The “age of stratospheric air” measures the speed of the global transport circulation in the stratosphere, which is crucial for understanding the distribution of important trace gases, like ozone.

Better Monitoring is Needed for Climate Change in the Upper Atmosphere
A new commentary calls for a better understanding of the impacts of climate change and anthropogenic emissions on long-term trends of the middle and upper atmosphere through enhanced observations and monitoring capabilities.
Simulating a Unique Wind System in a Kilometer-Scale Model
A new study shows that a kilometer-scale model can directly simulate aspects of the Quasi-Biennial Oscillation.
Five Decades of Stratospheric Aerosols from Balloon Measurements
Long-term global measurements of stratospheric aerosols reveal climatological structures and processes controlling new particle formation.
Atmospheric Effects of Hunga Tonga Eruption Lingered for Years
A new study builds on previous research of the underwater volcano’s effects on the climate.
What Happens in the Troposphere Doesn’t Stay in the Troposphere
A new study suggests that spillover of tropospheric ozone is affecting measurements of stratospheric ozone recovery more than previously realized.
Uncertainty Abounds in Seeding the Sky to Fight Climate Change
Some scientists have suggested injecting solid particles such as alumina, calcite, or even diamonds into the atmosphere to temporarily limit climate warming. But new research shows there are still big unknowns.
Spacecraft Are Sprinkling the Stratosphere with Metal
Metals from spacecraft reentry don’t simply vaporize and vanish. Scientists found them in the stratosphere.
Modeling Stratospheric Impacts on North American Extreme Events
A new study quantifies the tropospheric and surface impacts of extreme stratospheric wave events and evaluates their representation in state-of-the-art climate models.
Quantifying Extreme Events from Short Weather Forecast Data
Subseasonal weather forecast ensembles are a useful tool for overcoming the inherent difficulty of quantifying extreme weather risk caused by data scarcity.
