GPM Ground Validation KATX NEXRAD OLYMPEX V1

The GPM Ground Validation KATX NEXRAD OLYMPEX dataset contains data from selected NEXt Generation Weather RADar system (NEXRAD) instruments in operation during the Olympic Mountains Experiment (OLYMPEX) field campaign to help support the ground validation of the Global Precipitation Measurement (GPM). NEXRAD is a network of 160 stationary S-Band radars dispersed throughout the United States and select locations abroad. Datasets gathered from three NEXRAD stations, as listed below, extend from 22 September 2015 through 01 May 2016 as part of the GPM Ground Validation OLYMPEX data. This dataset 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KATX NEXRAD OLYMPEX数据集汇集了在奥林匹克山脉实验（OLYMPEX）野外考察期间，运行中的选定的下一代天气雷达系统（NEXRAD）仪器所收集的数据，旨在支持全球降水测量（GPM）的地面验证。NEXRAD是一个遍布美国及海外选定位置的160个固定S波段雷达网络。本数据集从以下三个NEXRAD站点收集的数据，时间跨度为2015年9月22日至2016年5月1日，作为GPM地面验证OLYMPEX数据的一部分。该数据集包含基于PNG格式的底反射率观测浏览图像。底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，该信息可以展示出给定大气单位体积中水粒子的数量和尺寸分布。
