GPM GROUND VALIDATION ENVIRONMENT CANADA (EC) RADIOSONDE GCPEX V1

The GPM Ground Validation Environment Canada (EC) Radiosonde GCPEx dataset provides measurements of pressure, temperature, humidity, and winds collected by Vaisala RS92 Radiosondes during the GPM Cold-season Precipitation Experiment (GCPEx) at the CARE site in Ontario, Canada, January 17, 2012 through February 29, 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. These data sets were 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.

加拿大环境部（EC）为GPM地面验证项目提供的GPM冷季降水实验（GCPEx）Vaisala RS92高空气球数据集，记录了在加拿大安大略省CARE站点于2012年1月17日至2012年2月29日期间，通过Vaisala RS92高空气球收集到的气压、温度、湿度和风速等气象参数。GCPEx旨在解决GPM降雪检索算法的不足，通过收集微物理特性、相关遥感观测数据以及协调的降雪模型模拟数据来实现。此数据集的收集旨在助力实现GCPEx的总体目标，即表征多频段主动和被动微波传感器在检测和估计降雪过程中的能力。
