialisation & header file ;
295      - fix tutorial_global_oce_biogeo for multi-threaded test.
296    o pkg/dic: test for "pickup_dic" file when restarting ;
297      if no pickup-file, can restart with a re-initialised pH (same as it did
298      before) providing pickupStrictlyMatch is set to False.
299    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
300      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
301    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
302      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
303    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
304     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
305       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
306    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
307       scheme to use for vorticty-term ;
308     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
309       (with default selectVortScheme, return to original discretisation)
310     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
311    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
312    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
313      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
314      also fix diagnostics VISCAHW & VISCA4W.
315    
316    checkpoint59o
317    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
318    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
319      move a few statemens out the main loop into separate loops
320    o pkg/shelfice:
321      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
322        (kg/m^2/s), does not break tests, because in verification/isomip,
323        rhoConstFresh=rhoConst (by accident)
324      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
325      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
326        new file model/src/seawater.F, so that they are available for all pkgs.
327      - convert potential temperature into in-situ temperature. This changes the
328        isomip tests => update tests
329    o add a flag writePickupAtEnd (default=true) to be able to suppress
330      writing a pickup at the last timestep
331    o tools/mpack-1.6 :
332      - disable automake (not working) and autoconf (not needed).
333      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
334        also cleaner with much less compilation warnings.
335    o pkg/profiles:
336      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
337      (for "less than 32 characters name" compiler requirement)
338    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
339      conditions that have a different sampling frequency than S/T/U/V obcs
340    o pkg/diagnostics (stats-diags):
341      - fix global Min/Max in case 1 processor get only empty tiles
342    o genmake2: replace (4 times)
343         make genmake_tc_1.o >> genmake_warnings 2>&1
344      with
345         COMM="$CC $CFLAGS -c genmake_tc_1.c"
346         echo $COMM >> genmake_warnings
347         $COMM >> genmake_warnings 2>&1
348      to make genmake2 always see the value of CC as specified in the optfile.
349    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
350      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
351      - modify verification advect_cs test to test SOM-advection on CS-grid.
352    o pkg/ctrl:
353      - Rewrite of ctrl_map_ini_ecco.F,
354        introducing a generic routine (ctrl_map_ini_gen.F).
355      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
356    
357    checkpoint59n
358    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
359      number in dedicate array "hdiag":
360      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
361        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
362      - many small changes (integer format) for large number of diagnostics
363      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
364        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
365    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
366      usingSphericalGrid, this allows to define the rotated grid coordinates
367      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
368      geographical coordinates according to the inverse of the rotation defined
369      by the Euler angles, so that Coriolis parameter and online-interpolation by
370      exf works with the geographical coordinates on XC/YC/XG/YG.
371      Naturally, this feature does not work with all packages, so some
372      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
373      profiles), because there the coordinates are assumed to be regular
374      spherical grid coordinates.
375    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
376      - introduce isopycnal diffusion coefficient control.
377    o tools/adjoint_options:
378      - additional control vector components.
379    o pkg/mnc: have mnc create marginally meaning full coordinate variables
380      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
381    o pkg/mypackage:
382      - add example of read/write pickup for state-var ;
383      - add entry points to the main code for state-vars diags & write-pickup.
384    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
385      transitions for useExfYearlyFields
386      - add new subroutine that determines the file to read from for
387        use*YearlyFields = .TRUE. and .FALSE.
388      - add a verification experiment to global_with_exf that tests
389        useExfYearlyFields with USE_EXF_INTERPOLATION defined
390    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
391      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
392      subroutines (which could be generated from a template, because they are
393      almost identical), for now they are included in obcs_prescribe_read.F for
394      simplicity
395    o pkg/exf:
396      - add a little more diagnostic to exf_interp_read (in analogy to
397        mds_read_field, can be turned off with debugLevel < debugLevA=1)
398      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
399        ugly but fast by unrolling short inner loops, inserting a unroll=8
400        directive in routine lagran, and splitting a loop and making do while the
401        outermost loop (the latter requires the intoduction of index arrays)
402    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
403    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
404      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
405    o verification/seaice_obcs: updated for restart test and latest options
406    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
407      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
408      for now this is only available for the C-grid code and also within
409      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
410    
411    checkpoint59m
412    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
413      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
414    o gad_som : fix flux output (& diagnostics) to have same units as other  
415      advection scheme fluxes (was previously multiplied by deltaT).  
416    o added verification/seaice_obcs both to test seaice open boundaries
417      and to provide an example matlab scrpt for generating them
418    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
419    o pkg/salt_plume: clean up salt_plume_frac.F to
420      remove redundancy in PlumeMethod 1 and 4
421    o pkg/kpp: added saltplume diagnostics
422    o pkg/obcs and pkg/seaice:
423      - do not set uice and vice to zero when OB*icefile are unspecified
424      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
425      - moved seaice tracer obcs after call to seaice_growth
426    o pkg/salt_plume: added various options for salt plume depth
427      criterion and for vertical distribution of the salt
428    
429    checkpoint59l
430    o pkg/ptracers: new version of ptracers pickup:
431      read meta file and write only fields which are needed to restart.
432      ( same logic as main pickup file ; also using pickupStrictlyMatch )
433    o pkg/seaice:
434      - add timescale for melting due to warm mixed layer as a means of
435        setting SEAICE_availHeatFrac more conveniently
436      - add a CPP-flag/runtime parameter check for flooding algorithm
437      - reformulated availHeat in seaice_growth.F to be independent of AREA
438    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
439      unit changes
440    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
441    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
442      SX vector computer.
443    o pkg/seaice:
444      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
445        seaice forcing fields can now be read only through pkg/exf
446      - removed some unused halos
447    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
448    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
449      or U/VICE from U/VWIND before computing U/VSTRESS
450    
451    checkpoint59k
452    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
453      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
454    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
455      all experiments pass when compile with un-initialised var. checking option.
456    o added pkg/salt_plume
457    o script to test restart (for now, in MITgcm_contrib/jmc_script)
458    o pkg/seaice: new read/write pickup version.
459      read meta file and write only fields which are needed to restart.
460      ( same logic as main pickup file ; also using pickupStrictlyMatch )
461    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
462    o lab_sea.hb87: modify the domain & update output.hb87.txt :
463      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
464      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
465      process. Fixed here by closing the domain at the Northern boundary.
466    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
467    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
468      a set of consecutive levels in/from a 3-D array.
469    o pkg/ptracers:
470      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
471      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
472    
473    checkpoint59j
474    o in pkgs: dic, obcs, offline, rbcs:
475      standard way to compute coeff. for time interpolation between 2 time reccords
476      which retains full precision (& make results less dependent on compiler).
477      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
478    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
479      packages instead of reading ice cover and wind speed separately
480    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
481     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
482      to allow to compile customized code before the update)
483    o cleaning-up:
484      - fix CPP instruction syntax in pkg/obcs
485      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
486        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
487      - fix some threads issue in IO parts.
488    o pkg/dic:
489      - add tons of "_d 0" (--> much better testreports !)
490       and then update outputs of tutorial_global_oce_biogeo
491    o pkg/mom_fluxform:
492      add a special version of momentum advection intended to conserve momentum
493      next to a bathymetry step or a coastline edge. (default = off = #undef)
494    o new read/write pickup version:
495      - for now, only implemented for main (mdsio) pickup file.
496      - write out only what is needed to restart; merge pickup_nh , pickup_ph
497        and main pickup together.
498      - read meta file; read only what is needed to restart; stop if a field
499        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
500        if it make sense (even if the restart is not perfect).
501      - if no meta file, assume that pickup to read corresponds exactly to
502        a pickup that would currently be written.
503      - read pickup written in the old format (until checkpoint59i) if it
504        recognizes an old meta file (no field-list).
