Effects of stratospheric ozone recovery on photochemistry and ozone air quality in the troposphere [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
There has been significant stratospheric ozone depletion since the late 1970s due to ozone-depleting substances (ODSs). With the implementation of the Montreal Protocol and its amendments and adjustments, stratospheric ozone is expected to recover ...

Zonally asymmetric influences of the quasi-biennial oscillation on stratospheric ozone [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
The quasi-biennial oscillation (QBO), as the dominant mode in the equatorial stratosphere, modulates the dynamical circulation and the distribution of trace gases in the stratosphere.

Surface ozone over the Tibetan Plateau controlled by stratospheric intrusion [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
The Tibetan Plateau is a global hotspot of stratospheric intrusion, and elevated surface ozone was observed at ground monitoring sites. Still, links between the variability of surface ozone and stratospheric intrusion at the regional scale remain unclear.

The role of tropical upwelling in explaining discrepancies between recent modeled and observed lower-stratospheric ozone trends [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
Several analyses of satellite-based ozone measurements have reported that lower-stratospheric ozone has declined since the late 1990s. In contrast to this, lower-stratospheric ozone was found to be increasing in specified-dynamics (SD) simulations from ...

Transport of substantial stratospheric ozone to the surface by a dying typhoon and shallow convection [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
Stratospheric ozone transported to the troposphere is estimated to account for 5 %–15 % of the tropospheric ozone sources. However, the chances of intruded stratospheric ozone reaching the surface are low.

The Simplified Chemistry-Dynamical Model (SCDM V1.0) [PDF]

open access: yesGeoscientific Model Development, 2021
Recent observational and modeling studies show that variations of stratospheric ozone and the resulting interaction between ozone and the stratospheric circulation play an important role in surface weather and climate.

A stratospheric prognostic ozone for seamless Earth system models: performance, impacts and future [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
We have implemented a new stratospheric ozone model in the European Centre for Medium-Range Weather Forecasts (ECMWF) system and tested its performance for different timescales to assess the impact of stratospheric ozone on meteorological fields. We have

Influence of Stratospheric Ozone Changes on Stratospheric Temperature Trends in Recent Decades

open access: yesRemote Sensing, 2022
Associated with the recovery of stratospheric ozone, stratospheric cooling has decelerated since the late 1990s. This study investigates the contribution of ozone changes to the long-term stratospheric temperature trends in recent decades using satellite

Reformulating the bromine alpha factor and equivalent effective stratospheric chlorine (EESC): evolution of ozone destruction rates of bromine and chlorine in future climate scenarios [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
Future trajectories of the stratospheric trace gas background will alter the rates of bromine- and chlorine-mediated catalytic ozone destruction via changes in the partitioning of inorganic halogen reservoirs and the underlying temperature structure of ...

Effects of Arctic ozone on the stratospheric spring onset and its surface impact [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
Ozone in the Arctic stratosphere is subject to large interannual variability, driven by both chemical ozone depletion and dynamical variability. Anomalies in Arctic stratospheric ozone become particularly important in spring, when returning sunlight ...
