1. 学术报告：Challenges in the upper atmosphere simulation 时间：2016年7月8日 地点：行政科研楼1412室 报告人：邓悦教授 单位：University of Texas Arlington, TX USA 摘要：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.
