GPM Ground Validation KLGX NEXRAD OLYMPEX V1

The GPM Ground Validation KLGX 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 KLGX NEXRAD OLYMPEX 数据集收录了在奥林匹克山脉实验（OLYMPEX）现场活动中，所选 NEXt 代气象雷达系统（NEXRAD）仪器运行期间收集的数据，旨在辅助全球降水测量（GPM）的地面验证。NEXRAD 是一个遍布美国及部分海外地区的 160 个固定 S 波段雷达网络。本数据集包含来自以下三个 NEXRAD 站点的数据集，时间跨度自 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测量，该信息可以展示出给定大气单位体积内水分子的数量和尺寸分布。
