CEDAR Post-Doc: Plasma Irregularities in Peru

该奖项将支持Jorge Chau博士在秘鲁Jicamarca射电天文台的博士后研究。本研究分为两个部分：(1)赤道电喷流50 MHz雷达回波的东西对称性研究，(2)e区不规则性的经向变化研究。对于第一个任务，研究人员将研究与附近安第斯山脉有关的重力波能量的穿透是否可能在维持雷达回波中观察到的不对称性方面发挥作用。对于第二个任务，研究人员将使用Jicamarca雷达和位于秘鲁Piura的50 MHz风廓线雷达同时进行测量，Piura位于Jicamarca以北约1000公里处。研究人员将寻找Piura夜间回声的可能差异，这些差异与Jicamarca上电离层磁连接位置上是否存在扩散F有关。

This award will support the postdoctoral research of Dr. Jorge Chau at the Jicamarca Radio Observatory in Peru. The research has two parts: (1) the study of the east-west symmetry in 50 MHz radar echoes from the equatorial electrojet, and (2) the study of meridional variations in the E-region irregularities. For the first task, the investigators will examine whether or not the penetration of gravity wave energy associated with the nearby Andean Cordillera may play a role in sustaining the observed asymmetry in the radar echoes. For the second task, the investigators will use simultaneous measurements made with the Jicamarca radar and a 50 MHz wind profiler radar in Piura, Peru, about 1000 km north of Jicamarca. The researchers will look for possible differences in nighttime echoes in Piura related to the presence or absence of spread F over Jicamarca at magnetically connected locations in the ionosphere.
