Outline of Final Research Achievements

We have established methods for isotope proxy data assimilation, which constrains the annual mean values of surface air temperature, precipitation, and sea surface temperature, and for paleo-weather data assimilation, which constrains the three-dimensional state of major atmospheric elements such as wind speed, air temperature, and water vapor content. In the study using the isotope proxy data assimilation method, it became possible to estimate the annual variability of the global distribution of surface temperature and precipitation from 850 to 2000, and in the study using the paleo-weather data assimilation method, it was possible to improve the estimation performance of state variables by assimilation using Gaussian transformation. With these results, we can say that we are ready to construct the Millennium Atmospheric Reanalysis.

Academic Significance and Societal Importance of the Research Achievements

この研究では、過去の気候の情報を保存している自然界に存在する様々な物質に含まれる同位体比と、人類が書き残した古文書に記載されている過去の天気の情報とを、最先端のコンピュータシミュレーションと融合し、地球表層の状態を詳細かつ正確に復元するための手法を開発しました。過去の気候変動がどうなっていたのかを詳細に知ることで、将来の気候変動がどのようになるかを予測することがより正確になると期待されます。
