抽象。利用美国国防气象卫星计划（DMSP）探测器的电子温度（Te）、格拉姆斯敦电离层探测站的F2层临界频率（foF2）和F2层峰值高度（hmF2）观测资料，研究了2005年10月3日日食期间共轭半球电离层的行为。和来自全球定位系统（GPS）站SUTH的总电子含量（TEC）。观测结果表明，当食发生在北方半球时，与参考值相比，Te降低，foF2和TEC升高，hmF2升高。我们还使用中低纬度电离层模型模拟了这次日食期间的电离层行为。模拟结果与观测结果吻合较好。由于日食效应，从日食区到共轭区沿着磁场线行进的光电子要少得多，导致共轭半球中的光电子加热减少，这导致电子温度下降和该区域中的后续扰动。
Abstract. We investigate the ionospheric behavior in conjugate hemispheres during the 3 October 2005 solar eclipse, on the basis of observations of electron temperature (Te) from the Defense Meteorological Satellites Program (DMSP) spacecraft, F2 layer critical frequency (foF2) and F2 layer peak height (hmF2) at the Grahamstown ionosonde station, and total electron content (TEC) from the Global Positioning System (GPS) station SUTH. The observations show that when the eclipse occurred in the Northern Hemisphere, there was a decrease in Te, an increase in foF2 and TEC, and an uprising in hmF2 in its conjugate region compared with their reference values. We also simulated the ionosphere behavior during this eclipse using a mid- and low-latitude ionospheric model. The simulations agree well with the observations. Because of the eclipse effect, there are far fewer photoelectrons travelling along the magnetic field lines from the eclipse region to the conjugate region, resulting in reduced photoelectron heating in the conjugate hemisphere which causes a drop in electron temperature and subsequent disturbances in the region.
