Sensor networks collect vast amounts of real-time information about the environment, business processes, and systems. Archived sensor data is valuable for long-term analysis and decision making, which requires it be suitably archived, indexed, and validated. In this paper, we describe a general approach to managing and improving data quality by the generation and validation of metadata and the logging of workflow events. The approach has been implemented within a system archiving terabytes of U.S. weather radar data. The data quality system has resulted in the detection of data errors while simplifying the administration of the complex archive system.
