Kevin,

So, you are a celebrity (Sunday Parade article on salary comparisons)!

Sounds positive.

The machine that was feeding the NOAAPORT satellite imagery crashed and
burned after a power failure (it wasn't plugged into the UPS as it
should have been).  It took until after noon to get it back up.

No, it wasn't.  I had to approve the subscription since the domain of
the machine you submitted the request from did not match the domain of
the email address you were subscribing.  In cases like this, support
must decide whether or not the signup is legit or not.  No biggie, this
happens all of the time.

No.

Surface obs were missing near the end of the day because of a situation
related to the machine crash mentioned above.  This late day outage was
my fault: I fat fingered an ldmd.conf request line and stopped
ingestion of observational data (sigh).

>One other question about the satellite imagery - if

You could setup multiple pqact.conf entries, one for each type of image
you want to ingest, instead of one action for all of the images.  This
way you can really tailor what you want to file.  If you decide you
will never want the images you do not file, then you need to alter your
request line for NIMAGE in ldmd.conf to not request those images.  This
will spare you some network bandwidth.

I just checked the McIDAS-XCD decoded RUC 18 Z run for today, and do
see CAPE and Helicity grids:

So, yes, the RUC does have CAPE and Helicity grids in it as a matter of
course.

This is, of course, the goal: hands off ingestion/decoding and hands on
display/analysis.
