Ground-based radar-sounding surveys derived from US radar sounders (JARE60)

Ground-based radar-sounding surveys were carried out at southern area from Dome Fuji station during the period from 18 december 2018 to 8 January 2019. We used two radar systems as follows. (1) The multi-channel, VHF wideband radar system developed by the University of Kansas for fine-resolution measurements of the interior and based of ice sheets, and (2) the ultra-wideband microwave radar system developed by the University of Alabama for snow and firn measurements. Distance of the survey is 1340km at the southern area from Dome Fuji station, and 546km from the base camp of the JARE60 traverse campaign to ARP2.本数据集相关的地面雷达探测工作于2018年12月18日至2019年1月8日期间，在富士圆顶（Dome Fuji）站南侧区域开展。本次探测采用两套雷达系统，具体如下。（1）由美国堪萨斯大学（University of Kansas）研发的多通道甚高频（VHF）宽带雷达系统，用于冰盖内部与基底的高分辨率探测；（2）由美国阿拉巴马大学（University of Alabama）研发的超宽带微波雷达系统，用于积雪与粒雪层的探测。本次探测总里程分为两部分：富士圆顶（Dome Fuji）站南侧区域的探测里程达1340千米，JARE60横穿科考队的大本营至ARP2的探测里程为546千米。
