报告人简介:

熊超,2007毕业于武汉大学电子信息学院,获工学学士学位;随后在武汉大学空间物理专业攻读博士学位。读博期间获德国DAAD奖学金和中国国家留学基金委资助,前往德国地学研究中心(GFZ)进行为期两年的访问学习,后与2012年6月获理学博士学位。博士毕业之后,获德国洪堡基金资助,继续在GFZ进行为期两年的博士后研究,之后一直在GFZ从事研究工作。研究内容主要涉及电离层物理,电离层-热层耦合,电离层/热层建模,以及电离层不规则体及其对导航信号的影响等。在博士后工作期间,参与多项德国科学基金委(DFG)以及欧空局(ESA)项目,取得创新成果。近年来在Geophysical Research Letter, Journal of Geophysical Research, Space weather, Annales Geophysicae等国际期刊上发表SCI论文40余篇 (第一作者20篇),先后获得“COSPAR杰出青年科学家论文奖(2012年)”和“EGU杰出青年科学家奖(2019年)”。

报告题目:Ionospheric Plasma Irregularities observed by the Low Earth Orbiting (LEO) satellites

报告内容简介

The ionosphere is the ionized part of Earth’s upper atmosphere, which is usually characterized by irregularities and fluctuations in plasma density. The ionospheric irregularities can influence the propagation of trans-ionospheric radio waves and are thus of importance for any operations that rely on precise positioning with Global Navigation Satellite Systems (GNSS). Therefore, understanding the ionospheric plasma irregularities is of both scientific and practical interest. In this report, we will summarize the plasma irregularities related studies by using measurements from low Earth orbiting (LEO) satellites, like CHAMP, GRACE, GOCE, and Swarm. In addition, the influence of plasma irregularities on the GNSS signal, especially for the receivers onboard LEO satellites have been also discussed.