505      - add a meta file in exp. which starts from a pickup: 2 cases:
506        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
507         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
508        b) a meta file describing the content of the associated pickup file
509         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
510    o pkg/mdsio & pkg/rw:
511      - new routine to read a meta file ; new set of routine to read
512        Multiple-fields file (with meta file).
513    o added open boundary conditions capability for seaice
514        HSNOW, HSALT, UICE, and VICE
515    
516    checkpoint59i
517    o adjoint:
518      * fix multiDimAdvection adjoint
519        (partial recomputation problem by TAF for fVerT(:,:,kDown)
520        and comlev1 size definition (maxpass vs. max. number of tracers)
521      * verification/global_ocean.90x45x15 adjoint now tests
522        NLFS and multiDimAdvection using DST3 (=30)
523      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
524    o pkg/kpp: add "_d 0" to real constant (if missing);
525      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
526      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
527    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
528      for internal parameters related to restart process (formerly from PARAMS.h)
529      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
530    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
531      as argument. (only atm2d & obcs write_pickup have not yet been updated)
532    o pkg/monitor:
533      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
534      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
535      - account for deep Atmosphere factor and density factor (anelastic)
536    o added open boundary conditions capability for seaice HEFF and AREA
537    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
538      thermodynamics
539      - requires a little reorganization, which affects the testreport results
540        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
541        so that now the conservative form is tested
542      - add a few comments
543    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
544    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
545    o add new diagnostics to seaice: advective, diffusive fluxes (only for
546      multidim-advection, for scheme 2 they are not filled) and transports,
547      thermodynamic growth rates
548    o change units of EmPmR (inside the code, + within coupling interface)
549      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
550      Affects results @ truncation level (cg2d match) and update output of
551       experiments: lab_sea(6), global_ocean.90x40x15(10),
552      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
553      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
554      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
555      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
556    
557    checkpoint59h
558    o pkg/exf:
559      - improve vectorization by moving if-statement out of loops in
560        exf_mapfields, exf_radiation
561      - exf_bulkformulae.F: introduce 2D fields and vectorize code
562    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
563    o testreport:
564      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
565        monitor & update offline_exf_seaice exp. output.
566      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
567    o pkg/seaice:
568      - bug fix in the evp solver: boundary conditions were affected be
569        masking of zMax/zMin (changes results)
570      - minor bug fix in boundary conditions in seaice_calc_strainrates
571        (changes results for no_slip)
572      - seaice_lsr.F: make interpolation of eta dependent on boundaries
573      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
574      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
575        stress formulation and no-slip boundary conditions
576    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
577      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
578    o pkg/seaice: a first HSALT time stepping equation has been checked in
579    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
580      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
581      without requiring DO-IF statements
582    o pkg/thsice:
583      use continuous power-law function for partition of energy between lateral
584      melting/freezing and thinning/thickening ; old code using step function
585      still available with #undef THSICE_FRACEN_POWERLAW
586      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
587    o testreport: change AD testing : check against results/output_adm.txt
588      using same scripts as for forward test.
589    
590    checkpoint59g
591    o adjoint testing: in preparation for changing testreport:
592      - output format: cost and grad written on separated lines
593      - ad output results in directory "results" (instead of "results_ad")
594    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
595    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
596    o pkg/ecco: allow user defined cost function contributions
597    o testreport:
598      Allow to choose (per experiment) the list of tested output variables
599       and the main variable (used to issue a pass/FAIL ) ;
600      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
601      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
602      Also modify printing of summary:
603       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
604       b) echo the list of tested variables in the individual summary.txt of
605          each experiment.
606    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
607      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
608      (but still depend on the tile decompostion of the domain).
609    o pkg/seaice: change a discretization detail to make the B-grid code
610      "more symmetric". This change is likely to remove all "ridges/leads" that
611      where quasi-aligned with the grid in B-grid solutions. It may also be
612      the solution to the stress coupling issues with the B-grid.
613    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
614      remove .cvsignore from input dir. (since testreport no longer run here).
615    o pkg/thsice:
616     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
617     - fix reshaping of sea-ice just after advection:
618       melt all the ice only if ice-volume is too small.
619     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
620       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
621     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
622    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
623      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
624    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
625      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
626      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
627      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
628      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
629      -> update output.txt
630    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
631     this affects truncation error: -> update output.txt of exp:
632      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
633      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
634    
635    checkpoint59f
636    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
637    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
638      a bounded range (in forward mode)
639    o pkg/ecco, ctrl, autodiff and mom_common:
640     internal parameter controls, completements of implementations
641    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
642    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
643      (not seem any difference in testing results).
644    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
645       at face corners.
646    o pkg/generic_advdiff:
647     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
648      loop range indices for computing vertical advection tendency
649      and do the calculation in the interior only (no overlap) ;
650      for now, only implemented for SOM advection (to save CPU time).
651     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
652    o exch2 adjoint
653      First set of changes:
654      - add exch2 hand-written adjoint templates
655      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
656        This will require cleanup in pkg/autodiff/*.F
657        (changed routines currently kept separate in verif. code/)
658      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
659        that used to hide exch2 or cubed-sphere specific code
660        (commented via 'cph-exch2')
661    o pkg/seaice
662      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
663    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
664       output of global_ocean.cs32x15.thsice .
665    
666    checkpoint59e
667    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
668      for B-grid vector (not yet tested) and C-grid vector (<- only used
669      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
670    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
671      (#ifdef ALLOW_SALT_PLUME)
672    o gather_2d/scatter_2d: removed halo regions
673    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
674      scheme and the corresponding test case (under front_relax dir). For now,
675      only available with Skew-flux form and not yet tested in realistic set-up.
676      adjoint: store directives updated, but gradient checks deteriorated,
677      so maybe GM/Redi adjoint is now broken.
678    o seaice adjoint
679      * add AREA, HEFF, HSNOW as control variable
680        (should not change lab_sea results)
681      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
682    o pkg/seaice:
683      * added computation of saltFlux in seaice_growth;
684        For time being, sea ice salinity is assumed constant
685        contribution of snow flooding to freshening of sea ice is neglected.
686        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
687        defaults to 0.0 in order to maintain backward compatibility.
688        Typical values for SEAICE_salinity are 4 to 10 g/kg.
689      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
690      * added SEAICE_availHeatFrac, which specifies fraction of surface level
691        heat content used to melt or grow ice
692      * commented out cap of HICE: it helps keep ice thinner
693      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
694      * applied OBCS T/S mask to HEFFM sea ice mask
695    
696    checkpoint59d
697    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
698     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
699     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
700    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
701     and change default value of parameter "GM_Small_Number";
702     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
703       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
704       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
705    o pkg/ecco: cost function when applying pkg/smooth to controls
706    o pkg/ctrl: add forcingPrecond run time parameter
707    o pkg/seaice:
708     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
709     - fix bug in metric terms of u-equation in LSR solver (implicit part),
710       changes verification/lab_sea
711     - rearrange implicit part of u-equation in LSR solver to make it easier to
712       read, understand, and debug. This causes changes at the truncation level.
713     - fix (serious) bug in the boundary conditions (sign error in the implicit
714       part) of the LSR solver. Changes all LSR results.
715     - fixed problem with HSNOW initialization to avoid thick snow when AREA
716       is initilized with small values - does not change lab_sea results.
717     - added HsnowFile initialization capability
718    o pkg/smooth: addition to model/src and pkg/ctrl so allow
719     initialization of pkg/smooth and application to control vector
720    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
721    o dependencies: pkg/profiles requires pkg/cal
722    o pkg/profiles:
723     - added option ALLOW_PROFILES_GENERICGRID
724         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
725         that interpolation information (grid points and coefficients) is provided
726         within the netcdf input files.
727         -> sample matlab scripts can be found in MITgcm_contrib/gael
728         that allow you to prepare netcdf input files.
729     - also modified: cleaner include statements, cleaner error print statements,
730       cleaner stops when error, and more tests of the netcdf input files consistency.
731    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
732    o pkg/seaice:
733     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
734       requires a new routine: seaice_diagnostics_fill.F
735     - make sure that seaice does not move if not forced (pressure replacement
736       method, Hibler and Ip, 1995), changes results
737     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
738     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
739       It is turned off by default (=-1.), because it changes the results.
740     - make it possible to read AREA from a file, too.
741    
742    checkpoint59c
743    o add S/R and diagnostics for oceanic mixed-layer depth
744    o move GMRedi call after all vertical mixing schemes (including KPP)
745    o pkg/thsice:
746     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
747      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
748    o pkg/obcs:
749     - bug fix for balance code
750    o pkg/seaice:
751      - allow values of SEAICE_elasticParm > 1
752      - add new parameter SEAICE_evpTauRelax as an alternative
753        to SEAICE_elasticParm
754      - make lsr boundary conditions free slip (by default), changes result
755      - add code for no slip boundary conditions for lsr
756      - set minimum of zeta to zero (and not 4e8) (changes results)
757      - add a cap on AREA after advecting AREA if seaice_growth is not called
758    o change calculation of Visbeck K:
759      - no longer depend on tapering scheme; instead, compute slope (limited
760        by GM_maxSlope). this is equivalent to what was comuted before with
761        clipping or linear tappering.
