Outline of Research at the Start

地球温暖化におけるエアロゾルの影響評価の高精度化と、コロナ禍によるエアロゾルの低下量を評価することを目的に、本研究では、東アジアに展開した独自の地上観測網SKYNETとAD-Net、A-Trainの衛星搭載ライダーとイメージャを解析することで、東アジアの約20年間のエアロゾルの変動を導出する。また、気象庁・環境省の地上観測データを解析し、日本のエアロゾルの約半世紀の変動を導出する。そして、これらの結果を用いて、地球システムモデルの検証を行う。さらに、活動自粛期間の結果を抽出し、長期変動からの偏差としてコロナ禍の影響を評価する。

Outline of Final Research Achievements

Long-term changes in aerosols in East Asia were investigated using various ground and satellite observation data. The results showed stagnation from 1933 to 1950, an increase from 1950 to 1970, stagnation from 1970 to 1995, and a decrease after 1995. The composition analysis of aerosols indicated that the decline in 2000s was due to a decrease in water-soluble and light-absorbing particles. We confirmed that these long-term changes were reproduced by the Earth System Model, ESM-MRI 2.0.
The impact of the activity suppression due to COVID-19 on aerosols was investigated using long-term observation data. Aerosols decreased at Sapporo and Fukuoka in the early stages of the infection spread, but no significant changes were observed at other sites.

Academic Significance and Societal Importance of the Research Achievements

本研究によって、東アジアの数十年規模のエアロゾルの長期変動を明らかし、経済活動や大気汚染問題に関する規制との関係性を示すことができた。そして、IPCC報告書に貢献を続けている気象研究所の地球システムモデルの再現性を確認し、エミッションインベントリに関わる問題点を指摘することができた。また、コロナ禍による経済活動自粛の影響について、長期変動の観点から明らかにすることができた。本研究に得られた観測に基づいた半世紀以上の長期変動の成果は、他に類を見ないものであり、学術的意義が高い。また、社会活動との関連性を明らかにしており、社会的意義が認められる成果と言える。
