The spatiotemporal variations of surface air pollutants (O3, NO2,SO2, CO, and PM10) with four land-use types, residence (R),commerce (C), industry (I) and greenbelt (G), have been investigated at 283stations in South Korea during 2002–2013, using routinely observed data. Thevolatile organic compound (VOC) data at nine photochemical pollutantmonitoring stations available since 2007 were utilized in order to examinetheir effect on the ozone chemistry. The land-use types, set by the Koreangovernment, were generally consistent with the satellite-derived land coversand with the previous result showing anti-correlation between O3 andNO2 in diverse urban areas. The relationship between the two pollutantsin the Seoul Metropolitan Area (SMA) residence land-use areas wassubstantially different from that outside of the SMA, probably due to thelocal differences in vehicle emissions. The highest concentrations of airpollutants in the diurnal, weekly, and annual cycles were found in industryfor SO2 and PMPM10, in commerce for NO2 and CO, and in greenbeltfor O3. The concentrations of air pollutants, except for O3, weregenerally higher in big cities during weekdays, while O3 showed its peakin suburban areas or small cities during weekends. The weekly cycle andtrends of O3 were significantly out of phase with those of NO2,particularly in the residential and commercial areas, suggesting that vehicleemission was a major source in those areas. The ratios of VOCs to NO2for each of the land-use types were in the order of I (10.2) > C(8.7) > G (3.9) > R (3.6), suggesting that most areas in South Koreawere likely to be VOC-limited for ozone chemistry. The pollutants (NO2,SO2, CO, and PMPM10 except for O3 have decreased, most likelydue to the effective government control. The total oxidant values (OX =O3 + NO2) with the land-use types were analyzed for the local andregional (or background) contributions of O3, respectively, and theorder of OX (ppb) was C (57.4) > R (53.6) > I (50.7) > G (45.4),indicating the greenbelt observation was close to the background
