Paper Abstract

Aerosol retrieval algorithm of EarthCARE/MSI is divided into two parts. One is ocean algorithm, and the other is land algorithm. To retrieval over ocean, two-channel method of band1 and band2 is used. To retrieve aerosol over land, we need to estimate ground reflectance. One idea to estimate the ground reflectance is to make MSI's original albedo product by choosing minimum reflectance data of MSI. But, the swath of MSI is as narrow as 150km. It is difficult to gather enough radiance data to make ground reflectance. Another idea is to extrapolate ground reflectance on larger wavelength to the ground reflectance on visible wavelength. We did example analysis with several methods and coefficients. Minimum reflectance method of 0.38 μm and that of 0.68 μm shows close results. On the other hand, Modified Kaufman method shows larger aerosol optical thickness pattern than others.
