GPM Ground Validation Micro Rain Radar (MRR) OLYMPEX V1

The GPM Ground Validation Micro Rain Radar (MRR) OLYMPEX dataset was gathered during the Global Precipitation Measurement (GPM) Ground Validation OLYMPEX field campaign held at Washington’s Olympic Peninsula from October 31, 2014 through May 22, 2016. The dataset contains measured and derived data from MRR instruments placed in four separate locations within the study region. 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. Data files are available in ASCII data format.

本数据集系在2014年10月31日至2016年5月22日期间，于华盛顿州奥林匹克半岛举办的全球降水测量（GPM）地面验证OLYMPEX野外考察活动中收集所得。数据集汇聚了安置于研究区域四个不同地点的GPM地面验证微雨雷达（MRR）所测得的原始数据及其衍生数据。该MRR为一款Biral/Metek品牌、24 GHz（K波段）垂直向频率调制连续波（FM-CW）雷达，通过测量信号的后向散射，可导出多普勒频谱、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等参数。数据文件以ASCII格式提供。
