GPM Ground Validation KHTX NEXRAD IPHEx V1

The GPM Ground Validation KHTX NEXRAD IPHEx datasets contain data from the KHTX 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 16, 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KHTX NEXRAD IPHEx数据集包含在综合降水与水文实验（IPHEx）现场活动中，由KHTX下一代天气雷达系统（NEXRAD）仪器采集的数据，旨在支持全球降水测量（GPM）的地面验证，并评估美国东南地区水文预报中的定量降水估计（QPE）产品。NEXRAD是美国及其海外选定地点部署的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16日的时间段，作为GPM地面验证IPHEx数据集的一部分。NEXRAD数据集包含以便携式网络图形（PNG）格式浏览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，此类信息可以描绘出给定大气单位体积内水分子的数量和尺寸分布。
