Outline of Research at the Start

北極海氷縮小によって大気-陸域水循環が大きく変動する北ユーラシア永久凍土域を対象に、多圏(大気・陸域・海洋)にまたがり起源別の水の動きを追跡する水循環統合モデルを開発し、衛星リモートセンシングデータを活用して湛水域時系列マップと植生変化域時系列マップを作成する。それらを用いて、並行して開発中の陸域生態系物質循環モデルにより、温室効果気体の放出・吸収量の時系列マップを作成する。北ユーラシアの複数点で温室効果気体フラックス観測を行い、得られた観測データを機械学習によるデータ駆動型経験モデルを用いて広域化し、温室効果気体の放出・吸収量の時系列マップの検証を行う。

Outline of Final Research Achievements

We clarified recent variations in the atmospheric-terrestrial water cycle, vegetation conditions, permafrost conditions, and greenhouse gas emission and/or absorption in northern Eurasia. We developed an integrated water cycle model to track the movement of water by source. And by utilizing satellite remote sensing data, we finally created time-series maps of inundation areas and areas of vegetation change in the region. Modulations in the atmospheric-terrestrial water cycle were found during the snowmelt season and the late warm season. It was also found that climate changes during these seasons have a significant impact on the amount of carbon dioxide emission and/or absorption in the region.

Academic Significance and Societal Importance of the Research Achievements

起源別の水の動きを追跡する水循環統合モデルの開発が進むとともに、北ユーラシアにおける湛水域と植生変化域の時系列マップが創出された。融雪期や暖候期後期における大気-陸域水循環の変調や気候変化が、当該領域における二酸化炭素の放出・吸収量に大きく影響することを見出した。これらの研究成果はハイインパクトな国際学術誌に数多く掲載されたため、今後、北ユーラシアを含む北極域における気候変化予測の不確定性の改善に大きく貢献するであろう。
