7    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
8      real fresh water flux (not yet)
9    o pkg/mdsio & rw:
10     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
11     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
12    o pkg/flt:
13     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
14       init_fixed & ini_varia.
15     - clean-up & simplify linear interpolation S/R:
16       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
17     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
18     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
19     - add vert. coordinate & horiz. indices to output files.
20     - change vertical position in initial condition, from index to depth [m].
21    o pkg/ggl90: a few modifications:
22     - fix bottom boundary condition, and interpolation of KappaE
23       near top and bottom
24     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
25     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
26     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
27    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
28      (maintain temporary backward compatibility, until next checkpoint)
29    
30    checkpoint61h
31    o pkg/diagnostics with "periodic averaging diagnostics":
32      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
33    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
34    o pkg/obcs: fix loop ranges for balancing code
35    o pkg/flt:
36     - improve criteria for finding which tile owns a float.
37     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
38    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
39      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
40      with ocean biogeo)
41    o pkg/flt:
42     - do some cleaning and fix the restart ;
43     - add output.txt in flt_example/results to get this pkg tested.
44    o genmake2: add an EXTENDED_SRC option and flag.
45       for now, cannot be turned on on command line (only through genmake_local)
46    o pkg/mdsio: read/write vector:
47     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
48     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
49       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
50     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
51      (drop to 4 digits matching for grad). But this test does not look very
52      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
53    
54    checkpoint61g
55    o pkg/flt:
56      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
57       + make OPTIONS file more standard.
58      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
59      - fix _BYTESWAPIO CPP-Flag
60      - standard reading of file-parameter "data.flt"
61      - fix argument list of S/R FLT_RESTART
62      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
63    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
64    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
65      a still unfixed compiler/optimization bug
66    
67    checkpoint61f
68    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
69      update results of global_ocean.cs32x15.icedyn test.
70    o move getcon.F from model/src to pkg/fizhi.
71    o pkg/exf: add parameter for extrapolation of temp up to the surface
72       and option to prevent negative evap (in bulk_largeyeager04 only).
73    o Prather Advection scheme: fix tracer conservation for divergent flow
74      (e.g., when using NonLin Free-Surface).
75    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
76    o gmredi (Visbeck-variable-K):
77     - add more parameters to Visbeck-variable-K.
78     - use a 5 points average for dSigmaR in Visbeck-K calculation
79       (more "homogenous": same stencil and same weights as in dSigmaH)
80     - update output of ideal_2D_oce experiment.
81    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
82      (#undef REAL4_IS_SLOW)
83     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
84       coordinate variable
85     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
86       (surface forcing fields), removes some of the functionality
87     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
88     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
89       probably not all: copy _RS surface flux fields to RL field before
90       calling DIAGNOSTICS_FILL
91     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
92       real*4 (CALL EXCH_*_RS) versions.
93     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
94       (generate new output).
95    
96    checkpoint61e
97    o gmredi (Visbeck-variable-K):
98      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
99      - change computation of Visbeck-K where Slope > Smax :        
100        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
101        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
102    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
103      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
104    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
105    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
106      does not become too large (to avoid precision problems in implicit-diffusion
107      solver); update ideal_2D_oce output.
108    o pkg ggl90:
109      - in ggl90_cal.F: compute only one set of visc/diff, used to
110        step forward TKE/T/S/momentum
111      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
112        have Prandlt =1)
113    o gmredi (fm07):
114      - add lower limit on Transition layer thickness + lower limit on 1/lambda
115      - allow to set few more params from data.gmredi
116    o pkg ggl90:
117          - add missing sqrt(2) factor in computation of mixing length
118            scale in ggl90_calc.F
119            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
120    
121    checkpoint61d
122    o adjoint modifs
123      - adapt to new field rhoInSitu
124      - allow to revert from StoreDynVars2D, StoreDynVars3D
125        to individual fields
126        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
127    o store 3-D (in-situ) density in commom block (DYNVARS.h)
128     - save 1 rho computation.
129     - no longer modify T & S inland when using down_slope pkg.
130    o gad_som : allow to switch to SOM advection for T & S without corresponding
131      pickup files (using new S/R: MDS_CHECK4FILE).
132    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
133      (for useSingleCpuIO to work in multi-threaded)
134    o pkg/shelfice:
135     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
136       with SHELFICEtopoFile in data.shelfice
137     - move code for reading ice shelf topography and modifying hFacC into separate
138       subroutines of the shelfice package
139     - separate initialisation of "fixed" and "variable" variables
140     - kTopC is not (yet) replaced by kSurfC, although this is possible
141    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
142    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
143      and rename:
144      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
145      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
146    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
147    
148    checkpoint61c
149    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
150      to add mass source/sink of fluid in the interior (3-D generalisation
151      of oceanic real-fresh water flux).
152    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
153    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
154    o new pkg: down_slope
155      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
156      - presently, modify T & S inland (dwnslp_calc_rho.F).
157        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
158      - implementation for ocean in P-coords not tested.
159      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
160    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
161      (to facilitate conversion of oceanic pkg to p-coordinate).
162    o change FIND_RHO to FIND_RHO_2D :
163      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
164    o new pkg: cheapaml
165    
166    checkpoint61b
167    o exch2:
168      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
169      - no longer depend on the order sequence (N,S,E,W).
170      - 3rd exchange no longer needed (tested with 24 tiles).
171      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
172      - exch_UV_A-grid readily available (but not yet tested).
173      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
174      (both are no longer needed) in exch_uv: no effect in forward run; but
175       get truncation error differences with adjoint exch.
176    o exch2:
177     - change index-bounds storage (moved from target to local tile,
178       more intuitive this way) ; rename/remove some variables.
179     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
180    
181    checkpoint61a
182    o exch2/matlab-topology-generator:
183      fix bug in index bounds for N-S internal exchange (hard to tell if this
184      had any effect on the solution).
185    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
186      is exceeded
187    o testreport: modify syntax of awk, so that it works also with
188      awk, and not only with nawk and gawk
189    
190    checkpoint61
191    o autodiff
192      Change default for TAF usage by removing argument '-nonew_arg'
193      This changes TAF subroutine argument list (ordering of active var.)
194      Omission of this flag leads to incompatibility w.r.t. TAMC
195      To restore TAMC-compatibility, need following modifs:
196      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
197      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
198      Tested TAF version is 1.9.22
199      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
200    
201    checkpoint60
202    --->>> This is the last checkpoint for which generating the adjoint
203    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
204    --->>> by default.
205    --->>> Future checkpoints will ommit this flag by default.
206    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
207    o pkg/grdchk: Add gradient check to etan0 perturbations.
208    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
209    o pkg/autodiff: more flexibility in zeroadj.
210      model/src: modifying do_oceanic_phys.F accordingly.
211    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
212    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
213      special setup of gmredi for which the adjoint is stable
214      enough for parameter optimization.
215    o bridging the gap between eddy stress and GM.
216      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
217          along with a change in CPP option (now ALLOW_EDDYPSI).
218      -> when using GM w/ GM_AdvForm:
219          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
220          is applied either in the tracer Eq. or in momentum Eq.
221          depending on data.gmredi (intro. GM_InMomAsStress).
222      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
223      The key modifications are in model/src/taueddy_external_forcing.F
224      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
225    
226    checkpoint59r
227    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
228      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
229      fix option to read coriolis(@ cell-corner) from files with CS-grid.
230    o pkg/mnc: add some attributes to standard 1D-coordinate variables
231    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
232      mass points, when using mnc for output
233      - add runtime parameter (missing_value, missing_value_int) to override
234        default (which is the value of getcon('UNDEF'))
235    o pkg/mnc: prepare mnc for the actual use of missing values with the
236      diagnostics package: small fix in mnc_cw_readwrite.template and more
237      initialisation of never used fields
238      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
239      versions
240    o pkg/thsice/thsice_ini_vars.F added default initial values so that
241      thermodynamics sea ice solver does not blow up when some initial fields
242      are missing.
243    o move from external_forcing_surf.F to ini_forcing.F
244      the p-coord. hack consisting in using pLoad to set phi0surf ;
245      update output of tutorial_global_oce_in_p (affected @ truncation level).
246    o Freshen up a bit hs94.1x64x5, notably:
247      remove rotationPeriod and tRef=5*0. (adjoint only), and add
248      exactConserv=.TRUE.
249    o pkg/generic_advdiff:
250      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
251      applies to files where Temperature & Salinity 2nd Order moments are used.
252    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
253      this uses a dynamically allocated internal state data structure
254      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
255      and requires a fortran 90 compiler
256    
257    checkpoint59q
258    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
259       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
260    o Refresh tutorial_global_oce_biogeo, notably:
261      - change bathymetry (put back seamounts in ACC, use hFacs)
262      - change EOS (POLY3 --> JMD95Z)
263      - use Bryan-Lewis vertical diffusivity
264      - use multidimensional advection
265      - remove old virtual virtual in dic pkg, now done through ptracer pkg
266      - change a couple of parameters in dic pkg
267    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
268    o pkg/obcs: change default to OBCSfixTopo = .true.,
269      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
270      - replace "debugMode" with "debugLevel .GE. debLevB"
271    o implementation of TAF directives for gchem,cfc,dic
272    o remove "exp5" (replaced by tutorial_deep_convection).
273    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
274      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
275      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
276      --> changes results in exp4, seaice_obcs
277    o tutorial_deep_convection :
278      update the set-up and increase resolution and domain size ; start
279      from pseudo initial conditions = output at t=120mn in order to see
280      something happening when running testreport.
