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:

该项目的目的是调查全球定位系统接收器观测到的相位和振幅振幅振荡的时空演变情况，并以加拿大高北极电离层网络扩大设施的加拿大高级数字电离层探测仪接收器的观测结果作为对这项研究的补充。将把对全球定位系统闪烁观测的定量分析与电磁波通过模型湍流电离层向前传播的数值模拟进行比较。计算结果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答案：
