L-band scintillations and calibrated total electron content gradients over Brazil during the last solar maximum
(Edp Sciences S A, 2015-12-08)
This work presents a contribution to the understanding of the ionospheric triggering of L-band scintillation in the region over Sao Paulo state in Brazil, under high solar activity. In particular, a climatological analysis ...
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 ...
Ionospheric tomography using GNSS: multiplicative algebraic reconstruction technique applied to the area of Brazil
(2016-10-01)
Experimental analysis was performed using multiplicative algebraic reconstruction technique (MART) to map the ionosphere over Brazil. Code and phase observations from the global navigation satellite system (GNSS) together ...
NeQuick 2 total electron content predictions for middle latitudes of North American region during a deep solar minimum
(Elsevier, 2017-02)
The performance of NeQuick 2 model in computing the vertical total electron content (VTEC) over a wide region placed at middle latitudes of North America during the deep solar minimum that occurred in 2008 has been checked. ...
Ionospheric TEC Weather Map Over South America
(Amer Geophysical Union, 2016-11-01)
Ionospheric weather maps using the total electron content (TEC) monitored by ground-based Global Navigation Satellite Systems (GNSS) receivers over South American continent, TECMAP, have been operationally produced by ...
Localized increment and decrement in the total electron content of the ionosphere as a response to the April 20, 2018, geomagnetic storm
(Hindawi Limited, 2018)
A moderate geomagnetic storm occurred on April 20, 2018. Using vertical total electron content (VTEC) maps provided by the Center for Orbit Determination in Europe, ionospheric responses to the geomagnetic storm could be ...
