报告题目:Challenges in the Upper Atmosphere Simulation

报告人:Prof. Yue Deng    University of Texas Arlington, TX USA

报告主题简介:
The ionosphere and thermosphere are two overlapping regions of the upper atmosphere that are tightly coupled. The ionosphere represents the plasma and the thermosphere represents the neutral constituents. Understanding of the ionosphere/thermosphere system under different magnetospheric conditions is important for space research and space weather applications. Currently, the biggest problems that the upper atmosphere community faces include the unknown physical processes in the meso- and small-scales and the imprecision of the energy input to the system. Global Ionosphere Thermosphere Model (GITM), the first self-consistent non-hydrostatic model in the upper atmosphere, was developed to better simulate the ionosphere and thermosphere coupling. Meanwhile, various data and models are utilized to investigate the variations of energy inputs (solar irradiance and geomagnetic energy) and distribution and their influences on the coupled thermosphere-ionosphere system.Upper atmosphere is also important to other planets including exo-planets.

报告人简介:
Yue Deng is Associate Professor in the Department of Physics at the University of Texas at Arlington, Texas USA. She received her BS and MS degrees at the Peking University in 1997 and 2001, respectively, and her PhD degree at the University of Michigan at Ann Arbor in 2006. She is the co-developer of the first global non-hydrostatic model in the upper atmosphere, Global Ionosphere Thermosphere Model (GITM). Her main research interest is the coupling between ionosphere and thermosphere under different geospace conditions. Dr. Deng was awarded the National Science Foundation (NSF) CAREER award and American Physical Society (APS) Robert S. Hyer Research Award. Her research is supported by NSF, NASA and Air Force Office for Scientific Research (AFOSR).
