摘要
为了更好处理和应用诸如气象数值预报产品等非结构化的气象大数据,基于NetCDF技术实现了全序列气象数值预报产品原始格式解码、数据的格式转换以及生成符合各类数值预报产品特征的NetCDF格式的存储库,并将转换和重新组织的数值预报产品数据实时存储到相应的NetCDF库文件中;基于NCL(The NCAR Command Language)编程语言读取NetCDF库文件中的数据生成精度高、内容展现丰富的数值预报图形产品,并提供给业务用使用,业务运行结果表明大数据处理技术的引入对气象大数据在业务中的应用具有一定的促进作用。
In order to better processing and applications the non-structured meteorological data, such as numerical weather fore-cast products. Based on technology of NetCDF, the system achieve data decoding and data format conversion of original format of numerical weather prediction products, then generate a NetCDF format repository which has the characteristics of the various of numerical forecast products. Based on NCL (The NCAR Command Language) programming language to generate high preci-sion and rich content of the numerical prediction graphics products by reading NetCDF repository .the results show that the in-troduction of a large data processing techniques has a certain role in promoting the applications for meteorological big data.
