Eredar measurements of Erebus lava lake level (NERC Grant NE/N009312/1)

Surface level measurements of the Erebus volcano lava lake, Antarctica. Surface level was measured from a site at the crater rim using the Eredar radar system, a ground-based X-band FMCW radar (described in detail here: https://doi.org/10.1029/2018GL079177). The dataset contains a single continuous measurement period from 2016 (all times in UTC): 19 Dec 00:35 -> 19 Dec 19:21 Measurements were taken at a rate of ~0.25 Hz, using a 0.16 s 400 MHz bandwidth Linear Frequency Modulated chirp centred at 10.4 GHz, with 10 chirps being averaged for each measurement.本数据集涵盖南极洲埃里伯斯火山熔岩湖的地表高程测量数据。数据采集于火山口边缘的观测站点，采用Eredar雷达系统完成，该系统为地基X波段调频连续波（FMCW）雷达，其详细技术说明可参见文献：https://doi.org/10.1029/2018GL079177。本数据集包含一段2016年的连续测量时段（所有时间均采用协调世界时（UTC））：2016年12月19日00:35至2016年12月19日19:21。数据采集速率约为0.25 Hz，单次测量采用时长0.16秒、带宽400 MHz、中心频率10.4 GHz的线性调频啁啾信号，且对每次测量对应的10个啁啾信号进行平均处理。
