Undisturbed tropical rain forests are experiencing more frequent droughts, but the ecosystems are isolated and difficult to assess. Scientists are using remote sensing to expand the depth and scope of monitoring efforts.
The most powerful gigantic jet ever recorded fortuitously appeared over a sensor array in Oklahoma, enabling scientists to map the structure of the phenomenon for the first time.
A new-generation weather radar and a massive supercomputing system enables forecasts of storms refreshed every 30 seconds, a significant development in severe weather prediction.
Altitude-resolved S-band radar observations of graupel are used to decipher thunderstorm ground enhancements in surface electric field and gamma ray flux.
Scientists dive in—metaphorically—to Lake Snow Eagle, only recently revealed through ice-penetrating radar.
Amateur radio observations provide a new method for studying large-scale ionospheric disturbances and HF communication impacts, and are important applications in ionospheric space weather monitoring.
Greenland’s Hiawatha impact structure, more than 30 kilometers in diameter, is much older than previously thought, new results suggest.
Dual‐frequency Precipitation Radar observations reveal the characteristics and microphysical processes of the melting layer in cyclone precipitation over the western North Pacific.
Atmospheric winds moving at more than 7,000 kilometers per hour distort Saturn’s magnetic field, revealing why spacecraft have measured changes in the length of a day on the ringed world.
Stunning images of the center of the Milky Way showcase technology and techniques that may be a starting point for more discoveries.
