abstract = "Ionospheric irregularities can affect trans-ionospheric radio
signals from Global Navigation Satellite Systems (GNSS), High
Frequency (HF) communication, and the satellites control system.
One way to understand and predict such irregularities is to
compare the amplitude scintillation index during solar maximum and
minimum in different regions. The aim of this study is to performs
S4 comparison in the Equatorial Ionospheric Anomaly (EIA) and
South Atlantic Magnetic Anomaly (SAMA) regions. The results show
important increases in the spring and summer of southern
hemisphere of these regions, especially during the solar maximum.
This understanding intends to contribute in the forecast of radio
signals obstruction of receivers located on the Earths surface in
order to improve communication and navigation accuracy.",