281    o pkg/seaice: add os7mp as an advection scheme
282                  add check for advection schemes
283                  add a flag for restoring T and S underneath sea ice
284    o pkg/my82: add netcdf-support and diagnostics
285    o thsice pkg:
286      - Now hsMax limits snow height by turning it into ice following
287        flooding scheme (and now conserving energy)
288      - Slight rewriting of the formula in thsice_calc_thick.F
289      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
290      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
291    
292    checkpoint59p
293    o gchem / dic / cfc :
294      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
295      - add new parameter files: "data.dic" & "data.cfc" ;
296      - various re-arrangement in initialisation & header file ;
297      - fix tutorial_global_oce_biogeo for multi-threaded test.
298    o pkg/dic: test for "pickup_dic" file when restarting ;
299      if no pickup-file, can restart with a re-initialised pH (same as it did
300      before) providing pickupStrictlyMatch is set to False.
301    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
302      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
303    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
304      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
305    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
306     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
307       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
308    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
309       scheme to use for vorticty-term ;
310     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
311       (with default selectVortScheme, return to original discretisation)
312     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
313    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
314    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
315      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
316      also fix diagnostics VISCAHW & VISCA4W.
317    
318    checkpoint59o
319    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
320    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
321      move a few statemens out the main loop into separate loops
322    o pkg/shelfice:
323      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
324        (kg/m^2/s), does not break tests, because in verification/isomip,
325        rhoConstFresh=rhoConst (by accident)
326      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
327      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
328        new file model/src/seawater.F, so that they are available for all pkgs.
329      - convert potential temperature into in-situ temperature. This changes the
330        isomip tests => update tests
331    o add a flag writePickupAtEnd (default=true) to be able to suppress
332      writing a pickup at the last timestep
333    o tools/mpack-1.6 :
334      - disable automake (not working) and autoconf (not needed).
335      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
336        also cleaner with much less compilation warnings.
337    o pkg/profiles:
338      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
339      (for "less than 32 characters name" compiler requirement)
340    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
341      conditions that have a different sampling frequency than S/T/U/V obcs
342    o pkg/diagnostics (stats-diags):
343      - fix global Min/Max in case 1 processor get only empty tiles
344    o genmake2: replace (4 times)
345         make genmake_tc_1.o >> genmake_warnings 2>&1
346      with
347         COMM="$CC $CFLAGS -c genmake_tc_1.c"
348         echo $COMM >> genmake_warnings
349         $COMM >> genmake_warnings 2>&1
350      to make genmake2 always see the value of CC as specified in the optfile.
351    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
352      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
353      - modify verification advect_cs test to test SOM-advection on CS-grid.
354    o pkg/ctrl:
355      - Rewrite of ctrl_map_ini_ecco.F,
356        introducing a generic routine (ctrl_map_ini_gen.F).
357      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
358    
359    checkpoint59n
360    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
361      number in dedicate array "hdiag":
362      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
363        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
364      - many small changes (integer format) for large number of diagnostics
365      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
366        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
367    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
368      usingSphericalGrid, this allows to define the rotated grid coordinates
369      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
370      geographical coordinates according to the inverse of the rotation defined
371      by the Euler angles, so that Coriolis parameter and online-interpolation by
372      exf works with the geographical coordinates on XC/YC/XG/YG.
373      Naturally, this feature does not work with all packages, so some
374      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
375      profiles), because there the coordinates are assumed to be regular
376      spherical grid coordinates.
377    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
378      - introduce isopycnal diffusion coefficient control.
379    o tools/adjoint_options:
380      - additional control vector components.
381    o pkg/mnc: have mnc create marginally meaning full coordinate variables
382      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
383    o pkg/mypackage:
384      - add example of read/write pickup for state-var ;
385      - add entry points to the main code for state-vars diags & write-pickup.
386    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
387      transitions for useExfYearlyFields
388      - add new subroutine that determines the file to read from for
389        use*YearlyFields = .TRUE. and .FALSE.
390      - add a verification experiment to global_with_exf that tests
391        useExfYearlyFields with USE_EXF_INTERPOLATION defined
392    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
393      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
394      subroutines (which could be generated from a template, because they are
395      almost identical), for now they are included in obcs_prescribe_read.F for
396      simplicity
397    o pkg/exf:
398      - add a little more diagnostic to exf_interp_read (in analogy to
399        mds_read_field, can be turned off with debugLevel < debugLevA=1)
400      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
401        ugly but fast by unrolling short inner loops, inserting a unroll=8
402        directive in routine lagran, and splitting a loop and making do while the
403        outermost loop (the latter requires the intoduction of index arrays)
404    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
405    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
406      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
407    o verification/seaice_obcs: updated for restart test and latest options
408    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
409      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
410      for now this is only available for the C-grid code and also within
411      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
412    
413    checkpoint59m
414    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
415      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
416    o gad_som : fix flux output (& diagnostics) to have same units as other  
417      advection scheme fluxes (was previously multiplied by deltaT).  
418    o added verification/seaice_obcs both to test seaice open boundaries
419      and to provide an example matlab scrpt for generating them
420    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
421    o pkg/salt_plume: clean up salt_plume_frac.F to
422      remove redundancy in PlumeMethod 1 and 4
423    o pkg/kpp: added saltplume diagnostics
424    o pkg/obcs and pkg/seaice:
425      - do not set uice and vice to zero when OB*icefile are unspecified
426      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
427      - moved seaice tracer obcs after call to seaice_growth
428    o pkg/salt_plume: added various options for salt plume depth
429      criterion and for vertical distribution of the salt
430    
431    checkpoint59l
432    o pkg/ptracers: new version of ptracers pickup:
433      read meta file and write only fields which are needed to restart.
434      ( same logic as main pickup file ; also using pickupStrictlyMatch )
435    o pkg/seaice:
436      - add timescale for melting due to warm mixed layer as a means of
437        setting SEAICE_availHeatFrac more conveniently
438      - add a CPP-flag/runtime parameter check for flooding algorithm
439      - reformulated availHeat in seaice_growth.F to be independent of AREA
440    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
441      unit changes
442    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
443    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
444      SX vector computer.
445    o pkg/seaice:
446      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
447        seaice forcing fields can now be read only through pkg/exf
448      - removed some unused halos
449    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
450    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
451      or U/VICE from U/VWIND before computing U/VSTRESS
452    
453    checkpoint59k
454    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
455      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
456    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
457      all experiments pass when compile with un-initialised var. checking option.
458    o added pkg/salt_plume
459    o script to test restart (for now, in MITgcm_contrib/jmc_script)
460    o pkg/seaice: new read/write pickup version.
461      read meta file and write only fields which are needed to restart.
462      ( same logic as main pickup file ; also using pickupStrictlyMatch )
463    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
464    o lab_sea.hb87: modify the domain & update output.hb87.txt :
465      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
466      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
467      process. Fixed here by closing the domain at the Northern boundary.
468    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
469    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
470      a set of consecutive levels in/from a 3-D array.
471    o pkg/ptracers:
472      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
473      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
474    
475    checkpoint59j
476    o in pkgs: dic, obcs, offline, rbcs:
477      standard way to compute coeff. for time interpolation between 2 time reccords
478      which retains full precision (& make results less dependent on compiler).
479      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
480    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
481      packages instead of reading ice cover and wind speed separately
482    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
483     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
484      to allow to compile customized code before the update)
485    o cleaning-up:
486      - fix CPP instruction syntax in pkg/obcs
487      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
488        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
489      - fix some threads issue in IO parts.
490    o pkg/dic:
491      - add tons of "_d 0" (--> much better testreports !)
492       and then update outputs of tutorial_global_oce_biogeo
493    o pkg/mom_fluxform:
494      add a special version of momentum advection intended to conserve momentum
495      next to a bathymetry step or a coastline edge. (default = off = #undef)
496    o new read/write pickup version:
497      - for now, only implemented for main (mdsio) pickup file.
498      - write out only what is needed to restart; merge pickup_nh , pickup_ph
499        and main pickup together.
500      - read meta file; read only what is needed to restart; stop if a field
501        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
502        if it make sense (even if the restart is not perfect).
503      - if no meta file, assume that pickup to read corresponds exactly to
504        a pickup that would currently be written.
505      - read pickup written in the old format (until checkpoint59i) if it
506        recognizes an old meta file (no field-list).
507      - add a meta file in exp. which starts from a pickup: 2 cases:
508        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
509         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
510        b) a meta file describing the content of the associated pickup file
511         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
512    o pkg/mdsio & pkg/rw:
513      - new routine to read a meta file ; new set of routine to read
514        Multiple-fields file (with meta file).
515    o added open boundary conditions capability for seaice
516        HSNOW, HSALT, UICE, and VICE
517    
518    checkpoint59i
519    o adjoint:
520      * fix multiDimAdvection adjoint
521        (partial recomputation problem by TAF for fVerT(:,:,kDown)
522        and comlev1 size definition (maxpass vs. max. number of tracers)
523      * verification/global_ocean.90x45x15 adjoint now tests
524        NLFS and multiDimAdvection using DST3 (=30)
525      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
526    o pkg/kpp: add "_d 0" to real constant (if missing);
527      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
528      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
529    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
530      for internal parameters related to restart process (formerly from PARAMS.h)
531      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
532    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
533      as argument. (only atm2d & obcs write_pickup have not yet been updated)
534    o pkg/monitor:
535      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
536      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
537      - account for deep Atmosphere factor and density factor (anelastic)
538    o added open boundary conditions capability for seaice HEFF and AREA
539    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
540      thermodynamics
541      - requires a little reorganization, which affects the testreport results
542        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
543        so that now the conservative form is tested
544      - add a few comments
545    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
546    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
547    o add new diagnostics to seaice: advective, diffusive fluxes (only for
548      multidim-advection, for scheme 2 they are not filled) and transports,
549      thermodynamic growth rates
550    o change units of EmPmR (inside the code, + within coupling interface)
551      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
552      Affects results @ truncation level (cg2d match) and update output of
553       experiments: lab_sea(6), global_ocean.90x40x15(10),
554      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
555      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
556      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
557      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
558    
559    checkpoint59h
560    o pkg/exf:
561      - improve vectorization by moving if-statement out of loops in
562        exf_mapfields, exf_radiation
563      - exf_bulkformulae.F: introduce 2D fields and vectorize code
564    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
565    o testreport:
566      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
567        monitor & update offline_exf_seaice exp. output.
