Outline of Final Research Achievements

Albedo of the snow surface, which is controlled by grain size at the surface, is the important factor for monitoring of the cryosheric environments. In this study, we compared several snow grain size measurement methods and cleared the properties of each method. Based on these results, we developed a new device to measure grain size in the field with easier than the existing methods. Actually, we carried out field observations in the Greenland with this new device and had good results. We improved the snow cover model (SMAP) using field observation and cold room experiment results, then connected SMAP with the regional meteorological model for simulation of the recent surface mass balance change in Greenland. We also developed a new model to simulate the optical characteristics of snow accurately. Using this model, we indicated the clear recent trend of increasing the grain size during the summer season in Greenland using the satellite data.

Academic Significance and Societal Importance of the Research Achievements

雪氷圏は温暖化の影響を他の地域よりも受けやすいと言われている．本研究で開発した積雪粒径をフィールドで手軽に測定できる装置，高度化された積雪変質モデル，積雪の光学的特性を正確に計算可能なモデルにより，従来よりも精度よく雪氷圏の変動をモニタリングできるようになることが期待される．またそのようなモニタリングを通じて，温暖化の影響を正確に把握することで，より正確な将来予測が可能となることに貢献する．
