Hi Russ,

Correct.

re:
> You and Kathy are OK but the rest of Boulder is a mess.

Yes, Cathy (that is Cathy with a 'C', not a 'K') are doing well, thanks!

re:
> RE: N0Q - Should I continue my switch over to N0Q or revert to N0R until N0Q

Revert to use of N0R composites.  We will send a notification to the
ldm-users email list when the N0Q product is officially added to the
FNEXRAD datastream.

Just so that you (and anyone who reads these exchanges; they are made
public after all) know: nothing we do is operational.  That is why
I always surround "operational" in quotes!

The are not.

re:

I think that this is the case, but it could be that the pixels from the
most recently added product "win".

re:
> When are sites removed from the composite?

When the NTP product from a site stops being reported.

re:
> Do
> the sites "clear" the display after the precip event (yielding a blank image)?

Sometime after the precipitation even ends, the PUP stops sending
new NTP products.  I do not know the criteria used at the PUP, and
I don't ever remember seeing a description of the NTP product that
goes into that kind of detail.

Cheers,

Tom
