Assessment of AERONET-OC Lwn uncertainties
This study presents a detailed analysis of the uncertainties affecting the normalized water-leaving radiance (Lwn) from above-water measurements performed within the context of the Ocean Color component of the Aerosol Robotic Network (AERONET-OC). The analysis, conducted in agreement with the “Guide...
