Abstract

<tt>In several epidemiological studies, the arrival of an Asian Dust event has recently been evaluated using the Dust extinction coefficient derived from the NIES Mie Lidar network. We analyzed the relation between the NIES Dust extinction coefficient and surface aerosol measurement in the northern part of Kyushu, Japan. Although a good correlation was observed between the Dust extinction coefficients at a lower height and [SPM] - [PM</tt><tt>_2.5</tt><tt>] in Nagasaki, a better correlation was found between the Dust extinction coefficients at Nagasaki and Fe concentration in PM</tt><tt>_2.5 </tt><tt>collected at Fukuoka in spite of their geographical separation of 100 km. The arrival of Asian Dust can be clearly identified when the Dust extinction coefficient> 0.1 km</tt><tt>^-1 </tt><tt>using the Fe concentration as an indicator. In the prominent Asian Dust events, the ratio [SPM] / [PM</tt><tt>_2.5</tt><tt>] ratio characteristically showed the value of 3, which presumably reflects the typical characteristics of the Asian Dust size distribution that has experienced the long-range transports</tt><tt>. </tt>