568      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
569    o pkg/seaice:
570      - bug fix in the evp solver: boundary conditions were affected be
571        masking of zMax/zMin (changes results)
572      - minor bug fix in boundary conditions in seaice_calc_strainrates
573        (changes results for no_slip)
574      - seaice_lsr.F: make interpolation of eta dependent on boundaries
575      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
576      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
577        stress formulation and no-slip boundary conditions
578    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
579      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
580    o pkg/seaice: a first HSALT time stepping equation has been checked in
581    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
582      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
583      without requiring DO-IF statements
584    o pkg/thsice:
585      use continuous power-law function for partition of energy between lateral
586      melting/freezing and thinning/thickening ; old code using step function
587      still available with #undef THSICE_FRACEN_POWERLAW
588      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
589    o testreport: change AD testing : check against results/output_adm.txt
590      using same scripts as for forward test.
591    
592    checkpoint59g
593    o adjoint testing: in preparation for changing testreport:
594      - output format: cost and grad written on separated lines
595      - ad output results in directory "results" (instead of "results_ad")
596    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
597    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
598    o pkg/ecco: allow user defined cost function contributions
599    o testreport:
600      Allow to choose (per experiment) the list of tested output variables
601       and the main variable (used to issue a pass/FAIL ) ;
602      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
603      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
604      Also modify printing of summary:
605       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
606       b) echo the list of tested variables in the individual summary.txt of
607          each experiment.
608    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
609      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
610      (but still depend on the tile decompostion of the domain).
611    o pkg/seaice: change a discretization detail to make the B-grid code
612      "more symmetric". This change is likely to remove all "ridges/leads" that
613      where quasi-aligned with the grid in B-grid solutions. It may also be
614      the solution to the stress coupling issues with the B-grid.
615    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
616      remove .cvsignore from input dir. (since testreport no longer run here).
617    o pkg/thsice:
618     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
619     - fix reshaping of sea-ice just after advection:
620       melt all the ice only if ice-volume is too small.
621     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
622       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
623     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
624    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
625      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
626    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
627      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
628      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
629      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
630      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
631      -> update output.txt
632    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
633     this affects truncation error: -> update output.txt of exp:
634      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
635      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
636    
637    checkpoint59f
638    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
639    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
640      a bounded range (in forward mode)
641    o pkg/ecco, ctrl, autodiff and mom_common:
642     internal parameter controls, completements of implementations
643    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
644    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
645      (not seem any difference in testing results).
646    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
647       at face corners.
648    o pkg/generic_advdiff:
649     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
650      loop range indices for computing vertical advection tendency
651      and do the calculation in the interior only (no overlap) ;
652      for now, only implemented for SOM advection (to save CPU time).
653     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
654    o exch2 adjoint
655      First set of changes:
656      - add exch2 hand-written adjoint templates
657      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
658        This will require cleanup in pkg/autodiff/*.F
659        (changed routines currently kept separate in verif. code/)
660      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
661        that used to hide exch2 or cubed-sphere specific code
662        (commented via 'cph-exch2')
663    o pkg/seaice
664      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
665    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
666       output of global_ocean.cs32x15.thsice .
667    
668    checkpoint59e
669    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
670      for B-grid vector (not yet tested) and C-grid vector (<- only used
671      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
672    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
673      (#ifdef ALLOW_SALT_PLUME)
674    o gather_2d/scatter_2d: removed halo regions
675    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
676      scheme and the corresponding test case (under front_relax dir). For now,
677      only available with Skew-flux form and not yet tested in realistic set-up.
678      adjoint: store directives updated, but gradient checks deteriorated,
679      so maybe GM/Redi adjoint is now broken.
680    o seaice adjoint
681      * add AREA, HEFF, HSNOW as control variable
682        (should not change lab_sea results)
683      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
684    o pkg/seaice:
685      * added computation of saltFlux in seaice_growth;
686        For time being, sea ice salinity is assumed constant
687        contribution of snow flooding to freshening of sea ice is neglected.
688        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
689        defaults to 0.0 in order to maintain backward compatibility.
690        Typical values for SEAICE_salinity are 4 to 10 g/kg.
691      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
692      * added SEAICE_availHeatFrac, which specifies fraction of surface level
693        heat content used to melt or grow ice
694      * commented out cap of HICE: it helps keep ice thinner
695      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
696      * applied OBCS T/S mask to HEFFM sea ice mask
697    
698    checkpoint59d
699    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
700     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
701     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
702    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
703     and change default value of parameter "GM_Small_Number";
704     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
705       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
706       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
707    o pkg/ecco: cost function when applying pkg/smooth to controls
708    o pkg/ctrl: add forcingPrecond run time parameter
709    o pkg/seaice:
710     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
711     - fix bug in metric terms of u-equation in LSR solver (implicit part),
712       changes verification/lab_sea
713     - rearrange implicit part of u-equation in LSR solver to make it easier to
714       read, understand, and debug. This causes changes at the truncation level.
715     - fix (serious) bug in the boundary conditions (sign error in the implicit
716       part) of the LSR solver. Changes all LSR results.
717     - fixed problem with HSNOW initialization to avoid thick snow when AREA
718       is initilized with small values - does not change lab_sea results.
719     - added HsnowFile initialization capability
720    o pkg/smooth: addition to model/src and pkg/ctrl so allow
721     initialization of pkg/smooth and application to control vector
722    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
723    o dependencies: pkg/profiles requires pkg/cal
724    o pkg/profiles:
725     - added option ALLOW_PROFILES_GENERICGRID
726         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
727         that interpolation information (grid points and coefficients) is provided
728         within the netcdf input files.
729         -> sample matlab scripts can be found in MITgcm_contrib/gael
730         that allow you to prepare netcdf input files.
731     - also modified: cleaner include statements, cleaner error print statements,
732       cleaner stops when error, and more tests of the netcdf input files consistency.
733    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
734    o pkg/seaice:
735     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
736       requires a new routine: seaice_diagnostics_fill.F
737     - make sure that seaice does not move if not forced (pressure replacement
738       method, Hibler and Ip, 1995), changes results
739     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
740     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
741       It is turned off by default (=-1.), because it changes the results.
742     - make it possible to read AREA from a file, too.
743    
744    checkpoint59c
745    o add S/R and diagnostics for oceanic mixed-layer depth
746    o move GMRedi call after all vertical mixing schemes (including KPP)
747    o pkg/thsice:
748     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
749      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
750    o pkg/obcs:
751     - bug fix for balance code
752    o pkg/seaice:
753      - allow values of SEAICE_elasticParm > 1
754      - add new parameter SEAICE_evpTauRelax as an alternative
755        to SEAICE_elasticParm
756      - make lsr boundary conditions free slip (by default), changes result
757      - add code for no slip boundary conditions for lsr
758      - set minimum of zeta to zero (and not 4e8) (changes results)
759      - add a cap on AREA after advecting AREA if seaice_growth is not called
760    o change calculation of Visbeck K:
761      - no longer depend on tapering scheme; instead, compute slope (limited
762        by GM_maxSlope). this is equivalent to what was comuted before with
763        clipping or linear tappering.
764      - fix vertical averaging (wrong by 1/2 level)
765      - leave the old version (but will not be maintained) within
766        #ifdef OLD_VISBECK_CALC / #endif
767      - update output of exp. ideal_2D_oce
768    o change error catch in calc_r_star to improve vectorization
769    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
770      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
771    o adjoint:
772      Re-organized adjoint checkpointing according to Matt Mazloff
773      (but with modifs/completions/cleanups)
774      Storing is now bundled into large arrays to optimized I/O
775      (and second step in cleanup of the_main_loop)
776    
777    checkpoint59b
778    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
779      - export/import (between ocean & coupler) fields needed for ocean DIC.
780    o pkg/seaice:
781      - get rid of three more exchanges seaice_calc_viscosities (required
782        different loop boundaries in seaice_lsr and seaice_ocean_stress)
783      - bug fix in seaice_ocean_stress (update of lab_sea required)
784      - reduce loop boundaries to necessary minimum also in seaice_evp
785      - go back to the old way of computing deltaC/Z as the adjoint likes that
786        better
787    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
788      passive tracer to an Age Tracer) + update output.txt
789    o pkg/exf:
790      - implement A-grid / C-grid selection for wind-stress input files.
791      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
792      for now, in exf_bulk_largeyeager04.F only :
793      - change implementation for case where windspeed + 2. components wind-stress
794        are read-in. AND use rhoConstFresh to convert evap.
795    o pkg/seaice:
796      - use correct EXCH_UV for wind-forcing (on A-grid).
797      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
798        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
799    o pkg/exf:
800      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
801      EXF_INTERPOLATION:
802      - merge global_with_exf/code version of exf_interp_read.F
803        to the main code ;
804      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
805        reading the file ; Important: This options needs to be defined to recover
806        previous code.
807        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
808      - no longer loose real*8 precision along the way when using exf_iprec=64.
809    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
810      - change discretisation of evp-solver in order to avoid another exchange
811        (changes lab_sea) and clean up a little
812      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
813        help the adjoint (this also changes the results slightly)
814      - add a few "_d 0" where they had been missing in seaice_evp.F
815      - cleaning up: remove unused seaice_calc_rhs.F
816    o pkg/exf: some cleaning-up:
817      - change various "constants" into runtime parameters
818      - cleaned-up Large&Yeager04 routine which should eventually
819        replace exf_bulkformulae.F (changed names of S/R and CPP)
820        and merged various ALLOW_ATM_WIND options
821     only used with thsice pkg (in thsice_get_exf.F):
822      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
823        which are used when useStabilityFct_overIce=TRUE (= the default)
824      - change default values of ice & snow emissivity and scale downward LW
825        by ice & snow emissivity.
