Abstract: 低温科学研究所で行われた積雪断面観測の記録は約50 年に及ぶ世界でもまれに見る貴重なデータセットである.また,その長い歴史の中で,2000 年代以降の断面観測は詳細な放射観測とリンクし,積雪に関係する物理プロセスモデル開発という新たな利用価値が見出されてきた.その背景には,地球温暖化の影響が雪氷圏で顕著に現れるという事実がある.今後,雪氷圏変動を精度良く予測するためには雪氷面における放射収支,熱収支,質量収支などの物理プロセスの更なる理解と精緻なモデル化が必要である.本論文ではこれらの観測結果及びそれに基づいて開発された積雪アルベド物理モデルや積雪変質モデルの検証結果についてレビューし,今後の展望を議論する.
Long-term record of snow pit observation conducted by Institute of Low Temperature Science (ILTS) at Sapporo for 50 years is an important and rare data set in the world. Snow pit observations after the 2000 s in the long history were linked with detailed radiation observations, and both of them were newly utilized for the purpose of physically based process modeling on snow. The background for that is related with the fact that effect of global warming is greater in cryosphere. To predict the future change in cryosphere accurately, further understanding and elaborate modeling of physical processes including radiation budget, heat budget and mass balance at snow surface are needed. This paper reviews the studies of snow physical/chemical properties and albedos observed at a study plot of ILTS and the validations of physically based albedo model and snow metamorphism model developed with those data, and the future issues are finally discussed.
