GPM Ground Validation KRAX NEXRAD IPHEx V1

The GPM Ground Validation KRAX NEXRAD IPHEx dataset contain data from the KRAX 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 KRAX NEXRAD IPHEx 数据集包含在综合降水与水文学实验（IPHEx）现场活动中运行的 KRAX NEXt 代气象雷达系统（NEXRAD）仪器的数据，旨在协助支持全球降水测量（GPM）的地面验证，并评估美国东南地区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位置的 160 个固定 S 波段雷达网络。这些图像从 2014 年 5 月 1 日至 2014 年 6 月 12 日生成，作为 GPM 地面验证 IPHEx 数据集的一部分。NEXRAD 数据集包含基于反射率的观察浏览图像，这些图像以可移植网络图形（PNG）格式存储。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，该信息可以展示大气单位体积内水分子的数量和尺寸分布。
