Occurrence climatology of equatorial plasma bubbles derived using FormoSat-3 ∕ COSMIC GPS radio occultation data [PDF]

open access: yes, 2021
The Global Positioning System – Radio Occultation (GPS-RO) observations from FormoSat-3 ∕ COSMIC are used to comprehend the global distribution of equatorial plasma bubbles which are characterized by depletion regions of plasma in the F region of the ...

Global modeling of equatorial plasma bubbles [PDF]

open access: yesGeophysical Research Letters, 2010
The NRL three‐dimensional ionospheric simulation code SAMI3 is used to model the onset and evolution of equatorial spread F (ESF). SAMI3 is a comprehensive ionosphere model that has been modified to self‐consistently solve for the global neutral wind driven dynamo electric field as well as the gravity driven electric field associated with plasma ...

Stepping Into an Equatorial Plasma Bubble With a Swarm Overfly

open access: yesSpace Weather, 2023
AbstractESA's Swarm constellation entered in a “overfly” configuration in the period between September and October 2021, when the longitudinal distance between the lower pair and the upper satellite was at its minimum since the launch of the spacecrafts.

Comparison of Low‐Latitude Ionospheric Scintillation Forecasting Techniques Using a Physics‐Based Model

open access: yesSpace Weather, 2021
The temporal change in height of a specific electron density can be used as a proxy for vertical plasma drift (PVPD) at the magnetic equator. The use of PVPDs as a predictor of low‐latitude ionospheric scintillation during the subsequent evening has ...

The measured motions inside equatorial plasma bubbles [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 1984
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 some bubbles increases approximately linearly with (No‐N)/N, where No is the background ion ...

Faith in a seed: on the origins of equatorial plasma bubbles [PDF]

open access: yesAnnales Geophysicae, 2014
Abstract. Our faith in the seeds of equatorial plasma irregularities holds that there will generally always be density perturbations sufficient to provide the seeds for irregularity development whenever the Rayleigh–Taylor instability is active. When the duration of the time of the Rayleigh–Taylor instability is short, however, the magnitude of the ...

Global Modeling of Equatorial Spread F with SAMI3/WACCM‐X

open access: yesGeophysical Research Letters, 2020
We report the first results of a global ionosphere/thermosphere simulation study that self‐consistently generates large‐scale equatorial spread F (ESF) plasma bubbles in the postsunset ionosphere.
