Native ETA Grid in GRADS

Sorry, I misunderstood and don't have such pdef file. Perhaps the
following source code could be modified?
http://nomad1.ncep.noaa.gov/DOC/g218.f
Is the dashed line the "native" grid, or a "parent" grid? It looks like
the ETA-90km grid. Is ETA output at a 12-km resolution available to the
public either in real-time or in an archive for the coverage indicated by
the dashed line? Residing in northern BC, I'd be interested in such data...
Thanks,
- Brendan
