Seasonal-longitudinal variability of equatorial plasma bubbles [PDF]
Annales Geophysicae, 2004 We compare seasonal and longitudinal distributions of more than 8300 equatorial plasma bubbles (EPBs) observed during a full solar cycle from 1989-2000 with predictions of two simple models.

Occurrence of Equatorial Plasma Bubbles during Intense Magnetic Storms [PDF]
International Journal of Geophysics, 2011 An important issue in low-latitude ionospheric space weather is how magnetic storms affect the generation of equatorial plasma bubbles. In this study, we present the measurements of the ion density and velocity in the evening equatorial ionosphere by the

Tomographic imaging of equatorial plasma bubbles
Geophysical Research Letters, 2006 Recently the Global Ultraviolet Imager (GUVI) on‐board the Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) satellite has detected far ultraviolet (FUV) images of plasma depletions in the low‐latitude and equatorial ionosphere. A model of GUVI observation geometry was developed to simulate radiance observations of a model ionosphere ...

Filamentary Alfvénic structures excited at the edges of equatorial plasma bubbles [PDF]
Annales Geophysicae, 2007 Recent observations performed by the French DEMETER satellite at altitudes of about 710 km suggest that the generation of equatorial plasma bubbles correlates with the presence of filamentary structures of field aligned currents carried by Alfvén ...

Gravity wave seeding of equatorial plasma bubbles [PDF]
Journal of Geophysical Research: Space Physics, 1997 Some examples from the Atmosphere Explorer E data showing plasma bubble development from wavy ion density structures in the bottomside F layer are described. The wavy structures mostly had east–west wavelengths of 150–800 km; in one example it was about 3000 km.

STUDY ON AUTOMATED DETECTION OF EQUATORIAL PLASMA BUBBLES EPB
International Journal of Advanced ResearchA processing application has been developed to detect and characterize localized plasma decreases: Equatorial plasma bubbles. The algorithm used is based on an automated search for negative STEC variations during a GPS satellite passage. First, an example of detection is shown.

Equatorial plasma bubble seeding by MSTIDs in the ionosphere [PDF]
Progress in Earth and Planetary Science, 2018 Occurrences of equatorial plasma bubbles (EPBs) and medium-scale traveling ionospheric disturbances (MSTIDs) were studied using GPS satellite data-based total electron content mapping, ionograms, and 630 nm all-sky airglow images observed over the South ...

Magnetic Field and Electron Density Scaling Properties in the Equatorial Plasma Bubbles
Remote Sensing, 2022 The ionospheric plasma density irregularities are known to play a role in the propagation of electromagnetic signals and to be one of the most important sources of disturbance for the Global Navigation Satellite System, being responsible for degradation ...
