Outline of Research at the Start

冬季~春季の日本周辺では、しばしばエアロゾル等の大気汚染物質が増加し、越境汚染の問題など社会的影響も大きい。しかし、東アジアのエアロゾル放出量には推定精度の低い場所の情報も含まれるため、日本付近へのエアロゾル到達量予測やエアロゾルの気候影響評 価の精度を下げてしまう問題がある。本研究では、放出量の推定精度の低い場所の汚染物質を検出しやすい秋田県で地上観測とドローンによる大気鉛直観測を行い、IPCC報告書等に用いられてきた化学輸送モデルに観測情報を同化する画期的な手法で、東アジアの放出量を大幅に改善したエアロゾル予測モデルを開発することを目的とする。

Outline of Final Research Achievements

In this study, atmospheric observations were carried out at the Ogata Campus of Akita Prefectural University in northern Japan and combined with chemical transport model simulations to analyse the dynamics of aerosols reaching Japan. Atmospheric aerosol observations were conducted with a pocket-sized black carbon (BC) aerosol monitor and the collection with an air sampler on the ground station. The UAV was also equipped with a carbon dioxide concentration measurement and a simple BC measurement for atmospheric vertical observations. Observations from a simple BC measurement during the observation campaigns detected several high BC events near Akita Prefecture, and further analysis of BC concentrations and meteorological fields in atmospheric chemical transport models for the same period showed that the high concentration events were associated with long-term transport from the Asian continent.

Academic Significance and Societal Importance of the Research Achievements

冬季~春季の日本周辺では、しばしばエアロゾル等の大気汚染物質が増加し、越境汚染の問題など社会的影響も大きい。しかし、東アジアのエアロゾル放出量には推定精度の低い場所の情報も含まれるため、日本付近へのエアロゾル到達量予測やエアロゾルの気候影響評価の精度を下げてしまう問題がある。本研究では、こうした課題を克服するため、放出量の推定精度の低い場所の汚染物質を検出しやすい秋田県で地上観測とドローンによる大気鉛直観測を行い、化学輸送モデルに観測情報を同化して放出量の推定精度向上を図ることを目的としている。
