Collaborative Research: Coordinated Imaging and Scintillation Study of the Conjugate Nature of Equatorial Plasma Irregularities

点击翻译按钮获取中文摘要

The propagation of F-region equatorial irregularities along a common magnetic flux tube or along nearly common flux tubes is investigated using instruments deployed at Neiva, Columbia and at Cerro Tololo, Chile. The instruments deployed are all-sky imaging systems using 777.4 nm, 620.0 nm, and 557.7 nm narrow-band filters, and 50-Hz high sampling rate "ScintMon" GPS receivers. These instruments are complemented by the Jicamarca Peru ISR, other GPS receivers in South America, and C/NOFS satellite measurements to determine how local irregularity and scintillation data can be reconciled with physics of plasma transport along an entire magnetic flux tube.
