7    o experiment fizhi-cs-aqualev20:
8      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
9      and generate new output. Note: new output is much closer to the old
10      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
11      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
12    o pkg/fizhi:
13     - change to avoid indices going deliberately over array-bounds
14     - remove unnecessary MPI stuff
15     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
16     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
17       does not go over array-bounds and therefore returns reliable output.
18     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
19       this S/R has 4 output arguments, which are used inside "get_alarm";
20       when it is called with the same variable "ndum" in place of several
21       output arguments, this produces weird side effect inside "get_alarm"
22      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
23       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
24       address) and produces error.
25    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
26    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
27       update lab_sea.lsr & lab_sea.salt_plume results
28    o pkg/seaice:
29      Major overhaul of the LSOR solver: change discretization from original
30      finite differences to finite volume. The old routine is still in the
31      file seaice_lsr.F and can be turned on with the CPP-flag
32      SEAICE_OLD_AND_BAD_DISCRETIZATION
33      Along with this change, the discretization of the strain rates is changed.
34      The same flag turns on the old discretization in seaice_calc_strainrates.F
35      All verification experiments with seaice are affected (except for
36      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
37      results by setting the above flag.
38      Further changes involve changes in defaults:
39      - ALLOW_FLOODING is defined and turned on by default
40      - SEAICE_advSnow = .true. is now the default
41      - SEAICE_advSalt = .true. is now the default
42      - SEAICE_advAge  = .true. is now the default
43      - SEAICE_clipVelocities  = .false. is now the default
44                                         (as per J. Zhang's recommendation)
45      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
46        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
47      - seaice_growth: replace computation of UG by a simple copy from wspeed
48    
49    checkpoint61k
50    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
51      seaice_lsr: fixed a few metric terms,
52                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
53                  add more debugging diagnostics
54      seaice_evp: removed superfluous many metric terms of FV discretization
55                  of stress divergence
56                  affects lab_sea, lab_sea.hb87
57      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
58                  of stress divergence for non-evp solver
59                  (this part is not tested anywhere)
60      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
61                  they were effectively only half slip
62                  affects lab_sea.hb87
63      updated all relevant verification experiments (except lab_sea//output_adm.txt
64        which was left over, but fails at level 7 & 6)
65    
66    checkpoint61j
67    o pkg/seaice: turn a few hard wired parameters into run time parameters
68    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
69      time in seconds as promised by the usints in seaice_monitor and exf_monitor
70    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
71      that are not cubed-sphere grids
72    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
73    o pkg/ctrl:
74      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
75    o non-hydrostatic (calc_gw.F):
76      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
77      update output of exp. global_ocean.cs32x15.viscA4
78    o remove backward compatibility for thetaMin,phiMin
79      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
80    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
81      interpolated wind field not only for curvilineargrid=.true., but also
82      for a rotated grid (rotateGrid=.true.)
83    o pkg/exf: add capability to bypass interpolation for runoff
84      by setting yet another CPP-flag
85    o eesupp/src, B-grid exchange:
86      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
87    o autodiff
88      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
89      allows to switch to single-prec common blocks;
90      corresponding switch occurs in tamc.h, integer isbyte
91      TAF store directivs "byte" and "kind" seem equivalent;
92      Most tamc.h have been updated correspondingly.
93    
94    checkpoint61i
95    o autodiff:
96      fix autodiff_sore/_restore indices for obcs
97      (spotted by I. Hoteit, M. Mazloff)
98    o pkg/autodiff, pkg/ctrl:
99      Add flag to reduce all tapelev I/O to single-prec.
100      In data.ctrl set
101        doSinglePrecTapelev = .TRUE.
102    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
103      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
104    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
105      real fresh water flux (not yet)
106    o pkg/mdsio & rw:
107     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
108     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.

117     - change vertical position in initial condition, from index to depth [m].
118     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
119       (easier to get to a curvilinear grid) ; delX,delY no longer used.
