This project funds continued operations and science investigations associated with the Low-Latitude Ionospheric Sensor Network (LISN). LISN is a distributed array of GPS receivers, magnetometers and ionosondes, that measure ionospheric parameters in the low-latitude South American sector. The network is on the same continent and within the latitude belt of the Jicamarca observatory, that hosts a suite of thermosphere-ionosphere observing systems. The overarching science goal enabled by the LISN observatory is to understand the complex day-to-day variability and the extreme disturbances that occur in the South American low-latitude ionosphere nearly every day after sunset. These occurrences pose a prominent natural hazard to communication, navigation and high precision pointing systems. The projects outlined in this proposal will help to understand the onset of plasma structuring that takes place at low and mid latitudes and that affect communication and navigation systems. LISN real-time data are available to space weather forecasting enterprises that elect to avail themselves of it. LISN is an international collaboration that nurtures new technological expertise and graduate-level aeronomy courses in South American countries.

该项目资助与低纬度电离层传感器网络（LISN）相关的持续运营和科学研究。 LISN 是一个由 GPS 接收器、磁力计和电离探空仪组成的分布式阵列，用于测量南美低纬度地区的电离层参数。该网络位于同一大陆，位于吉卡马卡天文台的纬度带内，该天文台拥有一套热层-电离层观测系统。 LISN 天文台的首要科学目标是了解南美低纬度电离层几乎每天日落后发生的复杂的日常变化和极端扰动。这些事件对通信、导航和高精度指向系统构成了显着的自然危害。该提案中概述的项目将有助于了解发生在低纬度和中纬度地区并影响通信和导航系统的等离子体结构的开始。 LISN 实时数据可供选择利用该数据的空间天气预报企业使用。 LISN 是一项国际合作项目，致力于在南美国家培养新技术专业知识和研究生水平的航空学课程。
