Scientists Captured the First Glimpse of a Rare Polar Aurora
After a decade-long search, scientists captured a type of elusive aurora on camera.
New Method Reveals Hidden Structures in Clear-Sky Vertical Motion
High-resolution satellite data reveal unexpected, highly heterogeneous vertical motions in the clear-sky atmosphere, with a new method proposed for measuring these motions.
Cloud Brightening Could Have Unintended Effects in a Warming World
New research shows that though marine cloud brightening holds potential to temporarily reduce heat stress regionally, the technique has unpredictable and far-reaching outcomes.
How Great was the “Great Oxidation Event”?
Geochemical sleuthing amid acid mine runoff suggests that scientists should rethink an isotope signal long taken to indicate low levels of atmospheric oxygen in Earth’s deep past.
Buffering by Ammonia Sustains Sulfate Aerosol Production
A new method for evaluating the role of multiphase buffering and acidification reactions on aerosol pH finds that the buffering effect sustains sulfate production from high pH-favored multiphase reactions.
Ocean Impacts on European Winter Weather
State-of-the-art high-resolution models are needed to reveal the ocean’s role in driving extra-tropical weather systems.
The Invisible Hand of Carbon Dioxide on Forest Productivity
A statistically robust approach applied to long-term flux measurements quantifies forest ecosystem response to increasing atmospheric carbon dioxide, providing a valuable benchmark for climate models.
Machine Learning Masters Weather Prediction
Community datasets and evaluation standards are needed to further advance machine learning for weather prediction.
New Observations Provide Insight into Soil Desiccation Cracking
A new application of distributed fiber optic sensing provides early detection of soil desiccation cracking behavior and illustrates, for the first time, the phenomenon of soil crack breathing.
