Missing Lakes Under Antarctic Ice Sheets
New radio sounding study finds little evidence of lakes under Antarctica’s Recovery Glacier.
Subglacial Water Can Accelerate East Antarctic Glacier Flow
Airborne radar from the Recovery Glacier system demonstrates the importance of characterizing the underlying causes of ice flow speedup to understand how glacial discharge could change in the future.
New Antenna Design Could Improve Satellite Communications
A novel antenna design promises to improve bandwidth and allow for better communication between Earth stations and satellites.
Westward Expansion, Technology, and Tornado Fatalities
By mining records from 1808 to 2017, researchers can now show just how many lives have likely been saved by technology like radar.
Diurnal Variation of Rainfall over the Equator Revisited
Radar data show an afternoon precipitation maximum in the equatorial Indian Ocean in addition to the nocturnal maximum; this occurs under light surface winds and suppressed large-scale convection.
Wireless Frequency Sharing May Impede Weather Satellite Signals
The delivery of weather satellite imagery is reliable today, but will it stay that way in the future?
Continental Convection Reaches New Highs
Ten years of high-resolution gridded NEXRAD radar data provide a new data set to quantify tropopause-overshooting convection over the continental United States.
A Decade of Atmospheric Data Aids Black Hole Observers
Astrophysicists are using a global atmospheric model to help them coordinate a multicontinent, radio-frequency observing campaign to gaze at the black hole at the center of the Milky Way.
New Observations of Mysterious Radar Echoes
Exploring the relationship between solar extreme ultraviolet radiation flux and 150-km radar echoes.
