Low-latitude scintillation occurrences around the equatorial anomaly crest over Indonesia [PDF]
, 2014 We investigated low-latitude ionospheric scintillation in Indonesia using two GPS receivers installed at Bandung (107.6° E, 6.9° S; magnetic latitude 17.5° S) and Pontianak (109.3° E, 0.02° S; magnetic latitude 8.9° S).

Wave‐Based Quantification of Ion Composition in the Earth's Magnetosphere‐Ionosphere‐Coupling Region
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Ion composition critically determines the basic kinetic characteristics of plasma and affects energy transmission of the magnetosphere. However, it exhibits significant variations with altitude, latitude, local time, longitude, and also with geomagnetic and solar activity.

Dataset of Quiet Space Weather Periods for Ionospheric Studies
Earth and Space Science, Volume 13, Issue 4, April 2026.Abstract The ionosphere is a dynamic environment regularly affected from above and from below. This study identifies periods within the years 2000–2023 when the impact from above, driven by space weather, was minimal. The quiet space weather periods have wide usage for two types of ionospheric studies. At first, studies of isolated space weather events

The ionospheric scintillation phenomenon
, 2022 The SAGAIE network was deployed in West-Africa in 2013 to assess the feasibility of an equatorial for ASECNA SBAS by studying ionospheric scintillation. This study of the network’s measurements, taken between 2013 and 2016, analyzes the characteristics of the scintillation recorded by five receivers that cover Sub-Saharan West-Africa.

Space Weather, Volume 24, Issue 4, April 2026.Abstract The total solar eclipse on 8 April 2024 provided a unique opportunity to investigate the three‐dimensional (3‐D) ionospheric response under enhanced solar activity over North America. In this study, we processed high‐density GNSS observations from ∼1,700 stations to derive vertical total electron content and applied a multi‐term sinusoidal ...

Climatology of Plasma Irregularities Using ROTI Index From 2008 to 2023 in East West Asia
Space Weather, Volume 24, Issue 4, April 2026.Abstract This study investigates characteristics of ionospheric irregularities over the East–West Asian equatorial region using the Rate of TEC Index (ROTI) derived from Global Navigation Satellite System (GNSS) measurements. Data from four stations (GUAM, PIMO, CUSV, and IISC) were analyzed for 2008–2023, covering solar cycle (SC) 24 and the ascending

Characteristics of VHF scintillations in the equatorial anomaly crest region in India [PDF]
Annales Geophysicae, 1995 The characteristics of ionospheric scintillations at Rajkot in the equatorial anomaly crest region in India are described for the years 1987–1991 by monitoring the 244-MHz transmission from the satellite FLEETSAT.
