Lyman-alpha emissions convey a major part of the solar-flare photon energy reaching Earth and play a significant role in flare-driven enhancements of ionospheric conductivity.
An innovative clinical trial uses “two-way participation” between Navajo and medical communities to study the impact of zinc on mitigating health effects associated with uranium mining.
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.
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 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.
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.
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.
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.
Exploring the relationship between solar extreme ultraviolet radiation flux and 150-km radar echoes.
New calculations show that lightning-triggered plasma waves in Earth's magnetosphere absorb energy from slow particles and energize electrons to levels that can damage satellites severely.
