Measuring Marine Suspended Sediment Concentrations from Space: History and Potential

摘要

Advances in analysis of particle scattering and absorption have improved understanding of howsuspended particles influence the light field and the resulting ocean color signature. These advancesenable algorithms which uncouple the spectrum into spectral backscattering, detritus absorption,colored dissolved organic matter, and chlorophyll. Future algorithms will determine linkages betweenoptical components beyond merely the suspended particulate matter (SPM) product, including theinfluence of particle size, shape, refraction, stratification, and composition. This paper examineshistorical progress in research on space-based SPM observations; evaluate the status of currentalgorithms and models; describe user community interest in SPM data products; and discuss strategiesto promote publically-available SPM data products.
