I'd like to re-grid my UPP Grib2 output data. How can I process it to another grid or projection?
For re-gridding Grib2 unipost output, the wgrib2 utility can be used. Complete documentation on grid specification with examples of re-gridding for all available grid definitions can be found at:

An example of how operations use wgrib2 to interpolate to a lat-lon grid is given in the "Examples of wgrib2" section of the UPP User's Guide for v4.1.
