Despite several decades of successful Antarctic aviation, centered upon flight operations in the McMurdo (Phoenix Field, Ross Island; RsI) area, systemized description of radar observations such as are normally found essential in operational aviation settings are notably lacking. The Ross Island region of Antarctica is a topographically complex region that results in large variations in the mesoscale high wind and precipitation features across the region. The goals of this project are to increase the understanding of the three-dimensional structure of these mesoscale meteorology features. Of particular interest are those features observed with radar signals.This project will leverage observations from the scanning X-band radar installed during the AWARE field campaign in 2016 and the installation of an EWR Radar Systems X-band scanning radar (E700XD) to be deployed during the 2019-20 field season, at McMurdo. Several science questions and case studies will be addressed during the season.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

尽管几十年来南极航空取得了成功，主要集中在麦克默多（罗斯岛菲尼克斯机场; RsI）地区的飞行作业上，但对雷达观测的系统化描述，如通常发现在航空作业环境中必不可少的，却明显缺乏。南极洲罗斯岛地区是一个地形复杂的地区，导致整个地区的中尺度大风和降水特征变化很大。 该项目的目标是增加对这些中尺度气象学特征的三维结构的了解。该项目将利用2016年AWARE野外活动期间安装的X波段扫描雷达的观测结果，以及将于2019-20年野外季节在麦克默多安装的EWR雷达系统X波段扫描雷达（E700 XD）的观测结果。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估来支持。
