GPM Ground Validation Autonomous Parsivel Unit (APU) Wallops Flight Facility (WFF) V1

The GPM Ground Validation Autonomous Parsivel Unit (APU) Wallops Flight Facility (WFF) dataset consists of precipitation data including precipitation amount, precipitation rate, reflectivity in Rayleigh regime, liquid water content, drop diameter, and drop concentration obtained from six Autonomous Parsivel Units (APUs) positioned at the Wallops Flight Facility (WFF) in support of the Global Precipitation Mission (GPM). The APU is an optical laser-disdrometer based on single particle extinction that measures particle size and fall velocity. It consists of the Parsivel2 developed by OTT in Germany and supporting hardware developed by University of Alabama. Data are available in ASCII format for the period of May 6, 2013 through October 9, 2014.

全球降水任务（GPM）地面验证自动帕西维尔单元（APU）沃尔lops飞行设施（WFF）数据集，包含了从六个位于沃尔lops飞行设施（WFF）的自动帕西维尔单元（APU）获取的降水数据，包括降水量、降水速率、瑞利状态下的反射率、液态水含量、液滴直径和液滴浓度。APU是一种基于单粒子消光的光学激光滴谱仪，用于测量粒子大小和下降速度。该单元由德国OTT开发的Parsivel2和阿拉巴马大学开发的辅助硬件组成。数据以ASCII格式提供，时间跨度为2013年5月6日至2014年10月9日。
