Biography & lecture abstract
Xiong Hu was born in Hubei Province, China (1967). He studied space physics at Wuhan University and Wuhan Institute of Physics and Mathematics, from the Chinese Academy of Sciences (CAS), and obtained his PhD in 1995. He currently works at the National Space Science Center, CAS, where he became the director of the Laboratory for Near-Earth Space Environment Research. His main scientific interests are the middle and upper atmospheric science and its detection techniques, as well as its modeling. He has been involved in radio occultation experiments, as well as ground-based observations including the sodium Doppler lidar, all-sky imager, medium-frequency radar and meteor radar. Dr. Hu is science team member of the Yinghuo-1 Mars mission. He has authored about 70 articles. He likes various sports.
Lecture: Martian radio occultation experiments with the Yinghuo-1 mission
Two kinds of radio occultation experiments will be performed with the YH-1 Mars mission to derive the Mars ionosphere electron density profiles and the neutral atmospheric profiles of temperature, density and pressure. The first experiment will be done using the radio link between YH-1 and Phobos-Grunt with dual frequencies of 400/800 MHz, which will be very sensitive to the ionospheric measurements. The second experiment is the traditional occultation experiment carried out in many previous planetary missions before, which will use the radio downlink between the YH-1 satellite and the deep space station on the Earth with the single X-band frequency. The two types of radio occultation experiments, using very different ideas and techniques, will allow us to investigate further the martian ionosphere and neutral atmosphere, especially the night-side ionosphere. Their inversion principles and simulation results will be presented.
