GPM Ground Validation KCAE NEXRAD IPHEx V1

The GPM Ground Validation KCAE NEXRAD IPHEx datasets contain data from the KCAE NEXt Generation Weather RADar system (NEXRAD) instrument 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 KCAE NEXRAD IPHEx 数据集收录了在综合降水和水利实验（IPHEx）野外考察期间，KCAE NEXt Generation Weather RADar 系统 尽管（NEXRAD）仪器所采集的数据，旨在协助支持全球降水测量（GPM）的地面验证，并评估针对美国东南地区水利预测的定量降水估计（QPE）产品。NEXRAD 是一个遍布美国及选定海外地区的 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）格式存储的基本反射率观测图像。基本雷达反射率是指雷达在拦截目标（例如，雨滴）后返回的传输功率的度量，此类信息能够展示在特定大气体积单位中的水粒子数量及其尺寸分布。
