摘要
现有标准格式雷达基数据解析工具在设计上存在通用性和抽象性不足的问题,不便于雷达数据的解析和处理。为了解决这个问题,本文基于Unidata的CDM(Common Data Model),设计和构建了中国天气雷达基数据模型,在数据模型层面实现了对天气雷达标准格式基数据的访问,并以Unidata开源的NetCDF Java库和IDV(Integrated Data Viewer)可视化软件为基础,形成了一套基于CDM的天气雷达标准格式基数据内容提取和可视化分析工具。本研究以广州雷达新旧两种格式基本反射率数据对比为例,展示了研究成果在多普勒天气雷达标准格式基数据评估中的应用。结果表明:本研究成果方便了雷达标准格式基数据的使用,对雷达标准格式基数据的业务应用起到了促进作用。本研究成果亦可应用于雷达基数据处理与分析相关的实际业务和科研工作中,为雷达资料的应用提供基础支持。
The existing China Weather Radar Standard Format Base Data analysis tools lack sufficient generality and abstraction in design, which is not convenient for radar data analysis and processing. In order to solve this problem, this paper designs and builds the China Weather Radar Base Data Model based on Unidata’s CDM(Common Data Model) and realizes the access to the Weather Radar Standard Format Base Data at the data model level. Based on the open-source Unidata’s NetCDF Java library and IDV visualization software, a set of Weather Radar Standard Format Base Data content extraction and visual analysis tools based on CDM are formed. As a valuable case, the comparisons of the new and old basic reflectivity data of Guangzhou radar for the evaluation of Doppler Weather Radar Standard Format Base Data are discussed, addressing a significant example. It shows that our researches facilitate the use and promote the operational application of Radar Standard Format Base Data. The research results can also be applied to the operational and scientific research related to Radar Base Data processing and analysis and provide basic support for the application of radar data.
