Abstract
Numerical prediction of climate/weather/environment is an important source for adequate policy making in an era of changing climate. It requires a coupled modeling system, e.g., atmosphere-land surface-chemistry; its performance can be improved through better estimation of parameters and initial conditions. Numerical climate/weather/environment models provide not only their future states but also the analysis data at given grid sizes, which are useful in data void areas. Recent efforts to improve regional climate/weather /environment prediction will be introduced as an integrated approach: estimating optimal parameter values, seeking an optimized set of parameterization schemes, combining optimizations of parameterization schemes and parameter values sequentially(i.e., opti-parameterization), and applying a hybrid ensemble-variational data assimilation through the coupled models (e.g., WRF-Noah-MP and WRF-Chem) and satellite data.
