Internet-2和有效的数据压缩技术的出现，促进了从天气监视雷达-1988多普勒（WSR-88 D）网络到用户的真实的时间的基础级雷达数据的经济传输。由于雷达球坐标系的固有性和数据量的巨大性，使得雷达数据处理成为一项艰巨的任务，特别是当需要多部雷达的数据来生产复合雷达产品时。本文研究了几种将多雷达反射率场重新映射和组合到具有高空间（≤1 km）和时间（≤5 min）分辨率的统一三维笛卡尔网格上的方法。本研究的目的是找到一种分析方法，保留原始反射率数据的物理特性，最小的平滑或引入的分析文物。此外，该方法需要在计算上对于潜在的操作应用是高效的。适当的分析可以为用户提供高分辨率的反射率数据，...
Abstract The advent of Internet-2 and effective data compression techniques facilitates the economic transmission of base-level radar data from the Weather Surveillance Radar-1988 Doppler (WSR-88D) network to users in real time. The native radar spherical coordinate system and large volume of data make the radar data processing a nontrivial task, especially when data from several radars are required to produce composite radar products. This paper investigates several approaches to remapping and combining multiple-radar reflectivity fields onto a unified 3D Cartesian grid with high spatial (≤1 km) and temporal (≤5 min) resolutions. The purpose of the study is to find an analysis approach that retains physical characteristics of the raw reflectivity data with minimum smoothing or introduction of analysis artifacts. Moreover, the approach needs to be highly efficient computationally for potential operational applications. The appropriate analysis can provide users with high-resolution reflectivity data that ...