762      - fix vertical averaging (wrong by 1/2 level)
763      - leave the old version (but will not be maintained) within
764        #ifdef OLD_VISBECK_CALC / #endif
765      - update output of exp. ideal_2D_oce
766    o change error catch in calc_r_star to improve vectorization
767    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
768      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
769    o adjoint:
770      Re-organized adjoint checkpointing according to Matt Mazloff
771      (but with modifs/completions/cleanups)
772      Storing is now bundled into large arrays to optimized I/O
773      (and second step in cleanup of the_main_loop)
774    
775    checkpoint59b
776    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
777      - export/import (between ocean & coupler) fields needed for ocean DIC.
778    o pkg/seaice:
779      - get rid of three more exchanges seaice_calc_viscosities (required
780        different loop boundaries in seaice_lsr and seaice_ocean_stress)
781      - bug fix in seaice_ocean_stress (update of lab_sea required)
782      - reduce loop boundaries to necessary minimum also in seaice_evp
783      - go back to the old way of computing deltaC/Z as the adjoint likes that
784        better
785    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
786      passive tracer to an Age Tracer) + update output.txt
787    o pkg/exf:
788      - implement A-grid / C-grid selection for wind-stress input files.
789      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
790      for now, in exf_bulk_largeyeager04.F only :
791      - change implementation for case where windspeed + 2. components wind-stress
792        are read-in. AND use rhoConstFresh to convert evap.
793    o pkg/seaice:
794      - use correct EXCH_UV for wind-forcing (on A-grid).
795      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
796        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
797    o pkg/exf:
798      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
799      EXF_INTERPOLATION:
800      - merge global_with_exf/code version of exf_interp_read.F
801        to the main code ;
802      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
803        reading the file ; Important: This options needs to be defined to recover
804        previous code.
805        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
806      - no longer loose real*8 precision along the way when using exf_iprec=64.
807    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
808      - change discretisation of evp-solver in order to avoid another exchange
809        (changes lab_sea) and clean up a little
810      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
811        help the adjoint (this also changes the results slightly)
812      - add a few "_d 0" where they had been missing in seaice_evp.F
813      - cleaning up: remove unused seaice_calc_rhs.F
814    o pkg/exf: some cleaning-up:
815      - change various "constants" into runtime parameters
816      - cleaned-up Large&Yeager04 routine which should eventually
817        replace exf_bulkformulae.F (changed names of S/R and CPP)
818        and merged various ALLOW_ATM_WIND options
819     only used with thsice pkg (in thsice_get_exf.F):
820      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
821        which are used when useStabilityFct_overIce=TRUE (= the default)
822      - change default values of ice & snow emissivity and scale downward LW
823        by ice & snow emissivity.
824    o pkg/thsice:
825     fix few little problems, in thsice_calc_thickn.F:
826      - growth vertically (and not laterally) if iceFrac == iceMaskMax
827      - melt only laterally if hIce < hThinIce (as the comments say)
828      and in thsice_extend.F:
829      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
830      - start to form ice as soon as the minimum ice-volume is reachable.
831     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
832      and cpl_aim+ocn
833    o pkg/kpp
834     - move computation of surface related input fields to KPP into a new
835       subroutine kpp_forcing_surf.F
836     - remove wrong (within bi,bj loops) EXCH calls.
837     - little cleaning (add argument myThid in last position, cvs header ...)
838     - for now, fix conservation problem by exchanging KPPviscAz (may not
839       be the best fix)
840    o pkg/seaice
841     - check for inconsistent evp parameter/cpp-flag combination
842     - remove leftover errIO flat for obsolete name list error handling
843    o OpenAD
844     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
845    
846    checkpoint59a
847    o pkg/seaice: some parameter clarifications and a little bit of clean up
848    o pkg/thsice: rename run-time parameters:
849       himin       -> hIceMin
850       himin0      -> hThinIce
851       hihig       -> hThickIce
852       i0          -> i0swFrac
853       transCoef   -> bMeltCoef
854       frac_energy -> fracMelting
855      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
856       with default values (for now) that do not change the results.
857      remove old version of thsice vars advection in pkg/seaice.
858    o in FFIELDS.h:
859      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
860      - make pLoad & sIceLoad always available (but still only used if
861         ATMOSPHERIC_LOADING is #define).
862    o pkg/kpp: replaced _KPP_RL with _RL
863    o bug fixes for vertical diffusivity computations when both KPP and
864        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
865        are no longer updating the vertical diffusivity array
866        (passed as argument) but are (re-) setting those arrays.
867    o pkg/seaice: fix bug in evp solver, while doing that
868      - change (improve?) discretization of stress computations for both
869        cgrid-lsr and evp solver
870      - add a new routine to compute strain rates
871      - the above changes lab_sea results
872      - add no slip conditions for evp solver (off by default), lsr-version
873        may follow
874      - fix exchange for shear at Z-points (does not change lab_sea)
875      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
876        (to force the user to pick a time step since there is not "safe" way
877        of choosing it)
878      - add principal stress diagnostics
879      - rearrange fields for evp a little to avoid having to call a: too many
880        exchanges and b: exchanges for stress trensor components which we do
881        not have.
882      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
883        of evp, complete rewrite for lsr case (latter is does not yet work
884        in all cases)
885    o pkg/kpp: add code to have mixing in shelf ice caverns
886      - add myThid to all kpp routines (long overdue)
887    
888    checkpoint59
889    o pkg/exf:
890      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
891        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
892      - move exf header files from lower_case.h to UPPER_CASE.h ;
893        add missing cvs Header & Name
894      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
895      - add namelist param. selectStressGridPosition, exf_monFreq
896      - retire many _CLIM routines, and remove data.exf_clim
897        + params moved to data.exf
898        + climsst, climsss now handled by exf_set_gen, i.e.
899          climss?period=0 refers to constant field,
900          climss?period=-12 to monthly forcing
901      - split up namelists in data.exf
902    o pkg/seaice:
903      - remove seaice_exch and seaice_exch_uv
904      - remove superfluous exchange of theta
905      - add myThid to seaice_budget_ocean/ice
906      - add new interface for atmospheric wind forcing (C-grid only)
907        + new routine
908        + two new field (taux, tauy for stress over ice)
909        + removed one global field (DAIRN) for C-grid case only
910    o pkg/thsise
911      - 2nd set of modifs for thsice adjoint in conjunction with exf
912    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
913    
914    checkpoint58y_post
915    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
916      vertical diffusivity, similar to that in MOM4; turned on using
917      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
918      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
919    o Added capability for 3D specification of background vertical diffusion
920      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
921      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
922      "data" file that contains the 3D vertical diffusivity coefficients.
923    o ice dynamics (pkg/seaice) with thsice thermodynamics:
924      - add code within pkg thsice to advect & diffuse sea-ice fields
925      similar to (and will replace) what has been added in  seaice_advdiff.F,
926      but: - conserving Mass, Heat & Salt.
927           - better when using non-linear advection scheme (not yet fully tested)
928           - can also be used in atmospheric set-up (for now, only the diffusion).
929    
930    checkpoint58x_post
931    o IO option for global-file compact format:
932      - add options when generating topology (utils/exch2/matlab-topology-generator)
933      - add I/O capability (pkg/mdsio).
934      - adapt utils/matlab/rdmds.m to read this format.
935      for now long-line format not yet supported by pkg/mdsio (& exch2).
936    o shelfice: add a few diagnostics
937    
938    checkpoint58w_post
939    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
940      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
941      (and replace horiVertRatio in NH code).
942      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
943                         and tutorial_plume_on_slope (sensitive to truncation)
944    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
945      directly to drive seaice model (C-grid only)
946    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
947     - reintroduce computation of wind from stress,
948     - compute tau (in exf_bulkformulae.F) from windstress averaged to
949       mass points to avoid tau = 0
950     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
951    o rdmnc.m: make it work with "global" files created with gluemnc
952    o rdmnc.m : some improvements in dealing with singleton dimension
953      (tested on all testreport mnc output files).
954    o genmake2: disable pkg/profiles if netcdf test fails.
955    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
956    o move call to cal_readparms up to make calendar parameters/variable available
957      to all packages
958    
959    checkpoint58v_post
960    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
961      useDynP_inEos_Zc tested.
962    o pkg/exf: changes to properly interpolate/mask/scale initial fields
963    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
964      and portions thereof.  See read_cs.txt for description and examples.
965    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
966      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
967      following the great-circle arc between those 2 points.
968    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
969      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
970    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
971     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
972     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
973     - still needs work (not working with some options ; efficiency to improve)
974       and serious testing.
975     - use this scheme for temperature & salinity in 2 advection test exp.:
976       advect_xy & advect_xz, respectively.
977    
978    checkpoint58u_post
979    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
980    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
981    o testreport: add option "-skipdir" to skip some test.
