The three-dimensional distribution of electron density in the Earth’s ionosphere could be obtained using the broadband radiation of naturally occurring lightning discharges.Read More �
Both simulations and observations are used to measure the magnetic reconnection rate in the Earth’s magnetotail, suggesting that the rate is correlated with the intensity of a magnetic substorm.Read More �
Cloud retrievals for partly cloudy pixels might be able to be improved by using high-resolution samples in a visible to near-infrared band, which many satellite sensors offer.Read More �
An evolving set of tools helps land surface model developers optimize the realism of their parameterizations for the next generation of weather and climate models.Read More �
Samoan corals record how patterns of warm/cool and more/less salty in the equatorial Pacific changed in space and time over the last 500 years.Read More �
Naturally generated seismic waves bouncing up and down through an ice sheet can be used to determine the thickness of the ice and monitor future changes in ice thickness.Read More �
The bright aurorae dancing in the sky are produced by charged particles traveling along the magnetic field lines from tens of planetary radii. By why do aurorae rotate at Saturn but not at Earth?Read More �
Two lightning flashes were observed in the same location: One produced a bright gamma-ray flash with about 1000 counts per millisecond, but the other did not.Read More �
