[IDD #VCD-819322]: FW: Clarification on how LDM, UCAR and Unidata can be used

OK, thanks for the background information.

re:

Correct.  Virtually all of the software that we make available and support
are free and open.

The real question is what site participating in the Internet Data Distribution
(IDD) system would be willing to feed you the data that you are interested
in.  We, Unidata Program Center/UCAR, can do not feed commercial entities
unless there is a measurable benefit to the Unidata community at-large.
There are university sites that participate in the IDD that are willing
to feed data to commercial entities on a quid-pro-quo or other basis.

As far as what data is flowing in the IDD, it is all of the data that
is in the NOAAPort Satellite Broadcast Network (SBN); high resolution
model output from NCEP; NEXRAD Level II data; model output from Fleet
Numerical; model output from the Canadian Meteorological Center; 
GOES satellite image sectors produced at the Space Science and
Engineering Center (SSEC) at the University of Wisconsin at Madison
(UW); and National Lightning Detection Network (NLDN) and U.S. Precision
Lightning Network (USPLN) lightning data.

If one follows the installation instructions, downloading, building and
installing the LDM should take no more than a half hour (about 10 minutes
after one gets familiar with the build/install process).  Configuring
the LDM, on the other hand, typically takes a lot longer since a site
has to figure out exactly what it wants AND doesn't want, and what
they want to do with the data received.

re:

Again, the build/install is quick and painless.  Setting up REQUESTs requires
that the site has permission from one or more upstream sites to do the
REQUESTs, and then there is determining what one wants to do with the
data as it is received.  The problem with the latter step is that it
depends on one's imagination for what is desired.

Cheers,

Tom
