Age of stratospheric air is a well established metric for the stratospheric transport circulation.
Rooted in a robust theoretical framework, this approach offers the benefit of being deducible …

The Brewer–Dobson circulation (BDC) is a key feature of the stratosphere that models need
to accurately represent in order to simulate surface climate variability and change …

The Montreal Protocol, and its subsequent amendments, has successfully prevented
catastrophic losses of stratospheric ozone, and signs of recovery are now evident …

In response to global warming, ozone is predicted to increase aloft due to stratospheric
cooling but decrease in the tropical lower stratosphere. The ozone reductions have been …

This study investigates changes in stratosphere‐troposphere exchange (STE) of air masses
and ozone concentrations from 1960 to 2099 using multiple model simulations from …

Simulating whole atmosphere dynamics, chemistry, and physics is computationally
expensive. It can require high vertical resolution throughout the middle and upper …

Despite decades of effort, the drivers of global long-term trends in tropospheric ozone are
not well understood, impacting estimates of ozone radiative forcing and the global ozone …

Changes in stratospheric ozone concentrations and increasing concentrations of
greenhouse gases (GHGs) alter the temperature structure of the atmosphere and drive …

We perform the first multi-model intercomparison of the impact of nudged meteorology on
the stratospheric residual circulation using hindcast simulations from the Chemistry–Climate …

Recent observations show a significant decrease in lower-stratospheric (LS) ozone
concentrations in tropical and mid-latitude regions since 1998. By analysing 31 chemistry …
