Hi Bobby,

OK.

My previous comment still holds:  Penn State is one of the top level
relay nodes for data flowing in the IDD.  By this I mean that they
_have_ all of the model data, all of the satellite data, and all
of the radar data.  Art's concern was that your broadband Internet
connection would likely not be able to handle all of this data, and
I would agree in principle.

The full suite of data flowing in the IDD is best illustrated by the
following real time IDD statistics listing for the data that is available
via the Penn State relay:

As you can see from this listing, there is an average of ~6 GB/hour of
data available, and volumes can be as high as ~11.8 GB/hour.  For reference,
6 GB/hour is 13 Mb/second and 11.8 GB/hour is 26 Mb/second.

Given your desire for "all" data, you might consider the option of
installing a NOAAPort reception system at your house.  This would require
a large Cband satellite dish (3.8m or larger) a high quality PLL LNB,
a DVB-S converter (NOAAPort uses DVB-S broadcast), high quality coax
cable from the LNB to the DVB-S converter (e.g., quad shielded RG-6),
a PC running Linux or Solaris Unix that has two Ethernet interfaces,
and the software to ingest the NOAAPort datastream.  Satellite dishes
can sometimes be found for free (people getting rid of old installations),
but it is likely that you would have to purchase the PLL LNB.  You
would definitely have to purchase the DVB-S converter (we use the same
as the NWS, Novra S75), cabling and computer. The software for doing
the ingest can be gotten for free (we make our NOAAPort ingest software
available for free, but with the Big Boy warranty (i.e., do not expect
support from us)).

While installing and running a NOAAPort ingest site is not cheap, it
is likely to allow you to get more data than you could through a
commodity Internet connection.

The IDD datastreams that are populated by the NOAAPort broadcast are:

IDS|DDPLUS - global observational data
HDS        - lower resolution NCEP model output
NGRID      - higher resolution NCEP model output
NEXRAD3    - Nexrad Level III radar products
NIMAGE     - GOES satellite images

Cheers,

Tom
