Evidence and Causes of an Unusual Super Plasma Bubble Occurrence During Weak Geomagnetic Conditions Over Europe

Space Weather, Volume 24, Issue 1, January 2026.
Abstract Using data from a cluster of ground‐based global navigation satellite system, we observed spatially extended enhanced ROTI over the European longitudes during a weak geomagnetic storm (Dst ≈ ${\approx} $ −50 nT) on 4 November 2023. The enhanced ROTI is extended over an extensive geographical latitudinal range of 46°N.

Comparative Analysis of Ionospheric Responses to Ultra‐Fast Kelvin Waves With Wavenumbers 1, 2, and 3

Space Weather, Volume 24, Issue 1, January 2026.
Abstract We employed zonal wind data from Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics Doppler Interferometer, equatorial electrojet (EEJ) measurements from Jicamarca (12°S, 77°W), and global ionospheric total electron content (TEC) maps to investigate the effects of ultra‐fast Kelvin waves (UFKW) with zonal wavenumbers 2 and 3 ...

Impacts of Space Weather‐Induced Satellite Navigation Errors on UAV Path Planning and Energy Consumption

Space Weather, Volume 24, Issue 1, January 2026.
Abstract Space weather disturbances can degrade satellite navigation accuracy, posing operational challenges for Unmanned Aerial Vehicle (UAV) missions that require precise path planning. This study investigates the impact of space weather‐induced horizontal navigation errors on UAV flight distance and energy consumption through a simulation‐based ...

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 ...

InSAR Ground Deformation and Pumping Energy Consumption Reveal Urban Water Security

Water Resources Research, Volume 62, Issue 1, January 2026.
Abstract Water resource assessments are critical for ensuring water security (WS), particularly in rapidly urbanizing regions with increasing water demand and limited water monitoring capabilities. Earth observations and indirect indicators of surface and groundwater changes are valuable tools for developing such assessments.
