Abstract To address the teaching challenge posed by the limitations of traditional experimental techniques in dynamically analyzing the atmospheric transport and transformation of trace substances,a numerical simulation-based instructional approach using a chemical box model was developed.The DSMACC model was employed as the teaching platform,and its framework and operational workflow were systematically analyzed.Simulation-based teaching cases were designed for key atmospheric chemical processes,including tropospheric ozone formation kinetics,radical cycling mechanisms,and the nonlinear response of ozone to its precursors.By leveraging flexible parameter configuration and user-friendly operation,this approach enables multidimensional and dynamic visualization of complex chemical processes,effectively overcoming the dual constraints of traditional experimental teaching in reaction system construction and process monitoring.Teaching practice demonstrates that the deep integration of model simulations with theoretical instruction not only deepens students’ understanding of the complex atmospheric chemistry but also enhances their programming skills,ability to analyze complex problems,and proficiency in model application,establishing an innovative teaching mode for reforming atmospheric chemistry curricula.
