GPM GROUND VALIDATION ACHIEVE W-BAND CLOUD RADAR IPHEX V1

The GPM Ground Validation ACHIEVE W-band Cloud Radar IPHEx dataset consists of cloud and light precipitation radar observations gathered during the Global Precipitation Measurement (GPM) mission Ground Validation Integrated Precipitation and Hydrology Experiment (IPHEx) Intensive Observing Period (IOP) in North Carolina from May 1 through June 15, 2014. The goal of IPHEx was to evaluate the accuracy of satellite precipitation measurements and use the collected data for hydrology models in the region. The dataset includes data from the ProSensing 95 GHz W-band cloud radar, which is part of the NASA Goddard Space Flight Center (GSFC) Aerosol, Cloud, Humidity, Interactions Exploring and Validating Enterprise (ACHIEVE) ground-based mobile laboratory. The W-band cloud radar is a scanning 95 GHz dual-polarization (horizontal transmission and co- and cross-polar receiving) Doppler radar used for observing liquid and ice clouds and light precipitation. The instrument measures co- and cross-polar reflectivity, radial velocity, Doppler spectrum width, and signal-to-noise ratio. Linear depolarization ratio was derived from the measured parameters. During the IPHEx campaign, the W-Band radar was used exclusively in vertical-pointing mode. The dataset files are available from May 9 through June 14, 2014 in netCDF-3 data format.

GPM 地面验证 ACHIEVE W 波段云雷达 IPHEx 数据集，由全球降水测量任务（GPM）地面验证综合降水与水文实验（IPHEx）密集观测期（IOP）在北卡罗来纳州从 2014 年 5 月 1 日至 6 月 15 日期间收集的云与轻微降水雷达观测数据组成。IPHEx 的目标在于评估卫星降水测量的准确性，并利用收集到的数据对区域内的水文模型进行应用。该数据集包含来自 ProSensing 95 GHz W 波段云雷达的数据，该雷达为美国宇航局戈达德太空飞行中心（NASA Goddard Space Flight Center, GSFC）的气溶胶、云、湿度、相互作用探索与验证企业（ACHIEVE）地面移动实验室的一部分。W 波段云雷达是一种用于观测液态和冰云以及轻微降水的扫描式 95 GHz 双极化（水平传输和共极与交叉极接收）多普勒雷达。该仪器测量共极与交叉极反射率、径向速度、多普勒频谱宽度和信噪比。线性去极化比由测量参数推导得出。在 IPHEx 调查期间，W 波段雷达仅在垂直指向模式下使用。数据集文件以 netCDF-3 数据格式从 2014 年 5 月 9 日至 6 月 14 日可用。
