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

The GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) GCPEX dataset was collected by the Two-Dimensional Video Disdrometer (2DVD) data, which was collected during the GPM Cold-season Precipitation Experiment (GCPEx) held in Ontario, Canada. GCPeX occurred in Ontario, Canada during the winter season of 2011-2012. GCPEx addressed shortcomings in the GPM snowfall retrieval algorithm by collecting microphysical properties, associated remote sensing observations, and coordinated model simulations of precipitating snow.Collected from six sites, the data contains daily ascii files with information on individual snowflakes and hydrometeors, and binary files preprocessed from raw camera data. Overall data dates range from 27 October 2011 through 27 February 2012 depending on the specific site.

GPM 地面验证二维视频降雪量计（2DVD）GCPEX 数据集由二维视频降雪量计（2DVD）数据收集而成，该数据是在加拿大安大略省举办的 GPM 冷季降水实验（GCPEx）期间采集的。GCPEx 实验于 2011-2012 年冬季在加拿大安大略省举行，旨在解决 GPM 雪量检索算法的不足，通过收集微物理特性、相关遥感观测数据以及协调的降水雪模型模拟来实现。数据集由六个站点收集而来，包含有关单个雪花和气溶胶的每日 ASCII 文件以及从原始相机数据中预处理得到的二进制文件。整体数据时间跨度从 2011 年 10 月 27 日至 2012 年 2 月 27 日，具体日期依据不同站点而定。
