Evidence and effects of the sunrise enhancement of the equatorial vertical plasma drift in the F region ionosphere
(American Geophysical Union, 2016-05-13)
Recent studies based on the satellite observations demonstrated that the equatorial vertical plasma drift can also enhance near sunrise in a way similar to the prereversal enhancement. However, it is not clear whether the ...
Equatorial electrojet responses to intense solar flares under geomagnetic disturbance time electric fields
(American Geophysical Union, 2017-01-12)
Large enhancement in the equatorial electrojet (EEJ) current can occur due to sudden increase in the E layer density arising from solar flare associated ionizing radiations, as also from background electric fields modified ...
Observation of intensity of cosmic rays and daily magnetic shifts near meridian 70 degrees in the South America
(Elsevier, 2016)
In analysis of experiments carried during September 2008 using secondary cosmic ray detectors located in Chacaltaya (Bolivia) and Niteroi (Brazil), Augusto et al. (2010) showed an increase in the intensity of charged ...
Storm time dependence of equatorial disturbance dynamo zonal electric fields
(American Geophysical Union, 1997-11-01)
We use Jicamarca radar observations of F region vertical plasma drifts and auroral electrojet indices during 1968–1988 to study the characteristics and temporal evolution of equatorial disturbance dynamo zonal electric ...
Barbados: public-private sector partnership
(ECLAC, 2010-03)
Many successful countries, especially latecomers, in terms of export diversification and enhancement have not relied entirely on spontaneous market forces. Rather they have developed public-private alliances to build ...
Equatorial zonal plasma drifts measured by the C/NOFS satellite during the 2008–2011 solar minimum
(American Geophysical Union, 2013-06-26)
We use the measurements by the Vector Electric Field Investigation (VEFI) on board the Communication/Navigation Outage Forecasting System (C/NOFS) satellite to study the local time and seasonal‐ and longitudinal‐dependent ...
Abnormally large magnetospheric electric field on 9 November 2004 and its effect on equatorial ionosphere around the world
(Springer Verlag, 2012-10)
There was a solar event around 1850 UT on 9th November 2004, associated with an abnormally large solar wind flow pressure and large southward interplanetary magnetic field, causing an abnormally large prompt penetration ...
Diurnal evolution of the F region electron density local time gradient at low and middle latitudes resolved by the Swarm constellation
(American Geophysical Union, 2016-09-02)
In this study we have provided new insights into the local time gradient of F region electron density (ΔNe) derived from the lower pair of Swarm satellites flying side by side. Our result shows that the electron density ...
Grazing diverse combinations of tanniferous and nontanniferous legumes: implications for foraging behavior, performance, and hair cortisol in beef cattle
(American Society of Animal Science, 2021-10-17)
A diversity of forages with different types and concentrations of nutrients and plant secondary compounds may lead to complementary relationships that enhance cattle performance and welfare. We determined whether grazing ...
