GPM GROUND VALIDATION ENVIRONMENT CANADA (EC) MICRO RAIN RADAR (MRR) GCPEX

The GPM Ground Validation Environment Canada (EC) Micro Rain Radar (MRR) GCPEx V2 dataset was collected from the Micro Rain Radar (MRR) during the GPM Cold-season Precipitation Experiment (GCPEx) in Ontario, Canada during the winter season 2012. GCPEx addressed shortcomings in the GPM snowfall retrieval algorithm by collecting microphysical properties, associated remote sensing observations, and coordinated model simulations of precipitating snow. Operating at 24 GHz the MRR, a vertically pointing Doppler radar, retrieved quantitative rain rates, drop size distributions, radar reflectivity, and fall velocities on vertical profiles up to several kilometers above the unit. The MRR used during GCPEX is the second generation of the instrument manufactured by METEK (URL: http://metek.de/product/mrr-2/). Version 2 of this dataset became active on April 30, 2015.

GPM 地面验证环境加拿大（EC）微雨雷达（MRR）GCPEx V2 数据集系在加拿大安大略省2012年冬季GPM 冷季降水实验（GCPEx）期间，利用微雨雷达（MRR）收集而成。GCPEx 实验旨在解决GPM 雪量检索算法的不足，通过收集微物理特性、相关遥感观测以及协调的降雪模型模拟。该MRR 雷达工作于24 GHz，为一部垂直指向的多普勒雷达，能够从数公里高空对单位面积上方的垂直剖面进行定量降雨率、液滴尺寸分布、雷达反射率和下降速度的测量。GCPEx 中使用的MRR 为METEK（网址：http://metek.de/product/mrr-2/）制造的仪器第二代产品。本数据集的V2版本自2015年4月30日起生效。
