4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
8      to reduce length of 1.D array print in STDOUT.
9    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
10      + use 48 tiles (16x8): this will allow to test "blank tiles".
11    o start to test MPI + multi-threaded (change testreport to skip tests
12      where number of tiles do not match).
13    o genmake2: add option "-omp" to turn on Open-MP ;
14      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
15    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
16      and keep the original tile numbering. Note: compatible with old
17      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
18    
19    checkpoint61l
20    o Overlaps had been forgotten in calculating ijk keys : fixed
21    o fix cyrus makedepend for gcc 4.4
22    o experiment fizhi-cs-aqualev20:
23      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
24      and generate new output. Note: new output is much closer to the old
25      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
26      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
27    o pkg/fizhi:
28     - change to avoid indices going deliberately over array-bounds
29     - remove unnecessary MPI stuff
30     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
31     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
32       does not go over array-bounds and therefore returns reliable output.
33     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
34       this S/R has 4 output arguments, which are used inside "get_alarm";
35       when it is called with the same variable "ndum" in place of several
36       output arguments, this produces weird side effect inside "get_alarm"
37      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
38       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
39       address) and produces error.
40    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
41    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
42       update lab_sea.lsr & lab_sea.salt_plume results
43    o pkg/seaice:
44      Major overhaul of the LSOR solver: change discretization from original
45      finite differences to finite volume. The old routine is still in the
46      file seaice_lsr.F and can be turned on with the CPP-flag
47      SEAICE_OLD_AND_BAD_DISCRETIZATION
48      Along with this change, the discretization of the strain rates is changed.
49      The same flag turns on the old discretization in seaice_calc_strainrates.F
50      All verification experiments with seaice are affected (except for
51      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
52      results by setting the above flag.
53      Further changes involve changes in defaults:
54      - ALLOW_FLOODING is defined and turned on by default
55      - SEAICEadvSnow = .true. is now the default
56      - SEAICEadvSalt = .true. is now the default
57      - SEAICEadvAge  = .true. is now the default
58      - SEAICE_clipVelocities  = .false. is now the default
59                                         (as per J. Zhang's recommendation)
60      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
61        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
62      - seaice_growth: replace computation of UG by a simple copy from wspeed
63    
64    checkpoint61k
65    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
66      seaice_lsr: fixed a few metric terms,
67                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
68                  add more debugging diagnostics
69      seaice_evp: removed superfluous many metric terms of FV discretization
70                  of stress divergence
71                  affects lab_sea, lab_sea.hb87
72      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
73                  of stress divergence for non-evp solver
74                  (this part is not tested anywhere)
75      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
76                  they were effectively only half slip
77                  affects lab_sea.hb87
78      updated all relevant verification experiments (except lab_sea//output_adm.txt
79        which was left over, but fails at level 7 & 6)
80    
81    checkpoint61j
82    o pkg/seaice: turn a few hard wired parameters into run time parameters
83    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
84      time in seconds as promised by the usints in seaice_monitor and exf_monitor
85    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
86      that are not cubed-sphere grids
87    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
88    o pkg/ctrl:
89      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
90    o non-hydrostatic (calc_gw.F):
91      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
92      update output of exp. global_ocean.cs32x15.viscA4
93    o remove backward compatibility for thetaMin,phiMin
94      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
95    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
96      interpolated wind field not only for curvilineargrid=.true., but also
97      for a rotated grid (rotateGrid=.true.)
98    o pkg/exf: add capability to bypass interpolation for runoff
99      by setting yet another CPP-flag
100    o eesupp/src, B-grid exchange:
101      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
102    o autodiff
103      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
104      allows to switch to single-prec common blocks;
105      corresponding switch occurs in tamc.h, integer isbyte
106      TAF store directivs "byte" and "kind" seem equivalent;
107      Most tamc.h have been updated correspondingly.
108    
109    checkpoint61i
110    o autodiff:
111      fix autodiff_sore/_restore indices for obcs
112      (spotted by I. Hoteit, M. Mazloff)
113    o pkg/autodiff, pkg/ctrl:
114      Add flag to reduce all tapelev I/O to single-prec.
115      In data.ctrl set
116        doSinglePrecTapelev = .TRUE.
117    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
118      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
119    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
120      real fresh water flux (not yet)
121    o pkg/mdsio & rw:
122     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
123     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
124    o pkg/flt:
125     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
126       init_fixed & ini_varia.
127     - clean-up & simplify linear interpolation S/R:
128       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
129     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
130     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
131     - add vert. coordinate & horiz. indices to output files.
132     - change vertical position in initial condition, from index to depth [m].
133     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
134       (easier to get to a curvilinear grid) ; delX,delY no longer used.
