TL;DR: In this article, two airglow CCD imagers, located at Cariri (7.4° S, 36.5° W, geomag. 11° S) and near Brasilia (14.8°S, 47.6°W, geOMag. 10°S) were operated simultaneously and measured the equatorial ionospheric bubbles and their time evolution by monitoring the airglove OI 6300 intensity depletions.
Journal ArticleDOI
Equatorial ionosphere bottom‐type spread F observed by OI 630.0 nm airglow imaging
H. Takahashi,M. A. Abdu,Michael J. Taylor,Pierre-Dominique Pautet,E. R. de Paula,Esfhan alam Kherani,Amauri Fragoso de Medeiros,Cristiano Max Wrasse,I. S. Batista,J. H. A. Sobral,Delano Gobbi,Daniela C. S. Arruda,Igo Paulino,Sharon L. Vadas,D. C. Fritts +14 more
TL;DR: In this article, bottom-type spread F events were observed in the south American equatorial region by a VHF coherent radar and an ionosonde at Sao Luis (2.5°S, 44.3°W).
Journal ArticleDOI
Ionospheric zonal velocities at conjugate points over Brazil during the COPEX campaign: Experimental observations and theoretical validations

Kherani,Amauri Fragoso de Medeiros,Ricardo Buriti,H. Takahashi,Nelson Jorge Schuch,Clezio Marcos Denardini,C.J. Zamlutti,A. A. Pimenta,J.R. de Souza,F. Bertoni +19 more
TL;DR: In this article, the velocities of large-scale ionospheric plasma depletions over two conjugate stations inferred from OI 630 nm airglow all-sky images obtained during the Conjugate Point Equatorial Experiment (COPEX) campaign carried out in Brazil between October and November 2002 were analyzed.
Journal ArticleDOI
Theoretical and experimental zonal drift velocities of the ionospheric plasma bubbles over the Brazilian region
Daniela C. S. Arruda,J. H. A. Sobral,M. A. Abdu,Vivian M. Castilho,H. Takahashi,Amauri Fragoso de Medeiros,Ricardo Buriti +6 more
TL;DR: In this article, equatorial ionospheric plasma bubble zonal drift velocity observations and their comparison with model calculations were performed taking into account flux-tube integrated Pedersen conductivity and conductivity weighted neutral zonal winds.
Journal ArticleDOI
Equatorial ionospheric responses to high-intensity long-duration auroral electrojet activity (HILDCAA)
J. H. A. Sobral,M. A. Abdu,Walter D. Gonzalez,Alicia L. Clúa de Gonzalez,Bruce T. Tsurutani,Renato Ribeiro Lira da Silva,Isabela Galvão Barbosa,Daniela C. S. Arruda,Clezio Marcos Denardini,C.J. Zamlutti,Fernando L. Guarnieri +10 more
TL;DR: In this paper, the authors focused on observational results of such coupling processes based on data collected during the phenomenon defined as high-intensity long-duration continuous AE activity (HILDCAA) which occurs outside the main phase of geomagnetic storms.