982    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
983      momentum calculation.
984    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
985    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
986      remove checkpoint.F and the_correction_step.F (no longer used);
987      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
988    o add option (linFSConserveTr) to correct for tracer source/sink due to
989      Linear Free surface
990    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
991    o pkg/thsice: fix reading mnc-pickups
992    
993    checkpoint58t_post
994    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
995    o pkg/mdsio:
996     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
997       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
998       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
999     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1000     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1001       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1002     - new S/R (to replace MDSWRITEMETA), which allows to write more
1003       informations (variable names, time ...) to meta files.
1004     - modify rdmds.m to give back the meta file content.
1005    o pkg/diagnostics: change vertical interpolation to be safer, and more
1006       flexible (define p-levels to interpolate to in data.diagnostics);
1007      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1008       diagnostic pointer.
1009    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1010    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1011    o fix multi-category seaice:
1012     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1013       SEAICE_MULTICATEGORY
1014     - fix short wave heat flux
1015    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1016       and allow to use EVP solver. Change forward lab_sea: test both EVP
1017       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1018    o Initial check-in of lab_sea adjoint
1019      (very similar to natl_box_adjoint/code_seaice)
1020      * used C-grid and EVP solver
1021      * used KPP, GM/Redi
1022      * uses inAdExact=.TRUE.
1023      * gradient checks fail for both ADM and TLM
1024        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1025        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1026        issue is related to forward mismatch between g77 an ifort
1027    o pkg/seaice: overhaul of thermodynamics
1028     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1029     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1030     - move a few global fields out of SEAICE.h into seaice_growth.F and
1031       make them 2D (FICE/QNETO/ ...)
1032     - remove FO (it is the same as QNETO)
1033     - introduce a few local fields to avoid modifying external fields such
1034       as atemp, etc.
1035    
1036    checkpoint58s_post
1037    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1038      changed exf_set_gen.F so that
1039        genperiod=0 means input file is one time-constant field and
1040        genperiod=-12 means input file contains 12 monthly means
1041    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1042      this affects truncation error ; generate new output file for exp. which
1043      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1044        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1045        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1046        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1047        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1048        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1049    o start implementation of deep-atmosphere and anelastic formulation
1050    o verification: remove 2nd copy of input files and use script "prepare_run"
1051      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1052    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1053    o profiles: fix for multithreaded case
1054    
1055    o diagnostics: rename few diags:
1056      s/'PRESSURE'/'RCENTER '/g
1057      s/'TICE    '/'oceFreez'/g
1058      s/'TAUX    '/'oceTAUX '/g
1059      s/'TAUY    '/'oceTAUY '/g
1060      s/'SWFLUX  '/'oceQsw  '/g
1061      s/DIFx/DFxE/g
1062      s/DIFy/DFyE/g
1063      and add few ocean-forcing diagnostics:
1064      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
1065    o modifications to pkg/seaice/growth.F and budget.F, which change results of
1066      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
1067      as actual snow thickness.  It now refers everywhere to effective snow
1068      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
1069    
1070    checkpoint58r_post
1071    o modifications to pkg/seaice/growth.F, which change results of
1072      lab_sea experiment: fixes pertain to melting snow over open water, to
1073      masking EVAP under sea ice, and to using the correct AREA variable for
1074      computations of EVAP, PRECIP, HSNOW, and GHEFF
1075    o add ability to read bathy, salt, and theta using MNC (off by def)
1076    o add flooding algorithm and advection of HSNOW for pkg/seaice;
1077      both are turned off by default and do no change any results
1078    o seaice advection with pkg/thsice: a step toward the use of non-linear
1079      advection scheme, but #ifdef or commented out for now (requires more EXCH).
1080    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
1081      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
1082      in natl_box (affects results @ truncation level: update output.txt)
1083    o multi-threading and IO:
1084      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
1085      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
1086        (needed to work with SingleCpuIO): tested in all verif. exp.
1087    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
1088      affects the results (but none of the verification test uses this scheme).
1089    o Adding some pkg/diagnostics capability to pkg/seaice
1090      (will certainly be subject to changes)
1091    o ctrl: adding new control variables:
1092      lwflux, lwdown, evap, snowprecip, apressure, runoff
1093    
1094    checkpoint58q_post
1095    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
1096      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
1097      high_res_cube configuration by 4% on Columbia.
1098    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
1099      add (in global_with_exf/code) a version of EXF_INTERP_READ without
1100      dynamical allocation (seems to work in multi-threaded).
1101    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
1102      single CPU io) so that TAF does not have to see EESUPPORT.h
1103    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
1104    
1105    checkpoint58p_post
1106    o obcs: stop if obcs is used with useCDscheme = .true.
1107    o shelfice:
1108     - fix a sign error so that no slip at shelfice interface works
1109     - remove stop for combination non-hydrostatic code and shelfice. That does
1110       not mean, that the results are correct, but at least they are numerically
1111       stable
1112    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
1113    o added adjoint exch routined for all exch*3d* routines
1114      and updated flow directives
1115    
1116    checkpoint58o_post
1117    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
1118      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
1119    o change controling S/R for writing pickup file (new S/R do_write_pickup)
1120      and clean-up reading/writing of pickup files.
1121    o fix local version of read/write pickup (NH part) in rotating_tank/code
1122    o simplify EXCH interface:
1123     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1124     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1125    o added the regrid package
1126    o shelfice:
1127     - add a simple boundary layer scheme to reduce noise
1128     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1129    
1130    checkpoint58n_post
1131    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1132       local variable (not in common block).
1133    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1134      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1135      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1136        to work with SingleCpuIO.
1137    o add "_d 0" to real constant of pkg/cfc subroutines ;
1138       update exp. cfc_exemple & tutorial_cfc_offline output files.
1139    o multi-threading and IO:
1140      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1141        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1142      - barrier before and after reading.
1143      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1144      - avoid using MDS_WRITELOCAL for LAND pkg output.
1145      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1146        common-block variables ; Allows multi-threading with master-thread IO.
1147    o change default MAX_NO_THREADS from 32 to 4 ;
1148      and stop cleanly when MAX_NO_THREADS is too small.
1149    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1150    
1151    checkpoint58m_post
1152    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1153       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1154    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1155       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1156       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1157    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1158        add MITgcm_tutorials (= code + all the tutorials)
1159    o ecco, option to compute cost for total ssh (mean+anom)
1160    o consistent with addition of ptracer and ssh in pkg/profiles
1161    o profiles: adding ptracer and ssh
1162    o testreport: change multi-test output-file name
1163      (from output.txt.{name} to output.{name}.txt)
1164    o profiles: now ok for mutli-tiles case
1165    o seaice: add 4 parameters for different advection schemes for area,
1166      (effective) seaice thickness, enthalphy, and snow height. Their default
1167      is the standard parameter SEAICEadvScheme
1168    o calc_gw:
1169     - add cosFacU in zonal viscous flux (harmonic.visc.).
1170     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1171       of tutorial_plume_on_slope.
1172    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1173    o calc_gw: true flux-form, account for horizontal grid spacing.
1174      update rotating_tank results, but not plume_on_slope (affected at
1175      truncation level, 11 digits).
1176    
1177    checkpoint58l_post
1178    o calc_gw:
1179     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1180     - remove side-drag for now (need to fix it); update plume_on_slope results.
1181     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
1182    o commit code to make SST/SSS weights spatially variable
1183      (based on either variable in-situ or variable initial T/S weights)
1184    o pkg/ecco:
1185      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
1186        now based on horizontally varying weights wthetaLev, wsaltLev
1187      * cost_averagesflags now returns year indices in addition to day, month
1188      * sflux balance is performed on annual basis
1189        (sflxumm, sfluxmm2, bal_sfluxmm)
1190      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
1191        including separate counting and multipliers
1192    o pkg/rbcs
1193      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
1194    
1195    checkpoint58k_post
1196    o testreport:
1197     - always build in dir. "build" (if not there, mkdir build instead of building
1198       & running in input)
1199     - run in dir run (if it exists), in build otherwise.
1200     - call prepare_run (if input/prepare_run exists)
1201     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1202    o pkg/exf modifications to interpolation and rotation routines for more
1203       reasonable treatment of North Pole singularity: for tracers North Pole
1204       value is set to northernmost zonal-mean value, for zonal velocity it is
1205       set to zero, and for meridional velocity it is set to northernmost value.
1206    o pkg/exf/exf_check_range.F
1207     - add tile index to diagnostics and move stop statement to the very
1208       end of the routine.
1209    o pkg/diagnostics: (diagnostics_main_init.F)
1210      define title of isomorphic variables according to the current config.
