Outline of Final Research Achievements

This research project has two objectives. One is to revive the measurement points along the coastal areas lost due to the Great East Japan Earthquake and to increase the number of measurement points near the central city area, in other words, to redevelop the urban climate observation network. The second is to establish a statistical downscaling method for future urban climate by analyzing and compiling the urban climate observation data accumulated by our laboratory.
We conducted a basic examination for statistical downscaling by combining the measurement data obtained from the urban climate observation network that was reconstructed in the first half of the research period with the past measurement data, as planned. In addition, we submitted the related research results to an international academic journal jointly with a graduate student of our laboratory, which was accepted as a peer-reviewed paper, and we believe we were able to achieve certain results.

Academic Significance and Societal Importance of the Research Achievements

特に東京等の大都市以外で、多点同時測定を可能とする都市気候観測網を長年にわたり実運用している研究機関は、申請者の研究室以外には極めて稀である。また伝統的な観測資料を将来都市気候予測に利活用する研究は国内外を問わずほとんど実施されていない。
申請者は、仙台市総合計画審議会委員、仙台市環境審議会会長、仙台市杜の都の環境をつくる審議会委員を務め、研究成果の社会還元についても実効性は高いと考えている。
