Measurements of micro rain radar at AWIPEV, Ny-Ålesund (2017-2021)

The Micro Rain Radar (MRR; type MRR2) - manufactured by Meteorologische Messtechnik GmbH (Metek) - is a vertically pointing frequency modulated continuous wave (FM-CW) Doppler radar operating at 24.1 GHz (K band). The backscattered signal by falling hydrometeors is measured at 32 range gates. This data includes the output of the Improved MRR Processing Tool (IMProToo; Maahn and Kollias, 2012) for the MRR measurements at AWIPEV in 2017-2021. IMProToo provides reliable values of equivalent radar reflectivity Ze, Doppler velocity and spectral width among other variables.微雨雷达（Micro Rain Radar, MRR；型号MRR2）由气象测量技术有限公司（Meteorologische Messtechnik GmbH，简称Metek）制造，是一款垂直指向型调频连续波（frequency modulated continuous wave, FM-CW）多普勒雷达，工作频率为24.1 GHz（K波段）。该设备可在32个距离门处采集下落态水成物粒子产生的后向散射信号。本数据集包含2017至2021年在AWIPEV站点开展的MRR观测经改进型MRR处理工具（Improved MRR Processing Tool, IMProToo；Maahn与Kollias, 2012）处理后的输出结果。IMProToo可输出等效雷达反射率Ze、多普勒速度以及谱宽等多种变量的可靠数值。