1211    o pkg/thsice with pkg/seaice dynamics:
1212    - fix domain of computation (interior only, required for exf) and do exchanges
1213    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1214    o towards a standard way of dealing with multi-threading in MONITOR
1215      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1216    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1217       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1218    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1219    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1220    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1221       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1222    o tracer advection:
1223     - clean-up and simplify calc_common_factors.F
1224     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1225       advection subroutine (but still not used within DST advection S/R)
1226    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1227    
1228    checkpoint58j_post
1229    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1230      from file (collects calls previously in FORWARD_STEP)
1231    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1232    o adjoint store dir. adjusted accordingly
1233    o genmake2
1234      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1235    
1236    checkpoint58i_post
1237    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1238      on wind stress (SEAICEstressFactor defaults to 1.)
1239    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1240      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1241    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1242      on CS-grid: no longer loosing mass.
1243    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1244    o pkg/ggl90: fix sloppy output and fix a bug
1245    o pkg/seaice: added SEAICEuseEVPpickup parameter
1246      - Set to false in order to start EVP solver with
1247        non-EVP pickup files when using SEAICEuseEVP
1248      - fix sign error in diffusion in seaice_calc_rhs
1249    
1250    checkpoint58h_post
1251    * Modifications for bottom topography control
1252      o replace hFacC by _hFacC at various places
1253      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1254      o add non-self-adjoint cg2d_nsa
1255      o update autodiff support routines
1256      o re-initialise hfac after ctrl_depth_ini
1257      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1258    * Adding verification for 5x5 box (4-layer) bottom topography control
1259    
1260    checkpoint58g_post
1261    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1262       used for mean seasonal cycle, mean diurnal cycle); add an example
1263       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1264    o pkg/ggl90:
1265      - add parameter (minimum surface kinetic energy)
1266      - fix bug (avoiding division by zero)
1267    o couple pkg/thsice to pkg/seaice:
1268      - modify advection in seaice to accomodate new scalar fields to be advected
1269      - only muliDimAdection scheme work with seaice/thsice
1270      - mapping of thsice-variables to seaice-variables, back and forth
1271      - does not break the verification experiments, but does not give the
1272        desired results either
1273    o pkg/seaice
1274      - make (default) second order advection a bit less confusing?
1275    
1276    checkpoint58f_post
1277    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1278      to pkg/seaice):
1279      - new routines thsice_map_exf and thsice_get_exf provide the interface
1280      - add an additional formal parameter to thsice_solve4temp
1281    o pkg/exf:
1282      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1283      - correct Stefan-Boltzmann constant
1284      - new parameter for longwave surface emittance
1285      - separate some stuff from exf_bulkformulae into new routines  
1286        exf_radiation, exf_wind
1287      - add new parameters and constants: longwave emissivity for ocean, ice
1288        and snow, evaporation parameters over ice
1289      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1290        either wind from stress or stress from wind
1291    o pkg/thSIce:
1292    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1293    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1294       and THSICE_CALC_THICKN
1295    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1296    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1297      to make debugging easier.
1298    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1299    o pkg/bulk_force:
1300      - clean-up comments and parameters ;
1301      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1302    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1303      generate new output for test-experiment: aim.5l_cs.thSI
1304    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1305      testreport accordingly
1306    
1307    checkpoint58e_post
1308    o SEAICE_CGRID adjoint done
1309    o R_STAR adjoint implemented.
1310      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1311      * need to sort out init. of h0facc, etc.
1312    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1313      to be able to use it in pure forward.
1314    
1315    checkpoint58d_post
1316    o upgrade simple test-experiment to tutorial example:
1317     step.1: duplicate the experiment and (step.2) will remove the old copy.
1318      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1319      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1320      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1321      tutorial_global_oce_biogeo    <- copy of dic_example
1322      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1323      tutorial_plume_on_slope       <- copy of plume_on_slope
1324      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1325      tutorial_global_oce_optim     <- empty for now (David ?)
1326      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1327     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1328    o correct a sign problem in cost_scat.F
1329    o obcs and ptracers: fix boundary conditions for advections schemes
1330      with larger stencil

1332    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1333      completeness
1334    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1335      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1336    o ptracers adjoint:
1337      * avoid extensive recomputatations
1338      * fix missing re-init. of gptr (missed by TAF)
1339    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
1340      me to turn off the excessive output to STDOUT that this package produces
1341    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1342      and add those terms in Vector-Invariant formulation.
1343    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1344      if the control period (xx_hfluxperiod etc) is 0
1345    o in profiles pkg, clean routines and fix details
1346    o in ecco pkg, reading ssh data:
1347      fix problem in case the model does not start at iter0=0
1348    o fix mnc-pickup/restart for ptracers
1349    o new package prifiles:
1350      code to compute profile-based cost by Gael Forget
1351      (modifs in ecco, ctrl, autodiff)
1352    o Benign bug fix in initialization (spotted by M. Mazloff) of
1353      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1354    
1355    checkpoint58c_post
1356    o adjoint: finish NLFS adjoint and provide reference output in
1357      verification/global_ocean.90x40x15/results_ad_nlfs
1358    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1359      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1360      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1361      with SEAICE_CGRID defined.
1362    o move calendarDumps from "data" to "data.cal" and clean-up the code
1363      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1364    o add useEXF & useCAL flags (for now, set in hard-coded way)
1365    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1366      (were missing in NH mode, and wrong in quasihydrostatic mode).
1367      waiting for Chris updated version of calc_gw to add those CALLs.
1368    o fix bug in quasihydrostatic S/R ;
1369      add a test for this option: global_ocean.90x40x15.qshyd
1370    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1371      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1372    o add on/off flag useOffLine for package OFFLINE
1373    o seaice:
1374      - modify advection so that it works also on the C-grid
1375      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1376        problem in multi-tile runs with C-grid
1377      - add flags for clipping ice velocities and/or masking solver forcing
1378      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1379        C-grid solver
1380      - added a few comments to seaice_diffusion.F
1381      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1382        are now exclusive)
1383      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1384        required re-ordering the code a little:
1385       + make DAIRN global variable (defined in SEAICE)
1386       + move computation of the viscosities eta and zeta into a new separate
1387         routine (because I need to recompute them in seaice_ocean_stress.F)
1388    
1389    checkpoint58b_post
1390    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1391      update output.txt of exp. aim.5l_cs.thSI
1392    o various mnc cleanups and improvements:
1393      + shrink lookup tables by factor of ~4
1394      + better error reporting when running out of lookup space
1395      + able to handle longer path/file names (up to 500 chars)
1396    o adjoint:
1397      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1398      - TBD: "hidden" mom_vecinv recomp. in dynamics
1399    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1400     (allow to differentiate between forcing components using new integer flags:
1401      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1402     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1403    o ecco
1404      - enable trend removal from SSH anomaly obs.
1405    o adjoint
1406      - a fix for PmEpR when #undef EXACT_CONSERV
1407      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1408      - try to fix "hidden" recomp. in forward_step for NLFS
1409        (NLFS seems broken sometimes after I checked it in)
1410    o seaice:
1411     - add c-grid version of the dynamic solver:
1412       + three new routines that are the c-grid substitute lsr, dynsolver
1413         and ostres
1414       + put a few fields that were local to dynsolver into global common
1415         blocks, so that I can move the computation of stresses etc into
1416         seaice_lsr (saves coding but may break the adjoint).
1417     - replace more hardwired parameters by runtime parameters
1418     - add ice masks that mask the rhs of the implicit solvers where there
1419       is no ice (commented out in seaice_dynsolver, because i am not sure
1420       if this works properly), eventually this should replace the clipping
1421       of ice velocities in seaice_dynsolver to +/-40cm/s.
1422    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1423      include it only where its needed
1424    o move balancing of fluxes before the call of external_forcing_surf
1425    o seaice:
1426      - correct units of turning angles (now they are really in degrees)
1427      - move computation of GWATX/Y out of main routine into dynsolver
1428      - initialize GWATX/Y in seaice_init
1429    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1430      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1431    o seaice: add runtime flags for turning angles (default to zero)
1432    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1433      and trend from exf forcing and ctrl control adjustments
1434    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1435      (since checkpoint57x_post)
1436    o change the default rotation period to 86164.s = the Earth rotation
1437    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1438      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1439    o seaice advection: add code for choosing between the default (2nd order
1440      central differences) and multiDim advection schemes provided by
1441      pkg/generic_advdiff
1442    o seaice:
1443      - removed all references to SEAICE_GRID.h fields from
1444        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1445        (cubed-sphere configuration will change a little)
1446      - grid computations in seaice_init are obsolete now.
