The intense plasma irregularities within the ionospheric sporadic E (Es) layers at 90–130 km
altitude have a significant impact on radio communications and navigation systems. As a …

A moon shadow of annular solar eclipse passed through East Asia in the afternoon on June
21, 2020, which was a good opportunity to study the rapid ionospheric response to the solar …

The ionospheric sporadic E (Es) layer has a significant impact on the global positioning
system (GPS)/global navigation satellite system (GNSS) signals. These influences on the …

There have been a number of papers reporting that the statistical occurrence rate of the
sporadic E (Es) layer depends not only on the local time and season but also on the …

The S4max data retrieved from the Constellation Observing System for the Meteorology,
Ionosphere, and Climate (COSMIC) radio occultation (RO) measurements during 2007 to …

Using 63 and 56 yr of continuous observations, we investigate the long‐term oscillations
and residual linear trends, respectively, in the E‐and F‐region ionosonde measured …

In the present work, we analyze the competition between tidal winds and electric fields in the
formation of blanketing sporadic E layers (Es b) over São Luís, Brazil (2° 31′ S, 44° 16 …

This work presents new results about simulations of blanketing sporadic E-layers, Es b,
using a modified version of a theoretical model for the E region (MIRE) for a Brazilian region …

Midlatitude ionosonde observations show that there is a sporadic E (Es) diurnal cycle that
starts in higher altitudes at sunrise. This property is labeled as the “Sporadic E sunrise …

This study analyzes strong sporadic E layer (Es) formation in Boa Vista (BV, 2.8° N, 60.7° W,
dip: 18°), a low‐latitude region in the Brazilian sector, which occurred far after the onset of a …
