Prisma Products and Applications for Aquatic Ecosystems

The monitoring of water biophysical parameters and the management of aquatic ecosystems are crucial to address the current state of degradation of inland and coastal waters. Water quality monitoring not only supports management decisions, but also provides important insights to better understand changing structural and functional processes. To date, most applications developed for inland waters have relied on multispectral and medium to coarse resolution satellites, while a new generation of spaceborne imaging spectroscopy is now available and future global missions are under development. This study aims to evaluate both the Level 1 PRISMA products, in different processing versions, and the Level 2 products based on coincident in-situ data collected in different aquatic ecosystems. Examples of water quality mapping in different use cases will then be provided, also in synergy with other missions such as EnMAP and Sentinel-2.
