Outline of Annual Research Achievements

MOSAiC国際チームの大気び海洋グループでは、MOSAiCの概要論文を共著でそれぞれ出版した。個別研究では、MOSAiCの融解期に取得した北極点付近の海氷-海洋境界層における海洋物理データを解析し、乱流混合と海氷量変動に関する査読つき論文を投稿した(改訂版提出済)。また、ノルウェー極地研(NPI)のチームと共同で、多層流向・流速計(ADCP)のデータから海氷直下の乱流エネルギーを自動で観測する技術とその数値処理に関する手法の開発を進めている。さらに、北極点近くの多年氷に出来たリード(水路)内の淡水層について、MOSAiCで採取した観測サンプルの酸素安定同位体比や二酸化炭素濃度の分析から、リード内の淡水層は積雪融解水ではなく、海氷融解水が卓越することが明らかとなった。また、リード表面の二酸化炭素濃度は大気に対して未飽和となり、リードは大気中二酸化炭素の強い吸収源となることが明らかになった。
MOSAiC期間中にニーオルスンで実施した雲粒子センサー(CPS)ゾンデデータについて、雲粒の数濃度、有効粒径半径、雲水量などの値を算出する補正方法の開発を行った(国際誌発表済)。また、研究船「みらい」で実施したCPSゾンデの結果を用い、海洋起源のエアロゾルが氷雲の雲核となることを示し、海氷減少が雲の形成過程に影響を与える可能性を提唱した(国際誌発表済)。
ラジオゾンデ観測を補完する観測システムとして期待されているドローンを用い、高精度な気象プロファイリングを安価に実現するための研究開発をおこなった。具体的には、市販のドローンを用い、機体が作り出す排熱や風の場を室内実験で精査し、気象センサーを搭載する場所の検討、気象センサーの放射シールドの作成、野外でのラジオゾンデとの比較観測などを通じ、適切な設定を施せばラジオゾンデ並みの精度で対流圏下層の気象観測が実現することを実証した(国際誌発済)。
