Hi Adam,

re:

Very good.

> I read FNMOC feed is having problems...any new on that?

No news yet.  We are waiting until the new person at FNMOC gets things running
smoothly again.

LSU is not one of the sites that relays the NEXRAD2 data (Nexrad full volume
scan data).  The toplevel relay sites for NEXRAD2 data in the Unidata community
are:

Purdue
Unidata
NSF/ATM

Are you wanting to get NEXRAD2 data?  Just so you know, the volume in that 
datastream
is very large.  Here is a snapshot of volumes for the most popular datastreams 
in
the IDD:

Data Volume Summary for idd.unidata.ucar.edu

Maximum hourly volume   8440.228 M bytes/hour
Average hourly volume   4637.851 M bytes/hour

Average products per hour     180948 prods/hour

LIGHTNING                 0.039    [  0.001%]        0.158        9.633

As you can see from this listing, the NEXRAD2 data is 1.5 GB/hour on average.

Sirocco gets the majority of its data from a NOAAPort ingester at LSU.  The
feeds available from NOAAPort are:

IDS|DDPLUS
HDS     <- medium resolution model data mostly in GRIB1
NGRID   <- high resolution model data in GRIB2
NIMAGE  <- GOES-East/West image sectors
NNEXRAD <- Nexrad Level III products

OK.

> As I said, just trying to get everything in its correct place.

I understand.

> Thanks,

No worries.