1447      - cleaned up code a little so that is easier to read (hopefully).
1448      - added new (better?) discretizations of default advection and diffusion
1449        (turn on with SEAICEuseFluxForm)
1450      - replace 1 in 3d global fields by kSurface in growth.F
1451      
1452    checkpoint58a_post
1453    o seaice:
1454      - bug fix in advect.F
1455    o shelfice:
1456      - separate shelfice load anomaly from pload (breaks with time
1457        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1458        Its default is 0., but it may be computed more cleverly from (unknown)
1459        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1460        done offline. A good approximation of the pressure load anomaly is
1461        necessary to avoid large initial adjustment processes underneath
1462        deep-reaching shelfice.
1463      - small fix in ISOMIP shelfice_thermodynamics
1464      - add more sophisticated thermodynamics of Hellmer (1989), this is
1465        now the default
1466      - give a few constants more intuitive names
1467    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1468      if bulk formulae are used in long integration (especially EmPmR). Turn
1469      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1470      if balancePrintMean, the imbalance that is substracted is printed to
1471      STDOUT.
1472    o fix bug (typo) in obcs_apply_eta.F
1473    o add a new package shelfice which enables us to model the circulation
1474      underneath shelf-ice with draughts of hundreds of meters.
1475     - works
1476     - to do: + include improved thermodynamics
1477              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1478                instead of new field kTopC
1479              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1480                instead of new field R_shelfIce and new code in ini_depth.F
1481                and ini_mask_etc.F?
1482              + adjust vertical mixing schemes?
1483    o seaice pkg:
1484     - add a cpp-flag to include a simple formula for a salinity dependent
1485       freezing point of sea water at the surface
1486     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1487       meridional stresses are now different (and hopefully correct)
1488    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1489       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1490       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1491    o pkg/diagnostics: add options and parameters for regional-statistics
1492       diagnostics ; define regions by reading a region-mask from a file
1493       (might add other options later)
1494    o pkg/bulk_force:
1495     - add option and parameters to use AIM surface-flux formulae.
1496     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1497       others forcing fields (defined in PARM05, parameter file "data") are loaded
1498       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1499     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1500     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1501     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1502       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1503     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1504    
1505    checkpoint58
1506    o add "--embed-source" option to genmake2 which, when the supporting
1507      tools can be compiled (as determined by genmake2) will turn on the
1508      embed_files package which then embeds the entire MITgcm source code
1509      (*.[fFhc] + Makefile) used for the build within the executable
1510      - requested by CNH but off by default
1511      - adds a paltry <9MB to the mitgcmuv executable in most cases
1512      - only writes the output when useEMBEDSRC in eedata is true
1513    o clean up 3-dim. relaxation codes:
1514      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1515      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1516      * Thanks to Tom Haine for testing!
1517    
1518    checkpoint57z_post
1519    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1520      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1521    o fix the pickup behavior for obcs in combination with ptracers
1522    o fix a bug in ptracers_external_fields_load
1523    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1524      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1525    o transfered surface NH pressure to eta field (if exactConserv).
1526    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1527         and update lab_sea output.txt file.
1528    o completing 3-dim. relaxation code: additional term
1529         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1530      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1531      * At compile time, in "EXF_OPTIONS.h" set
1532          #define  ALLOW_CLIMTEMP_RELAXATION
1533          #define  ALLOW_CLIMSALT_RELAXATION
1534      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1535          tauThetaClimRelax3Dim = 15552000.0,
1536          tauSaltClimRelax3Dim  = 15552000.0,
1537      * 3 cases:
1538          1) Use a constant-in-time 3-dim. field
1539          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1540          3) Real-time relax. to time-evolving prescribed field
1541    o Adding Laplacian-type smoothness constraint on
1542      initial and boundary (forcing) controls (ic, bc)
1543      * enable at compile-time via
1544        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1545      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1546      * Absolute scale somewhat unclear so far
1547      * no area weighting was included since no other cost term does so far
1548    
1549    checkpoint57y_post
1550    First step for a NLFS adjoint
1551    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1552    o new init. routines for calc_r_star, calc_surf_dr
1553    o still need to deal with ini_masks_etc
1554    o testreport seemed happy
1555    checkpoint57y_pre
1556    
1557    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1558    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1559    o add new offset feature to offline pkg (plus minor cleanup)
1560    o cfc fixes for final year of integration
1561    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1562      be in GCHEM_OPTIONS).
1563    
1564    checkpoint57x_post
1565    o fix testreport Pb in multiple test experiment.
1566    o cleanup our namelist syntax in verification:
1567      - make it more F95 standards compliant (some work still needed)
1568      - allows the vast majority of our tests to work with gfortran
1569    o Non-Hydrostatic:
1570     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1571     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1572    o Allow to apply AB on T,S rather than on AB(gT,gS):
1573     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1574     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1575       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1576     - need a "clever" read_pickup to restart from the other AB formulation
1577    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1578    o remove some unused variables (reduces number of compiler warnings)
1579    o adjoint
1580      * Disable useVariableViscosity for adjoint for time being
1581        (there are a number of extensive recomputations)
1582      * Initialize certain variables needed for adjoint
1583    
1584    checkpoint57w_post
1585    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1586                 fix the singleCpuIO RS version of MDSWRITEFIELD
1587       and add a WARNING if using globalFiles=T with multi-processors.
1588    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1589      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1590    o tracer advection scheme:
1591      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1592       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1593       was not very convenient).
1594      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1595       (further tests needed for the implicit DST & Flux-Limiter schemes).
1596    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1597      and sRef for convenience, handy, when you want to initialize
1598      ptracers in a large domain with a constant non-zero value. Also,
1599      untangle ptracers_init.F a little.
1600    
1601    checkpoint57v_post
1602    o change dome exp. to use variable viscosity in side-drag terms.
1603    o remove all the files from the cfc_offline test since they are now
1604      incorporated into tutorial_cfc_offline which has been producing
1605      identical results for a few days of testing
1606    o add new parameter: sideDragFactor to enable half-slip-side BC
1607      and change side-drag S/R to use viscosity from mom_calc_visc
1608      (can switch back by setting sideDragFactor=0.); affects results at
1609      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1610       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1611    o vorticity & strain are now computed without masking, to account for
1612      no-slip-side BC in variable viscosity calculation ; mask is applied
1613      anyway later on, before computing advection/coriolis terms.
1614    o modify exp4 to test new obcs support for reading from external files
1615      and for passive tracers
1616    o fix behavior of ptracers_monitor when monitor output is written to a
1617      netcdf-file; still not independent of monitor.F (writes in the same
1618      file).
1619    o change default value of tRef (put a uniform, meaningful value for ocean
1620      & atmos) and initialize sRef (was missing, as Martin mentioned).
1621    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1622      to be proportional to enstrophy dissipation length.  Thus,
1623       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1624      This is now consistent with Smagorinsky and with the manual.
1625    
1626    checkpoint57u_post
1627    o OBCS and PTRACERS: add open boundary support for passive tracers
1628      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1629        OB-values from file; this is not different from the way theta and salinity
1630        are treated
1631      - however, Orlanski-radiation conditions are not supported, and the model
1632        will stop if you use pTracers and Orlanski at the same time.
1633      - beefed up the rountine obcs_external_fields_load: now only those open
1634        boundary values are overwritten with values from files for which there
1635        are really files, otherwise the OB-fields remain untouched. This makes
1636        it possible to use different OBs at different ends of the domain (as
1637        with EXF)
1638    o reduce number of exch calls in shap_filt (s2).
1639    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1640      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1641    
1642    checkpoint57t_post
1643    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1644    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1645      same truncation, independent of the face number: affects affects several
1646      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1647    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1648      note that biharmonic viscosity + no-slip was not tested in any experiment.
1649    o fix bug in non-linear free-surf side-drag ; generate new output for
1650      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1651    o make mnc honor the writeBinaryPrec flag for most kinds of output
1652    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1653    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1654      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1655    o add brackets in multi-terms sum to get same truncation, independent of
1656      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1657      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1658    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1659      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1660      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1661      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1662      Suggested values of viscosity parameters found in mom_calc_visc.
1663      Many new viscosity diagnostics available.
1664    
1665    checkpoint57s_post
1666    o Add clearing-house for viscosity calculations, mom_calc_visc and
1667      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1668      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1669      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1670      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1671      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1672      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1673      ViscAhStrain and viscAhTension are now retired.
1674    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1675    o In response to JMC's bug report, genmake2 now ignores any soft-links
1676      that it finds in the *current* directory when searching for files.
