Behavior of Evaporation Ducts in Stable and Unstable Surface Layers

Radio Science, Volume 61, Issue 2, February 2026.
Abstract The atmospheric surface layer over the ocean has a strong impact on electromagnetic (EM) wave propagation in the lowest 100 m of the atmosphere. Due to surface evaporation, a strong vertical gradient in water vapor forms in this layer, resulting in an evaporation duct which may greatly increase detection ranges for sensors and targets within ...

Real Heights of SuperDARN F Region Echoes Inferred From Electron Density Measurements by the Rankin Inlet and RISR‐C Radars

Radio Science, Volume 61, Issue 2, February 2026.
Abstract This study is one of the first attempts to estimate statistically the real height of SuperDARN F region echoes in the polar cap. To achieve this, measurements of the electron density in the scattering volume of the Rankin Inlet SuperDARN radar are compared with the electron density profiles measured by the incoherent scatter radar RISR‐C ...

Six‐Component Electromagnetic Wave Measurements of Sprite‐Associated Lightning

Radio Science, Volume 61, Issue 2, February 2026.
Abstract Low frequency electromagnetic waves emitted by sprite‐producing lightning are normally measured using vertical electric fields or horizontal magnetic fields. Here we report for the first time the simultaneous measurement of electromagnetic waves from sprite‐producing lightning in all six electromagnetic field components Ex,Ey,Ez,Hx,Hy,andHz ...
