Scientists combined 82 satellite years of data to create a more comprehensive model of how plasma behaves in a region of Earth's magnetosphere with heavy spacecraft traffic.
Hazards & Disasters
Position Statement on Hazards: Call for Comments
Feedback sought from American Geophysical Union members until 30 September on draft statement emphasizing partnering of scientists, policy makers, and stakeholders to improve hazards resilience.
A Weather Eye on Coastal Winds
New satellite radar image-processing system provides wind speed maps with an unprecedented degree of precision. Such maps will help coastal communities prepare for wind-related hazards.
Does U.S. Hurricane Rating Scale Get the Danger Right?
Some scientists think it's time to retire the Saffir-Simpson scale and start fresh.
Ten Years After Katrina: What Have We Learned?
One mitigation strategy—relocating people and sensitive infrastructure to higher ground—eventually will need to be considered as sea level rise accelerates.
What Lies Deep in the Mantle Below?
For decades, scientists have probed Earth's remote mantle by analyzing how seismic waves of distant earthquakes pass through it. But we are still challenged by the technique's limitations.
