GPM Ground Validation Micro Rain Radar (MRR) LPVEx V1

The GPM Ground Validation Micro Rain Radar (MRR) LPVEx dataset was collected during the Global Precipitation Measurement (GPM) mission Ground Validation Light Precipitation Validation Experiment (LPVEx) field campaign. The LPVEx field campaign took place around the Gulf of Finland in September and October of 2010. The goal of the campaign was to provide additional high altitude, light rainfall measurements for the improvement of GPM satellite precipitation algorithms. The MRR is a Biral/Metek 24 GHz (K-band) vertically oriented Frequency Modulated Continuous Wave (FM-CW) radar that measures signal backscatter from which Doppler spectra, radar reflectivity, Doppler velocity, drop size distribution, rain rate, liquid water content, and path integrated attenuation are derived. The dataset contains measured and derived data from MRR instruments placed at four remote sites (Jarvenpaa, Emasalo, Harmaja, and the research vessel Aranda). Data files are available in ASCII data format.

GPM 地面验证微雨雷达（MRR）LPVEx 数据集是在全球降水测量（GPM）任务地面验证轻降水验证实验（LPVEx）野外作业期间收集的。LPVEx 野外作业于 2010 年 9 月至 10 月在芬兰湾周边地区进行。此次作业的目的是为 GPM 卫星降水算法的改进提供额外的中高空、轻量级降雨测量数据。MRR 是一款 Biral/Metek 品牌、24 GHz（K波段）垂直安装的频率调制连续波（FM-CW）雷达，它能测量信号的回波散射，并据此推导出多普勒频谱、雷达反射率、多普勒速度、液滴尺寸分布、降雨速率、液态水含量以及路径积分衰减。该数据集包含了放置在四个远程站点（Jarvenpaa、Emasalo、Harmaja 以及研究船 Aranda）的 MRR 仪器的测量和推导数据。数据文件以 ASCII 数据格式提供。
