Development of C-band Mobile Polarimetric Radar

共享移动的大气研究和教学（SMART）雷达系统已被用于研究登陆飓风，沙漠微暴流，龙卷风超级单体雷暴和山区雪暴。 在这项重大研究仪器奖中，SMART雷达将被更新，成为该国唯一的移动的极化C波段雷达。 偏振雷达能够垂直和水平地发射和接收，从而改善了对各种属性的测量，例如液滴大小和形状。 作为一个基于卡车的系统，它是完全移动的，可以导航，以遵循瞬态现象或填补其他雷达没有足够的覆盖范围。 硬件升级将包括一个新的接收器，反射器和基座。 PI计划使用雷达进行各种研究，包括：降雨，云微物理学，云带电和风暴动力学。 通过在俄克拉荷马州的试验台上将SMART C波段与现有的S和X波段雷达相结合，可以确定其他研究，以提高对批量极化特征的微物理特性的认识。 PI将向社区提供雷达，作为国家大气科学研究和教育基础设施的一部分。 他们预计，主要学生的参与将对教育产生重大影响。 该项目将在俄克拉荷马州大学和国家海洋和大气管理局（NOAA）的大力协助下向前推进。

The Shared Mobile Atmospheric Research and Teaching (SMART) radar system has been used to study land-falling hurricanes, desert microbursts, tornadic supercell thunderstorms, and mountain snow storms. In this Major Research Instrumentation award, the SMART radar will be updated to become the only mobile, polarimetric C-band radar in the country. Polarimetric radars are capable of transmitting and receiving both vertically and horizontally, leading to improved measurements of various properties, such as droplet size and shape. As a truck-based system, it is completely mobile and can navigate to follow transient phenomena or fill in where other radars do not have adequate coverage. Hardware upgrades will include a new receiver, reflector, and pedestal. The PIs plan to use the radar for various studies, including: rainfall, cloud microphysics, cloud electrification, and storm dynamics. Other studies to improve the knowledge of microphysical properties from bulk polarimetric signatures could be determined by combining the SMART C-band with the available S and X-band radars at a test bed in Oklahoma. The PIs will make the radar available to the community as part of the national infrastructure for atmospheric science research and education. They anticipate a significant impact on education with major student involvement. This project will go forward with significant assistance from the University of Oklahoma and National Oceanic and Atmospheric Administration (NOAA).
