Plasma Bubbles in the Ionosphere: BC/ISR at EPB-4

Equatorial plasma bubbles (EPBs), large plasma density depletions in the Earth’s ionosphere, are an important focus of BC/ISR’s ionospheric research. These bubbles can distort radio signals and severely disrupt satellite communications & GPS-based navigation. ISR scientists recently presented their work at the 4th International Workshop on Equatorial Plasma Bubbles held in Sao Paulo Brazil.  Rezy Pradipta gave a keynote on global coordination of EPB data analysis, Teddy Surco Espejo described low-cost instrumentation for better ionospheric monitoring, and Cesar Valladares discussed the statistics fromlong-term observations of several EPB-related phenomena.
