Understanding High-Energy Physics in Earth’s Atmosphere
Thunderstorms present a variety of hazards, including emissions of ionizing radiation. An international group of scientists met at an Armenian observatory to share their findings.
Podcast: A Nuclear Legacy Buried in Ice
The radioactive remains of nuclear testing during the Cold War and from nuclear disasters like Chernobyl are still with us and can be found in some of the remotest glaciers on Earth.
Human-made Emissions Modify Electron Space Environment
Very Low Frequency transmitters used for communications with submarines modify the dynamics of energetic electrons in the inner radiation belt and the slot region.
Bruce Barkstrom (1944–2018)
Bruce R. Barkstrom, principal investigator for NASA missions involved with understanding Earth’s radiation budget, committed his life to analyzing, interpreting, and stewarding Earth science data.
First Multi-Decade Simulation of the Earth’s Radiation Belt
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.
Catching the Oncoming Radiation Storm
Improved processing enables satellite-based radiation sensors to match ground-based sensors in providing prompt warnings of the onset of atmospheric radiation storms that can endanger civil aviation.
Increasing Radiation Levels May Challenge Space Exploration
New research shows that solar radiation levels are growing 10% faster than previously believed and that the radiation environment in space will worsen with time.
