Investigation of the relationship between the spatial gradient of total electron content (TEC) between two nearby stations and the occurrence of ionospheric irregularities

, 2019
. The relation between the occurrence of ionospheric irregularities and the spatial gradient of total electron content (TEC) derived from two closely located stations (ASAB: 4.34 ∘  N, 114.39 ∘  E and DEBK: 3.71 ∘  N, 109.34 ∘  E, geomagnetic), located ...

Forecasting Equatorial Plasma Bubbles From Precursor TEC Signatures Observed by C/NOFS

Space Weather, Volume 24, Issue 1, January 2026.
Abstract This study investigates the potential of localized total electron content (TEC) perturbation measurements, possibly associated with bottomside upwelling of the F‐layer, as precursors for forecasting ionospheric plasma irregularities, particularly the equatorial plasma bubbles (EPBs).

Leveraging ROTI map derived from Indonesian GNSS receiver network for advancing study of Equatorial Plasma Bubble in Southeast/East Asia

Earth and Planetary Physics
This paper highlights the crucial role of Indonesia’s GNSS receiver network in advancing Equatorial Plasma Bubble (EPB) studies in Southeast and East Asia, as ionospheric irregularities within EPB can disrupt GNSS signals and degrade positioning accuracy.

Space Weather and Low‐Altitude Drone Economy

Space Weather, Volume 24, Issue 1, January 2026.
Abstract Unmanned Aerial Vehicles (UAVs) are becoming integral to the emerging low‐altitude economy, operating primarily below 3,000 m for applications such as logistics, inspection, precision agriculture, and urban air mobility. The safe and reliable operation of UAVs depends critically on communication, navigation, and surveillance (CNS) systems ...

Upwelling Metallic Ions Producing Valley Region Irregularities Over Low Latitude During the 2025 New Year Magnetic Storm

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Valley region irregularities (VRIs) have been previously investigated using radar, ionosonde, and rocket‐borne in situ observations. In this paper, based on a joint observational experiment by lidar and radars performed in Hainan, China, we report a case of low‐latitude VRIs generated in association with uplifted metallic ions for the first ...

The Global Propagation of Hiss Waves Originating From Dynamic Plasmaspheric Plume

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Hiss waves play a critical role in shaping Earth's radiation belts and mediating magnetosphere‐ionosphere energy transfer. Intense hiss emissions are frequently generated within dynamic plasmaspheric plumes through linear and nonlinear wave‐particle interactions.
