Fault Maturity or Orientation: Which Matters More for Quakes?
Close examination of a 2021 earthquake on the Tibetan Plateau provides hints that, counter to prior assumptions, the influence of fault orientation can sometimes trump that of maturity.
Low-Level Clouds Disappear During a Solar Eclipse
Cumulus clouds rapidly dissipate as the land surface cools, a finding that has implications for Sun-obscuring geoengineering efforts.
Monitoring Polar Ice Change in the Twilight Zone
Landsat’s new extended data collection program is mapping Arctic and Antarctic regions year-round, even in polar twilight.
Accounting for Small-Scale Processes in Large-Scale Models
A new book explores how fast processes can be better represented in atmospheric models to improve weather and climate prediction.
Trustworthy Satellite Earth Observations for Science and Society
Enhancing confidence in satellite observations of terrestrial properties like land surface temperature and soil moisture requires advances in validation and data quality assessment practices.
Plants Reveal the History of Earth’s Largest Tropical Ice Cap
Rooted plants buried by advancing outlet glaciers illustrate rapid changes in the extent of Quelccaya Ice Cap in Peru during the Holocene.
Ecosystem Observations from Every Angle
Proximal remote sensing provides a bridge between ecosystem flux data at Earth’s surface and optical data from satellite sensors, improving our grasp of feedbacks between terrestrial ecosystems and climate.
Satellites Map Environmental Vulnerabilities in U.S. Prisons
Geoscientists are using remote sensing to gather data on risks including increased exposure to air and soil pollution, excessive heat, wildfire, and flooding.
Humans Have Boosted Atmospheric Mercury Concentrations Sevenfold
A new baseline of volcanic contributions to the global mercury cycle reveals how drastically human activities have increased the element’s concentration in the atmosphere.
