Collaborative Research: The Thermosphere-Ionosphere Coupling Using the Low-latitude Ionospheric Sensor Network (LISN) Distributed Observatory

该项目为低纬度电离层传感器网络（LISN）的持续运行和科学调查提供资金。LISN是一个由GPS接收器、磁力计和电离层探空仪组成的分布式阵列，用于测量南美洲低纬度地区的电离层参数。该网络位于同一个大陆，位于Jicamarca天文台的纬度带内，Jicamarca天文台拥有一套热层-电离层观测系统。LISN天文台实现的首要科学目标是了解复杂的日常变化和日落后几乎每天在南美洲低纬度电离层发生的极端干扰。这些事件对通信、导航和高精度指向系统构成了突出的自然危害。本提案中概述的项目将有助于了解发生在低纬度和中纬度的等离子体结构的开始，并影响通信和导航系统。选择利用LISN实时数据的空间天气预报企业可以使用LISN实时数据。LISN是一个国际合作项目，在南美国家培养新的技术专长和研究生水平的航空课程。

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.
