GPM Ground Validation NASA W-band Aircraft Cloud Radar (WACR) C3VP

The GPM Ground Validation NASA W-band Airborne Cloud Radar (WACR) C3VP dataset consists of calibrated co- and cross-polarized radar reflectivity at 94 GHz during the Canadian CloudSat/CALIPSO Validation Project (C3VP) field campaign. The campaign took place in southern Canada in support of multiple science missions, including the NASA GPM mission, in order to improve the modeling and remote sensing of winter precipitation. The WACR is used for cloud sensing and microphysics. During C3VP, the WACR was deployed as a surface-based, zenith-pointing instrument in the Cloud Radar Trailer at the Centre for Atmospheric Research Experiments (CARE) facility in Ontario, Canada. The data include radar reflectivities in zenith-pointing orientation at the CARE facility. The dataset files are available in netCDF format from October 30, 2006 through March 2, 2007.

GPM 地面验证项目 NASA W波段机载云雷达（WACR）C3VP 数据集包括在加拿大云卫星/CALIPSO 验证项目（C3VP）野外考察期间，于 94 GHz 频段进行的校准共极化和交叉极化雷达反射率数据。该考察活动在加拿大南部进行，旨在支持包括 NASA GPM 任务在内的多项科学任务，以提升冬季降水的建模与遥感技术。WACR 主要应用于云探测和微物理研究。在 C3VP 项目期间，WACR 作为地面基、顶视向的仪器，被部署在位于加拿大安大略省大气研究实验中心（CARE）设施的云雷达拖车内。数据集包含在 CARE 设施顶视向的雷达反射率。数据文件以 netCDF 格式提供，时间范围自 2006 年 10 月 30 日至 2007 年 3 月 2 日。