826    o pkg/thsice:
827     fix few little problems, in thsice_calc_thickn.F:
828      - growth vertically (and not laterally) if iceFrac == iceMaskMax
829      - melt only laterally if hIce < hThinIce (as the comments say)
830      and in thsice_extend.F:
831      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
832      - start to form ice as soon as the minimum ice-volume is reachable.
833     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
834      and cpl_aim+ocn
835    o pkg/kpp
836     - move computation of surface related input fields to KPP into a new
837       subroutine kpp_forcing_surf.F
838     - remove wrong (within bi,bj loops) EXCH calls.
839     - little cleaning (add argument myThid in last position, cvs header ...)
840     - for now, fix conservation problem by exchanging KPPviscAz (may not
841       be the best fix)
842    o pkg/seaice
843     - check for inconsistent evp parameter/cpp-flag combination
844     - remove leftover errIO flat for obsolete name list error handling
845    o OpenAD
846     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
847    
848    checkpoint59a
849    o pkg/seaice: some parameter clarifications and a little bit of clean up
850    o pkg/thsice: rename run-time parameters:
851       himin       -> hIceMin
852       himin0      -> hThinIce
853       hihig       -> hThickIce
854       i0          -> i0swFrac
855       transCoef   -> bMeltCoef
856       frac_energy -> fracMelting
857      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
858       with default values (for now) that do not change the results.
859      remove old version of thsice vars advection in pkg/seaice.
860    o in FFIELDS.h:
861      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
862      - make pLoad & sIceLoad always available (but still only used if
863         ATMOSPHERIC_LOADING is #define).
864    o pkg/kpp: replaced _KPP_RL with _RL
865    o bug fixes for vertical diffusivity computations when both KPP and
866        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
867        are no longer updating the vertical diffusivity array
868        (passed as argument) but are (re-) setting those arrays.
869    o pkg/seaice: fix bug in evp solver, while doing that
870      - change (improve?) discretization of stress computations for both
871        cgrid-lsr and evp solver
872      - add a new routine to compute strain rates
873      - the above changes lab_sea results
874      - add no slip conditions for evp solver (off by default), lsr-version
875        may follow
876      - fix exchange for shear at Z-points (does not change lab_sea)
877      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
878        (to force the user to pick a time step since there is not "safe" way
879        of choosing it)
880      - add principal stress diagnostics
881      - rearrange fields for evp a little to avoid having to call a: too many
882        exchanges and b: exchanges for stress trensor components which we do
883        not have.
884      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
885        of evp, complete rewrite for lsr case (latter is does not yet work
886        in all cases)
887    o pkg/kpp: add code to have mixing in shelf ice caverns
888      - add myThid to all kpp routines (long overdue)
889    
890    checkpoint59
891    o pkg/exf:
892      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
893        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
894      - move exf header files from lower_case.h to UPPER_CASE.h ;
895        add missing cvs Header & Name
896      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
897      - add namelist param. selectStressGridPosition, exf_monFreq
898      - retire many _CLIM routines, and remove data.exf_clim
899        + params moved to data.exf
900        + climsst, climsss now handled by exf_set_gen, i.e.
901          climss?period=0 refers to constant field,
902          climss?period=-12 to monthly forcing
903      - split up namelists in data.exf
904    o pkg/seaice:
905      - remove seaice_exch and seaice_exch_uv
906      - remove superfluous exchange of theta
907      - add myThid to seaice_budget_ocean/ice
908      - add new interface for atmospheric wind forcing (C-grid only)
909        + new routine
910        + two new field (taux, tauy for stress over ice)
911        + removed one global field (DAIRN) for C-grid case only
912    o pkg/thsise
913      - 2nd set of modifs for thsice adjoint in conjunction with exf
914    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
915    
916    checkpoint58y_post
917    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
918      vertical diffusivity, similar to that in MOM4; turned on using
919      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
920      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
921    o Added capability for 3D specification of background vertical diffusion
922      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
923      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
924      "data" file that contains the 3D vertical diffusivity coefficients.
925    o ice dynamics (pkg/seaice) with thsice thermodynamics:
926      - add code within pkg thsice to advect & diffuse sea-ice fields
927      similar to (and will replace) what has been added in  seaice_advdiff.F,
928      but: - conserving Mass, Heat & Salt.
929           - better when using non-linear advection scheme (not yet fully tested)
930           - can also be used in atmospheric set-up (for now, only the diffusion).
931    
932    checkpoint58x_post
933    o IO option for global-file compact format:
934      - add options when generating topology (utils/exch2/matlab-topology-generator)
935      - add I/O capability (pkg/mdsio).
936      - adapt utils/matlab/rdmds.m to read this format.
937      for now long-line format not yet supported by pkg/mdsio (& exch2).
938    o shelfice: add a few diagnostics
939    
940    checkpoint58w_post
941    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
942      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
943      (and replace horiVertRatio in NH code).
944      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
945                         and tutorial_plume_on_slope (sensitive to truncation)
946    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
947      directly to drive seaice model (C-grid only)
948    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
949     - reintroduce computation of wind from stress,
950     - compute tau (in exf_bulkformulae.F) from windstress averaged to
951       mass points to avoid tau = 0
952     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
953    o rdmnc.m: make it work with "global" files created with gluemnc
954    o rdmnc.m : some improvements in dealing with singleton dimension
955      (tested on all testreport mnc output files).
956    o genmake2: disable pkg/profiles if netcdf test fails.
957    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
958    o move call to cal_readparms up to make calendar parameters/variable available
959      to all packages
960    
961    checkpoint58v_post
962    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
963      useDynP_inEos_Zc tested.
964    o pkg/exf: changes to properly interpolate/mask/scale initial fields
965    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
966      and portions thereof.  See read_cs.txt for description and examples.
967    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
968      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
969      following the great-circle arc between those 2 points.
970    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
971      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
972    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
973     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
974     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
975     - still needs work (not working with some options ; efficiency to improve)
976       and serious testing.
977     - use this scheme for temperature & salinity in 2 advection test exp.:
978       advect_xy & advect_xz, respectively.
979    
980    checkpoint58u_post
981    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
982    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
983    o testreport: add option "-skipdir" to skip some test.
984    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
985      momentum calculation.
986    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
987    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
988      remove checkpoint.F and the_correction_step.F (no longer used);
989      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
990    o add option (linFSConserveTr) to correct for tracer source/sink due to
991      Linear Free surface
992    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
993    o pkg/thsice: fix reading mnc-pickups
994    
995    checkpoint58t_post
996    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
997    o pkg/mdsio:
998     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
999       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
1000       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
1001     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1002     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1003       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1004     - new S/R (to replace MDSWRITEMETA), which allows to write more
1005       informations (variable names, time ...) to meta files.
1006     - modify rdmds.m to give back the meta file content.
1007    o pkg/diagnostics: change vertical interpolation to be safer, and more
1008       flexible (define p-levels to interpolate to in data.diagnostics);
1009      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1010       diagnostic pointer.
1011    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1012    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1013    o fix multi-category seaice:
1014     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1015       SEAICE_MULTICATEGORY
1016     - fix short wave heat flux
1017    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1018       and allow to use EVP solver. Change forward lab_sea: test both EVP
1019       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1020    o Initial check-in of lab_sea adjoint
1021      (very similar to natl_box_adjoint/code_seaice)
1022      * used C-grid and EVP solver
1023      * used KPP, GM/Redi
1024      * uses inAdExact=.TRUE.
1025      * gradient checks fail for both ADM and TLM
1026        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1027        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1028        issue is related to forward mismatch between g77 an ifort
1029    o pkg/seaice: overhaul of thermodynamics
1030     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1031     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1032     - move a few global fields out of SEAICE.h into seaice_growth.F and
1033       make them 2D (FICE/QNETO/ ...)
1034     - remove FO (it is the same as QNETO)
1035     - introduce a few local fields to avoid modifying external fields such
1036       as atemp, etc.
1037    
1038    checkpoint58s_post
1039    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1040      changed exf_set_gen.F so that
1041        genperiod=0 means input file is one time-constant field and
1042        genperiod=-12 means input file contains 12 monthly means
1043    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1044      this affects truncation error ; generate new output file for exp. which
1045      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1046        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1047        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1048        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1049        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1050        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1051    o start implementation of deep-atmosphere and anelastic formulation
1052    o verification: remove 2nd copy of input files and use script "prepare_run"
1053      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1054    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1055    o profiles: fix for multithreaded case
1056    
1057    o diagnostics: rename few diags:
1058      s/'PRESSURE'/'RCENTER '/g
1059      s/'TICE    '/'oceFreez'/g
1060      s/'TAUX    '/'oceTAUX '/g
1061      s/'TAUY    '/'oceTAUY '/g
1062      s/'SWFLUX  '/'oceQsw  '/g
1063      s/DIFx/DFxE/g
1064      s/DIFy/DFyE/g
1065      and add few ocean-forcing diagnostics:
1066      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
1067    o modifications to pkg/seaice/growth.F and budget.F, which change results of
1068      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
1069      as actual snow thickness.  It now refers everywhere to effective snow
1070      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
1071    
1072    checkpoint58r_post
1073    o modifications to pkg/seaice/growth.F, which change results of
1074      lab_sea experiment: fixes pertain to melting snow over open water, to
1075      masking EVAP under sea ice, and to using the correct AREA variable for
1076      computations of EVAP, PRECIP, HSNOW, and GHEFF
1077    o add ability to read bathy, salt, and theta using MNC (off by def)
1078    o add flooding algorithm and advection of HSNOW for pkg/seaice;
1079      both are turned off by default and do no change any results
1080    o seaice advection with pkg/thsice: a step toward the use of non-linear
1081      advection scheme, but #ifdef or commented out for now (requires more EXCH).
