Summary:The Models-3 Community Multi-scale Air Quality modeling system (CMAQ)coupled with the Regional Atmospheric Modeling System (RAMS)is applied to East Asia to study the transport and photochemical transformation of tropospheric ozone in March 1998．The calculated mixing ratios of ozone and carbon monoxide are compared with ground 1evel observations at three remote sites in Japan and it is found that the model reproduces the observed features very well．Examination of several high episodes of ozone and carbon monoxide indicates that these elevated levels are found in association with continental outflow，demonstrating the critical role of the rapid transport of carbon monoxide and other ozone precursors from the continental boundary layer．In comparison with available ozonesonde data，it is found that the model-calculated ozone concentrations are generally in good agreement with the measurements，and the stratospheric contribution to surface ozone mixing ratios is quite limited．
