한반도 중부지역의 밀에 대한 오존 위해도 평가

초록

This study was performed to assess the level of ozone risk for wheat in the central region of the KoreanPeninsula by using two ozone indices, the ozone-concentration based index (AOT40) and the ozone-flux basedindex (AFstY), and to analyze the relationship between the two indices. In the present study for AFstY calculation,the Monin-Obukhov length was estimated using the Pasquill stability class which was determined from routinemeteorological data such as wind speed, solar radiation and cloudiness. The AOT40 and AFst6 indices were calculated for wheat at 3 sites in the central region of the Korean Peninsuladuring a period of 3 months from April 1 to June 30, 2006. It should be noted that the estimation of ozone indexAFst6 in this study was performed under several assumptions. The results for both indices, AOT40 and AFst6,showed that agricultural crops could be seriously damaged by ozone in the local region of the Korean Peninsula.