1082    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
1083      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
1084      in natl_box (affects results @ truncation level: update output.txt)
1085    o multi-threading and IO:
1086      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
1087      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
1088        (needed to work with SingleCpuIO): tested in all verif. exp.
1089    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
1090      affects the results (but none of the verification test uses this scheme).
1091    o Adding some pkg/diagnostics capability to pkg/seaice
1092      (will certainly be subject to changes)
1093    o ctrl: adding new control variables:
1094      lwflux, lwdown, evap, snowprecip, apressure, runoff
1095    
1096    checkpoint58q_post
1097    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
1098      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
1099      high_res_cube configuration by 4% on Columbia.
1100    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
1101      add (in global_with_exf/code) a version of EXF_INTERP_READ without
1102      dynamical allocation (seems to work in multi-threaded).
1103    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
1104      single CPU io) so that TAF does not have to see EESUPPORT.h
1105    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
1106    
1107    checkpoint58p_post
1108    o obcs: stop if obcs is used with useCDscheme = .true.
1109    o shelfice:
1110     - fix a sign error so that no slip at shelfice interface works
1111     - remove stop for combination non-hydrostatic code and shelfice. That does
1112       not mean, that the results are correct, but at least they are numerically
1113       stable
1114    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
1115    o added adjoint exch routined for all exch*3d* routines
1116      and updated flow directives
1117    
1118    checkpoint58o_post
1119    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
1120      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
1121    o change controling S/R for writing pickup file (new S/R do_write_pickup)
1122      and clean-up reading/writing of pickup files.
1123    o fix local version of read/write pickup (NH part) in rotating_tank/code
1124    o simplify EXCH interface:
1125     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1126     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1127    o added the regrid package
1128    o shelfice:
1129     - add a simple boundary layer scheme to reduce noise
1130     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1131    
1132    checkpoint58n_post
1133    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1134       local variable (not in common block).
1135    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1136      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1137      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1138        to work with SingleCpuIO.
1139    o add "_d 0" to real constant of pkg/cfc subroutines ;
1140       update exp. cfc_exemple & tutorial_cfc_offline output files.
1141    o multi-threading and IO:
1142      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1143        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1144      - barrier before and after reading.
1145      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1146      - avoid using MDS_WRITELOCAL for LAND pkg output.
1147      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1148        common-block variables ; Allows multi-threading with master-thread IO.
1149    o change default MAX_NO_THREADS from 32 to 4 ;
1150      and stop cleanly when MAX_NO_THREADS is too small.
1151    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1152    
1153    checkpoint58m_post
1154    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1155       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1156    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1157       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1158       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1159    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1160        add MITgcm_tutorials (= code + all the tutorials)
1161    o ecco, option to compute cost for total ssh (mean+anom)
1162    o consistent with addition of ptracer and ssh in pkg/profiles
1163    o profiles: adding ptracer and ssh
1164    o testreport: change multi-test output-file name
1165      (from output.txt.{name} to output.{name}.txt)
1166    o profiles: now ok for mutli-tiles case
1167    o seaice: add 4 parameters for different advection schemes for area,
1168      (effective) seaice thickness, enthalphy, and snow height. Their default
1169      is the standard parameter SEAICEadvScheme
1170    o calc_gw:
1171     - add cosFacU in zonal viscous flux (harmonic.visc.).
1172     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1173       of tutorial_plume_on_slope.
1174    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1175    o calc_gw: true flux-form, account for horizontal grid spacing.
1176      update rotating_tank results, but not plume_on_slope (affected at
1177      truncation level, 11 digits).
1178    
1179    checkpoint58l_post
1180    o calc_gw:
1181     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1182     - remove side-drag for now (need to fix it); update plume_on_slope results.
1183     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
1184    o commit code to make SST/SSS weights spatially variable
1185      (based on either variable in-situ or variable initial T/S weights)
1186    o pkg/ecco:
1187      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
1188        now based on horizontally varying weights wthetaLev, wsaltLev
1189      * cost_averagesflags now returns year indices in addition to day, month
1190      * sflux balance is performed on annual basis
1191        (sflxumm, sfluxmm2, bal_sfluxmm)
1192      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
1193        including separate counting and multipliers
1194    o pkg/rbcs
1195      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
1196    
1197    checkpoint58k_post
1198    o testreport:
1199     - always build in dir. "build" (if not there, mkdir build instead of building
1200       & running in input)
1201     - run in dir run (if it exists), in build otherwise.
1202     - call prepare_run (if input/prepare_run exists)
1203     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1204    o pkg/exf modifications to interpolation and rotation routines for more
1205       reasonable treatment of North Pole singularity: for tracers North Pole
1206       value is set to northernmost zonal-mean value, for zonal velocity it is
1207       set to zero, and for meridional velocity it is set to northernmost value.
1208    o pkg/exf/exf_check_range.F
1209     - add tile index to diagnostics and move stop statement to the very
1210       end of the routine.
1211    o pkg/diagnostics: (diagnostics_main_init.F)
1212      define title of isomorphic variables according to the current config.
1213    o pkg/thsice with pkg/seaice dynamics:
1214    - fix domain of computation (interior only, required for exf) and do exchanges
1215    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1216    o towards a standard way of dealing with multi-threading in MONITOR
1217      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1218    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1219       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1220    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1221    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1222    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1223       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1224    o tracer advection:
1225     - clean-up and simplify calc_common_factors.F
1226     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1227       advection subroutine (but still not used within DST advection S/R)
1228    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1229    
1230    checkpoint58j_post
1231    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1232      from file (collects calls previously in FORWARD_STEP)
1233    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1234    o adjoint store dir. adjusted accordingly
1235    o genmake2
1236      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1237    
1238    checkpoint58i_post
1239    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1240      on wind stress (SEAICEstressFactor defaults to 1.)
1241    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1242      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1243    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1244      on CS-grid: no longer loosing mass.
1245    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1246    o pkg/ggl90: fix sloppy output and fix a bug
1247    o pkg/seaice: added SEAICEuseEVPpickup parameter
1248      - Set to false in order to start EVP solver with
1249        non-EVP pickup files when using SEAICEuseEVP
1250      - fix sign error in diffusion in seaice_calc_rhs
1251    
1252    checkpoint58h_post
1253    * Modifications for bottom topography control
1254      o replace hFacC by _hFacC at various places
1255      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1256      o add non-self-adjoint cg2d_nsa
1257      o update autodiff support routines
1258      o re-initialise hfac after ctrl_depth_ini
1259      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1260    * Adding verification for 5x5 box (4-layer) bottom topography control
1261    
1262    checkpoint58g_post
1263    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1264       used for mean seasonal cycle, mean diurnal cycle); add an example
1265       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1266    o pkg/ggl90:
1267      - add parameter (minimum surface kinetic energy)
1268      - fix bug (avoiding division by zero)
1269    o couple pkg/thsice to pkg/seaice:
1270      - modify advection in seaice to accomodate new scalar fields to be advected
1271      - only muliDimAdection scheme work with seaice/thsice
1272      - mapping of thsice-variables to seaice-variables, back and forth
1273      - does not break the verification experiments, but does not give the
1274        desired results either
1275    o pkg/seaice
1276      - make (default) second order advection a bit less confusing?
1277    
1278    checkpoint58f_post
1279    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1280      to pkg/seaice):
1281      - new routines thsice_map_exf and thsice_get_exf provide the interface
1282      - add an additional formal parameter to thsice_solve4temp
1283    o pkg/exf:
1284      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1285      - correct Stefan-Boltzmann constant
1286      - new parameter for longwave surface emittance
1287      - separate some stuff from exf_bulkformulae into new routines  
1288        exf_radiation, exf_wind
1289      - add new parameters and constants: longwave emissivity for ocean, ice
1290        and snow, evaporation parameters over ice
1291      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1292        either wind from stress or stress from wind
1293    o pkg/thSIce:
1294    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1295    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1296       and THSICE_CALC_THICKN
1297    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1298    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1299      to make debugging easier.
1300    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1301    o pkg/bulk_force:
1302      - clean-up comments and parameters ;
1303      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1304    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1305      generate new output for test-experiment: aim.5l_cs.thSI
1306    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1307      testreport accordingly
1308    
1309    checkpoint58e_post
1310    o SEAICE_CGRID adjoint done
1311    o R_STAR adjoint implemented.
1312      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1313      * need to sort out init. of h0facc, etc.
1314    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1315      to be able to use it in pure forward.
1316    
1317    checkpoint58d_post
1318    o upgrade simple test-experiment to tutorial example:
1319     step.1: duplicate the experiment and (step.2) will remove the old copy.
1320      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1321      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1322      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1323      tutorial_global_oce_biogeo    <- copy of dic_example
1324      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1325      tutorial_plume_on_slope       <- copy of plume_on_slope
1326      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1327      tutorial_global_oce_optim     <- empty for now (David ?)
1328      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1329     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1330    o correct a sign problem in cost_scat.F
1331    o obcs and ptracers: fix boundary conditions for advections schemes
1332      with larger stencil

1334    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1335      completeness
1336    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1337      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1338    o ptracers adjoint:
1339      * avoid extensive recomputatations
1340      * fix missing re-init. of gptr (missed by TAF)
1341    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
1342      me to turn off the excessive output to STDOUT that this package produces
1343    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1344      and add those terms in Vector-Invariant formulation.
