GPM GROUND VALIDATION ENVIRONMENT CANADA (EC) VISIBILITY SENSOR FD12P AND PRESENT WEATHER DETECTOR GCPEX V1

The GPM Ground Validation Environment Canada (EC) Visibility Sensor FD12P and Present Weather Detector GCPEx dataset contains data collected from January 15 through March 1, 2012 in Huronia, Canada for the GPM Cold-season Precipitation Experiment (GCPEx). This dataset was collected to aid in the achievement of the over arching goal of GCPEx which is to characterize the ability of multi-frequency active and passive microwave sensors to detect and estimate falling snow. The FD12P combines the functions of a forward scatter visibility meter and a present weather detector. It also measures the intensity and the amount of both liquid and solid precipitation.

GPM 地面验证环境加拿大（EC）可见度传感器 FD12P 以及当前天气探测器 GCPEx 数据集，收录了2012年1月15日至3月1日在加拿大 Huronia 地区为 GPM 冷季降水实验（GCPEx）所收集的数据。该数据集的收集旨在协助实现 GCPEx 的总体目标，即描述多频率主动和被动微波传感器在检测和估计下雪能力方面的性能。FD12P 结合了前向散射可见度计和当前天气探测器的功能，同时测量液态和固态降水的强度和数量。
