[IDD #TAQ-497422]: Radar level 3 distribution

Yup, more data all the time :-)

That is the way we distribute Level III files contained in the NOAAPort SBN.
Breaking the offerings into individual products allows the end user to
pick and choose what s/he really wants.

re:
> Each file likely will be named SDUS.. file.

Our convention for naming products is easily seen by running the LDM
'notifyme' utility.  For instance:

<as 'ldm'>
notifyme -vl- -f NEXRAD3 -h idd.cise-nsf.gov
Jul 20 22:27:35 notifyme[2484] NOTE: Starting Up: idd.cise-nsf.gov:

As you can see, the Product IDs we use contain the WMO ID (e.g., SDUS35, 
SDUS55, etc.), the
date and time (e.g., 202223 -> day 20, time 2223Z), _and_ information about 
what the
product is and what station it is for (e.g., NCRGJX -> NCR product for GJX).  
We find
that this kind of granularity is very useful for our users.

We would be very happy if you chose to implement a product naming convention
that uses what we have been using for over a decade.  This would make life
easier for users who feed directly from you and from the IDD.

Speaking of access... a long time ago we requested that we be given free
access to the full set of Level III products so that we could deliver them
to the IDD community.  Is there any update on if/when this will be possible?

Cheers,

Tom