1345    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1346      if the control period (xx_hfluxperiod etc) is 0
1347    o in profiles pkg, clean routines and fix details
1348    o in ecco pkg, reading ssh data:
1349      fix problem in case the model does not start at iter0=0
1350    o fix mnc-pickup/restart for ptracers
1351    o new package prifiles:
1352      code to compute profile-based cost by Gael Forget
1353      (modifs in ecco, ctrl, autodiff)
1354    o Benign bug fix in initialization (spotted by M. Mazloff) of
1355      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1356    
1357    checkpoint58c_post
1358    o adjoint: finish NLFS adjoint and provide reference output in
1359      verification/global_ocean.90x40x15/results_ad_nlfs
1360    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1361      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1362      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1363      with SEAICE_CGRID defined.
1364    o move calendarDumps from "data" to "data.cal" and clean-up the code
1365      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1366    o add useEXF & useCAL flags (for now, set in hard-coded way)
1367    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1368      (were missing in NH mode, and wrong in quasihydrostatic mode).
1369      waiting for Chris updated version of calc_gw to add those CALLs.
1370    o fix bug in quasihydrostatic S/R ;
1371      add a test for this option: global_ocean.90x40x15.qshyd
1372    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1373      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1374    o add on/off flag useOffLine for package OFFLINE
1375    o seaice:
1376      - modify advection so that it works also on the C-grid
1377      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1378        problem in multi-tile runs with C-grid
1379      - add flags for clipping ice velocities and/or masking solver forcing
1380      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1381        C-grid solver
1382      - added a few comments to seaice_diffusion.F
1383      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1384        are now exclusive)
1385      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1386        required re-ordering the code a little:
1387       + make DAIRN global variable (defined in SEAICE)
1388       + move computation of the viscosities eta and zeta into a new separate
1389         routine (because I need to recompute them in seaice_ocean_stress.F)
1390    
1391    checkpoint58b_post
1392    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1393      update output.txt of exp. aim.5l_cs.thSI
1394    o various mnc cleanups and improvements:
1395      + shrink lookup tables by factor of ~4
1396      + better error reporting when running out of lookup space
1397      + able to handle longer path/file names (up to 500 chars)
1398    o adjoint:
1399      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1400      - TBD: "hidden" mom_vecinv recomp. in dynamics
1401    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1402     (allow to differentiate between forcing components using new integer flags:
1403      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1404     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1405    o ecco
1406      - enable trend removal from SSH anomaly obs.
1407    o adjoint
1408      - a fix for PmEpR when #undef EXACT_CONSERV
1409      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1410      - try to fix "hidden" recomp. in forward_step for NLFS
1411        (NLFS seems broken sometimes after I checked it in)
1412    o seaice:
1413     - add c-grid version of the dynamic solver:
1414       + three new routines that are the c-grid substitute lsr, dynsolver
1415         and ostres
1416       + put a few fields that were local to dynsolver into global common
1417         blocks, so that I can move the computation of stresses etc into
1418         seaice_lsr (saves coding but may break the adjoint).
1419     - replace more hardwired parameters by runtime parameters
1420     - add ice masks that mask the rhs of the implicit solvers where there
1421       is no ice (commented out in seaice_dynsolver, because i am not sure
1422       if this works properly), eventually this should replace the clipping
1423       of ice velocities in seaice_dynsolver to +/-40cm/s.
1424    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1425      include it only where its needed
1426    o move balancing of fluxes before the call of external_forcing_surf
1427    o seaice:
1428      - correct units of turning angles (now they are really in degrees)
1429      - move computation of GWATX/Y out of main routine into dynsolver
1430      - initialize GWATX/Y in seaice_init
1431    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1432      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1433    o seaice: add runtime flags for turning angles (default to zero)
1434    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1435      and trend from exf forcing and ctrl control adjustments
1436    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1437      (since checkpoint57x_post)
1438    o change the default rotation period to 86164.s = the Earth rotation
1439    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1440      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1441    o seaice advection: add code for choosing between the default (2nd order
1442      central differences) and multiDim advection schemes provided by
1443      pkg/generic_advdiff
1444    o seaice:
1445      - removed all references to SEAICE_GRID.h fields from
1446        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1447        (cubed-sphere configuration will change a little)
1448      - grid computations in seaice_init are obsolete now.
1449      - cleaned up code a little so that is easier to read (hopefully).
1450      - added new (better?) discretizations of default advection and diffusion
1451        (turn on with SEAICEuseFluxForm)
1452      - replace 1 in 3d global fields by kSurface in growth.F
1453      
1454    checkpoint58a_post
1455    o seaice:
1456      - bug fix in advect.F
1457    o shelfice:
1458      - separate shelfice load anomaly from pload (breaks with time
1459        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1460        Its default is 0., but it may be computed more cleverly from (unknown)
1461        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1462        done offline. A good approximation of the pressure load anomaly is
1463        necessary to avoid large initial adjustment processes underneath
1464        deep-reaching shelfice.
1465      - small fix in ISOMIP shelfice_thermodynamics
1466      - add more sophisticated thermodynamics of Hellmer (1989), this is
1467        now the default
1468      - give a few constants more intuitive names
1469    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1470      if bulk formulae are used in long integration (especially EmPmR). Turn
1471      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1472      if balancePrintMean, the imbalance that is substracted is printed to
1473      STDOUT.
1474    o fix bug (typo) in obcs_apply_eta.F
1475    o add a new package shelfice which enables us to model the circulation
1476      underneath shelf-ice with draughts of hundreds of meters.
1477     - works
1478     - to do: + include improved thermodynamics
1479              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1480                instead of new field kTopC
1481              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1482                instead of new field R_shelfIce and new code in ini_depth.F
1483                and ini_mask_etc.F?
1484              + adjust vertical mixing schemes?
1485    o seaice pkg:
1486     - add a cpp-flag to include a simple formula for a salinity dependent
1487       freezing point of sea water at the surface
1488     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1489       meridional stresses are now different (and hopefully correct)
1490    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1491       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1492       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1493    o pkg/diagnostics: add options and parameters for regional-statistics
1494       diagnostics ; define regions by reading a region-mask from a file
1495       (might add other options later)
1496    o pkg/bulk_force:
1497     - add option and parameters to use AIM surface-flux formulae.
1498     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1499       others forcing fields (defined in PARM05, parameter file "data") are loaded
1500       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1501     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1502     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1503     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1504       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1505     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1506    
1507    checkpoint58
1508    o add "--embed-source" option to genmake2 which, when the supporting
1509      tools can be compiled (as determined by genmake2) will turn on the
1510      embed_files package which then embeds the entire MITgcm source code
1511      (*.[fFhc] + Makefile) used for the build within the executable
1512      - requested by CNH but off by default
1513      - adds a paltry <9MB to the mitgcmuv executable in most cases
1514      - only writes the output when useEMBEDSRC in eedata is true
1515    o clean up 3-dim. relaxation codes:
1516      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1517      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1518      * Thanks to Tom Haine for testing!
1519    
1520    checkpoint57z_post
1521    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1522      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1523    o fix the pickup behavior for obcs in combination with ptracers
1524    o fix a bug in ptracers_external_fields_load
1525    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1526      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1527    o transfered surface NH pressure to eta field (if exactConserv).
1528    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1529         and update lab_sea output.txt file.
1530    o completing 3-dim. relaxation code: additional term
1531         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1532      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1533      * At compile time, in "EXF_OPTIONS.h" set
1534          #define  ALLOW_CLIMTEMP_RELAXATION
1535          #define  ALLOW_CLIMSALT_RELAXATION
1536      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1537          tauThetaClimRelax3Dim = 15552000.0,
1538          tauSaltClimRelax3Dim  = 15552000.0,
1539      * 3 cases:
1540          1) Use a constant-in-time 3-dim. field
1541          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1542          3) Real-time relax. to time-evolving prescribed field
1543    o Adding Laplacian-type smoothness constraint on
1544      initial and boundary (forcing) controls (ic, bc)
1545      * enable at compile-time via
1546        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1547      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1548      * Absolute scale somewhat unclear so far
1549      * no area weighting was included since no other cost term does so far
1550    
1551    checkpoint57y_post
1552    First step for a NLFS adjoint
1553    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1554    o new init. routines for calc_r_star, calc_surf_dr
1555    o still need to deal with ini_masks_etc
1556    o testreport seemed happy
1557    checkpoint57y_pre
1558    
1559    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1560    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1561    o add new offset feature to offline pkg (plus minor cleanup)
1562    o cfc fixes for final year of integration
1563    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1564      be in GCHEM_OPTIONS).
1565    
1566    checkpoint57x_post
1567    o fix testreport Pb in multiple test experiment.
1568    o cleanup our namelist syntax in verification:
1569      - make it more F95 standards compliant (some work still needed)
1570      - allows the vast majority of our tests to work with gfortran
1571    o Non-Hydrostatic:
1572     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1573     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1574    o Allow to apply AB on T,S rather than on AB(gT,gS):
1575     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1576     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1577       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1578     - need a "clever" read_pickup to restart from the other AB formulation
1579    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1580    o remove some unused variables (reduces number of compiler warnings)
1581    o adjoint
1582      * Disable useVariableViscosity for adjoint for time being
1583        (there are a number of extensive recomputations)
1584      * Initialize certain variables needed for adjoint
1585    
1586    checkpoint57w_post
1587    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1588                 fix the singleCpuIO RS version of MDSWRITEFIELD
1589       and add a WARNING if using globalFiles=T with multi-processors.
1590    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1591      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1592    o tracer advection scheme:
1593      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1594       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1595       was not very convenient).
1596      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1597       (further tests needed for the implicit DST & Flux-Limiter schemes).
1598    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1599      and sRef for convenience, handy, when you want to initialize
1600      ptracers in a large domain with a constant non-zero value. Also,
1601      untangle ptracers_init.F a little.
