GPM Ground Validation Autonomous Parsivel Unit (APU) OLYMPEX V1

The GPM Ground Validation Autonomous Parsivel Unit (APU) OLYMPEX dataset was collected during the OLYMPEX field campaign held at Washington's Olympic Peninsula during the intense observation period of November 2015 to the end of January 2016. The dataset consists of data collected by 16 APUs. 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. This APU dataset provides precipitation data including precipitation amount, precipitation rate, reflectivity in Rayleigh regime, liquid water content, drop diameter, and drop concentration. Data are available in ASCII format.

GPM 地面验证自主 Parsivel 单元（APU）OLYMPÉX 数据集是在 2015 年 11 月至 2016 年 1 月底于华盛顿奥林匹克半岛进行的 OLYMPÉX 实地考察期间收集的。该数据集由 16 个 APU 收集的数据组成。APU 是一种基于单粒子消光的光学激光谱仪，用于测量粒子大小和沉降速度。它由德国 OTT 开发的 Parsivel2 和阿拉巴马大学开发的辅助硬件组成。此 APU 数据集提供了包括降水量、降水速率、拉伊利态下的反射率、液态水含量、液滴直径和液滴浓度在内的降水数据。数据以 ASCII 格式提供。
