The WSR-88D Radar Operations Center (ROC) is responsible for implementing new signal processing algorithms planned for deployment in the Open Radar Data Acquisition (ORDA) System. The capture and playback of time series data allows for selection of relevant weather data and repetitive testing of an algorithm under development. It provides the ability to play recorded data through the processor, then to compare results with the output of “Legacy” processing. This paper will provide the status of the current record and playback capabilities, a historical perspective, and a discussion of the application and benefits to the research community
