may look like nothing more than a room full of mainframe computers,
and you'd be right! Hidden in a room located behind the operations
floor
are the "brains" behind the computers. There are two such rows. The mainframe
computers powering AWIPS can be seen here. The other row contains the computing
power for the WSR-88D radar.
You
may wonder how we receive data or transmit the items we produce. The
secret lies in the satellite dish seen below, on the right. This
dish lives
in our "backyard" and is our data connection to the world. All data entering
or leaving the Weather Service travels by satellite through the Control Facility
in Silver Spring, MD. The path the item takes varies slightly for outgoing
and incoming items. For products we issue, after we compose and send it, it travels
to the local River Forecast Center (RFC; for us, State College, PA or its backup
site in Taunton, MA), through the Network Control Facility (NCF), and then through
Telecommunications Gateway
in Suitland, MD. Most incoming data comes straight from the NCF to all
local Forecast Offices. Radar data and some local observations
are exceptions; they
too get funneled through the servicing RFC. In all cases, the data is bounced
off satellites high above Earth each
step of the way. Yet, data makes it between us and its destination
in a couple of minutes. Our close proximity to the national transmittal
source doesn't significantly reduce transmission time-- it might take a few seconds
less for us. It truly is quite remarkable to think of how far and
how fast the data travels.
