Hi Glenn,

Having come in on this conversation part way through I'm hoping my 
impression isn't way off, let me know if it is. My one sentence summary 
of the issue would be:

   How could the NCDC collection of radar level II and level III data 
be made accessible to the IDV?

If you guys at NCDC are up for it, we would be interested in focusing 
some effort in the next month or so on helping you setup the appropriate 
servers at NCDC and test them out.

Seems like the first thing would be to get an ADDE server set up at NCDC 
to serve the level III data. I don't think the IDV needs any THREDDS 
stuff to access ADDE served level III data. (Don, is that right?) 
Though, because of the size of the NCDC data holdings (Glenn, how much 
level III data would you want to make available at first?), we might 
want to look at some cataloging capabilities.

Second would probably be more testing of the ESML-OPeNDAP level II radar 
data server. We've already started looking at this here at Unidata to 
see what it would take to access the data from the IDV. I think we've 
had some interactions with the ESML people on this as well. Again we can 
look at cataloging this data both to let the IDV know what the data is 
if necessary and to deal with a really large collection of level II 
radar data.

I guess that's about it. Does anyone see something I'm forgetting?

Glenn, does this sound like something you guys are up for?

Ethan
