Applying Machine Learning to Equatorial Plasma Bubble Now Casting on CubeSats [PDF]

Equatorial plasma bubbles are a space weather phenomenon that occur at low latitudes within the Earth’s ionosphere. These bubbles are regions of low-density plasma that form at the base of the ionosphere and expand upward through the peak and into the ...

Radio-tomographic images of postmidnight equatorial plasma depletions [PDF]

, 2014
For the first time, equatorial plasma depletions (EPDs) have been imaged in the longitude-altitude plane using radiotomography. High-resolution (~10 km) reconstructions of electron density were derived from total electron content (TEC) measurements ...

Can Numerical Simulations of Equatorial Plasma Bubble Plume Structures be Simplified for Operational and Practical Usage?

Navigation
We argue the merits of having a simplified method to simulate equatorial plasma bubble (EPB) plume structures for practical usage. The capability to realistically model EPB plume structures in simulations would be advantageous when assessing the severity

Observation of Equatorial Plasma Depletions at Southern Taiwan by 6300Å OI Airglow

, 2000
In this study, we use a fisheye lens (180o field of view) and Chare-Couple Device to take the all-sky 6300Å airglow images emitting from ionosphere.

The measured motions inside equatorial plasma bubbles [PDF]

, 1986
A preliminary study of the vertical and north-south horizontal ion motions in plasma bubbles in the near-equatorial ionosphere utilizing drift meter data from Atmosphere Explorer E is presented. High resolution data show that the vertical ion velocity in

Simulation of Equatorial Plasma Bubble Signatures in GNSS TEC

Remote Sensing
Equatorial plasma bubbles (EPBs) are ionospheric plasma depletions that can disrupt Global Navigation Satellite System (GNSS) signals and degrade positioning at equatorial and low latitudes.

The Effect of Plasma Releases on Equatorial Spread F—a Simulation Study

Frontiers in Astronomy and Space Sciences, 2019
A currently unfulfilled goal of active experimentalists is to control the occurrence of instabilities in the ionosphere such as Equatorial Spread F (ESF), which generates large-scale electron density depletions (plasma bubbles) in the night-time ...

Unexpected Field-Aligned Structure in Equatorial Plasma Bubbles

Equatorial plasma bubbles, commonly known as EPBs, are field-aligned ionospheric irregularities in the bottomside of the F-region equatorial ionosphere generated due to the RayleighTaylor instability.
