Title Dynamic, Rule-based Quality Control Framework for Real-time Sensor Data
Archive All Files / Documents / Publications / Conference Papers

The volume of monitoring data that can be acquired and managed by Long Term Ecological Research sites and environmental observatories has increased exponentially over time, thanks to advances in sensor technology and computing power combined with steady decreases in data storage costs. New directions in environmental monitoring, such as sensor networks and instrumented platforms with real-time data telemetry, are raising the bar even higher. Quality control is often a major challenge with real-time data, though, due to poor scalability of traditional software tools, approaches and analysis methods. Software developed at the Georgia Coastal Ecosystems Long Term Ecological Research Site (GCE Data Toolbox for MATLAB) has proven very effective for quality control of both real-time and legacy data, as well as interactive analysis during post processing and synthesis. This paper describes the design and operation of the dynamic, rule-based quality control framework provided by this software, and presents quantitative performance data that demonstrate these tools can efficiently perform quality analysis on million-record data sets using commodity computer hardware.
