墨脱微雨雷达数据（2020-2022）

墨脱K波段微雨雷达是德国METEK公司生产的小型垂直指向雷达，采用连续调频技术（FMCW）, 发射功率仅为50mW ，发射机和接收机共用直径仅为0.6m的天线。微雨雷达可以获得降水粒子的功率谱密度，根据粒子下落速度与直径的经验公式，反演出粒子的雨滴谱、雨强、液态水含量等的垂直廓线。该设备于2020年7月开始连续观测，除了因电力、网络和通讯等因素引起的观测中断外，微雨雷达数据基本连续。每天数据自动存在一个文件夹下，完整的观测数据文件为24个，每小时一个，每天数据量大约20M，数据格式为netcdf格式。观测期间数据的时间分辨率为1分钟，库数为128个，分辨率为30 m/50m。

The Motuo K-band Micro Rain Radar is a small vertically pointed radar manufactured by the German company METEK. It adopts Frequency Modulated Continuous Wave (FMCW) technology, with a transmit power of only 50 mW, and its transmitter and receiver share an antenna with a diameter of only 0.6 meters. The micro rain radar can obtain the power spectral density of precipitation particles, and retrieve the vertical profiles of raindrop size distribution, rainfall intensity, liquid water content and other related parameters based on the empirical formula relating the falling velocity and diameter of particles. This equipment started continuous observations in July 2020, and the micro rain radar data is basically continuous except for observation interruptions caused by factors such as power, network and communication issues. Data is automatically stored in one folder every day, with a total of 24 complete observation data files (one per hour). The daily data volume is approximately 20 MB, and the data format is netCDF. During the observation period, the temporal resolution of the data is 1 minute, the number of range bins is 128, and the range resolution is 30 m/50 m.
