Monitoring Data Quality via Satellite Integrated Calibration/Validation System (ICVS)
Explore the OMPS ICVS, a system designed to monitor and evaluate the performance of OMPS and its SDR, aiding in anomaly investigation and resolution. The ICVS team collaborates to establish best practices for performance evaluation and visualization of instrument status. Discover how high-level instrument status, operation status, instrument performance, and SDR performance are assessed and compared with other instruments. Detailed insights into instrument component temperatures, correction tables, and radiance/reflectivity product comparisons are provided, offering a comprehensive overview of data quality monitoring processes.
