Abstract

We present linear particle depolarization ratio at 440, 675, 870, and 1020 nm retrieved from measurements with an AERONET sun/sky radiometer at the source region of Asian dust, Dunhuang. The linear particle depolarization ratios are retrieved at the two receptor sites (Gosan and Osaka). The highest linear particle depolarization ratio of 0.34 at 1020 nm is retrieved from nearly pure Asian dust. The linear particle depolarization ratio decreased as the volume concentration of fine-mode particle increased. We can confirm that the ratio of Asian dust is changed by the value of the linear particle depolarization ratio retrieved by AERONET data.

황사의 주요 발원지인 중국 북부 둔황지역에 선포토미터를 설치하여 440, 675, 870 그리고 1020 nm 채널에서 황사의 파장별 입자편광소멸도를 산출하였다. 이와 함께 발원한 황사가 장거리 수송과정에 위치한 제주 고산과 일본 오사카에 설치된 선포토미터를 함께 분석하였다. 황사 발원지에서 1020 nm 파장에서 입자편광소멸도가 0.34로 가장 높은 수치를 보였다. 또한, 초미세먼지농도가 증가하는 경우 입자편광소멸도는 감소하는 경향을 보였다. 우리는 본 연구에서 선포토미터의 입자편광소멸도 산출을 통해 에어로졸에서 황사의 구성 비율이 변화함을 확인하였다.
