Re: [gembud] gdgrib interpolation


GEMPAK enables computation of quantities using grids of different
projections and/or output grid projections using a combination of
bi-linear interpolation and area average (when one output grid box
contains approximately four or more input grid boxes). Aside from
creating output as in GDGRIB, computation
on multiple input grids of different navigations is possible in plotting
programs as well as GDDIAG.

The GDGRIB documentation states that the gempak data is "horizontally interpolated" onto the new user-specified grid, where the user can specify the projection and horiz grid spacing. Does anyone know how this horizontal interpolation is done?

Thanks for any info,
