GPM GROUND VALIDATION TWO-DIMENSIONAL VIDEO DISDROMETER (2DVD) HYMEX V1

The GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) HyMeX data was collected during the HYdrological cycle in Mediterranean EXperiment (HyMeX), which provided data on raindrop size and precipitation drop size distribution. The 2DVD measured the size of raindrops and also recorded two side view optical images of each raindrop. Used for in situ measurements of precipitation drop size distribution, this instrument recorded orthogonal image projections of raindrops as they crossed its sensing area and provided velocity and shape of individual raindrops.The HyMeX 2DVD data were collected in France and Italy from September 12, 2012 to November 12, 2012. The data are in ASCII format.

GPM 地面验证二维视频谱仪（2DVD）HyMeX 数据集，系在地中海水循环实验（HyMeX）期间收集，旨在提供关于雨滴尺寸及降水滴尺寸分布的数据。2DVD 不仅测量了雨滴尺寸，还记录了每个雨滴的两侧视图光学图像。该仪器用于现场测量降水滴尺寸分布，记录了雨滴穿越其感应区域时的正交图像投影，并提供了单个雨滴的速度和形状。HyMeX 2DVD 数据于 2012 年 9 月 12 日至 2012 年 11 月 12 日在法国和意大利收集。数据格式为 ASCII。
