Sentinel-3 coastal analysis ready data: s3card

The S3CARD framework was designed to facilitate the use of Sentinel-3 OLCI imagery for coastal water quality applications. We integrate atmospheric, glint, and adjacency corrections into a global, gridded framework, providing consistent datasets that can support time series analysis. 

We validated the framework using global AERONET-OC observations and applied it in the Mississippi Sound, where it successfully captured patterns of turbidity and water clarity over time. 

Our goal is to support more consistent and accessible satellite-based assessments in coastal environments.