135    o pkg/ggl90: a few modifications:
136     - fix bottom boundary condition, and interpolation of KappaE
137       near top and bottom
138     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
139     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
140     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
141    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
142      (maintain temporary backward compatibility, until next checkpoint)
143    
144    checkpoint61h
145    o pkg/diagnostics with "periodic averaging diagnostics":
146      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
147    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
148    o pkg/obcs: fix loop ranges for balancing code
149    o pkg/flt:
150     - improve criteria for finding which tile owns a float.
151     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
152    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
153      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
154      with ocean biogeo)
155    o pkg/flt:
156     - do some cleaning and fix the restart ;
157     - add output.txt in flt_example/results to get this pkg tested.
158    o genmake2: add an EXTENDED_SRC option and flag.
159       for now, cannot be turned on on command line (only through genmake_local)
160    o pkg/mdsio: read/write vector:
161     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
162     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
163       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
164     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
165      (drop to 4 digits matching for grad). But this test does not look very
166      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
167    
168    checkpoint61g
169    o pkg/flt:
170      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
171       + make OPTIONS file more standard.
172      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
173      - fix _BYTESWAPIO CPP-Flag
174      - standard reading of file-parameter "data.flt"
175      - fix argument list of S/R FLT_RESTART
176      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
177    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
178    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
179      a still unfixed compiler/optimization bug
180    
181    checkpoint61f
182    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
183      update results of global_ocean.cs32x15.icedyn test.
184    o move getcon.F from model/src to pkg/fizhi.
185    o pkg/exf: add parameter for extrapolation of temp up to the surface
186       and option to prevent negative evap (in bulk_largeyeager04 only).
187    o Prather Advection scheme: fix tracer conservation for divergent flow
188      (e.g., when using NonLin Free-Surface).
189    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
190    o gmredi (Visbeck-variable-K):
191     - add more parameters to Visbeck-variable-K.
192     - use a 5 points average for dSigmaR in Visbeck-K calculation
193       (more "homogenous": same stencil and same weights as in dSigmaH)
194     - update output of ideal_2D_oce experiment.
195    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
196      (#undef REAL4_IS_SLOW)
197     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
198       coordinate variable
199     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
200       (surface forcing fields), removes some of the functionality
201     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
202     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
203       probably not all: copy _RS surface flux fields to RL field before
204       calling DIAGNOSTICS_FILL
205     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
206       real*4 (CALL EXCH_*_RS) versions.
207     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
208       (generate new output).
209    
210    checkpoint61e
211    o gmredi (Visbeck-variable-K):
212      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
213      - change computation of Visbeck-K where Slope > Smax :        
214        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
215        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
216    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
217      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
218    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
219    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
220      does not become too large (to avoid precision problems in implicit-diffusion
221      solver); update ideal_2D_oce output.
222    o pkg ggl90:
223      - in ggl90_cal.F: compute only one set of visc/diff, used to
224        step forward TKE/T/S/momentum
225      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
226        have Prandlt =1)
227    o gmredi (fm07):
228      - add lower limit on Transition layer thickness + lower limit on 1/lambda
229      - allow to set few more params from data.gmredi
230    o pkg ggl90:
231          - add missing sqrt(2) factor in computation of mixing length
232            scale in ggl90_calc.F
233            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
234    
235    checkpoint61d
236    o adjoint modifs
237      - adapt to new field rhoInSitu
238      - allow to revert from StoreDynVars2D, StoreDynVars3D
239        to individual fields
240        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
241    o store 3-D (in-situ) density in commom block (DYNVARS.h)
242     - save 1 rho computation.
243     - no longer modify T & S inland when using down_slope pkg.
244    o gad_som : allow to switch to SOM advection for T & S without corresponding
245      pickup files (using new S/R: MDS_CHECK4FILE).
246    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
247      (for useSingleCpuIO to work in multi-threaded)
248    o pkg/shelfice:
249     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
250       with SHELFICEtopoFile in data.shelfice
251     - move code for reading ice shelf topography and modifying hFacC into separate
252       subroutines of the shelfice package
253     - separate initialisation of "fixed" and "variable" variables
254     - kTopC is not (yet) replaced by kSurfC, although this is possible
255    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
256    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
257      and rename:
258      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
259      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
260    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
261    
262    checkpoint61c
263    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
264      to add mass source/sink of fluid in the interior (3-D generalisation
265      of oceanic real-fresh water flux).
266    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
267    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
268    o new pkg: down_slope
269      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
270      - presently, modify T & S inland (dwnslp_calc_rho.F).
271        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
272      - implementation for ocean in P-coords not tested.
273      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
274    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
275      (to facilitate conversion of oceanic pkg to p-coordinate).
276    o change FIND_RHO to FIND_RHO_2D :
277      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
278    o new pkg: cheapaml
279    
280    checkpoint61b
281    o exch2:
282      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
283      - no longer depend on the order sequence (N,S,E,W).
284      - 3rd exchange no longer needed (tested with 24 tiles).
285      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
286      - exch_UV_A-grid readily available (but not yet tested).
287      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
288      (both are no longer needed) in exch_uv: no effect in forward run; but
289       get truncation error differences with adjoint exch.
