摘要
新型虚拟试验对虚拟大气环境提出了更高的要求,例如提供包含多种大气参数的复合大气环境、提高大气环境数据的易用性及可重用性。针对这些需求,提出了基于MM5(The Fifth-Generation Mesoscale Model)模式和SEDRIS(Synthetic Environment Data Representation and Interchange Specification)规范的虚拟大气环境构建方法。利用MM5模式,生成任意地域、任意尺度的复合大气环境的原始数据。根据大气数据网格性的特点及其动态时空关系,选取SEDRIS规范合适的DRM(Data Representation Model)类、SRM(Spatial Reference Model)模板以及EDCS(Environment Data Coding Specification)词典,对原始数据进行了表示方法的规范化,生成了符合SEDRIS标准的STF(SEDRIS Transmittal Format)格式的虚拟大气环境数据,具有逼真度高、易用性强和可重用性高等优点。
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.
