GPM Ground Validation KGSP NEXRAD IPHEx V1

The GPM Ground Validation KGSP NEXRAD IPHEx dataset contain data from the KGSP NEXt Generation Weather RADar system (NEXRAD) instruments in operation during the Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign to help support the ground validation of the Global Precipitation Measurement (GPM) and evaluate Quantitative Precipitation Estimation (QPE) products for hydrologic forecasting in the southeast region of the United States. NEXRAD is a network of 160 stationary S-Band radars dispersed throughout the United States and select locations abroad. These images extend from May 1, 2014 through June 12, 2014 as part of the GPM Ground Validation IPHEx datasets. The NEXRAD datasets contain browse images of base reflectivity observations in the Portable Network Graphic (PNG) format. Base radar reflectivity is the measure of transmitted power returned to the radar after intercepting a target, for example, rain droplets. This information can illustrate the amount and size distribution of water particles in a given unit volume of atmosphere.

GPM 地面验证 KGSP NEXRAD IPHEx 数据集包含了在综合降水和水利实验（IPHEx）野外实验期间，KGSP NEXt 代气象雷达系统（NEXRAD）仪器运行期间的数据。该数据集旨在支持全球降水测量（GPM）的地面验证，并评估美国东南部地区的水文预报的定量降水估计（QPE）产品。NEXRAD 是一个遍布美国及选定海外地点的 160 个固定 S 波段雷达网络。这些图像涵盖了从 2014 年 5 月 1 日至 2014 年 6 月 12 日的数据，作为 GPM 地面验证 IPHEx 数据集的一部分。NEXRAD 数据集包含了以便携式网络图形（PNG）格式存储的基础反射率观测浏览图像。基础雷达反射率是测量在拦截目标（例如，雨滴）后返回雷达的传输功率，该信息可以展示大气单位体积内水粒子的数量和尺寸分布。
