20020711: 20KM ETA


The ETA grids 215 (20km) grids on the NOAAPORT broadcast
are primarily surface and boundary layer quantities (generally
on pressure layers above the ground). At this time, the SBN does
not broadcast height grids on the 20km grid.

The absolute vorticity grid is the only quantity
shipped at standard pressure levels.
