| Outline of Final Research Achievements |
Three-dimensional atmospheric radiation models were developed on the basis of Monte Carlo method and explicit solution method. The three-dimensional radiation models were applied to the latest cloud-resolving meteorological simulation data. As a result, in the case of open cell cloud and closed cell cloud, differences in solar radiative heating rate at 1-6 K/hr were shown as a function of spatial grid sizes between 100m and 1km. On the other hand, domain-average of the solar radiative heating rate did not depend on spatial resolution, and there were no significant thermo-dynamical differences in domain-average values. Therefore, it is shown that cloud-radiation interaction at cloud-resolving scale might have different property depending on the spatial resolution.
