wgrib2: -spatial_proc


Product Definition Template 4.15 is used to describe spatial processing of a forecast or analysis. For example, you interpolate a model grid to an output grid. For some fields you may use nearest neighbor interpolation and for other fields you may use bilinear interpolation. The North American Regional Reanalysis used both types of interpolation for surface and near surface fields. Another use of PDT 15 is in aviation. You might want the maximum clear air turbulence when the interpolate from a fine grid to a coarse grid.

The option, -spatial_proc, prints the spatial properties that are encoded in PDT 4.15. This output is part of the of the standard inventory, -s.
