FRA-JCOPE2再解析データ配布のご案内 再解析データを用いた研究成果 FRA-JCOPE2再解析データの入手方法

By assimilating most available observation data into the JCOPE2 ocean forecast system, the ODPRT team has created the reanalysis data (FRA-JCOPE2) with horizontal high resolution of 1/12 deg. to describe the oceanic variability associated with the Kuroshio-Kuroshio Extension, the Oyashio, and the mesoscale eddies from January 1993 to present time (Miyazawa et al., 2009; 2010). Collaboration with Japanese Fishery Research Agency (FRA) has allowed us to assimilate huge amount of in-situ data around Japan. The assimilation of the in-situ data around Japan is quite effective to capture the Kuroshio frontal waves, the Oyashio intrusion, and the meso-scale eddies. FRA-JCOPE2 reanalysis data are available from the authors by request. The website http://www.jamstec.go.jp/frcgc/jcope/vwp/ provides information about downloading and interactively visualizing the reanalysis data for users.
