AERONET-OC: An Overview

The Ocean Color component of the Aerosol Robotic Network (AERONET-OC) was established to support satellite ocean color validation activities in coastal waters through standardized measurements of atmospheric and marine optical quantities. Specifically, AERONET-OC can provide in situ values of the normalized water-leaving radiance and aerosol optical thickness through autonomous radiometers operated on fixed platforms in coastal waters. This work presents the rationale for the network together with an overview of the measurement sites and applications. Focus is brought into the assessment of accuracies of coastal normalized water-leaving radiances from current satellite ocean color sensors: the Medium Resolution Imaging Spectrometer (MERIS) onboard the ENVISAT platform, the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard the AQUA platform and the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) onboard the OrbView-2 satellite.
