Outline of Final Research Achievements

We have developed a high-performance radioactive-tracer advection-diffusion-deposition model by improving the JMA operational numerical weather prediction (NWP) model in this research program. Combining the models, an ensemble Kalman filter, and the JMA operational observation dataset (i.e., data assimilation), we successfully produced a 3-km gridded meteorological analysis and its ensemble perturbation members, of which horizontal resolution is finer than the JMA operational NWP. The advection-diffusion-deposition simulations with the ensemble meteorological dataset enabled the Fukushima-nuclear-accident atmospheric pollution to be simulated at the highest precision level and the simulation error to be estimated by the ensemble analysis. We achieved the original goals of this research program almost completely.
