Modern simulation applications need physically consistent atmospheric environment representation. The consistency, standardized and effective atmospheric environment data representation are critical for simulation applications, it is the basis of realizing interoperability and reusability of simulation. In this paper, considering the characteristics of atmospheric environment simulation data and application requirements of simulation, atmospheric environment five dimensional representation model is designed, five dimension rectangular grid form of atmospheric environment simulation results are expressed, to regulate the level of resolution, vertical stratification, time step and characteristic parameters, can reflect truly the characteristics of temporal and spatial variations of the actual atmospheric environment. Atmospheric environment simulation data is stored and managed effectively through five dimensional representation model, atmospheric environment simulation model base is generated. The reusability of the simulation model is improved.
