Atmospheric dispersion comparative study between a typical and a disturbed PBL using a doppler lidar
(Instituto de F??sica - USP, 2021)
Atmospheric electric field variations and lower ionosphere disturbance during the total solar eclipse of 2010 July 11
(Elsevier, 2016-11)
In this paper, we study the variations of atmospheric electric field during the total solar eclipse (TSE) of July 11, 2010, at Complejo Astronómico El Leoncito (CASLEO). These variations observed with two identical sensors ...
Unexpected connections between the stratosphere and ionosphere
(American Geophysical Union, 2010-05)
The coupling of the ionosphere to processes from below remains an elusive and difficult problem, as rapidly changing external drivers from above mask variations related to lower atmospheric sources. Here we use superposition ...

Equatorial electrojet 3-M irregularity dynamics during magnetic disturbances over Brazil: results from the new VHF radar at São Luı́s
(Elsevier, 2003-10)
Data collected during the first two observational campaigns, conducted in August 1998 and December 1999, using the new coherent back-scatter radar, developed at INPE, that became operational at the magnetic equatorial site ...
Theoretical effects of geomagnetic activity on low-latitude ionospheric electric fields
(American Geophysical Union, 2005-05-27)
The influence of geomagnetic activity on middle‐ and low‐latitude thermospheric winds and ionospheric electric fields is investigated using model results from the National Center for Atmospheric Research Thermosphere‐Ion ...
Early morning enhancement in ionospheric electron density
(Elsevier, 2012-01)
This study reports on ionospheric disturbances that occurred in the early morning hours in the South American–Atlantic sector during a few intense/super storm events. The events were observed at latitudes close to the ...