1602    
1603    checkpoint57v_post
1604    o change dome exp. to use variable viscosity in side-drag terms.
1605    o remove all the files from the cfc_offline test since they are now
1606      incorporated into tutorial_cfc_offline which has been producing
1607      identical results for a few days of testing
1608    o add new parameter: sideDragFactor to enable half-slip-side BC
1609      and change side-drag S/R to use viscosity from mom_calc_visc
1610      (can switch back by setting sideDragFactor=0.); affects results at
1611      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1612       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1613    o vorticity & strain are now computed without masking, to account for
1614      no-slip-side BC in variable viscosity calculation ; mask is applied
1615      anyway later on, before computing advection/coriolis terms.
1616    o modify exp4 to test new obcs support for reading from external files
1617      and for passive tracers
1618    o fix behavior of ptracers_monitor when monitor output is written to a
1619      netcdf-file; still not independent of monitor.F (writes in the same
1620      file).
1621    o change default value of tRef (put a uniform, meaningful value for ocean
1622      & atmos) and initialize sRef (was missing, as Martin mentioned).
1623    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1624      to be proportional to enstrophy dissipation length.  Thus,
1625       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1626      This is now consistent with Smagorinsky and with the manual.
1627    
1628    checkpoint57u_post
1629    o OBCS and PTRACERS: add open boundary support for passive tracers
1630      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1631        OB-values from file; this is not different from the way theta and salinity
1632        are treated
1633      - however, Orlanski-radiation conditions are not supported, and the model
1634        will stop if you use pTracers and Orlanski at the same time.
1635      - beefed up the rountine obcs_external_fields_load: now only those open
1636        boundary values are overwritten with values from files for which there
1637        are really files, otherwise the OB-fields remain untouched. This makes
1638        it possible to use different OBs at different ends of the domain (as
1639        with EXF)
1640    o reduce number of exch calls in shap_filt (s2).
1641    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1642      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1643    
1644    checkpoint57t_post
1645    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1646    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1647      same truncation, independent of the face number: affects affects several
1648      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1649    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1650      note that biharmonic viscosity + no-slip was not tested in any experiment.
1651    o fix bug in non-linear free-surf side-drag ; generate new output for
1652      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1653    o make mnc honor the writeBinaryPrec flag for most kinds of output
1654    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1655    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1656      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1657    o add brackets in multi-terms sum to get same truncation, independent of
1658      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1659      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1660    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1661      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1662      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1663      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1664      Suggested values of viscosity parameters found in mom_calc_visc.
1665      Many new viscosity diagnostics available.
1666    
1667    checkpoint57s_post
1668    o Add clearing-house for viscosity calculations, mom_calc_visc and
1669      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1670      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1671      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1672      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1673      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1674      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1675      ViscAhStrain and viscAhTension are now retired.
1676    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1677    o In response to JMC's bug report, genmake2 now ignores any soft-links
1678      that it finds in the *current* directory when searching for files.
1679      Soft-links found in any other source directories will still work as
1680      they did before.
1681    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1682      a C routine to unlimit the stack size
1683    o mnc-ify pkg/aim snapshot vars
1684    o mnc-ify pkg/land as requested by Daniel
1685    o various changes to mnc including:
1686      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1687      - output can now be grouped so that all files within a group
1688          change the ITER portion of their names in lock-step together
1689      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1690          and works with both EXCH1 and EXCH2 (but needs more testing)
1691      - writing works for all verification test cases w/ g77 on Linux
1692    
1693    checkpoint57r_post
1694    o make MNC variable initialization happen earlier
1695    o add diagnostics for (almost) each term of the momentum Eq.
1696    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1697    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1698    o remove MINIMAL_TAVE_OUTPUT option ;
1699      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1700    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1701      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1702    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1703    o add time-dependent SST, SSS control
1704    o cost terms in ecco/ modularized (new cost_generic.F)
1705    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1706    o new infrastructure for seaice model vs. obs misfits in seaice/
1707      * driver from the_main_loop.F is seaice_cost_driver.F
1708      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1709      * gradient check in Exp. 6a of natl_box_adjoint/
1710    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1711      (see README file)
1712    
1713    checkpoint57q_post
1714    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1715    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1716      - bug was reported by Jean-Michel and Ian Fenty
1717    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1718      update exp. cpl_aim+ocn output.
1719    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1720      Needed for high-res. runs with large global files
1721      to be able to limit tapelev size
1722    o Changed some tests for adjoint:
1723      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1724      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1725      * global_ocean.90x40x15/ back to default 3-level checkpointing
1726    o Modifications to enable scripted COMMON to MODULE conversion
1727      * verification/OpenAD/code/ has necessary scripts and description;
1728      * converts, compiles and runs successfully;
1729    
1730    checkpoint57p_post
1731    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1732    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1733      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1734    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1735    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1736      (was already the case for dissipation with mom_vecinv,
1737       and also the case for grad.PhiHyd when staggered-timeStep)
1738      This will allow to put dissipation out-off the AB time-stepping.
1739     Unfortunately, affects truncation error. Update output of exp. that "fails"
1740      (cg2d matching number) and leave the others for later: front_relax(10),
1741      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1742      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1743    
1744    checkpoint57o_post
1745    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1746      (2) its ready to be documented during the 20050801 DocFest
1747    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1748      for ideal_2D_oce and lab_sea on linux_ia32_g77
1749    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1750      in global1x1_tot/code_seaice_adj to access indices 32, 33
1751      (worth another tag)
1752    
1753    checkpoint57n_post
1754    o adding precip control xx_precip 32
1755    o adding swflux control xx_swflux 33
1756    o Replacing 10 forcing penalty cost routines by 1 generic.
1757    o Implementing partitioning in time-mean and variable adjustment
1758      for atmos. state.
1759    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1760    o in natl_box_adjoint:
1761      * updated exp 1 to 10
1762        (but does not have time-mean vs. variable split results yet)
1763    o updated global1x1/*_seaice_adj/
1764      to incorporate latest changes
1765    o enable useSingleCpuIO for mdsio vector routines
1766      (applies in particular to tapelev I/O)
1767    o removed inefficient K-loop in all active_file*control*.F
1768    
1769    checkpoint57m_post
1770    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
1771      and advect_cs (use EXCH-2 and standard cs-32 grid files).
1772    o pkg/exch2: filling of face-corner halo regions is optional
1773      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
1774    
1775    checkpoint57l_post
1776     tag before updating tutorials (pre-release-2)
1777    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
1778       for output and interpolation of input fields onto model grid)
1779    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
1780       Affects results of exp. rotating_tank ; update output.txt.
1781    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
1782          and taking the square quantity and/or using a fraction-weight field.
1783    o fix aim_diagnostics_init.F mate numbers.
1784    o add mnc output capability to diagnostics/diagstat and update
1785      our cvsignore files for the ACSII output generated
1786    
1787    checkpoint57k_post

1789      new EXF diagnostics output.
1790    
1791    checkpoint57j_post
1792    o exf
1793      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1794        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1795        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1796      * extended diagnostics output
1797        - now includes all EXF variables
1798        - hs, hl moved to common block
1799        - separate S/R for diagnostics, called after ctrl vector is added
1800        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1801        - EXFqnet contains true Qnet (i.e. includes qsw)
1802      * updated verif. lab_sea, global_with_exf
1803      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1804        to ensure that diagnostics sees a true EXFqnet
1805    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1806    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1807      several times with different frequencies.
1808    o mnc-ify the thsice package as requested by Daniel Enderton
1809      - the monitor--MNC output needs work
1810      - many attributes need to be added (most are currently blank)
1811    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1812      - many attributes need to be added (most are currently blank)
1813    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
1814    o add Sadourny like discretization to the 4th.O vorticity advection scheme
1815    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
1816      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
1817         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
1818    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
1819     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
1820    
1821    checkpoint57i_post
1822    o Diagnostics package was changed: diagnostic allocation is now deactivated
1823      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1824    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1825      add 1rst Order upwind vertical Shear.
1826    o add a quick fix for A/B checkpointing in OFFLINE mode
1827    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1828      end-run around the C/Fortran linking horror in eesup/src/timers.F
1829    o added pkg/runclock: allows user to terminate run based on wall clock
1830    o added non-hydrostatic scaling parameter: nh_am2
1831    o pkg/my82: futile attempt to make results compiler-independent by adding
1832      some "_d 0", etc. no effect.
1833    o for mnc output, fill the 'T' coordinate var with myTime and create a
1834      separate 'iter' variable for iteration count
1835    o pkg/diagnostics:
1836      add new capability: output of Global/Regional & per-level statistics ;
1837      tested against monitor output (including land & thSIce) on various exp.
1838    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1839    
1840    checkpoint57h_done
1841      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1842      data.diagnostics, data.gchem, data.ptracers) is done.
1843    
1844    o pkg/diagnostics: prepare for Global/Regional statistics.
1845      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1846    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1847      and rename it: DIFFERENT_MULTIPLE
1848    
1849    checkpoint57h_post
1850    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1851    o pkg/diagnostics: change output frequency, now in seconds (instead
1852      of Nb of iterations). This requires to change data.diagnostics.