290    o exch2:
291     - change index-bounds storage (moved from target to local tile,
292       more intuitive this way) ; rename/remove some variables.
293     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
294    
295    checkpoint61a
296    o exch2/matlab-topology-generator:
297      fix bug in index bounds for N-S internal exchange (hard to tell if this
298      had any effect on the solution).
299    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
300      is exceeded
301    o testreport: modify syntax of awk, so that it works also with
302      awk, and not only with nawk and gawk
303    
304    checkpoint61
305    o autodiff
306      Change default for TAF usage by removing argument '-nonew_arg'
307      This changes TAF subroutine argument list (ordering of active var.)
308      Omission of this flag leads to incompatibility w.r.t. TAMC
309      To restore TAMC-compatibility, need following modifs:
310      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
311      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
312      Tested TAF version is 1.9.22
313      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
314    
315    checkpoint60
316    --->>> This is the last checkpoint for which generating the adjoint
317    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
318    --->>> by default.
319    --->>> Future checkpoints will ommit this flag by default.
320    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
321    o pkg/grdchk: Add gradient check to etan0 perturbations.
322    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
323    o pkg/autodiff: more flexibility in zeroadj.
324      model/src: modifying do_oceanic_phys.F accordingly.
325    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
326    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
327      special setup of gmredi for which the adjoint is stable
328      enough for parameter optimization.
329    o bridging the gap between eddy stress and GM.
330      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
331          along with a change in CPP option (now ALLOW_EDDYPSI).
332      -> when using GM w/ GM_AdvForm:
333          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
334          is applied either in the tracer Eq. or in momentum Eq.
335          depending on data.gmredi (intro. GM_InMomAsStress).
336      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
337      The key modifications are in model/src/taueddy_external_forcing.F
338      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
339    
340    checkpoint59r
341    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
342      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
343      fix option to read coriolis(@ cell-corner) from files with CS-grid.
344    o pkg/mnc: add some attributes to standard 1D-coordinate variables
345    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
346      mass points, when using mnc for output
347      - add runtime parameter (missing_value, missing_value_int) to override
348        default (which is the value of getcon('UNDEF'))
349    o pkg/mnc: prepare mnc for the actual use of missing values with the
350      diagnostics package: small fix in mnc_cw_readwrite.template and more
351      initialisation of never used fields
352      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
353      versions
354    o pkg/thsice/thsice_ini_vars.F added default initial values so that
355      thermodynamics sea ice solver does not blow up when some initial fields
356      are missing.
357    o move from external_forcing_surf.F to ini_forcing.F
358      the p-coord. hack consisting in using pLoad to set phi0surf ;
359      update output of tutorial_global_oce_in_p (affected @ truncation level).
360    o Freshen up a bit hs94.1x64x5, notably:
361      remove rotationPeriod and tRef=5*0. (adjoint only), and add
362      exactConserv=.TRUE.
363    o pkg/generic_advdiff:
364      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
365      applies to files where Temperature & Salinity 2nd Order moments are used.
366    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
367      this uses a dynamically allocated internal state data structure
368      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
369      and requires a fortran 90 compiler
370    
371    checkpoint59q
372    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
373       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
374    o Refresh tutorial_global_oce_biogeo, notably:
375      - change bathymetry (put back seamounts in ACC, use hFacs)
376      - change EOS (POLY3 --> JMD95Z)
377      - use Bryan-Lewis vertical diffusivity
378      - use multidimensional advection
379      - remove old virtual virtual in dic pkg, now done through ptracer pkg
380      - change a couple of parameters in dic pkg
381    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
382    o pkg/obcs: change default to OBCSfixTopo = .true.,
383      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
384      - replace "debugMode" with "debugLevel .GE. debLevB"
385    o implementation of TAF directives for gchem,cfc,dic
386    o remove "exp5" (replaced by tutorial_deep_convection).
387    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
388      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
389      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
390      --> changes results in exp4, seaice_obcs
391    o tutorial_deep_convection :
392      update the set-up and increase resolution and domain size ; start
393      from pseudo initial conditions = output at t=120mn in order to see
394      something happening when running testreport.
395    o pkg/seaice: add os7mp as an advection scheme
396                  add check for advection schemes
397                  add a flag for restoring T and S underneath sea ice
398    o pkg/my82: add netcdf-support and diagnostics
399    o thsice pkg:
400      - Now hsMax limits snow height by turning it into ice following
401        flooding scheme (and now conserving energy)
402      - Slight rewriting of the formula in thsice_calc_thick.F
403      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
404      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
405    
406    checkpoint59p
407    o gchem / dic / cfc :
408      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
409      - add new parameter files: "data.dic" & "data.cfc" ;
410      - various re-arrangement in initialisation & header file ;
411      - fix tutorial_global_oce_biogeo for multi-threaded test.