1677      Soft-links found in any other source directories will still work as
1678      they did before.
1679    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1680      a C routine to unlimit the stack size
1681    o mnc-ify pkg/aim snapshot vars
1682    o mnc-ify pkg/land as requested by Daniel
1683    o various changes to mnc including:
1684      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1685      - output can now be grouped so that all files within a group
1686          change the ITER portion of their names in lock-step together
1687      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1688          and works with both EXCH1 and EXCH2 (but needs more testing)
1689      - writing works for all verification test cases w/ g77 on Linux
1690    
1691    checkpoint57r_post
1692    o make MNC variable initialization happen earlier
1693    o add diagnostics for (almost) each term of the momentum Eq.
1694    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1695    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1696    o remove MINIMAL_TAVE_OUTPUT option ;
1697      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1698    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1699      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1700    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1701    o add time-dependent SST, SSS control
1702    o cost terms in ecco/ modularized (new cost_generic.F)
1703    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1704    o new infrastructure for seaice model vs. obs misfits in seaice/
1705      * driver from the_main_loop.F is seaice_cost_driver.F
1706      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1707      * gradient check in Exp. 6a of natl_box_adjoint/
1708    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1709      (see README file)
1710    
1711    checkpoint57q_post
1712    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1713    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1714      - bug was reported by Jean-Michel and Ian Fenty
1715    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1716      update exp. cpl_aim+ocn output.
1717    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1718      Needed for high-res. runs with large global files
1719      to be able to limit tapelev size
1720    o Changed some tests for adjoint:
1721      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1722      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1723      * global_ocean.90x40x15/ back to default 3-level checkpointing
1724    o Modifications to enable scripted COMMON to MODULE conversion
1725      * verification/OpenAD/code/ has necessary scripts and description;
1726      * converts, compiles and runs successfully;
1727    
1728    checkpoint57p_post
1729    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1730    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1731      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1732    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1733    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1734      (was already the case for dissipation with mom_vecinv,
1735       and also the case for grad.PhiHyd when staggered-timeStep)
1736      This will allow to put dissipation out-off the AB time-stepping.
1737     Unfortunately, affects truncation error. Update output of exp. that "fails"
1738      (cg2d matching number) and leave the others for later: front_relax(10),
1739      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1740      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1741    
1742    checkpoint57o_post
1743    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1744      (2) its ready to be documented during the 20050801 DocFest
1745    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1746      for ideal_2D_oce and lab_sea on linux_ia32_g77
1747    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1748      in global1x1_tot/code_seaice_adj to access indices 32, 33
1749      (worth another tag)
1750    
1751    checkpoint57n_post
1752    o adding precip control xx_precip 32
1753    o adding swflux control xx_swflux 33
1754    o Replacing 10 forcing penalty cost routines by 1 generic.
1755    o Implementing partitioning in time-mean and variable adjustment
1756      for atmos. state.
1757    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1758    o in natl_box_adjoint:
1759      * updated exp 1 to 10
1760        (but does not have time-mean vs. variable split results yet)
1761    o updated global1x1/*_seaice_adj/
1762      to incorporate latest changes
1763    o enable useSingleCpuIO for mdsio vector routines
1764      (applies in particular to tapelev I/O)
1765    o removed inefficient K-loop in all active_file*control*.F
1766    
1767    checkpoint57m_post
1768    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
1769      and advect_cs (use EXCH-2 and standard cs-32 grid files).
1770    o pkg/exch2: filling of face-corner halo regions is optional
1771      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
1772    
1773    checkpoint57l_post
1774     tag before updating tutorials (pre-release-2)
1775    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
1776       for output and interpolation of input fields onto model grid)
1777    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
1778       Affects results of exp. rotating_tank ; update output.txt.
1779    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
1780          and taking the square quantity and/or using a fraction-weight field.
1781    o fix aim_diagnostics_init.F mate numbers.
1782    o add mnc output capability to diagnostics/diagstat and update
1783      our cvsignore files for the ACSII output generated
1784    
1785    checkpoint57k_post
1786    o lab_sea now uses diagnostics package and provides a suite of
1787      new EXF diagnostics output.
1788    
1789    checkpoint57j_post
1790    o exf
1791      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1792        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1793        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1794      * extended diagnostics output
1795        - now includes all EXF variables
1796        - hs, hl moved to common block
1797        - separate S/R for diagnostics, called after ctrl vector is added
1798        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1799        - EXFqnet contains true Qnet (i.e. includes qsw)
1800      * updated verif. lab_sea, global_with_exf
1801      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1802        to ensure that diagnostics sees a true EXFqnet
1803    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1804    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1805      several times with different frequencies.
1806    o mnc-ify the thsice package as requested by Daniel Enderton
1807      - the monitor--MNC output needs work
1808      - many attributes need to be added (most are currently blank)
1809    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1810      - many attributes need to be added (most are currently blank)
1811    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
1812    o add Sadourny like discretization to the 4th.O vorticity advection scheme
1813    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
1814      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
1815         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
1816    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
1817     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
1818    
1819    checkpoint57i_post
1820    o Diagnostics package was changed: diagnostic allocation is now deactivated
1821      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1822    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1823      add 1rst Order upwind vertical Shear.
1824    o add a quick fix for A/B checkpointing in OFFLINE mode
1825    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1826      end-run around the C/Fortran linking horror in eesup/src/timers.F
1827    o added pkg/runclock: allows user to terminate run based on wall clock
1828    o added non-hydrostatic scaling parameter: nh_am2
1829    o pkg/my82: futile attempt to make results compiler-independent by adding
1830      some "_d 0", etc. no effect.
1831    o for mnc output, fill the 'T' coordinate var with myTime and create a
1832      separate 'iter' variable for iteration count
1833    o pkg/diagnostics:
1834      add new capability: output of Global/Regional & per-level statistics ;
1835      tested against monitor output (including land & thSIce) on various exp.
1836    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1837    
1838    checkpoint57h_done
1839      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1840      data.diagnostics, data.gchem, data.ptracers) is done.
1841    
1842    o pkg/diagnostics: prepare for Global/Regional statistics.
1843      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1844    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1845      and rename it: DIFFERENT_MULTIPLE
1846    
1847    checkpoint57h_post
1848    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1849    o pkg/diagnostics: change output frequency, now in seconds (instead
1850      of Nb of iterations). This requires to change data.diagnostics.
1851    checkpoint57h_pre
1852    
1853    o in mnc, let the user create the output dir if both mnc_outdir_date
1854      and mnc_outdir_num are false
1855    o add fflags() to pkg/diagnostics which allows one to specify, on a
1856      per-file basis, the file precision [default behavior is unchanged]
1857    o added diagnostics to pkg/kpp, including computation of mixed layer
1858      depth based on a temperature/density criterion
1859    o updated verification/natl_box to test the new pkg/kpp diagnostics
1860    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1861    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1862    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1863      not mnc -- this mistake was found by JMC and is now corrected
1864    
1865    checkpoint57g_post
1866    o add Adams-Bashforth 3rd Order time stepping:
1867      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1868      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1869    checkpoint57g_pre
1870    
1871    o make lambda[Theta,Salt]ClimRelax spatially varying
1872      (default remains spatially uniform constant based on tau)
1873    o added new control variables
1874      * init. uVel, vVel, etanN
1875      * lambda[Theta,Salt]ClimRelax
1876    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1877      (suggested by G. Forget)
1878    
1879    checkpoint57f_post
1880    o add parameter "baseTime" = model base time = time at iteration zero
1881      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1882      account for baseTime shift
1883    o move Coriolis arrays from PARAMS.h to GRID.h
1884    checkpoint57f_pre
1885    
1886    o mnc-ifying the seaice package
1887    o introduced an alternative length scale calculation for use in the limiting
1888      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1889    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1890    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1891      as well as grad(vort3).  Made it compatible with both approximate form
1892      for the cubed sphere and full form of these gradients.  Added flag
1893      useFullLeith to select between approximate and full form.  
1894    o add "d0" in getcon.F to reduce differences between compilers/platforms
1895      update output.txt of exp. fizhi-gridalt-hs
1896    o change port_rand funtion to allow to set the seed.
1897    o fix obscure MNC bug involving conversion between reals and integers
1898      - it caused no problems with certain (eg. gcc, ifc) compilers but the
1899        new version is now more standards-compliant
1900    o adjoint-related modifications
1901      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
1902      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
1903      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
1904    
1905    checkpoint57e_post
1906    o Adding eddy stress controls a la Ferreira et al.
