Determinations of Two-Layered Atmospheric Extinction Coefficients from Sun-Photometer Measurements

摘要

An algorithm is present in this paper for determination of the two-layer atmospheric mearl extinction coefficients from sun-photometers measurements．The atmospheric layer is assumed as uniform parallel spherical surfaces in this study,which is more reasonable for the true atmospheric layer．The algorithm is applied to the data measured by means ofthe CIMEL CE-318 instrument and the reasonable results are Obtained．
