Re: [ldm-users] NEXRAD2/NEXRAD3 lag?

Karen just stated it all pretty well. My affiliation isn't what this is
about. I spent a long time, before I came to OU, and started working with
the lab, working with LDM systems. The data I'm getting for our research
effort (non-operational) comes from Unidata and Texas A&M, and the Unidata
stats are what I look at, especially if we see what we perceive as delays.
Our scripts will slow down if things are delayed too much, so I'd see that,
but I do not, any longer spend a lot of time checking latencies.

I'm also confused with what Blair's reporting. I'd like to have time to
look into it and may find some later this week, but doing that aspect of
troubleshooting unrelated to our program isn't in my work-plan anymore.
It'll have to happen some evening, if it does at all, and my evenings are
pretty full still.

And finally, a couple of things: Robert, I don't think you were dissing the
Lab, and if I gave the impression the Lab had anything to do with max
latencies, I was very wrong. My comments, as they've been for years, are my
own, and what I have been seeing is data coming from .edu sources,
primarily Texas A&M (who get their primary data from IRADS) and Unidata. My
feed actually goes to an ou.edu machine for the research we're doing, so in
a lot of ways, it's .edu all the way. I'm just surprised Blair's seeing the
problem.

Now I'll back away before I get in any more trouble!
