Outline of Annual Research Achievements

本研究では、実大気中の有機エアロゾルの光吸収特性(340-870 nm)に関する新たな定量的な観測的知見（Aerosol Absorption Optical Depth (AAOD; 吸収エアロゾル光学的厚さ)やAbsorption Angstrom Exponent(AAE; 吸収オングストローム指数）)を得るとともに、その光吸収特性の変動要因を明らかにする。独自に世界展開している国際観測網を活用し、エアロゾル特性が明瞭に異なる５つもの主要な観測地点 (日本３地点、タイ１地点、インド１地点)に焦点を当てる。独自の紫外～可視の光吸収特性の長期連続観測技術、および、その変動要因の重要なフィンガープリントをもたらす有機ガス濃度等の観測技術の両方を世界で唯一有する本研究グループのみが可能な研究である。全球化学気候モデル・衛星データも援用した研究体制で相乗的な研究成果を挙げ、有機エアロゾルの光吸収特性に関する研究を推進する。
R03年度は、R02年度に新型コロナウイルスの影響で断片的となった海外サイトでの連続観測を現地協力者の協力などにより再開でき、国外・国内サイトの両方において計画通り複数年にわたるデータを取得できた。各サイトにおいて、AAODとAAEを定量的に見積もり、観測サイト間の相違を明らかにした。このデータとともに観測された有機ガス濃度(ホルムアルデヒドやグリオキサール)やそれらの濃度比、さらには、国際観測網データで精度評価された衛星データ・再解析エアロゾルデータ(MERRA-2)・全球化学気候モデル(CHASER)データを用いて、特にバイオマスバーニングと人為起源の影響を両方受けるインドシナ半島のエアロゾルの各種光学特性の時空間変動を定量的に解明した。このように、有機エアロゾルの光吸収特性に関する研究を推進した。
