WSR-88D Radar Products Generator (RPG) at NWS Louisville The Radar Products Generator (RPG) is a integral component of the WSR-88D Doppler Radar. Inside these "racks" are various communications, software, and storage devices. Data is received at NWS Louisville from the Radar Data Acquisition (RDA/antenna) at Ft. Knox. The data is processed to create many data fields images that can be viewed on AWIPS workstations and the PUP workstation. Some of the data available is described in the document "Overview of the WSR-88D Radar System." A number of software algorithms create other products as well and check for various data threshold values. Once these values are met (usually in significant weather events), alerts are sent to forecasters at the workstations.  Basically, the RPG is the clearinghouse for WSR-88D radar information. Data also can be archived which is useful in post-storm analysis studies and other research purposes. A PC is connected to the RPG to monitor system status and input commands as needed.
