Gerry,
After completing the pending action items, we will be able to
move forward with suggestions for additional data sets. The
GRIB1 to GRIB2 transition has been one that has been slow
on several fronts, but once complete will free up bandwidth
on CONDUIT as well as diskspace at the source, so this
is an important step in moving CONDUIT forward.

Chiz,
What are the chances of seeing NAM AWIP grid 221 via CONDUIT?
Is this a discussion topic (again) for AMS?
Thanks, Gerry
