Imperfect knowledge of high-latitude forcing of the coupled ionosphere-theremosphere system translates into uncertainty in the low-latitude and midlatitude response to a geomagnetic storm.Read More �
Layered-ejecta craters on Mars that are associated with impacts into rock mixed with volatiles have been formed throughout the planet’s history indicating the long-term preservation of subsurface ice.Read More �
Most fast coronal mass ejections will be decelerated into ambient solar wind quickly in the inner heliosphere, but some of them continue the deceleration with an even larger amplitude beyond 1 AU.Read More �
Satellites designed to observe ocean winds can also be used to map both forest structure and water content, allowing researchers to disentangle factors of carbon loss due to drought in the Amazon.Read More �
A new model of geomagnetically induced currents revisits how space weather damaged a New Zealand grid transformer in 2001, and shows how much worse it could be in a space weather superstorm.Read More �
Coastal California fog—a key source of water for the iconic redwood tree—has declined by a third. Can a trace gas, carbonyl sulfide, be used to assess the effect on plant productivity?Read More �
The first observational evidence of dipole eddy pairs (modons) in the southern midlatitude ocean reveals that they move faster, live longer, and travel greater distances compared to single eddies.Read More �
Space weather forecasting is benefiting, and can benefit much further, from concepts and tools already developed by the global meteorological community.Read More �
Understanding changing conditions in the south polar oceans during the warm late Pliocene period may help predict the impact of contemporary warming.Read More �
Cross-tropopause ozone transport in midlatitude cyclones, coincident with dry air intrusions, is derived from satellite and reanalysis data organized in cyclone-centric coordinates.Read More �
