Abstract

Abstract

The problem of secondarily-deriving the columnar aerosol grain density from a satellite-retrieved aerosol optical thickness is discussed.It is feasible to retrieve the columnar aerosol grain density with the multi-wavelength aerosol optical thickness.The reliability of the multi-wavelength aerosol optical thickness directly affects the retrieved columnar aerosol grain density.The aerosol grain-size extinction weighting coefficient is proposed and the variety of the grain-size extinction weighting coefficient with the particle radius indicates that the retrieval of the aerosol columnar grain distribution in an accumulation mode and a coarse mode is believable.Lastly,using the Monte-Carlo simulation method,the columnar aerosol grain density in the accumulation mode and the coarse mode was extracted from the Sea WiFS-retrieved aerosol optical thickness over the China seas in 2002.The results show that the columnar aerosol grain density in the accumulation mode is higher two or three levels than that in the coarse mode,and their dist ribution has the similar trend over the China seas.The columnar aerosol grain density over the coast is always higher than over the ocean.It is the highest in spring,especialy over the Huanghai Sea and the East China Sea.
