GPM GROUND VALIDATION ENVIRONMENT CANADA (EC) VAISALA CEILOMETER GCPEX V1

The GPM Ground Validation Environment Canada (EC) VAISALA Ceilometer GCPEx dataset was collected during the GPM Cold-season Precipitation Experiment (GCPEx) in Huronia, Canada from January 15, 2012 through March 1, 2012. The GPM Cold-season Precipitation Experiment (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. The CT25K ceilometer uses pulsed diode laser LIDAR technology to derive backscatter profiles, cloud heights and vertical visibilities. It is also able to detect 3 cloud layers simultaneously.

加拿大环境部（EC）的GPM地面验证项目收集了GPM冷季降水实验（GCPEx）期间在加拿大Huronia地区从2012年1月15日至2012年3月1日所获取的VAISALA ceilometer数据集。GCPEx实验于2011-2012年冬季在加拿大安大略省进行，旨在通过收集微物理特性、相关遥感观测数据以及降水雪的协调模型模拟，解决GPM降雪检测算法的不足。CT25K ceilometer采用脉冲二极管激光LIDAR技术，以推导出后向散射剖面、云高和垂直能见度。此外，该设备还能够同时检测到3层云。
