摘　　要：漠河站(53.5°N,122.3°E)全天空无线电流星雷达为宽波束全天空干涉雷达,通过流星体进入地球大气烧蚀后的流星尾迹对电波的反射回波,探测流星体信息及70-110公里高度区域大气信息。本数据集包含2018年全年漠河站全天空无线电流星雷达观测的雷达观测数据和雷达分析数据。雷达观测数据包含流星尾迹的距离、到达角、径向速度、回波信号强度及衰减时间和扩散系数等参量;雷达分析数据是由雷达观测数据经分析处理后得到的大气风场数据。漠河站流星雷达数据集可以用来开展中层低热层区域大气动力学以及中性大气与电离层耦合等方面的研究。The meteor radar at Mohe station(53.5°N,122.3°E)is an all-sky interferometry radar with wide beam.It can detect meteor trails left by meteoroids when entering and ablating in the Earth atmosphere at altitudes between 70 km and 110 km.The dataset from Mohe meteor radar in 2018 consists of radar observation data and radar analyzed data.Radar observation data includes range,angle of arrival,radial velocity,signal power,decay time,diffusion coefficient of meteor trails,etc.Radar analyzed data refers to the atmospheric wind field data obtained by analyzing and processing radar observation data.The dataset from Mohe meteor radar can be used for studies on atmosphere dynamics in the mesosphere and lower thermosphere(MLT)region and the coupling between atmosphere and ionosphere.
