This talk highlights the importance of data quality and presents a concept for harmonising data from several Earth observing satellites through a space-based system called satellite cross-calibration radiometer.
Data streams from the growing constellation of commercial Earth observation (EO) satellites are of variable quality for several reasons such as, differences in sensor design, calibration methods, or post-launch performance monitoring. Inconsistent data quality limits the potential for integrating data from multiple EO sources to support monitoring applications that cover long periods. Recent reports have highlighted quality assurance and trust in data, as critical elements that support a thriving EO sector. This talk will cover approaches to address EO data quality issues and presents the concept of an in-orbit calibration system called Satellite Cross-calibration Radiometer, for characterising several satellite-based sensors, to improve the quality and consistency of data generated by different sensor systems. The presentation also highlights how improvement in data quality across multiple EO platforms can provide better insights from the data, reduce the risks for access to science-quality data in Australia, and deliver a higher return on the global investments in EO.
