| Outline of Final Research Achievements |
For better understanding of variation of global water cycle, an integrated surface fresh water flux dataset consisting of newly developed satellite freshwater flux data and improved ocean data assimilation system was developed. The relationship between variations in surface freshwater flux and upper ocean over the past 20 years was investigated using these data sets. Global variation of evaporation and precipitation accompanied by large scale oceanic variations were revealed. Based on open data policy, the data sets were released for use in a wider range of research.
