Precipitations of electrons with energies greater than 30 kiloelectron volts from the slot region penetrate at low altitude and can contribute to destroy ozone.Read More �
River systems are affected by societies against a backdrop of climate change. A new dataset reveals how these forces affect river flow, chemistry, and the biological health of the river.Read More �
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 �
Clear air policies have led to dramatic reductions in acid rain and improved ecosystem health, but it now appears that climate change could counteract those gains.Read More �
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 �
Polar vortices play a central role in coupling the atmosphere from the ground to the middle atmosphere. New satellite diagnostics describe mesospheric polar vortices and coupling to lower altitudes.Read More �
Low-salinity water from the Ganga-Brahmaputra river is transported by mesoscale eddies in the Bay of Bengal, but when the monsoon winds strengthen, a shallow “Ekman” flow dominates dispersal of water.Read More �
Rarely made detailed measurements of carbon dioxide and methane under lake ice reveal a story more complex than simple models of gas buildup, with surprising findings for climate change impacts.Read More �
