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

The GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) NSSTC dataset was collected by the Two-Dimensional Video Disdrometer (2DVD), which uses two high speed line scan cameras which provide continuous measurements of size distribution, shape and fall velocities of all precipitation particles and types. This 2DVD is the third generation 2D video disdrometer designed by Joanneum Research of Graz, Austria. This dataset provides rainfall data for the Global Precipitation Measurement (GPM) Mission Ground Validation Experiment collected at the National Space Science Technology Center (NSSTC) in Hunstville, AL. There may be occasional gaps in the data when the instrument is not resident at the NSSTC and is sent to participate in field campaigns.

GPM 地面验证二维视频降水电导计（2DVD）数据集由二维视频降水电导计（2DVD）收集而成，该设备配备了两台高速线扫描相机，能够连续测量所有降水粒子的尺寸分布、形状及下降速度。此2DVD为奥地利格拉茨的 Joanneum Research 设计的第三代二维视频降水电导计。本数据集提供了全球降水测量（GPM）任务地面验证实验在阿拉巴马州亨茨维尔的美国国家空间科学技术中心（NSSTC）收集的降雨数据。当仪器不在NSSTC且被派往参与野外考察时，数据中可能出现间歇性空缺。
