Solar energetic particle events pose an acute risk to space travelers outside the protection of Earth’s magnetic field. A new initiative aims to quantify the danger.Read More »
A new simulation of the Earth’s electron radiation belts captures large-scale variations over nearly three solar cycles, and replicates primary cyclical features and extreme behaviors.Read More »Space Science & Space Physics
Dense GNSS networks enable scientists to track large-scale waves traveling through the upper atmosphere, away from sources in the auroral zone and the day/night terminator.Read More »Space Science & Space Physics
Protons accelerated in solar storms and electrons accelerated in geospace storms can reduce space mission lifetimes. What is the likelihood of extreme events during geospace storms?Read More »Natural Hazards
Weather forecasts combine many model predictions to create an ensemble that is more accurate than separate models, a technique now starting to be applied in space weather science.Read More »Space Science & Space Physics
Ensemble techniques are opening a path toward space weather forecasts that give deeper understanding of the risk posed by each solar storm that approaches our planet.Read More »Natural Hazards
Very low frequency radio, a well-proven tool for solar-terrestrial studies, proves to be adept at detecting the stresses that space weather imposes on the transformers at the heart of power grids.Read More »Natural Hazards
Solar wind drivers affecting the satellite environment have about a one hour predictive horizon, but solar wind speed periodicities and ensemble modeling can extend the forecast interval.Read More »
