As dust storms originated in Neimongu Plateau and Manchuria became more
frequent in Korea, there was a growing need for Asian Dust (Hwangsa) monitoring stations in
North Korea, which is a pathway of Asian Dust to South Korea. The South Korean and the North
Korean Governments agreed to build the Automatic Weather System and the PM10 measurement
instruments in the Gaeseong Industrial Zone and the Keumgangsan Tourist Region, North Korea
in 2007. PM10 mass concentration data in the Keumgangsan Tourist Region could be collected
only during the period from September 2007 to May 2008. In this study, daily, monthly and
diurnal variations of PM10 mass concentration of the Keumgangsan are analyzed and compared
with those of Sokcho and Gwangdeoksan. Three sites show similar variations in daily and
monthly means. Correlation coefficients (r) between Sokcho and Keumgangsan, and between
Gwangdeoksan and Keumgangsan are 0.89 and 0.67, respectively. But diurnal variation at
Keumgangsan has a distinct feature compared to the other sites. Diurnal PM10 variation shows
two peaks around 8 AM and 4-5 PM and very low at night. The difference between the daily
maximum and minimum is 20~60 μg m-3 during September to November 2007. Temperature,
relative humidity and wind speed from the Keumgangsan AWS data were compared with those
