Re: [netcdfgroup] "reboxing," or 3D regridding

Tom,

1) Yes, The file - along with many others - is located at:
https://modave.svn.sourceforge.net/svnroot/modave/cdat_data/

2) Tons of - OK... a few - examples are in:
https://modave.svn.sourceforge.net/svnroot/modave/cdat_tests/

The example related to the one on the web site is:
mpirun -np 2 python testEsmf3DSalinity.py
But any of the testEsmf3D*.py should help and don't need to be run with mpi.
Let know if I can of further assistance. Maybe off list, kindig@xxxxxxxxxx...
All that being said, I think ncl has also a quite nice implementation of ESMF but I am not sure if they have fully implemented it yet.

[ESMF] has a python module [as well as] fortran and c interfaces.



You can also access it through uv-cdat (http://uvcdat.llnl.gov/)

I need to "rebox" voxels[, but] ESMF only seems to work with data
that's attributed to a 2D grid,


doh! I was looking @

http://www.ncl.ucar.edu/Applications/ESMF.shtml

rather than the ESMF examples @

See the Tech-X website for a uv-cdat python example.

Thanks! The latter example esp looks helpful. Two more questions:

1. The Regrid3D example uses data with filename=

so_Omon_GISS-E2-R_historicalNat_r5i1p1_185001-187512_2timesteps.nc

    Is that available somewhere? (It did not google.) Might be useful for
    folks "playing along at home."

2. I gotta rewrap my head around the python/numpy way of doing things.
    Can you recommend any user-level ESMF tutorials oriented toward this
    relatively low-level task (regridding)? Most of what I see (e.g. @

http://www.earthsystemmodeling.org/users/getting_started.shtml

    ) seems more oriented toward designing/developing for a full-blown
    ESMF-based model, i.e., substantially conceptually more high-level.

http://www.earthsystemmodeling.org/esmf_releases/non_public/last/regridding_status.html

    is more like what I need, though it doesn't seem to point to
    code examples.

thanks again, Tom Roche <Tom_Roche@xxxxxxxxx>
