介绍了一种处理通过平面位置指示器 (PPI) 扫描收集的极化雷达数据并以时间高度格式显示这些数据的新方法。柱状垂直剖面 (CVP) 方法使用通过多次仰角扫描收集的雷达数据（仅限于相对于雷达的范围和方位角的设定区域内的数据）来创建代表该有限空间区域的极化雷达数据的垂直剖面。该技术与文献中现有的其他技术进行了比较，并讨论了各种应用。对在两次野外活动期间采样的两个中尺度对流系统的层状雨区域内创建的 CVP 进行偏振冰微物理反演，其中 CVP 跟踪研究飞机的轨迹。飞机现场数据与微物理检索数据相匹配，并且这些检索的准确性与文献中的其他检索技术进行了测试。
A novel way to process polarimetric radar data collected via plan position indicator (PPI) scans and display those data in a time–height format is introduced. The columnar vertical profile (CVP)methodology uses radar data collected via multiple elevation scans, limited to data within a set region in range and azimuth relative to the radar, to create vertical profiles of polarimetric radar data representative of that limited region in space. This technique is compared to others existing in the literature, and various applications are discussed. Polarimetric ice microphysical retrievals are performed on CVPs created within the stratiform rain region of two mesoscale convective systems sampled during two field campaigns, where CVPs follow the track of research aircraft. Aircraft in situ data are collocated to microphysical retrieval data, and the accuracy of these retrievals is tested against other retrieval techniques in the literature.
