Unusual Enhancement of Midlatitude Sporadic-E Layers in Response to a Minor Geomagnetic Storm
Atmosphere, 2022 This study investigates the variations of middle and low latitude sporadic-E (Es) layers in response to a geomagnetic storm. Es layers are observed by five ionosondes located in the Eastern Asian sector.

Sounding of sporadic E layers from China Seismo-Electromagnetic Satellite (CSES) radio occultation and comparing with ionosonde measurements [PDF]
Annales Geophysicae, 2022 GNSS radio occultation (RO) plays an important role in ionospheric electron density inversion and sounding of sporadic E layers. As China's first electromagnetic satellite, China Seismo-Electromagnetic Satellite (CSES) has collected the RO data from both

Numerical prediction of sporadic E layer occurrence using GAIA [PDF]
Earth, Planets and Space, 2021 A sporadic E layer has significant influence on radio communications and broadcasting, and predicting the occurrence of sporadic E layers is one of the most important issues in space weather forecast.

Morphology of sporadic E layers derived from Fengyun-3C GPS radio occultation measurements
Earth, Planets and Space, 2022 The Global Positioning System (GPS) radio occultation (RO) data provided by the Fengyun-3C (FY-3C) mission during January 2015 to December 2019 are used to detect the existence of sporadic E (Es) layers over the globe, based on which the spatial and ...

Consolidated Amateur Radio Signal Reports as Indicators of Intense Sporadic E Layers
Atmosphere, 2022 A case study is presented which demonstrates the value and validity of a novel approach to the use of consolidated amateur (‘ham’) radio reception reports as indicators of the presence of intense ionospheric sporadic E (Es).

Modulation of sporadic E layers by small-scale atmospheric waves in Earth’s high-latitude ionosphere
Solar-Terrestrial Physics, 2019 We have used radio occultation measurements of the satellite CHAMP (Challenging Minisatellite Payload) to examine sporadic E layers (altitudes 90–130 km) in Earth’s high-latitude ionosphere.

Terdiurnal signatures in sporadic E layers at midlatitudes [PDF]
Advances in Radio Science, 2013 Global Positioning System radio occultation measurements by the FORMOsa SATellite mission-3/Constellation Observing System for Meteorology, Ionosphere and Climate satellites were used to analyse the behaviour of the signature of the terdiurnal tide in ...

Seasonal variability and descent of mid-latitude sporadic E layers at Arecibo [PDF]
Annales Geophysicae, 2009 Sporadic E layers (Es) follow regular daily patterns in variability and altitude descent, which are determined primarily by the vertical tidal wind shears in the lower thermosphere.
