Meteor Head Echo Data from Concurrent Data Collect at RISR-N, JRO, and MHO

Contains data from head echoes observed in the CEDAR 2019 concurrent meteor radar data collect on 2019-10-10 and 2019-10-11 from 9:00-13:00 UTC, at the following facilities: AMISR Resolute Bay Incoherent Scatter Radar North (RISR-N), Jicamarca Research Observatory (JRO), and Millstone Hill Observatory (MHO). Data is saved in the .npz format, which requires Python with the Numpy library to read. The data includes head echo detection rates as a function of time at each facility, and raw data for a subset of head echoes that are included in the analysis of a paper submitted to JGR Space Physics.本数据集收录CEDAR 2019同步流星雷达观测计划中，于2019年10月10日、11日世界协调时（UTC）9:00-13:00时段获取的头部回波（head echoes）观测数据，观测设施包括：AMISR Resolute Bay非相干散射雷达北站（RISR-N）、吉卡马尔卡研究天文台（JRO）以及米尔斯顿山天文台（MHO）。数据以.npz格式存储，需依托搭载NumPy库的Python环境读取。数据集包含各观测设施的头部回波随时间变化的探测率，以及投稿至《Journal of Geophysical Research: Space Physics》（JGR Space Physics）的论文分析所用的部分头部回波原始数据。
