Impact/Purpose:
Eutrophication of waterbodies represents an ongoing environmental and public health concern. Monitoring by satellite remote sensing has proven effective, but most sensors currently in use have a relatively coarse spatial resolution (~300 m); this limits monitoring efforts along shorelines—where most human recreational exposure occurs—and in small waterbodies. The Sentinel-2 satellite constellation delivers finer resolution (20 m), offering strong potential for managers and stakeholders concerned with the coarse nature of most operational satellite water quality products.
Description:
Chlorophyll a is often used to assess eutrophication and general ecological condition. The presentation will demonstrate calculation of a chlorophyll a algorithm called the Maximum Chlorophyll Index (MCI) using Sentinel-2 data. Additionally, performance of the MCI will be quantified using a suite of error metrics, and by assessing accuracy of trophic state identification.