412    o pkg/dic: test for "pickup_dic" file when restarting ;
413      if no pickup-file, can restart with a re-initialised pH (same as it did
414      before) providing pickupStrictlyMatch is set to False.
415    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
416      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
417    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
418      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
419    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
420     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
421       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
422    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
423       scheme to use for vorticty-term ;
424     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
425       (with default selectVortScheme, return to original discretisation)
426     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
427    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
428    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
429      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
430      also fix diagnostics VISCAHW & VISCA4W.
431    
432    checkpoint59o
433    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
434    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
435      move a few statemens out the main loop into separate loops
436    o pkg/shelfice:
437      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
438        (kg/m^2/s), does not break tests, because in verification/isomip,
439        rhoConstFresh=rhoConst (by accident)
440      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
441      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
442        new file model/src/seawater.F, so that they are available for all pkgs.
443      - convert potential temperature into in-situ temperature. This changes the
444        isomip tests => update tests
445    o add a flag writePickupAtEnd (default=true) to be able to suppress
446      writing a pickup at the last timestep
447    o tools/mpack-1.6 :
448      - disable automake (not working) and autoconf (not needed).
449      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
450        also cleaner with much less compilation warnings.
451    o pkg/profiles:
452      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
453      (for "less than 32 characters name" compiler requirement)
454    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
455      conditions that have a different sampling frequency than S/T/U/V obcs
456    o pkg/diagnostics (stats-diags):
457      - fix global Min/Max in case 1 processor get only empty tiles
458    o genmake2: replace (4 times)
459         make genmake_tc_1.o >> genmake_warnings 2>&1
460      with
461         COMM="$CC $CFLAGS -c genmake_tc_1.c"
462         echo $COMM >> genmake_warnings
463         $COMM >> genmake_warnings 2>&1
464      to make genmake2 always see the value of CC as specified in the optfile.
465    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
466      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
467      - modify verification advect_cs test to test SOM-advection on CS-grid.
468    o pkg/ctrl:
469      - Rewrite of ctrl_map_ini_ecco.F,
470        introducing a generic routine (ctrl_map_ini_gen.F).
471      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
472    
473    checkpoint59n
474    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
475      number in dedicate array "hdiag":
476      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
477        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
478      - many small changes (integer format) for large number of diagnostics
479      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
480        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
481    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
482      usingSphericalGrid, this allows to define the rotated grid coordinates
483      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
484      geographical coordinates according to the inverse of the rotation defined
485      by the Euler angles, so that Coriolis parameter and online-interpolation by
486      exf works with the geographical coordinates on XC/YC/XG/YG.
487      Naturally, this feature does not work with all packages, so some
488      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
489      profiles), because there the coordinates are assumed to be regular
490      spherical grid coordinates.
491    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
492      - introduce isopycnal diffusion coefficient control.
493    o tools/adjoint_options:
494      - additional control vector components.
495    o pkg/mnc: have mnc create marginally meaning full coordinate variables
496      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
497    o pkg/mypackage:
498      - add example of read/write pickup for state-var ;
499      - add entry points to the main code for state-vars diags & write-pickup.
500    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
501      transitions for useExfYearlyFields
502      - add new subroutine that determines the file to read from for
503        use*YearlyFields = .TRUE. and .FALSE.
504      - add a verification experiment to global_with_exf that tests
505        useExfYearlyFields with USE_EXF_INTERPOLATION defined
506    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
507      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
508      subroutines (which could be generated from a template, because they are
509      almost identical), for now they are included in obcs_prescribe_read.F for
510      simplicity
511    o pkg/exf:
512      - add a little more diagnostic to exf_interp_read (in analogy to
513        mds_read_field, can be turned off with debugLevel < debugLevA=1)
514      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
515        ugly but fast by unrolling short inner loops, inserting a unroll=8
516        directive in routine lagran, and splitting a loop and making do while the
517        outermost loop (the latter requires the intoduction of index arrays)
518    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
519    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
520      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
521    o verification/seaice_obcs: updated for restart test and latest options
522    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
523      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
524      for now this is only available for the C-grid code and also within
525      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
526    
527    checkpoint59m
528    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
529      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
530    o gad_som : fix flux output (& diagnostics) to have same units as other  
531      advection scheme fluxes (was previously multiplied by deltaT).  
532    o added verification/seaice_obcs both to test seaice open boundaries
533      and to provide an example matlab scrpt for generating them
534    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
535    o pkg/salt_plume: clean up salt_plume_frac.F to
536      remove redundancy in PlumeMethod 1 and 4
537    o pkg/kpp: added saltplume diagnostics
538    o pkg/obcs and pkg/seaice:
539      - do not set uice and vice to zero when OB*icefile are unspecified
540      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
541      - moved seaice tracer obcs after call to seaice_growth
542    o pkg/salt_plume: added various options for salt plume depth
543      criterion and for vertical distribution of the salt
544    
545    checkpoint59l
546    o pkg/ptracers: new version of ptracers pickup:
547      read meta file and write only fields which are needed to restart.
