CEDAR: Studies of the Topside Ionosphere Using Multiple Radar and Satellite Data Sets

ATM9813853abs 研究人员将利用两个不相干散射雷达和国防气象卫星计划（DMSP）的两颗卫星的观测结果来研究上部电离层动力学、成分和温度。 结合两个来源的数据的能力提供了识别和量化 F 区中性风和等离子体漂移对上部电离层成分、温度和速度的影响的机会。 这些数据将借助一个模型来解释，该模型计算电离层成分、其温度和沿磁场线的速度的分布。 F 区域中的风调节电离层的位置和密度，进而影响等离子体分压的分布，从而产生场对准的离子流。 由于磁通量体积的变化，离子流传输热量并在顶部电离层中产生绝热加热和冷却。 目的是建立 F 区动力学与上部电离层成分和温度之间观测到的关系

ATM9813853absThe investigators will study topside ionospheric dynamics, composition, and temperature using observations from two incoherent scatter radars and two satellites from the Defense Meteorological Satellite Program (DMSP). The ability to combine date from the two sources provides the opportunity to identify and quantify the influences of F-region neutral winds, and plasma drifts on the topside ionosphere composition, temperature, and velocity. The data will be interpreted with the aid of a model that calculates the distributions of ionospheric constituents, their temperatures, and velocities along magnetic field lines. Winds in the F region modulate the location and density of the ionization layer, which in turn affects the distribution of plasma partial pressures resulting in field-aligned ion flows. The ion flows transport heat and produce adiabatic heating and cooling in the topside ionosphere due to the changing magnetic flux volume. The objective is to establish the observed relationships between F-region dynamics and topside ionospheric composition and temperature
