Statistical Study on the Effect of Meridional Neutral Wind on the Occurrence of Post‐Sunset Equatorial Ionospheric Irregularities

Space Weather
The navigation and radio communication systems experience significant disruptions due to post‐sunset equatorial ionospheric irregularities. There is ongoing debate regarding the impact of meridional/trans‐equatorial wind speed on these irregularities ...

Saturn's Ionosphere: Some Evidence of Equatorial Anomaly [PDF]

, 1985
143-146Electron density profiles obtained from radio science experiments on Pioneer-11, Voyager-1 and Voyager-2 have been analyzed to look for equatorial anomaly in the ionosphere of Saturn. Although there is no measurement right at the magnetic equator,

O I 630.0-nm dayglow in the region of equatorial ionization anomaly: temporal variability and its causative mechanism

, 1992
Results of the continuous measurements of O I 630.0-nm dayglow from Mount Abu (20° 20' N dip latitude), a station in the region of equatorial ionization anomaly (EIA) by means of a recently developed ground-based dayglow photometer are presented.

Temporal Variability of Equatorial Ionization Anomaly Crest Locations Extracted From Global Ionospheric Maps

Space Weather
The Equatorial Ionization Anomaly (EIA) crest location is known to vary over a variety of temporal scales. For the first time we perform a statistical survey of the temporal variation of the EIA crest location viewed globally and spanning 20 years.

Topside Ionosphere During the Mother's Day Superstorm as Observed by Multiple LEO Spacecraft, Including SNIPE

Space Weather
We analyze the topside electron density and temperature during the superstorm in May 2024 (Mother's Day storm or Gannon storm), using multiple Low‐Earth Orbit (LEO) spacecraft operating at different altitudes, such as Swarm, International Space Station ...

Saturn's Ionosphere: Further Evidence of Equatorial Anomaly [PDF]

, 1986
61-62Electron density profile measured at 1ᵒS by the Radio Science Experiment on Voyager 1 indicates a depleted equatorial inonosphere at Saturn. The value of the peak electron density on this measurement is quite close to the one speculated by us ...
