Low Latitude Plasma Blobs: A Review [PDF]

Journal of Astronomy and Space Sciences, 2016
In recent years, there has been renewed activity in the study of local plasma density enhancements in the low latitude F region ionosphere (low latitude plasma blobs).

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 ...

A system science perspective of the drivers of equatorial plasma bubbles

Frontiers in Astronomy and Space Sciences, 2023
The complex drivers of equatorial plasma bubbles and resulting scintillation requires a system science approach spanning the Magnetosphere-Ionosphere-Thermosphere-Mesosphere disciplines.

Microbubbles enhanced synthetic phorbol ester degradation by ozonolysis [PDF]

, 2014
A phorbol-12-myristate-13-acetate (TPA) is a synthetic analogue of phorbol ester (PE), a natural toxic compound of Euphorbiaceae plant. The oil extracted from plants of this family is useful source for primarily biofuel.

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

Geophysical 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.

Analysis of the seasonal variations of equatorial plasma bubble occurrence observed from Haleakala, Hawaii [PDF]

Annales Geophysicae, 2004
Over 300 nights of airglow and GPS scintillation data collected between January 2002 and August 2003 (a period near solar maximum) from the Haleakala Volcano, Hawaii are analyzed to obtain the seasonal trends for the occurrence of equatorial plasma ...

Effect of equatorial plasma bubbles on the thermosphere [PDF]

Journal of Geophysical Research: Space Physics, 2003
Equatorial plasma bubbles are common in the low‐latitude ionosphere at night, particularly at solar maximum. The bubbles form on the bottomside of the F‐layer as a result of the Rayleigh‐Taylor instability and then drift upwards and to the east. As the bubbles evolve, the entire north‐south extent of the plasma flux tubes in the bubbles becomes ...
