[gradsusr] sflux (weasdsfc) with pgrb2.0p25 (tmpprs), lterp or lost hope?

[Jeff Duda]

You can interpolate between ANY two grids as long as both are defined
somehow (i.e., in the control file).

define newfield = lterp(snow006,mor006)
OR
define newfield = lterp(mor006,snow006)
should do what you want, unless you want the output on a specific grid. In
that case, use which ever field that's on the grid you want to interpolate
to as the destination grid (second argument).
