Ionospheric irregularity reconstruction using multisource data fusion via deep learning [PDF]

Atmospheric Chemistry and Physics, 2023
Ionospheric sporadic E layers (Es) are intense plasma irregularities between 80 and 130 km in altitude and are generally unpredictable. Reconstructing the morphology of sporadic E layers is not only essential for understanding the nature of ionospheric ...

Equatorial Plasma Bubbles: A Review

Atmosphere, 2022
The equatorial plasma bubble (EPB) phenomenon is an important component of space weather as the ionospheric irregularities that develop within EPBs can have major detrimental effects on the operation of satellite-based communication and navigation ...

D region HF radar echoes associated with energetic particle precipitation and pulsating aurora [PDF]

, 2008
Milan et al. (2001) identified a class of narrow, slow-moving HF radar backscatter echoes which originate between altitudes of 80 and 100 km, the ionospheric D- and lower E-regions.

Daytime F-region irregularity triggered by rocket-induced ionospheric hole over low latitude

Progress in Earth and Planetary Science, 2018
Unexpected daytime F-region irregularities following the appearance of an ionospheric hole have been observed over low latitude. The irregularities developed initially above the F-region peak height (~ 360 km) with a thickness of about 30 km and an east ...

Climatology of GPS phase scintillation and HF radar backscatter for the high-latitude ionosphere under solar minimum conditions [PDF]

Annales Geophysicae, 2011
Maps of GPS phase scintillation at high latitudes have been constructed after the first two years of operation of the Canadian High Arctic Ionospheric Network (CHAIN) during the 2008–2009 solar minimum.

Spatial and Temporal Evolution of Different‐Scale Ionospheric Irregularities in Central and East Siberia During the 27–28 May 2017 Geomagnetic Storm

Space Weather, 2020
We present a multi‐instrumental study of ionospheric irregularities of different scales (from tens of centimeters to few kilometers) observed over the Central and East Siberia, Russia, during a moderate‐to‐strong geomagnetic storm on 27–28 May 2017. From

The climatology of ionospheric plasma bubbles and irregularities over Brazil [PDF]

Annales Geophysicae, 2005
In this paper, we examine ionospheric plasma depletions (or bubbles) and irregularities observed by photometers and a ground-based receiver of the global positioning system (GPS) both located in Brazil, South America.

A measure of ionospheric irregularities: zonal velocity and its implications for L-band scintillation at low-latitudes

Earth and Planetary Physics, 2021
We estimate the zonal drift velocity of small-scale ionospheric irregularities at low latitude by leveraging the spaced-receivers technique applied to two GNSS receivers for scintillation monitoring installed along the magnetic parallel passing in ...
