Abstract: The new virtual test for virtual atmosphere environment puts forward higher requirements, such as providing complex atmospheric environment which includes a variety of atmospheric parameters and improving usability and reusability of atmospheric environment data. A method to construct virtual atmospheric environment based on MM5 and SEDRIS was proposed which met the above demands. The original data of complex atmospheric environment in any region and scale was generated by using MM5 model. According to the characteristics as well as the dynamic relationship between time and space of grid of atmospheric data, SEDRIS was selected to regulate appropriate DRM class, SRF model and EDCS dictionary. The normative of presentation of original data was realized, which generated the virtual atmospheric environment data of STF format conforming to SEDRIS standards, which guarantees high fidelity, usability and reusability.

Key words: virtual test, atmosphere environment, MM5, SEDRIS
