[ABSTRACT] We first describe the atmospheric correction algorithm for OCTS (Ocean Color and Temperature Scanner) that has been used for the standard product generation at NASDA/EOC (Earth Observation Center). During the pixel-wise processing, the algorithm selects 2 aerosol models out of 10 candidate models and determines the "interpolation ratio" based on the estimated spectral ratio of aerosol optical thickness at 670 and 865 nm bands. We then discusses several variants of the aerosol model selection scheme and compares the performance of the schemes by simulating the atmospheric correction process in use of modeled aerosol signals. The results suggest the superiority of a scheme that iteratively determines the final candidate aerosol models. We finally compares the OCTS algorithm and the old CZCS algorithm in use of a data set of 32 in-situ observation that were conducted contemporaneously with the satellite observation. While the OCTS algorithm gives smaller estimation error in the normalized water-leaving radiances, the CZCS algorithm attaines similar performance of errer factor 2 in terms of the satellite-derived chlorophyll-a concentration. This is considered due to the nature of the estimation algorithm that relies on the ratio of the water-leaving radiances.
