Radar Studies of the Low Latitude Ionosphere

PI将继续使用非相干雷达测量、全球对流以及热层和电离层数值模型对低纬度电离层进行研究。 这些研究的目标是对控制低纬度和赤道电离层的电动过程有基本的了解，并开发平静时间全球气候和风暴时间预测分析电离层电场模型。 PI将利用从希卡马卡和阿雷西博获得的大量雷达测量数据以及极光磁场数据来模拟低电离层和赤道电离层对磁层扰动的响应。 费耶尔将采用新的数据分析程序，研究与高纬度对流增强和亚暴有关的低纬度电动力学效应，以及风暴时风驱动的电场，然后是高纬度电离层的大能量沉积。 在阿雷西博和希卡马卡进行的高分辨率实验将使用更多的数据采集和分析程序，以研究从较低高度进入低纬度电离层的能量和动量的耦合。 最后，参与者将利用长期观测活动研究中层大气和中间层过程对平静时间赤道等离子体漂移变异性的影响。

The PI will continue his studies of the low latitude ionosphere using incoherent radar measurements, global convection, and thermospheric and ionospheric numerical models. These studies' objectives are basic understanding of electrodynamic processes controlling the low latitude and equatorial ionospheres, and developing quiet time global climatological and storm time predictive analytical ionospheric electric field models. The PIs will use extensive radar measurements from Jicamarca and Arecibo, and auroral magnetic field data to model the response of the low and equatorial ionosphere-to-magnetosphere disturbances. Fejer will apply new data analysis procedures to examine the low latitude electrodynamic effects associated with high latitude convection enhancements and substorms, also with storm time wind driven electric fields, followed by large energy depositions into the high latitude ionosphere. High resolution experiments carried out at Arecibo and Jicamarca will use significantly more data taking and analysis procedures to study coupling of energy and momentum from lower altitudes into the low latitude ionosphere. Finally, the PIs will study effects of middle atmospheric and mesospheric processes on the variability of quiet-time equatorial plasma drifts using long period observational campaigns.***