548      ( same logic as main pickup file ; also using pickupStrictlyMatch )
549    o pkg/seaice:
550      - add timescale for melting due to warm mixed layer as a means of
551        setting SEAICE_availHeatFrac more conveniently
552      - add a CPP-flag/runtime parameter check for flooding algorithm
553      - reformulated availHeat in seaice_growth.F to be independent of AREA
554    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
555      unit changes
556    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
557    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
558      SX vector computer.
559    o pkg/seaice:
560      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
561        seaice forcing fields can now be read only through pkg/exf
562      - removed some unused halos
563    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
564    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
565      or U/VICE from U/VWIND before computing U/VSTRESS
566    
567    checkpoint59k
568    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
569      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
570    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
571      all experiments pass when compile with un-initialised var. checking option.
572    o added pkg/salt_plume
573    o script to test restart (for now, in MITgcm_contrib/jmc_script)
574    o pkg/seaice: new read/write pickup version.
575      read meta file and write only fields which are needed to restart.
576      ( same logic as main pickup file ; also using pickupStrictlyMatch )
577    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
578    o lab_sea.hb87: modify the domain & update output.hb87.txt :
579      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
580      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
581      process. Fixed here by closing the domain at the Northern boundary.
582    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
583    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
584      a set of consecutive levels in/from a 3-D array.
585    o pkg/ptracers:
586      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
587      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
588    
589    checkpoint59j
590    o in pkgs: dic, obcs, offline, rbcs:
591      standard way to compute coeff. for time interpolation between 2 time reccords
592      which retains full precision (& make results less dependent on compiler).
593      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
594    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
595      packages instead of reading ice cover and wind speed separately
596    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
597     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
598      to allow to compile customized code before the update)
599    o cleaning-up:
600      - fix CPP instruction syntax in pkg/obcs
601      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
602        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
603      - fix some threads issue in IO parts.
604    o pkg/dic:
605      - add tons of "_d 0" (--> much better testreports !)
606       and then update outputs of tutorial_global_oce_biogeo
607    o pkg/mom_fluxform:
608      add a special version of momentum advection intended to conserve momentum
609      next to a bathymetry step or a coastline edge. (default = off = #undef)
610    o new read/write pickup version:
611      - for now, only implemented for main (mdsio) pickup file.
612      - write out only what is needed to restart; merge pickup_nh , pickup_ph
613        and main pickup together.
614      - read meta file; read only what is needed to restart; stop if a field
615        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
616        if it make sense (even if the restart is not perfect).
617      - if no meta file, assume that pickup to read corresponds exactly to
618        a pickup that would currently be written.
619      - read pickup written in the old format (until checkpoint59i) if it
620        recognizes an old meta file (no field-list).
621      - add a meta file in exp. which starts from a pickup: 2 cases:
622        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
623         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
624        b) a meta file describing the content of the associated pickup file
625         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
626    o pkg/mdsio & pkg/rw:
627      - new routine to read a meta file ; new set of routine to read
628        Multiple-fields file (with meta file).
629    o added open boundary conditions capability for seaice
630        HSNOW, HSALT, UICE, and VICE
631    
632    checkpoint59i
633    o adjoint:
634      * fix multiDimAdvection adjoint
635        (partial recomputation problem by TAF for fVerT(:,:,kDown)
636        and comlev1 size definition (maxpass vs. max. number of tracers)
637      * verification/global_ocean.90x45x15 adjoint now tests
638        NLFS and multiDimAdvection using DST3 (=30)
639      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
640    o pkg/kpp: add "_d 0" to real constant (if missing);
641      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
642      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
643    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
644      for internal parameters related to restart process (formerly from PARAMS.h)
645      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
646    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
647      as argument. (only atm2d & obcs write_pickup have not yet been updated)
648    o pkg/monitor:
649      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
650      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
651      - account for deep Atmosphere factor and density factor (anelastic)
652    o added open boundary conditions capability for seaice HEFF and AREA
653    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
654      thermodynamics
655      - requires a little reorganization, which affects the testreport results
656        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
657        so that now the conservative form is tested
658      - add a few comments
659    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
660    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
661    o add new diagnostics to seaice: advective, diffusive fluxes (only for
662      multidim-advection, for scheme 2 they are not filled) and transports,
663      thermodynamic growth rates
664    o change units of EmPmR (inside the code, + within coupling interface)
665      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
666      Affects results @ truncation level (cg2d match) and update output of
667       experiments: lab_sea(6), global_ocean.90x40x15(10),
668      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
669      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
670      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
671      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
672    
673    checkpoint59h
674    o pkg/exf:
675      - improve vectorization by moving if-statement out of loops in
676        exf_mapfields, exf_radiation
677      - exf_bulkformulae.F: introduce 2D fields and vectorize code
678    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
679    o testreport:
680      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
681        monitor & update offline_exf_seaice exp. output.
