Many cohort studies have reported associations of individual-level long-term exposures to PM<SUB>10</SUB> and health outcomes. Individual exposures were often estimated by using exposure prediction models relying on PM<SUB>10</SUB> data measured at national regulatory monitoring sites. This study explored spatial and temporal characteristics of regulatory PM<SUB>10</SUB> measurement data in South Korea and suggested PM<SUB>10</SUB> concentration metrics as long-term exposures for assessing health effects in cohort studies. We obtained hourly PM<SUB>10</SUB> data from the National Institute of Environmental Research for 2001~2012 in South Korea. We investigated spatial distribution of monitoring sites using the density and proximity in each of the 16 metropolitan cities and provinces. The temporal characteristics of PM<SUB>10</SUB> measurement data were examined by annual/seasonal/diurnal patterns across urban background monitoring sites after excluding Asian dust days. For spatial characteristics of PM<SUB>10</SUB> measurement data, we computed coefficient of variation (CV) and coefficient of divergence (COD). Based on temporal and spatial investigation, we suggested preferred long-term metrics for cohort studies. In 2010, 294 urban background monitoring sites were located in South Korea with a site over an area of 415.0 km2 and distant from another site by 31.0 km on average. Annual average PM<SUB>10</SUB> concentrations decreased by 19.8% from 2001 to 2012, and seasonal PM<SUB>10 </SUB>patterns were consistent over study years with higher concentrations in spring and winter. Spatial variability was relatively small with 6~19% of CV and 21~46% of COD across 16 metropolitan cities and provinces in 2010. To maximize spatial coverage and reflect temporal and spatial distributions, our suggestion for PM<SUB>10</SUB> metrics representing long-term exposures was the average for one or multiple years after 2009. This study provides the knowledge of all available PM<SUB>10</SUB> data measured at national regulatory monitoring sites in South Korea and the insight of the plausible longterm exposure metric for cohort studies.
