Updated Ice Bottom Elevation for the 2009 Antarctic TO Radar Surveys of West Antarctica

Original processing of the Center for Remote Sensing of Ice Sheets (CReSIS) radar data collected in West Antarctica in 2009 had a time-offset that was not properly accounted for, leading to inaccurate ice-bottom elevations. These files represent the ice bottom reflection after accounting for the time-offset.

2009年于西南极洲采集的冰盖遥感中心（Center for Remote Sensing of Ice Sheets，CReSIS）雷达数据，其原始处理流程未对时间偏移量进行妥善校正，由此导致冰底高程计算结果不准确。本批次文件为已完成时间偏移量校正后的冰底反射数据。
