Recently, Jeollabuk-do has been reported as a province where the PM<SUB>10</SUB> concentration is one of the highest levels in South Korea. To explore the characteristics and origins of the PM<SUB>10</SUB> in Jeollabuk-do, we present one of the first long-term datasets including a statistical analysis of PM<SUB>10 </SUB>concentrations obtained from six cities in the province from 2010 to 2015. During the entire periods, the mean hourly PM<SUB>10</SUB> concentration was 49.3 μg/㎥, which correspond to the annual ambient air quality standards for PM<SUB>10</SUB> in South Korea, and the annual PM<SUB>10</SUB> concentration of each city showed a similarity in year-to-year variations. In the monthly variation of PM<SUB>10</SUB>, the PM<SUB>10</SUB> concentrations showed a maximum value in May that was one of the top levels among the provinces of Korea while the concentrations were dramatically decreased in August showing one of the lowest levels among the provinces in Korea. For the diurnal variation of PM<SUB>10</SUB>, the PM<SUB>10</SUB> concentration was enhanced during the rush hours together with gaseous species of NO₂, and CO. When the high concentrations of PM<SUB>10</SUB> were observed (the highest 10% of the PM<SUB>10</SUB> mass contribution), temperature and relative humidity were low. Using HYSPLIT backward trajectories and cluster analysis for the high PM<SUB>10</SUB> concentrations, we found that the pollution plumes were transported mainly from China.