682      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
683    o pkg/seaice:
684      - bug fix in the evp solver: boundary conditions were affected be
685        masking of zMax/zMin (changes results)
686      - minor bug fix in boundary conditions in seaice_calc_strainrates
687        (changes results for no_slip)
688      - seaice_lsr.F: make interpolation of eta dependent on boundaries
689      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
690      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
691        stress formulation and no-slip boundary conditions
692    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
693      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
694    o pkg/seaice: a first HSALT time stepping equation has been checked in
695    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
696      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
697      without requiring DO-IF statements
698    o pkg/thsice:
699      use continuous power-law function for partition of energy between lateral
700      melting/freezing and thinning/thickening ; old code using step function
701      still available with #undef THSICE_FRACEN_POWERLAW
702      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
703    o testreport: change AD testing : check against results/output_adm.txt
704      using same scripts as for forward test.
705    
706    checkpoint59g
707    o adjoint testing: in preparation for changing testreport:
708      - output format: cost and grad written on separated lines
709      - ad output results in directory "results" (instead of "results_ad")
710    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
711    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
712    o pkg/ecco: allow user defined cost function contributions
713    o testreport:
714      Allow to choose (per experiment) the list of tested output variables
715       and the main variable (used to issue a pass/FAIL ) ;
716      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
717      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
718      Also modify printing of summary:
719       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
720       b) echo the list of tested variables in the individual summary.txt of
721          each experiment.
722    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
723      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
724      (but still depend on the tile decompostion of the domain).
725    o pkg/seaice: change a discretization detail to make the B-grid code
726      "more symmetric". This change is likely to remove all "ridges/leads" that
727      where quasi-aligned with the grid in B-grid solutions. It may also be
728      the solution to the stress coupling issues with the B-grid.
729    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
730      remove .cvsignore from input dir. (since testreport no longer run here).
731    o pkg/thsice:
732     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
733     - fix reshaping of sea-ice just after advection:
734       melt all the ice only if ice-volume is too small.
735     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
736       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
737     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
738    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
739      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
740    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
741      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
742      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
743      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
744      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
745      -> update output.txt
746    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
747     this affects truncation error: -> update output.txt of exp:
748      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
749      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
750    
751    checkpoint59f
752    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
753    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
754      a bounded range (in forward mode)
755    o pkg/ecco, ctrl, autodiff and mom_common:
756     internal parameter controls, completements of implementations
757    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
758    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
759      (not seem any difference in testing results).
760    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
761       at face corners.
762    o pkg/generic_advdiff:
763     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
764      loop range indices for computing vertical advection tendency
765      and do the calculation in the interior only (no overlap) ;
766      for now, only implemented for SOM advection (to save CPU time).
767     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
768    o exch2 adjoint
769      First set of changes:
770      - add exch2 hand-written adjoint templates
771      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
772        This will require cleanup in pkg/autodiff/*.F
773        (changed routines currently kept separate in verif. code/)
774      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
775        that used to hide exch2 or cubed-sphere specific code
776        (commented via 'cph-exch2')
777    o pkg/seaice
778      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
779    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
780       output of global_ocean.cs32x15.thsice .
781    
782    checkpoint59e
783    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
784      for B-grid vector (not yet tested) and C-grid vector (<- only used
785      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
786    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
787      (#ifdef ALLOW_SALT_PLUME)
788    o gather_2d/scatter_2d: removed halo regions
789    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
790      scheme and the corresponding test case (under front_relax dir). For now,
791      only available with Skew-flux form and not yet tested in realistic set-up.
792      adjoint: store directives updated, but gradient checks deteriorated,
793      so maybe GM/Redi adjoint is now broken.
794    o seaice adjoint
795      * add AREA, HEFF, HSNOW as control variable
796        (should not change lab_sea results)
797      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
798    o pkg/seaice:
799      * added computation of saltFlux in seaice_growth;
800        For time being, sea ice salinity is assumed constant
801        contribution of snow flooding to freshening of sea ice is neglected.
802        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
803        defaults to 0.0 in order to maintain backward compatibility.
804        Typical values for SEAICE_salinity are 4 to 10 g/kg.
805      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
806      * added SEAICE_availHeatFrac, which specifies fraction of surface level
807        heat content used to melt or grow ice
808      * commented out cap of HICE: it helps keep ice thinner
809      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
810      * applied OBCS T/S mask to HEFFM sea ice mask
811    
812    checkpoint59d
813    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
814     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
815     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
816    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
817     and change default value of parameter "GM_Small_Number";
818     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
819       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
820       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
821    o pkg/ecco: cost function when applying pkg/smooth to controls
822    o pkg/ctrl: add forcingPrecond run time parameter
823    o pkg/seaice:
824     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
825     - fix bug in metric terms of u-equation in LSR solver (implicit part),
826       changes verification/lab_sea
827     - rearrange implicit part of u-equation in LSR solver to make it easier to
828       read, understand, and debug. This causes changes at the truncation level.
