GPM Ground Validation KRTX NEXRAD OLYMPEX V1

The GPM Ground Validation KRTX 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 03 November 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 KRTX NEXRAD OLYMPEX 数据集收录了在奥林匹克山脉实验（OLYMPEX）野外考察期间，选定的下一代天气雷达系统（NEXRAD）仪器所采集的数据，旨在协助全球降水测量（GPM）的地面验证。NEXRAD 是一个由 160 部固定式 S 波段雷达组成的网络，遍布美国及部分海外地区。该数据集涵盖了以下三个 NEXRAD 站点收集的数据，时间跨度从 2015 年 11 月 3 日至 2016 年 5 月 1 日，作为 GPM 地面验证 OLYMPEX 数据的一部分。数据集中包含基于基础反射率的浏览图像，格式为便携式网络图形（PNG）。基础雷达反射率是指雷达在截获目标（例如雨滴）后返回的传输功率的衡量，该信息能够展示在特定体积的空气中水分子的数量和尺寸分布情况。
