Remote Sensing, Volume 13, Issue 15

2021 August-1 - 205 articles

Cover Story: The integration of multiple sources of water quality data via data assimilation can result in a more holistic characterization of inland and coastal waters and consequently improve water resource management, yet methods for scaling water quality data across regions and beyond have emerged only recently. In this paper, data sources and existing data integration frameworks are reviewed to give an overview of the present status and identify the gaps in existing frameworks. We propose an integration framework to provide information to user communities through the Group on Earth Observations (GEO) AquaWatch Initiative. This aims to develop and build the global capacity and utility of water quality data, products, and information to support equitable and inclusive access for water resource management, policy, and decision making.
