Outline of Annual Research Achievements

(1) 地上観測：北西グリーンランド氷床・カナック氷帽上SIGMA-Bサイトに設置された自動気象観測装置観測データを用いて熱収支解析を行い、2012年以降の表面融解量の年々変動を調べた結果、融解量が増加した年の気温とアルベドの特徴的な変化を明らかにした。また、2017年に採取した同氷床上SIGMA-Aアイスコア中のd-excessの変動がバフィン湾の海氷面積変動と相関があることを示し、1909年以降の海氷面積変動を復元した。
(2) 衛星観測：積雪粒径に依存して形状が変化するボロノイ・カラム型積雪粒子形状モデルを開発し、全天分光日射計データから、積雪粒径と積雪不純物濃度を推定するアルゴリズムを開発した。このアルゴリズムを用いて衛星データからグリーンランド氷床の積雪物理量を抽出し、また、同衛星データの複数の波長バンドにおける反射率の組み合わせから裸氷域・暗色裸氷域面積変動を抽出した。それらの物理量と表面アルベドとの定量的な関係を明らかにした。
(3) 数値モデリング：極域気候モデルNHM-SMAPを用いて、グリーンランド氷床表面質量収支モデル相互比較プロジェクトGrSMBMIPへの参加、雲放射効果の感度実験、化学輸送過程を組み合わせたNHM-Chemとの結合モデルによる積雪中ブラックカーボン（BC）再現実験等を実施した。CMIP6の枠組みで実施されたモデル相互比較実験（RFMIP, AerChemMIP）において、MRI-ESM2を用いて大気上端における人為起源物質の有効放射強制力を推定し、北極域ではBCは二酸化炭素に次いで二番目に大きい正の有効放射強制力を持つことが明らかとなった。雪氷藻類がもつ色素の波長別吸光係数を考慮した積雪アルベド物理モデルを構築し、藻類によるアルベド低下効果を定量的に求めることが可能となった。