829     - fix (serious) bug in the boundary conditions (sign error in the implicit
830       part) of the LSR solver. Changes all LSR results.
831     - fixed problem with HSNOW initialization to avoid thick snow when AREA
832       is initilized with small values - does not change lab_sea results.
833     - added HsnowFile initialization capability
834    o pkg/smooth: addition to model/src and pkg/ctrl so allow
835     initialization of pkg/smooth and application to control vector
836    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
837    o dependencies: pkg/profiles requires pkg/cal
838    o pkg/profiles:
839     - added option ALLOW_PROFILES_GENERICGRID
840         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
841         that interpolation information (grid points and coefficients) is provided
842         within the netcdf input files.
843         -> sample matlab scripts can be found in MITgcm_contrib/gael
844         that allow you to prepare netcdf input files.
845     - also modified: cleaner include statements, cleaner error print statements,
846       cleaner stops when error, and more tests of the netcdf input files consistency.
847    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
848    o pkg/seaice:
849     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
850       requires a new routine: seaice_diagnostics_fill.F
851     - make sure that seaice does not move if not forced (pressure replacement
852       method, Hibler and Ip, 1995), changes results
853     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
854     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
855       It is turned off by default (=-1.), because it changes the results.
856     - make it possible to read AREA from a file, too.
857    
858    checkpoint59c
859    o add S/R and diagnostics for oceanic mixed-layer depth
860    o move GMRedi call after all vertical mixing schemes (including KPP)
861    o pkg/thsice:
862     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
863      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
864    o pkg/obcs:
865     - bug fix for balance code
866    o pkg/seaice:
867      - allow values of SEAICE_elasticParm > 1
868      - add new parameter SEAICE_evpTauRelax as an alternative
869        to SEAICE_elasticParm
870      - make lsr boundary conditions free slip (by default), changes result
871      - add code for no slip boundary conditions for lsr
872      - set minimum of zeta to zero (and not 4e8) (changes results)
873      - add a cap on AREA after advecting AREA if seaice_growth is not called
874    o change calculation of Visbeck K:
875      - no longer depend on tapering scheme; instead, compute slope (limited
876        by GM_maxSlope). this is equivalent to what was comuted before with
877        clipping or linear tappering.
878      - fix vertical averaging (wrong by 1/2 level)
879      - leave the old version (but will not be maintained) within
880        #ifdef OLD_VISBECK_CALC / #endif
881      - update output of exp. ideal_2D_oce
882    o change error catch in calc_r_star to improve vectorization
883    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
884      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
885    o adjoint:
886      Re-organized adjoint checkpointing according to Matt Mazloff
887      (but with modifs/completions/cleanups)
888      Storing is now bundled into large arrays to optimized I/O
889      (and second step in cleanup of the_main_loop)
890    
891    checkpoint59b
892    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
893      - export/import (between ocean & coupler) fields needed for ocean DIC.
894    o pkg/seaice:
895      - get rid of three more exchanges seaice_calc_viscosities (required
896        different loop boundaries in seaice_lsr and seaice_ocean_stress)
897      - bug fix in seaice_ocean_stress (update of lab_sea required)
898      - reduce loop boundaries to necessary minimum also in seaice_evp
899      - go back to the old way of computing deltaC/Z as the adjoint likes that
900        better
901    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
902      passive tracer to an Age Tracer) + update output.txt
903    o pkg/exf:
904      - implement A-grid / C-grid selection for wind-stress input files.
905      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
906      for now, in exf_bulk_largeyeager04.F only :
907      - change implementation for case where windspeed + 2. components wind-stress
908        are read-in. AND use rhoConstFresh to convert evap.
909    o pkg/seaice:
910      - use correct EXCH_UV for wind-forcing (on A-grid).
911      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
912        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
913    o pkg/exf:
914      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
915      EXF_INTERPOLATION:
916      - merge global_with_exf/code version of exf_interp_read.F
917        to the main code ;
918      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
919        reading the file ; Important: This options needs to be defined to recover
920        previous code.
921        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
922      - no longer loose real*8 precision along the way when using exf_iprec=64.
923    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
924      - change discretisation of evp-solver in order to avoid another exchange
925        (changes lab_sea) and clean up a little
926      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
927        help the adjoint (this also changes the results slightly)
928      - add a few "_d 0" where they had been missing in seaice_evp.F
929      - cleaning up: remove unused seaice_calc_rhs.F
930    o pkg/exf: some cleaning-up:
931      - change various "constants" into runtime parameters
932      - cleaned-up Large&Yeager04 routine which should eventually
933        replace exf_bulkformulae.F (changed names of S/R and CPP)
934        and merged various ALLOW_ATM_WIND options
935     only used with thsice pkg (in thsice_get_exf.F):
936      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
937        which are used when useStabilityFct_overIce=TRUE (= the default)
938      - change default values of ice & snow emissivity and scale downward LW
939        by ice & snow emissivity.
