Advances in the Ocean Color Component of the Aerosol Robotic Network (AERONET-OC)

Abstract The Ocean Color Component of the Aerosol Robotic Network (AERONET-OC) supports activities related to ocean color such as validation satellite data products, assessment atmospheric correction schemes, and evaluation bio-optical models through globally distributed standardized measurements water-leaving radiance aerosol optical depth. In view duly assisting AERONET-OC user community, this work (i) summarizes latest investigations on a number scientific issues above-water radiometry, (ii) emphasizes network expansion that from 2002 until end 2020 integrated 31 effective measurement sites, (iii) shows equivalence product accuracy across sites time for performed with different instrument series, (iv) illustrates variety water types represented by ensuring diversity observation conditions, (v) documents availability corrected bidirectional effects applying method specifically developed chlorophyll- -dominated waters an alternative one is likely suitable any type.
