We bid farewell to Xiaohan Yin, who graduated from our research group in Summer 2023. During her time with us, she made significant contributions to our research on ionospheric remote sensing.

Research Highlights

Her key achievement was demonstrating that the peak height of the F2 region (hmF$_2$) can be determined globally by measuring the intensity ratio of atomic oxygen 130.4 and 135.6 nm emissions in far-ultraviolet nightglow using nadir-viewing photometers on CubeSats. Through numerical simulations, she established that observations from ~400 km altitude enable hmF$_2$ retrieval with errors of only a few kilometers (up to ~20 km). Her pioneering work, published in Earth and Planetary Physics, has paved the way for global-scale monitoring of the nighttime ionosphere at mid to low latitudes.
欢送尹晓菡同学从我课题组毕业。在课题组期间，她在电离层遥感研究方面做出了重要贡献。她的主要成果是证明了可以通过 CubeSat 天底向光度计测量远紫外夜光中原子氧 130.4 和 135.6 nm 发射的强度比来全球范围内确定 F2 区峰值高度（hmF$_2$）。通过数值模拟，她证实了在约 400 公里高度的观测可以实现 hmF$_2$ 的反演，误差仅为几公里（最大约 20 公里）。她的开创性工作发表在 Earth and Planetary Physics 期刊上，为中低纬度夜间电离层的全球尺度监测开辟了新途径。
We wish her continued success in her future professional endeavors. 祝愿她在未来的职业道路上继续取得优异成绩。
