Combined Measurement of Soil Permittivity and Electrical Conductivity Using UAV‐Based Ground Penetrating Radar

open access: yesWater Resources Research, Volume 61, Issue 10, October 2025.
Abstract Measurements of soil water content and salinity are important for a wide range of topics, in particular those concerned with soil and plant health, and specific aspects of agricultural management. However, most traditional methods are unsuitable for simultaneously mapping the field scale variability of soil electrical properties. In this study,

Quasi‐Constant Time Gap in Multiple Rings of Elves

open access: yesEarth and Space Science, Volume 12, Issue 10, October 2025.
Abstract We present evidence that the time delay between the multiple rings of elves is not caused by the ground reflection of the electromagnetic pulse produced by intracloud lightning. To investigate temporal differences of multi‐elves, we analyzed data from four storms occurring at various times and distances from the Pierre Auger Observatory in ...

Enhanced Radiation at Aviation Altitudes and Plasmaspheric Hiss Waves—A Time Shift Analysis

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Increased radiation levels in Earth's atmosphere can present significant risks to airline pilots, passengers, and commercial space travelers. Recent findings have revealed a strong statistical link between radiation dose rates detected at aviation altitudes (>9 ${ >} 9$km) and plasmaspheric hiss wave power observed along the same magnetic ...
