Ionospheric Turbulence, Scintillations and Space Weather Forecast

该项目的目的是调查全球定位系统(全球定位系统)接收器观测到的相位和幅度闪烁的空间和时间演变，并与扩大的加拿大北极高电离层网络设施的加拿大高级数字电离层探空仪接收器的观测结果相补充。对GPS闪烁观测的定量分析将与电磁波通过模型湍流电离层的前向传播的数值模拟进行比较。这些计算将用于深入了解极光和极地电离层区域内发生并导致闪烁现象的潜在机制。数据分析和与模拟的比较将有助于揭示以下基本问题的一些答案：

The objective of the project is to investigate the spatial and temporal evolution of phase and amplitude scintillations observed by the Global Positioning System (GPS) receivers, and complement the study with observations by the Canadian Advanced Digital Ionosonde (CADI) receivers of the Expanded Canadian High Arctic Ionospheric Network (ECHAIN) facility. The quantitative analysis of the GPS scintillation observations will be compared to numerical simulations of forward propagation of electromagnetic waves through a model turbulent ionospheric layer. The computations will be used to gain insight about potential mechanisms occurring within the auroral and polar ionospheric regions and causing the scintillation phenomena. The data analysis and the comparison to simulations will help unveil some of the answers to the following fundamental questions:
