| Outline of Final Research Achievements |
This study aims to develop a process-based crop yield prediction system using satellite observations. Through a series of system developments, we have obtained following achievements: (1) A hydrological land data assimilation system was newly developed. (2) A real-time hydrological simulation system was developed. The system stably ran over two years. (3) Ensemble-based model parameter estimation method was explored. (4) New data assimilation methods were explored mathematically on a covariance inflation method of the ensemble-based data assimilation, and a treatment of observations with the non-Gaussian error statistics.