940    o pkg/thsice:
941     fix few little problems, in thsice_calc_thickn.F:
942      - growth vertically (and not laterally) if iceFrac == iceMaskMax
943      - melt only laterally if hIce < hThinIce (as the comments say)
944      and in thsice_extend.F:
945      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
946      - start to form ice as soon as the minimum ice-volume is reachable.
947     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
948      and cpl_aim+ocn
949    o pkg/kpp
950     - move computation of surface related input fields to KPP into a new
951       subroutine kpp_forcing_surf.F
952     - remove wrong (within bi,bj loops) EXCH calls.
953     - little cleaning (add argument myThid in last position, cvs header ...)
954     - for now, fix conservation problem by exchanging KPPviscAz (may not
955       be the best fix)
956    o pkg/seaice
957     - check for inconsistent evp parameter/cpp-flag combination
958     - remove leftover errIO flat for obsolete name list error handling
959    o OpenAD
960     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
961    
962    checkpoint59a
963    o pkg/seaice: some parameter clarifications and a little bit of clean up
964    o pkg/thsice: rename run-time parameters:
965       himin       -> hIceMin
966       himin0      -> hThinIce
967       hihig       -> hThickIce
968       i0          -> i0swFrac
969       transCoef   -> bMeltCoef
970       frac_energy -> fracMelting
971      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
972       with default values (for now) that do not change the results.
973      remove old version of thsice vars advection in pkg/seaice.
974    o in FFIELDS.h:
975      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
976      - make pLoad & sIceLoad always available (but still only used if
977         ATMOSPHERIC_LOADING is #define).
978    o pkg/kpp: replaced _KPP_RL with _RL
979    o bug fixes for vertical diffusivity computations when both KPP and
980        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
981        are no longer updating the vertical diffusivity array
982        (passed as argument) but are (re-) setting those arrays.
983    o pkg/seaice: fix bug in evp solver, while doing that
984      - change (improve?) discretization of stress computations for both
985        cgrid-lsr and evp solver
986      - add a new routine to compute strain rates
987      - the above changes lab_sea results
988      - add no slip conditions for evp solver (off by default), lsr-version
989        may follow
990      - fix exchange for shear at Z-points (does not change lab_sea)
991      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
992        (to force the user to pick a time step since there is not "safe" way
993        of choosing it)
994      - add principal stress diagnostics
995      - rearrange fields for evp a little to avoid having to call a: too many
996        exchanges and b: exchanges for stress trensor components which we do
997        not have.
998      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
999        of evp, complete rewrite for lsr case (latter is does not yet work
1000        in all cases)
1001    o pkg/kpp: add code to have mixing in shelf ice caverns
1002      - add myThid to all kpp routines (long overdue)
1003    
1004    checkpoint59
1005    o pkg/exf:
1006      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
1007        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
1008      - move exf header files from lower_case.h to UPPER_CASE.h ;
1009        add missing cvs Header & Name
1010      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
1011      - add namelist param. selectStressGridPosition, exf_monFreq
1012      - retire many _CLIM routines, and remove data.exf_clim
1013        + params moved to data.exf
1014        + climsst, climsss now handled by exf_set_gen, i.e.
1015          climss?period=0 refers to constant field,
1016          climss?period=-12 to monthly forcing
1017      - split up namelists in data.exf
1018    o pkg/seaice:
1019      - remove seaice_exch and seaice_exch_uv
1020      - remove superfluous exchange of theta
1021      - add myThid to seaice_budget_ocean/ice
1022      - add new interface for atmospheric wind forcing (C-grid only)
1023        + new routine
1024        + two new field (taux, tauy for stress over ice)
1025        + removed one global field (DAIRN) for C-grid case only
1026    o pkg/thsise
1027      - 2nd set of modifs for thsice adjoint in conjunction with exf
1028    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
1029    
1030    checkpoint58y_post
1031    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
1032      vertical diffusivity, similar to that in MOM4; turned on using
1033      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
1034      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
1035    o Added capability for 3D specification of background vertical diffusion
1036      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
1037      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
1038      "data" file that contains the 3D vertical diffusivity coefficients.
1039    o ice dynamics (pkg/seaice) with thsice thermodynamics:
1040      - add code within pkg thsice to advect & diffuse sea-ice fields
1041      similar to (and will replace) what has been added in  seaice_advdiff.F,
1042      but: - conserving Mass, Heat & Salt.
1043           - better when using non-linear advection scheme (not yet fully tested)
1044           - can also be used in atmospheric set-up (for now, only the diffusion).
1045    
1046    checkpoint58x_post
1047    o IO option for global-file compact format:
1048      - add options when generating topology (utils/exch2/matlab-topology-generator)
1049      - add I/O capability (pkg/mdsio).
1050      - adapt utils/matlab/rdmds.m to read this format.
1051      for now long-line format not yet supported by pkg/mdsio (& exch2).
1052    o shelfice: add a few diagnostics
1053
