nbsp; nbsp;This study was conducted as the Long-range Transboundary Air Pollutants (LTP) Project among Korea, Japan and China. The research aims to understand atmospheric environment in Northeast Asia as well as determine causes of air pollution in the region. It ultimately wants to provide scientific data for establishing air pollution reduction measures. To this end, several activities were performed including aircraft measurement, upper and synoptic atmosphere analysis, and modeling analysis. nbsp; nbsp;Aircraft measurement was carried out in 2010 during two intensive measurement periods in vertical and zonal paths. The first measurement period was between May 15~25 for 7 times, and the second one was November 15~22 for 8 times. nbsp; nbsp;The highest pollutants concentration was observed in 20 May 2010. On this day, the mean concentration of SO₂ was 5.56 ppb, CO was 0.23 ppm, O3 was 9.47ppb, NOx was 4.01 ppb, PAN was 1.37 ppb, and particle number was 194.968 N/㎤, higher than the other measurement days. nbsp; nbsp;The modeling result during the aircraft measurement was quite reliable as it was performed based on the 2006 INTEX-B emission data. In addition, high concentration events and tracts of air pollutant movement were well simulated in the model. But the modeling result also requires some further improvement as it tends to underestimate their absolute values. |
