Researchers have developed a new mathematical model to more accurately capture how irregularities in Earth’s atmosphere interrupt signals from Global Navigation Satellite Systems.
Charged particles escape our atmosphere following Earth’s magnetic field and constitute a main source of matter that modulates Sun-Earth interactions.
Researchers present a new pattern-finding technique to better estimate missing data on ionospheric plasma velocities.
Hydrological observations of cosmic ray neutrons scattered by water in soil can also provide information on space weather events such as Forbush decreases and ground level enhancements.
Tamas I. Gombosi was awarded the 2020 John Adam Fleming Medal at the virtual AGU Fall Meeting in December. The medal is for “original research and technical leadership in geomagnetism, atmospheric electricity, aeronomy, space physics, and/or related sciences.”
Tiny magnetometers have turned your phone into a compass, and new research shows they are sensitive to geomagnetic storms.
A versatile suite of computational models, already used to forecast magnetic storms and potential power grid and telecommunications disruptions, is preparing to welcome a larger group of users.
Solar radio bursts are background noise for satellite-based radio observations that monitor soil moisture, so, with appropriate processing, those observations can provide data on radio bursts.
Solar-induced geomagnetic activity and mass strandings of whales and dolphins on shorelines both show seasonal patterns, but the beachings likely result from multiple environmental factors.
Heliospheric imaging data can be used in ensemble modeling of CME arrival time at Earth to improve space weather forecasts, treating the solar wind as a 1-D incompressible hydrodynamic flow.