1853    checkpoint57h_pre
1854    
1855    o in mnc, let the user create the output dir if both mnc_outdir_date
1856      and mnc_outdir_num are false
1857    o add fflags() to pkg/diagnostics which allows one to specify, on a
1858      per-file basis, the file precision [default behavior is unchanged]
1859    o added diagnostics to pkg/kpp, including computation of mixed layer
1860      depth based on a temperature/density criterion
1861    o updated verification/natl_box to test the new pkg/kpp diagnostics
1862    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1863    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1864    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1865      not mnc -- this mistake was found by JMC and is now corrected
1866    
1867    checkpoint57g_post
1868    o add Adams-Bashforth 3rd Order time stepping:
1869      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1870      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1871    checkpoint57g_pre
1872    
1873    o make lambda[Theta,Salt]ClimRelax spatially varying
1874      (default remains spatially uniform constant based on tau)
1875    o added new control variables
1876      * init. uVel, vVel, etanN
1877      * lambda[Theta,Salt]ClimRelax
1878    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1879      (suggested by G. Forget)
1880    
1881    checkpoint57f_post
1882    o add parameter "baseTime" = model base time = time at iteration zero
1883      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1884      account for baseTime shift
1885    o move Coriolis arrays from PARAMS.h to GRID.h
1886    checkpoint57f_pre
1887    
1888    o mnc-ifying the seaice package
1889    o introduced an alternative length scale calculation for use in the limiting
1890      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1891    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1892    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1893      as well as grad(vort3).  Made it compatible with both approximate form
1894      for the cubed sphere and full form of these gradients.  Added flag
1895      useFullLeith to select between approximate and full form.  
1896    o add "d0" in getcon.F to reduce differences between compilers/platforms
1897      update output.txt of exp. fizhi-gridalt-hs
1898    o change port_rand funtion to allow to set the seed.
1899    o fix obscure MNC bug involving conversion between reals and integers
1900      - it caused no problems with certain (eg. gcc, ifc) compilers but the
1901        new version is now more standards-compliant
1902    o adjoint-related modifications
1903      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
1904      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
1905      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
1906    
1907    checkpoint57e_post
1908    o Adding eddy stress controls a la Ferreira et al.
1909    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
1910    
1911    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
1912      update output.txt of exp. fizhi-gridalt-hs
1913    o add more "Z" dimensions and associated coordinate vars to MNC
1914    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
1915    o parameter calendarDumps: when set, approximate months (30-31 days) and years
1916      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
1917      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
1918      months and years.  Requires pkg/cal.
1919    o diagnostics: add pickup functionality
1920      - off by default for backwards compatibility
1921      - current version only uses MDSIO -- MNC will be added
1922    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
1923    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
1924    
1925    checkpoint57d_post
1926    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1927    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1928      output from the diagnostics package
1929    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1930    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1931      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1932    o add coordinate variables to the MNC output from the diagnostics package
1933    o change MNC-flags default value: true when useMNC=TRUE
1934    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1935      the ability (off by default) to read the grid information using MNC
1936    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1937    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1938    o do snap-shot diagnostics at the middle of the time-interval (instead of
1939      at the end).
1940    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1941      new test for AIM with thSIce + slab-ocean
1942    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1943    o move state variable diagnostics to the beginning of the time step ;
1944      (note: still needs some work specially for snap-shot diagnostics)
1945      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1946    
1947    checkpoint57c_post
1948    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1949    o generate new output.txt files on faulks with g77 & the new -ieee option
1950    checkpoint57c_pre
1951    
1952    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1953      update output.txt of exp. global_ocean.90x40x15
1954    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1955      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1956    o add saltFlux(+File) forcing capability with periodicExternalForcing
1957    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1958    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1959    o improvements for the MNC output from DIAGNOSTICS:
1960      - correct handling of the unlimitied dimension
1961      - all dims now have associated coordinate variables
1962      - variables located at U, V, and Corner ("Z") points are now written
1963        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1964        *all* data points are output
1965    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1966    o added pkg/seaice/seaice_monitor.F
1967    o mdsio_readfield.F can now read files visible only to master MPI process.
1968    o pkg/seaice: some test code for ice-modified ocean stress
1969    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1970      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1971      spurious negative numbers for precipitation and humidity.  Will cause
1972      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1973    o pkg/ctrl/
1974      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1975        May be enabled via doPackDiag
1976      *  introduce z-scaling of
1977         + gradient (doZscalePack) and
1978         + control (doZscaleUnpack)
1979    o pkg/mdsio/
1980      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1981      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1982    
1983    checkpoint57b_post
1984    o simplify options in diagnostics_fill arguments (remove weird combinations)
1985    o fix MNC coordinate variables so that they now contain per-face index
1986      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1987      general, EXCH2 grids are only aligned to a "local" coordinate system
1988    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1989    o Implement instantaneous output within pkg diagnostics:
1990      setting a negative frequency in data.diagnostics produces
1991     "snap-shot" output (as opposed to time-average if freq > 0)
1992    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1993      NOTE: change ptracer diagnostics name: use 2 characters to work with
1994            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1995    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1996      becomes the coordinate variable for the 'T' dimension
1997    o add CF-style coordinate variables to MNC
1998      - just a first cut:  numbers are meaningless on the cubesphere and
1999        missing along the T axis but otherwise it works!
2000    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
2001    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
2002    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
2003      this is based directly on what the model compute, so that the content of
2004      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
2005    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
2006    o clean up build options files for SunOS, in particular
2007      - remove -traditional from xmakedepend
2008      - change -xarch=v9 to -xarch=native for f77
2009      - restore use of make (not gmake)
2010      - add CC=gcc if using g77
2011    o changes per discussion of AM, JMC, & EH3 today:
2012      - move redundant "grid" variables out of "state" -- in preparation of
2013        creating proper CF-style coordinate variables and in recognition
2014        that any/all grid variables can be easily copied (eg. w/NCO) from
2015        the grid files into any of the other NetCDF files
2016      - *always* output grid variables with MDSIO (this will eventually be
2017        changed)
2018      - output MNC grid file if useMNC is true
2019    o every instance of _END_MASTER() has been found and replaced with
2020      _END_MASTER( myThid ) in order to satisfy certain picky Sun
2021      preprocessors
2022    o re-arrange diagnostics pkg initialisation:
2023     - allow each package to extend the available diagnostics list
2024     - add some checking and fix small problems (multi-threaded, ...)
2025     - new S/R diagnostics_fill (replace fill_diagnostics):
2026       look through the short list of active diag. (instead of the long list)
2027       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
2028    
2029    checkpoint57a_post
2030    o this set of changes restores TAMC compatibility
2031      tested for global_ocean.90x40x15 adjoint on trough
2032      (what a pain)
2033    
2034    checkpoint57a_pre
2035    o some modifs in tools/build_options for sunos
2036    o call ctrl_pack for ctrl at end for optimcycle=0
2037    
2038    checkpoint57
2039    o add horizontal bi-harmonic viscosity for vertical velocity
2040      - new parameter viscA4W (defaults to viscA4)
2041      - affects only non-hydrostatic code
2042      - to be done: no-slip lateral boundary conditions
2043    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
2044    o implement Implicit Vertical advection for pTracers
2045    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
2046      (implemented also for implicit vertical diffusion & advection)
2047    o OBCS: extend application of tracer open boundary conditions
2048      to a strip beyond the boundary of width Olx/Oly
2049    o add call monitor to TAF set of required calls (flow directives)
2050      and include in natl_box_adjoint
2051    o untangle a few ifdefs related to cost, ctrl, autodiff
2052      untangel a few ALLOW_ECCO_OPTIMIZATION
2053    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
2054      (theta2, salt2 in ecco_cost_weights)
2055    
2056    checkpoint56c_post
2057    o OBCS as control variables
2058      - update ctrl_ad_diff.list, obcs_ad_diff.list
2059      - remove balance of obcs controls from default
2060      - fix index bug nobcs in ctrl_init
2061      - fix dummy fields filen in ctrl_pack
2062      - add dummy weights for obcs
2063    o lsopt: comment out fort.94 output
2064    o optim:
2065      - remove unnecessary header files
2066      - adjusted namelists
2067      - add xerbla.F to Makefile
2068    o exf:
2069      - multiple modifications of exf_check_range
2070      - unit change in exf_init_runoff from [m/year] to [m/s]
2071    o mdsio:
2072      - i/o-vector change debugLevel from debLevA to debLevB
2073    
2074    checkpoint56b_post
2075    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
2076      is called from DO_THE_MODEL_IO
2077      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
2078      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
2079      - clean up PTRACERS_WRITE_TIMEAVE a little
2080    o add another verification experiment that tests both the cfc-pkg and
2081      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
2082      reactive tendencies treated inline with regular timestepping
2083    o testreport previously did a lousy job of comparing small numbers, so
2084      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
2085      implemented in the little c-progam tmp_cmpnum.c which is embedded in
2086      testreport.
2087    o ptracers_monitor: bug fix for MPI
2088    
2089    checkpoint56a_post
2090    o GCHEM: finish reorganizating the package
2091      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
2092        (introduces another 3D-array for each passive tracer, but only if
2093        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
2094        gchemTendency is not needed because the timestep is done separately)
2095      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
2096      - GCHEM is now---more or less cleanly---separate from PTRACERS
2097      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
2098        so clear to me how that should be done in a general way.
2099    o CFC: improve formatting of output in CFC_ATMOS
2100    o PTRACERS:
2101      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
2102        that ALL experiments with ptracers enable can be checked. This makes
2103        GCHEM_MONITOR obsolete.
2104      - include a runtime parameter PTRACERS_monitorFreq that defaults to
2105        monitorFreq
2106      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
2107    o add PTRACERS (PTR0[1-5]) to testreport output
2108    o exf_check_range:
2109      * default changed to .TRUE.
2110      * will check values for niter0 if debLevA, every timestep if debLevB
2111      * STOP in exf_check_range if 'out of range'
2112      * range chosen generous to allow for potential extema
2113      TBD: a version with stricter range
2114           permitted range would be runtime parameters

2123      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
2124        this flag is now only visible within GCHEM-pkg routines.
2125      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
2126        be replaced by a 3D array that is computed before thermodynamics; for
2127        this, the tracer ID iTracer had to be included into the parameter list
2128        of ptracers_forcing
2129      - set up forward_step to call gchem_forcing, that will replace
2130        gchem_forcing_int in ptracers_forcing
