5      ==============================      ==============================
6    
7    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
8      and portions thereof.  See read_cs.txt for description and examples.
9    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
10      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
11      following the great-circle arc between those 2 points.
12    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
13      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
14    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
15     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
16     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
17     - still needs work (not working with some options ; efficiency to improve)
18       and serious testing.
19     - use this scheme for temperature & salinity in 2 advection test exp.:
20       advect_xy & advect_xz, respectively.
21    
22    checkpoint58u_post
23    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
24    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
25    o testreport: add option "-skipdir" to skip some test.
26    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
27      momentum calculation.
28    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
29    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
30      remove checkpoint.F and the_correction_step.F (no longer used);
31      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
32    o add option (linFSConserveTr) to correct for tracer source/sink due to
33      Linear Free surface
34    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
35    o pkg/thsice: fix reading mnc-pickups
36    
37    checkpoint58t_post
38    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
39    o pkg/mdsio:
40     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
41       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
42       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
43     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
44     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
45       either MDS_READ_FIELD or MDS_WRITE_FIELD )
46     - new S/R (to replace MDSWRITEMETA), which allows to write more
47       informations (variable names, time ...) to meta files.
48     - modify rdmds.m to give back the meta file content.
49    o pkg/diagnostics: change vertical interpolation to be safer, and more
50       flexible (define p-levels to interpolate to in data.diagnostics);
51      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
52       diagnostic pointer.
53    o pkg/seaice: more cleaning up of seaice_growth, added many comments
54    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
55    o fix multi-category seaice:
56     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
57       SEAICE_MULTICATEGORY
58     - fix short wave heat flux
59    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
60       and allow to use EVP solver. Change forward lab_sea: test both EVP
61       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
62    o Initial check-in of lab_sea adjoint
63      (very similar to natl_box_adjoint/code_seaice)
64      * used C-grid and EVP solver
65      * used KPP, GM/Redi
66      * uses inAdExact=.TRUE.
67      * gradient checks fail for both ADM and TLM
68        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
69        f.d. gradients actually seem more problematic than ADM, TLM gradients;
70        issue is related to forward mismatch between g77 an ifort
71    o pkg/seaice: overhaul of thermodynamics
72     - growth.F and groatb.F are replaced by new routine seaice_growth.F
73     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
74     - move a few global fields out of SEAICE.h into seaice_growth.F and
75       make them 2D (FICE/QNETO/ ...)
76     - remove FO (it is the same as QNETO)
77     - introduce a few local fields to avoid modifying external fields such
78       as atemp, etc.
79    
80    checkpoint58s_post
81    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
82      changed exf_set_gen.F so that
83        genperiod=0 means input file is one time-constant field and
84        genperiod=-12 means input file contains 12 monthly means
85    o CG2D: use pre-computed solver main-diagonal (stored in common block);
86      this affects truncation error ; generate new output file for exp. which
87      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
88        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
89        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
90        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
91        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
92        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
93    o start implementation of deep-atmosphere and anelastic formulation
94    o verification: remove 2nd copy of input files and use script "prepare_run"
95      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
96  o mom_common/vecinv/fluxform: fix a few initialisation isssues  o mom_common/vecinv/fluxform: fix a few initialisation isssues
97  o profiles: fix for multithreaded case  o profiles: fix for multithreaded case
98
