UCP (Unit Control Position): The WSR-88D radar operator uses this to control the entire radar
system. One of the main things that the radar operator will do at the UCP is change volume scan
strategies of the antenna. These volume scan strategies tell the radar how many elevation angles
will be used during a single volume scan (a volume scan is the completion of a sequence of
elevation angles), and the amount of time it will take to complete that sequence of elevation cuts,
each one being a single rotation of the antenna's 1 degree beam at selected elevation angles. The
WSR-88D uses 3 scan strategies. They are the following: 14 elevation angles in 5 minutes (this is
used during severe weather situations), 9 elevation angles in 6 minutes (this is used when there is
precipitation within 248 nautical miles of the radar), and 5 elevation angles in 10 minutes (this is
used when there is no precipitation within 248 nautical miles). The radar operator at the UCP can
also adjust the radar products and help the users out with their communication problems.
