Publikováno v: Earth, Planets and Space. 75

The occurrence of plasma irregularities and ionospheric scintillation over the Caribbean region have been reported in previous studies, but a better understanding of the source and conditions leading to these events is still needed. In December 2021,

Ionospheric Variability over the Brazilian Equatorial Region during the Minima Solar Cycles 1996 and 2009: Comparison between Observational Data and the IRI Model

Autor: Ângela M. Santos, Christiano G. M. Brum, Inez S. Batista, José H. A. Sobral, Mangalathayil A. Abdu, Jonas R. Souza, Rodolfo de Jesus, Periasamy K. Manoharan, Pedrina Terra

Publikováno v: Atmosphere; Volume 14; Issue 1; Pages: 87

The behavior of the Brazilian equatorial ionosphere during the solar minimum periods, 1996 and 2009, which cover the solar cycles 22/23 and 23/24, respectively, is investigated. For this, the F2 layer critical frequency (foF2) and peak height (hmF2)

Rotational temperatures retrival from the Arecibo Observatory Ebert-Fastie spectrometer and their inter-comparison with Lidar and SABER measurements

Autor: Sukanta Sau, Pedrina Terra, Christiano G. M. Brum, Fabio Vargas, Robert B. Kerr, Jens Lautenbach

Key Points: 1) Good inter-comparison is obtained between Arecibo observatory spectrometer and Lidar temperatures and results are similar to previous studies. 2) The temperature comparison improves considerably when time varying weighting functions ar