1907    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
1908    
1909    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
1910      update output.txt of exp. fizhi-gridalt-hs
1911    o add more "Z" dimensions and associated coordinate vars to MNC
1912    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
1913    o parameter calendarDumps: when set, approximate months (30-31 days) and years
1914      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
1915      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
1916      months and years.  Requires pkg/cal.
1917    o diagnostics: add pickup functionality
1918      - off by default for backwards compatibility
1919      - current version only uses MDSIO -- MNC will be added
1920    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
1921    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
1922    
1923    checkpoint57d_post
1924    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1925    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1926      output from the diagnostics package
1927    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1928    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1929      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1930    o add coordinate variables to the MNC output from the diagnostics package
1931    o change MNC-flags default value: true when useMNC=TRUE
1932    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1933      the ability (off by default) to read the grid information using MNC
1934    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1935    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1936    o do snap-shot diagnostics at the middle of the time-interval (instead of
1937      at the end).
1938    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1939      new test for AIM with thSIce + slab-ocean
1940    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1941    o move state variable diagnostics to the beginning of the time step ;
1942      (note: still needs some work specially for snap-shot diagnostics)
1943      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1944    
1945    checkpoint57c_post
1946    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1947    o generate new output.txt files on faulks with g77 & the new -ieee option
1948    checkpoint57c_pre
1949    
1950    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1951      update output.txt of exp. global_ocean.90x40x15
1952    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1953      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1954    o add saltFlux(+File) forcing capability with periodicExternalForcing
1955    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1956    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1957    o improvements for the MNC output from DIAGNOSTICS:
1958      - correct handling of the unlimitied dimension
1959      - all dims now have associated coordinate variables
1960      - variables located at U, V, and Corner ("Z") points are now written
1961        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1962        *all* data points are output
1963    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1964    o added pkg/seaice/seaice_monitor.F
1965    o mdsio_readfield.F can now read files visible only to master MPI process.
1966    o pkg/seaice: some test code for ice-modified ocean stress
1967    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1968      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1969      spurious negative numbers for precipitation and humidity.  Will cause
1970      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1971    o pkg/ctrl/
1972      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1973        May be enabled via doPackDiag
1974      *  introduce z-scaling of
1975         + gradient (doZscalePack) and
1976         + control (doZscaleUnpack)
1977    o pkg/mdsio/
1978      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1979      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1980    
1981    checkpoint57b_post
1982    o simplify options in diagnostics_fill arguments (remove weird combinations)
1983    o fix MNC coordinate variables so that they now contain per-face index
1984      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1985      general, EXCH2 grids are only aligned to a "local" coordinate system
1986    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1987    o Implement instantaneous output within pkg diagnostics:
1988      setting a negative frequency in data.diagnostics produces
1989     "snap-shot" output (as opposed to time-average if freq > 0)
1990    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1991      NOTE: change ptracer diagnostics name: use 2 characters to work with
1992            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1993    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1994      becomes the coordinate variable for the 'T' dimension
1995    o add CF-style coordinate variables to MNC
1996      - just a first cut:  numbers are meaningless on the cubesphere and
1997        missing along the T axis but otherwise it works!
1998    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
1999    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
2000    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
2001      this is based directly on what the model compute, so that the content of
2002      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
2003    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
2004    o clean up build options files for SunOS, in particular
2005      - remove -traditional from xmakedepend
2006      - change -xarch=v9 to -xarch=native for f77
2007      - restore use of make (not gmake)
2008      - add CC=gcc if using g77
2009    o changes per discussion of AM, JMC, & EH3 today:
2010      - move redundant "grid" variables out of "state" -- in preparation of
2011        creating proper CF-style coordinate variables and in recognition
2012        that any/all grid variables can be easily copied (eg. w/NCO) from
2013        the grid files into any of the other NetCDF files
2014      - *always* output grid variables with MDSIO (this will eventually be
2015        changed)
2016      - output MNC grid file if useMNC is true
2017    o every instance of _END_MASTER() has been found and replaced with
2018      _END_MASTER( myThid ) in order to satisfy certain picky Sun
2019      preprocessors
2020    o re-arrange diagnostics pkg initialisation:
2021     - allow each package to extend the available diagnostics list
2022     - add some checking and fix small problems (multi-threaded, ...)
2023     - new S/R diagnostics_fill (replace fill_diagnostics):
2024       look through the short list of active diag. (instead of the long list)
2025       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
2026    
2027    checkpoint57a_post
2028    o this set of changes restores TAMC compatibility
2029      tested for global_ocean.90x40x15 adjoint on trough
2030      (what a pain)
2031    
2032    checkpoint57a_pre
2033    o some modifs in tools/build_options for sunos
2034    o call ctrl_pack for ctrl at end for optimcycle=0
2035    
2036    checkpoint57
2037    o add horizontal bi-harmonic viscosity for vertical velocity
2038      - new parameter viscA4W (defaults to viscA4)
2039      - affects only non-hydrostatic code
2040      - to be done: no-slip lateral boundary conditions
2041    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
2042    o implement Implicit Vertical advection for pTracers
2043    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
2044      (implemented also for implicit vertical diffusion & advection)
2045    o OBCS: extend application of tracer open boundary conditions
2046      to a strip beyond the boundary of width Olx/Oly
2047    o add call monitor to TAF set of required calls (flow directives)
2048      and include in natl_box_adjoint
2049    o untangle a few ifdefs related to cost, ctrl, autodiff
2050      untangel a few ALLOW_ECCO_OPTIMIZATION
2051    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
2052      (theta2, salt2 in ecco_cost_weights)
2053    
2054    checkpoint56c_post
2055    o OBCS as control variables
2056      - update ctrl_ad_diff.list, obcs_ad_diff.list
2057      - remove balance of obcs controls from default
2058      - fix index bug nobcs in ctrl_init
2059      - fix dummy fields filen in ctrl_pack
2060      - add dummy weights for obcs
2061    o lsopt: comment out fort.94 output
2062    o optim:
2063      - remove unnecessary header files
2064      - adjusted namelists
2065      - add xerbla.F to Makefile
2066    o exf:
2067      - multiple modifications of exf_check_range
2068      - unit change in exf_init_runoff from [m/year] to [m/s]
2069    o mdsio:
2070      - i/o-vector change debugLevel from debLevA to debLevB
2071    
2072    checkpoint56b_post
2073    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
2074      is called from DO_THE_MODEL_IO
2075      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
2076      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
2077      - clean up PTRACERS_WRITE_TIMEAVE a little
2078    o add another verification experiment that tests both the cfc-pkg and
2079      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
2080      reactive tendencies treated inline with regular timestepping
2081    o testreport previously did a lousy job of comparing small numbers, so
2082      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
2083      implemented in the little c-progam tmp_cmpnum.c which is embedded in
2084      testreport.
2085    o ptracers_monitor: bug fix for MPI
2086    
2087    checkpoint56a_post
2088    o GCHEM: finish reorganizating the package
2089      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
2090        (introduces another 3D-array for each passive tracer, but only if
2091        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
2092        gchemTendency is not needed because the timestep is done separately)
2093      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
2094      - GCHEM is now---more or less cleanly---separate from PTRACERS
2095      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
2096        so clear to me how that should be done in a general way.
2097    o CFC: improve formatting of output in CFC_ATMOS
2098    o PTRACERS:
2099      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
2100        that ALL experiments with ptracers enable can be checked. This makes
2101        GCHEM_MONITOR obsolete.
2102      - include a runtime parameter PTRACERS_monitorFreq that defaults to
2103        monitorFreq
2104      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
2105    o add PTRACERS (PTR0[1-5]) to testreport output
2106    o exf_check_range:
2107      * default changed to .TRUE.
2108      * will check values for niter0 if debLevA, every timestep if debLevB
2109      * STOP in exf_check_range if 'out of range'
2110      * range chosen generous to allow for potential extema
2111      TBD: a version with stricter range
2112           permitted range would be runtime parameters
2113  o GMredi:  o GMredi:
2114    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
2115    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.

2120    - introduced a useGCHEM runtime flag and applied it everywhere.    - introduced a useGCHEM runtime flag and applied it everywhere.
2121      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
2122        this flag is now only visible within GCHEM-pkg routines.
2123      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
2124        be replaced by a 3D array that is computed before thermodynamics; for
2125        this, the tracer ID iTracer had to be included into the parameter list
2126        of ptracers_forcing
2127      - set up forward_step to call gchem_forcing, that will replace
2128        gchem_forcing_int in ptracers_forcing
2129      - cleaning up
2130  o small cleaning of exch2: remove files that are also in eesupp/src  o small cleaning of exch2: remove files that are also in eesupp/src
