Tom,I am not sure if this will help, but here is the section on creating a grid. You should be able to generate a 3D grid of uniform elements over which you can regrid (rebox) from one 3D grid to another. I think reboxing is the same as regridding if the grid in question is 3D. Is that right?

However I'm not seeing anything to indicate that ESMF does 3D: am I missing something?Just to clarify: I need to "rebox" voxels. ESMF seems to do a 3D interpolation in order to "regrid" pixels, which it defines (rather well) as http://www.earthsystemmodeling.org/esmf_releases/public/ESMF_5_2_0rp1/ESMF_refdoc/node3.html#SECTION03020000000000000000Regridding, also called remapping or interpolation, is the process of changing the grid that underlies data values while preserving qualities of the original data....The regridding occurs in 3D to avoid problems with periodicity and with the pole singularity.But ESMF only seems to work with data that's attributed to a 2D grid, rather than data attributed to a 3D grid ... unless I'm missing something. your assistance is appreciated, Tom Roche <Tom_Roche@xxxxxxxxx> _______________________________________________ netcdfgroup mailing list netcdfgroup@xxxxxxxxxxxxxxxx For list information or to unsubscribe, visit: http://www.unidata.ucar.edu/mailing_lists/
