摘要

本文研究了大气在不同时空尺度上的物理变化。甚低频(VLF)无线电信号振幅的时间演变是表征大气季节变化的一种手段。基于微波的GNSS和合成孔径雷达(SAR)干涉测量技术被用作表征太阳x射线耀斑引起的大气物理性质异常的手段。

Studying the temporal variations of atmosphere physical properties at different spatial and temporal scales by VLF radio signals and space geodesy techniques

In this work we study the physical variations of atmosphere at different spatial and temporal scales. The temporal evolution of the amplitude of Very Low Frequency (VLF) radio signals is used as a means to characterize the seasonal variations of atmosphere. The microwave-based GNSS and Synthetic Aperture radar (SAR) interferometry techniques are used as a means to characterize anomalies in the physical properties of atmosphere due to solar X-ray flares.
