7    o eesup and pkg/mdsio: ALLOW_WHIO
8    
9      Option to write/read 2D fields to files including tiles halos.
10      The main purpose is for adjoint related "tape I/O".
11      The secondary purpose is for debugging phases.
12    
13      A word on those rather specifically intended purposes.
14      The code was meant to be stripped down to the bare minimum.
15      Typically, there is a unique and basic mapping to the global
16      buffer (tile by tile, then proc by proc, then level by level), and
17      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
18      meant to generate user friendly outputs of various shapes and forms.
19      Rather it is intended, for the knowledgeabale developers,
20      to be largely independent of the many mdsio options, to allow
21      outputs of tiles+halos in debugging phases and in adjoint runs,
22      and to allow some flexibility in tuning (adoint) I/O depending on each
23      file system behavior. With regard to tuning, most of the potential knobs
24      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
25      to specify directories, to specify the typical size of I/O calls, etc.)
26      are not yet included, and will be added if they prove useful.
27    o pkg/seaice:
28       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
29    o pkg/seaice:
30       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
31       code (seaice_budget_ice_if.F) which enable to recover old standard
32       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
33       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
34    o model/src (rStar):
35       use simple average (not area weighted) of rStarFac at U,V point when using
36       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
37       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
38    
39    checkpoint62k (2010/09/17)
40    o adjoint
41       * changed verification/global_ocean.cs32x15 ; adjoint now tests
42         Adams-Bashforth 3 + NLFS + RSTAR
43       * some more modifs required for ECCO-GODAE v4
44    o pkg/seaice
45       add SEAICE_AGE_VOL option to use volume instead of area for
46       integrating SEAICE_AGE
47    o model/src:
48       first check-in of sigma & hybrid-sigma coordinate code ; also includes
49       non-linear free-surface parts ; but pressure-gradient not yet coded.
50    o pkg/ptracers:
51       option for ptracer to convert Salt Relax into additional EmP.
52        tested in exp. global_ocean.90x40x15.dwnslp (update output)
53    
54    checkpoint62j (2010/08/25)
55    o pkg/ggl90:
56       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
57    o pkg/dic: car_flux.F, phos_flux.F
58      - reduce number of exp-calls in order to improve performance
59      - clean up a little (replace fields by their macros, etc., fix
60        typo in CPP-flag)
61  o pkg/ggl90: minor changes  o pkg/ggl90: minor changes
62    - GGL90diffKrS was removed --> always use GGL90diffKr    - GGL90diffKrS was removed --> always use GGL90diffKr
63    - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV    - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
64    - hack of mxlMaxFlag=2 --> ensure mixing between first and second level (commented out for now)    - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
65        (commented out for now)
66    - change in max/min operations to ensure that smoothing is ok    - change in max/min operations to ensure that smoothing is ok
67    - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)    - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
68    - always use diffKrNrT as background profile (i.e. never use diffKr field)    - always use diffKrNrT as background profile (i.e. never use diffKr field)
