GPM GROUND VALIDATION MICRO RAIN RADAR (MRR) NASA IFLOODS V1

The GPM Ground Validation Micro Rain Radar (MRR) NASA IFloodS dataset was collected by a Micro Rain Radar (MRR), which is a vertically pointing Doppler radar which provided measurements of vertical velocity, drop size distribution, rainfall rate, attenuation, liquid water content, and reflectivity factor during the Iowa Flood Study (IFloodS), which took place in eastern Iowa during the spring of 2013. The goals of the campaign were to collect detailed measurements of precipitation at the Earth's surface using ground instruments and advanced weather radars and, simultaneously, collect data from satellites passing overhead. A total of four MRRs were deployed, each adjacent to a two-dimensional video disdrometer (2DVD). Each MRR-2DVD site had one or more Autonomous Parsivel2 Unit (APU) with tipping bucket rain gauges either collocated or within 4-8 km away. The dataset covers the period of April 11, 2013 through June 16, 2013, but each MRR deployed may not contain data during the entirety of this period.

GPM 地面验证微雨雷达（MRR）NASA IFloodS 数据集由一台微雨雷达（MRR）收集而成，该雷达为垂直指向的多普勒雷达，能够在爱荷华州洪水研究（IFloodS）期间，对垂直速度、液滴尺寸分布、降雨率、衰减、液态水含量和反射率因子进行测量。IFloodS 研究于 2013 年春季在爱荷华州东部进行。此次活动的目标是通过地面仪器和先进的天气雷达收集地球表面降水的详细测量数据，并同时收集从头顶飞过的卫星数据。共部署了四台 MRR，每台 MRR 旁均配置了一台二维视频降水谱仪（2DVD）。每个 MRR-2DVD 站点配备了一台或多台自动 Parsivel2 单元（APU），并配有倾斗式雨量计，这些雨量计要么与 MRR 同位部署，要么位于 4-8 公里范围内。该数据集覆盖了 2013 年 4 月 11 日至 6 月 16 日的期间，但并非所有部署的 MRR 在此期间均包含数据。
