A new measurement capability can detect the polarization of the radio frequency wave of lightning sources, which reveals different forms of lightning breakdown processes.
Equatorial Ionospheric Scintillation During Daytime
Scintillation—flickers and distortions in radio waves passing through the ionosphere—can happen during daytime and at much lower dip latitudes than previously thought.
Meteors Can be Used to Calibrate a Radar System
Every day meteors burn up in the atmosphere with highly predictable results, reflecting radio waves that could be used to calibrate antennas.
How to Build a Better Light Trap
Nanosized chambers capture bits of light for infinite amounts of time.
Managing Radio Traffic Jams with the Cloud
Sensor networks and data mining allow for fully automated, real-time monitoring of radio waves.
Mystery of the Ionosphere’s “Gyro Line” Solved
A new study provides an updated hypothesis to describe a unique radar signature from plasma waves high above Earth, correcting errors that had stood for decades.
Tracking Meteor Trails to Study the Mesosphere
Twelve years of radar data reveal new phenomena in Earth’s upper atmosphere.
Radio Science and Space Weather Now Available on IEEE Xplore
Two AGU journals are poised to reach a broader audience.
Earthquakes Could Funnel Radio Waves to Dark Zones in Mountains
By being coupled with a layer of mobile electrical charges on the Earth's surface, radio waves could travel over the ground to areas that would normally be unreachable, like behind a mountain.
Forecasting Space Weather Like Earth Weather
Researchers find that as with terrestrial weather, ensemble forecasting—which uses several different models simultaneously—is the best way to produce accurate and precise forecasts of space weather.
