Thirteen years of observations on primary sugars and sugar alcohols over remote Chichijima Island in the western North Pacific

Abstract. In order to understand the atmospheric transport of bioaerosols, we conducted long-term observations of primary sugars and sugar alcohols over remote Chichijima Island in the western North Pacific from 2001 to 2013. Our results showed that concentrations of total sugar compounds for 13 years ranged from 1.2 to 310 ng m−3 (average of 46 ± 49 ng m−3). We found that atmospheric circulations significantly affect the seasonal variations of …
