The potential to narrow uncertainty in projections of stratospheric ozone over the 21st century [PDF]

Atmospheric Chemistry and Physics, 2010
Future stratospheric ozone concentrations will be determined both by changes in the concentration of ozone depleting substances (ODSs) and by changes in stratospheric and tropospheric climate, including those caused by changes in anthropogenic greenhouse

Impact of climate variability on tropospheric ozone [PDF]

, 2007
A simulation with the climate–chemistry model (CCM) E39/C is presented, which covers both the troposphere and stratosphere dynamics and chemistry during the period 1960 to 1999.

Causes of interannual variability over the southern hemispheric tropospheric ozone maximum [PDF]

Atmospheric Chemistry and Physics, 2017
We examine the relative contribution of processes controlling the interannual variability (IAV) of tropospheric ozone over four sub-regions of the southern hemispheric tropospheric ozone maximum (SHTOM) over a 20-year period.

Effects of stratosphere-troposphere chemistry coupling on tropospheric ozone [PDF]

, 2010
[1] A new, computationally efficient coupled stratosphere-troposphere chemistry-climate model (S/T-CCM) has been developed based on three well-documented components: a 64-level general circulation model from the UK Met Office Unified Model, the ...

Stratospheric ozone in the post-CFC era [PDF]

Atmospheric Chemistry and Physics, 2009
Vertical and latitudinal changes in the stratospheric ozone in the post-chlorofluorocarbon (CFC) era are investigated using simulations of the recent past and the 21st century with a coupled chemistry-climate model.

The importance of interactive chemistry for stratosphere–troposphere coupling [PDF]

Atmospheric Chemistry and Physics, 2019
Recent observational and modeling studies suggest that stratospheric ozone depletion not only influences the surface climate in the Southern Hemisphere (SH), but also impacts Northern Hemisphere (NH) spring, which implies a strong interaction between ...

Correlating tropospheric column ozone with tropopause folds: the Aura-OMI satellite data [PDF]

Atmospheric Chemistry and Physics, 2010
The geographic and temporal variations in tropospheric and stratospheric ozone columns from individual swath measurements of the Ozone Monitoring Instrument (OMI), on the NASA Aura spacecraft, are reasonably well simulated by the University of California,

Chlorine Compounds and Stratospheric Ozone [PDF]

Science, 1975
A report by Cicerone et al. (1974) concerned with the potential size of the atmospheric perturbation produced by man-made chlorofluoromethanes is considered, giving attention to a number of errors made in the first investigation and their correction. However, the corrections do not significantly change the results reported.

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

Advanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

Simulation of Stratospheric Water Vapor Trends: Impact on Stratospheric Ozone Chemistry [PDF]

, 2004
A transient model simulation of the 40-year time period 1960 to 1999 with the coupled climate-chemistry model (CCM) ECHAM4.L39(DLR)/CHEM shows a stratospheric water vapor increase over the last two decades of 0.7 ppmv and, additionally, a short-term ...
