Liu, L., M.I. Mishchenko, I. Geogdzhayev, A. Smirnov, S.M. Sakerin, D.M. Kabanov, and O.A. Ershov, 2004: Global validation of two-channel AVHRR aerosol optical thickness retrievals over the oceans. J. Quant. Spectrosc. Radiat. Transfer, 88, 97-109, doi:10.1016/j.jqsrt.2004.03.031.

The paper presents validation results for the aerosol optical thickness derived by applying a two-channel retrieval algorithm to Advanced Very High Resolution Radiometer (AVHRR) radiance data. The satellite retrievals are compared with ship-borne sun-photometer results. The comparison of spatial and temporal statistics of the AVHRR results and the ship measurements shows a strong correlation. The satellite retrieval results obtained with the original algorithm for a wavelength of 0.55 µm are systematically higher than the sun-photometer measurements in the cases of low aerosol loads. The ensemble averaged satellite-retrieved optical thickness overestimates the ensemble averaged sun-photometer data by about 11% with a random error of about 0.04. Increasing the diffuse component of the ocean surface reflectance from 0.002 to 0.004 in the AVHRR algorithm produces a better match, with the ensemble-averaged AVHRR-retrieved optical thickness differing by only about 3.6% from the sun-photometer truth and having a small offset of 0.03.
