The accuracy of primary satellite ocean color data products from the Moderate Resolution Imaging Spectroradiometer (MODIS-A) and the Visible/Infrared Imager/Radiometer Suite (VIIRS), is investigated in the Western Black Sea using in situ measurements from the Gloria site included in the Ocean Color component of the Aerosol Robotic Network (AERONET-OC). The analysis is also extended to an additional well-established AERONET-OC site in the northern Adriatic Sea characterized by optically complex coastal waters exhibiting similarities with those observed at the Gloria site. Results from the comparison of normalized-water leaving radiance Lwn indicate biases of a few percent between satellite derived and in situ data at the center-wavelengths relevant for the determination of chlorophyll-a concentration (443-547 nm, or equivalent). The differences are significantly more pronounced at the blue (i.e., at 412 nm) and red (i.e., 667 nm, or equivalent) center-wavelengths.
