GPM GROUND VALIDATION AUTONOMOUS PARSIVEL UNIT (APU) IPHEx V1

The GPM Ground Validation NASA Autonomous Parsivel Unit (APU) IPHEx dataset was acquired by multiple parsivel instruments during the GPM Integrated Precipitation and Hydrology Experiment (IPHEx), which took place in western North Carolina. IPHEx sought to characterize warm season orographic precipitation regimes, and the relationship between precipitation regimes and hydrologic processes in regions of complex terrain. The APU, an optical disdrometer based on single particle extinction, measures particle size, and fall velocity. ASCII encoded data files contain information on the drop size distribution and integral precipitation parameters such as precipitation rate, reflectivity, and mass-weighted mean diameter.

GPM 地面验证 NASA 自主式 Parsivel 单元（APU）IPHEx 数据集是在 GPM 集成降水和水利实验（IPHEx）期间，通过多台 Parsivel 仪器获取的。该实验于北卡罗来纳州西部进行，旨在描述暖季地形降水机制，以及降水机制与复杂地形区域水文过程之间的关系。APU 是一种基于单粒子消光的光学谱仪，用于测量粒子大小和下落速度。ASCII 编码的数据文件包含了液滴尺寸分布以及积分降水参数，如降水率、反射率和质量加权平均直径等信息。
