Hyperspectral Remote Sensing of Optically Shallow Waters: Radiometric Challenges and Strategies
Abstract
Hyperspectral ocean color remote sensing allows for in-depth investigation of the water quality and biodiversity of shallow water ecosystems including coral reefs. Although decades of efforts have led to great achievements in shallow water remote sensing, challenges still exist. In this study, we review the progresses in the precise measurement of shallow-water environments and retrieval of sub-surface properties from water/ocean color, and highlight the major challenges facing the inversion of water and bottom properties from in situ and airborne radiometric measurements. We discuss potential solutions towards more accurate retrieval of water-leaving radiance from remote and in situ platforms as well as improved retrieval of sub-surface properties. This study is funded by the NASA HyspIRI and CORAL projects.
