本年度の繰り越し分の経費を用いて，イオ火山の活発化に伴うイオプラズマトーラスの高温電子輸送のパラメタ特定，とくに朝夕非対称性について議論を深めることができた．
具体的には，ひさき衛星のデータの中から，５つのイオ火山イベントに関連するデータを抽出し，それらに対してスペクトルフィッティング手法を通してプラズマの密度および温度を導出する手法を確立した．これまでは，頻度の低い高分解モードでのスペクトルにしか適応できなかったこのパラメタ導出を，広視野（低分解能）モードのデータにも適用可能になる手法を確立したことにより，プラズマパラメタの導出を時間軸に拡張することに成功した．
NASAのJuno探査機の研究チームのその場観測データと，米国コロラド大学の研究チームが開発しているモデルを組み合わせることで，ひさき衛星のデータから導出したパラメタとの整合性を確認できた．ただし，NASA/Juno探査機の高エネルギー電子やイオン観測装置などによる，木星内部磁気圏のその場観測データの解析に関しては，当初想定していたほどの進捗は見られなかった．これは主にCOVID-19による海外渡航の制限が主な原因であるが，今後は遠隔体制でも効率よくデータ解析できるシステムを構築する．また，小研究会の開催などを通して引き続き米国の研究チームと密に連絡を取り合うことで，校正データの共有などを高頻度で進める．なお，今年度の研究成果として国際学術論文誌２編と博士論文１件，修士論文４件が発表された．
