In order to clarify the impact of regional air pollution in Siberia and trans-boundary air pollution to Japan caused by forest fire in Siberia, we observed the air pollutants utilizing high time resolution (daily) sampler. We conducted cooperative research with Linmological Institute, Russian Academy of Science, Siberian Branch. We made on site visit in every year to discuss how to proceed the detail of cooperative research.The peak concentration of ionic species in aerosol was observed in 2nd August in 2005. Sulfate level exceeded 4μg/m^3. The high concentration of potassium ion is indicative of forest fire, however, the high concentration is restricted only one day, so small forest fire is expected. The possibility of trans-boundary air pollution to Japan is excluded for the larger than 10μg/m^3 of sulfate was not observed.We analysed EANET continuous monitoring data of sulfur dioxide in Rishiri island, Tappi as well as Sado-seki. These sampling sites are all located onshore line of … More Sea of Japan, so they are susceptible to trans-boundary air pollution from Siberia. From April, to June, the concentration is extremely low except for April (6ppbv) in Sado-seki. From July to September, the concentrations of sulfur dioxide are low in 3 sampling sites. From December the high concentrations are observed in 3 sampling sites concurrently. From January to March, larger than 5ppbv of sulfur dioxide were observed three times. The backward trajectory analysis with NOAA in U.S., indicated the transport of air mass over Russia in 22nd and 23rd December, however, it was not clear that it was caused by forest fire or not. Unfortunately, we could not clarify the apparent effect of forest fire in the atmosphere from observation, however, we could make capacity building to monitor the air pollutants caused with forest fire in Siberia area. It is great contribution that we can establish air pollutants monitoring system in Siberia, where is considered the risk of forest fire by accelerated global warming. Less

为了明确西伯利亚区域空气污染和西伯利亚森林火灾引起的跨界空气污染对日本的影响，我们利用高时间分辨率（日）采样器对大气污染物进行了观测。与俄罗斯科学院西伯利亚分院湖泊研究所进行了合作研究。我们每年都进行实地考察，讨论如何进行合作研究的细节。2005年8月2日观测到气溶胶中离子浓度的峰值。硫酸盐含量超过4μg/m^3。高浓度的钾离子预示着森林火灾的发生，但高浓度仅限一天，因此预计会发生小规模的森林火灾。由于没有观察到大于10μg/m^3的硫酸盐，因此排除了日本跨境空气污染的可能性。我们分析了Rishiri岛、Tappi岛和Sado-seki岛的EANET二氧化硫连续监测数据。这些采样点都位于日本海的海岸线上，所以它们很容易受到西伯利亚跨境空气污染的影响。4月至6月，除4月在佐道关（6ppbv）外，浓度极低。7 - 9月，3个采样点二氧化硫浓度较低。从12月开始，3个采样点同时出现高浓度。1 ~ 3月，共3次二氧化硫浓度大于5ppbv。与美国NOAA的反向轨迹分析显示，12月22日和23日俄罗斯上空有气团输送，但不清楚是否是森林火灾造成的。遗憾的是，我们无法从观测中明确森林火灾对大气的明显影响，但我们可以对西伯利亚地区森林火灾造成的大气污染物进行监测能力建设。在因全球变暖而面临森林火灾风险的西伯利亚地区建立空气污染物监测系统是我们的巨大贡献。少
