GPM Ground Validation High Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) OLYMPEX V1a

The GPM Ground Validation High-Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) OLYMPEX dataset consists of Doppler velocity and reflectivity profiles collected by the High-Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) onboard the NASA ER-2 high-altitude research aircraft during the Global Precipitation Measurement mission (GPM) Ground Validation Olympic Mountains Experiment (OLYMPEX). The OLYMPEX field campaign took place between November 2015 and January 2016, with additional ground sampling continuing through February 2016, on the Olympic Peninsula in the Pacific Northwest of the United States. The purpose of the campaign was to provide ground-validation data for the measurements taken by instrumentation aboard the GPM Core Observatory satellite. 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) to obtain profiles of wind and rain. These Level 1B HIWRAP data files are available from November 10 through December 12, 2015 in netCDF-3 format.

GPM地面验证高空成像风和雨机载剖面仪（HIWRAP）OLYMPEX数据集由NASA ER-2高空研究飞机上的高空成像风和雨机载剖面仪（HIWRAP）收集的多普勒速度和反射率剖面组成，该数据集是在全球降水测量任务（GPM）地面验证奥林匹克山脉实验（OLYMPEX）期间收集的。OLYMPEX实地考察于2015年11月至2016年1月间进行，并在2016年2月继续进行地面采样，考察地点位于美国太平洋西北部的奥林匹克半岛。此次考察的目的是为GPM核心观测卫星上的仪器所进行的测量提供地面验证数据。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）以及两种不同的入射角（30度和40度）的锥形扫描模式测量，以获取风和雨的剖面。这些一级B HIWRAP数据文件以netCDF-3格式从2015年11月10日至12月12日可用。
