Convective ionospheric storms: a major space weather problem
(American Geophysical Union, 2006-02-07)
Some 50 years into the space age, technical societies are deeply committed to the utilization of space. For the military, space is the ultimate high ground from which a variety of surveillance, communications, and navigation ...
The Low-Latitude Ionosphere Sensor Network: Initial results
(American Geophysical Union, 2012-05-18)
The Low-Latitude Ionospheric Sensor Network (LISN) is a distributed observatory designed to nowcast the state and dynamics of the low-latitude ionosphere and to develop forecasts of the electric fields, densities, and ...
Stormtime dynamics of the global thermosphere and equatorial ionosphere
(European Geosciences Union, 2009-05-05)
During magnetic storms the development of equatorial plasma bubbles (EPBs) and distributions of thermospheric densities are strongly influenced by the histories of imposed magnetospheric electric (εM) fields. Periods of ...
Equatorial F-layer heights, evening prereversal electric field, and night E-layer density in the American sector: IRI validation with observations
(Elsevier, 2004)
The equatorial F-layer height variations resulting from the variabilities in the zonal electric fields and winds and associated variability in ionospheric dynamo strength are important factors in determining the distribution ...
Response of equatorial, low- and mid-latitude F-region in the American sector during the intense geomagnetic storm on 24–25 October 2011
(Elsevier, 2013-07)
In this paper, we present and discuss the response of the ionospheric F-region in the American sector during the intense geomagnetic storm which occurred on 24–25 October 2011. In this investigation ionospheric sounding ...
Spread F - an old equatorial aeronomy problem finally resolved?
(European Geosciences Union (EGU), 2009-05-04)
One of the oldest scientific topics in Equatorial Aeronomy is related to Spread-F. It includes all our efforts to understand the physical mechanisms responsible for the existence of ionospheric F-region irregularities, the ...
Abnormal evening vertical plasma drift and effects on ESF and EIA over Brazil-South Atlantic sector during the 30 October 2003 superstorm
(2008-07-01)
Equatorial F region vertical plasma drifts, spread F and anomaly responses, in the south American longitude sector during the superstorm of 30 October 2003, are analyzed using data from an array of instruments consisting ...
