This .zip includes a sample script for regridding the transportable fraction
file (XPORTFRAC) used to adjust afdust emissions after SMOKE is run.

The sample script is called regrid_12EUS1.csh, and uses an input file called 
xportfrac.8vars.beld3.4kmgrid.ncf, which is also included in the .zip.
The gridded xportfrac file included in the .zip covers most of North America at
4km resolution.

The script uses the spatial allocator to regrid the XPORTFRAC to another grid.
The spatial allocator is available for download here:
