Hi,

No worries.

OK.

Of course.

The volume of data flowing in the IDD is a moving target, so any estimate made
today
will be wrong tomorrow. That being said, you could do some "back of the
envelope"
calculations by extrapolating the average volume of data available in the
datastreams
desired per hour and then multiplying by the number of hours in a year. For
instance, a randomly chosen real-server back end of our idd.unidata.ucar.edu
top level IDD relay cluster can be found in:
http://rtstats.unidata.ucar.edu/cgi-bin/rtstats/siteindex?cluster2.unidata.ucar.edu
The link at the lower left of this page will generate a snapshot list of
the volume of data flowing in each of the datastreams that this node is
handling:

This looks like:

The volume of data flowing in the IDD changes all of the time as new model
output
is added, new satellite imagery is added, higher resolution radar data becomes
available, etc. The IDD truly is a fire hose, and its stream is continually
growing.

OK, sounds good.
re:

No worries.
Do you/NPS have a road map for where you are heading wrt cloud computing? If
yes, are
you willing to share it?
Cheers,
