Long-term Observations of Transboundary Air Pollutants Such as Total Odd Nitrogen Species at Suzu, Noto Peninsula

Abstract

In East Asia, emissions of air pollutants have been decreasing, but the decreasing rates depend on the composition of the pollutants, and in recent years the relative importance of transboundary pollution originating from nitrogen oxides has been increasing. We have been conducting continuous observations of total odd nitrogen species, total inorganic nitrate (the sum of gaseous nitric acid and particulate nitrate), ozone, carbon monoxide, and so on at Suzu, Noto Peninsula for about 15 years. In this presentation, we report the results of the long-term continuous observations of these transboundary air pollutants at Suzu.
