GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) OLYMPEX V1

The GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) OLYMPEX dataset contains information on individual hydrometeors including their size distribution, terminal fall speed, and total concentration collected during the Global Precipitation Measurement mission (GPM) Ground Validation (GV) Olympic Mountains Experiment (OLYMPEX). The OLYMPEX field campaign took place between November 2015 and January 2016, with additional ground sampling continuing through February 2016, on the Olympic Peninsula in the Pacific Northwest of the United States. The purpose of the campaign was to provide ground-validation data for the measurements taken by instrumentation aboard the GPM Core Observatory satellite. The Two-Dimensional Video Disdrometer (2DVD) data were collected from four sites during the campaign. The dataset files are available from October 31, 2015 through January 17, 2016 (though the exact dates may vary per site) in ASCII-tsv format.

GPM 地面验证二维视频雨滴谱仪（2DVD）OLYMPEX 数据集收录了全球降水测量任务（GPM）地面验证（GV）奥林匹克山脉实验（OLYMPEX）期间收集到的个别降水粒子信息，包括其尺寸分布、终端落速和总浓度。该实验于2015年11月至2016年1月在美国太平洋西北部的奥林匹克半岛进行，并在2016年2月继续进行额外的地面采样。实验旨在为搭载于GPM 核心观测卫星上的仪器所进行的测量提供地面验证数据。在实验期间，二维视频雨滴谱仪（2DVD）数据在四个地点收集。数据集文件以ASCII-tsv格式从2015年10月31日起至2016年1月17日可用（具体日期可能因地点而异）。
