Abstract

Accurate atmospheric correction is an important and essential process in ocean color remote sensing because the influence of atmosphere account for the main part of signals received by sensors. Traditional methods usually depend on in-situ measured parameters of atmosphere and could not be applied in operational system. In this paper, MODIS products synchronize with Beijing-1 micro-satellite image were used to extract the parameters of atmosphere. we chose a marine space of clean water far away from the coast in MODIS image and used the products include MOD02, MOD03 and MOD07 to calculate the aerosol radiance of near-infrared bands of MODIS which were used to extrapolate the aerosol radiances of each band of Beijing-1 micro-satellite. Brought the results into radioactive transfer equation and fulfilled atmosphere correction. We found this method can enhanced the detail information of water body, especially to case 2 water. We compared the correction results with original image and the results from 6S model; its effect was consistent well with real conditions and better than 6S model. All these indicated that this method is feasible to atmospheric correction of turbid coastal waters and expands the application of multi-spectral sensors in ocean color remote sensing.
