4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
8    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
9       update lab_sea.lsr & lab_sea.salt_plume results
10    o pkg/seaice:
11      Major overhaul of the LSOR solver: change discretization from original
12      finite differences to finite volume. The old routine is still in the
13      file seaice_lsr.F and can be turned on with the CPP-flag
14      SEAICE_OLD_AND_BAD_DISCRETIZATION
15      Along with this change, the discretization of the strain rates is changed.
16      The same flag turns on the old discretization in seaice_calc_strainrates.F
17      All verification experiments with seaice are affected (except for
18      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
19      results by setting the above flag.
20      Further changes involve changes in defaults:
21      - ALLOW_FLOODING is defined and turned on by default
22      - SEAICE_advSnow = .true. is now the default
23      - SEAICE_advSalt = .true. is now the default
24      - SEAICE_advAge  = .true. is now the default
25      - SEAICE_clipVelocities  = .false. is now the default
26                                         (as per J. Zhang's recommendation)
27      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
28        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
29      - seaice_growth: replace computation of UG by a simple copy from wspeed
30    
31    checkpoint61k
32    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
33      seaice_lsr: fixed a few metric terms,
34                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
35                  add more debugging diagnostics
36      seaice_evp: removed superfluous many metric terms of FV discretization
37                  of stress divergence
38                  affects lab_sea, lab_sea.hb87
39      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
40                  of stress divergence for non-evp solver
41                  (this part is not tested anywhere)
42      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
43                  they were effectively only half slip
44                  affects lab_sea.hb87
45      updated all relevant verification experiments (except lab_sea//output_adm.txt
46        which was left over, but fails at level 7 & 6)
47    
48    checkpoint61j
49    o pkg/seaice: turn a few hard wired parameters into run time parameters
50    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
51      time in seconds as promised by the usints in seaice_monitor and exf_monitor
52    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
53      that are not cubed-sphere grids
54    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
55    o pkg/ctrl:
56      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
57    o non-hydrostatic (calc_gw.F):
58      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
59      update output of exp. global_ocean.cs32x15.viscA4
60    o remove backward compatibility for thetaMin,phiMin
61      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
62  o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the  o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
