GPM GROUND VALIDATION GCPEX SNOW MICROPHYSICS CASE STUDY V1

The GPM Ground Validation GCPEX Snow Microphysics Case Study characterizes the 3-D microphysical evolution and distribution of snow in context of the thermodynamic environment observed during the February 24th, 2012 event of the GPM Cold-season Precipitation Experiment (GCPEx). The GPM Cold-season Precipitation Experiment 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 snow. This case study includes data from the Airborne Second Generation Precipitation Radar (APR-2), Dual-frequency Dual-polarized Doppler Radar (D3R), Dual Polarization Radiometer and the NCAR Cloud Microphysics Particle Probes.

本案例研究对2012年2月24日GPM冷季降水实验（GCPEx）期间观测到的热力学环境下雪的3-D微物理演变和分布进行了特征描述。GPM冷季降水实验于2011-2012年冬季在加拿大安大略省举行。GCPEx旨在弥补GPM降雪检索算法的不足，通过收集微物理特性、相关遥感观测数据和雪的协调模型模拟来进行分析。本案例研究涵盖了空中第二代降水雷达（APR-2）、双频双极化多普勒雷达（D3R）、双极化辐射计以及美国国家大气研究中心（NCAR）云微物理粒子探测器的数据。
