Evolution of equatorial ionospheric plasma bubbles and formation of broad plasma depletions measured by the C/NOFS satellite during deep solar minimum
(American Geophysical Union, 2011-03-08)
An unexpected feature revealed by the measurements of the Communication/Navigation Outage Forecasting System (C/NOFS) satellite is the presence of broad plasma depletions in the midnight–dawn sector during deep solar ...
Are plasma bubbles a prerequisite for the formation of broad plasma depletions in the equatorial F region?
(American Geophysical Union, 2013-06-24)
Formation of broad plasma depletions (BPDs) at night in the equatorial F region is understood in association with plasma bubbles. However, we report BPDs that do not show a connection with bubbles. The characteristics of ...
Broad plasma depletions detected in the bottomside of the equatorial F region: Simultaneous ROCSAT-1 and JULIA observations
(American Geophysical Union, 2014-07-09)
We investigated the association of broad plasma depletions (BPDs) with plasma bubbles and ionospheric uplift in the equatorial F region using the coincident satellite and radar observations over Jicamarca in Peru. BPDs ...
Tomographic imaging of ionospheric plasma bubbles based on GNSS and radio occultation measurements
(2018-10-01)
Total electron content measurements given by the global navigation satellite system (GNSS) have successfully presented results to capture the signatures of equatorial plasma bubbles. In contrast, the correct reproduction ...
First detection of the supersonic upward plasma flow structures in the early morning sector
(American Geophysical Union, 2015-11-04)
We present the first observations of the supersonic updrafting plasma drifts in the predawn sector. Two DMSP satellites quasi‐simultaneously detected two fast‐speed events: one of ~385 km spatial extension and with the ...
Tomographic imaging of equatorial plasma bubbles
(American Geophysical Union, 2006-08-04)
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 ...
Statistics of total electron content depletions observed over the South American continent for the year 2008
(American Geophysical Union, 2011-10-29)
This paper presents for the first time regional plots of total electron content (TEC) depletions derived from GPS observations over the South American continent with a coverage of over 45° longitude (i.e., 35°W to 80°W). ...
Equatorial plasma bubbles and L-band scintillations in Africa during solar minimum
(European Geosciences Union (EGU), 2012-04-16)
We report on the longitudinal, local time and seasonal occurrence of equatorial plasma bubbles (EPBs) and L band (GPS) scintillations over equatorial Africa. The measurements were made in 2010, as a first step toward ...
Rocket in situ observation of equatorial plasma irregularities in the region between E and F layers over Brazil
(European Geosciences Union, 2017-03-16)
A two-stage VS-30 Orion rocket was launched from the equatorial rocket launching station in Alcântara, Brazil, on 8 December 2012 soon after sunset (19:00LT), carrying a Langmuir probe operating alternately in swept and ...
