Climatology characterization of equatorial plasma bubbles using GPS data

Journal of Space Weather and Space Climate, 2017
The climatology of equatorial plasma bubbles (EPBs) for the period 1998–2008 was studied using slant total electron content (sTEC) derived from global positioning system (GPS) data.

Multi-scale irregularities product for space weather applications utilizing high-resolution Swarm plasma density data

Journal of Space Weather and Space Climate
The Earth’s ionospheric dynamics are multi-scale in nature, and the small-scale phenomena have been difficult to measure by in-situ techniques because of low data resolution.

IncResUnet: A Model for Automatic Ionospheric Plasma Bubble Detection

Space: Science & Technology
Plasma bubbles are important ionospheric phenomena in the equatorial region that can cause scintillation interference in high-frequency communication. Traditional methods for detecting plasma bubbles rely on measuring the deviation of ion density over a ...

Periodic spacing between consecutive equatorial plasma bubbles

Geophysical Research Letters, 2010
We analyze three‐years of data collected by a field‐aligned airglow imaging system located at the Cerro Tololo Inter‐American Observatory near La Serena, Chile to determine the occurrence of equatorial plasma bubbles (EPBs). On 317 of the 552 predominately clear nights of observations, structure indicative of EPBs is present.
