GPM GROUND VALIDATION HIGH ALTITUDE IMAGING WIND AND RAIN AIRBORNE PROFILER (HIWRAP) IPHEX V1

The GPM Ground Validation High-Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) IPHEx dataset was collected during the Global Precipitation Measurement (GPM) Ground Validation Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign in North Carolina. 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 NASA ER-2 aircraft flew during the IPHEx field campaign to aid in GPM validation. The science instruments, including the HIWRAP, onboard the aircraft acted as a proxy for GPM satellite instruments. HIWRAP is a Doppler radar that combines conical scan mode measurements at two different frequency bands (Ka- and Ku-band) and two different incidence angles (30 and 40 degrees). Twenty-one ER-2 flights occurred from May 1, 2014 through June 14, 2014. The HIWRAP dataset includes netCDF-4 files containing radar reflectivity and Doppler velocity profiles along with aircraft altitude and other navigation information.

GPM 地面验证高空成像风速和降雨机载剖面仪（HIWRAP）IPHEx 数据集是在北卡罗来纳州进行的全球降水测量（GPM）地面验证综合降水和水利实验（IPHEx）现场活动中收集的。IPHEx 的目标在于评估卫星降水测量的准确性，并利用所收集的数据对区域内的水利模型进行应用。在 IPHEx 现场活动中，NASA ER-2 飞机执行任务以辅助 GPM 的验证。机载的科学仪器，包括 HIWRAP，作为 GPM 卫星仪器的代理。HIWRAP 是一种多普勒雷达，它结合了两个不同频率波段（Ka 波段和 Ku 波段）和两种不同的入射角度（30 度和 40 度）的锥形扫描模式测量。从 2014 年 5 月 1 日至 2014 年 6 月 14 日，共进行了 21 次ER-2 飞行。HIWRAP 数据集包含 netCDF-4 文件，其中包含雷达反射率和多普勒速度剖面，以及飞机高度和其他导航信息。
