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

Atmospheric 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

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

Atmospheric 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 ...

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]

Atmospheric 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 ...

Influence of Arctic stratospheric ozone on surface climate in CCMI models [PDF]

Atmospheric Chemistry and Physics, 2019
The Northern Hemisphere and tropical circulation response to interannual variability in Arctic stratospheric ozone is analyzed in a set of the latest model simulations archived for the Chemistry-Climate Model Initiative (CCMI) project.

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

Atmospheric 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 ...

Stratospheric influences on surface ozone increase during the COVID-19 lockdown over northern China

npj Climate and Atmospheric Science, 2023
Surface ozone increased unexpectedly over northern China during the COVID-19 lockdown (CLD) period (23 January–29 February 2020), which was characterized by vigorous emission reduction.

Chemical transport model ozone simulations for spring 2001 over the western Pacific : comparisons with TRACE-P lidar, ozonesondes, and Total Ozone Mapping Spectrometer columns [PDF]

, 2003
Two closely related chemical transport models (CTMs) employing the same high-resolution meteorological data (similar to180 km x similar to180 km x similar to600 m) from the European Centre for Medium-Range Weather Forecasts are used to simulate the ozone

Stratospheric impact on tropospheric ozone variability and trends: 1990–2009 [PDF]

Atmospheric Chemistry and Physics, 2013
The influence of stratospheric ozone on the interannual variability and trends in tropospheric ozone is evaluated between 30 and 90° N from 1990–2009 using ozone measurements and a global chemical transport model, the Community Atmospheric Model with ...

Radiative forcing in the 21st century due to ozone changes in the troposphere and the lower stratosphere [PDF]

, 2003
Radiative forcing due to changes in ozone is expected for the 21st century. An assessment on changes in the tropospheric oxidative state through a model intercomparison ("OxComp'') was conducted for the IPCC Third Assessment Report (IPCC-TAR).

Development of a climate record of tropospheric and stratospheric column ozone from satellite remote sensing: evidence of an early recovery of global stratospheric ozone [PDF]

Atmospheric Chemistry and Physics, 2012
Ozone data beginning October 2004 from the Aura Ozone Monitoring Instrument (OMI) and Aura Microwave Limb Sounder (MLS) are used to evaluate the accuracy of the Cloud Slicing technique in effort to develop long data records of tropospheric and ...
